New U.S. Healthcare Law To Result In AK Steel Recording $31 Million Non-Cash Charge In First Quarter of 2010

West Chester, OH, March 23, 2010—AK Steel (NYSE: AKS) said today that it will record a non-cash charge of approximately $31 million in the first quarter of 2010 resulting from the recently-enacted Patient Protection and Affordable Care Act (the “Act”).  The charge is due to a reduction in the value of the company’s deferred tax asset as a result of a change to the tax treatment of Medicare Part D reimbursements.  The company emphasized, however, that it expects to continue to receive Medicare Part D reimbursements even after the Act and that the first quarter charge attributable to this change is non-cash in nature.
