What are the provisions regarding the disbursement of the 20% national funding?
It is stated that the National Contribution to the expenses will be covered by national funding from the State and/or other contributions (local or own funding).
I understand that for public entities (beneficiaries of categories (a) and (b), as I mentioned in the above question (2)), in Greece, the 20% contribution comes from the Public Investment Programme (PIP), while for private entities (categories (c) to (e)) it comes from own resources/funding.
As for Bulgaria, this will be determined by their legislation (according to page 100 of the PIM, it appears to be under definition), through their national mechanisms and procedures.
