Retained limits and SIRs

One way for businesses to cut down their liability insurance premiums is to negotiate a policy with a retained limit or self-insured retention (SIR), which is somewhat like a deductible. With such policies, the insured is essentially agreeing to self-insure and self-defend for smaller claims, and to tender and demand a defense only for liability claims that exceed a certain value. However, writing such insurance is itself risky for insurers. The California Courts of Appeal have held that primary insurers on policies with a SIR must still provide an "immediate, 'first dollar' defense" (subject, of course, to their right to later recover the SIR amount from the insured) unless the policy expressly imposes exhaustion of the SIR as a precondition to the duty to defend.
