Timeline: Ex-Credit Suisse traders charged
(Reuters) - U.S. authorities have accused a group of former Credit Suisse Group AG (CSGN.VX) traders of falsely inflating the value of mortgage-backed securities on the investment bank's books as the financial crisis began to take shape.
The traders were able to artificially manipulate pricing on a mortgage-backed bond portfolio for six months, from August 2007 through February 2008, despite clear signs that the value of those securities had deteriorated significantly, according to criminal charges filed by the Justice Department and a civil lawsuit from the Securities and Exchange.
Their actions contributed to Credit Suisse taking an unexpected writedown of $2.65 billion on subprime mortgage trades.
Here is a timeline of key events in the subprime mortgage market around the time of the alleged pricing manipulation at Credit Suisse:
December, 2006 - Ownit Mortgage Solutions files for bankruptcy protection.
Feb 27, 2007 - Freddie Mac announces it will no longer buy the most risky subprime mortgages.
