7. SECURITIZED DEBT OBLIGATIONS, NET

We have financed a pool of our loans through a collateralized loan obligation, or the CLO, and have also financed one of our loans through a single asset securitization vehicle, or the Single Asset Securitization. The CLO and the Single Asset Securitization have issued securitized debt obligations that are non-recourse to us. Both the CLO and the Single Asset Securitization are consolidated in our financial statements. Refer to Note 15 for further discussion of our CLO and Single Asset Securitization.
