``SEC. 54. CREDIT TO HOLDERS OF CLEAN ENERGY BONDS.

    ``(a) Allowance of Credit.--In the case of a taxpayer who holds a 
clean energy bond on a credit allowance date of such bond, which occurs 
during the taxable year, there shall be allowed as a credit against the 
tax imposed by this chapter for such taxable year an amount equal to 
the sum of the credits determined under subsection (b) with respect to 
credit allowance dates during such year on which the taxpayer holds 
such bond.
    ``(b) Amount of Credit.--
            ``(1) In general.--The amount of the credit determined 
        under this subsection with respect to any credit allowance date 
        for a clean energy bond is 25 percent of the annual credit 
        determined with respect to such bond.
            ``(2) Annual credit.--The annual credit determined with 
        respect to any clean energy bond is the product of--
                    ``(A) the credit rate determined by the Secretary 
                under paragraph (3) for the day on which such bond was 
                sold, multiplied by
                    ``(B) the outstanding face amount of the bond.
            ``(3) Determination.--For purposes of paragraph (2), with 
        respect to any clean energy bond, the Secretary shall determine 
        daily or caused to be determined daily a credit rate which 
        shall apply to the first day on which there is a binding, 
        written contract for the sale or exchange of the bond. The 
        credit rate for any day is the credit rate which the Secretary 
        or the Secretary's designee estimates will permit the issuance 
        of clean energy bonds with a specified maturity or redemption 
        date without discount and without interest cost to the 
        qualified issuer.
            ``(4) Credit allowance date.--For purposes of this section, 
        the term `credit allowance date' means--
                    ``(A) March 15,
                    ``(B) June 15,
                    ``(C) September 15, and
                    ``(D) December 15.
        Such term also includes the last day on which the bond is 
        outstanding.
            ``(5) Special rule for issuance and redemption.--In the 
        case of a bond which is issued during the 3-month period ending 
        on a credit allowance date, the amount of the credit determined 
        under this subsection with respect to such credit allowance 
        date shall be a ratable portion of the credit otherwise 
        determined based on the portion of the 3-month period during 
        which the bond is outstanding. A similar rule shall apply when 
        the bond is redeemed or matures.
    ``(c) Limitation Based on Amount of Tax.--
            ``(1) In general.--The credit allowed under subsection (a) 
        for any taxable year shall not exceed the excess of--
                    ``(A) the sum of the regular tax liability (as 
                defined in section 26(b)) plus the tax imposed by 
                section 55, over
                    ``(B) the sum of the credits allowable under this 
                part (other than subpart C thereof, relating to 
                refundable credits).
            ``(2) Carryover of unused credit.--If the credit allowable 
        under subsection (a) exceeds the limitation imposed by 
        paragraph (1) for such taxable year, such excess shall be 
        carried to the succeeding taxable year and added to the credit

                date) owned by a qualified borrower.
                    ``(B) Refinancing rules.--For purposes of paragraph 
                (1)(B), a qualified project may be refinanced with 
                proceeds of a clean energy bond only if the 
                indebtedness being refinanced (including any obligation 
                directly or indirectly refinanced by such indebtedness) 
                was originally incurred by a qualified borrower after

                the enactment of this section with respect to a 
                qualified project, but only if prior to the payment of 
                such expenditure, the qualified borrower declared its 
                intent to reimburse such expenditure with the proceeds 
                of a clean energy bond.

                that a qualified borrower takes any action within its 
                control which causes such proceeds not to be used for a 
                qualified project. The Secretary shall prescribe 
                regulations specifying remedial actions that may be 
                taken (including conditions to taking such remedial 
                actions) to prevent an action described in the 
                preceding sentence from causing a bond to fail to be a

                expected economic life of the facilities being financed 
                with the proceeds from the sale of such issue.
            ``(2) Determination of averages.--For purposes of paragraph

        shall not be treated as a clean energy bond unless it is part 
        of an issue which provides for an equal amount of principal to 
        be paid by the qualified issuer during each calendar year that 
        the issue is outstanding.
    ``(f) Credit Included in Gross Income.--Gross income includes the 
amount of the credit allowed to the taxpayer under this section 
(determined without regard to subsection (c)) and the amount so

            ``(1) In general.--An issue shall be treated as meeting the 
        requirements of this subsection if--

                sale of the issue are to be spent for 1 or more 
                qualified projects within the 5-year period beginning 
                on the date of issuance of the clean energy bond,

                beginning on the date of issuance of the clean energy 
                bond or, in the case of a clean energy bond, the 
                proceeds of which are to be loaned to 2 or more 
                qualified borrowers, such binding commitment will be 
                incurred within the 6-month period beginning on the

                borrower, and

        (1)(A), the Secretary may extend such period if the qualified 
        issuer establishes that the failure to satisfy the 5-year 
        requirement is due to reasonable cause and the related projects 
        will continue to proceed with due diligence.
            ``(3) Failure to spend required amount of bond proceeds 
        within 5 years.--To the extent that less than 95 percent of the 
        proceeds of such issue are expended within such 5-year period 
        (and no extension has been obtained under paragraph (2)), the 
        qualified issuer shall redeem all of the nonqualified bonds on 
        the earliest call date subsequent to the expiration of the 5-
        year period. If such earliest call date is more than 90 days 
        subsequent to the expiration of the 5-year period, the 
        qualified issuer shall establish a yield-restricted defeasance 
        escrow within such 90 days to retire such nonqualified bonds on 
        the earlier of the date which is 10 years after the issue date 
        or the first call date. For purposes of this paragraph, the 
        term `nonqualified bonds' means the portion of the outstanding 
        bonds in an amount that, if the remaining bonds were issued on 
        the fifth anniversary of the date of the issuance of the issue,

            ``(1) In general.--A bond which is part of an issue shall 
        not be treated as a clean energy bond unless, with respect to

        satisfies the arbitrage rebate requirements of section 148 with 
        respect to gross proceeds of the issue (other than any amounts 
        applied in accordance with subsection (g)). For purposes of 
        such requirements, yield over the term of an issue shall be 
        determined under the principles of section 148 based on the 
        qualified issuer's payments of principal, interest (if any), 
        and fees for qualified guarantees on such issue.
