Although natural disasters have been much in the news, in 2010 insured catastrophe losses in the United States totaled $13.6 billion, much lower than the 2000 to 2009 average loss of $25.8 billion (in 2010 dollars). Terrorism is a new consideration. In 2003 the proportion of businesses buying terrorism coverage was 27 percent, growing to 61 percent in 2009. Until Hurricane Katrina in 2005, when insurers paid claims totaling more than $40 billion, 9/11 was the largest loss in the global history of insurance. The industry weathered the financial crisis that began in 2008, but companies began to improve their Enterprise Risk Management strategies. Most notably, AIG suffered a liquidity crisis that caused the federal government to step in to help it meet its obligations.
