Subsequent Events [Abstract]
Subsequent Events	(11) Subsequent Events On April 6, 2026, we amended our two-year revolving credit agreement with Capital One, N.A. to increase the capacity of the facility. The amendment applies to both Capital One, N.A. and the subordinate lender, and increases the capacity of the facility from $167.5 million to $390 million. The revolving period for this facility will extend to October 2027 after which CPS will have the option to repay the outstanding loans in full or to allow them to amortize for an eighteen-month period. On April 22, 2026, we completed our second securitization of 2026. In the transaction, qualified institutional buyers purchased $514.07 million of asset-backed notes secured by $526.17 million in automobile receivables originated by CPS. The sold notes, issued by CPS Auto Receivables Trust 2026-B, consist of five classes. Ratings of the notes were provided by Moody’s and DBRS Morningstar, and were based on the structure of the transaction, the historical performance of similar receivables and CPS’s experience as a servicer. The weighted average interest rate on the notes is approximately 5.51%.
