Who this is built for

Small businesses that insure buildings, tenant improvements, business personal property, or stock.

How to use it

  1. Use a separate row for each property category or location instead of blending different valuation bases.
  2. Enter the valuation date and source so the estimate can be refreshed at renewal.
  3. Use the worksheet as a review prompt only; confirm the actual coinsurance formula, agreed-value provisions, and valuation terms with the policy and insurer.

What this template cannot prove

A worksheet or email template cannot create insurance coverage, establish legal worker status, modify an insurance policy, or guarantee that a contract requirement has been satisfied. When a field depends on coverage, confirm the policy or endorsement. When it depends on state law, use the responsible state authority.
