Non-GAAP Financial Measures

Sonus Networks presents its financial statements in accordance with accounting principles generally accepted in the United States ("GAAP"). Many of our investors have requested that we disclose non-GAAP information because it is useful in understanding our ongoing performance and comparing it to our historical results, as our non-GAAP financial measures exclude certain non-cash and one-time charges or benefits. Likewise, we use non-GAAP measures that exclude certain expenses, such as stock-based compensation expense, amortization of intangible assets and restructuring charges, in analyzing and assessing the overall performance of our business, making operating decisions, planning and forecasting future periods, and determining payments under compensation programs. We exclude stock-based compensation expense and amortization of intangible assets because these charges are non-cash in nature. We exclude restructuring charges because they are one-time events. No adjustment to income taxes for non-GAAP items was required, as we were unable to recognize a tax benefit on domestic losses incurred in any of the periods presented. We believe that non-GAAP financial measures, including gross profit, gross margin, operating expenses, net income (loss) and earnings (loss) per share, are useful when evaluating our ongoing operations and comparing them to our historical results, including our liquidity.

Whenever we use a non-GAAP financial measure, we provide a reconciliation of the non-GAAP financial measure to the most closely applicable GAAP financial measure. Investors are encouraged to review the related GAAP financial measures and the reconciliation of these non-GAAP financial measures to their most directly comparable GAAP financial measure.

Our non-GAAP financial measures are not presented in accordance with, nor are they intended to be a substitute for, GAAP financial measures. In addition, our presentations of these measures may not be comparable to similarly titled measures used by other companies. Our non-GAAP financial measures should not be considered alternatives for, or in isolation from, the financial information prepared and presented in accordance with GAAP. Investors are cautioned that there are material limitations associated with the use of non-GAAP financial measures as analytical tools. In particular, many of the adjustments to our GAAP financial measures reflect the exclusion of items that are recurring and will be reflected in our financial results for the foreseeable future.
