Investments and Fair Value Measurement

Note 3. Investments and Fair Value Measurement

Investments in debt securities

As of December 31, 2023, the Company held $2.0 million of investments in debt securities (which are included in the $5.3 million of cash and cash equivalents). For the three and nine months ended December 31, 2023, there was less than $0.1 million and $0.1 million, respectively, of interest income related to the investments in debt securities. As the investments in debt securities consist of U.S. Treasury bills from active markets, the fair value is measured using level 1 inputs.

The following table summarizes the Company's investments in debt securities that are measured at fair value as of December 31, 2023 (in thousands):

Investments in equity securities

For the nine months ended December 31, 2023, there was $0.7 million of equity securities liquidated and less than a $0.1 million gain on the investment in equity securities. As of December 31, 2023, the fair value of investment in equity securities was zero, as a result of the liquidation of the shares by the underlying company on June 26, 2023. As the investment in equity securities consists of common stock from active markets, the fair value is measured using level 1 inputs.

The following table presents the activity for investments in equity securities measured at fair value for the nine months ended December 31, 2023 (in thousands):
