What allows the insured to report values of contents to the insurance company under a form that requires a coinsurance clause?

The Reporting Form is the correct choice because it specifically allows the insured to report the values of their contents to the insurance company on an ongoing basis. This type of policy is particularly useful for businesses or individuals with fluctuating inventory values, as it requires the insured to report their actual values at regular intervals, ensuring that the coverage remains adequate and that the coinsurance requirement is being met.

In a coinsurance clause, the insured is typically required to insure their property for a certain percentage of its actual value; if they fail to do so, they may face a penalty in the event of a loss. The Reporting Form aids in this process by allowing adjustments to the reported values, helping to maintain compliance with the coinsurance condition.

Other options do not fit this function as directly. A Valued Contract establishes a fixed value for an insured item, which does not allow for changes in reported values. A General Policy might refer to broader terms or coverages but lacks the specificity of dealing with fluctuating values directly. An Inventory Form may be relevant for listing items but does not necessarily imply an ongoing reporting relationship with the insurance company in relation to coinsurance.
