The FDIC examiner told us we need to include "annual percentage yield" at the bottom of an indoor rate board, I thought that if the rates were advertised inside the bank, as long as we stated APY, that "annual percentage yield" did not have to be included on the board. Thank you in advance for any advice given on this.

APY is sufficient. The indoor sign must also contain a statement advising consumers to contact an employee for further information about applicable fees and terms. Tell your examiner to refer to §1030.8(e)(2):

(2) Indoor signs. (i) Signs inside the premises of a depository institution (or the premises of a deposit broker) are not subject to paragraphs (b), (c), (d) or (e)(1) of this section.

(ii) If a sign exempt by paragraph (e)(2) of this section states a rate of return, it shall:

(A) State the rate as an “annual percentage yield,” using that term or the term “APY.” The sign shall not state any other rate, except that the interest rate may be stated in conjunction with the annual percentage yield to which it relates.

(B) Contain a statement advising consumers to contact an employee for further information about applicable fees and terms.

If your examiner looks at that section (1030.8(e)(2)) in BankersOnline's Regulations pages, he or she will also see an Editor's note we added to the text explaining why "indoor sign" isn't restricted to signs that can only be read by someone inside the building.
