Argentina's Superintendency of Insurance approved a framework allowing insurers to use alternative internal models to calculate incurred but not reported claims reserves. The framework applies from financial statements closing on June 30, 2026, and requires models to meet the authority's technical and actuarial standards. Insurers must demonstrate reserve adequacy every six months through a sufficiency test and a report signed by an external actuary. The framework also provides for gradual amortization of differences from the general methodology and progressive reserve releases based on results.
