(a) Tax equity finance transactions. A national bank or Federal savings association may engage in a tax equity finance transaction pursuant to 12 U.S.C. 24(Seventh) and 1464 only if the transaction is the functional equivalent of a loan, as provided in paragraph (c) of this section, and the transaction satisfies applicable conditions in paragraph (d) of this section. The authority to engage in tax equity finance transactions under this section is pursuant to 12 U.S.C. 24(Seventh) and 1464 lending authority and is separate from, and does not limit, other investment authorities available to national banks and Federal savings associations.

(b) Definitions. For purposes of this section:

(1) Appropriate OCC supervisory office means the OCC office that is responsible for the supervision of a national bank or Federal savings association, as described in subpart A of 12 CFR part 4;

(2) Capital and surplus has the same meaning that this term has in 12 CFR 32.2.

(3) Tax equity finance transaction means a transaction in which a national bank or Federal savings association provides equity financing to fund a project or projects that generate tax credits or other tax benefits and the use of an equity-based structure allows the transfer of those credits and other tax benefits to the national bank or Federal savings association.

(c) Functional equivalent of a loan. A tax equity finance transaction is the functional equivalent of a loan if:

(1) The structure of the transaction is necessary for making the tax credits or other tax benefits available to the national bank or Federal savings association;

(2) The transaction is of limited tenure and is not indefinite, including retaining a limited investment interest that is required by law to obtain continuing tax benefits or needed to obtain the expected rate of return;

(3) The tax benefits and other payments received by the national bank or Federal savings association from the transaction repay the investment and provide the expected rate of return at the time of underwriting;

(4) Consistent with paragraph (c)(3) of this section, the national bank or Federal savings association does not rely on appreciation of value in the project or property rights underlying the project for repayment;

(5) The national bank or Federal savings association uses underwriting and credit approval criteria and standards that are substantially equivalent to the underwriting and credit approval criteria and standards used for a traditional commercial loan;

(6) The national bank or Federal savings association is a passive investor in the transaction and is unable to direct the affairs of the project company; and

(7) The national bank or Federal savings association appropriately accounts for the transaction initially and on an ongoing basis and has documented contemporaneously its accounting assessment and conclusion.

(d) Conditions on tax equity finance transactions. A national bank or Federal savings association may engage in tax equity finance transactions only if:

(1) The national bank or Federal savings association cannot control the sale of energy, if any, from the project;

(2) The national bank or Federal savings association limits the total dollar amount of tax equity finance transactions undertaken pursuant to this section to no more than five percent of its capital and surplus, unless the OCC determines, by written approval of a written request by the national bank or Federal savings association to exceed the five percent limit, that a higher aggregate limit will not pose an unreasonable risk to the national bank or Federal savings association and that the tax equity finance transactions in the national bank's or Federal savings association's portfolio will not be conducted in an unsafe or unsound manner; provided, however, that in no case may a national bank or Federal savings association's total dollar amount of tax equity finance transactions undertaken pursuant to this section exceed 15 percent of its capital and surplus;

(3) The national bank or Federal savings association has provided written notification to the appropriate OCC supervisory office, prior to engaging in each tax equity finance transaction that includes its evaluation of the risks posed by the transaction;

(4) The national bank or Federal savings association can identify, measure, monitor, and control the associated risks of its tax equity finance transaction activities individually and as a whole on an ongoing basis to ensure that such activities are conducted in a safe and sound manner; and

(5) The national bank or Federal savings association obtains a legal opinion or has other good faith, reasoned bases for making a determination that tax credits or other tax benefits are available before engaging in a tax equity finance transaction.

(e) Applicable legal requirements. The transaction is subject to the substantive legal requirements of a loan, including the lending limits prescribed by 12 U.S.C. 84 and 12 U.S.C. 1464(u), as appropriate, as implemented by 12 CFR part 32, and if the active investor or project sponsor of the transaction is an affiliate of the bank, to the restrictions on transactions with affiliates prescribed by 12 U.S.C. 371c and 371c-1, as implemented by 12 CFR part 223.
