OCC Statement Regarding Treasury Securities Collateral Following The S&P Rating Change On U.S. Sovereign Debt

Valuations Will Remain the Same with No Current Plans to Change Haircuts

CHICAGO (August 7, 2011) OCC said today it has no current plans to adjust its current valuations or haircuts on Treasury Securities used as collateral in light of the Standard & Poor's rating change on U.S. sovereign debt.

OCC will continue to monitor the situation, as it has done over the past few weeks, and will determine appropriate action, if necessary, should there be any disruption in the Treasury market.

OCC has a long record of solid risk management that has helped ensure the security and stability of the markets it serves, and is confident this record will continue through the current situation.
