 We are also allowing non-contiguous parcels of land that qualify for optional units to also qualify for enterprise units. An enterprise unit consists of all insurable acreage of the same insured crop within one county. This structure allows a producer to insure all acres of this crop in the county together, as opposed to other structures that separate the acreage for insurance. Often, the use of enterprise units leads to lower premium rates because of the lower risk associated with the geographic diversification.
