American International Group
American International Group was founded by Cornelius Vander Starr as a general insurance agency in Shanghai, China, in 1919. Peter Zaffino now runs the firm as Chairman and CEO, having steered the company through its post-crisis recovery and a complex separation of its life and retirement unit into Corebridge Financial, in which Nippon Life Insurance Company acquired a 21.6% stake in 2024 (per Reuters, 2024). The company remains headquartered at 1271 Avenue of the Americas in New York. AIG's general account portfolio spans several major asset classes, deploying capital through both internal teams and external manager relationships. Real estate has long been a pillar — the firm holds a multifamily apartment portfolio concentrated in New Jersey, Pennsylvania, and Delaware, alongside a US industrial portfolio in southeast markets including Virginia, Georgia, North Carolina, and Tennessee. The firm also maintains a US multifamily investment platform and operates a corporate aviation fleet of Gulfstream aircraft. On the alternatives side, AIG participates in private credit, infrastructure equity, and hedge fund allocations, often through co-investment and direct secondaries structures. Strategic relationships deepen its deployment reach — Peter Zaffino has a well-cited partnership with Blackstone CEO Stephen Schwarzman, whose firm manages substantial insurance capital on behalf of AIG. The parent company's pension plan, established in 1985, operates as a noncontributory defined benefit plan. AIG executives engage actively with policy and governance groups including the Business Roundtable and the Committee for Economic Development. The firm's non-insurance assets include the AIG Corporate Art Collection in New York. In mid-2026, Peter Zaffino is expected to transition from Chairman and CEO to Executive Chair (per the firm's official communications, 2024). The AIG Foundation channels the firm's philanthropic commitments. AIG's structural differentiator is the dual engine of a rated insurance operating company and a general account portfolio with direct access to private markets sourcing through its senior leadership's external relationships. Very few insurance companies run an alternatives program this directly integrated with CEO-level strategic partnerships — the Blackstone relationship and the Nippon Life cross-holding in Corebridge are not typical asset-manager mandates but deeply embedded capital relationships that give AIG co-investment visibility most insurers never access.

Frequently asked questions
Who controls capital allocation decisions at AIG's general account?
Capital allocation is governed by AIG's internal investment committee, which reports through the CFO and CEO to the board. Peter Zaffino, as Chairman and CEO, has been the most visible figure shaping the firm's strategic asset relationships, including the deep tie with Blackstone that places the alternative manager as a primary investment partner for AIG's insurance float.
What is AIG's relationship with Blackstone?
AIG and Blackstone have a long-term strategic relationship that extends well beyond a standard limited partner allocation. Blackstone CEO Stephen Schwarzman has been cited as a direct business partner. The asset manager handles a significant share of AIG's insurance-linked and general account alternatives exposure, a relationship that deepened as AIG exited the life and retirement business through Corebridge Financial.
How large is AIG's real estate portfolio?
AIG owns and operates direct real estate holdings concentrated in US multifamily apartments across New Jersey, Pennsylvania, and Delaware, as well as an industrial portfolio in southeastern states including Virginia, Georgia, North Carolina, and Tennessee. The firm also maintains a US multifamily investment platform. AIG does not publicly disclose the aggregate carrying value of its real estate assets.
Does AIG operate any philanthropic vehicles?
Yes, AIG maintains the AIG Foundation as its principal philanthropic structure. The foundation's activities sit separately from the insurance operating companies and the general account portfolio, though they are funded by company-directed charitable contributions.
What happened to AIG's structured credit exposure after the 2008 crisis?
AIG unwound the vast majority of its crisis-era structured credit exposures, including the Financial Products division that had written credit default swaps on mortgage-backed securities and collateralized debt obligations. The firm repaid the $182 billion federal bailout in full by 2012, including a positive return to the US Treasury. The modern asset portfolio bears essentially no resemblance to the pre-crisis composition.
Is AIG still a globally active direct investor, or primarily a fund-of-funds allocator?
AIG operates as both a direct investor and a fund allocator. The firm has historically participated in co-investments, direct secondaries, and hybrid structures alongside fund commitments. Its real estate and aviation assets are held directly. However, the firm does not publicly market itself as a direct private equity investor in the style of a family office or sovereign wealth fund.
What is Corebridge Financial, and how is it connected to AIG?
Corebridge Financial is the life insurance and retirement services business that AIG separated into an independent publicly traded company. In May 2024, Nippon Life Insurance Company acquired a 21.6% stake in Corebridge from AIG (per Reuters, 2024). AIG retained a significant remaining ownership at the time of the transaction, though the relationship has shifted toward arm's-length public-market governance.
