Fair Value Disclosures [Abstract]  
Fair Value Measurements Fair Value Measurements
Fair value is defined as the price that would be received for an asset or paid to transfer a liability in an orderly transaction between market participants on the measurement date. The fair value accounting guidance provides a three-level hierarchy for classifying financial instruments. The levels of inputs used to determine the fair value of our financial assets and liabilities carried on the balance sheet at fair value and for those which only disclosure of fair value is required are characterized in accordance with the fair value hierarchy established by ASC 820, Fair Value Measurements. Where inputs for a financial asset or liability fall in more than one level in the fair value hierarchy, the financial asset or liability is classified in its entirety based on the lowest level input that is significant to the fair value measurement of that financial asset or liability. We use our judgment and consider factors specific to the financial assets and liabilities in determining the significance of an input to the fair value measurements. As of September 30, 2024 and December 31, 2023, only our residual assets related to our securitization trusts, our derivatives, and our investments were carried at fair value on the consolidated balance sheets on a recurring basis. The three levels of the fair value hierarchy are described below:
•Level 1 — Quoted prices (unadjusted) in active markets that are accessible at the measurement date.
•Level 2 — Observable prices that are based on inputs not quoted on active markets but corroborated by market data.
•Level 3 — Unobservable inputs are used when little or no market data is available.
The tables below illustrate the estimated fair value of our financial instruments on our balance sheet. Unless otherwise discussed below, fair values for our Level 2 and Level 3 measurements are measured using a discounted cash flow model, contractual terms and inputs which consist of base interest rates and spreads over base rates which are based upon market observation and recent comparable transactions. An increase in these inputs would result in a lower fair value and a decline would result in a higher fair value. Our Senior Unsecured Notes (as defined below) and Convertible Notes are valued using a market-based approach and observable prices. The receivables held-for-sale, if any, are carried at the lower of cost or fair value, as determined on an individual asset basis.

(1)    Other than the assets for which there is a reserve as discussed in Note 5, loss positions are due to interest rates movements and is not indicative of credit deterioration. We have the intent and ability to hold these investments until a recovery of fair value.
In determining the fair value of our securitization residual assets, we used a market-based risk-free rate and added a range of interest rate spreads of approximately 1% to 6% based upon transactions involving similar assets as of September 30, 2024 and December 31, 2023. The weighted average discount rates used to determine the fair value of our securitization residual assets as of September 30, 2024 and December 31, 2023 were 6.6% and 6.6%, respectively.
Non-recurring Fair Value Measurements
Our financial statements may include non-recurring fair value measurements related to acquisitions and non-monetary transactions, if any. Assets acquired in a business combination, if any, are recorded at their fair value. We may use third-party valuation firms to assist us with developing our estimates of fair value.
Concentration of Credit Risk
Receivables, real estate leases and debt investments consist primarily of receivables from various projects, U.S. federal government-backed receivables, and investment grade state and local government receivables and do not, in our view, represent a significant concentration of credit risk given the large number of diverse offtakers and other obligors of the projects. Additionally, certain of our investments are collateralized by projects concentrated in certain geographic regions throughout the United States. These investments typically have structural credit protections to mitigate our risk exposure and, in most cases, the projects are insured for estimated physical loss, which helps to mitigate the possible risk from these concentrations.
