Note 3. Investments and Fair Value Measurement

Investments in debt securities

As of September 30, 2023, the Company held $3.0 million of investments in debt securities (which are included in the $7.6 million of cash and cash equivalents). For each of the three and six months ended September 30, 2023, there was $0.1 million 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 September 30, 2023 (in thousands):


	Amortized costs basis		Gross unrealized gains		Gross unrealized losses		Fair value

Investments in equity securities

For the six months ended September 30, 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 September 30, 2023, the fair value of investment in equity securities was zero, as a result of the liquidation of the shares by the underlying company during the six months ended September 30, 2023. As the investment in equity securities consists of common stock from active markets, the fair value is measured using level 1 inputs.
