Summary of Significant Accounting Policies | Summary of Significant Accounting Policies Principles of Consolidation Our consolidated financial statements include our accounts and those of our majority-owned and controlled subsidiaries after elimination of intercompany accounts and transactions. Equity investments over which we are able to exercise significant influence but do not control the investee are accounted for using the equity method. We determine whether we have a controlling financial interest in an entity by first evaluating whether the entity is a voting interest entity or a variable interest entity (“VIE”). Voting interest entities are entities that have sufficient equity and provide equity investor voting rights that give them power to make significant decisions relating to the entity’s operations. The usual condition for a controlling financial interest in a voting interest entity is ownership of a majority voting interest. In VIEs, a controlling financial interest is attained through means other than voting rights and the entities lack one or more of the characteristics of a voting entity. We account for our unconsolidated investments in businesses under the cost or equity method dependent on factors such as percent ownership and factors that would determine significant influence. Our cost method investments are recorded at cost. Equity method investments are recorded at cost and adjusted to record our share of the company’s undistributed gains and losses in our consolidated statements of operations. We evaluate our cost and equity method investments for impairment whenever events or circumstances indicate that carrying amount of such investments may not be recoverable. Use of Estimates The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Our estimates, judgments and assumptions are continually evaluated based on available information and experience. Because of the use of estimates inherent in the financial reporting process, actual results could differ from those estimates. Estimates are used when accounting for revenue recognition, allowances for doubtful accounts receivable, allowance for hardware returns, estimates of obsolete inventory, long-term incentive compensation, stock-based compensation, income taxes, legal reserves, contingent consideration and goodwill and intangible assets. Cash and Cash Equivalents We consider all highly liquid instruments purchased with an original maturity from the date of purchase of three months or less to be cash equivalents. As of December 31, 2015 and 2014, we have invested approximately $122.8 million and $38.6 million in cash equivalents in the form of money market funds with one financial institution. We consider these money market funds to be Level 1 financial instruments. Accounts Receivable Accounts receivable are principally derived from sales to customers located in the United States and Canada. Substantially all of our sales in Canada are transacted in U.S. dollars. During the years ended December 31, 2015, 2014 and 2013, less than 1% of our revenue was generated outside of North America and as of December 31, 2015 and 2014, 2% of accounts receivable balances were related to service providers outside of North America. Our accounts receivable are stated at estimated realizable value. We utilize the allowance method to provide for doubtful accounts based on management’s evaluation of the collectability of the amounts due. Our estimate is based on historical collection experience and a review of the current status of accounts receivable. Each of our service providers are evaluated for creditworthiness through a credit review process at the inception of the arrangement or if risk indicators arise during our arrangement at such other time. Our terms for hardware sales to our service providers and distributors typically allow for returns for up to one year. We apply our estimate as a percentage of sales monthly, based on historical data, as a reserve against revenue to account for our provision for returns. We have not experienced write-offs for uncollectible accounts or sales returns that have differed significantly from our estimates. Inventory Our inventory, which is comprised of raw materials and finished goods, includes materials used to produce our wireless communications network enabled radios, video cameras, home automation system parts and peripherals, is stated at the lower of cost or market, and is charged to cost of sales on a first in, first out (“FIFO”) basis. We periodically evaluate our inventory quantities for obsolescence based on criteria such as customer demand and changing technology and record an obsolescence write down when necessary. Marketable Securities In 2013 and 2014, we had investments in marketable equity securities consisting of available for sale securities, which were stated at fair value, with unrealized gains and temporary unrealized losses reported as a component of other comprehensive income, net of tax, until realized. When realized, we recognized gains and losses on the sales of the securities on a specific identification method and include the realized gains or losses in other (expense) / income, net in the consolidated statements of operations. We included interest, dividends, and amortization of premium or discount on securities classified as available for sale in other (expense) / income, net in the consolidated statements of operations. As of December 31, 2015 and 2014, there were no investments in marketable equity securities. Internal-Use Software We capitalize the costs related to the design of internal-use software related to the development of our platform during the application development stage of the projects. The costs are primarily comprised of salaries, benefits and stock-based compensation expense of the projects’ engineers and product development teams. Our internally developed software is reported at cost less accumulated depreciation. Depreciation begins once the project is ready for its intended use, which is usually when the code goes into production in weekly software builds on our platform. We depreciate the asset on a straight-line basis over a period of three years, which is the estimated useful life. We utilize continuous agile development methods to update our software for our SaaS multi-tenant platform on a weekly basis, which primarily consists of bug-fixes and user interface changes. We evaluate whether a project should be capitalized if it adds significant functionality to our platform. Maintenance activities or minor upgrades are expensed in the period performed. Revenue Recognition and Deferred Revenue We derive our revenue from two primary sources: the sale of software-as-a-service ("SaaS") cloud-based connected home platform and the sale of hardware products that enable our solutions. We sell our hardware and platform solutions to service providers that resell our hardware and solutions to home and business owners, who are the service providers’ customers, and whom we refer to as our subscribers. We also sell our hardware to distributors who resell the hardware to service providers. We enter into contracts with our service providers that establish pricing for access to our connected home platform solutions and for the sale of hardware. These contracts typically have an initial term of one year, with subsequent renewal terms of one year. Our service providers typically enter into underlying contracts with our subscribers, which our service providers have indicated range from three to five years in length. Our hardware includes cellular radio modules that enable access to our cloud-based platform, as well as video cameras, image sensors and other peripherals. Our service providers purchase our hardware in anticipation of installing the hardware in a home or business when they create a new subscriber account, or for use in an existing subscriber’s property. The purchase of hardware occurs in a transaction that is separate and typically in advance of the purchase of our platform services. Service providers transact with us to purchase our platform solutions and resell our solutions to a new subscriber, or to upgrade or downgrade the solutions of an existing subscriber, at which time the subscriber’s access to our platform solutions is enabled and the delivery of the services commences. The purchase of hardware and the purchase of our platform solutions are separate transactions as, at the point of sale of the hardware, the service provider is not obligated to purchase a platform solution for the hardware sold, and the level and duration of platform solutions, if any, to be provided through the hardware sold cannot be determined. We recognize revenue with respect to our solutions when all of the following conditions are met: • Persuasive evidence of an arrangement exists; • Delivery to the customer, which may be either a service provider, distributor or a subscriber, has occurred or service has been rendered; • Fees are fixed or determinable; and • Collection of the fees is reasonably assured. We consider a signed contract with a service provider to be persuasive evidence that an agreement exists, and the fees to be fixed or determinable if the fees are contractually agreed to with our service providers. Collectability is evaluated based on a number of factors, including a credit review of new service providers, and the payment history of existing service providers. If collectability is not reasonably assured, revenue is deferred until collection becomes reasonably assured, which is generally upon the receipt of payment. SaaS and License Revenue We generate the majority of our SaaS and license revenue primarily from monthly fees charged to our service providers sold on a per subscriber basis for access to our cloud-based connected home platform and the related solutions. Our fees per subscriber vary based upon the service plan and features utilized. Under negotiated terms in our contractual arrangements with our service providers, we are entitled to, and recognize revenue based on a monthly fee that is billed in advance of the month of service. We have demonstrated that we can sell our SaaS offering on a stand-alone basis, as it can be sold separately from hardware and activation services. As there is no minimum required initial service term nor is there a stated renewal term in our contractual arrangements, we recognize revenue over the period of service, which is monthly. Our service providers typically incur and pay the same monthly fee per subscriber account for the entire period a subscriber account is active. We offer multiple service level packages for our solutions including a range of solutions and a range of a la carte add-ons for additional features. The fee paid by our service providers each month for the delivery of our solutions is based on the combination of packages and add-ons enabled for each subscriber. We utilize tiered pricing plans where our service providers may receive prospective pricing discounts driven by volume. We also generate SaaS and license revenue from the fees paid to us when we license our intellectual property to service providers on a per customer basis for use of our patents. In addition, in some markets our EnergyHub subsidiary sells its demand response software with an annual service fee, with pricing based on the number of subscribers or amount of aggregate electricity demand made available for a utility’s or market’s control. Hardware and Other Revenue We generate hardware and other revenue primarily from the sale of cellular radio modules that provide access to our cloud-based platform and, to a lesser extent, the sale of other devices, including video cameras, image sensors and peripherals. We recognize hardware and other revenue when the hardware is received by our service provider or distributor, net of a reserve for estimated returns. Amounts due from the sale of hardware are payable in accordance with the terms of our agreements with our service providers or distributors, and are not contingent on resale to end-users, or to service providers in the case of sales of hardware to distributors. Our terms for hardware sales sold directly to either service providers or distributors typically allow for the return of hardware up to one year past the date of sale. Our distributors sell directly to our service providers under terms between the two parties. We record a percentage of hardware and other revenue of approximately 2 to 4% , based on historical returns, as a reserve against revenue for hardware returns. We evaluate our hardware reserve on a quarterly basis or if there is an indication of significant changes in return experience. Historically, our returns of hardware have not significantly differed from our estimated reserve. Hardware and other revenue also includes activation fees charged to service providers for activation of a new subscriber account on our platform, as well as fees paid by service providers for our marketing services. Our service providers use services on our platform to assist in the installation of our solutions in a subscriber’s property. This installation marks the beginning of the service period on our platform and on occasion, we earn activation revenue for fees charged for this service. The activation fee is non-refundable, separately negotiated and specified in our contractual arrangements with our service providers and is charged to the service provider for each subscriber activated on our platform. Activation fees are not offered on a stand-alone basis separate from our SaaS offering and are billed and received at the beginning of the arrangement. We record activation fees initially as deferred revenue and we recognize these fees ratably over the expected term of the subscribers’ account which we estimate is ten years based on our annual attrition rate. The portion of these activation fees included in current and long-term deferred revenue as of our balance sheet date represents the amounts that will be recognized ratably as revenue over the following twelve months, or longer as appropriate, until the ten -year expected term is complete. The combined current and long-term balance for deferred revenue for activation fees was $11.0 million and $10.3 million as of December 31, 2015 and 2014. Cost of Revenue Our cost of SaaS and license revenue primarily includes the amounts paid to wireless network providers and, to a lesser extent, the costs of running our network operation centers which are expensed as incurred. Our cost of hardware and other revenue primarily includes cost of raw materials and amounts paid to our third-party manufacturer for production and fulfillment of our cellular radio modules and image sensors, and procurement costs for our video cameras, which we purchase from an original equipment manufacturer, and other devices. We carry our inventory at lower cost or market and the cost is charged to cost of sales on a FIFO basis when the inventory is shipped from our manufacturer and received by our service providers. Our cost of revenue excludes amortization and depreciation. Fair Value Measurements The accounting standard for fair value measurements provides a framework for measuring fair value and requires disclosures regarding fair value measurements. Fair value is defined as the price that would be received for an asset or the exit price that would be paid to transfer a liability in the principal or most advantageous market in an orderly transaction between market participants on the measurement date. This accounting standard established a fair value hierarchy, which requires an entity to maximize the use of observable inputs, where available. The following summarizes the three levels of inputs: Level 1 - Quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity can access at the measurement date; Level 2 - Inputs other than quoted prices included within Level 1 that are observable for similar assets and liabilities, either directly or indirectly; quoted prices in markets that are not active; and Level 3 - Unobservable inputs supported by little or no market activity. The carrying amount of financial assets, including cash and cash equivalents, accounts receivable and accounts payable approximates fair value because of the short maturity and liquidity of those instruments. Assets and Liabilities Measured at Fair Value on a Recurring Basis - In 2013 and 2014, we had an available for sale investment and derivatives that were recorded at fair value on a recurring basis. In 2015, we recorded at fair value on a recurring basis a liability for two subsidiary awards and a contingent consideration liability related to an acquisition. Assets Measured at Fair Value on a Nonrecurring Basis - We measure certain assets, including property and equipment, goodwill, intangible assets, cost and equity method investments at fair value on a nonrecurring basis. These assets are recognized at fair value when they are deemed to be other-than-temporarily impaired. Concentration of Credit Risk The financial instruments that potentially subject us to concentrations of credit risk consists principally of cash and cash equivalents and accounts receivables. All of our cash and cash equivalents are held at financial institutions that management believes to be of high credit quality. Our cash and cash equivalent accounts may exceed federally issued limits at times. We have not experienced any losses on cash and cash equivalents to date. To manage accounts receivable risk, we evaluate the credit worthiness of our service providers and maintain an allowance for doubtful accounts. The majority of our accounts receivable balance is made up of our service providers in North America. We assess the concentrations of credit risk with respect to accounts receivables based on one industry and geographic region and feel that our reserve for uncollectible accounts is appropriate based on our history and this concentration. Stock-Based Compensation We compensate our executive officers, board of directors and our employees with incentive stock-based compensation plans. In June 2015, our board of directors adopted, our stockholders approved, and we registered the shares for our 2015 Equity Incentive Plan (the "2015 Plan"), pursuant to which we reserved and registered 4,700,000 shares of common stock for issuance to our employees, directors and non-employee directors and consultants. The registration included 141,222 shares of our common stock previously reserved for issuance under our Amended and Restated 2009 Stock Incentive Plan (the "2009 Plan") that were added to the shares reserved under the 2015 Plan upon its effectiveness. We record stock-based compensation expense based upon the award’s grant date fair value and use an accelerated attribution method, net of estimated forfeitures, in which compensation cost for each vesting tranche in an award is recognized ratably from the service inception date to the vesting date for that tranche. Our equity awards generally vest over five years and are settled in shares of our common stock. During 2015, 2014 and 2013, we recognized compensation expense of $4.1 million , $3.3 million and $0.8 million , and associated income tax benefit of $0.7 million , $0.8 million and $0.2 million , respectively, in connection with our stock-based compensation plans. We account for stock-based compensation arrangements with non-employees using a fair value approach. The fair value of these options is measured using the Black-Scholes option pricing model reflecting the same assumptions as applied to employee options in each of the reported periods, other than the expected life, which is assumed to be the remaining contractual life of the option. The compensation costs of these arrangements are subject to remeasurement over the vesting terms, as earned. Employee Stock Purchase Plan We adopted our Employee Stock Purchase Plan (the "2015 ESPP") in June 2015. Under the 2015 ESPP, 1,200,000 shares have been initially reserved for future grant with provisions established to increase the number of shares available on January 1 of each subsequent year for nine years. The annual automatic increase in the number of shares available for issuance under the 2015 ESPP is the lesser of 1% of each class of common stock outstanding as of December 31 of the preceding fiscal year, 1,500,000 shares of common stock or such lesser number as determined by the board of directors. The 2015 ESPP allows eligible employees to purchase shares of our common stock at 90% of the fair market value, rounded up to the nearest cent, based on the closing price of our common stock on the purchase date. The maximum number of shares of our common stock that a participant may purchase during any calendar year shall not exceed such number of shares having a fair market value equal to the lesser of $15,000 or 10% of the participant's base compensation for that year. The 2015 ESPP is considered compensatory for purposes of share-based compensation expense due to the 10% discount on the fair market value of the common stock. In 2015 , there were no purchases of shares as our first offering period under the plan ended on February 15, 2016. We recognized less than $0.1 million of compensation expense in 2015. Compensation expense is recognized for the amount of the discount, net of forfeitures, over the six-month purchase period, based on the monthly closing price of our common stock as an estimate of the final purchase price for the period. This estimate is adjusted monthly until the purchase is finalized. As of December 31, 2015 , 1,200,000 shares remain available for future issuance. Business Combinations The purchase price of an acquisition is allocated to the assets acquired, including intangible assets, and liabilities assumed, based on their respective fair values at the acquisition date. Acquisition-related costs are expensed as incurred. The excess of the cost of an acquired entity over the net of the amounts assigned to the assets acquired and liabilities assumed is recognized as goodwill. The net assets and results of operations of an acquired entity are included in our consolidated financial statements from the acquisition date. Impairment of Long-Lived Assets We evaluate the recoverability of our long-lived assets for impairment whenever events or circumstances indicate that the carrying amount of the assets may not be recoverable. Recoverability of long-lived assets are measured by comparison of the carrying amount of the asset to the future undiscounted cash flows the asset is expected to generate. If the asset is considered to be impaired, the amount of any impairment is measured as the difference between the carrying value and the fair value of the impaired asset. Goodwill and Intangible Assets Goodwill represents the excess of (1) the aggregate of the fair value of consideration transferred in a business combination, over (2) the fair value of assets acquired, net of liabilities assumed. Goodwill is allocated to our reporting units, which are our operating segments or one level below our operating segments. Goodwill is not amortized, but is subject to annual impairment tests. We perform our annual impairment review of goodwill on October 1 and when a triggering event occurs between annual impairment tests. We test our goodwill at the reporting unit level. We review goodwill for impairment using the two-step process if, based on our assessment of the qualitative factors, we determine that it is more likely than not that the fair value of a reporting unit is less than its carrying value. For our 2015 annual impairment review, we performed a qualitative assessment for our Alarm.com reporting unit, our only reporting unit with a goodwill balance. This reporting unit had a fair value that exceeded its carrying value by more than 100% in the last quantitative assessment performed in 2014. We perform a quantitative analysis every three years. We first assessed qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. Qualitative factors we consider include, but are not limited to, macroeconomic conditions, industry and market conditions, company specific events, changes in circumstances and market capitalization. For the year ended December 31, 2015, we assessed the qualitative factors and determined that it was more likely than not that the fair value of the reporting unit exceeded the carrying value and that the two-step impairment test was not required. If a two-step impairment test is required, the fair value of the reporting unit is compared with its carrying value (including goodwill). If the fair value of the reporting unit is less than its carrying value, an indication of goodwill impairment exists for the reporting unit and step two is required to measure the amount of the impairment, if any. Under step two, an impairment loss is recognized for any excess of the carrying amount of the reporting unit’s goodwill over the implied fair value of that goodwill. The implied fair value of goodwill is determined by allocating the fair value of the reporting unit in a manner similar to a purchase price allocation and the residual fair value after this allocation is the implied fair value of the reporting unit goodwill. If the carrying value of goodwill exceeds the implied fair value, an impairment charge would be recorded to operating expenses in the period the determination is made. If the fair value of the reporting unit exceeds its carrying value, step two does not need to be performed. Intangible assets are initially valued at fair value using generally accepted valuation methods appropriate for the type of intangible asset. Intangible assets with definite lives are amortized over their estimated useful lives and are reviewed for impairment if indicators of impairment arise. The fair value of the intangible assets is compared with their carrying value and an impairment loss would be recognized for the amount by which the carrying amount exceeds the fair value. For the year ended December 31, 2015, we determined there were no indicators of impairment of our definite-lived intangible assets. Advertising Costs We expense advertising costs as incurred. Advertising costs totaled $3.7 million, $5.9 million and $8.2 million for the years ended December 31, 2015, 2014 and 2013. Advertising costs are included within sales and marketing expenses on our consolidated statements of operations. Accounting for Income Taxes We account for income taxes under the asset and liability method as required by accounting standards codification, or ASC 740, “Income Taxes,” which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that are included in the financial statements. Under this method, deferred tax assets and liabilities are determined based on the differences between the financial statements and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date. We record net deferred tax assets to the extent we believe these assets will more likely than not be realized. In making such a determination, we consider all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies, and results of recent operations. We are subject to income taxes in the United States. Significant judgment is required in evaluating uncertain tax positions. We record uncertain tax positions in accordance with ASC 740-10 on the basis of a two-step process whereby (1) we determine whether it is more likely than not that the tax positions will be sustained based on the technical merits of the position, and (2) with respect to those tax positions that meet the more-likely-than-not recognition threshold, we recognize the largest amount of tax benefit that is greater than 50% likely to be realized upon ultimate settlement with the related tax authority. We record interest and penalties as a component of our income tax provision. Earnings per Share (“EPS”) Our basic net (loss) / income per share attributable to common stockholders is calculated by dividing the net income attributable to common stockholders by the weighted-average number of shares of common stock outstanding for the period. Our diluted net (loss) / income per share attributable to common stockholders is calculated by giving effect to all potentially dilutive common stock when determining the weighted-average number of common shares outstanding. For purposes of the diluted net (loss) / income per share calculation, options to purchase common stock, redeemable convertible preferred stock, and unvested shares issued upon the early exercise of options that are subject to repurchase are considered to be potential common stock. We have issued securities other than common stock that participate in dividends (“participating securities”), and therefore utilize the two-class method to calculate net (loss) / income per share. These participating securities include redeemable convertible preferred stock and unvested shares issued upon the early exercise of options that are subject to repurchase, both of which have non-forfeitable rights to participate in any dividends declared on our common stock. The two-class method requires a portion of net income to be allocated to the participating securities to determine the net (loss) / income attributable to common stockholders. Net (loss) / income attributable to the common stockholders is equal to the net income less dividends paid on preferred stock and unvested shares with any remaining earnings allocated in accordance with the bylaws between the outstanding common and preferred stock as of the end of each period. Recent Accounting Pronouncements Adopted On November 20, 2015, the FASB issued ASU 2015-17, “Income Taxes (Topic 740) Balance Sheet Classification of Deferred Taxes," which simplifies the presentation of deferred income taxes and requires entities to classify deferred income tax liabilities and assets as noncurrent on the balance sheet. Prior to this accounting standard update, Topic 740, Income Taxes, required an entity to separate deferred income tax liabilities and assets for each jurisdiction into current and noncurrent amounts on the balance sheets. The amendments in this update may be applied either prospectively to all deferred tax liabilities and assets or retrospectively to all periods presented. The amendment is effective for annual periods, including periods within those annual periods beginning after December 15, 2016 with early adoption permitted. In the fourth quarter of 2015, we early adopted and retrospectively applied this update for all periods presented. To retrospectively adopt this pronouncement, we reclassified the previously reported $3.2 million current portion of deferred tax assets to long-term deferred tax assets on our balance sheet as of December 31, 2014. On August 18, 2015, the FASB issued ASU 2015-15, “Interest- Imputation of Interest (Subtopic 835-30): Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements - Amendments to SEC Paragraphs Pursuant to Staff Announcement at June 18, 2015, EITF Meeting,” which clarifies the application of ASU 2015-03 related to presentation and subsequent measurement of debt issuance costs related to line-of-credit arrangements to allow for an entity to defer and present debt issuance costs as an asset and subsequently amortize the deferred debt issuance costs ratably over the line-of-credit arrangement, regardless of whether there are any outstanding borrowings. ASU 2015-03, “ Simplifying the Presentation of Debt Issuance Costs,” otherwise requires debt issuance costs to be presented in the balance sheet as a direct deduction from the carrying value of the associated debt liability, consistent with the presentation of a debt discount. We adopted these pronouncements in the third quarter of 2015. The ad |
