| Consolidation, Variable Interest Entity, Policy [Policy Text Block]                                 | Principles of Consolidation

The consolidated financial statements include the consolidated accounts of GCI, Inc. and its whollyowned subsidiaries, as well as a variable interest entity (“VIE”) in which we were the primary beneficiary, when on August 30, 2011, we provided certain loans and guarantees to Terra GCI Investment Fund, LLC (“TIF”).  We alsoinclude 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.

| New Accounting Pronouncements Policy [Policy Text Block]                                            | Recently Adopted Accounting Pronouncements

Accounting Standards Update (“ASU”) 2011-08, “Intangibles – Goodwill and Other (Topic 350)”   allows an entity to first assess qualitative factors to determine whether it is necessary to perform the two-step quantitative goodwill impairment test. Under these amendments, an entity would not be required to calculate the fair value of a reporting unit unless the entity determines, based on a qualitative assessment, that it is more likely than not that its fair value is less than its carrying amount. The amendments include a number of events and circumstances for an entity to consider in conducting the qualitative assessment.   The adoption of ASU 2011-08 on January 1, 2012 did  not have a material impact on our income statements, financial position or cash flows.

 

ASU 2011-04 “Fair Value Measurement (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and International Financial Reporting Standards (“IFRS”)” amended current guidance to achieve common fair value measurement and disclosure requirements in GAAP and IFRS.  The amendments generally represent clarification of FASB Accounting Standards Codification Topic 820, but also include instances where a particular principle or requirement for measuring fair value or disclosing information about fair value measurements has changed.   The adoption of ASU 2011-04 on January 1, 2012 did not have a material impact on our income statements, financial position or cash flows.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               |

We account for our regulated operations 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.

| Revenue Recognition, Policy [Policy Text Block]                                                     | Revenue Recognition

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. On November 29, 2011, the Federal Communications Commission (“FCC”) published a final rule to reform the methodology for distributing USF high cost support for voice and broadband services, as well as to the access charge regime for terminating traffic between carriers (“High Cost Order”).  The High Cost Order defined the division of support to Alaska between Urban and Remote areas.  The High Cost Order was a significant program change that required a reassessment of our high cost support revenue recognition.

 

Prior to the High Cost Order program changes we accrued Remote and Urban estimated program revenue quarterly based on current line counts, the most current rates paid to us, our assessment of the impact of current FCC regulations, and our assessment 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 adjustments in subsequent periods. 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 is 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.

 

Remote High Cost Support

The High Cost Order mandated that as of January 1, 2012, Remote high cost support is based upon the total 2011 support disbursed to all subject Competitive Eligible Telecommunications Carriers (“CETCs”) (“Statewide Support Cap”).  On January 1, 2012, the rates paid in the Remote areas were mandated and frozen by the USF and cannot exceed $250 per line per month on a study area basis.  Line count growth that causes the Statewide Support Cap to be exceeded triggers a pro rata support payment reduction to all subject Alaska CETCs until the support is reduced down to the Statewide Support Cap amount.  

 

The High Cost Order further mandated that on January 1, 2014, a freeze of Remote support will begin and subject CETC's support payments will be frozen at the monthly average of 2013 annual support.  If a successor funding mechanism is operational on July 1, 2014, a 20% annual phase down will commence decreasing support 20% each annual period until no support is paid starting July 1, 2018.  If a successor funding mechanism is not operational on July 1, 2014, the phase down will not begin and the subject CETCs will continue to receive the monthly average of 2013 annual support until a successor funding mechanism is operational.  A subject CETC may not receive phase down support and support from a successor funding mechanism; one program or the other must be selected.  At this time we cannot predict the likelihood of a successor funding mechanism being operational on July 1, 2014 nor can we predict whether we can or will participate in a successor funding mechanism.

 

As a result of the High Cost Order program changes for the areas designated Remote by the USF, beginning in the fourth quarter of 2011 we accrue estimated program revenue based on current line counts and the rates mandated and frozen by the USF, 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. 

 

Urban High Cost Support

The High Cost Order mandated that as of January 1, 2012, Urban high cost support payments are frozen at the monthly average of the subject CETC's 2011 annual support.  A 20% annual phase down will commence July 1, 2012, decreasing support 20% each annual period until no support is paid starting July 1, 2016.  If a successor funding mechanism is not operational on July 1, 2014, the phase down will stop at 60% and the subject CETCs will continue to receive annual support payments at the 60% level until a successor funding mechanism is operational.  Urban high cost support is no longer dependent upon line counts and line count filings are no longer required.

 

As a result of the High Cost Order program changes for the areas considered to be Urban by the USF 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 June 2014 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.  At this time we cannot predict the likelihood of a successor funding mechanism being operational on July 1, 2014; therefore we have not included projected support payments beyond June 2014. 

 

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 is 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 until our ETC status has been approved by the Regulatory Commission of Alaska.

The 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 contingent assets 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 and wireless licenses, our effective tax rate, purchase price allocations, deferred lease expense, asset retirement obligations, the accrual of Cost of Goods Sold, 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.  Effective in the fourth quarter of 2011, we changed our high cost support revenue recognition methodology due to the High Cost Order.

If a sales transaction has multiple element arrangements (for example, delivery of multiple products, services or the rights to use assets) the disclosure may indicate the accounting policy for each unit of accounting as well as how units of accounting are determined and valued. The disclosure may encompass important judgment as to appropriateness of principles related to recognition of revenue. The disclosure also may indicate the entity's treatment of any unearned or deferred revenue that arises from the transaction.
