From the Wall Street Journal (sub req’d):

The federal government agreed Sunday night to rescue Citigroup Inc. by helping to absorb potentially hundreds of billions of dollars in losses on toxic assets on its balance sheet and injecting fresh capital into the troubled financial giant.

The agreement marks a new phase in government efforts to stabilize U.S. banks and securities firms. After injecting nearly $300 billion of capital into financial institutions, federal officials now appear to be willing to help shoulder bad assets, on a targeted basis, from specific institutions.  Citigroup is one of the world’s best-known banking brands, with more than 200 million customer accounts in 106 countries. Its plunging stock price threatened to spook customers and imperil the bank. If the government’s rescue plan is a success, it could help bring stability …

Under the plan, Citigroup and the government have identified a pool of about $306 billion in troubled assets. Citigroup will absorb the first $29 billion in losses in that portfolio. After that, three government agencies — the Treasury Department, the Federal Reserve and the Federal Deposit Insurance Corp. — will take on any additional losses, though Citigroup could have to share a small portion of additional losses.
