Summary of Significant Accounting Policies | 2. Summary of Significant Accounting Policies Basis of Presentation The accompanying consolidated financial statements have been prepared in conformity with generally accepted accounting principles (“GAAP”) accepted in the United States of America and include the accounts of the Company and its wholly owned subsidiaries after elimination of all intercompany accounts and transactions. All dollar amounts in the financial statements and in the notes to the consolidated financial statements, except share and per share amounts, are stated in thousands of U.S. dollars unless otherwise indicated. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements, the disclosure of contingencies at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Significant estimates and assumptions reflected in these financial statements include, but are not limited to, the estimated average customer relationship period that is used for recognizing the deferred revenue of up-front fees and for amortizing the related deferred costs of in-vehicle devices, the valuation of accounts receivable reserves and share-based awards, the assessment of amounts qualifying for capitalization as internal-use software, the valuation of assets and liabilities acquired in business combinations, the useful lives of intangible assets and property and equipment, and the accounting for income taxes, including uncertain tax positions and the valuation of net deferred tax assets. Estimates are periodically reviewed in light of changes in circumstances, facts and experience. Actual results could differ materially from the Company’s estimates. Fair Value Measurements Certain assets and liabilities are carried at fair value under GAAP. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. A fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the last is considered unobservable, is used to measure fair value: • Level 1—Quoted prices in active markets for identical assets or liabilities. The Company did not have any financial assets and liabilities as of December 31, 2015 designated as Level 1. • Level 2—Observable inputs (other than Level 1 quoted prices) such as quoted prices in active markets for similar assets or liabilities, quoted prices in markets that are not active for identical or similar assets or liabilities, or other inputs that are observable or can be corroborated by observable market data. The Company did not have any financial assets and liabilities as of December 31, 2015 designated as Level 2. • Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to determining the fair value of the assets or liabilities, including pricing models, discounted cash flow methodologies and similar techniques. The Company has a contingent consideration liability assumed as a result of the Ornicar acquisition of $2,460 as of December 31, 2015 designated as Level 3. The Company’s contingent purchase consideration is valued by probability weighting expected payment scenarios and then applying a discount based on the present value of the future cash flow streams. This liability is classified as Level 3 because the probability weighting of future payment scenarios is based on assumptions developed by management. The Company determined a probability weighting that is weighted towards Ornicar achieving certain unit sales and pricing targets at the time of acquisition and the discount rate that is based on the Company’s weighted average cost of capital which is then adjusted for the time value of money. The probability weighting will be adjusted as the actual results provide the Company with more reliable information to weight the probability scenarios. In the fourth quarter of 2015, the contingent consideration liability increased by $0.3 million, as the estimated liability was revised based on expected results compared to actual performance criteria. The $0.3 million of contingent consideration expense is included in our general and administrative expense for the year ended December 31, 2015. The carrying values of accounts receivable, accounts payable and accrued expenses and other liabilities (with the exception of the Level 3 fair value measurement noted above) approximate fair value due to the short-term nature of these assets and liabilities. As of December 31, 2015 and 2014, the Company had no other assets or liabilities that would be classified under this fair value hierarchy. The fair value of the Company’s long-term debt related to the Credit Facility approximates its carrying value due to its variable interest rate, which approximates a market interest rate. Restricted Cash As of December 31, 2015, $135 is classified as restricted cash in the consolidated balance sheet. This restricted cash relates to a deposit in accordance with one of our operating leases. The Company is a party to various credit card and merchant services agreements under which it had pledged a continuing security interest in related deposit accounts in order to secure payment and performance of its obligations under the agreements. These restrictions may be lifted by the Company at will by canceling the agreements or reducing the lines of credit under these agreements. As of December 31, 2013, $64 had been classified as restricted cash in the consolidated balance sheet related to these arrangements. In 2014, the Company discontinued the use of certain company issued credit cards, which eliminated the requirement of the $64 restricted cash balance. Accounts Receivable and Allowance for Doubtful Accounts Accounts receivable are carried at their original invoice amounts less an allowance for doubtful collections based on estimated losses resulting from the inability or unwillingness of customers to make required payments. The allowance is estimated at each reporting period based upon historical loss patterns, the number of days that billings are past due and an evaluation of the potential risk of loss associated with specific delinquent accounts. The Company also considers any changes to the financial condition of its customers and any other external market factors that could impact the collectability of its receivables in the determination of its allowance for doubtful accounts. Concentration of Credit Risk and of Significant Customers Financial instruments that potentially expose the Company to concentrations of credit risk consist primarily of cash and trade accounts receivable. Although the Company maintains its cash balances with accredited financial institutions, the Company had substantially all cash balances at financial institutions without or in excess of federally insured limits at December 31, 2015 and 2014. The Company does not believe it is subject to unusual credit risk beyond the normal credit risk associated with commercial banking relationships. No individual customer accounted for more than 10% of total subscription revenue for the years ended December 31, 2015, 2014, and 2013, and no individual customer accounted for more than 10% of net accounts receivable at December 31, 2015, 2014, and 2013. Property and Equipment Property and equipment are stated at cost less accumulated depreciation or amortization. Depreciation and amortization is recognized using the straight-line method over the following estimated useful lives: In-vehicle devices—installed 4–6 years Computer equipment 3 years Internal-use software 3 years Furniture and fixtures 4–6 years Building 40 years Leasehold improvements Shorter of life of lease or For in-vehicle devices of which the Company retains ownership after they are installed in a customer’s fleet, the cost of the in-vehicle devices (including installation and shipping costs) is capitalized as property and equipment. The Company depreciates these costs over the minimum estimated useful life of the devices or over the estimated average customer relationship period, which are both currently six years, beginning upon completion of installation. Related depreciation expense is recorded in cost of subscription revenue. If a customer subscription agreement is canceled or expires prior to the end of the expected useful life of the in-vehicle device, the carrying value of the asset is depreciated in full with expense immediately recorded as cost of subscription revenue. Before installation in a customer’s fleet, in-vehicle devices of which the Company retains ownership are recorded within property and equipment (referred to as In-vehicle devices—uninstalled), but are not depreciated. Furthermore, due to the decommissioning of one of our primary network wireless providers’ 2G network, during 2014 we began capitalizing the cost of the replacement units in accordance with the capitalization for in-vehicle device costs accounting policy previously disclosed. Any remaining net book value of the replaced 2G units will be fully depreciated at the time of replacement with the 3G units. We expect to have the customer migration completed by the end of 2016. At each reporting period, the Company tests in-vehicle devices—installed for realizability through a review of customer accounts to identify (i) any significant changes in the financial condition of its customers, (ii) any customers who are past due on subscription payments owed and could become a credit risk, and (iii) any customers whose contract will be expiring without a follow-on renewal prior to the end of the estimated useful life of the in-vehicle device. If an impairment of the value of the in-vehicle device is identified, the carrying value of the in-vehicle device is depreciated in full, with expense immediately recorded as cost of subscription revenue. Amortization of leasehold improvements is computed on a straight-line basis over the shorter of the lease term or the estimated useful lives of the improvements. Assets held under capital leases are stated at the lesser of the present value of future minimum lease payments or the fair value of the leased asset at the inception of the lease. Amortization of assets under capital leases is computed using the straight-line method over the shorter of the estimate useful life of the asset or the period of the related lease. The cost of expenditures for maintenance and repairs of assets is charged to expense as incurred. Upon retirement or sale, the cost and related accumulated depreciation or amortization of assets disposed of are removed from the accounts and any resulting gain or loss is credited or charged to the consolidated statements of operations. Land is stated at cost and is not depreciated. Internal-Use Software Research and development costs are expensed as incurred, except for certain costs which are capitalized in connection with the development of its internal-use software and website. These capitalized costs are primarily related to the application software that is hosted by the Company and accessed by its customers through the Company’s website. In addition, the Company capitalizes certain general and administrative costs related to the customization and development of our internal business systems. Costs incurred in the preliminary stages of development are expensed as incurred. Once an application has reached the development stage, internal and external costs, if direct and incremental, are capitalized until the software is substantially complete and ready for its intended use. Capitalization ceases upon completion of all substantial testing performed to ensure the product is ready for its intended use. The Company also capitalizes costs related to specific upgrades and enhancements of internal-use software when it is probable that the expenditures will result in additional functionality. Maintenance and training costs are expensed as incurred. Capitalized internal-use software costs are recorded as part of property and equipment and are amortized on a straight-line basis over an estimated useful life of three years. Business Combinations In an acquisition of a business, the Company recognizes separately from goodwill the fair value of assets acquired and the liabilities assumed. Goodwill as of the acquisition date is measured as the excess of consideration transferred over the net of the acquisition-date fair values of the assets acquired and liabilities assumed. Transaction costs related to business combinations are expensed as incurred. In addition, uncertain tax positions assumed and valuation allowances related to the net deferred tax assets acquired in connection with a business combination are estimated as of the acquisition date and recorded as part of the purchase. Thereafter, any changes to these uncertain tax positions and valuation allowances are recorded as part of the provision for income taxes in the consolidated statements of operations. Goodwill and Other Intangible Assets The Company records goodwill when the consideration paid in a business acquisition exceeds the fair value of the net tangible assets acquired, identifiable intangible assets acquired and liabilities assumed. Goodwill is not amortized. Definite-lived intangible assets subject to amortization include customer relationships, trademarks, acquired developed technology, and a patent for the Company’s vehicle tracking system. Intangible assets acquired in a business combination are recorded under the acquisition method of accounting at their estimated fair values at the date of acquisition. Customer relationships, trademarks and acquired developed technology are amortized over their estimated useful lives, which range from three to nine years, based on a straight-line method or based on the pattern over which the Company expects to consume the economic benefit of each asset, which in general reflects the expected cash flows from each asset. The patent is amortized over its useful life of 20 years on a straight-line basis, as the pattern of consumption of the economic benefit of the asset cannot be reliably determined. Impairment of Goodwill and Long-Lived Assets Goodwill is tested for impairment annually or more frequently if events or circumstances occur that indicate an impairment may exist. Factors the Company considers important that could trigger an impairment review include significant underperformance relative to historical or projected operating results, significant changes in the Company’s use of the acquired assets in a business combination or the strategy for its overall business, and significant negative industry or economic trends. The Company performs its annual assessment for impairment of goodwill on October 31 and has determined it has a single reporting unit for testing goodwill for impairment. For purposes of assessing potential impairment, the Company first estimates the fair value of the reporting unit (based on the fair value of the Company’s outstanding ordinary shares) and compares that amount to the carrying value of the reporting unit (as reflected by the total carrying values of the Company’s shareholders’ equity. If the Company determines that the carrying value of the reporting unit exceeds its fair value, then the implied fair value of the goodwill is determined in the same manner used to determine the amount of goodwill in a business combination. If the carrying value of goodwill exceeds the implied fair value of the goodwill, an impairment charge is recognized in the amount equal to that excess. We have assigned the entire balance of goodwill to our one reporting unit. The fair value of the reporting unit was based on our market capitalization as of each of December 31, 2015 and 2014, and it was substantially in excess of the carrying value of the reporting unit at each date. No goodwill impairment charges were recorded during the years ended December 31, 2015, 2014, and 2013. Long-lived assets include property and equipment and definite-lived intangible assets subject to amortization. The Company evaluates its long-lived assets for recoverability whenever events or changes in circumstances indicate that their carrying values may not be recoverable. Factors that the Company considers in deciding when to perform an impairment review include significant underperformance of the business or product line in relation to expectations, significant negative industry or economic trends, and significant changes or planned changes in the use of the assets. To evaluate a long-lived asset for recoverability, the Company compares forecasts of undiscounted cash flows expected to result from the use and eventual disposition of the long-lived asset to its carrying value. If the carrying value exceeds the sum of the expected undiscounted cash flows, an impairment loss on the long-lived asset to be held and used is recognized based on the excess of the asset’s carrying value over its fair value, determined based on discounted cash flows. Long-lived assets to be disposed of are reported at the lower of carrying value or fair value less cost to sell. Subscription Revenue Recognition The Company provides access to its fleet management software through subscription arrangements whereby the customer is charged a per subscribed-vehicle fee for access for a specified term. The Company provides access to its field service management software through subscription arrangements whereby the customer is charged a per field service worker fee for access for a specified term. Subscription agreements contain multiple service elements and deliverables, including installation of in-vehicle devices, access to the Company’s on-demand software via its website, and support services delivered over the term of the arrangement. Agreements do not provide customers the right to take possession of the software at any time. The Company has determined that the elements of its subscription agreements do not have value to the customer on a standalone basis. As a result, the multiple elements within the subscription agreements do not qualify for treatment as separate units of accounting. Accordingly, the Company accounts for all fees received under its subscription agreements as a single unit of accounting and, except for any up-front fees, recognizes the total fee amount ratably on a daily basis over the term of the subscription agreement. The Company only commences recognition of revenue when there is persuasive evidence of an arrangement, the fee is fixed or determinable, collectability is deemed reasonably assured, and recurring services have commenced. The Company’s contract terms generally are 36 months for fleet management customers and 12 months for field service management customers for their initial term with automatic renewals for one or three years thereafter, unless the customer elects not to renew. For the limited number of fleet management customer arrangements in which title to the in-vehicle devices transfers to the customer upon delivery or installation of the in-vehicle device, the Company receives an up-front fee from the customer. As the in-vehicle devices do not have value to the customer on a standalone basis, the delivery or installation of the in-vehicle devices does not represent the culmination of a separate earning process associated with the payment of the up-front fee. Accordingly, the Company records the amount of the up-front fee as deferred revenue upon invoicing and recognize that amount as revenue ratably on a daily basis over the estimated average customer relationship period of six years, which is longer than the typical initial subscription agreement term of 36 months. If a customer permanently ceases use of the Company’s subscription service at any point when a balance of deferred revenue from this up-front payment exists, the Company recognizes the remaining balance of the deferred revenue in the period of notification. Changes in the typical customer contractual term, customer behavior, competition or economic conditions could affect the Company’s estimates of the average customer relationship period. The Company reviews the estimated average customer relationship period on a periodic basis and account for changes prospectively. In the majority of its sales transactions, the Company retains ownership of the in-vehicle device, and consequently the Company does not sell the device to the customer. Deferred Revenue Deferred revenue represents amounts billed to customers or payments received from customers for which revenue has not yet been recognized. Deferred revenue primarily consists of prepayments made by customers for future periods and, to a lesser extent, the unearned portion of monthly billed subscription fees and up-front payments from customers for in-vehicle devices whose ownership transfers to them upon delivery or installation. The Company’s payment terms are typically monthly in advance; however, the Company continues to enable its customers to prepay all or part of their contractual obligations quarterly, annually or for the full contract term in exchange for a prepayment discount that is reflected in the pricing of the contract. As a result, the deferred revenue balance does not represent the total contract value of all multi-year, non-cancelable subscription agreements. In the consolidated balance sheets, deferred revenue that is expected to be recognized within one year is recorded as current deferred revenue while the remaining portion is recorded as non-current deferred revenue. Deferred Commissions The Company capitalizes commission costs that are incremental and directly related to the acquisition of customer contracts. For the majority of its customer contracts, the Company pays commissions in full when it receives the initial customer contract for a new subscription or a renewal subscription. For all other customer contracts, the Company pays commissions in full when it receives the initial customer payment for a new subscription or a renewal subscription. Commission costs are capitalized upon payment and are amortized as expense ratably over the term of the related non-cancelable customer contract, in proportion to the recognition of the subscription revenue. If a subscription agreement is terminated, the unamortized portion of any deferred commission cost is recognized as expense immediately. Commission costs capitalized during the years ended December 31, 2015 and 2014 totaled $12,275 and $11,995, respectively. Amortization of deferred commissions totaled $10,194, $8,175 and $6,119 for the years ended December 31, 2015, 2014, and 2013, respectively, and is included in sales and marketing expense in the consolidated statements of operations. Deferred commission costs, net of amortization, are included in other current and long-term assets in the consolidated balance sheets and totaled $17,518 and $15,496 as of December 31, 2015 and 2014, respectively. Foreign exchange differences also contribute to changes in the net amount of these deferred commission costs. Capitalized In-Vehicle Device Costs For the limited number of customer arrangements in which title to the in-vehicle devices transfers to the customer upon delivery or installation of the in-vehicle device (for which the Company receives an up-front fee from the customer), the Company defers the costs of the installed in-vehicle devices (including installation and shipping costs) as they are directly related to the revenue that the Company derives from the sale of the devices and that it recognizes ratably over the estimated average customer relationship period of six years. The Company capitalizes these in-vehicle device costs and amortizes the deferred costs as expense ratably over the estimated average customer relationship period, in proportion to the recognition of the up-front fee revenue. Costs of in-vehicle devices owned by customers that were capitalized during the years ended December 31, 2015 and 2014 totaled $392 and $149, respectively. Amortization of these capitalized costs totaled $682, $1,123, and $960 for the years ended December 31, 2015, 2014, and 2013, respectively, and is included in cost of subscription revenue in the consolidated statements of operations. Capitalized costs related to these in-vehicle devices of which title has transferred to customers, net of amortization, are included in other current and long-term assets in the consolidated balance sheet which totaled $2,398 as of December 31, 2014 As of December 31, 2015, we no longer enter into customer arrangements whereby title to the in-vehicle devices transfers to the customer upon delivery or installation of the in-vehicle device. Income Taxes The Company accounts for income taxes using the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been recognized in the financial statements or in the Company’s tax returns. Deferred taxes are determined based on the difference between the financial statement and tax basis of assets and liabilities using enacted tax rates in effect in the years in which the differences are expected to reverse. Changes in deferred tax assets and liabilities are recorded in the provision for income taxes. The Company assesses the likelihood that its deferred tax assets will be recovered from future taxable income and, to the extent it believes, based upon the weight of available evidence, that it is more likely than not that all or a portion of deferred tax assets will not be realized, a valuation allowance is established through a charge to income tax expense. Potential for recovery of deferred tax assets is evaluated by estimating the future taxable profits expected from each subsidiary and considering prudent and feasible tax planning strategies. The Company accounts for uncertainty in income taxes recognized in its financial statements by applying a two-step process to determine the amount of tax benefit to be recognized. First, the tax position must be evaluated to determine the likelihood that it will be sustained upon examination by the taxing authorities, based on the technical merits of the position. If the tax position is deemed more-likely-than-not to be sustained, the tax position is then assessed to determine the amount of benefit to recognize in the financial statements. The amount of the benefit that may be recognized is the largest amount that has a greater than 50% likelihood of being realized upon ultimate settlement. The provision for income taxes includes the effects of any resulting tax reserves, or unrecognized tax benefits, that are considered appropriate as well as the related net interest and penalties. Foreign Currency Translation The Company’s reporting currency is the U.S. dollar. The Company has subsidiaries in the United States, Ireland, the United Kingdom, Australia, Mexico, Italy, France, Poland and The Netherlands. The functional currency for each of the Company’s subsidiaries is the local currency. For those subsidiaries whose functional currency is not the U.S. dollar, assets and liabilities are translated into U.S. dollar equivalents at the exchange rate in effect on the balance sheet date and revenues from customers and expenses incurred are translated into U.S. dollars using the average exchange rate over the period. Resulting currency translation adjustments are recorded in accumulated other comprehensive income (loss) in the consolidated balance sheet. For the years ended December 31, 2015 and 2014, the Company recorded currency translation losses of $6,703 and $2,782, respectively, as foreign currency translation adjustments within shareholders’ equity. The Company also incurs transaction gains and losses resulting from intercompany transactions of a short-term nature as well as transactions with customers or vendors denominated in currencies other than the functional currency of the legal entity in which the transaction is recorded. Assets and liabilities arising from such transactions are translated into the legal entity’s functional currency using the exchange rate in effect at the balance sheet date. Any resulting transaction gains or losses are recorded as foreign currency transaction gain (loss) in the consolidated statements of operations. Net foreign currency transaction gains of $3,538, $832, and a loss of $1,139 were recorded for the years ended December 31, 2015, 2014 and 2013, respectively. The Company has concluded that its reporting currency is the U.S. dollar because the parent entity has received U.S. dollars upon the issuance of all equity securities to investors, the parent’s cash is held exclusively in U.S. dollar bank accounts, the parent’s intercompany transactions (primarily receivables from subsidiaries) are denominated in U.S. dollars, and a majority of its parent-related expenses are billed by vendors and paid in U.S. dollars. Share-Based Compensation The Company recognizes expense for stock options, market-based restricted stock awards and time-based restricted stock awards pursuant to ASC 718, “Compensation—Stock Compensation” (“ASC 718”), which requires recognition of share-based compensation expense in the statement of operations over the vesting period based on the fair value of the award at the grant date. The fair value of the awards is recognized as expense, net of estimated forfeitures, over the requisite service period, which is generally the vesting period of the respective award. The straight-line method of expense recognition is applied to all awards with service conditions, while the graded-vesting method of expense recognition is applied to all awards with both service and performance conditions. The Company classifies share-based compensation expense in the consolidated statements of operations in the same manner in which the award recipient’s payroll costs are classified. The Company has share-based employee compensation plans which are described more fully in Note 14 to these consolidated financial statements. Advertising Expense Advertising costs are expensed as incurred. Advertising expense was $20,413, $18,864 and $11,097 for the years ended December 31, 2015, 2014 and 2013, respectively, and was included in sales and marketing expense in the consolidated statements of operations. Comprehensive Income (Loss) Comprehensive income (loss) is comprised of net income (loss) and other comprehensive income (loss), which includes certain changes in shareholders’ equity that are excluded from net income (loss). For the years ended December 31, 2015, 2014 and 2013, the only item qualifying as other comprehensive income (loss) was foreign currency translation. For purposes of comprehensive income (loss) computations, the Company does not record income tax provisions or benefits for foreign currency translation adjustments as the Company intends to permanently reinvest undistributed earnings of its foreign subsidiaries in the United States and the United Kingdom. As of December 31, 2015, the Company’s material foreign subsidiaries in the United States and the United Kingdom had no undistributed earnings. Net Income (Loss) Per Share Basic net income (loss) per share attributable to ordinary shareholders is computed by dividing the net income (loss) attributable to ordinary shareholders by the weighted average number of ordinary shares outstanding for the period. Diluted net income (loss) per share attributable to ordinary shareholders is computed by dividing the diluted net income (loss) attributable to ordinary shareholders by the weighted average number of ordinary shares, including potential dilutive ordinary shares assuming the dilutive effect of outstanding stock options and unvested restricted ordinary shares, as determined using the treasury stock method. For periods in which the Company has reported net losses, diluted net loss per ordinary share attributable to ordinary shareholders is the same as basic net loss per ordinary share attributable to ordinary shareholders, since dilutive ordinary shares are not assumed to have been issued if their effect is antidilutive.
