Note 8 – Income Taxes

 

             The effective tax rates for the three-month and six-month periods ended June 30, 2011 were 27.7% and 27.2%, respectively.  The effective tax rates for the three-month and six-month periods ended June 30, 2010 reflected benefits of 38.1% and 37.0%, respectively.  The variance primarily reflects the increased benefit derived from the effect of lower tax rates in certain foreign jurisdictions. 

 

            We believe our recorded assets and liabilities are reasonable. However, because tax laws and regulations are subject to interpretation and tax litigation is inherently uncertain, our assessments can involve a series of complex judgments about future events and rely heavily on estimates and assumptions.
