Case study of PPP projects in the highway infrastructure shows that the most significant sources of funds and applied financial instruments are sponsors' equity, debt capital in the form of bonds or/and loan and the government assistance of the project. The sponsor is the residual claimant and is essential to the success of the project. Thus, capital costs, as a rule, contain sponsors' equity, which is contributed at an early stage of project implementation. However, there are cases where the debt represents the entire capital of the project, but borrowers require collateral. In the case of highway infrastructure PPP projects, financing the collateral can be represented by different types of guarantee from the government or a financial institute (agency). The government can also be the borrower. For example, in the case of Highway 407 Express Toll Route in Canada, the government chose two consortia for implementation of the project . Both consortia requested government loan guarantees to finance the highway. “Rather than giving guarantees, the government decided to finance the highway by borrowing itself, which it could do at the rates lower than the private sector” . The proposed financial strategy takes into account the component of private capital and public financial support.
