Substantially all our Financing Receivables portfolio is secured lending and we assess the overall quality of the portfolio based on Financing Receivables by airline customer risk rating as defined below. Our internal risk ratings process is an important source of information in determining our allowance for credit losses and represents a comprehensive approach to evaluating risk in our Financing Receivables portfolio. We stratify our Financing Receivables portfolio into three categories: A, B and C. Category A is considered an excellent or high-credit-quality airline customer; Category B is considered a good-credit-quality airline customer; and those airline customers in Category C are considered marginal. An internal risk rating is developed for our airline customers, which is based upon our proprietary model using data derived from the airline customer financial statements and other relevant data points that may impact our airline customer’s ability to honor its financial commitments. The frequency of rating updates is established by our credit risk policy, which requires periodic monitoring and at least an annual review. The latest credit rating review was performed as of December 31, 2025.
