Credit risk is the risk of a lessee’s inability or unwillingness to make contractually required payments and to fulfill its other contractual obligations. Market risk reflects the change in the value of financings due to changes in interest rate spreads or other market factors, including the value of collateral underlying financings. Risks associated with exposure to the aviation industry include the risk of a downturn in the commercial aviation industry, which could adversely impact lessee ability to make payments, increase the risk of unscheduled lease terminations and depress lease rates and the value of the Company’s flight equipment. </span></div><div style="margin-top:9pt;text-align:justify;text-indent:24.75pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">We face significant competition and our business may be adversely affected if market participants change as a result of restructuring or bankruptcies, mergers and acquisitions, or new entities entering or exiting the industry. After a sustained period of relatively low inflation rates, rates of inflation increased significantly during the years ended December 31, 2022 and 2023, reaching or exceeding recent historical highs in the United States, the European Union, the United Kingdom, and other countries. While rates of inflation have decreased from their recent highs, they remain above levels of recent years and in some cases above the inflationary targets of the relevant central banks. High rates of inflation may have a number of adverse effects on our business. Inflation may increase the costs of goods, services and labor used in our operations, thereby increasing our expenses. Increased global inflation has contributed to rising interest rates, which may affect our lease revenues, our interest expense, the market value of our interest rate derivatives, and the market value of our flight equipment. </span></div><div style="margin-top:9pt;text-align:justify;text-indent:24.75pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">We are exposed to geopolitical, economic and legal risks associated with the international operations of our business and those of our lessees, including many of the economic and political risks associated with emerging markets.
