Subject. The article addresses modernization of lending facilities under concession agreements. It is important for evaluating the terms of credit transactions, effectiveness of credit projects, and the concessionaire's ability to repay the loan. Objectives. The purpose is to review the current financing mechanism and underpin approaches to improving the credit facilities within concession agreements. Methods. The study rests on general scientific methods, like the systems and logical analysis and synthesis, principles of induction and deduction, financial calculation techniques. The analytical part employs the balance method, methods of financial coefficients and the method of technical and economic estimates. Results. I analyzed the financial structure and special characteristics of concession agreements, parameters of concessionaires’ activities; considered the types of risks inherent in bank lending under concession agreements, methods for their identification and mitigation; offered a mechanism of lending, including the structure of credit transactions, restrictions for the financial condition of concessionaires, additional requirements and penalties for their non-fulfillment. The findings can help banks define lending parameters for concession agreements. The provided recommendations may be useful for consideration by the authorities of the constituent entities of the Russian Federation. Conclusions. It is possible to reduce the risks of lending under concession contracts, if their terms and conditions are stable, and if the lost income of concessionaires is compensated in the event of early termination. Reasonable tariffs for works and services and increased revenue collection will promote this type of lending.
