About half of the expected work force reductions will come from business sales; Citigroup already announced that it was selling Citi Global Services and its German retail banking business, accounting for about 18,000 jobs. Citi is planning to sell other businesses, too, but has not announced them yet, a spokesman said.
The other half of the work force reductions will come from layoffs and attrition, the spokesman said.
The New York-based bank has posted four straight quarterly losses, including a loss of $2.8 billion during the third quarter.
In an effort to instill confidence in the company, Citigroup emphasized in its presentation Monday that its Tier 1 capital ratio, a measure of financial strength, is 10.4 percent after a $25 billion investment from the government -- part of the $700 billion financial rescue package passed by Congress last month. That ratio is higher than peers Bank of America Corp. and Wells Fargo & Co., after their purchases of Merrill Lynch and Wachovia Corp., respectively.
Citigroup also stressed that it has doubled reserves in a year to $24 billion; that its revenues are stable; and that Citigroup has lower exposure to U.S. consumer mortgages than JPMorgan Chase & Co., Bank of America and Wells Fargo.
But the announcements were not met with enthusiasm from investors. Citi shares fell 46 cents, or 4.8 percent, to $9.06 in morning trading. The company's shares have been trading at 13-year lows.
Shortly before the town hall meeting in New York, Citigroup Chairman Win Bischoff said at a business forum in Dubai, United Arab Emirates, that it would be irresponsible for Citi and other companies not to look at staffing in the event of a prolonged economic downturn.
"What all of us have done -- and perhaps injudiciously -- we've added a lot of people over ... this very benign period," Bischoff said.
"If there is a reversion to the mean ... those job losses will obviously fall particularly heavily on the financial sector," he added. "Certainly they will fall particularly heavily on London and New York."
A Citigroup spokesman said that while certain regions and businesses might have higher concentrations of job cuts, they would generally be across the entire company and around the world.
In his comments to The Associated Press, Bischoff did not rule out the likelihood that Citi's leaders would go without bonuses this year -- a move that would effectively amount to a substantial pay cut for the company's executives.
"Watch this space," he said when asked about lost bonuses.
On Sunday, Goldman Sachs Group Inc. said seven top executives, including Chief Executive Lloyd Blankfein, opted out of receiving cash or stock bonuses for 2008 amid the ongoing credit crisis.
