Income Taxes [Abstract]
Income Taxes	Note 3: Income Taxes The tax provision for interim periods is determined using the estimated annual effective consolidated tax rate, based on the current estimate of full-year earnings before taxes, adjusted for the impact of discrete quarterly items. For the three and six months ended June 30, 2012, our effective tax rate was 32.7% and 28.4% respectively, compared with 22.5% and 23.7% for the same periods in 2011. The increase in the effective tax rate for both periods presented primarily reflects changes in our geographic mix of earnings and the nondeductibility of the purchase premium paid related to the extinguishment of our convertible debt. In addition, during the first quarter of 2012, we recorded a discrete tax charge of $0.3 million due to the reduction of deferred tax assets associated with the legal restructuring of the ownership of our Puerto Rico operations. During the six months ended June 30, 2011, we recorded a discrete tax charge of $0.2 million, resulting from the impact of changes in tax laws in certain foreign tax jurisdictions on our deferred tax balances. Because we are a global organization, we and our subsidiaries file income tax returns in the U.S. federal jurisdiction and various state and foreign jurisdictions. During 2011, the statute of limitations for the 2007 U.S. federal tax year lapsed, leaving tax years 2008 through 2011 open to examination. For U.S. state and local jurisdictions, tax years 2007 through 2011 are open to examination. We are also subject to examination in various foreign jurisdictions for tax years 2005 through 2011. It is reasonably possible that, due to the expiration of statutes and the closing of tax audits, the liability for unrecognized tax benefits may be reduced by approximately $0.3 million during the next twelve months, which would favorably impact our effective tax rate. Accrued interest and penalties related to unrecognized tax benefits was $0.5 million and $0.4 million at June 30, 2012 and December 31, 2011, respectively.

Note 3: Income Taxes

The tax provision for interim periods is determined using the estimated annual effective consolidated tax rate, based on the current estimate of full-year earnings before taxes, adjusted for the impact of discrete quarterly items. For the three and six months ended June 30, 2012, our effective tax rate was 32.7% and 28.4% respectively, compared with 22.5% and 23.7% for the same periods in 2011. The increase in the effective tax rate for both periods presented primarily reflects changes in our geographic mix of earnings and the nondeductibility of the purchase premium paid related to the extinguishment of our convertible debt. In addition, during the first quarter of 2012, we recorded a discrete tax charge of $0.3 million due to the reduction of deferred tax assets associated with the legal restructuring of the ownership of our Puerto Rico operations. During the six months ended June 30, 2011, we recorded a discrete tax charge of $0.2 million, resulting from the impact of changes in tax laws in certain foreign tax jurisdictions on our deferred tax balances.

Because we are a global organization, we and our subsidiaries file income tax returns in the U.S. federal jurisdiction and various state and foreign jurisdictions. During 2011, the statute of limitations for the 2007 U.S. federal tax year lapsed, leaving tax years 2008 through 2011 open to examination. For U.S. state and local jurisdictions, tax years 2007 through 2011 are open to examination. We are also subject to examination in various foreign jurisdictions for tax years 2005 through 2011.

It is reasonably possible that, due to the expiration of statutes and the closing of tax audits, the liability for unrecognized tax benefits may be reduced by approximately $0.3 million during the next twelve months, which would favorably impact our effective tax rate. Accrued interest and penalties related to unrecognized tax benefits was $0.5 million and $0.4 million at June 30, 2012 and December 31, 2011, respectively.
