Definition:Reserve review
🔎 Reserve review is the formal process by which an insurer or reinsurer periodically reassesses the adequacy and accuracy of its loss reserves, typically conducted by internal reserving actuaries and supplemented by independent external opinions. Unlike the continuous day-to-day claims adjustments that occur at the file level, a reserve review takes a portfolio-wide view, analyzing trends across lines of business, accident years, and geographic segments to determine whether aggregate reserves remain appropriate.
📋 The review process usually follows a structured cycle — quarterly for management reporting, with a comprehensive annual exercise that feeds into statutory and GAAP financial statements. Actuaries apply multiple projection methods, compare results against benchmarks, and investigate segments where actual experience deviates from expectations. The output is typically a range of reasonable estimates alongside a recommended point estimate or best estimate. Management and the board then decide where within the range to set carried reserves, balancing financial strategy, regulatory requirements such as those from the NAIC, and rating agency expectations. In the Lloyd's market, syndicates undergo additional scrutiny through the Lloyd's reserving oversight process.
✅ Rigorous reserve reviews serve as a critical governance mechanism and a safeguard against surprises. They provide early detection of adverse reserve development, enabling timely corrective action — whether that means adjusting pricing, tightening underwriting guidelines, or purchasing additional reinsurance protection. For insurtech companies and MGAs building track records, transparent reserve reviews conducted by credentialed actuaries lend credibility with capacity providers and investors. Regulators may also mandate independent reviews for companies that exhibit signs of financial stress, making the practice both a best-practice discipline and a compliance requirement.
