Note Regarding Use of Non-GAAP Financial Measures

Broadcom reports the following measures in accordance with GAAP and on a non-GAAP basis: (i) cost of product revenue, (ii) product gross profit, (iii) product gross margin, (iv) research and development and selling, general and administrative expense (v) net income, (vi) weighted average shares outstanding (diluted) and (vii) diluted net income per share. Broadcom’s presentation of non-GAAP cost of product revenue, non-GAAP product gross profit, and 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 net income and diluted net income per share (EPS) also exclude settlement costs, charitable contributions, non-recurring legal fees, restructuring costs (reversals) 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 and nine months ended September 30, 2011 and 2010 appear in the financial statements portion of this release under the heading “Unaudited Schedule of Selected GAAP to Non-GAAP Adjustments.”

Broadcom believes that the presentation of these non-GAAP measures provides 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
