    The Company fulfilled a contract with TW for the provision of wholesale network connections to TW customers in Maine and New Hampshire.  Revenue received directly from TW represented approximately 11.7% and 12.5% of the Company’s consolidated revenue for the years ended December 31, 2011 and 2012, respectively.   Additionally, other unrelated telecommunications providers also pay the Company access revenue for terminating calls through the Company to TW customers representing approximately 3% to 4% of the Company’s consolidated revenue for the years ended December 31, 2011 & 2012.    This contract expired as of December 31, 2012.  The Company negotiated a transition period during which customers 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 NECA in the form of monthly settlements.   Such revenues amounted to 9.9%, 10.1%, and 9.8% of the Company’s total revenues from continuing operations for the years ended December 31, 2010, 2011 and 2012, respectively.
