Earnings Per Share

We compute basic earnings per share by dividing net income attributable to Dolby Laboratories, Inc. by the weighted-average number of shares of Class A and Class B common stock outstanding during the period. For diluted earnings per share, we divide net income attributable to Dolby Laboratories, Inc. by the sum of the weighted-average number of shares of Class A and Class B common stock outstanding and the potential number of dilutive shares of Class A and Class B common stock outstanding during the period.

The following table sets forth the computation of basic and diluted earnings per share attributable to Dolby Laboratories, Inc.:
