Accounting Policies [Abstract]
Basis of Presentation and Significant Accounting Policies	Basis of Presentation and Significant Accounting Policies Going Concern APX Group Holdings, Inc. and subsidiaries (the “Company”) has prepared its unaudited condensed consolidated financial statements assuming that the Company will continue as a going concern. However, if the Company does not make specified debt repayments prior to September 1, 2020, certain other indebtedness will become due and payable on that date as discussed below. The Company has historically generated recurring net losses and negative cash flows from operations and may be unable to refinance its debt or make such specified debt repayments prior to September 1, 2020. These conditions raise substantial doubt about the Company’s ability to continue as a going concern. These unaudited condensed consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty. As discussed in Note 3 , certain of the Company’s debt agreements contain “springing maturity” provisions. Under the terms of these springing maturity provisions, if on September 1, 2020 more than $190.0 million aggregate principal amount under the 2020 notes remains outstanding or has not been refinanced, the 2022 notes and 2022 private placement notes will mature on September 1, 2020. If on September 1, 2020 more than $250.0 million aggregate principal amount under the 2020 notes remains outstanding or has not been refinanced, the revolving credit facility will also mature on September 1, 2020. In addition, if on September 1, 2020 more than $275.0 million aggregate principal amount under the 2020 notes remains outstanding or has not been refinanced, the Term Loan and the 2024 notes will also mature on September 1, 2020. As of September 30, 2019 , the Company had $454.3 million aggregate principal amount of the 2020 notes outstanding. As of September 30, 2019 , the Company had $2.9 million of cash and cash equivalents and $140.3 million of availability under the Company’s revolving credit facility. Management plans to use a portion of the proceeds from the Mosaic Merger to repay all of the outstanding 2020 notes, in which case the maturity dates for the debt discussed above would not accelerate to September 1, 2020 from the original maturity dates disclosed in Note 3. There is no assurance that the Mosaic Merger and the associated debt repayment will be completed as currently contemplated or at all. To the extent additional capital is not obtained through the Mosaic Merger, management will seek other forms of financing, which may include issuance of additional equity or debt or other means of timely addressing the Company’s debt obligations. There is no assurance such other forms of financing will be available. Unaudited Interim Financial Statements The accompanying interim unaudited condensed consolidated financial statements included in this Quarterly Report on Form 10-Q have been prepared by the Company without audit. The accompanying consolidated financial statements include the accounts of APX Group Holdings, Inc. and its subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation. Certain information and footnote disclosures normally included in consolidated financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) have been condensed or omitted pursuant to such rules and regulations. The information as of December 31, 2018 included in the unaudited condensed consolidated balance sheets was derived from the Company’s audited consolidated financial statements. The unaudited condensed consolidated financial statements included in this Quarterly Report on Form 10-Q were prepared on the same basis as the audited consolidated financial statements and, in the opinion of management, reflect all adjustments (all of which are considered of a normal recurring nature) considered necessary to present fairly the Company’s financial position, results of operations and cash flows for the periods and dates presented. The results of operations for the three and nine months ended September 30, 2019 are not necessarily indicative of the results that may be expected for the year ending December 31, 2019 . These unaudited condensed consolidated financial statements and notes should be read in conjunction with the Company’s audited consolidated financial statements and related notes as set forth in the Company’s Annual Report on Form 10-K/A for the fiscal year ended December 31, 2018 , as filed with the Securities and Exchange Commission (“SEC”) on March 8, 2019, which is available on the SEC’s website at www.sec.gov. Basis of Presentation The unaudited condensed consolidated financial statements of the Company are presented for APX Group Holdings, Inc. (“Holdings") and its wholly-owned subsidiaries. The Company has prepared the accompanying unaudited condensed consolidated financial statements pursuant to GAAP. Preparing financial statements requires the Company to make estimates and assumptions that affect the amounts that are reported in the condensed 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 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, the option to 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 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 and estimated write-offs 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 up to $4,000 . The annual percentage rates on these loans range between 0% and 9.99% , and are either installment or revolving loans with a 42 or 60 month term. Loan terms are determined based on the customer's credit quality. 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 Condensed Consolidated Statement of Operations. (See Note 8 ). 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 condensed consolidated balance sheets for the present value of the receivables that are expected to be collected beyond 12 months of the reporting date. The unbilled receivable amounts that are expected to be collected within 12 months of the reporting date are included as a short-term notes receivable within accounts and notes receivable, net on the condensed consolidated balance sheets. The billed amounts of notes receivables are included in accounts receivable within accounts and notes receivable, net on the condensed consolidated balance sheets. The Company imputes the interest on the RIC receivable using a risk adjusted market interest rate and records it as an adjustment to deferred revenue and as an adjustment to the face amount of the related receivable. The 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 condensed 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. Accounts Receivable Accounts receivable consists primarily of amounts due from subscribers for recurring monthly monitoring Services and the billed portion of RIC receivables. The accounts receivable are recorded at invoiced amounts and are non-interest bearing and are included within accounts and notes receivable, net on the condensed consolidated balance sheets. Accounts receivable totaled $22.1 million and $16.5 million at September 30, 2019 and December 31, 2018 , respectively net of the allowance for doubtful accounts of $6.7 million and $5.6 million at September 30, 2019 and December 31, 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 unaudited condensed consolidated statements of operations and totaled $5.4 million and $5.9 million for the three months ended September 30, 2019 and 2018 , respectively, and $17.0 million and $14.3 million for the nine months ended September 30, 2019 and 2018 , respectively. The changes in the Company’s allowance for accounts receivable were as follows (in thousands): Nine Months Ended September 30, 2019 Twelve Months Ended December 31, 2018 Beginning balance $ 5,594 $ 5,356 Provision for doubtful accounts 16,988 19,405 Write-offs and adjustments (15,843 ) (19,167 ) Balance at end of period $ 6,739 $ 5,594 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 of 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 . 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. These costs are deferred and amortized on a straight-line basis over the expected period of benefit that the Company has determined to be five years . 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. These deferred costs are periodically reviewed for impairment. 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 condensed 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 Products and parts, are stated at the lower of cost or net realizable value with cost determined under the first-in, first-out (“FIFO”) method. The Company adjusts the inventory balance based on anticipated obsolescence, usage and historical write-offs. 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 three and nine months ended September 30, 2019 and 2018 , 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): Three Months Ended September 30, Nine Months Ended September 30, 2019 2018 2019 2018 Amortization of capitalized contract costs $ 111,177 $ 101,498 $ 323,450 $ 294,802 Amortization of definite-lived intangibles 20,016 22,741 60,484 68,193 Depreciation of property, plant and equipment 6,343 6,397 19,327 18,772 Total depreciation and amortization $ 137,536 $ 130,636 $ 403,261 $ 381,767 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 condensed consolidated balance sheets. Finance lease assets are included in property, plant and equipment, net on the condensed 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 condensed consolidated balance sheets and capital lease assets were included in property, plant and equipment, net on the condensed 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 condensed consolidated financial statements. See Recently Adopted Accounting Standards below and note 12 "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 , including $0.7 million of equity investments without readily determinable fair values. The Company did not hold any equity security investments as of September 30, 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 Group, Inc.’s (“APX”) revolving credit facility are amortized over the amended maturity dates discussed in Note 3 . Deferred financing costs included in the accompanying unaudited condensed consolidated balance sheets within deferred financing costs, net at September 30, 2019 and December 31, 2018 were $1.3 million and $2.1 million , net of accumulated amortization of $10.3 million and $9.6 million , respectively. Deferred financing costs included in the accompanying unaudited condensed consolidated balance sheets within notes payable, net at September 30, 2019 and December 31, 2018 were $29.3 million and $32.4 million , net of accumulated amortization of $61.3 million and $54.6 million , respectively. Amortization expense on deferred financing costs recognized and included in interest expense in the accompanying unaudited condensed consolidated statements of operations, totaled $2.4 million and $2.6 million for the three months ended September 30, 2019 and 2018 , respectively, and $7.4 million and $7.9 million for the nine months ended September 30, 2019 and 2018 , respectively (See Note 3 ). 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 $5.2 million and $4.9 million at September 30, 2019 and December 31, 2018 , respectively, and the amount included in other long-term obligations was $27.7 million and $17.6 million at September 30, 2019 and December 31, 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 10 ). Advertising Expense Advertising costs are expensed as incurred. Advertising costs were $16.1 million and $13.1 million for the three months ended September 30, 2019 and 2018 , respectively, and $46.1 million and $34.8 million for the nine months ended September 30, 2019 and 2018 , 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. Concentrations of Credit Risk Financial instruments that potentially subject the Company to concentration of credit risk consist principally of receivables and cash. At times during the year, the Company maintains cash balances in excess of insured limits. The Company is not dependent on any single customer or geographic location. The loss of a customer would not adversely impact the Company’s operating results or financial position. Concentrations of Supply Risk As of September 30, 2019 , approximately 87% of the Company’s installed panels were SkyControl panels, 13% were 2GIG Go!Control panels and 1% were other 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 nine months ended September 30, 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 v

Revenue and Capitalized Contrac

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 nine months ended September 30, 2019 and 2018 , the Company recognized revenues of $178.4 million and $132.4 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 September 30, 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 60% of the revenue related to these remaining performance obligations over the next 24 months, with the remaining balance recognized over an additional 36 months. Timing of Revenue Recognition The Company considers Products, related installation, and its proprietary back-end cloud platform software and services an integrated system that allows the Company’s customers to monitor, control and protect their homes. These Smart Home Services are accounted for as a single performance obligation that is recognized over the customer’s contract term, which is generally three to five years . Capitalized Contract Costs Capitalized contract costs generally include commissions, other compensation and related costs paid directly for the generation and installation of new or modified customer contracts, as well as the cost of Products installed in the customer home at the commencement or modification of the contract. 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 .

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 September 30, 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 September 30, 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 8.50% 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. The 2024 notes are secured, on a pari passu basis, by the collateral securing obligations under the 2022 private placement notes, the 2022 notes, the revolving credit facilities and the Term Loan, in all cases, subject to certain exceptions and permitted liens. Interest accrues at the rate of 8.75% per annum for the 2020 notes, 8.875% per annum for the 2022 private placement notes, 7.875% per annum for the 2022 notes, 7.625% per annum for the 2023 notes and 8.50% per annum for the 2024 notes. Interest on the 2020 notes, 2022 private placement notes and 2022 notes is payable semiannually in arrears on June 1 and December 1 of each year. Interest on the 2023 notes is payable semiannually in arrears on March 1 and September 1 of each year. Interest on the 2024 notes is payable semiannually in arrears on May 1 and November 1 each year. APX may redeem the Notes at the prices and on the terms specified in the applicable indenture, or the note purchase agreement. Term Loan In September 2018, APX entered into a credit agreement (the “September 2018 issuance”) for total term loans of $810.0 million (the “Term Loan”). The Company is required to make quarterly amortization payments under the Term Loan in an amount equal to 0.25% of the aggregate principal amount of Term Loan outstanding on the closing date thereof. The remaining principal amount outstanding under the Term Loan will be due and payable in full on March 31, 2024, unless, under “Springing Maturity” provision, (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 Term Loan 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 Term Loan will mature on June 1, 2023. The net proceeds from the Term Loan were used in-part to redeem in full the entire $269.5 million outstanding aggregate principal amount of the 2019 notes and pay the related accrued interest and redemption premium, to repurchase approximately $250.7 million aggregate principal amount of the outstanding 2020 notes, to repay the outstanding borrowings under the revolving credit facility and to pay fees and expenses related to the Term Loan and the transactions described above. Borrowings under the Term Loan bear interest at a rate per annum equal to an applicable margin plus, at the Company'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 is 4.0% per annum and the applicable margin for LIBOR rate-based borrowings is 5.0% per annum. APX may prepay the Term Loan at the prices and on the terms specified in the credit agreement covering the Term Loan. Debt Modifications and Extinguishments The Company performs analyses on a creditor-by-creditor basis for debt modifications and extinguishments to determine if repurchased debt was substantially different than debt issued to determine the appropriate accounting treatment of associated issuance costs. As a result of these analyses, the following amounts of other expense and loss on extinguishment and deferred financing costs were recorded (in thousands): Original premium extinguished Previously deferred financing costs extinguished New financing costs Total other expense and loss on extinguishment New deferred financing costs Nine months ended September 30, 2019 May 2019 issuance $ (588 ) $ 1,395 $ — $ 807 $ 4,956 Three and nine months ended September 30, 2018 September 2018 issuance $ (953 ) $ 4,207 $ 11,317 $ 14,571 $ 10,275 Deferred financing costs are amortized to interest expense over the life of the issued debt. The Company had no debt issuances or related modification or extinguishment costs during the three months ended September 30, 2019. The following table presents deferred financing activity for the nine months ended September 30, 2019 and year ended December 31, 2018 (in thousands): Unamortized Deferred Financing Costs Balance December 31, 2018 Additions Early Extinguishment Amortized Balance September 30, 2019 Revolving Credit Facility $ 2,058 $ — $ — $ (710 ) $ 1,348 2020 Notes 5,380 — (1,395 ) (1,795 ) 2,190 2022 Private Placement Notes 602 — — (113 ) 489 2022 Notes 12,799 — — (2,451 ) 10,348 2023 Notes 3,922 — — (630 ) 3,292 2024 Notes — 4,956 — (300 ) 4,656 Term Loan 9,662 — (1,380 ) 8,282 Total Deferred Financing Costs $ 34,423 $ 4,956 $ (1,395 ) $ (7,379 ) $ 30,605 Unamortized Deferred Financing Costs Balance December 31, 2017 Additions Early Extinguishment Amortized Balance December 31, 2018 Revolving Credit Facility $ 3,099 $ — $ — $ (1,041 ) $ 2,058 2019 Notes 2,877 — (1,877 ) (1,000 ) — 2020 Notes 11,209 — (2,330 ) (3,499 ) 5,380 2022 Private Placement Notes 752 — — (150 ) 602 2022 Notes 16,067 — — (3,268 ) 12,799 2023 Notes 4,762 — — (840 ) 3,922 Term Loan — 10,275 — (613 ) 9,662 Total Deferred Financing Costs $ 38,766 $ 10,275 $ (4,207 ) $ (10,411 ) $ 34,423 Revolving Credit Facility On November 16, 2012, APX entered into a $200.0 million senior secured revolving credit facility, with a five year maturity. On March 6, 2015, APX amended and restated the credit agreement governing the revolving credit facility to provide for, among other things, (1) an increase in the aggregate commitments previously available to APX thereunder from $200.0 million to $289.4 million (“Revolving Commitments”) and (2) the extension of the maturity date with respect to certain of the previously available commitments. On August 10, 2017, APX further amended and restated the credit agreement governing the revolving credit facility to provide for, among other things, (1) an increase in the aggregate commitments previously available to 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 and, when in effect, the Series D Revolving Commitments of approximately $15.4 million was 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, and, when in effect, the Series D Revolving Commitments is currently 3.0% per annum and (b) under the Series B Revolving Commitments is currently 4.0% . The applicable margin for borrowings under the revolving credit facility is subject to one step-down of 25 basis points based on APX meeting a consolidated first lien net leverage ratio test at the end of each fiscal quarter. Outstanding borrowings under the amended and restated revolving credit facility are allocated on a pro-rata basis between each Series based on the total Revolving Commitments. In addition to paying interest on outstanding principal under the revolving credit facility, APX is required to pay a quarterly commitment fee (which will be subject to one interest rate step-down of 12.5 basis points, based on APX meeting a consolidated first lien net leverage ratio test) to the lenders under the revolving credit facility in respect of the unutilized commitments thereunder.

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 condensed consolidated unaudited balance sheets. The following table summarizes the RIC receivables (in thousands): September 30, 2019 December 31, 2018 RIC receivables, gross $ 200,123 $ 175,250 RIC Discount (64,263 ) (34,163 ) RIC receivables, net $ 135,860 $ 141,087 Classified on the condensed consolidated unaudited balance sheets as: Accounts and notes receivable, net $ 42,516 $ 32,185 Long-term notes receivables and other assets, net 93,344 108,902 RIC receivables, net $ 135,860 $ 141,087 The changes in the Company’s RIC Discount were as follows (in thousands): Nine months ended September 30, 2019 Twelve months ended December 31, 2018 RIC Discount, beginning of period $ 34,163 $ 36,048 Write-offs, net of recoveries (16,445 ) (26,360 ) Change in RIC Discount on short-term and long-term RIC receivables 46,545 24,475 RIC Discount, end of period $ 64,263 $ 34,163 The amount of RIC imputed interest income recognized in recurring and other revenue was $4.0 million and $4.1 million during the three months ended September 30, 2019 and 2018 , respectively, and $10.6 million and $10.9 million during the nine months ended September 30, 2019 and 2018 , 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 three and nine months ended September 30, 2019.

The lease term was for seven years, with an option to become the licensor of record with the Federal Communications Commission (“FCC”) with respect to the applicable spectrum licenses at the end of this term for a nominal fee. The Company acquired $31.3 million of spectrum licenses, measured using the present value of the lease payments, and recorded an intangible asset and a corresponding liability within other long-term obligations. While licenses are issued for only a fixed time, such licenses are subject to renewal by the FCC. In January 2018, Vivint Wireless and Verizon consummated the transactions contemplated by a termination agreement to which the parties agreed, among other things, to terminate the spectrum leases between Vivint Wireless and Nextlink, a subsidiary of Verizon, in exchange for a cash payment by Verizon to Vivint Wireless. The calculation of the gain recorded included cash proceeds of $55.0 million , extinguishment of the spectrum license liability of $27.9 million , offset by the write-off of the spectrum license asset in the amount of $31.3 million and regulatory costs associated with the sale of $1.2 million for a total net gain on sale of $50.4 million which is included in other income, net in the condensed consolidated statement of operations. In May 2019, the Company acquired majority ownership interest in CrowdStorage, Inc. (“CrowdStorage”), a distributed cloud storage solution company. The Company determined that CrowdStorage was a variable interest entity and the Company was the primary beneficiary, because CrowdStorage was dependent on the Company for ongoing financial support. As part of this acquisition, the Company recognized a definite-lived intangible asset of $1.8 million , included within the other technology asset class in the above table.

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 September 30, 2019 and December 31, 2018 (in thousands): September 30, 2019 December 31, 2018 Consumer Financing Program Contractual Obligations: Fair value $ 143,447 $ 117,620 Notional amount 532,150 368,708 Classified on the condensed consolidated unaudited balance sheets as: Accrued expenses and other current liabilities 82,047 67,710 Other long-term obligations 61,400 49,910 Total Consumer Financing Program Contractual Obligation $ 143,447 $ 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 liability instrument for the nine months ended September 30, 2019 and the twelve months ended December 31, 2018 (in thousands): Nine months ended September 30, 2019 Twelve months ended December 31, 2018 Balance, beginning of period $ 117,620 $ 46,496 Additions 71,433 93,095 Settlements (40,470 ) (34,587 ) Net (gains) losses included in earnings (5,136 ) 12,616 Balance, end of period $ 143,447 $ 117,620

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes In order to determine the quarterly provision for income taxes, the Company uses an estimated annual effective tax rate, which is based on expected annual income and statutory tax rates in the various jurisdictions in which the Company operates. Certain significant or unusual items are separately recognized in the quarter during which they occur and can be a source of variability in the effective tax rates from quarter to quarter. The Company’s effective income tax benefit rate for the nine months ended September 30, 2019 and 2018 was approximately 0.20% and 0.45% , respectively. Income tax expense for the nine months ended September 30, 2019 was affected by year to date projected loss in Canada and estimated minimum state taxes in the US. Both the 2019 and 2018 effective tax rates differ from the statutory rate primarily due to the combination of not benefiting from expected pre-tax US losses, a result of changes to the valuation allowance, and recognizing current state income tax expense for minimum state taxes. Significant judgment is required in determining the Company’s provision for income taxes, recording valuation allowances against deferred tax assets, and evaluating the Company’s uncertain tax positions. In evaluating the ability to realize its deferred tax assets, in full or in part, the Company considers all available positive and negative evidence, including past operating results, forecasted future earnings, and prudent and feasible tax planning strategies. Due to historical net losses incurred and the uncertainty of realizing the deferred tax assets, for all the periods presented, the Company has maintained a domestic valuation allowance against the deferred tax assets that remain after offset by domestic deferred tax liabilities, and the company currently anticipates recording a valuation allowance against net foreign deferred tax assets by the end of the current year.

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 Blackstone, has authorized the award of profits interests, representing the right to share a portion of the value appreciation on the initial capital contributions to 313 (“Incentive Units”). As of September 30, 2019 , 84,866,126 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 outstanding 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 rates between 0.62% and 2.61% . Vivint Stock Appreciation Rights The Company’s subsidiary, Vivint Group, Inc. (“Vivint Group”), has awarded Stock Appreciation Rights (“SARs”) to various levels of key employees 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, 45,176,970 SARs were outstanding as of September 30, 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 6.47 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. 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. 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 September 30, 2019 , there was $0.3 million of unrecognized compensation expense related to outstanding RSUs, which will be recognized over a period of 1.9 years . Stock-based compensation expense in connection with all stock-based awards is presented as follows (in thousands): Three Months Ended September 30, Nine Months Ended September 30, 2019 2018 2019 2018 Operating expenses $ 139 $ 102 $ 234 $ 147 Selling expenses 209 235 378 361 General and administrative expenses 1,110 770 2,680 1,143 Total stock-based compensation $ 1,458 $ 1,107 $ 3,292 $ 1,651

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 September 30, 2019 and December 31, 2018 , respectively. In conjunction with one of the settlements, the Company is obligated to pay certain future royalties, based on sales of future Products. Operating Leases The Company leases office and warehouse space 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 three and nine months ended September 30, 2018 was $4.8 million and $13.6 million , respectively. Capital Leases The Company also enters into certain capital leases with expiration dates through July 2023 . On an ongoing basis, the Company enters into vehicle lease agreements under a Fleet Lease Agreement. The lease agreements are typically 36 month leases for each vehicle. As of December 31, 2018 , the capital lease obligation balance was $13.3 million . See Note 12 "Leases" for additional information related to the impact of adopting Topic 842.

In August 2017, the Company entered into a sales dealer agreement with Solar, pursuant to which each company will act as a non-exclusive dealer for the other party to market, promote and sell each other’s products. The agreement has an initial term of two years and replaces substantially all of the activities being undertaken under the parties’ former marketing and customer relations agreement.

In connection with the Merger, 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 $2.2 million and $1.1 million during the three months ended September 30, 2019 and 2018 , respectively, and $4.2 million and $3.2 million during the nine months ended September 30, 2019 and 2018 , respectively.

Since January 2018, participants in the 401(k) plans have been eligible for the Company's matching program. Under this matching program, the Company matches an employee’s contributions to the 401(k) savings plan dollar-for-dollar up to 1% of such employee’s eligible earnings and $0.50 for every $1.00 for the next 5% of such employee’s eligible earnings.

Restructuring and Related Activities [Abstract]
Restructuring and Asset Impairment Charges	Restructuring and Asset Impairment Charges In July 2018, the Company announced a number of cost reduction initiatives that are expected to reduce certain of the Company’s General and Administrative, Customer Service, and Sales Support fixed costs. 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, 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 $0.5 million and $4.7 million during the three and nine months ended September 30, 2018, respectively. The following table presents accrued restructuring for employee severance and termination benefits activity for the nine months ended September 30, 2019 and the twelve months ended December 31, 2018 (in thousands): Employee severance and termination benefits Accrued restructuring balance as of December 31, 2017 $ — Restructuring expenses 4,683 Cash payments (4,341 ) Accrued restructuring balance as of December 31, 2018 342 Cash payments (342 ) Accrued restructuring balance as of September 30, 2019 $ — Wireless Spin-Off As described above, on July 31, 2019, the Company completed a spin-off of Wireless.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The unaudited condensed consolidated financial statements of the Company are presented for APX Group Holdings, Inc. (“Holdings") and its wholly-owned subsidiaries. The Company has prepared the accompanying unaudited condensed consolidated financial statements pursuant to GAAP. Preparing financial statements requires the Company to make estimates and assumptions that affect the amounts that are reported in the condensed consolidated financial statements and accompanying disclosures. Although these estimates are based on the Company’s best knowledge of current events and actions that the Company may undertake in the future, actual results may be different from the Company’s estimates. The results of operations presented herein are not necessarily indicative of the Company’s results for any future period.
Vivint Flex Pay	Vivint Flex Pay 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 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, the option to 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 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 and estimated write-offs 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 up to $4,000 . The annual percentage rates on these loans range between 0% and 9.99% , and are either installment or revolving loans with a 42 or 60 month term. Loan terms are determined based on the customer's credit quality. 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 Condensed Consolidated Statement of Operations. (See Note 8 ). 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	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 condensed consolidated balance sheets for the present value of the receivables that are expected to be collected beyond 12 months of the reporting date. The unbilled receivable amounts that are expected to be collected within 12 months of the reporting date are included as a short-term notes receivable within accounts and notes receivable, net on the condensed consolidated balance sheets. The billed amounts of notes receivables are included in accounts receivable within accounts and notes receivable, net on the condensed consolidated balance sheets. The Company imputes the interest on the RIC receivable using a risk adjusted market interest rate and records it as an adjustment to deferred revenue and as an adjustment to the face amount of the related receivable. The 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 condensed 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.
Accounts Receivable	Accounts Receivable Accounts receivable consists primarily of amounts due from subscribers for recurring monthly monitoring Services and the billed portion of RIC receivables. The accounts receivable are recorded at invoiced amounts and are non-interest bearing and are included within accounts and notes receivable, net on the condensed consolidated balance sheets. Accounts receivable totaled $22.1 million and $16.5 million at September 30, 2019 and December 31, 2018 , respectively net of the allowance for doubtful accounts of $6.7 million and $5.6 million at September 30, 2019 and December 31, 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 unaudited condensed consolidated statements of operations and totaled $5.4 million and $5.9 million for the three months ended September 30, 2019 and 2018 , respectively, and $17.0 million and $14.3 million for the nine months ended September 30, 2019 and 2018 , respectively.
Revenue Recognition	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 of 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 . 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. These costs are deferred and amortized on a straight-line basis over the expected period of benefit that the Company has determined to be five years . 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. These deferred costs are periodically reviewed for impairment. 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 condensed 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 Products and parts, are stated at the lower of cost or net realizable value with cost determined under the first-in, first-out (“FIFO”) method. The Company adjusts the inventory balance based on anticipated obsolescence, usage and historical write-offs.
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.
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 condensed consolidated balance sheets. Finance lease assets are included in property, plant and equipment, net on the condensed 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.
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 , including $0.7 million of equity investments without readily determinable fair values. The Company did not hold any equity security investments as of September 30, 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 Group, Inc.’s (“APX”) revolving credit facility are amortized over the amended maturity dates discussed in Note 3 .
Residual Income Plans	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.
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 10 ).
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.
Concentrations of Credit Risk	Concentrations of Credit Risk Financial instruments that potentially subject the Company to concentration of credit risk consist principally of receivables and cash. At times during the year, the Company maintains cash balances in excess of insured limits. The Company is not dependent on any single customer or geographic location. The loss of a customer would not adversely impact the Company’s operating results or financial position.
Concentrations of Supply Risk	Concentrations of Supply Risk As of September 30, 2019 , approximately 87% of the Company’s installed panels were SkyControl panels, 13% were 2GIG Go!Control panels and 1% were other 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 nine months ended September 30, 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 September 30, 2019 consisted of one reporting unit. As of September 30, 2019 , there were no changes in facts and circumstances since the most recent annual impairment analysis to indicate impairment existed.
Foreign Currency Translation and Other Comprehensive Income	Foreign Currency Translation and Other Comprehensive Income The functional 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 income (loss) 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 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 condensed consolidated statement of operations. The Company has determined that settlement of Vivint Canada, Inc. intercompany balances is anticipated and therefore such balances are deemed to be of a short term nature.
Letters of Credit	Letters of Credit As of each September 30, 2019 and December 31, 2018 , the Company had $13.8 million of letters of credit issued in the ordinary course of business, all of which are undrawn.
Restructuring and Asset Impairment Charges	Restructuring and Asset Impairment Charges Restructuring and asset impairment charges represent expenses incurred in relation to activities to exit or disposal 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 15 ).
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 is evaluating the adoption of ASU 2016-13 and plans to provide additional information about its expected impact at a future date. Recently Adopted Accounting Standards 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 condensed consolidated statements of operations or its condensed 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 12 "Leases" for additional information related to the impact of adopting this standard.
