Income Taxes [Abstract]
Income Taxes	Note L – Income Taxes The Company recorded income tax expense of $3.5 million and $2.7 million during the first quarters of 2012 and 2011, respectively. The Company's first quarter 2012 effective tax rate of 24.6% is lower than its domestic federal statutory rate primarily due to a one-time foreign tax benefit of $1.0 million and a reduction of a foreign tax valuation allowance. The total unrecognized tax benefits excluding interest and penalties were $10.6 million at both February 29, 2012 and November 30, 2011. The total amount of penalties and interest recognized in the statement of financial position were $0.7 million and $0.4 million as of February 29, 2012 and November 30, 2011, respectively. Interest and penalties related to unrecognized tax benefits are recorded as a component of income tax expense. During the first quarter of 2012, the Company recognized $0.3 million of interest and penalty expense. During the next twelve months, due to the expiration of open statutes of limitations, the Company's unrecognized tax benefits, excluding interest and penalties, would decrease by $4.3 million. Of the $4.3 million unrecognized tax benefit that is reasonably expected to decrease during the next twelve months, $1.4 million would, if recognized, impact the Company's effective rate. It is also possible that additional unrecognized tax benefits could arise during the next twelve months that would change such estimate. As of February 29, 2012, the Company had approximately $124.8 million of domestic federal net operating loss carryforwards (NOLCs), $109.1 million of state and local NOLCs, $0.8 foreign tax credit carryforwards and $0.2 million of AMT credit carryforwards. The majority of the federal, state and local NOLCs expire in the tax years 2022 through 2032 while the foreign tax credit carryforwards expire between tax years 2012 and 2021.
