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 9.8% and 9.5% of the Company’s total revenues for the six months ended June 30, 2010 and 2011, respectively.

The Company has a contract through 2012 with Time Warner Cable (“TW”) for the provision of wholesale network connections to TW’s customers in Maine and New Hampshire. TW represented approximately 10.3% and 11.6% of the Company’s consolidated revenue for the six months ended June 30, 2010 and 2011, respectively.  Other unrelated telecommunications providers also pay the Company access revenue for terminating calls through us to TW’s customers.
