The SDPO was held by private investors and accrued interest at 11%. The settlement of the SDPO was not required by our agreement with the Seller.

[6] The goodwill resulting from the Acquisition is primarily attributable to MCCE's licensed brand brewing, distribution and import business, anticipated synergies and the assembled workforce. All of the goodwill was preliminarily assigned to the new Central Europe segment and is not expected to be deductible for tax purposes.
