Q:	When is the Proxy Statement being sent to stockholders and what is its purpose?

A:	This Proxy Statement is first being sent to our stockholders on or about May 6, 2013 at the direction of our board of directors in order to solicit proxies for our use at the Annual Meeting.

Q:	When is the Annual Meeting and where will it be held?

A:	The Annual Meeting will be held on Tuesday, June 4, 2013, at 9:00 a.m., local time, at our corporate office, located at 27422 Portola Parkway, Suite 200, Foothill Ranch, California 92610.

Q:	Who may attend the Annual Meeting?

A:	All of our stockholders may attend the Annual Meeting.

Q:	Who is entitled to vote?

A:	Stockholders as of the close of business on April 12, 2013 are entitled to vote at the Annual Meeting. Each share of our common stock is entitled to one vote.

Q:	On what am I voting?

A:	You will be voting on:

•	The election of three members to our board of directors to serve until our 2016 annual meeting of stockholders;

•	The approval, on a non-binding, advisory basis, of the compensation of our named executive officers as disclosed in this Proxy Statement;

•	The ratification of the selection of Deloitte & Touche LLP as our independent registered public accounting firm for 2013; and

•	Such other business as may properly come before the Annual Meeting or any adjournments.

Q:	How does the board of directors recommend that I vote?

A:	The board of directors recommends that you vote your shares:

•	“FOR ALL” the director nominees identified in “Proposals Requiring Your Vote - Proposal for Election of Directors” below;

•	“FOR” the approval of the compensation of our named executive officers as disclosed in this Proxy Statement; and

•	“FOR” the ratification of the selection of Deloitte & Touche LLP as our independent registered public accounting firm for 2013.

Q:	How can I vote?

A:	You can vote in person at the Annual Meeting or you can vote prior to the Annual Meeting by proxy. Whether or not you plan to attend the Annual Meeting, we urge you to vote by proxy without delay.

---

Q:	How do I vote by proxy?

A:	If you choose to vote your shares by proxy, you have the following options:

•	Over the Internet: You can vote over the Internet at the website shown on your proxy card. Internet voting will be available 24 hours a day, seven days a week, until 11:59 p.m., Eastern Time, on Monday June 3, 2013.

•	By telephone: You can vote by telephone by calling the toll-free number shown on your proxy card. Telephone voting will be available 24 hours a day, seven days a week, until 11:59 p.m., Eastern Time, on Monday, June 3, 2013.

•	By mail: You can vote by mail by completing, signing and dating your proxy card and returning it in the enclosed prepaid envelope.

Q:	I want to attend the Annual Meeting and vote in person. How do I obtain directions to the Annual Meeting?

A:	You may obtain directions to the Annual Meeting by calling us at (949) 614-1740.

Q:	What constitutes a quorum?

A:

As of April 12, 2013, the record date, 19,002,504 shares of our common stock were issued and outstanding. A majority of these shares present or represented by proxy will constitute a quorum for the transaction of business at the Annual Meeting. If you properly vote by proxy by submitting your voting instructions over the Internet, by telephone or by mail, then your shares will be counted as part of the quorum. Abstentions or votes that are withheld on any matter will be counted towards a quorum but will be excluded from the vote relating to the particular matter under consideration. Broker non-votes are counted towards a quorum but are excluded from the vote with respect to the matters for which they are applicable. A broker non-vote occurs when a broker holding shares for a beneficial owner does not vote on a particular proposal because the broker does not have discretionary voting power with respect to that proposal and has not received instructions with respect to that proposal from the beneficial owner. Among our proposals, brokers will have discretionary voting power only with respect to the proposal to ratify the selection of Deloitte & Touche LLP as our independent registered public accounting firm for 2013.

Q:	What are the voting requirements for the proposals?

A:	There are different voting requirements for the proposals.

•	Directors will be elected by a plurality vote of all votes cast for the election of directors at the Annual Meeting. Accordingly, the three nominees receiving the highest number of votes will be elected. If you withhold authority to vote for any particular director nominee, your shares will not be counted in the vote for that nominee and will have no effect on the outcome of the vote.

•

The approval of the holders of a majority of the total number of outstanding shares of our common stock present in person or represented by proxy at the Annual Meeting and actually voted on the proposal is necessary (1) to approve, on a non-binding, advisory basis, the compensation of our named executive officers as disclosed in this Proxy Statement, and (2) to ratify the selection of Deloitte & Touche LLP as our independent registered public accounting firm for 2013. If you abstain from voting on the proposal to approve the compensation of our named executive officers as disclosed in this Proxy Statement, the proposal to ratify the selection of Deloitte & Touche LLP as our independent registered public accounting firm for 2013, or both proposals, your shares will not be counted in the vote for such proposal(s) and will have no effect on the outcome of the vote.

Q:	If my shares are held in “street name” by my broker, will my broker vote my shares for me?

A:	As discussed above, among our proposals, brokers will have discretionary voting power only with respect to the proposal to ratify the selection of Deloitte & Touche LLP as our independent registered public accounting firm for 2013. To be sure your shares are voted, you should instruct your broker to vote your shares using the instructions provided by your broker.

---

Q:	What will happen if the compensation of the company's named executive officers is not approved by the stockholders?

A:

Because this is an advisory vote, our board of directors and compensation committee will not be bound by the approval of, or the failure to approve, the executive compensation of our named executive officers as disclosed in this Proxy Statement. The board of directors and the compensation committee, however, value the opinions that our stockholders express in their votes and will consider the outcome of the vote when determining future executive compensation programs.

Q:	What will happen if the selection of Deloitte & Touche LLP as our independent registered public accounting firm for 2013 is not ratified by stockholders?

A:

Pursuant to the audit committee charter, the audit committee of our board of directors has sole authority to appoint our independent registered public accounting firm, and the audit committee will not be bound by the ratification of, or failure to ratify, the selection of Deloitte & Touche LLP. The audit committee will, however, consider any failure to ratify the selection of Deloitte & Touche LLP in connection with the appointment of our independent registered public accounting firm the following year.

Q:	Can I change my vote after I give my proxy?

A:	Yes. If you vote by proxy, you can revoke that proxy at any time before voting takes place at the Annual Meeting. You may revoke your proxy by:

•	attending the Annual Meeting and voting in person.

Q:	What does it mean if I receive more than one proxy card?

A:	If you receive more than one proxy card, it is because your shares are held in more than one account. You must vote each proxy card to ensure that all of your shares are voted at the Annual Meeting.

Q:	Who will count the votes?

A:	Representatives of Computershare, our transfer agent, will tabulate the votes and act as inspectors of election.

Q:	How much will this proxy solicitation cost?

A:

We have hired MacKenzie Partners, Inc. to assist us in the distribution of proxy materials and solicitation of votes at a cost not to exceed $4,500, plus out-of-pocket expenses. We will reimburse brokerage firms and other custodians, nominees and fiduciaries for their reasonable out-of-pocket expenses for forwarding proxy and solicitation materials to the owners of our common stock. Our officers and regular employees may also solicit proxies, but they will not be specifically compensated for these services. In addition to the use of the mail, proxies may be solicited personally or by telephone by our employees or by MacKenzie Partners.

•

Our adjusted net assets of $728 million as of December 31, 2011 was determined by adjusting our reported net assets as of December 31, 2011 of $873 million pursuant to the terms of the 2012 STI Plan to, among other things, exclude assets and liabilities of the Secondary Aluminum business unit, financing items, VEBA assets and liabilities, capital expenditures in progress, income tax assets and liabilities and derivative assets and liabilities;

The restrictions on 100% of the shares of restricted stock granted will lapse on March 5, 2015 or earlier if the named executive officer's employment terminates as a result of death or disability, the named executive officer's employment is terminated by us without cause, the named executive officer's employment is voluntarily terminated by him for good reason or in the event of a change in control. If the named executive officer's employment terminates before March 5, 2015 as a result of his retirement at or after age 65, the shares of restricted stock granted to him will remain outstanding and the restrictions on 100% of such shares will lapse on March 5, 2015. The number of shares of restricted stock was calculated by dividing the applicable percentage (i.e., 36% for Mr. Hockema and 50% for the other named executive officers) of the target monetary value by the sum of (i) the closing price of our company's common stock on the grant date, which was $47.44 per share on March 5, 2012, reduced by (ii) 11.53%, the discount factor provided by Meridian to reflect the design characteristics, including the vesting period, of the restricted stock.

(2)	The table below sets forth the number of performance shares that will vest for each of Messrs. Hockema, Rinkenberger, Donnan, Bunin and Harvey under our 2012 - 2014 LTI Program at the threshold, target and maximum performance levels:

---

•	the threshold number of performance shares reflects that no performance shares will vest in 2015 under our 2012-2014 LTI Program unless the Company's performance exceeds the threshold performance required over the 2012 through 2014 performance period;

•

the target number of performance shares was calculated by dividing the applicable percentage (i.e., 64% for Mr. Hockema and 50% for the other named executive officers) of the target monetary value by the sum of (i) the closing price of our company's common stock on the grant date, which was $47.44 per share on March 5, 2012, reduced by (ii) 25.93%, the discount factor provided by Meridian in connection with the calculation of the economic value of the performance shares for purposes of determining the number of performance shares to be granted on the grant date; and

•	the maximum number of performance shares was calculated by dividing an amount equal to twice the target monetary value by the economic value of each performance share on the grant date.

•	the Kaiser Aluminum Savings and Investment Plan, a tax-qualified profit-sharing and 401(k) plan (which we refer to as our Savings Plan); and

•	a nonqualified and unsecured deferred compensation plan intended to restore benefits that would be payable to designated participants in the Savings Plan but for the limitations on benefit accruals and payments imposed by the Internal Revenue Code of 1986 (which we refer to as our Restoration Plan).

•	A company match of the employee's pre-tax deferrals under our Savings Plan;

•	A company contribution to the employee's account under our Savings Plan; and

•	A company contribution to the employee's account under our Restoration Plan.

---

•	provide an economic incentive for Mr. Hockema to delay his retirement until at least July 2015;

•	improve our ability to retain other key members of senior management; and

•	provide assurance to our customers and other stakeholders of the continuity of senior management for an extended period.

Reflects the aggregate grant date fair value of restricted stock and performance share awards to our named executive officers determined in accordance with Financial Accounting Standards Board Accounting Standard Code Topic 718 (referred to herein as ASC Topic 718), without regard to potential forfeiture. The aggregate grant date fair value of the performance share awards reflected in this table has been determined assuming the probable outcome of the performance condition on the date of the grant and without adjustment for actual performance during the period. The aggregate grant date fair value of the 2012 performance share awards determined assuming the probable outcome of the performance condition and assuming an outcome of the performance condition at the maximum level are as follows:

(2)	Reflects payments earned under our short-term incentive plans.

(3)

Reflects the aggregate change in actuarial present value of the named executive officer's accumulated benefit under a defined pension benefit plan previously maintained by us for our salaried employees, which we refer to as our Old Pension Plan, during the applicable fiscal year, calculated by (a) assuming mortality according to the RP - 2000WC mortality table projected 23 years with Scale AA and (b) applying a discount rate of 4.70%, 3.75% and 3.40% per annum for 2010, 2011and 2012, respectively, to determine the actuarial present value of the accumulated benefit at December 31 of the preceding year and a discount rate of 4.70%, 3.75% and 3.40% per annum, respectively, to determine the actuarial present value of the accumulated benefit at December 31 of the applicable year. Effective December 17, 2003, the Pension Benefit Guaranty Corporation, or PBGC, terminated and effectively assumed responsibility for making benefit payments in respect of our Old Pension Plan, whereupon all benefit accruals under the Old Pension Plan ceased and benefits available thereunder to certain salaried employees, including Mr. Hockema, were significantly reduced due to the limitations on benefits payable by the PBGC. Above-market or preferential earnings are not available under our Restoration Plan, which is our only plan or arrangement pursuant to which compensation may be deferred on a basis that is not tax-qualified, or any of our other benefit plans.

(4)	Includes contributions made or to be made by us under our Savings Plan. For 2012, includes contributions as follows: Mr. Hockema, $26,925; Mr. Rinkenberger, $25,000; Mr. Donnan, $25,000; Mr. Bunin, $25,000; and Mr. Harvey, $29,387.

The named executive officer will receive all dividends and other distributions paid with respect to the shares of restricted stock he holds, but if any of such dividends or distributions are paid in shares of our capital stock, such shares will be subject to the same restrictions on transferability as are the shares of restricted stock with respect to which they were paid.

(2)	Assumes that there is no earned but unpaid base salary at the time of termination.

(3)

Under our 2012 STI Plan, Mr. Hockema's target award for 2012 was $569,000, but his award could have ranged from a threshold of $284,500 to a maximum of $1,707,000, or could have been zero if the threshold performance was not achieved. Mr. Hockema's award under our 2012 STI Plan was determined in March 2013 to be $974,533. Pursuant to Mr. Hockema's employment agreement, we must pay Mr. Hockema or his estate any earned but unpaid short-term incentive unless his employment is terminated by us for cause. Under Mr. Hockema's employment agreement, if his employment had been terminated during 2012 but prior to December 31, 2012, Mr. Hockema's target award for 2012 under our 2012 STI Plan would have been prorated for the actual number of days of Mr. Hockema's employment in 2012 and Mr. Hockema would have been entitled to payment of such amount, without any increase or reduction that would normally be considered with his award, unless his employment had been terminated by us for cause. Under Mr. Hockema's employment agreement, if his employment had been terminated on December 31, 2012, the last day of our 2012 fiscal year, Mr. Hockema would have been entitled to full payment of his award under the 2012 STI Plan unless his employment had been terminated by us for cause or had been voluntarily terminated by him.

(4)	Assumes that Mr. Hockema used all of his 2012 vacation and that he has four weeks of accrued vacation for 2013.

(5)	Under Mr. Hockema's employment agreement, if Mr. Hockema's employment is terminated by us without cause or is voluntarily terminated by him for good reason, we must make a lump-sum payment to Mr. Hockema in an amount equal to two times the sum of his base salary and target annual bonus opportunity for the fiscal year in which such termination occurs.

(6)

Under Mr. Hockema's employment agreement, if Mr. Hockema's employment is terminated by us without cause or is voluntarily terminated by him for good reason within two years following a change in control, we must make a lump-sum payment to Mr. Hockema in an amount equal to three times the sum of his base salary and target annual bonus opportunity for the fiscal year in which such termination occurs.

(7)	Under Mr. Hockema's employment agreement, if Mr. Hockema's employment is terminated by us without cause or is voluntarily terminated by him for good reason, we must continue his medical and dental benefits for two years, or, if such termination occurs within two years following a change in control, three years, commencing on the date of such

(8)

Under Mr. Hockema's employment agreement, if Mr. Hockema's employment is terminated by us without cause or is voluntarily terminated by him for good reason, we must continue his disability benefits for two years, or, if such termination occurs within two years following a change in control, three years, commencing on the date of such termination. This table reflects the present value of such disability benefits at December 31, 2012 determined (a) based on our current costs of providing such benefits and assuming such costs do not increase during the applicable benefit continuation period, (b) assuming we pay such costs throughout the applicable benefit continuation period in the same manner as we currently pay such costs, (c) assuming mortality according to the RP-2000 Combined Health mortality table published by the Society of Actuaries, and (d) applying a discount rate of 3.75% per annum.

(9)

Reflects the actuarial present value of Mr. Hockema's disability benefits at December 31, 2012 determined (a) assuming full disability at December 31, 2012, (b) assuming mortality according to the RP-2000 Disabled Retiree mortality table published by the Society of Actuaries, and (c) applying a discount rate of 3.40% per annum. Such disability benefits would be paid by a third-party insurer and not by us.

(10)

Under Mr. Hockema's employment agreement, if Mr. Hockema's employment is terminated by us without cause or is voluntarily terminated by him for good reason, we must continue his life insurance benefits for two years, or, if such termination occurs within two years following a change in control, three years, commencing on the date of such termination. The table reflects the present value of such life insurance benefits at December 31, 2012 determined (a) assuming coverage throughout the applicable benefit continuation period at Mr. Hockema's current election of the maximum available coverage, (b) based on our current costs of providing such benefits and assuming such costs do not increase during the applicable benefit continuation period, (c) assuming we pay such costs throughout the applicable benefit continuation period in the same manner as we currently pay such costs, (d) assuming mortality according to the RP-2000 Combined Health mortality table published by the Society of Actuaries, and (e) applying a discount rate of 3.40% per annum.

(11)

Reflects the life insurance benefit payable assuming Mr. Hockema's death had occurred on December 31, 2012 other than while traveling on company-related business. Such life insurance benefit would have been paid by a third-party insurer and not by us. We maintain a travel and accidental death policy for certain employees, including Mr. Hockema, that would provide a $1,000,000 death benefit payable to Mr. Hockema's estate if his death occurs during company-related travel. Such death benefit would be paid by a third-party insurer and not by us.

(12)

We do not have an obligation to make excise payments to Mr. Hockema. Mr. Hockema's employment agreement, as amended and restated, instead provides that, if any payments to Mr. Hockema would be subject to a federal excise tax by reason of being considered contingent on a change in control, then such payments will be reduced to the minimum extent necessary so that no portion of such payments, as so reduced, is subject to such tax, except that such a reduction will be made only if and to the extent such reduction would result in an increase in the aggregate payment on an after-tax basis. It is estimated that, if Mr. Hockema's employment had been terminated on December 31, 2012 by us without cause or by him for good reason following a change in control on such date, no payments owing to Mr. Hockema would have been subject to a federal excise tax by reason of being considered contingent on a change in control and, accordingly, no such payments would have been reduced.

(13)

If, on December 31, 2012, Mr. Hockema's employment had been terminated as a result of his death or disability, his employment had been terminated by us without cause or his employment had been voluntarily terminated by him for good reason, or if there had been a change in control, then (a) the restrictions on all shares of restricted stock held by Mr. Hockema would have lapsed, (b) the performance shares granted to him effective March 5, 2010 would have remained outstanding, with the number of shares of common stock, if any, to be received by Mr. Hockema in respect of such performance shares to be determined based on the performance level achieved during the applicable three-year performance period, and (c) the target number of performance shares granted to him effective March 5, 2011 and March 5, 2012 would have vested; in such circumstances, the table reflects the aggregate market value, determined based on a per share price of $61.69, the closing price per share of our common stock as reported on the Nasdaq Global Select Market on December 31, 2012, of a number of shares equal to the sum of (i) all shares of restricted stock held by Mr. Hockema, (ii) 8,263, the actual number of shares of common stock received by Mr. Hockema in respect of the performance shares granted to him effective March 5, 2010 based on the performance level achieved during the applicable three-year performance period as determined by our compensation committee in early 2013, and (iii) the target number of shares of common stock that could be received by Mr. Hockema in respect of the performance shares granted to him effective March 5, 2011 and March 5, 2012. If Mr. Hockema had retired on December 31, 2012, then all shares of restricted stock and

Reflects the spread, if any, of (a) the aggregate market value of the shares of common stock purchasable upon exercise of the option rights which would have vested early due to Mr. Hockema's termination, determined based on a per share price of $61.69, the closing price per share of common stock as reported on the Nasdaq Global Select Market on December 31, 2012, over (b) the aggregate exercise price required to purchase such shares upon exercise of such option rights. All option rights held by Mr. Hockema on December 31, 2012 had previously vested. Accordingly, no spread is reported in this table.

(15)

Under our Restoration Plan, Mr. Hockema is entitled to a distribution of his account balance six months following his termination, except that he will forfeit the entire amount of matching and fixed rate contributions made by us to his account if his employment is terminated for cause. In addition, under our Savings Plan, upon termination of employment, Mr. Hockema is eligible to receive a distribution of his vested balance under the plan; however, such balance is not reflected in this table.

(1)	Notwithstanding the fact that Mr. Rinkenberger had not reached age 65 as of December 31, 2012, this column is provided for illustrative purposes.

(2)	Assumes that there is no earned but unpaid base salary at the time of termination.

Under our 2012 STI Plan, Mr. Rinkenberger's target award for 2012 was $265,000, but his award could have ranged from a threshold of $132,500 to a maximum of $795,000, or could have been zero if the threshold performance was not achieved. Mr. Rinkenberger's award under our 2012 STI Plan was determined in March 2013 to be $453,869. If Mr. Rinkenberger's employment had terminated on December 31, 2012, Mr. Rinkenberger would have been entitled to full payment of his award under the 2012 STI Plan unless his employment had been terminated by us for cause or voluntarily terminated by him other than for good reason. Under the 2012 STI Plan, Mr. Rinkenberger would have been entitled to a pro rata award under the 2012 STI Plan if his employment had been terminated during 2012 but prior to December 31, 2012 and his employment had been terminated as a result of death, disability, normal retirement or full early retirement (position elimination), had been terminated by us without cause or had been voluntarily terminated by him for good reason. Under Mr. Rinkenberger's Change in Control Agreement, if his employment had been terminated by us without cause or by him for good reason within the period commencing 90 days prior to a change in control and ending two years following a change in control and such termination had occurred during 2012 other than on December 31, 2012, Mr. Rinkenberger's target award for 2012 under our 2012 STI Plan would have been prorated for the actual number of days of Mr. Rinkenberger's employment in 2012 and Mr. Rinkenberger would have been entitled to payment of such amount.

(4)	Assumes that Mr. Rinkenberger used all of his 2012 vacation and that he has five weeks of accrued vacation for 2013.

(5)

Under our Salaried Severance Plan, if Mr. Rinkenberger's employment is terminated by us without cause, Mr. Rinkenberger is entitled to a lump-sum payment equal to his weekly base salary multiplied by a number of weeks (not to exceed 26), which we refer to as the continuation period, determined based on his number of years of full employment. As of December 31, 2012, Mr. Rinkenberger's continuation period was 20 weeks.

(6)

Under Mr. Rinkenberger's Change in Control Agreement, if Mr. Rinkenberger's employment is terminated by us without cause or is voluntarily terminated by him for good reason within the period beginning 90 days prior to a change in control and ending two years following a change in control, Mr. Rinkenberger is entitled to a lump-sum payment equal to two times the sum of his base salary and most recent short-term incentive target.

Under our Salaried Severance Plan, if Mr. Rinkenberger's employment is terminated by us without cause, Mr. Rinkenberger is entitled to continuation of his medical and dental benefits following the termination of employment for a period not to exceed the shorter of his continuation period and the period commencing on the termination of employment and ending on the date he is no longer eligible for coverage under COBRA. This table reflects the present value of such medical and dental benefits at December 31, 2012 determined (a) assuming family coverage in a point of service medical plan and a premium dental plan throughout Mr. Rinkenberger's continuation period and (b) based on current COBRA coverage rates for 2013.

This table reflects the present value of such disability benefits at December 31, 2012 determined (a) assuming coverage through out the benefit continuation period, (b) based on our current costs of providing such benefits and assuming such costs do not increase during the applicable benefit continuation period, (c) assuming we pay such costs throughout the applicable benefit continuation period in the same manner as we currently pay such costs, (d) assuming mortality according to the RP-2000 Combined Health mortality table published by the Society of Actuaries, and (d) applying a discount rate of 3.40% per annum.

Reflects the actuarial present value of Mr. Bunin's disability benefits at December 31, 2012 determined (a) assuming full disability at December 31, 2012, (b) assuming mortality according to the RP-2000 Disabled Retiree mortality table published by the Society of Actuaries, and (c) applying a discount rate of 3.75% per annum. Such disability benefits would be paid by a third-party insurer and not by us.

Under our Salaried Severance Plan, if Mr. Bunin's employment is terminated by us without cause, Mr. Bunin is entitled to continuation of his life insurance benefits following the termination of employment for a period not to exceed the shorter of his continuation period and the period commencing on the termination of employment and ending on the date he is no longer eligible for coverage under COBRA. This table reflects the present value of such life insurance benefits at December 31, 2012 determined (a) assuming coverage throughout Mr. Bunin's continuation period at his current election of the maximum available coverage, (b) based on our current costs of providing such benefits and assuming such costs do not increase during Mr. Bunin's continuation period, (c) assuming we pay such costs throughout Mr. Bunin's continuation period in the same manner as we currently pay such costs, (d) assuming mortality according to the RP-2000 Combined Health mortality table published by the Society of Actuaries, and (e) applying a discount rate of 3.40% per annum.

Reflects the life insurance benefit payable assuming Mr. Bunin's death had occurred on December 31, 2012 other than while traveling on company-related business. Such life insurance benefit would have been paid by a third-party insurer and not by us. We maintain a travel and accidental death policy for certain employees, including Mr. Bunin, that would provide an additional $1,000,000 death benefit payable to Mr. Bunin's estate if his death occurs during company-related travel. Such death benefit would be paid by a third-party insurer and not by us.

(15)

Under Mr. Bunin's Change in Control Agreement, if Mr. Bunin's employment is terminated by us without cause or is voluntarily terminated by him for good reason within the period commencing 90 days prior to a change in control and ending two years following a change in control, we must continue his perquisites for two years commencing on the date of such termination. This table reflects the estimated cost to us of continuing Mr. Bunin's perquisites for such two-year period as follows: vehicle allowance, $23,942. Such amount has been estimated by multiplying the cost of Mr. Bunin's vehicle allowance for 2012 by two.

(16)

Under Mr. Bunin's Change in Control Agreement, in general, if any payments to Mr. Bunin would be subject to federal excise tax or any similar state or local tax by reason of being considered contingent on a change in control, we must pay to Mr. Bunin an additional amount such that, after satisfaction of all tax obligations imposed on such payments, Mr. Bunin retains an amount equal to the federal excise tax or similar state or local tax imposed on such payments. However, if no such federal excise tax or similar state or local tax would apply if the aggregate payments were reduced by 5%, then the aggregate payments to Mr. Bunin will be reduced by the amount necessary to avoid application of such federal excise tax or similar state or local tax. This table reflects an estimate of any such additional amount that we would have been obligated to pay Mr. Bunin, or any such reduction to the aggregate payments to Mr. Bunin that would have occurred, if his employment had been terminated on December 31, 2012 by us without cause or by him for good reason following a change in control on such date.

(17)

If, on December 31, 2012, Mr. Bunin's employment had been terminated as a result of his death or disability, his employment had been terminated by us without cause or his employment had been voluntarily terminated by him for good reason, or if there had been a change in control, then (a) the restrictions on all shares of restricted stock held by Mr. Bunin would have lapsed, (b) the performance shares granted to him effective March 5, 2010 would have remained outstanding, with the number of shares of common stock, if any, to be received by Mr. Bunin in respect of such performance shares to be determined based on the performance level achieved during the applicable three-year performance period, and (c) the target number of performance shares granted to him effective March 5, 2011 and March 5, 2012 would have vested; in such circumstances, this table reflects the aggregate market value, determined based on a per share price of $61.69, the closing price per share of our common stock as reported on the Nasdaq Global Select Market on December 31, 2012, of a number of shares equal to (i) all shares of restricted stock held by Mr. Bunin, (ii) 2,671, the actual number of shares of common stock received by Mr. Bunin in respect of the performance shares granted to him effective March 5, 2010 based on the performance level achieved during the applicable three-year performance period as determined by our compensation committee in early 2013, and (iii) the target number of shares of common stock that could be received by Mr. Bunin in respect of the performance shares granted to him effective March 5, 2011 and March 5, 2012. If Mr. Bunin had qualified for retirement on December 31, 2012 and he had retired on such date, then (a) the shares of restricted stock granted to Mr. Bunin effective March 5, 2010, March 5, 2011 and March 5, 2012 would have remained outstanding and the restrictions on such shares would lapse on March 5, 2013, March 5, 2014 and March 5, 2015, respectively, and (b) the performance shares granted to Mr. Bunin effective March 5, 2010, March 5, 2011 and March 5, 2012 would have remained outstanding with the number of shares of common stock, if any, to be received by Mr. Bunin in respect of such performance shares to be determined based on the performance level achieved during the applicable three-year performance periods; in such circumstances, the table reflects the aggregate market value, determined based on a per share price of $61.69, the closing price per share of our common stock as reported on the Nasdaq Global Select Market on December 31, 2012, of a number of shares equal to the sum of (i) all shares of restricted stock granted to Mr. Bunin effective March 5, 2010, March 5, 2011 and March 5, 2012, (ii) 2,671, the actual number of shares of common stock received by Mr. Bunin in respect of the performance shares granted to him effective March 5, 2010 based on the performance level achieved during the applicable three-year performance period as determined by our compensation committee in early 2013, and (iii) the target number of shares of common stock that could be received by Mr. Bunin in respect of the performance shares granted to him effective March 5, 2011 and March 5, 2012.

(18)

Reflects the spread, if any, of (a) the aggregate market value of the shares of common stock purchasable upon exercise of the option rights which would have vested early due to Mr. Bunin's termination, determined based on a per share price of $61.69, the closing price per share of our common stock as reported on the Nasdaq Global Select Market on December 31, 2012, over (b) the aggregate exercise price required to purchase such shares upon exercise of such option rights. All option rights that were held by Mr. Bunin on December 31, 2012 had previously vested. Accordingly, no spread is reflected in this table because the $80.01 per share exercise price of such option rights exceeded the $61.69 closing price per share of our common stock as reported on the Nasdaq Global Select Market on December 31, 2012.

Under our Restoration Plan, Mr. Bunin is entitled to a distribution of his account balance six months following his termination, except that he will forfeit the entire amount of matching and fixed rate contributions made by us to his account if he is terminated for cause.

Under our 2012 STI Plan, Mr. Harvey's target award for 2012 was $240,000, but his award could have ranged from a threshold of $120,500 to a maximum of $720,000, or could have been zero if the threshold performance was not achieved. Mr. Harvey's award under our 2012 STI Plan was determined in March 2013 to be $411,051. If Mr. Harvey's employment had terminated on December 31, 2012, Mr. Harvey would have been entitled to full payment of his award under the 2012 STI Plan unless his employment had been terminated by us for cause or voluntarily terminated by him other than for good reason. Under the 2012 STI Plan, Mr. Harvey would have been entitled to a pro rata award under the 2012 STI Plan if his employment had been terminated during 2012 but prior to December 31, 2012 and his employment had been terminated as a result of death, disability, normal retirement or full early retirement (position elimination), had been terminated by us without cause or had been voluntarily terminated by him for good reason. Under Mr. Harvey's Change in Control Agreement, if his employment had been terminated by us without cause or by him for good reason within the period commencing 90 days prior to a change in control and ending two years following a change in control and such termination had occurred during 2012 other than on December 31, 2012, Mr. Harvey's target award for 2012 under our 2012 STI Plan would have been prorated for the actual number of days of Mr. Harvey's employment in 2012 and Mr. Harvey would have been entitled to payment of such amount.
