Total investments related to long-term incentive compensation obligations of $40.4 million and $54.1 million as of September 30, 2026 and December 31, 2025, respectively, consist of company-sponsored mutual funds and hedge funds. For long-term incentive compensation awards granted before 2009, we typically made investments in company-sponsored mutual funds and hedge funds that were notionally elected by plan participants and maintained them (and continue to maintain them) in a consolidated rabbi trust or separate custodial account. The rabbi trust and custodial account enable us
to hold such investments separate from our other assets for the purpose of settling our obligations to participants. The investments held in the rabbi trust and custodial account remain available to the general creditors of AB.

The underlying investments of hedge funds in which we invest include long and short positions in equity securities, fixed income securities (including various agency and non-agency asset-based securities), currencies, commodities and derivatives (including various swaps and forward contracts). These investments are valued at quoted market prices or, where quoted market prices are not available, are fair valued based on the pricing policies and procedures of the underlying funds.

We allocate seed capital to our investment teams to help develop new products and services for our clients. A portion of our seed capital trading investments are equity and fixed income products, primarily in the form of separately-managed account portfolios, U.S. mutual funds, Luxembourg funds, Japanese investment trust management funds or Delaware business trusts. We also may allocate seed capital to investments in private equity funds and other private alternative investment vehicles. Regarding our seed capital investments, the amounts above reflect those funds in which we are not the primary beneficiary of a VIE or hold a controlling financial interest in a VOE. See Note 14, Consolidated Company-Sponsored Investment Funds, for a description of the seed capital investments that we consolidate. As of September 30, 2026 and December 31, 2025, our total seed capital investments were $339.3 million and $372.1 million, respectively. Seed capital investments in unconsolidated company-sponsored investment funds are valued using published net asset values or non-published net asset values if they are not listed on an active exchange but have net asset values that are comparable to funds with published net asset values and have no redemption restrictions.

Investment in the joint venture on the condensed consolidated statement of financial condition is accounted for under the equity method of accounting.

During the fourth quarter of 2024, we entered into a non-exclusive agreement with Reinsurance Group of America, Incorporated (“RGA”) under which we committed to invest $100.0 million in a reinsurance sidecar vehicle sponsored by RGA and focused on the U.S. asset-intensive reinsurance market. During the three months ended September 30, 2026, we funded $99.9 million of this commitment. As of September 30, 2026, we have funded our total commitment of $100.0 million. The investment on the condensed consolidated statement of financial condition is accounted for under the equity method of accounting, recorded on a quarter lag and represents an approximate 20.9% equity method investment in the RGA sidecar.

The portion of unrealized gains (losses) related to equity securities, as defined by ASC 321-10, held as of September 30, 2026 and 2025 were as follows:
