# 501.602-2 Responsibilities.

(a) Fund sufficiency. A requisition or purchase request signed by an authorized individual is evidence that sufficient money for the purchase is available in the fund cited.

(b) GSA revolving funds. A requisition for indefinite delivery, indefinite quantity contracts requiring a guaranteed minimum quantity must specify enough funds to pay for the guaranteed minimum.

(c) GSA funds, other than revolving funds.

(1) The requisitioning activity must certify that additional funds are available before contract or purchase order award if the purchase exceeds the dollar amount on the requisition by 10percent or $50, whichever is greater.

(2) If a requisition is not used, e.g.,lease of real property, the contracting officer must ensure funds are available before awarding the contract.

(d) Other Federal agencies’ funds. A GSA buying activity must not exceed a fund limitation on a customer agency’s purchase request unless authorized by supply support agreements. If a purchase request indicates insufficient funds to cover all costs, the customer agency must provide additional funds. Regardless of which Central Office or Regional buying activity will make the acquisition, the office initially receiving the requirement requests the additional funds.
