tax payment was fully covered by its existing litigation reserves, which were boosted to $6.7 billion after the WorldCom settlement. The bank does not plan to adjust its remaining reserves and considers them adequate for its exposure to additional pending Enron and investment research-related lawsuits. Citigroup Chief Executive Charles Prince, who took over at the helm of the company in 2003, said it was a key priority for the bank to resolve major cases like this one and "to put a difficult chapter in our history behind us".

Citigroup was told by the U.S. Federal Reserve in March to delay any big takeover plans until the company tightened internal controls and addressed a slew of regulatory problems. --More 2356 Local Time 2056 GMT
