Assessable insurance is a structure where final premium recovery may be adjusted after the policy year if claims are higher than expected.
Insurance mechanics
Under this model, an insurer collects an initial premium and may later assess members or policyholders for shortfalls. The opposite structure is a nonassessable policy, where charges are fixed and not revisited for portfolio-level loss experience.
Claims and financial logic
The mechanism absorbs volatility in small mutual or cooperative pools, but it increases policyholder uncertainty because of potential additional contributions.
Regulation and governance
Jurisdictions typically require clear disclosure, member agreements, and transparent assessment calculations so policyholders can predict maximum possible obligations.
Example
In a mutual commercial auto block with unexpectedly severe losses, the insurer may call an additional assessment invoice before year-end to restore reserve adequacy.
