The amortized cost and fair value of investments available for sale at December 31, 2023, by contractual maturity, are shown below. Expected maturities will differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties. Because most U.S. agency mortgage-backed securities, residential and commercial mortgage securities and asset-backed securities provide for periodic payments throughout their lives, they are listed below in separate categories.

At December 31, 2023 and 2022, we held 2,256 and 2,578 individual investment securities, respectively, that were in an unrealized loss position. We assess our intent to sell these securities and whether we will be required to sell these securities before the recovery of their amortized cost basis when determining whether to record an impairment on the securities in an unrealized loss position. In assessing whether the decline in the fair value at December 31, 2023 of any of these securities resulted from a credit loss or other factors, we made inquiries of our investment managers to determine that each issuer was current on its scheduled interest and principal payments. We reviewed the credit rating of these securities noting that 98% of the securities at December 31, 2023 had investment-grade ratings. We concluded that gross unrealized losses noted above were primarily associated with the changes in interest rates subsequent to purchase rather than due to credit impairment. We recorded impairments of $0.2 million and $12.7 million in the years ended December 31, 2023 and 2022, respectively. The impairments resulted from our intent to sell these securities subsequent to a reporting date. There were no impairments in the year ended December 31, 2021.

The Company's other invested assets at December 31, 2023 and December 31, 2022 totaled $277.2 million and $257.9 million, respectively. Other invested assets are principally comprised of limited partnership interests which are generally accounted for under the equity method or fair value using net asset value (or its equivalent) as a practical expedient. Our proportionate share of earnings or losses or changes in fair value are reported in income from other invested assets on the consolidated statements of comprehensive income. For entities accounted for under the equity method that follow industry-specific guidance for investment companies, our proportionate share of earnings or losses includes changes in the fair value of the underlying assets of these entities. Due to the timing of receiving financial information from these partnerships, the results are generally reported on a one month or quarter lag.

Through June 30, 2021, unrealized gains and losses reported by these entities were included in other comprehensive income (“OCI”). Subsequent to June 30, 2021, management concluded that unrealized gains and losses on these investments should be reflected in earnings rather than OCI. Income from other invested assets for the year ended December 31, 2021 includes $7.6 million of net unrealized gains that were accumulated in OCI at December 31, 2020.

Other invested assets that are accounted for at fair value using the net asset value (or its equivalent) as a practical expedient totaled $137.8 million as of December 31, 2023. The majority of these investments were in limited partnerships invested in real estate or consumer credit. At December 31, 2023, maximum future funding commitments were $47.7 million. For limited partnership investments that have a contractual expiration date, we expect the liquidation of the underlying assets to occur over the next two to nine years. For certain of these investments, the Company does not have the contractual option to redeem but receives distributions based on the liquidation of the underlying assets. In addition, the Company generally does not have the ability to sell or transfer these investments without the consent from the general partner of individual limited partnerships.

The fair value of investments deposited with insurance regulatory authorities to meet statutory requirements was $9.2 million at December 31, 2023 and $9.1 million at December 31, 2022. In connection with its insurance and reinsurance activities, Essent Re is required to maintain assets in trusts for the benefit of its contractual counterparties. The fair value of the investments on deposit in these trusts was $1,060.0 million at December 31, 2023 and $972.4 million at December 31, 2022. Essent Guaranty is required to maintain assets on deposit in connection with its fully collateralized reinsurance agreements (see Note 5). The fair value of the assets on deposit was $5.1 million at December 31, 2023 and $8.6 million at December 31, 2022. Essent Guaranty is also required to maintain assets on deposit for the benefit of the sponsor of a fixed income investment commitment. The fair value of the assets on deposit was $9.2 million at December 31, 2023 and $9.1 million at December 31, 2022.
