We did not record any allowances for credit losses to adjust the fair value of our marketable available-for-sale debt securities or gross realized gains or losses in the three months ended March 31, 2024 and 2023. Additionally, we did not record any realized gains or losses that were material to our condensed consolidated statements of income during the three months ended March 31, 2024 and 2023. As of March 31, 2024, we held marketable available-for-sale debt securities with a total fair value of $4.0 billion that were in unrealized loss positions totaling $19.1 million. Included in this amount were marketable available-for sale debt securities with a total fair value of $53.8 million and total unrealized loss of $0.4 million that had been in unrealized loss positions for greater than twelve months. We intend to hold these investments until maturity and do not expect to incur realized losses on these investments when they mature.
We record changes in the fair value of our investments in corporate equity securities to “Other (expense) income, net” in our condensed consolidated statements of income. During the three months ended March 31, 2024 and 2023, our net unrealized (losses) gains on corporate equity securities with readily determinable fair values held at the conclusion of each period were as follows:
