Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Background General We are an integrated communications company engaged primarily in providing an array of communications services to our residential and business customers. Our communications services include local voice, broadband, private line (including special access), Ethernet, wavelength, network access, information technology, video and other ancillary services. In certain local and regional markets, we also provide local access and fiber transport services to competitive local exchange carriers. We generate the majority of our total consolidated operating revenues from services provided in the 14-state region of Arizona, Colorado, Idaho, Iowa, Minnesota, Montana, Nebraska, New Mexico, North Dakota, Oregon, South Dakota, Utah, Washington and Wyoming. We refer to this region as our local service area. Basis of Presentation Our consolidated balance sheet as of December 31, 2016, which was derived from our audited consolidated financial statements, and our unaudited interim consolidated financial statements provided herein have been prepared in accordance with the instructions for Form 10-Q. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") have been condensed or omitted pursuant to rules and regulations of the Securities and Exchange Commission ("SEC"); however, in our opinion, the disclosures made are adequate to make the information presented not misleading. We believe that these consolidated financial statements include all normal recurring adjustments necessary to fairly present the results for the interim periods. The consolidated results of operations for the first nine months of the year are not necessarily indicative of the consolidated results of operations that might be expected for the entire year. These consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the notes thereto included in our annual report on Form 10-K for the year ended December 31, 2016. The accompanying consolidated financial statements include our accounts and the accounts of our subsidiaries. Intercompany amounts and transactions with our consolidated subsidiaries have been eliminated. Transactions with our non-consolidated affiliates (referred to herein as affiliates) have not been eliminated. We reclassified certain prior period amounts to conform to the current period presentation. These changes had no impact on total operating revenues, total operating expenses or net income for any period. Recent Accounting Pronouncements Goodwill Impairment On January 26, 2017, The Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update ("ASU") ASU 2017-04, “Simplifying the Test for Goodwill Impairment” (“ASU 2017-04”). ASU 2017-04 simplifies the impairment testing for goodwill by changing the measurement for goodwill impairment. Under current rules, we are required to compute the implied fair value of goodwill to measure the impairment amount if the carrying value of a reporting unit exceeds its fair value. Under ASU 2017-04, the goodwill impairment charge will equal the excess of the reporting unit carrying value above fair value, limited to the amount of goodwill assigned to the reporting unit. We are required to adopt the provisions of ASU 2017-04 for any goodwill impairment tests, including our required annual test, occurring after January 1, 2020, but have the option to early adopt for any impairment test that we are required to perform. We have not determined if we will elect to early adopt the provisions of ASU 2017-04. The provisions of ASU 2017-04 would not have affected our last goodwill impairment assessment, but no assurance can be provided that the simplified testing methodology will not affect our goodwill impairment assessment in the future. Income Taxes On October 24, 2016, the FASB issued ASU 2016-16, “Intra-Entity Transfers of Assets Other Than Inventory” ("ASU 2016-16"). ASU 2016-16 eliminates the current prohibition on the recognition of the income tax effects on the transfer of assets among our subsidiaries. After adoption of this ASU, the income tax effects associated with these asset transfers, except for the transfer of inventory, will be recognized in the period the asset is transferred versus the current deferral and recognition upon either the sale of the asset to a third party or over the remaining useful life of the asset. We are currently reviewing the requirements of this ASU and evaluating the impact on our consolidated financial statements. We expect to adopt the provisions of ASU 2016-16 on the required adoption date of January 1, 2018. The impact of adopting ASU 2016-16, if any, will be recognized through a cumulative adjustment to accumulated deficit as of the date of adoption. Financial Instruments On June 16, 2016, the FASB issued ASU 2016-13, "Measurement of Credit Losses on Financial Instruments" ("ASU 2016-13"). The primary impact of ASU 2016-13 for us is a change in the model for the recognition of credit losses related to our financial instruments from an incurred loss model, which recognized credit losses only if it was probable that a loss had been incurred, to an expected loss model, which requires our management team to estimate the total credit losses expected on the portfolio of financial instruments. We are currently reviewing the requirements of the standard and evaluating the impact on our consolidated financial statements. We are required to adopt the provisions of ASU 2016-13 effective January 1, 2020, but could elect to early adopt the provisions as of January 1, 2019. We expect to recognize the impacts of adopting ASU 2016-13 through a cumulative adjustment to (accumulated deficit) retained earnings as of the date of adoption. As of the date of this report, we have not yet determined the date we will adopt ASU 2016-13. Leases On February 25, 2016, the FASB issued ASU 2016-02, “Leases” (“ASU 2016-02”). The core principle of ASU 2016-02 will require lessees to present right-of-use assets and lease liabilities on their balance sheets for operating leases, which are currently not reflected on their balance sheets. ASU 2016-02 is effective for annual and interim periods beginning January 1, 2019. Early adoption of ASU 2016-02 is permitted. Upon adoption of ASU 2016-02, we are required to recognize and measure leases at the beginning of the earliest period presented in our consolidated financial statements using a modified retrospective approach. The modified retrospective approach includes a number of optional practical expedients that we may elect to apply. We are currently evaluating new lease administrative and accounting systems and are in the process of developing an implementation plan. We plan to adopt the standard when it becomes effective for us beginning January 1, 2019 and the adoption of the standard will result in the recognition of right of use assets and lease liabilities that have not previously been recorded. Although we believe it is premature as of the date of this report to provide an estimate of the impact of adopting ASU 2016-02, we do expect that it will have a material impact on our consolidated financial statements. Revenue Recognition On May 28, 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers” (“ASU 2014-09”). ASU 2014-09 replaces virtually all existing GAAP on revenue recognition and replaces them with a principles-based approach for determining revenue recognition using a new five step model. The core principle of ASU 2014-09 is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 also includes new accounting principles related to the deferral and amortization of contract acquisition and fulfillment costs. We currently do not defer any contract acquisition costs, but we expect we will defer certain contract acquisition costs in the future, which initially could have the impact of lowering our operating expenses. We currently defer contract fulfillment costs only to the extent of any deferred revenue. Under ASU 2014-09, in certain transactions our deferred contract fulfillment costs could exceed our deferred revenues, which could result in an increase in deferred costs and could also impact the timing on our recognition of these deferred costs. On July 9, 2015, the FASB approved the deferral of the effective date of ASU 2014-09 by one year until January 1, 2018, which is the date we plan to adopt this standard. ASU 2014-09 may be adopted by applying the provisions of this standard on a retrospective basis to the periods included in the financial statements or on a modified retrospective basis, which would result in the recognition of a cumulative effect of adopting ASU 2014-09 in the first quarter of 2018. We have completed our initial assessment of our business and systems requirements, and we are currently developing and implementing a new revenue recognition system to comply with the requirements of ASU 2014-09. In addition, we are undergoing a review of our existing internal controls relating to our revenue recognition and financial reporting processes, and we expect to update or implement additional controls in applying the five-step model for recognizing revenue. We currently plan to adopt the new revenue recognition standard under the modified retrospective transition method. As of the date of this report, we are not able to provide reasonably accurate estimates of the impact of implementing ASU 2014-09 on the timing of our revenue recognition or the transition adjustment that will be recorded to equity on January 1, 2018.
