The general regulations governing United States securities, part 306 of this chapter, apply, as the regulations for similar transactions and operations in certificated debentures. To the extent that the provisions in this part differ from the provisions in part 306, the provisions in this part shall prevail.

Debentures presented for redemption at call or maturity, or for authorized prior purchase, or for conversion to book-entry form, must be delivered at the expense and risk of the holder. Debentures bearing restricted assignments may be forwarded by registered mail, but for the owner's protection debentures bearing unrestricted assignments should be forwarded by insured registered mail.

Debentures, which by their terms are subject to call, may be called for redemption, in whole or in part, at par and accrued interest, on any interest date on three months' notice. No transfers or denominational exchanges in certificated debentures covered by a given call will be made on the books of the Department of the Treasury on or after the announcement of such call. However, this does not affect the right of a holder of such debenture to sell and assign it on or after the announcement of the call date.

(a) For redemption. To facilitate the redemption of called or maturing debentures, they may be presented and surrendered in the manner prescribed in this section in advance of the call or maturity date, as the case may be. Early presentation by holders will insure prompt payment of principal and interest when due. The debentures must first be assigned by the registered payee or his assignee, or by his duly constituted representative, if required, in the form and manner indicated in § 337.5, and must then be submitted to the Bureau of the Fiscal Service at the address given in § 337.14, accompanied by appropriate written advice. A transmittal advice for this purpose will accompany the notice of call.

(b) For purchase. Debentures, the purchase of which has been authorized prior to call or maturity, may be assigned as instructed in paragraph (a) of this section and immediately submitted in accordance with procedures prescribed by HUD for this purpose.

(a) If the registered payee, or an assignee holding a certificated debenture under proper assignment from the registered payee, desires that payment be made to such payee or assignee, the debenture need not be assigned. If the owner desires for any reason that payment be made to another, without intermediate assignment, the debentures should be assigned to “The Federal Housing Commissioner for redemption (or, purchase) for the account of ____,” inserting the name and address of the person to whom payment is to be made. Proof of the authority of the individual assigning on behalf of an owner will be required in accordance with part 306 of this chapter.

(b) An assignment in blank or other assignment having similar effect will be recognized, but in that event the debenture would be, in effect, payable to bearer, and payment will be made in accordance with the instructions received from the person surrendering the debenture for redemption or purchase. For the owner's protection, such assignments should be avoided unless the owner is willing to lose the protection afforded by registration.

(c) Debentures submitted for conversion to book-entry form should be assigned to “The Federal Housing Commissioner for conversion to book-entry debentures for the account of ____.” The registration on the book-entry account and/or the account number in which the debentures should be deposited should be indicated.

(d) All assignments must be made on the debentures themselves unless otherwise authorized by the Department of Treasury.

Upon implementation of the book-entry debenture system, to be announced in advance by separate public notice, all new debentures will be issued only in book-entry form, and may not thereafter be converted to certificated form.

Certificated debentures may, upon the owner's request in accordance with § 337.5(c), be converted to book-entry. If such action is taken, the owner shall be deemed to have irrevocably waived the right to hold such debenture in certificated form.

Upon implementation of the book-entry debenture system, to be announced in advance by separate public notice, any transfer or denominational exchange of certificated debentures generally will be made in book-entry form. If certificated debentures are desired, the owner should so request in writing, before the book-entry debentures are issued.

When certificated debentures are tendered for purchase prior to maturity in order that the proceeds thereof be applied to pay for mortgage insurance premiums, any difference between the amount of the debentures purchased and the amount of the mortgage insurance premium will generally be issued to the owner in the form of a book-entry debenture in the exact amount of such difference, provided it is one dollar ($1.00) or more. However, if the owner so requests, such difference will be settled with certificated debenture(s), together with a cash adjustment, if any. Such request should be made in writing, before the book-entry debenture in the amount of the difference is issued.

Final interest on any debenture, whether purchased prior to or redeemed on or after the call or the maturity date, will be paid with the principal. In all cases the payment of principal and final interest will be mailed or directed to the payment address given in the form of advice accompanying the debenture surrendered.

Payments on certificated debentures will be made by fiscal agency check in accordance with part 355 of this chapter, or, upon request, by direct deposit (electronic funds transfer) in accordance with part 370 of this chapter. Information as to the deposit account at the financial institution designated to receive a direct deposit payment shall be provided on the appropriate form(s) designated by the Department.
