Which clause promises to pay in the event of a covered loss?

The grace period in an insurance policy refers to the additional time granted after a premium payment due date during which the policy remains in force. It does not directly relate to the promise to pay in the event of a covered loss but rather concerns the timing of premium payments to avoid policy lapse.

The incontestable clause in an insurance policy limits the insurer's ability to contest the validity of the policy after a certain period, usually after it has been in force for a specific duration. This clause is not directly associated with the promise to pay for a covered loss but rather addresses the contestability of the policy itself.

An assignment clause in an insurance policy allows the policyholder to transfer their rights or benefits under the policy to another party. This clause does not pertain to the promise to pay in the event of a covered loss but rather deals with the transfer of policy ownership or benefits.
