(a) Mutual credits and mutual debts shall be set off and only the balance allowed or paid, except that a set-off may not be allowed in favor of a person if:
(1) the obligation of a state trust company to the person on the date the state trust company was closed for liquidation did not entitle the person to share as a claimant in the assets of the state trust company;
(2) the obligation of the state trust company to the person was purchased by or transferred to the person after the date the state trust company was closed for liquidation or for the purpose of increasing set-off rights; or
(3) the obligation of the person or the state trust company is as a trustee or fiduciary.
(b) On request, the receiver shall provide a person with an accounting statement identifying each debt that is due and payable. A person who owes a state trust company an amount that is due and payable against which the person asserts set-off of mutual credits that may become due and payable from the state trust company in the future shall promptly pay to the receiver the amount due and payable. The receiver shall promptly refund, to the extent of the person’s prior payment, mutual credits that become due and payable to the person by the state trust company in liquidation.
