Use of non-GAAP (Adjusted) Financial Measures The information furnished in this release includes non-GAAP financial measures that differ from measures calculated in accordance with generally accepted accounting principles in the United States of America (GAAP), including EBITDA, adjusted EBITDA, non-GAAP gross margin as a percentage of revenue, and non-GAAP operating income. EBITDA is defined as net income (loss) before income taxes, interest expense, interest income and depreciation and amortization. Adjusted EBITDA is EBITDA further adjusted to exclude certain charges and other adjustments as described in our SEC filings. We believe that including supplementary information concerning Adjusted EBITDA is appropriate because it serves as a basis for determining management and employee compensation. In addition, we believe Adjusted EBITDA provides more comparability between our historical results and results that reflect purchase accounting and our current capital structure. Accordingly, Adjusted EBITDA measures our financial performance based on operational factors that management can impact in the short-term, such as our pricing strategies, volume, costs and expenses of the organization and it presents our financial performance in a way that can be more easily compared to prior quarters or fiscal years. EBITDA and Adjusted EBITDA have limitations as analytical tools. EBITDA measures do not represent net income (loss) or cash flow from operations as those terms are defined by GAAP and do not necessarily indicate whether cash flows will be sufficient to fund cash needs. While EBITDA measures are frequently used as measures of operations and the ability to meet debt service requirements, these terms are not necessarily comparable to other similarly titled captions of other companies due to the potential inconsistencies in the method of calculation. Adjusted EBITDA excludes the impact of earnings or charges resulting from matters that we consider not to be indicative of our ongoing operations. In particular, our formulation of Adjusted EBITDA allows the addition of certain non-cash charges that are deducted in calculating net income (loss), and restructuring charges, certain fees payable to our private equity sponsors and other specific cash costs and expenses and that portion of our pension costs, other post-employment benefits costs, and non-retirement post-employment benefits costs representing the amortization of pension service costs and actuarial gain or loss associated with these employment benefits as set forth in the reconciliation of GAAP to non-GAAP numbers shown below. However, these are expenses that may recur, may vary and are difficult to predict. Non-GAAP gross margin excludes the amortization of acquired technology intangible assets, share based compensation, impairment of long lived assets and purchase accounting adjustments. We have included non-GAAP gross margin because we believe it provides additional useful information to investors regarding our operations by excluding those charges that management does not believe are reflective of the Company’s ongoing operating results when assessing the performance of the business. Non-GAAP operating income excludes the amortization of technology intangible assets, restructuring and impairment charges, acquisition and integration related costs, third party sales transformation costs, share based compensation, impairment of long lived assets and purchase accounting adjustments. We have included non-GAAP operating income because we believe it provides additional useful information to investors regarding our operations by excluding those charges that management does not believe are reflective of the company’s ongoing operating results when assessing the performance of the business. These non-GAAP measures are not based on any comprehensive set of accounting rules or principles and have limitations as analytical tools in that they do not reflect all of the amounts associated with Avaya’s results of operations as determined in accordance with GAAP. As such,

these measures should only be used to evaluate Avaya's results of operations in conjunction with the corresponding GAAP measures.
