7 U.S. Code § 9017 - Agriculture risk coverage
The agriculture risk coverage guarantee for a crop year for a covered commodity shall equal 86 percent of the benchmark revenue.
If the yield per planted acre for the covered commodity or historical county yield per planted acre for the covered commodity for any of the 5 most recent crop years, as determined by the Secretary, is less than 70 percent of the transitional yield, as determined by the Secretary, the amounts used for any of those years in paragraph (2)(A) or (3)(A)(i) shall be 70 percent of the transitional yield.
If the national average market price received by producers during the 12-month marketing year for any of the 5 most recent crop years is lower than the reference price for the covered commodity, the Secretary shall use the reference price for any of those years for the amounts in paragraph (2)(B) or (3)(A)(ii).
If the Secretary determines that agriculture risk coverage payments are required to be provided for the covered commodity, payments shall be made beginning October 1, or as soon as practicable thereafter, after the end of the applicable marketing year for the covered commodity.
