[1] | Corporate Treasury Commitments are measured using third party pricing.
[2] | Level III freestanding derivatives are valued using an option pricing model where the significant inputs include the expected return and expected volatility.
[3] | Other Investments includes Blackstone’s ownership of common stock of Corebridge. Following Corebridge’s IPO in September 2022, a quoted price for Corebridge’s common shares exists and as such the investment will be measured at fair value on a recurring basis as a Level I investment. Blackstone’s investment in Corebridge was previously valued as a Level III investment on a nonrecurring basis using the measurement alternative. See Note 4. “Investments — Other Investments” for additional details.
[4] | Equity Securities, Partnership and LLC Interest includes investments in investment funds. Prior period amounts have been reclassified to this presentation.
