Act or prior income tax laws. Where for any taxable year prior to the taxable year 1932 the depletion allowance was based on discovery value or a percentage of income, then the adjustment for depletion for such year shall be based on the depletion which would have been allowable for such year if computed without reference to discovery value or a percentage of income;

(C) in respect of any period prior to March 1, 1913, for exhaustion, wear and tear, obsolescence, amortization, and depletion, to the extent sustained;

(D) in the case of stock (to the extent not provided for in the foregoing subparagraphs) for the amount of distributions previously made which, under the law applicable to the year in which the distribution was made, either were tax-free or were applicable in reduction of basis (not including distributions made by a corporation, which was classified as a personal service corporation under the provisions of the Revenue Act of 1918 or 1921, out of its earnings or profits which were taxable in accordance with the provisions of section 218 of the Revenue Act of 1918 or 1921).

(2) SUBSTITUTED BASIS.—The term "substituted basis" as used in this subsection means a basis determined under any provision of subsection (a) of this section or under any corresponding provision of a prior income tax law, providing that the basis shall be determined

(A) by reference to the basis in the hands of a transferor, donor, or grantor, or

(B) by reference to other property held at any time by the person for whom the basis is to be determined.

Whenever it appears that the basis of property in the hands of the taxpayer is a substituted basis, then the adjustments provided in paragraph (1) of this sub

section shall be made after first making in respect of such substituted basis proper adjustments of a similar nature in respect of the period during which the property was held by the transferor, donor, or grantor, or during which the other property was held by the person for whom the basis is to be determined. A similar rule shall be applied in the case of a series of substituted bases.

SEC. 114. BASIS FOR DEPRECIATION AND DEPLETION.

(a) BASIS FOR DEPRECIATION.-The basis upon. which exhaustion, wear and tear, and obsolescence are to be allowed in respect of any property shall be the adjusted basis provided in section 113 (b) for the purpose of determining the gain upon the sale or other disposition of such property.

(b) BASIS FOR DEPLETION.

(1) GENERAL RULE.-The basis upon which depletion is to be allowed in respect of any property shall be the adjusted basis provided in section 113 (b) for the purpose of determining the gain upon the sale or other disposition of such property, except as provided in paragraphs (2), (3), and (4) of this subsection.

(2) DISCOVERY VALUE IN CASE OF MINES.— In the case of mines (other than metal, eoal or coal, or sulphur mines) discovered by the taxpayer after February 28, 1913, the basis for depletion shall be the fair market value of the property at the date of discovery or within thirty days thereafter, if such mines were not acquired as the result of purchase of a proven tract or lease, and if the fair market value of the property is materially disproportionate to the cost. The depletion allowance under section 23 (m) based on discovery value provided in this paragraph shall not exceed 50 per centum of the net income of the taxpayer (computed without allowance for depletion) from the property upon which the discovery was made, except that in no case shall the depletion allow

ance under section 23 (m) be less than it would be if computed without reference to discovery value. Discoveries shall include minerals in commercial quantities contained within a vein or deposit discovered in an existing mine or mining tract by the taxpayer after February 28, 1913, if the vein or deposit thus discovered was not merely the uninterrupted extension of a continuing commercial vein or deposit already known to exist, and if the discovered minerals are of sufficient value and quantity that they could be separately mined and marketed at a profit.

(3) PERCENTAGE DEPLETION FOR OIL AND GAS WELLS.-In the case of oil and gas wells the allowance for depletion under section 23 (m) shall be 271⁄2 per centum of the gross income from the property during the taxable year, excluding from such gross income an amount equal to any rents or royalties paid or incurred by the taxpayer in respect of the property. Such allowance shall not exceed 50 per centum of the net income of the taxpayer (computed without allowance for depletion) from the property, except that in no case shall the depletion allowance under section 23 (m) be less than it would be if computed without reference to this paragraph.

(4) PERCENTAGE DEPLETION FOR COAL AND METAL MINES AND SULPHUR.-The allowance for depletion under section 23 (m) shall be, in the case of coal mines, 5 per centum, in the case of metal mines, 15 per centum, and, in the case of sulphur mines or deposits, 23 per centum, of the gross income from the property during the taxable year, excluding from such gross income an amount equal to any rents or royalties paid or incurred by the taxpayer in respect of the property. Such allowance shall not exceed 50 per centum of the net income of the taxpayer (computed without allowance for depletion) from the property. A taxpayer making his first return under this title in respect of a property shall state whether he elects to have the

97322-36-6

depletion allowance for such property for the taxable year for which the return is made computed with or without regard to percentage depletion, and the depletion allowance in respect of such property for such year shall be computed according to the election thus made. If the taxpayer fails to make such statement in the return, the depletion allowance for such property for such year shall be computed without reference to percentage depletion. The method, determined as above, of computing the depletion allowance shall be applied in the case of the property for all taxable years in which it is in the hands of such taxpayer, or of any other person if the basis of the property (for determining gain) in his hands is, under section 113, determined by reference to the basis in the hands of such taxpayer, either directly or through one or more substituted bases, as defined in that section. The above right of election shall be subject to the qualification that this paragraph shall, for the purpose of determining whether the method of computing the depletion allowance follows the property, be considered a continuation of section 114 (b) (4) of the Revenue Act of 1934, and as giving no new election in cases where such section would, if applied, give no new election.

SEC. 115. DISTRIBUTIONS BY CORPORATIONS.

DEFINITION OF DIVIDEND.-The term "dividend" when used in this title (except in section 203 (a) (4)(3) and section 207 (c) (1), relating to insurance companies) means any distribution made by a corporation to its shareholders, whether in money or in other property, (1) out of its earnings or profits accumulated after February 28, 1913, or (2) out of the earnings or profits of the taxable year (computed as of the close of the taxable year without diminution by reason of any distributions made during the taxable year), without regard to the amount of the earnings and profits at the time the distribution was made.

(b) SOURCE OF DISTRIBUTIONS. For the purposes of this Act every distribution is made out of earnings or profits to the extent thereof, and from the most recently accumulated earnings or profits. Any earnings or profits accumulated, or increase in value of property accrued, before March 1, 1913, may be distributed exempt from tax, after the earnings and profits accumulated after February 28, 1913, have been distributed, but any such tax-free distribution shall be applied against and reduce the adjusted basis of the stock provided in section 113.

(c) DISTRIBUTIONS IN LIQUIDATION.-Amounts distributed in complete liquidation of a corporation shall be treated as in full payment in exchange for the stock, and amounts distributed in partial liquidation of a corporation shall be treated as in part or full payment in exchange for the stock. The gain or loss to the distributee resulting from such exchange shall be determined under section 111, but shall be recognized only to the extent provided in section 112. Despite the provisions of section 117 (a), 100 per centum of the gain so recognized shall be taken into account in computing net income, except in the case of amounts distributed in complete liquidation of a corporation. For the purpose of the preceding sentence, "complete liquidation" includes any one of a series of distributions made by a corporation in complete cancellation or redemption of all of its stock in accordance with a bona fide plan of liquidation and under which the transfer of the property under the liquidation is to be completed within a time specified in the plan, not exceeding two years from the close of the taxable year during which is made the first of the series of distributions under the plan. In the case of amounts distributed (whether before January 1, 1934, or on or after such date) in partial liquidation (other than a distribution within the provisions of subsection (h) of this section of stock or securities in connection with a reorganization) the part of such distribution which is properly chargeable to capital account shall not be considered a distribution of earnings or profits
