[1] Represents activity from the Acquisition date of June 15, 2012.

[2] Our deferred tax expense and current tax expense for the year ended December 31, 2011, have been adjusted to reflect the correction of an immaterial misclassification within this table of $16.6 million.

[3] Our effective tax rates were significantly lower than the federal statutory rate of 35% primarily due to the impact of lower statutory income tax rates applicable to our foreign businesses. In addition, as part of the Acquisition, the statutory tax rates in the countries of Central Europe, ranging from 9% to 20%, in which we began doing business drove the 2012 change in the effect of foreign tax rates versus 2011 and 2010.

[4] Primarily relates to the increased statutory corporate income tax rate in Serbia from 10% to 15%, effective January 1, 2013. As a result of the impact of the rate change on differences between the book basis and tax basis of intangible and other assets purchased in the Acquisition, we increased our deferred tax liability by $38.3 million in the fourth quarter of 2012.

[5] We recorded additional tax expense in 2012 due to increases in our valuation allowance related to capital loss carryforwards and operating losses in several of our jurisdictions. See further discussion below.
