A savings and loan holding company or any savings association or any affiliate of either may vary the consideration for any product or package of products based on a customer's maintaining a combined minimum balance in certain products specified by the company varying the consideration (eligible products), if:

(1) That company (if it is a savings association) or a savings association affiliate of that company (if it is not a savings association) offers deposits, and all such deposits are eligible products; and

(2) Balances in deposits count at least as much as non-deposit products toward the minimum balance.

(b) Limitations on exception. This exception shall terminate upon a finding by the Board that the arrangement is resulting in anti-competitive practices.
