The companies finalised the deal in September 2011 following positive opinion of Office of Competition and Consumer Protection (UOKiK).

The Office of Competition and Consumer Protection (UOKiK) was established in 1990 as the Antimonopoly Office.

Right now the Office works under the name Office of Competition and Consumer Protection and bases its activities on the newly enacted Act on the Protection of Competition and Consumers from 2007.

For example, on January 4, 2007, the Polish Office of Competition and Consumer Protection fined twenty banks a total of PLN 164 million (about $56 million) for jointly setting MasterCard's and Visa's interchange fees.
