Accounting Policies [Abstract]
Basis of Presentation and Significant Accounting Policies	BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES Unaudited Interim Financial Statements —The accompanying interim unaudited condensed consolidated financial statements included in this Quarterly Report on Form 10-Q have been prepared by APX Group Holdings, Inc. and subsidiaries (the “Company”) without audit. The accompanying consolidated financial statements include the accounts of APX Group Holdings, Inc. and its subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation. Certain information and footnote disclosures normally included in consolidated financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) have been condensed or omitted pursuant to such rules and regulations. The information as of December 31, 2016 included in the unaudited condensed consolidated balance sheets was derived from the Company’s audited consolidated financial statements. The unaudited condensed consolidated financial statements included in this Quarterly Report on Form 10-Q were prepared on the same basis as the audited consolidated financial statements and, in the opinion of management, reflect all adjustments (all of which are considered of a normal recurring nature) considered necessary to present fairly the Company’s financial position, results of operations and cash flows for the periods and dates presented. The results of operations for the three and nine months ended September 30, 2017 are not necessarily indicative of the results that may be expected for the year ending December 31, 2017 . These unaudited condensed consolidated financial statements and notes should be read in conjunction with the Company’s audited consolidated financial statements and related notes as set forth in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2016 , as filed with the Securities and Exchange Commission (“SEC”) on March 10, 2016, which is available on the SEC’s website at www.sec.gov. Basis of Presentation —The unaudited condensed consolidated financial statements of the Company are presented for APX Group Holdings, Inc. (“Holdings") and its wholly-owned subsidiaries. The Company has prepared the accompanying unaudited condensed consolidated financial statements pursuant to GAAP. Preparing financial statements requires the Company to make estimates and assumptions that affect the amounts that are reported in the consolidated financial statements and accompanying disclosures. Although these estimates are based on the Company’s best knowledge of current events and actions that the Company may undertake in the future, actual results may be different from the Company’s estimates. The results of operations presented herein are not necessarily indicative of the Company’s results for any future period. Vivint Flex Pay —On January 3, 2017, the Company announced the introduction of the Vivint Flex Pay plan (“Vivint Flex Pay”), which became the Company's primary sales model beginning in March 2017. Under Vivint Flex Pay, customers pay separately for the products and related installation (“Products”) and Vivint's smart home and security services (“Services”). The customer has the following three options to pay for the Products: (i) qualified customers in the United States may finance the purchase of Products through a third-party financing provider (“Consumer Financing Program”) (ii) customers not eligible for the Consumer Financing Program, but who qualify under the Company's underwriting criteria, may enter into a retail installment contract (“RIC”) directly with Vivint, or (iii) customers may purchase the Products at the outset of the service contract with cash, ACH, credit or debit card. Although customers pay separately for the Products and Services under the Vivint Flex Pay plan, the Company has determined that the shift in model does not change the Company's conclusion that the Product sales and Services are one combined unit of accounting. As a result, all forms of transactions under Vivint Flex Pay create deferred revenue for the gross amount of Products sold. Gross deferred revenues are reduced by imputed interest on the RICs and the present value of expected payments due to the third-party financing provider under the Consumer Financing Program. These deferred revenues are recognized in a pattern that reflects the estimated life of the subscriber relationships. The Company amortizes these deferred revenues over 15 years using a 240% declining balance method, which converts to a straight-line methodology after approximately nine years when the resulting amortization exceeds that from the accelerated method. Under the Consumer Financing Program, qualified customers are eligible for installment loans provided by a third-party financing provider of up to $4,000 for either 42 or 60 months. The Company pays a monthly fee to the third-party financing provider based on the average daily outstanding balance of the installment loans. Additionally, the Company shares liability for credit losses depending on the credit quality of the customer. Because of the nature of these provisions under the Consumer Financing Program, the Company records a derivative liability at its fair value when the third-party financing provider originates installment loans to customers, which reduces the amount of revenue recognized on the provision of the services. The derivative liability is reduced as payments are made from the Company to the third-party financing provider. Subsequent changes to the fair value of the derivative liability are realized through other loss/(income), net in the Condensed Consolidated Statement of Operations. (See Note 7 ). Retail Installment Contract Receivables — For customers that enter into a RIC under the Vivint Flex Pay plan, the Company records a receivable for the amount financed. The RIC receivables are recorded at their present value, net of the imputed interest. At the time of installation, the Company records a long-term note receivable within long-term investments and other assets, net on the condensed consolidated balance sheets for the present value of the receivables that are expected to be collected beyond 12 months of the reporting date. The unbilled receivable amounts that are expected to be collected within 12 months of the reporting date are included as a short-term notes receivable within accounts and notes receivable, net on the condensed consolidated balance sheets. The billed amounts of notes receivables are included in accounts receivable within accounts and notes receivable, net on the condensed consolidated balance sheets. The Company imputes the interest on the RIC receivable using a risk adjusted market interest rate and records it as an adjustment to deferred revenue and as an adjustment to the face amount of the related receivable. The imputed interest income is recognized over the term of the RIC contract as recurring and other revenue on the condensed consolidated statement of operations. When the Company determines that there are RIC receivables that have become uncollectible, the Company records an allowance for credit losses and bad debt expense. The estimate of allowance for credit losses considers a number of factors, including collection experience, aging of the remaining RIC receivable portfolios, credit quality of the subscriber base and other qualitative considerations, including macro-economic factors. Account balances are written-off if collection efforts are unsuccessful and future collection is unlikely based on the length of time from the day accounts become past due. As of September 30, 2017 and December 31, 2016 there was no allowance for credit losses associated with RIC receivables (See Note 3 ). Accounts Receivable — Accounts receivable consists primarily of amounts due from customers for recurring monthly monitoring services and the billed portion of RIC receivables. The accounts receivable are recorded at invoiced amounts and are non-interest bearing and are included within accounts and notes receivable, net on the condensed consolidated balance sheets. Accounts receivable totaled $20.7 million and $12.9 million at September 30, 2017 and December 31, 2016 , respectively net of the allowance for doubtful accounts of $4.5 million and $4.1 million at September 30, 2017 and December 31, 2016 , respectively. The Company estimates this allowance based on historical collection experience and subscriber attrition rates. When the Company determines that there are accounts receivable that are uncollectible, they are charged off against the allowance for doubtful accounts. As of September 30, 2017 and December 31, 2016 , no accounts receivable were classified as held for sale. The provision for doubtful accounts is included in general and administrative expenses in the accompanying unaudited condensed consolidated statements of operations and totaled $5.0 million and $5.6 million for the three months ended September 30, 2017 and 2016 , respectively. The changes in the Company’s allowance for accounts receivable were as follows for the periods ended (in thousands): Three Months Ended September 30, Nine Months Ended September 30, 2017 2016 2017 2016 Beginning balance $ 3,799 $ 3,097 $ 4,138 $ 3,541 Provision for doubtful accounts 4,997 5,585 14,723 13,302 Write-offs and adjustments (4,316 ) (4,952 ) (14,381 ) (13,113 ) Balance at end of period $ 4,480 $ 3,730 $ 4,480 $ 3,730 Revenue Recognition— The Company recognizes revenue principally on three types of transactions: (i) recurring and other revenue, which includes revenues for monitoring and other smart home services, recognition of deferred revenue associated with the sales of Products at the time of installation, imputed interest associated with the RIC receivables and recurring monthly revenue associated with Vivint Wireless Inc. (“Wireless Internet” or “Wireless”) , (ii) service and other sales, which includes non-recurring service fees charged to subscribers provided on contracts, contract fulfillment revenues and sales of products that are not part of the Company's service offerings, and (iii) activation fees on subscriber contracts, which are amortized over the expected life of the customer. Recurring and other revenue includes (i) the Company’s subscriber contracts associated with Services, which are billed directly to the subscriber in advance, generally monthly, pursuant to the terms of subscriber contracts and recognized ratably over the service period, (ii) monthly recognition of deferred Product revenue and (iii) imputed interest associated with the RIC receivables, which is recognized over the initial term of the RIC. Service and other sales revenue is recognized as services are provided or when title to the products and equipment sold transfers to the customer. Contract fulfillment revenue, included in service and other sales, is recognized when payment is received from customers who cancel their contract in-term. Revenue from sales of products that are not part of the service offering and sold after the initial point of installation is generally recognized upon delivery of products. Activation fees represent upfront one-time charges billed to subscribers at the time of installation and are deferred. The Company amortizes deferred activation fees over 15 years using a 240% declining balance method, which converts to a straight-line methodology after approximately nine years when the resulting amortization exceeds that from the accelerated method. The Company evaluates subscriber account attrition on a periodic basis, utilizing observed attrition rates for the Company’s subscriber contracts and industry information and, when necessary, makes adjustments to the estimated subscriber relationship period and amortization method. Activation fees are no longer charged under Vivint Flex Pay, as these fees will no longer be billed separately to subscribers at the time of installation. Deferred Revenue— The Company's deferred revenues primarily consist of amounts for sales of Products and Services. Deferred Product revenues are recorded at the time of sale and deferred in a pattern that reflects the estimated life of the subscriber relationships. The Company amortizes these deferred revenues over 15 years using a 240% declining balance method, which converts to a straight-line methodology after approximately nine years when the resulting amortization exceeds that from the accelerated method. Deferred Service revenues represent the amounts billed, generally monthly, in advance and collected from customers for services yet to be performed. Subscriber Acquisition Costs — Subscriber acquisition costs represent the costs related to the origination of new subscribers. A portion of subscriber acquisition costs is expensed as incurred, which includes costs associated with the direct-to-home sale housing, marketing and recruiting, certain portions of sales commissions (residuals), overhead and other costs, considered not directly and specifically tied to the origination of a particular subscriber. The remaining portion of the costs is considered to be directly tied to subscriber acquisition and consists primarily of certain portions of sales commissions, equipment and installation costs. These costs are deferred and recognized in a pattern that reflects the estimated life of the subscriber relationships. The Company amortizes subscriber acquisition costs over 15 years using a 240% declining balance method, which converts to a straight-line methodology after approximately nine years when the resulting amortization exceeds that from the accelerated method. The Company evaluates subscriber account attrition on a periodic basis, utilizing observed attrition rates for the Company’s subscriber contracts and industry information and, when necessary, makes adjustments to the estimated subscriber relationship period and amortization method. On the condensed consolidated statement of cash flows, subscriber acquisition costs that are comprised of equipment and related installation costs purchased for or used in subscriber contracts in which the Company retains ownership to the equipment are classified as investing activities and reported as “Subscriber acquisition costs – company owned equipment”. All other subscriber acquisition costs are classified as operating activities and reported as “Subscriber acquisition costs – deferred contract costs” on the condensed consolidated statements of cash flows as these assets represent deferred costs associated with customer contracts. Cash and Cash Equivalents— Cash and cash equivalents consists of highly liquid investments with remaining maturities when purchased of three months or less. Inventories —Inventories, which are comprised of smart home and security system equipment and parts, are stated at the lower of cost or net realizable value with cost determined under the first-in, first-out (FIFO) method. The Company adjusts the inventory balance based on anticipated obsolescence, usage and historical write-offs. Long-lived Assets and Intangibles — Property, plant and equipment are stated at cost and depreciated on the straight-line method over the estimated useful lives of the assets or the lease term for assets under capital leases, whichever is shorter. Intangible assets with definite lives are amortized over the remaining estimated economic life of the underlying technology or relationships, which ranges from five to ten years . Definite-lived intangible assets are amortized on the straight-line method over the estimated useful life of the asset or in a pattern in which the economic benefits of the intangible asset are consumed. Amortization expense associated with leased assets is included with depreciation expense. Routine repairs and maintenance are charged to expense as incurred. The Company periodically assesses potential impairment of its long-lived assets and intangibles and performs an impairment review whenever events or changes in circumstances indicate that the carrying value may not be recoverable. In addition, the Company periodically assesses whether events or changes in circumstance continue to support an indefinite life of certain intangible assets or warrant a revision to the estimated useful life of definite-lived intangible assets. Wireless Spectrum Licenses —The Company has capitalized, as an intangible asset, wireless spectrum licenses that its subsidiary acquired from a third party. The cost basis of the wireless spectrum asset includes the purchase price paid for the licenses at the time of acquisition, plus costs incurred to acquire the licenses. The asset and related liability were recorded at the net present value of future cash outflows using the Company's incremental borrowing rate at the time of acquisition. The Company has determined that the wireless spectrum licenses meet the definition of indefinite-lived intangible assets because the licenses may be renewed periodically for a nominal fee, provided that the Company continues to meet the service and geographic coverage provisions. The Company has also determined that there are currently no legal, regulatory, contractual, competitive, economic or other factors that limit the useful lives of these wireless spectrum licenses. Long-term Investments —The Company’s long-term investments are comprised of available-for-sale securities and cost-based investments in other companies. As of September 30, 2017 and December 31, 2016 , cost-based investments totaled $0.6 million and $0.4 million and available-for-sale securities totaled $3.7 million and $4.0 million , respectively. The Company’s marketable equity securities have been classified and accounted for as available-for-sale. Management determines the appropriate classification of its investments at the time of purchase and reevaluates the classifications at each balance sheet date. Marketable equity securities, are classified as either short-term or long-term, based on the nature of each security and its availability for use in current operations. The Company’s marketable equity securities are carried at fair value, with unrealized gains and losses, reported as a component of accumulated other comprehensive income (“AOCI”) in equity, with the exception of unrealized losses believed to be other-than-temporary which are reported in earnings in the current period. The cost of securities sold is based upon the specific identification method. The Company performs impairment analyses of its cost based investments when events occur or circumstances change that would, more likely than not, reduce the fair value of the investment below its carrying value. When indicators of impairment do not exist and certain accounting criteria are met, the Company evaluates impairment using a qualitative approach. As of September 30, 2017 and December 31, 2016 , no indicators of impairment existed associated with these cost based investments. Deferred Financing Costs —Costs incurred in connection with obtaining debt financing are deferred and amortized utilizing the straight-line method, which approximates the effective-interest method, over the life of the related financing. Deferred financing costs incurred with draw downs on APX Group, Inc.’s (“APX”) revolving credit facility will be amortized over the amended maturity dates discussed in Note 2 . If such financing is paid off or replaced prior to maturity with debt instruments that have substantially different terms, the unamortized costs are charged to expense. Deferred financing costs included in the accompanying unaudited condensed consolidated balance sheets within deferred financing costs, net at September 30, 2017 and December 31, 2016 were $3.4 million and $4.4 million , net of accumulated amortization of $8.3 million and $6.9 million , respectively. Deferred financing costs included in the accompanying unaudited condensed consolidated balance sheets within notes payable, net at September 30, 2017 and December 31, 2016 were $38.1 million and $39.4 million , net of accumulated amortization of $42.8 million and $35.6 million , respectively. Amortization expense on deferred financing costs recognized and included in interest expense in the accompanying unaudited condensed consolidated statements of operations, totaled $2.8 million and $2.9 million for the three months ended September 30, 2017 and 2016 , respectively and $8.7 million and $8.6 million for the nine months ended September 30, 2017 and 2016 (See Note 2 ). Residual Income Plan —The Company has a program that allows certain third-party sales channel partners to receive additional compensation based on the performance of the underlying contracts they create. The Company calculates the present value of the expected future payments and recognizes this amount in the period the commissions are earned. Subsequent accretion and adjustments to the estimated liability are recorded as interest and operating expense, respectively. The Company monitors actual payments and customer attrition on a periodic basis and, when necessary, makes adjustments to the liability. The amount included in accrued payroll and commissions was $2.2 million and $1.2 million at September 30, 2017 and December 31, 2016 , respectively, and the amount included in other long-term obligations was $11.6 and $6.6 million at September 30, 2017 and December 31, 2016 , respectively, representing the present value of the estimated amounts owed to third-party sales channel partners. Stock-Based Compensation —The Company measures compensation costs based on the grant-date fair value of the award and recognizes that cost over the requisite service period of the awards (See Note 9 ). During the first quarter of 2017, the Company adopted Accounting Standard Update (“ASU”) 2016-09. Under the provisions of ASU 2016-09, the Company has elected to recognize the impact of forfeitures when they occur with no adjustment for estimated forfeitures and recognizes excess tax benefits as a reduction of income tax expense regardless of whether the benefit reduces income taxes payable. Additionally, the Company recognizes the cash flow impact of such excess tax benefits in operating activities in the condensed consolidated statements of cash flows. The Company adopted ASU 2016-09 on a modified retrospective basis for the income statement impact of forfeitures and income taxes and have retrospectively applied ASU 2016-09 to its condensed consolidated statements of cash flows for the impact of excess tax benefits. Accordingly, the Company recognized an immaterial cumulative adjustment charge for the adoption of the impact of forfeitures to beginning retained earnings as of January 1, 2017. The Company recognized no cumulative adjustment benefit for the excess tax benefit for the exercise of equity grants from prior fiscal years due to a full valuation allowance recorded against the excess tax benefits. Advertising Expense —Advertising costs are expensed as incurred. Advertising costs were $12.6 million and $8.4 million for the three months ended September 30, 2017 and 2016 , respectively and $33.7 million and $25.4 million for the nine months ended September 30, 2017 and 2016 . Income Taxes —The Company accounts for income taxes based on the asset and liability method. Under the asset and liability method, deferred tax assets and deferred tax liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Valuation allowances are established when necessary to reduce deferred tax assets when it is determined that it is more likely than not that some portion of the deferred tax asset will not be realized. The Company recognizes the effect of an uncertain income tax position on the income tax return at the largest amount that is more-likely-than-not to be sustained upon audit by the relevant taxing authority. An uncertain income tax position will not be recognized if it has less than a 50% likelihood of being sustained. The Company’s policy for recording interest and penalties is to record such items as a component of the provision for income taxes. Concentrations of Credit Risk —Financial instruments that potentially subject the Company to concentration of credit risk consist principally of receivables and cash. At times during the year, the Company maintains cash balances in excess of insured limits. The Company is not dependent on any single customer or geographic location. The loss of a customer would not adversely impact the Company’s operating results or financial position. Concentrations of Supply Risk —As of September 30, 2017 , approximately 68% of the Company’s installed panels were SkyControl panels and 30% were 2GIG Go!Control panels. In connection with the 2GIG Sale in April 2013, the Company entered into a five -year supply agreement with 2GIG, pursuant to which they will be the exclusive provider of the Company’s control panel requirements, subject to certain exceptions as provided in the supply agreement. The loss of 2GIG as a supplier could potentially impact the Company’s operating results or financial position. Fair Value Measurement —Fair value is based on the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Assets and liabilities subject to on-going fair value measurement are categorized and disclosed into one of three categories depending on observable or unobservable inputs employed in the measurement. These two types of inputs have created the following fair value hierarchy: Level 1: Quoted prices in active markets that are accessible at the measurement date for assets and liabilities. Level 2: Observable prices that are based on inputs not quoted in active markets, but corroborated by market data. Level 3: Unobservable inputs are used when little or no market data is available. This hierarchy requires the Company to minimize the use of unobservable inputs and to use observable market data, if available, when determining fair value. The Company recognizes transfers between levels of the hierarchy based on the fair values of the respective financial measurements at the end of the reporting period in which the transfer occurred. There were no transfers between levels of the fair value hierarchy during the nine months ended September 30, 2017 and 2016 . The carrying amounts of the Company’s accounts receivable, accounts payable and accrued and other liabilities approximate their fair values due to their short maturities. Goodwill —The Company conducts a goodwill impairment analysis annually in the fourth fiscal quarter, as of October 1, and as necessary if changes in facts and circumstances indicate that the fair value of the Company’s reporting units may be less than its carrying amount. When indicators of impairment do not exist and certain accounting criteria are met, the Company is able to evaluate goodwill impairment using a qualitative approach. When necessary, the Company’s quantitative goodwill impairment test consists of two steps. The first step requires that the Company compare the estimated fair value of its reporting units to the carrying value of the reporting unit’s net assets, including goodwill. If the fair value of the reporting unit is greater than the carrying value of its net assets, goodwill is not considered to be impaired and no further testing is required. If the fair value of the reporting unit is less than the carrying value of its net assets, the Company would be required to complete the second step of the test by analyzing the fair value of its goodwill. If the carrying value of the goodwill exceeds its fair value, an impairment charge is recorded. As of September 30, 2017 , there were no changes in facts and circumstances since the most recent annual impairment analysis to indicate impairment existed. Foreign Currency Translation and Other Comprehensive Income —The functional currencies of Vivint Canada, Inc. and Vivint New Zealand, Ltd. are the Canadian and New Zealand dollars, respectively. Accordingly, assets and liabilities are translated from their respective functional currencies into U.S. dollars at period-end rates and revenue and expenses are translated at the weighted-average exchange rates for the period. Adjustments resulting from this translation process are classified as other comprehensive income (loss) and shown as a separate component of equity. During the three months ended September 30, 2016, the Company sold all of its New Zealand and Puerto Rico subscriber contracts and ceased operations in these geographical regions (“2016 Contract Sales”). See Note 13 for further information on the 2016 Contract Sales. When intercompany foreign currency transactions between entities included in the consolidated financial statements are of a long term investment nature (i.e., those for which settlement is not planned or anticipated in the foreseeable future) foreign currency translation adjustments resulting from those transactions are included in stockholders’ deficit as accumulated other comprehensive loss. When intercompany transactions are deemed to be of a short term nature, translation adjustments are required to be included in the condensed consolidated statement of operations. Beginning in July 2015, the Company determined that settlement of Vivint Canada, Inc. and Vivint New Zealand, Ltd. intercompany balances was anticipated and therefore such balances were deemed to be of a short term nature. Translation activity included in the statement of operations in other loss, net related to intercompany balances was a gain of $3.1 million for the three months ended September 30, 2017 and a loss of $0.8 million for the three months ended September 30, 2016 . Translation gains included in the statement of operations in other loss, net related to intercompany balances were $5.5 million and $4.1 million for the nine months ended September 30, 2017 and 2016 , respectively. Letters of Credit —As of September 30, 2017 and December 31, 2016 , the Company had $8.7 million and $5.7 million , respectively, of letters of credit issued in the ordinary course of business, all of which are undrawn. Restructuring and Asset Impairment Charges —Restructuring and asset impairment charges represent expenses incurred in relation to activities to exit or dispose of portions of the Company's business that do not qualify as discontinued operations. Liabilities associated with restructuring are measured at their fair value when the liability is incurred. Expenses for related termination benefits are recognized at the date the Company notifies the employee, unless the employee must provide future service, in which case the benefits are expensed ratably over the future service period. Liabilities related to termination of a contract are measured and recognized at fair value when the contract does not have any future economic benefit to the entity and the fair value of the liability is determined based on the present value of the remaining obligation. The Company expenses all other costs related to an exit or disposal activity as incurred (See Note 13 ). New Accounting Pronouncements —In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers (Topic 606),” which supersedes the revenue recognition requirements in “Revenue Recognition (Topic 605).” Under Topic 606, revenue is recognized when a customer obtains control of promised goods or services and is recognized in an amount that reflects the consideration which the entity expects to receive in exchange for those goods or services. In addition, Topic 606 requires enhanced disclosures, including disclosure of the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. The FASB has recently issued several amendments to the standard, including clarification on accounting for licenses of intellectual property and identifying performance obligations. Topic 606 will be effective for the Company beginning with the first quarter of fiscal 2018. The Company offers its customers a smart home service combining its proprietary control panel; equipment in the home that interfaces with the control panel, including door and window sensors, door locks, security cameras and smoke alarms (“Interfacing Equipment”); installation; and its proprietary back end cloud platform software and services. These combined elements together create

Debt Disclosure [Abstract]
Long-Term Debt	LONG-TERM DEBT Notes Payable On November 16, 2012, APX issued $1.3 billion aggregate principal amount of notes, of which $925.0 million aggregate principal amount of 6.375% senior secured notes due 2019 (the “2019 notes”) mature on December 1, 2019 and are secured on a first-priority lien basis by substantially all of the tangible and intangible assets whether now owned or hereafter acquired by the Company, subject to permitted liens and exceptions, and $380.0 million aggregate principal amount of 8.75% senior notes due 2020 (the “2020 notes”), mature on December 1, 2020. During 2013, APX completed two offerings of additional 2020 notes under the indenture dated November 16, 2012. On May 31, 2013, the Company issued $200.0 million of 2020 notes at a price of 101.75% and on December 13, 2013, APX issued an additional $250.0 million of 2020 notes at a price of 101.50% . During 2014, APX issued an additional $100.0 million of 2020 notes at a price of 102.00% . In October 2015, APX issued $300.0 million aggregate principal amount of 8.875% senior secured notes due 2022 (the “2022 private placement notes”), pursuant to a note purchase agreement dated as of October 19, 2015 in a private placement exempt from registration under the Securities Act. The 2022 private placement notes will mature on December 1, 2022, unless on September 1, 2020 (the 91st day prior to the maturity of the 2020 notes) more than an aggregate principal amount of $190.0 million of such 2020 notes remain outstanding or have not been refinanced as permitted under the note purchase agreement for the 2022 private placement notes, in which case the 2022 private placement notes will mature on September 1, 2020. The 2022 private placement notes are secured, on a pari passu basis, by the collateral securing obligations under the 2019 notes, the 2022 private placement notes, the 2022 notes (as defined below), and the 2023 notes (as defined below) and the revolving credit facilities, in each case, subject to certain exceptions and permitted liens. In May 2016, APX issued $500.0 million aggregate principal amount of 7.875% senior secured notes due 2022 (the “2022 notes”), pursuant to an indenture dated as of May 26, 2016 among APX, the guarantors party thereto and Wilmington Trust, National Association, as trustee and collateral agent (“May 2016 issuance”.) The 2022 notes will mature on December 1, 2022, or on such earlier date when any outstanding pari passu lien indebtedness matures as a result of the operation of any “Springing Maturity” provision set forth in the agreements governing such pari passu lien indebtedness. The 2022 notes are secured, on a pari passu basis, by the collateral securing obligations under the 2019 notes and 2022 private placement notes and the revolving credit facilities, in all cases, subject to certain exceptions and permitted liens. APX used a portion of the net proceeds from the issuance of the 2022 notes to repurchase approximately $235 million aggregate principal amount of the outstanding 2019 notes and 2022 private placement notes in privately negotiated transactions and repaid borrowings under the existing revolving credit facility. In August 2016, APX issued an additional $100.0 million aggregate principal amount of the 2022 notes at a price of 104.00% . In February 2017, APX issued an additional $300.0 million aggregate principal amount of the 2022 notes at a price of 108.25% (“February 2017 issuance”.) A portion of the net proceeds from the offering of these 2022 notes were used to redeem $300.0 million aggregate principal amount of the existing 2019 notes and pay the related accrued interest and redemption premium, and to pay all fees and expenses related thereto and any remaining proceeds will be used for general corporate purposes. In August 2017, APX issued $400.0 million aggregate principal amount of the 7.625% senior notes due 2023 (the “2023 notes” and, together with the 2019 notes, the 2020 notes and the 2022 private placement notes, the “notes”) (“August 2017 issuance”.) The proceeds from the outstanding 2023 notes offering were used to redeem $150.0 million aggregate principal amount of the outstanding 2019 notes and pay the related accrued interest and redemption premium, and to pay all fees and expenses related thereto. Any remaining net proceeds have been or will be used for general corporate purposes, which may include the repayment of outstanding borrowings under the revolving credit facility. The notes are fully and unconditionally guaranteed, jointly and severally by APX and each of APX’s existing restricted subsidiaries that guarantee indebtedness under APX’s revolving credit facility or our other indebtedness. Interest accrues at the rate of 6.375% per annum for the 2019 notes, 8.75% per annum for the 2020 notes, 8.875% per annum for the 2022 private placement notes, and 7.875% per annum for the 2022 notes. Interest on the notes is payable semiannually in arrears on each June 1 and December 1. APX may redeem the notes at the prices and on the terms specified in the applicable indenture or note purchase agreement. Debt Modifications and Extinguishments In accordance with ASC 470-50 Debt – Modifications and Extinguishments, the Company performed analyses on a creditor-by-creditor basis for the May 2016 issuance, February 2017 issuance and August 2017 issuance to determine if the repurchased notes were substantially different than the notes issued to determine the appropriate accounting treatment of associated issuance fees. As a result of these analyses the company recorded the following amounts of other expense and loss on extinguishment and deferred financing costs during the three and nine months ended September 30, 2017 and 2016 (in thousands): Other expense and loss on extinguishment Deferred financing costs Issuance Original discount extinguished Original deferred financing costs extinguished New financing costs Total other expense and loss on extinguishment Original deferred financing rolled over New deferred financing costs Total deferred financing costs Three months ended September 30, 2017 August 2017 issuance $ — $ 1,408 $ 8,881 $ 10,289 $ 473 $ 4,556 $ 5,029 Nine months ended September 30, 2017 August 2017 issuance — 1,408 8,881 10,289 473 4,556 5,029 February 2017 issuance — 3,259 9,491 12,750 1,476 6,077 7,553 Nine months ended September 30, 2016 May 2016 issuance 355 695 9,036 10,086 3,423 6,628 10,051 The original unamortized portion of deferred financing costs associated with new creditors and creditors under the repurchased notes, whose debt instruments were not deemed to be substantially different, will be amortized to interest expense over the life of the issued notes. The Company had no debt issuances or related modification or extinguishment costs during the three months ended September 30, 2016. The following table presents deferred financing cost activity for the nine months ended September 30, 2017 (in thousands): Unamortized Deferred Financing Costs Balance December 31, 2016 Additions Rolled Over Early Extinguishment Amortized Balance September 30, 2017 Revolving Credit Facility $ 4,420 $ 399 $ — $ — $ (1,446 ) $ 3,373 2019 Notes 11,693 — (1,949 ) (4,667 ) (1,824 ) 3,253 2020 Notes 15,053 — — — (2,884 ) 12,169 2022 Private Placement Notes 903 — — — (113 ) 790 2022 Notes 11,714 6,077 1,476 — (2,383 ) 16,884 2023 Notes — 4,556 473 — (70 ) 4,959 Total Deferred Financing Costs $ 43,783 $ 11,032 $ — $ (4,667 ) $ (8,720 ) $ 41,428 Revolving Credit Facility On November 16, 2012, APX entered into a $200.0 million senior secured revolving credit facility, with a five year maturity. On March 6, 2015, APX amended and restated the credit agreement governing the revolving credit facility to provide for, among other things, (1) an increase in the aggregate commitments previously available to APX thereunder from $200.0 million to $289.4 million (“Revolving Commitments”) and (2) the extension of the maturity date with respect to certain of the previously available commitments. On August 10, 2017, APX further amended and restated the credit agreement governing the revolving credit facility to provide for, among other things, (1) an increase in the aggregate commitments previously available to us from $289.4 million to $324.3 million and (2) the extension of the maturity date with respect to certain of the previously available commitments. Borrowings under the amended and restated revolving credit facility bear interest at a rate per annum equal to an applicable margin plus, at APX’s option, either (1) the base rate determined by reference to the highest of (a) the Federal Funds rate plus 0.50% , (b) the prime rate of Bank of America, N.A. and (c) the LIBOR rate determined by reference to the costs of funds for U.S. dollar deposits for an interest period of one month, plus 1.00% or (2) the LIBOR rate determined by reference to the London interbank offered rate for dollars for the interest period relevant to such borrowing. The applicable margin for base rate-based borrowings (1)(a) under the Series A Revolving Commitments of approximately $267.0 million , Series C Revolving Commitments of approximately $20.8 million and Series D Revolving Commitments of approximately $15.4 million is currently 2.0% per annum and (b) under the Series B Revolving Commitments of approximately $21.2 million is currently 3.0% and (2)(a) the applicable margin for LIBOR rate-based borrowings (a) under the Series A Revolving Commitments, Series C Revolving Commitments, and Series D Revolving Commitments is currently 3.0% per annum and (b) under the Series B Revolving Commitments is currently 4.0% . The applicable margin for borrowings under the revolving credit facility is subject to one step-down of 25 basis points based on APX meeting a consolidated first lien net leverage ratio test at the end of each fiscal quarter. Outstanding borrowings under the amended and restated revolving credit facility are allocated on a pro-rata basis between each Series based on the total Revolving Commitments. In addition to paying interest on outstanding principal under the revolving credit facility, APX is required to pay a quarterly commitment fee (which will be subject to one interest rate step-down of 12.5 basis points, based on APX meeting a consolidated first lien net leverage ratio test) to the lenders under the revolving credit facility in respect of the unutilized commitments thereunder. APX also pays customary letter of credit and agency fees. APX is not required to make any scheduled amortization payments under the revolving credit facility. The principal amount outstanding under the revolving credit facility will be due and payable in full on (1) with respect to the non-extended commitments under the Series C Revolving Credit Facility, November 16, 2017 , (2) with respect to the non-extended commitments under the Series D, March 31, 2019 and (3) with respect to the extended commitments under the Series A Revolving Credit Facility and Series B Revolving Credit Facility, March 31, 2021 .

Depreciation and amortization expense on all property, plant and equipment was $5.2 million and $4.2 million for the three months ended September 30, 2017 and 2016 , respectively and $14.9 million and $12.4 million for the nine months ended September 30, 2017 and 2016 , respectively. Amortization expense relates to assets under capital leases and is included in depreciation and amortization expense. In June 2016, the Company entered into a non-cancellable lease to occupy a new building constructed in Logan, UT as a location to further sales recruitment and training, as well as conduct research and development (the "Logan Facility"). Because of its involvement in certain aspects of the construction of the Logan Facility, per the terms of the lease, the Company was deemed the owner of the building for accounting purposes during the construction period. Accordingly, the Company recorded a build-to-suit lease asset and a corresponding build-to-suit lease liability during the construction period. In April 2017, construction on the Logan Facility was completed and the Company commenced occupancy. In accordance with ASC 840-40 Sale-Leaseback Transactions, the building did not qualify for sale-leaseback treatment. As such, the Company will retain the building asset and corresponding lease obligation on the balance sheet. Accordingly, the Company has a build-to-suit building asset, which totaled $8.2 million and $5.0 million , respectively, net of accumulated depreciation of $0.3 million and $0 as of September 30, 2017 and December 31, 2016 , respectively.

The lease term is for seven years, with an option to become the licensor of record with the Federal Communications Commission ("FCC") with respect to the applicable spectrum licenses at the end of this term for a nominal fee. The Company acquired $31.3 million of spectrum licenses, measured using the present value of the lease payments, and recorded an intangible asset and a corresponding liability within other long-term obligations. While licenses are issued for only a fixed time, such licenses are subject to renewal by the FCC. The Company intends to renew the licenses with the FCC at the end of the initial term. License renewals within the industry have occurred routinely and at nominal cost. Moreover, the Company has determined that there are currently no legal, regulatory, contractual, competitive, economic or other factors that limit the useful life of the licenses. As a result, the Company treats the wireless licenses as an indefinite-lived intangible asset. Amortization expense related to intangible assets was approximately $25.5 million and $29.3 million for the three months ended September 30, 2017 and 2016 , respectively and $76.3 million and $87.7 million during the nine months ended September 30, 2017 and 2016 , respectively. As of September 30, 2017 , the remaining weighted-average amortization period for definite-lived intangible assets was 5.1 years.

On October 28, 2016 the investee began trading shares publicly and the Company's preferred stock was converted to publicly traded common stock. As a result, the Company classified the investment as an available for sale security.

Derivative Financial Instruments Under the Consumer Financing Program, the Company pays a monthly fee to a third-party financing provider based on the average daily outstanding balance of the installment loans and shares the liability for credit losses, depending on the credit quality of the customer. Because of the nature of certain provisions under the Consumer Financing Program, the Company records a derivative liability that is not designated as a hedging instrument and is adjusted to fair value, measured using the present value of the estimated future payments. Changes to the fair value are recorded through other loss (income), net in the Condensed Consolidated Statement of Operations. The following represent the contractual obligations with the third-party financing provider under the Consumer Financing Program that are components of the derivative: • The Company pays a monthly fee based on the average daily outstanding balance of the installment loans • The Company shares the liability for credit losses depending on the credit quality of the customer • The Company pays transactional fees associated with customer payment processing During the three and nine months ended September 30, 2017 , the Company recognized a loss on its derivative instrument of $1.4 million .

Income Taxes

Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES In order to determine the quarterly provision for income taxes, the Company uses an estimated annual effective tax rate, which is based on expected annual income and statutory tax rates in the various jurisdictions in which the Company operates. Certain significant or unusual items are separately recognized in the quarter during which they occur and can be a source of variability in the effective tax rates from quarter to quarter. The Company’s effective income tax rate for the nine months ended September 30, 2017 and 2016 was approximately a negative 0.85% and a negative 0.27% , respectively. Income tax expense for the nine months ended September 30, 2017 was affected by an intraperiod tax allocation due to unrealized gains and losses on investments held by the Company and prior year return-to-provision true up adjustments on the U.S. and Canadian tax returns. Both the 2017 and 2016 effective tax rates are less than the statutory rate primarily due to the combination of not benefiting from expected pre-tax US losses and recognizing current state income tax expense for minimum state taxes. Significant judgment is required in determining the Company’s provision for income taxes, recording valuation allowances against deferred tax assets and evaluating the Company’s uncertain tax positions. In evaluating the ability to realize its deferred tax assets, in full or in part, the Company considers all available positive and negative evidence, including past operating results, forecasted future earnings, and prudent and feasible tax planning strategies. Due to historical net losses incurred and the uncertainty of realizing the deferred tax assets, for all the periods presented, the Company has maintained a full valuation allowance against domestic deferred tax assets. The Company has not recorded a valuation allowance against its foreign deferred tax assets due to being in a net deferred tax liability position. During the first quarter of 2017, the Company adopted ASU 2016-09. Under the provisions of ASU 2016-09, the Company recognizes the impact of stock-based compensation award forfeitures when they occur with no adjustment for estimated forfeitures and recognizes excess tax benefits as a reduction of income tax expense regardless of whether the benefit reduces income taxes payable. The Company recognized no cumulative adjustment benefit for the excess tax benefit for the exercise of equity grants from prior fiscal years due to a full valuation allowance recorded against the excess tax benefits.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock-Based Compensation and Equity	STOCK-BASED COMPENSATION AND EQUITY 313 Incentive Units The Company’s indirect parent, 313 Acquisition LLC (“313”), which is majority owned by Blackstone, has authorized the award of profits interests, representing the right to share a portion of the value appreciation on the initial capital contributions to 313 (“Incentive Units”). In March 2015, a total of 4,315,106 Incentive Units previously issued to the Company’s Chief Executive Officer and President were voluntarily relinquished. The Company recorded all unrecognized stock-based compensation associated with such Incentive Units at the time the Incentive Units were relinquished. As of September 30, 2017 , 85,812,836 Incentive Units had been awarded, and were outstanding, to current and former members of senior management and a board member, of which 42,169,456 were outstanding to the Company’s Chief Executive Officer and President. The Incentive Units are subject to time-based and performance-based vesting conditions, with one-third subject to ratable time-based vesting over a five year period and two-thirds subject to the achievement of certain investment return thresholds by The Blackstone Group, L.P. and its affiliates (“Blackstone”). The Company has not recorded any expense related to the performance-based portion of the awards, as the achievement of the vesting condition is not yet deemed probable. The fair value of stock-based awards is measured at the grant date and is recognized as expense over the employee’s requisite service period. The grant date fair value was primarily determined using a Monte Carlo simulation valuation approach with the following assumptions: expected volatility varies from 55% to 125% ; expected exercise term between 3.96 and 6.00 years ; and risk-free rates between 0.62% and 1.18% . Vivint Stock Appreciation Rights The Company’s subsidiary, Vivint Group, Inc. (“Vivint Group”), has awarded Stock Appreciation Rights (“SARs”) to various levels of key employees, pursuant to an omnibus incentive plan. The purpose of the SARs is to attract and retain personnel and provide an opportunity to acquire an equity interest of Vivint Group. The SARs are subject to time-based and performance-based vesting conditions, with one-third subject to ratable time-based vesting over a five year period and two-thirds subject to the achievement of certain investment return thresholds by 313. The Company has not recorded any expense related to the performance-based portion of the awards, as the achievement of the vesting condition is not yet deemed probable. In connection with this plan, 24,244,659 SARs were outstanding as of September 30, 2017 . In addition, 53,621,891 SARs have been set aside for funding incentive compensation pools pursuant to long-term incentive plans established by the Company. On April 1, 2015, a new plan was created and all issued and outstanding Vivint, Inc. (“Vivint”) SARs were re-granted and all reserved SARs were converted under the new Vivint Group plan. The Company assessed the conversion of the SARs as a modification of equity instruments. The restructuring did not change the fair value of the existing awards and as such, no incremental compensation expense was incurred as a result of the restructuring. The fair value of the Vivint Group awards is measured at the grant date and is recognized as expense over the employee’s requisite service period. The fair value is determined using a Black-Scholes option valuation model with the following assumptions: expected volatility varies from 55% to 125% , expected dividends of 0% ; expected exercise term between 6.00 and 6.47 years ; and risk-free rates between 0.61% and 1.77% . Due to the lack of historical exercise data, the Company used the simplified method in determining the estimated exercise term, for all Vivint Group awards. Wireless Stock Appreciation Rights The Company’s subsidiary, Vivint Wireless, has awarded SARs to various key employees, pursuant to an omnibus incentive plan. The purpose of the SARs is to attract and retain personnel and provide an opportunity to acquire an equity interest of Vivint Wireless. The SARs are subject to a five year time-based ratable vesting period. In connection with this plan, 10,000 SARs were outstanding as of September 30, 2017 . The Company does not intend to issue any additional Wireless SARs. The fair value of the Vivint Wireless awards is measured at the grant date and is recognized as expense over the employee’s requisite service period. The fair value is determined using a Black-Scholes option valuation model with the following assumptions: expected volatility of 65% , expected dividends of 0% ; expected exercise term between 6.00 and 6.50 years ; and risk-free rates between 1.51% and 1.77% . Due to the lack of historical exercise data, the Company used the simplified method in determining the estimated exercise term, for all Vivint Wireless awards. Stock-based compensation expense in connection with all stock-based awards is presented as follows (in thousands): Three Months Ended September 30, Nine Months Ended September 30, 2017 2016 2017 2016 Operating expenses $ 9 $ 11 $ 49 $ 42 Selling expenses 55 49 165 (190 ) General and administrative expenses 337 448 1,073 3,486 Total stock-based compensation $ 401 $ 508 $ 1,287 $ 3,338 Stock-based compensation expense presented in selling expenses was negative for the nine months ended September 30, 2016 due to a retrospective adjustment in the grant-date fair value of a series of stock-based awards. Stock-based compensation expense included in general and administrative expenses for the nine months ended September 30, 2016 included $2.2 million of compensation related to an equity repurchase by 313 from one of the Company's executives. Capital Contribution— In 2016, Vivint Smart Home, Inc. ("Parent"), the parent company of the Company, completed issuances and sales to certain investors of shares of a series of preferred stock and contributed the net proceeds from such issuances of $100.4 million to the Company as equity contributions. These issuances were private placements exempt from registration under the U.S. Securities Act of 1933, as amended (the “Securities Act”).

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	COMMITMENTS AND CONTINGENCIES Indemnification – Subject to certain limitations, the Company is obligated to indemnify its current and former directors, officers and employees with respect to certain litigation matters and investigations that arise in connection with their service to the Company. These obligations arise under the terms of its certificate of incorporation, its bylaws, applicable contracts, and Delaware and California law. The obligation to indemnify generally means that the Company is required to pay or reimburse the individuals’ reasonable legal expenses and possibly damages and other liabilities incurred in connection with these matters. Legal – The Company is named from time to time as a party to lawsuits arising in the ordinary course of business related to its sales, marketing, the provision of its services and equipment claims. Actions filed against the Company include commercial, intellectual property, customer, and labor and employment related claims, including complaints of alleged wrongful termination and potential class action lawsuits regarding alleged violations of federal and state wage and hour and other laws. In general, litigation can be expensive and disruptive to normal business operations. Moreover, the results of legal proceedings are difficult to predict, and the costs incurred in litigation can be substantial. The Company believes the amounts provided in its financial statements are adequate in light of the probable and estimated liabilities. Factors that the Company considers in the determination of the likelihood of a loss and the estimate of the range of that loss in respect of legal matters include the merits of a particular matter, the nature of the matter, the length of time the matter has been pending, the procedural posture of the matter, how the Company intends to defend the matter, the likelihood of settling the matter and the anticipated range of a possible settlement. Because such matters are subject to many uncertainties, the ultimate outcomes are not predictable and there can be no assurances that the actual amounts required to satisfy alleged liabilities from the matters described above will not exceed the amounts reflected in the Company’s financial statements or that the matters will not have a material adverse effect on the Company’s results of operations, financial condition or cash flows. The Company regularly reviews outstanding legal claims and actions to determine if reserves for expected negative outcomes of such claims and actions are necessary. The Company had reserves for all such matters of approximately $2.1 million and $2.6 million as of September 30, 2017 and December 31, 2016 , respectively. In conjunction with one of the settlements, the Company is obligated to pay certain future royalties, based on sales of future products. Operating Leases —The Company leases office and warehouse space, certain equipment, towers, wireless spectrum, software and an aircraft under operating leases with related and unrelated parties expiring in various years through 2028 . The leases require the Company to pay additional rent for increases in operating expenses and real estate taxes and contain renewal options. The Company's operating lease arrangements and related terms consisted of the following (in thousands): Rent Expense For the three months ended, For the nine months ended , September 30, 2017 September 30, 2016 September 30, 2017 September 30, 2016 Lease Term Arrangement Warehouse, office space and other $ 3,489 $ 2,820 $ 9,374 $ 8,413 11 - 15 years Wireless towers and spectrum 1,169 1,116 3,513 3,483 1 - 10 years Total Rent Expense $ 4,658 $ 3,936 $ 12,887 $ 11,896 Capital Leases —The Company also enters into certain capital leases with expiration dates through July 2021 . On an ongoing basis, the Company enters into vehicle lease agreements under a Fleet Lease Agreement. The lease agreements are typically 36 month leases for each vehicle and the average remaining life for the fleet is 15 months as of September 30, 2017 . As of September 30, 2017 and December 31, 2016 , the capital lease obligation balance was $18.3 million and $17.7 million , respectively. Spectrum Licenses —During the year ended December 31, 2016, a subsidiary of the Company entered into leasing agreements with a third party for designated radio frequency spectrum in 40 mid-sized metropolitan markets. The initial lease term is for seven years, with an option to become the licensor of record with the FCC with respect to the applicable spectrum licenses at the end of this initial term for a nominal fee. While licenses are issued for only a fixed time, such licenses are subject to renewal by the Federal Communications Commission (FCC). The Company intends to renew the licenses at the end of the initial term. License renewals within the industry have occurred routinely and at nominal cost. Moreover, the Company has determined that there are currently no legal, regulatory, contractual, competitive, economic or other factors that limit the useful life of the licenses. As a result, the Company treats these Spectrum licenses as an indefinite-lived intangible asset. Build-to-Suit Lease Arrangements —In June 2016, the Company entered into a non-cancellable lease to occupy the Logan Facility. In 2016, because of its involvement in certain aspects of the construction of the Logan Facility, per the terms of the lease, the Company was deemed the owner of the building for accounting purposes during the construction period. Accordingly, the Company recorded a build-to-suit lease asset and a corresponding build-to-suit lease liability during the construction period. In April 2017, construction on the Logan Facility was completed and the Company commenced occupancy. In accordance with ASC 840-40 Sale-Leaseback Transactions, the building did not qualify for sale-leaseback treatment. As such, the Company will retain the building asset and corresponding lease obligation on the balance sheet. Accordingly, the Company has a build-to-suit building asset, which totaled $8.2 million and $5.0 million , respectively, net of accumulated depreciation of $0.3 million and $0 as of September 30, 2017 and December 31, 2016 , respectively.

Restructuring and Asset Impairment Charges	RESTRUCTURING AND ASSET IMPAIRMENT CHARGES During the year ended December 31, 2015, the board of directors approved a plan to transition the Company’s Wireless Internet business from a 5Ghz to a 60Ghz-based network technology (the “Wireless Restructuring”) and the Company ceased the build-out of 5Ghz networks and stopped the installation of new customers. During 2016, the Company shifted to test installations of the new 60Ghz technology. In connection with the Wireless Restructuring, the Company recorded restructuring and asset impairment charges consisting of asset impairments, the costs of employee severance, and other contract termination charges. During the three months ended September 30, 2016, the Company sold all of its New Zealand and Puerto Rico subscriber contracts and ceased operations in these geographical regions (“2016 Contract Sales”). As a result, during the three and nine months ended September 30, 2016 the Company recorded the impact of these transactions in restructuring and asset impairment. The calculation of the net loss recorded included the expensing of all unamortized deferred subscriber acquisition costs associated with the sales of the New Zealand and Puerto Rico subscriber contracts in the amount of $7.6 million , the realization of outstanding amounts of accumulated other comprehensive loss associated with the New Zealand foreign currency translation process of $1.1 million upon the substantial sale of the subsidiary, offset by cash proceeds of $6.2 million for a total net loss on the 2016 Contract Sales of $2.6 million . Restructuring and asset impairment charges and recoveries for the three and nine months ended September 30, 2017 and 2016 were as follows (in thousands): Three Months Ended Nine Months Ended September 30, 2017 September 30, 2016 September 30, 2017 September 30, 2016 Wireless restructuring and asset impairment (recoveries) charges: Recoveries of impaired assets $ — $ — $ — $ (710 ) Contract termination costs — (3 ) — — Employee severance and termination benefits charges — (103 ) — (76 ) Total wireless restructuring and asset impairment recoveries — (106 ) — (786 ) Loss on subscriber contract sales — 2,551 — 2,551 Total restructuring and asset impairment costs $ — $ 2,445 $ — $ 1,765 The following table presents accrued restructuring activity for the nine months ended September 30, 2017 (in thousands): Contract termination costs Accrued restructuring balance as of December 31, 2016 $ 649 Cash payments (68 ) Accrued restructuring balance as of September 30, 2017 $ 581 Additional charges may be incurred in the future for facility-related or other restructuring activities as the Company continues to align resources to meet the needs of the business.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation —The unaudited condensed consolidated financial statements of the Company are presented for APX Group Holdings, Inc. (“Holdings") and its wholly-owned subsidiaries. The Company has prepared the accompanying unaudited condensed consolidated financial statements pursuant to GAAP. Preparing financial statements requires the Company to make estimates and assumptions that affect the amounts that are reported in the consolidated financial statements and accompanying disclosures. Although these estimates are based on the Company’s best knowledge of current events and actions that the Company may undertake in the future, actual results may be different from the Company’s estimates. The results of operations presented herein are not necessarily indicative of the Company’s results for any future period.
Vivint Flex Pay	Vivint Flex Pay —On January 3, 2017, the Company announced the introduction of the Vivint Flex Pay plan (“Vivint Flex Pay”), which became the Company's primary sales model beginning in March 2017. Under Vivint Flex Pay, customers pay separately for the products and related installation (“Products”) and Vivint's smart home and security services (“Services”). The customer has the following three options to pay for the Products: (i) qualified customers in the United States may finance the purchase of Products through a third-party financing provider (“Consumer Financing Program”) (ii) customers not eligible for the Consumer Financing Program, but who qualify under the Company's underwriting criteria, may enter into a retail installment contract (“RIC”) directly with Vivint, or (iii) customers may purchase the Products at the outset of the service contract with cash, ACH, credit or debit card. Although customers pay separately for the Products and Services under the Vivint Flex Pay plan, the Company has determined that the shift in model does not change the Company's conclusion that the Product sales and Services are one combined unit of accounting. As a result, all forms of transactions under Vivint Flex Pay create deferred revenue for the gross amount of Products sold. Gross deferred revenues are reduced by imputed interest on the RICs and the present value of expected payments due to the third-party financing provider under the Consumer Financing Program. These deferred revenues are recognized in a pattern that reflects the estimated life of the subscriber relationships. The Company amortizes these deferred revenues over 15 years using a 240% declining balance method, which converts to a straight-line methodology after approximately nine years when the resulting amortization exceeds that from the accelerated method. Under the Consumer Financing Program, qualified customers are eligible for installment loans provided by a third-party financing provider of up to $4,000 for either 42 or 60 months. The Company pays a monthly fee to the third-party financing provider based on the average daily outstanding balance of the installment loans. Additionally, the Company shares liability for credit losses depending on the credit quality of the customer. Because of the nature of these provisions under the Consumer Financing Program, the Company records a derivative liability at its fair value when the third-party financing provider originates installment loans to customers, which reduces the amount of revenue recognized on the provision of the services. The derivative liability is reduced as payments are made from the Company to the third-party financing provider. Subsequent changes to the fair value of the derivative liability are realized through other loss/(income), net in the Condensed Consolidated Statement of Operations. (See Note 7 ).
Retail Installment Contract Receivables	Retail Installment Contract Receivables — For customers that enter into a RIC under the Vivint Flex Pay plan, the Company records a receivable for the amount financed. The RIC receivables are recorded at their present value, net of the imputed interest. At the time of installation, the Company records a long-term note receivable within long-term investments and other assets, net on the condensed consolidated balance sheets for the present value of the receivables that are expected to be collected beyond 12 months of the reporting date. The unbilled receivable amounts that are expected to be collected within 12 months of the reporting date are included as a short-term notes receivable within accounts and notes receivable, net on the condensed consolidated balance sheets. The billed amounts of notes receivables are included in accounts receivable within accounts and notes receivable, net on the condensed consolidated balance sheets. The Company imputes the interest on the RIC receivable using a risk adjusted market interest rate and records it as an adjustment to deferred revenue and as an adjustment to the face amount of the related receivable. The imputed interest income is recognized over the term of the RIC contract as recurring and other revenue on the condensed consolidated statement of operations. When the Company determines that there are RIC receivables that have become uncollectible, the Company records an allowance for credit losses and bad debt expense. The estimate of allowance for credit losses considers a number of factors, including collection experience, aging of the remaining RIC receivable portfolios, credit quality of the subscriber base and other qualitative considerations, including macro-economic factors. Account balances are written-off if collection efforts are unsuccessful and future collection is unlikely based on the length of time from the day accounts become past due. As of September 30, 2017 and December 31, 2016 there was no allowance for credit losses associated with RIC receivables (See Note 3 )
Accounts Receivable	Accounts Receivable — Accounts receivable consists primarily of amounts due from customers for recurring monthly monitoring services and the billed portion of RIC receivables. The accounts receivable are recorded at invoiced amounts and are non-interest bearing and are included within accounts and notes receivable, net on the condensed consolidated balance sheets. Accounts receivable totaled $20.7 million and $12.9 million at September 30, 2017 and December 31, 2016 , respectively net of the allowance for doubtful accounts of $4.5 million and $4.1 million at September 30, 2017 and December 31, 2016 , respectively. The Company estimates this allowance based on historical collection experience and subscriber attrition rates. When the Company determines that there are accounts receivable that are uncollectible, they are charged off against the allowance for doubtful accounts. As of September 30, 2017 and December 31, 2016 , no accounts receivable were classified as held for sale. The provision for doubtful accounts is included in general and administrative expenses in the accompanying unaudited condensed consolidated statements of operations and totaled $5.0 million and $5.6 million for the three months ended September 30, 2017 and 2016 , respectively.
Revenue Recognition	Revenue Recognition— The Company recognizes revenue principally on three types of transactions: (i) recurring and other revenue, which includes revenues for monitoring and other smart home services, recognition of deferred revenue associated with the sales of Products at the time of installation, imputed interest associated with the RIC receivables and recurring monthly revenue associated with Vivint Wireless Inc. (“Wireless Internet” or “Wireless”) , (ii) service and other sales, which includes non-recurring service fees charged to subscribers provided on contracts, contract fulfillment revenues and sales of products that are not part of the Company's service offerings, and (iii) activation fees on subscriber contracts, which are amortized over the expected life of the customer. Recurring and other revenue includes (i) the Company’s subscriber contracts associated with Services, which are billed directly to the subscriber in advance, generally monthly, pursuant to the terms of subscriber contracts and recognized ratably over the service period, (ii) monthly recognition of deferred Product revenue and (iii) imputed interest associated with the RIC receivables, which is recognized over the initial term of the RIC. Service and other sales revenue is recognized as services are provided or when title to the products and equipment sold transfers to the customer. Contract fulfillment revenue, included in service and other sales, is recognized when payment is received from customers who cancel their contract in-term. Revenue from sales of products that are not part of the service offering and sold after the initial point of installation is generally recognized upon delivery of products. Activation fees represent upfront one-time charges billed to subscribers at the time of installation and are deferred. The Company amortizes deferred activation fees over 15 years using a 240% declining balance method, which converts to a straight-line methodology after approximately nine years when the resulting amortization exceeds that from the accelerated method. The Company evaluates subscriber account attrition on a periodic basis, utilizing observed attrition rates for the Company’s subscriber contracts and industry information and, when necessary, makes adjustments to the estimated subscriber relationship period and amortization method. Activation fees are no longer charged under Vivint Flex Pay, as these fees will no longer be billed separately to subscribers at the time of installation.
Deferred Revenue	Deferred Revenue— The Company's deferred revenues primarily consist of amounts for sales of Products and Services. Deferred Product revenues are recorded at the time of sale and deferred in a pattern that reflects the estimated life of the subscriber relationships. The Company amortizes these deferred revenues over 15 years using a 240% declining balance method, which converts to a straight-line methodology after approximately nine years when the resulting amortization exceeds that from the accelerated method. Deferred Service revenues represent the amounts billed, generally monthly, in advance and collected from customers for services yet to be performed.
Subscriber Acquisition Costs	Subscriber Acquisition Costs — Subscriber acquisition costs represent the costs related to the origination of new subscribers. A portion of subscriber acquisition costs is expensed as incurred, which includes costs associated with the direct-to-home sale housing, marketing and recruiting, certain portions of sales commissions (residuals), overhead and other costs, considered not directly and specifically tied to the origination of a particular subscriber. The remaining portion of the costs is considered to be directly tied to subscriber acquisition and consists primarily of certain portions of sales commissions, equipment and installation costs. These costs are deferred and recognized in a pattern that reflects the estimated life of the subscriber relationships. The Company amortizes subscriber acquisition costs over 15 years using a 240% declining balance method, which converts to a straight-line methodology after approximately nine years when the resulting amortization exceeds that from the accelerated method. The Company evaluates subscriber account attrition on a periodic basis, utilizing observed attrition rates for the Company’s subscriber contracts and industry information and, when necessary, makes adjustments to the estimated subscriber relationship period and amortization method. On the condensed consolidated statement of cash flows, subscriber acquisition costs that are comprised of equipment and related installation costs purchased for or used in subscriber contracts in which the Company retains ownership to the equipment are classified as investing activities and reported as “Subscriber acquisition costs – company owned equipment”. All other subscriber acquisition costs are classified as operating activities and reported as “Subscriber acquisition costs – deferred contract costs” on the condensed consolidated statements of cash flows as these assets represent deferred costs associated with customer contracts.
Cash and Cash Equivalents	Cash and Cash Equivalents— Cash and cash equivalents consists of highly liquid investments with remaining maturities when purchased of three months or less.
Inventories	Inventories —Inventories, which are comprised of smart home and security system equipment and parts, are stated at the lower of cost or net realizable value with cost determined under the first-in, first-out (FIFO) method. The Company adjusts the inventory balance based on anticipated obsolescence, usage and historical write-offs.
Long-lived Assets and Intangibles	Long-lived Assets and Intangibles — Property, plant and equipment are stated at cost and depreciated on the straight-line method over the estimated useful lives of the assets or the lease term for assets under capital leases, whichever is shorter. Intangible assets with definite lives are amortized over the remaining estimated economic life of the underlying technology or relationships, which ranges from five to ten years . Definite-lived intangible assets are amortized on the straight-line method over the estimated useful life of the asset or in a pattern in which the economic benefits of the intangible asset are consumed. Amortization expense associated with leased assets is included with depreciation expense. Routine repairs and maintenance are charged to expense as incurred. The Company periodically assesses potential impairment of its long-lived assets and intangibles and performs an impairment review whenever events or changes in circumstances indicate that the carrying value may not be recoverable. In addition, the Company periodically assesses whether events or changes in circumstance continue to support an indefinite life of certain intangible assets or warrant a revision to the estimated useful life of definite-lived intangible assets. Wireless Spectrum Licenses —The Company has capitalized, as an intangible asset, wireless spectrum licenses that its subsidiary acquired from a third party. The cost basis of the wireless spectrum asset includes the purchase price paid for the licenses at the time of acquisition, plus costs incurred to acquire the licenses. The asset and related liability were recorded at the net present value of future cash outflows using the Company's incremental borrowing rate at the time of acquisition. The Company has determined that the wireless spectrum licenses meet the definition of indefinite-lived intangible assets because the licenses may be renewed periodically for a nominal fee, provided that the Company continues to meet the service and geographic coverage provisions. The Company has also determined that there are currently no legal, regulatory, contractual, competitive, economic or other factors that limit the useful lives of these wireless spectrum licenses.
Long-term Investments	Long-term Investments —The Company’s long-term investments are comprised of available-for-sale securities and cost-based investments in other companies. As of September 30, 2017 and December 31, 2016 , cost-based investments totaled $0.6 million and $0.4 million and available-for-sale securities totaled $3.7 million and $4.0 million , respectively. The Company’s marketable equity securities have been classified and accounted for as available-for-sale. Management determines the appropriate classification of its investments at the time of purchase and reevaluates the classifications at each balance sheet date. Marketable equity securities, are classified as either short-term or long-term, based on the nature of each security and its availability for use in current operations. The Company’s marketable equity securities are carried at fair value, with unrealized gains and losses, reported as a component of accumulated other comprehensive income (“AOCI”) in equity, with the exception of unrealized losses believed to be other-than-temporary which are reported in earnings in the current period. The cost of securities sold is based upon the specific identification method. The Company performs impairment analyses of its cost based investments when events occur or circumstances change that would, more likely than not, reduce the fair value of the investment below its carrying value. When indicators of impairment do not exist and certain accounting criteria are met, the Company evaluates impairment using a qualitative approach. As of September 30, 2017 and December 31, 2016 , no indicators of impairment existed associated with these cost based investments.
Deferred Financing Costs	Deferred Financing Costs —Costs incurred in connection with obtaining debt financing are deferred and amortized utilizing the straight-line method, which approximates the effective-interest method, over the life of the related financing. Deferred financing costs incurred with draw downs on APX Group, Inc.’s (“APX”) revolving credit facility will be amortized over the amended maturity dates discussed in Note 2 . If such financing is paid off or replaced prior to maturity with debt instruments that have substantially different terms, the unamortized costs are charged to expense.
Residual Income Plan	Residual Income Plan —The Company has a program that allows certain third-party sales channel partners to receive additional compensation based on the performance of the underlying contracts they create. The Company calculates the present value of the expected future payments and recognizes this amount in the period the commissions are earned. Subsequent accretion and adjustments to the estimated liability are recorded as interest and operating expense, respectively. The Company monitors actual payments and customer attrition on a periodic basis and, when necessary, makes adjustments to the liability.
Stock-Based Compensation	Stock-Based Compensation —The Company measures compensation costs based on the grant-date fair value of the award and recognizes that cost over the requisite service period of the awards (See Note 9 ). During the first quarter of 2017, the Company adopted Accounting Standard Update (“ASU”) 2016-09. Under the provisions of ASU 2016-09, the Company has elected to recognize the impact of forfeitures when they occur with no adjustment for estimated forfeitures and recognizes excess tax benefits as a reduction of income tax expense regardless of whether the benefit reduces income taxes payable. Additionally, the Company recognizes the cash flow impact of such excess tax benefits in operating activities in the condensed consolidated statements of cash flows. The Company adopted ASU 2016-09 on a modified retrospective basis for the income statement impact of forfeitures and income taxes and have retrospectively applied ASU 2016-09 to its condensed consolidated statements of cash flows for the impact of excess tax benefits. Accordingly, the Company recognized an immaterial cumulative adjustment charge for the adoption of the impact of forfeitures to beginning retained earnings as of January 1, 2017.
Advertising Expense	Advertising Expense —Advertising costs are expensed as incurred.
Income Taxes	Income Taxes —The Company accounts for income taxes based on the asset and liability method. Under the asset and liability method, deferred tax assets and deferred tax liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Valuation allowances are established when necessary to reduce deferred tax assets when it is determined that it is more likely than not that some portion of the deferred tax asset will not be realized. The Company recognizes the effect of an uncertain income tax position on the income tax return at the largest amount that is more-likely-than-not to be sustained upon audit by the relevant taxing authority. An uncertain income tax position will not be recognized if it has less than a 50% likelihood of being sustained. The Company’s policy for recording interest and penalties is to record such items as a component of the provision for income taxes.
Concentrations of Credit Risk	Concentrations of Credit Risk —Financial instruments that potentially subject the Company to concentration of credit risk consist principally of receivables and cash. At times during the year, the Company maintains cash balances in excess of insured limits. The Company is not dependent on any single customer or geographic location. The loss of a customer would not adversely impact the Company’s operating results or financial position.
Concentrations of Supply Risk	Concentrations of Supply Risk —As of September 30, 2017 , approximately 68% of the Company’s installed panels were SkyControl panels and 30% were 2GIG Go!Control panels. In connection with the 2GIG Sale in April 2013, the Company entered into a five -year supply agreement with 2GIG, pursuant to which they will be the exclusive provider of the Company’s control panel requirements, subject to certain exceptions as provided in the supply agreement. The loss of 2GIG as a supplier could potentially impact the Company’s operating results or financial position.
Fair Value Measurement	Fair Value Measurement —Fair value is based on the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Assets and liabilities subject to on-going fair value measurement are categorized and disclosed into one of three categories depending on observable or unobservable inputs employed in the measurement. These two types of inputs have created the following fair value hierarchy: Level 1: Quoted prices in active markets that are accessible at the measurement date for assets and liabilities. Level 2: Observable prices that are based on inputs not quoted in active markets, but corroborated by market data. Level 3: Unobservable inputs are used when little or no market data is available. This hierarchy requires the Company to minimize the use of unobservable inputs and to use observable market data, if available, when determining fair value. The Company recognizes transfers between levels of the hierarchy based on the fair values of the respective financial measurements at the end of the reporting period in which the transfer occurred. There were no transfers between levels of the fair value hierarchy during the nine months ended September 30, 2017 and 2016 . The carrying amounts of the Company’s accounts receivable, accounts payable and accrued and other liabilities approximate their fair values due to their short maturities.
Goodwill	Goodwill —The Company conducts a goodwill impairment analysis annually in the fourth fiscal quarter, as of October 1, and as necessary if changes in facts and circumstances indicate that the fair value of the Company’s reporting units may be less than its carrying amount. When indicators of impairment do not exist and certain accounting criteria are met, the Company is able to evaluate goodwill impairment using a qualitative approach. When necessary, the Company’s quantitative goodwill impairment test consists of two steps. The first step requires that the Company compare the estimated fair value of its reporting units to the carrying value of the reporting unit’s net assets, including goodwill. If the fair value of the reporting unit is greater than the carrying value of its net assets, goodwill is not considered to be impaired and no further testing is required. If the fair value of the reporting unit is less than the carrying value of its net assets, the Company would be required to complete the second step of the test by analyzing the fair value of its goodwill. If the carrying value of the goodwill exceeds its fair value, an impairment charge is recorded. As of September 30, 2017 , there were no changes in facts and circumstances since the most recent annual impairment analysis to indicate impairment existed.
Foreign Currency Translation and Other Comprehensive Income	Foreign Currency Translation and Other Comprehensive Income —The functional currencies of Vivint Canada, Inc. and Vivint New Zealand, Ltd. are the Canadian and New Zealand dollars, respectively. Accordingly, assets and liabilities are translated from their respective functional currencies into U.S. dollars at period-end rates and revenue and expenses are translated at the weighted-average exchange rates for the period. Adjustments resulting from this translation process are classified as other comprehensive income (loss) and shown as a separate component of equity. During the three months ended September 30, 2016, the Company sold all of its New Zealand and Puerto Rico subscriber contracts and ceased operations in these geographical regions (“2016 Contract Sales”). See Note 13 for further information on the 2016 Contract Sales. When intercompany foreign currency transactions between entities included in the consolidated financial statements are of a long term investment nature (i.e., those for which settlement is not planned or anticipated in the foreseeable future) foreign currency translation adjustments resulting from those transactions are included in stockholders’ deficit as accumulated other comprehensive loss. When intercompany transactions are deemed to be of a short term nature, translation adjustments are required to be included in the condensed consolidated statement of operations.
Letters of Credit	Letters of Credit —As of September 30, 2017 and December 31, 2016 , the Company had $8.7 million and $5.7 million , respectively, of letters of credit issued in the ordinary course of business, all of which are undrawn.
Restructuring and Asset Impairment Charges	Restructuring and Asset Impairment Charges —Restructuring and asset impairment charges represent expenses incurred in relation to activities to exit or dispose of portions of the Company's business that do not qualify as discontinued operations. Liabilities associated with restructuring are measured at their fair value when the liability is incurred. Expenses for related termination benefits are recognized at the date the Company notifies the employee, unless the employee must provide future service, in which case the benefits are expensed ratably over the future service period. Liabilities related to termination of a contract are measured and recognized at fair value when the contract does not have any future economic benefit to the entity and the fair value of the liability is determined based on the present value of the remaining obligation. The Company expenses all other costs related to an exit or disposal activity as incurred (See Note 13 ).
New Accounting Pronouncements	New Accounting Pronouncements —In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers (Topic 606),” which supersedes the revenue recognition requirements in “Revenue Recognition (Topic 605).” Under Topic 606, revenue is recognized when a customer obtains control of promised goods or services and is recognized in an amount that reflects the consideration which the entity expects to receive in exchange for those goods or services. In addition, Topic 606 requires enhanced disclosures, including disclosure of the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. The FASB has recently issued several amendments to the standard, including clarification on accounting for licenses of intellectual property and identifying performance obligations. Topic 606 will be effective for the Company beginning with the first quarter of fiscal 2018. The Company offers its customers a smart home service combining its proprietary control panel; equipment in the home that interfaces with the control panel, including door and window sensors, door locks, security cameras and smoke alarms (“Interfacing Equipment”); installation; and its proprietary back end cloud platform software and services. These combined elements together create an integrated system that allows the Company’s customers to monitor, control and protect their home (“Smart Home Service”). Based on the Company’s assessment of the potential impacts of Topic 606, it expects to continue to recognize most revenue over time for its Smart Home contracts based on the life of the contract, which is included in Recurring and other revenue on the Company’s Statement of Operations. The Company has preliminarily concluded that, while certain equipment provided to its customers may be capable of being distinct, its customers are buying an integrated system that provides them Smart Home Services. The equipment and services contracted for by the customer are necessary to provide the integrated system the customer has contracted for. Because the equipment and services included in the customer’s contract are integrated and highly interdependent, and because they must work together to deliver the Smart Home Services, the Company has preliminarily concluded that the Interfacing Equipment, control panel, related installation and Smart Home Services contracted for by the customer are generally not distinct within the context of the contract and, therefore, constitute a single, combined performance obligation. This single, combined performance obligation will be recognized over the customer’s contract term, whereas under Topic 605 the revenue was recorded over the expected customer life. Interfacing Equipment purchased subsequent to the purchase of the initial system and the related installation services will be treated as a contract modification. If the Company determines that certain equipment is capable of being distinct, and distinct within the context of the contract, revenue for that equipment will be recognized upon delivery. Discounts and other concessions will be estimated and accrued for on a monthly basis based on the Company’s historical trends of offering discounts and concessions to its customers. Service and other sales revenue will continue to be recognized at the time the Company performs services for its customers. More judgment and estimates will be required under Topic 606 than are required under Topic 605, including estimating the SSP for each performance obligation identified within the Company’s contracts. The Company is currently performing analyses to determine the SSP for each of the performance obligations that have been identified. The Company is currently calculating its SSPs based on its historical pricing practices. Due to the complexity of certain contracts, the actual revenue recognition treatment required under Topic 606 for these arrangements may depend on contract- specific terms and vary in some instances. Topic 606 permits two methods of adoption: retrospectively to each prior reporting period presented (full retrospective method), or modified retrospectively with the cumulative effect of initially applying the guidance recognized at the date of initial application (the cumulative catch-up transition method). The Company currently anticipates adopting the standard using the cumulative catch-up transition method. Under the cumulative catch-up transition method, the Company will evaluate each contract that is effective on the adoption date as if that contract had been accounted for under Topic 606 from contract inception. Some revenue related to customer Smart Home contracts that would have been recognized in future periods under Topic 605 (based on expected customer life) will be recast under Topic 606 (based on contract term) as if the revenue had been recognized in prior periods. As this transition method requires that the Company not adjust historical reported revenue amounts, the revenue that would have been recognized under this method prior to the adoption date will be an adjustment to retained earnings and will not be recognized as revenue in future periods as previously planned. Topic 606 also requires the deferral of incremental costs of obtaining a contract with a customer. The Company is deferring these same costs under Topic 605. It does not anticipate any significant change in contract costs that are capitalized or the period over which they are expensed. Refer to Subscriber Acquisition Costs in Note 2 for further detail. In June 2016, the FASB issued ASU 2016-13 which modifies the measurement of expected credit losses of certain financial instruments. This update is effective for fiscal years, and interim periods within those years, beginning after December 15, 2019 and must be applied using a modified-retrospective approach, with early adoption permitted. The Company does not believe the adoption of ASU 2016-13 will have a material impact on the consolidated financial statements. In February 2016, the FASB issued ASU 2016-02 to increase transparency and comparability among organizations as it relates to lease assets and lease liabilities. The update requires that lease assets and lease liabilities be recognized on the balance sheet, and that key information about leasing arrangements be disclosed. Prior to this update, GAAP did not require operating leases to be recognized as lease assets and lease liabilities on the balance sheet. This update is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018 and must be applied using a modified retrospective approach, with early adoption permitted. The Company is in the initial stages of evaluating the impact of ASU 2016-02 on its accounting policies, processes, and system requirements. The Company’s current operating lease portfolio is primarily comprised of network, real estate, and equipment leases. Upon adoption of this standard, the Company expects the balance sheet to include a right of use asset and liability related to substantially all operating lease arrangements. The Company has assigned internal resources to perform the evaluation. Furthermore, the Company has made and will continue to make investments in systems to enable timely and accurate reporting under the new standard. While the Company continues to assess the potential impacts of ASU 2016-02, including the areas described above, and anticipate this standard could have a material impact on the consolidated financial statements, the Company does not know or cannot reasonably estimate quantitative information related to the impact of the new standard on the financial statements at this time.
