(a) In general. A depositary bank shall begin to accrue interest or dividends on funds deposited in an interest-bearing account not later than the business day on which the depositary bank receives credit for the funds. For the purposes of this section, the depositary bank may
(1) Rely on the availability schedule of its Federal Reserve Bank, Federal Home Loan Bank, or correspondent bank to determine the time credit is actually received; and
(2) Accrue interest or dividends on funds deposited in interest-bearing accounts by checks that the depositary bank sends to paying banks or subsequent collecting banks for payment or collection based on the availability of funds the depositary bank receives from the paying or collecting banks.
(b) Special rule for credit unions. Paragraph (a) of this section does not apply to any account at a bank described in §229.2(e)(4), if the bank
(1) Begins the accrual of interest or dividends at a later date than the date described in paragraph (a) of this section with respect to all funds, including cash, deposited in the account; and
(2) Provides notice of its interest or dividend payment policy in the manner required under §229.16(d).
(c) Exception for checks returned unpaid. This subpart does not require a bank to pay interest or dividends on funds deposited by a check that is returned unpaid.
