Note Regarding Use of Non-GAAP Financial Measures

Broadcom reports cost of product revenue, product gross profit, product gross margin and income from operations in accordance with GAAP and supplementally on a non-GAAP basis. Broadcom’s presentation of non-GAAP cost of product revenue, non-GAAP product gross profit, non-GAAP product gross margin excludes certain charges related to acquisitions, stock-based compensation expense and employer payroll tax expense on certain stock option exercises. In addition to the exclusions noted above, our non-GAAP income from operations also excludes settlement costs and impairment of long-lived assets. Stock-based compensation expense primarily includes the impact of stock options and restricted stock units issued by Broadcom. Reconciliations of our GAAP to non-

GAAP financial measures for the three months ended March 31, 2011 and 2010 appear in the financial statements portion of this release titled “Unaudited Schedule of Selected GAAP to Non-GAAP Adjustments” and “Unaudited Reconciliation of GAAP Income from Operations to Non-GAAP Income from Operations.”

Broadcom believes that the presentation of these non-GAAP measures provide important supplemental information to management and investors regarding financial and business trends relating to our financial condition and results of operations. Broadcom’s management believes that the use of these non-GAAP financial measures provides consistency and comparability among and between results from prior periods or forecasts and future prospects, and also facilitates comparisons with other companies in our industry, many of which use similar non-GAAP financial measures to supplement their GAAP results. Broadcom’s management has historically used these non-GAAP financial measures when evaluating operating performance, because we believe that the inclusion or exclusion of the items described above provides insight into our core operating results, our ability to generate cash and underlying business trends affecting our performance. Broadcom has chosen to provide this information to investors to enable them to perform additional analyses of past, present and future operating performance and as a supplemental means to evaluate our ongoing core operations. The non-GAAP financial information presented herein should be considered supplemental to, and not as a substitute for, or superior to, financial measures calculated in accordance with GAAP.

For additional information on the items excluded by Broadcom from one or more of its non-GAAP financial measures, refer to the Form 8-K regarding this release furnished today to the Securities and Exchange Commission.

The forecasts and projections contained in the table above should not be regarded as representations by Broadcom that the estimated results will be achieved. Projections and estimates are necessarily speculative in nature and actual results may vary materially from the guidance we provide today.

The guidance set forth in the above table should be read together with the information under the caption, “Cautions regarding Forward-Looking Statements” above, our Annual Report on Form 10-K for the year ended December 31, 2010, subsequent Quarterly Reports on Form 10-Q, recent Current Reports on Form 8-K, and our other Securities and Exchange Commission filings.
