Wesco Aircraft cannot assure you that the assumptions made in preparing any of the forward-looking statements will prove accurate or that any long-term financial goals will be realized.  All forward-looking statements included in this presentation speak only as of the date made, and Wesco Aircraft undertakes no obligation to update or revise publicly any such forward-looking statements, whether as a result of new information, future events, or otherwise.  In particular, Wesco Aircraft cautions you not to place undue weight on certain forward-looking statements pertaining to potential growth opportunities, long-term financial projections or goals, future growth or the value we currently ascribe to certain attributes set forth herein.  Actual results may vary significantly from these statements.  Wesco Aircraft’s business is subject to numerous risks and uncertainties, which may cause future results of operations to vary significantly from those presented herein, including those highlighted in the section entitled “Risk Factors” in Wesco Aircraft’s Annual Report on Form 10-K for the fiscal year ended September 30, 2012 filed with the Securities and Exchange Commission on November 30, 2012. Wesco Aircraft discloses Adjusted EBITDA and Adjusted Net Income, which are non-GAAP measures its management uses to evaluate its business, because it believes they assist investors and analysts in comparing its performance across reporting periods on a consistent basis by excluding items that Wesco Aircraft does not believe are indicative of its core operating performance. Wesco Aircraft believes these metrics are used in the financial community, and it presents these metrics to enhance investors’ understanding of its operating performance and cash flow. You should not consider Adjusted EBITDA and Adjusted Net Income as an alternative to net income, determined in accordance with GAAP, as an indicator of operating performance, or as an alternative to net cash provided by operating activities, determined in accordance with GAAP, as an indicator of Wesco Aircraft’s cash flow. See the Appendix for reconciliations of Adjusted EBITDA and Adjusted Net Income to GAAP net income.

Wesco utilizes and discusses Adjusted Net Income, Adjusted Basic EPS, Adjusted Diluted EPS and Adjusted EBITDA, which are non-GAAP measures our management uses to evaluate our business, because we believe they assist investors and analysts in comparing our performance across reporting periods on a consistent basis by excluding items that we do not believe are indicative of our core operating performance. We believe these metrics are used in the financial community, and we present these metrics to enhance investors’ understanding of our operating performance.  You should not consider Adjusted EBITDA and Adjusted Net Income as an alternative to Net Income, determined in accordance with GAAP, as an indicator of operating performance.  Adjusted Net Income, Adjusted Basic EPS, Adjusted Diluted EPS and Adjusted EBITDA are not measurements of financial performance under GAAP, and these metrics may not be comparable to similarly titled measures of other companies.
