(g) An obsolete vessel acquired by the Secretary of Transportation under this section which is or becomes twenty-five years old or more, and vessels presently in the Secretary's laid-up fleet which are or become twenty-five years old or more, shall in no case be used for commercial operation, except that any such obsolete vessel, or any such vessel in the laid-up fleet may be used during any period in which vessels may be requisitioned under section 902 of this Act, as amended, and except as otherwise provided in this Act for the employment of the Secretary's vessels in steamship lines on trade routes exclusively serving the foreign trade of the United States.

[Subsection (h) repealed by section 307(6) of Public Law 101-225.]

(i) The Secretary of Transportation is authorized to acquire suitable documented vessels, as defined in section 2101 of title 46, United States Code, with funds in the Vessel Operations Revolving Fund derived from the sale of obsolete vessels in the National Defense Reserve Fleet. For purposes of this subsection, the acquired and obsolete vessels shall be valued at their scrap value in domestic or foreign markets as of the date of the acquisition for or sale from the National Defense Reserve Fleet; except that, in a transaction subject to this section, the value assigned to those vessels will be determined on the same basis, with consideration given to the fair value of the cost of positioning the traded-out vessel to the place of scrapping. All costs incident to the lay-up of the vessel acquired under this subsection may be paid from balances in the Fund. Notwithstanding the provisions of sections 9 and 37 of the Shipping Act, 1916, vessels sold from the National Defense Reserve Fleet under this subsection may be scrapped in approved foreign markets.

(j) Any vessel heretofore or hereafter acquired under this section, or otherwise acquired by the Maritime Administration of the Department of Transportation under any other authority shall be placed in the national defense reserve fleet established under authority of section 11 of the Merchant Ship Sales Act of 1946 (50 U.S.C. App. 1744), and shall not be traded out or sold from such reserve fleet, except as provided for in subsections (g) and (i) of this section. This limitation shall not affect the rights of the Secretary of Transportation to dispose of a vessel as provided in other sections of this title or in titles VII or XI of this Act.

SEC. 511. [46 App. U.S.C. 1161] (a) When used in this section the term "new vessel" means any vessel (1) documented or agreed with the Secretary of Transportation to be documented under the laws of the United States; (2) constructed in the United States after December 31, 1939, or the construction of which has been financed under title V or VII of this Act, as amended, or the construction of which has been aided by a mortgage insured under title XI of this Act as amended; and (3) either (A) of such type, size, and speed as the Secretary of Transportation shall determine to be suitable for use on the high seas or Great Lakes in carrying out the purposes of this Act, but not of less than two thousand gross tons or of less speed than twelve knots, unless the Secretary of Transportation shall determine and certify in each case that a ves

sel of a specified lesser tonnage or speed is desirable for use by the United States in case of war or national emergency, or (B) constructed to replace a vessel or vessels requisitioned or purchased by the United States.

(b) For the purposes of promoting the construction, reconstruction, reconditioning, or acquisition of vessels, or for other purposes authorized in this section, necessary to carry out the policy set forth in title I of this Act, any citizen of the United States who is operating a vessel or vessels in the foreign or domestic commerce of the United States or in the fisheries or owns in whole or in part a vessel or vessels being so operated, or who, at the time of purchase or requisition of the vessel by the Government, was operating a vessel or vessels so engaged or owned in whole or in part a vessel or vessels being so operated or had acquired or was having constructed a vessel or vessels for the purpose of operation in such commerce or in the fisheries, may establish a construction reserve fund, for the construction, reconstruction, reconditioning, or acquisition of new vessels, or for other purposes authorized in this section, to be composed of deposits of proceeds from sales of vessels, indemnities on account of losses of vessels, earnings from the operation of vessels documented under the laws of the United States and from services incident thereto, and receipts, in the form of interest or otherwise, with respect to amounts previously deposited. Such construction reserve fund shall be established, maintained, expended, and used in accordance with the provisions of this section and rules or regulations to be prescribed jointly by the Secretary of Transportation and the Secretary of the Treasury.

(c) In the case of the sale or actual or constructive total loss of a vessel, if the taxpayer deposits an amount equal to the net proceeds of the sale or to the net indemnity with respect to the loss in a construction reserve fund established under subsection (b), then

(1) if the taxpayer so elects in his income-tax return for the taxable year in which the gain was realized, or

(2) in case a vessel if purchased or requisitioned by the United States, or is lost, in any taxable year beginning after December 31, 1939, and the taxpayer receives payment for the vessel so purchased or requisitioned, or receives from the United States indemnity on account of such loss, subsequent to the end of such taxable year, if the taxpayer so elects prior to the expiration of sixty days after the receipt of the payment or indemnity, and in accordance with a form of election to be prescribed by the Commissioner of Internal Revenue with the approval of the Secretary of the Treasury,

no gain shall be recognized to the taxpayer in respect of such sale or indemnification in the computation of net income for the purposes of Federal income or excess-profits taxes. If an election is made under subdivision (2) and if computation or recomputation in accordance with this subsection is otherwise allowable but is prevented, on the date of making such election or within six months thereafter, by any statute of limitation, such computation or recomputation nevertheless shall be made notwithstanding such statute if a claim therefor is filed within six months after the date of making such election.

For the purposes of this subsection no amount shall be considered as deposited in a construction reserve fund unless it is deposited within sixty days after it is received by the taxpayer.

As used in this subsection the term "net proceeds" and the term “net indemnity” mean the sum of (1) the adjusted basis of the vessel and (2) the amount of gain which would be recognized to the taxpayer without regard to this subsection.

(d) The basis for determining gain or loss and for depreciation, for the purposes of Federal income or excess profits taxes, of any new vessel constructed, reconstructed, reconditioned, or acquired by the taxpayer, or with respect to which purchase-money indebtedness is liquidated as provided in subsection (g), in whole or in part out of the construction reserve fund shall be reduced by that portion of the deposits in the fund expended in the construction, reconstruction, reconditioning, acquisition, or liquidation of purchasemoney indebtedness of the new vessel which represents gain not recognized for tax purposes under subsection (c).

(e) For the purposes of this section, (1) if the net proceeds of a sale or the net indemnity in respect of a loss are deposited in more than one deposit, the amount consisting of the gain shall be considered as first deposited; (2) amounts expended, obligated, or otherwise withdrawn shall be applied against the amounts deposited in the fund in the order of deposit; and (3) if any deposit consists in part of gain not recognized under subsection (c), any expenditure, obligation, or withdrawal applied against such deposit shall be considered to consist of gain in the proportion that the part of the deposit consisting of gain bears to the total amount of the deposit.

(f) With respect to any taxable year, amounts on deposit on the last day of such year in a construction reserve fund in accordance with this section and with respect to which all the requirements of subsection (g) have been satisfied, to the extent that such requirements are applicable as of the last day of said taxable year, shall not constitute an accumulation of earnings or profits within the meaning of section 102 of the Internal Revenue Code.

(g) The provisions of subsections (c) and (f) shall apply to any deposit in the construction reserve fund only to the extent that such deposit is expended or obligated for expenditure, in accordance with rules and regulations to be prescribed jointly by the Secretary of Transportation and the Secretary of the Treasury—

(1) under a contract for the construction or acquisition of a new vessel or vessels (or in the discretion of the Secretary of Transportation, for a part interest therein), or, with the approval of the Secretary of Transportation, for the reconstruction or reconditioning of a new vessel or vessels, entered into within (i) two years from the date of deposit or the date of any extension thereof which may be granted by the Secretary of Transportation pursuant to the provisions of section 511(h), in the case of deposits made prior to the date on which these amendatory provisions become effective, or (ii) three years from the date of such deposit in the case of a deposit made after such effective date, only if under such rules and regulations—

(A) within such period not less than 122 per centum of the construction or contract price of the vessel or vessels

is paid or irrevocably committed on account thereof and the plans and specifications therefor are approved by the Secretary of Transportation to the extent by him deemed necessary; and

(B) in case of a vessel or vessels not constructed under the provisions of this title or not purchased from the Secretary of Transportation, (i) said construction is completed, within six months from the date of the construction contract, to the extent of not less than 5 per centum thereof (or in case the contract covers more than one vessel, the construction of the first vessel so contracted for is so completed to the extent of not less than 5 per centum) as estimated by the Secretary of Transportation. and certified by him to the Secretary of the Treasury, and (ii) all construction under such contract is completed with reasonable dispatch thereafter;

(2) for the liquidation of existing or subsequently incurred purchase-money indebtedness to persons other than a parent company of, or a company affiliated or associated with, the mortgagor on a new vessel or vessels within (i) two years from the date of deposit or the date of any extension thereof which may be granted by the Secretary of Transportation pursuant to the provisions of section 511(h), in the case of deposits made prior to the date on which these amendatory provisions become effective, or (ii) three years from the date of such deposit in the case of a deposit made after such effective date.

(h) The Secretary of Transportation is authorized under rules and regulations to be prescribed jointly by the Secretary of the Treasury and the Secretary of Transportation to grant extensions of the period within which the deposits shall be expended or obligated or within which construction shall have progressed to the extent of 5 per centum of completion as provided herein, but such extension shall not be for an aggregate additional period in excess of two years with respect to the expenditure or obligation of such deposits or more than one year with respect to the progress of such construction: Provided, That until January 1, 1965, in addition to the extensions hereinbefore permitted, further extensions may be granted ending not later than December 31, 1965.

(i) Any such deposited gain or portion thereof which is not so expended or obligated within the period provided, or which is otherwise withdrawn before the expiration of such period, or with respect to which the construction has not progressed to the extent of 5 per centum of completion within the period provided, or with respect to which the Secretary of Transportation finds and certifies to the Secretary of the Treasury that, for causes within the control of the taxpayer, the entire construction is not completed with reasonable dispatch, if otherwise taxable income under the law applicable to the taxable year in which such gain was realized, shall be included in the gross income for such taxable year, except for the purpose of the declared value excess-profits tax and the capitalstock tax. If any such deposited gain or portion thereof with respect to a deposit made in any taxable year ending on or before June 30, 1945, is so included in gross income for such taxable year, there shall (in addition to any other deficiency) be assessed, collected,

and paid in the same manner as if it were a deficiency, an amount equal to 1.1 per centum of the amount of gain so included, such amount being in lieu of any adjustment with respect to the declared value excess-profits tax for such taxable year.

(j) Notwithstanding any other provision of law, any deficiency in tax for any taxable year resulting from the inclusion of any amount in gross income as provided by subsection (i), and the amount to be treated as a deficiency under such subsection in lieu of any adjustment with respect to the declared value excess-profits tax, may be assessed or a proceeding in court for the collection thereof may be begun without assessment, at any time: Provided, however, That interest on any such deficiency or amount to be treated as a deficiency shall not begin until the date the deposited gain or portion thereof in question is required under subsection (i) to be included in gross income.

(k) This section shall be applicable to a taxpayer only in respect of sales or indemnifications for losses occurring within a taxable year beginning after December 31, 1939, and only in respect of earnings derived during a taxable year beginning after December 31, 1939.

(1) For the purposes of this section a vessel shall be considered as constructed or acquired by the taxpayer if constructed or acquired by a corporation at a time when the taxpayer owns at least 95 per centum of the total number of shares of each class of stock of the corporation.

(m) The terms used in this section shall have the same meaning as in chapter 1 of the Internal Revenue Code.

(n) The terms "contract for the construction" and "construction contract", as used in this section, shall include, in the case of a taxpayer who constructs a new vessel in a shipyard owned by such taxpayer, an agreement between such taxpayer and the Secretary of Transportation with respect to such construction and containing provisions deemed necessary or advisable by the Secretary of Transportation to carry out the purposes and policy of this section.

(0) The terms "reconstruction and reconditioning", as used in this section, shall include the reconstruction, reconditioning, or modernization of a vessel for exclusive use on the Great Lakes, including the Saint Lawrence River and Gulf, if the Secretary of Transportation determines that the objectives of this Act will be promoted by such reconstruction, reconditioning, or modernization, and, notwithstanding any other provisions of law, such vessel shall be deemed to be a "new vessel" within the meaning of this section for such reconstruction, reconditioning, or modernization. SEC. 512. [46 App. U.S.C. 1162] LIMITATION ON RESTRICTIONS.

Notwithstanding any other provision of law or contract, all restrictions and requirements under sections 503, 506, and 802 applicable to a liner vessel constructed, reconstructed, or reconditioned with the aid of construction-differential subsidy shall terminate upon the expiration of the 25-year period beginning on the date of the original delivery of the vessel from the shipyard.
