Policyholder Surplus

DEFINITION of 'Policyholder Surplus'

The assets of a policyholder-owned insurance company (also called a mutual insurance company) minus its liabilities. Policyholder surplus is one indicator of an insurance company’s financial health. It gives an insurance company another source of funds, in addition to its reserves and reinsurance, if it needs to pay a higher than expected amount of claims. When an insurance company is publicly owned, its assets minus its liabilities are instead called shareholders’ equity.

BREAKING DOWN 'Policyholder Surplus'

Policyholder surplus is one metric that insurance rating companies use when developing the simple letter ratings ranging from A++ to F. Consumers can turn to these ratings for help in choosing an insurance company that is strong financially. It’s important for consumers to choose an insurer that can afford to pay its policyholders’ claims under varying circumstances, even if a widespread disaster like a severe storm means that thousands of policyholders are simultaneously filing claims.

Policyholder surplus is also a component of various calculations that ratings companies can use to evaluate the financial strength of insurance companies. These calculations include ratios such as reserve development to policyholder surplus, loss to policyholder surplus, net liabilities to policyholder surplus and net premiums written to policyholder surplus, among others. Calculations involving policyholder surplus are also used by state insurance regulators to evaluate which insurers might require their attention due to financial weakness or over-reliance on reinsurance. For publicly traded insurance companies, the same calculations can be performed by substituting shareholders’ equity for policyholder surplus.

Interpreting the results of these calculations requires specialized knowledge, not just common sense. For example, insurance company examiners will consider the company’s change in policyholder surplus from year to year as one component of assessing whether the insurer is becoming financially stronger, weaker or staying about the same. While it might seem like a large increase in policyholder surplus from one year to the next would always be a good sign, it could sometimes indicate that the insurer is on the verge of insolvency.
