Fine arts insurance coverage on both personal and commercial exposures and collections is usually written under inland marine coverage forms. In most cases, each item is scheduled and insured for specific stated amount. Because statuary, sculptures, paintings, and antiques are "one-of-a-kind" art objects, competent appraisers must determine their values. These values should be adjusted regularly because of the inconstancy in the art market that can cause values to skyrocket and then plunge. Security and loss prevention measures that are subject to enforceable warranties are often required. This explanation of insurance benefits is provided by Insurance Marketplace.
