If the commissioner finds any reasonable cause to believe that a licensee is in an unsafe or unsound condition or is unwilling or unable to pay its payment instruments when they come due, it may require the licensee to deposit funds in a financial institution acceptable to the commissioner in such amounts, for such period, and upon such conditions as the commissioner may specify, and may prohibit the licensee from issuing payment instruments for sale in Utah in an aggregate unpaid amount exceeding the amount of any such required deposit or the amount actually deposited pursuant to such a requirement, whichever is less.
