A commercial general liability policy has an aggregate limit of $1,000,000.

An aggregate limit is the maximum amount the insurer will pay for all covered claims subject to that aggregate during the policy period. The policy aggregate is $1,000,000. The insurer has already paid $100,000 + $500,000 + $300,000, for a total of $900,000. That leaves only $100,000 available under the aggregate. Therefore, even though the new claim is $300,000, the insurer can pay only the remaining $100,000. Option C would be correct only if the full aggregate remained available or if the claim were subject to a separate unaffected limit. Option A is wrong because some aggregate remains. Option D is the original aggregate, not the remaining available amount. Brokers must explain aggregate limits to commercial clients because a policy may appear to have a large limit, but prior claims can erode available coverage. This is especially important for businesses with frequent premises, products, or operations liability losses.
