	Note 2.  Summary of Significant Accounting Policies
	Principles of Consolidation and Basis of Presentation
	The condensed 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, exercise control.  All significant intercompany accounts and transactions have been eliminated in consolidation.
	In the opinion of management, the accompanying unaudited condensed consolidated financial statements as of and for the three and nine months ended September 30, 2014 and three and nine months ended September 30, 2013 contain all adjustments necessary to present fairly in all material respects the financial position as of September 30, 2014, and the results of operations and cash flows for all periods presented on the respective condensed consolidated financial statements included herein.  The results of operations for the three and nine months ended September 30, 2014 are not necessarily indicative of the results to be expected for the full year.  The accompanying condensed consolidated balance sheet as of December 31, 2013 has been derived from the audited consolidated financial statements included in Part II, Item 8 of the Company’s Annual Report on Form 10-K for the year ended December 31, 2013.
	Accounting Estimates
	The preparation of consolidated financial statements in conformity with U.S. generally accepted accounting principles (U.S. 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 consolidated 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 services are rendered or when products are delivered, installed and functional, as applicable.  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 such revenue in the period in which it is determined that the amounts can be estimated and collection is reasonably assured.
	Cash Equivalents and Marketable Securities
	The Company considers its investment in all highly liquid debt instruments with an original maturity of three months or less, when purchased, to be cash equivalents.  The Company determines the appropriate classification of investment securities at the time of purchase and reevaluates this determination at the end of each reporting period.  Debt securities are classified as held-to-maturity when the Company has the positive intent and ability to hold the securities to maturity and are carried at amortized cost.  Debt securities not classified as held-to-maturity are classified as available-for-sale.  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 September 30, 2014 and December 31, 2013.
	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 in cash reimbursements during the nine months ended September 30, 2014.  As of September 30, 2014, the Company had a $0.8 million receivable for the reimbursable portion of the qualified recoverable expenditures, and the Company’s pledged account balance was $4.2 million. The 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 maintains 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 condensed consolidated statements of income.  Bad debt expense for the three months ended September 30, 2014 and 2013 was $0.2 million and $0.1 million, respectively, and bad debt expense for the nine months ended September 30, 2014 and 2013 was $0.7 million and $0.2 million, respectively.  The Company’s allowance for doubtful accounts was $1.5 million as of September 30, 2014 and December 31, 2013.
	The following table presents a roll-forward of the Company’s allowance for doubtful accounts from December 31, 2013 to September 30, 2014:
						Additions
	(In thousands)		31-Dec-13			Charged to Expense			Charged to Other Accounts			Deductions			30-Sep-14
	Allowance for doubtful accounts		$	1,485		$	729		$	-97		$	-619		$	1,498
	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.  Management believes that no impairment indicators exist as of September 30, 2014 that would require the Company 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 periodically reviews and updates based on historical experiences and future expectations.  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 condensed consolidated balance sheets.  At September 30, 2014 and December 31, 2013, other intangibles were comprised of the following:
				30-Sep-14										31-Dec-13
	(Dollars in thousands)	Estimated Life		Gross Amount					Accumulated Amortization					Gross Amount			Accumulated Amortization
	Customer relationships	5 to 15 yrs		$		103,108				$	-86,151				$	103,153		$	-79,399
	Trademarks and franchise rights	10 to 15 yrs				2,862					-1,638					3,518			-2,201
	Total			$		105,970				$	-87,789				$	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 periodically 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 three or nine months ended September 30, 2014.  Amortization expense for the three months ended September 30, 2014 and 2013 was $2.3 million and $2.5 million, respectively, and amortization expense for the nine months ended September 30, 2014 and 2013 was $6.9 million and $7.4 million, respectively.
	Amortization expense for the remainder of 2014 and for the next five years is expected to be as follows:
	(In thousands)		Customer Relationships			Trademarks and Franchise Rights			Total
	Remainder of 2014		$	2,256		$	41		$	2,297
	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 certain trademarks 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 intangible assets annually on October 1 and whenever adverse events or changes in circumstances indicate that impairment may have occurred.    Management believes there have been no events or circumstances to cause the Company to evaluate the carrying amount of goodwill during the nine months ended September 30, 2014.
	Pension Benefits and Retirement Benefits Other Than Pensions
	The Company sponsors a non-contributory defined benefit pension plan (the “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.
	For the three and nine months ended September 30, 2014 and 2013, the components of the Company’s net periodic benefit income for the Pension Plan were as follows:
		Three Months Ended September 30,						Nine Months Ended September 30,
	(In thousands)	2014			2013			2014			2013
	Service cost	$	-		$	-		$	-		$	-
	Interest cost		656			608			1,968			1,824
	Expected return on plan assets		-1,093			-975			-3,279			-2,926
	Amortization of loss		-			229			-			689
	Net periodic benefit income	$	-437		$	-138		$	-1,311		$	-413
	Pension plan assets were valued at $57.6 million and $57.8 million at September 30, 2014 and December 31, 2013, respectively.  No funding contributions were made in the nine months ended September 30, 2014, and the Company does not expect to make a funding contribution during the remainder of 2014.
	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”).  In July 2014, the Company notified participants that medical benefits under the Other Postretirement Benefit Plans will be discontinued effective December 31, 2014.  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 $10.2 million in the third quarter of 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 estimated cost of the benefit obligation to be transferred to the Pension Plan in the form of supplemental benefit payments on December 31, 2014.  The estimated cost of the transferred benefit obligation is an estimate and subject to change until the the final actuarial determination is made on December 31, 2014, the effective date of the transfer.  The Company does not expect any resulting change in estimate to have a material effect on the Company’s consolidated financial statements for the year ending December 31, 2014.
	For the three and nine months ended September 30, 2014 and 2013, the components of the Company’s net periodic benefit cost (income) for its Other Postretirement Benefit Plans were as follows:
		Three Months Ended September 30,						Nine Months Ended September 30,
	(In thousands)	2014			2013			2014			2013
	Service cost	$	13		$	23		$	38		$	68
	Interest cost		147			121			441			364
	Amortization of loss		8			7			23			21

	The Company recognized expense for certain nonqualified pension plans for each of the three months ended September 30, 2014 and 2013 of $0.1 million, and less than $0.1 million of this expense for each period relates to the amortization of actuarial loss.  Expense for nonqualified pension plans for the nine months ended September 30, 2014 and 2013 was $0.3 million and $0.4 million, respectively, and $0.2 million of this expense for each period relates to the amortization of actuarial loss.
	The total amount reclassified out of accumulated other comprehensive loss related to amortization of actuarial losses for retirement plans for the three months ended September 30, 2014 and 2013 was $0.1 million and $0.3 million, respectively, and $0.2 million and $0.9 million for the nine months ended September 30, 2014 and 2013, respectively, all of which has been reclassified to selling, general and administrative expenses on the condensed consolidated statements of income.
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 condensed 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 is 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 10).  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 and the Company’s 401(k) matching contributions was $1.1 million and $3.2 million for the three months ended September 30, 2014 and 2013, respectively, and $3.1 million and $5.5 million for the nine months ended September 30, 2014 and 2013, respectively, which amounts are included in selling, general and administrative expenses on the condensed consolidated statements of income.
Future charges for equity-based compensation related to instruments outstanding at September 30, 2014 for the remainder of 2014 and for each of the years 2015 through 2019 are estimated to be $0.9 million, $3.0 million, $1.8 million, $0.9 million, $0.2 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.
U.S. 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 Company’s adoption of this ASU in the first quarter of 2014 did not have a material impact on its condensed consolidated balance sheet as of September 30, 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.

	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, including restated segment results for the three and nine months ended September 30, 2013 based on the restructuring of the Company’s operating segments in the first quarter of 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 2. 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 segments 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 operating segments.  The Company did not allocate the curtailment gain of $10.2 million to the segments and this amount is included in corporate unallocated charges for the three and nine month periods ended September 30, 2014 in the table above.

	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 first lien 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 September 30, 2014,  no borrowings were outstanding under the Revolver.
	Pricing of the Credit Facility is currently LIBOR plus 3.25% for the Revolver and Term Loan A and LIBOR plus 3.50% for Term Loan B.  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 that began on September 30, 2013.  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 for 2014, 4.25:1.00 for 2015 and 4.00:1.00 thereafter.  The Credit Facility also sets a minimum interest rate coverage ratio of 3.25:1.00.  At September 30, 2014, the Company’s leverage ratio was 3.67:1.00 and its interest coverage ratio was 7.06:1.00.  The Company was in compliance with its debt covenants as of September 30, 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).  The distributable amount as of September 30, 2014 was $8.5 million.
	In accordance with the terms of the Credit Facility, the Company entered into interest rate swap agreements with a combined notional amount of 50 percent of the aggregate outstanding balance of Term Loan A and Term Loan B.  Under the interest rate swap agreements, the Company swaps one-month LIBOR with a fixed rate of approximately 0.5% for certain agreements entered into in 2012 and 0.8% for certain agreements entered into in 2013.    The combined notional amount under the swap agreements was $185.2 million at September 30, 2014.  The Company recognized a gain on interest rate swap derivatives of $0.3 million for the three months ended September 30, 2014 and a loss of $0.6 million for the three months ended September 30, 2013.  The Company recognized a gain on interest rate swap derivatives of $0.4 million for the nine months ended September 30, 2014 and a loss of $0.1 million for the nine months ended September 30, 2013.
	Total unamortized debt issuance costs associated with the Credit Facility were $5.5 million and $6.6 million as of September 30, 2014 and December 31, 2013, respectively, which amounts are included in deferred charges and other assets on the condensed 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 was $0.4 million for each of the three months ended September 30, 2014 and 2013, and $1.1 million and $0.9 million for the nine months ended September 30, 2014 and 2013, 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.  These credits are recorded in the condensed consolidated statements of income as an offset to interest expense.  The Patronage credits were $0.2 million and $0.4 million for the three months ended September 30, 2014 and 2013, respectively, and $0.5 million and $0.9 million for the nine months ended September 30, 2014 and 2013, respectively.
	The aggregate maturities of the Term Loan A and Term Loan B under the Credit Facility are $1.9 million in the remainder of 2014, $7.7 million in 2015, $7.7 million in 2016, $12.8 million in 2017, $80.3 million in 2018 and $259.9 million thereafter.  The Revolver under the Credit Facility, under which no borrowings are outstanding as of September 30, 2014, matures in full in 2018.
	The Company’s blended average interest rate on its long-term debt for the nine months ended September 30, 2014 was 4.16%.
	On October 24, 2014, the Company received commitments from financial institutions to obtain a senior secured incremental term loan facility of up to $30.0 million (“Term Loan C”).  Subject to customary closing conditions, Term Loan C will be established as an incremental term loan under the Company’s existing Credit Agreement and governed by materially similar terms and conditions with revisions to certain key covenants.  Term Loan C will mature in 2019 with quarterly payments of 1% per annum. The Company expects to close on Term Loan C on or about January 31, 2015 at which time the proposed covenant adjustments will become effective. The Company will use the proceeds from Term Loan C to fund new FTTC projects.
	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 September 30, 2014, the carrying value and accumulated amortization of the related assets were $3.1 million and $1.9 million, respectively.  The Company also has a financing arrangement with a provider of software services related to the upgrading of internal infrastructure, including certain software licenses, which is classified as a capital lease.  The agreement extends through 2015 with payments due annually.  As of September 30, 2014, the carrying value and accumulated depreciation of the related assets were $5.9 million and $1.5 million, respectively.  As of September 30, 2014, the combined total net present value of the Company’s future minimum lease payments is $5.2 million and the principal portion of these capital lease obligations is due as follows:  $0.2 million in the remainder of 2014, $2.4 million in 2015, $2.3 million in 2016, $0.2 million in 2017 and $0.1 million thereafter.

	The fair value of certificates of deposits and corporate, municipal 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, the Company classifies 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 discounted cash flows analysis that schedules out the estimated cash flows for the future debt and interest repayments and applies a discount factor that is adjusted to reflect estimated changes in market conditions and credit factors.
	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 $0.8 million as of September 30, 2014 and $0.7 million as of December 31, 2013, respectively, of which $0.7 million and $0.6 million represents the Company’s investment in CoBank for the respective periods.  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 [Abstract]	'
Earnings Per Share	'
	Note 9.  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 three and nine months ended September 30, 2014 and 2013 are detailed in the following table.

Stock_Plans

Stock Plans	9 Months Ended

Stock Plans [Abstract]	'
Stock Plans	'
	Note 10.  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 September 30, 2014, the maximum number of shares of common stock available for awards under the Equity and Cash Incentive Plan was 5,500,000, and 1,700,184 securities remained available for issuance under the 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 185,296 stock options and 154,381 shares of restricted stock under the Equity and Cash Incentive Plan during the nine months ended September 30, 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 of the outstanding restricted stock awards vest on a graded vesting schedule over a five year period.
	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 stock 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 terminations.    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 nine months ended September 30, 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

	Total stock options outstanding, vested and expected to vest at September 30, 2014	2,096	$	12.41		$	8,477
	The weighted-average grant date fair value per share of stock options granted during the nine months ended September 30, 2014 was $6.67.  The total fair value of options that vested during the nine months ended September 30, 2014 was $0.5 million.  As of September 30, 2014, there was $2.0 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 nine months ended September 30, 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
	Granted during the period	154		15.43
	Vested during the period	-94		11.74
	Forfeited during the period	-56		11.97
	Restricted stock outstanding at September 30, 2014	564	$	12.91
	As of September 30, 2014, there was $4.1 million of total unrecognized compensation cost related to unvested restricted stock awards, which is expected to be recognized over a weighted-average period of 2.2 years.
	In addition to the Equity and Cash Incentive Plan discussed above, the Company has an employee stock purchase plan which commenced in 2011 with 100,000 shares available.  New common shares will be issued for purchases under this plan.  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 nine months ended September 30, 2014, 4,087 shares were issued under the employee stock purchase plan.  Compensation expense associated with the employee stock purchase plan was not material for the nine months ended September 30, 2014.

Income Taxes [Abstract]	'
Income Taxes	'
	Note 11.  Income Taxes
	Income tax expense for the three and nine months ended September 30, 2014 was $6.7 million and $12.4 million, respectively, which represents the federal statutory tax rate applied to pre-tax income and the effects of state income taxes and certain non-deductible charges for each period. The Company’s recurring non-deductible expenses relate primarily to certain non-cash equity-based compensation.
	At September 30, 2014, the Company had federal net operating losses (“NOLs”) of $2.1 million, net of adjustments for unrecognized income tax benefits. The Company’s NOLs, if not utilized to reduce taxable income in future periods, will expire in varying amounts from 2022 through 2034.  Management 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.
	While management believes the Company 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, tax years 2010 and thereafter remain open and subject to federal and state audit examinations.

Commitments And Contingencies	'
	Note 12.  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 condensed consolidated financial statements.
	The Company has purchase commitments relating to capital projects totaling $6.0 million as of September 30, 2014, which are expected to be satisfied during the remainder of 2014.

Summary Of Significant Accounting Policies [Abstract]	'
Principles Of Consolidation And Basis Of Presentation	'
	Principles of Consolidation and Basis of Presentation
	The condensed 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, exercise control.  All significant intercompany accounts and transactions have been eliminated in consolidation.
	In the opinion of management, the accompanying unaudited condensed consolidated financial statements as of and for the three and nine months ended September 30, 2014 and three and nine months ended September 30, 2013 contain all adjustments necessary to present fairly in all material respects the financial position as of September 30, 2014, and the results of operations and cash flows for all periods presented on the respective condensed consolidated financial statements included herein.  The results of operations for the three and nine months ended September 30, 2014 are not necessarily indicative of the results to be expected for the full year.  The accompanying condensed consolidated balance sheet as of December 31, 2013 has been derived from the audited consolidated financial statements included in Part II, Item 8 of the Company’s Annual Report on Form 10-K for the year ended December 31, 2013.
Accounting Estimates	'
	Accounting Estimates
	The preparation of consolidated financial statements in conformity with U.S. generally accepted accounting principles (U.S. 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 consolidated 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 services are rendered or when products are delivered, installed and functional, as applicable.  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 such revenue in the period in which 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 investment in all highly liquid debt instruments with an original maturity of three months or less, when purchased, to be cash equivalents.  The Company determines the appropriate classification of investment securities at the time of purchase and reevaluates this determination at the end of each reporting period.  Debt securities are classified as held-to-maturity when the Company has the positive intent and ability to hold the securities to maturity and are carried at amortized cost.  Debt securities not classified as held-to-maturity are classified as available-for-sale.  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 September 30, 2014 and December 31, 2013.
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 in cash reimbursements during the nine months ended September 30, 2014.  As of September 30, 2014, the Company had a $0.8 million receivable for the reimbursable portion of the qualified recoverable expenditures, and the Company’s pledged account balance was $4.2 million. The 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 maintains 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 condensed consolidated statements of income.  Bad debt expense for the three months ended September 30, 2014 and 2013 was $0.2 million and $0.1 million, respectively, and bad debt expense for the nine months ended September 30, 2014 and 2013 was $0.7 million and $0.2 million, respectively.  The Company’s allowance for doubtful accounts was $1.5 million as of September 30, 2014 and December 31, 2013.
	The following table presents a roll-forward of the Company’s allowance for doubtful accounts from December 31, 2013 to September 30, 2014:
						Additions
	(In thousands)		31-Dec-13			Charged to Expense			Charged to Other Accounts			Deductions			30-Sep-14

Property, Plant And Equipment And Other Long-Lived Assets (Excluding Goodwill And Indefinite-Lived Intangible Assets)	'
	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.  Management believes that no impairment indicators exist as of September 30, 2014 that would require the Company 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 periodically reviews and updates based on historical experiences and future expectations.  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 condensed consolidated balance sheets.  At September 30, 2014 and December 31, 2013, other intangibles were comprised of the following:
				30-Sep-14										31-Dec-13
	(Dollars in thousands)	Estimated Life		Gross Amount					Accumulated Amortization					Gross Amount			Accumulated Amortization
	Customer relationships	5 to 15 yrs		$		103,108				$	-86,151				$	103,153		$	-79,399
	Trademarks and franchise rights	10 to 15 yrs				2,862					-1,638					3,518			-2,201
	Total			$		105,970				$	-87,789				$	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 periodically 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 three or nine months ended September 30, 2014.  Amortization expense for the three months ended September 30, 2014 and 2013 was $2.3 million and $2.5 million, respectively, and amortization expense for the nine months ended September 30, 2014 and 2013 was $6.9 million and $7.4 million, respectively.
	Amortization expense for the remainder of 2014 and for the next five years is expected to be as follows:
	(In thousands)		Customer Relationships			Trademarks and Franchise Rights			Total
	Remainder of 2014		$	2,256		$	41		$	2,297
	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 Indefinite-Lived Intangible Assets
	Goodwill and certain trademarks 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 intangible assets annually on October 1 and whenever adverse events or changes in circumstances indicate that impairment may have occurred.    Management believes there have been no events or circumstances to cause the Company to evaluate the carrying amount of goodwill during the nine months ended September 30, 2014.
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 (the “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.
	For the three and nine months ended September 30, 2014 and 2013, the components of the Company’s net periodic benefit income for the Pension Plan were as follows:
		Three Months Ended September 30,						Nine Months Ended September 30,
	(In thousands)	2014			2013			2014			2013
	Service cost	$	-		$	-		$	-		$	-

	Amortization of loss		-			229			-			689
	Net periodic benefit income	$	-437		$	-138		$	-1,311		$	-413
	Pension plan assets were valued at $57.6 million and $57.8 million at September 30, 2014 and December 31, 2013, respectively.  No funding contributions were made in the nine months ended September 30, 2014, and the Company does not expect to make a funding contribution during the remainder of 2014.
	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”).  In July 2014, the Company notified participants that medical benefits under the Other Postretirement Benefit Plans will be discontinued effective December 31, 2014.  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 $10.2 million in the third quarter of 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 estimated cost of the benefit obligation to be transferred to the Pension Plan in the form of supplemental benefit payments on December 31, 2014.  The estimated cost of the transferred benefit obligation is an estimate and subject to change until the the final actuarial determination is made on December 31, 2014, the effective date of the transfer.  The Company does not expect any resulting change in estimate to have a material effect on the Company’s consolidated financial statements for the year ending December 31, 2014.
	For the three and nine months ended September 30, 2014 and 2013, the components of the Company’s net periodic benefit cost (income) for its Other Postretirement Benefit Plans were as follows:
		Three Months Ended September 30,						Nine Months Ended September 30,
	(In thousands)	2014			2013			2014			2013
	Service cost	$	13		$	23		$	38		$	68
	Interest cost		147			121			441			364
	Amortization of loss		8			7			23			21
	Curtailment gain recognized in net income		-10,207			-			-10,207			-
	Net periodic benefit cost (income)	$	-10,039		$	151		$	-9,705		$	453
	The Company recognized expense for certain nonqualified pension plans for each of the three months ended September 30, 2014 and 2013 of $0.1 million, and less than $0.1 million of this expense for each period relates to the amortization of actuarial loss.  Expense for nonqualified pension plans for the nine months ended September 30, 2014 and 2013 was $0.3 million and $0.4 million, respectively, and $0.2 million of this expense for each period relates to the amortization of actuarial loss.
	The total amount reclassified out of accumulated other comprehensive loss related to amortization of actuarial losses for retirement plans for the three months ended September 30, 2014 and 2013 was $0.1 million and $0.3 million, respectively, and $0.2 million and $0.9 million for the nine months ended September 30, 2014 and 2013, respectively, all of which has been reclassified to selling, general and administrative expenses on the condensed consolidated statements of income.
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 condensed 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 is 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 10).  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 and the Company’s 401(k) matching contributions was $1.1 million and $3.2 million for the three months ended September 30, 2014 and 2013, respectively, and $3.1 million and $5.5 million for the nine months ended September 30, 2014 and 2013, respectively, which amounts are included in selling, general and administrative expenses on the condensed consolidated statements of income.
	Future charges for equity-based compensation related to instruments outstanding at September 30, 2014 for the remainder of 2014 and for each of the years 2015 through 2019 are estimated to be $0.9 million, $3.0 million, $1.8 million, $0.9 million, $0.2 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.
	U.S. 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 Company’s adoption of this ASU in the first quarter of 2014 did not have a material impact on its condensed consolidated balance sheet as of September 30, 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.
