A supplemental crop insurance program will enhance crop insurance protection, thereby increasing within-year protection. A revenue and target price program, respectively, protect against revenue and price declines that occur across years. Because all three of the programs must fit within budget parameters, the greater the focus on a supplemental insurance program the lower will be across-year protection, and vice versa.

The discussion in the preceding paragraph presumes that the supplemental insurance coverage provided by STAX and SCO programs is the same proposed in last year's farm bill drafts. Both of these programs based their revenue guarantees on crop insurance's pre-plant projected prices. These projected prices are based on harvest futures prices for the crop year. This design choice results only in within-year protection. An alternative design option is to base prices on historical prices, which would introduce the potential for across-year protection.
