Credit rating agency AM Best has assigned American International Reinsurance Global (AIRG), a Bermuda-based AIG subsidiary, a Financial Strength Rating of A (Excellent) and a Long-Term Issuer Credit Rating of “a+” (Excellent), and assigned a positive outlook.

The ratings of AIRG also reflect the company’s role as a reinsurer of affiliated international business, and the reinsurance, liquidity and other explicit and implicit support provided by other AIG entities. AIRG is expected to start assuming affiliated reinsurance in 2026.
The positive outlooks are in line with the current outlook for AIG and its subsidiaries.
AIRG serves as an international reinsurance vehicle, meaning its primary purpose is to insure the risks of AIG’s own international insurance businesses rather than selling reinsurance to third-party companies.
The creation of this entity appears to be part of AIG’s broader strategy to optimise its capital structure. By centralising international reinsurance in a Bermuda-based entity, AIG can more efficiently manage capital, liquidity, and risk across its global operations.
