The GAO found that all loan accounting has been converted from the manual system approved by GAO in 1968, and the implementation problems then identified have been resolved. Full documentation of the new, complex, automated system is warranted to replace the existing loan accounting manual. There is still a need for periodic internal financial audits of the loan program and for regularly recurring independent tests of source data and established procedures. Although the current manual has always provided for semiannual internal check procedures to verify the validity of loan data used by the system, such tests were first performed by AID in 1975. Without adequate internal audit activities, management cannot ensure that its accounting responsibilities are being effectively met.
