Investments in Non-Affiliated Entities
Our investments in non-affiliated entities include marketable equity securities, which are publicly traded, and non-marketable equity securities, which are primarily investments in privately held companies.
Our marketable equity securities have readily determinable fair values and are recorded in long-term other assets on our Condensed Consolidated Balance Sheets at fair value with changes in fair value recorded in Other income and expense, net on our Condensed Consolidated Statements of Income. Marketable equity securities totaled $287 million and $225 million as of April 28, 2024 and January 28, 2024, respectively. The net unrealized and realized gains and losses of investments in marketable securities were not significant for the first quarter of fiscal years 2025 and 2024.
Our non-marketable equity securities are recorded in long-term other assets on our Condensed Consolidated Balance Sheets and valued under the measurement alternative. The carrying value of our non-marketable equity securities totaled $1.5 billion and $1.3 billion as of April 28, 2024 and January 28, 2024, respectively. Gains and losses on these investments, realized and unrealized, are recognized in Other income and expense, net on our Condensed Consolidated Statements of Income.
Adjustments to the carrying value of our non-marketable equity securities during the first quarter of fiscal years 2025 and 2024 were as follows:
