Accounting Policies [Abstract]
Basis of Presentation and Significant Accounting Policies	NOTE 1—BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES Unaudited Interim Financial Statements These unaudited condensed consolidated financial statements and notes should be read in conjunction with the Company’s audited consolidated financial statements and related notes as set forth in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2015, as filed with the Securities and Exchange Commission (“SEC”) on March 10, 2016, which is available on the SEC’s website at www.sec.gov. Basis of Presentation During the three months ended March 31, 2015, the Company recorded certain out-of-period adjustments totaling $2.0 million, primarily associated with the timing of the recognition of deferred revenue related to 2014 recurring monitoring services. As a result of these adjustments, recurring revenues increased for the three months ended March 31, 2015 and deferred revenue decreased by $2.0 million, respectively. The Company evaluated the impact of the out-of-period adjustments and determined that they are immaterial to the unaudited condensed consolidated financial statements for the three months ended March 31, 2015. Restructuring and Asset Impairment Charges Use of Estimates Changes in Presentation of Comparative Financial Statements Revenue Recognition— Recurring revenue for the Company’s subscriber contracts is billed in advance, generally monthly, pursuant to the terms of subscriber contracts and recognized ratably over the service period. Costs of providing ongoing recurring services are expensed in the period incurred. Service and other sales revenue is recognized as services are provided or when title to the products and equipment sold transfers to the customer. Contract fulfillment revenue, included in service and other sales, is recognized when payment is received from customers who cancel their contract in-term. Revenue from sales of products that are not part of the basic equipment package is generally recognized upon delivery of products. Activation fees represent upfront one-time charges billed to subscribers at the time of installation and are deferred. These fees are recognized over the estimated customer life of 12 years using a 150% declining balance method, which converts to a straight-line methodology after approximately five years to approximate the anticipated life of the customer. Subscriber Acquisition Costs On the condensed consolidated statement of cash flows, subscriber acquisition costs that are comprised of equipment and related installation costs purchased for or used in subscriber contracts in which the Company retains ownership to the equipment are classified as investing activities and reported as “Subscriber acquisition costs—company owned equipment”. All other subscriber acquisition costs are classified as operating activities and reported as “Subscriber acquisition costs—deferred contract costs” on the condensed consolidated statements of cash flows as these assets represent deferred costs associated with customer contracts. Cash and Cash Equivalents— Restricted Cash and Cash Equivalents Accounts Receivable The changes in the Company’s allowance for accounts receivable were as follows for the periods ended (in thousands): Three Months Ended March 31, 2016 2015 Beginning balance $ 3,541 $ 3,373 Provision for doubtful accounts 3,980 3,557 Write-offs and adjustments (4,499 ) (4,022 ) Balance at end of period $ 3,022 $ 2,908 Inventories Long-lived Assets and Intangibles During the fiscal quarter ended March 31, 2016, the Company adopted guidance issued by the Financial Accounting Standards Board (“FASB”) which provides new standards to determine whether a cloud computing arrangement includes a software license. The guidance requires the company to determine if an internal use software obtained in a cloud hosting arrangement contains a contractual right to take possession of the software and if it is feasible to either run the software on internal hardware or contract with an unrelated vendor to host the software. If both criteria are met, the company will consider the arrangement to include a software license and classify the purchase as an intangible. The company has elected to adopt the guidance prospectively to all arrangements entered into or materially modified after the beginning of 2016. The company did not enter into, or modify, any material arrangements during the fiscal quarter ended March 31, 2016. Long-term Investments Deferred Financing Costs During the fiscal quarter ended March 31, 2016, the Company adopted guidance issued by the FASB requiring debt issuance costs related to a recognized debt liability to be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The Company has applied this retrospectively resulting in a reduction to deferred financing costs, net by $40.2 million as of December 31, 2015 with a corresponding decrease to notes payable, net. Residual Income Plan Stock-Based Compensation Advertising Expense Income Taxes The Company recognizes the effect of an uncertain income tax position on the income tax return at the largest amount that is more-likely-than-not to be sustained upon audit by the relevant taxing authority. An uncertain income tax position will not be recognized if it has less than a 50% likelihood of being sustained. The Company’s policy for recording interest and penalties is to record such items as a component of the provision for income taxes. Concentrations of Credit Risk Concentrations of Supply Risk Fair Value Measurement 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 three months ended March 31, 2016 and 2015. 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 Foreign Currency Translation and Other Comprehensive Income When intercompany foreign currency transactions between entities included in the consolidated financial statements are of a long term investment nature (i.e., those for which settlement is not planned or anticipated in the foreseeable future) foreign currency translation adjustments resulting from those transactions are included in stockholders’ deficit as accumulated other comprehensive loss. When intercompany transactions are deemed to be of a short term nature, translation adjustments are required to be included in the condensed consolidated statement of operations. Translation gains related to intercompany balances were $4.7 million and $0 for the three months ended March 31, 2016 and 2015, respectively. Letters of Credit New Accounting Pronouncements In March 2016, the FASB issued ASU 2016-08 to clarify the implementation guidance on principal versus agent considerations as it relates to Revenue from Contracts with Customers (Topic 606). This update is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017 and must be applied retrospectively, with early adoption permitted. The Company is evaluating the new guidance and plans to provide additional information about its expected impact at a future date. In March 2016, the FASB issued ASU 2016-07 which eliminates the requirement to retroactively adopt the equity method of accounting when an investment qualifies for use of the equity method as a result of an increase in the level of ownership interest or degree of influence. This update is effective for fiscal years, and interim periods within those years, beginning after December 15, 2016 and must be applied prospectively, with early adoption permitted. The Company plans to adopt this update on the effective date and the adoption is not expected to materially impact the consolidated financial statements. In March 2016, the FASB issued ASU 2016-06 to clarify the assessment of contingent put and call options in debt instruments as it relates to Derivatives and Hedging (Topic 815). The amendments in this update clarify the requirements for assessing whether contingent call (put) options that can accelerate the payment of principal on debt instruments are clearly and closely related to their debt hosts. An entity performing the assessment under the amendments in this update is required to assess the embedded call (put) options solely in accordance with the four-step decision sequence. This update is effective for fiscal years, and interim periods within those years, beginning after December 15, 2016 and must be applied using a modified retrospective approach, with early adoption permitted. The Company plans to adopt this update on the effective date and is not expected to materially impact the consolidated financial statements. In February 2016, the FASB issued ASU 2016-02 to increase transparency and comparability among organizations as it relates to lease assets and lease liabilities. The update requires that lease assets and lease liabilities be recognized on the balance sheet, and that key information about leasing arrangements be disclosed. Prior to this update, GAAP did not require operating leases to be recognized as lease assets and lease liabilities on the balance sheet. This update is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018 and must be applied using a modified retrospective approach, with early adoption permitted. The Company is evaluating the new guidance and plans to provide additional information about its expected impact at a future date. In January 2016, the FASB issued ASU 2016-01 to address certain aspects of the recognition, measurement, presentation, and disclosure of financial instruments. The main provisions of this update require equity investments to be measured at fair value with changes in fair value recognized in earnings, allows a company to value equity investments without a readily determined fair value at cost, less any impairments, and simplifies the assessment of impairments of equity investments without a readily determinable fair value by requiring a qualitative assessment. This update is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017. An entity should apply the amendments by means of a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption. The amendments related to equity securities without readily determinable fair values (including disclosure requirements) should be applied prospectively to equity investments that exist as of the date of adoption of the Update. Early adoption is permitted. The Company is evaluating the new guidance and plans to provide additional information about its expected impact at a future date. In July 2015, the FASB issued ASU 2015-11 to simplify the measurement of inventory. Prior to this update, GAAP required the measurement of inventory at the lower of cost or market, where market could be replacement cost, net realizable value, or net realizable value less an approximately normal profit margin. This update requires that an entity measure inventory at the lower of cost or net realizable value, where net realizable value is the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. This guidance is effective for fiscal years beginning after December 15, 2016, and for interim periods within those fiscal years and should be applied prospectively, with early adoption permitted. The Company plans to adopt this update on the effective date and the adoption is not expected to impact the consolidated financial statements. In May 2014, the FASB issued ASU 2014-09 which clarifies the principles used to recognize revenue for all entities. The new guidance requires companies to recognize revenue when it transfers goods or services to a customer in an amount that reflects the consideration to which a company expects to be entitled. Pursuant to ASU 2015-14, the guidance is effective for annual and interim periods beginning after December 15, 2017. The guidance allows for either a “full retrospective” adoption or a “modified retrospective” adoption, with early adoption permitted. The Company is evaluating the new guidance and plans to provide additional information about its expected impact at a future date.

Preparing financial statements requires the Company to make estimates and assumptions that affect the amounts that are reported in the consolidated financial statements and accompanying disclosures. Although these estimates are based on the Company’s best knowledge of current events and actions that the Company may undertake in the future, actual results may be different from the Company’s estimates. The results of operations presented herein are not necessarily indicative of the Company’s results for any future period. During the year ended December 31, 2015, the Company recorded certain out-of-period adjustments totaling $2.0 million, primarily associated with the timing of the recognition of deferred revenue related to 2014 recurring monitoring services. As a result of these adjustments, recurring revenues increased for the year ended December 31, 2015 and deferred revenue decreased by $2.0 million, respectively. The Company evaluated the impact of the out-of-period adjustments and determined that they are immaterial to the consolidated financial statements for the year ended December 31, 2015. Restructuring and Asset Impairment Charges Use of Estimates Principles of Consolidation Changes in Presentation of Comparative Financial Statements Revenue Recognition Recurring revenue for the Company’s subscriber contracts are billed in advance, generally monthly, pursuant to the terms of subscriber contracts and recognized ratably over the service period. Costs of providing ongoing recurring services are expensed in the period incurred. Service and other sales revenue is recognized as services are provided or when title to the products and equipment sold transfers to the customer. Contract fulfillment revenue, included in service and other sales, is recognized when payment is received from customers who cancel their contract in-term. Revenue from sales of products that are not part of the basic equipment package is recognized upon delivery of products. Activation fees represent upfront one-time charges billed to subscribers at the time of installation and are deferred. These fees are recognized over the estimated customer life of 12 years using a 150% declining balance method, which converts to a straight-line methodology after approximately five years to approximate the anticipated life of the customer. Through the date of the 2GIG Sale, service and other sales revenue included net recurring services revenue, which was based on back-end services provided by Alarm.com for all panels sold to distributors and direct-sell dealers and subsequently placed in service at end-user locations. The Company received a fixed monthly amount from Alarm.com for each system installed with non-Vivint customers that used the Alarm.com platform. Subscriber Acquisition Costs On the consolidated statement of cash flows, subscriber acquisition costs that are comprised of equipment and related installation costs purchased for or used in subscriber contracts in which the Company retains ownership to the equipment are classified as investing activities and reported as “Subscriber acquisition costs—company owned equipment.” All other subscriber acquisition costs are classified as operating activities and reported as “Subscriber acquisition costs—deferred contract costs” on the consolidated statements of cash flows as these assets represent deferred costs associated with the creation of customer contracts. Cash and Cash Equivalents Restricted Cash and Cash Equivalents Accounts Receivable The changes in the Company’s allowance for accounts receivable were as follows for the periods ended (in thousands): Year ended December 31, 2015 2014 2013 Beginning balance $ 3,373 $ 1,901 $ 2,301 Provision for doubtful accounts 14,924 15,656 10,360 Write-offs and adjustments (14,756 ) (14,184 ) (10,760 ) Balance at end of period $ 3,541 $ 3,373 $ 1,901 Inventories Long-lived Assets and Intangibles Long-term Investments Deferred Financing Costs Residual Income Plan Stock-Based Compensation Advertising Expense Income Taxes 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. Contracts Sold Concentrations of Credit Risk Concentrations of Supply Risk Fair Value Measurement Level 1: Quoted prices in active markets that are accessible at the measurement date for assets and liabilities. Level 2: Observable prices that are based on inputs not quoted in active markets, but corroborated by market data. Level 3: Unobservable inputs are used when little or no market data is available. This hierarchy requires the Company to minimize the use of unobservable inputs and to use observable market data, if available, when determining fair value. The Company recognizes transfers between levels of the hierarchy based on the fair values of the respective financial measurements at the end of the reporting period in which the transfer occurred. There were no transfers between levels of the fair value hierarchy during the years ended December 31, 2015 and 2014. 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 Foreign Currency Translation and Other Comprehensive Income When intercompany foreign currency transactions between entities included in the consolidated financial statements are of a long term investment nature (i.e., those for which settlement is not planned or anticipated in the foreseeable future) foreign currency translation adjustments resulting from those transactions are included in stockholders’ (deficit) equity as accumulated other comprehensive loss. When intercompany transactions are deemed to be of a short term nature, translation adjustments are required to be included in the consolidated statement of operations. Beginning in July 2015, we determined that settlement of these intercompany balances was anticipated and therefore these balances are not considered to be long-term investments and any subsequent translation gains or losses are recorded in income. Translation losses related to intercompany balances were $9.4 million, $0 and $0 for the years ended December 31, 2015, 2014, and 2013, respectively. Letters of Credit New Accounting Pronouncements In July 2015, the Financial Accounting Standards Board issued authoritative guidance to simplify the measurement of inventory. Prior to this update, generally accepted accounting principles required the measurement of inventory at the lower of cost or market, where market could be replacement cost, net realizable value, or net realizable value less an approximately normal profit margin. This update requires that an entity measure inventory at the lower of cost or net realizable value, where net realizable value is the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. This guidance is effective for fiscal years beginning after December 15, 2016, and for interim periods within fiscal years beginning after December 15, 2017 and should be applied prospectively, with early adoption permitted. The Company plans to adopt this update on the effective date and is not expected to materially impact the consolidated financial statements. In May 2015, the Financial Accounting Standards Board issued authoritative guidance related to customer’s accounting for fees paid in a cloud computing arrangement and is issued in an attempt to simplify existing generally accepted accounting principles. The update provides guidance to help entities determine whether a cloud computing arrangement includes a software license. This guidance is effective for fiscal years beginning after December 15, 2015, and for interim periods within fiscal years beginning after December 15, 2016 with early adoption permitted. The Company plans to adopt this update on the effective date and is not expected to materially impact the consolidated financial statements. In April 2015, the Financial Accounting Standards Board issued authoritative guidance (“ASU 2015-03”) to simplify the presentation of debt issuance costs. This update requires debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The guidance is effective for fiscal years beginning after December 15, 2015, and for interim periods within fiscal years beginning after December 15, 2016. Effective January 1, 2016, the Company adopted this standard resulting in a retrospective reduction to deferred financing costs, net by $40.2 million and $48.1 million as of December 31, 2015 and December 31, 2014, respectively, with a corresponding decrease to notes payable, net. This update does not impact the consolidated statements of operations, consolidated statements of comprehensive loss or consolidated statements of cash flows. In August 2014, the Financial Accounting Standards Board issued authoritative guidance which provides guidance on determining when and how to disclose going-concern uncertainties in the financial statements. The new standard requires management to perform interim and annual assessments of an entity’s ability to continue as a going concern within one year of the date the financial statements are issued. This update is effective for fiscal years, and interim periods within those years, beginning on or after December 15, 2016, with early adoption permitted. The Company is evaluating the new guidance and plan to provide additional information about its expected impact at a future date. In May 2014, the Financial Accounting Standards Board issued authoritative guidance which clarifies the principles used to recognize revenue for all entities. The new guidance requires companies to recognize revenue when it transfers goods or services to a customer in an amount that reflects the consideration to which a company expects to be entitled. The guidance is effective for annual and interim periods beginning after December 15, 2017. The guidance allows for either a “full retrospective” adoption or a “modified retrospective” adoption, however early adoption is not permitted. The Company is currently evaluating the impact the adoption of this guidance will have on its consolidated financial statements.

During 2014, APX issued an additional $100.0 million of 2020 notes at a price of 102.00%. In October 2015, APX issued $300.0 million aggregate principal amount of 8.875% senior secured notes due 2022 (the “2022 notes” and, together with the 2019 notes and the 2020 notes, the “notes”), pursuant to a note purchase agreement dated as of October 19, 2015 in a private placement exempt from registration under the U.S. Securities Act of 1933, as amended (the “Securities Act”). The 2022 notes will mature on December 1, 2022, unless on September 1, 2020 (the 91st day prior to the maturity of the 2020 notes) more than an aggregate principal amount of $190.0 million of such 2020 notes remain outstanding or have not been refinanced as permitted under the note purchase agreement for the 2022 notes, in which case the 2022 notes will mature on September 1, 2020. The 2022 notes are secured, on a pari passu basis, by the collateral securing obligations under the 2019 notes and the revolving credit facilities, in each case, subject to certain exceptions and permitted liens. The notes are fully and unconditionally guaranteed, jointly and severally by APX and each of APX’s existing restricted subsidiaries that guarantee indebtedness under APX’s revolving credit facility or our other indebtedness. Interest accrues at the rate of 6.375% per annum for the 2019 notes, 8.75% per annum for the 2020 notes and 8.875% per annum for the 2022 notes. Interest on the notes is payable semiannually in arrears on each June 1 and December 1. After December 1, 2015, APX may redeem the 2019 and 2020 notes at the prices and on the terms specified in the applicable indenture. After December 1, 2018, APX may redeem the 2022 notes at the prices and on the terms specified in the note purchase agreement for the 2022 notes. Revolving Credit Facility On November 16, 2012, APX entered into a $200.0 million senior secured revolving credit facility, with a five year maturity. In addition, APX may request one or more term loan facilities, increased commitments under the revolving credit facility or new revolving credit commitments, in an aggregate amount not to exceed $225.0 million. Availability of such incremental facilities and/or increased or new commitments will be subject to certain customary conditions. On June 28, 2013, APX amended and restated the credit agreement to provide for a new repriced tranche of revolving credit commitments with a lower interest rate. Nearly all of the existing tranches of revolving credit commitments was terminated and converted into the repriced tranche, with the unterminated portion of the existing tranche continuing to accrue interest at the original rate. 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. 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 $247.5 million and Series C Revolving Commitments of approximately $20.8 million is currently 2.0% per annum and (b) under the Series B Revolving Commitments of approximately $21.2 million is currently 3.0% and (2)(a) the applicable margin for LIBOR rate-based borrowings (a) under the Series A Revolving Commitments and Series C Revolving Commitments is currently 3.0% per annum and (b) under the Series B Revolving Commitments is currently 4.0%. The applicable margin for borrowings under the revolving credit facility is subject to one step-down of 25 basis points based on APX meeting a consolidated first lien net leverage ratio test at the end of each fiscal quarter. Outstanding borrowings under the amended and restated revolving credit facility are allocated on a pro-rata basis between each Series based on the total Revolving Commitments. In addition to paying interest on outstanding principal under the revolving credit facility, APX is required to pay a quarterly commitment fee (which will be subject to one interest rate step-down of 12.5 basis points, based on APX meeting a consolidated first lien net leverage ratio test) to the lenders under the revolving credit facility in respect of the unutilized commitments thereunder. APX also pays customary letter of credit and agency fees. APX is not required to make any scheduled amortization payments under the revolving credit facility. The principal amount outstanding under the revolving credit facility will be due and payable in full on (1) with respect to the non-extended commitments under the Series C Revolving Credit Facility, November 16, 2017 and (2) with respect to the extended commitments under the Series A Revolving Credit Facility and Series B Revolving Credit Facility, March 31, 2019.

Blackstone Advisory Partners L.P. (“Blackstone Partners”) participated as one of the initial purchasers of the 2020 notes in each of the May 31, 2013 and December 13, 2013 offerings and received approximately $0.2 million and $0.3 million in fees, respectively, at the time of closing. On July 1, 2014, APX issued an additional $100.0 million of 2020 notes. In connection with the issuance, Blackstone Partners participated as one of the initial purchasers of the 2020 notes and received approximately $0.1 million in fees at the time of closing. On October 19, 2015, APX issued $300.0 million aggregate principal amount of 8.875% senior secured notes due 2022 (the “2022 notes’), pursuant to a note purchase agreement dated as of October 19, 2015 in a private placement exempt from registration under the U.S. Securities Act of 1933, as amended (the “Securities Act”). The 2022 notes are fully and unconditionally guaranteed, jointly and severally, on a senior secured basis, by APX and each of APX’s existing restricted subsidiaries that guarantee indebtedness under APX’s revolving credit facility and APX’s existing senior secured notes and senior unsecured notes. APX’s existing and future foreign subsidiaries are not expected to guarantee the 2022 notes. The 2022 notes are secured, on a pari passu basis, by the collateral securing obligations under the APX’s existing senior secured notes and the revolving credit facilities, in each case, subject to certain exceptions and permitted liens. Interest accrues at the rate of 6.375% per annum for the 2019 notes, 8.75% per annum for the 2020 notes and 8.875% per annum for the 2022 notes. Interest on the notes is payable semiannually in arrears on each June 1 and December 1. After December 1, 2015, APX may redeem the notes at the prices and on the terms specified in the applicable indenture. After December 1, 2018, APX may redeem the 2022 notes at the prices and on the terms specified in the note purchase agreement for the 2022 notes. Revolving Credit Facility On November 16, 2012, APX Group Holdings, Inc. and the other guarantors entered into a revolving credit facility in the aggregate principal amount of $200.0 million. On June 28, 2013, the Company amended and restated the credit agreement to provide for a new repriced tranche of revolving credit commitments with a lower interest rate. Nearly all of the existing tranches of revolving credit commitments were terminated and converted into the repriced tranche, with the unterminated portion of the existing tranche continuing to accrue interest at the original rate. 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. Borrowings under the revolving credit facility 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 (1)(a) under the repriced tranche is currently 2.0% per annum and (b) under the former tranche is currently 3.0% and (2)(a) the applicable margin for LIBOR rate-based borrowings (a) under the repriced tranche is currently 3.0% per annum and (b) under the former tranche 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 the Company 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, the Company is required to pay a quarterly commitment fee of 0.50% (which will be subject to one step-down based on the Company meeting a consolidated first lien net leverage ratio test) to the lenders under the revolving credit facility in respect of the unutilized commitments thereunder. The Company also pays customary letter of credit and agency fees. APX is not required to make any scheduled amortization payments under the revolving credit facility. The principal amount outstanding under the revolving credit facility will be due and payable in full on (1) with respect to the non-extended commitments under the Series C Revolving Credit Facility, November 16, 2017 and (2) with respect to the extended commitments under the Series A Revolving Credit Facility and Series B Revolving Credit Facility, March 31, 2019. As of December 31, 2015, we had $264.4 million of availability to incur secured indebtedness under the revolving credit facility (after giving effect to $5.0 million of outstanding letters of credit and $20.0 million of borrowings).

The Company could make up to $1.8 million in additional investments in the Investee, subject to the achievement of certain technology development milestones. These additional investments are expected to occur through December 31, 2016. The Company has determined that the arrangement with the Investee constitutes a variable interest. The Company is not required to consolidate the results of the Investee as the Company is not the primary beneficiary. On February 19, 2014, the Company invested $3.0 million in a convertible note (“Convertible Note”) of a privately held company (“Investee”) not affiliated with the Company. The Convertible Note had a stated maturity date of February 19, 2015 and bore interest equal to the greater of (a) 0.5% or (b) annual interest rates established for federal income tax purposes by the Internal Revenue Service. The outstanding principal and accrued interest balance of the Convertible Note converted to preferred stock (“preferred stock”) of the Investee on August 29, 2014, under the terms of the agreement. The Company performs impairment analyses of its cost based investments annually, or more often, when events occur or circumstances change that would, more likely than not, reduce the fair value of the investment below its carrying value. When indicators of impairment do not exist and certain accounting criteria are met, the Company evaluates impairment using a qualitative approach. As of December 31, 2015, no indicators of impairment existed associated with these cost based investments.

Facility Fire	NOTE 12—FACILITY FIRE On March 18, 2014, a fire occurred at a facility leased by the company in Lindon, Utah. This facility contained the Company’s primary inventory warehouse and call center operations. Through December 31, 2015, the Company recognized gross expenses related to the fire of $8.3 million, which were primarily related to impairment of damaged assets and recovery costs to maintain business continuity. As of December 31, 2015, the Company had also received insurance recoveries of $8.8 million, related to the fire damage, $3.0 million of which related to the reconstruction of the facility damaged by the fire, and is included within the Company’s cash flows from investing activities in the consolidated statement of cash flows for the year ended December 31, 2015. Insurance recoveries associated with the reconstruction of the damaged facility exceeded its net book value by $0.5 million. These excess insurance recoveries were included in other income as of December 31, 2014. All probable insurance recoveries have been received as of December 31, 2015. Expenses in excess of insurance recoveries during the year ended December 31, 2015 were immaterial.

Income Tax Disclosure [Abstract]
Income Taxes	NOTE 8—INCOME TAXES In order to determine the quarterly provision for income taxes, the Company uses an estimated annual effective tax rate, which is based on expected annual income and statutory tax rates in the various jurisdictions in which the Company operates. Certain significant or unusual items are separately recognized in the quarter during which they occur and can be a source of variability in the effective tax rates from quarter to quarter. The Company’s effective income tax rate for the three months ended March 31, 2016 was approximately negative 2.55%. In computing income tax expense, the Company estimates its annual effective income tax rate jurisdiction by jurisdiction and entity by entity for which tax attributes must be separately considered for the calendar year ending December 31, 2015, excluding discrete items. Each jurisdictional or entity estimated annual tax rate is applied to actual year-to-date pre-tax book income (loss) of each jurisdiction or entity. The Company had no discrete items that affected the calculated income tax benefit or expense for the three months ended March 31, 2016. Both the 2016 and 2015 effective tax rates are less than the statutory rate primarily due to the combination of not recognizing benefit for expected pre-tax losses of the US jurisdiction and recognizing current state income tax expense for minimum state taxes. For 2016, the Company expects to realize a loss before income taxes and expects to record a full valuation allowance against the net deferred tax assets of the consolidated group within the US, Canadian and New Zealand jurisdictions. The Company has recorded tax expense for state and local taxes. A valuation allowance is required when there is significant uncertainty as to the ability to realize the deferred tax assets. Because the realization of the deferred tax assets related to the Company’s net operating losses (NOLs) is dependent upon future income related to domestic and foreign jurisdictional operations that have historically generated losses, management determined that the Company continues to not meet the “more likely than not” threshold that those NOLs will be realized. Accordingly, a valuation allowance is required. A similar history of losses is present in the Company’s Canadian and New Zealand jurisdictions. However, as of March 31, 2016, the deferred tax assets related to the Company’s Canadian and New Zealand jurisdictions’ NOLs are offset by existing deferred income tax liabilities resulting in a net deferred tax liability position in both jurisdictions.

The current portion of the net deferred tax liability was approximately $0 and $36,000 at December 31, 2015 and 2014, respectively, and is included in accrued expenses and other liabilities on the Company’s Consolidated Balance Sheet as of December 31, 2014. The Company had net operating loss carryforwards as follows (in thousands): December 31, 2015 2014 Net operating loss carryforwards: United States $ 1,695,386 $ 1,355,632 State 1,338,742 1,301,462 Canada 28,629 30,688 New Zealand 5,518 4,203 U.S. and state net operating loss carryforwards will begin to expire in 2026, if not used. Included in both the U.S. and state net operating loss carryforwards are approximately $11.5 million and $11.5 million at December 31, 2015 and 2014, respectively of net operating loss carryforwards for which a benefit will be recorded in Additional Paid in Capital when realized. The Company had U.S. research and development credits of approximately $41,000 at December 31, 2015, and December 31, 2014, which begin to expire in 2030. Canadian net operating loss carryforwards will begin to expire in 2029. Realization of the Company’s net operating loss carryforwards and tax credits is dependent on generating sufficient taxable income prior to their expiration. Although a portion of these carryforwards are subject to the provisions of Internal Revenue Code Section 382, we have not performed a formal study to determine the amount of the limitation. The use of the net operating loss carryforwards may have additional limitations resulting from future ownership changes or other factors under Section 382 of the Internal Revenue Code. The Company has considered and weighed the available evidence, both positive and negative, to determine whether it is more-likely-than-not that some portion, or all, of the deferred tax assets will not be realized. Based on available information, management does not believe it is more likely than not that its deferred tax assets will be utilized. Accordingly, the Company has established a valuation allowance to the extent of and equal to the net deferred tax assets. The Company recorded a valuation allowance for U.S. deferred tax assets of approximately $234.8 million and $139.4 million at December 31, 2015 and 2014, respectively. In addition to the change in valuation allowance from operations, the valuation allowance changes include impact of acquisition and disposition related items. As of December 31, 2015, the Company’s income tax returns for the tax years 2012 through 2015, remain subject to examination by the Internal Revenue Service and state authorities. The Company’s income tax returns for the years ended December 31, 2012 and December 31, 2013 are currently under examination by the Internal Revenue Service.

Stock-Based Compensation	NOTE 9—STOCK-BASED COMPENSATION 313 Incentive Units The Company’s indirect parent, 313 Acquisition LLC (“313”), which is owned by Blackstone, has authorized the award of profits interests, representing the right to share a portion of the value appreciation on the initial capital contributions to 313 (“Incentive Units”). In March 2015, a total of 4,315,106 Incentive Units previously issued to the Company’s Chief Executive Officer and President were voluntarily relinquished. The Company recorded all unrecognized stock-based compensation associated with such Incentive Units at the time the Incentive Units were relinquished. As of March 31, 2016, 73,962,836 Incentive Units had been awarded to current and former members of senior management and a board member, of which 42,169,456 were outstanding to the Company’s Chief Executive Officer and President. The Incentive Units are subject to time-based and performance-based vesting conditions, with one-third subject to ratable time-based vesting over a five year period and two-thirds subject to the achievement of certain investment return thresholds by The Blackstone Group, L.P. and its affiliates (“Blackstone”). The Company has not recorded any expense related to the performance-based portion of the awards, as the achievement of the vesting condition is not yet deemed probable. The fair value of stock-based awards is measured at the grant date and is recognized as expense over the employee’s requisite service period. The grant date fair value was determined using a Monte Carlo simulation valuation approach with the following assumptions: expected volatility of 65%; expected exercise term from 5 to 6.0 years; and risk-free rate of 1.88% to 2.03%. Vivint Stock Appreciation Rights The Company’s subsidiary, Vivint Group, Inc. (“Vivint Group”), has awarded Stock Appreciation Rights (“SARs”) to various levels of key employees, pursuant to an omnibus incentive plan. The purpose of the SARs is to attract and retain personnel and provide an opportunity to acquire an equity interest of Vivint Group. The SARs are subject to time-based and performance-based vesting conditions, with one-third subject to ratable time-based vesting over a five year period and two-thirds subject to the achievement of certain investment return thresholds by 313. The Company has not recorded any expense related to the performance-based portion of the awards, as the achievement of the vesting condition is not yet deemed probable. In connection with this plan, 17,558,111 SARs were outstanding as of March 31, 2016. In addition, 53,621,143 SARs have been set aside for funding incentive compensation pools pursuant to long-term incentive plans established by the Company. On April 1, 2015, a new plan was created and all issued and outstanding Vivint, Inc. (“Vivint”) SARs were re-granted and all reserved SARs were converted under the new Vivint Group plan. The Company assessed the conversion of the SARs as a modification of equity instruments. The restructuring did not change the fair value of the existing awards and as such, no incremental compensation expense was incurred as a result of the restructuring. The fair value of the Vivint Group awards is measured at the grant date and is recognized as expense over the employee’s requisite service period. The fair value is determined using a Black-Scholes option valuation model with the following assumptions: expected volatility varies from 65% to 70%, expected dividends of 0%; expected exercise term between 1.91 and 6.50 years; and risk-free rates between 0.52% and 2.07%. Due to the lack of historical exercise data, the Company used the simplified method in determining the estimated exercise term, for all Vivint Group awards. Wireless Stock Appreciation Rights The Company’s subsidiary, Vivint Wireless, has awarded SARs to various key employees, pursuant to an omnibus incentive plan. The purpose of the SARs is to attract and retain personnel and provide an opportunity to acquire an equity interest of Vivint Wireless. The SARs are subject to a five year time-based ratable vesting period. In connection with this plan, 17,500 SARs were outstanding as of March 31, 2016. The Company does not intend to issue any additional Wireless SARs. The fair value of the Vivint Wireless awards is measured at the grant date and is recognized as expense over the employee’s requisite service period. The fair value is determined using a Black-Scholes option valuation model with the following assumptions: expected volatility of 65%, expected dividends of 0%; expected exercise term between 5.97 and 6.46 years; and risk-free rates between 1.73% and 1.81%. Due to the lack of historical exercise data, the Company used the simplified method in determining the estimated exercise term, for all Vivint Wireless awards. Stock-based compensation expense in connection with all stock-based awards is presented as follows (in thousands): Three Months Ended March 31, 2016 2015 Operating expenses $ 14 $ 14 Selling expenses (294 ) 33 General and administrative expenses 338 742 Total stock-based compensation $ 58 $ 789 Stock-based compensation expense presented in selling expenses was negative for the quarter due to a retrospective adjustment in the grant-date fair value of a series of stock-based awards.

On July 20, 2015, Vivint entered into a letter agreement with Solar and SunEdison, Inc., a Delaware corporation (“SunEdison”) in connection with Solar’s entrance into an Agreement and Plan of Merger with SunEdison and the other parties thereto pursuant to which a newly-formed wholly-owned subsidiary of SunEdison will merge with and into Solar, with Solar surviving as a wholly-owned subsidiary of SunEdison (the “Solar Merger”). Pursuant to the Letter Agreement, the parties agreed, among other things, to (i) subject to the finalization and execution of a transitional trademark license regarding Solar’s continued use of the “Vivint Solar” trademark for a limited duration for purposes of phase-out use following the consummation of the Solar Merger, terminate the Trademark License Agreement between Vivint Solar Licensing, LLC and Solar, dated September 30, 2014, (ii) terminate the Product Development and Supply Agreement between Vivint Solar Developer, LLC and Vivint, dated September 30, 2014, (iii) terminate the covenants of non-competition in the Non-Competition Agreement between Solar and Vivint, dated September 30, 2014, in each case effective as of the consummation of the Solar Merger and (iv) terminate Schedule 3 to the Marketing and Customer Relations Agreement between Vivint Solar Developer, LLC and Vivint, dated September 30, 2014. The parties also agreed to negotiate in good faith regarding the termination or amendment of certain other agreements between Solar, Vivint, and certain of their respective subsidiaries. On March 7, 2016, Solar terminated the Agreement and Plan of Merger relating to the Solar Merger. Accordingly, pursuant to its terms, the Letter Agreement also terminated on March 7, 2016. Other Related-party Transactions On September 3, 2014, APX paid a dividend in the amount of $50.0 million to Holdings, its sole stockholder, which in turn paid a dividend in the amount of $50.0 million to its stockholders. The Company incurred additional expenses during the years ended December 31, 2015, 2014 and 2013 of approximately $2.5 million, $3.1 million, $3.1 million, respectively, for other related-party transactions including contributions to the charitable organization Vivint Gives Back, legal fees, and services. Accrued expenses and other current liabilities at December 31, 2015 and 2014, included a payable to Vivint Gives Back for $1.7 million and $1.3 million, respectively. On November 16, 2012, the Company was acquired by an investor group comprised of certain investment funds affiliated with Blackstone Capital Partners VI L.P., and certain co-investors and management investors through certain mergers and related reorganization transactions (collectively, the “Merger”). At the time of the Merger, a portion of the purchase price was placed in escrow to cover potential adjustments to the total purchase consideration associated with certain indemnities and adjustments to tangible net worth. In April 2015, the parties to the Merger reached an agreement regarding the amount to be paid from escrow. As the Company had previously recorded expenses related to these pre-merger costs, this agreement resulted in a reduction to general and administrative expenses of $12.2 million, with the offset to additional paid-in capital. In connection with the Merger, the Company entered into a support and services agreement with Blackstone Management Partners L.L.C. (“BMP”), an affiliate of Blackstone. Under the support and services agreement, the Company paid BMP, at the closing of the Merger, a transaction fee of approximately $20 million as consideration for BMP’s performance of due diligence investigations, financial and structural analysis, providing corporate strategy and other advice and negotiation assistance in connection with the Merger. In addition, the Company engaged 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 of approximately $3.6 million, $3.2 million and $2.9 million during the years ended December 31, 2015, 2014 and 2013, respectively, in connection with this agreement. Under the support and services agreement, the Company also engaged BMP to arrange for Blackstone’s portfolio operations group to provide support services customarily provided by Blackstone’s portfolio operations group to Blackstone’s private equity portfolio companies of a type and amount determined by such portfolio services group to be warranted and appropriate. BMP will invoice the Company for such services based on the time spent by the relevant personnel providing such services during the applicable period but in no event shall the Company be obligated to pay more than $1.5 million during any calendar year. Long-term investments and other assets, includes amounts due for non-interest bearing advances made to employees that are expected to be repaid in excess of one year. Amounts due from employees as of both December 31, 2015 and 2014, amounted to approximately $0.3 million. As of December 31, 2015 and 2014, this amount was fully reserved. Prepaid expenses and other current assets at December 31, 2015 and 2014 included a receivable for $0.2 million and $0.3 million, respectively, from certain members of management in regards to their personal use of the corporate jet. From time to time, the Company does business with a number of other companies affiliated with Blackstone. Transactions involving related parties cannot be presumed to be carried out at an arm’s-length basis.

These segments were managed and evaluated separately by management due to the differences in their products and services. The primary source of revenue for the Vivint segment is generated through monitoring services provided to subscribers, in accordance with their subscriber contracts.

Accounting Changes and Error Corrections [Abstract]
Retrospective Adoption Of ASU 2015-03	NOTE 20—RETROSPECTIVE ADOPTION OF ASU 2015-03 As discussed in Note 2, “Significant Accounting Policies,” ASU 2015-03 simplifies the presentation of debt issuance costs by requiring that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. As a result of the retrospective adoption of ASU 2015-03 effective January 1, 2016, deferred financing costs, net of approximately $40.2 million and $48.1 million previously classified as an asset within Deferred Financing Costs, net were reclassified to reduce the related debt liabilities within Notes Payable, net as of December 31, 2015 and 2014, respectively. Accordingly, the accompanying Consolidated Balance Sheets; Note 2, “Significant Accounting Policies”; Note 6, “Long-Term Debt”; Note 17, “Segment Reporting and Business Concentrations”; and Note 19, “Guarantor and Non-Guarantor Supplemental Financial Information” have been updated. Additionally, Note 21, “Subsequent Events” has been added. No other updates have been made to what was previously disclosed in the consolidated financial statements in the Company’s 2015 Form 10-K that was filed with the Securities Exchange Commission on March 10, 2016 other than the above mentioned updates and updates to our Report of Independent Registered Accounting Firm to reflect a dual dated opinion as a result of these updates.

(“Parent”), a parent company of the Company, completed the issuance and sale to certain investors of a series of preferred stock in a private placement exempt from registration under the Securities Act. On April 29, 2016, Parent contributed the net proceeds of $69.8 million from such issuance and sale to the Company as an equity contribution. On May 26, 2016, APX Group, Inc. (the “Issuer”), a wholly-owned subsidiary of the Company issued $500.0 million aggregate principal amount of 7.875% senior secured notes due 2022 (the “outstanding 2022 notes”), pursuant to an indenture dated as of May 26, 2016 among the Issuer, the guarantors party thereto and Wilmington Trust, National Association, as trustee and collateral agent. The outstanding 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 outstanding 2022 notes are secured, on a pari passu basis, by the collateral securing obligations under the notes and the revolving credit facilities, in all cases, subject to certain exceptions and permitted liens. The Issuer used a portion of the net proceeds from the offering of the outstanding 2022 notes to repurchase approximately $235 million aggregate principal amount of its outstanding 6.375% Senior Secured Notes due 2019 and 8.875% Senior Secured Notes due 2022 in privately negotiated transactions and repay borrowings under its existing revolving credit facility.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation During the three months ended March 31, 2015, the Company recorded certain out-of-period adjustments totaling $2.0 million, primarily associated with the timing of the recognition of deferred revenue related to 2014 recurring monitoring services. As a result of these adjustments, recurring revenues increased for the three months ended March 31, 2015 and deferred revenue decreased by $2.0 million, respectively. The Company evaluated the impact of the out-of-period adjustments and determined that they are immaterial to the unaudited condensed consolidated financial statements for the three months ended March 31, 2015.	Basis of Presentation The Company has prepared the accompanying consolidated financial statements pursuant to generally accepted accounting principles in the United States (“GAAP”). Preparing financial statements requires the Company to make estimates and assumptions that affect the amounts that are reported in the consolidated financial statements and accompanying disclosures. Although these estimates are based on the Company’s best knowledge of current events and actions that the Company may undertake in the future, actual results may be different from the Company’s estimates. The results of operations presented herein are not necessarily indicative of the Company’s results for any future period. During the year ended December 31, 2015, the Company recorded certain out-of-period adjustments totaling $2.0 million, primarily associated with the timing of the recognition of deferred revenue related to 2014 recurring monitoring services. As a result of these adjustments, recurring revenues increased for the year ended December 31, 2015 and deferred revenue decreased by $2.0 million, respectively. The Company evaluated the impact of the out-of-period adjustments and determined that they are immaterial to the consolidated financial statements for the year ended December 31, 2015.

Revenue Recognition	Revenue Recognition— Recurring revenue for the Company’s subscriber contracts is billed in advance, generally monthly, pursuant to the terms of subscriber contracts and recognized ratably over the service period. Costs of providing ongoing recurring services are expensed in the period incurred. Service and other sales revenue is recognized as services are provided or when title to the products and equipment sold transfers to the customer. Contract fulfillment revenue, included in service and other sales, is recognized when payment is received from customers who cancel their contract in-term. Revenue from sales of products that are not part of the basic equipment package is generally recognized upon delivery of products. Activation fees represent upfront one-time charges billed to subscribers at the time of installation and are deferred. These fees are recognized over the estimated customer life of 12 years using a 150% declining balance method, which converts to a straight-line methodology after approximately five years to approximate the anticipated life of the customer.

Through the date of the 2GIG Sale, service and other sales revenue included net recurring services revenue, which was based on back-end services provided by Alarm.com for all panels sold to distributors and direct-sell dealers and subsequently placed in service at end-user locations. The Company received a fixed monthly amount from Alarm.com for each system installed with non-Vivint customers that used the Alarm.com platform.
Subscriber Acquisition Costs	Subscriber Acquisition Costs On the condensed consolidated statement of cash flows, subscriber acquisition costs that are comprised of equipment and related installation costs purchased for or used in subscriber contracts in which the Company retains ownership to the equipment are classified as investing activities and reported as “Subscriber acquisition costs—company owned equipment”. All other subscriber acquisition costs are classified as operating activities and reported as “Subscriber acquisition costs—deferred contract costs” on the condensed consolidated statements of cash flows as these assets represent deferred costs associated with customer contracts.

Long-lived Assets and Intangibles	Long-lived Assets and Intangibles During the fiscal quarter ended March 31, 2016, the Company adopted guidance issued by the Financial Accounting Standards Board (“FASB”) which provides new standards to determine whether a cloud computing arrangement includes a software license. The guidance requires the company to determine if an internal use software obtained in a cloud hosting arrangement contains a contractual right to take possession of the software and if it is feasible to either run the software on internal hardware or contract with an unrelated vendor to host the software. If both criteria are met, the company will consider the arrangement to include a software license and classify the purchase as an intangible. The company has elected to adopt the guidance prospectively to all arrangements entered into or materially modified after the beginning of 2016. The company did not enter into, or modify, any material arrangements during the fiscal quarter ended March 31, 2016.	Long-lived Assets and Intangibles

Fair Value Measurement	Fair Value Measurement 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 three months ended March 31, 2016 and 2015. 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.

Foreign Currency Translation and Other Comprehensive Income	Foreign Currency Translation and Other Comprehensive Income When intercompany foreign currency transactions between entities included in the consolidated financial statements are of a long term investment nature (i.e., those for which settlement is not planned or anticipated in the foreseeable future) foreign currency translation adjustments resulting from those transactions are included in stockholders’ deficit as accumulated other comprehensive loss. When intercompany transactions are deemed to be of a short term nature, translation adjustments are required to be included in the condensed consolidated statement of operations. Translation gains related to intercompany balances were $4.7 million and $0 for the three months ended March 31, 2016 and 2015, respectively.	Foreign Currency Translation and Other Comprehensive Income When intercompany foreign currency transactions between entities included in the consolidated financial statements are of a long term investment nature (i.e., those for which settlement is not planned or anticipated in the foreseeable future) foreign currency translation adjustments resulting from those transactions are included in stockholders’ (deficit) equity as accumulated other comprehensive loss. When intercompany transactions are deemed to be of a short term nature, translation adjustments are required to be included in the consolidated statement of operations. Beginning in July 2015, we determined that settlement of these intercompany balances was anticipated and therefore these balances are not considered to be long-term investments and any subsequent translation gains or losses are recorded in income. Translation losses related to intercompany balances were $9.4 million, $0 and $0 for the years ended December 31, 2015, 2014, and 2013, respectively.

New Accounting Pronouncements	New Accounting Pronouncements In March 2016, the FASB issued ASU 2016-08 to clarify the implementation guidance on principal versus agent considerations as it relates to Revenue from Contracts with Customers (Topic 606). This update is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017 and must be applied retrospectively, with early adoption permitted. The Company is evaluating the new guidance and plans to provide additional information about its expected impact at a future date. In March 2016, the FASB issued ASU 2016-07 which eliminates the requirement to retroactively adopt the equity method of accounting when an investment qualifies for use of the equity method as a result of an increase in the level of ownership interest or degree of influence. This update is effective for fiscal years, and interim periods within those years, beginning after December 15, 2016 and must be applied prospectively, with early adoption permitted. The Company plans to adopt this update on the effective date and the adoption is not expected to materially impact the consolidated financial statements. In March 2016, the FASB issued ASU 2016-06 to clarify the assessment of contingent put and call options in debt instruments as it relates to Derivatives and Hedging (Topic 815). The amendments in this update clarify the requirements for assessing whether contingent call (put) options that can accelerate the payment of principal on debt instruments are clearly and closely related to their debt hosts. An entity performing the assessment under the amendments in this update is required to assess the embedded call (put) options solely in accordance with the four-step decision sequence. This update is effective for fiscal years, and interim periods within those years, beginning after December 15, 2016 and must be applied using a modified retrospective approach, with early adoption permitted. The Company plans to adopt this update on the effective date and is not expected to materially impact the consolidated financial statements. In February 2016, the FASB issued ASU 2016-02 to increase transparency and comparability among organizations as it relates to lease assets and lease liabilities. The update requires that lease assets and lease liabilities be recognized on the balance sheet, and that key information about leasing arrangements be disclosed. Prior to this update, GAAP did not require operating leases to be recognized as lease assets and lease liabilities on the balance sheet. This update is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018 and must be applied using a modified retrospective approach, with early adoption permitted. The Company is evaluating the new guidance and plans to provide additional information about its expected impact at a future date. In January 2016, the FASB issued ASU 2016-01 to address certain aspects of the recognition, measurement, presentation, and disclosure of financial instruments. The main provisions of this update require equity investments to be measured at fair value with changes in fair value recognized in earnings, allows a company to value equity investments without a readily determined fair value at cost, less any impairments, and simplifies the assessment of impairments of equity investments without a readily determinable fair value by requiring a qualitative assessment. This update is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017. An entity should apply the amendments by means of a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption. The amendments related to equity securities without readily determinable fair values (including disclosure requirements) should be applied prospectively to equity investments that exist as of the date of adoption of the Update. Early adoption is permitted. The Company is evaluating the new guidance and plans to provide additional information about its expected impact at a future date. In July 2015, the FASB issued ASU 2015-11 to simplify the measurement of inventory. Prior to this update, GAAP required the measurement of inventory at the lower of cost or market, where market could be replacement cost, net realizable value, or net realizable value less an approximately normal profit margin. This update requires that an entity measure inventory at the lower of cost or net realizable value, where net realizable value is the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. This guidance is effective for fiscal years beginning after December 15, 2016, and for interim periods within those fiscal years and should be applied prospectively, with early adoption permitted. The Company plans to adopt this update on the effective date and the adoption is not expected to impact the consolidated financial statements. In May 2014, the FASB issued ASU 2014-09 which clarifies the principles used to recognize revenue for all entities. The new guidance requires companies to recognize revenue when it transfers goods or services to a customer in an amount that reflects the consideration to which a company expects to be entitled. Pursuant to ASU 2015-14, the guidance is effective for annual and interim periods beginning after December 15, 2017. The guidance allows for either a “full retrospective” adoption or a “modified retrospective” adoption, with early adoption permitted. The Company is evaluating the new guidance and plans to provide additional information about its expected impact at a future date.	New Accounting Pronouncements In July 2015, the Financial Accounting Standards Board issued authoritative guidance to simplify the measurement of inventory. Prior to this update, generally accepted accounting principles required the measurement of inventory at the lower of cost or market, where market could be replacement cost, net realizable value, or net realizable value less an approximately normal profit margin. This update requires that an entity measure inventory at the lower of cost or net realizable value, where net realizable value is the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. This guidance is effective for fiscal years beginning after December 15, 2016, and for interim periods within fiscal years beginning after December 15, 2017 and should be applied prospectively, with early adoption permitted. The Company plans to adopt this update on the effective date and is not expected to materially impact the consolidated financial statements. In May 2015, the Financial Accounting Standards Board issued authoritative guidance related to customer’s accounting for fees paid in a cloud computing arrangement and is issued in an attempt to simplify existing generally accepted accounting principles. The update provides guidance to help entities determine whether a cloud computing arrangement includes a software license. This guidance is effective for fiscal years beginning after December 15, 2015, and for interim periods within fiscal years beginning after December 15, 2016 with early adoption permitted. The Company plans to adopt this update on the effective date and is not expected to materially impact the consolidated financial statements. In April 2015, the Financial Accounting Standards Board issued authoritative guidance (“ASU 2015-03”) to simplify the presentation of debt issuance costs. This update requires debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The guidance is effective for fiscal years beginning after December 15, 2015, and for interim periods within fiscal years beginning after December 15, 2016. Effective January 1, 2016, the Company adopted this standard resulting in a retrospective reduction to deferred financing costs, net by $40.2 million and $48.1 million as of December 31, 2015 and December 31, 2014, respectively, with a corresponding decrease to notes payable, net. This update does not impact the consolidated statements of operations, consolidated statements of comprehensive loss or consolidated statements of cash flows. In August 2014, the Financial Accounting Standards Board issued authoritative guidance which provides guidance on determining when and how to disclose going-concern uncertainties in the financial statements. The new standard requires management to perform interim and annual assessments of an entity’s ability to continue as a going concern within one year of the date the financial statements are issued. This update is effective for fiscal years, and interim periods within those years, beginning on or after December 15, 2016, with early adoption permitted. The Company is evaluating the new guidance and plan to provide additional information about its expected impact at a future date. In May 2014, the Financial Accounting Standards Board issued authoritative guidance which clarifies the principles used to recognize revenue for all entities. The new guidance requires companies to recognize revenue when it transfers goods or services to a customer in an amount that reflects the consideration to which a company expects to be entitled. The guidance is effective for annual and interim periods beginning after December 15, 2017. The guidance allows for either a “full retrospective” adoption or a “modified retrospective” adoption, however early adoption is not permitted. The Company is currently evaluating the impact the adoption of this guidance will have on its consolidated financial statements.
