Income Taxes

Note 8 – Income Taxes

     The effective tax rates for the three- and six-month periods ended June 30, 2012 were 28.9% and 29.0%, respectively.The effective tax rates for the three- and six-month periods ended June 30, 2011 were 27.7% and 27.2%, respectively. The variance is primarily attributable to increased profitability in certain foreign jurisdictions with higher income tax rates.

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