This report was submitted to the Comptroller General in accordance with Section 5 of the Government Accountability Office Act of 2008. The report summarizes the activities of the Office of Inspector General (OIG) for the first reporting period of fiscal year 2016. During this reporting period, OIG issued two audit reports, continued fieldwork on one audit and started fieldwork on two additional audits. We also closed 2 investigations and opened 2 new investigations. In addition, we processed 144 hotline complaints, which generally did not involve GAO's programs and operations. We issued our Strategic Plan for Fiscal Years 2016-2020, which identifies the vision, goals, objectives, and strategies for our activities, under the authority of the GAO Act of 2008, to promote efficiency, effectiveness, and integrity in GAO programs and operations. We remained active in the GAO and OIG communities by briefing new GAO employees on our audit and investigative missions and by participating on Council of Inspectors General on Integrity and Efficiency committees and working groups. Details of these activities and other OIG accomplishments are provided in our report.
