Singapore shares closed 0.01 percent lower on Friday, weighed by worries over the economic fallout from Italy\'s political stalemate and the likelihood of U.S. spending cuts. There is wariness about the possible extent of economic damage from automatic across-the-board spending cuts in the United States. The International Monetary Fund said on Thursday it would likely cut its 2013 growth forecasts for the United States by at least 0. 5 percentage point if the cuts are fully implemented. The IMF now projects that the U.S. economy will grow 2 percent this year. Chinese manufacturing data was the main data point on Friday, with the official purchasing managers\' index coming out at 50.1, compared with 50.4 in January, below economists\' expectations of a rise to 50.5. A reading above 50 indicates an expansion in manufacturing activity.
