(2) Small loan to a business product line. The OCC determines whether a bank passes the geographic distribution test for the small loan to a business product line by comparing the bank's small loans to businesses originated in low- or moderate-income census tracts in the assessment area as a percentage of the bank's small loans to businesses originated in the assessment area to either the associated geographic demographic comparator or the associated geographic peer comparator.
(3) Small loan to a farm product line. The OCC determines whether a bank passes the geographic distribution test for the small loan to a farm product line by comparing the bank's small loans to farms originated in low- or moderate-income census tracts in the assessment area as a percentage of the bank's small loans to farms originated in the assessment area to the associated geographic demographic comparator or the associated geographic peer comparator.
(c) Borrower distribution test - (1) Home mortgage lending product line. The OCC determines whether a bank passes the borrower distribution test for a home mortgage lending product line by comparing the bank's home mortgage loans originated to low- and moderate-income families in the assessment area as a percentage of the bank's home mortgage loans originated in the assessment area to either the associated borrower demographic comparator or the associated borrower peer comparator.
(2) Automobile lending product line, other revolving credit plan product line, or other consumer loan product line.

(3) Small loan to a business product line. The OCC determines whether a bank passes the borrower distribution test for the small loan to a business product line by comparing the bank's small loans to businesses originated to CRA-eligible businesses in the assessment area as a percentage of the bank's small loans to businesses originated in the assessment area to either the associated demographic borrower comparator or the associated peer comparator.
(4) Small loan to a farm product line. The OCC determines whether a bank passes the borrower distribution test for the small loan to a farm product line by comparing the bank's small loans to farms originated to CRA-eligible farms in the assessment area as a percentage of the bank's small loans to farms originated in the assessment area to either the associated demographic borrower comparator or the associated peer comparator.
