Nov. 24 (Bloomberg) -- Citigroup Inc., facing the threat of a breakup or sale, received $306 billion of U.S. government guarantees for troubled mortgages and toxic assets to stabilize the bank after its stock fell 60 percent last week. Citigroup also will get a $20 billion cash injection from the Treasury Department, adding to the $25 billion the company received last month under the Troubled Asset Relief Program. In return for the cash and guarantees, the government will get $27 billion of preferred shares paying an 8 percent dividend. Citigroup rose as much as 41 percent in German trading today. The Treasury, Federal Reserve and Federal Deposit Insurance Corp. said in a joint statement that the move aims to bolster financial-market stability and help restore economic growth. The decision came after New York-based Citigroup’s tumbling share price sparked concern that depositors might pull their money and destabilize the company, which has $2 trillion of assets and operations in more than 100 countries. “It really was a must-do thing,” said Nader Naeimi, a Sydney-based strategist at AMP Capital Investors, which manages about $85 billion. “If they’d let Citigroup go, that would’ve been disastrous.” Citigroup’s stock plunged 83 percent this year and dropped below $5 last week for the first time since 1995. The shares were up $1.52 at $5.29 in Germany in recent trading. Dividend Cut “It’s a relief to see the government is committed to tackling one problem at a time,” said Ko Seoung Pil, who helps oversee almost $1 billion at HI Asset Management Co. in Seoul. The bank, which two years ago was the biggest by market value, has slipped to No. 5 after racking up four straight quarterly losses totaling $20 billion amid the worst financial crisis since the Great Depression. Citigroup shares have declined at an annual rate of more than 5 percent, including reinvested dividends, since Sanford “Sandy” Weill formed the company in 1998 through the merger of Citicorp and Travelers Group Inc. The government’s preferred shares come with warrants to buy 254 million Citigroup shares at $10.61 each, allowing taxpayers to profit if the stock rallies following the government’s investment, according to a term sheet that accompanied the agencies’ statement. Citigroup is required to pay a quarterly dividend of no more than 1 cent a share for the next three years, down from 16 cents in the most recent quarter. Capital Ratios “With these transactions, the U.S. government is taking the actions necessary to strengthen the financial system and protect U.S. taxpayers,” the agencies said. Citigroup Chief Executive Officer Vikram S. Pandit said the agreement addresses “market confidence and the recent decline in Citi’s stock,” and also strengthens the bank’s “capital ratios.” The company said its so-called Tier 1 capital ratio exceeds 9 percent with the support from the government. Terms of the asset guarantees mean Citigroup will cover the first $29 billion of pretax losses from the $306 billion pool, in addition to any reserves it already has set aside. After that, the government covers 90 percent of the losses, with Citigroup covering the other 10 percent from assets, including residential and commercial mortgages, leveraged loans and so-called structured investment vehicles. Unlike the bailouts of insurer American International Group Inc. and mortgage companies Fannie Mae and Freddie Mac, no management changes were required and Pandit gets to keep his job, government officials said. The agreement does call for the government approving executive compensation. Pandit’s Job Pandit, 51, a former Morgan Stanley banker, joined Citigroup last year as head of hedge funds and private equity and he was then picked to succeed Charles O. “Chuck” Prince after the bank’s expansion in subprime mortgages and asset-backed lending backfired. Pandit announced a plan last week to eliminate 52,000 jobs and cut costs by about $2 billion per quarter. He and three top deputies bought 1.3 million shares in a show of confidence, and Prince Alwaleed bin Talal, one of the bank’s biggest investors, said he would boost his stake to about 5 percent from 4 percent. Citigroup also issued a statement last week saying the company had “a very strong capital and liquidity position and a unique global franchise,” and Pandit held two conference calls with employees to reassure them. The stock kept plunging, forcing the bank’s board to hold an emergency meeting on Nov. 21 and thrusting executives into a weekend of discussions with the Fed and Treasury. The slump in the stock was reminiscent of what happened to Bear Stearns Cos. in March before it was sold to JPMorgan Chase & Co. and to Lehman Brothers Holdings Inc. before it went bankrupt in September. Emerging Markets The added capital and the asset guarantees are intended to provide confidence to investors that Citigroup has a big enough loss cushion to absorb bad loans as unemployment climbs and the economy sours. Citigroup remains vulnerable to losses on loans and securities outside the U.S., said Peter Kovalski, a portfolio manager at Alpine Woods Capital Investors LLC in Purchase, New York, which oversees $8 billion and holds Citigroup shares.The government plan “gives them a little bit of breathing room, but longer term, things may deteriorate and losses increase,” said Kovalski. “The Achilles heel with Citi is their exposure to emerging markets and what’s going to happen when emerging markets turn down, as they’re doing now.”
