Accounting Policies [Abstract]
Significant Accounting Policies	Significant Accounting Policies Basis of Presentation The Company has prepared the accompanying consolidated financial statements pursuant to generally accepted accounting principles in the United States (“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 The Vivint Flex Pay plan (“Vivint Flex Pay”) became the Company’s primary sales model beginning in March 2017. Under Vivint Flex Pay, customers pay separately for the products (including control panel, security peripheral equipment, smart home equipment, and related installation) (“Products”) and Vivint’s smart home and security services (“Services”). The customer has the following three ways to pay for the Products: (1) qualified customers in the United States may finance the purchase of Products through a third-party financing providers (“Consumer Financing Program”) (2) the Company offers to some 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 (3) customers may purchase the Products at the outset of the service contract by check, automatic clearing house payments (“ACH”), credit or debit card. Although customers pay separately for Products and Services under the Vivint Flex Pay plan, the Company has determined that the shift in its sales model does not change the Company's conclusion that the sale of Products and Services are one single performance obligation. 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. Under the Consumer Financing Program, qualified customers are eligible for loans provided by third-party financing providers of up to $4,000 . The annual percentage rates on these loans range between 0% and 9.99% , based on the customer's credit quality, and are either installment or revolving loans with a 42 or 60 month term. For certain third-party provider loans, the Company pays a monthly fee based on either the average daily outstanding balance of the loans or the number of outstanding loans, depending on the third-party financing provider and the Company shares liability for credit losses, with the Company being responsible for between 5% and 100% of lost principal balances. Additionally, the Company is responsible for reimbursing certain third-party financing providers for credit card transaction fees associated with the loans. Because of the nature of these provisions, the Company records a derivative liability at its fair value when the third-party financing provider originates loans to customers, which reduces the amount of estimated revenue recognized on the provision of the services. The derivative liability is reduced as payments are made by the Company to the third-party financing provider. Subsequent changes to the fair value of the derivative liability are realized through other expenses (income), net in the Consolidated Statement of Operations. (See Note 9 ). For other third-party loans, the Company receives net proceeds (net of fees and expected losses) for which the Company has no further obligation to the third-party. The Company records these net proceeds to deferred revenue. Retail Installment Contract Receivables For subscribers that enter into a RIC to finance the purchase of Products and related installation, the Company records a receivable for the amount financed. Gross RIC receivables are reduced for (i) expected write-offs of uncollectible balances over the term of the RIC and (ii) a present value discount of the expected cash flows using a risk adjusted market interest rate (together, the “RIC Discount”). Therefore, the RIC receivables equal the present value of the expected cash flows to be received by the Company over the term of the RIC. At the time of installation, the Company records a long-term note receivable within long-term notes receivables and other assets, net on the 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 consolidated balance sheets. The billed amounts of notes receivables are included in accounts receivable within accounts and notes receivable, net on the 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 risk adjusted interest rate considers a number of factors, including credit quality of the subscriber base and other qualitative considerations such as macro-economic factors. The imputed interest income is recognized over the term of the RIC contract as recurring and other revenue on the consolidated statements of operations. When the Company determines that there are RIC receivables that have become uncollectible, it records an adjustment to the RIC Discount and reduces the related note receivable balance. On a regular basis, the Company also assesses the level of the RIC Discount balance based on historical RIC write-off trends and adjusts the balance, if necessary. 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. (See Note 4 ). Revenue Recognition The Company offers its customers smart home services combining Products, including a proprietary control panel, door and window sensors, door locks, security cameras and smoke alarms; installation; and a proprietary back-end cloud platform software and Services. These together create an integrated system that allows the Company’s customers to monitor, control and protect their home (“Smart Home Services”). The Company’s customers are buying this integrated system that provides them with these Smart Home Services. The number and type of Products purchased by a customer depends on their desired functionality. Because the Products 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 concluded that installed Products, related installation and Services contracted for by the customer are generally not distinct within the context of the contract and, therefore, constitute a single, combined performance obligation. Revenues for this single, combined performance obligation are recognized on a straight-line basis over the customer’s contract term, which is the period in which the parties to the contract have enforceable rights and obligations. The Company has determined that certain contracts that do not require a long-term commitment for monitoring services by the customer contain a material right to renew the contract, because the customer does not have to purchase Products upon renewal. Proceeds allocated to the material right are recognized over the period benefit, which is generally three years . The majority of the Company’s subscription contracts are between three and five years in length and are non-cancelable. These contracts with customers generally convert into month-to-month agreements at the end of the initial term, and some customer contracts are month-to-month from inception. Payment for recurring monitoring and other Smart Home Services is generally due in advance on a monthly basis. Sales of Products and other one-time fees such as service fees or installation fees are invoiced to the customer at the time of sale. Revenues for wireless internet service that were provided by Vivint Wireless Inc. (“Wireless Internet” or “Wireless”) and any Products or Services that are considered separate performance obligations are recognized when those Products or Services are delivered. Taxes collected from customers and remitted to governmental authorities are not included in revenue. Payments received or amounts billed in advance of revenue recognition are reported as deferred revenue. Deferred Revenue The Company's deferred revenues primarily consist of amounts for sales (including upfront proceeds) of Smart Home Services. Deferred revenues are recognized over the term of the related performance obligation, which is generally three to five years . 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 consolidated balance sheets. Accounts receivable totaled $20.5 million and $16.5 million and December 31, 2019 and 2018 , respectively net of the allowance for doubtful accounts of $8.1 million and $5.6 million at December 31, 2019 and 2018 , 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. The provision for doubtful accounts is included in general and administrative expenses in the accompanying consolidated statements of operations and totaled $25.0 million and $19.4 million for the years ended December 31, 2019 and 2018 , respectively. The changes in the Company’s allowance for accounts receivable were as follows for the periods ended (in thousands): Year ended December 31, 2019 2018 2017 Beginning balance $ 5,594 $ 5,356 $ 4,138 Provision for doubtful accounts 25,043 19,405 22,465 Write-offs and adjustments (22,519 ) (19,167 ) (21,247 ) Balance at end of period $ 8,118 $ 5,594 $ 5,356 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 10 ). Principles of Consolidation 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. Capitalized Contract Costs Capitalized contract costs represent the costs directly related and incremental to the origination of new contracts, modification of existing contracts or to the fulfillment of the related subscriber contracts. These include commissions, other compensation and related costs incurred directly for the origination and installation of new or upgraded customer contracts, as well as the cost of Products installed in the customer home at the commencement or modification of the contract. The Company calculates amortization by accumulating all deferred contract costs into separate portfolios based on the initial month of service and amortizes those deferred contract costs on a straight-line basis over the expected period of benefit that the Company has determined to be five years , consistent with the pattern in which the Company provides services to its customers. The Company believes this pattern of amortization appropriately reduces the carrying value of the capitalized contract costs over time to reflect the decline in the value of the assets as the remaining period of benefit for each monthly portfolio of contracts decreases. The period of benefit of five years is longer than a typical contract term because of anticipated contract renewals. The Company applies this period of benefit to its entire portfolio of contracts. The Company updates its estimate of the period of benefit periodically and whenever events or circumstances indicate that the period of benefit could change significantly. Such changes, if any, are accounted for prospectively as a change in estimate. Amortization of capitalized contract costs is included in “Depreciation and Amortization” on the consolidated statements of operations. The carrying amount of the capitalized contract costs is periodically reviewed for impairment. In performing this review, the Company considers whether the carrying amount of the capitalized contract costs will be recovered. In estimating the amount of consideration the Company expects to receive in the future related to capitalized contract costs, the Company considers factors such as attrition rates, economic factors, and industry developments, among other factors. If it is determined that capitalized contract costs are impaired, an impairment loss is recognized for the amount by which the carrying amount of the capitalized contract costs and the anticipated costs that relate directly to providing the future services exceed the consideration that has been received and that is expected to be received in the future. Contract costs not directly related and incremental to the origination of new contracts, modification of existing contracts or to the fulfillment of the related subscriber contracts are expensed as incurred. These costs include those associated with housing, marketing and recruiting, non-direct lead generation costs, certain portions of sales commissions and residuals, overhead and other costs considered not directly and specifically tied to the origination of a particular subscriber. On the consolidated statement of cash flows, capitalized contract costs are classified as operating activities and reported as “Capitalized contract costs - deferred contract costs” as these assets represent deferred costs associated with subscriber 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. Inventories sold to customers as part of a smart home and security system are generally capitalized as capitalized contract costs. The Company adjusts the inventories balance based on anticipated obsolescence, usage and historical write-offs. Property, Plant and Equipment and Long-lived Assets 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 finance 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 2 to 10 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 reviews long-lived assets, including property, plant and equipment, capitalized contract costs, and definite-lived intangibles for impairment when events or changes in circumstances indicate that the carrying amount may not be recoverable. The Company considers whether or not indicators of impairment exist on a regular basis and as part of each quarterly and annual financial statement close process. Factors the Company considers in determining whether or not indicators of impairment exist include market factors and patterns of customer attrition. If indicators of impairment are identified, the Company estimates the fair value of the assets. An impairment loss is recognized if the carrying amount of a long-lived asset is not recoverable and exceeds its fair value. The Company conducts an indefinite-lived intangible impairment analysis annually as of October 1, and as necessary if changes in facts and circumstances indicate that the fair value of the Company’s indefinite-lived intangibles may be less than the carrying amount. When indicators of impairment do not exist and certain accounting criteria are met, the Company is able to evaluate indefinite-lived intangible impairment using a qualitative approach. When necessary, the Company’s quantitative impairment test consists of two steps. The first step requires that the Company compare the estimated fair value of its indefinite-lived intangibles to the carrying value. If the fair value is greater than the carrying value, the intangibles are not considered to be impaired and no further testing is required. If the fair value is less than the carrying value, an impairment loss in an amount equal to the difference is recorded. During the years ended December 31, 2019 , 2018 and 2017 , no impairments to long-lived assets or intangibles were recorded. The Company’s depreciation and amortization included in the consolidated statements of operations consisted of the following (in thousands): Year ended December 31, 2019 2018 2017 Amortization of capitalized contract costs $ 437,285 $ 398,174 $ — Amortization of subscriber acquisition costs — — 206,153 Amortization of definite-lived intangibles 80,468 90,945 101,827 Depreciation of property, plant and equipment 25,687 24,963 21,275 Total depreciation and amortization $ 543,440 $ 514,082 $ 329,255 Wireless Spectrum Licenses The Company had capitalized as an intangible asset wireless spectrum licenses that were acquired from third parties. 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 determined that the wireless spectrum licenses met the definition of indefinite-lived intangible assets because the licenses were able to be renewed periodically for a nominal fee, provided that the Company continued to meet the service and geographic coverage provisions. In January 2018, the Company terminated the wireless spectrum licenses for cash consideration. See Note 8 for further discussion. Leases Effective January 1, 2019 the Company accounts for leases under Topic 842 (see Recently Adopted Accounting Standards below). Under Topic 842, the Company determines if an arrangement is a lease at inception. Lease right-of-use (“ROU”) assets represent the Company's right to use an underlying asset for the lease term and lease liabilities represent the obligation to make lease payments arising from the lease. Lease ROU assets and liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. In determining the present value of lease payments, the Company uses the implicit rate when available. When implicit rates are not available, the Company uses an incremental borrowing rate based on the information available at commencement date. The lease ROU asset also includes any lease payments made and is reduced by lease incentives. Lease expense for lease payments is recognized on a straight-line basis over the lease term. The Company does not record lease ROU assets and liabilities for leases with terms of 12 months or less. Leases are classified as either operating or finance at lease inception. Operating lease assets and liabilities and finance lease liabilities are stated separately on the consolidated balance sheets. Finance lease assets are included in property, plant and equipment, net on the consolidated balance sheets. The Company has lease agreements with lease and non-lease components. For facility type leases, the Company separates the lease and non-lease components. Generally, the Company accounts for the lease and non-lease components as a single lease component for all other class of leases. Prior to the adoption of Topic 842, the Company's leases were classified as either operating or capital leases. Capital lease liabilities were stated separately on the consolidated balance sheets and capital lease assets were included in property, plant and equipment, net on the consolidated balance sheets. Operating leases were not recognized in the balance sheet. Capital lease balances are presented on the same lines as finance lease balances for comparative prior periods in the unaudited consolidated financial statements. See Recently Adopted Accounting Standards below and note 14 "Leases" for additional information related to the impact of adopting Topic 842. Long-term Investments The Company’s long-term investments are composed of equity securities in certain companies. As of December 31, 2018 , the Company's equity investments totaled $3.9 million . The Company did not hold any equity security investments as of December 31, 2019 . Management determines the appropriate fair value measurement of its investments at the time of purchase and reevaluates the fair value measurement at each balance sheet date. 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 equity securities are carried at fair value, with gains and losses, reported in other income or loss within the statement of operations The Company performs impairment analyses of its investments without readily determinable fair values 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, the Company evaluates impairment using a qualitative approach. Additionally, increases or decreases in the carrying amount resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer are adjusted through the statement of operations as needed. Deferred Financing Costs Certain 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 associated with obtaining APX's revolving credit facility are amortized over the amended maturity dates discussed in Note 5 . Deferred costs associated with the revolving credit facitliy reported in the accompanying consolidated balance sheets as deferred financing costs, net at December 31, 2019 and 2018 were $1.1 million and $2.1 million , net of accumulated amortization of $10.6 million and $9.6 million , respectively. Deferred financing costs included in the accompanying consolidated balance sheets within notes payable, net at December 31, 2019 and 2018 were $27.0 million and $32.4 million , net of accumulated amortization of $63.5 million and $54.6 million , respectively. Amortization expense on deferred financing costs recognized and included in interest expense in the accompanying consolidated statements of operations totaled $9.8 million , $10.4 million and $11.4 million for the years ended December 31, 2019 , 2018 and 2017 , respectively. Residual Income Plans 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 “Channel Partner Plan”). The Company also has a residual sales compensation plan (the “Residual Plan”) under which the Company's sales personnel (each, a “Plan Participant”) receive compensation based on the performance of the underlying contracts they create. For both the Channel Partner Plan and Residual Plan, the Company calculates the present value of the expected future residual payments and records a liability for this amount in the period the subscriber account is originated. These costs are recorded to capitalized contract costs. 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 $4.5 million and $4.5 million as of December 31, 2019 and 2018 , respectively, and the amount included in other long-term obligations was $20.7 million and $13.0 million at December 31, 2019 and 2018 , respectively. Stock-Based Compensation The Company measures compensation cost based on the grant-date fair value of the award and recognizes that cost over the requisite service period of the awards (See Note 12 ). Advertising Expense Advertising costs are expensed as incurred. Advertising costs were approximately $60.4 million , $47.2 million and $42.5 million for the years ended December 31, 2019 , 2018 and 2017 , respectively. 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, or all, 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. Changes in tax laws and rates could also affect recorded deferred tax assets and liabilities in the future. The Company records the effect of a tax rate or law change on the Company’s deferred tax assets and liabilities in the period of enactment. Future tax rate or law changes could have a material effect on the Company’s results of operations, financial condition, or cash flows (See Note 11 ). 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 December 31, 2019 , approximately 88% of the Company’s installed panels were SkyControl panels, 12% were 2GIG Go!Control panels. During 2018 the Company transitioned to a new panel supplier. The loss of the Company's panel supplier could potentially impact its 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 years ended December 31, 2019 and 2018 . 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 their carrying amounts. 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. The Company’s reporting units are determined based on its current reporting structure, which as of December 31, 2019 consisted of one reporting unit. The Company found that no indicators of goodwill impairment existed during the year ended December 31, 2019 , thus a qualitative approach was used and it was determined that no impairment existed for goodwill. During the years ended December 31, 2019 , 2018 and 2017 , no impairments to goodwill were recorded. Foreign Currency Translation and Other Comprehensive Income The functional currency of Vivint Canada, Inc. is the Canadian dollar. Accordingly, Vivint Canada, Inc. assets and liabilities are translated from their respective functional currencies into U.S. dollars at period-end rates and Vivint Canada, Inc. 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 (loss) income and shown as a separate component of equity. 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) equity as accumulated other comprehensive loss or income. When intercompany transactions are deemed to be of a short term nature, transl

Revenue from Contract with Customer [Abstract]
Revenue and Capitalized Contract Costs	Revenue and Capitalized Contract Costs Customers are typically invoiced for Smart Home Services in advance or at the time the Company delivers the related Smart Home Services. The majority of customers pay at the time of invoice via credit card, debit card or ACH. Deferred revenue relates to the advance consideration received from customers, which precedes the Company’s satisfaction of the associated performance obligation. The Company’s deferred revenues primarily result from customer payments received in advance for recurring monthly monitoring and other Smart Home Services, or other one-time fees, because these performance obligations are satisfied over time. During the years ended December 31, 2019 and 2018 , the Company recognized revenues of $225.9 million and $144.1 million , respectively, that were included in the deferred revenue balance as of December 31, 2018 and 2017 , respectively. Transaction Price Allocated to the Remaining Performance Obligations As of December 31, 2019 , approximately $2.6 billion of revenue is expected to be recognized from remaining performance obligations for subscription contracts. The Company expects to recognize approximately 61% of the revenue related to these remaining performance obligations over the next 24 months, with the remaining balance recognized over an additional 36 months. Financial Statement Impact of Adopting Topic 606 The following tables compare the select reported consolidated statements of operations and cash flows line items to the amounts had the previous guidance been in effect (in thousands): Consolidated Statements of Operations and Comprehensive Loss Year ended December 31, 2019 Year ended December 31, 2018 As Reported Balances Without Adoption of Topic 606 Effect of Change Higher/(Lower) As Reported Balances Without Adoption of Topic 606 Effect of Change Higher/(Lower) Recurring and other revenue $ 1,155,981 $ 1,038,788 $ 117,193 $ 1,050,441 $ 950,661 $ 99,780 Service and other sales revenue — 66,542 (66,542 ) — 46,177 (46,177 ) Activation fees — 8,117 (8,117 ) — 9,705 (9,705 ) Total revenues 1,155,981 1,113,447 42,534 1,050,441 1,006,543 43,898 Operating expenses 369,285 419,041 (49,756 ) 355,813 385,672 (29,859 ) Depreciation and amortization 543,440 390,733 152,707 514,082 367,879 146,203 Loss from operations (142,117 ) (81,700 ) (60,417 ) (242,059 ) (169,613 ) (72,446 ) Income tax (benefit) expense 1,313 3,142 (1,829 ) (1,611 ) 806 (2,417 ) Net loss (395,756 ) (337,168 ) (58,588 ) (467,914 ) (397,885 ) (70,029 ) Consolidated Statements of Cashflows Year ended December 31, 2019 Year ended December 31, 2018 As Reported Balances Without Adoption of Topic 606 Effect of Change As Reported Balances Without Adoption of Topic 606 Effect of Change Cash flows from operating activities: Net loss $ (395,756 ) $ (337,168 ) $ (58,588 ) $ (467,914 ) $ (397,885 ) $ (70,029 ) Adjustments to reconcile net loss to net cash used in operating activities: Amortization of capitalized contract costs 437,285 — 437,285 398,174 — 398,174 Amortization of subscriber acquisition costs — 284,574 (284,574 ) — 251,971 (251,971 ) Changes in operating assets and liabilities: Capitalized contract costs – deferred contract costs (533,504 ) — (533,504 ) (499,252 ) — (499,252 ) Subscriber acquisition costs – deferred contract costs — (483,748 ) 483,748 — (469,393 ) 469,393 Accrued expenses and other current liabilities 24,899 26,727 (1,828 ) 91,469 93,886 (2,417 ) Deferred revenue 128,624 171,163 (42,539 ) 172,905 216,803 (43,898 ) Net cash used in operating activities $ (221,592 ) $ (221,592 ) $ — $ (220,499 ) $ (220,499 ) $ — Timing of Revenue Recognition The Company previously recognized certain service and other sales revenue when the Services were provided or when title to Products sold transferred to the subscriber. Revenue from the sale of Products that were not part of the service offering (i.e., those Products sold subsequent to the date of the initial installation) were also generally recognized upon delivery of Products. Under the new standard, the Company considers Products, related installation, and its proprietary back-end cloud platform software and services an integrated system that allows the Company’s subscribers to monitor, control and protect their homes. These Smart Home Services are accounted for as a single performance obligation that is recognized over the subscriber’s contract term. Accordingly, the Company now defers a larger portion of certain Smart Home Services revenue, as prior to the adoption of Topic 606 certain of this revenue was recognized at the time services were provided or upon delivery. The Company previously amortized deferred revenues related to sales of Products and activation fees on subscriber contracts over the expected life of the customer, which was 15 years using a 240% declining balance method. Under the new standard, revenues related to sales of Products and activation fees are included in the transaction price allocated to the single Smart Home Service performance obligation and recognized straight-line over the subscriber’s contract term, which is generally three to five years. Capitalized Contract Costs Capitalized contract costs generally include commissions, other compensation and related costs incurred directly for the generation and installation of new or modified subscriber contracts, as well as the cost of Products installed in the subscriber's home at the commencement or modification of the contract. The Company previously deferred and amortized these costs for new subscriber contracts in the same manner as deferred revenue and generally expensed all costs associated with modified subscriber contracts. Under the new standard, the Company defers and amortizes these costs for new or modified subscriber contracts on a straight-line basis over the expected period of benefit of five years.

Receivables [Abstract]
Retail Installment Contract Receivables	Retail Installment Contract Receivables Certain subscribers have the option to purchase Products under a RIC, payable over either 42 or 60 months. Short-term RIC receivables are recorded in accounts and notes receivable, net and long-term RIC receivables are recorded in long-term notes receivables and other assets, net in the consolidated balance sheets. The following table summarizes the RIC receivables (in thousands): December 31, 2019 December 31, 2018 RIC receivables, gross $ 192,058 $ 175,250 RIC Discount (59,513 ) (34,163 ) RIC receivables, net $ 132,545 $ 141,087 Classified on the consolidated balance sheets as: Accounts and notes receivable, net $ 43,733 $ 32,185 Long-term notes receivables and other assets, net 88,812 108,902 RIC receivables, net $ 132,545 $ 141,087 The changes in the Company’s RIC Discount were as follows (in thousands): For the Years Ended December 31, 2019 December 31, 2018 RIC Discount, beginning of period $ 34,163 $ 36,048 Write-offs, net of recoveries (21,392 ) (26,360 ) Change in RIC Discount on short-term and long-term RIC receivables 46,742 24,475 RIC Discount, end of period $ 59,513 $ 34,163 During year ended December 31, 2019 , 2018 and 2017 , the amount of RIC imputed interest income recognized in recurring and other revenue was $13.6 million , $14.9 million and $7.3 million , respectively. Change in Accounting Estimate in 2019 RIC receivables are recorded at their present value, net of the RIC Discount. The Company records the RIC Discount as an adjustment to deferred revenue and as an adjustment to the face amount of the related receivable. The RIC Discount considers a number of factors, including collection experience, credit quality of the subscriber base and other qualitative considerations such as macro-economic factors. In the third quarter of 2019, with over two years of RIC customer history, the Company believed that it had sufficient data and experience from RIC receivables to reevaluate the remaining RIC Discount. The Company determined that actual RIC write-offs were trending higher than the expected write-offs used in the original estimates. Therefore, the Company determined that it was necessary to adjust the remaining RIC Discount balance primarily associated with subscribers originated in 2017 and 2018, to reflect the new estimate of the present value of cash expected to be collected over the remaining contractual periods. In accordance with this change in accounting estimate, in the third quarter of 2019 the Company increased the RIC Discount and recognized an adjustment to revenue to record the proportional amount related to performance obligations that have already been delivered and the remaining amount (related to undelivered performance obligations) to deferred revenue. The Company recorded a total increase to the RIC Discount of $26.6 million , with a decrease to deferred revenue of $17.5 million and a decrease to recurring and other revenue of $9.1 million . The decrease to revenue resulted in a corresponding increase to net loss for the year ended December 31, 2019.

The 2022 private placement notes are secured, on a pari passu basis, by the collateral securing obligations under the 2022 private placement notes, the 2022 notes (as defined below), the 2024 notes (as defined below) and the revolving credit facilities and the Term Loan (as defined below), in all cases, subject to certain exceptions and permitted liens. 2022 Notes As of December 31, 2019 , APX had $900.0 million outstanding aggregate principal amount of 7.875% senior secured notes due 2022 (the “2022 notes”). 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 2022 private placement notes, the 2024 notes (as defined below), the revolving credit facilities and the Term Loan, in all cases, subject to certain exceptions and permitted liens. 2023 Notes As of December 31, 2019 , APX had $400.0 million outstanding aggregate principal amount of the 7.625% senior notes due 2023 (the “2023 notes”) with a maturity date of September 1, 2023. 2024 Notes In May 2019, APX issued $225.0 million outstanding aggregate principal amount of 8.5% senior secured notes due 2024 (the “2024 notes” and, together with the 2020 notes, the 2022 notes, the 2022 private placement notes and the 2023 notes the “Notes”). The net proceeds from the 2024 notes offering were used to redeem $225.0 million aggregate principal amount of our 2020 notes, and to pay the related accrued interest and to pay all fees and expenses related thereto. The 2024 notes will mature on November 1, 2024, unless, under “Springing Maturity” provisions, (1) on September 1, 2020 (the 91st day prior to the maturity of the 2020 notes) more than an aggregate principal amount of $275.0 million of such 2020 notes remain outstanding or have not been refinanced as permitted under the note purchase agreement for the 2020 notes, in which case the 2024 notes will mature on September 1, 2020 or (2) on June 1, 2023 (the 91st day prior to the maturity of the 2023 notes) more than an aggregate principal amount of $125.0 million of such 2023 notes remain outstanding or have not been refinanced as permitted under the note purchase agreement for the 2023 notes, in which case the 2024 Notes will mature on June 1, 2023.

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 the Company 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 is 2.0% per annum and (b) under the Series B Revolving Commitments of approximately $21.2 million was 3.0% and (2)(a) the applicable margin for LIBOR rate-based borrowings (a) under the Series A 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 Series D Revolving Commitments of $15.4 million expired effective April 1, 2019 and the principal amount outstanding under the revolving credit facility will be due and payable in full with respect to the extended commitments under the Series A Revolving Credit Facility and Series B Revolving Credit Facility on March 31, 2021, unless, under “Springing Maturity” provisions, on September 1, 2020 (the 91st day prior to the maturity of the 2020 notes) more than an aggregate principal amount of $250.0 million of such 2020 notes remain outstanding or have not been refinanced as permitted under note purchase agreement for the 2020 notes, in which case the principal amount outstanding under the revolving credit facility will mature on September 1, 2020. As of December 31, 2019 there was $245.0 million outstanding borrowings under the revolving credit facility. As of December 31, 2018 , there was no outstanding borrowings under the revolving credit facility. As of December 31, 2019 , the Company had $32.1 million of availability under the revolving credit facility (after giving effect to $11.1 million of outstanding letters of credit and $245.0 million of borrowings). Guarantees All of the obligations under the credit agreement governing the revolving credit facility, the credit agreement governing the Term Loan and the debt agreements governing the Notes are guaranteed by APX Group Holdings, Inc. and each of APX Group, Inc.'s existing and future material wholly-owned U.S. restricted subsidiaries. However, such subsidiaries shall only be required to guarantee the obligations under the debt agreements governing the Notes for so long as such entities guarantee the obligations under the revolving credit facility, the credit agreement governing the Term Loan or the Company's other indebtedness.

The Term Loan is floating-rate debt and approximates the carrying value as interest accrues at floating rates based on market rates. Derivative Financial Instruments Under the Consumer Financing Program, the Company pays a monthly fee to third-party financing providers based on either the average daily outstanding balance of the loans or the number of outstanding loans depending on third-party financing provider. The Company also 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 income, net in the Consolidated Statement of Operations. The following represent the contractual obligations with the third-party financing providers under the Consumer Financing Program that are components of the derivative: • The Company pays either a monthly fee based on the average daily outstanding balance of the loans, or the number of outstanding loans, depending on the third-party financing provider • 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 The derivative is classified as a Level 3 instrument. The derivative positions are valued using a discounted cash flow model, with inputs consisting of available market data, such as market yield discount rates, as well as unobservable internally derived assumptions, such as collateral prepayment rates, collateral default rates and loss severity rates. These derivatives are priced quarterly using a credit valuation adjustment methodology. In summary, the fair value represents an estimate of the present value of the cash flows the Company will be obligated to pay to the third-party financing provider for each component of the derivative. The following table summarizes the fair value and the notional amount of the Company’s outstanding derivative instrument as of December 31, 2019 and 2018 (in thousands): December 31, 2019 2018 Consumer Financing Program Contractual Obligations: Fair value $ 136,863 $ 117,620 Notional amount 534,560 368,708 Classified on the consolidated balance sheets as: Accrued expenses and other current liabilities 80,366 67,710 Other long-term obligations 56,497 49,910 Total Consumer Financing Program Contractual Obligation $ 136,863 $ 117,620 Changes in Level 3 Fair Value Measurements The following table summarizes the change in the fair value of the Level 3 outstanding derivative instrument for the years ended December 31, 2019 and 2018 (in thousands): December 31, 2019 2018 Balance, beginning of period $ 117,620 $ 46,496 Additions 94,592 93,095 Settlements (70,213 ) (34,587 ) (Gains) losses included in earnings (5,136 ) 12,616 Balance, end of period $ 136,863 $ 117,620

The Company completed the majority of these cost reduction initiatives in the second and third quarters of 2018, with the remainder by the end of 2018. In addition to resulting in meaningful cost reductions, the Company’s initiatives are expected to streamline operations, focus engineering and innovation and provide a better focus on driving customer satisfaction. As part of these initiatives, the Company and Best Buy agreed in principle to end the co-branded Best Buy Smart Home by Vivint arrangement ("Best Buy Agreement"), which resulted in the elimination of in-store sales positions. In addition, the Company eliminated other general and administrative positions. These actions resulted in one-time cash employee severance and termination benefits expenses of $4.7 million during the year ended December 31, 2018. The Company formally terminated its relationship with Best Buy in December 2018 and agreed to pay a termination fee of $5.5 million . The difference between the termination fee and all previously recorded liabilities relating to the Company's Best Buy Agreement was recorded as a reduction to capitalized contract costs. The following table presents accrued restructuring activity for the years ended December 31, 2019 and 2018 .

As a result of the spin-off, the Company's additional paid-in capital was decreased by the net assets of Wireless of $4.8 million , as of the effective date of the spin-off. The spin-off does not represent a strategic shift that has (or will have) a major effect on the Company's operations and financial results. The results of Wireless are reflected in the Company's consolidated financial statement up through July 31, 2019.

State net operating loss carryforwards expire over different periods and some have already begun to expire. The Company had United States research and development credits of approximately $41,000 at December 31, 2019 , and December 31, 2018 , which begin to expire in 2030 . Canadian net operating loss carryforwards will begin to expire in 2029 . Realization of the Company’s federal and state net operating loss carryforwards and tax credits is dependent on generating sufficient taxable income prior to their expiration. Although a portion of these net operating loss carryforwards may be subject to the provisions of Internal Revenue Code Section 382, the Company has not performed a formal study to determine the amount of any limitation. The use of the net operating loss carryforwards may have additional limitations resulting from future ownership changes or other factors under Section 382 of the Internal Revenue Code. On December 22, 2017, Congress enacted the Tax Act, which made significant changes to U.S. federal income tax laws, including reducing the corporate rate from 35% to 21% effective January 1, 2018. The Tax Act included a Global Intangible Low-Taxed Income ("GILTI") provision which introduced a new tax on foreign income in excess of a deemed return on tangible business property of foreign subsidiaries. The GILTI provisions of the Tax Act became effective for the Company during 2018 and it elected to account for it in the period incurred (the "period cost method"). At December 31, 2019 and 2018 , the Company recorded a valuation allowance against its U.S. federal and state net deferred tax assets as it believes it is more likely than not that these benefits will not be realized. Significant judgment is required in determining the Company’s provision for income taxes, recording valuation allowances against net deferred tax assets and evaluating the Company’s uncertain tax positions. The Company has considered and weighed the available evidence, both positive and negative, to determine whether it is more likely than not that some portion, or all, of the deferred tax assets will not be realized. Based on available information, management does not believe it is more likely than not that all of its deferred tax assets will be utilized. The Company recorded a valuation allowance for U.S. net deferred tax assets of approximately $566.4 million and $467.7 million at December 31, 2019 and 2018 , respectively. As of December 31, 2019 , the Company's income tax returns for the tax years 2014 and later, remain subject to examination by the Internal Revenue Service and various state taxing authorities.

Share-based Payment Arrangement [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 the Investors, 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”). As of December 31, 2019 , a total of 78,401,126 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 issued to the Company’s Chief Executive Officer and President. In June 2018, the Incentive Units and SARs (defined below) vesting terms were modified (“Modification”). Prior to the Modification, the Incentive Units were subject to time-based and performance-based vesting conditions, with (1) one-third subject to ratable time-based vesting over a five year period from the applicable vesting reference date and (2) two-thirds subject to the achievement of certain investment return thresholds by The Blackstone Group Inc. and its affiliates (“Blackstone”). Pursuant to the Modification the Incentive Units are subject to time-based and performance-based vesting conditions, with (1) one-third subject to ratable time-based vesting over a five year period from the applicable vesting reference date, (2) one-third subject to the achievement of certain investment return thresholds by Blackstone and (3) one-third subject to ratable time-based vesting over a five year period from June 2018 for those granted prior to the modification or the applicable vesting reference date for those granted on or following the Modification. 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 the event of a change of control, all outstanding Incentive Units with time-based vesting conditions will become fully vested and exercisable. The fair value of stock-based awards is measured at the grant date, or the Modification 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 rate between 0.61% and 2.61% . A summary of the Incentive Unit activity for the years ended December 31, 2019 and 2018 is presented below: Incentive Units Weighted Average Exercise Price Per Share Weighted Average Remaining Contractual Life (Years) Aggregate Intrinsic Value (in millions) Outstanding, December 31, 2017 85,812,836 $ 1.19 5.81 $ — Forfeited (450,000 ) 1.93 Outstanding, December 31, 2018 85,362,836 1.19 5.81 — Granted 1,000,000 1.95 Forfeited (7,961,710 ) 1.32 Outstanding, December 31, 2019 78,401,126 1.18 5.28 51.2 Unvested shares expected to vest after December 31, 2019 48,574,548 1.21 5.38 30.5 Exercisable at December 31, 2019 29,826,578 $ 1.13 5.12 $ 20.7 As of December 31, 2019 , there was $7.9 million of unrecognized compensation expense related to outstanding Incentive Units, which will be recognized over a weighted-average period of 3.41 years . As of each December 31, 2019 and 2018 , the weighted average grant date fair value per share of the outstanding incentive units was $0.36 . Stock Appreciation Rights The Company’s subsidiary, Vivint Group, Inc. (“Vivint Group”), has awarded Stock Appreciation Rights (“SARs”) to various levels of key employees and board members, 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 and/or its direct or indirect parents. Prior to the Modification in June 2018, the SARs were subject to time-based and performance-based vesting conditions, with (1) one-third subject to ratable time-based vesting over a five year period from the applicable vesting reference date and (2) two-thirds subject to the achievement of certain investment return thresholds by Blackstone. Pursuant to the Modification the Incentive Units are subject to time-based and performance-based vesting conditions, with (1) one-third subject to ratable time-based vesting over a five year period from the applicable vesting reference date, (2) one-third subject to the achievement of certain investment return thresholds by Blackstone and (3) one-third subject to ratable time-based vesting over a five year period from June 2018 for those granted prior to the Modification or the applicable vesting reference date for those granted on or following the Modification. 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, 41,700,249 SARs were outstanding as of December 31, 2019 . In addition, 53,621,891 SARs have been set aside for funding incentive compensation pools pursuant to long-term sales and installation employee incentive plans established by the Company. In the event of a change of control, all outstanding SARs with time-based vesting conditions will become fully vested and exercisable. The Company expects to settle SARs through issuance of common stock. The fair value of the Vivint Group awards is measured at the grant date, or the Modification 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 6.50 years ; and risk-free rates between 0.61% and 2.61% . 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. A summary of the Vivint Group SAR activity for the years ended December 31, 2019 and 2018 is presented below: Stock Appreciation Rights Weighted Average Exercise Price Per Share Weighted Average Remaining Contractual Life (Years) Aggregate Intrinsic Value (in millions) Outstanding, December 31, 2017 32,754,290 $ 1.26 9.21 $ — Granted 14,630,000 1.79 Forfeited (9,255,137 ) 1.31 Exercised (117,274 ) 0.89 Outstanding, December 31, 2018 38,011,879 1.46 8.07 — Granted 10,772,000 1.95 Forfeited (5,584,582 ) 1.55 Exercised (1,499,048 ) 0.89 Outstanding, December 31, 2019 41,700,249 1.57 7.86 0.9 Unvested shares expected to vest after December 31, 2019 33,649,333 1.63 8.07 0.5 Exercisable at December 31, 2019 8,050,916 $ 1.32 7.01 $ 0.4 As of December 31, 2019 , there was $6.2 million of unrecognized compensation expense related to outstanding Vivint awards, which will be recognized over a weighted-average period of 3.55 years . As of December 31, 2019 and 2018 , the weighted average grant date fair value per share of the outstanding SARs was $0.30 and $0.23 , respectively. Restricted Stock Units In March 2019 and June 2018, the Company’s subsidiary, Vivint Group, awarded 236,111 and 360,000 Restricted Stock Units (“RSUs”), respectively, to certain board members, pursuant to an omnibus incentive plan. The purpose of the RSUs is to compensate board members for their board service and align their interests of those of the Company's shareholders. The RSUs are subject to a three year time-based ratable vesting period. 397,407 RSUs are expected to vest after December 31, 2019 and 198,704 are exercisable at December 31, 2019 . In the event of a change of control, all outstanding RSUs will become fully vested. The fair value of the RSU awards, representing the estimated equity value per share of Vivint Group at the grant date, is recognized as expense over the requisite service period. The fair values are determined using management’s financial projections and available market data at the time of issuance. The grant date fair value per share of the outstanding RSUs was $1.08 for the March 2019 issuance and $0.48 for the June 2018 issuance. As of December 31, 2019 , there was $0.2 million of unrecognized compensation expense related to outstanding RSUs, which will be recognized over a period of 1.62 years . Stock-based compensation expense in connection with all stock-based awards for the years ended December 31, 2019 , 2018 and 2017 is allocated as follows (in thousands): Year ended December 31, 2019 2018 2017 Operating expenses $ 320 $ 129 $ 65 Selling expenses 508 285 217 General and administrative expenses 3,413 2,091 1,313 Total stock-based compensation $ 4,241 $ 2,505 $ 1,595 Capital Contribution During each year end December 31, 2019 and 2018, Parent contributed $4.7 million to the Company as capital contributions.

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 these 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, and 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 addition, from time to time the Company is subject to examinations, investigations and/or enforcement actions by federal and state licensing and regulatory agencies and may face the risk of penalties for violation of financial services, consumer protections and other applicable laws and regulations. For example, in 2019, the Company received a subpoena in connection with an investigation by the U.S. Department of Justice (“DOJ”) concerning potential violations of the Financial Institutions Reform, Recovery and Enforcement Act (“FIRREA”). The Company also has received a civil investigative demand from the staff of the Federal Trade Commission (“FTC”) concerning potential violations of the Fair Credit Reporting Act (“FCRA”) and the “Red Flags Rule” thereunder, and the Federal Trade Commission Act (“FTC Act”). 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 $1.8 million and $2.5 million as of December 31, 2019 and 2018 , respectively. In conjunction with one of the settlements, the Company is obligated to pay certain future royalties, based on sales of future Products. During the year ended December 31, 2017 the Company accrued $10.0 million related to the settlement of litigation with ADT Inc. included in accounts payable on the consolidated balance sheets. The Company paid the full amount in early 2018. Operating Leases The Company leases office and warehouse space, certain equipment, 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. Total rent expense for all operating leases for the years ended December 31, 2018 and 2017 was $16.5 million and $17.0 million , respectively. See Note 14 "Leases" for additional information related to the impact of adopting Topic 842. Capital Leases The Company also enters into certain capital leases with expiration dates through May 2022 . On an ongoing basis, the Company enters into vehicle lease agreements under a Fleet Lease Agreement. The lease agreements are typically 36 to 48 month leases for each vehicle. As of December 31, 2018 , the capital lease obligation balance was $13.3 million . See Note 14 "Leases" for additional information related to the impact of adopting Topic 842. Spectrum Licenses During the year ended December 31, 2016, Vivint Wireless, Inc. (“Vivint Wireless”), an indirect wholly owned subsidiary of the Company, entered into leasing agreements with Nextlink Wireless, LLC (“Nextlink”) for designated radio frequency spectrum in 40 mid-sized metropolitan markets. In December 2017, Vivint Wireless entered into a Termination Agreement with Verizon Communications Inc. (“Verizon”) pursuant to which the parties agreed, among other things, to terminate certain spectrum leases, including the 40 aforementioned leasing agreements, between Vivint Wireless and Nextlink, a subsidiary of Verizon, in exchange for cash consideration. In January 2018, the Company consummated the transactions contemplated by the Termination Agreement with Verizon. See Note 8 for further discussion. In addition to the commitments mentioned above, the Company had other purchase obligations of $48.6 million as of December 31, 2019 that consisted of commitments related to software licenses, marketing activities, and other goods and services.

Related Party Transactions [Abstract]
Related Party Transactions	Related Party Transactions Transactions with Vivint Solar The Company is a party to a number of agreements with its sister company, Vivint Solar, Inc. (“Solar”). Historically, some of those agreements related to Solar’s use of certain of the Company’s information technology and infrastructure services; however, Solar stopped using such services in July 2017. In August 2017, the Company entered into a sales dealer agreement with Solar, pursuant to which each company agreed to act as a non-exclusive dealer for the other party to market, promote and sell each other’s products. During the year ended December 31, 2019 , 2018 and 2017 the Company charged $9.2 million , $17.3 million and $2.8 million , respectively of net expenses to Solar in connection with these agreements and was included in selling expenses in the accompanying consolidated statement of operations. The balance due from Solar in connection with these agreements and other expenses paid on Solar’s behalf was $2.2 million at December 31, 2019 , and is included in prepaid expenses and other current assets in the accompanying consolidated balance sheets. As of December 31, 2018 the balance due from Solar was immaterial. Other Related-party Transactions The Company incurred additional expenses during the years ended December 31, 2019 , 2018 and 2017 , of approximately $2.5 million , $2.7 million , $3.5 million , respectively, for other related-party transactions including contributions to the charitable organization Vivint Gives Back, legal fees, and other services. These expenses were included in selling and general and administrative expenses in the accompanying consolidated statement of operations. Accrued expenses and other current liabilities at December 31, 2019 and 2018 included net payables associated with these related-party transactions of $1.0 million and $0.2 million , respectively. On July 31, 2019, in an effort to deliver additional cost savings and cash-flow improvements, the Company completed a spin-off of Wireless, its wireless internet business. Associated with the spin-off, the Company and Wireless entered into a Transition Service Agreement (“TSA”) According to the TSA, Vivint performs specified services for Wireless, including human resources, information technology, and facilities. The Company invoices Wireless on a monthly basis for these agreed upon services. Additionally, Vivint cross charges Wireless for items not included in the TSA but that are paid for by Vivint on behalf of Wireless. Transactions associated with these services were $ 1.3 million for the year ended December 31, 2019 . The Company recorded a reserve against the full balance due from Wireless in connection with the TSA as of December 31, 2019. On November 16, 2012, the Company was acquired by an investor group comprised of certain investment funds affiliated with Blackstone Capital Partners VI L.P., and certain co-investors and management investors through certain mergers and related reorganization transactions (collectively, the “Transaction”). In connection with the Transaction, the Company engaged Blackstone Management Partners L.L.C. (“BMP”) to provide monitoring, advisory and consulting services on an ongoing basis. In consideration for these services, the Company agreed to pay an annual monitoring fee equal to the greater of (i) a minimum base fee of $2.7 million subject to adjustments if the Company engages in a business combination or disposition that is deemed significant and (ii) the amount of the monitoring fee paid in respect of the immediately preceding fiscal year, without regard to any post-fiscal year “true-up” adjustments as determined by the agreement. The Company incurred expenses for such services of approximately $5.6 million , $4.1 million and $3.5 million during the years ended December 31, 2019 , 2018 and 2017 , respectively and was included in general and administrative expense in the accompanying consolidated statement of operations. Accrued expenses and other current liabilities at December 31, 2018 included a liability of $4.8 million to BMP related to the monitoring fee. Under the support and services agreement, the Company also engaged BMP to arrange for Blackstone’s portfolio operations group to provide support services customarily provided by Blackstone’s portfolio operations group to Blackstone’s private equity portfolio companies of a type and amount determined by such portfolio services group to be warranted and appropriate. BMP will invoice the Company for such services based on the time spent by the relevant personnel providing such services during the applicable period but in no event shall the Company be obligated to pay more than $1.5 million during any calendar year. During the years ended December 31, 2019 , 2018 and 2017 the Company incurred no costs associated with such services. Additionally, during the year ended December 31, 2019 the Company agreed to reimburse Blackstone for $1.8 million of certain other fees incurred by Blackstone for activities related to the Company and was included in general and administrative expenses in the accompanying consolidated statement of operations. The full amount was included in accrued expenses and other current liabilities as of December 31, 2019 . An affiliate of Blackstone participated as one of the arrangers in the Term Loan in September 2018 and as one of the initial purchasers in connection with the offering of the 2024 Notes in May 2019 and received approximately $1.2 million of total fees associated with these transactions. During the year ended December 31, 2017, Blackstone Advisory Partners L.P., an affiliate of Blackstone participated as one of the initial purchasers of the 2022 notes in the February 2017 issuance and the 2023 notes in the August 2017 issuance and received fees at the time of closing of such issuances aggregating approximately $0.6 million .

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The Company has prepared the accompanying consolidated financial statements pursuant to generally accepted accounting principles in the United States (“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.
Retail Installment Contract Receivables	Retail Installment Contract Receivables For subscribers that enter into a RIC to finance the purchase of Products and related installation, the Company records a receivable for the amount financed. Gross RIC receivables are reduced for (i) expected write-offs of uncollectible balances over the term of the RIC and (ii) a present value discount of the expected cash flows using a risk adjusted market interest rate (together, the “RIC Discount”). Therefore, the RIC receivables equal the present value of the expected cash flows to be received by the Company over the term of the RIC. At the time of installation, the Company records a long-term note receivable within long-term notes receivables and other assets, net on the 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 consolidated balance sheets. The billed amounts of notes receivables are included in accounts receivable within accounts and notes receivable, net on the 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 risk adjusted interest rate considers a number of factors, including credit quality of the subscriber base and other qualitative considerations such as macro-economic factors. The imputed interest income is recognized over the term of the RIC contract as recurring and other revenue on the consolidated statements of operations. When the Company determines that there are RIC receivables that have become uncollectible, it records an adjustment to the RIC Discount and reduces the related note receivable balance. On a regular basis, the Company also assesses the level of the RIC Discount balance based on historical RIC write-off trends and adjusts the balance, if necessary. 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.
Revenue	Vivint Flex Pay The Vivint Flex Pay plan (“Vivint Flex Pay”) became the Company’s primary sales model beginning in March 2017. Under Vivint Flex Pay, customers pay separately for the products (including control panel, security peripheral equipment, smart home equipment, and related installation) (“Products”) and Vivint’s smart home and security services (“Services”). The customer has the following three ways to pay for the Products: (1) qualified customers in the United States may finance the purchase of Products through a third-party financing providers (“Consumer Financing Program”) (2) the Company offers to some 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 (3) customers may purchase the Products at the outset of the service contract by check, automatic clearing house payments (“ACH”), credit or debit card. Although customers pay separately for Products and Services under the Vivint Flex Pay plan, the Company has determined that the shift in its sales model does not change the Company's conclusion that the sale of Products and Services are one single performance obligation. 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. Under the Consumer Financing Program, qualified customers are eligible for loans provided by third-party financing providers of up to $4,000 . The annual percentage rates on these loans range between 0% and 9.99% , based on the customer's credit quality, and are either installment or revolving loans with a 42 or 60 month term. For certain third-party provider loans, the Company pays a monthly fee based on either the average daily outstanding balance of the loans or the number of outstanding loans, depending on the third-party financing provider and the Company shares liability for credit losses, with the Company being responsible for between 5% and 100% of lost principal balances. Additionally, the Company is responsible for reimbursing certain third-party financing providers for credit card transaction fees associated with the loans. Because of the nature of these provisions, the Company records a derivative liability at its fair value when the third-party financing provider originates loans to customers, which reduces the amount of estimated revenue recognized on the provision of the services. The derivative liability is reduced as payments are made by the Company to the third-party financing provider. Subsequent changes to the fair value of the derivative liability are realized through other expenses (income), net in the Consolidated Statement of Operations. (See Note 9 ). For other third-party loans, the Company receives net proceeds (net of fees and expected losses) for which the Company has no further obligation to the third-party. The Company records these net proceeds to deferred revenue. Revenue Recognition The Company offers its customers smart home services combining Products, including a proprietary control panel, door and window sensors, door locks, security cameras and smoke alarms; installation; and a proprietary back-end cloud platform software and Services. These together create an integrated system that allows the Company’s customers to monitor, control and protect their home (“Smart Home Services”). The Company’s customers are buying this integrated system that provides them with these Smart Home Services. The number and type of Products purchased by a customer depends on their desired functionality. Because the Products 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 concluded that installed Products, related installation and Services contracted for by the customer are generally not distinct within the context of the contract and, therefore, constitute a single, combined performance obligation. Revenues for this single, combined performance obligation are recognized on a straight-line basis over the customer’s contract term, which is the period in which the parties to the contract have enforceable rights and obligations. The Company has determined that certain contracts that do not require a long-term commitment for monitoring services by the customer contain a material right to renew the contract, because the customer does not have to purchase Products upon renewal. Proceeds allocated to the material right are recognized over the period benefit, which is generally three years . The majority of the Company’s subscription contracts are between three and five years in length and are non-cancelable. These contracts with customers generally convert into month-to-month agreements at the end of the initial term, and some customer contracts are month-to-month from inception. Payment for recurring monitoring and other Smart Home Services is generally due in advance on a monthly basis. Sales of Products and other one-time fees such as service fees or installation fees are invoiced to the customer at the time of sale. Revenues for wireless internet service that were provided by Vivint Wireless Inc. (“Wireless Internet” or “Wireless”) and any Products or Services that are considered separate performance obligations are recognized when those Products or Services are delivered. Taxes collected from customers and remitted to governmental authorities are not included in revenue. Payments received or amounts billed in advance of revenue recognition are reported as deferred revenue. Deferred Revenue The Company's deferred revenues primarily consist of amounts for sales (including upfront proceeds) of Smart Home Services. Deferred revenues are recognized over the term of the related performance obligation, which is generally three to five years .
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 consolidated balance sheets. Accounts receivable totaled $20.5 million and $16.5 million and December 31, 2019 and 2018 , respectively net of the allowance for doubtful accounts of $8.1 million and $5.6 million at December 31, 2019 and 2018 , 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. The provision for doubtful accounts is included in general and administrative expenses in the accompanying consolidated statements of operations and totaled $25.0 million and $19.4 million for the years ended December 31, 2019 and 2018 , respectively.
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 10 ).
Principles of Consolidation	Principles of Consolidation 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.
Capitalized Contract Costs	Capitalized Contract Costs Capitalized contract costs represent the costs directly related and incremental to the origination of new contracts, modification of existing contracts or to the fulfillment of the related subscriber contracts. These include commissions, other compensation and related costs incurred directly for the origination and installation of new or upgraded customer contracts, as well as the cost of Products installed in the customer home at the commencement or modification of the contract. The Company calculates amortization by accumulating all deferred contract costs into separate portfolios based on the initial month of service and amortizes those deferred contract costs on a straight-line basis over the expected period of benefit that the Company has determined to be five years , consistent with the pattern in which the Company provides services to its customers. The Company believes this pattern of amortization appropriately reduces the carrying value of the capitalized contract costs over time to reflect the decline in the value of the assets as the remaining period of benefit for each monthly portfolio of contracts decreases. The period of benefit of five years is longer than a typical contract term because of anticipated contract renewals. The Company applies this period of benefit to its entire portfolio of contracts. The Company updates its estimate of the period of benefit periodically and whenever events or circumstances indicate that the period of benefit could change significantly. Such changes, if any, are accounted for prospectively as a change in estimate. Amortization of capitalized contract costs is included in “Depreciation and Amortization” on the consolidated statements of operations. The carrying amount of the capitalized contract costs is periodically reviewed for impairment. In performing this review, the Company considers whether the carrying amount of the capitalized contract costs will be recovered. In estimating the amount of consideration the Company expects to receive in the future related to capitalized contract costs, the Company considers factors such as attrition rates, economic factors, and industry developments, among other factors. If it is determined that capitalized contract costs are impaired, an impairment loss is recognized for the amount by which the carrying amount of the capitalized contract costs and the anticipated costs that relate directly to providing the future services exceed the consideration that has been received and that is expected to be received in the future. Contract costs not directly related and incremental to the origination of new contracts, modification of existing contracts or to the fulfillment of the related subscriber contracts are expensed as incurred. These costs include those associated with housing, marketing and recruiting, non-direct lead generation costs, certain portions of sales commissions and residuals, overhead and other costs considered not directly and specifically tied to the origination of a particular subscriber. On the consolidated statement of cash flows, capitalized contract costs are classified as operating activities and reported as “Capitalized contract costs - deferred contract costs” as these assets represent deferred costs associated with subscriber 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. Inventories sold to customers as part of a smart home and security system are generally capitalized as capitalized contract costs. The Company adjusts the inventories balance based on anticipated obsolescence, usage and historical write-offs.
Property, Plant and Equipment and Long-lived Assets	Property, Plant and Equipment and Long-lived Assets 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 finance 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 2 to 10 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 reviews long-lived assets, including property, plant and equipment, capitalized contract costs, and definite-lived intangibles for impairment when events or changes in circumstances indicate that the carrying amount may not be recoverable. The Company considers whether or not indicators of impairment exist on a regular basis and as part of each quarterly and annual financial statement close process. Factors the Company considers in determining whether or not indicators of impairment exist include market factors and patterns of customer attrition. If indicators of impairment are identified, the Company estimates the fair value of the assets. An impairment loss is recognized if the carrying amount of a long-lived asset is not recoverable and exceeds its fair value. The Company conducts an indefinite-lived intangible impairment analysis annually as of October 1, and as necessary if changes in facts and circumstances indicate that the fair value of the Company’s indefinite-lived intangibles may be less than the carrying amount. When indicators of impairment do not exist and certain accounting criteria are met, the Company is able to evaluate indefinite-lived intangible impairment using a qualitative approach. When necessary, the Company’s quantitative impairment test consists of two steps. The first step requires that the Company compare the estimated fair value of its indefinite-lived intangibles to the carrying value. If the fair value is greater than the carrying value, the intangibles are not considered to be impaired and no further testing is required. If the fair value is less than the carrying value, an impairment loss in an amount equal to the difference is recorded.
Wireless Spectrum Licenses	Wireless Spectrum Licenses The Company had capitalized as an intangible asset wireless spectrum licenses that were acquired from third parties. 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 determined that the wireless spectrum licenses met the definition of indefinite-lived intangible assets because the licenses were able to be renewed periodically for a nominal fee, provided that the Company continued to meet the service and geographic coverage provisions. In January 2018, the Company terminated the wireless spectrum licenses for cash consideration.
Leases	Leases Effective January 1, 2019 the Company accounts for leases under Topic 842 (see Recently Adopted Accounting Standards below). Under Topic 842, the Company determines if an arrangement is a lease at inception. Lease right-of-use (“ROU”) assets represent the Company's right to use an underlying asset for the lease term and lease liabilities represent the obligation to make lease payments arising from the lease. Lease ROU assets and liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. In determining the present value of lease payments, the Company uses the implicit rate when available. When implicit rates are not available, the Company uses an incremental borrowing rate based on the information available at commencement date. The lease ROU asset also includes any lease payments made and is reduced by lease incentives. Lease expense for lease payments is recognized on a straight-line basis over the lease term. The Company does not record lease ROU assets and liabilities for leases with terms of 12 months or less. Leases are classified as either operating or finance at lease inception. Operating lease assets and liabilities and finance lease liabilities are stated separately on the consolidated balance sheets. Finance lease assets are included in property, plant and equipment, net on the consolidated balance sheets. The Company has lease agreements with lease and non-lease components. For facility type leases, the Company separates the lease and non-lease components. Generally, the Company accounts for the lease and non-lease components as a single lease component for all other class of leases. Prior to the adoption of Topic 842, the Company's leases were classified as either operating or capital leases. Capital lease liabilities were stated separately on the consolidated balance sheets and capital lease assets were included in property, plant and equipment, net on the consolidated balance sheets. Operating leases were not recognized in the balance sheet. Capital lease balances are presented on the same lines as finance lease balances for comparative prior periods in the unaudited consolidated financial statements. See Recently Adopted Accounting Standards below and note 14 "Leases" for additional information related to the impact of adopting Topic 842.
Long-term Investments	Long-term Investments The Company’s long-term investments are composed of equity securities in certain companies. As of December 31, 2018 , the Company's equity investments totaled $3.9 million . The Company did not hold any equity security investments as of December 31, 2019 . Management determines the appropriate fair value measurement of its investments at the time of purchase and reevaluates the fair value measurement at each balance sheet date. 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 equity securities are carried at fair value, with gains and losses, reported in other income or loss within the statement of operations The Company performs impairment analyses of its investments without readily determinable fair values 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, the Company evaluates impairment using a qualitative approach. Additionally, increases or decreases in the carrying amount resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer are adjusted through the statement of operations as needed.
Deferred Financing Costs	Deferred Financing Costs Certain 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 associated with obtaining APX's revolving credit facility are amortized over the amended maturity dates discussed in Note 5 . Deferred costs associated with the revolving credit facitliy reported in the accompanying consolidated balance sheets as deferred financing costs, net at December 31, 2019 and 2018 were $1.1 million and $2.1 million , net of accumulated amortization of $10.6 million and $9.6 million , respectively. Deferred financing costs included in the accompanying consolidated balance sheets within notes payable, net at December 31, 2019 and 2018 were $27.0 million and $32.4 million , net of accumulated amortization of $63.5 million and $54.6 million , respectively. Amortization expense on deferred financing costs recognized and included in interest expense in the accompanying consolidated statements of operations totaled $9.8 million , $10.4 million and $11.4 million for the years ended December 31, 2019 , 2018 and 2017 , respectively.
Residual Income Plan	Residual Income Plans 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 “Channel Partner Plan”). The Company also has a residual sales compensation plan (the “Residual Plan”) under which the Company's sales personnel (each, a “Plan Participant”) receive compensation based on the performance of the underlying contracts they create. For both the Channel Partner Plan and Residual Plan, the Company calculates the present value of the expected future residual payments and records a liability for this amount in the period the subscriber account is originated. These costs are recorded to capitalized contract costs. 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 $4.5 million and $4.5 million as of December 31, 2019 and 2018 , respectively, and the amount included in other long-term obligations was $20.7 million and $13.0 million at December 31, 2019 and 2018 , respectively.
Stock-Based Compensation	Stock-Based Compensation The Company measures compensation cost based on the grant-date fair value of the award and recognizes that cost over the requisite service period of the awards (See Note 12 ).
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, or all, 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. Changes in tax laws and rates could also affect recorded deferred tax assets and liabilities in the future. The Company records the effect of a tax rate or law change on the Company’s deferred tax assets and liabilities in the period of enactment. Future tax rate or law changes could have a material effect on the Company’s results of operations, financial condition, or cash flows (See Note 11 )
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 December 31, 2019 , approximately 88% of the Company’s installed panels were SkyControl panels, 12% were 2GIG Go!Control panels. During 2018 the Company transitioned to a new panel supplier. The loss of the Company's panel supplier could potentially impact its 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 years ended December 31, 2019 and 2018 . 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 their carrying amounts. 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. The Company’s reporting units are determined based on its current reporting structure, which as of December 31, 2019 consisted of one reporting unit. The Company found that no indicators of goodwill impairment existed during the year ended December 31, 2019 , thus a qualitative approach was used and it was determined that no impairment existed for goodwill.
Foreign Currency Translation and Other Comprehensive Income	Foreign Currency Translation and Other Comprehensive Income The functional currency of Vivint Canada, Inc. is the Canadian dollar. Accordingly, Vivint Canada, Inc. assets and liabilities are translated from their respective functional currencies into U.S. dollars at period-end rates and Vivint Canada, Inc. 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 (loss) income and shown as a separate component of equity. 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) equity as accumulated other comprehensive loss or income. When intercompany transactions are deemed to be of a short term nature, translation adjustments are required to be included in the consolidated statement of operations. The Company has determined that settlement of Vivint Canada, Inc. intercompany balances are anticipated and therefore such balances are deemed to be of a short-term nature. Translation activity included in the statements of operations in other loss, net related to intercompany balances was a gain of $3.4 million for the year ended December 31, 2019 , a loss of $7.1 million for the year ended December 31, 2018 , and a gain of $4.9 million for the year ended December 31, 2017 .
Letters of Credit	Letters of Credit As of December 31, 2019 and 2018 , the Company had $11.1 million and $13.8 million , respectively, of letters of credit issued in the ordinary course of business, all of which are undrawn.
Recent Accounting Pronouncements and Recently Adopted Accounting Standards	Recent Accounting Pronouncements In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2016-13, “Financial Instruments—Credit Losses (Topic 326)” 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 expects the adoption of ASU 2016-13 to have an impact on the accounting for accounts receivable and RICs included in accounts and notes receivable, net and long-term notes receivables and other assets, net in the balance sheets and is still evaluating the extent of such impact. Recently Adopted Accounting Standards ASU 2016-02 In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842)” 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. The Company adopted ASU 2016-02 as of January 1, 2019, utilizing the modified retrospective approach and using certain practical expedients. The adoption of the standard resulted in recording ROU assets of $75.5 million and lease liabilities of $85.9 million as of January 1, 2019. The ROU assets are lower than the lease liabilities as existing deferred rent and lease incentive liabilities were recorded against the ROU assets at adoption in accordance with the standard. The standard did not materially affect the Company's consolidated statements of operations or its consolidated statements of cash flows. The standard also resulted in a reassessment that a sale would have occurred at January 1, 2019 for the Company's build-to-suit building. As a result, the Company classifies the leasing arrangement as an operating lease. The recognition of the sale-leaseback transaction resulted in an immaterial amount recorded to opening equity. See Note 6 for additional information on the sale-leaseback transaction. See Note 14 "Leases" for additional information related to the impact of adopting this standard. ASU 2014-09 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. Topic 606 also includes Subtopic 340-40, Other Assets and Deferred Costs - Contracts with Customers, which requires the deferral of incremental costs of obtaining a contract with a customer. Collectively, the Company refers to Topic 606 and Subtopic 340-40 as the “new standard”. The Company adopted the new standard as of January 1, 2018, utilizing the modified retrospective method of transition (the cumulative catch-up transition method). Adoption of the new standard resulted in changes to the accounting policies for revenue recognition, deferred revenue, and capitalized contract costs (formerly subscriber acquisition costs). The cumulative effect of applying the new standard to all contracts with customers that were not completed as of January 1, 2018 was recorded as an adjustment to accumulated deficit as of the adoption date. The comparative information as of and for the year ended December 31, 2017 has not been adjusted and continues to be reported under Topic 605. See Note 3 "Revenue and Capitalized Contract Costs" for additional information related to the impact of adopting this standard and a discussion of the Company's updated policies related to revenue recognition and accounting for costs to obtain and fulfill a customer contract.
