(2) If a fiduciary receives one or more payments in exchange for part or all of the fiduciary’s interest in an asset-backed security, including a liquidation or redemption of the fiduciary’s interest in the security, the fiduciary shall allocate to income ten percent of receipts from the transaction and ten percent of disbursements made in connection with the transaction, and to principal the balance of the receipts and disbursements.
