20 C.F.R. § 662.270
The MOU must describe the particular funding arrangements for services and operating costs of the One-Stop delivery system. Each partner must contribute a fair share of the operating costs of the One-Stop delivery system proportionate to the use of the system by individuals attributable to the partner's program. There are a number of methods, consistent with the equirements of the relevant OMB circulars, that may be used for allocating costs among the partners. Some of these methodologies include allocations based on direct charges, cost pooling, indirect cost rates and activity-based cost allocation plans. Additional guidance relating to cost allocation methods may be issued by the Department in consultation with the other appropriate Federal agencies.
