APH Yield (Actual Production History)
APH yield is the average of a farmer's historical crop yields over 4–10 years, used as the basis for federal crop insurance coverage.
Actual Production History (APH) yield is the simple average of a producer's verified crop yields over a base period of four to ten consecutive years. It serves as the benchmark for federal crop insurance programs administered by the USDA Risk Management Agency (RMA). Insurance guarantees are calculated as a percentage of the APH yield multiplied by the projected price. If actual production falls below the guarantee, an indemnity is paid. Farmers can build their APH by maintaining accurate yield records and reporting them to their crop insurance agent. Years with exceptionally low yields may be replaced by a yield floor or plug yield to prevent a catastrophic event from permanently depressing the APH.
