\nIf a trustee determines that an allocation between principal and income required by G.S. 37A-4-409, 37A-4-410, 37A-4-411, 37A-4-412, or 37A-4-415 is insubstantial, the trustee may allocate the entire amount to principal unless one of the circumstances described in G.S. 37A-1-104(c) applies to the allocation. This power may be exercised by a cotrustee in the circumstances described in G.S. 37A-1-104(d) and may be released for the reasons and in the manner described in G.S. 37A-1-104(e). An allocation is presumed to be insubstantial if:\n(1) The amount of the allocation would increase or decrease net income in an accounting period, as determined before the allocation, by less than ten percent (10%); or\n(2) The value of the asset producing the receipt for which the allocation would be made is less than ten percent (10%) of the total value of the trust's assets at the beginning of the accounting period.
