[1] The goodwill resulting from the Acquisition is primarily attributable to Central Europe's licensed brand brewing, distribution and import business, anticipated synergies and the assembled workforce. We assigned the majority of the goodwill to our Europe reporting unit with a portion allocated to the Canada reporting unit resulting from synergies. The goodwill is not deductible for tax purposes. See Note 11, "Goodwill and Intangible Assets" for further discussion.

[2] During the second quarter of 2013, we finalized purchase accounting related to the Acquisition with a resulting reduction to Europe goodwill in the first half of 2013 of $15.4 million. We assigned the majority of the goodwill resulting from the Acquisition to our Europe reporting unit with a portion allocated to the Canada reporting unit resulting from synergies. The allocation of goodwill to our Canada reporting unit was not impacted by the changes made in the first half of 2013 and is now final. See Note 3, "Acquisition of StarBev" for further discussion.
