In any case in which the director finds, upon consideration of a sworn financial statement and through such other investigation as is deemed necessary, that an employer or a former employer who no longer conducts an active business, has insufficient net assets to pay the full amount of all contributions, interest, or penalties that may be due, and where such employer or former employer can pay some but not all of such amount, the director may agree to accept any amount he finds reasonable under the circumstances, as consideration for the settlement of the full amount of contributions, interest or penalties due, if he is satisfied that failure to accept such amount would result in the loss of opportunity to collect any substantial portion of the contributions, interest or penalties. Wherever such an agreement is made there shall be placed in the division‘s files a statement of the full amount of the contributions, interest or penalties, the amount paid as consideration under the terms of the agreement, and the reason for the agreement. Any such agreement shall be final and conclusive as to the matters agreed upon except upon a showing of fraud, or malfeasance, or misrepresentation of a material fact.
