(a) In general. A savings association must pay interest from the date the savings association receives a payment for conversion shares until the date the savings association completes or terminates the conversion. The savings association must pay interest at no less than its passbook rate for amounts paid in cash, check, or money order.

(b) Interest on withdrawals from savings accounts. If a subscriber withdraws money from a savings account to purchase conversion shares, the savings association must pay interest on the payment until the savings association completes or terminates the conversion as if the withdrawn amount remained in the account.

(c) Interest on withdrawals from certificates of deposit. If a depositor fails to maintain the applicable minimum balance requirement because he or she withdraws money from a certificate of deposit to purchase conversion shares, the savings association may cancel the certificate and pay interest at no less than its passbook rate on any remaining balance.
