(3) Verification of qualified escrow fund. The attorney general may require at any time from a nonparticipating manufacturer, proof from the financial institution in which the manufacturer has established a qualified escrow fund for the purpose of compliance with the tobacco escrow funds act of the amount of money in the fund, exclusive of interest, being held on behalf of the state, the dates of deposits, and the dates and amounts of all withdrawals from such fund.
