Section 2228 - Extension of credit(a) Any licensee may, subject to any limitations on lending authority contained in its charter or otherwise imposed by law and subject to the other provisions of this subchapter, offer and extend closed end credit to a borrower and, in connection therewith, may charge and collect the interest and other charges permitted by this subchapter and may take such security as collateral in connection therewith as may be acceptable to the licensee. Loans to any 1 borrower may not exceed 20% of the paid-in capital stock and surplus of such lender.(b) All licensees will maintain records or other comparable evidence of their activity taken to reach a decision on a loan. If a commitment between a licensee and an applicant is not met (regardless of whether a similar loan at a higher rate is closed or not) and the delay is the licensee's fault, or the licensee cannot demonstrate through its records or other comparable evidence that it took reasonably diligent steps to meet its deadline, such action or inaction taken by the licensee may be deemed to be an unsafe and unsound operating practice. In such a case, the Commissioner shall take appropriate action which may include, but is not limited to, an order to refund certain fees paid by the applicant to the licensee.66 Del.
