(a) There shall be paid to the Commissioner by every corporate fiduciary including each trust company, bank, savings and loan association, and savings bank to which this Act shall apply, reasonable fees that the Commissioner shall assess to recover the costs of administration, certification, examination and supervision of trusts authorized under this Act.
     (b) In addition to the fees authorized in subsection (a) of this Section the Commissioner shall assess reasonable receivership fees and establish a Non-insured Institutions Receivership account in the Bank and Trust Company Fund to provide for the expenses that arise from the administration of the receivership of a corporate fiduciary under this Act. The aggregate of such assessments shall be paid into the Non-insured Institutions Receivership account in the Bank and Trust Company Fund. The assessments for this account shall be levied until the sum of $4,000,000 has been deposited into the account from assessments authorized herein, whereupon the Non-insured Institutions Receivership account assessment shall be abated. If a receivership of a corporate fiduciary under this Act requires expenditures from this account, assessments may be reinstituted until the balance in the Non-insured Institutions Receivership account arising from assessments is restored to $4,000,000.
     (c) The Commissioner may, by rule, establish a reasonable manner of assessing the receivership assessments under this Section.
