The Policy

  1. Principal Investigators must maintain consistency in the manner in which budgets are prepared for proposal submission and funds are budgeted and expenses accounted for after awards are received.

  2. Costs incurred for the same purpose, in like circumstances, must be given consistent treatment in the accounting system in order to comply with CAS 502. That is, each type of cost must be charged consistently as either a direct cost or as part of the F&A rate costs (unrestricted fund).

  3. Unallowable costs must be identified and excluded from any billing, claim, or proposal submitted to the Federal government.

  4. Rates (e.g., service center, F&A) used for estimating, accumulating, and reporting costs must be based on the costs incurred during the University fiscal year.

  5. Research Services is responsible for determining the appropriate treatment of costs and for the maintenance of the CAS Disclosure Statement.
