Income Taxes [Abstract]
Income Tax Disclosure [Text Block]	5. INCOME TAXES: During the three months ended March 31, 2012, the Company recorded an income tax provision of $45.5 million, or 35.1% of income before income tax provision. This compares to an income tax provision of $44.0 million, or 39.0% of income before income tax provision for the three months ended March 31, 2011. The Company's effective tax rate for the quarter ended March 31, 2012 decreased as compared to the quarter ended March 31, 2011 primarily due to the impact of Pennsylvania state income taxes.

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.
