Methodology
In addition to the in-house categories, national awards were also presented for tax and transfer pricing to firms in these 27 jurisdictions or regions:
Austria, Baltic States (Estonia, Latvia, Lithuania), Belgium, Central and Eastern Europe (Bulgaria, Czech Republic, Romania, Slovenia and Slovak Republic), Cyprus, Denmark, Finland, France, Germany, Greece, Hungary, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Russia, South Africa, Spain, Sweden, Switzerland, Turkey, UK and Ukraine.
To decide the winners, International Tax Review’s team of journalists undertook detailed research from a variety of sources.
Submissions from firms were a vital part of this research. To compile the shortlists and choose the winners, the magazine’s editorial staff also consulted a large number of tax executives, tax advisers and lawyers to gain their perspective on the ground-breaking work that firms advised on in the January 1 2012 to December 31 2012 period.
The awards were judged according to:
• Size (Not conclusive, though it does indicate what a tax team is capable of taking on)
• Innovation (Did the solution the adviser employ show something more than the straightforward answer that is commonly used?)
• Complexity (Did the matter address tax issues that were out of the ordinary? What ingenuity did the adviser show to solve them?)
