In a project financing, there are usually several parties carrying out due diligence on the PPP Project from the private sector side: the Private Partner, its sponsors and the lenders, as well as all their advisers. As mentioned in Section E, PPP Contracts in Context, the lenders go through a rigorous process to satisfy themselves that the PPP Project is bankable and this can give the Contracting Authority additional comfort in terms of its own (and its advisers') assessment of the Private Partner's ability to successfully deliver the PPP Project. In a corporate financed PPP Project, this level of third party due diligence may not happen, so the Contracting Authority may have to rely solely on its own (and its advisers') evaluation of the financial and technical robustness of the Private Partner, its bid and its sub-contractors (who may or may not be part of the same corporate group).
