(b) To the extent that a fiduciary does not account under Section 19-3A-403 for transactions in derivative instruments, the fiduciary shall allocate to principal receipts from and disbursements made in connection with those transactions.
(c) If a fiduciary grants an option to buy property from the trust, whether or not the trust owns the property when the option is granted, grants an option that permits another person to sell property to the trust, or acquires an option to buy property for the trust or an option to sell an asset owned by the trust, and the fiduciary or other owner of the asset is required to deliver the asset if the option is exercised, then an amount received for granting the option shall be allocated to principal. An amount paid to acquire the option shall be paid from principal. A gain or loss realized upon the exercise of an option, including an option granted to a settlor of the trust for services rendered, shall be allocated to principal.
