Claims Reserves: The Number Set Before Anything Is Paid

An insurer assigns a cost to a claim as soon as it is notified, long before anything is paid. That estimate is the reserve, and it behaves like a payment in most systems.

What a reserve is for

Insurers must know what they owe in order to hold sufficient funds and report accurately. Since claims take time to settle, unpaid liabilities must be estimated.

Each open claim carries a case reserve, set by the handler using the known facts, and revised as evidence arrives. Together they form a large part of an insurer's balance sheet.

Regulators require this because an insurer that understates its liabilities appears solvent while actually being unable to pay.

Why the first number is often large

Early reserves are set cautiously, because the worst case cannot yet be excluded. An injury claim with an unclear prognosis is reserved for a serious outcome until proven otherwise.

Under-reserving and then increasing later is more disruptive than starting high and releasing, so the incentives push towards caution.

This produces the situation where a claim eventually settling for a modest sum sat on the books at a much larger figure for a year or more.

The effect on the policyholder's renewal

Renewal pricing reads the claims record, and an open claim shows its reserve rather than a final cost. The policyholder is priced against the estimate.

This is why a premium can rise sharply after a non-fault claim that has not yet been recovered, and can fall again once the file closes.

Asking whether an open claim has been closed and at what figure before accepting a renewal is a practical step that is rarely taken.

Recovery and the reserve

Where an insurer expects to recover its outlay from another party, the claim may still be reserved gross until recovery is achieved.

Until the file is closed as a successful recovery, the claim can appear on shared industry data in a form that other underwriters read as a cost.

Chasing an insurer to close and correctly categorise a recovered claim is therefore worth more than it appears.

Where reserving becomes visible

Reserves explain apparent inconsistencies: an insurer resisting a modest settlement, or a broker reporting a claims cost far above what was paid.

They also explain why long-tail classes such as injury and liability are priced conservatively, since the eventual cost is unknown for years.

Reserving practice, data-sharing conventions and renewal rating methods vary by insurer and jurisdiction and change over time. The insurer's own records determine what other underwriters see.
