Accounting Policies [Abstract] |
Basis of Presentation | Basis of Presentation The Company has recently incurred operating losses and had a net loss attributable to common shareholders of $60.6 million during the year ended December 31, 2016. As of December 31, 2016, the Company had available cash and cash equivalents totaling $9.9 million, and working capital of $6.1 million. The Company’s ability to transition towards attaining profitable operations is dependent upon achieving a level of revenues adequate to support its cost structure. If events or circumstances occur such that the Company does not meet its operating plan as expected, the Company may be required to reduce planned research and development activities, incur additional restructuring charges or reduce other operating expenses which could have an adverse impact on its ability to achieve its intended business objectives. These additional reductions in expenditures, if required, could have an adverse impact on the Company’s ability to achieve certain of its business objectives. The Company’s management believes that its cash and cash equivalents and availability under its revolving credit facility, together with anticipated cash flows from operations and proceeds from the completion of the pending sale of the MiFi Business, will be sufficient to meet its working capital needs for the next twelve months following the filing date of this report. The Company’s historical operating results, primarily those related to the MiFi Business, indicate that substantial doubt exists related to the Company’s ability to continue as a going concern. The Company’s management believes that the closing of the sale of the MiFi Business is probable of occurring and mitigating the substantial doubt raised by the Company’s historical operating results and will satisfy its liquidity needs for the twelve months following the filing date of this report. In the unlikely event that the sale of the MiFi Business does not close, the Company would require an alternative source of financing to divest the MiFi Business elsewhere or to otherwise streamline the MiFi Business as may be needed. The Company has had discussions with potential financing sources, and the Company’s management believes that it is probable that such financing would be available to the Company based on terms that have been presented to the Company by financial sources. The Company cannot predict, with certainty, the outcome of the sale of the MiFi Business or any other activities to generate liquidity, including the availability of additional financing. If the Company is not able to generate additional liquidity through the mechanisms described above or through some combination of other actions, while not expected, the Company may not be able to access funds under its Revolver, and may need to secure additional sources of funds, which may or may not be available to the Company. Additionally, a failure to generate additional liquidity could negatively impact the Company’s access to production, inventory or services that are important to the operation of its business.
Principles of Consolidation | Principles of Consolidation The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany transactions and balances have been eliminated in consolidation.
Use of Estimates | Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions. These estimates and assumptions affect the reported amounts of assets, liabilities, revenues and expenses, and disclosure of contingent liabilities. Actual results could differ materially from these estimates. Significant estimates include allowance for doubtful accounts receivable, provision for excess and obsolete inventory, valuation of intangible and long-lived assets, valuation of goodwill, valuation of debt obligations, royalty costs, accruals relating to litigation and restructuring, provision for warranty costs, income taxes, share-based compensation expense and the Company’s ability to continue as a going concern.
Segment Information | Segment Information The Company does not provide separate segment reporting for its various lines of business. The Chief Executive Officer, who is also the Chief Operating Decision Maker, evaluates the business as a single entity and reviews financial information and makes business decisions based on the overall results of the business. As such, the Company's operations constitute a single operating segment and one reportable segment.
Cash and Cash Equivalents | Cash and Cash Equivalents Cash and cash equivalents include highly liquid investments with original maturities of three months or less. The Company’s cash and cash equivalents consist of money market funds. Cash and cash equivalents are recorded at market value, which approximates cost. Gains and losses associated with the Company’s foreign currency denominated demand deposits are recorded as a component of other income (expense), net, in the consolidated statements of operations.
Allowance for Doubtful Accounts Receivable | Allowance for Doubtful Accounts Receivable The Company provides an allowance for its accounts receivable for estimated losses that may result from its customers’ inability to pay. The Company determines the amount of the allowance by analyzing known uncollectible accounts, aged receivables, economic conditions, historical losses, and changes in customer payment cycles and its customers’ credit-worthiness. Amounts later determined and specifically identified to be uncollectible are charged or written off against this allowance. To minimize the likelihood of uncollectibility, the Company reviews its customers’ credit-worthiness periodically based on credit scores generated by independent credit reporting services, its experience with its customers and the economic condition of its customers’ industries. Material differences may result in the amount and timing of expense for any period if the Company were to make different judgments or utilize different estimates.
Inventories and Provision for Excess and Obsolete Inventory | Inventories and Provision for Excess and Obsolete Inventory Inventories are stated at the lower of cost (first-in, first-out method) or market. Shipping and handling costs are classified as a component of cost of net revenues in the consolidated statements of operations. The Company reviews the components of its inventory and its inventory purchase commitments on a regular basis for excess and obsolete inventory based on estimated future usage and sales. Write-downs in inventory value or losses on inventory purchase commitments depend on various items, including factors related to customer demand, economic and competitive conditions, technological advances or new product introductions by the Company or its customers that vary from its current expectations. Whenever inventory is written down, a new cost basis is established and the inventory is not subsequently written up if market conditions improve. The Company believes that, when made, the estimates used in calculating the inventory provision are reasonable and properly reflect the risk of excess and obsolete inventory. If customer demand for the Company’s inventory is substantially less than its estimates, inventory write-downs may be required, which could have a material adverse effect on its consolidated financial statements.
Property, Plant and Equipment | Property, Plant and Equipment Property, plant and equipment are initially stated at cost and depreciated using the straight-line method. Test equipment, computer equipment, purchased software, furniture and fixtures, product tooling and vehicles are depreciated over lives ranging from eighteen months to six years. Leasehold improvements are depreciated over the shorter of the related remaining lease period or useful life. Buildings are depreciated over 50 years. Land is not depreciated. Amortization of equipment under capital leases is included in depreciation expense. Expenditures for repairs and maintenance are expensed as incurred. Expenditures for major renewals and betterments that extend the useful lives of existing property, plant and equipment are capitalized and depreciated. Upon retirement or disposition of property, plant and equipment, any resulting gain or loss is recognized in other income (expense), net, in the consolidated statements of operations. Rental Assets The cost of rental assets, which represents fleet management and vehicle tracking solutions installed in customers’ vehicles where hardware is provided as part of a fixed term contract with the customer, is capitalized and disclosed separately in the consolidated balance sheets. The Company depreciates rental assets to costs of net revenues on a straight-line basis over the term of the contract, generally three to four years, commencing on installation of the rental asset.
Software Development Costs and Internal Use Software | Software Development Costs Software development costs are expensed as incurred until technological feasibility has been established, at which time those costs are capitalized as intangible assets until the software is implemented into products sold to customers. Capitalized software development costs are amortized on a straight-line basis over the estimated useful life of the software (see Note 4). Costs incurred to enhance existing software or after the implementation of the software into a product are expensed in the period they are incurred and included in research and development expense in the consolidated statements of operations. Internal Use Software Costs incurred in the preliminary stages of development are expensed as incurred and included in research and development expense in the consolidated statements of operations. 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, plant and equipment and are amortized on a straight-line basis over the estimated useful life of the software, which is generally five years. The Company does not capitalize pilot projects and projects for which it believes that the future economic benefits are less than probable. The Company tests these assets for impairment whenever events or circumstances occur that could impact their recoverability.
Intangible Assets | Intangible Assets Intangible assets include purchased finite-lived and indefinite-lived intangible assets resulting from the acquisitions of DigiCore Holdings Limited (“DigiCore” or “Ctrack”), Feeney Wireless, LLC (“FW”) and Enfora, Inc. (“Enfora”), along with the costs of non-exclusive and perpetual worldwide software technology licenses and capitalized software developments costs. Finite-lived intangible assets are amortized on on a straight-line basis over the estimated useful lives of the assets (see Note 4). Indefinite-lived assets, including goodwill, in-process research and development and in-process capitalized software development costs, are not amortized; however, they are tested for impairment annually and between annual tests if certain events occur indicating that the carrying amounts may be impaired. If a qualitative assessment is used and the Company determines that the fair value of an indefinite-lived intangible asset is more likely than not (i.e., a likelihood of more than 50%) less than its carrying amount, a quantitative impairment test will be performed. If indefinite-lived intangible assets are quantitatively assessed for impairment, a two-step approach is applied. First, the Company compares the estimated fair value of the indefinite-lived intangible asset to its carrying value. The second step, if necessary, measures the amount of such impairment by comparing the implied fair value of the asset to its carrying value.
Long-Lived Assets | Long-Lived Assets The Company periodically evaluates the carrying value of the unamortized balances of its long-lived assets, including property, plant and equipment, rental assets and intangible assets, to determine whether impairment of these assets has occurred or whether a revision to the related amortization periods should be made. When the carrying value of an asset exceeds the associated undiscounted expected future cash flows, it is considered to be impaired and is written down to fair value. Fair value is determined based on an evaluation of the assets associated undiscounted future cash flows or appraised value. This evaluation is based on management’s projections of the undiscounted future cash flows associated with each class of asset. If management’s evaluation indicates that the carrying values of these assets are impaired, such impairment is recognized by a reduction of the applicable asset carrying value to its estimated fair value and the impairment is expensed as a part of continuing operations.
Derivative Financial Instruments | Derivative Financial Instruments The Company evaluates stock options, stock warrants and other contracts to determine if those contracts or embedded components of those contracts qualify as derivative financial instruments to be separately accounted for under the relevant sections of the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”). The result of this accounting treatment could be that the fair value of a financial instrument is classified as a derivative financial instrument and is marked-to-market at each balance sheet date and recorded as an asset or liability. In the event that the fair value is recorded as an asset or liability, the change in fair value is recorded in the statement of operations as other income or other expense. Upon conversion, exercise or expiration of a derivative financial instrument, the instrument is marked to fair value and then that fair value is reclassified to equity.
Acquisitions | Acquisitions When acquiring companies, the Company recognizes separately from goodwill the assets acquired and the liabilities assumed at their acquisition date fair values. Goodwill as of the acquisition date is measured as the excess of consideration transferred and the net of the acquisition date fair values of the assets acquired and the liabilities assumed. While the Company uses its best estimates and assumptions as a part of the purchase price allocation process to accurately value assets acquired and liabilities assumed at the acquisition date, the Company’s estimates are inherently uncertain and subject to refinement. As a result, during the measurement period, which may be up to one year from the acquisition date, the Company records adjustments to the assets acquired and liabilities assumed, with the corresponding offset to goodwill. Upon the conclusion of the measurement period or final determination of the values of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded to the consolidated statements of operations. Accounting for business combinations requires the Company’s management to make significant estimates and assumptions, especially at the acquisition date with respect to intangible assets, support liabilities assumed, and pre-acquisition contingencies. Although the Company believes the assumptions and estimates it has made in the past have been reasonable and appropriate, they are based in part on historical experience, market data and information obtained from the management of the acquired companies and are inherently uncertain. Examples of critical estimates in valuing certain of the intangible assets the Company has acquired include but are not limited to: (i) future expected cash flows from customer relationships; (ii) estimates to develop or use technology; and (iii) discount rates. If the Company determines that a pre-acquisition contingency is probable in nature and estimable as of the acquisition date, the Company records its best estimate for such a contingency as a part of the preliminary fair value allocation. The Company continues to gather information for and evaluate pre-acquisition contingencies throughout the measurement period and if the Company makes changes to the amounts recorded or if the Company identifies additional pre-acquisition contingencies during the measurement period, such amounts will be included in the fair value allocation during the measurement period and, subsequently, in the Company’s results of operations. The Company may be required to pay future consideration to the former shareholders of acquired companies, depending on the terms of the applicable purchase agreements, which may be contingent upon the achievement of certain financial and operating targets, as well as the retention of key employees. If the future consideration is considered to be compensation, amounts will be expensed when incurred.
Divestitures | Divestitures Gains or losses from divested operations and assets that do not qualify for treatment as discontinued operations under ASC 205-20, Presentation of Financial Statements—Discontinued Operations, are recorded as other income (expense), net, in the consolidated statements of operations.
Restructuring | Restructuring The Company accounts for facility exit costs in accordance with ASC 420, Exit or Disposal Cost Obligations, which requires that a liability for such costs be recognized and measured initially at fair value on the cease-use date based on remaining lease rentals, adjusted for the effects of any prepaid or deferred items recognized, reduced by the estimated sublease rentals that could be reasonably obtained even if the Company does not intend to sublease the facilities. The Company is required to estimate future sublease income and future net operating expenses of the facilities, among other expenses. The most significant of these estimates relate to the timing and extent of future sublease income which reduce lease obligations, and the probability that such sublease income will be realized. The Company based estimates of sublease income, in part, on information from third party real estate experts, current market conditions and rental rates, an assessment of the time period over which reasonable estimates could be made, and the location of the respective facility, among other factors. Further adjustments to the facility exit liability accrual will be required in future periods if actual exit costs or sublease income differ from current estimates. Exit costs recorded by the Company under these provisions are neither associated with, nor do they benefit, continuing activities.
Convertible Debt | Convertible Debt The Company accounts for its convertible debt instruments that are settleable in cash upon conversion (including partial cash settlement) by separating the liability and equity components of the instruments in a manner that reflects the Company’s nonconvertible debt borrowing rate. The Company determines the carrying amount of the liability component by measuring the fair value of similar debt instruments that do not have the conversion feature. If a similar debt instrument does not exist, the Company estimates the fair value by using assumptions that market participants would use in pricing a debt instrument, including market interest rates, credit standing, yield curves and volatilities. Determining the fair value of the debt component requires the use of accounting estimates and assumptions. These estimates and assumptions are judgmental in nature and could have a significant impact on the determination of the debt component and the associated non-cash interest expense. Upon issuance, the Company assigns a value to the debt component equal to the estimated fair value of similar debt instruments without the conversion feature, which could result in the Company recording the debt instrument at a discount. If the debt instrument is recorded at a discount, the Company amortizes the debt discount over the life of the debt instrument as additional non-cash interest expense utilizing the effective interest method.
Revenue Recognition | Revenue Recognition During the year ended December 31, 2016, the Company generated a portion of its revenue from the sale of wireless modems to wireless operators, OEM customers and value added resellers and distributors. In addition, the Company generates revenue from the sale of asset-management solutions utilizing wireless technology and M2M communication devices predominantly to transportation and industrial companies, medical device manufacturers and security system providers. Revenue from product sales is generally recognized upon the later of transfer of title or delivery of the product to the customer. Where the transfer of title or risk of loss is contingent on the customer’s acceptance of the product, the Company will not recognize revenue until both title and risk of loss have transferred to the customer. Revenues from SaaS services are recognized pro-rata over the contract term. The Company records deferred revenue for cash payments received from customers in advance of when revenue recognition criteria are met. The Company has granted price protection to certain customers in accordance with the provisions of the respective contracts and tracks pricing and other terms offered to customers buying similar products to assess compliance with these provisions. The Company estimates the amount of price protection for current period product sales utilizing historical experience and information regarding customer inventory levels. To date, the Company has not incurred material price protection obligations. Revenues from sales to certain customers are subject to cooperative advertising allowances. Cooperative advertising allowances are recorded as an operating expense to the extent that the advertising benefit is separable from the revenue transaction and the fair value of that advertising benefit is determinable. To the extent that such allowances either do not provide a separable benefit to the Company, or the fair value of the advertising benefit cannot be reliably estimated, such amounts are recorded as a reduction of revenue. The Company establishes a reserve for estimated product returns allowances in the period in which revenue is recognized. In estimating future product returns, the Company considers various factors, including its stated return policies and practices and historical trends. Certain of the Company’s revenues represent the sale of hardware with accompanied software that is essential to the functionality of the hardware. In such instances, the Company records revenue associated with the agreed upon price on hardware sales, and accrues any estimated costs of post-delivery performance obligations such as warranty obligations. The Company considers the four basic revenue recognition criteria when assessing appropriate revenue recognition as follows: Criterion #1 — Persuasive evidence of an arrangement must exist; Criterion #2 — Delivery has occurred; Criterion #3 — The seller’s price to the buyer must be fixed or determinable; and Criterion #4 — Collectability is reasonably assured. For multiple element arrangements, total consideration received from customers is allocated to the elements. This may include hardware, leased elements, non-essential software elements and/or essential software, based on a relative selling price. The accounting guidance establishes a hierarchy to determine the selling price to be used for allocating revenue to deliverables as follows: (i) vendors specific objective evidence (“VSOE”), (ii) third party evidence (“TPE”), and (iii) best estimate of selling price (“BESP”). Because the Company has neither VSOE nor TPE, revenue has been based on the Company’s BESP. Amounts allocated to the delivered hardware and the related essential software are recognized at the time of the sale provided all other revenue recognition criteria have been met. Amounts allocated to other deliverables based upon BESP are recognized in the period the revenue recognition criteria have been met. The Company’s process for determining its BESP for deliverables without VSOE or TPE considers multiple factors that may vary depending upon the unique facts and circumstances related to each deliverable. The Company’s prices are determined based upon cost to produce the products, expected order quantities, acceptance in the marketplace and internal pricing parameters. In addition, when developing BESPs for products the Company may consider other factors as appropriate including the pricing of competitive alternatives if they exist, and product-specific business objectives. The Company accounts for nonessential software licenses and related post contract support (“PCS”) under multiple element arrangements by recognizing revenue for such arrangements ratably over the term of the PCS as it has not established VSOE for the PCS element. The Company provides SaaS subscriptions for its fleet management and vehicle finance applications in which customers are provided with the ability to wirelessly communicate with monitoring devices installed in vehicles and other mobile assets via software applications hosted by the Company. The customer has the option to purchase the monitoring device or lease it over the term of the contract. If the customer purchases the monitoring device, the Company recognizes the revenue at the time of purchase. If the customer chooses to lease the monitoring device, the Company recognizes the revenue for the monitoring device over the term of the contract, which is generally three years. The Company records such revenue in accordance with ASC 840, Leases, as it has determined that they qualify as operating leases. The Company recognizes revenues from SaaS services over the term of the contract. Certain of the Company’s revenue is based on contractual arrangements. In such instances, management considers the nature of the Company's contractual arrangements in determining whether to recognize certain types of revenue on the basis of the gross amount billed or net amount retained after payments are made to providers of certain services related to the product or service offering. The main factors the Company uses to determine whether to record revenue on a gross or net basis are whether:
• | the Company is primarily responsible for the service to the customer;
• | the Company has discretion in establishing fees paid by the customer; and
• | the Company is involved in the determination of product or service specifications.
When the customer’s fee includes a portion of charges that are paid to another party and the Company is primarily responsible for providing the service to the customer, revenue is recognized on a gross basis in an amount equal to the fee paid by the customer. The cost of revenues recognized is the amount due to the other party and is recorded as cost of revenues in the consolidated statements of operations. In instances in which another party is primarily responsible for providing the service to the customer, revenue is recognized in the net amount retained by the Company. The portion of the fees that are collected from the customer by the Company and remitted to the other party are considered pass through amounts and accordingly are not a component of net revenues or cost of net revenues. The Company occasionally enters into transactions where it provides consideration to its customers in the form of credits for certain raw materials received that are used in the finished goods purchased by the same customer. The Company accounts for such credits to customers as a reduction of net revenues because it is unable to demonstrate the receipt of a benefit that is identifiable and sufficiently separable from the revenue transaction and reasonably estimate the fair value of the benefit identified. Significant management judgment and estimates must be used to determine the fair value of the benefit received in any period.
Provision for Warranty Costs | Provision for Warranty Costs The Company accrues warranty costs based on estimates of future warranty related replacement, repairs or rework of products. The Company’s warranty policy generally provides one to three years of coverage for products following the date of purchase. The Company’s policy is to accrue the estimated cost of warranty coverage as a component of cost of revenue in the accompanying consolidated statements of operations at the time revenue is recognized. In estimating its future warranty obligations, the Company considers various factors, including the historical frequency and volume of claims and cost to replace or repair products under warranty. The warranty provision for the Company’s products is determined by using a financial model to estimate future warranty costs. The Company’s financial model takes into consideration actual product failure rates; estimated replacement, repair or rework expenses; and potential risks associated with its different products. The risk levels, warranty cost information and failure rates used within this model are reviewed throughout the year and updated, if and when, these inputs change.
Foreign Currency Transactions and Translation | Foreign Currency Transactions Foreign currency transactions are transactions denominated in a currency other than a subsidiary’s functional currency. A change in the exchange rates between a subsidiary’s functional currency and the currency in which a transaction is denominated increases or decreases the expected amount of functional currency cash flows upon settlement of the transaction. That increase or decrease in expected functional currency cash flows is reported by the Company as a foreign currency transaction gain (loss). The primary component of the Company’s foreign currency transaction gain (loss) is due to agreements in place with certain subsidiaries in foreign countries regarding intercompany transactions. Based upon historical experience, the Company anticipates repayment of these transactions in the foreseeable future, and recognizes the realized and unrealized gains (losses) on these transactions that result from foreign currency changes in the period in which they occur as foreign currency transaction gain (loss), which is recorded as other income (expense), net, in the consolidated statements of operations. Foreign Currency Translation Assets and liabilities of the Company’s international subsidiaries in which the local currency is the functional currency are translated into U.S. Dollars at period-end exchange rates. Income and expenses are translated into U.S. Dollars at the average exchange rates during the period. The resulting translation adjustments are included in the Company’s consolidated balance sheets as a component of accumulated other comprehensive loss.
Income Taxes | Income Taxes The Company recognizes federal, state and foreign current tax liabilities or assets based on its estimate of taxes payable to or refundable by tax authorities in the current fiscal year. The Company also recognizes federal, state and foreign deferred tax liabilities or assets based on the Company’s estimate of future tax effects attributable to temporary differences and carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. Deferred tax assets are reduced by valuation allowances if, based on the consideration of all available evidence, it is more likely than not that some portion of the deferred tax asset will not be realized. The Company evaluates deferred income taxes on a quarterly basis to determine if valuation allowances are required by considering available evidence. If the Company is unable to generate sufficient future taxable income in certain tax jurisdictions, or if there is a material change in the actual effective tax rates or time period within which the underlying temporary differences become taxable or deductible, the Company could be required to increase its valuation allowance against its deferred tax assets which could result in an increase in the Company’s effective tax rate and an adverse impact on operating results. The Company will continue to evaluate the necessity of the valuation allowance based on the remaining deferred tax assets. The Company follows the accounting guidance related to financial statement recognition, measurement and disclosure of uncertain tax positions. The Company recognizes the impact of an uncertain income tax position on an 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. Uncertain tax positions are recognized in the first subsequent financial reporting period in which that threshold is met or from changes in circumstances such as the expiration of applicable statutes of limitations.
Share-Based Compensation | Share-Based Compensation The Company has granted stock options to employees and restricted stock units. The Company also has an employee stock purchase plan (“ESPP”) for eligible employees. The Company measures the compensation cost associated with all share-based payments based on grant date fair values. The fair value of each employee stock option and employee stock purchase right is estimated on the date of grant using an option pricing model that meets certain requirements. The Company generally uses the Black-Scholes option pricing model to estimate the fair value of its stock options and stock purchase rights. The Black-Scholes model is considered an acceptable model but the fair values generated by it may not be indicative of the actual fair values of the Company’s equity awards as it does not consider certain factors important to those awards to employees, such as continued employment and periodic vesting requirements as well as limited transferability. The determination of the fair value of share-based payment awards utilizing the Black-Scholes model is affected by the Company’s stock price and a number of assumptions, including expected volatility, expected term, risk-free interest rate and expected dividends. For grants of stock options, the Company uses a blend of historical and implied volatility for traded options on its stock in order to estimate the expected volatility assumption required in the Black-Scholes model. The Company’s use of a blended volatility estimate in computing the expected volatility assumption for stock options is based on its belief that while the implied volatility is representative of expected future volatility, the historical volatility over the expected term of the award is also an indicator of expected future volatility. Due to the short duration of employee stock purchase rights under the Company’s ESPP, the Company utilizes historical volatility in order to estimate the expected volatility assumption of the Black-Scholes model. The expected term of stock options granted is estimated using historical experience. The risk-free interest rate assumption is based on observed interest rates appropriate for the expected terms of the Company’s stock options and employee stock purchase rights. The dividend yield assumption is based on the Company’s history and expectation of no dividend payouts. The Company estimates forfeitures at the time of grant and revises these estimates, if necessary, in subsequent periods if actual forfeitures differ from those estimates. The Company estimates its forfeiture rate assumption for all types of share-based compensation awards based historical forfeiture rates related to each category of award. Compensation cost associated with grants of restricted stock units are measured at fair value, which has historically been the closing price of the Company’s stock on the date of grant. The Company recognizes share-based compensation expense over the requisite service period of each individual award, which generally equals the vesting period, using the straight-line method for awards that contain only service conditions. For awards that contain performance conditions, the Company recognizes the share-based compensation expense on a straight-line basis for each vesting tranche. The Company evaluates the assumptions used to value stock awards on a quarterly basis. If factors change and the Company employs different assumptions, share-based compensation expense may differ significantly from what it has recorded in the past. If there are any modifications or cancellations of the underlying unvested securities, the Company may be required to accelerate, increase or cancel any remaining unearned share-based compensation expense.
Net Loss Per Share Attributable to Common Shareholders | Net Loss Per Share Attributable to Common Shareholders The Company computes basic and diluted per share data for all periods for which a statement of operations is presented. Basic net loss per share excludes dilution and is computed by dividing the net loss by the weighted-average number of shares that were outstanding during the period. Diluted EPS reflects the potential dilution that could occur if securities or other contracts to acquire common stock were exercised or converted into common stock. Potential dilutive securities are excluded from the diluted EPS computation in loss periods as their effect would be anti-dilutive. For all periods presented, there is no difference in the number of shares used to calculate basic and diluted shares outstanding due to the Company’s net loss position.
Fair Value of Financial Instruments | Fair Value of Financial Instruments The Company’s fair value measurements relate to its cash equivalents, marketable debt securities, and marketable equity securities, which are classified pursuant to authoritative guidance for fair value measurements. The Company places its cash equivalents and marketable debt securities in instruments that meet credit quality standards, as specified in its investment policy guidelines. These guidelines also limit the amount of credit exposure to any one issue, issuer or type of instrument. The Company’s financial instruments consist principally of cash and cash equivalents, short-term investments and long-term debt. The Company’s cash and cash equivalents consist of its investments in money market funds. From time to time, the Company may utilize foreign exchange forward contracts. These contracts are valued using pricing models that take into account the currency rates as of the balance sheet date.
Comprehensive Loss | Comprehensive Loss Comprehensive loss consists of net earnings, foreign currency translation adjustments and unrealized gains and losses on available-for-sale securities.
Recent Accounting Pronouncements | Recent Accounting Pronouncements From time to time, new accounting pronouncements are issued by the FASB, which are adopted by the Company as of the specified date. Unless otherwise discussed, management believes the impact of recently issued standards, which are not yet effective, will not have a material impact on its consolidated financial statements upon adoption. In January 2017, the FASB issued Accounting Standards Update (“ASU”) 2017-04, Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment, which simplifies the measurement of goodwill by eliminating the second step from the goodwill impairment test, which requires the comparison of the implied fair value of goodwill with the current carrying amount of goodwill. Instead, under the amendments in this guidance, an entity shall perform a goodwill impairment test by comparing the fair value of each reporting unit with its carrying amount and an impairment charge is to be recorded for the amount, if any, in which the carrying value exceeds the reporting unit’s fair value. This guidance should be applied prospectively and is effective for fiscal years beginning after December 15, 2019. Early adoption is permitted. The Company is currently assessing the impact of this guidance. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments, which clarifies how companies present and classify certain cash receipts and cash payments in the statement of cash flows. This guidance is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted. The Company is currently assessing the impact of this guidance. In June 2016, the FASB issued ASU 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which requires measurement and recognition of expected credit losses for financial assets held. This guidance is effective for interim and annual reporting periods beginning after December 15, 2019. Early adoption is permitted. The Company is currently assessing the impact of this guidance. In March 2016, the FASB issued ASU 2016-09, Improvements to Employee Share-Based Payment Accounting, which affects entities that issue share-based payment awards to their employees. The guidance is designed to identify areas for simplification involving several aspects of accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, an option to recognize gross stock compensation expense with actual forfeitures recognized as they occur, as well as certain classifications on the statement of cash flows. This guidance is effective prospectively for interim and annual periods beginning after December 15, 2016. Early adoption is permitted. The Company is currently assessing the impact of this guidance. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), which establishes the principles to report transparent and economically neutral information about the assets and liabilities that arise from leases. This guidance results in the Company providing a more faithful representation of the rights and obligations arising from operating and capital leases by requiring lessees to recognize the lease assets and lease liabilities that arise from leases in the statement of financial position and to disclose qualitative and quantitative information about lease transactions, such as information about variable lease payments and options to renew and terminate leases. This guidance is effective prospectively for interim and annual periods beginning after December 15, 2018. Early adoption is permitted. The Company is currently assessing the impact of this guidance. In September 2015, the FASB issued ASU 2015-16, Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments (“ASU 2015-16”), which eliminates the requirement for an acquirer to retrospectively adjust provisional amounts recorded in a business combination to reflect new information about the facts and circumstances that existed as of the acquisition date and that, if known, would have affected the measurement or recognition of amounts initially recognized. As an alternative, the update requires that an acquirer recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. The update requires that the acquirer record, in the financial statements of the period in which adjustments to provisional amounts are determined, the effect on earnings of changes in depreciation, amortization, or other income effects, if any, as a result of the change to the provisional amounts, calculated as if the accounting had been completed at the acquisition date. The Company implemented this guidance during the first quarter of 2016. This guidance did not have a material impact on the Company’s consolidated financial statements upon adoption. In April 2015, the FASB issued ASU 2015-05, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement. Under this standard, if a cloud computing arrangement includes a software license, the software license element of the arrangement should be accounted for consistent with the acquisition of other software licenses. If a cloud computing arrangement does not include a software license, the arrangement should be accounted for as a service contract. The Company implemented this guidance during the first quarter of 2016. This guidance did not have a material impact on the Company’s consolidated financial statements upon adoption. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”), which provides guidance for revenue recognition. The new standard will require revenue recognized to represent the transfer of promised goods or services to customers in an amount that reflects the consideration the company expects to receive in exchange for those goods or services. The standard also requires new, expanded disclosures regarding revenue recognition. In August 2015, the FASB issued ASU 2015-14, Revenue from Contracts with Customers: Deferral of Effective Date, which deferred the effective date of adoption of ASU 2014-09 to interim and annual reporting periods beginning after December 15, 2017. Early adoption is permitted but not before the original effective date of December 15, 2016. In April 2016, the FASB issued ASU 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing, which clarifies aspects of ASU 2014-09 pertaining to the identification of performance obligations and the licensing implementation guidance, while retaining the related principles for those areas. There are two adoption methods available for implementation of this guidance. Under one method, the guidance is applied retrospectively to contracts for each reporting period presented, subject to allowable practical expedients. Under the other method, the guidance is applied only to the most current period presented, recognizing the cumulative effect of the change as an adjustment to the beginning balance of retained earnings, and also requires additional disclosures comparing the results to the previous guidance. The Company is evaluating the impact of the new standard on its accounting policies, processes and systems. The Company has assigned internal resources, is in the process of engaging a third-party service provider and has a preliminary project plan to finalize the evaluation and complete the implementation. The Company has preliminarily identified potential impacts to the timing of revenue recognition and the amortization period of costs to obtain contracts. The Company’s decision on the adoption method will be based on various factors including the significance of the impact of the new standard on the Company’s financial results and system capabilities. The Company has not yet completed the evaluation of these impacts and the adoption method has not been determined.
Fair Value Measurement | The Company classifies inputs to measure fair value using a three-level hierarchy that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. The categorization of financial instruments within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The hierarchy is prioritized into three levels (with Level 3 being the lowest) and is defined as follows:
Level 1: | Pricing inputs are based on quoted market prices for identical assets or liabilities in active markets (e.g., NYSE or NASDAQ). Active markets are those in which transactions for the asset or liability occur in sufficient frequency and volume to provide pricing information on an ongoing basis.
Level 2: | Pricing inputs include benchmark yields, trade data, reported trades and broker dealer quotes, two-sided markets and industry and economic events, yield to maturity, Municipal Securities Rule Making Board reported trades and vendor trading platform data. Level 2 includes those financial instruments that are valued using various pricing services and broker pricing information including Electronic Communication Networks and broker feeds.
Level 3: | Pricing inputs include significant inputs that are generally less observable from objective sources, including the Company’s own assumptions.
The Company reviews the fair value hierarchy classification on a quarterly basis. Changes in the observability of valuation inputs may result in a reclassification of levels for certain securities within the fair value hierarchy.
