The effective tax rates of 44.1% and 99.2%, respectively, for the three and six months ended June 30, 2011 were determined using an estimated annual effective tax rate and after considering any discrete items for such periods. Due to a valuation allowance against our U.S. deferred tax assets, the effective tax rate for the three and six months ended June 30, 2011 does not include the benefit of the current year forecasted U.S. tax loss. Income tax expense for the three and six months ended June 30, 2011 is primarily due to income tax expense in foreign jurisdictions.

The effective tax rates of 149.7% and 96.5%, respectively, for the three and six months ended June 30, 2010 were determined using an estimated annual effective tax rate and after considering any discrete items for such periods.  The effective tax rate for the three and six months ended June 30, 2010 includes the impact of a valuation allowance against certain U.S. state deferred tax assets.

In 2010, we established a valuation allowance of $149,583 against the U.S. deferred tax assets that, in the judgment of management, are more likely than not to expire before they can be utilized. In assessing the recoverability of our deferred tax assets, we analyzed all evidence, both positive and negative. We considered, among other things, our deferred tax liabilities, our historical earnings and losses, projections of future income, and tax-planning strategies available to us. We have not changed our assessment regarding the recoverability of our U.S. deferred tax assets for the three and six months ended June 30, 2011.
