Non-GAAP Financial Measures

In addition to GAAP reporting, Avago provides investors with net income, income from operations, gross margin, operating expenses and other data, on a non-GAAP basis. This non-GAAP information includes the effect of purchase accounting on revenues, excludes amortization of intangible assets, share-based compensation expense, restructuring charges, acquisition-related costs, purchase accounting effect on inventory, loss from discontinued operations and income tax effects of non-GAAP reconciling adjustments. Management does not believe that these items are reflective of the Company’s underlying performance. The presentation of these and other similar items in Avago’s non-GAAP financial results should not be interpreted as implying that these items are non-recurring, infrequent or unusual. Avago believes this non-GAAP financial information provides additional insight into the Company’s on-going performance and has therefore chosen to provide this information to investors for a more consistent basis of comparison and to help them evaluate the results of the Company’s on-going operations and enable more meaningful period to period comparisons. These non-GAAP measures are provided in addition to, and not as a substitute for, or superior to, measures of financial performance prepared in accordance with GAAP. A reconciliation between GAAP and non-GAAP financial data is included in the supplemental financial data attached to this press release.
