# 541.401 Monthly and annual review.

(a) Monthly reviews. As an alternative to the requirements outlined in FAR 41.401, which requires monthly reviews of all invoices with annual values exceeding the simplified acquisition threshold, the Comptroller General decision, B-227682.2, August 16, 1989, 68 Comp. Gen. 618 (GAO) authorized GSA to use an alternative methodology to meet this requirement. The GAO decision allows for the use of statistical sampling techniques to pay and audit utility invoices. Specifically, the GAO decision requires analysis and review of any problems discovered through 3% random sampling, 15% out-of-tolerance reports and historical data of utility invoices. Contract files shall include documentation of any corrective actions taken.

(b) Annual reviews. In addition to the requirements of FAR 41.401, the Public Buildings Service (PBS) will provide further guidance for conducting annual reviews.
