Use of Non-GAAP Financial Measures
The Company occasionally utilizes financial measures and terms not calculated in accordance with accounting principles generally accepted in the United States (“GAAP”) in order to provide investors with an alternative method for assessing our operating results in a manner that enables investors to more thoroughly evaluate our current performance as compared to past performance. We also believe the non-GAAP measures provide investors with a better baseline for modeling the Company’s future earnings expectations. Our management uses these non-GAAP measures for the same purpose. We believe that our investors should have access to the same set of tools that we use in analyzing our results. These non-GAAP measures should be considered in addition to results prepared in accordance with GAAP, but should not be considered a substitute for or superior to GAAP results. The Company’s calculation of EBITDA and Return on Net Assets is not necessarily comparable to similarly titled measures reported by other companies. We have provided definitions below for certain non-GAAP financial measures, together with an explanation of why management uses these measures and why management believes that these non-GAAP financial measures are useful to investors. In addition, we have provided tables with the Earnings Release to reconcile some of the non-GAAP financial measures utilized therein to their equivalent GAAP financial measures.
We define EBITDA as GAAP net income before depreciation and amortization, interest expense, and income taxes. Our management uses EBITDA as a supplemental measure in the evaluation of our business and believes that EBITDA provides a meaningful measure of our performance because it eliminates the effects of period to period changes in taxes, costs associated with capital investments and interest expense. EBITDA is not a financial measure calculated in accordance with GAAP. Accordingly, it should not be considered in isolation or as a substitute for net income or other financial measures prepared in accordance with GAAP. When evaluating EBITDA, investors should consider, among other factors, (i) increasing or decreasing trends in EBITDA, (ii) whether EBITDA has remained at positive levels historically, and (iii) how EBITDA compares to our debt outstanding. We provide a reconciliation of EBITDA to GAAP net income. Because EBITDA excludes some, but not all, items that affect net income and may vary among companies, the EBITDA presented by the Company may not be comparable to similarly titled measures of other companies. EBITDA does not give effect to the cash we must use to service our debt or pay income taxes and thus does not reflect the funds generated from operations or actually available for capital investments.
This measure is calculated as earnings before interest and taxes divided by average net assets. Our management uses RONA as a supplemental measure in the evaluation of our business. Management believes that RONA is a meaningful performance measure because it considers the assets used to generate earnings. RONA is not a financial measure calculated in accordance with GAAP. Accordingly, it should not be considered in isolation or as a



substitute for net income as an indicator of company performance, or as a substitute for cash flows from operating activities as a measure of liquidity. When evaluating RONA, investors should consider, among other factors, increasing or decreasing trends in RONA and whether RONA has remained at positive levels historically. We provide a reconciliation of RONA to GAAP net income.
Other Definitions
Market Share
Our market share calculation compares commodity price-adjusted change in sales to estimated changes in housing starts on a same-store basis. Estimated housing starts represent permits obtained in our markets lagged one month to become an assumed start.
