Due Diligence: Actuarial Role in Insurance M&A

Actuarial Due Diligence Scope

Actuarial due diligence in insurance M&A involves a thorough assessment of the target company's reserves, pricing adequacy, and risk profile. The actuary reviews loss development triangles, reserve methodologies, reinsurance arrangements, and key assumptions. The goal is to identify whether carried reserves are adequate, redundant, or deficient, as reserve adjustments directly affect the transaction price. Due diligence also evaluates the sustainability of current pricing, the quality of the underwriting portfolio, and exposure to emerging risks.

Key Findings and Impact

Common due diligence findings include reserve deficiencies in long-tail casualty lines, pricing inadequacy in competitive segments, latent exposure to environmental or mass tort claims, and data quality issues that limit analytical confidence. Material findings can change the transaction price by millions of dollars, alter deal structure (such as adding reserve holdbacks or earn-out provisions), or even cause deals to collapse. Actuarial due diligence reports are relied upon by boards of directors, investors, regulators, and rating agencies evaluating the proposed transaction.
