ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.
Market risk represents the risk of loss that may impact our financial position due to adverse changes in financial market prices and rates. Our market risk exposure is primarily a result of exposure due to potential changes in inflation or interest rates. We do not hold financial instruments for trading purposes.
Interest Rate Risk
Our primary market risk exposure related to our debt is changing interest rates. We had total outstanding debt of $668 million under our short-term revolving facilities at December 31, 2023. Amounts outstanding under our short-term revolving facilities are generally due within one year and bear a variable interest rate of a fixed spread to a prime rate or SOFR. Refer to Note 10 — Debt Instruments of our consolidated financial statements included in Part II, Item 8, "Financial Statements and Supplementary Data," of this Annual Report on Form 10-K for more detail on this variable interest rate. Based on the amounts outstanding, a 100-basis point increase or decrease in market interest rates would result in a change to annual interest expense of $8 million at December 31, 2023. Our interest expense increased by $146 million to $632 million during the year ended December 31, 2023 compared to $486 million during the year ended December 31, 2022, primarily as a result of increased interest associated with the Senior Secured Notes.
Our long-term debt, consisting of our Senior Notes (as defined in Note 10 — Debt Instruments of our consolidated financial statements included in Part II, Item 8, "Financial Statements and Supplementary Data," of this Annual Report on Form 10-K), notes payable, and finance leases have fixed interest rates and terms, and as such, we consider the associated risk to our results of operations from changes in market rates of interest to be minimal.
We are also exposed to interest rate risk arising from market rate adjustments as they pertain to our securitization transactions and variable rate debt borrowings. Future sales of our finance receivables and interest expense may be affected by changes in market rates. We have previously managed these interest rate exposures through the use of derivative instruments such as interest rate swap contracts and cap agreements, and may continue to do so in the future.
Inflation Risk
We are affected by inflationary factors such as decreased vehicle affordability, including as a result of high interest rates, and increases in supply chain and logistics costs, materials costs, and labor costs. We do not believe that inflation has historically had a material effect on our business, financial condition, or results of operations. However, given the current macroeconomic environment and its effect on our results of operations in the year ended December 31, 2023, which were primarily fewer units sold, we will continue to look for ways to manage any changes in consumer purchasing behavior and increased costs, both of which may continue to adversely affect our business, financial condition, and results of operations.
