Comprehensive Income

Comprehensive income consists of two elements, net income and other comprehensive income. Other comprehensive income items are recorded in the stockholders’ equity section of our balance sheets and excluded from net income. Our other comprehensive income consists of unrealized gains and losses on marketable debt and equity securities classified as available-for-sale and foreign currency translation adjustments for subsidiaries with functional currencies other than the U.S. dollar.

The following table shows the components of comprehensive income, net of income taxes, for the periods indicated.
