Princeton, New Jersey-based telecom, cable and internet services outfit RCN Corp, one of the three independent companies spun out from C-Tec Corp earlier this year (CI No 3,103), has raised $575m in proceeds from a private offering of two tranches of debt securities. The offering consisted of 10% senior notes and 11.125% senior discount notes, both due in 2007. The bulk of the proceeds will be used for the development and expansion of RCN’s fiber optic network.
