In addition, the commitments under Telenet’s then existing revolving credit facility (Telenet Facility S) were reduced from €158.0 million ($217.6 million) to €35.4 million ($48.8 million) and Telenet entered into a new €286.0 million ($393.9 million) revolving facility (Telenet Facility X) that matures on September 30, 2020 and bears interest at EURIBOR plus 2.75%. Telenet Facility X has a commitment fee on unused and uncancelled balances of 1.10% per year.

VM Facility D and VM Facility E bear interest at LIBOR plus 3.25% and LIBOR plus 3.5%, respectively, in each case subject to a LIBOR floor of 0.75%. In connection with these transactions, certain lenders under the existing VM Facility C will effectively roll £500.4 million ($834.7 million) of their drawn commitments under VM Facility C to VM Facility D and VM Facility E. VM Facility D and VM Facility E are expected to be drawn on or around May 12, 2014 and, on May 22, 2014, the net proceeds, together with the net proceeds from the Additional 2029 VM Senior Secured Notes, will be used to fully redeem the 2018 VM Dollar Senior Secured Notes, including the related redemption premium.
