Statutory Accounting Principles (SAP)

Accounting rules prescribed by state regulators that emphasize solvency and policyholder protection; generally more conservative than GAAP, requiring immediate recognition of certain costs.

Related: Generally Accepted Accounting Principles (GAAP), NAIC Annual Statement, Actuarial opinion
Generally Accepted Accounting Principles (GAAP)

Common financial reporting framework emphasizing matching of revenues and expenses; insurers use it for public reporting, often producing different results from statutory accounting.

Written premium

Total premium charged on policies issued during a period, regardless of coverage period; it measures new business volume and drives cash collection.

Related: Earned premium, Expense ratio
Earned premium

Portion of written premium allocated to the coverage period that has elapsed; recognized as revenue as insurance protection is provided.

Related: Written premium, Unearned premium reserve, Loss ratio
Unearned premium reserve

Liability representing premium received for coverage not yet provided; it is earned over the remaining policy term and protects policyholders if coverage ends early.

Related: Earned premium, Premium deficiency reserve
Loss reserve

Estimate of unpaid amounts owed for claims that have occurred, including reported and unreported claims; a major liability and source of estimation uncertainty.

Related: Incurred but not reported (IBNR) reserve, Loss adjustment expense (LAE) reserve, Actuarial opinion
Incurred but not reported (IBNR) reserve

Provision for claims that have happened but have not yet been reported to the insurer; estimated using actuarial methods and historical reporting patterns.

Related: Loss reserve, Actuarial opinion
Loss adjustment expense (LAE) reserve

Funds set aside for costs of investigating, defending, and settling claims, separate from the claim payment itself; includes allocated and unallocated expenses.

Related: Loss reserve, Loss ratio
Deferred acquisition costs (DAC)

Under GAAP, capitalized costs of acquiring new business, such as commissions, amortized over the policy period; statutory accounting generally expenses them immediately.

Related: Generally Accepted Accounting Principles (GAAP), Expense ratio
Reinsurance recoverable

Amount an insurer expects to collect from reinsurers for ceded losses and expenses; an asset that is subject to credit risk and may be reduced for uncollectible balances.

Related: Reinsurance, Risk-based capital (RBC)
Premium deficiency reserve

Liability recognized when expected future claim costs and expenses exceed unearned premium plus anticipated investment income; signals that a block of business is unprofitable.

Related: Unearned premium reserve, Loss reserve
Policyholder dividend

Portion of surplus or earnings returned to participating policyholders; treated as an expense or distribution depending on accounting framework and declared by the board.

Related: Policyholders' surplus
Salvage and subrogation

Recoveries from selling damaged property or pursuing third parties responsible for a loss; these reduce net claim costs and are estimated in loss reserves.

Related: Loss reserve, Loss adjustment expense (LAE) reserve
Policyholders' surplus

Insurer's assets minus liabilities, representing the cushion that absorbs unexpected losses and supports solvency; analogous to shareholders' equity for a stock insurer.

Related: Risk-based capital (RBC), Liquidity
Combined ratio

Sum of loss and expense ratios; a measure of underwriting profitability where a ratio below 100% indicates an underwriting gain before investment income.

Related: Loss ratio, Expense ratio, Underwriting income
Loss ratio

Incurred losses and loss adjustment expenses divided by earned premium; shows the share of premium consumed by claims and indicates pricing adequacy.

Related: Combined ratio, Loss reserve
Expense ratio

Underwriting expenses divided by written premium; measures the cost of acquiring and servicing business relative to premium volume and is a component of the combined ratio.

Regulatory capital standard that compares an insurer's capital to risk-based requirements tied to asset, credit, and underwriting risk; identifies weakly capitalized companies.

Related: IRIS ratios, Policyholders' surplus
IRIS ratios

Set of financial ratios used by regulators to screen insurers for potential solvency problems; unusual values trigger further review rather than automatic action.

Computer simulation estimating potential losses from natural or man-made disasters; used for pricing, reinsurance purchasing, capital adequacy planning, and risk transfer decisions.

Related: Enterprise risk management (ERM), Reinsurance
