Option Value Of Contingent Finance Support In Transportation Public-Private Partnership Projects, Yunping Liang, Baabak Ashuri

Durham School of Architectural Engineering and Construction: Faculty Publications

Uncertainties about construction cost and operational revenues are two major risks in transportation public-private partnership (P3) projects. These uncertainties put projects at risk of being unable to fulfill annual debt repayment obligations. When a project generates insufficient cash flow to service the debt in a certain year, it normally has to go for short-term financing by borrowing short-term loans. With the help of revenue risk-sharing mechanisms, supported projects may be able to get rid of unexpected interest disbursement. The objectives of this paper are twofold: (1) evaluate the refinancing cost of P3 highway projects caused by cash flow shortage and …
