What does the "Apportionment Clause" specify in an insurance policy?

The Apportionment Clause in an insurance policy refers to the method by which coverage is distributed among multiple insurance policies applicable to the same property or risk. This clause becomes particularly relevant when there are overlapping policies that provide coverage for similar risks. In such cases, the Apportionment Clause outlines how the payouts will be split among the different insurers, ensuring that the insured does not receive a total amount exceeding the loss but can still benefit from all applicable coverage. This is essential for maintaining fairness and preventing the insured from collecting more than what is rightfully owed based on the actual loss.

In this context, the other options do not accurately represent the function of the Apportionment Clause. Calculating premiums does not relate to how coverage is divided among policies. Claims disputes management typically involves claim processes and procedures rather than the distribution of coverage. Subrogation, which deals with the insurer's right to recover costs from third parties after paying a claim, is a separate concept that does not define how insurance coverage is apportioned among multiple policies.
