AMSTERDAM -(Dow Jones)- Dutch cable network provider Ziggo said Thursday that it is proposing amendments to senior credit facilities. Among the amendments are some related to structural changes, including events that constitute a change of control and increased flexibility in respect of prepayments. Ziggo, one of two Dutch cable network providers, is owned by private equity firms Warburg Pincus and Cinven and could float or being sold any time soon. According to information obtained by Dow Jones Newswires Wednesday Ziggo has hired Morgan Stanley (MS), J.P. Morgan Chase & Co. (JPM), Deutsche Bank (DB) and UBS (UBS) to handle its initial public offering. An IPO could value the company at up to EUR7 billion, one person said. Swedish private equity firm EQT was planning to list its cable company Kabel Baden-Wuerttemberg GmbH & Co. KG -- a rival to Kabel Deutschland. It eventually sold it to U.S. cable operator Liberty Global Inc. (LBTYA, LBTYB) two weeks ago for EUR3.16 billion. According to a report of Financial Times Liberty Global is also interested in Ziggo. Still, as Liberty Global owns already the other Dutch cable network provider UPC, such a deal could face cartel hurdles. --By Archibald Preuschat, Dow Jones Newswires; +31 20 5715 218; archibald.preuschat@dowjones.com
