(NASDAQ: TWTC) today announced the pricing of its underwritten public offering of 2.375% Convertible Senior Debentures due 2026, and announced an increase in the aggregate principal amount of debentures to be sold to $325 million. The sale of the debentures is expected to close on March 29, 2006. The debentures are convertible at any time on or before March 31, 2026 into Time Warner Telecom Class A common stock, cash, or a combination of cash and Class A common stock, at the option of Time Warner Telecom, at a conversion rate of 53.6466 shares of Class A common stock per $1,000 principal amount of debentures.
Time Warner Telecom may redeem all or a portion of the debentures for cash at any time on or after April 6, 2013 at a redemption price equal to the principal amount of the debentures to be redeemed plus accrued and unpaid interest, if any, to the redemption date. Holders may require Time Warner Telecom to repurchase their debentures on April 1, 2013, April 1, 2016 or April 1, 2021 or upon the occurrence of a designated event at a repurchase price equal to the principal amount of the debentures to be repurchased plus accrued and unpaid interest, if any, to the repurchase date.
