Income Taxes

The Company or one of its subsidiaries files income tax returns in the U.S. federal jurisdiction, various states and Canada. With a few exceptions, the Company is no longer subject to U.S. federal, state and local, or Canadian examinations by tax authorities for years before 2005.

For the three months ended June 30, 2011 and 2010, the effective income tax rates varied from the statutory federal income tax rate of 35.0%, primarily as a result of the effect of state income taxes, net of the federal benefit and permanent differences between book and tax net income.
