[1] In the first quarter of 2025, we adopted accounting guidance that requires crypto assets to be measured at fair value, which resulted in an adjustment to reflect the difference between the carrying value of our holdings in crypto assets and their fair value as of the beginning of 2025. Crypto assets were not material to the Consolidated Financial Statements.
