Purchase Cards

In July 2001 and March 2002, GAO testified on significant breakdowns in internal controls over purchase card transactions at two Navy sites that resulted in fraud, waste, and abuse. As a result, the Congress asked GAO to audit purchase card controls at DOD. This report focuses on Air Force purchase card controls and addresses whether the overall management control environment and key internal controls were effective in preventing potentially fraudulent, improper, and abusive purchase card transactions.

Weaknesses in the overall control environment and breakdowns in key controls relied on to manage the purchase card program leave the Air Force vulnerable to fraud, waste, and abuse. Major contributors to the weak control environment included excessive numbers of purchase cards, with about one purchase card for every seven employees, approving official span of control that far exceeded DOD guidelines, and credit limits that were 12 to 20 times higher than actual spending. Of the five key control activities tested, the Air Force had significant control breakdowns in at least three of them (1) receiving of goods and services by someone other than the card holder, (2) cardholder reconciliation, and (3) approving official review of the cardholder's reconciled statements. The highest failure rates--69 to 87 percent--at the four locations tested related to approving official review--viewed by DOD as the first line of defense against misuse of the purchase card. The control breakdowns resulted in purchases that were potentially fraudulent, improper, and abusive or questionable. GAO also identified potentially fraudulent transactions for which supporting documentation was not available to show the quantity and type of items purchased. Air Force officials could not recall the purpose of these transactions. In addition, GAO identified (1) improper transactions related to weaknesses in controls relied on to prevent splitting purchases into multiple transactions to circumvent micropurchase and cardholder transaction limits and (2) the failure to use mandated sources of supply. Finally, GAO found that cardholders who abused or improperly used the purchase card were not subject to strong disciplinary action or consequences. The Air Force has taken a number of steps to improve control over the purchase card program. For example, it implemented automated controls during fiscal year 2002 to help monitor approving official span of control, credit limits, and cardholder reconciliation and approving official review of monthly statements. If effectively implemented, these controls should help strengthen the overall Air Force purchase card control environment as well as controls over statement reconciliation and approval.
