(1) Time deposits excluded from fair value measurements.

Our investment portfolio consists of both corporate and government securities that have a maximum maturity of three years . The longer the duration of these securities, the more susceptible they are to changes in market interest rates and bond yields. As yields increase, those securities with a lower yield-at-cost show a mark-to-market unrealized loss. Most of our unrealized losses are due to changes in market interest rates and bond yields. We believe that we have the ability to realize the full value of all of these investments upon maturity. As of 2019年12月31日 , we had 81 investments in an unrealized loss position. The following table summarizes the fair value and gross unrealized losses of our investments that were in an unrealized loss position as of the date indicated below, 6830万美元其中的连续损失位置持续了12个月或更长时间：



As of December 31, 2019 (In thousands)	公平的价值		Gross 未实现损失
公司债务证券	$	88,354	$	（32	)
Municipal securities	3,671		（3		)
美国政府机构证券	37,246		(13		)
美国国库券	87,526		（37		)
全部的	$	216,797	$	（85	)

The contractual maturities of securities classified as available-for-sale, regardless of their classification on our Condensed Consolidated Balance Sheets, as of the date indicated below were as follows:



As of December 31, 2019 (In thousands)	摊余成本		公平的价值
在一年之内到期	$	386,442	$	386,617
三年后到期	350,372		351,041
	$	736,814	$	737,658

Actual maturities may differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties. Realized gains and losses on available-for-sale securities for the three and 六几个月结束了 2019年12月31日和 2018 是非物质的。
