An insurer collects premium today and pays claims for years afterward. The unpaid claim estimate is management's best guess at that future bill. If the guess is wrong, everyone who trusts the balance sheet inherits the error.
The unpaid claim estimate is what an estimation technique produces for claims that have occurred but are not yet fully paid. It has five components: case outstanding (the case reserves adjusters set on known claims), a provision for future development on known claims, an estimate for reopened claims, pure IBNR (the provision for claims that have occurred but have not yet been reported), and claims in transit (claims reported but not yet recorded). The last four together form the broad definition of IBNR; pure IBNR is only the unreported piece.
KEY: Do not equate the estimate with the booked figure. The unpaid claim estimate is what a technique produces, and it can differ by method and by valuation date. The carried reserve is the amount management actually books in the financial statement.
Common mistakes
- Thinking redundancy is harmless. Padding is still a wrong estimate. It understates income and surplus by the amount of the redundancy, misleading investors.
- Confusing the direction of the surplus effect. Deficient reserves understate the liability, which overstates surplus and income, not understates them.
- Ignoring financial-statement consequences. A reserve deficiency understates liabilities and overstates reported financial strength, which can delay corrective action.
Bottom line
- The unpaid claim estimate has five parts: case outstanding, future development on known claims, reopened claims, pure IBNR, and claims in transit; the last four together form broad IBNR while pure IBNR is only the unreported piece.
- The unpaid claim estimate is what a technique produces; the carried reserve is what management books, and this lesson's stakes are about the carried reserve being wrong.
- The reserve is usually the single largest liability on a property-casualty balance sheet, so an error in it passes straight into reported surplus and income.
- Deficient (understated) reserves overstate surplus and income, mask inadequate rates, delay corrective action, and raise insolvency risk.
Exam shortcut
For a reserve error, trace the effect on liabilities, reported financial strength, and management decisions. Friedland emphasizes pricing, underwriting, strategic, investment, and regulatory consequences. Memorize the sign map: deficient reserves overstate surplus and income and understate rates; redundant reserves do the opposite. If a question asks which error flatters the financials, the answer is deficiency.
