Important FBS User Instructions on Use of Accounts

Principal investigators are responsible for providing valid account numbers to core lab managers when requesting services.   Please be sure that the account number meets all of these criteria:

Note for those awaiting awards

If you have received indication that an award will be made, but it has not arrived, please contact your school for advance funding.  With school permission, you may incur costs both for a new award and when you are awaiting a renewal.

Cores  (including vivaria housing) are unable to provide services in the absence of a valid account with adequate and allowable funding.  


It is not acceptable to select accounts arbitrarily, by end dates, or amounts of funds remaining.

In the event that an expense is not allowable, you will be notified of your obligation to transfer funds to an account for which the expense is allowable.

Please note that your dean will be notified when an account is over-spent, and a mandated transfer is not executed, as it will become the school’s obligation to satisfy the over-draft.
