For the first six months of 2011, the Company recorded an income tax provision of $11.3 million, or 38.2%, compared to $2.9 million, or 37.0%, for the first six months of 2010. The increase in the 2011 tax provision is primarily due to changes in certain state tax laws that disallows deductions for prior year’s net operating losses.
