“Gross receipts” means the gross amounts realized (the sum of money and the fair market value of other property or services received) on the sale or exchange of property, the performance of services, or the use of property or capital (including rents, royalties, interest, and dividends) in a transaction that produces business income, in which the income, gain, or loss is recognized (or would be recognized if the transaction were in the United States) under the Internal Revenue Code , as applicable for purposes of this part. Amounts realized on the sale or exchange of property shall not be reduced by the cost of goods sold or the basis of property sold. Gross receipts, even if business income, shall not include the following items:
(A) Repayment, maturity, or redemption of the principal of a loan, bond, mutual fund, certificate of deposit, or similar marketable instrument.
(B) The principal amount received under a repurchase agreement or other transaction properly characterized as a loan.
(C) Proceeds from issuance of the taxpayer's own stock or from sale of treasury stock.
(D) Damages and other amounts received as the result of litigation.
(E) Property acquired by an agent on behalf of another.
(F) Tax refunds and other tax benefit recoveries.
(H) Contributions to capital (except for sales of securities by securities dealers).
(I) Income from discharge of indebtedness.
(J) Amounts realized from exchanges of inventory that are not recognized under the Internal Revenue Code.
(K) Amounts received from transactions in intangible assets held in connection with a treasury function of the taxpayer's unitary business and the gross receipts and overall net gains from the maturity, redemption, sale, exchange, or other disposition of those intangible assets. For purposes of this subparagraph, “treasury function” means the pooling, management, and investment of intangible assets for the purpose of satisfying the cash flow needs of the taxpayer's trade or business, such as providing liquidity for a taxpayer's business cycle, providing a reserve for business contingencies, and business acquisitions, and also includes the use of futures contracts and options contracts to hedge foreign currency fluctuations. A taxpayer principally engaged in the trade or business of purchasing and selling intangible assets of the type typically held in a taxpayer's treasury function, such as a registered broker-dealer, is not performing a treasury function, for purposes of this subparagraph, with respect to income so produced.
(L) Amounts received from hedging transactions involving intangible assets. A “hedging transaction” means a transaction related to the taxpayer's trading function involving futures and options transactions for the purpose of hedging price risk of the products or commodities consumed, produced, or sold by the taxpayer.
