Three companies have placed binding binds for Polish mobile operator Polkomtel SA, the chief executive of Polkomtel shareholder KGHM Polska Miedz SA (KGH.WA) is quoted as saying by state news agency PAP Wednesday.

KGHM Chief Executive Herbert Wirth didn't say which companies had made the bids. But people familiar with the matter Friday said a consortium of Norway's Telenor ASA (TEL.OS) and Bain, as well as private equity firm Apax were expected to have placed binding bids for Polkomtel by Friday's deadline, expected at around $6.7 billion. Polish businessman Zygmunt Solorz-Zak also placed an offer, the people added.

A spokeswoman for Swedish operator TeliaSonera AB (TLSN.SK), which had earlier indicated its interest in Polkomtel, told Dow Jones Newswires the company wouldn't place a binding bid for the Polish company.

Polkomtel was put up for sale last year by its five owners.

The sale process, launched in January, has been complex because of Polkomtel's ownership structure and the Polish government's control over most shareholders.

Polkomtel's owners include oil refiner PKN Orlen SA (PKN.WA) and copper miner KGHM Polska Miedz SA (KGH.WA), each with 24.39%, as well as Poland's largest power group PGE Polska Grupa Energetyczna SA (PGE.WA), which holds a 21.85% stake. The Polish Treasury holds stakes in the three owners of 27.52%, 31.79% and 69.29% respectively.

The remaining shareholders in Polkomtel are U.K.-based telecom operator Vodafone Group PLC (VOD), which has a 24.39% stake, and Polish coal miner Weglokoks SA, which is wholly owned by the Polish Treasury and holds a 4.98% stake.
