Ten of the fifteen Desk Review projects were selected for evaluation in-depth, primarily through on-site meetings held between March and July 2004. These meetings included as many different parties involved in the individual projects as possible. Each had its own perspective on the project and the role the EIB had played. Typically, they included the Promoter and Provider, their financial advisers, other lenders or EIB guarantors, and the Provider's lead investor. Meetings were also held with the government department responsible for PPP policy to review the project being evaluated in the context of the relevant country's general PPP policy development.
One of the in-depth projects is not located within the EU but was not treated separately due to the developed nature of the country's institutions and financial sector.
