Investment Securities

The Company's investment securities consist of available-for-sale asset-backed securities with contractual maturities of twelve months or less. These securities are stated at fair value within current assets on the Company's balance sheet. Realized gains and losses on sales of investments, if any, are reflected in nonoperating income (expense) in the statements of operations. Unrealized gains and losses on investment securities are reflected as a component of accumulated other comprehensive income, (AOCI).

During the third quarter of 2016, the Company invested $100 million in available-for-sale investment securities, earning interest income at a weighted-average fixed rate of approximately 1.2%. For the three and nine months ended September 30, 2016, an unrealized gain of $4 thousand, net of deferred taxes of $3 thousand, was recorded within AOCI related to these investment securities. The Company has not recognized any realized gains or losses related to these securities as the Company has not transacted any sales of these securities.
