Accounting Policies [Abstract]
Principles of consolidation	Principles of consolidation: The consolidated financial statements include the accounts of all wholly owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation. The Company has no involvement with variable interest entities. The Company accounts for investments over which it has significant influence but not a controlling financial interest using the equity method of accounting.
Use of estimates	Use of estimates: Management of the Company has made a number of estimates and assumptions related to the reporting of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting periods. Management reviews its estimates, including those related to recoverability and useful lives of assets as well as liabilities for income taxes and pension benefits. Changes in facts and circumstances may result in revised estimates, and actual results could differ from those reported estimates.
Cash and cash equivalents	Cash and cash equivalents: The Company considers all temporary cash investments purchased with a maturity of three months or less to be cash equivalents. Cash equivalents at December 31, 2015 included $40.1 million invested in institutional cash management funds. The Company places its temporary cash investments with high credit quality financial institutions. Generally, such investments are in excess of FDIC or SIPC insurance limits.
Accounts receivable	Accounts receivable: Accounts receivable are recorded at the invoiced amount and generally do not bear interest. The allowance for doubtful accounts is the Company’s best estimate of the amount of probable credit losses in the Company’s existing accounts receivable. The Company determines the allowance based on historical write-off experience and industry and local economic data. The Company reviews its allowance for doubtful accounts monthly. Past due balances meeting specific criteria are reviewed individually for collectability. All other balances are reviewed on a pooled basis. Account balances are charged off against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. Accounts receivable are concentrated among customers within the Company's geographic service area and large telecommunications companies.
Inventories	Inventories: The Company's inventories consist primarily of items held for resale such as devices and accessories. The Company values its inventory at the lower of cost or market. Inventory cost is computed on an average cost basis. Market value is determined by reviewing current replacement cost, marketability and obsolescence.
Investments	Investments: The classifications of debt and equity securities are determined by management at the date individual investments are acquired. The appropriateness of such classification is periodically reassessed. The Company monitors the fair value of all investments, and based on factors such as market conditions, financial information and industry conditions, the Company will reflect impairments in values as is warranted. The classification of those securities and the related accounting policies are as follows: Investments Carried at Fair Value: Investments in equity and bond mutual funds and investment trusts held within the Company’s rabbi trust, which is related to the Company’s unfunded Supplemental Executive Retirement Plan, are reported at fair value using net asset value per share. The Company has elected to recognize unrealized gains and losses on investments carried at fair value in earnings, pursuant to the fair value option in Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) 820, Fair Value Measurement. Investments Carried at Cost: Investments in common stock in which the Company does not have a significant ownership (less than 20%) and for which there is no ready market, are carried at cost. This category includes required investments to obtain services, primarily with CoBank. Information regarding investments carried at cost is reviewed for evidence of impairment in value. Impairments are charged to earnings and a new cost basis for the investment is established. Equity Method Investments: Investments in partnerships and in unconsolidated corporations where the Company's ownership is 20% or more, but less than 50%, or where the Company otherwise has the ability to exercise significant influence, are reported under the equity method. Under this method, the Company's equity in earnings or losses of investees is reflected in earnings. Distributions received reduce the carrying value of these investments. The Company recognizes a loss when there is a decline in value of the investment which is other than a temporary decline.
Property, plant and equipment	Property, plant and equipment: Property, plant and equipment is stated at cost less accumulated depreciation and amortization. The Company capitalizes all costs associated with the purchase, deployment and installation of property, plant and equipment, including interest costs on major capital projects during the period of their construction. Expenditures, including those on leased assets, which extend the useful life or increase its utility, are capitalized. Maintenance expense is recognized when repairs are performed. Depreciation is calculated on the straight-line method over the estimated useful lives of the assets. Depreciation and amortization is not included in the income statement line items “Cost of goods and services” or “Selling, general and administrative.” Depreciable lives are assigned to assets based on their estimated useful lives. Leasehold improvements are depreciated over the lesser of their useful lives or respective lease terms. The Company takes technology changes into consideration as it assigns the estimated useful lives, and monitors the remaining useful lives of asset groups to reasonably match the remaining economic life with the useful life and makes adjustments when necessary.
Valuation of long-lived assets	Valuation of long-lived assets: Long‑lived assets, such as property, plant, and equipment, and purchased intangibles subject to amortization, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized by the amount by which the carrying amount of the asset exceeds the fair value of the asset.
Fair value	Fair value: Fair value is defined as the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Financial instruments presented on the consolidated balance sheets for which the carrying value approximates fair value include: cash and cash equivalents, receivables, investments carried at fair value, payables, accrued liabilities, interest rate swaps and variable-rate long-term debt. The Company measures its interest rate swaps at fair value and recognizes such derivative instruments as either assets or liabilities on the Company’s consolidated balance sheet. Changes in the fair value of swaps are recognized in other comprehensive income, as the Company has designated these swaps as cash flow hedges for accounting purposes. The Company entered into these swaps to manage a portion of its exposure to interest rate movements by converting a portion of its variable rate long-term debt to fixed rate debt.
Asset retirement obligations	Asset retirement obligations: The Company records the fair value of an asset retirement obligation as a liability in the period in which it incurs a legal obligation associated with the retirement of tangible long-lived assets that results from acquisition, construction, development and/or normal use of the assets. The Company also records a corresponding asset, which is depreciated over the life of the tangible long-lived asset. Subsequent to the initial measurement of the asset retirement obligation, the obligation is adjusted at the end of each period to reflect the passage of time and changes in the estimated future cash flows underlying the obligation. The Company records the retirement obligation on towers owned and cell site improvements where there is a legal obligation to remove the tower or cell site improvements and restore the site to its original condition. The terms associated with its operating leases, and applicable zoning ordinances of certain jurisdictions, define the Company’s obligations which are estimated and vary based on the size of the towers. The Company’s cost to remove the tower or cell site improvements is amortized over the life of the tower or cell site assets.
Goodwill and intangible assets	Goodwill and intangible assets: In connection with the acquisition of a business, a portion of the purchase price may be allocated to identifiable intangible assets with indefinite lives, such as franchise rights, and goodwill, which is an asset representing the future economic benefits arising from other assets acquired in a business combination that are not individually identified and separately recognized. Goodwill is recorded in the segment that was affected by the acquisition. Goodwill is not amortized but is tested for impairment on at least an annual basis. Impairment testing is required more often than annually if an event or circumstance indicates that impairment is more likely than not to have occurred. In conducting its annual impairment testing, the Company may first perform a qualitative assessment of whether it is more likely than not that a reporting unit’s fair value is less than its carrying amount. If not, no further goodwill impairment testing is required. If it is more likely than not that a reporting unit’s fair value is less than its carrying amount, or if the Company elects not to perform a qualitative assessment of a reporting unit, the Company then compares the fair value of the reporting unit to the related net book value. If the net book value of a reporting unit exceeds its fair value, an impairment loss is measured and recognized. The Company elected not to perform the qualitative assessment and performed a quantitative test comparing the fair value with the carrying amounts and concluded that no impairment existed as of October 1, 2016. Intangible assets with indefinite lives, primarily cable franchise rights, are assessed annually, at November 1, for impairment and in interim periods if certain triggering events occur indicating that the carrying value may be impaired.
Deferred charges and other assets	Deferred charges and other assets: Deferred charges and other assets consist of derivatives used for hedging purposes and debt issuance costs related to available lines of credit and other unused funds, which are amortized on a straight-line method over the remaining draw period.
Retirement plans	Retirement plans: The Company maintains a Supplemental Executive Retirement Plan (“SERP”) for selected employees. This is an unfunded defined contribution plan. The Company created and funded a rabbi trust to hold assets equal to the liabilities under this plan. Participant balances and earnings thereon continue to be maintained for this plan, but no new participants or contributions have been added to the plan since 2010. Through the Company’s acquisition of nTelos, the Company assumed nTelos’ non-contributory defined benefit pension plan (“Pension Plan”) covering all employees who met eligibility requirements and were employed by nTelos prior to October 1, 2003. The Pension Plan was closed to nTelos employees hired on or after October 1, 2003. Pension benefits vest after five years of plan service and are based on years of service and an average of the five highest consecutive years of compensation subject to certain reductions if the employee retires before reaching age 65 and elects to receive the benefit prior to age 65. Effective December 31, 2012, nTelos froze future benefit accruals. The Company uses updated mortality tables published by the Society of Actuaries that predict increasing life expectancies in the United States. IRC Sections 412 and 430 and Sections 302 and 303 of the Employee Retirement Income Security Act of 1974, as amended establish minimum funding requirements for defined benefit pension plans. The minimum required contribution is generally equal to the target normal cost plus the shortfall amortization installments for the current plan year and each of the six preceding plan years less any calculated credit balance. If plan assets (less calculated credits) are equal to or exceed the funding target, the minimum required contribution is the target normal cost reduced by the excess funding, but not below zero. The Company’s policy is to make contributions to stay at or above the threshold required in order to prevent benefit restrictions and related additional notice requirements and is intended to provide not only for benefits based on service to date, but also for those expected to be earned in the future. The Company also assumed one qualified nonpension postretirement benefit plan that provides certain health care benefits for nTelos retired employees that meet eligibility requirements. The health care plan is contributory, with participants’ contributions adjusted annually. This plan is not available to employees hired after April 1993. The accounting for the plan anticipates that the Company will maintain a consistent level of cost sharing for the benefits with the retirees. The Company’s share of the projected cost of benefits that will be paid after retirement is generally being accrued by charges to expense over the eligible employees’ service periods to the dates they are fully eligible for benefits. The Company records annual amounts relating to the Pension Plan and postretirement benefit plan based on calculations that incorporate various actuarial and other assumptions, including discount rates, mortality, assumed rates of return, turnover rates and healthcare cost trend rates. The Company reviews its assumptions on an annual basis and makes modifications to the assumptions based on current rates and trends when it is appropriate to do so. We recognize gains and losses on pension and postretirement plan assets and obligations immediately in our operating results. These gains and losses are measured annually at December 31 and accordingly are recorded during the fourth quarter, unless earlier re-measurements are required. The Company maintains a defined contribution 401(k) plan under which substantially all employees may defer a portion of their earnings on a pretax basis, up to the allowable federal maximum annual contribution amount. The Company may make matching and discretionary contributions to this plan. The Company acquired nTelos' defined contribution 401(k) plan at the time of the acquisition. The nTelos plan was merged into the Company's plan as of December 31, 2016. None of these plans directly hold Company common stock in their investment portfolios.
Income taxes	Income taxes: Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. The Company evaluates the recoverability of tax assets generated on a state-by-state basis from net operating losses apportioned to that state. Management uses a more likely than not threshold to make that determination and has concluded that at December 31, 2016 and 2015, a valuation allowance against certain state deferred tax assets is necessary, as discussed in Note 6. The Company recognizes the effect of income tax positions only if those positions are more likely than not of being sustained. Recognized income tax positions are measured at the largest amount that is greater than 50% likely of being realized. Changes in recognition or measurement are reflected in the period in which the change in judgment occurs. The Company’s policy is to record interest related to unrecognized tax benefits in interest expense and penalties in selling, general, and administrative expenses.
Revenue recognition	Revenue recognition: The Company recognizes revenue when persuasive evidence of an arrangement exists, services have been rendered or products have been delivered, the price to the buyer is fixed and determinable and collectability is reasonably assured. Revenues are recognized by the Company based on the various types of transactions generating the revenue. For services, revenue is recognized as the services are performed. For equipment sales, revenue is recognized when the sales transaction is complete. Under the Sprint Management Agreement, postpaid wireless service revenues are reported net of an 8% Management Fee and an 8.6% Net Service Fee, retained by Sprint. Prepaid wireless service revenues are reported net of a 6% Management Fee retained by Sprint. Under the Company’s amended affiliate agreement, Sprint agreed to waive the management fee, which is historically presented as a contra-revenue by the Company, for a period of approximately six years. The impact of Sprint’s waiver of the management fee over the approximate six-year period is reflected as an increase in revenue, offset by the non-cash adjustment to recognize this impact on a straight-line basis over the contract term of approximately 14 years.
Earnings per share	Earnings per share: Basic net income(loss) per share was computed on the weighted average number of shares outstanding. Diluted net income per share was computed under the treasury stock method, assuming the conversion as of the beginning of the period, for all dilutive stock options. There were no adjustments to net income in the computation of diluted earnings per share for any of the years presented.
Contingencies	Contingencies: The Company is involved in various claims and legal actions arising in the ordinary course of business. In the opinion of management, the ultimate disposition of these matters will not have a material adverse effect on the Company’s consolidated financial position, results of operations, or liquidity.
Adoption of New Accounting Principles	Adoption of New Accounting Principles During 2016, the Company adopted four recent accounting principles: Accounting Standards Update 2015-3, “Interest – Imputation of Interest” (ASU 2015-3), ASU 2015-17, “Balance Sheet Classification of Deferred Taxes”, ASU 2016-9, “Improvements to Employee Share-based Payment Accounting,” and ASU 2015-16, “Simplifying the Accounting for Measurement-Period Adjustments.” ASU 2015-3 requires that premiums, discounts, and loan fees and costs associated with long term debt be reflected as a reduction of the outstanding debt balance. Previous guidance had treated such loan fees and costs as a deferred charge on the balance sheet. As a result of implementing ASU 2015-3, the Company reclassified $1.6 million of unamortized loan fees and costs included in deferred charges and other assets as of December 31, 2015 to long-term debt. Approximately $0.5 million was allocated to current maturities of long-term debt, and $1.1 million to long term debt. Total assets, as well as total liabilities and shareholders’ equity, were also reduced by the same $1.6 million. In addition, the Company reclassified $4.3 million of unamortized loan fees and costs included in deferred charges and other assets to long term debt in connection with the new Term loan A-1 and A-2 borrowing related to the acquisition of nTelos. Total assets, as well as total liabilities and shareholders’ equity, were also reduced by the same $4.3 million. There was no impact on the statements of income or cash flows. ASU 2015-17 simplifies accounting for deferred taxes by eliminating the requirement to present deferred tax assets and liabilities as current and non-current in a classified balance sheet. Due to the immaterial balance of current deferred tax assets ($0.9 million as of December 31, 2015), the Company has elected to apply this guidance prospectively, and thus prior periods have not been retrospectively adjusted. ASU 2016-9 simplifies certain provisions related to the accounting for the tax effects of stock-based compensation transactions. In particular for the Company, it eliminates the requirement to determine for each award whether the difference between book compensation and tax compensation results in an excess tax benefit or a tax deficiency, which generally speaking, result in an entry to additional paid-in-capital. Under the new guidance, all tax effects for exercised or vested awards are recognized as discrete items in income tax expense, and the Company recognized $1.7 million of tax benefits through income tax expense in 2016. The new guidance also allows an employer to withhold shares to cover more than the minimum statutory withholding taxes (but not more than the maximum statutory withholding requirements) without causing an equity-classified award to become a liability classified award. The other provisions of the new guidance are either not applicable or have no significant impact on the Company’s accounting for stock-based compensation transactions. The Company has elected to early adopt the new guidance and apply it prospectively to tax effects on share-based compensation transactions. ASU 2015-16 requires that an acquirer recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. See Note 16 for adjustments recorded during 2016.

Accounts receivable are concentrated among customers within the Company's geographic service area and large telecommunications companies.

Inventories

Inventories: The Company's inventories consist primarily of items held for resale such as devices and accessories. The Company values its inventory at the lower of cost or market. Inventory cost is computed on an average cost basis. Market value is determined by reviewing current replacement cost, marketability and obsolescence.

Investments

Investments: The classifications of debt and equity securities are determined by management at the date individual investments are acquired. The appropriateness of such classification is periodically reassessed. The Company monitors the fair value of all investments, and based on factors such as market conditions, financial information and industry conditions, the Company will reflect impairments in values as is warranted. The classification of those securities and the related accounting policies are as follows:

Investments Carried at Fair Value: Investments in equity and bond mutual funds and investment trusts held within the Company’s rabbi trust, which is related to the Company’s unfunded Supplemental Executive Retirement Plan, are reported at fair value using net asset value per share. The Company has elected to recognize unrealized gains and losses on investments carried at fair value in earnings, pursuant to the fair value option in Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) 820, Fair Value Measurement.

Investments Carried at Cost: Investments in common stock in which the Company does not have a significant ownership (less than 20%) and for which there is no ready market, are carried at cost. This category includes required investments to obtain services, primarily with CoBank. Information regarding investments carried at cost is reviewed for evidence of impairment in value. Impairments are charged to earnings and a new cost basis for the investment is established.

Equity Method Investments: Investments in partnerships and in unconsolidated corporations where the Company's ownership is 20% or more, but less than 50%, or where the Company otherwise has the ability to exercise significant influence, are reported under the equity method. Under this method, the Company's equity in earnings or losses of investees is reflected in earnings. Distributions received reduce the carrying value of these investments. The Company recognizes a loss when there is a decline in value of the investment which is other than a temporary decline.

Property, plant and equipment

Property, plant and equipment: Property, plant and equipment is stated at cost less accumulated depreciation and amortization. The Company capitalizes all costs associated with the purchase, deployment and installation of property, plant and equipment, including interest costs on major capital projects during the period of their construction. Expenditures, including those on leased assets, which extend the useful life or increase its utility, are capitalized. Maintenance expense is recognized when repairs are performed. Depreciation is calculated on the straight-line method over the estimated useful lives of the assets. Depreciation and amortization is not included in the income statement line items “Cost of goods and services” or “Selling, general and administrative.” Depreciable lives are assigned to assets based on their estimated useful lives. Leasehold improvements are depreciated over the lesser of their useful lives or respective lease terms. The Company takes technology changes into consideration as it assigns the estimated useful lives, and monitors the remaining useful lives of asset groups to reasonably match the remaining economic life with the useful life and makes adjustments when necessary.

Valuation of long-lived assets

Valuation of long-lived assets: Long‑lived assets, such as property, plant, and equipment, and purchased intangibles subject to amortization, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized by the amount by which the carrying amount of the asset exceeds the fair value of the asset.

Fair value

Fair value: Fair value is defined as the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Financial instruments presented on the consolidated balance sheets for which the carrying value approximates fair value include: cash and cash equivalents, receivables, investments carried at fair value, payables, accrued liabilities, interest rate swaps and variable-rate long-term debt.

The Company measures its interest rate swaps at fair value and recognizes such derivative instruments as either assets or liabilities on the Company’s consolidated balance sheet. Changes in the fair value of swaps are recognized in other comprehensive income, as the Company has designated these swaps as cash flow hedges for accounting purposes. The Company entered into these swaps to manage a portion of its exposure to interest rate movements by converting a portion of its variable rate long-term debt to fixed rate debt.

Asset retirement obligations

Asset retirement obligations: The Company records the fair value of an asset retirement obligation as a liability in the period in which it incurs a legal obligation associated with the retirement of tangible long-lived assets that results from acquisition, construction, development and/or normal use of the assets. The Company also records a corresponding asset, which is depreciated over the life of the tangible long-lived asset. Subsequent to the initial measurement of the asset retirement obligation, the obligation is adjusted at the end of each period to reflect the passage of time and changes in the estimated future cash flows underlying the obligation. The Company records the retirement obligation on towers owned and cell site improvements where there is a legal obligation to remove the tower or cell site improvements and restore the site to its original condition. The terms associated with its operating leases, and applicable zoning ordinances of certain jurisdictions, define the Company’s obligations which are estimated and vary based on the size of the towers. The Company’s cost to remove the tower or cell site improvements is amortized over the life of the tower or cell site assets.

Goodwill and intangible assets

Goodwill and intangible assets: In connection with the acquisition of a business, a portion of the purchase price may be allocated to identifiable intangible assets with indefinite lives, such as franchise rights, and goodwill, which is an asset representing the future economic benefits arising from other assets acquired in a business combination that are not individually identified and separately recognized. Goodwill is recorded in the segment that was affected by the acquisition.

Goodwill is not amortized but is tested for impairment on at least an annual basis. Impairment testing is required more often than annually if an event or circumstance indicates that impairment is more likely than not to have occurred. In conducting its annual impairment testing, the Company may first perform a qualitative assessment of whether it is more likely than not that a reporting unit’s fair value is less than its carrying amount. If not, no further goodwill impairment testing is required. If it is more likely than not that a reporting unit’s fair value is less than its carrying amount, or if the Company elects not to perform a qualitative assessment of a reporting unit, the Company then compares the fair value of the reporting unit to the related net book value. If the net book value of a reporting unit exceeds its fair value, an impairment loss is measured and recognized. The Company elected not to perform the qualitative assessment and performed a quantitative test comparing the fair value with the carrying amounts and concluded that no impairment existed as of October 1, 2016.

Intangible assets with indefinite lives, primarily cable franchise rights, are assessed annually, at November 1, for impairment and in interim periods if certain triggering events occur indicating that the carrying value may be impaired.

Deferred charges and other assets

Deferred charges and other assets: Deferred charges and other assets consist of derivatives used for hedging purposes and debt issuance costs related to available lines of credit and other unused funds, which are amortized on a straight-line method over the remaining draw period.

Retirement plans

Retirement plans: The Company maintains a Supplemental Executive Retirement Plan (“SERP”) for selected employees. This is an unfunded defined contribution plan. The Company created and funded a rabbi trust to hold assets equal to the liabilities under this plan. Participant balances and earnings thereon continue to be maintained for this plan, but no new participants or contributions have been added to the plan since 2010.

Through the Company’s acquisition of nTelos, the Company assumed nTelos’ non-contributory defined benefit pension plan (“Pension Plan”) covering all employees who met eligibility requirements and were employed by nTelos prior to October 1, 2003. The Pension Plan was closed to nTelos employees hired on or after October 1, 2003. Pension benefits vest after five years of plan service and are based on years of service and an average of the five highest consecutive years of compensation subject to certain reductions if the employee retires before reaching age 65 and elects to receive the benefit prior to age 65. Effective December 31, 2012, nTelos froze future benefit accruals. The Company uses updated mortality tables published by the Society of Actuaries that predict increasing life expectancies in the United States.

IRC Sections 412 and 430 and Sections 302 and 303 of the Employee Retirement Income Security Act of 1974, as amended establish minimum funding requirements for defined benefit pension plans. The minimum required contribution is generally equal to the target normal cost plus the shortfall amortization installments for the current plan year and each of the six preceding plan years less any calculated credit balance. If plan assets (less calculated credits) are equal to or exceed the funding target, the minimum required contribution is the target normal cost reduced by the excess funding, but not below zero. The Company’s policy is to make contributions to stay at or above the threshold required in order to prevent benefit restrictions and related additional notice requirements and is intended to provide not only for benefits based on service to date, but also for those expected to be earned in the future.

The Company’s share of the projected cost of benefits that will be paid after retirement is generally being accrued by charges to expense over the eligible employees’ service periods to the dates they are fully eligible for benefits.

The Company records annual amounts relating to the Pension Plan and postretirement benefit plan based on calculations that incorporate various actuarial and other assumptions, including discount rates, mortality, assumed rates of return, turnover rates and healthcare cost trend rates. The Company reviews its assumptions on an annual basis and makes modifications to the assumptions based on current rates and trends when it is appropriate to do so. We recognize gains and losses on pension and postretirement plan assets and obligations immediately in our operating results. These gains and losses are measured annually at December 31 and accordingly are recorded during the fourth quarter, unless earlier re-measurements are required.

The Company maintains a defined contribution 401(k) plan under which substantially all employees may defer a portion of their earnings on a pretax basis, up to the allowable federal maximum annual contribution amount. The Company may make matching and discretionary contributions to this plan. The Company acquired nTelos' defined contribution 401(k) plan at the time of the acquisition. The nTelos plan was merged into the Company's plan as of December 31, 2016.

None of these plans directly hold Company common stock in their investment portfolios.

Income taxes

Income taxes: Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. The Company evaluates the recoverability of tax assets generated on a state-by-state basis from net operating losses apportioned to that state. Management uses a more likely than not threshold to make that determination and has concluded that at December 31, 2016 and 2015, a valuation allowance against certain state deferred tax assets is necessary, as discussed in Note 6.

Revenues are recognized by the Company based on the various types of transactions generating the revenue. For services, revenue is recognized as the services are performed. For equipment sales, revenue is recognized when the sales transaction is complete.

Under the Sprint Management Agreement, postpaid wireless service revenues are reported net of an 8% Management Fee and an 8.6% Net Service Fee, retained by Sprint. Prepaid wireless service revenues are reported net of a 6% Management Fee retained by Sprint.

Under the Company’s amended affiliate agreement, Sprint agreed to waive the management fee, which is historically presented as a contra-revenue by the Company, for a period of approximately six years. The impact of Sprint’s waiver of the management fee over the approximate six-year period is reflected as an increase in revenue, offset by the non-cash adjustment to recognize this impact on a straight-line basis over the contract term of approximately 14 years.

Earnings per share

Earnings per share: Basic net income(loss) per share was computed on the weighted average number of shares outstanding. Diluted net income per share was computed under the treasury stock method, assuming the conversion as of the beginning of the period, for all dilutive stock options.

There were no adjustments to net income in the computation of diluted earnings per share for any of the years presented.

Contingencies

Contingencies: The Company is involved in various claims and legal actions arising in the ordinary course of business. In the opinion of management, the ultimate disposition of these matters will not have a material adverse effect on the Company’s consolidated financial position, results of operations, or liquidity.

Adoption of New Accounting Principles

During 2016, the Company adopted four recent accounting principles: Accounting Standards Update 2015-3, “Interest – Imputation of Interest” (ASU 2015-3), ASU 2015-17, “Balance Sheet Classification of Deferred Taxes”, ASU 2016-9, “Improvements to Employee Share-based Payment Accounting,” and ASU 2015-16, “Simplifying the Accounting for Measurement-Period Adjustments.”

ASU 2015-3 requires that premiums, discounts, and loan fees and costs associated with long term debt be reflected as a reduction of the outstanding debt balance. Previous guidance had treated such loan fees and costs as a deferred charge on the balance sheet. As a result of implementing ASU 2015-3, the Company reclassified $1.6 million of unamortized loan fees and costs included in deferred charges and other assets as of December 31, 2015 to long-term debt. Approximately $0.5 million was allocated to current maturities of long-term debt, and $1.1 million to long term debt. Total assets, as well as total liabilities and shareholders’ equity, were also reduced by the same $1.6 million. In addition, the Company reclassified $4.3 million of unamortized loan fees and costs included in deferred charges and other assets to long term debt in connection with the new Term loan A-1 and A-2 borrowing related to the acquisition of nTelos. Total assets, as well as total liabilities and shareholders’ equity, were also reduced by the same $4.3 million. There was no impact on the statements of income or cash flows.

ASU 2015-17 simplifies accounting for deferred taxes by eliminating the requirement to present deferred tax assets and liabilities as current and non-current in a classified balance sheet. Due to the immaterial balance of current deferred tax assets ($0.9 million as of December 31, 2015), the Company has elected to apply this guidance prospectively, and thus prior periods have not been retrospectively adjusted.

ASU 2016-9 simplifies certain provisions related to the accounting for the tax effects of stock-based compensation transactions. In particular for the Company, it eliminates the requirement to determine for each award whether the difference between book compensation and tax compensation results in an excess tax benefit or a tax deficiency, which generally speaking, result in an entry to additional paid-in-capital. Under the new guidance, all tax effects for exercised or vested awards are recognized as discrete items in income tax expense, and the Company recognized $1.7 million of tax benefits through income tax expense in 2016. The new guidance also allows an employer to withhold shares to cover more than the minimum statutory withholding taxes (but not more than the maximum statutory withholding requirements) without causing an equity-classified award to become a liability classified award. The other provisions of the new guidance are either not applicable or have no significant impact on the Company’s accounting for stock-based compensation transactions. The Company has elected to early adopt the new guidance and apply it prospectively to tax effects on share-based compensation transactions.

ASU 2015-16 requires that an acquirer recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. See Note 16 for adjustments recorded during 2016.
