Parties interested in taking a stake in the Warsaw Stock Exchange have been able to examine the company's books since the beginning of this week, a person familiar with the matter told Dow Jones Newswires.

The four consortia selected by the Polish government will have until Sept. 25 to present a binding offer, the person said. The consortia are led by London Stock Exchange Group PLC (LSE.LN), Deutsche Boerse AG (DB1.XE), NYSE Euronext (NYX) and Nasdaq OMX Group Inc. (NDAQ).

Warsaw Stock Exchange is hoping for a quick privatization, management board chairman Ludwik Solewski told Dow Jones Newswires. "There is a chance that it will be completed by the end of the year," he said.

The Polish government, which owns almost all of the shares in the Warsaw exchange, wants to sell up to 73.8% of the shares in the bourse, which has Eastern Europe's highest trading volume.

A Deutsche Boerse spokesman declined to comment, citing a confidentiality agreement. The London Stock Exchange and Euronext also declined to comment.
