Why review annually
The household moved. The form may not have.
A policy you bought in a different year was built for a different household. Income moved. People were born, left, or died. A beneficiary form can sit unchanged while the family does not.
An annual review is a look at what you own now — face amount, type, term remaining, workplace vs individual, and the job the policy was bought to do. It is not a sales script for a new product.
