Direct CRA to strengthen its administrative and management procedures for reviewing travel expenses prior to charging NSF awards. Updated procedures could include: • Implementing additional monitoring procedures to ensure that travel credits are posted against the original funding source to which the associated travel expenses were charged. • Implementing additional reviews for all airfare purchases, including requiring the reviewer to verify the traveler purchased an economy-class ticket and/or has appropriate justification for a travel upgrade before charging the travel expense to an NSF award. • Requiring travelers to document the business purpose for all meals provided during collaboration meetings. • Requiring travelers to document the business purpose of each day of a planned trip before purchasing airfare so CRA can evaluate whether it must perform a travel comparison indicating personal travel did not increase airfare costs. • Direct CRA to strengthen its administrative and management processes related to the approval of conference registration fees. Updated processes should require CRA to verify that individuals either have dedicated or will be dedicating effort to an NSF award prior to allowing their conference registration fees to be charged to the NSF award. • Requiring periodic training regarding the types of expenses that are allowable and unallowable for business travel on federal awards. • Requiring the separation of employee and participant meal costs so as not to apply indirect costs to participant support costs.
