Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The interim condensed consolidated financial statements of Shenandoah Telecommunications Company and Subsidiaries (collectively, the “Company”) are unaudited. In the opinion of management, all adjustments necessary for a fair presentation of the interim results have been reflected therein. All such adjustments were of a normal and recurring nature. Prior year amounts have been reclassified in some cases to conform to the current year presentation. These financial statements should be read in conjunction with the audited consolidated financial statements and related notes in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016. The accompanying balance sheet information at December 31, 2016 was derived from the audited December 31, 2016 consolidated balance sheet. Operating revenues and income (loss) from operations for any interim period are not necessarily indicative of results that may be expected for the entire year. Management has made an immaterial error correction to the accompanying prior period unaudited condensed consolidated statement of cash flows for the six months ended June 30, 2016 to decrease both the amount of net cash provided by operating activities and the amount of net cash used in investing activities by approximately $10.4 million to properly reflect the common stock issued (non-cash) by the Company to acquire non-controlling interests in a subsidiary of nTelos held by third parties in conjunction with the nTelos acquisition. This immaterial error correction had no effect on the net increase (decrease) in cash and cash equivalents for the period or the beginning or ending balance of cash and cash equivalents for the period. Recently Issued Accounting Standards There have been no developments to recently issued accounting standards, including the expected dates of adoption and estimated effects on the Company's consolidated financial statements and note disclosures, from those disclosed in the Company's 2016 Annual Report on Form 10-K, that would be expected to impact the Company except for the following: In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-09, “Revenue from Contracts with Customers”, which 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 ASU will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. In August 2015, the FASB issued ASU No. 2015-14, delaying the effective date of ASU 2014-09. Three other amendments have been issued during 2016 modifying the original ASU. As amended, the new standard is effective for the Company on January 1, 2018, using either a retrospective basis or a modified retrospective basis with early adoption permitted. The Company plans to adopt the standard effective January 1, 2018. The Company plans to adopt this standard using the modified retrospective transition approach. The Company is continuing to assess all potential impacts of the standard, including the impact to the pattern with which revenue is recognized, the impact of the standard on current accounting policies, practices and system of internal controls, in order to identify material differences, if any that would result from applying the new requirements. In 2016, the Company identified a project team and commenced an initial impact assessment process for ASU 2014-09. The Company is continuing its work toward establishing new policies and processes, and is implementing necessary changes to data and procedures necessary to comply with the new requirements. Based on the results of the project team’s assessment to date, the Company anticipates this standard will have an impact, which could be significant, to the consolidated financial statements. While continuing to assess all potential impacts of the standard, the Company believes the most significant impact relates to additional disclosures required for qualitative and quantitative information concerning the nature, amount, timing, and any uncertainty of revenue and cash flows from contracts with customers, the capitalization of costs of commissions, upfront contract costs, the pattern with which revenue is recognized, and other contract acquisition-based and contract fulfillment costs. In February 2016, the FASB issued ASU No. 2016-02, “Leases”, which requires the recognition of lease assets and lease liabilities by lessees for those leases classified as operating leases under previous generally accepted accounting principles. This change will result in an increase to recorded assets and liabilities on lessees’ financial statements, as well as changes in the categorization of rental costs, from rent expense to interest and depreciation expense. Other effects may occur depending on the types of leases and the specific terms of them utilized by particular lessees. The ASU is effective for us on January 1, 2019, and early application is permitted. Modified retrospective application is required. The Company is currently evaluating the ASU and expects that it will have a material impact on our consolidated financial statements. During the first quarter of 2017, the Company adopted: ASU No. 2015-11, "Inventory: Simplifying the Measurement of Inventory". This ASU changes the measurement principle for inventory from the lower of cost or market to lower of cost and net realizable value. The ASU also eliminates the requirement for entities to consider replacement cost or net realizable value less an approximate normal profit margin when measuring inventory. The adoption of this ASU did not have a significant impact on our financial statements. In March 2017, the FASB issued ASU No. 2017-07, "Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost". The update requires employers to present the service cost component of the net periodic benefit cost in the same income statement line item as other employee compensation costs arising from services rendered during the period. The other components of net benefit cost, including interest cost, expected return on plan assets, amortization of prior service cost/credit and actuarial gain/loss, and settlement and curtailment effects, are to be presented outside of any subtotal of operating income. Employers will have to disclose the line(s) used to present the other components of net periodic benefit cost, if the components are not presented separately in the income statement. ASU 2017-07 is effective for fiscal years and interim periods beginning after December 15, 2017, and early adoption is permitted. The Company is currently assessing the impact that adopting this new accounting standard will have on its consolidated financial statements. The Company does not expect the adoption of ASU 2017-07 to have a material impact on its consolidated financial statements, nor does the Company expect to early adopt ASU 2017-07.
