A letter report issued by the Government Accountability Office with an abstract that begins "In January 2007 Federal Aviation Administration (FAA) reported the results of its study that assigned the fiscal year 2005 costs of its Air Traffic Organization (ATO) to users. FAA used this study to support the President's proposal to replace many current excise taxes with cost-based fees for commercial aviation users and higher fuel taxes for general aviation users. GAO assessed (1) the consistency of FAA's cost assignment methodology with established standards and guidance, (2) the support for selected cost assignment assumptions and methods, and (3) the impact of including budgeted capital costs in the cost baseline. GAO compared FAA's methodology to federal accounting standards and international guidance, reviewed available documents and analyses supporting FAA's assumptions and methods, and interviewed FAA officials and consultants."

A letter report issued by the Government Accountability Office with an abstract that begins "Since 1988, the Department of State (State) has ordered over 270 evacuations from overseas posts due to civil strife, terrorist incidents, natural disasters, conventional war threats, and disease outbreaks. To prepare for evacuation, overseas posts rely on a variety of guidance, plans, and training, such as Emergency Action Plans (EAP). GAO was asked to assess State's (1) guidance and plans to prepare for evacuation, (2) training and exercises to prepare post staff for crisis, and (3) efforts to collect, analyze, and incorporate evacuation lessons learned into guidance and training. GAO examined State and Department of Defense (DOD) documents, spoke with State and DOD officials, conducted a survey of 243 overseas posts, and completed 22 structured interviews with State personnel."

A letter report issued by the Government Accountability Office with an abstract that begins "Prices for four energy commodities--crude oil, heating oil, unleaded gasoline, and natural gas--have risen substantially since 2002. Some observers believe that higher energy prices are the result of changes in supply and demand. Others believe that increased futures trading activity has also contributed to higher prices. This report, conducted under the Comptroller General of the United States' authority, examines (1) trends and patterns in the physical and energy derivatives markets, (2) the scope of the Commodity Futures Trading Commission's (CFTC) regulatory authority over these markets, and (3) the effectiveness of CFTC's monitoring and detection of market abuses and enforcement. For this work, GAO analyzed futures and large trader data and interviewed market participants, experts, and officials at six federal agencies."
