Interstate Compacts: Transparency and Oversight of Bi-State Tolling Authorities Could Be Enhanced

A letter report issued by the Government Accountability Office with an abstract that begins "Bi-state tolling authorities have broad authority to set toll rates and use revenues for a range of purposes, including maintaining, repairing, and improving their infrastructure. In setting tolls, bi-state tolling authorities are primarily influenced by debt obligations and maintain specific operating revenues to repay their debt. A federal statute requiring bridge tolls to be "just and reasonable" has less influence on tolling decisions, in part, because no federal agency has authority to enforce the standard."

Medicare Physician Payment: Care Coordination Programs Used in Demonstration Show Promise, but Wider Use of Payment Approach May Be Limited

A letter report issued by the Government Accountability Office with an abstract that begins "Congress mandated in 2000 that the Centers for Medicare & Medicaid Services (CMS) conduct the Physician Group Practice (PGP) Demonstration to test a hybrid payment methodology for physician groups that combines Medicare fee-for-service payments with new incentive payments. The 10 participants, with 200 or more physicians each, may earn annual bonus incentive payments by achieving cost savings and meeting quality targets set by CMS in the demonstration that began in April 2005. In July 2007, CMS reported that in the first performance year (PY1), 2 participants earned combined bonuses of approximately $7.4 million, and all 10 achieved most of the quality targets. Congress mandated that GAO evaluate the demonstration. GAO examined, for PY1, the programs used, whether the design was reasonable, and the potential challenges in broadening the payment approach used in the demonstration to other physician groups. To do so, GAO reviewed CMS documents, surveyed all 10 groups, and conducted interviews and site visits."

Critical Infrastructure Protection: Key Private and Public Cyber Expectations Need to Be Consistently Addressed

A letter report issued by the Government Accountability Office with an abstract that begins "Pervasive and sustained computer-based attacks pose a potentially devastating impact to systems and operations and the critical infrastructures they support. Addressing these threats depends on effective partnerships between the government and private sector owners and operators of critical infrastructure. Federal policy, including the Department of Homeland Security's (DHS) National Infrastructure Protection Plan, calls for a partnership model that includes public and private councils to coordinate policy and information sharing and analysis centers to gather and disseminate information on threats to physical and cyber-related infrastructure. GAO was asked to determine (1) private sector stakeholders' expectations for cyber-related, public-private partnerships and to what extent these expectations are being met and (2) public sector stakeholders' expectations for cyber-related, public-private partnerships and to what extent these expectations are being met. To do this, GAO conducted surveys and interviews of public and private sector officials and analyzed relevant policies and other documents."

Information Technology: FDA Needs to Fully Implement Key Management Practices to Lessen Modernization Risks

A letter report issued by the Government Accountability Office with an abstract that begins "While FDA has taken several important steps toward modernizing its IT environment, much remains to be done. FDA reported spending about $400 million for IT investments in fiscal year 2011; however, the agency currently lacks a comprehensive IT inventory that identifies and provides key information about the systems it uses and is developing. Office of Management and Budget (OMB) and GAO guidance call for federal agencies to maintain such an inventory in order to monitor and manage their IT investments. This inventory should include information on each system, such as costs, functionality or purpose, and status. However, FDA does not have such a comprehensive list of its systems. Instead, the agency points to budget documents required by OMB, which included information on 44 IT investments for fiscal year 2011. The agency also provided a partial list of 21 mission-critical systems and modernization initiatives. Nonetheless, agency officials acknowledged that these documents do not identify all FDA’s systems or the complete costs, purpose, or status of each system. Until the agency has a complete and comprehensive inventory, it will lack critical information needed to effectively assess its IT …

A letter report issued by the Government Accountability Office with an abstract that begins "Since fiscal year 1995, the John F. Kennedy Center for the Performing Arts (Center) has been responsible and received federal funding for implementing capital improvement projects and operations and maintenance activities. The Kennedy Center's Comprehensive Building Plan identifies capital projects needed to renovate the Center and bring it into compliance with current life safety and accessibility codes. The Kennedy Center currently is planning to construct, with private funds, two new buildings to open in 2013 on a new plaza to be built adjacent to the existing facility. The Kennedy Center expects federal funding to operate and maintain these buildings. GAO was asked to examine (1) how much the Center has received in federal appropriations for capital projects, (2) the status of the Comprehensive Building Plan and updates, and (3) the potential impact of the Center's plaza project on the need for future operations and maintenance funding."

Business Systems Modernization: DOD Continues to Improve Institutional Approach, but Further Steps Needed

A letter report issued by the Government Accountability Office with an abstract that begins "For decades, the Department of Defense (DOD) has not been successful in repeated attempts to modernize its timeworn business systems and operations. In 1995, we first designated DOD's business systems modernization as "high risk," and we continue to designate it as such today. As our research on successful public and private sector organizations has shown, attempting a large-scale systems modernization program in a large organization such as DOD without, among other things, a well-defined enterprise architecture and the associated investment management controls for implementing it often results in systems that are duplicative, stovepiped, non-integrated, and unnecessarily costly to manage, maintain, and operate. In May 2001, we made recommendations to the Secretary of Defense that provided the means for effectively developing and implementing an enterprise architecture and limiting systems investments until the department had a well-defined architecture and a corporate approach to investment control and decision making. In July 2001, the department initiated a business management modernization program to, among other things, develop a business enterprise architecture and establish the investment controls needed to effectively implement it. This effort was begun as part of the Secretary of …

Due to its unique status, its governance and accountability requirements differ from those of federal entities and nonprofits. This report responds to a congressional request that GAO review LSC board oversight of LSC's operations and whether LSC has sufficient governance and accountability. GAO's report objectives are to (1) compare LSC's framework for corporate governance and accountability to others', (2) evaluate LSC's governance practices, and (3) evaluate LSC's internal control and financial reporting practices. We reviewed the LSC Act, legislative history, relevant standards and requirements, and LSC documentation and accountability requirements and interviewed board and staff."

Medicaid Third-Party Liability: Federal Guidance Needed to Help States Address Continuing Problems

A letter report issued by the Government Accountability Office with an abstract that begins "Medicaid, jointly funded by the federal government and the states, finances health care for about 56 million low-income people at an estimated total cost of about $298 billion in fiscal year 2004. Congress intended Medicaid to be the payer of last resort: if Medicaid beneficiaries have another source of health care coverage--such as private health insurance or a health plan purchased individually or provided through an employer--that source, to the extent of its liability, should pay before Medicaid does. This concept is referred to as "third-party liability." When such coverage is used, savings accrue to the federal government and the states. Using data from the U.S. Census Bureau and the states, GAO examined (1) the extent to which Medicaid beneficiaries have private health coverage and (2) problems states face in ensuring that Medicaid is the payer of last resort, including the extent to which the Deficit Reduction Act of 2005 may help address these problems."

Federal Chief Information Officers: Opportunities Exist to Improve Role in Information Technology Management

A letter report issued by the Government Accountability Office with an abstract that begins "The federal government invests billions in information technology (IT) each year to help agencies accomplish their missions. Federal law, particularly the Clinger-Cohen Act of 1996, has defined the role of Chief Information Officer (CIO) as the focal point for IT management within agencies. Given the longstanding challenges the government faces in managing IT and the continued importance of the CIO, GAO was asked to (1) determine the current roles and responsibilities of CIOs, (2) determine what potential modifications to the Clinger-Cohen Act and related laws could be made to enhance CIOs' authority and effectiveness, and (3) identify key lessons learned by CIOs in managing IT. To do this, GAO administered a questionnaire to 30 CIOs, compared responses to legislative requirements and the results of a 2004 GAO study, interviewed current CIOs, convened a panel of former agency CIOs, and spoke with the Office of Management and Budget's (OMB) Federal CIO."

Medicare Advantage: Characteristics, Financial Risks, and Disenrollment Rates of Beneficiaries in Private Fee-for-Service Plans

A letter report issued by the Government Accountability Office with an abstract that begins "Medicare Advantage (MA) plans are an alternative to the original Medicare fee-for-service (FFS) program. Private fee-for-service (PFFS) plans--one type of MA plan--give beneficiaries an option that is more like Medicare FFS than other MA plans, with a wider choice of providers and less plan management of services and providers. PFFS enrollment increased from about 35,000 beneficiaries in June 2004 to about 2.3 million in June 2008. This report compares PFFS plans to other MA plans and Medicare FFS in three areas: (1) characteristics of beneficiaries, (2) financial risks for beneficiaries who do not contact their plans before receiving services, and (3) disenrollment rates. To do this work, GAO reviewed materials from a selected sample of nine PFFS plan sponsors, analyzed Medicare data, and interviewed officials from CMS, which administers the Medicare program, and other organizations."

Internal Revenue Service: Procedural Changes Could Enhance Tax Collections

A letter report issued by the Government Accountability Office with an abstract that begins "GAO previously testified that federal contractors abused the tax system with little consequence. While performing those audits, GAO noted that the Internal Revenue Service (IRS) records sometimes contained inaccurate or outdated tax information that prevented IRS from taking appropriate collection actions against those contractors, including submitting their tax debt to the Federal Payment Levy Program (FPLP) for collection. As a result, GAO was asked to review IRS's coding of tax debt excluded from the FPLP to determine whether (1) IRS tax records contain inaccurate status or transaction codes that exclude tax debt from the FPLP, (2) IRS's monitoring could be strengthened to ensure the accuracy of its status and transaction codes, and (3) other opportunities exist to increase the amount of tax debt included in the FPLP."

Based on questions about whether the Internal Revenue Service (IRS) is fully using data from state and local governments to reduce the tax gap, GAO was asked to analyze (1) the extent to which requiring a demonstration of federal tax compliance to qualify for a state business license has the potential to improve federal tax compliance and (2) what opportunities exist for increasing arrangements that require federal tax compliance to qualify for state business licensing. To address these objectives, GAO analyzed IRS administrative and tax data. GAO identified California as a case study. GAO interviewed IRS and state officials and contacted revenue officials in the 50 states and the District of Columbia."

Supply Chain Security: CBP Works with International Entities to Promote Global Customs Security Standards and Initiatives, but Challenges Remain

U.S. Customs and Border Protection (CBP), part of the Department of Homeland Security (DHS), oversees security of the supply chain--the flow of goods from manufacturer to retailer.
