One of the key objectives of PPP is to attract private sector funding into the project. In corporate financing, lenders in most cases take assets on the borrower's balance sheet as security for their loans. However, in the case of PPP projects, funding is through project finance arrangements, under which lenders generally rely either exclusively or mainly on the cash flow expected to be generated by the project to recover loans and earn a return on their investments. The arrangement is also popularly known as non-recourse or limited recourse financing.
