Section 2
SEC. 2. Computation of Extraordinary Gains — The extraordinary gain shall be measured by the difference between the approved wholesale posted prices of refined petroleum products immediately before the authorized price increases and the new posted prices multiplied by the number of units of petroleum products existing as of the day of effectivity of the price increases. Any such profit or gain so determined, shall be deemed realized during the quarter when the authorized price increases occurred. Extraordinary gains shall not only refer to the aggregate increases in the value of crude oil, base stocks and refined petroleum products resulting from the authorized price increases of petroleum products but shall also include the gains accruing to the oil companies as a result of the upward revision of the specific tax rates applicable to said petroleum products.
