Columbia University is subject to various types of audits and reviews related to its sponsored projects activities. Various federal, state and private agencies and organizations which provide support for University activities may request an audit, site visit or review (“review”) of a University unit or one of its programs or projects as stipulated in the relevant award agreement. These reviews are in addition to the federal government’s requirement for an annual compliance audit of federally sponsored projects, as per its Office of Management and Budget (OMB) 2 CFR 200, Uniform Guidance (UG) which is managed by the office of the Controller and Treasurer and represent a significant compliance risk for the University. Consistent with many of its compliance functions, the University had developed guidelines for notification of any site visits, reviews and audits of individual awards or programs that PIs and Administrators have been notified of. PIs and Administrators must notify their Senior Business Officer and the Offices of the Controller and Treasurer and Sponsored Projects Administration of review within five business days of receiving the notification from the sponsor to ensure the appropriate level of support can be provided relative to the notification.
