Form-specific context

Distinguish this form from nearby requirements.

CG 20 37 is commonly requested for the period after the named insured's operations have been completed. It is often discussed alongside an ongoing-operations endorsement, but the two references address different stages of the work. The completed project, contractual requirement, schedule, and policy dates should be reconciled before anyone describes the endorsement as satisfying a contract.

Common points to separate

  • Completed operations is distinct from work that is still underway
  • The endorsement does not automatically extend every contractual promise
  • A scheduled person or organization must be identified accurately on the issued form
Information organized

Facts to prepare.

  • Scheduled additional insured name
  • Completed project or operation
  • Location information when required
  • Written contract requirements
  • Completed operations coverage period
Quality control

Review before using the form.

  • Confirm the endorsement was actually issued and scheduled correctly
  • Distinguish completed operations from ongoing operations requirements
  • Read the edition, policy, and other endorsements together
Edition, rights, and market boundary

A form guide is educational and does not interpret coverage, establish that a form applies to a specific policy, prove market access, create a risk submission, or authorize release of material to a market. Confirm the current edition, jurisdiction, policy, carrier, and form requirements with the authorized publisher and intended insurer. Use the insurer-issued endorsement or authorized Verisk access. Hedge does not publish the ISO file.
