prices
(1) (A) The “parity price” for any agricultural commodity, as of any date, shall be determined by multiplying the adjusted base price of such commodity as of such date by the parity index as of such date. (B) The “adjusted base price” of any agricultural commodity, as of any date, shall be (i) the average of the prices received by farmers for such commodity, at such times as the Secretary may select during each year of the ten-year period ending on the 31st of December last before such date, or during each marketing season beginning in such period if the Secretary determines use of a calendar year basis to be impracticable, divided by (ii) the ratio of the general level of prices received by farmers for agricultural commodities during such period to the general level of prices received by farmers for agricultural commodities during the period January 1910 to December 1914, inclusive. As used in this subparagraph, the term “prices” shall include wartime subsidy payments made to producers under programs designed to maintain maximum prices established under the Emergency Price Control Act of 1942. (C) The “parity index”, as of any date, shall be the ratio of (i) the general level of prices for articles and services that farmers buy, wages paid hired farm labor, interest on farm indebtedness secured by farm real estate, and taxes on farm real estate, for the calendar month ending last before such date to (ii) the general level of such prices, wages, rates, and taxes during the period January 1910 to December 1914, inclusive. (D) The prices and indices provided for herein, and the data used in computing them, shall be determined by the Secretary, whose determination shall be final. (E) Notwithstanding the provisions of subparagraph (A) of this paragraph, the transitional parity price for any agricultural commodity, computed as provided in this subparagraph, shall be used as the parity price for such commodity until such date after January 1, 1950 , as such transitional parity price may be lower than the parity price, computed as provided in subparagraph (A) of this paragraph, for such commodity. The transitional parity price for any agricultural commodity as of any date shall be— (i) its parity price determined in the manner used prior to the effective date of the Agricultural Act of 1948, less (ii) 5 per centum of the parity price so determined multiplied by the number of full calendar years (not counting 1956 in the case of basic agricultural commodities) which, as of such date, have elapsed after January 1, 1949 , in the case of non-basic agricultural commodities, and after January 1, 1955 , in the case of the basic agricultural commodities. (F) Notwithstanding the provisions of subparagraphs (A) and (E) of this paragraph, if the parity price for any agricultural commodity, computed as provided in subparagraphs (A) and (E) of this paragraph, appears to be seriously out of line with the parity prices of other agricultural commodities, the Secretary may, and upon the request of a substantial number of interested producers shall, hold public hearings to determine the proper relationship between the parity price of such commodity and the parity prices of other agricultural commodities. Within sixty days after commencing such hearing the Secretary shall complete such hearing, proclaim his findings as to whether the facts require a revision of the method of computing the parity price of such commodity, and put into effect any revision so found to be required. (G) Notwithstanding the foregoing provisions of this section, the parity price for any basic agricultural commodity, as of any date during the six-year period beginning January 1, 1950 , shall not be less than its parity price computed in the manner used prior to October 31, 1949 .
