	APX Group Holdings, Inc. (“Holdings” or “Parent”), and its wholly-owned subsidiaries, (collectively the “Company”), is one of the largest residential security and home automation companies in North America. The Company is engaged in the sale, installation, servicing and monitoring of electronic home security and automation systems in the United States and Canada.
	On November 16, 2012, APX Group, Inc. (“APX”), 2GIG Technologies, Inc. (“2GIG”), and their respective subsidiaries were 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 (collectively, the “Investors”). This stock acquisition was accomplished through certain mergers and related reorganization transactions (collectively, the “Merger”) pursuant to which each of APX and 2GIG, and their respective subsidiaries became indirect wholly-owned subsidiaries of 313 Acquisition LLC, an entity wholly-owned by the Investors.
	As a result of the Merger, Vivint, Inc. and its wholly-owned subsidiaries and 2GIG and its wholly-owned subsidiaries collectively became wholly-owned by APX Group, Inc., which is wholly-owned by APX Group Holdings, Inc., which is wholly-owned by APX Parent Holdco, Inc., which is wholly owned by 313 Acquisition, LLC.

SIGNIFICANT ACCOUNTING POLICIES

NOTE 2—SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation—As a result of the Merger, the consolidated financial statements are presented on two bases of accounting and are not necessarily comparable: January 1, 2011 through November 16, 2012 (the “Predecessor Period” or “Predecessor” as context requires) and November 17, 2012 through December 31, 2013 (the “Successor Period” or “Successor” as context requires), which relate to the period preceding the Merger and the period succeeding the Merger, respectively. The audited consolidated financial statements for the Predecessor Period are presented for APX Group, Inc. and its wholly-owned subsidiaries, including variable interest entities. The audited consolidated financial statements for the Successor Period reflect the Merger presenting the financial position and results of operations of APX Group Holdings, Inc. and its wholly-owned subsidiaries. The financial position and results of operations of the Successor are not comparable to the financial position and results of operations of the Predecessor due to the Merger and the basis of presentation of purchase accounting as compared to historical cost in accordance with Accounting Standards Codification (“ASC”) 805 Business Combinations.

The consolidated financial statements for the Predecessor and Successor include the financial position and results of operations of the following entities:

The Successor and Predecessor Period include substantially the same operating entities except that Vivint Solar, Inc. and its subsidiaries (“Solar”) is not included in the Successor Period since Solar is separately owned and is no longer a consolidated variable interest entity.

Principles of Consolidation—The accompanying Successor consolidated financial statements include the accounts of APX Group Holdings, Inc. and its subsidiaries, including 2GIG as a wholly-owned subsidiary through April 1, 2013. The accompanying Predecessor consolidated financial statements include APX Group, Inc. and its subsidiaries, and 2GIG and Solar, which were variable interest entities (or “VIE’s”) prior to the Merger (See Note 7). All significant intercompany balances and transactions have been eliminated in consolidation.

The financial information presented in the accompanying consolidated financial statements reflects the financial position and operating results of Smart Grid as discontinued operations (See Note 6).

Changes in Presentation of Comparative Financial Statements—Certain reclassifications, such as the presentation of deferred tax assets and deferred tax liabilities (See Note 12), have been made to our prior period consolidated financial information in order to conform with the current year presentation. These changes did not have a significant impact on the consolidated financial statements.

Revenue Recognition—The Company recognizes revenue principally on four types of transactions: (i) monitoring, which includes revenues for monitoring of the Company’s subscriber contracts and certain subscriber contracts that have been sold, (ii) activation fees on the Company’s contracts, which are amortized over the expected life of the customer, (iii) service and other sales, which includes services provided on contracts, contract fulfillment revenue, sales of products that are not part of the basic equipment package and revenue from 2GIG, and (iv) contract sales.

Monitoring services 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. Revenue from monitoring contracts that have been sold is recognized monthly as services are provided based on rates negotiated as part of the contract sales. Costs of providing ongoing monitoring services are expensed in the period incurred.

Activation fees are generally charged to a customer when a new account is opened. This revenue is deferred and recognized using a 150% declining balance method over 12 years and converts to a straight-line methodology when the resulting revenue recognition is greater than that from the accelerated method for the remaining estimated life.

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.

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 in 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.

Revenue from the sale of subscriber contracts is recognized when ownership of the contracts has transferred to the purchaser. Any unamortized deferred revenue and costs related to contract sales are recognized at the time of the sale.

Subscriber Contract Costs—A portion of the direct costs of acquiring new subscribers, primarily sales commissions, equipment, and installation costs, are deferred and recognized over a pattern that reflects the estimated life of the subscriber relationships. For both the Successor Period and Predecessor Period, the Company amortizes these costs using a 150% declining balance method over 12 years and converts to a straight-line methodology when the resulting amortization charge is greater than that from the accelerated method for the remaining estimated life. The Company evaluates subscriber account attrition on a periodic basis, utilizing observed attrition rates for the Company’s subscriber contracts and industry information and, when necessary, makes adjustments to the estimated subscriber relationship period and amortization method.

In conjunction with the Merger and in accordance with purchase accounting, the total purchase price was allocated to the Company’s net tangible and identifiable intangible assets based on their estimated fair values as of November 16, 2012 (See Note 3). The Company recorded the value of Subscriber Contract Costs on the date of the Transactions at fair value and classified it as an intangible asset, which is amortized over 10 years in a pattern that is consistent with the amount of revenue expected to be generated from the related 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.

Restricted Cash and Cash Equivalents—Restricted cash and cash equivalents is restricted for a specific purpose and cannot be included in the general cash account. At December 31, 2013 and 2012, the restricted cash and cash equivalents was held by a third-party trustee. At December 31, 2013, the current portion of restricted cash and cash equivalents was $14,375,000. Restricted cash equivalents consists of highly liquid investments with remaining maturities when purchased of three months or less.

Accounts Receivable—Accounts receivable consists primarily of amounts due from customers for recurring monthly monitoring services. The accounts receivable are recorded at invoiced amounts and are non-interest bearing. The gross amount of accounts receivable has been reduced by an allowance for doubtful accounts of $1,901,000 and $2,301,000 at December 31, 2013 and 2012, respectively. The Company estimates this allowance based on historical collection rates, subscriber attrition rates, and contractual obligations underlying the sale of the subscriber contracts to third parties. When the Company determines that there are accounts receivable that are uncollectible, they are charged off against the allowance for doubtful accounts. As of December 31, 2013 and 2012, no accounts receivable were classified as held for sale. Provision for doubtful accounts is included in general and administrative expenses in the accompanying consolidated statements of operations.

The changes in the Company’s allowance for accounts receivable were as follows for the years ended (in thousands):

Inventories—Inventories, which comprise home automation and security system equipment and parts, are stated at the lower of cost or market with cost determined under the first-in, first-out (FIFO) method. The Company records an allowance for excess and obsolete inventory based on anticipated obsolescence, usage and historical write-offs. The allowance for excess and obsolete inventory was $3,167,000 and $1,484,000, as of December 31, 2013 and 2012, respectively.

Long-lived Assets and Intangibles—Property 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, 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. Amortization expense associated with leased assets is included with depreciation expense. Routine repairs and maintenance are charged to expense as incurred. 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. The Company periodically assesses potential impairment of its long-lived assets and intangibles and performs an impairment review whenever events or changes in circumstances indicate that the carrying value may not be recoverable. The Company has no intangible assets with indefinite useful lives.

Deferred Financing Costs—Costs incurred in connection with obtaining debt financing are deferred and amortized utilizing the straight-line method, which approximates the effective-interest method, over the life of the related financing. If such financing is paid off or replaced prior to maturity with debt instruments that have substantially different terms, the unamortized costs are charged to expense. In connection with refinancing the debt, in conjunction with the Transactions the Company wrote off $3,451,000 related to unamortized deferred financing costs associated with the Credit Agreement. Deferred financing costs included in the accompanying consolidated balance sheets at December 31, 2013 and 2012 were $59,375,000 and $57,322,000, net of accumulated amortization of $9,875,000 and $1,032,000, respectively. Amortization expense on deferred financing costs recognized and included in interest expense in the accompanying consolidated statements of operations, totaled $8,843,000 for the year ended December 31, 2013, $1,032,000 for the Successor Period ended December 31, 2012, $6,619,000 for the Predecessor Period ended November 16, 2012 and $7,709,000 for the year ended December 31, 2011.

Residual Income Plan—Prior to the Merger, the Company had a program that allowed sales representatives to elect to defer commission payments and for third-party sales channel partners to receive additional compensation based on the performance of the underlying contracts they created during the season. The Company calculated the present value of the expected future payments and recognized this amount in the period the commissions were earned. Subsequent accretion and adjustments to the estimated liability were recorded as interest and other expense, respectively. The Company monitored actual payments and customer attrition on a periodic basis and, when necessary, made adjustments to the liability. In connection with the Merger, the Company settled its obligation to the employee participants of this plan. The obligation related to commissions owed to third-party channel partners was not settled in connection with the Merger, and this program continued after the Merger. The amount included in accrued expenses and other current liabilities was $2,426,000 and $1,418,000 at December 31, 2013 and 2012, respectively, representing the present value of the estimated amounts owed to third-party sales channel partners.

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 13).

Advertising Expense—Advertising costs are expensed as incurred. Advertising costs were approximately $23,038,000 for the year ended December 31, 2013, $1,686,000 for the Successor Period ended December 31, 2012, $8,204,000 for the Predecessor Period ended November 16, 2012 and $8,505,000 for the year ended December 31, 2011.

Income Taxes—The Company accounts for income taxes based on the asset and liability method. Under the asset and liability method, deferred tax assets and deferred tax liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Valuation allowances are established when necessary to reduce deferred tax assets when it is determined that it is more likely than not that some portion of the deferred tax asset will not be realized.

The Company recognizes the effect of an uncertain income tax position on the income tax return at the largest amount that is more-likely-than-not to be sustained upon audit by the relevant taxing authority. An uncertain income tax position will not be recognized if it has less than a 50% likelihood of being sustained. The Company’s policy for recording interest and penalties is to record such items as a component of the provision for income taxes.

Liability—Contracts Sold—During 2007 and 2008, the Company received approximately $118,136,000 in proceeds from the sale of certain subscriber contracts to a third-party. Concurrently, the Company entered into an agreement with the buyer to continue providing monitoring and support services for the contracts that were sold. Following the initial one-year warranty period from the date of the sales, the Company had no obligation under the terms of the sales agreement to make any additional payments to the seller. In August 2012, the Company agreed to repurchase the contracts upon a change of control, as defined. As a result of this continuing involvement on the part of the Company in the servicing of the contracts, accounting guidance precluded gain recognition at the time of the sales. Accordingly, the Company recorded a liability for the proceeds received at the time of the sales and amortized the liability using the effective interest method over twelve years, the expected life of the subscriber contracts. The Company recorded the monthly fees from these contracts as monitoring revenue in the statements of operations. In connection with the Merger, these contracts were re-acquired and, as a result, the related liability was satisfied.

Use of Estimates—The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements. Actual results could differ from those estimates.

Concentrations of Credit Risk—Financial instruments that potentially subject the Company to concentration of credit risk consist principally of receivables and cash. At times during the year, the Company maintains cash balances in excess of insured limits. The Company is not dependent on any single customer or geographic location. The loss of a customer would not adversely impact the Company’s operating results or financial position.

Concentrations of Supply Risk—As of December 31, 2013, approximately 87% of the Company’s installed panels were 2GIG Go!Control panels. On April 1, 2013, the Company completed the 2GIG Sale. In connection with the 2GIG Sale, the Company entered into a five-year supply agreement with 2GIG, pursuant to which they will be the exclusive provider of the Company’s control panel requirements, subject to certain exceptions as provided in the supply agreement. The loss of 2GIG as a supplier could potentially impact the Company’s operating results or financial position.

Fair Value Measurement—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 fiscal 2013 or 2012.

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 and as necessary if changes in facts and circumstances indicate that the fair value of the Company’s reporting units may be less than its carrying amount. When indicators of impairment do not exist and certain accounting criteria are met, the Company is able to evaluate goodwill impairment using a qualitative approach. When necessary, the Company’s quantitative goodwill impairment test consists of two steps. The first step requires that the Company compare the estimated fair value of its reporting units to the carrying value of the reporting unit’s net assets, including goodwill. If the fair value of the reporting unit is greater than the carrying value of its net assets, goodwill is not considered to be impaired and no further testing is required. If the fair value of the reporting unit is less than the carrying value of its net assets, the Company would be required to complete the second step of the test by analyzing the fair value of its goodwill. If the carrying value of the goodwill exceeds its fair value, an impairment charge is recorded (See Note 10).

Foreign Currency Translation and Other Comprehensive Income—The functional currencies of Vivint Canada, Inc. and Vivint New Zealand, Ltd. are the Canadian dollar and the New Zealand dollar, respectively. Accordingly, assets and liabilities are translated from their respective functional currencies into U.S. dollars at year-end rates and revenue and expenses are translated at the weighted-average exchange rates for the year. Adjustments resulting from this translation process are classified as other comprehensive income (loss) and shown as a separate component of equity.

Letters of Credit—At December 31, 2013 and 2012, respectively, the Company had $2,174,000 and $2,168,000 of unused letters of credit associated with workers compensation and a bond line for the Company’s corporate, sales and installation personnel.

New Accounting Pronouncement—In September 2011, the FASB issued authoritative guidance which amends the process of testing goodwill for impairment. The guidance permits an entity to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not (defined as having a likelihood of more than fifty percent) that the fair value of a reporting unit is less than its carrying amount. If an entity determines it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, performing the traditional two-step goodwill impairment test is unnecessary. If an entity concludes otherwise, it would be required to perform the first step of the two-step goodwill impairment test. If the carrying amount of the reporting unit exceeds its fair value, then the entity is required to perform the second step of the goodwill impairment test. However, an entity has the option to bypass the qualitative assessment in any period and proceed directly to step one of the impairment test. The guidance became effective for the Company in the fourth quarter of fiscal year 2013. The adoption of this guidance did not have a material impact on the Company’s financial position, results of operations or cash flows.

In July 2012, the FASB issued authoritative guidance which amends the process of testing indefinite-lived intangible assets for impairment. This guidance permits an entity to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not (defined as having a likelihood of more than fifty percent) that the indefinite-lived intangible asset is impaired. If an entity determines it is not more likely than not that the indefinite-lived intangible asset is impaired, the entity will have an option not to calculate the fair value of an indefinite-lived asset annually. The guidance became effective for the Company in the fourth quarter of fiscal year 2013. The adoption of this guidance did not have a material impact on the Company’s financial position, results of operations or cash flows.

In February 2013, the FASB issued authoritative guidance which expands the disclosure requirements for amounts reclassified out of accumulated other comprehensive income (“AOCI”). The guidance requires an entity to provide information about the amounts reclassified out of AOCI by component and present, either on the face of the income statement or in the notes to financial statements, significant amounts reclassified out of AOCI by the respective line items of net income but only if the amount reclassified is required under GAAP to be reclassified to net income in its entirety in the same reporting period. For other amounts, an entity is required to cross-reference to other disclosures required under GAAP that provide additional detail about those amounts. This guidance does not change the current requirements for reporting net income or OCI in financial statements. The guidance is effective for the Company in the first quarter of fiscal year 2014. The adoption of this guidance is not expected to have a material impact on the Company’s financial position, results of operations or cash flows.

In July 2013, the FASB issued authoritative guidance which amends the guidance related to the presentation of unrecognized tax benefits and allows for the reduction of a deferred tax asset for a net operating loss carryforward whenever the net operating loss carryforward or tax credit carryforward would be available to reduce the additional taxable income or tax due if the tax position is disallowed. This guidance is effective for annual and interim periods for fiscal years beginning after December 15, 2013, and early adoption is permitted. The adoption of this guidance is not expected to have a material impact on the Company’s financial position, results of operations or cash flows.

Business Combinations [Abstract]
Business Combination	NOTE 2—BUSINESS COMBINATIONS				NOTE 3—BUSINESS COMBINATION
	Space Monkey Acquisition				As described in Note 1, the Merger was completed on November 16, 2012, and was financed by a combination of equity invested by affiliates of The Blackstone Group, certain co-investors, the Company’s management and certain employees and borrowings under senior credit facilities. The Company’s management and certain employees invested approximately $155,160,000 in the form of a rollover of their equity in APX and 2GIG and cash investments were used to repay all outstanding borrowings under the Predecessor’s secured credit facilities, pay Predecessor shareholders, purchase equity units of Acquisition LLC and pay transaction fees and expenses. As part of the Merger, as of December 31, 2013 and 2012, there was $28,428,000 held in escrow and presented as restricted cash in the accompanying financial statements for payments to employees that will be due in the next two years. At the time of the Transactions, approximately $54,300,000 was placed in escrow to cover potential adjustments to the total purchase consideration associated with general representations and warranties and adjustments to tangible net worth, in accordance with the terms of the Merger’s escrow agreement. This amount is included in the total purchase consideration discussed below. The remaining escrow balance, after all adjustments are made in accordance with the escrow agreement, are expected to be paid to the former Company shareholders no later than the second quarter of 2014. Because these amounts held in escrow are not controlled by the Company, they are not included in the accompanying consolidated balance sheets.
	On September 10, 2014, a wholly-owned subsidiary of the Company merged with Space Monkey, Inc. (“Space Monkey”), a data cloud storage technology company. Pursuant to the terms of the merger the Company paid aggregate cash consideration of $15.0 million, of which $1.5 million is held in escrow for indemnification obligations and is required to be released no later than December 31, 2014. This strategic acquisition was made to support the growth and development of the Company’s smart home platform. The accompanying condensed consolidated financial statements include the financial position and results of operations associated with the Space Monkey assets acquired and liabilities assumed from September 10, 2014. The pro forma impact of Space Monkey on the Company’s financial position and results of operations for the nine months ended September 30, 2014 is immaterial.				Purchase Consideration
	The determination of the final purchase price is subject to potential adjustments, primarily related to the valuation of certain intangible assets and income taxes. The following table summarizes the preliminary estimated fair value of the assets acquired and liabilities assumed at the time of acquisition (in thousands):				The following table summarizes the purchase price consideration (in thousands):

	During the nine months ended September 30, 2014, the Company incurred costs associated with the Space Monkey acquisition, which were not material, consisting of accounting, legal and professional fees and payments to employees directly associated with the acquisition. These costs are included in general and administrative expenses in the accompanying unaudited condensed consolidated statements of operations.
	Wildfire Acquisition				Purchase Price Allocation
	On January 31, 2014, a wholly-owned subsidiary of the Company completed the purchase of certain assets, and assumed certain liabilities, of Wildfire Broadband, LLC (“Wildfire”). Pursuant to the terms of the asset purchase agreement the Company paid aggregate cash consideration of $3.5 million, of which $0.4 million is held in escrow for indemnification obligations and is required to be released no later than January 31, 2015. This strategic acquisition was made to provide the Company access to Wildfire’s existing customers, wireless internet infrastructure and know-how. The accompanying condensed consolidated financial statements include the financial position and results of operations associated with the Wildfire assets acquired and liabilities assumed from January 31, 2014. The pro forma impact of Wildfire on the Company’s financial position and results of operations for the nine months ended September 30, 2014 is immaterial. The associated goodwill is deductible for income tax purposes.				The purchase price of approximately $1,935,638,000 includes the purchase of all outstanding stock, settlement of the Predecessor’s debt, settlement of stock-based awards, payments to employees under long-term incentive arrangements, transaction fees and expenses and purchase of subscriber accounts held by third parties. Payments to employees consisted of payments to officers, employees and directors as change in control payments and special retention bonuses. On the date of the Transactions, the Company paid $28,428,000 or 50% of the amount due to employees under long-term incentive arrangements. The remaining 50% will be paid in two equal payments on the second and third anniversary dates of the Merger. In addition to the payments under these long-term incentive arrangements, the Company also incurred $48,586,000 of costs related to bonus and other payments to employees directly related to the Transactions. These employee expenses are included in total costs and expenses in the Predecessor Period Consolidated Statement of Operations.
	The following table summarizes the estimated fair value of the assets acquired and liabilities assumed at the time of acquisition (in thousands):				The estimated fair values of the assets acquired and liabilities assumed are based on information obtained from various sources including, the Company’s management and historical experience. The fair value of the intangible assets was determined using the income and the cost approaches. Key assumptions used in the determination of fair value include projected cash flows, subscriber attrition rates and discount rates between 8% and 14%.

					Total purchase price allocation	$	1,935,638
	In addition, during the nine months ended September 30, 2014, the Company made a cost-based investment in a privately-held company (the “Investee”). The amount of the investment by the Company in the Investee was $0.3 million as of September 30, 2014. The Company could make up to $2.7 million in additional investments in the Investee, subject to the achievement of certain technology development milestones. These additional investments are expected to occur through July 1, 2016.
					Goodwill resulting from the Transactions is not deductible for income tax purposes.
					Transaction Related Costs
					The Company incurred costs associated with the Transactions of approximately $31,885,000 in the Successor Period from November 17, 2012 through December 31, 2012 and approximately $23,461,000 in the Predecessor Period from January 1, 2012 through November 16, 2012. These costs consist of accounting, investment banking, legal and professional fees and employee expenses directly associated with the Transactions and are included in the accompanying consolidated statements of operations.
					Smartrove Acquisition

	Revolving Credit Facility
	On November 16, 2012, APX, the Company 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.							Revolving Credit Facility
	Borrowings under the revolving credit facility bear interest at a rate per annum equal to an applicable margin plus, at our 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’s consolidated first lien net leverage ratio at the end of each fiscal quarter, commencing with delivery of its consolidated financial statements for the first full fiscal quarter ending after the closing date.							In connection with the Merger, APX, the Company and the other guarantors entered into a revolving credit facility in the aggregate principal amount of $200,000,000. Borrowings bear interest based on the London Interbank Offered Rate (“LIBOR”) or, at the Company’s option, an alternative base rate, plus spread, based upon the Company’s consolidated first lien leverage ratio at the end of each fiscal quarter and a commitment fee of 0.50% on unused portions of the revolving credit facility. The borrowings are due November 16, 2017, which may be repaid at any time without penalty.
	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 our consolidated first lien net leverage ratio) 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. The borrowings are due November 16, 2017, which may be repaid at any time without penalty.

Discontinued Operations	NOTE 6—DISCONTINUED OPERATIONS
	During the first quarter of 2012, the Company abandoned Smart Grid, a component of its energy management business. The circumstances leading up to the abandonment included a shift in the strategic direction for Smart Grid within the energy management framework. All operating activity ceased during the second quarter of 2012. No income taxes were recorded on discontinued operations because the tax effect was immaterial and the tax benefit of the loss was offset by a valuation allowance.

	Accounting rules require the primary beneficiary of a variable interest entity (“VIE”) to include the financial position and results of operations of the VIE in its condensed consolidated financial statements. Vivint Solar, Inc. (“Solar”), formed by the Company in April 2011, installs solar panels on the roofs of customers’ homes and enters into agreements for customers to purchase the electricity generated by the panels. Solar also takes advantage of local government and federal incentive programs that offer assistance in generating green power. Solar was consolidated as a VIE by APX Group, Inc. from April 2011 through November 15, 2012. On November 16, 2012, an investor group comprised of certain investment funds affiliated with Blackstone Capital Partners VI L.P., and certain co-investors and management investors (collectively, the “Investors”) purchased Solar for $75.0 million and became its primary beneficiary and, as a result, the Solar financial position and results of operations are not consolidated by the Company subsequent to November 16, 2012. The assets of Solar are restricted in that they are only available to settle the obligations of Solar and not of the Company and similarly, the creditors of Solar have no recourse to the general assets of the Company.	Accounting rules require the primary beneficiary of a variable interest entity (“VIE”) to include the financial position and results of operations of the VIE in its condensed consolidated financial statements. The Predecessor consolidated financial statements include APX Group, Inc. and its subsidiaries, and 2GIG and Solar, which were VIE’s prior to the Merger in the Predecessor Period. In connection with the Merger, 2GIG became a wholly-owned subsidiary and their financial position and results of operations were consolidated by the Company in the Successor Period through the date of the 2GIG Sale. Also in connection with the Merger, the Investors purchased Solar for $75,000,000 and, while Solar remains a VIE of the Company, the Investors became the primary beneficiary and, as a result, the Solar financial position and results of operations are not consolidated by the Company in the Successor Period.
	The Company and Solar have entered into an agreement under which the Company subleases corporate office space, and provides certain other administrative services, to Solar. During the nine months ended September 30, 2014 and 2013, the Company charged $5.9 million and $0.8 million, respectively, of general and administrative expenses to Solar in connection with this agreement. The balance due from Solar in connection with this agreement and other expenses paid on Solar’s behalf was $3.1 million at December 31, 2013 and is included in prepaid expenses and other current assets in the accompanying unaudited condensed consolidated balance sheets. The balance due from Solar in connection with this agreement at September 30, 2014 was immaterial.	2GIG
		2GIG is engaged in the manufacture, wholesale distribution, and monitoring of electronic home security and automation systems primarily in the United States and Canada. 2GIG supplies the majority of the equipment used by the Company in its security systems installations. Sales of this equipment to other legal entities owned or consolidated by the Company represented approximately 71% of 2GIG’s total sales during 2013 through April 1, 2013, the date of the 2GIG Sale. The Company determined that 2GIG was a VIE, prior to the Merger, and the Company was the primary beneficiary because Vivint, Inc. was 2GIG’s largest customer, 2GIG was dependent on Vivint, Inc. for ongoing financial support and because the Company, through its related parties, had the ability to control the operations of 2GIG. Accordingly, as indicated above, the financial position and results of operations are consolidated by the Company for the Predecessor Period. Non-controlling interests in the consolidated financial statements include the portion of equity and results of operations related to 2GIG.
	On December 27, 2012, the Company executed a Subordinated Note and Loan Agreement with Solar. The terms of the agreement state that Solar may borrow up to $20.0 million, bearing interest on the outstanding balance at an annual rate of 7.5%, which interest is due and payable semi-annually on June 1 and December 1 of each year commencing on June 1, 2013. The balance outstanding on September 30, 2014, representing principal of $20.0 million and payment-in-kind interest of $2.2 million, and on December 31, 2013, representing principal of $20.0 million and payment-in-kind interest of $1.3 million, is included in prepaid and other current assets and long-term investments and other assets, net, respectively, in the accompanying unaudited condensed consolidated balance sheets. In addition, accrued interest of $0.5 million and $0.1 million on September 30, 2014 and December 31, 2013, respectively, is included in prepaid expenses and other current assets in the accompanying unaudited condensed consolidated balance sheets. These variable interests represent the Company’s maximum exposure to loss from direct involvement with Solar.	Solar
		Solar, formed in April 2011, installs solar panels on the roofs of customer’s homes and enters into purchase agreements for the customers to purchase the electricity generated by the panels. Solar also takes advantage of local government and federal incentive programs that offer assistance in generating green power. During the Predecessor Period, the Company determined that Solar was a VIE and the Company was the primary beneficiary because Solar was dependent on Vivint, Inc. for ongoing financial support and because the Company had the ability to control the operations of Solar through its related parties. Accordingly, as indicated above, the financial position and results of operations are consolidated by the Company for the Predecessor Period and not for the Successor Period. The assets of Solar are restricted in that they are only available to settle the obligations of Solar and not of the Company and similarly, the creditors of Solar have no recourse to the general assets of the Company.
		On June 1, 2011, Vivint, Inc. and Solar entered into an Administrative Services Agreement (“Service Agreement”) and a Trademark License Agreement (“Trademark Agreement”). The Service Agreement provided Solar with certain administrative, managerial and account management services to be performed by Vivint. In exchange for the services and licenses under these agreements, Solar agreed to pay Vivint a combined fee of $0.05 per kilowatt hour of electricity generated by the solar equipment each month for each customer account. In June 2013, the Company and Solar entered into a Turnkey Full-Service Sublease Agreement (“Sublease Agreement”) and terminated the Service Agreement. The Sublease Agreement specifies the terms under which the Company subleases corporate office space, and provides certain other administrative services, to Solar. The Trademark Agreement was also amended in conjunction with the execution of the Sublease Agreement. During the year ended December 31, 2013, the Company charged $2,883,000 of general and administrative expenses to Solar in connection with the Sublease Agreement. As of December 31, 2013, the balance of $3,070,000 due from Solar in connection with the Sublease Agreement and other expenses paid on Solar’s behalf is included in prepaid expenses and other current assets in the accompanying consolidated balance sheets.
		In June 2011, the Company entered into a Revolving Credit Note (“Loan”) with Solar. This Loan was due in May 2013, had a principal balance of $5,000,000 and accrued interest at a rate per annum equal to 13%. In connection with the Merger, the loan was satisfied and there was no balance outstanding as of December 31, 2013 or 2012.
		On December 27, 2012, the Company executed a new Subordinated Note and Loan Agreement with Solar. The terms of the agreement state that Solar may borrow up to $20,000,000, bearing interest on the outstanding balance at an annual rate of 7.5% based on a 365 day year, which interest is due and payable semi-annually on June 1 and December 1 of each year commencing on June 1, 2013. The balance outstanding on December 31, 2013, representing principal of $20,000,000 and payment-in-kind interest of $1,323,000, is included in long-term investments and other assets in the accompanying consolidated balance sheets. In addition, accrued interest of $138,000 is included in prepaid expenses and other current assets in the accompanying consolidated balance sheets. The balance outstanding on December 31, 2012 was $15,000,000. These variable interests represent the Company’s maximum exposure to loss from direct involvement with Solar.

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	NOTE 9—FAIR VALUE MEASUREMENTS									NOTE 11—FAIR VALUE MEASUREMENTS
	Cash equivalents and restricted cash equivalents are classified as Level 1 as they have readily available market prices in an active market. The preferred stock, as defined below, is classified as Level 3 and is valued using its cost basis, which approximates fair value. The following summarizes the financial instruments of the Company at fair value based on the valuation approach applied to each class of security as of September 30, 2014 and December 31, 2013 (in thousands):									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. In order to increase consistency and comparability in fair value measurements, accounting guidance establishes a fair value hierarchy that prioritizes observable and unobservable inputs used to measure fair value into three broad levels. These levels, in order of highest priority to lowest priority, are described below:
										Level 1: Quoted prices (unadjusted) in active markets that are accessible at the measurement date for assets or liabilities.
										Level 2: Observable prices that are based on inputs not quoted on active markets, but corroborated by market data.
		Fair Value Measurement at Reporting Date Using								Level 3: Unobservable inputs are used when little or no market data is available.

										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.
	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.									The fair market value of the Company’s Senior Secured Notes was approximately $941,188,000 as of December 31, 2013 and $917,980,000 as of December 31, 2012. The carrying value of the Company’s Senior Secured Notes was $925,000,000 as of December 31, 2013 and December 31, 2012. The Company’s Senior Notes had a fair market value of approximately $844,525,000 as of December 31, 2013 and $374,478,000 as of December 31, 2012 and a carrying amount of $830,000,000 as of December 31, 2013 and $380,000,000 as of December 31, 2012. The fair value of the Senior Secured Notes and the Senior Notes was considered a Level 2 measurement as the value was determined using observable market inputs, such as current interest rates as well as prices observable from less active markets.
	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 preferred stock has been classified as available-for-sale and measured at fair value in accordance with ASC 320, Investments—Debt and Equity Securities, with remeasurement occurring at the end of each reporting period and any changes in fair value included in other comprehensive income. As of September 30, 2014, the estimated aggregate fair value of the preferred stock was equal to its cost of $3.0 million and was considered a Level 3 measurement and is included in long-term investments and other assets, net in the accompanying unaudited condensed consolidated balance sheet as of September 30, 2014. There were no gains or losses recognized for the nine months ended September 30, 2014 associated with this investment.									In connection with the Transactions, the fair value of intangible assets was considered a Level 3 measurement and was determined using the income and cost approach and input obtained from various sources, including the Company’s management and historical experience. Key assumptions used in the determination of fair value include projected cash flows, subscriber attrition rates and discount rates between 8% and 14%.
	The fair market value of the Company’s Senior Secured Notes was approximately $898.4 million and $941.2 million as of September 30, 2014 and December 31, 2013, respectively. The carrying value of the Company’s Senior Secured Notes was $925.0 million as of September 30, 2014 and December 31, 2013. The Company’s Senior Notes had a fair market value of approximately $846.3 million and $844.5 million as of September 30, 2014 and December 31, 2013, respectively, and a carrying amount of $930.0 million and $830.0 million as of September 30, 2014 and December 31, 2013, respectively. The fair value of the Senior Secured Notes and the Senior Notes was considered a Level 2 measurement as the value was determined using observable market inputs, such as current interest rates as well as prices observable from less active markets.									In connection with the Smartrove acquisition, the fair value of intangible assets was considered a Level 3 measurement and was determined using the cost and relief from royalty approach. Key assumptions used in the determination of the fair value include estimated replacement costs, hypothetical royalty rates and a discount rate of 25%.
	In connection with the Wildfire acquisition, the fair value of intangible assets was considered a Level 3 measurement and was determined using the income and market approach. Key assumptions used in the determination of the fair value include estimated earnings and discount rates between 12% and 20%.
	In connection with the Space Monkey acquisition, the fair value of intangible assets was considered a Level 3 measurement and was determined using the income approach. Key assumptions used in the determination of the fair value include an internal rate of return and a weighted average cost of capital of 25% and 20%, respectively.

INCOME_TAXES

INCOME TAXES	9 Months Ended	12 Months Ended
	Sep. 30, 2014	Dec. 31, 2013
Income Tax Disclosure [Abstract]
INCOME TAXES	NOTE 11—INCOME TAXES	NOTE 12—INCOME TAXES
	In order to determine the quarterly provision (benefit) 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.	APX Group files a consolidated federal income tax return with its wholly-owned subsidiaries.
	The Company’s effective income tax rate for the nine months ended September 30, 2014 was approximately 0.19%. In computing income tax expense (benefit), 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, 2014, 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. Both the 2014 and 2013 effective tax rates are less than the statutory rate due to the combination of not recognizing benefit for expected pre-tax losses of the US jurisdiction, recognizing current state income tax expense for minimum state taxes and the reduction of the valuation allowance as a result of the Space Monkey acquisition.	For tax purposes, the Transaction was treated as a stock acquisition. As a result, assets and liabilities were not adjusted to fair value for tax purposes. Goodwill resulting from the transaction is not deductible for tax purposes. For tax purposes, acquisition costs are divided into three categories; deductible costs, amortizable costs, and capitalized costs. Acquisition costs are allocated among the categories based on the nature and timing of the incurred cost. Deductible costs are deducted in the period incurred. Amortizable costs are capitalized and amortized over a period of 15 years. Capitalized costs are capitalized to the cost of the stock and are not amortized.
	For 2014, 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 September 30, 2014, 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.

		United States (“U.S.”) and state net operating loss carryforwards will begin to expire in 2026, if not used. Canadian net operating loss carryforwards will begin to expire in 2029. Included in both the U.S. and state net operating loss carryforwards was approximately $11,483,000 at both December 31, 2013 and 2012 of net operating loss carryforwards for which a benefit will be recorded in Additional Paid in Capital when realized. The Company had no U.S. alternative minimum tax credits at December 31, 2013, and U.S. alternative minimum tax credits of $71,000 at December 31, 2012, for which life is unlimited. The Company had no U.S. research and development credits at December 31, 2013, and U.S. research and development credits of approximately $30,000 at December 31, 2012, which begin to expire in 2030. Realization of the Company’s net operating loss carryforwards and tax credits is dependent on generating sufficient taxable income prior to their expiration. The Company has determined that there is an IRC Section 382 limitation with respect to the carryforward items.
		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 $48,685,000 at December 31, 2013. The Company had no valuation allowance for U.S. deferred tax assets at December 31, 2012. 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, 2013, the Company’s income tax returns for the years ended December 31, 2007 through December 31, 2013, remain subject to examination by the Internal Revenue Service and state authorities.

	313 Incentive Units					Stock-Based Compensation
	The Company’s indirect parent, 313 Acquisition LLC (“313”), which is wholly owned by the Investors, has authorized the award of profits interests, representing the right to share a portion of the value appreciation on the initial capital contributions to 313 (“Incentive Units”). As of September 30, 2014, a total of 75,181,252 Incentive Units had been awarded to current and former members of senior management and a board member, of which 46,484,562 were issued 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 anticipates making comparable equity incentive grants at 313 to other members of senior management and adopting other equity and cash-based incentive programs for other members of management from time to time. 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 55% to 65%; expected exercise term from 4 to 5 years; and risk-free rate of 0.62% to 1.18%.					Successor
	Vivint Stock Appreciation Rights					313 Incentive Units
	The Company’s subsidiary, Vivint, has awarded Stock Appreciation Rights (“SARs”) to various levels of key employees. The purpose of the SARs is to attract and retain personnel and provide an opportunity to acquire an equity interest of Vivint. 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 Blackstone. In connection with this plan, 7,296,250 SARs were outstanding as of September 30, 2014. In addition, 36,065,303 SARs have been set aside for funding incentive compensation pools pursuant to long-term incentive plans established by the Company.					As of December 31, 2013, 313 Acquisition LLC had authorized a total of 74,062,836 profits interests, representing the right to share a portion of the value appreciation on the initial capital contributions to 313 Acquisition LLC (“Incentive Units”). As of December 31, 2013, a total of 69,659,562 Incentive Units had been awarded to members of senior management and a board member, of which 46,484,562 were issued to the Company’s Chief Executive Officer and President in conjunction with the Transactions. 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. The Company anticipates making comparable equity incentive grants at 313 Acquisition LLC to other members of senior management and adopting other equity and cash-based incentive programs for other members of management from time to time. 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 60% to 65%; expected exercise term from 4.3 to 5 years; and risk-free rate of 0.62% to 1.18%.

	Indemnification—Subject to certain limitations, the Company is obligated to indemnify its current and former directors, officers and employees with respect to certain litigation matters and investigations that arise in connection with their service to the Company. These obligations arise under the terms of its certificate of incorporation, its bylaws, applicable contracts, and Delaware and California law.

The obligation to indemnify generally means that the Company is required to pay or reimburse the individuals’ reasonable legal expenses and possibly damages and other liabilities incurred in connection with these matters.
	Legal—The Company is named from time to time as a party to lawsuits arising in the ordinary course of business related to its sales, marketing, the provision of its services and equipment claims. Actions filed against the Company include commercial, intellectual property, customer, and labor and employment related claims, including complaints of alleged wrongful termination and potential class action lawsuits regarding alleged violations of federal and state wage and hour and other laws. In general, litigation can be expensive and disruptive to normal business operations. Moreover, the results of legal proceedings are difficult to predict, and the costs incurred in litigation can be substantial. The Company believes the amounts provided in its financial statements are adequate in light of the probable and estimated liabilities. Factors that the Company considers in the determination of the likelihood of a loss and the estimate of the range of that loss in respect of legal matters include the merits of a particular matter, the nature of the matter, the length of time the matter has been pending, the procedural posture of the matter, how the Company intends to defend the matter, the likelihood of settling the matter and the anticipated range of a possible settlement. Because such matters are subject to many uncertainties, the ultimate outcomes are not predictable and there can be no assurances that the actual amounts required to satisfy alleged liabilities from the matters described above will not exceed the amounts reflected in the Company’s financial statements or that the matters will not have a material adverse effect on the Company’s results of operations, financial condition or cash flows.

	Prior to the 2GIG Sale on April 1, 2013, the Company conducted business through two operating segments, Vivint and 2GIG.

The primary source of revenue for the 2GIG segment was through the sale of electronic security and automation systems to security dealers and distributors, including Vivint. Fees and expenses charged by 2GIG to Vivint, related to intercompany purchases, were eliminated in consolidation.

Accounting Policies [Abstract]
BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES	NOTE 1—BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES
	Unaudited Interim Financial Statements
	The accompanying interim unaudited condensed consolidated financial statements included in this Quarterly Report on Form 10-Q have been prepared by APX Group Holdings, Inc. and subsidiaries (the “Company” or “APX”) without audit. Certain information and footnote disclosures normally included in consolidated financial statements prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) have been condensed or omitted pursuant to such rules and regulations. The information as of December 31, 2013 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 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 nine months ended September 30, 2014 are not necessarily indicative of the results that may be expected for the year ending December 31, 2014.
	These unaudited condensed consolidated financial statements and notes should be read in conjunction with the Company’s audited consolidated financial statements and related notes for the years ended December 31, 2013 and 2012 set forth in the Company’s Annual Report on Form 10-K dated March 24, 2014, as filed with the Securities and Exchange Commission (“SEC”), which is available on the SEC’s website at sec.gov.
	The direct-to-home component of the sales cycle for the Company is seasonal in nature. The summer sales season generally runs from late April to the end of August each year. The Company makes investments in the recruitment of the sales force and inventory prior to the summer sales season. The Company experiences increases in subscriber acquisition costs, as well as costs to support the sales force around North America, during the summer sales season.
	Basis of Presentation—The unaudited condensed consolidated financial statements of the Company are presented for APX Group Holdings, Inc. and its wholly-owned subsidiaries. On April 1, 2013, the Company completed the sale of 2GIG Technologies, Inc. (“2GIG”) and its subsidiary to Nortek, Inc. (the “2GIG Sale”). Therefore, its results of operations are excluded following the sale and the results of operations prior to and subsequent to the 2GIG Sale are not necessarily comparable.
	Revenue Recognition—The Company recognizes revenue principally on three types of transactions: (i) monitoring, which includes revenues for monitoring and other automation services of the Company’s subscriber contracts and certain subscriber contracts that have been sold, (ii) service and other sales, which includes services provided on contracts, contract fulfillment revenue, sales of products that are not part of the basic equipment package and revenue from 2GIG, and (iii) activation fees on the Company’s contracts, which are amortized over the expected life of the customer.
	Monitoring services 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. Revenue from monitoring contracts that have been sold is recognized monthly as services are provided based on rates negotiated as part of the contract sales. Costs of providing ongoing monitoring 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 are generally charged to a customer when a new account is opened. This revenue is deferred and recognized using a 150% declining balance method over 12 years and converts to a straight-line methodology when the resulting revenue recognition is greater than that from the accelerated method for the remaining estimated life.
	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.
	Revenue from the sale of subscriber contracts is recognized when ownership of the contracts has transferred to the purchaser. Any unamortized deferred revenue and costs related to contract sales are recognized at the time of the sale.
	Subscriber Contract Costs—A portion of the direct costs of acquiring new subscribers, primarily sales commissions, equipment, and installation costs, are deferred and recognized over a pattern that reflects the estimated life of the subscriber relationships. The Company amortizes these costs over the estimated useful life by using a 150% declining balance method over 12 years and converts to a straight-line methodology when the resulting amortization charge is greater than that from the accelerated method for the remaining estimated life. The Company evaluates subscriber account attrition on a periodic basis, utilizing observed attrition rates for the Company’s subscriber contracts and industry information and, when necessary, makes adjustments to the estimated subscriber relationship period and amortization method.
	Cash and Cash Equivalents—Cash and cash equivalents consists of highly liquid investments with remaining maturities when purchased of three months or less.
	Restricted Cash and Cash Equivalents—Restricted cash and cash equivalents is restricted for a specific purpose and cannot be included in the general cash account. At September 30, 2014 and December 31, 2013, the restricted cash and cash equivalents was held by a third-party trustee. Restricted cash and cash equivalents consists of highly liquid investments with remaining maturities when purchased of three months or less.
	Accounts Receivable—Accounts receivable consists primarily of amounts due from customers for recurring monthly monitoring services. The accounts receivable are recorded at invoiced amounts and are non-interest bearing. The gross amount of accounts receivable has been reduced by an allowance for doubtful accounts of $3.3 million and $1.9 million at September 30, 2014 and December 31, 2013, respectively. The Company estimates this allowance based on historical collection rates, subscriber attrition rates, and contractual obligations underlying the sale of the subscriber contracts to third parties. When the Company determines that there are accounts receivable that are uncollectible, they are charged off against the allowance for doubtful accounts. As of September 30, 2014 and December 31, 2013, no accounts receivable were classified as held for sale. Provision for doubtful accounts is included in general and administrative expenses in the accompanying unaudited condensed consolidated statements of operations.
	The changes in the Company’s allowance for accounts receivable were as follows for the periods ended (in thousands):
		Nine Months Ended
		September 30,
		2014			2013
	Beginning balance	$	1,901		$	2,301
	Provision for doubtful accounts		11,275			8,299
	Write-offs and adjustments		(9,894	)		(8,040	)
	Balance at end of period	$	3,282		$	2,560
	Inventories—Inventories, which comprise home automation and security system equipment and parts, are stated at the lower of cost or market with cost determined under the first-in, first-out (FIFO) method. The Company records an allowance for excess and obsolete inventory based on anticipated obsolescence, usage and historical write-offs.
	Long-lived Assets and Intangibles—Property 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, 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. Amortization expense associated with leased assets is included with depreciation expense. Routine repairs and maintenance are charged to expense as incurred. 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. The Company periodically assesses potential impairment of its long-lived assets and intangibles and performs an impairment review whenever events or changes in circumstances indicate that the carrying value may not be recoverable. In addition, the Company periodically assesses whether events or changes in circumstance continue to support an indefinite life of certain intangible assets or warrant a revision to the estimated useful life of definite-lived intangible assets.
	Deferred Financing Costs—Costs incurred in connection with obtaining debt financing are deferred and amortized utilizing the straight-line method, which approximates the effective-interest method, over the life of the related financing. If such financing is paid off or replaced prior to maturity with debt instruments that have substantially different terms, the unamortized costs are charged to expense. Deferred financing costs included in the accompanying unaudited condensed consolidated balance sheets at September 30, 2014 and December 31, 2013 were $54.6 million and $59.4 million, net of accumulated amortization of $17.4 million and $9.9 million, respectively. Amortization expense on deferred financing costs recognized and included in interest expense in the accompanying unaudited condensed consolidated statements of operations, totaled $7.6 million and $6.5 million for the nine months ended September 30, 2014 and 2013, respectively.
	Residual Income Plan—The Company has a program that allows third-party sales channel partners to receive additional compensation based on the performance of the underlying contracts they create. The Company calculates the present value of the expected future payments and recognizes this amount in the period the commissions are earned. Subsequent accretion and adjustments to the estimated liability are recorded as interest and other expense, respectively. The Company monitors actual payments and customer attrition on a periodic basis and, when necessary, makes adjustments to the liability. The amount included in accrued expenses and other current liabilities was $0.4 million and $0.3 million as of September 30, 2014 and December 31, 2013, respectively, and the amount included in other long-term obligations was $2.7 million and $2.4 million at September 30, 2014 and December 31, 2013, respectively, representing the present value of the estimated amounts owed to third-party sales channel partners.
	Stock-Based Compensation—The Company measures compensation cost based on the grant-date fair value of the award and recognizes that cost over the requisite service period of the awards (See Note 12).
	Income Taxes—The Company accounts for income taxes based on the asset and liability method. Under the asset and liability method, deferred tax assets and deferred tax liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Valuation allowances are established when necessary to reduce deferred tax assets when it is determined that it is more likely than not that some portion of the deferred tax asset will not be realized.
	The Company recognizes the effect of an uncertain income tax position on the income tax return at the largest amount that is more-likely-than-not to be sustained upon audit by the relevant taxing authority. An uncertain income tax position will not be recognized if it has less than a 50% likelihood of being sustained. The Company’s policy for recording interest and penalties is to record such items as a component of the provision for income taxes.
	Liability—Contracts Sold—On March 31, 2014, the Company received approximately $2.3 million in proceeds from the sale of certain subscriber contracts to a third-party. Concurrently, the Company entered into an agreement with the buyer to continue providing billing, monitoring and support services for the contracts that were sold for a period of ten years. As a result of this continuing involvement on the part of the Company in the servicing of the contracts, accounting guidance precluded gain recognition at the time of the sale. Accordingly, the Company has treated this transaction as a secured borrowing and recorded a liability for the proceeds received at the time of the sale. The amount included in accrued expenses and other current liabilities related to this liability was $2.1 million as of September 30, 2014. These amounts are being amortized using the effective interest method over twelve years, the expected term of these subscriber contracts.
	Use of Estimates—The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements. Actual results could differ from those estimates.
	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, 2014, approximately 75% of the Company’s installed panels were 2GIG Go!Control panels and 17% were SkyControl panels. On April 1, 2013, the Company completed the 2GIG Sale. In connection with the 2GIG Sale, the Company entered into a five-year supply agreement with 2GIG, pursuant to which they will be the exclusive provider of the Company’s control panel requirements, subject to certain exceptions as provided in the supply agreement. The loss of 2GIG as a supplier could potentially impact the Company’s operating results or financial position.
	Fair Value Measurement—Fair value is based on the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Assets and liabilities subject to on-going fair value measurement are categorized and disclosed into one of three categories depending on observable or unobservable inputs employed in the measurement. These two types of inputs have created the following fair value hierarchy:
	Level 1: Quoted prices in active markets that are accessible at the measurement date for assets and liabilities.
	Level 2: Observable prices that are based on inputs not quoted in active markets, but corroborated by market data.
	Level 3: Unobservable inputs are used when little or no market data is available.
	This hierarchy requires the Company to minimize the use of unobservable inputs and to use observable market data, if available, when determining fair value. The Company recognizes transfers between levels of the hierarchy based on the fair values of the respective financial measurements at the end of the reporting period in which the transfer occurred. There were no transfers between levels of the fair value hierarchy during the nine months ended September 30, 2014 and the fiscal year 2013.
	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 and as necessary if changes in facts and circumstances indicate that the fair value of the Company’s reporting units may be less than its carrying amount. When indicators of impairment do not exist and certain accounting criteria are met, the Company is able to evaluate goodwill impairment using a qualitative approach. When necessary, the Company’s quantitative goodwill impairment test consists of two steps. The first step requires that the Company compare the estimated fair value of its reporting units to the carrying value of the reporting unit’s net assets, including goodwill. If the fair value of the reporting unit is greater than the carrying value of its net assets, goodwill is not considered to be impaired and no further testing is required. If the fair value of the reporting unit is less than the carrying value of its net assets, the Company would be required to complete the second step of the test by analyzing the fair value of its goodwill. If the carrying value of the goodwill exceeds its fair value, an impairment charge is recorded.
	Foreign Currency Translation and Other Comprehensive Income—The functional currencies of Vivint Canada, Inc. and Vivint New Zealand, Ltd. are the Canadian and New Zealand dollars, respectively. Accordingly, assets and liabilities are translated from their respective functional currencies into U.S. dollars at period-end rates and revenue and expenses are translated at the weighted-average exchange rates for the period. Adjustments resulting from this translation process are classified as other comprehensive income (loss) and shown as a separate component of equity.
	Letters of Credit—As of September 30, 2014 and December 31, 2013, the Company had $3.0 million and $2.2 million, respectively, of letters of credit issued in the ordinary course of business, all of which are undrawn.
	New Accounting Pronouncement—In May 2014, the FASB 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, 2016. 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 our consolidated financial statements.
	In February 2013, the FASB issued authoritative guidance which expands the disclosure requirements for amounts reclassified out of accumulated other comprehensive income (“AOCI”). The guidance requires an entity to provide information about the amounts reclassified out of AOCI by component and present, either on the face of the income statement or in the notes to financial statements, significant amounts reclassified out of AOCI by the respective line items of net income but only if the amount reclassified is required under GAAP to be reclassified to net income in its entirety in the same reporting period. For other amounts, an entity is required to cross-reference to other disclosures required under GAAP that provide additional detail about those amounts. This guidance does not change the current requirements for reporting net income or OCI in financial statements. The guidance became effective for us in the first quarter of fiscal year 2014. The adoption of this guidance did not have a material impact on our financial position, results of operations or cash flows.
	In July 2013, the FASB issued authoritative guidance which amends the guidance related to the presentation of unrecognized tax benefits and allows for the reduction of a deferred tax asset for a net operating loss carryforward whenever the net operating loss carryforward or tax credit carryforward would be available to reduce the additional taxable income or tax due if the tax position is disallowed. This guidance became effective for us for annual and interim periods beginning in fiscal year 2014. The adoption of this guidance did not have a material impact on our financial position, results of operations or cash flows.

	Identifiable intangible assets acquired by the Company in connection with the Wildfire acquisition were $2.1 million of customer contracts and $0.8 million associated with non-compete agreements entered into by certain former members of Wildfire management. Identifiable intangible assets acquired by the Company in connection with the Space Monkey acquisition were $7.1 million of Space Monkey technology and $1.2 million associated with non-compete agreements entered into by certain former members of Space Monkey management. In addition, during the nine months ended September 30, 2014, the Company acquired $6.5 million of other intangible assets related to patents, domain names and Internet Protocol (“IP”) addresses.
	On March 29, 2014, the Company implemented new customer relationship management software (“CRM”). Historically, the Company’s customer management system (“CMS”) technology was used for customer support and inventory tracking. The new CRM software replaced the customer support functionality of the CMS technology. Following the CRM implementation, the CMS technology continued to be used for inventory tracking. Due to the implementation of the new CRM software, as of March 31, 2014, the Company determined there to be a significant change in the extent and manner in which the CMS technology was being used. The Company estimated the fair value of the CMS technology as of March 31, 2014 to be $0.3 million based on management experience, inquiry and assessment of the remaining functionality of this technology as it related to inventory tracking. The associated impairment loss of $1.4 million is included in operating expenses in the accompanying unaudited condensed consolidated statement of operations for the nine months ended September 30, 2014. In addition, the estimated remaining useful life of the CMS technology was evaluated and revised to one year from March 31, 2014, based on the intended use of the asset. The impact on income from continuing operations and net income from the change in the estimated remaining useful life was immaterial.
	Amortization expense related to intangible assets was approximately $113.3 million and $123.4 million for the nine months ended September 30, 2014 and 2013, respectively.

Changes in Presentation of Comparative Financial Statements

Changes in Presentation of Comparative Financial Statements—Certain reclassifications, such as the presentation of deferred tax assets and deferred tax liabilities (See Note 12), have been made to our prior period consolidated financial information in order to conform with the current year presentation. These changes did not have a significant impact on the consolidated financial statements.

Revenue Recognition

Revenue Recognition—The Company recognizes revenue principally on three types of transactions: (i) monitoring, which includes revenues for monitoring and other automation services of the Company’s subscriber contracts and certain subscriber contracts that have been sold, (ii) service and other sales, which includes services provided on contracts, contract fulfillment revenue, sales of products that are not part of the basic equipment package and revenue from 2GIG, and (iii) activation fees on the Company’s contracts, which are amortized over the expected life of the customer.

Revenue Recognition—The Company recognizes revenue principally on four types of transactions: (i) monitoring, which includes revenues for monitoring of the Company’s subscriber contracts and certain subscriber contracts that have been sold, (ii) activation fees on the Company’s contracts, which are amortized over the expected life of the customer, (iii) service and other sales, which includes services provided on contracts, contract fulfillment revenue, sales of products that are not part of the basic equipment package and revenue from 2GIG, and (iv) contract sales.

Monitoring services 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. Revenue from monitoring contracts that have been sold is recognized monthly as services are provided based on rates negotiated as part of the contract sales. Costs of providing ongoing monitoring 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.

Subscriber Contract Costs

Subscriber Contract Costs—A portion of the direct costs of acquiring new subscribers, primarily sales commissions, equipment, and installation costs, are deferred and recognized over a pattern that reflects the estimated life of the subscriber relationships. The Company amortizes these costs over the estimated useful life by using a 150% declining balance method over 12 years and converts to a straight-line methodology when the resulting amortization charge is greater than that from the accelerated method for the remaining estimated life. The Company evaluates subscriber account attrition on a periodic basis, utilizing observed attrition rates for the Company’s subscriber contracts and industry information and, when necessary, makes adjustments to the estimated subscriber relationship period and amortization method.

Long-lived Assets and Intangibles

Long-lived Assets and Intangibles—Property 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, 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. Amortization expense associated with leased assets is included with depreciation expense. Routine repairs and maintenance are charged to expense as incurred. 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. The Company periodically assesses potential impairment of its long-lived assets and intangibles and performs an impairment review whenever events or changes in circumstances indicate that the carrying value may not be recoverable. The Company has no intangible assets with indefinite useful lives.

Deferred Financing Costs

Deferred Financing Costs—Costs incurred in connection with obtaining debt financing are deferred and amortized utilizing the straight-line method, which approximates the effective-interest method, over the life of the related financing. If such financing is paid off or replaced prior to maturity with debt instruments that have substantially different terms, the unamortized costs are charged to expense. Deferred financing costs included in the accompanying unaudited condensed consolidated balance sheets at September 30, 2014 and December 31, 2013 were $54.6 million and $59.4 million, net of accumulated amortization of $17.4 million and $9.9 million, respectively. Amortization expense on deferred financing costs recognized and included in interest expense in the accompanying unaudited condensed consolidated statements of operations, totaled $7.6 million and $6.5 million for the nine months ended September 30, 2014 and 2013, respectively.

Residual Income Plan

Residual Income Plan—The Company has a program that allows third-party sales channel partners to receive additional compensation based on the performance of the underlying contracts they create. The Company calculates the present value of the expected future payments and recognizes this amount in the period the commissions are earned. Subsequent accretion and adjustments to the estimated liability are recorded as interest and other expense, respectively. The Company monitors actual payments and customer attrition on a periodic basis and, when necessary, makes adjustments to the liability. The amount included in accrued expenses and other current liabilities was $0.4 million and $0.3 million as of September 30, 2014 and December 31, 2013, respectively, and the amount included in other long-term obligations was $2.7 million and $2.4 million at September 30, 2014 and December 31, 2013, respectively, representing the present value of the estimated amounts owed to third-party sales channel partners.

Residual Income Plan—Prior to the Merger, the Company had a program that allowed sales representatives to elect to defer commission payments and for third-party sales channel partners to receive additional compensation based on the performance of the underlying contracts they created during the season.

Subsequent accretion and adjustments to the estimated liability were recorded as interest and other expense, respectively. The Company monitored actual payments and customer attrition on a periodic basis and, when necessary, made adjustments to the liability. In connection with the Merger, the Company settled its obligation to the employee participants of this plan. The obligation related to commissions owed to third-party channel partners was not settled in connection with the Merger, and this program continued after the Merger. The amount included in accrued expenses and other current liabilities was $2,426,000 and $1,418,000 at December 31, 2013 and 2012, respectively, representing the present value of the estimated amounts owed to third-party sales channel partners.

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.

Concurrently, the Company entered into an agreement with the buyer to continue providing billing, monitoring and support services for the contracts that were sold for a period of ten years. As a result of this continuing involvement on the part of the Company in the servicing of the contracts, accounting guidance precluded gain recognition at the time of the sale. Accordingly, the Company has treated this transaction as a secured borrowing and recorded a liability for the proceeds received at the time of the sale. The amount included in accrued expenses and other current liabilities related to this liability was $2.1 million as of September 30, 2014. These amounts are being amortized using the effective interest method over twelve years, the expected term of these subscriber contracts.

Liability—Contracts Sold—During 2007 and 2008, the Company received approximately $118,136,000 in proceeds from the sale of certain subscriber contracts to a third-party. Concurrently, the Company entered into an agreement with the buyer to continue providing monitoring and support services for the contracts that were sold. Following the initial one-year warranty period from the date of the sales, the Company had no obligation under the terms of the sales agreement to make any additional payments to the seller. In August 2012, the Company agreed to repurchase the contracts upon a change of control, as defined. As a result of this continuing involvement on the part of the Company in the servicing of the contracts, accounting guidance precluded gain recognition at the time of the sales. Accordingly, the Company recorded a liability for the proceeds received at the time of the sales and amortized the liability using the effective interest method over twelve years, the expected life of the subscriber contracts. The Company recorded the monthly fees from these contracts as monitoring revenue in the statements of operations. In connection with the Merger, these contracts were re-acquired and, as a result, the related liability was satisfied.

Use of Estimates

Use of Estimates—The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements. Actual results could differ from those estimates.

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, 2014, approximately 75% of the Company’s installed panels were 2GIG Go!Control panels and 17% were SkyControl panels. On April 1, 2013, the Company completed the 2GIG Sale. In connection with the 2GIG Sale, the Company entered into a five-year supply agreement with 2GIG, pursuant to which they will be the exclusive provider of the Company’s control panel requirements, subject to certain exceptions as provided in the supply agreement. The loss of 2GIG as a supplier could potentially impact the Company’s operating results or financial position.

Fair Value Measurement

Fair Value Measurement—Fair value is based on the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Assets and liabilities subject to on-going fair value measurement are categorized and disclosed into one of three categories depending on observable or unobservable inputs employed in the measurement. These two types of inputs have created the following fair value hierarchy:

Fair Value Measurement—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 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 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.

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, 2014 and the fiscal year 2013.

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 fiscal 2013 or 2012.

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 and as necessary if changes in facts and circumstances indicate that the fair value of the Company’s reporting units may be less than its carrying amount. When indicators of impairment do not exist and certain accounting criteria are met, the Company is able to evaluate goodwill impairment using a qualitative approach. When necessary, the Company’s quantitative goodwill impairment test consists of two steps. The first step requires that the Company compare the estimated fair value of its reporting units to the carrying value of the reporting unit’s net assets, including goodwill. If the fair value of the reporting unit is greater than the carrying value of its net assets, goodwill is not considered to be impaired and no further testing is required. If the fair value of the reporting unit is less than the carrying value of its net assets, the Company would be required to complete the second step of the test by analyzing the fair value of its goodwill. If the carrying value of the goodwill exceeds its fair value, an impairment charge is recorded.

Foreign Currency Translation and Other Comprehensive Income

Foreign Currency Translation and Other Comprehensive Income—The functional currencies of Vivint Canada, Inc. and Vivint New Zealand, Ltd. are the Canadian and New Zealand dollars, respectively. Accordingly, assets and liabilities are translated from their respective functional currencies into U.S. dollars at period-end rates and revenue and expenses are translated at the weighted-average exchange rates for the period. Adjustments resulting from this translation process are classified as other comprehensive income (loss) and shown as a separate component of equity.

Letters of Credit

Letters of Credit—As of September 30, 2014 and December 31, 2013, the Company had $3.0 million and $2.2 million, respectively, of letters of credit issued in the ordinary course of business, all of which are undrawn.

Letters of Credit—At December 31, 2013 and 2012, respectively, the Company had $2,174,000 and $2,168,000 of unused letters of credit associated with workers compensation and a bond line for the Company’s corporate, sales and installation personnel.

New Accounting Pronouncement

New Accounting Pronouncement—In May 2014, the FASB 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, 2016. 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 our consolidated financial statements.

New Accounting Pronouncement—In September 2011, the FASB issued authoritative guidance which amends the process of testing goodwill for impairment. The guidance permits an entity to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not (defined as having a likelihood of more than fifty percent) that the fair value of a reporting unit is less than its carrying amount. If an entity determines it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, performing the traditional two-step goodwill impairment test is unnecessary. If an entity concludes otherwise, it would be required to perform the first step of the two-step goodwill impairment test. If the carrying amount of the reporting unit exceeds its fair value, then the entity is required to perform the second step of the goodwill impairment test. However, an entity has the option to bypass the qualitative assessment in any period and proceed directly to step one of the impairment test. The guidance became effective for the Company in the fourth quarter of fiscal year 2013. The adoption of this guidance did not have a material impact on the Company’s financial position, results of operations or cash flows.

In February 2013, the FASB issued authoritative guidance which expands the disclosure requirements for amounts reclassified out of accumulated other comprehensive income (“AOCI”). The guidance requires an entity to provide information about the amounts reclassified out of AOCI by component and present, either on the face of the income statement or in the notes to financial statements, significant amounts reclassified out of AOCI by the respective line items of net income but only if the amount reclassified is required under GAAP to be reclassified to net income in its entirety in the same reporting period. For other amounts, an entity is required to cross-reference to other disclosures required under GAAP that provide additional detail about those amounts. This guidance does not change the current requirements for reporting net income or OCI in financial statements. The guidance became effective for us in the first quarter of fiscal year 2014. The adoption of this guidance did not have a material impact on our financial position, results of operations or cash flows.

In July 2012, the FASB issued authoritative guidance which amends the process of testing indefinite-lived intangible assets for impairment. This guidance permits an entity to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not (defined as having a likelihood of more than fifty percent) that the indefinite-lived intangible asset is impaired. If an entity determines it is not more likely than not that the indefinite-lived intangible asset is impaired, the entity will have an option not to calculate the fair value of an indefinite-lived asset annually. The guidance became effective for the Company in the fourth quarter of fiscal year 2013. The adoption of this guidance did not have a material impact on the Company’s financial position, results of operations or cash flows.

In July 2013, the FASB issued authoritative guidance which amends the guidance related to the presentation of unrecognized tax benefits and allows for the reduction of a deferred tax asset for a net operating loss carryforward whenever the net operating loss carryforward or tax credit carryforward would be available to reduce the additional taxable income or tax due if the tax position is disallowed. This guidance became effective for us for annual and interim periods beginning in fiscal year 2014. The adoption of this guidance did not have a material impact on our financial position, results of operations or cash flows.

Long-lived Assets and Intangibles

Long-lived Assets and Intangibles—Property 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, 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. Amortization expense associated with leased assets is included with depreciation expense. Routine repairs and maintenance are charged to expense as incurred. 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. The Company periodically assesses potential impairment of its long-lived assets and intangibles and performs an impairment review whenever events or changes in circumstances indicate that the carrying value may not be recoverable. In addition, the Company periodically assesses whether events or changes in circumstance continue to support an indefinite life of certain intangible assets or warrant a revision to the estimated useful life of definite-lived intangible assets.

						Vivint Stock Appreciation Rights
						During the year ended December 31, 2013, the Company’s subsidiary, Vivint, awarded Stock Appreciation Rights (“SARs”) to various levels of key employees. The purpose of the SARs is to attract and retain personnel and provide an opportunity to acquire an equity interest of Vivint. 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 The Blackstone Group, L.P. and its affiliates. In connection with this plan, 8,262,500 SARs have been granted as of December 31, 2013. In addition, 36,065,303 have been reserved for future issuance in accordance with a long-term incentive plan established by the Company. Vivint expects to continue regular quarterly grants to new employees who meet the award criteria.
						The fair value of the Vivint 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 60%, expected dividends of 0%; expected exercise term of 6.04 years; and risk-free rate of 1.72%. Due to the lack of historical exercise data, the Company used the simplified method in determining the estimated exercise term, for all Vivint awards. There was no SAR activity for the Successor Period from November 17, 2012 through December 31, 2012. A summary of the SAR activity for the year ended December 31, 2013 is presented below:
