| Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
| Basis of Presentation | Basis of Presentation Overview. Unless the context requires otherwise, "NII Holdings, Inc.," "NII Holdings," "we," "our," "us" and "the Company" refer to the combined businesses of NII Holdings, Inc. and its consolidated subsidiaries. Our unaudited condensed consolidated financial statements have been prepared under the rules and regulations of the Securities and Exchange Commission, or the SEC. While these financial statements do not include all of the information and footnotes required by accounting principles generally accepted in the United States for complete financial statements, they reflect all adjustments that, in the opinion of management, are necessary for a fair presentation of the results for interim periods. In addition, the year-end condensed consolidated balance sheet data was derived from audited financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States. We refer to our majority-owned Brazilian operating company, Nextel Telecomunicações Ltda., as Nextel Brazil. You should read these condensed consolidated financial statements in conjunction with the consolidated financial statements and notes contained in our annual report on Form 10-K for the year ended December 31, 2017 . You should not expect results of operations for interim periods to be an indication of the results for a full year. Our consolidated results from continuing operations in this quarterly report on Form 10-Q include the results of operations of Nextel Brazil and our corporate headquarters. Sources of Funding. The accompanying consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. As of March 31, 2018, our consolidated sources of funding included $186.5 million in cash and short-term investments, and $110.0 million in cash held in escrow to secure our indemnification obligations in connection with the sale of Nextel Mexico. Based on our business plan, we believe our current sources of funding described above will provide us with sufficient liquidity to fund our business through 2019. Our business plan is based on a number of assumptions, including lower subscriber turnover and a decrease in certain costs compared to 2017. In addition, it assumes that we will recover substantially all of the amount held in escrow in a timely manner. If our actual results of operations differ from our business plan and/or the ultimate amount recovered from our cash held in escrow does not meet our current forecasted amount or is delayed for a significant period of time, our business could be negatively impacted, and we would need to obtain additional funding and/or significantly reduce our planned capital and operational spending to further preserve our liquidity. See Note 5 for more information regarding our recovery of cash held in escrow. Partnership Agreement. On June 5, 2017, we and AINMT Holdings AB, or ice group, an international telecommunications company operating primarily in Norway under the "ice.net" brand, along with certain affiliates of ours and ice group, entered into an investment agreement to partner in the ownership of Nextel Brazil. On July 20, 2017, ice group completed its initial investment of $50.0 million in Nextel Holdings S. à r.l., or Nextel Holdings, a newly formed subsidiary of NII that indirectly owns Nextel Brazil, in exchange for 30% ownership in Nextel Holdings. In connection with the initial investment, ice group received 50.0 million shares of cumulative preferred voting stock in Nextel Holdings, and we received 116.6 million shares of common stock in this entity. The investment agreement also provided ice group with an option, exercisable on or before November 15, 2017, to invest an additional $150.0 million in Nextel Holdings for an additional 30% ownership. ice group did not exercise its option, and on February 27, 2018, we terminated the investment agreement. Since we continue to have a controlling interest in Nextel Brazil, we have consolidated this entity and its subsidiaries. Recently Adopted Accounting Pronouncements. In May 2014, the Financial Accounting Standards Board, or the FASB, issued Accounting Standards Codification, or ASC, No. 2014-09, “Revenue from Contracts with Customers,” or ASC 606, which provides us with a single revenue recognition model for recognizing revenue from contracts with customers and significantly expands the disclosure requirements for revenue arrangements. We implemented ASC 606 on January 1, 2018 using the modified retrospective method. We did not retroactively adjust prior periods. In utilizing the modified retrospective method, we are recognizing the cumulative effect of applying the standard at the date of initial application, and we will continue to disclose the results under both the new and old standards for the remainder of the first year after adoption. See Note 2 for more information surrounding the adoption of ASC 606. In November 2016, the FASB issued ASU No. 2016-18, “Statement of Cash Flows (Topic 230): Restricted Cash,” or ASU 2016-18, which provides guidance regarding cash flow statement classification and presentation of changes in restricted cash. We implemented this new standard on January 1, 2018. As required, we provided a reconciliation of cash and cash equivalents as presented in our condensed consolidated balance sheets to cash, cash equivalents and restricted cash as presented in our condensed consolidated statements of cash flows for all periods presented in Note 4. Reclassifications. We have reclassified some prior period amounts in our condensed consolidated financial statements to conform to our current presentation. |
Revenue Recognition

| Revenue Recognition [Abstract] | |
| Revenue Recognition | Revenue Recognition On January 1, 2018, we implemented ASC 606 using the modified retrospective method. The primary change to our revenue recognition policies relates to contracts with customers where the customer purchases a discounted handset in connection with entering into a contract for telecommunications services. In accordance with ASC 606, we allocate revenue between the handset and the service based on relative standalone selling price, which we refer to as SSP. We recognize revenue when we satisfy a performance obligation by providing services or transferring control of promised handsets and accessories, which are distinct to a customer. We recognize revenue in an amount that reflects the consideration to which we expect to be entitled for those performance obligations. A description of the principal activities from which Nextel Brazil generates its revenue, as well as the associated policies that govern the way in which we recognize these revenues, is as follows: Service and Other Revenues. Nextel Brazil's wireless service revenues primarily consist of access charges for providing customers with voice, data or messaging services over the contract period. We recognize revenue related to access charges ratably over the contract period. The typical length of our service contracts is 12 months for individual customers and 24 months for corporate customers. We elected the practical expedient to record all revenue net of taxes collected from customers, which are subsequently remitted to governmental authorities. Handset and Accessory Revenues. We recognize handset and accessory revenue when a subscriber takes possession of a device. The transaction price of the handset sold, if any, is billed at the time of sale. Although more than 90% of our subscribers typically purchase services only and acquire a handset separately, the remainder of our subscriber base purchases a handset offered at a discounted price bundled with services. In these types of bundled sales, we allocate a portion of our future service billings to the handset and recognize revenue upon handset delivery at the inception of the contract, which results in a contract asset. We determined that contracts with terms longer than one year that involve the sale of both a handset and related services generally do not include a significant financing component. Significant Judgments and Estimates. Nextel Brazil's subscribers generally enter into service contracts with a commitment period in exchange for discounts on handsets and/or service fees. The penalty applied upon early termination of a contract declines over time in proportion to the remaining commitment period. We concluded that the commitment period should be identical to the contract period since, at any point, the early termination penalty is significant relative to the remaining monthly service fees under the contract. In cases where a contract includes both a handset and accessories, for which we recognize handset and accessory revenue at a point in time, and services, for which we recognize revenue ratably over time, judgment is required to determine the SSP for each distinct performance obligation in order to allocate consideration properly. We use a range of amounts to estimate SSP when we sell each of the products and services separately. Remaining Performance Obligations. As of March 31, 2018, we have $360.4 million of remaining performance obligations under open service contracts. For these service contracts, we expect to recognize $341.6 million in operating revenues in the period from April 1, 2018 through March 31, 2019 and $18.8 million thereafter. Contract Assets and Liabilities. Contract assets primarily relate to the remaining portion of Nextel Brazil's future service billings allocated to handsets and recognized into revenue upon handset delivery at the inception of the contract. As of March 31, 2018 and January 1, 2018, Nextel Brazil had $5.7 million and $5.5 million in total contract assets, respectively, $4.5 million of which we classified as a component of prepaid expenses and other in our condensed consolidated balance sheets for both periods. We transfer contract assets to receivables when Nextel Brazil's right to bill becomes unconditional. Contract liabilities primarily relate to upfront fees for wireless services for which the services have not yet been provided. As of March 31, 2018 and January 1, 2018, Nextel Brazil had $3.1 million and $1.7 million in total contract liabilities, respectively, substantially all of which we classified as a component of accrued expenses and other in our condensed consolidated balance sheet. The changes to both the contract asset and contract liability balances during the period, which include opening balances amortized into revenue, were not significant. Cost to Obtain Contracts with Customers. We recognize an asset for the incremental costs of obtaining a contract with a customer. These costs include commissions and related benefits, payroll taxes for sales employees of Nextel Brazil, and commissions payable to our third party distribution channel partners. We amortize these types of costs ratably using the portfolio approach over the estimated customer relationship period, which includes expected future contract renewals. Under the previous accounting standard, we expensed commissions as incurred. As of March 31, 2018 and January 1, 2018, Nextel Brazil had $44.7 million and $42.8 million of deferred costs, respectively, related to expenses required to obtain or fulfill a contract. Of these total deferred costs, as of March 31, 2018 and January 1, 2018, we recorded $17.5 million and $16.3 million , respectively, as a component of prepaid expenses and other and the remaining $27.2 million and $26.5 million , respectively, as a component of other assets in our condensed consolidated balance sheet. In addition, Nextel Brazil recorded $4.1 million in total commissions expense during the three months ended March 31, 2018 as a component of selling, general and administrative expenses in our condensed consolidated statement of comprehensive loss. Adoption Impact. Following is a comparison of our reported results of operations for the three months ended March 31, 2018 compared to amounts that we would have reported had we not adopted ASC 606 (in thousands): As Reported With ASC 606 Without ASC 606 Impact Operating revenues Service and other revenues $ 175,972 $ 180,800 $ (4,828 ) Handset and accessory revenues 5,041 4,685 356 181,013 185,485 (4,472 ) Operating expenses Cost of service (exclusive of depreciation and amortization included below) 88,924 88,924 — Cost of handsets and accessories 9,065 9,065 — Selling, general and administrative 90,886 97,425 (6,539 ) Impairment, restructuring and other (benefits) charges, net (1,825 ) (1,825 ) — Depreciation 4,833 4,833 — Amortization 3,591 3,591 — 195,474 202,013 (6,539 ) Operating loss $ (14,461 ) $ (16,528 ) $ 2,067 Net loss $ (43,320 ) $ (45,387 ) $ 2,067 Components of Transition Adjustment. As of January 1, 2018, the cumulative impact of the implementation of ASC 606 included the recognition of contract assets and liabilities, as well as the capitalization of costs to obtain contracts with customer. In total, these effects resulted in a cumulative adjustment on January 1, 2018 that was comprised of a $21.2 million increase to prepaid expenses and other, a $26.8 million increase to other assets, a $1.1 million increase to accrued expenses and other and a $1.8 million decrease to other long-term liabilities. |

| Restructuring and Related Activities [Abstract] | |
| Impairment, Restructuring and Other (Benefits) Charges | Impairment, Restructuring and Other (Benefits) Charges Long-Lived Asset Impairment. During the first quarter of 2017, we reviewed our Nextel Brazil segment for potential impairment and determined that, as a result of the continued decline in share price, the carrying value of this segment was not fully recoverable. As a result, we recorded a non-cash asset impairment charge of $66.0 million to reduce the carrying values of Nextel Brazil's long-lived assets to their respective fair values. We estimated the fair value of our Nextel Brazil segment using a market approach and allocated these impairment charges on a pro rata basis between property, plant and equipment and spectrum licenses. Restructuring (Benefits) Charges. In an effort to further reduce costs, in the first quarter of 2018, Nextel Brazil entered into arrangements with certain of its tower lessors for the right to exchange approximately 600 unused transmitter and receiver sites for other sites. During the first quarter of 2018, we identified approximately 250 transmitter and receiver sites that we plan to exchange. As a result, Nextel Brazil reversed $13.7 million in previously accrued restructuring charges. In addition, during the three months ended March 31, 2018 and 2017, Nextel Brazil recognized $10.8 million and $3.3 million in restructuring costs, respectively, the majority of which related to future lease costs for approximately 150 iDEN-related transmitter and receiver sites and the separation of approximately 75 employees. Total impairment, restructuring and other (benefits) charges, net for the three months ended March 31, 2018 and 2017 were as follows (in thousands): Three Months Ended March 31, 2018 2017 Brazil $ (2,146 ) $ 71,693 Corporate 321 246 Total impairment, restructuring and other (benefits) charges, net $ (1,825 ) $ 71,939 As of March 31, 2018, total accrued restructuring charges were as follows (in thousands): Balance, January 1, 2018 $ 109,771 Restructuring benefits, net (2,558 ) Cash payments and other (9,979 ) Foreign currency translation adjustment 450 Balance, March 31, 2018 $ 97,684 |

| Supplemental Financial Statement Information | Supplemental Financial Statement Information Restricted Cash. In November 2016, the FASB issued ASU 2016-18, which requires the condensed consolidated statements of cash flows to explain the change in restricted cash and restricted cash equivalents, in addition to the change in cash and cash equivalents as previously required. We adopted this ASU in the first quarter of 2018. As a result of this adoption, the cash and cash equivalents balances in our condensed consolidated statements of cash flows now include restricted cash of $112.6 million as of March 31, 2018, $111.9 million as of December 31, 2017, $165.6 million as of March 31, 2017 and $164.9 million as of December 31, 2016.

Revenue-Based Taxes. Prior to the implementation of ASC 606, we recorded certain revenue-based taxes on a gross basis. For the three months ended March 31, 2017, we recognized $10.1 million in revenue-based taxes as a component of both service and other revenues and selling, general and administrative expenses in our condensed consolidated statement of comprehensive loss. As a result of the adoption of ASC 606, we now record all revenue net of taxes collected from customers. If we had not implemented ASC 606 on January 1, 2018, we would have recognized an additional $4.7 million in revenue-based taxes as a component of service and other revenues in our condensed consolidated statement of comprehensive loss. Diluted Net Loss Per Common Share. As presented for the three months ended March 31, 2018 and 2017, our calculation of diluted net loss from continuing operations per common share is based on the weighted average number of common shares outstanding during those periods and does not include other potential common shares, including shares issuable upon the potential exercise of stock options under our stock-based employee compensation plans or restricted common shares issued under those plans since their effect would have been antidilutive. For the three months ended March 31, 2018, we did not include 3.3 million stock options and 0.1 million restricted common shares in our calculation of diluted net loss from continuing operations per common share because their effect would have been antidilutive. In addition, for the three months ended March 31, 2017, we did not include 3.3 million stock options and 0.5 million restricted common shares in our calculation of diluted net loss from continuing operations per common share because their effect would have been antidilutive. |

| Discontinued Operations | Discontinued Operations Sale of Nextel Mexico. On April 30, 2015, we, together with our wholly-owned subsidiary NIU Holdings LLC, completed the sale of our Mexican operations to New Cingular Wireless, an indirect subsidiary of AT&T. The transaction was structured as a sale of all of the outstanding stock of the parent company of Comunicaciones Nextel de Mexico, S.A. de C.V., or Nextel Mexico, for a purchase price of $1.875 billion , including $187.5 million deposited in escrow to satisfy potential indemnification claims. In 2016, we paid $4.0 million , plus interest, out of escrow to settle an indemnification claim. As of March 31, 2018, $73.5 million of the cash held in escrow has been released to us and $110.0 million remains deposited in escrow related to certain potential tax indemnity claims made by New Cingular Wireless. While we are required to continue to indemnify New Cingular Wireless for any valid claims that arise in the future, New Cingular Wireless is not permitted to make any additional claims against the escrow account. The potential tax indemnity claims submitted by New Cingular Wireless purport to relate to various ongoing tax audits by the Mexican tax authorities for the years 2010 through 2014. Of the total potential tax claims, $12.2 million relates to actual assessments that Nextel Mexico has received. The remaining amounts relate to unassessed matters. New Cingular Wireless' claims include $35.5 million related to the audit of Nextel Mexico’s income tax return for 2010 and $36.9 million related to the audit of Nextel Mexico's income tax return for 2011. The remaining $37.6 million of potential tax claims relates primarily to non-income tax-based audits for the years 2011 through 2014. We recently reached an agreement with the Mexican tax authorities related to the audits of Nextel Mexico's income tax returns for the years 2010 and 2011. Specifically, we agreed to incremental tax liabilities of $36.9 million to settle all open issues related to these tax years. We expect to utilize existing tax credits to settle these liabilities, although it is possible that we may need to settle a portion of these liabilities using cash that is currently held in escrow. We are in the process of working with the Mexican tax authorities to finalize the official process and file the necessary amended income tax returns in an effort to close the audits related to the years 2010 and 2011. As of March 31, 2018, we had $1.5 million accrued related to the 2011 income tax audit. We are continuing to work with the Mexican tax authorities to settle the open non-income tax-based audits and accelerate the release of the remaining escrow. New Cingular Wireless has recently indicated their views on certain aspects of the escrow and purchase agreements related to the release requirements for escrowed funds with which we do not agree. This difference of interpretation could result in a delay of the release of the remaining amount of cash in escrow. There can be no assurance as to the outcome of the foregoing tax audits or indemnity claims. |

In October 2017, Nextel Brazil entered into an amended and restated equipment financing facility and sixth amendments to its two bank loans with Brazilian lenders. In January 2018, we received final approval for the amended and restated equipment financing facility, at which point all of these amendments became effective. We accounted for these amendments as a non-substantial modification of debt and capitalized $6.1 million of financing costs that will be amortized over the new term of the loans. As a result of the amendments, the material financing terms in all three facilities were aligned. Among other changes, loans under these agreements have a 48 -month grace period from January 2018 for material repayments, a 50 -month material repayment term that begins in January 2022 and a final maturity of January 2026 for Nextel Brazil's bank loans and February 2026 for Nextel Brazil's equipment financing facility. These amendments also provide for a holiday for certain financial covenant compliance, including the net debt financial covenant, until June 30, 2020. In connection with these amendments, Nextel Brazil granted additional security interests to each of its lenders in the form of preferential rights to amounts held in certain of Nextel Brazil's bank accounts and pledged incremental equipment and property to these lenders. In addition, Nextel Brazil will be subject to monthly minimum cash and minimum receivable requirements. Nextel Holdings and certain of its subsidiaries have agreed to make equity contributions to Nextel Brazil over the next 48 months. As of March 31, 2018, Nextel Brazil had $244.3 million in principal amount outstanding under its equipment financing facility and $197.9 million in principal amount outstanding under its bank loans. |

| Fair Value Measurements | Fair Value Measurements Financial Instruments. Available-for-Sale Securities. As of March 31, 2018 and December 31, 2017 , available-for-sale securities held by Nextel Brazil included $50.2 million and $16.7 million , respectively, in investment funds. These funds invest primarily in Brazilian government bonds and long-term bank certificates of deposit. During the three months ended March 31, 2018 and 2017, we did not have any material unrealized gains or losses associated with these investments. We account for our available-for-sale securities at fair value. The fair value of Nextel Brazil's investment funds is measured based on the funds' net asset value as a practical expedient, which is excluded from the fair value hierarchy. Debt Instruments. The carrying amounts and estimated fair values of our debt instruments are as follows: March 31, 2018 December 31, 2017 Carrying Amount Estimated Fair Value Carrying Amount Estimated Fair Value (in thousands) Brazil equipment financing $ 243,000 $ 242,418 $ 242,883 $ 237,958 Brazil bank loans and other 193,051 142,480 200,567 144,312 Brazil spectrum financing 121,332 133,593 122,044 128,225 $ 557,383 $ 518,491 $ 565,494 $ 510,495 We estimated the fair value of Nextel Brazil's bank loans, equipment financing and spectrum financing utilizing inputs such as U.S. Treasury security yield curves, prices of comparable bonds, LIBOR, U.S. Treasury bond rates and credit spreads on comparable publicly traded bonds. We consider these fair value measurements to be Level 3 in the fair value hierarchy. Other Financial Instruments. The carrying values of cash and cash equivalents, accounts receivable and accounts payable contained in our condensed consolidated balance sheets approximate their fair values due to the short-term nature of these instruments. |

| Commitments and Contingencies [Abstract] | |
| Contingencies | Contingencies Contingencies. Nextel Brazil has received various assessment notices from municipal, state and federal Brazilian authorities asserting deficiencies in payments related primarily to value-added taxes and other non-income based taxes. Nextel Brazil has filed various administrative and legal petitions disputing these assessments. In some cases, Nextel Brazil has received favorable decisions, which are currently being appealed by the respective governmental authority. In other cases, Nextel Brazil's petitions have been denied, and Nextel Brazil is currently appealing those decisions. As of March 31, 2018 and December 31, 2017, Nextel Brazil also had contingencies related to certain consumer, contract and labor-related matters, some of which are secured by judicial guarantees. Even in cases where there is no probable loss, Nextel Brazil may in the future be subject to litigation involving tax and other matters requiring material judicial deposits of cash that will not be released until the pending matter is resolved. As of March 31, 2018 and December 31, 2017 , Nextel Brazil had accrued liabilities of $94.4 million and $81.2 million , respectively, related to contingencies, of which $8.7 million and $7.4 million related to unasserted claims, respectively. We currently estimate the reasonably possible losses related to matters for which Nextel Brazil has not accrued liabilities, as they are not deemed probable, to be approximately $810.0 million as of March 31, 2018 . We continue to evaluate the likelihood of probable and reasonably possible losses, if any, related to all known contingencies. As a result, future increases or decreases to our accrued liabilities may be necessary and will be recorded in the period when such amounts are determined to be probable and reasonably estimable. Legal Proceedings. We are subject to claims and legal actions that may arise in the ordinary course of business. We do not believe that any of these pending claims or legal actions will have a material effect on our business, financial condition, results of operations or cash flows. |

Valuation allowances are required to be recognized on deferred tax assets unless it is determined that it is “more-likely-than-not” that the asset will be realized. In 2017, w e maintained full valuation allowances on the deferred tax assets of our foreign operating companies, our U.S. parent company and subsidiaries and our foreign holding companies due to substantial negative evidence such as the recent history of cumulative losses and the projected losses for the remainder of 2018 and subsequent years. We maintained this same valuation allowance position through the first quarter of 2018 . |

| Recently Adopted Accounting Pronouncements | Recently Adopted Accounting Pronouncements. In May 2014, the Financial Accounting Standards Board, or the FASB, issued Accounting Standards Codification, or ASC, No. 2014-09, “Revenue from Contracts with Customers,” or ASC 606, which provides us with a single revenue recognition model for recognizing revenue from contracts with customers and significantly expands the disclosure requirements for revenue arrangements. We implemented ASC 606 on January 1, 2018 using the modified retrospective method. We did not retroactively adjust prior periods. In utilizing the modified retrospective method, we are recognizing the cumulative effect of applying the standard at the date of initial application, and we will continue to disclose the results under both the new and old standards for the remainder of the first year after adoption. See Note 2 for more information surrounding the adoption of ASC 606. In November 2016, the FASB issued ASU No. 2016-18, “Statement of Cash Flows (Topic 230): Restricted Cash,” or ASU 2016-18, which provides guidance regarding cash flow statement classification and presentation of changes in restricted cash. We implemented this new standard on January 1, 2018. As required, we provided a reconciliation of cash and cash equivalents as presented in our condensed consolidated balance sheets to cash, cash equivalents and restricted cash as presented in our condensed consolidated statements of cash flows for all periods presented in Note 4. |
| Reclassifications | Reclassifications. We have reclassified some prior period amounts in our condensed consolidated financial statements to conform to our current presentation. |
| Revenue Recognition | Revenue Recognition On January 1, 2018, we implemented ASC 606 using the modified retrospective method. The primary change to our revenue recognition policies relates to contracts with customers where the customer purchases a discounted handset in connection with entering into a contract for telecommunications services. In accordance with ASC 606, we allocate revenue between the handset and the service based on relative standalone selling price, which we refer to as SSP. We recognize revenue when we satisfy a performance obligation by providing services or transferring control of promised handsets and accessories, which are distinct to a customer. We recognize revenue in an amount that reflects the consideration to which we expect to be entitled for those performance obligations. A description of the principal activities from which Nextel Brazil generates its revenue, as well as the associated policies that govern the way in which we recognize these revenues, is as follows: Service and Other Revenues. Nextel Brazil's wireless service revenues primarily consist of access charges for providing customers with voice, data or messaging services over the contract period. We recognize revenue related to access charges ratably over the contract period. The typical length of our service contracts is 12 months for individual customers and 24 months for corporate customers. We elected the practical expedient to record all revenue net of taxes collected from customers, which are subsequently remitted to governmental authorities. Handset and Accessory Revenues. We recognize handset and accessory revenue when a subscriber takes possession of a device. The transaction price of the handset sold, if any, is billed at the time of sale. Although more than 90% of our subscribers typically purchase services only and acquire a handset separately, the remainder of our subscriber base purchases a handset offered at a discounted price bundled with services. In these types of bundled sales, we allocate a portion of our future service billings to the handset and recognize revenue upon handset delivery at the inception of the contract, which results in a contract asset. We determined that contracts with terms longer than one year that involve the sale of both a handset and related services generally do not include a significant financing component. Significant Judgments and Estimates. Nextel Brazil's subscribers generally enter into service contracts with a commitment period in exchange for discounts on handsets and/or service fees. The penalty applied upon early termination of a contract declines over time in proportion to the remaining commitment period. We concluded that the commitment period should be identical to the contract period since, at any point, the early termination penalty is significant relative to the remaining monthly service fees under the contract. In cases where a contract includes both a handset and accessories, for which we recognize handset and accessory revenue at a point in time, and services, for which we recognize revenue ratably over time, judgment is required to determine the SSP for each distinct performance obligation in order to allocate consideration properly. We use a range of amounts to estimate SSP when we sell each of the products and services separately. Remaining Performance Obligations. As of March 31, 2018, we have $360.4 million of remaining performance obligations under open service contracts. For these service contracts, we expect to recognize $341.6 million in operating revenues in the period from April 1, 2018 through March 31, 2019 and $18.8 million thereafter. Contract Assets and Liabilities. Contract assets primarily relate to the remaining portion of Nextel Brazil's future service billings allocated to handsets and recognized into revenue upon handset delivery at the inception of the contract. As of March 31, 2018 and January 1, 2018, Nextel Brazil had $5.7 million and $5.5 million in total contract assets, respectively, $4.5 million of which we classified as a component of prepaid expenses and other in our condensed consolidated balance sheets for both periods. We transfer contract assets to receivables when Nextel Brazil's right to bill becomes unconditional. Contract liabilities primarily relate to upfront fees for wireless services for which the services have not yet been provided. As of March 31, 2018 and January 1, 2018, Nextel Brazil had $3.1 million and $1.7 million in total contract liabilities, respectively, substantially all of which we classified as a component of accrued expenses and other in our condensed consolidated balance sheet. The changes to both the contract asset and contract liability balances during the period, which include opening balances amortized into revenue, were not significant. Cost to Obtain Contracts with Customers. We recognize an asset for the incremental costs of obtaining a contract with a customer. These costs include commissions and related benefits, payroll taxes for sales employees of Nextel Brazil, and commissions payable to our third party distribution channel partners. We amortize these types of costs ratably using the portfolio approach over the estimated customer relationship period, which includes expected future contract renewals. Under the previous accounting standard, we expensed commissions as incurred. As of March 31, 2018 and January 1, 2018, Nextel Brazil had $44.7 million and $42.8 million of deferred costs, respectively, related to expenses required to obtain or fulfill a contract. Of these total deferred costs, as of March 31, 2018 and January 1, 2018, we recorded $17.5 million and $16.3 million , respectively, as a component of prepaid expenses and other and the remaining $27.2 million and $26.5 million , respectively, as a component of other assets in our condensed consolidated balance sheet. In addition, Nextel Brazil recorded $4.1 million in total commissions expense during the three months ended March 31, 2018 as a component of selling, general and administrative expenses in our condensed consolidated statement of comprehensive loss. Adoption Impact. Following is a comparison of our reported results of operations for the three months ended March 31, 2018 compared to amounts that we would have reported had we not adopted ASC 606 (in thousands): As Reported With ASC 606 Without ASC 606 Impact Operating revenues Service and other revenues $ 175,972 $ 180,800 $ (4,828 ) Handset and accessory revenues 5,041 4,685 356 181,013 185,485 (4,472 ) Operating expenses Cost of service (exclusive of depreciation and amortization included below) 88,924 88,924 — Cost of handsets and accessories 9,065 9,065 — Selling, general and administrative 90,886 97,425 (6,539 ) Impairment, restructuring and other (benefits) charges, net (1,825 ) (1,825 ) — Depreciation 4,833 4,833 — Amortization 3,591 3,591 — 195,474 202,013 (6,539 ) Operating loss $ (14,461 ) $ (16,528 ) $ 2,067 Net loss $ (43,320 ) $ (45,387 ) $ 2,067 Components of Transition Adjustment. As of January 1, 2018, the cumulative impact of the implementation of ASC 606 included the recognition of contract assets and liabilities, as well as the capitalization of costs to obtain contracts with customer. In total, these effects resulted in a cumulative adjustment on January 1, 2018 that was comprised of a $21.2 million increase to prepaid expenses and other, a $26.8 million increase to other assets, a $1.1 million increase to accrued expenses and other and a $1.8 million decrease to other long-term liabilities. |
