August 6, 2004: Congressional Requesters: Subject: Sandia National Laboratories: Further Improvements Needed to Strengthen Controls Over the Purchase Card Program: The Sandia National Laboratories (Sandia) operate in Albuquerque, New Mexico and Livermore, California. Sandia is a government-owned, contractor-operated national laboratory of the Department of Energy's (DOE) National Nuclear Security Administration (NNSA).[Footnote 1] The Lockheed Martin Corporation manages the lab under a cost-reimbursable contract with NNSA. Lockheed Martin is paid a management fee to operate the lab and is reimbursed for all allowable costs charged to the contract. During the fall of 2002, the Federal Bureau of Investigation began investigating two Los Alamos National Laboratory employees for alleged misuse of lab credit cards. Other allegations of theft and misuse of government funds at Los Alamos soon followed. In light of the problems identified at Los Alamos, you asked us to review selected procurement and property management practices at two DOE and two NNSA contractor labs, including Sandia.[Footnote 2] This report summarizes the information provided during our June 14, 2004 briefing to your staff on these issues as they relate to Sandia. The enclosed briefing slides highlight the results of our work and the information provided.[Footnote 3] Specifically, we reviewed Sandia's purchase card program and property management practices to determine whether (1) internal controls over the lab's purchase card (Pcard) program provided reasonable assurance that improper purchases would not occur or would be detected in the normal course of business, (2) purchase card expenditures made under the contract properly complied with lab policies and other applicable requirements and were reasonable in nature and amount and thus were allowable costs payable to the contractor under the contract, and (3) property controls over selected asset acquisitions provided reasonable assurance that accountable assets would be properly recorded and tracked.[Footnote 4] Our review covered selected transactions that occurred during fiscal year 2002 and the first half of fiscal year 2003 (October 1, 2001, through March 31, 2003), which were the most current data available when we requested the data for our review. This report also includes 10 recommendations for action--9 related to actions needed to be taken by Sandia and 1 related to action needed to be taken by the NNSA contracting officer for Sandia. Results in Brief: Internal control weaknesses in Sandia's Pcard program increased the lab's risk of improper purchases. These control weaknesses primarily related to the review and approval processes, which are key controls in the Pcard program. Specifically, during the majority of our review period, cardholders who were managers were allowed to approve their own purchases. Of the nonstatistical selection of 141 transactions obtained through data mining[Footnote 5] for fiscal years 2002 and the first half of fiscal year 2003, 15 purchases (11 percent) were made by such cardholders and thus did not have any independent review and approval. In addition, approving officials did not review cardholders' monthly statements in a timely manner for 14 of 49 (29 percent) transactions tested.[Footnote 6] For example, one purchase of a digital camera wasn't approved until 16 months after purchase. We also found 7 of the 141 nonstatistically selected transactions lacked an invoice, credit card slip, or other sales documentation. This may partly be due to the fact that lab policy did not require monthly approvers to verify purchases listed in the cardholder statements against supporting documents. We further found that Sandia required purchases of restricted items to be preapproved, but did not require documentation of such approvals for the majority of our review period. Thirty-one of the 36 (86 percent) restricted item purchases we reviewed totaling $92,857 did not have any documented preapproval. Consequently, neither we nor the lab could determine whether this control was being effectively implemented. These control weaknesses likely contributed to the approximately $479,645 in improper, wasteful, and questionable purchases we identified during our review. While relatively small compared to the approximately $102 million in purchase card activity that occurred during the review period, it demonstrates vulnerabilities from weak controls that could be exploited to a greater extent. Specifically, we found 10 improper split purchases--that is, groups of two or more similar transactions that were split to circumvent single purchase limits--consisting of 24 transactions totaling $372,321. Eleven purchases totaling $3,606 we determined to be wasteful because they were excessive in cost compared to other alternatives and/or of questionable need, such as four laser pointers costing $228 each, when other laser pointers were available for $90-$120 each. Another 15 transactions totaling $103,718 we considered questionable because they were missing key documentation that would enable us or the lab to determine what was purchased and whether the purchases were proper and reasonable. Because we only tested a small portion of the transactions we identified that appeared to have a higher risk of fraud, waste, or abuse, there may be other improper, wasteful, and questionable purchases in the remaining untested transactions. Sandia also did not ensure that acquired property and equipment were tracked properly and in a timely manner. Of 43 assets in our nonstatistical selection of Pcard transactions, 21 (49 percent) totaling $39,113 were not recorded in Sandia's property management system at the time we provided the lab with the list of assets selected. We performed a physical observation of 88 assets, which included selected assets identified from the nonstatistical selection of 141 Pcard transactions as well as assets selected from the property database because they were still assigned to separated employees or there were multiple assets with the same serial number. All 88 were either found or--in the case of 12 assets--the lab indicated that the items had been disposed of or written off. However, because they only record the bar-code number and not the asset's serial number on the disposal form or the write-off report, we could not verify that the 12 assets had actually been disposed of or written off. Furthermore, our physical observation revealed several inaccuracies in the property database, including data discrepancies, incorrect location information, and inaccurate property custodians listed. The lab has made a number of recent policy and procedural changes that, if properly implemented, should help improve internal controls over its Pcard purchases. However, additional improvements are needed to further reduce the risk of improper and wasteful purchases. Recommendations for Executive Action: In order to address the issues identified in our review, we recommend that the Administrator of NNSA direct the Sandia National Laboratories' Director to take the following nine actions. * To strengthen internal controls over the purchase card program and reduce the lab's exposure to improper, wasteful, and questionable purchases: * Cancel purchase card accounts for cardholders who perform oversight functions for the purchase card program to help ensure appropriate independence and separation of duties between these functions. * Require approving officials to attend initial and periodic refresher training on Pcard policies and procedures to help ensure their knowledge of purchasing requirements remains current. * Emphasize during training for cardholders and approving officials the laboratory's policies on (1) timely cardholder reconciliation and supervisory review of transactions, (2) split purchases, (3) transaction documentation requirements, (4) preapproval requirements for restricted items, (5) prohibited purchases, and (6) considering best value in making and approving purchases. Training should also include reminding these staff of the criteria for accountable assets and the requirements to notify property management to ensure accountable assets purchased are identified, bar-coded, and entered into the property management system. * Require approving officials to verify purchases on cardholders' monthly statements to the detailed sales receipts, invoices or other independent support showing the description, quantity, and price of individual items for all purchases made to help ensure that purchases are adequately documented and are proper purchases before approving. This should include verifying that there is documented approval for all purchases of restricted items. * Implement tools, such as data mining, for use by Pcard program staff in reviewing cardholder purchases for improper purchases. These tools should be used to systematically monitor for potential split purchases, unusual vendors, restricted items without approval, and other potentially improper or wasteful purchases. * Consider modifying the Pcard system so that purchases that are not reconciled timely by the cardholder are charged to a temporary suspense account rather than to each cardholder's default project and task codes. * To help improve Sandia's controls over the purchasing, recording, and safeguarding of assets, we recommend the following. * Require that key information such as the property custodian, location, serial number, and item description are verified against the information entered into the property database during physical inventory counts. * Develop a report to enable property management staff to review recent Pcard purchases for accountable assets that require recording in the property management system. * Require that serial numbers for items being disposed or written off be listed on the disposal forms or inventory write-off reports. We also recommend that the Administrator of NNSA direct the NNSA contracting officer for the lab to review the improper, wasteful, and questionable items we identified to determine whether any of these purchases should be repaid to NNSA. Agency Comments: We obtained comments on a draft of this briefing from NNSA headquarters officials. They generally agreed with the findings and recommendations, and indicated that the lab has made a number of improvements to their controls in light of the problems identified at Los Alamos. We also obtained comments from NNSA's Sandia Site Office, who disagreed with the recommendation to require approving officials to verify purchases listed on cardholders' statements against detailed sales receipts or invoices, indicating that to do so would be labor intensive and cost prohibitive. They suggested periodic reviews of statistical samples and data mining instead. While we endorse periodic reviews of sample transactions and data mining as part of an overall system of internal control, they are not a substitute for adequate supervisory review. The approving official's review of transactions is one of the most critical controls for helping to ensure that purchases are necessary and proper. Without reviewing independent, detailed support for the individual items purchased, a reviewer cannot ensure that the actual items purchased were reasonable and proper, thus increasing the risk of improper purchases. Lab officials indicated that their efforts over the past 18 months have resulted in many process and internal control changes, and further changes are being considered. For example, Sandia management is considering making training for approving officials mandatory and is looking into the purchase of data mining software. In addition, the Pcard manager informed us that the account of the staff member responsible for monitoring Pcard activities was cancelled on June 8, 2004. The lab also provided technical and clarifying comments, which we incorporated as appropriate. Scope and Methodology: To determine if Sandia's internal controls over its Pcard program provided reasonable assurance that improper purchases would not occur or would be detected in the normal course of business, we reviewed Sandia's contract with NNSA and applicable provisions of the DOE Acquisition Regulation (DEAR) and the Federal Acquisition Regulation (FAR), performed walkthroughs of key processes, interviewed Sandia and NNSA management and staff, and compared the results to the lab's policies and GAO's Standards for Internal Control in the Federal Government.[Footnote 7] These standards provide the overall framework for establishing and maintaining internal control and for identifying and addressing major performance and management challenges and areas at greatest risk of fraud, waste, abuse, and mismanagement and are based on internal control guidance for the private sector.[Footnote 8] To determine whether Pcard expenditures complied with lab policies and other applicable requirements and were reasonable in nature and amount, we performed data mining on fiscal year 2002 and the first half of fiscal year 2003 Pcard transactions to identify indicators of potential noncompliance with policies and procedures and to identify purchases that appeared to be from unusual vendors, purchases made on weekends, during the holidays, or at fiscal year-end, and purchases of attractive assets. Based on the results, we (1) identified 50 potential split purchases and tested all of them to determine whether they were in fact split purchases and (2) tested a nonstatistical selection of 141 transactions for evidence of supervisory review and approval, adequacy of supporting documentation, and reasonableness of the purchases. To determine if property controls over selected asset acquisitions provided reasonable assurance that accountable assets would be properly recorded and tracked, we performed walkthroughs to observe property controls, reviewed property management policies and procedures, tested accountable property items selected in the nonstatistical selection to determine whether these assets had been entered into the lab's property system prior to our review, performed data mining on the property database to identify possible database errors or inaccuracies such as property assigned to terminated employees and multiple property items with the same serial number, and performed a physical observation of selected assets to determine whether they could be properly accounted for. We requested oral comments on a draft of the enclosed briefing slides from the Administrator of NNSA or his designee and have included any comments as appropriate in the letter and enclosed slides. While we identified some improper, wasteful, and questionable purchases, our work was not designed to determine the full extent of such purchases. We conducted our work on all four labs from March 2003 through May 2004 in accordance with generally accepted government auditing standards.

As part of its national security mission, NNSA has responsibility for the institutional stewardship of three national security laboratories. [2] The four labs we reviewed were DOE's Lawrence Berkeley National Laboratory and Pacific Northwest National Laboratory, and NNSA's Lawrence Livermore National Laboratory and Sandia National Laboratories. [3] Separate briefings were provided for each of the labs reviewed, which we also summarized in separate letters. [4] Throughout this document, references to purchases and transactions refer to those made by the contractor employees of the lab that are charged to the NNSA contract. Although the lab's purchase cards are issued by the contractor, purchases charged to the NNSA contract are ultimately reimbursed and thus paid for by the federal government. Similarly, property purchased that is charged to NNSA becomes government property. [5] Data mining applies a search process to a data set, analyzing for trends, relationships, and interesting associations. For instance, it can be used to efficiently query transaction data for characteristics that may indicate potentially improper activity. [6] We were unable to test the timeliness of supervisory approval for the remaining 92 transactions selected. According to Sandia officials, during a computer conversion all of the approval dates were changed to December 23, 2002. Thus, we could only perform this test on transactions that occurred after the conversion.
