The change in net unrealized gains (losses) on available-for-sale securities recorded in Other comprehensive loss includes unrealized gains (losses) that arose from changes in market value of specifically identified securities that were held during the period, gains (losses) that were previously unrealized, but have been recognized in current period net income due to sales, as well as prepayments of available-for-sale investments purchased at a premium. This reclassification has no effect on total comprehensive income or equity and was not material for all periods presented. See Note 11 for more information related to comprehensive income.

The average remaining maturities of the Company’s short-term and long-term available-for-sale investments at March 31, 2014 were approximately seven months and three years, respectively.

Realized Gains and Losses on Available-for-sale Investments

For the three months ended March 31, 2014 and 2013, the Company received proceeds from the sales of available-for-sale investments of $266.4 million and $231.8 million, respectively. The Company had realized gains on the sales of available-for-sale investments during the three months ended March 31, 2014 and 2013 of $0.3 million and $0.2 million, respectively. For the three months ended March 31, 2014 and 2013, the Company had realized losses on available-for-sale investments of $0.1 million, primarily related to prepayments at par of securities purchased at a premium.

All realized gains and losses related to the sales of available-for-sale investments are included in Other expense, net, in the accompanying condensed consolidated statements of income.

Unrealized Losses on Available-for-Sale Investments

The gross unrealized losses on the Company’s available-for-sale investments that are not deemed to be other-than-temporarily impaired as of March 31, 2014 and December 31, 2013 were $0.7 million and $0.6 million, respectively. Because the Company does not intend to sell any of its investments in an unrealized loss position and it is more likely than not that it will not be required to sell the securities before the recovery of its amortized cost basis, which may not occur until maturity, it does not consider the securities to be other-than-temporarily impaired.

Cost Method Investments

The Company held direct investments in privately-held companies of approximately $18.5 million and $24.3 million as of March 31, 2014 and December 31, 2013, respectively, which are accounted for based on the cost method and are included in Other assets in the accompanying condensed consolidated balance sheets. The Company periodically reviews these investments for impairment. If the Company determines that an other-than-temporary impairment has occurred, it will write-down the investment to its fair value. The Company determined one of its cost method investments was impaired and recorded a charge of $5.2 million during the first quarter of 2014 which was included in Other expense, net in the accompanying condensed consolidated statements of income.
