Note 2 – Investments in Marketable Securities

Investments in marketable securities consist of debt securities and equity investments. We classify all of our debt securities as available-for-sale (“AFS”). Except when the fair value option is elected, AFS debt securities are recorded at fair value with unrealized gains or losses included in accumulated other comprehensive income (“AOCI”), net of applicable taxes. Interest income is recognized on an accrual basis and determined using the effective interest method. Realized gains and losses from sales of AFS debt securities are determined using the specific identification method or first in first out method. Dividend income, interest income, and realized gains and losses from the sales of AFS debt securities are included in Investment and other income (loss), net in our Consolidated Statements of Income.

We elected the fair value option for certain debt securities held within one of our investment portfolios for operational ease given the size and composition of this portfolio. All debt securities within this specific portfolio are recorded at fair value with changes in fair value included in Investment and other income (loss), net in our Consolidated Statements of Income. AFS debt securities for which the fair value option is elected are not subject to credit loss impairment evaluation. As of December 31, 2023 and March 31, 2023, we held AFS debt securities for which the fair value option was elected of $798 million and $770 million, respectively. The difference between the aggregate fair value and the aggregate unpaid principal balance of AFS debt securities for which the fair value option was elected was an unrealized loss of $58 million and $57 million as of December 31, 2023 and March 31, 2023, respectively.

All equity investments are recorded at fair value with changes in fair value included in Investment and other income (loss), net in our Consolidated Statements of Income. Realized gains and losses from sales of equity investments are determined using the first in first out method and are included in Investment and other income (loss), net in our Consolidated Statements of Income.

A portion of our equity investments are investments in funds that are privately placed and managed by an open-end investment management company (the “Trust”). If we elect to redeem shares, the Trust will normally redeem all shares for cash, but may, in unusual circumstances, redeem amounts exceeding the lesser of $250 thousand or 1 percent of the Trust’s asset value by payment in kind of securities held by the respective fund during any 90-day period.

We also invest in actively traded open-end mutual funds. Redemptions are subject to normal terms and conditions as described in each fund’s prospectus.

An allowance for credit losses is established when it is determined that a credit loss has occurred. As of December 31, 2023 and March 31, 2023, management determined that credit losses did not exist for securities in an unrealized loss position. This analysis considered a variety of factors including, but not limited to, performance indicators of the issuer, default rates, industry analyst reports, credit ratings, and other relevant information, which indicated that contractual cash flows are expected to occur.
