Business Concentrations [Abstract]
Business Concentrations	Business Concentrations Geographic As of December 31, 2014, approximately 85% of the Company's access line equivalents were located in Maine, New Hampshire and Vermont. As a result of this geographic concentration, the Company's financial results will depend significantly upon economic conditions in these markets. A deterioration or recession in any of these markets could result in a decrease in demand for the Company's services and a resulting loss of access line equivalents which could have a material adverse effect on the Company's business, financial condition, results of operations, liquidity and/or the market price of the Company's outstanding securities. In addition, if state regulators in Maine, New Hampshire or Vermont were to take an action that is adverse to the Company's operations in those states, the Company could suffer greater harm from that action by state regulators than it would from action in other states because of the concentration of operations in those states. Labor As of December 31, 2014, we employed a total of 3,052 employees, 1,914, or 63%, of whom were covered by 13 collective bargaining agreements. As of December 31, 2014, approximately 1,700 employees were covered by two collective bargaining agreements that expired during 2014. See note (10) "Employee Benefit Plans" and note (18) "Commitments and Contingencies" for additional information.
