Investments in Available-for-Sale Securities | Investments in Available-for-Sale Securities We have invested in marketable debt securities, primarily investment-grade corporate bonds, preferred stock, and highly liquid U.S Treasury securities, which are held in the custody of a major financial institution. These securities are classified as available-for-sale and, accordingly, the unrealized gains and losses are recorded through other comprehensive income and loss. Marketable securities classified as available-for-sale securities are summarized below:
The aggregate fair value of investments with unrealized losses that had been owned for less than a year was $6,887 and $66,296 as of December 31, 2023 and 2022, respectively. The aggregate fair value of investments with unrealized losses that had been owned for more than one year was $21,543 and $64,723 as of December 31, 2023 and 2022, respectively. Available-for-sale investments outstanding as of December 31, 2023, classified as marketable securities in our consolidated balance sheets, have maturity dates ranging from the first quarter of 2024 through the second quarter of 2026. The fair value of marketable securities as of December 31, 2023 with maturities within one year and one to five years are $12,849 and $20,003, respectively. We classify available-for-sale investments as current based on the nature of the investments and their availability to provide cash for use in current operations, if needed.
