| Business and Summary of Significant Accounting Principles                           | Business and Summary of Significant Accounting PrinciplesIn the following discussion, General Communication, Inc. (“GCI”) and its direct and indirect subsidiaries are referred to as “we,” “us” and “our.”(a)BusinessGCI, an Alaska corporation, was incorporated in 1979. We offer the following services primarily in Alaska:•Postpaid and prepaid wireless telephone services and sale of wireless telephone handsets and accessories,•Video services,•Internet access services,•Wholesale wireless, including postpaid and prepaid wireless plans for resale by other carriers and roaming for certain wireless carriers,•Origination and termination of wireline traffic for certain common carriers,•Local and long-distance telephone service,•Data network services,•Broadband services, including our SchoolAccess® offering to rural school districts, our ConnectMD® offering to rural hospitals and health clinics, and managed video conferencing,•Managed services to certain commercial customers,•Sales and service of dedicated communications systems and related equipment, and•Lease, service arrangements and maintenance of capacity on our fiber optic cable systems used in the transmission of services within Alaska and between Alaska and the remaining United States and foreign countries.(b)Basis of Presentation and Principles of ConsolidationOur consolidated financial statements include the consolidated accounts of GCI and its wholly owned subsidiaries, The Alaska Wireless Network, LLC ("AWN") of which we own a two-third interest and four variable interest entities (“VIEs”) for which we are the primary beneficiary after providing certain loans and guarantees and have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP").  These VIEs are Terra GCI Investment Fund, LLC (“TIF”), Terra GCI 2 Investment Fund, LLC (“TIF 2”), Terra GCI 2-USB Investment Fund, LLC (“TIF 2-USB”) and Terra GCI 3 Investment Fund, LLC (“TIF 3”).  TIF became a VIE on August 30, 2011.  TIF 2 and TIF 2-USB became VIEs on October 3, 2012.  TIF 3 became a VIE on December 11, 2012.  We also include in our consolidated financial statements non-controlling interests in consolidated subsidiaries for which our ownership is less than 100 percent.  All significant intercompany transactions between non-regulated affiliates of our company are eliminated.   Intercompany transactions generated between regulated and non-regulated affiliates of our company are not eliminated in consolidation.(c)Non-controlling InterestsNon-controlling interests represent the equity ownership interests in consolidated subsidiaries not owned by us.  Non-controlling interests are adjusted for contributions, distributions, and earnings (loss) attributable to the non-controlling interest partners of the consolidated entities.  Income and loss is allocated to the non-controlling interests based on the respective partnership agreements.(d)AcquisitionsAWNOn July 22, 2013, we closed the transactions under the Asset Purchase and Contribution Agreement (“Wireless Agreement”) and other related agreements entered into on June 4, 2012 by and among Alaska Communications Systems Group, Inc. (“ACS”), GCI, ACS Wireless, Inc., a wholly owned subsidiary of ACS, GCI Wireless Holdings, LLC, a wholly owned subsidiary of GCI, and AWN, pursuant to which the parties agreed to contribute the respective wireless network assets of GCI, ACS and their affiliates to AWN. AWN provides wholesale services to GCI and ACS. GCI and ACS use the AWN network in order to continue to sell services to their respective retail customers. GCI and ACS continue to compete against each other and other wireless providers in the retail wireless market.Under the terms of the Wireless Agreement, we contributed our wireless network assets and certain rights to use capacity to AWN.  Additionally, ACS contributed its wireless network assets and certain rights to use capacity to AWN. As consideration for the contributed business assets and liabilities, ACS received $100.0 million in cash from GCI, a one-third ownership interest in AWN and entitlements to receive preferential cash distributions totaling $190.0 million over the first four years of AWN’s operations ("Preference Period") contingent on the future cash flows of AWN.  The preferential cash distribution is cumulative and may be paid beyond the Preference Period until the entire $190.0 million is paid. We expect ACS's preferential cash distributions to be higher than that which they would receive from their one-third interest.  We received a two-third ownership interest in AWN, as well as entitlements to receive all remaining cash distributions after ACS’s preferential cash distributions during the Preference Period.  The distributions to each member are subject to adjustment based on the number of ACS and GCI wireless subscribers, with the aggregate adjustment capped at $21.8 million for each member over the Preference Period.  Following the Preference Period, we and ACS will receive distributions proportional to our ownership interests.We accounted for the acquisition of AWN using the acquisition method of accounting for business combinations with GCI treated as the acquiring entity.  Accordingly, the assets and liabilities contributed by ACS were recorded at estimated fair values as of July 23, 2013, using the acquisition method of accounting in accordance with Accounting Standards Codification ("ASC") 805, Business Combinations.  We used a combination of the discounted cash flows and market method to value the wireless licenses.  We used the cost approach to value the acquired fixed assets and rights to use capacity assets.  We used a discounted cash flow method to determine the fair value of the non-controlling interest.  The assets and liabilities contributed to AWN by GCI were measured at their carrying amount immediately prior to the contribution as GCI is maintaining control over the assets and liabilities.The following table summarizes the final purchase price and the estimated fair value of ACS’s assets acquired and liabilities assumed, effective July 23, 2013 (amounts in thousands):Purchase price: Previously ReportedAdjustmentsFinal Purchase Price AllocationCash consideration paid $100,000—100,000Fair value of the one-third ownership interest of AWN 267,642(2,131)265,511Total purchase price $367,642(2,131)365,511     Assets acquired and liabilities assumed:    Acquired assets    Current assets $16,9521116,963Property and equipment, including construction in progress 82,47313882,611Goodwill 140,0818,867148,948Wireless licenses 65,433(5,053)60,380Rights to use capacity 52,636(7,298)45,338Other assets 16,0781,20417,282Fair value of liabilities assumed (6,011)—(6,011)Total fair value of assets acquired and liabilities assumed $367,642(2,131)365,511We modified the initial preliminary AWN purchase price allocation during 2014 as noted in the table above due to additional information received from ACS related to the allocation of ACS' network contributed to AWN that impacted the estimated fair value.Goodwill in the amount of $148.9 million was recorded as a result of the acquisition and assigned to our Wireless segment. Goodwill is calculated as the excess of the consideration transferred over the net assets recognized and represents the estimated future economic benefits arising from other assets acquired that could not be individually identified and separately recognized. The goodwill is primarily the result of synergies expected from the combination.  Other assets is primarily comprised of future capacity receivable.  The acquisition resulted in additional revenues of $50.6 million for the year ended December 31, 2013.  It is impracticable for us to determine the amount of earnings of the acquired business included in our Consolidated Income Statement for the year ended December 31, 2013, due to the significant transfer of personnel, fixed assets and other expenses into and between newly created and historical cost centers that has occurred subsequent to the acquisition.Unaudited pro forma financial information does not purport to be indicative of the actual results that would have occurred if the acquisition had actually been completed on January 1, 2012, nor is it necessarily indicative of the future revenue of the combined company.  The following unaudited pro forma financial information is presented as if the acquisition occurred on January 1, 2012 (amounts in thousands): (unaudited) Years Ended  December 31, 2013 2012Pro forma consolidated revenue$897,270 848,676Supplemental pro forma earnings have not been provided as it would be impracticable due to the nature of GCI's and ACS's respective wireless operations prior to the business combination.  GCI and ACS were unable to disaggregate the components of expenses related to their wireless operations contributed to AWN and thus the amounts would require estimates so significant that the resulting information would not be meaningful. Transaction costs of $1.8 million and $2.9 million were recorded in selling, general and administrative expense in the years ended December 31, 2013 and 2012, respectively.Denali Media HoldingsEffective November 1, 2013 we closed the transactions under the asset purchase agreements, pursuant to which Denali Media Holdings, Corp., a wholly owned subsidiary of GCI, through its wholly owned subsidiaries, Denali Media Anchorage, Corp. and Denali Media Southeast, Corp., agreed to purchase three Alaska broadcast stations: CBS affiliate KTVA-TV of Anchorage and NBC affiliates KATH-TV in Juneau and KSCT-TV of Sitka, for a total of $7.6 million (“Media Agreements”). We accounted for the acquisitions using the acquisition method of accounting for business combinations with GCI treated as the acquiring entity.  We consider these business combinations to be immaterial to our consolidated financial statements. (e)Recently Issued Accounting PronouncementsIn May 2014, the Financial Accounting Standards Board issued Accounting Standards Update ("ASU") No. 2014-09, Revenue from Contracts with Customers, or ASU 2014-09.  This new standard provides guidance for the recognition, measurement and disclosure of revenue resulting from contracts with customers and will supersede virtually all of the current revenue recognition guidance under GAAP.  The standard is effective for the first interim period within annual reporting periods beginning after December 15, 2016.  Early adoption is not permitted.  The standard permits the use of either the retrospective or cumulative effect transition method.  We are currently evaluating the impact of the provisions of this new standard on our financial position and results of operations.(f)Regulatory AccountingWe account for the regulated operations of our incumbent local exchange carrier in accordance with the accounting principles for regulated enterprises.  This accounting recognizes the economic effects of rate regulation by recording cost and a return on investment as such amounts are recovered through rates authorized by regulatory authorities.  Accordingly, plant and equipment is depreciated over lives approved by regulators and certain costs and obligations are deferred based upon approvals received from regulators to permit recovery of such amounts in future years.  Our cost studies and depreciation rates for our regulated operations are subject to periodic audits that could result in a change to recorded revenues.(g)Earnings per Common ShareWe compute net income per share of Class A and Class B common stock using the “two class” method.  Therefore, basic net income per share is computed by dividing net income applicable to common stockholders by the weighted average number of common shares outstanding during the period.  Diluted net income per share is computed by dividing net income by the weighted average number ofcommon and dilutive common equivalent shares outstanding during the period.  The computation of the dilutive net income per share of Class A common stock assumes the conversion of Class B common stock to Class A common stock, while the dilutive net income per share of Class B common stock does not assume the conversion of those shares. Additionally, in applying the “two-class” method, undistributed earnings are allocated to both common shares and participating securities. Our restricted stock grants are entitled to dividends and meet the criteria of a participating security.Undistributed earnings for each year are allocated based on the contractual participation rights of Class A and Class B common shares as if the earnings for the year had been distributed.  In accordance with our Articles of Incorporation, if and when dividends are declared on our common stock in accordance with Alaska corporate law, equivalent dividends shall be paid with respect to the shares of Class A and Class B common stock. Both classes of common stock have identical dividend rights and would therefore share equally in our net assets in the event of liquidation. As such, we have allocated undistributed earnings on a proportionate basis.Earnings per common share (“EPS”) and common shares used to calculate basic and diluted EPS consist of the following (amounts in thousands, except per share amounts): Year Ended December 31, 2014 Class A Class BBasic net income per share:   Numerator:   Allocation of undistributed earnings$6,980 577    Denominator:   Weighted average common shares outstanding38,219 3,162Basic net income attributable to GCI common stockholders per common share$0.18 0.18    Diluted net income per share:   Numerator:   Allocation of undistributed earnings for basic computation$6,980 577Reallocation of undistributed earnings as a result of conversion of Class B to Class A shares577 —Effect of share based compensation that may be settled in cash or shares— (2)Net income adjusted for allocation of undistributed earnings$7,557 575    Denominator:   Number of shares used in basic computation38,219 3,162Conversion of Class B to Class A common shares outstanding3,162 —Unexercised stock options112 —Number of shares used in per share computation41,493 3,162Diluted net income attributable to GCI common stockholders per common share$0.18 0.18 Years Ended December 31, 2013 2012 Class A Class B Class A Class BBasic net income per share:       Numerator:       Allocation of undistributed earnings$8,678 728 8,938 735        Denominator:       Weighted average common shares outstanding37,732 3,166 38,560 3,170Basic net income attributable to GCI common stockholders per common share$0.23 0.23 0.23 0.23        Diluted net income per share:       Numerator:       Allocation of undistributed earnings for basic computation$8,678 728 8,938 735Reallocation of undistributed earnings as a result of conversion of Class B to Class A shares728 — 735 —Reallocation of undistributed earnings as a result of conversion of dilutive securities— (3) — (8)Effect of share based compensation that may be settled in cash or shares— — (13) —Net income adjusted for allocation of undistributed earnings and effect of share based compensation that may be settled in cash or shares$9,406 725 9,660 727        Denominator:       Number of shares used in basic computation37,732 3,166 38,560 3,170Conversion of Class B to Class A common shares outstanding3,166 — 3,170 —Unexercised stock options142 — 158 —Effect of share based compensation that may be settled in cash or shares— — 231 —Number of shares used in per share computation41,040 3,166 42,119 3,170Diluted net income attributable to GCI common stockholders per common share$0.23 0.23 0.23 0.23Weighted average shares associated with outstanding share awards for the years ended December 31, 2014, 2013 and 2012 which have been excluded from the computations of diluted EPS, because the effect of including these share awards would have been anti-dilutive, consist of the following (shares, in thousands): Years Ended December 31, 2014 2013 2012Shares associated with anti-dilutive unexercised stock options29 86 88Share-based compensation that may be settled in cash or shares, the effect of which is anti-dilutive26 90 —Shares associated with contingent awards for the years ended December 31, 2014, 2013 and 2012, which have been excluded from the computations of diluted EPS because the contingencies of these awards have not been met at December 31, 2014, 2013 and 2012, consist of the following (shares in thousands): Years Ended December 31, 2014 2013 2012Shares associated with contingent awards— — 58(h)Common StockFollowing are the changes in issued common stock for the years ended December 31, 2014, 2013 and 2012 (shares, in thousands): Class A Class BBalances at January 1, 201239,296 3,171Class B shares converted to Class A2 (2)Shares issued upon stock option exercises320 —Share awards issued731 —Shares repurchased and retired(1,469) —Shares acquired to settle minimum statutory tax withholding requirements and subsequently retired(337) —Other(9) —Balances at December 31, 201238,534 3,169Class B shares converted to Class A4 (4)Shares issued upon stock option exercises87 —Share awards issued680 —Shares repurchased and retired(1,822) —Shares acquired to settle minimum statutory tax withholding requirements and subsequently retired(147) —Other(37) —Balances at December 31, 201337,299 3,165Class B shares converted to Class A6 (6)Shares issued upon stock option exercises51 —Share awards issued1,267 —Shares repurchased and retired(429) —Shares acquired to settle minimum statutory tax withholding requirements and subsequently retired(196) —Balances at December 31, 201437,998 3,159GCI’s Board of Directors has authorized a common stock buyback program for the repurchase of GCI’s Class A and Class B common stock in order to reduce the outstanding shares of Class A and Class B common stock.  Under the common stock buyback plan approved by GCI’s Board of Directors in 2010 we are authorized to repurchase up to $200.0 million worth of GCI common stock, to increase our repurchase limit $5.0 million per quarter indefinitely and to use stock option exercise proceeds to repurchase additional shares.  If stock repurchases are less than the total approved quarterly amount the difference may be carried forward and used to repurchase additional shares in future quarters.  The cost of the repurchased common stock reduced Common Stock on our Consolidated Balance Sheets.During the years ended December 31, 2014, 2013 and 2012 we repurchased 0.4 million, 1.8 million and 1.5 million shares, respectively, of our Class A common stock under the stock buyback program at a cost of $4.2 million, $15.6 million and $14.0 million, respectively.  Under this program we are currently authorized to make up to $122.2 million of repurchases as of December 31, 2014.  The repurchased stock was constructively retired as of December 31, 2014, 2013 and 2012.We expect to continue the repurchases for an indefinite period dependent on leverage, liquidity, company performance, and market conditions and subject to continued oversight by GCI’s Board of Directors.(i)Redeemable Preferred StockWe have 1,000,000 shares of preferred stock authorized with no shares issued and outstanding at years ended December 31, 2014, 2013 and 2012.(j)Treasury StockWe account for treasury stock purchased for general corporate purposes under the cost method and include treasury stock as a component of Stockholders’ Equity.  Treasury stock purchased with intent to retire (whether or not the retirement is actually accomplished) is charged to Class A or Class B Common Stock.(k)Cash EquivalentsCash equivalents consist of certificates of deposit which have an original maturity of three months or less at the date acquired and are readily convertible into cash.(l)Accounts Receivable and Allowance for Doubtful ReceivablesTrade accounts receivable are recorded at the invoiced amount and do not bear interest. The allowance for doubtful receivables is our best estimate of the amount of probable credit losses in our existing accounts receivable. We base our estimates on the aging of our accounts receivable balances, financial health of specific customers, regional economic data, changes in our collections process, regulatory requirements and our customers’ compliance with Universal Service Administrative Company rules. We review our allowance for doubtful receivables methodology at least annually.Depending upon the type of account receivable our allowance is calculated using a pooled basis with an allowance for all accounts greater than 120 days past due or a specific identification method.  When a specific identification method is used, potentially uncollectible accounts due to bankruptcy or other issues are reviewed individually for collectability.  Account balances are charged off against the allowance when we feel it is probable the receivable will not be recovered. We do not have any off-balance-sheet credit exposure related to our customers.(m)InventoriesWireless handset inventories are stated at the lower of cost or market (net realizable value). Cost is determined using the average cost method. Handset costs in excess of the revenues generated from handset sales, or handset subsidies, are expensed at the time of sale. We do not recognize the expected handset subsidies prior to the time of sale because the promotional discount decision is made at the point of sale and/or because we expect to recover the handset subsidies through service revenue.Inventories of other merchandise for resale and parts are stated at the lower of cost or market. Cost is determined using the average cost method.(n)Property and EquipmentProperty and equipment is stated at cost. Construction costs of facilities are capitalized. Equipment financed under capital leases is recorded at the lower of fair market value or the present value of future minimum lease payments at inception of the lease. Construction in progress represents transmission equipment and support equipment and systems not placed in service on December 31, 2014, that management intends to place in service during 2015.Depreciation is computed using the straight-line method based upon the shorter of the estimated useful lives of the assets or the lease term, if applicable, in the following ranges:Asset CategoryAsset LivesTelephony transmission equipment and distribution facilities5-20 yearsFiber optic cable systems15-25 yearsCable transmission equipment and distribution facilities5-30 yearsSupport equipment and systems3-20 yearsTransportation equipment5-13 yearsProperty and equipment under capital leases12-20 yearsBuildings25 yearsCustomer premise equipment2-20 yearsStudio equipment10-15 yearsAmortization of property and equipment under capital leases is included in Depreciation and Amortization Expense on the Consolidated Income Statements.Repairs and maintenance are charged to expense as incurred. Expenditures for major renewals and betterments are capitalized. Accumulated depreciation is removed and gains or losses are recognized at the time of sales or other dispositions of property and equipment.(o)Intangible Assets and GoodwillGoodwill, cable certificates (certificates of convenience and public necessity), wireless licenses and broadcast licenses are not amortized. Cable certificates represent certain perpetual operating rights to provide cable services. Wireless licenses represent the right to utilize certain radio frequency spectrum to provide wireless communications services.  Broadcast licenses represent the right to broadcast television stations in certain areas. Goodwill represents the excess of cost over fair value of net assets acquired in connection with a business acquisition. All other amortizable intangible assets are being amortized over 2 to 20 year periods using the straight-line method.(p)Impairment of Intangibles, Goodwill, and Long-lived AssetsCable certificates, wireless licenses and broadcast licenses are treated as indefinite-lived intangible assets and are tested annually for impairment or more frequently if events and circumstances indicate that the asset might be impaired.  We are allowed to assess qualitative factors (“Step Zero”) in our annual test over our indefinite-lived intangible assets other than goodwill. The impairment test for identifiable indefinite-lived intangible assets other than goodwill consists of a comparison of the estimated fair value of the intangible asset with its carrying value.  If the carrying value of the intangible asset exceeds its fair value, an impairment loss is recognized in an amount equal to that excess.  After an impairment loss is recognized, the adjusted carrying amount of the asset becomes its new accounting basis.  Impairment testing of our cable certificate and wireless license assets as of October 31, 2014 and 2013, used a direct discounted cash flow method.  Impairment testing of our broadcast license assets as of October 31, 2014 used a direct discounted cash flow method.  We did not perform an impairment test on our broadcast license assets during 2013 since we acquired them in November 2013 when we acquired the television stations pursuant to the Media Agreements.  This approach requires us to make estimates and assumptions including projected cash flows and discount rates.  These estimates and assumptions could have a significant impact on whether an impairment charge is recognized and also the magnitude of any such impairment charge. Our goodwill is tested annually for impairment, and is tested for impairment more frequently if events and circumstances indicate that the assets might be impaired.  In our annual test of goodwill, we are allowed to use Step Zero to determine whether it is more likely than not that goodwill is impaired.  We chose not to apply Step Zero and chose to test for goodwill impairment using the traditional quantitative two-step process.  The first step of the quantitative goodwill impairment test is used to identify potential impairment by comparing the fair value of a reporting unit with its carrying amount.  To determine our reporting units, we evaluate the components one level below the segment level and we aggregate the components if they have similar economic characteristics.  As a result of this assessment, our reporting units are the same as our two reportable segments. If the carrying amount of a reporting unit exceeds its fair value, the second step of the goodwill impairment test compares the implied fair value of the reporting unit's goodwill with the carrying amount of that goodwill.  If the carrying amount of the reporting unit's goodwill exceeds the implied fair value of that goodwill, an impairment loss is recognized in an amount equal to that excess.  The implied fair value of goodwill is determined in the same manner as the amount of goodwill that would be recognized in a business combination.  We use an income approach to determine the fair value of our reporting units for purposes of our goodwill impairment test.  In addition, a market-based approach is used where possible to corroborate the fair values determined by the income approach.  The income approach requires us to make estimates and assumptions including projected cash flows and discount rates.  These estimates and assumptions could have a significant impact on whether an impairment charge is recognized and also the magnitude of any such impairment charge.We completed our annual review and no impairment charge was recorded for the years ended December 31, 2014, 2013 and 2012.Long-lived assets, such as property, plant, and equipment, and purchased intangibles subject to amortization are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset group may not be recoverable.  Recoverability of an asset group to be held and used is measured by a comparison of the carrying amount of an asset group to estimatedundiscounted future cash flows expected to be generated by the asset group.  If the carrying amount of an asset group exceeds its estimated undiscounted future cash flows, an impairment charge is recognized by the amount by which the carrying amount of the asset group exceeds the fair value of the asset group.(q)Amortization and Write-off of Loan FeesDebt issuance costs are deferred and amortized using the effective interest method. If a refinancing or amendment of a debt instrument is a substantial modification, all or a portion of the applicable debt issuance costs are written off.  If a debt instrument is repaid prior to the maturity date we will write-off a proportional amount of debt issuance costs.(r)Other AssetsOther Assets primarily include future capacity receivable, broadcast licenses, equity investments that are accounted for using the equity or cost method, restricted cash, long-term deposits, prepayments, and non-trade accounts receivable.Under the terms of the Wireless Agreement, we acquired from ACS the rights to use additional network capacity which we may draw down in the future. The applicable portion of the future capacity receivable asset will be reclassified to the rights to use capacity asset when the capacity is placed in service and amortized using the straight-line method over the remaining 20 year period.(s)InvestmentsWe hold investments in equity method and cost method investees. Investments in equity method investees are those for which we have the ability to exercise significant influence but do not control and are not the primary beneficiary. Significant influence typically exists if we have a 20% to 50% ownership interest in the venture unless persuasive evidence to the contrary exists. Under this method of accounting, we record our proportionate share of the net earnings or losses of equity method investees and a corresponding increase or decrease to the investment balances. Cash payments to equity method investees such as additional investments, loans and advances and expenses incurred on behalf of investees, as well as payments from equity method investees such as dividends, distributions and repayments of loans and advances are recorded as adjustments to investment balances. Investments in entities in which we have no control or significant influence are accounted for under the cost method. We review our investment portfolio each reporting period to determine whether there are identified events or circumstances that would indicate there is a decline in the fair value that would be considered other than temporary. We recorded no impairment charges to equity method or cost method investments for the years ended December 31, 2014, 2013 and 2012.(t)Asset Retirement ObligationsWe record the fair value of a liability for an asset retirement obligation in the period in which it is incurred in Other Liabilities on the Consolidated Balance Sheets. When the liability is initially recorded, we capitalize a cost by increasing the carrying amount of the related long-lived asset. In periods subsequent to initial measurement, changes in the liability for an asset retirement obligation resulting from revisions to either the timing or the amount of the original estimate of undiscounted cash flows are recognized.  Over time,the liability is accreted to its present value each period, and the capitalized cost is depreciated over the useful life of the related asset.  Upon settlement of the liability, we either settle the obligation for itsrecorded amount or incur a gain or loss upon settlement.The majority of our asset retirement obligations are the estimated cost to remove telephony transmission equipment and support equipment from leased property.  Following is a reconciliation of thebeginning and ending aggregate carrying amounts of our liability for asset retirement obligations (amounts in thousands):Balance at December 31, 2012$16,280Liability incurred5,292Additions upon the close of AWN5,218Accretion expense77Liability settled(65)Balance at December 31, 201326,802Liability incurred4,268Accretion expense1,249Revision in estimate(355)Liability settled(24)Balance at December 31 2014$31,940During the years ended December 31, 2014 and 2013, we recorded additional capitalized costs of $4.3 million and $10.5 million, respectively, in Property and Equipment in Service, Net of Depreciation.Certain of our network facilities are on property that requires us to have a permit and the permit contains provisions requiring us to remove our network facilities in the event the permit is not renewed.  We expect to continually renew our permits and therefore cannot estimate any liabilities associated with such agreements.  A remote possibility exists that we would not be able to successfully renew a permit, which could result in us incurring significant expense in complying with restoration or removal provisions.(u)Revenue RecognitionAll revenues are recognized when the earnings process is complete. Revenue recognition is as follows:•Revenues generated from long-distance service usage and plan fees, Internet service excess usage, and managed services are recognized when the services are provided,•We recognize unbilled revenues when the service is provided based upon minutes of use processed, and/or established rates, net of credits and adjustments,•Video service package fees, local access and Internet service plan fees, and data network revenues are billed in advance, recorded as Deferred Revenue on the balance sheet, and are recognized as the associated service is provided,•Certain of our wireless services offerings have been determined to be revenue arrangements with multiple deliverables. Revenues are recognized as each element is earned based on objective evidence regarding the relative fair value of each element and when there are no undelivered elements that are essential to the functionality of the delivered elements. Revenues generated from wireless service usage and plan fees are recognized when the services are provided. Revenues generated from the sale of wireless handsets and accessories are recognized when the amount is known and title to the handset and accessories passes to the customer. As the non-refundable, up-front activation fee charged to the customer does not meet the criteria as a separate unit of accounting, we allocate the additional arrangement consideration received from the activation fee to the handset (the delivered item) to the extent that the aggregate handset and activation fee proceeds do not exceed the fair value of the handset. Any activation fees not allocated to the handset would be deferred upon activation and recognized as service revenue on a straight-line basis over the expected customer relationship period,•The majority of our equipment sale transactions involve the sale of communications equipment with no other services involved. Such equipment is subject to standard manufacturer warranties and we do not manufacture any of the equipment we sell. In such instances, the customer takes title to the equipment generally upon delivery. We recognize revenue for such transactions when title passes to the customer and the revenue is earned and realizable. On certain occasions we enter into agreements to sell and satisfactorily install or integrate telecommunications equipment for a fixed fee. Customers may have refund rights if the installed equipment does not meet certain performance criteria. We defer revenue recognition until we have received customer acceptance per the contract or agreement, and all other required revenue recognition elements have been achieved. Revenues from contracts with multiple element arrangements, such as those including installation and integration services, are recognized as each element is earned based on objective evidence regarding the relative fair value of each element and when there are no undelivered elements that are essential to the functionality of the delivered elements,•Technical services revenues are derived primarily from maintenance contracts on equipment and are recognized on a prorated basis over the term of the contracts,•We account for fiber capacity Indefeasible Right to Use ("IRU") agreements as an operating lease or service arrangement and we defer the revenue and recognize it ratably over the life of the IRU or as service is rendered,•Access revenue is recognized when earned.  We participate in access revenue pools with other telephone companies.  Such pools are funded by toll revenue and/or access charges regulated by the Regulatory Commission of Alaska ("RCA") within the intrastate jurisdiction and the Federal Communications Commission (“FCC”) within the interstate jurisdiction. Much of the interstate access revenue is initially recorded based on estimates. These estimates are derived from interim financial information, available separation studies and the most recent information available about achieved rates of return. These estimates are subject to adjustment in future accounting periods as additional information becomes available. To the extent that a dispute arises over revenue settlements, our policy is to defer revenue recognition until the dispute is resolved,•We receive grant revenue for the purpose of building communication infrastructure in rural areas.  We defer the revenue and recognize it over the life of the asset that was constructed using grant funds.•We pay cash incentives to ACS when wireless handsets are sold to their retail wireless customers and this incentive is recorded as an offset to revenue, and•Other revenues are recognized when the service is provided.As an Eligible Telecommunications Carrier ("ETC"), we receive support from the Universal Service Fund ("USF") to support the provision of wireline local access and wireless service in high cost areas. In November 2011, the FCC published a final rule that segregated the support methodology for Remote and Urban areas in Alaska.Remote High Cost SupportRemote high cost support is based upon the 2011 support disbursed to Competitive Eligible Telecommunications Carriers (“CETCs”) (“Statewide Support Cap”) providing supported services in Remote Alaska, except AT&T.  On January 1, 2012, the per-line rates paid in the Remote areas were frozen by the USF and cannot exceed $250 per line per month on a study area basis.  Line count growth that causes support to exceed the Statewide Support Cap triggers a pro rata support payment reduction to all subject Alaska CETCs until the support is reduced to the Statewide Support Cap amount.  We accrue estimated program revenue based on current line counts and the frozen per-line rates, reduced as needed by our estimate of the impact of the Statewide Support Cap.  When determining the estimated program revenue accrual, we also consider our assessment of the impact of current FCC regulations and of the potential outcome of FCC proceedings. Our estimated accrued revenue is subject to our judgment regarding the outcome of many variables and is subject to upward or downward adjustment in subsequent periods.Additionally, the FCC determined that Remote support will continue to be based on line counts (subject to the Statewide Support Cap) until the last full month prior to the implementation of a successor funding mechanism. A further rulemaking to consider successor funding mechanisms is underway.Urban High Cost SupportUrban high cost support payments are frozen at the monthly average of the subject CETC’s 2011 annual support and are not dependent upon line counts.  A 20% annual phase down commenced July 1, 2012.The phase down has been capped at 60% and the subject CETCs will continue to receive annual support payments at the 60% level until a successor funding mechanism is implemented. A further rulemaking to consider successor funding mechanisms is underway and once a new funding mechanism is in place the phase down will restart the annual 20% decrease until no support is paid.  We apply the proportional performance revenue recognition method to account for the impact of the declining payments while our level of service provided and associated costs remain constant.  Included in the calculation are the scheduled Urban high cost support payments from October 2011 through July  2017 net of our Urban accounts receivable balance at September 30, 2011.  An equal amount of this result is recognized as Urban support revenue each period.  For both Remote and Urban high cost support revenue, our ability to collect our accrued USF support is contingent upon continuation of the USF program and upon our eligibility to participate in that program, which are subject to change by future regulatory, legislative or judicial actions.  We adjust revenue and the account receivable in the period the FCC makes a program change or we assess the likelihood that such a change has increased or decreased revenue.  We do not recognize revenue related to a particular service area until our ETC status has been approved by the RCA.We recorded high cost support revenue under the USF program of $66.7 million, $55.6 million and 42.8 million for the years ended December 31, 2014, 2013 and 2012, respectively.  At December 31, 2014, we have $47.0 million in high cost accounts receivable.(v)Advertising ExpenseWe expense advertising costs in the period during which the first advertisement appears. Advertising expenses were $5.7 million, $5.2 million and $4.9 million for the years ended December 31, 2014, 2013 and 2012, respectively.(w)LeasesScheduled operating lease rent increases are amortized over the expected lease term on a straight-line basis. Rent holidays are recognized on a straight-line basis over the operating lease term(including any rent holiday period).Leasehold improvements are amortized over the shorter of their economic lives or the lease term. We may amortize a leasehold improvement over a term that includes assumption of a lease renewal ifthe renewal is reasonably assured. Leasehold improvements acquired in a business combination are amortized over the shorter of the useful life of the assets or a term that includes required leaseperiods and renewals that are deemed to be reasonably assured at the date of acquisition. Leasehold improvements that are placed in service significantly after and are not contemplated at or near thebeginning of the lease term are amortized over the shorter of the useful life of the assets or a term that includes required lease periods and renewals that are deemed to be reasonably assured at the date the leasehold improvements are purchased. Leasehold improvements made by us and funded by landlord incentives or allowances under an operating lease are recorded as deferred rent and amortized as reductions to lease expense over the lease term.(x)Interest ExpenseMaterial interest costs incurred during the construction period of non-software capital projects are capitalized.  Interest costs incurred during the development period of a software capital project are capitalized.  Interest is capitalized in the period commencing with the first expenditure for a qualifying capital project and ending when the capital project is substantially complete and ready for its intended use. We capitalized interest costs of $3.6 million, $4.6 million and $2.8 million during the years ended December 31, 2014, 2013 and 2012, respectively.(y)Income TaxesIncome taxes are accounted for using the asset and liability method. Deferred tax assets and liabilities are recognized for their future tax consequences attributable to differences between the financialstatement carrying amounts of existing assets and liabilities and their respective tax basis. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable earningsin the years in which those temporary differences are expected to be recovered or settled. A valuation allowance is recognized if it is more likely than not that some portion or the entire deferred tax assetwill not be realized.(z)Comprehensive IncomeTotal comprehensive income was equal to net income during the years ended December 31, 2014, 2013 and 2012.(aa)Share-based Payment ArrangementsCompensation expense is recognized in the financial statements for share-based awards based on the grant date fair value of those awards. Share-based compensation expense includes an estimate for pre-vesting forfeitures and is recognized over the requisite service periods of the awards on a straight-line basis, which is generally commensurate with the vesting term.We are required to report the benefits associated with tax deductions in excess of recognized compensation cost as a financing cash flow rather than as an operating cash flow.(ab)Use of EstimatesThe preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingentassets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period.  Significant items subject to estimates and assumptions include the allowance for doubtful receivables, unbilled revenues, accrual of the USF high cost Remote area program support, share-based compensation, inventory at lower of cost or market, reserve for future customer credits, liability for incurred but not reported medical insurance claims, valuation allowances for deferred income tax assets, depreciable and amortizable lives of assets, the carrying value of long-lived assets including goodwill, cable certificates, wireless and broadcast licenses, our effective tax rate, purchase price allocations, deferred lease expense, asset retirement obligations, the accrual of Cost of GoodsSold, depreciation and the accrual of contingencies and litigation.  Actual results could differ from those estimates.The accounting estimates related to revenues from the USF high cost Remote area program are dependent on various inputs including our estimate of the Statewide Support Cap, our assessment of the impact of new FCC regulations, and the potential outcome of FCC proceedings.  These inputs are subjective and based on our judgment regarding the outcome of certain variables and are subject to upward or downward adjustment in subsequent periods.(ac)Concentrations of Credit RiskFinancial instruments that potentially subject us to concentrations of credit risk are primarily cash and cash equivalents and accounts receivable. Excess cash is invested in high quality short-term liquid money instruments. December 31, 2014, and 2013, substantially all of our cash and cash equivalents were invested in short-term liquid money instruments and the balances were in excess of Federal Deposit Insurance Corporation insured limits.We have one major customer for the year ended December 31, 2014, see Note 10, “Industry Segment Data” of this Form 10-K.  Our remaining customers are located primarily throughout Alaska. Because of this geographic concentration, our growth and operations depend upon economic conditions in Alaska.(ad)Software Capitalization PolicyInternally used software, whether purchased or developed, is capitalized and amortized using the straight-line method over an estimated useful life of five years. We capitalize certain costs associated with internally developed software such as payroll costs of employees devoting time to the projects and external direct costs for materials and services. Costs associated with internally developed software to be used internally are expensed until the point the project has reached the development stage. Subsequent additions, modifications or upgrades to internal-use software are capitalized only to the extent that they allow the software to perform a task it previously did not perform. Software maintenance and training costs are expensed in the period in which they are incurred. The capitalization of software requires judgment in determining when a project has reached the development stage.(ae)GuaranteesCertain of our customers have guaranteed levels of service.  If an interruption in service occurs we do not recognize revenue for any portion of the monthly service fee that will be refunded to the customer or not billed to the customer due to these service level agreements.Additionally, we have provided certain guarantees to U.S. Bancorp Community Development Corporation (“US Bancorp”), our tax credit investor in our four VIEs.  We have guaranteed the delivery of $56.0 million of New Markets Tax Credits (“NMTC”) to US Bancorp, as well as certain loan and management fee payments between our subsidiaries and the VIEs, for which we are the primary beneficiary.  In the event that the tax credits are not delivered or certain payments not made, we are obligated to provide prompt and complete payment of these obligations.   Please refer to Note 12, Variable Interest Entities, of this Form 10-K, for more information about our NMTC transactions.(af)Classification of Taxes Collected from CustomersWe report sales, use, excise, and value added taxes assessed by a governmental authority that is directly imposed on a revenue-producing transaction between us and a customer on a net basis in our Consolidated Income Statements.  The following are certain surcharges reported on a gross basis in our Consolidated Income Statements (amounts in thousands): Years Ended December 31, 2014 2013 2012Surcharges reported gross$4,252 4,644 5,401(ag)ReclassificationsReclassifications have been made to the prior years' consolidated financial states to conform to classifications used in the current year. |
