Financial closure is defined as a stage when all the conditions of a financing agreement are fulfilled prior to the initial availability of funds. Financial closure is attained when all the tie ups with banks/financial institutions for funds are made and all the conditions precedent to initial drawing of debt is satisfied.
In a Public Private Partnership (PPP) project, financial closure indicates the commencement of the Concession Period. The date on which financial closure is achieved is the appointed date which is deemed to be the date of commencement of concession period.
In order to give a uniform interpretation for the term financial closure, Reserve Bank of India has provided the following definition. For Greenfield projects, financial closure has been defined as "a legally binding commitment of equity holders and debt financiers to provide or mobilise funding for the project. Such funding must account for a significant part of the project cost which should not be less than 90 per cent of the total project cost securing the construction of the facility".
