A letter report issued by the Government Accountability Office with an abstract that begins "To enhance aviation security, the Department of Homeland Security's (DHS) Transportation Security Administration (TSA) developed a program--known as Secure Flight--to assume from air carriers the function of matching passenger information against terrorist watch-list records. In accordance with a mandate in the Department of Homeland Security Appropriations Act, 2008, GAO's objective was to assess the extent to which TSA met the requirements of 10 statutory conditions related to the development of the Secure Flight program. GAO is required to review the program until all 10 conditions are met. In September 2008, DHS certified that it had satisfied all 10 conditions. To address this objective, GAO (1) identified key activities related to each of the 10 conditions; (2) identified federal guidance and best practices that are relevant to successfully meeting each condition; (3) analyzed whether TSA had demonstrated, through program documentation and oral explanation, that the guidance was followed and best practices were met; and (4) assessed the risks associated with not fully following applicable guidance and meeting best practices."

A letter report issued by the Government Accountability Office with an abstract that begins "Cost growth is a prevalent problem in Navy shipbuilding programs, particularly for the first ships in new classes. In response to a mandate in the conference report accompanying the Defense Appropriations Act for Fiscal Year 2008, GAO undertook this review to (1) identify key practices employed by leading commercial ship buyers and shipbuilders that ensure satisfactory cost, schedule, and ship performance; (2) determine the extent to which Navy shipbuilding programs employ these practices; and (3) evaluate how commercial and Navy business environments incentivize the use of best practices. To address these objectives, GAO visited leading commercial ship buyers and shipbuilders, reviewed its prior Navy work, and convened a panel of shipbuilding experts."

A letter report issued by the Government Accountability Office with an abstract that begins "The Joint Committee on Taxation identified improved taxpayer compliance with the real-estate tax deduction as a way to reduce the federal tax gap--the difference between taxes owed and taxes voluntarily and timely paid. Regarding the deduction, GAO was asked to examine (1) factors that contribute to taxpayers including nondeductible charges, (2) the extent that taxpayers may be claiming such charges, (3) the extent that Internal Revenue Service (IRS) examinations focus on the inclusion of such charges, and (4) possible options for improving taxpayer compliance. GAO surveyed a generalizable sample of local governments, studied taxpayer compliance in two jurisdictions that met selection criteria, reviewed IRS documents, and interviewed government officials and others. Addressing the complexity of current tax law on real-estate tax deductions was outside the scope of this review."
