Item 1.	Business

Overview

We are a provider of mobile communication solutions focused on addressing critical communication challenges facing hospitals today. We help our customers improve patient safety and satisfaction, and increase hospital efficiency and productivity through our Voice Communication, Secure Messaging and Care Transition solutions. Our Voice Communication solution, which includes a lightweight, wearable, voice-controlled communication badge and a software platform, enables users to connect instantly with other hospital staff simply by saying the name, function or group name of the desired recipient. Our Secure Messaging solution securely delivers text messages and alerts directly to and from smartphones. Our hosted Care Transition solutions include voice and text based software applications that capture, manage and monitor patient information when responsibility for the patient is transferred or “handed-off” from one caregiver to another, which helps manage the hospital discharge process to help prevent unnecessary readmissions.

At the core of our Voice Communication solution is a patent-protected software platform that we introduced in 2002. We have significantly enhanced and added features and functionality to this solution through ongoing development based on frequent interactions with our customers. Our software platform is built upon a scalable architecture and recognizes more than 100 voice commands. Users can instantly communicate with others using the Vocera communication badge or through Vocera Connect client applications available for iPhone and Android smartphones, as well as Cisco wireless IP phones. Our Voice Communication solution can also be integrated with nurse call and other clinical systems to immediately and efficiently alert hospital workers to patient needs.

Our solutions are deployed in 875 hospitals and healthcare facilities, including large hospital systems, small and medium-sized local hospitals, and a small number of clinics, surgery centers and aged-care facilities. Over 1,000 customers, including non-healthcare users, have deployed our solutions. We sell our solutions to healthcare customers primarily through our direct sales force in the United States, and through direct sales and select distribution channels in international markets.

We were incorporated in Delaware on February 16, 2000. Our corporate headquarters are located at 525 Race Street, San Jose, CA 95126, and our main telephone number is (408) 882‑5100. We maintain a website at www.vocera.com. The contents of our website are not incorporated into, or otherwise to be regarded as part of, this Annual Report on Form 10-K.

Industry overview

Improving communication among the mobile and highly dispersed healthcare professionals in hospitals is extremely important. Hospital communications are typically conducted through disparate components, including overhead paging, pagers and mobile phones, often relying on written records of who is serving in specific roles during a particular shift. These legacy communication methods are inefficient, often unreliable, noisy and do not provide “closed loop” communication (in which a caller knows if a message has reached its intended recipient). These communication deficiencies can negatively impact patient

Table of Contents

safety, delay patient care and result in operational inefficiencies. Additionally, the increasing focus on improving patients' experience is supported by the healthcare reform initiative, which incorporates financial incentives for hospitals to improve the quality of care and patient satisfaction. These forces are driving hospitals to invest in technology and process improvements to manage their operations more efficiently and to improve staff and patient satisfaction. Our communication platform helps hospitals increase productivity and reduce costs by streamlining operations, and improves patient and staff satisfaction by creating a differentiated “Vocera hospital” experience.

Our strategy

Our goal is to extend our leadership position as a provider of communication solutions in the healthcare market. Key elements of our strategy include:

•

Expand our business to new U.S. healthcare customers. As of December 31, 2012, our solutions were deployed in approximately 10% of U.S. hospitals. We believe our unified communication platform can provide significant value to both large and small hospitals that currently do not deploy our solutions. We plan to continue to expand our direct sales force to win new customers among hospitals of all sizes. We have structured and incentivized our sales organization to focus on sales to new customer sites, particularly within large health systems.

•

Further penetrate our existing installed customer base. Typically, our customers initially deploy our Voice Communication solutions in a few departments of a hospital and gradually expand to additional departments as they come to fully appreciate the value of our solutions. We recognize the significant opportunity to up-sell and cross-sell to our existing customers, including into new hospitals that are part of healthcare system where our systems are deployed in one or more other hospitals. Key sales strategies include promoting a further adoption of our Voice Communication solution and demonstrating the value of our Secure Messaging and Care Transition solutions to our existing customers. We plan to continue expanding the number of account managers focused on our existing customers in order to grow our revenue and maintain and improve customer experience.

•

Extend our technology advantage and create new product solutions. We intend to continue our investment in research and development to enhance the functionality of our communication solutions and further differentiate them from other competing solutions. We plan to invest in product upgrades, product line extensions and new solutions to enhance our portfolio, such as our recent introduction of client applications for iPhone and Android mobile platforms.


•	Pursue acquisitions of complementary businesses, technologies and assets. We completed four small acquisitions in 2010 to expand our solutions offering, demonstrating that we can successfully source, acquire and integrate complementary businesses, technologies and assets. We intend to continue to pursue acquisition opportunities that we believe can accelerate the growth of our business.

•

Grow our international healthcare presence. Today, in addition to our core U.S. market, we sell primarily into other English-speaking markets, including Canada, the United Kingdom, Australia and New Zealand. As of December 31, 2012, our solutions were deployed in over 100 healthcare facilities outside the United States. We plan both to utilize our direct sales force and leverage channel partners to expand our presence in other English-speaking markets and enter non-English speaking countries. Recently we announced the general availability of a localized French language version of our Voice Communication solution.

•

Expand our communication solutions in non-healthcare markets. While our current focus is on the healthcare market, we believe that our communication solutions can also provide value in non-healthcare markets. Our Voice Communication and messaging solutions have been deployed in over 200 customers in non-healthcare markets where there are large numbers of mobile workers, including hospitality, retail and libraries. Currently, this is not a material portion of our business, but longer term, we believe these markets could represent potential opportunities for growth.

Our products, technology and services

Our solutions consist of our Voice Communication, Secure Messaging and Care Transition solutions. To complement our solutions, we provide services and support capabilities to help our customers optimize the benefits of our solutions.

Voice Communication solution

Our Voice Communication solution is comprised of a unique software platform that connects communication devices, including our hands-free, wearable, voice-controlled communication badges and third-party mobile devices that use our software applications to become part of the Vocera system. The system transforms the way mobile workers communicate by enabling them to instantly connect with the right person simply by saying the name, function or group name of the person they want to reach, often while remaining at the point-of-care. Our system responds to over 100 voice commands.

Some examples of common commands are shown below.

Table of Contents



Action		Spoken commands
Call by name		Call John Smith.

Call a group member		Call an Anesthesiologist.

Dial a phone number or extension		Dial extension 3145.

Initiate a broadcast to a group		Broadcast to Emergency Response Team.

Locate nearest member of a group		Where is the nearest member of Security?

Send a voice message		Record a message for Pediatric Nursing.

Components of the Voice Communication solution include:

•

Software platform. At the heart of our Voice Communication solution is a patent-protected enterprise-class software platform that runs on our customers’ Windows-based servers. The intelligence of our client-server system is contained primarily within our server-software. This platform contains an optimized speech recognition engine and call management functionality. In addition, it controls the calling and messaging functions of the mobile client devices and maintains profiles for users and groups that enable customization of workflow patterns for each customer. Our scalable software platform can support multiple geographic sites and multiple facilities within a healthcare system to help clinicians stay connected to the latest status of their patients.

In addition to the primary system server, our software platform includes usage and diagnostic reporting tools, as well as our telephony software to interface to customers’ existing phone systems. Our solution is further embedded into the clinical workflow of the hospital through the ability to integrate with over 50 third-party clinical systems, including nurse call, patient monitoring and electronic medical record systems. These integrated solutions enable the immediate delivery of alerts to hospital workers, helping to improve patient safety and satisfaction.

•

Communication badge. Our communication badge is a wearable device weighing less than two ounces that operates over customers’ industry-standard Wi-Fi networks, the use of which has become increasingly prevalent in hospitals. The badge is worn clipped to a shirt or on a lanyard. It can be used to conduct hands-free communication and is the only hands-free device of its kind. It enables instant two-way voice conversations without the need to remember a phone number or use a handset. An over-the-air update mechanism seamlessly updates device software. Our badge also incorporates automatic diagnostic mechanisms that feed data on wireless network performance back to the software platform for reporting and diagnosis of problems. In October 2011, we introduced the Vocera B3000 badge, our fourth generation communication badge. This badge offers improved durability, a louder speaker for noisy environments and proprietary acoustic noise reduction technology to improve speech recognition by eliminating background noise.

•

Vocera Connect mobile applications. Vocera Connect mobile applications allow Vocera customers to enable authorized users to access the voice calling capability of our system on third-party mobile devices, including iPhone, Android and other mobile devices. In 2012, we added Cisco wireless IP phones to the list of mobile devices we support. When used in a Wi-Fi environment, the Vocera Connect mobile application enables non-Vocera devices to receive voice communication initiated within the Vocera system, including role-based calls and group broadcasts. Onscreen presence information enables users to see the status of other users and instantly connect with particular individuals, functional roles or entire groups using voice commands or our click-to-connect functionality.

Secure Messaging solution

Our Secure Messaging solution securely delivers text messages, alerts and other information, directly to and from smartphones. It is designed to replace paging and unsecure short message service, or SMS, systems. Our solution is comprised of an enterprise-grade software platform and client applications that run on iPhone or Android devices. The software platform provides the central intelligence, database of users and contacts and monitoring controls that display a real-time dashboard of delivery, receipt confirmations and responses. Our Secure Messaging solution includes a range of client applications, including Alert, Chat, Content and Contacts, to meet the specific needs of hospitals and other enterprise environments.

Our Vocera Alert application is a smartphone client application that works in conjunction with our messaging platform to ensure timely, reliable and encrypted delivery (as recommended by applicable HIPAA regulations) and acknowledgment of critical messages, including pages, lab test results and other alerts. Users can send messages to the smartphones of other users or groups from a smartphone, web console or automatically through integration with third-party clinical systems, like nurse call and patient monitoring systems. Recipients can reply with multiple choice answers or custom responses, and a reporting tool tracks and stores all of the transactions for auditing purposes. Our Alert application replaces unreliable pagers that have been used in hospitals for decades with reliable closed loop message delivery.

Care Transition Solution

Our Care Transition solution is a hosted voice and text based software application that captures, manages and monitors patient information when responsibility for the patient is transferred or “handed-off” from one caregiver to another. Our platform, which includes modules for patient transfers, shift changes, patient discharge instructions and patient and family information exchanges, allows hospitals to effectively standardize and monitor patient hand-offs. The solution streamlines patient hand-offs in a secure, manageable, web-enabled manner that enables caregivers to capture and transfer important information about patients in either written or voice recorded formats from any phone or PC.

Our secure web interface provides real-time monitoring of hand-off quality, compliance and throughput. Caregivers can access the application through a variety of end-points, including computers, smartphones and other wireless devices. The solution alerts the receiving unit of the patient’s anticipated arrival, along with care instructions left by the previous caregiver. This eliminates phone tag and paperwork and reduces miscommunication that can cause delays and errors in patient transfers. We have also introduced a patient discharge solution, Good to Go, that helps manage the discharge process and provides patients better information in order to help prevent unnecessary readmissions.

Our Care Transition solution can be deployed through either a hosted software-as-a-service model or as a server-on-site model.

Services

Our customer-centric strategy is supported by our services and support capabilities, which help customers optimize their Vocera experience. Our services organization consists of the following:

•

ExperiaHealth. ExperiaHealth is focused on improving patient experience. ExperiaHealth works with hospitals and other healthcare organizations to improve clinical and operational performance that results in improved efficiency, work flow and enhanced patient experience. Services offered by ExperiaHealth include: consulting with customers to improve organizational alignment around patient experience strategy and priorities, developing process improvement plans to increase patient and caregiver satisfaction, providing training modules on topics such as physician leadership coaching, developing clinical service line experience mapping, and leading patient experience improvement and service recovery training.

•

Professional services. Our professional services are key to helping customers successfully deploy, manage, update and/or expand their Vocera systems in order to gain the full benefits of our solutions. As of December 31, 2012, our professional services team consisted of 42 professionals with expertise in wireless communication, clinical workflow, end-user training, speech science and project management, about half of whom are nurses who understand and can help overcome the challenges of clinical communication issues. We offer a full suite of services, including clinical workflow design, wireless assessment, solution configuration, training and project management, enabling customers to integrate our solutions and improve workflow efficiency and staff productivity. We also provide classroom and distance learning curricula for systems administrators, information technology professionals and clinical educators.

•

Technical support. We provide 24x7 technical support to our customers through our support centers in San Jose, California; Toronto, Canada; Knoxville, Tennessee and Reading, United Kingdom. As of December 31, 2012, our technical support team consisted of 38 technical support professionals with expertise in wireless, telephony, integration, servers and client devices. Our team utilizes remote diagnostic tools to proactively assess the performance of customer systems. Each support center includes bilingual French/English engineers. We assign technical account management resources to our largest accounts to help them expand the use of our solutions and facilitate adoption of new functionality. Additional services, including an annual Remote System Health Assessment and biweekly technical webinar education, are offered as project-based consulting or through our membership collaborative.

Sales and marketing

Sales

We use a direct sales model to call on hospitals and healthcare systems in the United States, the United Kingdom, Australia and New Zealand. As of December 31, 2012, we had 90 sales employees. The sales team is organized to allow us to better serve our customers and to support the different elements of our sales strategy. Certain members of the sales team focus on the development of new customer relationships with large integrated health systems and government healthcare facilities. Our compensation is structured to incentivize new account development, including a bonus commission paid for new customers. We supplement our sales organization by utilizing a U.S. government-authorized reseller to facilitate our sales to Veterans Administration and Department of Defense healthcare facilities. Sales team members also focus on new customer development with smaller systems and individual hospitals. The sales team further includes account managers who focus on service and additional sales to existing customers. We enhance our sales efforts by including in our sales staff individuals with nursing backgrounds to address clinical uses with, and provide utilization advice to, customers and potential customers. We have also

Table of Contents

staffed our sales team with system engineers who focus on the technical elements of system optimization, particularly wireless, and overall product configuration.

We strive to hire sales people with at least 10 years of experience selling enterprise solutions in healthcare and who have experience selling in competitive and complex environments with multiple decision makers. In markets outside the United States, our sales efforts are supplemented by a select group of resellers and distributors.

In addition, as of December 31, 2012, we had 23 employees responsible for sales and services support.

Marketing

Our marketing efforts focus on product management, demand generation, sales support and brand management. We believe continuing to increase our brand recognition is important for the growth of our business. As of December 31, 2012, we had 23 employees in marketing and business development.

Our product roadmap and requirements are driven by both primary and secondary research that is continually validated with current and prospective customers. We collect customer feedback through surveys and focus groups, customer visits, a customer advisory board, user forums and participation in industry standards organizations. Our customer-centric marketing strategy is key to generating new sales leads as word of mouth advertising and testimonials are some of our most valuable marketing tools. A number of our customers have agreed to participate in video testimonials, white papers and case studies that validate the efficacy and the financial benefits of our solutions. We have been featured in numerous articles and on network television demonstrating increased patient satisfaction, streamlined hospital operations and enhanced employee safety. Additionally, we sponsor numerous customer-led webinars to demonstrate customer success and to let prospective customers hear from their peer group about the positive impact that our solutions have made on their hospitals. Many of our sales leads come from referrals of existing customers or users who have moved from a hospital already using Vocera to a new facility or health system.

Demand generation is created through high touch activities across multiple platforms including print media, phone, direct mail and e-mail campaigns and participation in tradeshows and other industry sponsored events. We use a variety of sales tools with prospective customers including collateral, ROI calculators and product videos and presentations.

We received the exclusive endorsement of AHA Solutions, a subsidiary of the American Hospital Association, for our Voice Communication and Care Transition solutions. As part of this endorsement, we are able to participate in customer events sponsored by AHA Solutions. Further, we believe hospital customers view this endorsement as a validation of the quality of our solutions.

Customers

Our customers include 875 hospitals and other healthcare facilities, of which over 100 are outside of the United States. In addition, we have deployed our Voice Communication solution in over 200 customers in other vertical markets. Our healthcare customer base spans hospital networks, research and academic centers, small and medium-sized local hospitals and international hospitals. Our customers include Alberta Health Systems, Banner Health System, University of California’s Davis Medical Center, El Camino Hospital, NorthShore University Health System, OhioHealth and Texas Health Resources. Our diverse customer base has very low customer revenue concentration. During 2012, our largest end customer represented only 2.7% of revenue.

Currently, we sell into English speaking markets including the United States, Canada, the United Kingdom, Australia and New Zealand. During 2012 and 2011, non-U.S. markets represented approximately 10.7% and 7.3% of our revenue, respectively. In addition to our recent introduction of a localized French language version of our Voice Communication solution, we are developing plans to offer our solutions in a wider range of international markets including other non-English speaking countries.

Competition

We do not believe any single competitor offers an intelligent voice communication system to the healthcare market that allows instant, hands-free communication through voice-activated, role-based and activity-based calling using a combination of dedicated, proprietary devices as well as accommodating the use of third-party smartphones and other devices.

At this time, the primary alternative to our system consists of traditional communication methods utilizing wired phones, Wi-Fi in-building phones, pagers and overhead intercoms. The most significant alternatives to the traditional communication system with which we compete for sales in the hospital are in-building wireless telephones. While we compete with the providers of these wireless phones in making sales to hospitals, they do not at this time purport to contain the system intelligence and convenience of our Voice Communication solution. The market for in-building wireless phones is dominated by large communications companies such as Cisco Systems, Ascom and Spectralink.

Table of Contents

We believe that the primary competitive factors at work in our market include:


•	comprehensiveness of the solution and the features provided


•	product performance and reliability


•	the initial cost and ongoing cost of ownership


•	customer service and support capabilities

We may face increased competition in the future, including competition from large, multinational companies with significant resources. Potential competitors may have existing relationships with purchasers of other products and services within the hospital, which may enhance their ability to gain a foothold in our market.

Research and development

Our continued investment in research and development is critical to our business. We have assembled teams of engineers with expertise in various fields, including software, firmware, database design, applications, speech recognition, wireless communication and hardware design. We have research and development personnel in San Jose, California; Knoxville, Tennessee and Toronto, Canada. There were 59 full-time research and development employees as of December 31, 2012. We also utilize small teams of contractors in India and the Ukraine to assist with quality assurance testing and automation, and targeted development efforts. Our research and development expenditures were $11.6 million, $9.3 million and $6.7 million in 2012, 2011 and 2010, respectively.

Intellectual property

Our success depends, in part, upon our ability to protect our core technology and intellectual property. To accomplish this, we rely on a combination of intellectual property rights, including patents, trade secrets, copyrights and trademarks, as well as customary contractual protections.

We have been granted 16 U.S. patents, including patents on many capabilities of our software platform and communication badge. The expiration dates of these patents range from 2018 through 2029. One or more utility patents have also been issued in Australia, Canada, India, Japan and the European Patent Office (with validation in Germany, France, the United Kingdom and the Netherlands.) A European Community design patent has been issued that protects the design in multiple European jurisdictions. We have five patent applications pending in the United States, and one or more utility patent applications are pending in Canada and at the European Patent Office. Our primary registered trademark in the United States is Vocera^®.

In addition to the foregoing protections, we generally control access to and use of our proprietary software and other confidential information through the use of internal and external controls, including contractual protections with employees, contractors, customers and partners. Our software is also protected by U.S. and international copyright laws.

Our solutions include software developed and owned by us as well as software components we have licensed. These non-exclusive licenses are terminable by the licensor for cause. Certain of these licenses are for a contractually specified term and cannot be renewed without the assent of the licensor. In the event one or more of these licenses is terminated or is not renewed, we could be required to redesign substantial portions of our software in order to incorporate software components from alternative sources. An unplanned redesign of our software could materially and adversely affect our business.

Manufacturing operations and suppliers

We outsource the manufacturing of our device products to original design manufacturers and a contract manufacturer, SMTC. Our communication badge is currently built in Mexico using custom tools and test equipment owned by us. Initial volumes of new products may be manufactured by our contract manufacturer in U.S. facilities. Most of our accessories, including batteries, chargers and attachments, are built by original design manufacturers in Asia.

These manufacturers are responsible for procuring all the components included in our products as specified and approved by us. Some of these components are sole-sourced off-the-shelf and some are custom components built exclusively for our products. In the event we are unable to procure certain components, we could be required to redesign some of our products in order to incorporate technology from alternative sources. An unplanned redesign of our products could materially and adversely affect our business.

We require our suppliers to perform both incoming and outgoing product inspections. In addition, we perform in-house quality control and ongoing reliability testing.

Table of Contents

Employees

As of December 31, 2012, we had 343 employees, consisting of 24 in manufacturing and quality operations, 59 in research and development, 136 in sales and marketing, 80 in services and 44 in general and administrative. None of our employees are covered by a collective bargaining agreement or are represented by a labor union. We consider current employee relations to be good.

Government regulations and standards

Substantially all of our revenue is derived from the healthcare industry. The healthcare industry is highly regulated and is subject to changing political, legislative, regulatory and other influences. These factors affect the purchasing practices and operations of healthcare organizations, as well as the behavior and attitudes of our users. Healthcare reform has been recently enacted at the federal level. We expect federal and state legislatures and agencies to continue to consider programs to reform or revise aspects of the U.S. healthcare system. These programs may contain proposals to increase governmental involvement in healthcare or otherwise change the environment in which healthcare industry participants operate.

HIPAA privacy and security standards

In connection with our healthcare communications business, we handle and have access to personal health information on behalf of our customers. Accordingly, in the United States, we are subject to HIPAA and its implementing regulations, which established uniform standards for certain “covered entities” (healthcare providers engaged in electronic transactions, health plans and healthcare clearinghouses) governing the conduct of certain electronic healthcare transactions and protecting the security and privacy of protected health information. The American Recovery and Reinvestment Act of 2009 included sweeping expansion of HIPAA’s privacy and security standards as reflected in the HITECH Act. Among other things, the new law makes certain HIPAA privacy and security standards directly applicable to “business associates”—independent contractors or agents of covered entities that receive or obtain protected health information in connection with providing a service on behalf of a covered entity. HITECH also increased the civil and criminal penalties that may be imposed against covered entities, business associates and possibly other persons, and gave state attorneys general new authority to file civil actions for damages or injunctions in federal courts to enforce the federal HIPAA laws and seek attorney’s fees and costs associated with pursuing federal civil actions. Most of our customers are covered entities under HIPAA and, to the extent that we handle personal health information on their behalf, we are their “business associates” and are subject to HIPAA and associated contractual obligations, as well as comparable state privacy and security laws.

In addition, we are subject to privacy and security regulations in other jurisdictions. For example, the EU adopted the DPD imposing strict regulations and establishing a series of requirements regarding the storage of personally identifiable information on computers or recorded on other electronic media. This has been implemented by all EU member states through national laws. DPD provides for specific regulations requiring all non-EU countries doing business with EU member states to provide adequate data privacy protection when receiving personal data from any of the EU member states. Similarly, Canada’s Personal Information and Protection of Electronic Documents Act provides Canadian residents with privacy protections in regard to transactions with businesses and organizations in the private sector and sets out ground rules for how private sector organizations may collect, use and disclose personal information in the course of commercial activities.

These statutes, regulations and contractual obligations impose numerous requirements regarding the use and disclosure of personal health information with which we must comply, and subject us to material liability and other adverse impacts to our business in the event we fail to do so. These include, without limitation, civil fines, criminal sanctions in certain circumstances, contractual liability to our customer, and damage to our brand and reputation. We endeavor to mitigate these risks through measures we believe to be appropriate for the specific circumstances, including storing personal data under our control on password-protected systems in secure facilities, counseling our customers as to best practices in using our solutions, and encrypting such information.

Medical device regulation

The FDA regulates certain products, including software-based products, as “medical devices” based, in part, on the intended use of the product and the risk the device poses to the patient should the device fail to perform properly. Although we have concluded that our products are general-purpose communication devices not subject to FDA regulation, either the FDA could disagree with our conclusion or changes in our product or the FDA’s evolving regulations could lead to the imposition of medical device regulation on our products. In this event, we would be subject to extensive regulatory requirements, including the expense of compliance with Medical Device Reporting and Quality System regulation and the potential of liability for failure to comply, and we could be required to obtain 510(k) clearance or premarket approval of our products from the FDA prior to commercial distribution. Further, we would be subject to the 2.3% excise tax that became applicable to medical devices beginning January 2013.

Electrical standards and FCC regulations

Our products emit radio frequency energy in the 2.4 GHz spectrum band for which licensing by U.S. and other regulatory authorities is not required, provided that the products conform to certain requirements, e.g., maximum power output and tolerance of interference from other devices sharing that spectrum band. We subject our products to testing by independent testing laboratories for compliance with the relevant standards issued by various U.S. and international bodies, including the European Union (with respect to the “CE” mark), the International Electrotechnical Commission, the Australian Communications and Media Authority, Underwriters Laboratories and CSA International.

Item 1A.	Risk Factors

Investing in our common stock involves a high degree of risk. You should carefully consider the risks and uncertainties described below, together with all of the other information set forth in this Annual Report on Form 10-K. Our business, financial condition, results of operations or future prospects could be materially and adversely harmed if any of the following risks, or other risks or uncertainties that are not yet identified or that we currently believe are immaterial, actually occur. The trading price of our common stock could decline due to any of these risks or uncertainties, and, as a result, you may lose all or part of your investment.

Risks related to our business and industry

Although we reported net income for the year ended December 31, 2012, we have incurred significant losses in the past. If we cannot maintain profitability, our business will be harmed and our stock price could decline.

We have incurred significant losses in the past and may incur losses in the future as we continue to grow our business. As of December 31, 2012, we had an accumulated deficit of $54.0 million. We expect our expenses to increase due to the hiring of additional personnel and the additional operational and reporting costs associated with being a public company. We reported net income for year ended December 31, 2012. However, if we cannot maintain profitability, our business will be harmed and our stock price could decline.

Our ability to be profitable in the future depends upon continued demand for our communication solutions from existing and new customers. Further market adoption of our solutions, including increased penetration within our existing customers, depends upon our ability to improve patient safety and satisfaction and increase hospital efficiency and productivity. In addition, our profitability will be affected by, among other things, our ability to execute on our business strategy, the timing and size of orders, the pricing and costs of our solutions, and the extent to which we invest in sales and marketing, research and development and general and administrative resources.

We depend on sales of our Voice Communication solution in the healthcare market for substantially all of our revenue, and any decrease in its sales would harm our business.

To date, substantially all of our revenue has been derived from sales of our Voice Communication solution to the healthcare market and, in particular, hospitals. Any decrease in revenue from sales of our Voice Communication solution would harm our business. For 2012 and 2011, sales of our Voice Communication solution to the healthcare market accounted for 92% and 91% of our revenue, respectively. In addition, we obtained a significant portion of these sales from existing hospital customers. We

Table of Contents

anticipate that sales of our Voice Communication solution will represent a significant portion of our revenue for the foreseeable future. While we are evaluating new solutions for non-healthcare markets, we may not be successful in applying our technology to these markets. In any event, we do not anticipate that sales of our Voice Communication solution in non-healthcare markets will represent a significant portion of our revenue for the foreseeable future.

Our success depends in part upon the deployment of our Voice Communication solution by new hospital customers, the expansion and upgrade of our solution at existing customers, and our ability to continue to provide on a timely basis cost-effective solutions that meet the requirements of our hospital customers. Our Voice Communication solution requires a substantial upfront investment by customers. Typically, our hospital customers initially deploy our solution for specific users in specific departments before expanding our solution into other departments or for other users. The cost of the initial deployment depends on the number of users and departments involved, the size and age of the hospital and the condition of the existing wireless infrastructure, if any, within the hospital.

Even if hospital personnel determine that our Voice Communication solution provides compelling benefits over their existing communications methods, their hospitals may not have, or may not be willing to spend, the resources necessary to install and maintain wireless infrastructure to initially deploy and support our solution or expand our solution to other departments or users. Hospitals are currently facing significant budget constraints, ever increasing demands from a growing number of patients and impediments to obtaining reimbursements for their services. In addition, hospitals funded by the U.S. government are experiencing budgeting issues due to the ongoing effects of and uncertainty around the U.S. government sequestration and debt ceiling issues, and as a consequence, we may continue to experience a slowdown and deferral of orders for our Voice Communication solution that could negatively impact our sales. We believe hospitals are currently allocating funds for capital and infrastructure improvements to benefit from recently enacted electronic medical records incentives, which may impact their ability to purchase and deploy our solution. We might not be able to sustain or increase our revenue from sales of our Voice Communication solution, or achieve the growth rates that we envision, if hospitals continue to face significant budgetary constraints and reduce their spending on communications systems.

Our sales cycle can be lengthy and unpredictable, which may cause our revenue and operating results to fluctuate significantly.

Our sales cycles can be lengthy and unpredictable. Our sales efforts involve educating our customers about the use and benefits of our solutions, including the technical capabilities of our solutions and the potential cost savings and productivity gains achievable by deploying them. Customers typically undertake a significant evaluation process, which frequently involves not only our solutions but also their existing communications methods and those of our competitors, and can result in a lengthy sales cycle of nine to twelve months or more. We spend substantial time, effort and money in our sales efforts without any assurance that our efforts will produce any sales. In addition, purchases of our solutions are frequently subject to budget constraints, multiple approvals, and unplanned administrative, processing and other delays. As a result, our revenue and operating results may vary significantly from quarter to quarter.

If we fail to increase market awareness of our brand and solutions, and expand our sales and marketing operations, our business could be harmed.

We intend to continue to add personnel and resources in sales and marketing as we focus on expanding awareness of our brand and solutions and capitalize on sales opportunities with new and existing customers. Our efforts to improve sales of our solutions will result in an increase in our sales and marketing expense and general and administrative expense, and these efforts may not be successful. Some newly hired sales and marketing personnel may subsequently be determined to be unproductive and have to be replaced, resulting in operational and sales delays and incremental costs. If we are unable to significantly increase the awareness of our brand and solutions or effectively manage the costs associated with these efforts, our business, financial condition and operating results could be harmed.

If we fail to offer high-quality services and support for any of our solutions, our ability to sell those solutions will be harmed.

Our ability to sell our Voice Communication, Secure Messaging or Care Transitions solutions is dependent upon our professional services and technical support teams providing high-quality services and support. Our professional services team assists our customers with their wireless infrastructure assessment, clinical workflow design, communication solution configuration, training and project management during the pre-deployment and deployment stages. Once our solutions are deployed within a customer’s facility, the customer typically depends on our technical support team to help resolve technical issues, assist in optimizing the use of our solutions and facilitate adoption of new functionality. If we do not effectively assist our customers in deploying our solutions, succeed in helping our customers quickly resolve technical and other post-

Table of Contents

deployment issues, or provide effective ongoing support services, our ability to expand the use of our solutions with existing customers and to sell our solutions to new customers will be harmed. If deployment of our solutions is unsatisfactory, as has been the case with certain third-party deployments in the past, we may incur significant costs to attain and sustain customer satisfaction. As we rapidly hire new services and support personnel, we may inadvertently hire underperforming people who will have to be replaced, or fail to effectively train such employees, leading in some instances to slower growth, additional costs and poor customer relations. In addition, the failure of channel partners to provide high-quality services and support in markets outside the United States could also harm sales of our solutions.

We depend on a number of sole source and limited source suppliers, and if we are unable to source our components from them, our business and operating results could be harmed.

We depend on sole and limited source suppliers for several hardware components of our Voice Communication solution, including our batteries and integrated circuits. We purchase inventory generally through individual purchase orders. Any of these suppliers could cease production of our components, experience capacity constraints, material shortages, work stoppages, financial difficulties, cost increases or other reductions or disruptions in output, cease operations or be acquired by, or enter into exclusive arrangements with, a competitor. These suppliers typically rely on purchase orders rather than long-term contracts with their suppliers, and as a result, even if available, the supplier may not be able to secure sufficient materials at reasonable prices or of acceptable quality to build our components in a timely manner. Any of these circumstances could cause interruptions or delays in the delivery of our solutions to our customers, and this may force us to seek components from alternative sources, which may not have the required specifications, or be available in time to meet demand or on commercially reasonable terms, if at all. Any of these circumstances may also force us to redesign our solutions if a component becomes unavailable in order to incorporate a component from an alternative source.

Our solutions incorporate multiple software components obtained from licensors on a non-exclusive basis, such as voice recognition software, software supporting the runtime execution of our software platform, and database and reporting software. Our license agreements can be terminated for cause. In many cases, these license agreements specify a limited term and are only renewable beyond that term with the consent of the licensor. If a licensor terminates a license agreement for cause, objects to its renewal or conditions renewal on modified terms and conditions, we may be unable to obtain licenses for equivalent software components on reasonable terms and conditions, including licensing fees, warranties or protection from infringement claims. Some licensors may discontinue licensing their software to us or support of the software version used in our solutions. In such circumstances, we may need to redesign our solutions at substantial cost to incorporate alternative software components or be subject to higher royalty costs. Any of these circumstances could adversely affect the cost and availability of our solutions.

Third-party licensors generally require us to incorporate specific license terms and conditions in our agreements with our customers. If we are alleged to have failed to incorporate these license terms and conditions, we may be subject to claims by these licensors, incur significant legal costs defending ourselves against such claims and, if such claims are successful, be subject to termination of licenses, monetary damages, or an injunction against the continued distribution of one or more of our solutions.

Because we depend upon a contract manufacturer, our operations could be harmed and we could lose sales if we encounter problems with this manufacturer.

We do not have internal manufacturing capabilities and rely upon a contract manufacturer, SMTC Corporation, to produce the primary hardware component of our Voice Communication solution. We have entered into a manufacturing agreement with SMTC that is terminable by either party with advance notice and that may also be terminated for a material uncured breach. We also rely on original design manufacturers, or ODMs, to produce accessories, including batteries, chargers and attachments. If SMTC or an ODM is unable or unwilling to continue manufacturing components of our solutions in the volumes that we require, fails to meet our quality specifications or significantly increases its prices, we may not be able to deliver our solutions to our customers with the quantities, quality and performance that they expect in a timely manner. As a result, we could lose sales and our operating results could be harmed.

SMTC or ODMs may experience problems that could impact the quantity and quality of components of our Voice Communication solution, including disruptions in their manufacturing operations due to equipment breakdowns, labor strikes or shortages, component or material shortages and cost increases. SMTC and these ODMs generally rely on purchase orders rather than long-term contracts with their suppliers, and as a result, may not be able to secure sufficient components or other materials at reasonable prices or of acceptable quality to build components of our solutions in a timely manner. The majority of the components of our Voice Communication solution are manufactured in Asia or Mexico and adverse changes in political or economic circumstances in those locations could also disrupt our supply and quality of components of our solutions. In October

Table of Contents

2011, we introduced the B3000 badge. Initial production of this product commenced with SMTC in the United States, and new production fully transitioned to Mexico in May 2012. Companies occasionally encounter unexpected difficulties in ramping up production of new products, and we may experience such difficulties with future generations of our products. SMTC and our ODMs also manufacture products for other companies. Generally, our orders represent a relatively small percentage of the overall orders received by SMTC and these ODMs from their customers; therefore, fulfilling our orders may not be a priority in the event SMTC or an ODM is constrained in its ability to fulfill all of its customer obligations. In addition, if SMTC or an ODM is unable or unwilling to continue manufacturing components of our solutions, we may have to identify one or more alternative manufacturers. The process of identifying and qualifying a new contract manufacturer or ODM can be time consuming, and we may not be able to substitute suitable alternative manufacturers in a timely manner or at an acceptable cost. Additionally, transitioning to a new manufacturer may cause us to incur additional costs and delays if the new manufacturer has difficulty manufacturing components of our solutions to our specifications or quality standards.

If we fail to forecast our manufacturing requirements accurately, or fail to properly manage our inventory with our contract manufacturer, we could incur additional costs and experience manufacturing delays, which can adversely affect our operating results.

We place orders with our contract manufacturer, SMTC, and we and SMTC place orders with suppliers based on forecasts of customer demand. Because of our international low cost sourcing strategy, our lead times are long and cause substantially more risk to forecasting accuracy than would result were lead times shorter. Our forecasts are based on multiple assumptions, each of which may introduce errors into our estimates affecting our ability to meet our customers' demands for our solutions. We also may face additional forecasting challenges due to product transitions in the components of our solutions, or to our suppliers discontinuing production of materials and subcomponents required for our solutions. If demand for our solutions increases significantly, we may not be able to meet demand on a timely basis, and we may need to expend a significant amount of time working with our customers to allocate limited supply and maintain positive customer relations, or we may incur additional costs in order to source additional materials and subcomponents to produce components of our solutions or to expedite the manufacture and delivery of additional inventory. If we underestimate customer demand, our contract manufacturer may have inadequate materials and subcomponents on hand to produce components of our solutions, which could result in manufacturing interruptions, shipment delays, deferral or loss of revenue, and damage to our customer relationships. Conversely, if we overestimate customer demand, we and SMTC may purchase more inventory than required for actual customer orders, resulting in excess or obsolete inventory, thereby increasing our costs and harming our operating results.

If hospitals do not have and are not willing to install, upgrade and maintain the wireless infrastructure required to effectively operate our Voice Communication solution, then they may experience technical problems or not purchase our solution at all.

The effectiveness of our Voice Communication solution depends upon the quality and compatibility of the communications environment that our healthcare customers maintain. Our solutions require voice-grade wireless, or Wi-Fi, installed through large enterprise environments, which can vary from hospital to hospital and from department to department within a hospital. Many hospitals have not installed a voice-grade wireless infrastructure. If potential customers do not have a wireless network that can properly and fully interoperate with our Voice Communication solution, then such a network must be installed, or an existing Wi-Fi network must be upgraded or modified, for example, by adding access points in stairwells, for our Voice Communication solution to be fully functional. The additional cost of installing or upgrading a Wi-Fi network may dissuade potential customers from installing our solution. Furthermore, if changes to a customer's physical or information technology environment cause integration issues or degrade the effectiveness of our solution, or if the customer fails to upgrade or maintain its environment as may be required for software releases or updates or to ensure our solution's effectiveness, the customer may not be able to fully utilize our solution or may experience technical problems, or these changes may impact the performance of other wireless equipment being used. If such circumstances arise, prospective customers may not purchase or existing customers may not expand their use of or deploy upgraded versions of our Voice Communication solution, thereby harming our business and operating results.

If we fail to achieve and maintain certification for certain U.S. federal standards, our sales to U.S. government customers will suffer.

We believe that a significant opportunity exists to sell our products to healthcare facilities in the Veterans Administration and Department of Defense, or DoD. These customers require independent certification of compliance with particular requirements relating to encryption, security, interoperability and scalability. These requirements include compliance with Federal Information Processing Standard, or FIPS, 140-2 and, as to DoD facilities, certification by the Joint Interoperability and Test Command of DoD and under the DoD Information Assurance Certification and Accreditation Process. We have received certification under certain of these standards for a military-specific configuration of the Vocera communication solution

Table of Contents

incorporating the B2000 badge. We are carrying out activities intended to achieve additional certifications, including certifications applicable to the B3000 badge and future products as well. A failure on our part to comply in a timely manner with these requirements, or to maintain certification, both as to current products and as to new product versions, could adversely impact our revenue.

Our Mobility Business Unit may not be successful in selling our communications solutions in non-healthcare markets.

Our primary focus has been on selling our communications solutions to the healthcare market, with other markets addressed only opportunistically. We have very recently created our Mobility Business Unit for sales efforts to customers outside the healthcare market, and it will initially focus on customers in selected industries. We may not be successful in further penetrating the non-healthcare markets upon which we are initially focusing, or other new markets. Our Voice Communication solution has been deployed in over 200 customers in non-healthcare markets, including hospitality, retail and libraries. Total revenue from non-healthcare customers accounted for 3% of our revenue in both 2012 and 2011, respectively. If we cannot maintain these customers by providing communications solutions that meet their requirements, if we cannot successfully expand our communications solutions in non-healthcare markets, or if our solutions are adopted more slowly than we anticipate, we may not obtain significant revenue from these markets. We may experience challenges as we expand in non-healthcare markets, including pricing pressure on our solutions and technical issues as we adapt our solutions for the requirements of new markets. Our communications solutions also may not contain the functionality required by these non-healthcare markets or may not sufficiently differentiate us from competing solutions such that customers can justify deploying our solutions.

If we fail to successfully develop and introduce new solutions and features to existing solutions, our revenue, operating results and reputation could suffer.

Our success depends, in part, upon our ability to develop and introduce new solutions and features to existing solutions that meet existing and new customer requirements. We may not be able to develop and introduce new solutions or features on a timely basis or in response to customers’ changing requirements, or that sufficiently differentiate us from competing solutions such that customers can justify deploying our solutions. We may experience technical problems and additional costs as we introduce new features to our software platform, deploy future models of our wireless badges and integrate new solutions with existing customer clinical systems and workflows. In addition, we may face technical difficulties as we expand into non-English speaking countries and incorporate non-English speech recognition capabilities into our Voice Communication solution. Our recently introduced B3000 badge has reduced demand for our existing B2000 badges, and we must therefore successfully manage the transition from existing badges, avoid excessive inventory levels and ensure that sufficient supplies of new badges can be delivered to meet customer demand. We also may incur substantial costs or delays in the manufacture of the B3000 badge and any additional new products or models as we seek to optimize production methods and processes at our contract manufacturer. In addition, we expect that we will at least initially achieve lower gross margins on new models, while endeavoring to reduce manufacturing costs over time. If any of these problems were to arise, our revenue, operating results and reputation could suffer.

If we do not achieve the anticipated strategic or financial benefits from our acquisitions or if we cannot successfully integrate them, our business and operating results could be harmed.

We have acquired, and in the future may acquire, complementary businesses, technologies or assets that we believe to be strategic, such as our four acquisitions completed in 2010. We may not achieve the anticipated strategic or financial benefits, or be successful in integrating any acquired businesses, technologies or assets. If we cannot effectively integrate our Voice Communication solution with our Secure Messaging and Care Transition solutions and successfully market and sell these solutions, we may not achieve market acceptance for, or significant revenue from, these new solutions.

Integrating newly acquired businesses, technologies and assets could strain our resources, could be expensive and time consuming, and might not be successful. Our 2010 acquisitions exposed us and we will be further exposed, if we acquire or invest in additional businesses, technologies or assets, to a number of risks, including that we may:


•	experience technical issues as we integrate acquired businesses, technologies or assets into our existing communications solutions;


•	encounter difficulties leveraging our existing sales and marketing organizations, and direct sales channels, to increase our revenue from acquired businesses, technologies or assets;


•	find that the acquisition does not further our business strategy, we overpaid for the acquisition or the economic conditions underlying our acquisition decision have changed;


•	have difficulty retaining the key personnel of acquired businesses;

Table of Contents


•	suffer disruption to our ongoing business and diversion of our management's attention as a result of transition or integration issues and the challenges of managing geographically or culturally diverse enterprises; and


•	experience unforeseen and significant problems or liabilities associated with quality, technology and legal contingencies relating to the acquisition, such as intellectual property or employment matters.

In addition, from time to time we may enter into negotiations for acquisitions that are not ultimately consummated. These negotiations could result in significant diversion of management time, as well as substantial out-of-pocket costs. If we were to proceed with one or more significant acquisitions in which the consideration included cash, we could be required to use a substantial portion of our available cash. To the extent we issue shares of capital stock or other rights to purchase capital stock, including options and warrants, the ownership of existing stockholders would be diluted. In addition, acquisitions may result in the incurrence of debt, contingent liabilities, large write-offs, or other unanticipated costs, events or circumstances, any of which could harm our operating results.

If we are not able to manage our growth effectively, or if our business does not grow as we expect, our operating results will suffer.

We have experienced significant revenue growth in a short period of time. For example, our revenue increased from $41.1 million for year ended December 31, 2009 to $101.0 million for the year ended December 31, 2012, and over this four-year period, we significantly expanded our operations and more than doubled the number of our employees from 129 as of December 31, 2008 to 343 as of December 31, 2012. Our rapid growth has placed, and will continue to place, a significant strain on our management systems, infrastructure and other resources. We plan to hire additional direct sales and marketing personnel domestically and internationally, acquire complementary businesses, technologies or assets, and increase our investment in research and development. Our future operating results depend to a large extent on our ability to successfully implement these plans and manage our anticipated expansion. To do so successfully we must, among other things:


•	manage our expenses in line with our operating plans and current business environment;


•	maintain and enhance our operational, financial and management controls, reporting systems and procedures;


•	integrate acquired businesses, technologies or assets;


•	manage operations in multiple locations and time zones; and


•	develop and deliver new solutions and enhancements to existing solutions efficiently and reliably.

We expect to incur costs associated with the investments made to support our growth before the anticipated benefits or the returns are realized, if at all. If we are unable to manage our growth effectively, we may not be able to take advantage of market opportunities or develop new solutions or enhancements to existing solutions. We may also fail to satisfy customer requirements, maintain quality, execute our business plan or respond to competitive pressures, which could result in lower revenue and a decline in the share price of our common stock.

The implementation of our new enterprise resource planning system could disrupt our business and adversely affect our financial results.

In the fourth quarter of 2012, we began the implementation of our solution for a new enterprise resource planning application, or ERP. We expect to go live with the new system in the second half of 2013. We may experience difficulties in implementing the ERP, and we may fail to obtain the risk mitigation benefits that the implementation is designed to produce. The implementation could also be disruptive to our operations, including the ability to timely ship and track product orders to our customers, project inventory requirements, manage our supply chain and otherwise adequately service our customers.

We generally recognize revenue from maintenance and support contracts over the contract term, and changes in sales may not be immediately reflected in our operating results.

We generally recognize revenue from our customer maintenance and support contracts ratably over the contract term, which is typically 12 months, in some cases subject to an early termination right. For 2012 and 2011, revenue from our maintenance and support contracts accounted for 26.0% and 27.0% of our revenue, respectively. A portion of the revenue we report in each quarter is derived from the recognition of deferred revenue relating to maintenance and support contracts entered into during previous quarters. Consequently, a decline in new or renewed maintenance and support by our customers in any one quarter may not be immediately reflected in our revenue for that quarter. Such a decline, however, will negatively affect our revenue in future quarters. Accordingly, the effect of significant downturns in sales and market acceptance of our services and potential changes in our rate of renewals may not be fully reflected in our operating results until future periods.

Table of Contents

The failure of our equipment lease customers to pay us under leasing agreements with them that we do not sell to third party lease finance companies could harm our revenue and operating results.

We recently began offering our badges and related hardware accessories to our customers through multi-year equipment lease agreements. For a sale, we recognize product-related revenue at the net present value of the lease payment stream once our obligations related to such sale have been met. We plan to sell the bulk of these leases, including the related accounts receivables, to third party lease finance companies on a non-recourse basis. We will have to retain unsold leases in-house, which will expose us to the creditworthiness of such equipment lease customers over the lease term. For the leases that we retain in-house, our ability to collect payments from a customer or to recognize revenue for the sale could be impaired if the customer fails to meet its obligations to us such as in the case of its bankruptcy filing or deterioration in its financial position, or has other creditworthiness issues, any of which could harm our revenue and operating results.

Our revenue and operating results have fluctuated, and are likely to continue to fluctuate, which may make our quarterly results difficult to predict, cause us to miss analyst expectations and cause the price of our common stock to decline.

Our operating results may be difficult to predict, even in the near term, and are likely to fluctuate as a result of a variety of factors, many of which are outside of our control. We have historically obtained substantially all of our revenue from the sale of our Voice Communication solution, which we anticipate will represent the most significant portion of our revenue for the foreseeable future, as we only began offering our Secure Messaging and Care Transition solutions in the last two years.

Comparisons of our revenue and operating results on a period-to-period basis may not be meaningful. You should not rely on our past results as an indication of our future performance. Each of the following factors, among others, could cause our operating results to fluctuate from quarter to quarter:


•	the financial health of our healthcare customers and budgetary constraints on their ability to upgrade their communications;


•	changes in the regulatory environment affecting our healthcare customers, including impediments to their ability to obtain reimbursement for their services;


•	our ability to expand our sales and marketing operations;


•	the procurement and deployment cycles of our healthcare customers and the length of our sales cycles;


•	variations in the amount of orders booked in a prior quarter but not delivered until later quarters;


•	our mix of solutions and pricing, including discounts by us or our competitors;


•	our ability to forecast demand and manage lead times for the manufacture of our solutions; and


•	our ability to develop and introduce new solutions and features to existing solutions that achieve market acceptance.

Our success depends upon our ability to attract, integrate and retain key personnel, and our failure to do so could harm our ability to grow our business.

Our success depends, in part, on the continuing services of our senior management and other key personnel, and our ability to continue to attract, integrate and retain highly skilled personnel, particularly in engineering, sales and marketing. Competition for highly skilled personnel is intense, particularly in the Silicon Valley where our headquarters are located. If we fail to attract, integrate and retain key personnel, our ability to grow our business could be harmed.

The members of our senior management and other key personnel are at-will employees, and may terminate their employment at any time without notice. If they terminate their employment, we may not be able to find qualified individuals to replace them on a timely basis or at all and our senior management may need to divert their attention from other aspects of our business. Former employees may also become employees of a competitor. We may also have to pay additional compensation to attract and retain key personnel. We also anticipate hiring additional engineering, marketing and sales, and services personnel to grow our business. Often, significant amounts of time and resources are required to train these personnel. We may incur significant costs to attract, integrate and retain them, and we may lose them to a competitor or another company before we realize the benefit of our investments in them.

We primarily compete in the rapidly evolving and competitive healthcare market, and if we fail to effectively respond to competitive pressures, our business and operating results could be harmed.

We believe that at this time the primary competition for our Voice Communication solution consists of traditional methods using wired phones, pagers and overhead intercoms. While we believe that our system is superior to these legacy methods, our solution requires a significant infrastructure investment by a hospital and many hospitals may not recognize the value of implementing our solution.

Table of Contents

Manufacturers and distributors of product categories such as cellular phones, pagers, mobile radios and in-building wireless telephones attempt to sell their products to hospitals as components of an overall communication system. Of these product categories, in-building wireless telephones represent the most significant competition for the sale of our solution. The market for in-building wireless phones is dominated by large horizontal communications companies such as Cisco Systems, Ascom and Polycom, which sold its Spectralink wireless phones business to a Sun Capital Partners’ affiliate in December 2012. In addition, while smartphones and tablets are not at present direct competitors, their proliferation may make them a de facto standard for hospital workflow, thereby making our solution less attractive to customers.

While we do not have a directly comparable competitor that provides a richly featured voice communication system for the healthcare market, we could face such competition in the future. Potential competitors in the healthcare or communications markets include large, multinational companies with significantly more resources to dedicate to product development and sales and marketing. These companies may have existing relationships within the hospital, which may enhance their ability to gain a foothold in our market. Customers may prefer to purchase a more highly integrated or bundled solution from a single provider or an existing supplier rather than a new supplier, regardless of performance or features. Accordingly, if we fail to effectively respond to competitive pressures, we could experience pricing pressure, reduced profit margins, higher sales and marketing expenses, lower revenue and the loss of market share, any of which would harm our business, operating results or financial condition.

Our international operations subject us, and may increasingly subject us in the future, to operational, financial, economic and political risks abroad.

Although we derive a relatively small portion of our revenue from customers outside the United States, we believe that non-U.S. customers could represent an increasing share of our revenue in the future. During 2012 and 2011, we obtained 10.7% and 7.3% of our revenue, respectively, from customers outside of the United States, including Canada, the United Kingdom, Australia, the Republic of Ireland and New Zealand. Accordingly, we are subject to risks and challenges that we would not otherwise face if we conducted our business solely in the United States, including:


•	challenges incorporating non-English speech recognition capabilities into our solutions as we expand into non-English speaking jurisdictions;


•	difficulties integrating our solutions with wireless infrastructures with which we do not have experience;


•	difficulties integrating local dialing plans and applicable PBX standards;


•	challenges associated with delivering support, training and documentation in several languages;


•	difficulties in staffing and managing personnel and resellers;


•	the need to comply with a wide variety of foreign laws and regulations, including increasingly stringent data privacy regulations, requirements for export controls for encryption technology, employment laws, changes in tax laws and tax audits by government agencies;


•	political and economic instability in, or foreign conflicts that involve or affect, the countries of our customers;


•	difficulties in collecting accounts receivable and longer accounts receivable payment cycles;


•	exposure to competitors who are more familiar with local markets;


•	limited or unfavorable intellectual property protection in some countries; and


•	currency exchange rate fluctuations, which could affect the price of our solutions relative to locally produced solutions.

Any of these factors could harm our existing international business, impair our ability to expand into international markets or harm our operating results.

Our Voice Communication solution is highly complex and may contain undetected software or hardware errors that could harm our reputation and operating results.

Our Voice Communication solution incorporates complex technology, is deployed in a variety of complex hospital environments and must interoperate with many different types of devices and hospital systems. While we test the components of our solutions for defects and errors prior to release, we or our customers may not discover a defect or error until after we have deployed our solution, integrated it into the hospital environment and our customer has commenced general use of the solution. For example, in 2005, a prior model of our wireless badge, the B1000, was affected by chipset compatibility issues with certain wireless access points at customer facilities, resulting in our exchanging a large percentage of deployed badges for new badges. We did this exchange at no cost to our customers, thereby incurring substantial costs. In addition, our solutions in some cases are integrated with hardware and software offered by “middleware” vendors in order to interoperate with nurse call systems, device alarms and other hospital systems. If we cannot successfully integrate our solution with these vendors as needed or if any hardware or software of these vendors contains any defect or error, then our solution may not perform as designed, or may exhibit a defect or error.

Table of Contents

Any defects or errors in, or which are attributed to, our solutions, could result in:


•	delayed market acceptance of our affected solutions;


•	loss of revenue or delay in revenue recognition;


•	loss of customers or inability to attract new customers;


•	diversion of engineering or other resources for remedying the defect or error;


•	damage to our brand and reputation;


•	increased service and warranty costs; and


•	legal actions by our customers and hospital patients, including product liability claims.

If any of these occur, our operating results and reputation could be harmed.

We face potential liability related to the privacy and security of personal information collected through our solutions.

In connection with our healthcare communications business, we handle and have access to personal health information subject in the United States to the Health Insurance Portability and Accountability Act of 1996, or HIPAA, the Health Information Technology for Economic and Clinical Health Act of 2009, or HITECH, regulations issued pursuant to these statutes, state privacy and security laws and regulations, and associated contractual obligations as a “business associate” of healthcare providers. These statutes, regulations and contractual obligations impose numerous requirements regarding the use and disclosure of personal health information with which we must comply. Our failure to accurately anticipate the application or interpretation of these statutes, regulations and contractual obligations as we develop our solutions, a failure by us to comply with their requirements (e.g., evolving encryption and security requirements) or an allegation that defects in our products have resulted in noncompliance by our customers could create material civil and/or criminal liability for us, resulting in adverse publicity and negatively affecting our business. In addition, the use and disclosure of personal health information is subject to regulation in other jurisdictions in which we do business or expect to do business in the future. Those jurisdictions may attempt to apply such laws extraterritorially or through treaties or other arrangements with U.S. governmental entities. We might unintentionally violate such laws, such laws may be modified and new laws may be enacted in the future which may increase the chance that we violate them. Any such developments, or developments stemming from enactment or modification of other laws, or the failure by us to comply with their requirements or to accurately anticipate the application or interpretation of these laws could create material liability to us, result in adverse publicity and negatively affect our business. For example, the European Union, or EU, adopted the Data Protection Directive, or DPD, imposing strict regulations and establishing a series of requirements regarding the storage of personally identifiable information on computers or recorded on other electronic media. This has been implemented by all EU member states through national laws. DPD provides for specific regulations requiring all non-EU countries doing business with EU member states to provide adequate data privacy protection when receiving personal data from any of the EU member states. Similarly, Canada’s Personal Information and Protection of Electronic Documents Act provides Canadian residents with privacy protections in regard to transactions with businesses and organizations in the private sector and sets out ground rules for how private sector organizations may collect, use and disclose personal information in the course of commercial activities. A finding that we have failed to comply with applicable laws and regulations regarding the collection, use and disclosure of personal information could create liability for us, result in adverse publicity and negatively affect our business.

Any legislation or regulation in the area of privacy and security of personal information could affect the way we operate our services and could harm our business. The costs of compliance with, and the other burdens imposed by, these and other laws or regulatory actions may prevent us from selling our solutions or increase the costs associated with selling our solutions, and may affect our ability to invest in or jointly develop solutions in the United States and in foreign jurisdictions. Further, we cannot assure you that our privacy and security policies and practices will be found sufficient to protect us from liability or adverse publicity relating to the privacy and security of personal information.

Developments in the healthcare industry and governing regulations could negatively affect our business.

Substantially all of our revenue is derived from customers in the healthcare industry, in particular, hospitals. The healthcare industry is highly regulated and is subject to changing political, legislative, regulatory and other influences. Developments generally affecting the healthcare industry, including new regulations or new interpretations of existing regulations, could adversely affect spending on information technology and capital equipment by reducing funding, changes in healthcare pricing or delivery or creating impediments for obtaining healthcare reimbursements, thereby causing our sales to decline and negatively impacting our business. For example, the profit margins of our hospital customers are modest and pending changes in reimbursement for healthcare costs may reduce the overall solvency of our customers or cause further deterioration in their financial or business condition.

Table of Contents

In March 2010, the United States enacted comprehensive healthcare reform legislation through the Patient Protection and Affordable Health Care for America Act and the Health Care and Education Reconciliation Act. By some estimates, the new law is expected to increase the number of Americans with health insurance coverage by approximately 32 million through individual and employer mandates, subsidies offered to lower income individuals with smaller employers and broadening of Medicaid eligibility, and to affect healthcare reimbursement levels for healthcare providers. We cannot predict with certainty what the ultimate effect of federal healthcare reform or any future legislation or regulation, or healthcare initiatives, if any, implemented at the state level, will have on us or our customers. For example, the federal healthcare reform imposed a 2.3% excise tax on medical devices beginning January 2013, to which our company will be subject if any of our communications solutions are classified as medical devices. The impact of the tax, coupled with reform-associated payment reductions to Medicare and Medicaid reimbursement, could harm our business, operating results and cash flows.

In addition, our customers’ expectations regarding pending or potential industry developments may also affect their budgeting processes and spending plans with respect to our communications solutions. The healthcare industry has changed significantly in recent years and we expect that significant changes will continue to occur. However, the timing and impact of developments in the healthcare industry are difficult to predict. We cannot assure you that the markets for our solutions will continue to exist at current levels or that we will have adequate technical, financial and marketing resources to react to changes in those markets.

Our use of open source and non-commercial software components could impose risks and limitations on our ability to commercialize our solutions.

Our solutions contain software modules licensed under open source and other types of non-commercial licenses, including the GNU Public License, the GNU Lesser Public License, the Apache License and others. We also may incorporate open source and other licensed software into our solutions in the future. Use and distribution of such software may entail greater risks than use of third-party commercial software, as licenses of these types generally do not provide warranties or other contractual protections regarding infringement claims or the quality of the code. Some of these licenses require the release of our proprietary source code to the public if we combine our proprietary software with open source software in certain manners. This could allow competitors to create similar products with lower development effort and time and ultimately result in a loss of sales for us.

The terms of many open source and other non-commercial licenses have not been judicially interpreted and there is a risk that such licenses could be construed in a manner that could impose unanticipated conditions or restrictions on our ability to commercialize our solutions. In such event, in order to continue offering our solutions, we could be required to seek licenses from alternative licensors, which may not be available on a commercially reasonable basis or at all, to re-engineer our solutions or to discontinue the sale of our solutions in the event we cannot obtain a license or re-engineer our solutions on a timely basis, any of which could harm our business and operating results. In addition, if an owner of licensed software were to allege that we had not complied with the conditions of the corresponding license agreement, we could incur significant legal costs defending ourselves against such allegations. In the event such claims were successful, we could be subject to significant damages, be required to disclose our source code, or be enjoined from the distribution of our solutions.

Claims of intellectual property infringement could harm our business.

Vigorous protection and pursuit of intellectual property rights has resulted in protracted and expensive litigation for many companies in our industry. Although claims of this kind have not materially affected our business to date, there can be no assurance of the absence of such claims in the future. Any claims or proceedings against us, whether meritorious or not, could be time consuming, result in costly litigation, require significant amounts of management time, result in the diversion of significant operational resources, or require us to enter into royalty or licensing agreements, any of which could harm our business and operating results.

Intellectual property lawsuits are subject to inherent uncertainties due to the complexity of the technical issues involved, and we cannot be certain that we will be successful in defending ourselves against intellectual property claims. In addition, we currently have a limited portfolio of issued patents compared to many other industry participants, and therefore may not be able to effectively utilize our intellectual property portfolio to assert defenses or counterclaims in response to patent infringement claims or litigation brought against us by third parties. Further, litigation may involve patent holding companies or other adverse patent owners who have no relevant products and against whom our potential patents may provide little or no deterrence.

Many potential litigants have the capability to dedicate substantially greater resources to enforce their intellectual property rights and to defend claims that may be brought against them. Furthermore, a successful claimant could secure a judgment that

Table of Contents

requires us to pay substantial damages or prevents us from distributing certain solutions or performing certain services. We might also be required to seek a license and pay royalties for the use of such intellectual property, which may not be available on commercially acceptable terms or at all. Alternatively, we may be required to develop non-infringing technology, which could require significant effort and expense and may ultimately not be successful.

If we are unable to protect our intellectual property rights, our competitive position could be harmed or we could be required to incur significant expenses to enforce our rights.

Our success depends, in part, on our ability to protect our proprietary technology. We protect our proprietary technology through patent, copyright, trade secret and trademark laws in the United States and similar laws in other countries. We also protect our proprietary technology through licensing agreements, nondisclosure agreements and other contractual provisions. These protections may not be available in all cases or may be inadequate to prevent our competitors from copying, reverse engineering or otherwise obtaining and using our technology, proprietary rights or solutions in an unauthorized manner. The laws of some foreign countries may not be as protective of intellectual property rights as those in the United States, and mechanisms for enforcement of intellectual property rights may be inadequate. In addition, third parties may seek to challenge, invalidate or circumvent our patents, trademarks, copyrights and trade secrets, or applications for any of the foregoing. Our competitors may independently develop technologies that are substantially equivalent, or superior, to our technology or design around our proprietary rights. In each case, our ability to compete could be significantly impaired.

To prevent unauthorized use of our intellectual property rights, it may be necessary to prosecute actions for infringement or misappropriation of our proprietary rights. Any such action could result in significant costs and diversion of our resources and management's attention, and there can be no assurance that we will be successful in such action. Furthermore, many of our current and potential competitors have the ability to dedicate substantially greater resources to enforce their intellectual property rights than us. Accordingly, despite our efforts, we may not be able to prevent third parties from infringing or misappropriating our intellectual property. While we plan to continue to protect our intellectual property with, among other things, patent protection, there can be no assurance that:


•	current or future U.S. or foreign patent applications will be approved;


•	our issued patents will protect our intellectual property and not be held invalid or unenforceable if challenged by third parties;


•	we will succeed in protecting our technology adequately in all key jurisdictions in which we or our competitors operate; or


•	others will not independently develop similar or competing products or methods or design around any patents that may be issued to us.

Our failure to obtain patents with claims of a scope necessary to cover our technology, or the invalidation of our patents, or our inability to protect any of our intellectual property, may weaken our competitive position and harm our business and operating results. We might be required to spend significant resources to monitor and protect our intellectual property rights. We may initiate claims or litigation against third parties for infringement of our proprietary rights or to establish the validity of our proprietary rights. Any litigation, whether or not it is resolved in our favor, could result in significant expense to us and divert the efforts of our technical and management personnel, which may harm our business, operating results and financial condition.

Our solutions could be subject to regulation by the U.S. Food and Drug Administration or similar foreign agencies, which could increase our operating costs.

We provide devices that may be, or may become, subject to regulation by the U.S. Food and Drug Administration, or FDA, and similar agencies in other countries, or the jurisdiction of these agencies could be expanded in the future to include our solutions. The FDA regulates certain products, including software-based products, as “medical devices” based, in part, on the intended use of the product and the risk the device poses to the patient should the device fail to perform properly. Although we have concluded that our wireless badge is a general-purpose communications device not subject to FDA regulation, the FDA could disagree with our conclusion, or changes in our solutions or the FDA’s evolving regulation could lead to FDA regulation of our solutions. Many other countries in which we sell or may sell our solutions could also have similar regulations applicable to our solutions, some of which may be subject to change or interpretation. We may incur substantial operating costs if we are required to register our solutions or components of our solutions as regulated medical devices under U.S. or foreign regulations, obtain premarket approval from the FDA or foreign regulatory agencies, and satisfy the extensive reporting requirements. In addition, failure to comply with these regulations could result in enforcement actions and monetary penalties.

Table of Contents

Product liability or other liability claims could cause us to incur significant costs, adversely affect the sales of our solutions and harm our reputation.

Our solutions are utilized by healthcare professionals and others in the course of providing patient care. It is possible that patients, family members, physicians, nurses or others may allege we are responsible for harm to patients or healthcare professionals due to defects in, the malfunction of, the characteristics of, or the operation of, our solutions. Any such allegations could harm our reputation and ability to sell our solutions.

Components of our solutions utilizing Wi-Fi also emit radio frequency, or RF, energy. RF emissions have been alleged, in connection with cellular phones, to have adverse health consequences. While these components of our solutions comply with guidelines applicable to such emissions, some may allege that these components of our solutions cause adverse health consequences or applicable guidelines may change making these components of our solutions non-compliant. Regulatory agencies in the United States and other countries in which we do or plan to do business may implement regulations concerning RF emissions standards. In addition, healthcare professionals have alleged and may allege in the future that magnets in our badges may emit electromagnetic radiation or otherwise interfere with implanted medical or other devices. Any such allegations or non-compliance, or any regulatory developments, including any changes affecting the transmission of radio signals, could negatively impact the sales of our solutions, require costly modifications to our solutions and harm our reputation.

Although our customer agreements contain terms and conditions, including disclaimers of liability, that are intended to reduce or eliminate our potential liability, we could be required to spend significant amounts of management time and resources to defend ourselves against product liability, tort, warranty or other claims. If any such claims were to prevail, we could be forced to pay damages, comply with injunctions or stop distributing our solutions. Even if potential claims do not result in liability to us, investigating and defending against these claims could be expensive and time consuming and could divert management's attention away from our business. We maintain general liability insurance coverage, including coverage for errors and omissions; however, this coverage may not be sufficient to cover large claims against us or otherwise continue to be available on acceptable terms. Further, the insurer could attempt to disclaim coverage as to any particular claim.

Our business is subject to the risks of earthquakes, fire, floods and other natural catastrophic events, and to interruption by man-made problems such as power disruptions or terrorism.

Our corporate headquarters are located in the San Francisco Bay Area, a region known for seismic activity, and many critical components of our solutions are sourced in Asia and Mexico, regions known to suffer natural disasters. A significant natural disaster, such as an earthquake, fire or a flood, occurring at our headquarters, our other facilities or where our contract manufacturer or its suppliers are located, could harm our business, operating results and financial condition. In addition, acts of terrorism could cause disruptions in our business, the businesses of our customers and suppliers, or the economy as a whole. We also rely on information technology systems to communicate among our workforce located worldwide, and in particular, our senior management, general and administrative, and research and development activities that are coordinated with our corporate headquarters in the San Francisco Bay Area. Any disruption to our internal communications, whether caused by a natural disaster or by man-made problems, such as power disruptions, in the San Francisco Bay Area, Asia or Mexico could delay our research and development efforts, cause delays or cancellations of customer orders or delay deployment of our solutions, which could harm our business, operating results and financial condition.

We may require additional capital to support our business growth, and such capital may not be available.

We intend to continue to make investments to support business growth and may require additional funds to respond to business challenges, which include the need to develop new solutions or enhance existing solutions, enhance our operating infrastructure, expand our sales and marketing capabilities, expand into non-healthcare markets, and acquire complementary businesses, technologies or assets. Accordingly, we may need to engage in equity or debt financing to secure funds. Equity and debt financing, however, might not be available when needed or, if available, might not be available on terms satisfactory to us. If we raise additional funds through equity financing, our stockholders may experience dilution. Debt financing, if available, may involve covenants restricting our operations or our ability to incur additional debt. If we are unable to obtain adequate financing or financing on terms satisfactory to us, our ability to continue to support our business growth and to respond to business challenges could be significantly limited as we may have to delay, reduce the scope of or eliminate some or all of our initiatives, which could harm our operating results.

As an “emerging growth company” under the JOBS Act, we are permitted to, and may, rely on exemptions from certain disclosure and governance requirements.

As an “emerging growth company” under the Jumpstart Our Business Startups Act, or JOBS Act, we are permitted to, and may, rely on exemptions from certain disclosure and governance requirements. For example, for so long as we are an emerging growth company, which can last, at most, until the first fiscal year following the fifth anniversary of our initial public offering, we will not be required to:


•	have our independent registered public accounting firm report on our internal control over financial reporting pursuant to Section 404(b) of the Sarbanes-Oxley Act;


•	comply with any requirement that may be adopted by the Public Company Accounting Oversight Board regarding mandatory audit firm rotation or a supplement to the auditor's report providing additional information about the audit and the financial statements;


•	provide the “compensation discussion and analysis” and certain compensation tables for our named executive officers in our Form 10-K or annual proxy statement; and


•	submit certain executive compensation matters to stockholder advisory votes, such as “say on pay” and “say on frequency.”

We could be an emerging growth company for up to five years, although, if the market value of our common stock that is held by non-affiliates exceeds $700 million as of June 30 of any year starting with June 30, 2013, we could cease to be an “emerging growth company” as of the following December 31. Thereafter, as of each fiscal year end, our independent registered public accounting firm will be required to evaluate and report on our internal control over financial reporting under Section 404(b) of the Sarbanes-Oxley Act. While management has established plans to accommodate the additional assessment and attestation procedures and related costs of Section 404(b) compliance, we may incur additional costs or require additional management time to comply with Section 404(b) in a timely manner. To the extent we find a material weakness or other deficiency in our internal control over financial reporting, the accuracy and timeliness of our financial reporting may be adversely affected.

If we do not maintain effective internal control over financial reporting or disclosure controls and procedures in the future, the accuracy and timeliness of our financial reporting may be adversely affected.

The Sarbanes-Oxley Act requires, among other things, that we assess the effectiveness of our internal control over financial reporting annually and disclosure controls and procedures quarterly. In particular, beginning with the year ending on December 31, 2013, we must obtain reasonable assurance of our internal control over financial reporting to allow management to report on the effectiveness of our internal control over financial reporting as required by Section 404 of the Sarbanes-Oxley Act. If a material weakness in our internal control over financial reporting is identified in the future, we are not able to comply with the requirements of Section 404 in a timely manner or we do not maintain effective controls, our reported financial results could be materially misstated or could be restated, we could receive an adverse opinion regarding our controls from our independent registered public accounting firm (once such opinion is required under the Sarbanes-Oxley Act), we could be subject to investigations or sanctions by regulatory authorities, which would require additional financial and management resources, and the market price of our stock could decline.

We will continue to incur increased costs as a result of operating as a public company and our management will have to devote substantial time to public company compliance obligations.

As a public company, we will continue to incur substantial legal, accounting and other expenses that we did not incur as a private company. We will continue to incur substantial expenses even though we as an “emerging growth company” may rely upon the disclosure and governance exemptions under the JOBS Act. The Sarbanes-Oxley Act of 2002, or Sarbanes-Oxley Act, as well as rules subsequently implemented by the SEC and our stock exchange, impose various requirements on public companies, including changes in corporate governance practices. Our management and other personnel will need to devote a substantial amount of time to these compliance requirements and any new requirements that the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 may impose on public companies. Moreover, these rules and regulations, along with compliance with accounting principles and regulatory interpretations of such principles, as amended by the JOBS Act, have increased and will continue to increase our legal, accounting and financial compliance costs and have made and will continue to make some activities more time-consuming and costly. For example, we expect these rules and regulations to make it more difficult and more expensive for us to obtain director and officer liability insurance, and we may be required to accept reduced policy limits and coverage or incur substantial costs to maintain the same or similar coverage.

Compliance with the SEC's new rule for disclosures on sourcing of "conflict minerals" will likely be time consuming and potentially costly and could adversely affect our reputation.

Table of Contents

Under the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, the SEC has adopted a new rule that applies to companies that use certain minerals and metals, known as conflict minerals, in their products, including certain products manufactured for them by third parties. The new rule will require companies that use conflict minerals in the production of their products to conduct diligence as to whether or not such minerals originate from the Democratic Republic of Congo and adjoining countries and to file certain information with the SEC about the use of these minerals. We will incur additional costs to comply with the due diligence and disclosure requirements. In addition, depending upon our findings, or our inability to make reliable findings, about the source of any conflict minerals that we use, our reputation could be harmed. While the first report is not due until 2014, we will need to incur costs in preparation for this reporting in 2013. Certain industry organizations have filed a petition challenging the adoption of the new rule by the SEC, but we are unable to predict the impact of this challenge on the applicability of the new rule.

Risks related to our common stock

The market price of our common stock may be volatile, and your investment in our stock could suffer a decline in value.

There has been significant volatility in the market price and trading volume of equity securities, which is often unrelated or disproportionate to the financial performance of the companies issuing the securities. These broad market fluctuations may negatively affect the market price of our common stock. The market price of our common stock could fluctuate significantly in response to the factors described in this “Risk Factors” section and elsewhere in this Form 10-K and other factors, many of which are beyond our control, including:


•	actual or anticipated variation in anticipated operating results of us or our competitors;


•	the financial projections we may provide to the public, any changes in these projections or our failure to meet these projections;


•	announcements by us or our competitors of new solutions, new or terminated significant contracts, commercial relationships or capital commitments;


•	failure of securities analysts to maintain coverage of us, changes in financial estimates by any securities analysts who follow our company, or our failure to meet these estimates or the expectations of investors;


•	developments or disputes concerning our intellectual property or other proprietary rights;


•	commencement of, or our involvement in, litigation;


•	announced or completed acquisitions of businesses, technologies or assets by us or our competitor;


•	changes in operating performance and stock market valuations of other technology companies generally, or those in our industry in particular;


•	price and volume fluctuations attributable to inconsistent trading volume levels of our common stock;


•	our public float relative to the total number of shares of our common stock that are issued and outstanding;


•	price and volume fluctuations in the overall stock market, including as a result of trends in the economy as a whole;


•	rumors and market speculation involving us or other companies in our industry;


•	any major change in our management;


•	unfavorable economic conditions and slow or negative growth of our markets; and


•	other events or factors, including those resulting from war or incidents of terrorism.

In addition, in the past, following periods of volatility in the overall market and the market price of a particular company’s securities, securities class action litigation has often been instituted against these companies. This litigation, if instituted against us, could result in substantial costs and a diversion of our management's attention and resources.

If securities or industry analysts issue an adverse or misleading opinion regarding our stock or do not publish research or reports about our business, our stock price could decline.

The trading market for our common stock depends in part on the research and reports that securities or industry analysts publish about us and our business. We do not control these analysts or the content and opinions included in their reports. The price of our common stock could decline if one or more analysts downgrade our common stock or if those analysts issue other unfavorable commentary or cease publishing reports about us or our business. If one or more analysts cease coverage of our company or fail to regularly publish reports about our company, we could lose visibility in the financial market, which in turn could cause our stock price to decline. Further, securities or industry analysts may elect not to provide research coverage of our common stock and such lack of research coverage may adversely affect the market price of our common stock.

The concentration of our capital stock ownership with insiders will likely limit your ability to influence corporate matters.

Our executive officers, directors, current 5% or greater stockholders and entities affiliated with any of them together beneficially own approximately 42% of our common stock outstanding as of December 31, 2012. These stockholders, if they

Table of Contents

act together, will have significant influence over all matters requiring stockholder approval, including the election of directors and approval of significant corporate transactions, and may take actions that may not be in the best interests of our other stockholders. This concentration of ownership could also limit stockholders’ ability to influence corporate matters. Accordingly, corporate actions might be taken even if other stockholders, including you, oppose them, or may not be taken even if other stockholders view them as in the best interests of our stockholders. This concentration of ownership may have the effect of delaying or preventing a change of control of our company, may make the approval of certain transactions difficult or impossible without the support of these stockholders and might adversely affect the market price of our common stock.

Our management has broad discretion over the use of proceeds from our public offerings and might not apply the proceeds of our public offerings in ways that increase the value of your investment in our company.

Our management has broad discretion to use the net proceeds to us from our initial public offering and our secondary public offering, and you are relying on the judgment of our management regarding the application of these proceeds, without the opportunity to assess whether the proceeds are being used appropriately. The failure of our management to apply the $70.5 million net proceeds of our initial public offering and the $36.0 million net proceeds from our secondary public offering effectively could harm our business, financial condition and operating results, and may not increase the value of your investment in our company. Largely as a result of these public offerings, we had $127.5 million invested in cash, cash equivalents, and short-term investments at December 31, 2012. We have not allocated these net proceeds for specific purposes other than allocating a portion of the proceeds from our initial public offering to the repayment in full of outstanding borrowings under our credit facility, which we repaid in April 2012. We intend to use the net proceeds from our public offerings for general corporate and working capital purposes. We may also use a portion of the net proceeds to acquire or invest in complementary businesses, technologies or assets, but at this time, we have no current understandings, agreements or commitments to do so. Our management might not be able to yield a significant return or any return on any investment of these net proceeds.

Our stock price could decline due to the substantial number of outstanding shares of our common stock that are available for sale on the public market.

All of our outstanding shares recently became freely tradable without restrictions or further registration under the federal securities laws, except for shares held by directors, executive officers and other affiliates which are subject to volume limitations under Rule 144 of the Securities Act of 1933 and various vesting agreements. If the holders of the shares that were previously subject to transfer restrictions sell, or indicate an intention to sell, substantial amounts of our common stock could be available for sale in the public market, and the trading price of our common stock could decline. Additional shares subject to outstanding warrants and shares subject to outstanding options and reserved for future issuance under our stock option and purchase plans could also be available for sale in the public market to the extent permitted by the provisions of various vesting agreements and Rules 144 and 701 under the Securities Act.

We have never paid cash dividends on our capital stock, and we do not anticipate paying any dividends in the foreseeable future.

We have never paid cash dividends on any of our capital stock and currently intend to retain our future earnings to fund the development and growth of our business. As a result, capital appreciation, if any, of our common stock will be the sole source of gain for the foreseeable future.

Our charter documents and Delaware law could discourage, delay or prevent a change of control of our company or change in our management that stockholders consider favorable and cause our stock price to decline.

Certain provisions of our restated certificate of incorporation and restated bylaws and Delaware law could discourage, delay or prevent a change of control of our company or change in our management that the stockholders of our company consider favorable. These provisions:


•	authorize the issuance of “blank check” preferred stock that our board of directors could issue to increase the number of outstanding shares and to discourage a takeover attempt;


•	prohibit stockholder action by written consent, requiring all stockholder actions to be taken at a meeting of stockholders;


•	establish advance notice procedures for nominating candidates to our board of directors or proposing matters that can be acted upon by stockholders at stockholder meetings;


•	limit the ability of our stockholders to call special meetings of stockholders;


•	prohibit stockholders from cumulating their votes for the election of directors;


•	permit newly created directorships resulting from an increase in the authorized number of directors or vacancies on our board of directors to be filled only by majority vote of our remaining directors, even if less than a quorum is then in office;


•	provide that our board of directors is expressly authorized to make, alter or repeal our bylaws;

Table of Contents


•	establish a classified board of directors so that not all members of our board are elected at one time;


•	provide that our directors may be removed only for “cause” and only with the approval of the holders of at least 66 2/3rds percent of our outstanding stock; and


•	require super-majority voting to amend certain provisions in our certificate of incorporation and bylaws.

Section 203 of the Delaware General Corporation Law may also discourage, delay or prevent a change of control of our company.

Business overview

We are a provider of mobile communication solutions focused on addressing critical communication challenges facing hospitals today. We help our customers improve patient safety and satisfaction, and increase hospital efficiency and productivity through our Voice Communication, Secure Messaging and Care Transition solutions. Our Voice Communication solution, which includes a lightweight, wearable, voice-controlled communication badge and a software platform, enables users to connect instantly with other hospital staff simply by saying the name, function or group name of the desired recipient. Our Secure Messaging solution securely delivers text messages and alerts directly to and from smartphones, replacing legacy pagers. Our Care Transition solution is a hosted voice and text based software application that captures, manages and monitors patient information when responsibility for the patient is transferred or “handed-off” from one caregiver to another, or when the patient is discharged from the hospital.

At the core of our Voice Communication solution is a patent-protected software platform that we introduced in 2002. We have significantly enhanced and added features and functionality to this solution through ongoing development based on frequent interactions with our customers. Our software platform is built upon a scalable architecture and recognizes more than 100 voice commands. Users can instantly communicate with others using the Vocera communication badge, or through Vocera Connect client applications available for iPhone and Android smartphones, as well as Cisco wireless IP phones and other mobile devices. Our Voice Communication solution can also be integrated with nurse call and other clinical systems to immediately and efficiently alert hospital workers to patient needs. We have shipped over 500,000 communication badges to our customers.

We outsource the manufacturing of our products. Our outsourced manufacturing model allows us to scale our business without the significant capital investment and on-going expenses required to establish and maintain manufacturing operations. We work closely with our contract manufacturer, SMTC Corporation, and key suppliers to manage the procurement, quality and cost of components. We seek to maintain an optimal level of finished goods inventory to meet our forecast sales and unanticipated shifts in sales volume and mix.

We primarily sell products and maintenance services directly to end users. To date, substantially all of our revenue has been derived from sales of our Voice Communication solution, including product maintenance and related services. Revenue grew 27.0% to $101.0 million in 2012 from $79.5 million in 2011, and our 2011 revenue grew 40.0% from $56.8 million in 2010. For the year ended December 31, 2012 we recorded net income of $2.9 million. For the year ended December 31, 2011, we recorded a net loss of $2.5 million, which included $1.0 million of additional outside service costs as we prepared to become a public company.

Our diverse customer base ranges from large hospital systems to small local hospitals, as well as other healthcare facilities and customers in non-healthcare markets. We are not reliant on any one or group of customers. For 2012, our largest end customer represented only 2.7% of revenue. While we have international customers in other English speaking countries such as Canada, the United Kingdom and Australia, most of our customers are located in the United States. International customers represented 10.7% and 7.3% of our revenue in 2012 and in 2011, respectively. We are developing plans to expand our presence in other English speaking markets and enter non-English speaking markets.

Our growth in 2012 was primarily due to increased product sales of our Voice Communication solution, and, to a lesser extent, to an increase in services sales. We had balanced growth in product sales in 2012, with increases in sales to new customers and expanded deployments by existing customers, as well as sales of replacement badges due, in part, to favorable reception of our new B3000 badges. We believe that we have the ability to continue to grow in each of these areas in 2013. In addition, we are continuing to invest to accelerate the development of new products for our healthcare and targeted non-healthcare markets. In the fourth quarter of 2012 and continuing into the first quarter of 2013, we expanded and, we believe, upgraded our sales organization with the addition of new sales personnel and bifurcating sales roles between obtaining new customers and managing the installed customer base. In recent months, we also entered into sales contracts with four national health systems. A potential challenge in 2013 are sales to US government customers, which have experienced a slowdown and deferral of

Table of Contents

orders due to the ongoing effects of and uncertainty around sequestration and debt ceiling issues. We believe that our business to US government customers will continue to be less visible and predictable in 2013 as we experienced in the third and fourth quarters of 2012.

Acquisitions

During the last four months of 2010, we completed four acquisitions, for total purchase consideration of $10.0 million. Assets acquired and liabilities assumed were recorded at their estimated fair values as of the respective acquisition date. We recorded $4.4 million as identifiable intangible assets and $5.6 million as goodwill. We also incurred $1.0 million in acquisition related expenses, which was recorded in general and administrative expense. These acquisitions did not contribute significantly to our revenue in 2010.

The acquisitions of Integrated Voice Systems and of the OptiVox product line enhanced our product offerings by incorporating solutions designed to streamline patient hand-offs, enabling caregivers to capture and transfer important information in a secure, manageable, web-enabled manner. The acquisition of Wallace Wireless provided us with smartphone messaging solutions enabling the secure delivery of text messages, alerts and other information directly to and from smartphones, complementing our Voice Communication solution. The acquisition of DS Consulting Associates, d/b/a ExperiaHealth, enabled us to provide patient experience consulting services to help hospitals improve patient experience and safety.

Components of operating results

Revenue. We generate revenue from the sale of products and services. As discussed further in the section titled “Critical accounting policies and estimates—Revenue recognition and deferred revenue” below, revenue is recognized when persuasive evidence of an arrangement exists, delivery has occurred, the price is fixed or determinable and collection is reasonably assured.

Revenue is comprised of the following:

•

Product. Our solutions include both hardware and software. We refer to hardware revenue as device revenue, which includes revenue from sales of our communication badges, badge accessories, including batteries, battery chargers, lanyards, clips and other ancillary badge components, and our Vocera smartphone. Software revenue is derived primarily from the sale of perpetual licenses to our Voice Communication solution. We derive additional software revenue from the sale of term licenses, which can be renewed on a subscription basis. Product revenue is generally recognized upon shipment of hardware and perpetual licenses and, in the case of term licenses, ratably over the applicable term.

•

Service. We receive service revenue from sales of software maintenance, extended warranties and professional services. Software maintenance is typically invoiced annually in advance, recorded as deferred revenue, and recognized as revenue ratably over the service period. Our professional services revenue is based on both time and materials, and fixed price contracts, and is recognized as the services are provided. Extended warranties are invoiced in advance, recorded as deferred revenue, and recognized ratably over the extended warranty period.

Cost of revenue. Cost of revenue is comprised of the following:

•

Cost of product. Cost of product is comprised primarily of materials costs, software license costs, warranty, and manufacturing overhead for test engineering, material requirements planning and our shipping and receiving functions. Cost of product also includes facility costs and write-offs for excess and obsolete inventory, as well as depreciation and amortization expenses. As we introduce new products, we expect material costs will increase as a percent of revenue for a period of time.

•

Cost of service. Cost of service is comprised primarily of employee wages, benefits and related personnel expenses of our technical support team, our professional consulting personnel and our training teams. Cost of service also includes facility and information technology costs. We expect our cost of service will increase as we continue to invest in support services to meet the needs of our customer base.

Operating expenses. Operating expenses are comprised of the following:

•

Research and development. Research and development expenses consist primarily of employee wages, benefits and related personnel expenses, hardware materials, and consultant fees and expenses related to the design, development, testing and enhancements of our solutions. We intend to continue to invest in improving the functionality of our solutions and the development of new solutions. As a result, we expect research and development expense to increase for the foreseeable future.


•	Sales and marketing. Sales and marketing expenses consist primarily of employee wages, benefits and related personnel expenses, as well as trade shows, marketing and public relations programs and advertising. Sales commissions are earned

Table of Contents

when an order is received from a customer, and as a result, in some cases these commissions are expensed in an earlier period than the period in which the related revenue is recognized. Historically, our bookings have tended to peak in the fourth quarter of each year driving higher sales commissions, and to be lowest in the first quarter. We intend to continue to expand our direct sales force for the foreseeable future and, accordingly, expect sales and marketing expenses to increase.

•

General and administrative. General and administrative expenses consist primarily of employee wages, benefits and related personnel expenses, consulting, audit fees, legal fees and other general corporate expenses. We expect general and administrative expense to increase for the foreseeable future due to the significant costs we expect to incur as we continue to build and maintain the infrastructure necessary to comply with the regulatory requirements of being a public company and as we add personnel to support our growth.

Interest income, interest expense and other income (expense), net.


•	Interest income. Interest income consists primarily of interest income earned on our cash, cash equivalent and short-term investment balances. Our interest income will vary each reporting period depending on our average cash, cash equivalent and short-term investment balances during the period and market interest rates.


•	Interest expense. Interest expense includes interest expense related to debt and financing obligations resulting from our credit facility and security agreement, which was paid off in full on April 3, 2012. We expect interest expense to fluctuate in the future with changes in our borrowings.

•

Other income (expense), net. Other income (expense), net consists primarily of income from a stipend for market research regarding the industry in which our company operates that we provided to a market research firm, and the change in the fair value of our convertible preferred stock warrants. Our convertible preferred stock warrants were classified as liabilities and, as such, were marked-to-market at each balance sheet date with the corresponding gain or loss from the adjustment recorded as other income (expense), net. Upon the consummation of our initial public offering, on April 2, 2012, these warrants converted into warrants to purchase common stock and are no longer marked-to-market. Other income (expense), net also includes any foreign exchange gains and losses.

Provision for income taxes. We are subject to income taxes in the countries where we sell our solutions. We anticipate that in the future as we expand our sale of solutions to customers outside the United States, we will become subject to taxation based on the foreign statutory rates in the countries where these sales took place and our effective tax rate could fluctuate accordingly. Currently, each of our international subsidiaries is operating under cost plus agreements where the U.S. parent company reimburses the international subsidiary for its costs plus an arm's length profit.

Income taxes are computed using the asset and liability method, under which deferred tax assets and liabilities are determined based on the difference between the financial statement and tax bases of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to affect taxable income. Valuation allowances have been established to reduce deferred tax assets to the amount reasonably expected to be realized. Changes in valuation allowances are reflected as component of provision for income taxes.

At December 31, 2012, we had a valuation allowance against net deferred tax assets of $21.5 million. While we are encouraged by the pretax profit earned in 2012 and by the favorable trend of our financial results, management believes it is appropriate to obtain confirmatory evidence that the improvement in our results of operations is sustainable, and that realization of at least some of the deferred income tax assets is more likely than not, before reversing a portion of the valuation allowance to earnings.

We intend to review on a quarterly basis our conclusions about the appropriate amount of its deferred income tax asset valuation allowance. If we continue to generate profits in 2013 and beyond, it is likely that the US valuation allowance position will be reversed in the foreseeable future. We expect a significant benefit to be recorded in the period the valuation allowance reversal is recorded and a significantly higher effective tax rate in periods following the valuation allowance reversal.

Total revenue increased $21.5 million, or 27.0%, from 2011 to 2012.

Product revenue increased $14.7 million, or 29.2% in 2012. Device revenue increased $10.6 million, or 28.7%, and software revenue increased $4.1 million, or 30.7%. The 2012 increase in device revenue, which related entirely to our Voice Communication solution, was driven by an increase in unit sales of badges and related accessories from new customers making initial purchases, existing customers expanding deployments within their facilities to new departments and users, and customers replacing badges. The list prices for our products did not change substantially in 2012. The 2012 increase in software revenue was comprised of $3.5 million from an increase in the sale of licenses of our Voice Communication solution to new and existing customers and $0.6 million from other software revenue.

Table of Contents

Service revenue increased $6.7 million, or 23.1% in 2012. Software maintenance and support revenue increased $4.8 million, or 22.4%, and professional services and training revenue increased $2.0 million, or 25.2%. The 2012 increase in software maintenance and support revenue was primarily a result of a larger customer base but also included $1.0 million from extended warranty contracts and $0.3 million from other software services. The 2012 increase in professional services and training revenue included $0.9 million as a result of an increase in the number of new deployments and expansions of our Voice Communication solution. The remaining increase in professional services and training revenue of $0.9 million was from other service offerings.

Total gross margin	63.7			60.4			3.3

Cost of product revenue increased $4.1 million, or 23.4%, from 2011 to 2012. This increase was primarily due to the higher product revenue, offset by decreases due to lower per unit material and manufacturing costs as a result of increased unit volume and lower warranty expenses in 2012 due to lower return rates on our B3000 badge compared to the B2000 badge and to lower cost estimates for refurbishment and replacement alternatives. In 2011, we recorded a $0.6 million provision for excess inventory of the Vocera Wi-Fi smartphone due to quantities-on-hand exceeding forecast demand. Excluding the excess inventory charge, product gross margins in 2011 would have been only 0.4% lower than those realized in 2012.

Cost of service revenue increased $1.0 million, or 7.3%, from 2011 to 2012. This increase was primarily due to a $0.9 million increase in employee wages and other personnel costs in our technical support and professional services organizations to support growth in customer deployments and in our installed base. Headcount in our services organization increased from 71 employees at December 31, 2011 to 80 employees at December 31, 2012.

Research and development expense. Research and development expense increased $2.3 million, or 24.5%, from 2011 to 2012. This increase was primarily due to an increase in employee wages and other personnel related costs of $1.6 million, a $0.3 million increase in stock compensation expenses and $0.4 million increase in other support costs. Headcount in our research and development organization increased from 50 employees at December 31, 2011 to 59 employees at December 31, 2012.

Sales and marketing expense. Sales and marketing expense increased $5.3 million, or 18.8%, from 2011 to 2012. This increase was primarily due to a $4.1 million increase in employee wages and other personnel costs to support corporate marketing and sales efforts, a $1.0 million increase in stock compensation expenses, $0.4 million increase in travel, $0.5 million increase in other support, offset by a $0.7 million decrease in brand and product launch expenses associated with the B3000 release in 2011. Headcount in our sales and marketing organization increased from 115 employees at December 31, 2011 to 136 employees at December 31, 2012. In particular, we expanded our sales force in the fourth quarter of 2012 and expect sales and marketing expense to increase as this expanded sales organization is in place for the full year.

General and administrative expense. General and administrative expense increased $3.1 million, or 27.2%, from 2011 to 2012. This increase was due to a $2.9 million increase in employee wages and other personnel costs, a $0.6 million increase in stock compensation expense, a $0.4 million increase in outside services costs as we prepared to become a public company, partially offset by a $0.8 million decrease in other support costs. Headcount in our general and administrative organization increased from 35 employees at December 31, 2011 to 44 employees at December 31, 2012.

Interest income. Interest income increased $0.2 million from 2011 to 2012 due to higher cash balances from the proceeds of our initial public offering and follow-on offering completed in 2012.

Interest expense. Interest expense decreased $0.2 million from 2011 to 2012 as we paid all outstanding debt upon completion of our initial public offering.

Other income (expense), net. The $0.4 million increase in other expense from 2011 to 2012 is due to a $0.7 million increase in fair market value of the convertible preferred stock warrants offset by a $0.2 million increase in other income and a $0.1 million decrease in foreign exchange losses.

Provision for income taxes. The $0.6 million provision on $3.5 million of pretax income in 2012 represented an effective tax rate of 17.8%. For 2011, the provision of $0.3 million on the consolidated pretax loss of $2.2 million represented a negative effective rate of 13.0%. The lower-than-normal 17.8% rate for 2012 was due primarily to the impact of the utilization of the valuation allowance on net deferred tax assets, together with permanent tax adjustments for stock options. The negative 13.0% rate for 2011 is due primarily to the increase in the valuation allowance on net deferred tax assets, together with tax liabilities in the foreign subsidiaries.

Total revenue increased $22.7 million, or 40.0%, from 2010 to 2011.

Product revenue increased $14.8 million, or 41.7% in 2011. Device revenue increased $10.4 million, or 38.8%, and software revenue increased $4.4 million, or 50.6%. The 2011 increase in device revenue, which related entirely to our Voice Communication solution, was driven by an increase in unit sales of badges and related accessories from new customers making initial purchases, existing customers expanding deployments within their facilities to new departments and users, and customers replacing badges. The list prices for our products did not change substantially in 2011. The 2011 increase in software revenue was comprised of $2.4 million from acquisitions completed in the second half of 2010 and $2.0 million from an increase in the sale of licenses of our Voice Communication solution to new and existing customers.

Table of Contents

Service revenue increased $7.9 million, or 37.1% in 2011. Software maintenance and support revenue increased $4.0 million, or 22.9%, and professional services and training revenue increased $3.9 million, or 101.6%. The 2011 increase in software maintenance and support revenue was primarily a result of a larger customer base but also included $0.4 million from acquisitions completed in the second half of 2010. The 2011 increase in professional services and training revenue included $2.7 million as a result of an increase in the number of new deployments and expansions of our Voice Communication solution. The remaining increase in professional services and training revenue of $1.2 million was from acquisitions completed in the second half of 2010. Prior to our transition to a direct sales strategy, our reseller channel primarily provided the professional services associated with new deployments and expansions. We substantially expanded the capacity of our professional services organization from 32 professionals at December 31, 2010 to 40 professionals at December 31, 2011. A portion of the professional services and training revenue recorded in 2011 was due to the completion of services that we were not able to complete in 2010 due to the limited size of our staff.

Total gross margin	60.4			62.7			(2.3		)

Cost of product revenue increased $5.2 million, or 42.9%, from 2010 to 2011. This increase was primarily due to the higher product revenue. We recorded a provision for excess inventory of the Vocera Wi-Fi smartphone in 2011 due to quantities-on-hand exceeding forecast demand. This resulted in a charge of $0.6 million. Excluding the excess inventory charge, product gross margins would have improved in 2011 due to lower per unit material and manufacturing costs, largely due to increased unit volume.

Cost of service revenue increased $5.1 million, or 56.8%, from 2010 to 2011. This increase was primarily due to a $2.7 million increase in employee wages and other personnel costs in our professional services organization to support growth in customer deployments. Cost of service revenue also increased $1.3 million as a result of personnel costs and other expenses associated with the 2010 acquisitions. Headcount in our services organization increased from 60 employees at December 31, 2010 to 71 employees at December 31, 2011.

Research and development expense. Research and development expense increased $2.6 million, or 39.4%, from 2010 to 2011. This increase was primarily due to personnel costs and other expenses associated with the 2010 acquisitions of $1.5 million, an increase in employee wages and other personnel costs of $0.7 million, and a $0.4 million increase in outside service and development costs. Headcount in our research and development organization increased from 42 employees at December 31, 2010 to 50 employees at December 31, 2011.

Table of Contents

Sales and marketing expense. Sales and marketing expense increased $7.2 million, or 34.4%, from 2010 to 2011. This increase was primarily due to a $3.2 million increase in employee wages and other personnel costs to support corporate marketing and sales efforts, a $1.3 million increase in expenses related to brand and product launch expenses, and a $0.5 million increase in equipment and supplies related expenses. Sales and marketing expenses also increased $2.2 million as a result of personnel costs and other expenses associated with the 2010 acquisitions. Headcount in our sales and marketing organization increased from 95 employees at December 31, 2010 to 115 employees at December 31, 2011.

General and administrative expense. General and administrative expense increased $4.6 million, or 68.3%, from 2010 to 2011. This increase was due to a $2.5 million increase in employee wages and other personnel costs, a $0.8 million increase in stock compensation expense, and a $0.7 million increase in outside services costs as we prepared to become a public company. General and administrative expenses also increased $0.4 million as a result of personnel costs and other expenses due to the 2010 acquisitions. Headcount in our general and administrative organization increased from 24 employees at December 31, 2010 to 35 employees at December 31, 2011.

Interest income. Interest income decreased slightly from 2010 to 2011 due to a lower return on cash balances.

Interest expense. Interest expense increased $0.3 million from 2010 to 2011 due to increased borrowings.

Other income (expense), net. The $0.7 million increase in other expense from 2010 to 2011 is due primarily to the change in fair market value of the convertible preferred stock warrants.

(Provision for) benefit from income taxes. The 2011 tax provision of $0.3 million on the consolidated pretax loss of $2.2 million represented a negative effective rate of 13.0%, while in 2010, the $0.4 million benefit for income taxes in 2010 on net income of $0.8 million represented a negative effective rate of 43.5%. Contributors to a tax benefit recorded against positive income in 2010 included benefits realized in 2010 related to the release of the valuation allowance on deferred tax assets used to offset deferred tax liabilities that we recognized as a result of the acquisitions made in 2010. The negative 2011 rate reflected the same factors, together with liabilities in the foreign subsidiaries.

As of December 31, 2012, we had cash and cash equivalents and short-term investments of $127.5 million and no debt.

On April 2, 2012, we completed our initial public offering in which we and existing stockholders sold 6,727,500 shares of common stock at $16.00 per share, before underwriting discounts and commissions. We sold 5,000,000 shares and existing stockholders sold an aggregate of 1,727,500 shares, including 877,500 shares as a result of the underwriters’ exercise of their over-allotment option. We recorded net proceeds of $70.5 million from the initial public offering, after subtraction of

Table of Contents

underwriters’ discounts and commissions, and offering expenses incurred in both 2011 and 2012. We did not receive any proceeds from the sale of shares by existing stockholders in our initial public offering.

On September 12, 2012, we completed a follow-on public offering in which we and existing stockholders sold 5,548,750 shares of common stock at $28.75 per share, before underwriting discounts and commissions. We sold 1,337,500 shares and existing stockholders sold an aggregate of 4,211,250 shares, including an aggregate of 723,750 shares as a result of the underwriters' exercise of their over-allotment option. We received net proceeds of approximately $36.0 million, after deducting underwriting discounts and commissions and other expenses of the offering. We did not receive any proceeds from the sale of shares by existing stockholders in our follow-on public offering.

We have also financed a portion of our operations and acquisitions with term loans, equipment lines of credit and revolving lines of credit. In January 2009, we entered into a loan and security agreement with Comerica Bank, N.A., or Comerica, which was subsequently amended in February 2010 and December 2010. These amendments renewed the working capital line of credit for $5.0 million, and increased the term loan facility from $2.0 million to $5.0 million. In April 2012, we used a portion of the proceeds from our initial public offering to pay in full the outstanding revolving line of credit of $4.5 million and the outstanding term loan balance of $3.3 million. We allowed this line of credit to expire in April 2012.

Proceeds from transfers of our sales-type leases to third-party financial companies are allocated between the net investment in sales-type leases and the executory cost component for remaining service obligations based on relative present value. The difference between the amount of proceeds allocated to the net investment in lease and the carrying value of the net investment in lease is included in product revenue. Proceeds allocated to the executory cost component are accounted for as financing liabilities.

We are not a capital-intensive business, nor do we expect to be in the future. During 2012, 2011 and 2010, our purchases of property and equipment were $2.6 million, $2.4 million and $0.7 million, respectively. The expenditures in 2012 included progress to date on our ERP implementation, as well as spending to support headcount growth with computer and equipment needs and the build out of additional leased space available in April 2013. The expenditures in 2011 primarily related to leasehold improvements and computer equipment to support the increase in our headcount and B3000 production equipment.

We believe that our existing sources of liquidity will satisfy our anticipated working capital and capital requirements for at least the next 12 months. Our future liquidity and capital requirements will depend upon numerous factors, including our rate of growth, the rate at which we add personnel to generate and support future growth, and potential future acquisitions.

In the future, we may seek to sell additional equity securities or borrow funds. The sale of additional equity or convertible securities may result in additional dilution to our stockholders. If we raise additional funds through the issuance of debt securities or other borrowings, these securities or borrowings could have rights senior to those of our common stock and could contain covenants that could restrict our operations. Any required additional capital may not be available on reasonable terms, if at all.

Operating activities

Cash provided by operating activities was $12.3 million in 2012, due in part to net income in 2012 of $2.9 million, based on 3.3% higher gross margins on a 27% increase in revenues. Operating cash flow also excludes the following non-cash items: the mark-to-market valuation of preferred stock warrants of $1.6 million prior to our initial public offering, depreciation and amortization of $1.7 million, amortization of intangible assets of $0.9 million and stock-based compensation of $4.2 million, which was higher in 2012 due to the higher quantity and fair value of stock option and RSU grants. Additional operating cash inflows were generated by the $5.8 million increase in deferred revenues and $3.3 million increase in accrued liabilities, both driven by our continued business growth. These items were partially offset by operating cash outflows of $5.9 million for the growth-driven increase in accounts receivable, $1.2 million for the increase in prepaid expenses and other current assets, and $1.1 million for the decrease in accounts payable. We expect accounts receivable balances will fluctuate over time depending on the timing of product shipments within the given period.

Cash provided by operating activities was $5.5 million in 2011, which was primarily due to an increase in deferred revenue of $6.3 million as a result of the increase in sales in 2011, the change in accounts payable of $3.0 million, an increase in accrued liabilities of $0.9 million, stock-based compensation expense of $1.5 million, changes in the valuation of preferred stock warrants and option liabilities of $1.4 million, amortization of intangible assets of $1.0 million and depreciation and amortization of $1.0 million. This was offset by a net loss of $2.5 million and change in accounts receivable of $6.7 million due to the increase in volume and the timing of product shipments during 2011. Inventory increased $1.1 million in 2011 as we began transitioning to the B3000 badge.

Cash provided by operating activities was $4.8 million in 2010, which was primarily attributable to net income of $1.2 million plus stock-based compensation expense of $0.5 million, changes in the valuation of warrant and option liabilities of $0.4 million, depreciation and amortization of $0.7 million, amortization of intangible assets of $0.2 million and net changes in

Table of Contents

current assets and liabilities of $1.7 million. Inventory increased $1.7 million in 2010 as we elected to build inventory prior to our transition to a new contract manufacturer.

Investing activities

Cash used in investing activities was $37.5 million in 2012, which was primarily attributable to the purchase of short-term investments of $104.9 million, net of maturities received of $69.9 million, plus the purchase of property and equipment and leasehold improvements of $2.5 million.

Cash used in investing activities was $2.5 million in 2011, which was primarily attributable to the purchase of property and equipment and leasehold improvements related to expansion of our corporate offices. Our purchases of property and equipment during the year were higher than normal as we expanded our leasehold improvements and procured additional computer equipment to support the increase in headcount. We also invested in manufacturing tools and equipment to support our newly introduced B3000 badge.

Cash used in investing activities was $9.4 million in 2010, which was primarily attributable to the $8.8 million in cash, net of cash received, used for four acquisitions we completed in the last four months of 2010, and the purchase of property and equipment in the amount of $0.7 million.

Financing activities

Cash provided by financing activities was $102.9 million in 2012, which was primarily attributable to the net proceeds received from our initial public offering of $72.1 million and the net proceeds from our follow-on offering of $36.0 million, partially offset by the $8.3 million repayment of our credit facility and term loan. Additional financing activities that contributed cash included $1.7 million of proceeds from the exercise of stock options and $1.1 million of cash received for future executory costs for lease-related performance obligations.

Cash provided by financing activities was $3.2 million in 2011, which was primarily attributable to a $2.9 million net increase in debt and $1.8 million in proceeds from the exercise of stock options and preferred stock warrants offset by $1.5 million of expenses related to our initial public offering. In June 2011, we drew $4.5 million on the revolving line of credit for general corporate purposes as we added headcount and continued to invest in our operations for future growth.

Cash provided by financing activities was $4.4 million in 2010, which was primarily attributable to a $3.1 million net increase in debt and $1.2 million in proceeds from the exercise of stock options. The net increase in debt included a new $5.0 million term loan used to partially finance the four acquisitions during 2010.

As of December 31, 2012, we had $151,000 of net deferred tax liabilities and $183,000 from uncertain tax positions, both recorded within other long-term liabilities. The timing and amounts of any payments which could result from the net deferred tax liabilities and unrecognized tax benefits will depend upon a number of factors. Accordingly, the timing and amounts of any eventual payment cannot be estimated for inclusion in the table above. We do not expect a significant tax payment related to these obligations to occur within the next 12 months. Such tax contingencies are separately disclosed and discussed in Note 13.

Off-balance sheet arrangements

During 2012, we did not have any relationships with unconsolidated organizations or financial partnerships, such as structured finance or special purpose entities that would have been established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes.

Critical accounting policies and estimates

The preparation of our consolidated financial statements requires us to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. We evaluate our estimates on an ongoing basis, including those related to revenue recognition, stock-based compensation, accounting for business combinations and the provision for income taxes. We base our estimates and judgments on our historical experience, knowledge of factors affecting our business and our belief as to what could occur in the future considering available information and assumptions that we believe to be reasonable under the circumstances.

The accounting estimates we use in the preparation of our consolidated financial statements will change as events occur, more experience is acquired, additional information is obtained and our operating environment changes. Changes in estimates are made when circumstances warrant. Such changes in estimates and refinements in estimation methodologies are reflected in our reported results of operations and, if material, the effects of changes in estimates are disclosed in the notes to our consolidated financial statements. By their nature, these estimates and judgments are subject to an inherent degree of uncertainty and actual results could differ materially from the amounts reported based on these estimates.

While our significant accounting policies are more fully described in Note 1 of the “Notes to our consolidated financial statements” included in Item 8, “Financial Statements and Supplementary Data,” we believe the following reflects our critical accounting policies and our more significant judgments and estimates used in the preparation of our financial statements.

Revenue recognition

We derive revenue from the sales of communication badges, smartphones, perpetual software licenses for software that is essential to the functionality of the communication badges, software maintenance, extended warranty and professional services. We also derive revenue from the sale of licenses for software that is not essential to the functionality of the communication badges, as well as certain subscription-based revenues. Sales tax is excluded from reported total revenue.

Revenue is recognized when all of the below criteria are met:


•	there is persuasive evidence that an arrangement exists, in the form of a written contract, amendments to that contract, or purchase orders from a third party;


•	delivery has occurred or services have been rendered;


•	the price is fixed or determinable after evaluating the risk of concession; and


•	collectability is reasonably assured based on customer creditworthiness and past history of collection.

A typical sales arrangement involves multiple elements, such as sales of communications badges, perpetual software licenses, professional services and maintenance services which entitle customers to unspecified upgrades, bug fixes, patch releases and telephone support. Revenue from the sale of communication badges and perpetual software licenses is recognized upon shipment or delivery at the customers’ premises as the contractual provisions governing sales of these products do not include any provisions regarding acceptance, performance or general right of return or cancellation or termination provisions adversely affecting revenue recognition. Revenue from the sale of maintenance services on software licenses is recognized over the period during which the services are provided, which is generally one year. Revenue from professional services is recognized either on a fixed fee basis based on milestones or on a time and materials basis as the services are provided, both of which generally take place over a period of two to twelve weeks.

For contracts that were signed prior to January 1, 2010 and were not materially modified after that date, we recognize revenue on such arrangements in accordance with the discussion under the authoritative guidance for Software Revenue Recognition for all elements under such arrangements, as our software licenses sold as part of such multiple element arrangements are considered essential to the functionality of the communications system. The arrangement consideration is allocated between each element in a multiple element arrangement based on vendor-specific objective evidence, or VSOE, of fair value. We applied the residual method whereby only the fair value of the undelivered element, based on VSOE, is deferred and the remaining residual fee is recognized when delivered. We established VSOE of fair value for maintenance services based on actual renewal rates. The VSOE of fair value for professional services is based on the rates charged for those services when sold independently from a software license.

In October 2009, the Financial Accounting Standards Board, or the FASB, amended the guidance for revenue recognition for tangible products containing software components that function together to deliver the products essential functionality and also amended the accounting guidance for multiple element arrangements. We concluded that both standards were applicable to our products and arrangements and elected to early adopt these standards on a prospective basis for revenue arrangements entered into or materially modified after January 1, 2010. Under the new guidance, tangible products, containing both software and non-software components that function together to deliver a tangible product’s essential functionality, will no longer be subject to software revenue accounting.

Table of Contents

The amended guidance for multiple element arrangements:


•	provides updated guidance on whether multiple deliverables exist, how the deliverables in an arrangement should be separated and how the consideration should be allocated;


•	requires an entity to allocate revenue in an arrangement using best evidence of selling price, or BESP, if a vendor does not have vendor specific evidence, or VSOE, of fair value or third party evidence, or TPE, of fair value; and


•	eliminates the use of the residual method and require an entity to allocate revenue using the relative selling price method.

Under the new guidance, tangible products and the essential software licenses that work together with such tangible products to provide them their essential functionality are now not subject to software revenue recognition accounting rules (non-software elements), while nonessential software licenses are still governed under software revenue recognition rules (software elements). In such multiple element arrangements, we first allocate the total arrangement consideration based on the relative selling prices of the software group of elements as a whole and to the non-software elements. For our multiple-element arrangements, we allocate revenue to each element based on a selling price hierarchy at the arrangement inception. The selling price for each element is based upon the following selling price hierarchy: VSOE if available, third party evidence, or TPE, if VSOE is not available, or best estimate of selling price, or BESP, if neither VSOE nor TPE are available. We then further allocate consideration within the software group to the respective elements within that group following the authoritative guidance for software revenue recognition and our policies as described above.

We allocate revenue to all deliverables based on their relative selling prices, which for the majority of our products and services is based on VSOE of fair value. We have established VSOE of fair value for our communication badges, smartphones, software maintenance, extended warranty and professional services. VSOE of fair value is established based on selling prices when the elements are sold separately and such selling prices fall within a relatively narrow band or through actual maintenance renewal rates. We establish best evidence of selling price, or BESP, considering multiple factors including normal pricing and discounting practices, which considers market conditions, internal costs and gross margin objectives. We established BESP for perpetual licenses based on a range of actual discounts off list price, as the actual selling prices for perpetual licenses fall within a relatively narrow range.

Each element is accounted for as a separate unit of accounting provided the following criteria are met: the delivered products or services have value to the customer on a standalone basis and, for an arrangement that includes a general right of return relative to the delivered products or services, delivery or performance of the undelivered product or service is considered probable and is substantially controlled by us. We consider a deliverable to have standalone value if the product or service is sold separately by us or another vendor or could be resold by the customer. Further, our revenue arrangements do not include a general right of return. We limit the amount of revenue recognized for delivered elements to an amount that is not contingent upon future delivery of additional products or services or meeting of any specified performance conditions. The adoption of the amended revenue recognition guidance did not result in any significant changes to the individual deliverables to which we allocate revenue as the fair value for most of the deliverables is based on VSOE, or the timing of revenue recognized from the individual deliverables.

We also derive revenue from the provision of hosted services on a subscription basis and software sold under term licenses. Revenue from the sale of these products and services are not sold as part of multiple element arrangements and such arrangements are recognized ratably over the term of the arrangement.

A portion of the Company's sales are made through multi-year lease agreements with customers. When these arrangements are considered sales-type leases, upon delivery of leased products to customers, the Company recognizes revenue for such products in an amount equal to the net present value of the minimum lease payments. Unearned income is recognized as part of product revenue under the effective interest method. The Company recognizes revenue related to executory costs when such executory costs are incurred.

Proceeds from transfers of sales-type leases to third-party financial companies are allocated between the net investment in sales-type leases and the executory cost component for remaining service obligations based on relative present value. The difference between the amount of proceeds allocated to the net investment in lease and the carrying value of the net investment in lease is included in product revenue. Proceeds allocated to the executory cost component are accounted for as financing liabilities.

Stock-based compensation

Stock options

We record all stock-based awards, which consist of stock option grants, at fair value as of the grant date and recognize the expense over the requisite service period (generally over the vesting period of the award). The expenses relating to these awards have been reflected in our financial statements. Stock options granted to our employees vest over periods of 12 to 48

months. With the exception of stock options granted in connection with the acquisition of ExperiaHealth, which vested upon certain milestones being met, stock options granted to non-employees generally vest on the date of grant.

We use the Black-Scholes option-pricing model to calculate the fair value of stock options on their grant date. This model requires the following major inputs: the estimated fair value of the underlying common stock, the expected life of the option, the expected volatility of the underlying common stock over the expected life of the option, the risk-free interest rate and expected dividend yield. The following assumptions were used for each respective period for employee stock-based compensation:



	Years ended December 31,
	2012	2011	2010
Expected term (in years)	5.23 - 5.60	5.49 - 5.73	5.77
Volatility	47.9% - 48.7%	44.7% - 47.6%	44.0% - 44.5%
Risk-free interest rate	0.72% - 1.03%	0.98% - 2.48%	1.90% - 2.63%
Dividend yield	0.0%	0.0%	0.0%

At December 31, 2012, there was $7.2 million of unrecognized net compensation cost related to options which is expected to be recognized over a weighted-average period of 2.69 years. We did not grant any non-employee options in the twelve months ended December 31, 2012.

The Company bases the risk-free rate for the expected term of options on the U.S. Treasury Constant Maturity Rate as of the grant date. The computation of expected life was determined based on the historical exercise and forfeiture behavior of our employees, giving consideration to the contractual terms of the stock-based awards, vesting schedules and expectations of future employee behavior. The expected stock price volatility for our common stock was estimated based on the historical volatility of a group of comparable companies for the same expected term of our options. The comparable companies were selected based on industry and market capitalization data. We assumed the dividend yield to be zero, as we have never declared or paid dividends and do not expect to do so in the foreseeable future.

Stock-based compensation expense is recognized based on a straight-line amortization method over the respective vesting period of the award and has been reduced for estimated forfeitures. We estimated the expected forfeiture rate based on our historical experience, considering voluntary termination behaviors, trends of actual award forfeitures, and other events that will impact the forfeiture rate. To the extent our actual forfeiture rate is different from our estimate, the stock-based compensation expense is adjusted accordingly.

Restricted Stock Units

During the year ended December 31, 2012, we began incorporating restricted stock units as an element of our compensation plans. Beginning in May 2012, we granted certain employees restricted stock units, which vest one third on the first anniversary of the grant, one third on the second anniversary of the grant and one third upon the third anniversary of the grant. We did not grant any restricted stock units prior to May 2012.

Goodwill and intangible assets

We allocate the purchase price of any acquisitions to tangible assets and liabilities and identifiable intangible assets acquired. Any residual purchase price is recorded as goodwill. The allocation of the purchase price requires management to make significant estimates in determining the fair values of assets acquired and liabilities assumed, especially with respect to intangible assets. These estimates are based on information obtained from management of the acquired companies and historical experience. These estimates can include, but are not limited to, the cash flows that an asset is expected to generate in the future, and the cost savings expected to be derived from acquiring an asset. These estimates are inherently uncertain and unpredictable, and if different estimates were used the purchase price for the acquisition could be allocated to the acquired assets and liabilities differently from the allocation that we have made. In addition, unanticipated events and circumstances may occur which affect the accuracy or validity of such estimates, and if such events occur we may be required to record a charge against the value ascribed to an acquired asset or an increase in the amounts recorded for assumed liabilities.

Goodwill

Goodwill is tested for impairment at the reporting unit level at least annually as of September 30th, or more often if events or changes in circumstances indicate the carrying value may not be recoverable. No impairment was recorded in 2012, 2011 or 2010. As of December 31, 2012, no changes in circumstances indicate that goodwill carrying values may not be recoverable. Application of the goodwill impairment test requires judgment. Circumstances that could affect the valuation of goodwill include, among other things, a significant change in our business climate and the buying habits of our customers along with

changes in the costs to provide our products and services. We have identified two operating segments (Product and Service) which we also consider to be reporting units. For the 2012 goodwill impairment test, we used the qualitative assessment permitted under recent accounting guidance, and concluded there was no goodwill impairment, without proceeding to Steps 1 and 2 of the quantitative approach.

Intangible assets

In connection with the acquisitions we made in 2010, we recorded intangible assets. We applied an income approach to determine the values of these intangible assets. The income approach measures the value of an asset based on the future cash flows it is expected to generate over its remaining life. The application of the income approach requires estimates of future cash flows based upon, among other things, certain assumptions about expected future operating performance and an appropriate discount rate determined by our management. In applying the income approach, we used the excess earnings method to value our customer relationships and in-process research and development intangible assets and the relief from royalty method to value our developed technology and trade name intangible assets. We used the with-and-without method to value a non-compete intangible asset. The cash flows expected to be generated by each intangible asset were discounted to their present value equivalent using rates believed to be indicative of market participant discount rates.

Intangible assets are amortized over their estimated useful lives. Upon completion of development, acquired in process research and development assets are generally considered amortizable, finite-lived assets and are amortized over their estimated useful lives. Finite-lived intangible assets consist of customer contracts, trademarks and non-compete agreements. We evaluate our intangible assets for impairment by assessing the recoverability of these assets whenever adverse events or changes in circumstances or business climate indicate that expected undiscounted future cash flows related to such intangible assets may not be sufficient to support the net book value of such assets. An impairment is recognized in the period of identification to the extent the carrying amount of an asset exceeds the fair value of such asset. No impairment of intangible assets was recorded in 2012, 2011 or 2010.

Significant judgments required in assessing the impairment of goodwill and intangible assets include the identification of reporting units, identifying whether events or changes in circumstances require an impairment assessment, estimating future cash flows, determining appropriate discount and growth rates and other assumptions. Changes in these estimates and assumptions could materially affect the determination of fair value as to whether an impairment exists and, if so, the amount of that impairment.

Income taxes

We use the asset and liability method of accounting for income taxes. Under this method, we record deferred income taxes based on temporary differences between the financial reporting and tax bases of assets and liabilities and use enacted tax rates and laws that we expect will be in effect when we recover those assets or settle those liabilities, as the case may be, to measure those taxes. In cases where the expiration date of tax carryforwards or the projected operating results indicate that realization is not likely, we provide for a valuation allowance. Valuation allowances are established when necessary to reduce deferred tax assets to the amounts expected to be realized.

We have deferred tax assets, resulting from deductible temporary differences that may reduce taxable income in future periods. A valuation allowance is required when it is more likely than not that all or a portion of a deferred tax asset will not be realized. In assessing the need for a valuation allowance, we estimate future taxable income, considering the feasibility of ongoing tax-planning strategies and the realizability of tax loss carryforwards. Valuation allowances related to deferred tax assets can be impacted by changes in tax laws, changes in statutory tax rates and future taxable income levels. If we were to determine that we would not be able to realize all or a portion of our deferred tax assets in the future, we would reduce such amounts through a charge to income in the period in which that determination is made. Conversely, if we were to determine that we would be able to realize our deferred tax assets in the future in excess of the net carrying amounts, we would decrease the recorded valuation allowance through an increase to income in the period in which that determination is made. Due to the amount of net operating losses available for income tax purposes through December 31, 2012, we had a full valuation reserve against our deferred tax assets. We continue to evaluate the realizability of our U.S. and Canadian deferred tax assets. If our financial results improve, we will reassess the need for a full valuation allowance each quarter and, if we determine that it is more likely than not the deferred tax assets will be realized, we will adjust the valuation allowance.

Table of Contents

In the ordinary course of business, there is inherent uncertainty in quantifying our income tax positions. We assess our income tax positions and record tax benefits for all years subject to examination based upon our management’s evaluation of the facts, circumstances and information available at the reporting date. For those tax positions where it is more likely than not that a tax benefit will be sustained, we have recorded the highest amount of tax benefit with a greater than 50% likelihood of being realized upon ultimate settlement with a taxing authority that has full knowledge of all relevant information. For those income tax positions where it is not more likely than not that a tax benefit will be realizable, no tax benefit has been recognized in our financial statements.

We include interest and penalties with income taxes on the accompanying statement of operations. Our tax years after 2008 are subject to tax authority examinations. Additionally, our net operating losses and research credits prior to 2012 are subject to tax authority adjustment.

Recently issued accounting guidance

In June 2011, the FASB issued new disclosure guidance related to the presentation of the statement of comprehensive income. This guidance eliminated the previous option to report other comprehensive income, or OCI, and its components in the consolidated statement of stockholders’ equity. The requirement to present reclassification adjustments out of accumulated other comprehensive income on the face of the consolidated statement of income was deferred by FASB in December 2011. We adopted these accounting standards effective January 1, 2012; the adoption of these standards did not have any material impact on our financial position or our results of operations. In February 2013, the FASB resolved the deferred guidance on OCI reclassifications with a new rule effective in the first quarter of 2013, which is not expected to have any material impact. The latest rule on OCI reclassifications does not require any new disclosure not already required under US GAAP, but limits the alternatives to the face of the income statement or the notes, with cross-reference to other notes in certain circumstances.

In September 2011, the FASB issued new accounting guidance that simplifies goodwill impairment tests. The new guidance states that a “qualitative” assessment may be performed to determine whether further impairment testing is necessary. An entity will no longer be required to calculate the fair value of a reporting unit unless the entity determines, based on a qualitative assessment, that it is more likely than not that the fair value of the reporting unit is less than its carrying amount. Prior to the amendment, entities were required to test goodwill for impairment, on at least an annual basis, by first comparing the fair value of a reporting unit with its carrying amount, including goodwill. If the fair value of a reporting unit is calculated as being less than its carrying amount, then the second step of the quantitative test is to be performed to measure the amount of impairment loss, if any. We adopted this accounting standard effective January 1, 2012; the adoption of this standard did not have a material impact on our financial position or results of operations

We qualify as an “emerging growth company” pursuant to the provisions of the JOBS Act, enacted on April 5, 2012. Section 102 of the JOBS Act provides that an "emerging growth company” can take advantage of the extended transition period provided in Section 7(a)(2)(B) of the Securities Act for complying with new or revised accounting standards. However, we have chosen to “opt out” of such extended transition period, and as a result, we will comply with new or revised accounting standards on the relevant dates on which adoption of such standards is required for non-emerging growth companies. The decision to opt out of the extended transition period is irrevocable.

In July 2012, the FASB issued amended guidance that simplifies how entities test indefinite-lived intangible assets other than goodwill for impairment. After an assessment of certain qualitative factors, if it is determined to be more likely than not that an indefinite-lived asset is impaired, entities must perform the quantitative impairment test. Otherwise, the quantitative test is optional. The amended guidance is effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012, with early adoption permitted. The adoption of this guidance is not expected to have a material impact on our financial position or results of operations.


Item 7A.	Quantitative and Qualitative Disclosures about Market Risk

The primary objective of our investment activities is to preserve principal while at the same time maximizing yields without significantly increasing risk. To achieve this objective, historically we have invested in money market funds. With the proceeds from our two public offerings in 2012, we have invested in a broader portfolio of high credit quality short-term securities. To minimize the exposure due to an adverse shift in interest rates, we maintain an average portfolio duration of one year or less.

Table of Contents

During the six months ending December 31, 2012 we earned $145,000 of interest income on our cash equivalent and short-term investment portfolio, averaging approximately an annual pretax return of 0.3%. Therefore, in the future, if similar invested balances prevailed, a decline in market interest rates from 0.3% to zero would reduce our annual interest income by approximately $0.3 million.

Historically our operations have consisted of research and development and sales activities in the United States. As a result, our financial results have not been materially affected by factors such as changes in foreign currency exchange rates or economic conditions in foreign markets. In the fourth quarter of 2010, we acquired Wallace Wireless, Inc., a company based in Toronto, Canada. At the date of acquisition, this company had 16 employees. We expect to generate future revenue and incur future expenses associated with operating our Canadian subsidiary relating to this acquisition. We are developing plans to expand our international presence. Accordingly, we expect that our exposure to changes in foreign currency exchange rates and economic conditions will increase in future periods.

1.	The Company and Summary of Significant Accounting Policies

Background

Vocera Communications, Inc. (“the Company”) is a provider of mobile communication solutions focused on addressing critical communication challenges facing hospitals today. Vocera helps its customers improve patient safety and satisfaction, and increase hospital efficiency and productivity through its Voice Communication, Secure Messaging, and Care Transition solutions. The Voice Communication solution, which includes a lightweight, wearable, voice-controlled communication badge and a software platform, enables users to connect instantly with other hospital staff simply by saying the name, function or group name of the desired recipient. The Secure Messaging solution securely delivers text messages and alerts directly to and from smartphones, replacing legacy pagers. The Care Transition solution is a hosted voice and text based software application that captures, manages and monitors patient information when responsibility for the patient is transferred or “handed-off” from one caregiver to another, or when the patient is discharged from the hospital. These three solutions are complemented by our ExperiaHealth business, which is focused on improving patient experience.

The Company was incorporated in Delaware on February 16, 2000. The Company formed wholly-owned subsidiaries Vocera Communications UK Ltd and Vocera Communications Australia Pty Ltd. in 2005, and Vocera Hand-Off, Inc., Vocera Canada, Ltd. and ExperiaHealth, Inc. in 2010.

The Company completed its initial public offering (“IPO”) of common stock on April 2, 2012 in accordance with the Securities Act of 1933, as amended (the “Securities Act”). The Company sold 5,000,000 shares and certain of its stockholders sold 1,727,500 shares, including 877,500 shares for the underwriters' over-allotment option, through a firm commitment underwritten, public offering. The shares were sold at the price of $16.00 per share, before underwriting discounts and commissions and offering costs. The Company recorded net proceeds of $70.5 million from the IPO, after subtraction of underwriters' discounts and commissions, and offering expenses incurred in both 2011 and 2012. The Company did not receive any proceeds from the sale of shares by existing stockholders in its IPO.

On September 12, 2012, the Company completed a follow-on public offering in which the Company and existing stockholders sold 5,548,750 shares of common stock at $28.75 per share, before underwriting discounts and commissions. The Company sold 1,337,500 shares and existing stockholders sold an aggregate of 4,211,250 shares, including an aggregate of 723,750 shares as a result of the underwriters' exercise of their over-allotment option. The Company received net proceeds of approximately $36.0 million, after deducting underwriting discounts and commissions and other expenses of the offering. The Company did not receive any proceeds from the sale of shares by existing stockholders in its follow-on public offering.

Since its inception, the Company has incurred significant losses and, as of December 31, 2012, it had an accumulated deficit of $54.0 million. The Company has funded its operations primarily with customer payments for its products and services, proceeds from the issuances of convertible preferred stock, proceeds from the issuance of common stock in connection with its IPO and follow-on offering, borrowings under its term loan facility and the utilization of its line of credit. As of December 31, 2012, the Company had cash, cash equivalents and short-term investments of $127.5 million, primarily as a result of its two public offerings in 2012.

The Company believes that its existing sources of liquidity will satisfy its working capital and capital requirements for at least the next 12 months. Failure to generate sufficient revenue, achieve planned gross margins, or control operating costs may require the Company to raise additional capital through equity or debt financing. Such additional financing may not be available on acceptable terms, or at all, and could require the Company to modify, delay or abandon some of its planned future expansion or expenditures or reduce some of its ongoing operating costs, which could harm its business, operating results, financial condition and ability to achieve its intended business objectives. If the Company raises additional funds through

further issuances of equity, convertible debt securities or other securities convertible into equity, its existing stockholders could suffer significant dilution in their percentage ownership of the Company and any new securities it issues could have rights, preferences and privileges senior to those of holders of its common stock.

Basis of presentation

The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All significant inter-company transactions and balances have been eliminated in consolidation. The accompanying notes are prepared in accordance with accounting principles generally accepted in the United States (“GAAP”). Certain prior period amounts have been reclassified to be consistent with current period presentation.

The board of directors of the Company and its stockholders approved a 1-for-6 reverse stock split of the Company’s common and preferred shares that was effected on March 26, 2012. All share and per share information included in the accompanying financial statements have been adjusted to reflect this reverse stock split.

Table of Contents

Use of estimates

The preparation of financial statements in conformity with GAAP requires the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expense during the reporting periods. The estimates include, but are not limited to, revenue recognition, useful lives assigned to long-lived assets, warranty reserves, inventory reserves, the valuation of common and preferred stock and related warrants and options, stock-based compensation expense, provisions for income taxes and contingencies. Actual results could differ from these estimates, and such differences could be material to the Company’s financial position and results of operations.

Cash, cash equivalents and short-term investments

The Company’s cash equivalents and short-term investments consist of commercial paper, corporate debt securities and U.S. agency notes. These investments are classified as available-for-sale securities and are carried at fair value with the unrealized gains and losses reported as a component of stockholders’ equity. Management determines the appropriate classification of its investments at the time of purchase and reevaluates the available-for-sale designations as of each balance sheet date. The Company classifies its investments as either short-term or long-term based on each instrument’s underlying contractual maturity date. Investments with maturities of less than 12 months are classified as short-term and those with maturities greater than 12 months are classified as long-term. Investments with an original maturity of three months or less at the time of purchase are classified as cash equivalents.

Restricted cash

Cash classified as restricted on the balance sheet was $0.3 million at December 31, 2012 and 2011, respectively, the majority of which is security for a corporate travel card facility and credit card processing services. All restricted cash is current based upon the terms of the restriction on the credit card facilities.

Allowance for doubtful accounts

The allowance for doubtful accounts reflects the Company’s best estimate of probable losses inherent in the Company’s receivables portfolio determined on the basis of historical experience, specific allowances for known troubled accounts and other currently available evidence. The Company has not experienced significant credit losses from its accounts receivable. The Company performs a regular review of its customers’ payment histories and associated credit risks as it does not require collateral from its customers.

The following table presents the changes in the allowance for doubtful accounts:

Provisions charged to other accounts	—		—			—

Allowance—end of period	$	—	$	—		$	(10	)

Inventories

Inventories are valued at the lower of standard cost (which approximates actual cost on a first-in, first-out basis) or market (net realizable value or replacement cost). The Company assesses the valuation of inventory and periodically writes down the value for estimated excess and obsolete inventory based upon assumptions about future demand and market conditions.

Concentration of credit risk and other risks and uncertainties

Financial instruments that subject the Company to concentration of credit risk consist primarily of cash, cash equivalents and short-term investments. The Company’s cash and cash equivalents are primarily deposited with high quality financial institutions and in money market funds. Deposits at these institutions and funds may, at times, exceed federally insured limits. Management believes that these financial institutions and funds are financially sound and, accordingly, that minimal credit risk exists. The Company has not experienced any losses on its deposits of cash and cash equivalents. Marketable securities are stated at fair value, and accounted for as available-for-sale within short-term investments. The counterparties to the agreements

Table of Contents

relating to the Company’s investment securities consist of major corporations, financial institutions and government agencies of high credit standing.

The primary hardware component of the Company’s products is currently manufactured by a third-party contractor in Mexico. A significant disruption in the operations of this contractor may impact the production of the Company’s products for a substantial period of time, which could harm the Company’s business, financial condition and results of operations.

Concentration of credit risk with respect to trade accounts receivable is considered to be limited due to the diversity of the Company’s customer base and geographic sales areas. At December 31, 2012 and 2011, no customer accounted for 10% or more of accounts receivable. For the years ended December 31, 2012, 2011 and 2010, no customer represented 10% or more of revenue.

Property and equipment

Property and equipment are stated at cost and depreciated on a straight-line basis over the estimated useful economic lives of the assets. Assets generally have useful economic lives of three years except for leasehold improvements, which are amortized using the straight-line method over the shorter of the remaining lease term or the estimated useful life of the related assets. Upon retirement or sale, the cost and related accumulated depreciation and amortization are removed from the balance sheet and the resulting gain or loss is reflected in operations. Maintenance and repairs which are not considered improvements and do not extend the useful life of the assets are charged to operations as incurred.

The Company periodically reviews property and equipment for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset is impaired or the estimated useful lives are no longer appropriate. Fair value is estimated based on discounted future cash flows. If indicators of impairment exist and the undiscounted projected cash flows associated with such assets are less than the carrying amount of the asset, an impairment loss is recorded to write the asset down to its estimated fair values. To date, the Company has not recorded any impairment charges.

Software Development Costs.

The Company capitalizes certain internal and external costs incurred to acquire and create internal use software. Capitalized software is included in property and equipment when development is complete and is amortized on a straight-line basis over the estimated useful life of the related asset, which is approximately five years. Costs incurred prior to meeting these criteria, together with costs incurred for training and maintenance, are expensed as incurred. For the years ended December 31, 2012, 2011 and 2010, the Company capitalized costs of $1.1 million, $0.3 million and $0.2 million, respectively.

Goodwill and intangible assets

The Company allocates the purchase price of any acquisitions to tangible assets and liabilities and identifiable intangible assets acquired. Any residual purchase price is recorded as goodwill. The allocation of the purchase price requires management to make significant estimates in determining the fair values of assets acquired and liabilities assumed, especially with respect to intangible assets. These estimates are based on information obtained from management of the acquired companies and historical experience. These estimates can include, but are not limited to, the cash flows that an asset is expected to generate in the future, and the cost savings expected to be derived from acquiring an asset. These estimates are inherently uncertain and unpredictable, and if different estimates were used the purchase price for the acquisition could be allocated to the acquired assets and liabilities differently from the allocation that the Company has made. In addition, unanticipated events and circumstances may occur which may affect the accuracy or validity of such estimates. If such events occur we may be required to record a charge against the value ascribed to an acquired asset or an increase in the amounts recorded for assumed liabilities.

Goodwill

Goodwill is tested for impairment at the reporting unit level at least annually or more often if events or changes in circumstances indicate the carrying value may not be recoverable. As of December 31, 2012, no changes in circumstances indicate that goodwill carrying values may not be recoverable. Application of the goodwill impairment test requires judgment. Circumstances that could affect the valuation of goodwill include, among other things, a significant change in the Company's business climate and the buying habits of the Company's customers along with changes in the costs to provide the Company's products and services. The Company has identified two operating segments (Product and Service) which management also considers to be reporting units. For the 2012 goodwill impairment test, the Company used the qualitative assessment permitted under recent accounting guidance, and concluded there was no goodwill impairment, without proceeding to Steps 1 and 2 of the quantitative approach.

Intangible assets

In connection with the acquisitions made in 2010, the Company recorded intangible assets. The Company applied an income approach to determine the values of these intangible assets.The income approach measures the value of an asset based on the future cash flows it is expected to generate over its remaining life. The application of the income approach requires estimates of future cash flows based upon, among other things, certain assumptions about expected future operating performance and an appropriate discount rate determined by our management. In applying the income approach, the Company used the excess earnings method to value its customer relationships and in-process research and development intangible assets and the relief from royalty method to value the developed technology and trade name intangible assets. The Company used the with-and-without method to value a non-compete intangible asset. The cash flows expected to be generated by each intangible asset were discounted to their present value equivalent using rates believed to be indicative of market participant discount rates.

Intangible assets are amortized over their estimated useful lives. Upon completion of development, acquired in-process research and development assets are generally considered amortizable, finite-lived assets and are amortized over their estimated useful lives. Finite-lived intangible assets consist of customer contracts, trademarks and non-compete agreements. The Company evaluates intangible assets for impairment by assessing the recoverability of these assets whenever adverse events or changes in circumstances or business climate indicate that expected undiscounted future cash flows related to such intangible assets may not be sufficient to support the net book value of such assets. An impairment is recognized in the period of identification to the extent the carrying amount of an asset exceeds the fair value of such asset. No impairment of intangible assets was recorded in 2012, 2011 or 2010.

Convertible preferred stock warrants

Prior to the Company’s IPO, the warrants that were related to the Company’s convertible preferred stock were classified as liabilities on the Company’s consolidated balance sheet. The warrants were subject to reassessment at each balance sheet date, and any change in fair value was recognized as a component of other income (expense), net. The Company adjusted the liability for changes in fair value until the earlier of the exercise or expiration of the warrants or the completion of a liquidation event. The warrants to purchase preferred stock were converted into warrants to purchase shares of common stock at the applicable conversion rate for the related common stock upon the closing of the Company’s IPO on April 2, 2012. The common stock warrants are classified within stockholder's equity (deficit) because they are considered to be "indexed to the entity's own stock". The warrants were revalued and converted upon the closing of the IPO and as such, as of December 31, 2012, the convertible preferred stock liability is zero.

Revenue recognition

The Company derives revenue from the sales of communication badges, smartphones, perpetual software licenses for software that is essential to the functionality of the communication badges, software maintenance, extended warranty and professional services. The Company also derives revenue from the sale of licenses for software that is not essential to the functionality of the communication badges. Sales tax is excluded from reported total revenue.

Revenue is recognized when all of the below criteria are met:


•	there is persuasive evidence that an arrangement exists, in the form of a written contract, amendments to that contract, or purchase orders from a third party;


•	delivery has occurred or services have been rendered;


•	the price is fixed or determinable after evaluating the risk of concession; and


•	collectability is reasonably assured based on customer creditworthiness and past history of collection.

A typical sales arrangement involves multiple elements, such as sales of communication badges, perpetual software licenses, professional services and maintenance services which entitle customers to unspecified upgrades, bug fixes, patch releases and telephone support. Revenue from the sale of communication badges and perpetual software licenses is recognized upon shipment or delivery at the customers’ premises as the contractual provisions governing sales of these products do not include any provisions regarding acceptance, performance or general right of return or cancellation or termination provisions adversely affecting revenue recognition. Revenue from the sale of maintenance services on software licenses is recognized over the period during which the services are provided, which is generally one year. Revenue from professional services is recognized

Table of Contents

either on a fixed fee basis based on milestones or on a time and materials basis as the services are provided, both of which generally take place over a period of two to twelve weeks.

For contracts that were signed prior to January 1, 2010 and were not materially modified after that date, the Company recognizes revenue on such arrangements in accordance with the discussion under the authoritative guidance for Software Revenue Recognition, for all elements under such arrangements, as the Company’s software licenses sold as part of such multiple element arrangements are considered essential to the functionality of the communications system. The arrangement consideration is allocated between each element in a multiple element arrangement based on vendor-specific objective evidence, or VSOE, of fair value. The Company applied the residual method whereby only the fair value of the undelivered element, based on VSOE, is deferred and the remaining residual fee is recognized when delivered. The Company established VSOE of fair value for maintenance services based on actual renewal rates. The VSOE of fair value for professional services is based on the rates charged for those services when sold independently from a software license.

In October 2009, the Financial Accounting Standards Board (“FASB”) amended the guidance for revenue recognition for tangible products containing software components that function together to deliver the products essential functionality and also amended the accounting guidance for multiple element arrangements. The Company concluded that both standards were applicable to the Company’s products and arrangements and elected to early adopt these standards on a prospective basis for revenue arrangements entered into or materially modified after January 1, 2010. Under the new guidance, tangible products, containing both software and non-software components that function together to deliver a tangible product’s essential functionality, will no longer be subject to software revenue accounting.

The amended guidance for multiple element arrangements:


•	provides updated guidance on whether multiple deliverables exist, how the deliverables in an arrangement should be separated and how the consideration should be allocated;


•	requires an entity to allocate revenue in an arrangement using best evidence of selling price, or BESP, if a vendor does not have vendor specific evidence, or VSOE, of fair value or third party evidence, or TPE, of fair value; and


•	eliminates the use of the residual method and require an entity to allocate revenue using the relative selling price method.

Under the new guidance, tangible products and the essential software licenses that work together with such tangible products to provide them their essential functionality are now not subject to software revenue recognition accounting rules (non-software elements), while non-essential software licenses are still governed under software revenue recognition rules (software elements). In such multiple element arrangements, the Company first allocates the total arrangement consideration based on the relative selling prices of the software group of elements as a whole and to the non-software elements. For its multiple-element arrangements, the Company allocates revenue to each element based on a selling price hierarchy at the arrangement inception. The selling price for each element is based upon the following selling price hierarchy: VSOE if available, third party evidence, or TPE, if VSOE is not available, or best estimate of selling price, or BESP, if neither VSOE nor TPE are available. The Company then further allocate consideration within the software group to the respective elements within that group following the authoritative guidance for software revenue recognition and our policies as described above.

The Company allocates revenue to all deliverables based on their relative selling prices, which for the majority of the Company’s products and services is based on VSOE of fair value. The Company has established VSOE of fair value for its communication badges, smartphones, software maintenance, extended warranty, and professional services. VSOE of fair value is established based on selling prices when the elements are sold separately and such selling prices fall within a relatively narrow band or through actual maintenance renewal rates. The Company establishes best evidence of selling price, or BESP, considering multiple factors including normal pricing and discounting practices, which considers market conditions, internal costs and gross margin objectives. The Company established BESP for perpetual licenses based on a range of actual discounts off list price, as the actual selling prices for perpetual licenses fall within a relatively narrow range.

Each element is accounted for as a separate unit of accounting provided the following criteria are met: the delivered products or services have value to the customer on a standalone basis and, for an arrangement that includes a general right of return relative to the delivered products or services, delivery or performance of the undelivered product or service is considered probable and is substantially controlled by us. The Company considers a deliverable to have standalone value if the product or service is sold separately by us or another vendor or could be resold by the customer. Further, the Company’s revenue arrangements do not include a general right of return. The Company limits the amount of revenue recognized for delivered elements to an amount that is not contingent upon future delivery of additional products or services or meeting of any specified performance conditions. The adoption of the amended revenue recognition guidance did not result in any significant changes to the individual deliverables to which the Company allocates revenue as the fair value for most of the deliverables is based on VSOE, or the timing of revenue recognized from the individual deliverables.

Table of Contents

The Company also derives revenue from the provision of hosted services on a subscription basis and software sold under term licenses. Revenue from the sale of these products and services are not sold as part of multiple element arrangements and such arrangements are recognized ratably over the term of the arrangement.

For the year ended December 31, 2012, the Company transferred $3.8 million of lease receivables, recording an immaterial net gain and $1.1 million of financing liabilities for future performance of executory service obligations. For lease receivables retained as of December 31, 2012 the Company recorded $0.6 million of net investment in sales-type leases, equivalent to the minimum lease payments for the delivered product.

Shipping and handling costs

Shipping and handling costs charged to customers are included in revenue and the associated expense is recorded in cost of products sold in the statements of operations for all periods presented.

Research and development expenditures

Research and development costs are charged to operations as incurred. Software development costs incurred prior to the establishment of technological feasibility are included in research and development and are expensed as incurred. After technological feasibility is established, material software development costs up to general availability of the software will be capitalized and amortized on a straight-line basis over the estimated product life, or based on the ratio of current revenues to total projected product revenues, whichever is greater. To date, the time between the establishment of technological feasibility and general availability has been very short and therefore no significant costs have been incurred. Accordingly, the Company has not capitalized any software development costs.

Advertising costs

Advertising costs are included in sales and marketing expense and are expensed as incurred. Advertising costs for the years ended December 31, 2012, 2011 and 2010 were immaterial.

Product warranties

The Company offers warranties on certain products and records a liability for the estimated future costs associated with warranty claims, which is based upon historical experience and the Company’s estimate of the level of future costs. The Company provides for the estimated costs of hardware warranties at the time the related revenue is recognized. Costs are estimated based on historical and projected product failure rates, historical and projected repair costs, and knowledge of specific product failures (if any). The specific hardware warranty includes parts and labor over a period generally ranging from one to three years. The Company provides no warranty for software. The Company regularly re-evaluates its estimates to assess the adequacy of the recorded warranty liabilities and adjust the amounts as necessary. Warranty costs are reflected in the consolidated statement of operations as cost of sales.

Stock-based compensation

For options granted to employees, stock-based compensation is measured at grant date based on the fair value of the award and is expensed on a straight-line basis over the requisite service period. The Company determines the grant date fair value of the options using the Black-Scholes option-pricing model. Restricted stock awards and restricted stock units, first awarded in 2012, result in compensation expense, straightlined over the requisite service period, based on the award date closing stock price. Equity instruments issued to non-employees are recorded at their fair value on the measurement date and are subject to periodic adjustment as the underlying equity instruments vest. The fair value of options granted to non-employees is amortized over the vesting period, on a straight-line basis.

Table of Contents

For stock options issued to employees and non-employees with specific performance criteria, the Company makes a determination at each balance sheet date whether the performance criteria are probable of being achieved. Compensation expense is recognized until such time as the performance criteria are met or when it is probable that the criteria will not be met.

The Company will only recognize a tax benefit from stock-based awards in additional paid-in capital if an incremental tax benefit is realized after all other tax attributes currently available to the Company have been utilized. In addition, the Company has elected to account for the indirect effects of stock-based awards on other tax attributes, such as the research tax credit, through its statement of operations.

In 2012, the Company began incorporating restricted stock awards and RSUs as an element of our compensation plans. In February 2012, the Company granted certain of its directors restricted stock which vests 50% on the first anniversary of the grant, and 50% on the second anniversary of the grant. In May 2012, the Company granted certain employees RSUs, which vest one third on the first anniversary of the grant, one third on the second anniversary of the grant and one third upon the third anniversary of the grant.

Income taxes

The Company uses the asset and liability method of accounting for income taxes. Under this method, the Company records deferred income taxes based on temporary differences between the financial reporting and tax bases of assets and liabilities and use enacted tax rates and laws that the Company expects will be in effect when they recover those assets or settle those liabilities, as the case may be, to measure those taxes. In cases where the expiration date of tax carryforwards or the projected operating results indicate that realization is not likely, the Company provides for a valuation allowance. Valuation allowances are established when necessary to reduce deferred tax assets to the amounts expected to be realized.

The Company has deferred tax assets, resulting from net operating losses, research and development credits and temporary differences that may reduce taxable income in future periods. A valuation allowance is required when it is more likely than not that all or a portion of a deferred tax asset will not be realized. In assessing the need for a valuation allowance, the Company estimates future taxable income, considering the feasibility of ongoing tax-planning strategies and the realizability of tax loss carryforwards. Valuation allowances related to deferred tax assets can be impacted by changes in tax laws, changes in statutory tax rates and future taxable income levels. If the Company were to determine that it would not be able to realize all or a portion of its deferred tax assets in the future, it would reduce such amounts through a charge to income in the period in which that determination is made. Conversely, if it were to determine that it would be able to realize its deferred tax assets in the future in excess of the net carrying amounts, it would decrease the recorded valuation allowance through an increase to income in the period in which that determination is made. Due to the history of losses the Company has generated in the past, the Company believes that it is not more likely than not that all of the deferred tax assets in the U.S. and Canada can be realized as of December 31, 2012 and 2011, respectively. Accordingly, the Company has recorded a full valuation allowance on its deferred tax assets for these years.

At December 31, 2012, the Company had a valuation allowance against net deferred tax assets of 21.2 million. While the Company is encouraged by the pretax profit earned in 2012 and by the favorable trend in the Company's financial results, management believes it is appropriate to obtain confirmatory evidence that the improvement in the Company's results of operations is sustainable, and that realization of at least some of the deferred income tax assets is more likely than not, before reversing a portion of the valuation allowance to earnings.

The Company intends to review on a quarterly basis its conclusions about the appropriate amount of its deferred income tax asset valuation allowance. If the Company continues to generate profits in 2013 and beyond, it is likely that the US valuation allowance position will be reversed in the foreseeable future. The Company expects a significant benefit to be recorded in the period the valuation allowance reversal is recorded and a significantly higher effective tax rate in periods following the valuation allowance reversal.

In the ordinary course of business there is inherent uncertainty in quantifying the Company’s income tax positions. The Company assesses its income tax positions and records tax benefits for all years subject to examination based upon management’s evaluation of the facts, circumstances and information available at the reporting date. For those tax positions where it is more likely than not that a tax benefit will be sustained, the Company has recorded the highest amount of tax benefit with a greater than 50% likelihood of being realized upon ultimate settlement with a taxing authority that has full knowledge of all relevant information. For those income tax positions where it is not more likely than not that a tax benefit will be realizable, no tax benefit has been recognized in the financial statements.

The Company includes interest and penalties with income taxes in the accompanying statement of operations. All of the Company’s net operating losses and research credit carryforwards prior to 2012 are subject to tax authority adjustment and all years after 2008 are still subject to tax authority examinations. The Company is currently not subject to any income tax audit examinations by tax authorities in any jurisdictions including U.S. federal, state and local or foreign countries.

Foreign currency translation

The functional currency of the Company’s foreign subsidiaries is the U.S. dollar. Accordingly, monetary assets and liabilities in non-functional currency of these subsidiaries are remeasured using exchange rates in effect at the end of the period. Revenues and costs in local currency are remeasured using average exchange rates for the period, except for costs related to those balance sheet items that are remeasured using historical exchange rates. The resulting remeasurement gains and losses are included in the Company’s consolidated statements of operations. Translation gains and losses have not been significant to date.

Segments

Operating segments are components of an enterprise for which separate financial information is available and is evaluated regularly by the Company’s chief operating decision maker in deciding how to allocate resources and in assessing performance. The Company’s chief operating decision maker is the Chief Executive Officer. The Company has two operating segments which are both reportable business segments: (i) Product; and (ii) Service.

Comprehensive income (loss)

Historically, there were no components of comprehensive income which were excluded from net income (loss). For the year ended December 31, 2012, the Company had a small unrealized gain on available-for-sale securities. There were no other components within other comprehensive income for the year ended December 31, 2012.

Recent accounting pronouncements

In June 2011, the FASB issued new disclosure guidance related to the presentation of the statement of comprehensive income. This guidance eliminated the previous option to report other comprehensive income, or OCI, and its components in the consolidated statement of stockholders’ equity. The requirement to present reclassification adjustments out of accumulated other comprehensive income on the face of the consolidated statement of income was deferred by FASB in December 2011. We adopted these accounting standards effective January 1, 2012; the adoption of these standards did not have any material impact on the Company's financial position or our results of operations. In February 2013, the FASB resolved the deferred guidance on OCI reclassifications with a new rule effective in the first quarter of 2013, again not expected to have any material impact. The latest rule on OCI reclassifications does not require any new disclosure not already required under US GAAP, but limits the alternatives to the face of the income statement or the notes, with cross-reference to other notes in certain circumstances.

In September 2011, the FASB issued new accounting guidance that simplifies goodwill impairment tests. The new guidance states that a “qualitative” assessment may be performed to determine whether further impairment testing is necessary. An entity will no longer be required to calculate the fair value of a reporting unit unless the entity determines, based on a qualitative assessment, that it is more likely than not that the fair value of the reporting unit is less than its carrying amount. Prior to the amendment, entities were required to test goodwill for impairment, on at least an annual basis, by first comparing the fair value of a reporting unit with its carrying amount, including goodwill. If the fair value of a reporting unit is calculated as being less than its carrying amount, then the second step of the quantitative test is to be performed to measure the amount of impairment loss, if any. The Company adopted this accounting standard effective January 1, 2012; the adoption of this standard did not have a material impact on the financial position or results of operations of the Company.

The Company qualifies as an “emerging growth company” pursuant to the provisions of the JOBS Act, enacted on April 5, 2012. Section 102 of the JOBS Act provides that an "emerging growth company” can take advantage of the extended transition period provided in Section 7(a)(2)(B) of the Securities Act for complying with new or revised accounting standards. However, the Company is choosing to “opt out” of such extended transition period, and as a result, the Company will comply with new or revised accounting standards on the relevant dates on which adoption of such standards is required for non-emerging growth companies. The decision to opt out of the extended transition period is irrevocable.

2.	Fair value of financial instruments

The carrying values of the Company’s cash and cash equivalents and short-term investments approximate their fair value due to their short-term nature. As a basis for determining the fair value of its assets and liabilities, the Company established a three-tier fair value hierarchy which prioritizes the inputs used in measuring fair value as follows: (Level 1) observable inputs such as quoted prices in active markets; (Level 2) inputs other than the quoted prices in active markets that are observable either directly or indirectly; and (Level 3) unobservable inputs in which there is little or no market data which requires the Company to develop its own assumptions. This hierarchy requires the Company to use observable market data, when available, and to minimize the use of unobservable inputs when determining fair value. For the year ended December 31, 2012 there have been no transfers between Level 1 and Level 2 fair value instruments and no transfers in or out of Level 3.

The Company's cash and money market funds, which include bank deposits, are classified within Level 1 of the fair value hierarchy because they are valued using bank balances or quoted market prices. The Company's other cash equivalents and short-term investments are classified within Level 2 of the fair value hierarchy because they are valued by professional pricing services using market-corroborated inputs from similar instruments, rather than direct observation of quoted prices in active markets. Each security is compared to a benchmark yield at the balance sheet date, with adjustment for its specific characteristics.

The Company’s preferred stock warrants were classified within Level 3 of the fair value hierarchy because they were valued based on unobservable inputs and management’s judgment due to the absence of quoted market prices, inherent lack of liquidity and the long-term nature of such financial instruments. These assumptions are inherently subjective and involve significant management judgment.

The Company’s assets and liabilities that are measured at fair value on a recurring basis, by level, within the fair value hierarchy as of December 31, 2012 and 2011, respectively, are summarized as follows (in thousands):



	December 31, 2012								December 31, 2011

The Company performed a fair value assessment of the preferred stock warrant inputs at the end of each reporting period. The fair value of the preferred stock warrant liability was estimated using an option pricing model that takes into account the contract terms as well as multiple inputs such as the Company’s stock price, risk-free interest rates and expected volatility that the Company could not corroborate with market data. These warrants to purchase preferred stock were converted into warrants to purchase shares of common stock at the applicable conversion rate for the related common stock upon the closing of the Company's IPO on April 2, 2012. The warrants were revalued and converted upon the closing of the IPO, and as such, as of December 31, 2012 the convertible preferred stock warrant liability is zero.

For the period from January 1, 2012 through April 2, 2012, the Company valued these preferred stock warrants using a stock price of $16.00 - $23.40, risk-free interest rates of 0.07% - 0.66%, and expected volatility of 45% - 50%. For the year ending December 31, 2011 the Company used a stock price of $13.32 - $14.16, risk-free interest rates of 0.10% - 6.00%, and expected volatility of 45% - 50%. Any change in fair value was recognized as a component of other income (expense), net, in the consolidated statements of operations.

The estimated fair value of the Company's current and long-term borrowings based on a market approach was approximately $8.3 million as of December 31, 2011 and represented a Level 2 valuation. The Company did not have any current or long-term borrowings as of December 31, 2012. When determining the estimated fair value of the Company's debt, the Company used a commonly accepted valuation methodology and market-based risk measurements, such as credit risk.

As of December 31, 2012, all of the Company's available-for-sale securities have a maturity of less than one year. At December 31, 2011, the Company did not have any cash equivalents or short-term investments.


4.	Income (loss) per share

Basic and diluted net income (loss) per common share is presented in conformity with the two-class method required for participating securities. Immediately prior to the completion of the Company’s IPO on April 2, 2012, holders of Series A through Series F preferred stock were each entitled to receive non-cumulative dividends at the annual rate of 8% per share per annum, respectively, payable prior and in preference to any dividends on any shares of the Company’s common stock. In the event a dividend is paid on common stock, the holders of preferred stock were entitled to a proportionate share of any such dividend as if they were holders of common stock (on an as-if converted basis). The holders of the preferred stock did not have a contractual obligation to share in the losses of the Company. The Company considered its preferred stock to be participating securities. Additionally, the Company considers shares issued upon the early exercise of options subject to repurchase and unvested restricted shares to be participating securities as the holders of these shares have a nonforfeitable right to dividends. In accordance with the two-class method, earnings allocated to these participating securities and the related number of outstanding shares of the participating securities, which include contractual participation rights in undistributed earnings, have been excluded from the computation of basic and diluted net income (loss) per common share.

Table of Contents

Under the two-class method, net income (loss) attributable to common stockholders is determined by allocating undistributed earnings, calculated as net income less income attributable to participating securities between common stock and participating securities. In computing diluted net income (loss) attributable to common stockholders for calculation of diluted net income (loss) per share, undistributed earnings are re-allocated to reflect the potential impact of dilutive securities. Basic net income (loss) per common share is computed by dividing the net income (loss) attributable to common stockholders by the weighted-average number of common shares outstanding during the period. All participating securities are excluded from basic weighted-average common shares outstanding. Diluted net income per share attributable to common stockholders is computed by dividing the net income attributable to common stockholders for calculation of diluted net income (loss) per share by the weighted-average number of common shares outstanding, including potential dilutive common shares assuming the dilutive effect of outstanding stock options using the treasury stock method.

The following table presents the calculation of basic and diluted net income (loss) per share:

5.	Goodwill and intangible assets

Goodwill

The Company had $5.6 million of goodwill for each of the years as of December 31, 2012 and 2011. Goodwill is tested for impairment at the reporting unit level at least annually or more often if events or changes in circumstances indicate the carrying value may not be recoverable. The Company has two reporting units: Product and Service; as of December 31, 2012 all of the Company's goodwill resides in the Product reporting unit. The Company performed the annual required test of impairment of goodwill as of September 30, 2012. The Company’s annual impairment test did not indicate impairment at any of its reporting

Table of Contents

units. No impairment was recorded in 2012, 2011 or 2010. As of December 31, 2012, no changes in circumstances indicate that goodwill carrying values may not be recoverable.

Intangible assets

The fair values for acquired intangible assets were determined by management relying in part on valuations performed by independent valuation specialists. Acquisition related intangible assets are amortized over the life of the assets on a basis that resembles the economic benefit of the assets. This results in amortization that is higher in earlier periods of the useful life. To date there has been no impairment of the Company's intangible assets. The estimated useful lives and carrying value of acquired intangible assets are as follows:



		December 31, 2012						December 31, 2011
(in thousands)	Weighted average useful life (years)	Gross carrying amount		Accumulated amortization		Net carrying amount		Gross carrying amount		Accumulated amortization		Net carrying amount
Intangible assets:
Trademarks	6.9	$	70	$	30	$	40	$	70	$	16	$	54
Non-compete Agreements	2.0	70		60		10		70		13		57
Customer relationships	8.6	2,350		1,117		1,233		2,350		690		1,660
Developed technology	6.0	1,880		896		984		1,880		510		1,370
Total intangible assets, net		$	4,370	$	2,103	$	2,267	$	4,370	$	1,229	$	3,141

Amortization of intangible assets was $0.9 million, $1.0 million and $0.2 million for 2012, 2011 and 2010, respectively.

Amortization of acquired intangible assets is reflected in cost of revenue and operating expenses. The estimated future amortization of acquired intangible assets as of December 31, 2012 was as follows:



(in thousands)	Future amortization
2013	$	727
2014	567
2015	389

7.	Product Warranties

The Company provides for the estimated costs of hardware warranties at the time the related revenue is recognized. Costs are estimated based on historical and projected product failure rates, historical and projected repair costs, and knowledge of specific product failures (if any). The specific hardware warranty includes parts and labor over a period generally ranging from one to three years. The Company provides no warranty for software. The Company regularly re-evaluates its estimates to assess the adequacy of the recorded warranty liabilities and adjust the amounts as necessary.

A reconciliation of the changes in the Company’s warranty reserve for 2012, 2011 and 2010 is as follows:



	December 31,
(in thousands)	2012			2011			2010
Balance at the beginning of the period	$	983		$	605		$	572
Warranty expense accrued for shipments in period	971			1,554			1,069
Changes in liability related to pre-existing warranties	(673		)	59			177
Warranty settlements made	(984		)	(1,235		)	(1,213		)
Balance at the end of the period	$	297		$	983		$	605

The change in liability related to the pre-existing warranties for the year ended December 31, 2012 is primarily due to lower return rates on the Company's B3000 badge compared to the B2000 badge and to lower cost estimates for refurbishment and replacement alternatives.

8.	Borrowings

Term loan and revolving line of credit

In June 2004, the Company entered into a loan and security agreement with a bank which was amended in December 2010 (the “Amendment”). The Amendment renewed the revolving line of credit at $5.0 million, and increased the term loan from $2.0 million to $5.0 million. At December 31, 2011, the Company was in compliance with all loan covenants. Subsequent to the Company’ s IPO, on April 3, 2012, the Company paid off in full the outstanding revolving line of credit of $4.5 million and the outstanding term loan balance of $3.3 million. In February 2013, all asset liens relating to the expired term loan were lifted.


9.	Commitments and contingencies

The Company undertakes, in the ordinary course of business, to (i) defend customers and other parties from certain third-party claims associated with allegations of trade secret misappropriation, infringement of copyright, patent or other intellectual property right, or tortious damage to persons or property and (ii) indemnify and hold harmless such parties from certain resulting damages, costs and other liabilities. The term of these undertakings may be perpetual and the maximum potential liability of the Company under certain of these undertakings is not determinable. The Company has never incurred costs to defend lawsuits or settle claims related to these undertakings and, as a result, the Company believes the corresponding estimated fair value is minimal.

The Company has entered into indemnification agreements with its directors and officers that may require the Company to indemnify its directors and officers against liabilities that may arise by reason of their status or service as directors or officers, other than liabilities arising from willful misconduct of the individual. The Company currently has directors and officers insurance.

Non-cancelable purchase commitments

The Company enters into non-cancelable purchase commitments with its third-party manufacturer whereby the Company is required to purchase any inventory held by the third- party manufacturer that have been purchased by them based on confirmed orders from the Company. As of December 31, 2012 and 2011, approximately $4.1 million and $4.9 million, respectively, of raw material inventory was purchased and held by the third-party manufacturer which was subject to such purchase requirements.

Leases

The Company leases office space for its headquarters and subsidiaries under non cancelable operating leases, which will expire between April 2014 and April 2017. Rent expense for 2012, 2011 and 2010 was $1.9 million, $1.7 million and $1.2 million, respectively. The Company recognizes rent expense on a straight-line basis over the lease period, and has accrued for rent expense incurred but not paid.

Future minimum lease payments at December 31, 2012 under non-cancelable operating leases are as follows:



(in thousands)	Operating leases
2013	$	1,532
2014	1,545
2015	1,480
2016	440
2017 and thereafter	30
Total minimum lease payments	$	5,027

Legal matters

From time to time, the Company may be involved in lawsuits, claims, investigations and proceedings, consisting of intellectual property, commercial, employment and other matters, which arise in the ordinary course of business. The Company records a liability when it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. These provisions are reviewed at least quarterly and adjusted to reflect the impact of negotiations, settlements, ruling, advice of legal counsel and other information and events pertaining to a particular case. Litigation is inherently unpredictable. If any unfavorable ruling were to occur in any specific period, there exists the possibility of a material adverse impact on the Company’s financial position or the results of operations of that period or on the Company’s cash flows.

	13,006,868	12,154,496	52,758	53,495

There was no convertible preferred stock outstanding at December 31, 2012.

Conversion

Each share of preferred stock was convertible, at the option of the holder, into common stock. Series A, Series C, Series D, Series E and Series F had a conversion ratio of 1:1. Series B preferred stock had a conversion ratio of 1:1.8304. Each share of preferred stock automatically converted into the number of shares of common stock into which such shares were convertible at the then effective conversion ratio upon the earlier of: (1) the closing of a firm commitment underwritten public offering of common stock at a per share price of at least $15 per share with net proceeds of at least $25.0 million or (2) an affirmative vote by the majority of preferred stock stockholders. In connection with the Company’s IPO, in April 2012, each share of then-outstanding preferred stock was converted to common stock at the ratio described above.

In April 2012, the Company filed a Restated Certificate of Incorporation, which authorized the Company to issue up to 5,000,000 shares of undesignated preferred stock with a par value of $0.0003 per share, of which no shares were outstanding as of December 31, 2012.

Warrants for preferred stock

In connection with the loan and security agreement entered into in October 2005 (Note 8), the Company issued warrants to purchase 52,938 shares of Series E at an exercise price of $6.6114 per share. Upon the close of the Company’s IPO, these warrants automatically converted into warrants to purchase common stock. These warrants were cashless exercised in exchange for 37,795 shares of common stock in April 2012.

In connection with the sale of Series E in October 2005, the Company issued warrants to purchase 136,119 shares of Series E to investors who purchased Series E in October 2005 at an exercise price of $6.6114 per share. In 2011, three investors exercised warrants to purchase a total of 313 shares of Series E. In connection with the Company’s IPO, 1,956 warrants were cashless exercised in exchange for 1,147 Series E preferred shares. Upon the close of the Company’s IPO, the remaining warrants automatically converted into warrants to purchase common stock. During 2012, 55,217 of these warrants were cashless

Table of Contents

exercised in exchange for 40,692 shares of common stock. At December 31, 2012 warrants to purchase 78,633 shares of common stock were outstanding and expire in October 2015.

Outstanding warrants to purchase preferred stock were classified as liabilities, which were adjusted to fair value at each reporting period until the earlier of their exercise or expiration or the completion of a liquidation event, including the completion of an initial public offering, at which time the preferred stock warrant liability automatically converted into a warrant to purchase shares of common stock and was reclassified to stockholders’ equity (deficit). The common stock warrants are classified within stockholder's equity (deficit) because they are considered to be "indexed to the entity's own stock". The Company recorded an expense in other income (expense), net of $1.6 million, $1.0 million and $0.3 million for 2012, 2011 and 2010, respectively, to reflect the change in the fair value of these outstanding warrants.

The holders of all the warrants described in the paragraphs above may convert the warrant, in whole or in part, in lieu of exercising the warrant. The number of shares to be issued in such a conversion shall be determined by dividing (a) the aggregate fair market value of the shares issuable upon the exercise of the warrant minus the aggregate warrant price of such shares by (b) the fair market value of one share at the time of conversion.


11.	Common Stock and Share-based Compensation

The Company’s certificate of incorporation, as amended, authorizes the Company to issue 100 million shares of $0.0003 par value common stock.

At December 31, 2012, the Company has reserved shares for issuance of common stock as follows:



	Common Shares
Reserved under stock option plans	86,668
Exercise of warrants to purchase common stock	78,633
	165,301

Incentive stock option plans

The Company has three equity incentive plans: the 2000 Stock Option Plan (the “2000 Plan”), the 2006 Stock Option Plan (the “2006 Plan”) and the 2012 Stock Option Plan (the “2012 Plan”). On March 26, 2012, all shares that were reserved under the 2006 Plan but not subject to outstanding awards became available for grant under the 2012 Plan. No additional shares will be issued under the 2006 Plan. The 2000 Plan terminated in March 2010 and no additional shares will be issued under this plan. All options currently outstanding under the 2000 Plan and the 2006 Plan continue to be governed by the terms and conditions of those plans. Under the 2012 Plan, the Company has the ability to issue incentive stock options (“ISOs”), stock appreciation rights, restricted stock, restricted stock units (“RSUs”), performance awards and stock bonuses. The ISOs will be granted at a price per share not less than the fair value at date of grant. Options granted to new hires generally vest over a 4-year period with 25% vesting at the end of one year and the remaining vest monthly thereafter, options granted as merit awards generally vest monthly over a four-year period. Options granted generally are exercisable up to 10 years.

Early exercise of stock options

The Company typically allows employees to exercise options granted under the 2000 and 2006 Plans prior to vesting. The unvested shares are subject to the Company’s repurchase right at the original purchase price. The proceeds initially are recorded as an accrued liability from the early exercise of stock options (see Note 6, Balance sheet components—Accrued payroll and other accruals), and reclassified to common stock as the Company’s repurchase right lapses. At December 31, 2012 and 2011 and 2010, there were unvested shares in the amount of 48,260, 112,967 and 2,666, respectively, which were subject to repurchase at an aggregate price of $0.2 million, $0.4 million and $0 million, respectively.

Common stock subject to repurchase

Pursuant to the acquisition arrangement with Wallace Wireless, two employees were given the right to purchase 112,612 shares of common stock for $2.22 per share from the Company. Per this agreement, the Company had the right, but not the obligation, to repurchase the unvested shares of common stock upon termination of the employment of these two individuals, at the original purchase price per share. The repurchase rights with respect to the common stock lapsed over the vesting period, which was 24 months from the acquisition date. These restricted shares were legally issued and outstanding and have been included in stockholders’ equity (deficit). The amounts received in exchange for these shares were included in accrued payroll and other accruals in the accompanying consolidated balance sheet and were reclassified to equity as the shares vest. At December 31, 2012, these shares became fully vested.

At December 31, 2012, there was $7.2 million of unrecognized net compensation cost related to options which is expected to be recognized over a weighted-average period of 2.69 years.

Using the Black-Scholes option-pricing model, the weighted-average grant-date fair value of options granted to employees during 2012, 2011 and 2010 was $10.19 per share, $3.30 per share, and $0.96 per share respectively. Further information regarding the value of employee options vested and exercised during 2012, 2011 and 2010 is set forth below.

Grant-date fair value of options vested during period	$	2,256	$	881	$	469
Intrinsic value of options exercised during period	24,846		2,565		261

The Company uses the Black-Scholes option-pricing model to calculate the fair value of stock options on their grant date. This model requires the following major inputs: the estimated fair value of the underlying common stock, the expected life of the option, the expected volatility of the underlying common stock over the expected life of the option, the risk-free interest rate and expected dividend yield. The following assumptions were used for each respective period for employee stock-based compensation:



	Years ended December 31,
	2012	2011	2010
Expected Term (in years)	5.23 - 5.60	5.49 - 5.73	5.77
Volatility	47.9% - 48.7%	44.7% - 47.6%	44.0% - 44.5%
Risk-free interest rate	0.72% - 1.03%	0.98% - 2.48%	1.90% - 2.63%
Dividend yield	0.0%	0.0%	0.0%

Prior to the Company’s IPO, the risk-free rate for the expected term of options was based on the U.S. Treasury Constant Maturity Rate as of the grant date. The computation of expected life was determined based on the historical exercise and forfeiture behavior of the Company’s employees, giving consideration to the contractual terms of the stock-based awards, vesting schedules and expectations of future employee behavior. The expected stock price volatility for the Company’s common stock was estimated based on the historical volatility of a peer group of publicly-traded companies for the same expected term of the options. The peer group was selected based on industry and market capitalization data. The Company

assumed the dividend yield to be zero, as the Company has never declared or paid dividends and does not expect to do so in the foreseeable future.

Employee Stock Purchase Plan

In March 2012, the Company's 2012 Employee Stock Purchase Plan (the “ESPP”) was approved. The ESPP allows eligible employees to purchase shares of the Company's common stock at a discount through payroll deductions of up to 15% of their eligible compensation, subject to any plan limitations. The ESPP provides for six-month offering periods, except for the first offering period which is for 11 months, and at the end of each offering period, employees are able to purchase shares at 85% of the lower of the fair market value of the Company's common stock on the first trading day of the offering period or on the last day of the offering period. No shares were purchased under the plan in 2012.

The Company used the following assumptions to estimate the fair value of the ESPP offered for the year ended December 31, 2012: expected term of 6-11 months, volatility of 43.2% - 50.0%, risk-free interest rate of 0.14% - 0.18% and dividend yield of zero.

Restricted Stock Awards and Restricted Stock Units

In 2012, the Company began incorporating restricted stock awards and RSUs as an element of its compensation plans. In February 2012, the Company granted certain of its directors restricted stock awards which vests 50% on the first anniversary of the grant, and 50% on the second anniversary of the grant. In May 2012, the Company granted certain employees RSUs, which vest one third on the first anniversary of the grant, one third on the second anniversary of the grant and one third upon the third anniversary of the grant.

A summary of the restricted stock activity for the year ended December 31, 2012 is presented below:

Non-Employee Stock-Based Compensation

For the years ended December 31, 2012, 2011 and 2010, the Company granted zero, 67,916 and 84,166 options to non-employees, respectively. Of the 84,166 options granted during the year ended December 31, 2010, 83,333 were granted in connection with the acquisition of ExperiaHealth, which the Company issued contingent upon certain revenue milestones being met for 2010 and 2011. All other options granted to non-employees during the three years ended December 31, 2012 were fully vested on the date of grant. Stock-based compensation expense related to stock options granted to non-employees is recognized as the stock option vests, or if fully vested, on the date of grant. For stock options issued to non-employees with specific performance criteria, the Company makes a determination at each balance sheet date whether the performance criteria are probable of being achieved. Compensation expense is recognized at the time it is determined that it is probable the performance criteria will be met.

The fair value of the stock options granted to non-employees was calculated using the Black-Scholes option-pricing model with the following assumptions:

For the years ended December 31, 2012, 2011 and 2010, the Company recognized expenses of approximately $29,000, $907,000 and $100,000, respectively, related to these options.

Allocation of Stock-Based Compensation Expense

Stock-based compensation expense is recognized based on a straight-line amortization method over the respective vesting period of the award and has been reduced for estimated forfeitures. The Company estimated the expected forfeiture rate based on its historical experience, considering voluntary termination behaviors, trends of actual award forfeitures, and other events that will impact the forfeiture rate. To the extent the Company’s actual forfeiture rate is different from the estimate, the stock-based compensation expense is adjusted accordingly.

12.	Segments

The Company has two operating segments which are both reportable business segments: (i) Product; and (ii) Service, which are comprised of the Company’s and its wholly-owned subsidiaries’ results from operations. Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker (CODM), or decision making group, in deciding how to allocate resources and in assessing performance. The Company’s CODM is its Chief Executive Officer.

The CODM regularly receives information related to revenue, cost of revenue, and gross profit for each operating segment, and uses this information to assess performance and make resource allocation decisions. All other financial information, including operating expenses and assets, is prepared and reviewed by the CODM on a consolidated basis.

Assets are not a measure used to assess the performance of the Company by the CODM, therefore the Company does not report assets by segment internally or in its financial statements.

Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. The following table presents the significant components of the Company’s deferred tax assets and liabilities for the periods presented:



	As of December 31,

The Company determines its valuation allowance on deferred tax assets by considering both positive and negative evidence in order to ascertain whether it is more likely than not that deferred tax assets will be realized. Realization of deferred tax assets is dependent upon the generation of future taxable income, if any, the timing and amount of which are uncertain. Due to the history of losses the Company has generated in the past, the Company believes that it is not more likely than not that all of the deferred tax assets in the U.S. and Canada can be realized as of December 31, 2012; accordingly, the Company has recorded a full valuation allowance on its deferred tax assets. While the Company is encouraged by the pretax profit earned in 2012 and by the favorable trend in the Company's financial results, management believes it is appropriate to obtain confirmatory evidence that the improvement in the Company's results of operations is sustainable, and that realization of at least some of the deferred income tax assets is more likely than not, before reversing a portion of the valuation allowance to earnings. The Company intends to review on a quarterly basis its conclusions about the appropriate amount of its deferred income tax asset valuation allowance. If the Company continues to generate profits in 2013 and beyond, it is likely that the US valuation allowance position will be reversed in the foreseeable future. The Company expects a significant benefit to be recorded in the period the valuation allowance reversal is recorded and a significantly higher effective tax rate in periods following the valuation allowance reversal.

The Company’s valuation allowance decreased by $1.5 million and increased by $0.5 million for the years ended December 31, 2012 and 2011, respectively. The $1.5 million decrease during 2012 in the valuation allowances was primarily due to the utilization of loss carryforwards and changes in temporary differences between tax and financial statement recognition of revenue and expense. The increase during 2011 was primarily driven by increases in reserves and accruals.

Included the net operating loss carryovers below is approximately $15 million of federal net operating loss and approximately $4 million of state net operating loss carryovers attributable to excess stock option deductions. According to the authoritative guidance, concerning when tax benefits related to excess stock option deductions can be credited to paid-in capital, the related

Table of Contents

valuation allowance cannot be reversed, even if the facts and circumstances indicate that it is more likely than not that the deferred tax asset can be realized. The valuation allowance will only be reversed as the related deferred tax asset is applied to reduce taxes payable. The Company follows the authoritative guidance for ordering to determine when such NOL has been realized.

At December 31, 2012, the Company had $48.0 million and $52.0 million, respectively, of federal and state net operating loss carryforwards. The federal net operating loss carryforward begins expiring in 2015, and the state net operating loss carryforward begins expiring in 2013, if not utilized.

In addition, the Company has federal research and development tax credits carryforwards of approximately $2.0 million and state research and development tax credit carryforwards of approximately $2.0 million. The federal credit carryforwards begin expiring 2021 and the state credits carry forward indefinitely. The Internal Revenue Code contains provisions which limit the amount of net operating loss and research credit carryforwards that can be used in any given year if a significant change in ownership has occurred.

The following table displays by contributing factor the changes in the valuation allowance for deferred tax assets since January 1, 2010:



	Years Ended December 31,

Balance at the end of the period	$	21,193		$	22,687		$	21,588

The following table reflects changes in the unrecognized tax benefits since January 1, 2011:



	Years ended December 31,

Decreases related to prior year tax provisions	—		(1		)
Increases related to current year tax provisions	164		234
Gross amount of unrecognized tax benefits as of the end of the period	$	1,079	$	908

As a result of the Company’s historic losses and related valuation allowances, the Company has recorded the uncertain tax amounts above entirely as reductions to deferred tax assets which are subject to a full valuation allowance in its consolidated balance sheet. The Company recognizes interest and penalties relating to uncertain tax positions in income tax expense. As of December 31, 2012 and 2011, penalties and interest were zero for all periods. As the Company is not currently under examination, it is reasonable to assume that the balance of gross unrecognized tax benefits will likely not change in the next twelve months.

The Company files income tax returns in the United States on federal basis and various states. The Company is not currently under any United States federal, state and local, or non-U.S. income tax examinations by tax authorities for any taxable years. The Company's Canadian tax return is currently under audit for the year ended December 31, 2011. All of the Company’s net operating losses and research credit carryforwards prior to 2012 are subject to tax authority adjustment and all years after 2008 are still subject to the tax authority examinations.

The Company has not provided for U.S. federal and foreign withholding taxes on $0.5 million of the Company’s non-U.S. subsidiaries’ undistributed earnings as of December 31, 2012, because such earnings are considered indefinitely reinvested in its international operations.

Item 9A.	Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Disclosure controls and procedures are designed to ensure that information required to be disclosed by us in reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission's rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed in reports filed under the Exchange Act is accumulated and communicated to management, including principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure. There are inherent limitations to the effectiveness of any system of disclosure controls and procedures, including the possibility of human error and the circumvention or overriding of the controls and procedures. Accordingly, even effective disclosure controls and procedures can only provide reasonable assurance of achieving their control objectives.

Table of Contents

As of December 31, 2012 we have carried out an evaluation under the supervision of, and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures as defined in Rules 13a-15(e) and 15d-15(e) of the Exchange Act. Based on our evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of December 31, 2012.

Exemption from Management's Report on Internal Control Over Financial Reporting

This report does not include a report of management's assessment regarding internal control over financial reporting or an attestation report of our independent registered public accounting firm due to a transition period established by rules of the SEC for newly public companies.

Prior Material Weakness in Internal Control over Financial Reporting

A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of our financial statements will not be prevented or detected and corrected on a timely basis.

In connection with our preparation of the financial statements for six months ended June 30, 2012, adjustments to our financial statements were identified which resulted from a control deficiency that we considered to constitute a material weakness. This control deficiency related to the design and operation of controls for the preparation of the statement of cash flows as we did not maintain effective controls to ensure the accuracy and appropriate presentation and disclosure of the statement of cash flows. Specifically, the controls were not designed to consider non-cash activity related to issuance costs from the completion of our IPO. The material weakness resulted in material errors and adjustments to cash flows from operating and financing activities included within the condensed consolidated financial statements for the period ended June 30, 2012. Additionally, this material weakness could have resulted in financial information or disclosures that would constitute a material misstatement of our interim condensed consolidated financial statements and/or year-end consolidated financial statements that might not have been prevented or detected.

Remediation Plan Execution and Status

In response to the identified material weakness in the Statement of Cash Flows, our management, with oversight from our Audit Committee, executed the implementation of the following remediation steps beginning in the quarter ended September 30, 2012. These efforts were focused on (i) redesigning the statement of cash flow spreadsheet, specifically related to non-cash items; (ii) completing a second more detailed review of the statement of cash flows at the end of each period; (iii) adopting an enhanced secondary review of the statement of cash flows, by agreeing each movement to supporting schedule and recalculating the amounts in the worksheet; and (iv) employing the services of external consultants to assist with the completion of the review.

We believe these steps, which are now fully implemented, have addressed the material weakness previously identified and have enhanced our internal control over financial reporting, as well as our disclosure controls and procedures. However, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Changes in Internal Control over Financial Reporting

As described above, we executed the remediation plan for an existing material weakness identified in the second quarter of 2012. There were no other changes in our internal control over financial reporting which occurred during the quarter ended December 31, 2012 which has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
