Statement regarding use of non-GAAP financial measures
The company reports non-GAAP results for diluted earnings per share, net income, gross margin, operating expenses, including research and development expense, selling general and administrative expense, legal contingency and settlement, and goodwill and intangible impairment, operating income, operating margin, gross profit, other income (expense), tax provision, constant currency revenue and growth, and free cash flow (on a consolidated and, as applicable, segment basis) in addition to, and not as a substitute for, or superior to, financial measures calculated in accordance with GAAP. The company’s financial measures under GAAP include substantial charges such as amortization of acquired intangible assets among others that are listed in the reconciliations of GAAP and non-GAAP financial measures included in this press release, as well as the effects of currency translation. Management has excluded the effects of these items in non-GAAP measures to assist investors in analyzing and assessing past and future operating performance. Non-GAAP net income, diluted earnings per share and operating margin are key components of the financial metrics utilized by the company’s board of directors to measure, in part, management’s performance and determine significant elements of management’s compensation.
The company encourages investors to carefully consider its results under GAAP, as well as its supplemental non-GAAP information and the reconciliation between these presentations, to more fully understand its business. Reconciliations between GAAP and non-GAAP results are presented in the tables of this release.
The company provides forward-looking guidance on a non-GAAP basis, including on a constant currency basis for revenue and revenue growth rates. The company is unable to provide a reconciliation of forward-looking non-GAAP financial measures to the most directly comparable GAAP reported financial measures because it is unable to predict with reasonable certainty the impact of items such as acquisition-related expenses, fair value adjustments to contingent consideration, gains and losses from strategic investments, potential future asset impairments, restructuring activities, the ultimate outcome of pending litigation, and currency exchange rate fluctuations without unreasonable effort. These items are uncertain, inherently difficult to predict, depend on various factors, and could have a material impact on GAAP reported results for the guidance period. For the same reasons, the company is unable to address the significance of the unavailable information, which could be material to future results.
