The data inputs of the SAM formula include:

• The budgeted operating subsidies for WMATA by jurisdiction
• The budgeted capital subsidies for WMATA by jurisdiction
• The budgeted local operating deficit for each system
• The budgeted local capital system needs

Those inputs are totaled for each jurisdiction, with the local capital system needs amortized over a 5 year period. The total for each jurisdiction is compared to the total for NVTC to arrive at a percentage, which is applied to the total state operating and capital assistance reimbursements actually received during the fiscal year.

Gas tax revenue is allocated among the jurisdictions using the previous year’s collections on a point of sale basis compared to the NVTC total. That percentage is used to allocate the gas tax received during the fiscal year among the jurisdictions.

95% of WMATA debt service is taken off the top of capital assistance reimbursements as it is received. 5% of the WMATA debt service is taken off the top of the motor fuels tax. These funds are required to be withheld and remitted directly to WMATA by NVTC.

Revenue is taken off the top of the state assistance and gas tax revenue before allocating among the jurisdictions for certain expenses. These include a portion of NVTC’s G&A budget, as reflected in the annual approved budget, and the NTD bus data collection project.

The SAM formula includes several hold harmless mechanisms as explained in the “summary of the resolution #756…” document.

Allocated revenue is held in trust for each jurisdiction for their restricted use for transit purposes. Disbursements from the trust are made by written request by the jurisdiction. These disbursements include payments to WMATA and the local systems for operating and capital needs.
