Policy endorsement, also known as Mid-Term Adjustment (MTA), is the process of making modifications to an active insurance policy during its term. Common modifications include adding or removing coverage, or updating policy attributes, such as limits and deductibles. Endorsements usually affect the policy price and create a new policy version instead of updating the existing record. This new version includes the applied changes, along with a recalculated standard premium. It also contains a prorated term premium that’s calculated based on the effective date of the endorsement.
Make sure you have these details.
