Iowa Admin. Code r. 781-13.14
The treasurer shall be entitled to reimbursement of all of the treasurer's actual and necessary costs and expenses incurred in the administration of Iowa Code chapter 12C and these rules including, but not limited to, legal expenses and administrative expenses. Such costs and expenses shall be reimbursed by withdrawal from the state sinking fund for public deposits in banks wherein a balance, acceptable to the treasurer and sufficient to meet legal and administrative expenses, shall be maintained. In the event at any time funds in the state sinking fund for public deposits in banks are not sufficient to pay any such reimbursement, the treasurer may make an assessment in the manner provided by Iowa Code section 12C.23A, subsection (3d), provided that no such assessment shall exceed the anticipated costs and expenses in the administration of Iowa Code chapter 12C and these rules for a period greater than one year after the assessment is made.
