The NAIC’s Casualty Actuarial and Statistical (C) Task Force is scheduled to meet Monday, November 16, 2026, from 9:30 to 11:00 a.m. at the Fall National Meeting in Dallas, which runs November 14 to 17 in a hybrid format, per Willkie’s preview. Item 2A on its draft agenda is to consider adopting the reports of the Actuarial Opinion (C) Working Group, chaired by Miriam Fisk of Texas. Nothing in Dallas is expected to rewrite the reserve opinion. The substance was settled earlier: the meeting materials show the working group adopted the 2026 Regulatory Guidance on August 27 after a 37-day exposure that drew one official comment, then adopted edits to the state analyst’s opinion worksheet by an e-vote that concluded September 24.
So this is a preview of a ratification, and the useful question for a captive board is what the year-end 2026 opinion now has to contain.
What the 2026 guidance actually changes
The final 2026 Regulatory Guidance lists seven changes to the property and casualty opinion instructions. Six of them, grouped into four themes, reach an ordinary captive or risk retention group (RRG) reserve study:
- Reliance on another’s work. If the Appointed Actuary uses an analysis not produced under their direction for a material portion of the reserves, the Actuarial Report must now show the dollar amount of reserves covered, the percentage of total opined reserves that represents, whether and how far the actuary reviewed the underlying methods, assumptions, and arithmetic, and the conclusions of that review.
- Schedule P reconciliation. The report must reconcile the data the actuary actually used, not merely the data the company supplied. The guidance says the actuary should demonstrate that “data was neither created nor destroyed” during the analysis. If someone else performed the reconciliation, the report must name them and confirm the actuary reviewed it for reasonableness.
- Long-duration unearned premium. Unearned premium reserves for P&C long-duration contracts go on Exhibit A regardless of materiality, with clarifying comments when the actuary deems them immaterial and is not opining on them.
- Exhibit B housekeeping. The pools and associations disclosure (Line 10) is removed, and Line 11, the extended reporting reserve for claims-made contracts offering free tail coverage on death, disability, or retirement, is clarified to cover every professional liability line, not only medical.
The seventh updates the “Accepted Actuarial Designation” definition for the new Society of Actuaries pathway. The exposed redline of the analyst worksheet, 12 pages with 38 drafter comments, conforms the checklist state analysts use to those instructions. It also deletes “and principles” from the test of whether reserves follow accepted standards, because, in the drafter’s words, “the CAS reserving principles have been rescinded.” Actuary.info’s read of the worksheet walks through that deletion and flags that the relocated opinion-type branch still carries the old phrase, which the worksheet text confirms.
Who it affects
RRGs first. The NAIC’s accreditation standards carve captives out of the Part A requirements with one exception: multi-state RRGs organized as captives. For those, states must require an annual opinion on loss and loss adjustment expense reserves “by a qualified actuary or specialist” for all domestic RRGs, and annual and quarterly statement filings with the NAIC. The NAIC’s RRG overview describes the annual filing as the P&C annual statement blank, an audited financial statement, and a reserve opinion, with regulators following the Financial Analysis Handbook. That is the handbook the worksheet lives in.
Single-parent and group captives are not directly bound. But domiciles borrow. Tennessee’s proposed captive rewrite would require a filed annual opinion from every captive (our coverage), and Utah has already made the actuarial reserve estimate a capital input (our coverage). When a captive regulator needs a template for what a reserve opinion and report should contain, this document is the one on the shelf. The guidance itself names RRGs as a company structure where the signing actuary’s relevant experience should be documented for the board.
The reserve mechanism
None of this moves a loss development factor. The lever is disclosure of where the number came from, and it bites hardest on structures where part of the reserve is set by someone the captive’s actuary does not direct. Think of a group captive whose fronted layer is reserved by the carrier’s actuaries, or an RRG whose assumed pool share comes with the pool’s own estimate. Until now the opinion had to name that person. The 2026 instructions keep that and add the size to the report: dollars and percentage. A reviewing regulator can now see at a glance whether the opinion rests 5% or 50% on work the signer did not perform, and whether the signer checked it. Our explainer on fronting, reinsurance, and net versus gross reserves covers why those layers are often reserved separately, and the fronting collateral squeeze shows the same dependence from the collateral side.
Three numeric tests in the guidance and worksheet are worth sizing against your own balance sheet:
- Persistent adverse development. The worksheet asks whether one-year adverse development exceeded 5% of prior-year surplus in three or more of the past five calendar years. If so, the confidential Actuarial Opinion Summary must explain the reserve elements or management decisions responsible. Illustration (hypothetical): an RRG with $8 million of surplus trips the annual test on $400,000 of adverse development.
- Risk of material adverse deviation. The guidance says such risk “should likely exist when the sum of the materiality standard plus the carried reserves is within the range of reasonable estimates.” Illustration (hypothetical): carried reserves of $10.0 million, a $1.0 million materiality standard, and a reasonable range topping out at $11.5 million gives $11.0 million, inside the range, so a “no” answer needs explicit support.
- Expected loss ratios. The guidance states that phrases such as “actuarial judgment” are “not sufficient” support and that historical loss ratios “have little value” if rate actions or program revisions have changed premium adequacy. For young RRG accident years reserved on the expected loss ratio method, that is a direct documentation demand.
The worksheet also restates the retention rule: the Actuarial Report and work papers stay available for regulatory examination for seven years.
Where this shows up in your reserves
Open the last Actuarial Report, not just the opinion. Look for a reconciliation exhibit that maps the actuary’s analysis segments to Schedule P lines, on both a net and a direct and assumed basis. Then look for any reserve component credited to another firm, a fronting carrier, or a pool. If the report does not state its dollar amount and share of the total, the year-end 2026 version must. Board members can line this up against the annual reserve report to the captive board; the guidance says the board should hear what amount of adverse deviation the actuary judges material. RRG boards can also use our group captive and RRG IBNR guide.
Our call
Expect the November 16 session to adopt the working group’s reports without changes to the P&C guidance, which was finalized in August. The worksheet was referred to the Financial Analysis Solvency Tools (E) Working Group “for consideration,” so its final handbook wording could still shift.
Our directional read: the 2026 changes are neutral for carried reserves and negative for thin documentation. The first place it shows is year-end 2026 RRG opinions, and the most exposed are RRGs and group captives with fronted or pooled layers reserved by someone else, where the reliance percentage has never been written down. We expect that percentage to become a standing regulator question in 2027 analysis cycles, and captive domiciles that adopt filed-opinion rules, as Tennessee proposes and as Vermont’s recent RRG tightening suggests is the direction, to lift this language rather than write their own.
What this means for your next review
Ask your actuary three things before the year-end study starts: what share of reserves relies on analysis they did not direct, and what review they will perform; whether the data reconciliation ties their working triangles, not just the claim system extract, to the financial statement; and where carried reserves sit in the range relative to the materiality standard.
