U.S. Agrees to Rescue Struggling Citigroup

"In addition to the [$20 billion in] capital, Citigroup will have an extremely unusual arrangement in which the government agrees to backstop a roughly $300 billion pool of its assets, containing mortgage-backed securities among other things. Citigroup must absorb the first $37 billion to $40 billion in losses from these assets. If losses extend beyond that level, Treasury will absorb the next $5 billion in losses, followed by the FDIC taking on the next $10 billion in losses. Any losses on these assets beyond that level would be taken by the Fed."
