For purposes of determining statutory limits that are based on the amount of a national bank's capital and/or surplus, the provisions of this section are to be used, rather than the definitions of capital contained in subparts A through J of this part.

(b) Capital Stock. The term capital stock as used in provisions of law relating to the capital stock of national banks, other than 12 U.S.C. 101, 177, and 178 shall have the same meaning as the term capital set forth in paragraph (a) of this section.

(1) Capital surplus; undivided profits; reserves for contingencies and other capital reserves (excluding accrued dividends on perpetual and limited life preferred stock); net worth certificates issued pursuant to 12 U.S.C. 1823(i); minority interests in consolidated subsidiaries; and allowances for loan and lease losses; minus intangible assets;

(2) Mortgage servicing assets;

(3) Mandatory convertible debt to the extent of 20 percent of the sum of paragraphs (a) and (c) (1) and (2) of this section;

(e) Definitions.

(1) Allowance for loan and lease losses means the balance of the valuation reserve on December 31, 1968, plus additions to the reserve charged to operations since that date, less losses charged against the allowance net of recoveries.

(2) Capital surplus means the total of those accounts reflecting:

(i) Amounts paid in in excess of the par or stated value of capital stock;

(ii) Amounts contributed to the national bank other than for capital stock;

(iii) Amounts transferred from undivided profits pursuant to 12 U.S.C. 60; and

(f) Requirements and restrictions: Limited life preferred stock, mandatory convertible debt, and other subordinated debt—

(1) Requirements. Issues of limited life preferred stock and subordinated notes and debentures (except mandatory convertible debt) shall have original weighted average maturities of at least five years to be included in the definition of surplus. In addition, a subordinated note or debenture must also:

(i) Be subordinated to the claims of depositors;

(ii) State on the instrument that it is not a deposit and is not insured by the FDIC;

(iii) Be unsecured;

(iv) Be ineligible as collateral for a loan by the issuing national bank;

(vi) Provide that no prepayment (including payment pursuant to an acceleration clause or redemption prior to maturity) shall be made without prior OCC approval unless the national bank remains an eligible bank, as defined in 12 CFR 5.3(g), after the prepayment.

(2) Restrictions. The total amount of mandatory convertible debt not included in paragraph (c)(3) of this section, limited life preferred stock, and subordinated notes and debentures considered as surplus is limited to 50 percent of the sum of paragraphs (a) and (c) (1), (2) and (3) of this section.

(3) Reservation of authority. The OCC expressly reserves the authority to waive the requirements and restrictions set forth in paragraphs (f)(1) and (2) of this section, in order to allow the inclusion of other limited life preferred stock, mandatory convertible notes and subordinated notes and debentures in the capital base of any national bank for capital adequacy purposes or for purposes of determining statutory limits. The OCC further expressly reserves the authority to impose more stringent conditions than those set forth in paragraphs (f)(1) and (2) of this section to exclude any component of tier 1 or tier 2 capital, in whole or in part, as part of a national bank's capital and surplus for any purpose.
