  1. GAO's Forensic Audits and Investigative Service Team: Tools and Methods to Identify Fraud, Waste and Abuse National State Auditors Association Annual Conference June 15, 2011 Gregory D. Kutz, Director

  2. Discussion Agenda • FAIS Background • FAIS Methodology • Case Study Discussion • Questions

  3. FAIS BackgroundWho We Are • The Government Accountability Office (GAO) is a federal agency that reports to Congress and the American people. • Over time, GAO found that its ability to investigate fraud was enhanced when auditors/analysts worked closely with criminal investigators: • Auditors/analysts benefit from law enforcement background of criminal investigators • Criminal investigators benefit from analytical and database experience of auditors/analysts • Combining disciplines improved GAO’s ability to deliver high-impact reports and testimonies to Congress.

  4. FAIS BackgroundWho We Are • The Forensic Audits and Investigative Service (FAIS) team brings GAO’s related anti-fraud and other investigative activities together in one organization. • In addition to analysts, forensic auditors, and criminal investigators, FAIS staffing includes: • data mining and systems integration experts, • fraud hotline analysts, and • quality control staff such as communications analysts. • All permanent FAIS staff are Certified Fraud Examiners (CFE).

  5. FAIS BackgroundWhat We Do • FAIS work addresses • fiscal challenges facing our nation, • organizational and individual ethics, • stewardship over government resources, and • control environment at federal agencies. • FAIS work comes from a variety of sources • congressional requests, • Comptroller General Authority (self-initiated), and • hotline tips.

  6. FAIS BackgroundWhat We Do • FAIS has governmentwide jurisdiction and has access to most government data including tax records, SSA data, and grants and disbursement data, including Medicare/Medicaid data. • FAIS has access to law enforcement tools such as the National Criminal Information Center (NCIC), Financial Crimes Enforcement Network (FINCEN), and Lexis-Nexis law enforcement. • FAIS also manages FraudNet, the governmentwide hotline to report fraud, waste, and abuse. • FAIS has offices in Washington, D.C., and Dallas, Texas.

  7. FAIS MethodologyOverview • FAIS’s forensic audits attempt to identify the reason why fraud or abuse has occurred. Where possible, we estimate the magnitude of the problem. • Investigations are more limited in scope and provide the facts and details that substantiate fraud or demonstrate a vulnerability. • FAIS’s best antifraud work leverages both forensic audit and investigative approaches to deliver a powerful message about broken controls.

  8. FAIS MethodologyTechniques and Tools • Audit steps • Data matching • Data mining • Statistical sampling • Internal controls evaluation Integration • Investigative steps • Proactive testing • Social engineering • Coordination with IGs or other law enforcement agencies • NCIC, FINCEN, Lexis Nexis law enforcement • Combined forensic audit and investigation • Concludes on broken controls • Substantiates specific fraud cases and/or provides first-hand evidence of fraud • Where possible identifies magnitude

  9. FAIS MethodologyData Matching • Data matching involves comparing two discreet data sets to identify questionable overlaps. • Governmentwide access to federal databases allows FAIS to perform matching on data sets that other federal agencies do not have the authority to perform. • This is an audit step that reveals fraud indicators that require further investigation, for example: • Commercial drivers also on 100 percent disability • Prisoners who also received disaster assistance • ARRA Recipients with unpaid federal taxes

  10. FAIS MethodologyData Mining • Data mining is an effective way to develop fraud targets for further investigation. • FAIS mines databases for • Specific types of transactions • Patterns within the data • Outliers (e.g., doctor shopping for controlled substances) • Based on interviews of targets, gather additional intelligence to refine data mining (“James Fine Dining” example).

  11. FAIS MethodologyProactive Testing • FAIS also has the authority to perform proactive testing of programs or processes to identify vulnerabilities. • Proactive tests performed by criminal investigators as “red team” exercises (e.g. no agency notification). • Tests allow FAIS to gather first-hand knowledge of control breakdowns and vulnerabilities in a realistic setting, rather than rely on the representations of the tested entity. • Analyst/auditors help interpret the results of the tests in a broader context and provide planning input.

  12. FAIS MethodologyCase Studies • Case studies help illustrate the details and impact of fraud in concrete terms to Congress and taxpayers. • Criminal investigators are critical to developing cases: • Access to law enforcement databases and resources • Professional interviewing skills • Contacts in other federal agencies and IGs. • FAIS frequently refers case studies to the appropriate law enforcement agency or other entity for further investigation.

  13. FAIS MethodologyStandards • Forensic audits are performance audits conducted in accordance with generally accepted governmental auditing standards • Certain elements of work in FAIS are done under the Council of Inspectors General for Integrity and Efficiency (CIGIE) Investigative standards • E.g., field investigations of cases of procurement fraud

  14. Questions? Any questions prior to moving on to case study discussion?

  15. FAIS Case Study #1Passport Fraud • Undercover tests to obtain genuine U.S. passports using counterfeit or fraudulently obtained documents • Used commercial, off-the-shelf hardware and software to create counterfeit birth certificates and driver’s licenses • Applied in person at U.S. Postal Service facilities and, in one case, a Department of State office • Used identities (names and SSNs) that would simulate identity theft

  16. FAIS Case Study #1Passport Fraud • Findings: • Neither the U.S. Postal Service nor the Department of State detected counterfeit documents • All four applications were successful, including: • Passport issued to a man who died in 1965 • Passport issued to a 53-year-old applicant using the name and SSN of a 5-year-old child • All passports issued to the same criminal investigator • State and the FBI have identified fugitives, sex offenders, and delinquent taxpayers who used identity theft to obtain genuine U.S. passports

  19. FAIS Case Study #2Medicaid Controlled Substance Fraud and Abuse • GAO found tens of thousands of Medicaid beneficiaries and providers involved in potentially fraudulent and abusive purchases of controlled substances in FY 2006 and 2007 • Doctor Shopping - about 65,000 Medicaid beneficiaries in five states acquired the same type of controlled substance from six or more doctors at a cost of $63 million. • Although some beneficiaries justifiably received this medication,others obtained these drugs to support their addictions or sell on the street.

  20. FAIS Case Study #2Medicaid Controlled Substance Fraud and Abuse • Other Findings: • $2 million in controlled substance prescriptions were written or filled by medical practitioners and pharmacies barred or excluded from federal healthcare programs for such offenses as illegally selling controlled substances. • Our analysis also found that controlled substance prescription claims to over 1,800 beneficiaries were filled after they died at a cost of $200,000. • In addition, our analysis also found that Medicaid paid about $500,000 in Medicaid claims based on controlled substance prescriptions “written” by over 1,200 doctors after they died.

  21. FAIS Case Study #2Medicaid Controlled Substance Fraud and Abuse • States are primarily responsible for the fight against Medicaid fraud. The five selected states we examined, however, did not have a comprehensive framework to prevent fraud and abuse of controlled substances. • The Centers for Medicare and Medicaid Services is responsible for overseeing state fraud and abuse control activities but has provided limited guidance related to controlled substances.

  22. FAIS Case Study #3: Head StartFraud and Abuse at Selected Centers Received hotline allegations involving two nonprofit grantees • Manipulating recorded income to qualify higher income applicants • Encouraging families to report that they were homeless when they were not • Enrolling more than 10 percent of over-income children • Counting children as enrolled in more than one center at a time

  23. FAIS Case Study #3: Head StartFraud and Abuse at Selected Centers Realizing such schemes could be widespread, we • Developed 15 undercover test scenarios at centers in 6 states and the District of Columbia • Attempted to register fictitious children using bogus documents • Interviewed families on wait lists to document cases of potentially eligible children not receiving services due to others’ fraudulent activity

  24. FAIS Case Study #3: Head StartFraud and Abuse at Selected Centers • For 8 of 15 proactive tests, staff at Centers fraudulently misrepresented information to register over-income children into under-income slots • These tests were done in 6 states and D.C. • None of information provided was verified leaving program vulnerable to falsified earnings statements and other documents

  25. FAIS Case Study #3: Head StartFraud and Abuse at Selected Centers 506 of the 550 Head Start centers contacted had wait lists • 2 centers where we enrolled fictitious children later became full and developed wait lists after the fictitious children had been withdrawn • Many families stated that their incomes were at or below the federal poverty level • Some families stated they had experienced domestic violence, or were receiving some type of public assistance, a group automatically eligible for Head Start

  26. FAIS Case Study #4: ARRA Recipients With Unpaid Federal Taxes • To determine the magnitude of known federal tax debt owed by Recovery Act contract and grant recipients • Matched contract and grant recipients from www.recovery.gov to IRS Unpaid tax assessments @ September 30, 2009 • Developed examples of entities with unpaid federal taxes that benefited from Recovery Act contracts and grants through July 2010 reporting • Focused on 15 cases of entities with substantial unpaid payroll taxes

  27. FAIS Case Study #4: ARRA Recipients With Unpaid Federal Taxes • At least 3,700 Recovery Act contract and grant recipients (including prime recipients, subrecipients, and vendors) with $750 million of unpaid federal taxes • These entities received $24 billion of Recovery Act funds through July of 2010 • Represents about 6% of the 63,000 Recipients with taxpayer identification numbers that we could derive • Understated for • 17,000 Recipients with no TIN • Underreporting of income • Non-filing of required tax returns

  28. FAIS Case Study #4: ARRA Recipients With Unpaid Federal Taxes • 15 cases included • Construction • Engineering • Security • Health Care • IRS had taken collection or enforcement action for all 15 cases • For 13 IRS had filed federal tax liens • For 12 IRS had assessed Trust Fund Recovery Penalties against owners and officers

  29. FAIS Case Study #4: ARRA Recipients With Unpaid Federal Taxes • For 15 Cases • Over half had reported state and local tax liens • Several defaulted on installment agreements • Several failed to file required tax returns • Several cited for Federal Labor Law Violations • Several owners and officers received substantial salaries and company loans • Several owners had hundreds of thousands of dollars each in gambling transactions • Several entities received millions of additional federal dollars of non-Recovery Act contracts

  30. FAIS Case Study #4: ARRA Recipients With Unpaid Federal Taxes • Potential Solutions • Further controls to prevent entities with significant unpaid federal taxes from receiving new awards • Additional sharing of IRS information for limited purposes • Steps to address sub-recipients with unpaid federal taxes • Enhancements in Federal Payment Levy Program

  31. Summary of Key Points • There are significant benefits to establishing and maintaining an integrated team of auditors, analysts, and investigators. • Data mining and matching are effective tools to help identify fraud and abuse. • Developing actual cases of fraud and abuse helps show the actual effect of ineffective controls. • It is important to perform internal controls work and develop practical solutions to minimize fraud, waste and abuse.
