Non-GAAP Financial Measures In this earnings release and during the earnings conference call and webcast as described above, Oplink will discuss certain non-GAAP financial measures. Generally, a non-GAAP financial measure is a numerical measure of a company's performance, financial position, or cash flows that either excludes or includes amounts that are not normally excluded or included in the most directly comparable measure calculated and presented in accordance with GAAP. A reconciliation between non-GAAP and GAAP measures can be found in the accompanying tables. Oplink believes that providing these non-GAAP measures to its investors provides investors the benefit of viewing Oplink's performance using the same financial metrics that the management team uses in making many key decisions and evaluating how Oplink's "core operating performance" and its results of operations may look in the future. Oplink defines "core operating performance" as its on-going performance in the ordinary course of its operations. Items that are non-recurring or do not involve cash expenditures, such as one-time tax benefits or charges, impairment charges, restructuring charges, amortization of intangible assets and non-cash compensation related to stock and options, are not included in Oplink's view of "core operating performance."
