Under California law, when an insurance company unreasonably refuses to settle a claim within its policy limits, and the case then produces a larger judgment at trial, the insurance company can become responsible for the entire judgment, not just the original policy amount. This rule exists because an insurer's core obligation to its own policyholder includes trying to settle a claim within limits when liability is clear and damages are likely to exceed the policy, precisely so the policyholder is not left personally exposed to a judgment the insurer could have avoided. California's Unfair Claims Settlement Practices statute identifies failing to attempt in good faith to effectuate a prompt, fair, and equitable settlement as one of the specific practices that can support a bad-faith claim against an insurer.
