Reserve Release Pressure After a Severity Shock
Cedar Valley Insurance is a regional auto carrier with $480 million of net written premium. At the 2024 reserve committee, the CFO notes that the 2023 bodily injury accident year has 1,200 reported claims, 480 still open, and an average case reserve of $18,500. Paid losses to date are $9.4 million, and IBNR is carried at $6.2 million while the actuary's central IBNR estimate is $8.9 million. The gap arose after an appellate ruling changed the treatment of noneconomic damages; the actuary raised severity by 12% but kept frequency flat because reported counts are 6% below plan. The CFO wants to release $2.0 million of IBNR to offset a projected underwriting loss, arguing that lower frequency will offset severity. The chief actuary is on leave. The board meets in two weeks and asks for a recommendation.
1. Assess whether releasing $2.0 million of IBNR is supportable. Show your reasoning and the key numbers.

The release is not supportable on the stated facts. Carried losses are paid of $9.4m plus open case reserves of 480 × $18,500 = $8.88m plus IBNR of $6.2m, or $24.48m. The central estimate is $9.4m + $8.88m + $8.9m = $27.18m, so the carried position is already $2.7m below central. A $2.0m release would take IBNR to $4.2m, roughly 47% below the actuary's central estimate, and total carried losses to $22.48m, about $4.7m below central.
The case reserves also look stale. If the 12% severity shift applies to open claims, indicated case reserves rise by about $1.07m to $9.95m. The 6% frequency shortfall does not automatically offset this: frequency is already reflected in reported counts, while the severity ruling affects the tail of large claims and may still be developing. The absence of the chief actuary removes the person best placed to sign off on a change in estimate. Recommendation: reject the release, hold at least the central estimate, and obtain a documented actuarial range before the board meeting.
2. What governance and operational controls should the reserve committee apply before the board meeting?
Read the worked answer
The committee should require a written actuarial memo that separates frequency and severity assumptions, shows the central estimate and range, and tests sensitivity to the appellate ruling. It should reconcile open case reserves claim by claim above a materiality threshold, review large-loss development, and test IBNR for late reporting. The committee should minute that any release must be supported by credible evidence, not by an earnings target, and should disclose the $2.7m gap and the CFO's request to the board. Operationally, it should place a moratorium on reserve releases for the 2023 accident year until the chief actuary returns or an independent peer review is completed, and it should track case reserve adequacy monthly. This preserves independence and avoids a decision that could later require a prior-period adjustment.
3. Recommend two claims-operations actions that would improve reserve reliability over the next two quarters.
Read the worked answer
First, implement early severity triage for bodily injury claims with noneconomic damage exposure, using a checklist tied to the appellate ruling and assigning senior adjusters above a set reserve threshold. This addresses the stale average case reserve by forcing claim-level evaluation rather than relying on a blended average. Second, shorten the reporting lag for IBNR by monitoring late-reported claims and attorney-representation rates weekly, and reconcile the claims system to the actuarial database monthly. Neither action fixes the reserve gap immediately, but both reduce the chance that the next estimate is built on outdated case reserves and unobserved severity. The committee should require the actions to be owned by the claims vice president with dated milestones.
