services performed by the project sponsor during the feasibility study. The total credited amount
resulting from in-kind services was estimated at $4b,000. After deducting the credit from in-
kind services, the total non-federal cash contribution to be provided by the project sponsor will
be $465,750.

with the approved PMP. However, management of funds to provide the required technical
products within the authorized budget of the PMP remains the responsibility of the various
functional chiefs. 'The PM's control and managegent of the overall project and study funds
does not relieve the respective chiefs from this responsibility.
