AES Ohio established a Master Trust to hold assets that could be used for the benefit of employees participating in employee benefit plans. These assets are not used for general operating purposes and are primarily comprised of open-ended mutual funds, which are valued using the net asset value per unit. These assets are recorded at fair value and classified as equity investments in Other non-current assets on the Condensed Consolidated Balance Sheets. Net unrealized gains / (losses) related to equity investments still held as of September 30, 2026 and 2025 are as follows:
