Loss Reserving Triangle Memov0.1.2

A credentialed reserving actuary needs to review a workers compensation book at year-end using paid and incurred triangles split by state and NCCI classification. The skill guides intake, checks triangle shape and diagonals, develops LDFs and BF indications, and produces a draft memo with judgment log for the Appointed Actuary. The final booked reserves still require actuarial sign-off.

An actuarial analyst working under an FCAS uses the skill to re-evaluate a commercial auto liability program after a large-loss threshold change. The skill flags structural breaks in the data, supports Cape Cod and frequency-severity selections per segment, and reconciles indicated vs selected ultimates. The output is a DRAFT work paper, not a regulatory filing.

A reinsurance actuary prepares a loss reserve indication for an excess-of-loss treaty using ceded and net triangles by attachment point. The skill helps document cession structure, test sensitivity to large-loss assumptions, and build a peer-reviewable memo for treaty audit and pricing discussions. The tool does not opine on solvency or sign an SAO.

A captive actuary needs board-ready reserve indications for a captive general liability book. The skill leads structured intake, reviews data quality for exposure consistency and cat treatment, develops indicated ultimates, and produces a draft memo with an unresolved information log. The captive board uses the draft to support reserve decisions and audit discussions.

A consulting actuary performing merger and acquisition diligence applies the skill to legacy general liability and professional liability triangles. The skill documents segmentation, diagnostics, method selection, and sensitivity tables, and generates a draft memo suitable for the deal team and reviewing actuary. It never produces a signed SAO or regulatory filing.

P&C carriers need defensible reserve indications for statutory, GAAP, and management reporting. Reserving teams use the skill to standardize triangle diagnostics, method selection per segment, and peer-reviewable documentation before the Appointed Actuary signs the SAO.

Reinsurers and retrocessionaires analyze ceded and net loss triangles by treaty, layer, and attachment point. The skill supports XOL reserve indications, sensitivity testing, and audit-ready memos that feed pricing and capital decisions.

Consulting actuaries perform reserve reviews, M&A diligence, captive board support, and litigation engagements for multiple clients. The skill provides a repeatable work-paper structure and judgment log that speeds delivery while preserving reviewability.
