Organization	Note 1. Organization
	Lumos Networks Corp. (“Lumos Networks” or the “Company”) is a fiber-based bandwidth infrastructure and service provider in the Mid-Atlantic region with a network of long-haul fiber, metro Ethernet and Ethernet rings located primarily in Virginia and West Virginia, and portions of Maryland, Pennsylvania, Ohio and Kentucky. The Company serves carrier, business and residential customers over its fiber network offering data, voice and IP services. The Company’s principal products and services include Multiprotocol Label Switching (“MPLS”) based Ethernet, Metro Ethernet (“Metro E”), Fiber to the Cell (“FTTC”) wireless backhaul and fiber transport services, wavelength transport services, IP services and other voice services.
	On October 14, 2011, NTELOS Holdings Corp. (“NTELOS”) announced a distribution date of October 31, 2011 for the spin-off of all of the then issued and outstanding shares of common stock of Lumos Networks, which operated NTELOS’s wireline operations (the “Business Separation”). Prior to and in connection with the Business Separation, following the market close on October 31, 2011, NTELOS effectuated a 1-for-2 reverse stock split (the “Reverse Stock Split”) of its shares of Common Stock, $0.01 par value. The spin-off of Lumos Networks was in the form of a tax-free stock distribution to NTELOS stockholders of record as of the close of business on October 24, 2011, the record date (the “Distribution”). On October 31, 2011, NTELOS distributed one share of Lumos Networks common stock for every share of NTELOS’s common stock outstanding, on a post-Reverse Stock Split basis.
	On November 20, 2013, in a secondary offering of the Company’s common stock, Quadrangle Capital Partners LP. (“Quadrangle”) sold 2,888,939 shares, priced at $20.00 per share. This resulted in Quadrangle’s ownership declining from approximately 26% to approximately 13%. The Company did not receive any proceeds from the offering, and the Company’s total shares outstanding did not change as a result of this offering. All direct costs of this offering, which were primarily legal, printing and accounting fees related to the preparation of the registration statement, which totaled $0.8 million, are included in other expenses in the consolidated statement of income for the year ended December 31, 2013.

Significant Accounting Policies	Dec. 31, 2014
Significant Accounting Policies [Abstract]
Significant Accounting Policies	Note 2. Significant Accounting Policies
	Principles of Consolidation and Basis of Presentation
	The consolidated financial statements include the accounts of the Company, Lumos Networks Operating Company, a wholly-owned subsidiary of the Company, and all of Lumos Networks Operating Company’s wholly-owned subsidiaries and those limited liability corporations where Lumos Networks Operating Company or certain of its subsidiaries, as managing member, exercised control. All significant intercompany accounts and transactions have been eliminated in consolidation.
	Accounting Estimates
	The preparation of consolidated financial statements in conformity with U.S. generally accepted accounting principles (GAAP) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates. Significant items subject to such estimates and assumptions include the useful lives of fixed assets; the allowance for doubtful accounts; the valuation of interest rate swap derivatives, deferred tax assets, marketable securities, asset retirement obligations and equity-based compensation; goodwill impairment assessments and reserves for employee benefit obligations and income tax uncertainties.
	Revenue Recognition
	The Company recognizes revenue when persuasive evidence of an arrangement exists, services are rendered or products are delivered, installed and functional, as applicable, the price to the buyer is fixed and determinable and collectability is reasonably assured. Certain services of the Company require payment in advance of service performance. In such cases, the Company records a service liability at the time of billing and subsequently recognizes revenue ratably over the service period. The Company bills customers certain transactional taxes on service revenues. These transactional taxes are not included in reported revenues as they are recognized as liabilities at the time customers are billed.
	The Company earns revenue by providing services through access to and usage of its networks. Local service revenues are recognized as services are provided. Carrier data revenues are earned by providing switched access and other switched and dedicated services, including wireless roamer management, to other carriers. Revenues for equipment sales are recognized at the point of sale.
	The Company periodically makes claims for recovery of access charges on certain minutes of use terminated by the Company on behalf of other carriers. The Company recognizes revenue in the period when it is determined that the amounts can be estimated and collection is reasonably assured.
	Cash Equivalents and Marketable Securities
	The Company considers its investments in all highly liquid debt instruments with an original maturity of three months or less, when purchased, to be cash equivalents. The Company’s marketable securities at December 31, 2014 and 2013 consist of debt securities not classified as cash equivalents. The Company classifies such debt securities as either held-to-maturity, when the Company has the positive intent and ability to hold the securities to maturity, or available-for-sale. Held-to-maturity debt securities are carried at amortized cost, adjusted for the amortization of premiums or accretion of discounts. Available-for-sale securities are carried at fair value, with the unrealized gains and losses reported in other comprehensive income or loss, net of tax. All of the Company’s debt securities not classified as cash equivalents were classified as available-for-sale securities as of December 31, 2014 and 2013.
	The Company previously utilized a swingline credit facility that it had with its primary commercial bank. This swingline facility was terminated in April 2013, concurrent with the closing of the Company’s debt refinancing (see Note 5). The Company had a book overdraft related to this master cash account of $1.8 million as of December 31, 2012. The Company classified the respective changes in the book overdraft amount in cash flows from operating activities on the consolidated statements of cash flows for the years ended December 31, 2013 and 2012.
	Restricted Cash
	During 2010, the Company received a federal broadband stimulus award to bring broadband services and infrastructure to Alleghany County, Virginia. The total project is $16.1 million, of which 50% (approximately $8 million) is being funded by a grant from the federal government. The project is expected to be completed before September 30, 2015. The Company was required to deposit 100% of its portion for the grant (approximately $8 million) into a pledged account in advance of any reimbursements, which can be drawn down ratably following the grant reimbursement approvals which are contingent on adherence to the program requirements. The Company received $0.1 million, $1.0 million and $2.3 million in the years ended December 31, 2014, 2013 and 2012, respectively, for the reimbursable portion of the qualified recoverable expenditures to date. The Company has a $1.3 million receivable for the reimbursable portion of the qualified recoverable expenditures as of December 31, 2014. At December 31, 2014, the Company’s pledged account balance was $4.2 million. This escrow account is a non-interest bearing account with the Company’s primary commercial bank.
	Trade Accounts Receivable
	The Company sells its services to other communication carriers and to business and residential customers primarily in Virginia and West Virginia and portions of Maryland, Pennsylvania, Ohio and Kentucky. The Company has credit and collection policies to maximize collection of trade receivables and requires deposits on certain sales. The Company estimates an allowance for doubtful accounts based on a review of specific customers with large receivable balances and for the remaining customer receivables the Company uses historical results, current and expected trends and changes in credit policies. Management believes the allowance adequately covers all anticipated losses with respect to trade receivables. Actual credit losses could differ from such estimates. The Company includes bad debt expense in selling, general and administrative expense in the consolidated statements of income. The following table shows the activity in the allowance for doubtful accounts for the years ended December 31, 2014, 2013 and 2012:



	(In thousands)		2014			2013			2012
	Allowance for doubtful accounts, beginning		$	1,485		$	1,822		$	2,822

	Allowance for doubtful accounts, ending		$	1,217		$	1,485		$	1,822

	Property, Plant and Equipment and Other Long-Lived Assets (Excluding Goodwill and Indefinite-Lived Intangible Assets)
	Property, plant and equipment, finite-lived intangible assets and long-term deferred charges are recorded at cost and are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount should be evaluated pursuant to the subsequent measurement guidance described in Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 360-10-35. Impairment is determined by comparing the carrying value of these long-lived assets to management’s best estimate of future undiscounted cash flows expected to result from the use of the assets. If the carrying value exceeds the estimated undiscounted cash flows, the excess of the asset’s carrying value over the estimated fair value is recorded as an impairment charge.

	The Company believes that no impairment indicators exist as of December 31, 2014 that would require it to perform impairment testing for long-lived assets, including property, plant and equipment, long-term deferred charges and finite-lived intangible assets to be held and used.

	Depreciation of property, plant and equipment is calculated on a straight-line basis over the estimated useful lives of the assets, which the Company reviews and updates based on historical experience and future expectations. In 2012, the Company revised the useful lives of certain leasehold improvements as a result of the termination of a building lease and recognized accelerated depreciation costs of $1.4 million as a result of this change in estimate, which is included in depreciation and amortization expense for the year ended December 31, 2012.

	Plant and equipment held under capital leases are amortized on a straight-line basis over the shorter of the lease term or estimated useful life of the asset. Amortization of assets held under capital leases, including certain software licenses, is included with depreciation expense.
	Intangibles with a finite life are classified as other intangibles on the consolidated balance sheets. At December 31, 2014 and 2013, other intangibles were comprised of the following:


				2014						2013
	(Dollars in thousands)	Estimated Life		Gross Amount			Accumulated Amortization			Gross Amount		Accumulated Amortization
	Customer relationships	5 to 15 yrs		$	103,108		$	-88,406		$	103,108	$	-79,399
	Trademarks and franchise rights	10 to 15 yrs			2,862			-1,680			3,563		-2,201
	Total			$	105,970		$	-90,086		$	106,671	$	-81,600


	The Company amortizes its finite-lived intangible assets using the straight-line method unless it determines that another systematic method is more appropriate. The amortization for certain customer relationship intangibles is being recognized using an accelerated amortization method based on the pattern of estimated earnings from these assets.
	The estimated life of amortizable intangible assets is determined from the unique factors specific to each asset and the Company reviews and updates estimated lives based on current events and future expectations. The Company capitalizes costs incurred to renew or extend the term of a recognized intangible asset and amortizes such costs over the remaining life of the asset. No such costs were incurred during the years ended December 31, 2014 or 2013. Amortization expense for the years ended December 31, 2014, 2013 and 2012 was $9.2 million, $9.8 million and $11.1 million, respectively.
	Amortization expense for the next five years is expected to be as follows:


	(In thousands)		Customer Relationships			Trademarks and			Total
	(In thousands)		Customer Relationships			Franchise Rights			Total
	2015			4,644			163			4,807
	2016			2,412			163			2,575
	2017			2,093			163			2,256
	2018			1,781			163			1,944
	2019			1,513			152			1,665

	Goodwill and Indefinite-Lived Intangible Assets

	Goodwill and franchise rights are considered to be indefinite-lived intangible assets. Indefinite-lived intangible assets are not subject to amortization but are instead tested for impairment annually or more frequently if an event indicates that the asset might be impaired. The Company’s policy is to assess the recoverability of indefinite-lived assets annually on October 1 and whenever adverse events or changes in circumstances indicate that impairment may have occurred.
	The Company first considers whether to take a qualitative approach in determining whether it is more likely than not that a reporting unit’s fair value is less than its carrying amount before applying the two-step quantitative goodwill impairment test promulgated by FASB ASC Topic 350. If the Company determines that it is more likely than not that a reporting unit’s fair value is less than its carrying amount or if the Company elects to bypass the qualitative test for a specific period, the two-step process is used to test for goodwill impairment. Step one requires a determination of the fair value of each of the reporting units and, to the extent that the fair value of the reporting unit exceeds its carrying value (including goodwill), the step two calculation of implied fair value of goodwill is not required and no impairment loss is recognized. In testing for goodwill impairment, the Company utilizes a combination of a discounted cash flow model and a market approach that includes the use of comparable multiples of publicly traded companies whose services are comparable to ours.
	As described in Note 4, the Company restructured its operating segments in 2014 and, as a result, reassigned goodwill to the new reporting units using a relative fair value allocation approach. As of December 31, 2014, goodwill was attributed to the Company’s segments as follows:


(In thousands)		December 31,
(In thousands)		2014
Data		$	90,561
R&SB			9,736
RLEC Access			-
Total goodwill		$	100,297

As of October 1, 2014, the Company performed its annual goodwill impairment test for each of its reporting units with goodwill, which are two of our three operating segments (data and R&SB). The Company elected to bypass the qualitative assessment due to the restructuring of its operating segments and applied step one of the quantitative test as described above. Based on the results of this annual impairment testing, the Company determined that the fair values of each of the data and R&SB reporting units substantially exceed their respective carrying amounts and that no impairment exists.
The gross amount of goodwill was $133.7 million and the accumulated impairment loss was $33.4 million for a net carrying amount of $100.3 million as of December 31, 2014 and 2013. There was no activity in the consolidated goodwill accounts for the years ended December 31, 2014 and 2013.

Accounting for Asset Retirement Obligations
An asset retirement obligation is evaluated and recorded as appropriate on assets for which the Company has a legal obligation to retire. The Company records a liability for an asset retirement obligation and the associated asset retirement cost capitalized at the time the underlying asset is acquired. 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 enters into various facility collocation agreements and is subject to locality franchise ordinances. The Company constructs assets at these locations and, in accordance with the terms of many of these agreements, the Company is obligated to restore the premises to their original condition at the conclusion of the agreements, generally at the demand of the other party to these agreements. The Company recognizes the fair value of a liability for an asset retirement obligation and capitalizes that cost as part of the cost basis of the related asset, depreciating it over the useful life of the related asset.
Included in certain of the franchise ordinances under which the Company’s RLECs and CLECs operate are clauses that require the removal of the RLEC’s and CLEC’s equipment at the termination of the franchise agreement. The Company has not recognized an asset retirement obligation for these liabilities as the removal of the equipment is not estimable due to an indeterminable end date and the fact that the equipment is part of the public switched telephone network and it is not reasonable to assume the jurisdictions would require its removal.

The following table indicates the changes to the Company’s asset retirement obligation liability, which is included in other long-term liabilities, for the years ended December 31, 2014 and 2013:



(In thousands)		2014			2013
Asset retirement obligations, beginning		$	1,401		$	1,236
Additional asset retirement obligations recorded, net of
adjustments in estimates			-19			61
Accretion of asset retirement obligations			118			104
Asset retirement obligations, ending		$	1,500		$	1,401

Advertising Costs
The Company expenses advertising costs and marketing production costs as incurred (included within selling, general and administrative expenses in the consolidated statements of income). Advertising expense for the years ended December 31, 2014, 2013 and 2012 was $1.4 million, $0.8 million and $1.1 million, respectively.
Pension Benefits and Retirement Benefits Other Than Pensions
The Company sponsors a non-contributory defined benefit pension plan (“Pension Plan”) covering all employees who meet eligibility requirements and were employed prior to 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. The Company froze the Pension Plan effective December 31, 2012. As such, no further benefits are being accrued by participants for services rendered beyond that date.
Sections 412 and 430 of the Internal Revenue Code and ERISA Sections 302 and 303 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 for benefits to be paid in the future.

The Company also provides certain health care and life insurance benefits for retired employees that meet eligibility requirements through two postretirement welfare benefit plans (the “Other Postretirement Benefit Plans”). The health care plan is contributory, with participants’ contributions adjusted annually. The life insurance plan is also contributory. These obligations, along with all of the pension plans and other postretirement benefit plans, are assumed by the Company. Eligibility for the life insurance plan is restricted to active pension participants age 50-64 as of January 5, 1994. Neither plan is eligible to employees hired after April 1993. Effective December 31, 2014, the Company terminated the health care benefits under the Other Postretirement Benefit Plans. Eligible retirees will receive partial compensation for settlement of accrued benefits through a series of supplemental pension payments. As a result, the Company recognized a curtailment gain of $10.8 million in the year ended December 31, 2014 (see Note 11.)

The Company sponsors a contributory defined contribution plan under Internal Revenue Code Section 401(k) for substantially all employees. The Company’s policy is to match 100% of each participant’s annual contributions for contributions up to 1% of each participant’s annual compensation and 50% of each participant’s annual contributions up to an additional 5% of each participant’s annual compensation. Company contributions vest after two years of service.

Operating Leases
The Company has operating leases for administrative office space and equipment, certain of which have renewal options. These leases, with few exceptions, provide for automatic renewal options and escalations that are either fixed or based on the consumer price index. Any rent abatements, along with rent escalations, are included in the computation of rent expense calculated on a straight-line basis over the lease term. The Company’s minimum lease term for most leases includes the initial non-cancelable term and at least one renewal period to the extent that the exercise of the related renewal option or options is reasonably assured. A renewal option or options is determined to be reasonably assured if failure to renew the leases imposes an in-substance economic penalty on the Company. Leasehold improvements are capitalized and depreciated over the shorter of the assets’ useful life or the lease term, including renewal option periods that are reasonably assured.
Income Taxes
Deferred income taxes are provided on an asset and liability method whereby deferred tax assets are recognized for deductible temporary differences and deferred tax liabilities are recognized for taxable temporary differences. Temporary differences are the differences between the reported amounts of assets and liabilities and their tax bases. Deferred tax assets and liabilities are adjusted for the effects of changes in tax laws and rates on the date of enactment. 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. The Company accrues interest and penalties related to unrecognized tax benefits in interest expense and income tax expense, respectively.
Equity-based Compensation
The Company accounts for share-based employee compensation plans under FASB ASC 718, Stock Compensation. Equity-based compensation expense from share-based equity awards is recorded with an offsetting increase to additional paid-in capital on the consolidated balance sheet. For equity awards with only service conditions, the Company recognizes compensation cost on a straight-line basis over the requisite service period for the entire award.
The fair value of common stock options granted with service-only conditions is estimated at the respective measurement date using the Black-Scholes option-pricing model with assumptions related to risk-free interest rate, expected volatility, dividend yield and expected term. The fair value of restricted stock awards granted with service-only conditions is estimated based on the market value of the common stock on the date of grant reduced by the present value of expected dividends as applicable. Certain stock options and restricted shares granted by the Company contain vesting provisions that are conditional on achievement of a target market price for the Company’s common stock. The grant date fair value of these options and restricted shares was adjusted to reflect the probability of the achievement of the market condition based on management’s best estimate using a Monte Carlo model (see Note 9). The Company initially recognizes the related compensation cost for these awards that contain a market condition on a straight-line basis over the requisite service period as derived from the valuation model. The Company accelerates expense recognition if the market conditions are achieved prior to the end of the derived requisite service period.
Total equity-based compensation expense related to all of the share-based awards (Note 9), including the Company’s 401(k) matching contributions, was $4.3 million, $6.8 million and $3.9 million for the years ended December 31, 2014, 2013 and 2012, respectively, which amounts are included in selling, general and administrative expenses in the consolidated statements of income.
Future charges for equity-based compensation related to instruments outstanding at December 31, 2014 for the years 2015 through 2019 are estimated to be $3.4 million, $3.4 million, $2.3 million, $0.5 million and less than $0.1 million, respectively.
Fair Value Measurements
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. When determining the fair value measurements for assets and liabilities required to be recorded at fair value or for certain financial instruments for which disclosure of fair value is required, the Company uses fair value techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible. However, in situations where there is little, if any, market activity for the asset or liability at the measurement date, the fair value measurement reflects the Company’s own judgments about the assumptions that market participants would use in pricing the asset or liability. Those judgments are developed by the Company based on the best information available in the circumstances, including expected cash flows and appropriately risk-adjusted discount rates, available observable and unobservable inputs.
GAAP establishes a fair value hierarchy with three levels of inputs that may be used to measure fair value:

•	Level 1 – Unadjusted quoted prices in active markets for identical assets or liabilities.
•	Level 2 – Unadjusted quoted prices for similar assets or liabilities in active markets, or unadjusted quoted prices for identical or similar assets or liabilities in markets that are not active, or other inputs other than quoted prices that are observable for the asset or liability.
•	Level 3 – Unobservable inputs for the asset or liability.
Recent Accounting Pronouncements
In July 2013, the FASB issued ASU 2013-11, Income Taxes - Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists, which requires an entity to present an unrecognized tax benefit as a reduction of a deferred tax asset for a net operating loss carryforward, or similar tax loss or tax credit carryforward, rather than as a liability when (1) the uncertain tax position would reduce the NOL or other carryforward under the tax law of the applicable jurisdiction and (2) the entity intends to use the deferred tax asset for that purpose. ASU 2013-11 was effective prospectively for public entities for annual reporting periods beginning after December 15, 2013, and interim reporting periods therein. Prospective application applies to unrecognized tax benefits that exist at the date of adoption and those that arise after adoption. The adoption of this ASU in the first quarter of 2014 did not have a material impact on the Company’s consolidated balance sheet as of December 31, 2014.
In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers, which will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. ASU 2014-09 requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The new standard is effective for the Company on January 1, 2017. Early application is not permitted. The standard permits the use of either the retrospective or cumulative effect transition method. The Company has not yet selected a transition method and is still evaluating the effect that ASU 2014-09 will have on its consolidated financial statements and disclosures.

Disclosures About Segments Of An Enterprise And Related Information	Note 4. Disclosures About Segments of an Enterprise and Related Information
	The Company’s operating segments generally align with its major product and service offerings and coincide with the way that the Company’s chief operating decision makers measure performance and allocate resources. The Company’s chief operating decision makers are its Chief Executive Officer and its Chief Financial Officer (collectively, the “CODMs”). In 2013, the Company had three reportable operating segments: strategic data, legacy voice and access. In January 2014, the Company completed a business reorganization to further focus on the carrier and enterprise business markets while maintaining its commitment to residential and small business customers. Accordingly, the Company has revised its reportable segments to reflect the way the CODMs are managing the business and measuring performance under the new organizational structure. The Company’s current reportable operating segments are Data, Residential and Small Business (“R&SB”) and RLEC Access. A general description of the products and services offered and the customers served by each of these segments is as follows:

	·	Data: This segment includes the Company’s enterprise data (metro Ethernet, dedicated Internet, voice over IP (“VoIP”) and private line), transport, and FTTC product and service groups. These businesses primarily serve enterprise and carrier customers utilizing the Company’s network of long-haul fiber, metro Ethernet and Ethernet rings located primarily in Virginia and West Virginia, and portions of Pennsylvania, Maryland, Ohio and Kentucky.
	·
	·	R&SB: This segment includes the following voice products: local lines, primary rate interface (“PRI”), long distance, toll and directory advertising and other voice services (excluding VoIP which are typically provided to enterprise customers and are included in the Company’s data segment) and the following IP services products: fiber-to-the-premise broadband XL, DSL, integrated access and video. These products are sold to residential and small business customers on the Company’s network and within the Company’s footprint. This segment also provides carrier customers access to our network located in competitive markets.
	·
	·	RLEC Access: This segment provides carrier customers access to the Company’s network within the Company’s RLEC footprint and primarily includes switched access services.
	·

	Summarized financial information concerning the Company’s reportable segments is presented in the following table, which includes restated segment results for the years ended December 31, 2013 and 2012 consistent with the restructuring of the Company’s operating segments in 2014.

		-1		The Company evaluates performance based upon Adjusted EBITDA (a non-GAAP measure), defined by the Company as net income or loss attributable to Lumos Networks Corp. before interest, income taxes, depreciation and amortization, accretion of asset retirement obligations, net income or loss attributable to noncontrolling interests, other income or expenses, equity based compensation charges, acquisition-related charges, amortization of actuarial losses on retirement plans, employee separation charges, restructuring-related charges, gain or loss on settlements and gain or loss on interest rate swap derivatives. See Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations for additional disclosures, including the Company’s reasons for using this non-GAAP financial measure.
	The Company’s CODMs do not currently review total assets by segment since the majority of the assets are shared by the segments and centrally-managed. However, total assets may be allocated to the segments in the future should the CODMs decide to manage the business in that manner. Management does review capital expenditures using success-based metrics that allow the Company to determine which segment product groups are driving investment in the network. Depreciation and amortization expense and certain corporate expenses that are excluded from the measurement of segment profit or loss are not allocated to the segments. The Company did not allocate the curtailment gain of $10.8 million recognized in 2014 due to the discontinuance of certain medical benefits under the postretirement medical plan to the segments and this amount is included in corporate unallocated charges for the year ended December 31, 2014 in the table above.
	The following table provides a reconciliation of operating income to Adjusted EBITDA, as defined by the Company, on a consolidated basis for the years ended December 31, 2014, 2013 and 2012:

		-3		The net pre-tax gain on settlements was recognized in 2012 in connection with the settlement of outstanding matters related to a prior acquisition and the settlement of an outstanding lawsuit (Note 13).
	One of the Company's carrier customers, AT&T, individually accounted for 10% of the Company's total revenue for the year ended December 31, 2014 and 8% of the Company’s total revenue for each of the years ended December 31, 2013 and 2012. Another carrier customer, Verizon, accounted for 8% of the Company’s total revenue for the year ended December 31, 2014 and 10% of the Company’s total revenue for each of the years ended December 31, 2013 and 2012. Revenue from these carrier customers was derived primarily from network access, data transport and fiber to the cell site services.

	Credit Facility
	On April 30, 2013, Lumos Networks Operating Company, a wholly-owned subsidiary of the Company, entered into a $425 million credit facility (the “Credit Facility”). The Credit Facility consists of a $100 million senior secured five-year term loan (the “Term Loan A”), a $275 million senior secured six-year term loan (the “Term Loan B”); and a $50 million senior secured five-year revolving credit facility (the “Revolver”). The proceeds from the Term Loan A and the Term Loan B were used to retire the prior credit facility outstanding amount of approximately $311 million and to pay closing costs and other expenses related to the transaction, with the remaining proceeds available for normal course capital expenditures and working capital purposes. As of December 31, 2014, no borrowings were outstanding under the Revolver.
	On January 2, 2015, the Company entered into a $28 million senior secured incremental term loan facility under the existing Credit Facility “Term Loan C” and amended certain terms of the Credit Facility. The Company will use the net proceeds from Term Loan C to fund new FTTC projects. The amendment includes changes to the maximum leverage ratio and the pricing of the Credit Facility as discussed below.
	Pricing of the Credit Facility, as amended in January 2015, is LIBOR plus 3.00% for the Revolver and Term Loan A and LIBOR plus 3.25% for Term Loan B and C. The Credit Facility does not require a minimum LIBOR rate. The Term Loan A matures in 2018 with quarterly payments of 1.25% per annum from September 30, 2014 through December 31, 2016 and 2.50% per annum thereafter. The Term Loan B matures in 2019 with quarterly payments of 1% per annum beginning on September 30, 2013. The Term Loan C matures in full in 2019 with quarterly payments of 1% per annum beginning on June 30, 2015. The Revolver matures in full in 2018. The Credit Facility is secured by a first priority pledge of substantially all property and assets of Lumos Networks Operating Company and all material subsidiaries, as guarantors, excluding the RLECs.
	The Credit Facility includes various restrictions and conditions, including a maximum leverage ratio of 4.50:1.00 through December 31, 2014. As amended, the Credit Facility sets a maximum leverage ratio of 5.00:1.00 through December 31, 2015, 4.75 in 2016, 4.50 in 2017, 4.25 in 2018 and 4.00:1.00 thereafter. The Credit Facility also sets a minimum interest rate coverage ratio of 3.25:1.00. At December 31, 2014, the Company’s leverage ratio was 3.71:1.00 and its interest coverage ratio was 6.99:1.00. The Company was in compliance with its debt covenants as of December 31, 2014. The Credit Facility has a maximum distributable amount available for restricted payments, including the payment of dividends. The distributable amount was initially set at $12 million and is reduced by restricted payments and certain other items set forth in the Credit Agreement. The distributable amount is increased annually by the greater of $12 million or 75% of free cash flow (as defined under the Credit Agreement). Based on the excess cash flow calculation for the year ended December 31, 2014, the distributable amount was increased by $12 million on January 1, 2015. The distributable amount as of December 31, 2014 was $5.4 million.
	The Company entered into an interest rate swap agreement in 2012, which expires December 31, 2015, whereby the Company swaps one-month LIBOR with a fixed rate of approximately 0.8%. In connection with the aforementioned debt refinancing in April 2013, the Company paid $0.9 million to terminate a portion of this interest rate swap agreement. In accordance with the terms of the Credit Facility, the Company entered into additional interest rate swap agreements in July 2013 to bring the combined notional amount of the interest rate swap agreements up to 50 percent of the aggregate outstanding balance of Term Loan A and Term Loan B. Under the new interest rate swap agreements, the Company swaps one-month LIBOR with a fixed rate of approximately 0.5%. The combined notional amount of the interest rate swap instruments was $184.2 million at December 31, 2014. The Company recognized a net gain on interest rate swap derivatives of $0.5 million for the year ended December 31, 2014 and a net loss of $0.1 million for the year ended December 31, 2013.
	In connection with the refinancing in April 2013, the Company deferred an additional $4.9 million in debt issuance costs and expensed approximately $0.9 million of unamortized debt issuance costs associated with the previous credit facility, which expense is included in other expenses on the consolidated statement of income for the year ended December 31, 2013. Total unamortized debt issuance costs were $5.2 million and $6.6 million as of December 31, 2014 and 2013, respectively, which amounts are included in deferred charges and other assets on the consolidated balance sheets and are being amortized to interest expense over the life of the debt using the effective interest method. Amortization of debt issuance costs for the years ended December 31, 2014, 2013 and 2012 was $1.5 million, $1.3 million and $0.8 million, respectively.
	The Company receives patronage credits from CoBank and certain other of the Farm Credit System lending institutions (collectively referred to as “patronage banks”) which are not reflected in the interest rates above. The patronage banks hold a portion of the credit facility and are cooperative banks that are required to distribute their profits to their members. Patronage credits are calculated based on the patronage banks’ ownership percentage of the credit facility and are received by the Company as either a cash distribution or as equity in the patronage banks. The current patronage credit percentages are 75% in cash and 25% in equity. These credits are recorded in the consolidated statements of income as an offset to interest expense. The patronage credits were $0.7 million, $1.3 million and $1.0 million for the years ended December 31, 2014, 2013 and 2012, respectively.
	The aggregate maturities of the Term Loan A and Term Loan B under the Credit Facility are $7.7 million in 2015, $7.7 million in 2016, $12.8 million in 2017, $80.3 million in 2018 and $259.9 million in 2019. The aggregate maturities of the Term Loan C under the Credit Facility are $0.2 million in 2015, $0.3 million in each of 2016, 2017 and 2018 and $26.9 million in 2019. The revolver under the Credit Facility, under which no borrowings are outstanding as of December 31, 2014, matures in full in 2018.
	The Company’s blended average interest rate on its long-term debt for the year ended December 31, 2014 was 4.05%.
	Capital lease obligations
	In addition to the long-term debt discussed above, the Company has capital leases on vehicles with original lease terms of four to five years. At December 31, 2014, the carrying value and accumulated amortization of the related assets were $3.3 million and $1.9 million, respectively. In 2013, the Company entered into a financing arrangement with a provider of software services related to the upgrading of internal infrastructure, including certain software licenses, which the Company classified as a capital lease. The agreement extends through 2015 with payments due annually. As of December 31, 2014, the carrying value and accumulated depreciation of the related asset were $5.9 million and $1.8 million, respectively. As of December 31, 2014, the combined total net present value of the Company’s future minimum lease payments is $5.0 million and the principal portion of these capital lease obligations was due as follows: $2.5 million in 2015, $2.3 million in 2016, $0.1 million in 2017 and $0.1 million thereafter.

Fair Value Of Financial Instruments	Note 7. Fair Value of Financial Instruments
	The Company’s financial instruments consist of cash and cash equivalents, marketable securities, restricted cash, accounts receivable, accounts payable, capital lease obligations (including the current portion), accrued liabilities, interest rate swap derivatives and the Credit Facility (including the current portion) as of December 31, 2014 and 2013. The carrying values of cash and cash equivalents, restricted cash, accounts receivable, accounts payable, capital lease obligations and accrued liabilities approximated their fair values at December 31, 2014 and 2013. Marketable securities and interest rate swap derivatives are recorded in the consolidated balance sheets at fair value (see Note 3 and Note 5).

	The fair value of corporate and U.S. government debt securities are provided by a third-party pricing service and are estimated using pricing models. The underlying inputs to the pricing models are directly observable from active markets. However, the pricing models used do entail a certain amount of subjectivity and therefore differing judgments in how the underlying inputs are modeled could result in different estimates of fair value. As such, we classify these fair value measurements as Level 2 within the fair value hierarchy. The fair value of interest rate derivatives were derived based on bid prices obtained from the administrative agents as of the measurement date.

	The following table summarizes the carrying amounts and estimated fair values of the components included in the Company’s long-term debt, including the current portion.

	The fair value of the Credit Facility was estimated based on an internal analysis of the forward-looking interest rates as of the measurement date, compared to the forward looking interest rates at inception, assuming no change in the credit profile of the Company or market demand for similar instruments.
	The Company also has certain non-marketable long-term investments for which it is not practicable to estimate fair value with a total carrying value of $0.9 million and $0.7 million as of December 31, 2014 and 2013, respectively, of which $0.8 million and $0.6 million, respectively, represents the Company’s investment in CoBank. This investment is primarily related to patronage distributions of restricted equity and is a required investment related to the portion of the Credit Facility held by CoBank. This investment is carried under the cost method.

Earnings Per Share	Dec. 31, 2014
Earnings Per Share [Abstract]
Earnings Per Share	Note 8. Earnings per Share
	The Company computes basic earnings per share by dividing net income attributable to Lumos Networks Corp. applicable to common shares by the weighted average number of common shares outstanding during the period. The impact on earnings per share of nonvested restricted shares outstanding that contain a non-forfeitable right to receive dividends on a one-to-one per share ratio to common shares is included in the computation of basic earnings per share pursuant to the two-class method. The Company issues restricted shares from time to time with vesting terms that are based on achievement of certain stock price performance conditions. These nonvested restricted shares are excluded from the computation of basic and diluted weighted average shares until the period in which the applicable performance or market conditions are attained. The Company uses the treasury stock method to determine the number of potentially dilutive common shares from stock options and nonvested restricted shares during the period.
	The computations of basic and diluted earnings per share for the years ended December 31, 2014, 2013 and 2012 are as follows:


	(In thousands, except per share amounts)	2014		2013		2012

	Diluted earnings per share	$	0.95	$	0.80	$	0.76
	For the year ended December 31, 2014, the denominator for diluted earnings per common share excludes 598,463 shares related to stock options and 17,383 shares related to restricted stock awards which would be antidilutive for the period. For the year ended December 31, 2013, the denominator for diluted earnings per common share excludes 310,933 shares related to stock options and 20,100 shares related to restricted stock awards which would be antidilutive for the period. For the year ended December 31, 2012, the denominator for diluted earnings per common share excludes 1,546,900 shares related to stock options and 45,324 shares related to restricted stock awards which would be antidilutive for the period.

Stock Plans [Abstract]
Stock Plans	Note 9. Stock Plans
	The Company has an Equity and Cash Incentive Plan administered by the Compensation Committee of the Company’s board of directors, which permits the grant of long-term incentives to employees and non-employee directors, including stock options, stock appreciation rights, restricted stock awards, restricted stock units, incentive awards, other stock-based awards and dividend equivalents. The Equity and Cash Incentive Plan was amended in May 2014 to increase the share reserve by 1,500,000 common shares. As of December 31, 2014, the maximum number of shares of common stock available for awards under the Equity and Cash Incentive Plan is 5,500,000 and 1,529,263 securities remained available for issuance under the Equity and Cash Incentive Plan. Upon the exercise of stock options or upon the grant of restricted stock under the Equity and Cash Incentive Plan, new common shares are issued or treasury stock is reissued.
	The Company issued 298,278 stock options and 212,320 shares of restricted stock under the Equity and Cash Incentive Plan during the year ended December 31, 2014. Options issued to employees with service-only conditions generally vest on a graded vesting schedule over a four to five year period. Options generally cliff vest on the first anniversary of the grant date for non-employee directors. Restricted shares generally cliff vest on the third anniversary of the grant date for employees and generally cliff vest on the first anniversary of the grant date for non-employee directors. Some restricted stock awards vest on a graded vesting schedule over a five year period. Certain stock options and restricted shares granted by the Company contain vesting provisions that are conditional on achievement of a target market price for the Company’s common stock. In 2013, the Company recognized compensation expense totaling $1.8 million related to the accelerated vesting of equity awards for which the target market price had been achieved.
	Dividend rights applicable to restricted stock with service-only vesting conditions are equivalent to the Company’s common stock. Restricted stock awards that vest based on achievement of a market condition are not eligible for dividends during the vesting period unless the Compensation Committee determines otherwise.
	Stock options must be granted under the Equity and Cash Incentive Plan at not less than 100% of fair value on the date of grant and have a maximum life of ten years from the date of grant. Options and other awards under the Equity and Cash Incentive Plan may be exercised in compliance with such requirements as determined by a committee of the board of directors. Substantially all options outstanding were issued at a strike price equal to or greater than the fair value on the date of grant.
	The fair value of each option award with service-only vesting conditions is estimated on the grant date using the Black-Scholes option-pricing model with assumptions related to risk-free interest rate, expected volatility, dividend yield and expected term. The risk-free rate is based on the zero-coupon U.S. Treasury rate in effect at the time of grant, with a term equal to the expected life of the options. For awards granted in 2014, the Company used historical trading prices for its common stock to estimate volatility assumptions. Prior to 2014, the Company used peer group and other publicly available market data to estimate volatility assumptions due to limited trading history of its own common stock. The expected option life represents the period of time that the options granted are expected to be outstanding and is determined using the simplified method. The expected dividend yield is estimated based on the Company’s actual dividend yield at the date of the grant.
	The weighted-average grant date fair value per share of stock options granted during the years ended December 31, 2014, 2013 and 2012 was $6.68, $3.33 and $2.34, respectively. The following weighted-average assumptions were used in estimating the grant date fair value of these awards:


		Year Ended	Year Ended		Year Ended
		31-Dec-14	31-Dec-13		31-Dec-12
	Risk-free interest rate	1.96%	1.34%		1.40%
	Expected volatility	59.52%	44.19%		43.42%
	Expected dividend yield	3.54%	4.70%		5.77%
	Expected term	6.1 years	6.6 years		7 years
	The fair value of each restricted stock award with service-only vesting conditions is based on the closing price of the Company’s common stock on the grant date. The fair value for option awards and restricted stock awards with vesting that is conditional on achievement of market conditions is adjusted to reflect the probability of satisfying the market condition based on a Monte Carlo valuation model.

	The summary of the activity and status of the Company’s stock options for the year ended December 31, 2014 is as follows:


	(In thousands, except per share amounts)	Shares	Weighted-Average Exercise Price per Share			Weighted-Average Remaining Contractual Term	Aggregate Intrinsic Value

No options were exercised during the year ended December 31, 2012. The total fair value of options that vested during the years ended December 31, 2014, 2013 and 2012 was $0.5 million, $2.3 million and $1.1 million, respectively. As of December 31, 2014, there was $2.4 million of total unrecognized compensation cost related to unvested stock options, which is expected to be recognized over a weighted-average period of 3.2 years.
	The summary of the activity and status of the Company’s restricted stock for the year ended December 31, 2014 is as follows:



	(In thousands, except per share amounts)	Shares		Weighted-Average Grant Date Fair Value per Share
	Restricted stock outstanding at December 31, 2013	560	$	11.93

	Forfeited during the period	-56		11.97
	Restricted stock outstanding at December 31, 2014	614	$	13.26
	As of December 31, 2014, there was $4.3 million of total unrecognized compensation cost related to unvested restricted stock awards, which is expected to be recognized over a weighted-average period of 2.1 years. The total fair value of restricted stock awards that vested during the years ended December 31, 2014, 2013 and 2012 was $1.7 million, $4.6 million and $2.2 million, respectively.
	In addition to the Equity and Cash Incentive Plan discussed above, the Company has an employee stock purchase plan which commenced in November 2011 with 100,000 shares available. As of December 31, 2014, 73,570 shares remained available for issuance under the employee stock purchase plan. New common shares will be issued for purchases under this plan or treasury shares will be reissued. Shares are priced at 85% of the closing price on the last trading day of the month and settle on the second business day of the following month. During the year ended December 31, 2014, 7,669 shares were issued under the employee stock purchase plan. Compensation expense associated with the employee stock purchase plan was less than $0.1 million for the years ended December 31, 2014, 2013 and 2012.

As of December 31, 2014, these tax benefits are available to offset future taxable income. The Company recognized tax (benefits) expense of ($5.4 million), $5.5 million and $1.8 million in accumulated other comprehensive income associated with the adjustments to various employee benefit plan liabilities for the years ended December 31, 2014, 2013 and 2012, respectively, in accordance with FASB ASC 715.
	The tax effects of temporary differences that give rise to significant portions of the deferred income tax assets and deferred income tax liabilities at December 31, 2014 and 2013 are presented below:

	Net non-current deferred income tax liability			-87,864			-79,087
	Net deferred income tax liability		$	-82,263		$	-71,798

	At December 31, 2014, the Company had federal net operating losses (“NOLs”) of $28.3 million, net of adjustments for unrecognized income tax benefits (“UTBs”). The Company’s NOLs, if not utilized to reduce taxable income in future periods, will expire in varying amounts from 2022 through 2034. The Company believes that it is more likely than not that the results of future operations will generate sufficient taxable income to realize the deferred tax assets.

	The Company recognizes interest related to UTBs in interest expense and penalties on UTBs in income tax expense. A reconciliation of the change in the UTB balance for the years ended December 31, 2014 and 2013 is as follows:


	(In thousands)		2014			2013
	Balance at beginning of year		$	1,125		$	609
	Additions for tax positions related to the current year			344			291
Increases for tax positions related to prior years			11			554
Statute of limitations expiration			-368			-329
Balance at end of year		$	1,112		$	1,125
All of the Company’s UTBs as of December 31, 2014 and 2013 were adjusted through income tax expense. The Company does not expect to have any material changes to its UTBs over the next twelve months.
While the Company believes it has adequately provided for all tax positions, amounts asserted by taxing authorities could be greater than its accrued position. Accordingly, additional provisions could be recorded in the future as revised estimates are made or the underlying matters are settled or otherwise resolved. In general, the tax years that remain open and subject to federal and state audit examinations are 2011-2013 as of December 31, 2014.

Pension Plans And Other Postretirement Benefits [Abstract]
Pension Plans And Other Postretirement Benefits	Note 11. Pension Plans and Other Postretirement Benefits
	The Company sponsors a non-contributory defined benefit pension plan (“Pension Plan”), as well as non-qualified pension plans and other postretirement benefit plans (“OPEBs”) for its eligible employees. The Company recognized total income of $1.1 million (excluding the curtailment gain discussed below) and $0.7 million in 2014 and 2013, respectively, and total periodic benefit cost of $2.2 million in 2012 for all qualified and non-qualified pension and OPEBs plans. Effective December 31, 2012, the Company froze the accumulation of benefits under the Pension Plan and the supplemental executive retirement plan. As such, no further benefits will be accrued by plan participants for services rendered after that date under either of these plans. Effective December 31, 2014, the Company terminated the health care benefits under the Other Postretirement Benefit Plans. Eligible retirees will receive partial compensation for settlement of accrued benefits through a series of supplemental pension payments. As a result, the Company recognized a curtailment gain of approximately $10.8 million in the year ended December 31, 2014, which was calculated as the decrease in the accumulated benefit obligation resulting from the termination of the medical portion of the Other Postretirement Benefit Plans less unrecognized losses in accumulated other comprehensive loss and less the actuarially determined cost of the benefit obligation that was transferred to the Pension Plan in the form of supplemental benefit payments on December 31, 2014.

	The following tables provide a reconciliation of the changes in the qualified plans’ benefit obligations and fair value of assets and a statement of the funded status as of December 31, 2014, 2013 and 2012 and the classification of amounts recognized in the consolidated balance sheets:

	Net amount recognized in accumulated other comprehensive loss		$	-11,053				$		-2,267			$	-10,251		$	-40			$	-740			$	-904
	The accumulated benefit obligation for the defined benefit pension plan at December 31, 2014 and 2013 was $70.9 million and $57.2 million, respectively. The increase in the projected benefit obligation is primarily attributable to actuarial losses resulting from a decrease in the discount rate from 4.70% at December 31, 2013 to 3.85% at December 31, 2014 and updated mortality tables. The accumulated benefit obligation represents the present value of pension benefits based on service and salary earned to date. The benefit obligation indicated in the table above is the projected benefit obligation which represents the present value of pension benefits taking into account projected future service and salary increases. The projected benefit obligation is equal to the accumulated benefit obligation as of December 31, 2014 and 2013 since the Pension Plan was frozen effective as of December 31, 2012.
	The total amounts reclassified out of accumulated other comprehensive income related to amortization of actuarial losses for the pension and other postretirement benefit plans for the years ended December 31, 2014, 2013 and 2012 were less than $0.1 million, $1.0 million, and $1.5 million, respectively. Amortization of actuarial losses is included in selling, general and administrative expenses on the consolidated statements of income.

	The following table provides the components of net periodic (benefit) expense for the plans for the years ended December 31, 2014, 2013 and 2012:


			Defined Benefit Pension Plan													Other Postretirement Benefit Plans
	(In thousands)		Year Ended				Year Ended December 31, 2013				Year Ended						Year Ended					Year Ended			Year Ended
			December 31, 2014								31-Dec-12						December 31,					31-Dec-13			31-Dec-12

	Net periodic (benefit) expense		$	-1,751			$	-551			$		2,705				$		476			$	604			$	603

	Actuarial gains and losses in excess of 10% of the greater of the benefit obligation and the market-related value of assets are amortized over the average remaining service period of active participants.
	The assumptions used in the measurements of the Company’s benefit obligations at December 31, 2014 and 2013 are shown in the following table:


				Defined Benefit Pension Plan						Other Postretirement Benefit Plans
				31-Dec-14			31-Dec-13			31-Dec-14			31-Dec-13
	Discount rate			3.85	%		4.70	%		3.85	%		4.70	%
	Rate of compensation increase			N/A			N/A			N/A			N/A

The assumptions used in the measurements of the Company’s net income or expense for the consolidated statement of income for the years ended December 31, 2014, 2013 and 2012 were as follows:


			Defined Benefit Pension Plan												Other Postretirement Benefit Plans
			Year Ended			Year Ended				Year Ended						Year Ended					Year Ended				Year Ended
			December 31,			31-Dec-13				December 31,						December 31,					December 31,				31-Dec-12
			2014							2012						2014					2013
Discount rate			4.70	%		3.85	%			4.30		%				4.70		%			3.85		%		4.30	%
Expected return on plan assets			7.75	%		7.75	%			7.75		%				N/A					N/A				N/A
Rate of compensation increase			N/A			N/A				3.00		%				N/A					N/A				N/A

The Company reviews the assumptions noted in the above table annually or more frequently to reflect anticipated future changes in the underlying economic factors used to determine these assumptions. The discount rates assumed reflect the rate at which the Company could invest in high quality corporate bonds in order to settle future obligations. In doing so, the Company utilizes a Citigroup Pension Discount Curve applied against the Company’s estimated defined benefit payments to derive a blended rate. The Citigroup Pension Discount Curve is derived from over 350 Aa corporate bonds. The Company also compares this to a Moody’s ten year Aa bond index for reasonableness.
In developing the expected long-term rate of return assumption for the assets of the Pension Plan, the Company evaluated input from its third party pension plan asset managers, including their review of asset class return expectations and long-term inflation assumptions. The Company also considered the related historical ten-year average asset return at December 31, 2014 as well as considering input from the Company’s third party pension plan asset managers.

The weighted average actual asset allocations by asset category and the fair value by asset category as of December 31, 2014 and 2013 were as follows:


(Dollars in thousands)		31-Dec-14						31-Dec-13
Asset Category		Actual Allocation			Fair Value			Actual Allocation			Fair Value
Large Cap Value		23	%		$	13,120		23	%		$	13,202
Large Cap Blend		11	%			6,622		11	%			6,558
Mid Cap Blend		6	%			3,585		6	%			3,559
Small Cap Blend		4	%			2,511		4	%			2,384

Total		100	%		$	58,403		100	%		$	57,847

The actual and target allocation for plan assets is broadly defined and measured as follows:


		31-Dec-14						31-Dec-13
Asset Category		Actual Allocation			Target Allocation			Actual Allocation			Target Allocation
Equity securities		51	%		50	%		49	%		50	%
Bond securities and cash equivalents		49	%		50	%		51	%		50	%
Total		100	%		100	%		100	%		100	%
It is the Company’s policy to invest pension plan assets in a diversified portfolio consisting of an array of asset classes. The investment risk of the assets is limited by appropriate diversification both within and between asset classes. The assets are primarily invested in investment funds that invest in a broad mix of publicly traded equities, bonds and cash equivalents (and fair value is based on quoted market prices (Level 1 input within the fair value hierarchy previously defined)). The allocation between equity and bonds is reset quarterly to the target allocations. Updates to the allocation are considered in the normal course and changes may be made when appropriate. The bond holdings consist of three bond funds split relatively evenly between these funds at December 31, 2014. At December 31, 2014, the Company believes that there are no material concentrations of risk within the portfolio of plan assets.
The assumed long term return noted above is the target long term return. Overall return, risk adjusted return, and management fees are assessed against a peer group and benchmark indices. Reporting on asset performance is provided quarterly and review meetings are held semi-annually. In addition to normal rebalancing to maintain an adequate cash reserve, projected cash flow needs of the plan are reviewed at least annually to ensure liquidity is properly managed.
The Company did not contribute to the Pension Plan in 2014 or 2013 and does not expect to contribute to the Pension Plan in 2015. The Company expects the net periodic benefit for the Pension Plan in 2015 to be $0.5 million and the expense for the other postretirement benefit plans in 2015 to be less than $0.1 million.
The following estimated future pension benefit payments and other postretirement benefit plan payments which reflect expected future service, as appropriate, are expected to be paid in the years indicated:


(In thousands)		Defined Benefit Pension Plan			Other Postretirement Benefit Plans

Year
2015		$	3,379		$	72
2016			2,978			71

2019			3,189			68
2020-2024			16,965			306
Other Benefit Plans
The Company also has a supplemental executive retirement plan (“SERP”). The Company froze the SERP effective December 31, 2012. As such, no further benefits will be accrued by plan participants for services rendered and the accumulated benefit obligation is equivalent to the projected benefit obligation for periods ending after that date. The projected benefit obligation was $4.9 million, $4.3 million and $4.8 million as of December 31, 2014, 2013 and 2012, respectively. The Company recognized $0.2 million of expense from previously unrecognized loss related to the supplemental executive retirement plan during the year ended December 31, 2014 and $0.3 million during each of the years ended December 31, 2013 and 2012, all of which is included in selling, general and administrative expenses in the consolidated statements of income. The total amount of unrecognized actuarial losses recognized in accumulated other comprehensive income at December 31, 2014 and 2013 related to this plan was $1.4 million, net of income taxes of $0.9 million, and $1.1 million, net of income taxes of $0.7 million, respectively.
The estimated future benefit payments are expected to be $0.2 million annually for each of the years 2015 through 2019 and $1.4 million in aggregate for the years 2020 through 2024.
The Company also has certain other nonqualified postretirement plans assumed from a prior merger. The projected benefit obligation related to these plans at December 31, 2013 was $0.4 million. The Company curtailed the medical benefits under these plans as of December 31, 2014, as such there is no material future obligation associated with these plans.
The Company also sponsors a defined contribution 401(k) plan. The Company’s matching contributions to this plan were $1.0 million, $0.9 million and $0.8 million for the years ended December 31, 2014, 2013 and 2012, respectively. The Company funds its 401(k) matching contributions in shares of the Company’s common stock.

	In December 2012, the Company announced a cost reduction plan (the “Plan”), which involved closing or consolidating certain of its facilities, reducing its workforce and freezing benefits under both its defined benefit pension plan and its executive supplemental retirement plan. The Company recognized a total of $3.0 million in restructuring costs in 2012 related to these initiatives, including severance and separation costs of $2.4 million and lease termination costs of $0.6 million. The Plan was substantially completed as of December 31, 2012. The Company incurred costs of less than $0.1 million in 2013 and no costs in 2014 associated with this plan and does not expect to incur any additional costs.

	Rental expense for all operating leases for the years ended December 31, 2014, 2013 and 2012 was $2.4 million, $2.9 million and $3.5 million, respectively. The total amount committed under these lease agreements at December 31, 2014 is: $0.7 million in 2015, $0.5 million in 2016, $0.8 million in 2017, $0.5 million in 2018, $0.1 million in 2019 and $0.4 million for the years thereafter.
	Other Commitments and Contingencies
	The Company periodically makes claims or receives disputes and is involved in legal actions related to billings to other carriers for access to the Company’s network. The Company does not recognize revenue related to such matters until collection of the claims is reasonably assured. In addition to this, the Company periodically disputes access charges that are assessed by other companies with which the Company interconnects and is involved in other disputes and legal and tax proceedings and filings arising from normal business activities.
	The Company is involved in routine litigation and disputes in the ordinary course of its business. While the results of litigation and disputes are inherently unpredictable, management does not expect that the ultimate costs to resolve these matters will have a material adverse effect on the Company’s consolidated financial position, results of operations or cash flows, and believes that adequate provision for any probable and estimable losses has been made in the Company’s consolidated financial statements.
	The Company has other purchase commitments relating to capital expenditures totaling $8.4 million as of December 31, 2014, which are expected to be satisfied during 2015.
	Separation and Other Agreements with NTELOS
	The Company entered into a series of agreements with NTELOS that were intended to govern the relationship between the Company and NTELOS following the Business Separation, and within such agreements, the companies are required to indemnify each other regarding certain matters. These agreements include commercial service agreements, a separation and distribution agreement, an employee matters agreement, a tax matters agreement, intellectual property agreements and a transition services agreement. During the years ended December 31, 2014, 2013 and 2012, the net expense to the Company related to the transition services agreement was less than $0.1 million, $0.1 million and $1.5 million, respectively.
	Under the tax matters agreement entered into between NTELOS and the Company, the Company is generally required to indemnify NTELOS against any tax resulting from the Distribution to the extent that such tax resulted from any of the following events (among others): (1) an acquisition of all or a portion of our stock or assets, whether by merger or otherwise, (2) any negotiations, understandings, agreements or arrangements with respect to transactions or events that cause the Distribution to be treated as part of a plan pursuant to which one or more persons acquire, directly or indirectly, stock representing a 50% or greater interest in Lumos Networks, (3) certain other actions or failures to act by the Company, or (4) any breach by the Company of certain of its representations or undertakings. The Company’s indemnification obligations to NTELOS and its subsidiaries, officers and directors are not limited by any maximum amount.

Significant Accounting Policies [Abstract]
Principles Of Consolidation And Basis Of Presentation	Principles of Consolidation and Basis of Presentation
	The consolidated financial statements include the accounts of the Company, Lumos Networks Operating Company, a wholly-owned subsidiary of the Company, and all of Lumos Networks Operating Company’s wholly-owned subsidiaries and those limited liability corporations where Lumos Networks Operating Company or certain of its subsidiaries, as managing member, exercised control. All significant intercompany accounts and transactions have been eliminated in consolidation.

Accounting Estimates	Accounting Estimates
	The preparation of consolidated financial statements in conformity with U.S. generally accepted accounting principles (GAAP) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates. Significant items subject to such estimates and assumptions include the useful lives of fixed assets; the allowance for doubtful accounts; the valuation of interest rate swap derivatives, deferred tax assets, marketable securities, asset retirement obligations and equity-based compensation; goodwill impairment assessments and reserves for employee benefit obligations and income tax uncertainties.

Revenue Recognition	Revenue Recognition
	The Company recognizes revenue when persuasive evidence of an arrangement exists, services are rendered or products are delivered, installed and functional, as applicable, the price to the buyer is fixed and determinable and collectability is reasonably assured. Certain services of the Company require payment in advance of service performance. In such cases, the Company records a service liability at the time of billing and subsequently recognizes revenue ratably over the service period. The Company bills customers certain transactional taxes on service revenues. These transactional taxes are not included in reported revenues as they are recognized as liabilities at the time customers are billed.
	The Company earns revenue by providing services through access to and usage of its networks. Local service revenues are recognized as services are provided. Carrier data revenues are earned by providing switched access and other switched and dedicated services, including wireless roamer management, to other carriers. Revenues for equipment sales are recognized at the point of sale.
	The Company periodically makes claims for recovery of access charges on certain minutes of use terminated by the Company on behalf of other carriers. The Company recognizes revenue in the period when it is determined that the amounts can be estimated and collection is reasonably assured.

Cash Equivalents And Marketable Securities	Cash Equivalents and Marketable Securities
	The Company considers its investments in all highly liquid debt instruments with an original maturity of three months or less, when purchased, to be cash equivalents. The Company’s marketable securities at December 31, 2014 and 2013 consist of debt securities not classified as cash equivalents. The Company classifies such debt securities as either held-to-maturity, when the Company has the positive intent and ability to hold the securities to maturity, or available-for-sale. Held-to-maturity debt securities are carried at amortized cost, adjusted for the amortization of premiums or accretion of discounts. Available-for-sale securities are carried at fair value, with the unrealized gains and losses reported in other comprehensive income or loss, net of tax. All of the Company’s debt securities not classified as cash equivalents were classified as available-for-sale securities as of December 31, 2014 and 2013.
	The Company previously utilized a swingline credit facility that it had with its primary commercial bank. This swingline facility was terminated in April 2013, concurrent with the closing of the Company’s debt refinancing (see Note 5). The Company had a book overdraft related to this master cash account of $1.8 million as of December 31, 2012. The Company classified the respective changes in the book overdraft amount in cash flows from operating activities on the consolidated statements of cash flows for the years ended December 31, 2013 and 2012.

Restricted Cash	Restricted Cash
	During 2010, the Company received a federal broadband stimulus award to bring broadband services and infrastructure to Alleghany County, Virginia. The total project is $16.1 million, of which 50% (approximately $8 million) is being funded by a grant from the federal government. The project is expected to be completed before September 30, 2015. The Company was required to deposit 100% of its portion for the grant (approximately $8 million) into a pledged account in advance of any reimbursements, which can be drawn down ratably following the grant reimbursement approvals which are contingent on adherence to the program requirements. The Company received $0.1 million, $1.0 million and $2.3 million in the years ended December 31, 2014, 2013 and 2012, respectively, for the reimbursable portion of the qualified recoverable expenditures to date. The Company has a $1.3 million receivable for the reimbursable portion of the qualified recoverable expenditures as of December 31, 2014. At December 31, 2014, the Company’s pledged account balance was $4.2 million. This escrow account is a non-interest bearing account with the Company’s primary commercial bank.

Trade Accounts Receivable	Trade Accounts Receivable
	The Company sells its services to other communication carriers and to business and residential customers primarily in Virginia and West Virginia and portions of Maryland, Pennsylvania, Ohio and Kentucky. The Company has credit and collection policies to maximize collection of trade receivables and requires deposits on certain sales. The Company estimates an allowance for doubtful accounts based on a review of specific customers with large receivable balances and for the remaining customer receivables the Company uses historical results, current and expected trends and changes in credit policies. Management believes the allowance adequately covers all anticipated losses with respect to trade receivables. Actual credit losses could differ from such estimates. The Company includes bad debt expense in selling, general and administrative expense in the consolidated statements of income. The following table shows the activity in the allowance for doubtful accounts for the years ended December 31, 2014, 2013 and 2012:

	Property, plant and equipment, finite-lived intangible assets and long-term deferred charges are recorded at cost and are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount should be evaluated pursuant to the subsequent measurement guidance described in Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 360-10-35. Impairment is determined by comparing the carrying value of these long-lived assets to management’s best estimate of future undiscounted cash flows expected to result from the use of the assets. If the carrying value exceeds the estimated undiscounted cash flows, the excess of the asset’s carrying value over the estimated fair value is recorded as an impairment charge.

	The Company believes that no impairment indicators exist as of December 31, 2014 that would require it to perform impairment testing for long-lived assets, including property, plant and equipment, long-term deferred charges and finite-lived intangible assets to be held and used.

	Depreciation of property, plant and equipment is calculated on a straight-line basis over the estimated useful lives of the assets, which the Company reviews and updates based on historical experience and future expectations. In 2012, the Company revised the useful lives of certain leasehold improvements as a result of the termination of a building lease and recognized accelerated depreciation costs of $1.4 million as a result of this change in estimate, which is included in depreciation and amortization expense for the year ended December 31, 2012.

	Plant and equipment held under capital leases are amortized on a straight-line basis over the shorter of the lease term or estimated useful life of the asset. Amortization of assets held under capital leases, including certain software licenses, is included with depreciation expense.
	Intangibles with a finite life are classified as other intangibles on the consolidated balance sheets. At December 31, 2014 and 2013, other intangibles were comprised of the following:


				2014						2013
	(Dollars in thousands)	Estimated Life		Gross Amount			Accumulated Amortization			Gross Amount		Accumulated Amortization
	Customer relationships	5 to 15 yrs		$	103,108		$	-88,406		$	103,108	$	-79,399
	Trademarks and franchise rights	10 to 15 yrs			2,862			-1,680			3,563		-2,201
	Total			$	105,970		$	-90,086		$	106,671	$	-81,600


	The Company amortizes its finite-lived intangible assets using the straight-line method unless it determines that another systematic method is more appropriate. The amortization for certain customer relationship intangibles is being recognized using an accelerated amortization method based on the pattern of estimated earnings from these assets.
	The estimated life of amortizable intangible assets is determined from the unique factors specific to each asset and the Company reviews and updates estimated lives based on current events and future expectations. The Company capitalizes costs incurred to renew or extend the term of a recognized intangible asset and amortizes such costs over the remaining life of the asset. No such costs were incurred during the years ended December 31, 2014 or 2013. Amortization expense for the years ended December 31, 2014, 2013 and 2012 was $9.2 million, $9.8 million and $11.1 million, respectively.
	Amortization expense for the next five years is expected to be as follows:

Goodwill And Indefinite-Lived Intangible Assets	Goodwill and Indefinite-Lived Intangible Assets

	Goodwill and franchise rights are considered to be indefinite-lived intangible assets. Indefinite-lived intangible assets are not subject to amortization but are instead tested for impairment annually or more frequently if an event indicates that the asset might be impaired. The Company’s policy is to assess the recoverability of indefinite-lived assets annually on October 1 and whenever adverse events or changes in circumstances indicate that impairment may have occurred.
	The Company first considers whether to take a qualitative approach in determining whether it is more likely than not that a reporting unit’s fair value is less than its carrying amount before applying the two-step quantitative goodwill impairment test promulgated by FASB ASC Topic 350. If the Company determines that it is more likely than not that a reporting unit’s fair value is less than its carrying amount or if the Company elects to bypass the qualitative test for a specific period, the two-step process is used to test for goodwill impairment. Step one requires a determination of the fair value of each of the reporting units and, to the extent that the fair value of the reporting unit exceeds its carrying value (including goodwill), the step two calculation of implied fair value of goodwill is not required and no impairment loss is recognized. In testing for goodwill impairment, the Company utilizes a combination of a discounted cash flow model and a market approach that includes the use of comparable multiples of publicly traded companies whose services are comparable to ours.
	As described in Note 4, the Company restructured its operating segments in 2014 and, as a result, reassigned goodwill to the new reporting units using a relative fair value allocation approach. As of December 31, 2014, goodwill was attributed to the Company’s segments as follows:


	(In thousands)		December 31,
	(In thousands)		2014
	Data		$	90,561
	R&SB			9,736
	RLEC Access			-
	Total goodwill		$	100,297

	As of October 1, 2014, the Company performed its annual goodwill impairment test for each of its reporting units with goodwill, which are two of our three operating segments (data and R&SB). The Company elected to bypass the qualitative assessment due to the restructuring of its operating segments and applied step one of the quantitative test as described above. Based on the results of this annual impairment testing, the Company determined that the fair values of each of the data and R&SB reporting units substantially exceed their respective carrying amounts and that no impairment exists.
	The gross amount of goodwill was $133.7 million and the accumulated impairment loss was $33.4 million for a net carrying amount of $100.3 million as of December 31, 2014 and 2013. There was no activity in the consolidated goodwill accounts for the years ended December 31, 2014 and 2013.


Accounting For Asset Retirement Obligations	Accounting for Asset Retirement Obligations
	An asset retirement obligation is evaluated and recorded as appropriate on assets for which the Company has a legal obligation to retire. The Company records a liability for an asset retirement obligation and the associated asset retirement cost capitalized at the time the underlying asset is acquired. 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 enters into various facility collocation agreements and is subject to locality franchise ordinances. The Company constructs assets at these locations and, in accordance with the terms of many of these agreements, the Company is obligated to restore the premises to their original condition at the conclusion of the agreements, generally at the demand of the other party to these agreements. The Company recognizes the fair value of a liability for an asset retirement obligation and capitalizes that cost as part of the cost basis of the related asset, depreciating it over the useful life of the related asset.
	Included in certain of the franchise ordinances under which the Company’s RLECs and CLECs operate are clauses that require the removal of the RLEC’s and CLEC’s equipment at the termination of the franchise agreement. The Company has not recognized an asset retirement obligation for these liabilities as the removal of the equipment is not estimable due to an indeterminable end date and the fact that the equipment is part of the public switched telephone network and it is not reasonable to assume the jurisdictions would require its removal.

	The following table indicates the changes to the Company’s asset retirement obligation liability, which is included in other long-term liabilities, for the years ended December 31, 2014 and 2013:



	(In thousands)		2014			2013
	Asset retirement obligations, beginning		$	1,401		$	1,236
	Additional asset retirement obligations recorded, net of

	Accretion of asset retirement obligations			118			104
	Asset retirement obligations, ending		$	1,500		$	1,401


Advertising Costs	Advertising Costs
	The Company expenses advertising costs and marketing production costs as incurred (included within selling, general and administrative expenses in the consolidated statements of income). Advertising expense for the years ended December 31, 2014, 2013 and 2012 was $1.4 million, $0.8 million and $1.1 million, respectively.

Pension Benefits And Retirement Benefits Other Than Pensions	Pension Benefits and Retirement Benefits Other Than Pensions
	The Company sponsors a non-contributory defined benefit pension plan (“Pension Plan”) covering all employees who meet eligibility requirements and were employed prior to 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. The Company froze the Pension Plan effective December 31, 2012. As such, no further benefits are being accrued by participants for services rendered beyond that date.
	Sections 412 and 430 of the Internal Revenue Code and ERISA Sections 302 and 303 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 for benefits to be paid in the future.

	The Company also provides certain health care and life insurance benefits for retired employees that meet eligibility requirements through two postretirement welfare benefit plans (the “Other Postretirement Benefit Plans”). The health care plan is contributory, with participants’ contributions adjusted annually. The life insurance plan is also contributory. These obligations, along with all of the pension plans and other postretirement benefit plans, are assumed by the Company. Eligibility for the life insurance plan is restricted to active pension participants age 50-64 as of January 5, 1994. Neither plan is eligible to employees hired after April 1993. Effective December 31, 2014, the Company terminated the health care benefits under the Other Postretirement Benefit Plans. Eligible retirees will receive partial compensation for settlement of accrued benefits through a series of supplemental pension payments. As a result, the Company recognized a curtailment gain of $10.8 million in the year ended December 31, 2014 (see Note 11.)

	The Company sponsors a contributory defined contribution plan under Internal Revenue Code Section 401(k) for substantially all employees. The Company’s policy is to match 100% of each participant’s annual contributions for contributions up to 1% of each participant’s annual compensation and 50% of each participant’s annual contributions up to an additional 5% of each participant’s annual compensation. Company contributions vest after two years of service.


Operating Leases	Operating Leases
	The Company has operating leases for administrative office space and equipment, certain of which have renewal options. These leases, with few exceptions, provide for automatic renewal options and escalations that are either fixed or based on the consumer price index. Any rent abatements, along with rent escalations, are included in the computation of rent expense calculated on a straight-line basis over the lease term. The Company’s minimum lease term for most leases includes the initial non-cancelable term and at least one renewal period to the extent that the exercise of the related renewal option or options is reasonably assured. A renewal option or options is determined to be reasonably assured if failure to renew the leases imposes an in-substance economic penalty on the Company. Leasehold improvements are capitalized and depreciated over the shorter of the assets’ useful life or the lease term, including renewal option periods that are reasonably assured.

Income Taxes	Income Taxes
	Deferred income taxes are provided on an asset and liability method whereby deferred tax assets are recognized for deductible temporary differences and deferred tax liabilities are recognized for taxable temporary differences. Temporary differences are the differences between the reported amounts of assets and liabilities and their tax bases. Deferred tax assets and liabilities are adjusted for the effects of changes in tax laws and rates on the date of enactment. 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. The Company accrues interest and penalties related to unrecognized tax benefits in interest expense and income tax expense, respectively.

Equity-Based Compensation	Equity-based Compensation
	The Company accounts for share-based employee compensation plans under FASB ASC 718, Stock Compensation. Equity-based compensation expense from share-based equity awards is recorded with an offsetting increase to additional paid-in capital on the consolidated balance sheet. For equity awards with only service conditions, the Company recognizes compensation cost on a straight-line basis over the requisite service period for the entire award.
	The fair value of common stock options granted with service-only conditions is estimated at the respective measurement date using the Black-Scholes option-pricing model with assumptions related to risk-free interest rate, expected volatility, dividend yield and expected term. The fair value of restricted stock awards granted with service-only conditions is estimated based on the market value of the common stock on the date of grant reduced by the present value of expected dividends as applicable. Certain stock options and restricted shares granted by the Company contain vesting provisions that are conditional on achievement of a target market price for the Company’s common stock. The grant date fair value of these options and restricted shares was adjusted to reflect the probability of the achievement of the market condition based on management’s best estimate using a Monte Carlo model (see Note 9). The Company initially recognizes the related compensation cost for these awards that contain a market condition on a straight-line basis over the requisite service period as derived from the valuation model. The Company accelerates expense recognition if the market conditions are achieved prior to the end of the derived requisite service period.
	Total equity-based compensation expense related to all of the share-based awards (Note 9), including the Company’s 401(k) matching contributions, was $4.3 million, $6.8 million and $3.9 million for the years ended December 31, 2014, 2013 and 2012, respectively, which amounts are included in selling, general and administrative expenses in the consolidated statements of income.
	Future charges for equity-based compensation related to instruments outstanding at December 31, 2014 for the years 2015 through 2019 are estimated to be $3.4 million, $3.4 million, $2.3 million, $0.5 million and less than $0.1 million, respectively.

Fair Value Measurements	Fair Value Measurements
	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. When determining the fair value measurements for assets and liabilities required to be recorded at fair value or for certain financial instruments for which disclosure of fair value is required, the Company uses fair value techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible. However, in situations where there is little, if any, market activity for the asset or liability at the measurement date, the fair value measurement reflects the Company’s own judgments about the assumptions that market participants would use in pricing the asset or liability. Those judgments are developed by the Company based on the best information available in the circumstances, including expected cash flows and appropriately risk-adjusted discount rates, available observable and unobservable inputs.
	GAAP establishes a fair value hierarchy with three levels of inputs that may be used to measure fair value:

	•	Level 1 – Unadjusted quoted prices in active markets for identical assets or liabilities.
	•	Level 2 – Unadjusted quoted prices for similar assets or liabilities in active markets, or unadjusted quoted prices for identical or similar assets or liabilities in markets that are not active, or other inputs other than quoted prices that are observable for the asset or liability.
	•	Level 3 – Unobservable inputs for the asset or liability.


Recent Accounting Pronouncements	Recent Accounting Pronouncements
	In July 2013, the FASB issued ASU 2013-11, Income Taxes - Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists, which requires an entity to present an unrecognized tax benefit as a reduction of a deferred tax asset for a net operating loss carryforward, or similar tax loss or tax credit carryforward, rather than as a liability when (1) the uncertain tax position would reduce the NOL or other carryforward under the tax law of the applicable jurisdiction and (2) the entity intends to use the deferred tax asset for that purpose. ASU 2013-11 was effective prospectively for public entities for annual reporting periods beginning after December 15, 2013, and interim reporting periods therein. Prospective application applies to unrecognized tax benefits that exist at the date of adoption and those that arise after adoption. The adoption of this ASU in the first quarter of 2014 did not have a material impact on the Company’s consolidated balance sheet as of December 31, 2014.
	In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers, which will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. ASU 2014-09 requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The new standard is effective for the Company on January 1, 2017. Early application is not permitted. The standard permits the use of either the retrospective or cumulative effect transition method. The Company has not yet selected a transition method and is still evaluating the effect that ASU 2014-09 will have on its consolidated financial statements and disclosures.
