The Enhanced Coverage Option (ECO) is a new crop insurance option that provides additional area-based coverage for a portion of your underlying crop insurance policy deductible. It must be purchased as an endorsement to the Yield Protection, Revenue Protection, Revenue Protection with the Harvest Price Exclusion, Actual Production History or Yield Based Dollar Amount of Insurance policy. ECO offers producers a choice of 90 or 95 percent trigger levels. Trigger means the percentage of expected yield or revenue at which a loss becomes payable.
