Estimated profits.
(2) Estimated profits. For purpose of this paragraph, the term estimated profits means the estimated gross receipts from the sale of recovered wastes reduced by the sum of the (i) estimated average annual maintenance and operating expenses, including utilities and labor, allocable to that portion of the facility which is certified as a treatment facility pursuant to paragraph (a)(1)(i) of this section which produces the recovered waste from which the gross receipts are derived, and (ii) estimated selling expenses. However, in determining expenses to be subtracted neither depreciation nor amortization of the facility is to be taken into account. Estimated profits shall not include any estimated savings to the taxpayer by reason of the taxpayer's reuse or recycling of wastes or other items recovered in connection with the operation of the plant or other property served by the treatment facility.
