🔬 '''Independent actuarial review''' is a comprehensive examination of an insurer's reserving, pricing, or other actuarial work product conducted by an [[Definition:Actuary | actuary]] or actuarial firm that operates independently of the subject company's management. While closely related to the [[Definition:Independent actuarial opinion | independent actuarial opinion]], a review is generally broader in scope and more detailed in execution: it may cover the entire reserving methodology, the adequacy of [[Definition:Rate filing | rate filings]], the quality of underlying data, the appropriateness of assumptions, and the governance processes surrounding actuarial functions — not merely the bottom-line reserve figure. Independent actuarial reviews are commissioned by boards, audit committees, [[Definition:Rating agency | rating agencies]], regulators, or transaction counterparties seeking a deeper diagnostic than a formal opinion alone can provide.

⚙️ The reviewing actuary typically reconstructs key analyses from the ground up, replicating or challenging the company's [[Definition:Loss development triangle | development triangles]], [[Definition:Incurred but not reported analysis (IBNR analysis) | IBNR projections]], and selected actuarial methods. The review extends to testing assumptions such as [[Definition:Loss trend | loss trends]], [[Definition:Claim frequency | frequency]] patterns, [[Definition:Severity trend | severity inflation]], and the treatment of large or [[Definition:Catastrophe loss | catastrophe losses]]. In a [[Definition:Due diligence | due diligence]] setting — for example, when a [[Definition:Private equity | private equity]] firm evaluates an insurance platform acquisition — the independent actuarial review becomes one of the most consequential workstreams, often spanning multiple lines of business and multiple accident years. The deliverable is usually a detailed report with a range of [[Definition:Ultimate loss | ultimate loss]] estimates, identification of key sensitivities, and commentary on the quality of the actuarial infrastructure. In markets governed by [[Definition:IFRS 17 | IFRS 17]], the review may also evaluate the appropriateness of the insurer's [[Definition:Risk adjustment | risk adjustment]] calibration and [[Definition:Contractual service margin (CSM) | contractual service margin]] calculations.

💡 Commissioning an independent actuarial review signals a commitment to rigorous financial governance — a message that resonates with regulators, reinsurers, and capital providers alike. For boards of directors who may lack actuarial expertise, the review serves as an essential second line of defense, highlighting areas where management's estimates may be optimistic or where methodological improvements are needed. In post-merger integration, the review helps the acquiring organization reconcile the target's reserving conventions with its own and establish a unified approach going forward. Increasingly, [[Definition:Insurtech | insurtech]] ventures and [[Definition:Managing general agent (MGA) | MGAs]] seeking capacity from [[Definition:Insurance carrier | carriers]] or [[Definition:Reinsurance | reinsurers]] are asked to submit to an independent actuarial review of their pricing models and early loss experience, underscoring the role of these reviews as a gatekeeping mechanism for market access.
