N.M. Stat. § 46-3A-414
Derivatives and options.
(a) As used in this section, "derivative" means a contract or financial instrument or a
combination of contracts and financial instruments which gives a trust the right or
obligation to participate in some or all changes in the price of a tangible or intangible
asset or group of assets, or changes in a rate, an index of prices or rates, or other
market indicator for an asset or a group of assets.
(b) To the extent that a trustee does not account under Section 403 [46-3A-403
NMSA 1978] for transactions in derivatives, the trustee shall allocate to principal
receipts from and disbursements made in connection with those transactions.
(c) If a trustee 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 trustee or other owner of
the asset is required to deliver the asset if the option is exercised, an amount received
for granting the option must be allocated to principal. An amount paid to acquire the
option must 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, must
be allocated to principal.
