Cablecom, the Swiss cable company, looks set to be valued at up to Sfr3.5bn (€2.3bn) after unveiling the price range for its flotation today. The issue, Switzerland's largest this year, could result in a windfall of nearly Sfr2.5bn for its private equity backers and several investment banks.

The company is backed by Apollo Management, Goldman Sachs Capital Partners and Tower Brook Capital Partners, which own 53%.
