(1) It is the intent of the general assembly that the association consider the payment of interest on any erroneous contribution made to a member contribution account and later refunded to the member. It is the further intent of the general assembly that, if the member was intentionally and actively involved in an erroneous contribution with an intent to increase a retirement benefit by including contributions to the member contribution account that were not based on salary, then interest may be withheld by the association as provided in this section.

(2) The association shall refund to an employer, for payment to a member, any erroneous contribution, as defined in section 24-51-101(21.5), that was made by the employer to a member contribution account. The association shall refund to the employer for payment to such member, in addition to the amount of the erroneous contribution, interest in the amount specified in section 24-51-101(28)(c) for the period beginning on the date of the contribution and ending on the date of the refund; except that, if the member was intentionally and actively involved in the erroneous contribution made to his or her member contribution account, the refund of interest on that amount may be withheld by the association.
