 On April 18, 2011, U.S.-based rating agency S&P issued a "negative" outlook on the U.S.'s "AAA" (highest quality) sovereign-debt rating for the first time since the rating agency began in 1860, indicating there was a one-in-three chance of an outright reduction in the rating over the next two years.S&P considered the government budget deficit of more than 11 percent of gross domestic product (GDP), and net government debt rising to about 80 percent or more of GDP by 2013, to be high relative to other "AAA" countries.According to S&P, meaningful progress towards balancing the budget would be required to move the U.S. back to a "stable" outlook.
