Sec. 24. The term "sales" means:
(1) in the case of the maturity, redemption, sale, exchange, loan, or other disposition of stocks, bonds, notes, options, forward contracts, future contracts, and similar instruments or securities, the net gain from the sale or exchange of such contracts, instruments, or securities;
(2) in the case of the maturity, sale, or exchange of two (2) or more contracts, instruments, or securities as part of a hedging or substantially similar transaction, only the net gains from all such sales or exchanges; and
(3) all other gross receipts of the taxpayer;
not allocated under IC 6-3-2-2(g) through IC 6-3-2-2(k), other than compensation (as defined in section 23 of this chapter), or otherwise provided in this chapter. If a taxpayer does not receive money or other property upon the maturity or redemption of a security, any includible amounts shall not be included unless and until the taxpayer actually receives money or other property. Any reference to "receipts" in this article shall have the same meaning as "sales" unless the context clearly requires otherwise.
