Which of the following are printed addendums to a contract that are used to change the policy's original terms, conditions, or coverages?

Endorsements are printed addendums to a contract specifically designed to modify the original terms, conditions, or coverages of a policy. They serve as an official documentation process that provides additional details, clarifications, or changes to the existing agreement between the insurer and the insured. This can include changes in coverage limits, additions of new coverages, or alterations of existing provisions, ensuring that all modifications are formally recognized and legally binding.

In contrast, prospectuses typically offer summaries and overviews of a policy or investment rather than modifying its terms. Declarations provide essential information about the policy such as the coverage period, insured parties, and policy limits, but they do not alter the foundational terms of the contract. Conditions outline the responsibilities of both the insurer and the insured and while they are critical to the policy, they do not explicitly change the terms or coverages. Thus, endorsements are unique in that they explicitly modify the original contract's terms, making them the correct choice for this question.
