(1) Every licensee shall maintain records in conformity with generally accepted accounting principles and practices in a manner which will enable the commissioner to determine whether the licensee is complying with the provisions of this article. The record-keeping system of a licensee shall be sufficient if he makes the required information reasonably available. The records need not be kept in the place of business where regulated consumer loans are made, if the commissioner is given free access to the records wherever located. The records pertaining to any loan need not be preserved for more than two years after making the final entry relating to the loan, but in the case of a revolving loan account such two-year period is measured from the date of each entry.
