(1) If any part of the principal consists of a right to receive royalties, overriding or limited royalties, working interests, production payments, net profit interests, or other interests in minerals or other natural resources in, on, or under land, the receipts from taking the natural resources from the land shall be allocated as follows:

(a) If received as rent on a lease or extension payments on a lease, the receipts are income;

(b) If received from a production payment, the receipts are income to the extent of any factor for interest or its equivalent provided in the governing instrument. There shall be allocated to principal the fraction of the balance of the receipts that the unrecovered cost of the production payment bears to the balance owed on the production payment, exclusive of any factor for interest or its equivalent. The receipts not allocated to principal are income.

(c) If received as a royalty, overriding or limited royalty, or bonus, or from a working, net profit, or any other interest in minerals or other natural resources, receipts not provided for in paragraph (a) or (b) of this subsection (1) shall be apportioned on a yearly basis in accordance with this paragraph (c) regardless of whether any natural resource was being taken from the land at the time the trust was established. Fifteen percent of the gross receipts, but not to exceed fifty percent of the net receipts remaining after payment of all expenses, direct and indirect, computed without allowance for depletion, shall be added to principal as an allowance for depletion. The balance of the gross receipts after payment therefrom of all expenses, direct and indirect, is income.

(2) If a trustee, on April 22, 2009, held an item of depletable property of a type specified in this section, he or she shall allocate receipts from the property in the manner used before April 22, 2009, but as to all depletable property acquired after April 22, 2009, by an existing or new trust, the method of allocation provided herein shall be used.

(3) This section does not apply to timber, water, soil, sod, dirt, turf, or mosses.
