Biosurveillance: DHS Should Reevaluate Mission Need and Alternatives before Proceeding with BioWatch Generation-3 Acquisition

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Homeland Security (DHS) approved the Generation-3 (Gen-3) acquisition in October 2009, but it did not fully engage in the early phases of its acquisition framework to ensure that the acquisition was grounded in a justified mission need and that it pursued an optimal solution. Critical processes in the early phases of DHS's framework are designed to (1) justify a mission need that warrants investment of resources and (2) select an optimal solution by evaluating viable alternatives based on risk, costs, and benefits. BioWatch program officials said that these early acquisition efforts were less comprehensive and systematic than the DHS framework calls for because there was already departmental consensus around the solution. Without a systematic effort to justify the need for the acquisition in the context of its costs, benefits, and risks, DHS has pursued goals and requirements for Gen-3 with limited assurance that they represent an optimal solution. Reevaluating the mission need and systematically analyzing alternatives could provide better assurance of an optimal solution."

Border Patrol: Key Elements of New Strategic Plan Not Yet in Place to Inform Border Security Status and Resource Needs

A letter report issued by the Government Accountability Office with an abstract that begins "In fiscal year 2011, the Department of Homeland Security (DHS) reported data meeting its goal to secure the land border with a decrease in apprehensions; our data analysis showed that apprehensions decreased within each southwest border sector and by 68 percent in the Tucson sector from fiscal years 2006 to 2011, due in part to changes in the U.S. economy and achievement of Border Patrol strategic objectives. These data generally mirrored the decrease in estimated known illegal entries across locations. Other data are used by Border Patrol sector management to assess efforts in securing the border against the threat of illegal migration, drug smuggling, and terrorism; and Border Patrol may use these data to assess border security at the national level as the agency transitions to a new strategic plan. Our analysis of these data indicated that in the Tucson sector, there was little change in the percentage of estimated known illegal entrants apprehended by Border Patrol over the past 5 fiscal years, and the percentage of individuals apprehended who repeatedly crossed the border illegally declined across the southwest border by 6 percent from fiscal years …

Border Security: State Could Enhance Visa Fraud Prevention by Strategically Using Resources and Training

A letter report issued by the Government Accountability Office with an abstract that begins "Certain countries and visa categories are subject to higher levels of fraud. In fiscal year 2010, almost 60 percent of confirmed fraud cases (9,200 out of 16,000) involved applicants from Brazil, China, Dominican Republic, India, and Mexico. Department of State (State) officials told GAO that fraud most commonly involves applicants for temporary visits to the United States who submit false documentation to overcome the presumption that they intend to illegally immigrate. Fraud is also perpetrated for immigrant visas and nonimmigrant visa categories such as temporary worker visas and student visas. In response to State efforts to combat visa fraud, unscrupulous visa applicants adapt their strategies, and as a result, fraud trends evolve over time."

Children's Mental Health: Concerns Remain about Appropriate Services for Children in Medicaid and Foster Care

A letter report issued by the Government Accountability Office with an abstract that begins "An annual average of 6.2 percent of noninstitutionalized children in Medicaid nationwide and 4.8 percent of privately insured children took one or more psychotropic medications, according to GAO's analysis of 2007-2009 data from the Department of Health and Human Services' (HHS) Medical Expenditure Panel Survey (MEPS). MEPS data also showed that children in Medicaid took antipsychotic medications (a type of psychotropic medication that can help some children but has a risk of serious side effects) at a relatively low rate--1.3 percent of children--but that the rate for children in Medicaid was over twice the rate for privately insured children, which was 0.5 percent. In addition, MEPS data showed that most children whose emotions or behavior, as reported by their parent or guardian, indicated a potential need for a mental health service did not receive any services within the same year. The Centers for Medicare & Medicaid Services (CMS) and many states have initiatives under way to help ensure that children receive appropriate mental health treatments. However, CMS's ability to monitor children's receipt of mental health services is limited because CMS does not collect information from states …

Correspondence issued by the Government Accountability Office with an abstract that begins "According to DOD data, over 500,000 passengers used the space-available travel program from fiscal years 2009 through 2011. DOD data show that the five most-used air terminals have limited seats available. Specifically, seats for the three most-traveled destinations from each terminal were near capacity in Fiscal Year 2011. While there were some unused seats for space-available travel, these may be seats on routes with less-desirable destinations or during less-popular travel months. Additionally, DOD officials indicated that existing challenges with usage of the space-available travel program, adherence to DOD's original intent for the program, and air terminal logistics and maintenance would be exacerbated if the number of eligible passengers were to increase."

Correspondence issued by the Government Accountability Office with an abstract that begins "DOD is estimating and publishing approximate costs for selected types of internally and externally required reports, but in some cases its approach is not fully consistent with relevant cost estimating best practices and cost accounting standards. Specifically, DOD entities have been directed to use the cost estimating tool to capture marginal costs of activities associated with completing a report or study that would not have been performed otherwise. These costs consist of certain manpower costs (such as the prorated salaries of military and civilian personnel based on the time they spent) and nonlabor costs (such as contract services, travel, or printing). In comparing DOD’s approach to (1) GAO’s Cost Estimating and Assessment Guide—which states that high-quality, reliable cost estimates should be comprehensive, well documented, and accurate—and (2) relevant accounting standards, we found the following."

Defense Management: The Department of Defense's Annual Corrosion Budget Report Does Not Include Some Required Information

Correspondence issued by the Government Accountability Office with an abstract that begins "In summary, we found that DOD's fiscal year 2013 corrosion budget report to Congress (1) included some, but not all of the six mandated elements; (2) included a funding request that equals DOD's fiscal year 2013 stated requirements for corrosion activities and projects; and (3) lacked information needed to calculate the potential cost avoidance. First, DOD included three of the six mandated elements, did not include two of the elements, and one of the elements was not applicable this year. For example, DOD included the most recent annual corrosion reports of the military departments, attached in an annex. However, it did not include the funds requested in the budget compared to the funding requirements for the fiscal year covered by the report or the previous fiscal year. Second, DOD officials stated that the fiscal year 2013 budget request and the fiscal year 2013 funding requirements for activities and projects are the same this year--$9.1 million. According to these officials, DOD does not have any fiscal year 2013 unfunded requirements for corrosion activities and projects.

Delphi Bankruptcy: Termination of Delphi Pension Plans

Testimony issued by the Government Accountability Office with an abstract that begins "The termination of the six defined benefit plans the Delphi Corporation (Delphi) sponsored, and the provision of benefit protections to some Delphi employees but not others, culminated from a complex series of events involving Delphi, the General Motors Corporation (GM), various unions, the U.S. Department of the Treasury (Treasury), and the Pension Benefit Guaranty Corporation (PBGC). When Delphi spun off from GM in 1999, three unions secured an agreement that GM would provide a retirement benefit supplement (referred to as "top-ups") for their members should their pension plans be frozen or terminated and they were to suffer a resulting loss in pension benefits. These three unions were: (1) the International Union, United Automobile, Aerospace, and Agricultural Implement Workers of America (UAW); (2) the International Union of Electronic, Electrical, Salaried, Machine and Furniture Workers, AFL-CIO (IUE); and (3) the United Steelworkers of America (USWA). No other Delphi employees had a similar agreement to receive a top-up, including salaried workers and hourly workers belonging to other unions. Over the course of events that unfolded over the next decade, the agreements with these three unions ultimately were preserved through the resolution …

DHS Human Capital: Senior Leadership Vacancy Rates Generally Declined, but Components' Rates Varied [Reissued on February 22, 2012]

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Homeland Security’s (DHS) senior leadership vacancy rates, while reaching a peak of 25 percent in 2006, have generally declined since that time—from 25 percent in fiscal year 2006 to 10 percent at the end of fiscal year 2011. From fiscal years 2006 through 2010—the most recent year for which governmentwide vacancy and attrition data were available—DHS vacancy rates in 2006, 2007, and 2010 were statistically higher than the average of other agencies subject to the Chief Financial Officers (CFO) Act but were not statistically different in 2008 and 2009. DHS’s components’—such as the Transportation Security Administration and U.S. Immigration and Customs Enforcement—vacancy rates varied. Many had vacancy rates above 20 percent—one as high as 57 percent—in fiscal year 2006, but generally had lower rates at the end of fiscal year 2011."

Federal Communications Commission: Regulatory Fee Process Needs to Be Updated

A letter report issued by the Government Accountability Office with an abstract that begins "The Federal Communications Commission (FCC) assesses regulatory fees among industry sectors and fee categories based on obsolete data, with limited transparency. The Communications Act requires FCC to base its regulatory fees on the number of full-time equivalents (FTE) that perform regulatory tasks in certain bureaus, among other things. FCC based its fiscal year 2011 regulatory fee assessments on its fiscal year 1998 division of FTEs among fee categories. It has not updated the FTE analysis on which it bases its regulatory fees, in part to avoid fluctuations in fees from year to year. FCC officials stated that the agency has complied with its statutory authority by dividing fees among fee categories based on FTE data—although the data is from fiscal year 1998—since the statute does not prescribe a specific time for FCC to update its FTE analysis. As a result, after 13 years in a rapidly changing industry, FCC has not validated the extent to which its fees correlate to its workload. Major changes in the telecommunications industry include the increasing use of wireless and broadband services and a convergence of telecommunications industries. Moreover, FCC’s practice …

Federal Protective Service: Actions Needed to Assess Risk and Better Manage Contract Guards at Federal Facilities

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Homeland Security’s (DHS) Federal Protective Service (FPS) is not assessing risks at federal facilities in a manner consistent with standards such as the National Infrastructure Protection Plan’s (NIPP) risk management framework, as FPS originally planned. Instead of conducting risk assessments, since September 2011, FPS’s inspectors have collected information, such as the location, purpose, agency contacts, and current countermeasures (e.g., perimeter security, access controls, and closed-circuit television systems). This information notwithstanding, FPS has a backlog of federal facilities that have not been assessed for several years. According to FPS’s data, more than 5,000 facilities were to be assessed in fiscal years 2010 through 2012. However, GAO was unable to determine the extent of FPS’s facility security assessment (FSA) backlog because the data were unreliable. Multiple agencies have expended resources to conduct risk assessments, even though the agencies also already pay FPS for this service. FPS received $236 million in basic security fees from agencies to conduct FSAs and other security services in fiscal year 2011. Beyond not having a reliable tool for conducting assessments, FPS continues to lack reliable data, which has hampered the …

Federal Real Property Security: Interagency Security Committee Should Implement A Lessons-Learned Process

A letter report issued by the Government Accountability Office with an abstract that begins "Based on GAO’s previous work and the information obtained from other agencies, GAO identified eight individual practices that can be combined and considered steps within an overall lessons-learned process—that is, a systematic means for agencies to learn from an event and make decisions about when and how to use that knowledge to change behavior. Not all of the agencies with which GAO spoke used all of the practices, and the application of the practices varied among agencies. For example, to collect information about an incident—the first step of the process—the Bureau of Diplomatic Security within the Department of State collects incident reports, footage from security cameras, and interviews witnesses. To disseminate lessons learned—the fifth step—the Los Angeles Police Department produces a formal document after a critical incident that captures the lessons learned and disseminates the document to its units for use in planning, preparation, and coordination exercises."

Federal Tax Debts: Factors for Considering a Proposal to Report Tax Debts to Credit Bureaus

A letter report issued by the Government Accountability Office with an abstract that begins "At the end of fiscal year 2011, individuals and businesses owed a total of about $373 billion in federal unpaid tax debts--$258 billion in individual debt and $115 billion in business debt. How much of this debt would be suitable to report to credit bureaus could depend on the purpose of the reporting proposal, such as to collect more debts or simply to inform other potential creditors of the existence of tax debts. Most of debts were relatively small in size. Well over half of individuals and businesses with tax debts owed less than $5,000. However, much of the aggregate debt is concentrated among those owing relatively large amounts. Debts over $25,000 add up to a total of $310 billion. Some debts were in the collection process where the Internal Revenue Service (IRS) notifies the taxpayer of the debt and were subject to dispute by the taxpayer, while other debts were covered by installment agreements--about $60 billion of the debts owed were in these two categories. About $110 billion of the total debt was classified by IRS as uncollectable. IRS files tax liens on some tax …

Homeland Security: DHS Has Enhanced Procurement Oversight Efforts, but Needs to Update Guidance

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Homeland Security's (DHS) Office of the Chief Procurement Officer (OCPO) continues to implement and has improved some aspects of its procurement oversight but has not sufficiently updated its guidance. OCPO's oversight has helped ensure that DHS components receive and address constructive assessments of their compliance with procurement regulations and policies. The oversight also has increased the Chief Procurement Officer's visibility into components' progress against procurement-related metrics. For example, OCPO establishes annual procurement goals for the components and tracks their progress in quarterly reports. OCPO has been less consistent in--but continues to hone its implementation of--other aspects of the program, such as self assessments and parts of its acquisition planning reviews. However, until GAO sent DHS a draft of this report recommending that DHS issue updated policy and guidance to reflect changes to the department's procurement oversight efforts, the department did not issue updated policy or guidance. This has led to a lack of clarity among components regarding what the oversight efforts entail. For example, some components did not complete a required self assessment in 2011.

Homelessness: Fragmentation and Overlap in Programs Highlight the Need to Identify, Assess, and Reduce Inefficiencies (open access)

Homelessness: Fragmentation and Overlap in Programs Highlight the Need to Identify, Assess, and Reduce Inefficiencies

A letter report issued by the Government Accountability Office with an abstract that begins "Homelessness programs are fragmented across multiple agencies and some show evidence of overlap. In fiscal year 2010, eight federal agencies obligated roughly $2.8 billion to administer 26 homelessness programs. Three agencies—the Departments of Health and Human Services (HHS), Housing and Urban Development (HUD), and Veterans Affairs (VA)—are responsible for the majority of programs and dollars, 22 of 26 programs, and 89 percent of total funds. GAO found that these agencies and the Department of Labor (Labor) have multiple programs that offer similar services to similar beneficiaries. Fragmentation of services and overlap in some programs is partly due to their legislative creation and partly due to programs evolving to offer services that meet the variety of needs of persons experiencing homelessness. Fragmentation and overlap can lead to inefficient use of resources. For example, both HHS and VA have programs that provide similar services, but each agency separately manages its programs under different administrative units. In addition, some local service providers told us that managing multiple applications and reporting requirements was burdensome, difficult, and costly. Moreover, according to providers, persons experiencing homelessness have difficulties navigating services that are …

First, USAID documents—specifically, the list of projects the agency submitted to Congress— linked only $3.8 million of the $14.8 million in assistance (26 percent) directly to the Ninewa plain region. Second, USAID documents generally did not show whether the projects included minority groups among the beneficiaries of the assistance and specifically whether $8 million of assistance was provided for internally displaced families.

Medicare Program Integrity: CMS Continues Efforts to Strengthen the Screening of Providers and Suppliers

A letter report issued by the Government Accountability Office with an abstract that begins "Medicare claims are screened against enrollment information, using automated enrollment-related prepayment edits, in an effort to prevent improper payments to ineligible providers and suppliers—such as those that are no longer active in the Medicare program or are not properly licensed to provide the services for which they have submitted claims. Officials with the contractors we interviewed described the use of several types of prepayment edits to ensure that claims data are valid. For example, verification edits are intended to check the provider’s National Provider Identifier (NPI), which indicates whether the claim was submitted by an active provider or supplier. However, factors such as the frequency with which contractors have updated provider and supplier enrollment information and limitations of the data used may affect the timeliness and accuracy of data used to screen claims—in turn limiting the ability of the edits to prevent improper payments from occurring. For example, to update information maintained in the Provider Enrollment, Chain and Ownership System (PECOS)—CMS’s centralized database for Medicare enrollment information—the contractors have relied on a variety of data sources that vary in the frequency with which they are updated …

Correspondence issued by the Government Accountability Office with an abstract that begins "PCORI received an unqualified audit opinion on its 2011 and 2010 financial statements. In its audit of PCORI’s financial statements, the IPA found that the financial statements were presented fairly, in all material respects, and there was no reportable noncompliance with selected provisions of laws and regulations the IPA tested as part of its audit. However, the IPA identified a deficiency in PCORI’s internal control over financial reporting related to PCORI reporting on its receipt of appropriated funds. The IPA determined the deficiency to be significant enough to constitute a material weakness. We found no instances in which the IPA did not comply, in all material respects, with U.S. generally accepted auditing standards and generally accepted government auditing standards in the conduct of the financial statement audit. In e-mailed comments from PCORI’s Director of Finance, PCORI stated that the identified deficiency in financial reporting related to appropriations received resulted from uncertainty over differences between the federal government’s and PCORI’s fiscal years and cited action taken to adjust its records to correct the deficiency."
