From the NYT:
"Senior officials from the Bush administration and the Federal Reserve on Friday informed top executives of Fannie Mae and Freddie Mac, the mortgage finance giants, that the government was preparing to seize the two companies and place them in a conservatorship, officials and company executives briefed on the discussions said.
The plan, effectively a government bailout, was outlined in separate meetings that the chief executives were summoned to attend on Friday at the office of the companiesâ€™ new regulator. The executives were told that, under the plan, they and their boards would be replaced, shareholders would be virtually wiped out, but the companies would be able to continue functioning with the government generally standing behind their debt, people briefed on the discussions said.
It is not possible to calculate the cost of any government bailout, but the huge potential liabilities of the companies could cost taxpayers tens of billions of dollars and make any rescue among the largest in the nationâ€™s history."
