The city's three largest employers are Augusta University, the Savannah River Site (a Department of Energy nuclear facility) and the U.S. Army Cyber Center of Excellence at Fort Gordon, which oversees training for Cyber, Signal Corps, and Electronic Warfare. Despite layoffs from several companies during the U.S. economic recession and a relatively high state unemployment rate, the Augusta community has experienced a decrease in bankruptcy filings and saw a slight decrease in the unemployment rate from late 2009 to March 2011. However, these unemployment numbers are misleading as spring brings lower unemployment rates due to the Masters Golf Tournament. While unemployment fell to a two-year low of 8.3% in April 2011, unemployment rates have since risen to 9.9% as of July 2011.
