Insurance companies utilize all of the following documents for contract changes except one. Identify the exception.

In the context of insurance policies, a telephone change log typically records verbal communications and requests for changes but is not an official document used to modify or amend a contract. While it may be useful for internal record-keeping or to verify that a discussion took place, it does not serve as a formal mechanism for implementing changes to an insurance contract.

In contrast, a rider is an amendment that modifies the coverage of an existing policy, while an endorsement serves a similar purpose by adding, deleting, or altering coverage features. A floater is a type of policy that provides coverage for specific property items that are not limited to a specific location, but it is also a recognized document within the insurance framework. Hence, the only option that does not directly facilitate formal changes to a policy contract is the telephone change log.
