Income Taxes

The Company files U.S. federal income tax returns and various state and local income tax returns.  With few exceptions, years prior to 2013 are no longer subject to examination; net operating losses acquired in the nTelos acquisition are open to examination from 2002 forward. The Company is not subject to any state or federal income tax audits as of September 30, 2017.

The effective tax rate has fluctuated in recent periods due to the minimal base of pre-tax earnings or losses and has been further impacted by the impact of share based compensation tax benefits which are recognized as incurred under the provisions of ASC 740, "Income Taxes".
