Which document is the primary source of information for underwriting in insurance?

The application is the primary source of information for underwriting in insurance because it contains essential details about the applicant and the risk to be covered. This document provides underwriters with vital information such as the applicant's personal data, financial history, health status, and any relevant risk factors.

By evaluating the information contained in the application, underwriters can make informed decisions regarding the acceptance, modification, or rejection of the insurance coverage. This includes assessing whether the risk aligns with the insurer's guidelines and determines the appropriate premium.

The other documents, while important to the overall insurance process, serve different purposes. The policy document outlines the terms and conditions of the insurance coverage after underwriting has been completed. The claims report is generated after an insurance event has occurred and primarily focuses on the claim itself, not on the risk assessment. A binder acts as a temporary proof of insurance coverage but does not provide the detailed risk information needed for underwriting decisions.
