(3) Contract for qualified withdrawal.—Under paragraph (1), an amount shall not be treated as remaining in a capital construction fund at the close of a taxable year to the extent there is a binding contract at the close of the taxable year for a qualified withdrawal of the amount for an identified item for which the withdrawal may be made.

(4) Excess earnings.—If the Secretary determines that the balance in a capital construction fund exceeds the amount appropriate to meet the vessel construction program objectives of the person that established the fund, the amount of the excess shall be treated as a nonqualified withdrawal under paragraph (1) unless the person develops appropriate program objectives within 3 years to dissipate the excess.

(f) Tax Determinations.—

(1) In general.—For a taxable year for which there is a nonqualified withdrawal (including an amount treated as a nonqualified withdrawal under subsection (e)), the tax imposed by chapter 1 of the Internal Revenue Code of 1986 (26 U.S.C. ch. 1) shall be determined by—

(A) excluding the withdrawal from gross income; and

(3) Tax benefit rule.—If any portion of a nonqualified withdrawal is properly attributable to deposits (except earnings on deposits) made by the taxpayer in a taxable year that did not reduce the taxpayer's liability for tax under chapter 1 of such Code (26 U.S.C. ch. 1) for a taxable year before the taxable year in which the withdrawal occurs—

(A) that portion shall not be taken into account under paragraph (1); and

(B) an amount equal to that portion shall be allowed as a deduction under section 172 of such Code (26 U.S.C. 172) for the taxable year in which the withdrawal occurs.

(4) Coordination with deduction for net operating losses.—A nonqualified withdrawal excluded from gross income under paragraph (1) shall be excluded in determining taxable income under section 172(b)(2) of such Code (26 U.S.C. 172(b)(2)).
