Mar. 31 - Wall Street put the finishing touches on a bearish quarter for the stock market as the Treasury announced plans for sweeping changes to the financial system. Treasury Secretary Henry Paulson unveiled the recommendations, which he said were a result of a long much-needed process, but not a result of recent market chaos. Although none of the changes in the so-called "blueprint" are to be implement until the market turmoil calms, Paulson said. Shares of Merck and Schering were punished by a recommendation from a medical panel. SPEAKER: U.S. Treasury Secretary Henry Paulson Conway Gittens reports from New York.
