Income Taxes [Abstract]

Income Taxes

Note 8 – Income Taxes

     The effective tax rate for the three-month period ended March 31, 2012 was 29.1% as compared to 26.4% for the three-month period ended March 31, 2011. 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.
