Income Taxes	9 Months Ended

Income Taxes [Abstract]
Income Taxes	(17) Income Taxes: The Company’s effective tax rates for the nine months ended September 30, 2011 and 2010 were 33.3% and 37.9%, respectively. The Company’s effective tax rates for the three months ended September 30, 2011 and 2010 were 12.2% and 34.1%, respectively. The fluctuations in the Company’s effective tax rates are mainly because of changes in unrecognized tax benefits. The total amount of unrecognized tax benefits as of September 30, 2011 was $83 thousand (including $8 thousand of accrued interest and penalties), the recognition of which would affect the annual effective tax rate. The change in the Company’s unrecognized tax benefits from the December 31, 2010 balance of $2.0 million is due primarily to a lapsing of the statute of limitations.
