Revenue received directly from TW represented approximately 11.8% and 5.3% of the Company’s consolidated revenue for the three months ended March 31, 2012 and 2013, respectively. Additionally, other unrelated telecommunications providers also pay the Company access revenue for terminating calls through the Company to TW customers representing 4.4% and less than 1.0% of the Company’s consolidated revenue for the three months ended March 31, 2012 and 2013, respectively. This contract expired as of December 31, 2012 and all connections were moved to TW’s facilities by January 31, 2013.

Revenues for interstate access services are based on reimbursement of costs and an allowed rate of return.  Revenues of this nature are received from the National Exchange Carrier Association in the form of monthly settlements.  Such revenues amounted to 9.4% and 11.4% of the Company’s total revenues for the three months ended March 31, 2012 and 2013, respectively.
