As most people involved in insurance and reinsurance know, historical loss experience is key to underwriting and pricing reinsurance coverage. One would think the same would be true for investors in a reinsurance company. In a recent case, a federal appeals court addressed an appeal of a summary judgment motion in favor of the reinsurer against investors in a securities fraud case focused on the omission of historical loss reserves in the reinsurer’s public filings.

Securities Litigation, No. 24:1118 (3rd Cir. Aug. 20, 2025), the Third Circuit Court of Appeals reversed the district court’s order granting summary judgment dismissing a securities fraud case. The case focused on whether the reinsurer’s knowledge of historical loss reserves of certain business assumed from its ceding insurer and its omission to disclose that information in public filings was material under the federal securities laws.
Others have digested and analyzed this case from a securities law and fraud perspective. I won’t do that here (I am not a securities lawyer). My focus is on the loss reserve and reinsurance part of the case. What was involved here was historical loss reserve information about a large segment of the reinsurer’s assumed liabilities from a particular ceding insurer and whether that information should have been disclosed in public filings.
The opinion has several interesting observations. For example, the court described reinsurance and loss reserves and also discussed the complexities of actuarial analysis.
Reinsurance is the business of insuring insurance companies. Therefore, just like any other insurance company, reinsurers have to set aside funds to pay out future claims. These set-aside funds, known as “loss reserves,” are the product of “an insurer’s actuarial judgment” and are generally calculated based on many factors. (citation omitted). Because reserves represent predicted losses, they are effectively removed from an insurer’s operating income and treated as liabilities in financial reports. A company that sets its loss reserves too low effectively understates its liabilities, thus inflating its perceived financial strength.
In reframing and answering the legal question, the court said:
The critical question is whether the omitted historical loss data was material. Reading the record in the light most favorable to [the plaintiff], a reasonable factfinder could find that it was.
The key was that the evidence was sufficient to show that the reinsurer knew and considered the adverse loss data, but in calculating its reserves for public filing purposes chose a different reserve pick. The court pointed out that the cedent’s business was the reinsurer’s largest client relationship, that the reinsurer had access to the negative historical data, and that historical loss data was an important part of the reinsurer’s loss reserve estimation process.
. . . viewed holistically, the evidence in the current record provides the full
“context” necessary to raise a genuine issue of material fact as to whether the omission of [the ceding company’]s historical loss data was material. There is evidence that [the reinsurer’s] business depended on [the cedent} and that historical trends were one of the most significant considerations when [the reinsurer] set reserves.
Essentially, the court rejected the argument that because the reinsurer considered the historical loss data and calculated its reserves differently, there was no actionable case. The court reversed summary judgment and allowed discovery to proceed at the district court level.
