Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note 2. Summary of Significant Accounting Policies Basis of presentation The Company’s consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”). In the opinion of management, the financial statements as of December 31, 2018 and 2017 and for the years ended December 31, 2018, 2017 and 2016 include all adjustments (including normal recurring accruals) necessary for a fair presentation of the consolidated financial position, results of operations, comprehensive income and cash flows for the periods presented. The accompanying consolidated financial statements include the accounts of the Company, its wholly-owned and majority-owned subsidiaries and investments in variable interest entities in which the Company is determined to be the primary beneficiary. All significant intercompany accounts and transactions have been eliminated in consolidation. The portions of majority-owned subsidiaries that the Company does not own are reflected as noncontrolling interests on the consolidated balance sheet. Noncontrolling interests in companies are accounted for by the cost method where the Company does not exercise significant influence over the investee. Investments in entities over which the Company has the ability to exercise significant influence but does not have a controlling interest are accounted for under the equity method of accounting. The Company considers several factors in determining whether it has the ability to exercise significant influence with respect to investments, including, but not limited to, direct and indirect ownership level in the voting securities, active participation on the board of directors, approval of operating and budgeting decisions and other participatory and protective rights. Under the equity method, the Company’s proportionate share of the net income or loss of such investee is reflected in the Company’s consolidated results of operations. When the Company does not exercise significant influence over the investee, the investment is accounted for under the cost method. Although the Company owns interests in companies that it accounts for pursuant to the equity method, the investments in those entities had no carrying value as of December 31, 2018 and 2017. The Company has no guarantees or other funding obligations to those entities, and the Company had no equity in the earnings or losses of those investees for the years ended December 31, 2018, 2017 and 2016. Use of estimates The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the reported amounts of revenues and expenses at the date of the consolidated financial statements and during the reporting periods, and to disclose contingent assets and liabilities at the date of the consolidated financial statements. Actual results could differ from those estimates. The most significant estimates relate to recognition of revenue, allowances over accounts receivable, reserves over inventory balances, the recognition and measurement of assets acquired and liabilities assumed in business combinations at fair value, assessment of indicators of goodwill impairment, measurement of contingent considerations at fair value, determination of useful lives of the Company’s satellite network and other equipment and intangible assets, the assessment of expected cash flows used in evaluating long-lived assets, including intangible assets, for impairment, calculation of capitalized development costs, accounting for uncertainties in income tax positions, estimates associated with warranty costs and loss contingencies, estimates related to the recognition and subsequent valuation of contingent considerations and the value of securities underlying stock-based compensation. Business combinations The Company accounts for business combinations pursuant to Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 805 “Business Combinations”, which requires that assets acquired and liabilities assumed be recorded at their respective fair values on the date of acquisition. The fair value of the consideration paid is assigned to the underlying net assets of the acquired business based on their respective fair values. Any excess of the purchase price over the estimated fair values of the net assets acquired is allocated to goodwill. The purchase price allocation process requires the Company to make significant assumptions and estimates in determining the purchase price and the fair value of assets acquired and liabilities assumed at the acquisition date. The Company’s assumptions and estimates are subject to refinement and, 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 conclusion of the measurement period, any subsequent adjustments are recorded to the Company’s consolidated statements of operations. The Company’s consolidated financial statements and results of operations reflect an acquired business after the completion of the acquisition. Contingent consideration The Company determines the acquisition date fair value of contingent consideration obligations based on a probability-weighted income approach derived from milestone estimates and a probability assessment with respect to the likelihood of achieving performance metrics. The fair value measurement is based on significant inputs not observable in the market and thus represents a Level 3 measurement as defined in FASB ASC Topic 820 “Fair Value Measurement.” At each reporting date, the contingent consideration obligation will be revalued to estimated fair value and changes in fair value will be reflected as income or expense in the Company’s consolidated statement of operations. Changes in the fair value of the contingent consideration obligations may result from changes in probability assumptions with respect to the likelihood of achieving the various contingent payment obligations. Adverse changes in assumptions utilized in the Company’s contingent consideration fair value estimates could result in an increase in the Company’s contingent consideration obligation and a corresponding charge to operating income. Acquisition-related and integration costs Acquisition-related and integration costs include professional services expenses and identifiable integration costs directly attributable to acquisitions. For the years ended December 31, 2018, 2017 and 2016, the Company incurred acquisition-related and integration costs of $1,624, $3,315 and $1,630, respectively. These costs were expensed as incurred and are reflected in acquisition-related and integration costs on the Company’s consolidated statements of operations. Revenue recognition On January 1, 2018, the Company adopted FASB Accounting Standards Update (“ASU”) No. 2014-09 “Revenue from Contracts with Customers” (“ASU 2014-09”). The Company reviewed its contract portfolio and determined its application of ASU 2014-09 did not have a material impact on the comparability of revenue recognized prior to the adoption of ASU 2014-09. The Company derives recurring service revenues mostly from monthly fees for industrial IoT connectivity services that consist of subscriber-based and recurring monthly usage fees for each subscriber communicator or SIM activated for use on its satellite network, other satellite networks and cellular wireless networks that the Company resells to its resellers, Market Channel Partners (“MCPs”) and Market Channel Affiliates (“MCAs”), and direct customers. In addition, the Company earns service revenues from subscription-based services providing recurring AIS data services to government and commercial customers worldwide. The Company also earns recurring service revenues from activations of subscriber communicators and SIMs, optional separately priced extended warranty service agreements extending beyond the initial warranty period, typically one year, which are billed to the customer upon shipment of a subscriber communicator, and royalty fees relating to the manufacture of subscriber communicators under a manufacturing agreement. Service revenues derived from usage fees are generally based upon the data transmitted by a customer, the overall number of subscriber communicators and/or SIMs activated by each customer, and whether the Company provides services through its value-added portal. Using the output method, these service revenues are recognized over time, as services are rendered, or at a point in time, based on the contract terms. AIS service revenues are generated over time from monthly subscription-based services supplying AIS data to its customers and resellers using the output method. Revenues from the activation of both subscriber communicators and SIMs are initially recorded as deferred revenues and are, thereafter, recognized on a ratable basis using a time-based output method, generally over three years, the estimated life of the subscriber communicator. Revenues from separately priced extended warranty service agreements extending beyond the initial warranty period, typically one year, are initially recorded as deferred revenues and are, thereafter, recognized on a ratable basis using a time-based output method, generally over two to five years. Revenues generated from royalties relating to the manufacture of subscriber communicators by third parties are recognized at a point in time when the third party notifies the Company of the units it has manufactured and a unique serial number is assigned to each unit by the Company. The Company earns other service revenues from installation services and engineering, technical and management support services. Revenues generated from installation services are recognized at a point in time using the output method when the services are completed. Revenues generated from engineering, technical and management support services are recognized over time as the service is provided. The Company also generates other service revenues through the sale of software licenses to its customers, which is recognized at a point in time using the output method when the license is provided to the customer. Product sales are derived from sales of complete industrial IoT telematics devices, modems or cellular wireless SIMs (for the Company’s terrestrial-communication services) to the Company’s resellers (i.e., MCPs and MCAs) and direct customers. Product sales are recognized at a point in time when title transfers, when the products are shipped or when customers accept the products, depending on the specific contractual terms. Sales of subscriber communicators and SIMs are not subject to return and title and risk of loss pass to the customer generally at the time of shipment. Amounts received prior to the performance of services under customer contracts are recognized as deferred revenues and revenue recognition is deferred until such time that all revenue recognition criteria have been met. Deferred revenue as of December 31, 2018 and 2017 consisted of the following: December 31, 2018 2017 Service activation fees $ 2,813 $ 5,509 Prepaid services 7,816 2,754 Extended warranty revenues 796 459 11,425 8,722 Less current portion (5,954 ) (6,263 ) Long-term portion $ 5,471 $ 2,459 During the years ended December 31, 2018 and 2017, the Company recognized revenue of $5,236 and $6,114, respectively, which had been included as deferred revenue as of December 31, 2017 and 2016. Shipping costs billed to customers are included in product sales and the related costs are included as cost of product sales on the Company’s consolidated statements of operations. The Company generates revenue from leasing arrangements of subscriber communicators, under FASB ASC Topic 840 “Leases” (“ASC 840”), using the estimated selling prices for each of the deliverables recognized. Product and installation revenues associated with these arrangements are recognized upon shipment or installation of the subscriber communicator, depending on the specific contractual terms. Service and warranty revenues are recognized on an accrual basis, as services are rendered, or on a cash basis, if collection from the customer is not reasonably assured at the time the service is provided. The following table summarizes the components of revenue from contracts with customers, as well as revenue recognized under ASC 840: Year Ended December 31, 2018 2017 2016 Revenue from contracts with customers: Recurring service revenues $ 148,367 $ 126,540 $ 106,515 Other service revenues 5,222 8,398 6,366 Total service revenues 153,589 134,938 112,881 Product sales 117,018 112,942 73,863 Total revenue from contracts with customers 270,607 247,880 186,744 Product sales recognized under ASC 840 5,533 6,340 — Total revenues $ 276,140 $ 254,220 $ 186,744 Revenue recognition for arrangements with multiple performance obligations The Company enters into contracts with its customers that include multiple performance obligations, which typically include subscriber communicators, monthly usage fees and optional extended warranty service agreements. The Company evaluates each item to determine whether it represents a promise to transfer a distinct good or service to the customer and therefore is a separate performance obligation under ASU 2014-09. If a contract is separated into more than one performance obligation, the Company allocates the total transaction price to each performance obligation in an amount based on the estimated relative stand-alone selling prices of each performance obligation. The Company uses an observable price to determine the stand-alone selling price for separate performance obligations when sold on its own or a cost-plus margin approach when one is not available. If an arrangement provided to a customer has a significant and incremental discount on future revenue, such right is considered a performance obligation and a proportionate amount of the discount should be allocated to each element based on the relative stand-alone selling price of each element, regardless of the discount. The Company has determined that arrangements provided to its customers do not include significant and incremental discounts. The Company has elected not to disclose the value of unsatisfied performance obligations since these obligations would have an original expected length of one year or less. Costs of revenues The Company operates its own LEO satellite network and accompanying ground equipment, including fifteen gateway earth stations, three AIS data reception earth stations, and three regional gateway control centers. The Company’s proprietary satellite-based communications system is typically characterized by high initial capital expenditures and relatively low marginal costs for providing service. The Company resells network connectivity for two other satellite networks and seven terrestrial network partners. Reselling network connectivity typically involves a cost for each device connected to the network system and the amount paid to each provider will vary. Cost of services is comprised of expenses to operate the Company’s network, such as payroll and related costs, including stock-based compensation, installation costs, and usage fees to third-party networks. The Company mostly sells industrial IoT telematics devices and modems that the Company designs and builds with contract manufacturers. Cost of product sales includes the purchase price of subscriber communicators and SIMs sold, costs of warranty obligations, shipping charges, as well as operational costs of the Company’s employees and inventory management to fulfill customer orders. Foreign currency translation The Company has foreign operations where the functional currency is the local currency. For these operations, assets and liabilities are translated using end-of-period exchange rates and revenues, expenses and cash flows are translated using average rates of exchange for the period. Equity is translated at the rate of exchange at the date of the equity transaction. Translation adjustments are recognized in stockholders’ equity as a component of accumulated other comprehensive income (loss). Foreign currency transaction gains and losses related to assets and liabilities that are denominated in a currency other than the functional currency are included in other income (expense) on the consolidated statements of operations. Foreign currency translation gains and losses related to operational expenses denominated in a currency other than the functional currency are included in selling, general and administrative expenses (“SG&A”) on the consolidated statements of operations. For the years ended December 31, 2018, 2017 and 2016, the Company recorded a foreign currency translation loss of $76, $374, and $4, respectively. Fair value of financial instruments The Company has no financial assets or liabilities that are measured at fair value on a recurring basis. However, if certain triggering events occur, the Company is required to evaluate the non-financial assets for impairment and any resulting asset impairment would require that a non-financial asset be recorded at fair value. FASB ASC Topic 820 “Fair Value Measurement Disclosure,” prioritizes inputs used in measuring fair value into a hierarchy of three levels: Level 1- unadjusted quoted prices for identical assets or liabilities traded in active markets; Level 2- inputs other than quoted prices included within Level 1 that are either directly or indirectly observable; and Level 3- unobservable inputs in which little or no market activity exists, therefore requiring an entity to develop its own assumptions that market participants would use in pricing. The carrying amounts of the Company’s financial instruments, including cash, restricted cash, accounts receivable and accounts payable approximated their fair values due to the short-term nature of these items. The fair value of the Senior Secured Notes is based on observable relevant market information. Fluctuation between the carrying amount and the fair value of the Senior Secured Notes for the period presented is associated with changes in market interest rates. The Company may redeem all or part of the Senior Secured Notes at any time or from time to time at its option at specified redemption prices that would include “make-whole” premiums. Refer to “Note 10 – Notes Payable” for more information. The carrying amounts and fair values of the Company’s Senior Secured Notes are shown in the following table: December 31, 2018 December 31, 2017 Carrying Amount Fair Value Carrying Amount Fair Value Senior Secured Notes $ 250,000 $ 255,000 $ 250,000 $ 266,550 The fair value of the note payable-related party, $1,298 book value, has a de minimis value. Cash and cash equivalents The Company considers all liquid investments with original maturities of three months or less, at the time of purchase, to be cash equivalents. At December 31, 2018 and 2017, the Company had a cash balance of $53,766 and $34,830, respectively. Concentration of risk The Company’s customers are primarily commercial organizations. Accounts receivable are generally unsecured. Accounts receivable are due in accordance with payment terms included in contracts negotiated with customers. Amounts due from customers are stated net of an allowance for doubtful accounts. The Company determines its allowance for doubtful accounts by considering a number of factors, including the length of time accounts are past due, the customer’s current ability to pay its obligations to the Company and the condition of the general economy and the industry as a whole. The Company writes off accounts receivable when they are deemed uncollectible. There were no customers with revenues greater than 10% of the Company’s consolidated total revenues for the years ended December 31, 2018 and 2016. For the year ended December 31, 2017, JB Hunt Transport Services, Inc. comprised 10.8% of the Company’s consolidated total revenues. There were no customers with accounts receivable greater than 10% of the Company’s consolidated accounts receivable as of December 31, 2018 and 2017. As of December 31, 2018, the Company did not maintain in-orbit insurance coverage for its ORBCOMM Generation 1 (“OG1”) or ORBCOMM Generation 2 (“OG2”) satellites to address the risk of potential systemic anomalies, failures or catastrophic events affecting its satellite constellation. Inventories Inventories are stated at the lower of cost or net realizable value, determined on a weighted average cost basis. At December 31, 2018 and 2017, inventory, net of inventory obsolescence, consisted primarily of finished goods and purchased parts to be utilized by its contract manufacturer totaling $27,701 and $34,465, respectively, and raw materials totaling $6,599 and $7,972, respectively. The Company reviews inventory quantities on hand, evaluates the realizability of inventories and adjusts the carrying value as necessary based on forecasted product demand. A provision, recorded in cost of product sales on the Company’s consolidated statements of operations, is made for potential losses on slow-moving and obsolete inventories, when identified. Satellite network and other equipment, net Satellite network and other equipment, net are stated at cost less accumulated depreciation and amortization. Major renewals and improvements are capitalized, while maintenance and repairs are charged to operations as incurred. Depreciation and amortization are recognized using the straight-line method over the estimated useful lives of the assets. Leasehold improvements are amortized over the shorter of their useful life or their respective lease term. The following table provides the range of estimated useful lives used for each asset type: Useful Life (years) Satellite network 10 Capitalized software 3-7 Computer hardware 3 Other 2-7 Satellite network includes costs of the constellation of satellites, and the ground and control facilities, consisting of gateway earth stations, gateway control centers and the network control center. As of December 31, 2018 and 2017, assets under construction primarily consist of costs associated with acquiring, developing and testing software and hardware for internal and external use that have not yet been placed into service. The Company capitalized interest on its Initial Term Loan Facility, as defined below, during the construction period of its satellites and began depreciating these costs upon the satellites being placed into service. Capitalized interest was added to the cost of the satellites prior to being placed in service. The Company capitalized interest and deferred issuance costs associated with these facilities through March 1, 2016, the date the final 11 OG2 satellites were placed in service. For the year ended December 31, 2016, interest capitalized was $744. Valuation of long-lived assets Property and equipment and other long-lived assets are tested for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. The Company measures recoverability by comparing the carrying amount to the projected undiscounted cash flows the assets are expected to generate. An impairment loss is recognized to the extent the carrying value exceeds the fair value. The Company’s satellite constellation and related assets are evaluated as a single asset group whenever facts or circumstances indicate that the carrying value may not be recoverable. If indicators of impairment are identified, recoverability of long-lived assets is measured by comparing their carrying amount to the projected cash flows the assets are expected to generate. Determining whether an impairment has occurred typically requires the use of significant estimates and assumptions, including the allocation of cash flows to assets or asset groups and, if required, an estimate of fair value for those assets or asset groups. If a satellite were to fail while in orbit, the resulting loss would be charged to expense in the period it is determined that the satellite is not recoverable. The amount of any such loss would be reduced to the extent of insurance proceeds estimated to be received. During the years ended December 31, 2017 and 2016, an impairment loss of $31,224 and $10,680 was recorded, respectively, to write off the net book value relating to the Company’s in-orbit OG2 satellites. In addition, an impairment loss of $466 to write off the net book value related to one of the Company’s leased AIS satellites was recorded in the year ended December 31, 2016. There was no impairment loss recorded for the year ended December 31, 2018. See “Note 6 – Satellite Network and Other Equipment, Net” for additional details relating to the impairment of these satellites. Capitalized development costs for internal use The Company capitalizes the costs of acquiring, developing and testing software to meet the Company’s internal needs. Capitalization of costs associated with software obtained or developed for internal use commences when both the preliminary project stage is completed and management has authorized further funding for the project, based on a determination that it is probable that the project will be completed and used to perform the function intended. Capitalized costs include only (1) external direct cost of materials and services consumed in developing or obtaining internal-use software, and (2) payroll and payroll-related costs for employees who are directly associated with and devote time to the internal-use software project. Capitalization of such costs ceases no later than the point at which the project is substantially complete and ready for its intended use. Internal-use software costs are amortized once the software is placed in service using the straight-line method over periods ranging from three to seven years. Capitalized development costs for external use The Company capitalizes certain software development costs upon the establishment of technological feasibility. Technological feasibility is considered to have occurred upon completion of either a detail program design or a working model. Software development costs will be amortized over the estimated life of the product once it is has been released for commercial sale. Capitalized patent defense costs The Company capitalizes costs incurred in connection with the defense of a patent the Company owns when the defense against the alleged infringer is deemed probable of success, and the costs will increase the value of the patent. Goodwill Goodwill represents the excess of the purchase price over the underlying net tangible and intangible assets of the Company’s acquisitions. Goodwill is not amortized, but is tested for impairment on an annual basis and between annual tests whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. Goodwill is tested at the reporting unit level, which is defined as an operating segment or one level below the operating segment. The Company operates in one reportable segment which is its only reporting unit. The Company tests for an indication of goodwill impairment annually on November 30 or when an indicator of impairment exists, by comparing the fair value of the reporting unit to its carrying value. If there is an indication of impairment, the Company performs a “step two” test to measure the impairment. There was no impairment of goodwill for the years ended December 31, 2018, 2017 and 2016. Intangible assets Intangible assets that are not considered to have an indefinite life are amortized over their useful lives. Intangible assets include patents and technology, customer lists and trademarks. Intangible assets are amortized using the straight line method over the estimated useful lives of the assets. Impairment of long-lived assets The Company reviews its long-lived assets and amortizable intangible assets whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. In connection with this review, the Company also re-evaluates the periods of depreciation and amortization for these assets. The Company recognizes an impairment loss when the sum of the future undiscounted net cash flows expected to be realized from the asset is less than its carrying amount. If an asset is considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the asset exceeds its fair value, which is determined using the projected discounted future net cash flows, using the appropriate discount rate. Warranty costs The Company accrues for warranty coverage on product sales estimated at the time of sale based on historical costs to repair or replace products for customers compared to historical product sales. The warranty accrual is included in accrued liabilities on the Company’s consolidated balance sheets. Separately-priced extended warranty coverage is recorded as warranty revenue over the term of the extended warranty coverage and the related warranty costs are recorded as incurred during the coverage period. Warranty coverage that includes additional services, such as repairs and maintenance of the product, is treated as a separate performance obligation and the related warranty and repairs/maintenance costs are recorded as incurred. Income taxes The Company estimates its income taxes separately for each tax jurisdiction in which it conducts operations. This process involves estimating actual current tax expense and assessing temporary differences resulting from different treatment of items between book and tax which results in deferred tax assets and liabilities. The Company recognizes a change in income in tax rates on deferred tax assets and liabilities in the period that includes the enactment date. Valuation allowances are established when realization of deferred tax assets is not considered more likely than not. The Company recognizes the effect of tax law changes in the period of enactment. Changes in existing tax laws and rates, their related interpretations, and the uncertainty generated by the current economic environment may affect the amounts of the Company’s deferred tax liabilities or the valuations of the Company’s deferred tax assets over time. The Company’s accounting for deferred tax consequences represents management’s best estimate of future events that can be appropriately reflected in the accounting estimates. In determining whether the realization of deferred tax assets is considered to be more likely than not, the Company assesses the realizability of the deferred tax assets on a jurisdiction by jurisdiction basis. This assessment is dependent upon past operating results and projected profitability. The weight given to the positive and negative evidence is commensurate with the extent to which the evidence is objectively verified. The Company accounts for uncertainty in income tax positions using a two-step approach. The first step is to determine whether it is more likely than not that a tax position will be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position. The second step is to measure the tax position at the largest amount of benefit that is greater than 50% likely of being realized upon ultimate settlement. The Company recognizes interest and penalties related to uncertain tax positions in income tax expense. Loss contingencies The Company accrues for costs relating to litigation, claims and other contingent matters when such liabilities become probable and reasonably estimable. Such estimates may be based on advice from third parties or on management’s judgment, as appropriate. Actual amounts paid may differ from amounts estimated, and such differences will be charged to operations in the period in which the final determination of the liability is made. Pre-acquisition contingencies The Company has evaluated pre-acquisition contingencies that existed as of the acquisition dates of the businesses acquired. If any pre-acquisition contingencies acquired as part of an acquisition become probable and estimable, the Company will record such amounts at fair market value in the measurement period or the Company’s results of operations after the measurement period, as applicable.

Acquisitions	Note 3. Acquisitions 2017 Business Development Blue Tree Systems Limited On October 2, 2017, pursuant to a Share Purchase Agreement entered into by ORBCOMM Technology Ireland Limited, a wholly owned subsidiary of the Company, and Blue Tree Systems Investment Limited, Investec Ventures Ireland Limited and certain individual sellers (collectively, the “Sellers”), the Company completed the acquisition of 100% of the outstanding shares of Blue Tree Systems Limited, for an aggregate consideration of (i) $34,331 in cash; (ii) issuance of 191,022 shares of the Company’s common stock, valued at $10.47 per share, which reflected the Company’s common stock closing price one business day prior to the closing date; and (iii) additional consideration up to $5,750 based on Blue Tree Systems Limited achieving certain operational objections (the “Blue Tree Acquisition”). Purchase Price Allocation The Blue Tree Acquisition has been accounted for using the acquisition method of accounting. This method requires that assets acquired and liabilities assumed in a business combination be recognized at their fair values as of the acquisition date (the “Acquisition Method”). The excess of the preliminary purchase price over the preliminary net assets was recorded as goodwill. The preliminary allocation of the purchase price was based upon a preliminary valuation and the estimates and assumptions are subject to change during the one-year measurement period. The total consideration for the Blue Tree Acquisition was $37,107, of which $776 represents acquisition date contingent consideration at fair value, in a debt-free, cash-free transaction. During the year ended December 31, 2018, the Company recorded a measurement period adjustment related to certain working capital accounts, resulting in a decrease in goodwill of $393. The purchase price allocation for the acquisition is as follows: Amount Cash $ 656 Accounts receivable 2,335 Inventories 1,395 Prepaid expenses and other current assets 992 Property, plant and equipment 72 Intangible assets 12,020 Total identifiable assets acquired 17,470 Accounts payable 4,124 Accrued expenses 778 Deferred tax liability 1,503 Total liabilities assumed 6,405 Net identifiable assets acquired 11,065 Goodwill 26,042 Total purchase price $ 37,107 Intangible Assets The estimated fair value of the technology and trademark intangible assets was determined using the “relief from royalty method” under the income approach, which is a valuation technique that provides an estimate of the fair value of an asset based on the costs savings that are available through ownership of the asset by the avoidance of paying royalties to license the use of the assets from another owner (the “Technology and Trademark Valuation Technique”). The estimated fair value of the customer lists was determined using the “excess earnings method” under the income approach, which represents the total income to be generated by the asset (the “Customer List Valuation Technique”). Some of the more significant assumptions inherent in the development of those asset valuations include the projected revenue associated with the asset, the appropriate discount rate to select in order to measure the risk inherent in each future cash flow stream, the assessment of each asset’s life cycle, as well as other factors. The discount rate used to arrive at the present value at the acquisition date of the customer lists and technology was 26.5%. The remaining useful lives of the technology and trademarks were based on historical product development cycles, the projected rate of technology migration and a market participant’s use of these intangible assets and the pattern of projected economic benefit of these intangible assets. The remaining useful lives of customer lists were based on the customer attrition and the projected economic benefit of these customers. Estimated Useful Life (years) Amount Customer lists 10 $ 9,200 Technology 10 2,700 Tradename 1 120 $ 12,020 Goodwill The Blue Tree Acquisition solidified the Company’s transportation offering of fleet management and driver safety solutions to enterprises and industrial companies around the world that operate large commercial vehicle fleets. These factors contributed to a preliminary estimated purchase price resulting in the recognition of goodwill. The goodwill attributable to the Blue Tree Acquisition is not deductible for tax purposes. Indemnification Asset In connection with the Share Purchase Agreement, the Company entered into an escrow agreement with the Sellers and an escrow agent. Under the terms of this escrow agreement, $3,675 was placed in an escrow account through April 2019 to fund any indemnification obligations to the Company under the Share Purchase Agreement. Under the terms of the escrow agreement, as of any release date for any portion of the escrow account amount, the value of any then submitted and unresolved indemnification claims will be retained in the escrow account until such time as the applicable claims are resolved. Contingent Consideration Additional consideration is conditionally due to the Sellers upon achievement of certain financial milestones through December 2018. The fair value measurement of the contingent consideration obligation is determined using Level 3 unobservable inputs supported by little or no market activity based on the Company’s own assumptions. The estimated fair value of the contingent consideration was determined based on the Company’s preliminary estimates using the probability-weighted discounted cash flow approach. The financial milestone for this contingent consideration has not been met, and therefore, the Company recorded a reduction of the contingent liability of $776 in selling, general and administrative (“SG&A”) expenses on the consolidated statement of operations for the year ended December 31, 2018. inthinc Technology Solutions, Inc. On June 9, 2017, pursuant to the asset purchase agreement (the “Asset Purchase Agreement”) entered into by the Company and, inthinc, Inc., inthinc Technology Solutions, Inc., tiwi, Inc., inthinc Telematics, Inc., DriveAware, Inc., inthinc Chile, SP, and inthinc Investors, L.P. (collectively, “Inthinc”), the Company completed the acquisition of Inthinc for an aggregate consideration of (i) $34,236 in cash, on a debt-free, cash-free basis; (ii) issuance of 76,796 shares of the Company’s common stock, valued at $9.95 per share, which reflected a 20 trading day average price of the Company’s stock ending June 8, 2017; and (iii) additional contingent consideration of up to $25,000 subject to certain operational milestones, payable in stock or a combination of cash and stock at the Company’s election (the “Inthinc Acquisition”). Purchase Price Allocation The Inthinc Acquisition has been accounted for using the Acquisition Method. The excess of the purchase price over the preliminary net assets was recorded as goodwill. The preliminary allocation of the purchase price was based upon a preliminary valuation and the estimates and assumptions are subject to change during the one-year measurement period. During the year ended December 31, 2018, the Company recorded a measurement period adjustment related to certain working capital accounts, resulting in a decrease in goodwill of $156. The total consideration for the Inthinc Acquisition was $44,835, of which $9,835 represents acquisition date contingent consideration at fair value, in a debt-free, cash-free transaction. The purchase price allocation for the acquisition is as follows: Amount Accounts receivable $ 2,652 Inventories 906 Prepaid expenses and other current assets 112 Property, plant and equipment 258 Lease receivable 5,067 Intangible assets 16,000 Total identifiable assets acquired 24,995 Accounts payable 4,613 Accrued expenses 275 Other current and non-current liabilities 1,326 Total liabilities assumed 6,214 Net identifiable assets acquired 18,781 Goodwill 26,054 Total purchase price $ 44,835 Intangible Assets The estimated fair value of the technology intangible assets was determined using the “relief from royalty method” under the income approach, which is a valuation technique that provides an estimate of the fair value of an asset based on the costs savings that are available through ownership of the asset by the avoidance of paying royalties to license the use of the assets from another owner. The estimated fair value of the customer lists was determined using the Customer List Valuation Technique. Some of the more significant assumptions inherent in the development of those asset valuations include the projected revenue associated with the assets, the appropriate discount rate to select in order to measure the risk inherent in each future cash flow stream, the assessment of each asset’s life cycle, as well as other factors. The discount rate used to arrive at the acquisition date present value of the customer lists and technology was 12%. The remaining useful lives of the technology were based on historical product development cycles, the projected rate of technology migration and a market participant’s use of these intangible assets and the pattern of projected economic benefit of these intangible assets. The remaining useful lives of the customer lists were based on the customer attrition and projected economic benefit of these customers. Estimated Useful Life (years) Amount Customer lists 15 $ 12,400 Technology 10 3,600 $ 16,000 Goodwill The Inthinc Acquisition allows the Company to offer fleet management and driver safety solutions to enterprises and industrial companies around the world that operate large commercial vehicle fleets. These factors contributed to a preliminary estimated purchase price resulting in the recognition of goodwill. The goodwill attributable to the Inthinc Acquisition is deductible for tax purposes. Indemnification Asset In connection with the Asset Purchase Agreement, the Company entered into an escrow agreement with Inthinc and an escrow agent. Under the terms of this escrow agreement, $1,000 was placed in an escrow account through September 9, 2019 to fund any working capital and indemnification obligations to the Company under the Asset Purchase Agreement. Under the terms of the escrow agreement, as of any release date for any portion of the escrow account amount, the value of any then submitted and unresolved indemnification claims will be retained in the escrow account until such time as the applicable claims are resolved. In the year ended December 31, 2018, the Company received $1,000 from the escrow account to partially fund the working capital adjustment payment and indemnification obligations due to the Company and recorded a credit to SG&A expenses in the year ended December 31, 2018. Acquired Customer Product Obligation As a result of the Inthinc Acquisition, the Company acquired customer product obligations on Inthinc’s product sales. The Company’s analysis of the customer product obligation is estimated based on Inthinc’s historical costs to replace or fix products for customers, as well as installations costs associated with these obligations. As the Company continues to gather additional information, these accrual estimates may differ from actual results and adjustments to the estimated customer product liability would be required. The Company continues to evaluate customer product obligation relating to the Inthinc Acquisition throughout the measurement period. If the Company determines that adjustments to this amount is required during the remainder of the measurement period, such amount will be recorded as an adjustment to goodwill. On June 9, 2017, the Company had estimated additional product obligations of $1,032 relating to customer product obligations it was investigating associated with the Inthinc Acquisition as a result of undisclosed commitments made by Inthinc prior to the Company’s acquisition of Inthinc. As of December 31, 2018, the Company had a remaining liability of $546 in accrued liabilities on the Consolidated Balance Sheet in connection with this acquired product liability obligation. Contingent Consideration Additional consideration is conditionally due to the Inthinc sellers upon achievement of certain financial milestones through June 2019. The fair value measurement of the contingent consideration obligation is determined using Level 3 unobservable inputs supported by little or no market activity based on the Company’s own assumptions. The estimated fair value of the contingent consideration was determined based on the Company’s preliminary estimates using the probability-weighted discounted cash flow approach. As of December 31, 2018, the Company recorded $2,063 in accrued expenses on the consolidated balance sheet in connection with the contingent consideration. As of December 31, 2017, the Company recorded $9,313 in other non-current liabilities on the consolidated balance sheet in connection with the contingent consideration. Three financial milestones for this additional consideration are not expected to be met and the fourth financial milestone is estimated to be met at a lower than previously estimated level. Therefore, the Company recorded a reduction of the contingent liability of $7,250 and $795 in SG&A expenses on the consolidated statement of operations for the years ended December 31, 2018 and 2017, respectively. For the year ended December 31, 2017, charges of $274 were recorded in SG&A expenses for accretion associated with the contingent consideration. 2016 Business Development Skygistics Ltd. On May 26, 2016, pursuant to an Asset Purchase Agreement entered into on April 11, 2016 among a wholly owned subsidiary of the Company, Skygistics Propriety Limited and Satconnect Propriety Limited (the “Skygistics Sellers”), the Company completed the acquisition of substantially all of the assets of Skygistics (PTY) Ltd. (“Skygistics”), for a purchase price of $3,835 and additional contingent consideration of up to $954, subject to certain operational milestones (the “Skygistics Acquisition”). Purchase Price Allocation The Skygistics Acquisition has been accounted for using the Acquisition Method. The excess of the purchase price over the net assets was recorded as goodwill. The total consideration for the Skygistics Acquisition was $4,349, of which $514 represents acquisition date contingent consideration at fair value, in a debt-free, cash-free transaction. The purchase price allocation for the Skygistics Acquisition is as follows: Amount Cash and cash equivalents $ 383 Accounts receivable 939 Inventories 292 Other current assets 112 Property, plant and equipment 418 Deferred tax assets 105 Intangible assets 1,545 Total identifiable assets acquired 3,794 Accounts payable and accrued expenses 410 Deferred tax liabilities 433 Other liabilities 11 Total liabilities assumed 854 Net identifiable assets acquired 2,940 Goodwill 1,409 Total preliminary purchase price $ 4,349 Intangible Assets The estimated fair value of the customer lists was determined using the Customer List Valuation Technique. The discount rate used to arrive at the acquisition date present value of the customer lists was 19%. The remaining useful lives of customer lists were based on the customer attrition and projected economic benefit of these customers. The Company recorded a customer list intangible asset in the amount of $1,545 and assigned an estimated useful life of 13 years to the customer list intangible asset. Goodwill The Skygistics Acquisition provides a broad range of satellite and cellular connectivity options, as well as telematics solutions centered on the management of remote and mobile assets to more than 250 telematics and enterprise customers. These factors contributed to a preliminary estimated purchase price resulting in recognition of goodwill. The goodwill attributable to the Skygistics Acquisition is not deductible for tax purposes. Indemnification Asset In connection with the Asset Purchase Agreement, the Company entered into an escrow agreement with the Skygistics Sellers and an escrow agent. Under the terms of the escrow agreement, $757 was placed in an escrow account through August 2017 to fund any indemnification obligations owed to the Company under the Asset Purchase Agreement. In November 2016, half of the escrow amount was released from the escrow fund to the Skygistics Sellers and, in August 2017, the remainder was released to the Skygistics Sellers, in accordance with the terms of the escrow agreement. Contingent Consideration Additional consideration is conditionally due to the Skygistics Sellers upon achievement of certain financial milestones through April 2017. The fair value measurement of the contingent consideration obligation is determined using Level 3 unobservable inputs supported by little or no market activity based on the Company’s own assumptions. The estimated fair value of the contingent consideration was determined based on the Company’s preliminary estimates using the probability-weighted discounted cash flow approach. The financial milestone for this additional consideration has not been met, and therefore, the Company recorded a reduction of the contingent liability of $519 in SG&A expenses on the consolidated statement of operations for the year ended December 31, 2017.

For the years ended December 31, 2018, 2017 and 2016, the Company capitalized stock-based compensation of $503, $453, and $316, respectively. The Company has not recognized, and currently does not expect to recognize in the foreseeable future, any tax benefit related to stock-based compensation as a result of the full valuation allowance on its net deferred tax assets and its net operating loss carryforwards generated in the U.S. The following table summarizes the components of stock-based compensation expense in the Consolidated Statements of Operations for the years ended December 31, 2018, 2017 and 2016: Years Ended December 31, 2018 2017 2016 Cost of services $ 666 $ 525 $ 559 Cost of product sales 162 78 44 Selling, general and administrative 6,065 4,706 4,082 Product development 1,017 364 338 Total $ 7,910 $ 5,673 $ 5,023 As of December 31, 2018, the Company had unrecognized compensation costs for all share-based payment arrangements totaling $10,734.

As of December 31, 2018, $182 of total unrecognized compensation cost related to the time-based SARs is expected to be recognized through December 2019. The weighted-average grant date fair value of the time-based SARs granted in 2017 was $4.85 and per share, respectively. There were no time-based SARs granted during the year ended December 31, 2018 and 2016. The intrinsic value of the time-based SARs exercised during the year ended December 31, 2018 was $1,833.

As of December 31, 2018, no unrecognized compensation cost related to the performance-based SARs is expected to be recognized. There were no performance-based SARs granted during the years ended December 31, 2018, 2017 and 2016. The intrinsic value of the performance-based SARs exercised during the year ended December 31, 2018 was $1,390. The fair value of each time-based and performance-based SAR award is estimated on the date of grant using the Black-Scholes option pricing model with the assumptions described below. For the period indicated, the expected volatility was based on the Company’s historical volatility over the expected terms of the SAR awards. Estimated forfeitures were based on voluntary and involuntary termination behavior, as well as an analysis of actual forfeitures. The risk-free interest rate was based on the U.S. Treasury yield curve at the time of the grant over the expected term of the SAR grants. The Company did not grant time-based or performance-based SARs during the years ended December 31, 2018 and 2016. Year Ended December 31, 2018 2017 2016 Risk-free interest rate None 2.10% None Expected life (years) None 6.0 None Estimated volatility factor None 59.85% None Expected dividends None None None Time-Based Restricted Stock Units A summary of the Company’s time-based Restricted Stock Units (“RSUs”) for the year ended December 31, 2018 is as follows: Shares Weighted-Average Grant Date Fair Value Balance at January 1, 2018 818,480 $ 9.95 Granted 606,249 9.44 Vested (432,189 ) 9.32 Forfeited or expired (72,516 ) 10.46 Balance at December 31, 2018 920,024 $ 9.60 For the years ended December 31, 2018, 2017 and 2016, the Company recorded stock-based compensation expense of $4,627, $3,084 and $2,495 related to these time-based RSUs, respectively. As of December 31, 2018, $6,449 of total unrecognized compensation cost related to the time-based RSUs is expected to be recognized through June 2022. Performance-Based Restricted Stock Units A summary of the Company’s performance-based RSUs for the year ended December 31, 2018 is as follows: Shares Weighted-Average Grant Date Fair Value Balance at January 1, 2018 444,734 $ 9.48 Granted 387,748 9.15 Vested (168,068 ) 9.16 Forfeited or expired (50,809 ) 9.41 Balance at December 31, 2018 613,605 $ 9.44 For the years ended December 31, 2018, 2017 and 2016, the Company recorded stock-based compensation expense of $2,478, The fair value of the time-based and performance-based RSU awards are based upon the closing stock price of the Company’s common stock on the date of grant. Market Performance Units The Company grants Market Performance Units (“MPUs”) to its senior executives based on stock price performance over a three-year period measured on December 31 of each year in the performance period. The MPUs will vest in equal installments at the end of each year in the performance period only if the Company satisfies the stock price performance targets and the senior executives continue employment through the dates the Compensation Committee has determined that the targets have been achieved. As of December 31, 2018, the Compensation Committee determined that the fiscal year 2018 stock price performance targets were partially achieved for the 2018, 2017 and 2016 MPUs. As the MPUs contain both performance and service conditions, they have been treated as a series of three separate awards, or tranches, for purposes of recognizing stock-based compensation expense. The Company recognizes stock-based compensation expense on a tranche-by-tranche basis over the requisite service period for that specific tranche. The Company estimated the fair value of the MPUs using a Monte Carlo simulation model based on the following assumptions: Years Ended December 31, 2018 2017 2016 Risk-free interest rate 2.46% to 2.63% 1.76% to 1.98% 0.85% to 1.47% Estimated volatility factor 29.0% 27.0% 33.0% Expected dividends None None None For the years ended December 31, 2018, 2017 and 2016, the Company recorded stock-based compensation of $346, $862 and $781 relating to these MPUs, respectively. As of December 31, 2018, the Company recorded $527 and $131 in accrued liabilities and other non-current liabilities related to the MPUs, respectively, on the Consolidated Balance Sheet. As of December 31, 2017, the Company recorded $895 and $301 in accrued liabilities and other non-current liabilities related to the MPUs, respectively, on the Consolidated Balance Sheet. In January 2018, the Company issued 81,277 shares of common stock as a form of payment in connection with MPUs for achieving the fiscal year 2017 stock performance targets for the 2017, 2016 and 2015 MPUs. Employee Stock Purchase Plan On February 16, 2016, the Company’s board of directors adopted the ORBCOMM Inc. Employee Stock Purchase Plan (“ESPP”), which was approved by the Company’s shareholders on April 20, 2016. Under the terms of the ESPP, 5,000,000 shares of the Company’s common stock are available for issuance and eligible employees may have up to 10% of their gross pay deducted from their payroll, up to a maximum of $25 per year, to purchase shares of ORBCOMM common stock at a discount of up to 15% of its fair market value, subject to certain conditions and limitations. For the years ended December 31, 2018, 2017 and 2016, the Company recorded stock-based compensation expense of $272, $183 and $88, respectively, relating to the ESPP. For the year ended December 31, 2018, 71,440 shares and 81,525 shares of the Company’s common stock were purchased under the ESPP at a price of $8.06 and $8.21 per share, respectively.

The Senior Secured Notes were issued pursuant to an indenture, dated as of April 10, 2017, among the Company, certain of its domestic subsidiaries party thereto (the “Guarantors”) and U.S. Bank National Association, as trustee and collateral agent (the “Indenture”). The Senior Secured Notes are unconditionally guaranteed on a senior secured basis by the Guarantors, and are secured on a first priority basis by (i) pledges of capital stock of certain of the Company’s directly and indirectly owned subsidiaries; and (ii) substantially all of the other property and assets of the Company and the Guarantors, to the extent a first priority security interest is able to be granted or perfected therein, and subject, in all cases, to certain specified exceptions, and an intercreditor agreement with the collateral agent for the Company’s revolving credit facility described below The Company has the option to redeem some or all of the Senior Secured Notes at any time on or after April 1, 2020, at redemption prices set forth in the Indenture plus accrued and unpaid interest, if any, to the date of redemption. The Company also has the option to redeem some or all of the Senior Secured Notes at any time before April 1, 2020 at a redemption price of 100% of the principal amount of the Senior Secured Notes to be redeemed, plus a “make-whole” premium and accrued and unpaid interest, if any, to the date of redemption. In addition, at any time before April 1, 2020, the Company may redeem up to 35% of the aggregate principal amount of the Senior Secured Notes to be redeemed, plus accrued and unpaid interest, if any, to the date of redemption, with the proceeds from certain equity issuances.

The Secured Credit Facilities had a maturity of five years after the initial fund date of the Initial Term Loan Facility and were subject to mandatory prepayments in certain circumstances. The Secured Credit Facilities bore interest, at the Company’s election, of a per annum rate equal to either (a) a base rate plus 3.75% or (b) LIBOR plus 4.75%, with a LIBOR floor of 1.00%.

The U.S. Tax Cuts and Jobs Act of 2017 (the “2017 Tax Act”) The key impacts of the 2017 Tax Act on the Company’s financial statements were the re-measurement of deferred tax balances to the new corporate tax rate and the calculation of any impacts of the transition tax. The re-measurement of the deferred tax balances to the new corporate rate is complete and those amounts are not provisional. Although the Company has taxable earnings and profits from its foreign subsidiaries, the Company had no cash tax payments for the transition tax. The amount of taxable foreign earnings and profits was significantly less than the Company’s expected tax losses for 2017, therefore, the Company utilized these losses to offset the income inclusion regarding the transition tax. The Company has determined that it will elect an accounting policy to treat tax on global intangible low-taxed income inclusions under the 2017 Tax Act as a period cost when incurred. As part of the Company’s accounting for the acquisitions, a portion of the purchase price was allocated to goodwill. The acquired goodwill is deductible for tax purposes and amortized over fifteen years for income tax purposes. Under GAAP, the acquired goodwill is not amortized in the Company’s financial statements. As such, a deferred income tax expense and a deferred tax liability arise as a result of the tax deductibility for this amount for tax purposes but not for financial statement purposes. The resulting deferred tax liability, which is expected to continue to increase over time, will remain on the Company’s balance sheet indefinitely unless there is an impairment of the asset. As a result of the 2017 Tax Act and the changes it made to net operating loss carry forward rules, the Company is now able to use the above deferred tax liability as a source of future taxable income in evaluating the need for a valuation allowance. This change resulted in a deferred tax benefit of $1,693 during the year ended December 31, 2017. As of December 31, 2018 and 2017, the Company maintained a valuation allowance against all of its net deferred tax assets, excluding goodwill, attributable to operations in the United States as the realization was not considered more likely than not. The net change in the total valuation allowance for the years ended December 31, 2018, 2017 and 2016 was $6,124, $6,458 and $12,350, respectively. On January 1, 2017, the company adopted ASU 2016-09. Prior to adopting the ASU, the Company recognized tax benefits associated with the exercise of SARs and stock options and vesting of RSUs directly to stockholders’ equity only when the tax benefit reduces income tax payable on the basis that a cash tax savings has occurred. As a result of adopting this ASU the Company recognized the benefit of net operating loss carryovers that were created as a result of previous windfall tax deductions. The gross amount of windfall deductions that were previously not recognized was approximately $6,529. Due to a full valuation allowance, the recognition of the benefit for the windfall deductions did not have any impact to the consolidated balance sheet or consolidated statement of operations. As of December 31, 2018 and 2017, the Company had potentially utilizable federal net operating loss tax carryforwards of $108,746 The utilization of the Company’s net operating losses may be subject to a substantial limitation due to the “change of ownership provisions” under Section 382 of the Internal Revenue Code and similar state provisions. Such limitation may result in the expiration of the net operating loss carryforwards before their utilization. As of December 31, 2018, the Company has not provided deferred income taxes on the undistributed earnings of its foreign subsidiaries. The amount of such earnings was $21,603. These earnings have been permanently reinvested and the Company does not plan to initiate action that would precipitate the payment of income taxes thereon. It is not practicable to estimate the amount of additional tax that might be payable on these undistributed earnings. The following table is a reconciliation of the beginning and ending amount of unrecognized tax benefits: 2018 2017 2016 Balance at January 1, $ 856 $ 856 $ 775 Additions for tax positions related to prior years 398 — 81 Additions for tax positions related to current year — — — Reductions for tax positions of prior years (52 ) — — Settlements — — — Balance at December 31, $ 1,202 $ 856 $ 856 No interest and penalties related to unrecognized tax benefits were accrued during the years ended December 31, 2018 and 2017. The Company accrued interest and penalties related to uncertain tax positions of $43 for the year ended December 31, 2016. Interest and penalties are not reflected in the table above and are included in income tax expense. As of December 31, 2018, $1,121 of the unrecognized tax benefits have been recorded as a reduction to the Company’s federal and state net operating loss tax carryforwards in deferred tax assets. Due to the existence of the Company’s valuation allowance, $775 of these unrecognized tax benefits, if recognized, would not impact the Company’s effective income tax rate. The remaining balance of $427, if recognized, would affect the effective tax rate. The Company is subject to U.S. federal and state examinations by tax authorities from 2015 and 2014, respectively. The Company is also subject to examinations in its material non-U.S. jurisdictions for 2013 and later years.

Commitments and Contingencies	Note 14. Commitments and Contingencies Airtime credits In 2001, in connection with the organization of ORBCOMM Europe and the reorganization of the ORBCOMM business in Europe, the Company agreed to grant certain country representatives in Europe approximately $3,736 in airtime credits. The Company has not recorded the airtime credits as a liability for the following reasons: (i) the Company has no obligation to pay the unused airtime credits if they are not utilized; and (ii) the airtime credits are earned by the country representatives only when the Company generates revenue from the country representatives. The airtime credits have no expiration date. Accordingly, the Company is recording airtime credits as services are rendered and these airtime credits are recorded net of revenues from the country representatives.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2018
Accounting Policies [Abstract]
Basis of presentation	Basis of presentation The Company’s consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”). In the opinion of management, the financial statements as of December 31, 2018 and 2017 and for the years ended December 31, 2018, 2017 and 2016 include all adjustments (including normal recurring accruals) necessary for a fair presentation of the consolidated financial position, results of operations, comprehensive income and cash flows for the periods presented. The accompanying consolidated financial statements include the accounts of the Company, its wholly-owned and majority-owned subsidiaries and investments in variable interest entities in which the Company is determined to be the primary beneficiary. All significant intercompany accounts and transactions have been eliminated in consolidation. The portions of majority-owned subsidiaries that the Company does not own are reflected as noncontrolling interests on the consolidated balance sheet. Noncontrolling interests in companies are accounted for by the cost method where the Company does not exercise significant influence over the investee. Investments in entities over which the Company has the ability to exercise significant influence but does not have a controlling interest are accounted for under the equity method of accounting. The Company considers several factors in determining whether it has the ability to exercise significant influence with respect to investments, including, but not limited to, direct and indirect ownership level in the voting securities, active participation on the board of directors, approval of operating and budgeting decisions and other participatory and protective rights. Under the equity method, the Company’s proportionate share of the net income or loss of such investee is reflected in the Company’s consolidated results of operations. When the Company does not exercise significant influence over the investee, the investment is accounted for under the cost method. Although the Company owns interests in companies that it accounts for pursuant to the equity method, the investments in those entities had no carrying value as of December 31, 2018 and 2017. The Company has no guarantees or other funding obligations to those entities, and the Company had no equity in the earnings or losses of those investees for the years ended December 31, 2018, 2017 and 2016.
Use of estimates	Use of estimates The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the reported amounts of revenues and expenses at the date of the consolidated financial statements and during the reporting periods, and to disclose contingent assets and liabilities at the date of the consolidated financial statements. Actual results could differ from those estimates. The most significant estimates relate to recognition of revenue, allowances over accounts receivable, reserves over inventory balances, the recognition and measurement of assets acquired and liabilities assumed in business combinations at fair value, assessment of indicators of goodwill impairment, measurement of contingent considerations at fair value, determination of useful lives of the Company’s satellite network and other equipment and intangible assets, the assessment of expected cash flows used in evaluating long-lived assets, including intangible assets, for impairment, calculation of capitalized development costs, accounting for uncertainties in income tax positions, estimates associated with warranty costs and loss contingencies, estimates related to the recognition and subsequent valuation of contingent considerations and the value of securities underlying stock-based compensation.
Business combinations	Business combinations The Company accounts for business combinations pursuant to Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 805 “Business Combinations”, which requires that assets acquired and liabilities assumed be recorded at their respective fair values on the date of acquisition. The fair value of the consideration paid is assigned to the underlying net assets of the acquired business based on their respective fair values. Any excess of the purchase price over the estimated fair values of the net assets acquired is allocated to goodwill. The purchase price allocation process requires the Company to make significant assumptions and estimates in determining the purchase price and the fair value of assets acquired and liabilities assumed at the acquisition date. The Company’s assumptions and estimates are subject to refinement and, 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 conclusion of the measurement period, any subsequent adjustments are recorded to the Company’s consolidated statements of operations. The Company’s consolidated financial statements and results of operations reflect an acquired business after the completion of the acquisition.
Contingent consideration	Contingent consideration The Company determines the acquisition date fair value of contingent consideration obligations based on a probability-weighted income approach derived from milestone estimates and a probability assessment with respect to the likelihood of achieving performance metrics. The fair value measurement is based on significant inputs not observable in the market and thus represents a Level 3 measurement as defined in FASB ASC Topic 820 “Fair Value Measurement.” At each reporting date, the contingent consideration obligation will be revalued to estimated fair value and changes in fair value will be reflected as income or expense in the Company’s consolidated statement of operations. Changes in the fair value of the contingent consideration obligations may result from changes in probability assumptions with respect to the likelihood of achieving the various contingent payment obligations. Adverse changes in assumptions utilized in the Company’s contingent consideration fair value estimates could result in an increase in the Company’s contingent consideration obligation and a corresponding charge to operating income.
Acquisition-related and integration costs	Acquisition-related and integration costs Acquisition-related and integration costs include professional services expenses and identifiable integration costs directly attributable to acquisitions. For the years ended December 31, 2018, 2017 and 2016, the Company incurred acquisition-related and integration costs of $1,624, $3,315 and $1,630, respectively. These costs were expensed as incurred and are reflected in acquisition-related and integration costs on the Company’s consolidated statements of operations.
Revenue recognition	Revenue recognition On January 1, 2018, the Company adopted FASB Accounting Standards Update (“ASU”) No. 2014-09 “Revenue from Contracts with Customers” (“ASU 2014-09”). The Company reviewed its contract portfolio and determined its application of ASU 2014-09 did not have a material impact on the comparability of revenue recognized prior to the adoption of ASU 2014-09. The Company derives recurring service revenues mostly from monthly fees for industrial IoT connectivity services that consist of subscriber-based and recurring monthly usage fees for each subscriber communicator or SIM activated for use on its satellite network, other satellite networks and cellular wireless networks that the Company resells to its resellers, Market Channel Partners (“MCPs”) and Market Channel Affiliates (“MCAs”), and direct customers. In addition, the Company earns service revenues from subscription-based services providing recurring AIS data services to government and commercial customers worldwide. The Company also earns recurring service revenues from activations of subscriber communicators and SIMs, optional separately priced extended warranty service agreements extending beyond the initial warranty period, typically one year, which are billed to the customer upon shipment of a subscriber communicator, and royalty fees relating to the manufacture of subscriber communicators under a manufacturing agreement. Service revenues derived from usage fees are generally based upon the data transmitted by a customer, the overall number of subscriber communicators and/or SIMs activated by each customer, and whether the Company provides services through its value-added portal. Using the output method, these service revenues are recognized over time, as services are rendered, or at a point in time, based on the contract terms. AIS service revenues are generated over time from monthly subscription-based services supplying AIS data to its customers and resellers using the output method. Revenues from the activation of both subscriber communicators and SIMs are initially recorded as deferred revenues and are, thereafter, recognized on a ratable basis using a time-based output method, generally over three years, the estimated life of the subscriber communicator. Revenues from separately priced extended warranty service agreements extending beyond the initial warranty period, typically one year, are initially recorded as deferred revenues and are, thereafter, recognized on a ratable basis using a time-based output method, generally over two to five years. Revenues generated from royalties relating to the manufacture of subscriber communicators by third parties are recognized at a point in time when the third party notifies the Company of the units it has manufactured and a unique serial number is assigned to each unit by the Company. The Company earns other service revenues from installation services and engineering, technical and management support services. Revenues generated from installation services are recognized at a point in time using the output method when the services are completed. Revenues generated from engineering, technical and management support services are recognized over time as the service is provided. The Company also generates other service revenues through the sale of software licenses to its customers, which is recognized at a point in time using the output method when the license is provided to the customer. Product sales are derived from sales of complete industrial IoT telematics devices, modems or cellular wireless SIMs (for the Company’s terrestrial-communication services) to the Company’s resellers (i.e., MCPs and MCAs) and direct customers. Product sales are recognized at a point in time when title transfers, when the products are shipped or when customers accept the products, depending on the specific contractual terms. Sales of subscriber communicators and SIMs are not subject to return and title and risk of loss pass to the customer generally at the time of shipment. Amounts received prior to the performance of services under customer contracts are recognized as deferred revenues and revenue recognition is deferred until such time that all revenue recognition criteria have been met. Deferred revenue as of December 31, 2018 and 2017 consisted of the following: December 31, 2018 2017 Service activation fees $ 2,813 $ 5,509 Prepaid services 7,816 2,754 Extended warranty revenues 796 459 11,425 8,722 Less current portion (5,954 ) (6,263 ) Long-term portion $ 5,471 $ 2,459 During the years ended December 31, 2018 and 2017, the Company recognized revenue of $5,236 and $6,114, respectively, which had been included as deferred revenue as of December 31, 2017 and 2016. Shipping costs billed to customers are included in product sales and the related costs are included as cost of product sales on the Company’s consolidated statements of operations. The Company generates revenue from leasing arrangements of subscriber communicators, under FASB ASC Topic 840 “Leases” (“ASC 840”), using the estimated selling prices for each of the deliverables recognized. Product and installation revenues associated with these arrangements are recognized upon shipment or installation of the subscriber communicator, depending on the specific contractual terms. Service and warranty revenues are recognized on an accrual basis, as services are rendered, or on a cash basis, if collection from the customer is not reasonably assured at the time the service is provided. The following table summarizes the components of revenue from contracts with customers, as well as revenue recognized under ASC 840: Year Ended December 31, 2018 2017 2016 Revenue from contracts with customers: Recurring service revenues $ 148,367 $ 126,540 $ 106,515 Other service revenues 5,222 8,398 6,366 Total service revenues 153,589 134,938 112,881 Product sales 117,018 112,942 73,863 Total revenue from contracts with customers 270,607 247,880 186,744 Product sales recognized under ASC 840 5,533 6,340 — Total revenues $ 276,140 $ 254,220 $ 186,744
Revenue recognition for arrangements with multiple performance obligations	Revenue recognition for arrangements with multiple performance obligations The Company enters into contracts with its customers that include multiple performance obligations, which typically include subscriber communicators, monthly usage fees and optional extended warranty service agreements. The Company evaluates each item to determine whether it represents a promise to transfer a distinct good or service to the customer and therefore is a separate performance obligation under ASU 2014-09. If a contract is separated into more than one performance obligation, the Company allocates the total transaction price to each performance obligation in an amount based on the estimated relative stand-alone selling prices of each performance obligation. The Company uses an observable price to determine the stand-alone selling price for separate performance obligations when sold on its own or a cost-plus margin approach when one is not available. If an arrangement provided to a customer has a significant and incremental discount on future revenue, such right is considered a performance obligation and a proportionate amount of the discount should be allocated to each element based on the relative stand-alone selling price of each element, regardless of the discount. The Company has determined that arrangements provided to its customers do not include significant and incremental discounts. The Company has elected not to disclose the value of unsatisfied performance obligations since these obligations would have an original expected length of one year or less.
Costs of revenues	Costs of revenues The Company operates its own LEO satellite network and accompanying ground equipment, including fifteen gateway earth stations, three AIS data reception earth stations, and three regional gateway control centers. The Company’s proprietary satellite-based communications system is typically characterized by high initial capital expenditures and relatively low marginal costs for providing service. The Company resells network connectivity for two other satellite networks and seven terrestrial network partners. Reselling network connectivity typically involves a cost for each device connected to the network system and the amount paid to each provider will vary. Cost of services is comprised of expenses to operate the Company’s network, such as payroll and related costs, including stock-based compensation, installation costs, and usage fees to third-party networks. The Company mostly sells industrial IoT telematics devices and modems that the Company designs and builds with contract manufacturers. Cost of product sales includes the purchase price of subscriber communicators and SIMs sold, costs of warranty obligations, shipping charges, as well as operational costs of the Company’s employees and inventory management to fulfill customer orders.
Foreign currency translation	Foreign currency translation The Company has foreign operations where the functional currency is the local currency. For these operations, assets and liabilities are translated using end-of-period exchange rates and revenues, expenses and cash flows are translated using average rates of exchange for the period. Equity is translated at the rate of exchange at the date of the equity transaction. Translation adjustments are recognized in stockholders’ equity as a component of accumulated other comprehensive income (loss). Foreign currency transaction gains and losses related to assets and liabilities that are denominated in a currency other than the functional currency are included in other income (expense) on the consolidated statements of operations. Foreign currency translation gains and losses related to operational expenses denominated in a currency other than the functional currency are included in selling, general and administrative expenses (“SG&A”) on the consolidated statements of operations. For the years ended December 31, 2018, 2017 and 2016, the Company recorded a foreign currency translation loss of $76, $374, and $4, respectively.
Fair value of financial instruments	Fair value of financial instruments The Company has no financial assets or liabilities that are measured at fair value on a recurring basis. However, if certain triggering events occur, the Company is required to evaluate the non-financial assets for impairment and any resulting asset impairment would require that a non-financial asset be recorded at fair value. FASB ASC Topic 820 “Fair Value Measurement Disclosure,” prioritizes inputs used in measuring fair value into a hierarchy of three levels: Level 1- unadjusted quoted prices for identical assets or liabilities traded in active markets; Level 2- inputs other than quoted prices included within Level 1 that are either directly or indirectly observable; and Level 3- unobservable inputs in which little or no market activity exists, therefore requiring an entity to develop its own assumptions that market participants would use in pricing. The carrying amounts of the Company’s financial instruments, including cash, restricted cash, accounts receivable and accounts payable approximated their fair values due to the short-term nature of these items. The fair value of the Senior Secured Notes is based on observable relevant market information. Fluctuation between the carrying amount and the fair value of the Senior Secured Notes for the period presented is associated with changes in market interest rates. The Company may redeem all or part of the Senior Secured Notes at any time or from time to time at its option at specified redemption prices that would include “make-whole” premiums. Refer to “Note 10 – Notes Payable” for more information. The carrying amounts and fair values of the Company’s Senior Secured Notes are shown in the following table: December 31, 2018 December 31, 2017 Carrying Amount Fair Value Carrying Amount Fair Value Senior Secured Notes $ 250,000 $ 255,000 $ 250,000 $ 266,550 The fair value of the note payable-related party, $1,298 book value, has a de minimis value.
Cash and cash equivalents	Cash and cash equivalents The Company considers all liquid investments with original maturities of three months or less, at the time of purchase, to be cash equivalents. At December 31, 2018 and 2017, the Company had a cash balance of $53,766 and $34,830, respectively.
Concentration of risk	Concentration of risk The Company’s customers are primarily commercial organizations. Accounts receivable are generally unsecured. Accounts receivable are due in accordance with payment terms included in contracts negotiated with customers. Amounts due from customers are stated net of an allowance for doubtful accounts. The Company determines its allowance for doubtful accounts by considering a number of factors, including the length of time accounts are past due, the customer’s current ability to pay its obligations to the Company and the condition of the general economy and the industry as a whole. The Company writes off accounts receivable when they are deemed uncollectible. There were no customers with revenues greater than 10% of the Company’s consolidated total revenues for the years ended December 31, 2018 and 2016. For the year ended December 31, 2017, JB Hunt Transport Services, Inc. comprised 10.8% of the Company’s consolidated total revenues. There were no customers with accounts receivable greater than 10% of the Company’s consolidated accounts receivable as of December 31, 2018 and 2017. As of December 31, 2018, the Company did not maintain in-orbit insurance coverage for its ORBCOMM Generation 1 (“OG1”) or ORBCOMM Generation 2 (“OG2”) satellites to address the risk of potential systemic anomalies, failures or catastrophic events affecting its satellite constellation.
Inventories	Inventories Inventories are stated at the lower of cost or net realizable value, determined on a weighted average cost basis. At December 31, 2018 and 2017, inventory, net of inventory obsolescence, consisted primarily of finished goods and purchased parts to be utilized by its contract manufacturer totaling $27,701 and $34,465, respectively, and raw materials totaling $6,599 and $7,972, respectively. The Company reviews inventory quantities on hand, evaluates the realizability of inventories and adjusts the carrying value as necessary based on forecasted product demand. A provision, recorded in cost of product sales on the Company’s consolidated statements of operations, is made for potential losses on slow-moving and obsolete inventories, when identified.
Satellite network and other equipment, net	Satellite network and other equipment, net Satellite network and other equipment, net are stated at cost less accumulated depreciation and amortization. Major renewals and improvements are capitalized, while maintenance and repairs are charged to operations as incurred. Depreciation and amortization are recognized using the straight-line method over the estimated useful lives of the assets. Leasehold improvements are amortized over the shorter of their useful life or their respective lease term. The following table provides the range of estimated useful lives used for each asset type: Useful Life (years) Satellite network 10 Capitalized software 3-7 Computer hardware 3 Other 2-7 Satellite network includes costs of the constellation of satellites, and the ground and control facilities, consisting of gateway earth stations, gateway control centers and the network control center. As of December 31, 2018 and 2017, assets under construction primarily consist of costs associated with acquiring, developing and testing software and hardware for internal and external use that have not yet been placed into service. The Company capitalized interest on its Initial Term Loan Facility, as defined below, during the construction period of its satellites and began depreciating these costs upon the satellites being placed into service. Capitalized interest was added to the cost of the satellites prior to being placed in service. The Company capitalized interest and deferred issuance costs associated with these facilities through March 1, 2016, the date the final 11 OG2 satellites were placed in service. For the year ended December 31, 2016, interest capitalized was $744.
Valuation / Impairment of Long-lived assets	Valuation of long-lived assets Property and equipment and other long-lived assets are tested for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. The Company measures recoverability by comparing the carrying amount to the projected undiscounted cash flows the assets are expected to generate. An impairment loss is recognized to the extent the carrying value exceeds the fair value. The Company’s satellite constellation and related assets are evaluated as a single asset group whenever facts or circumstances indicate that the carrying value may not be recoverable. If indicators of impairment are identified, recoverability of long-lived assets is measured by comparing their carrying amount to the projected cash flows the assets are expected to generate. Determining whether an impairment has occurred typically requires the use of significant estimates and assumptions, including the allocation of cash flows to assets or asset groups and, if required, an estimate of fair value for those assets or asset groups. If a satellite were to fail while in orbit, the resulting loss would be charged to expense in the period it is determined that the satellite is not recoverable. The amount of any such loss would be reduced to the extent of insurance proceeds estimated to be received. During the years ended December 31, 2017 and 2016, an impairment loss of $31,224 and $10,680 was recorded, respectively, to write off the net book value relating to the Company’s in-orbit OG2 satellites. In addition, an impairment loss of $466 to write off the net book value related to one of the Company’s leased AIS satellites was recorded in the year ended December 31, 2016. There was no impairment loss recorded for the year ended December 31, 2018. See “Note 6 – Satellite Network and Other Equipment, Net” for additional details relating to the impairment of these satellites. Impairment of long-lived assets The Company reviews its long-lived assets and amortizable intangible assets whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. In connection with this review, the Company also re-evaluates the periods of depreciation and amortization for these assets. The Company recognizes an impairment loss when the sum of the future undiscounted net cash flows expected to be realized from the asset is less than its carrying amount. If an asset is considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the asset exceeds its fair value, which is determined using the projected discounted future net cash flows, using the appropriate discount rate.
Capitalized development costs for internal use	Capitalized development costs for internal use The Company capitalizes the costs of acquiring, developing and testing software to meet the Company’s internal needs. Capitalization of costs associated with software obtained or developed for internal use commences when both the preliminary project stage is completed and management has authorized further funding for the project, based on a determination that it is probable that the project will be completed and used to perform the function intended. Capitalized costs include only (1) external direct cost of materials and services consumed in developing or obtaining internal-use software, and (2) payroll and payroll-related costs for employees who are directly associated with and devote time to the internal-use software project. Capitalization of such costs ceases no later than the point at which the project is substantially complete and ready for its intended use. Internal-use software costs are amortized once the software is placed in service using the straight-line method over periods ranging from three to seven years.
Capitalized development costs for external use	Capitalized development costs for external use The Company capitalizes certain software development costs upon the establishment of technological feasibility. Technological feasibility is considered to have occurred upon completion of either a detail program design or a working model. Software development costs will be amortized over the estimated life of the product once it is has been released for commercial sale.
Capitalized patent defense costs	Capitalized patent defense costs The Company capitalizes costs incurred in connection with the defense of a patent the Company owns when the defense against the alleged infringer is deemed probable of success, and the costs will increase the value of the patent.
Goodwill	Goodwill Goodwill represents the excess of the purchase price over the underlying net tangible and intangible assets of the Company’s acquisitions. Goodwill is not amortized, but is tested for impairment on an annual basis and between annual tests whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. Goodwill is tested at the reporting unit level, which is defined as an operating segment or one level below the operating segment. The Company operates in one reportable segment which is its only reporting unit. The Company tests for an indication of goodwill impairment annually on November 30 or when an indicator of impairment exists, by comparing the fair value of the reporting unit to its carrying value. If there is an indication of impairment, the Company performs a “step two” test to measure the impairment. There was no impairment of goodwill for the years ended December 31, 2018, 2017 and 2016.
Intangible assets	Intangible assets Intangible assets that are not considered to have an indefinite life are amortized over their useful lives. Intangible assets include patents and technology, customer lists and trademarks. Intangible assets are amortized using the straight line method over the estimated useful lives of the assets.
Warranty costs	Warranty costs The Company accrues for warranty coverage on product sales estimated at the time of sale based on historical costs to repair or replace products for customers compared to historical product sales. The warranty accrual is included in accrued liabilities on the Company’s consolidated balance sheets. Separately-priced extended warranty coverage is recorded as warranty revenue over the term of the extended warranty coverage and the related warranty costs are recorded as incurred during the coverage period. Warranty coverage that includes additional services, such as repairs and maintenance of the product, is treated as a separate performance obligation and the related warranty and repairs/maintenance costs are recorded as incurred.
Income taxes	Income taxes The Company estimates its income taxes separately for each tax jurisdiction in which it conducts operations. This process involves estimating actual current tax expense and assessing temporary differences resulting from different treatment of items between book and tax which results in deferred tax assets and liabilities. The Company recognizes a change in income in tax rates on deferred tax assets and liabilities in the period that includes the enactment date. Valuation allowances are established when realization of deferred tax assets is not considered more likely than not. The Company recognizes the effect of tax law changes in the period of enactment. Changes in existing tax laws and rates, their related interpretations, and the uncertainty generated by the current economic environment may affect the amounts of the Company’s deferred tax liabilities or the valuations of the Company’s deferred tax assets over time. The Company’s accounting for deferred tax consequences represents management’s best estimate of future events that can be appropriately reflected in the accounting estimates. In determining whether the realization of deferred tax assets is considered to be more likely than not, the Company assesses the realizability of the deferred tax assets on a jurisdiction by jurisdiction basis. This assessment is dependent upon past operating results and projected profitability. The weight given to the positive and negative evidence is commensurate with the extent to which the evidence is objectively verified. The Company accounts for uncertainty in income tax positions using a two-step approach. The first step is to determine whether it is more likely than not that a tax position will be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position. The second step is to measure the tax position at the largest amount of benefit that is greater than 50% likely of being realized upon ultimate settlement. The Company recognizes interest and penalties related to uncertain tax positions in income tax expense.
Loss contingencies	Loss contingencies The Company accrues for costs relating to litigation, claims and other contingent matters when such liabilities become probable and reasonably estimable. Such estimates may be based on advice from third parties or on management’s judgment, as appropriate. Actual amounts paid may differ from amounts estimated, and such differences will be charged to operations in the period in which the final determination of the liability is made.
Pre-acquisition contingencies	Pre-acquisition contingencies The Company has evaluated pre-acquisition contingencies that existed as of the acquisition dates of the businesses acquired. If any pre-acquisition contingencies acquired as part of an acquisition become probable and estimable, the Company will record such amounts at fair market value in the measurement period or the Company’s results of operations after the measurement period, as applicable.
Stock-based compensation	Stock-based compensation The Company measures and recognizes stock-based compensation expense for equity-based payment awards made to employees and directors based on estimated fair values on the date of grant. For equity-based payment awards, the Company recognizes compensation expense over the service period, net of estimated forfeitures using the straight-line method. For awards with non-market performance conditions, an evaluation is made at the grant date and future periods as to the likelihood of the performance criteria being met. Compensation expense is adjusted for changes in the likelihood of achieving the performance condition until the vesting date. For liability-based awards with market performance conditions, compensation expense is revalued at the end of each quarter based on the awards’ fair value using the graded vesting attribution method over the vesting period.
Recent accounting pronouncements	Recent accounting pronouncements In February 2016, the FASB issued ASU No. 2016-02 “Leases (Topic 842)” (“ASU 2016-02”), which is effective for fiscal years beginning after December 15, 2018. ASU 2016-02 requires an entity to recognize assets and liabilities arising from a lease for both finance and operating leases, along with additional qualitative and quantitative disclosures. Early adoption is permitted. The Company will adopt ASU 2016-02 in the first quarter of 2019 utilizing the modified retrospective transition method. While the Company is continuing to assess the potential impact of ASU 2016-02, the Company estimates that the adoption of ASU 2016-02 will result in the recognition of right-of-use assets and lease liabilities for operating leases in the range of approximately $10 million to $15 million on its consolidated balance sheets, with no material impact to its consolidated statements of operations. In January 2017, the FASB issued ASU No. 2017-04 “Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment” (“ASU 2017-04”), which will be effective for fiscal years beginning after December 15, 2019. ASU 2017-04 removes Step 2 of the goodwill impairment test, which requires a hypothetical purchase price allocation. Under ASU 2017-04, goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. The adoption of this standard, which will be applied prospectively, is not expected to have a material impact on the Company’s consolidated financial statements.
