(c) Interest income and other receipts from commercial loans and installment obligations not secured by real or tangible personal property are attributable to this state if the proceeds of the loan are to be applied in Indiana.  If it cannot be determined where the funds are to be applied, the income and receipts are attributable to the state in which the business applied for the loan.  As used in this section, “applied for” means initial inquiry (including customer assistance in preparing the loan application) or submission of a completed loan application, whichever occurs first.

(f) Receipts from the issuance of traveler's checks, money orders, or United States savings bonds are attributable to the state in which the traveler's checks, money orders, or bonds are purchased.

(h) Receipts from the maturity, redemption, sale, exchange, loan, or other disposition of stocks, bonds, notes, options, forward contracts, futures contracts, and similar instruments are attributable to this state if the taxpayer's commercial domicile is in Indiana.  For purposes of this subsection, only the portion of the receipts required to be included in the taxpayer's sales denominator are attributable to Indiana.
