No guaranteed return on investment in pilot road project pitched on Tuesday

According to a source familiar with the project, however, the ministry will not guarantee investors a return on money committed to the Future Fund. That refers to revenue generating by existing Expressway Authority assets that will be transferred to the fund.
“It is a brownfield project [developed land being upgraded or modified], so we don’t guarantee a minimum return,” said the source, speaking on condition of anonymity. An earlier report had suggested the government might guarantee a return of 7-8 per cent on investments.
“If the ministry launches greenfield projects [at undeveloped sites], we may need to guarantee a minimum return,” the source said. 
The ministry aims to raise Bt40 billion to finance the outer-ring Rama III-Dao Khanong expressway and Route 2 East-West motorway.
