Comprehensive Income [Abstract]

Comprehensive Income

11. Comprehensive Income

Our comprehensive income generally consists of net income plus the effect of unrealized gains and losses on our investments, primarily due to temporary changes in market value of certain of our ARS investments. In addition, we recognize the noncredit portion of other-than-temporary impairment on debt securities in comprehensive income. We recognize foreign currency remeasurement adjustments in our consolidated statement of income as the U.S. dollar is the functional currency of our foreign entities.

Our comprehensive income was as follows (in thousands):
