Accounting Policies [Abstract]

Principles of Consolidation

[A]	Principles of consolidation:
		The consolidated financial statements include the accounts of I.D. Systems, Inc. and its wholly owned subsidiaries, Asset Intelligence, LLC (“AI”), I.D. Systems GmbH (“IDS GmbH”), I.D. Systems (UK) Ltd (formerly Didbox Ltd.) (“IDS Ltd”) and Keytroller (which, as noted above, are collectively referred to herein as the “Company”). All material intercompany balances and transactions have been eliminated in consolidation.

Use of Estimates

[B]	Use of estimates:
		The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. The Company continually evaluates estimates used in the preparation of the financial statements for reasonableness. The most significant estimates relate to stock-based compensation arrangements, measurements of fair value of assets acquired and liabilities assumed and acquisition-related contingent consideration, realization of deferred tax assets, the impairment of tangible and intangible assets, inventory reserves, allowance for doubtful accounts, warranty reserves and deferred revenue and costs. Actual results could differ from those estimates.

Cash and Cash Equivalents

[C]	Cash and cash equivalents:
		The Company considers all highly liquid debt instruments with an original maturity of three months or less when purchased to be cash equivalents unless they are legally or contractually restricted. The Company’s cash and cash equivalent balances generally exceed FDIC limits.

Restricted cash at December 31, 2017 and 2018 consists of cash held in escrow for purchases from a vendor.

Investments

[D]	Investments:
		The Company’s investments include debt securities, U.S. Treasury Notes, government and state agency bonds, corporate bonds and commercial paper, which are classified as either available for sale, held to maturity or trading, depending on management’s investment intentions relating to these securities. All of the Company’s investments are currently classified as available for sale. Available for sale securities are measured at fair value based on quoted market values of the securities, with the unrealized gain and (losses) reported as comprehensive income or (loss). The Company has classified as short-term those securities that mature within one year and all other securities are classified as long-term. Realized gains and losses from the sale of available for sale securities are determined on a specific-identification basis. Net realized gains and losses from the sale of investment securities available for sale are included in “other income” in the consolidated statement of operations. Dividend and interest income are recognized when earned.

Accounts Receivable

[E]	Accounts receivable:
		Accounts receivable are recorded at the invoiced amount and do not bear interest. Amounts collected on trade accounts receivable are included in net cash provided by operating activities in the consolidated statements of cash flows. The Company maintains reserves against its accounts receivable for potential losses. Allowances for uncollectible accounts are estimated based on the Company’s periodic review of accounts receivable balances. In establishing the required allowance, management considers our customers’ financial condition, the amount of receivables in dispute, and the current receivables aging and current payment patterns. Account balances are charged off against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. Accounts receivable are net of an allowance for doubtful accounts in the amount of $87,000 and $67,000 in 2017 and 2018, respectively. The Company does not have any off-balance sheet credit exposure related to its customers.

Financing Receivables

[F]	Financing receivables:
		Financing receivables consists of sales-type lease receivables from the sale of the Company’s products and services. These arrangements meet the criteria to be accounted for as sales-type leases. Accordingly, an asset is established for the “sales-type lease receivable” at the present value of the future minimum lease payments. Amounts collected on sales-type leases are included in net cash provided by operating activities in the consolidated statements of cash flows. Interest income is recognized monthly over the lease term using the effective-interest method.
		The allowance for uncollectable minimum lease payments represents the Company’s best estimate of the amount of credit losses in the Company’s existing notes and sales-type lease receivable. The allowance is determined on an individual lease basis if it is probable that the Company will not collect all principal and interest contractually due. The Company considers our customers’ financial condition and historical payment patterns in determining the customers’ probability of default. The impairment is measured based on the present value of expected future cash flows discounted at the note’s effective interest rate. There were no impairment losses recognized for the years ended December 31, 2016, 2017 and 2018. The Company does not accrue interest when a lease is considered impaired. When the ultimate collectability of the principal balance of the impaired lease is in doubt, all cash receipts on impaired lease are applied to reduce the principal amount of such lease until the principal has been recovered and are recognized as interest income thereafter. Impairment losses are charged against the allowance and increases in the allowance are charged to bad debt expense. Leases are written off against the allowance when all possible means of collection have been exhausted and the potential for recovery is considered remote. The Company resumes accrual of interest when it is probable that the Company will collect the remaining principal and interest of an impaired lease. Leases become past due based on how recently payments have been received.

Revenue Recognition

[G]	Revenue recognition:
		The Company’s revenue is derived from: (i) sales of our wireless asset management systems and spare parts; (ii) remotely hosted SaaS agreements and post-contract maintenance and support agreements; (iii) services, which includes training and technical support; and (iv) periodically, leasing arrangements. Amounts invoiced to customers which are not recognized as revenue are classified as deferred revenue and classified as short-term or long-term based upon the terms of future services to be delivered.
		Revenue is recognized when obligations under the terms of a contract with our customer are satisfied; generally this occurs with the transfer of control of our wireless asset management systems, spare parts, or services. Revenue is measured as the amount of consideration we expect to receive in exchange for transferring goods or providing services. Sales, value add, and other taxes we collect concurrent with revenue-producing activities are excluded from revenue. Incidental items that are immaterial in the context of the contract are recognized as expense. The expected costs associated with our base warranties continue to be recognized as expense when the products are sold (see Note 13). We recognize revenue for remotely hosted SaaS agreements and post-contract maintenance and support agreements beyond our standard warranties over the life of the contract.
		Our industrial truck and connected vehicle wireless asset management systems consist of on-asset hardware, communication infrastructure, SaaS, and hosting infrastructure. The Company’s system is typically implemented by the customer or a third party and, as a result, revenue related to the on-asset hardware is recognized when control of the hardware is transferred to the customer, which usually is upon delivery of the system and contractual obligations have been satisfied. Revenue related to the SaaS and hosting infrastructure performance obligation is recognized over time as access to the SaaS and hosting infrastructure is provided to the customer. In some instances, we are also responsible for providing installation services, training and technical support services which are short-term in nature and revenue for these services are recognized at the time of performance or right to invoice.
		Our logistics visibility solutions systems (formerly “transportation asset management”) consist of on-asset hardware, communications and SaaS services. The logistics visibility solutions system does not have stand-alone value to the customer separate from the SaaS services provided and, therefore, we consider both hardware and SaaS services a bundled performance obligation. Under the applicable accounting guidance, all of the Company’s billings for equipment and the related cost are deferred, recorded, and classified as a current and long-term liability and a current and long-term asset, respectively. Deferred revenue and cost are recognized over the service contract life, ranging from one to five years, beginning at the time that a customer acknowledges acceptance of the equipment and service. The customer service contracts typically range from one to five years. Spare parts sales are reflected in product revenues and recognized on the date of customer receipt of the part. In addition, the service revenue for our logistics visibility monitoring equipment relates to charges for monthly messaging usage and value-added features charges. The usage fee is a monthly fixed charge based on the expected utilization according to the rate plan chosen by the customer. Service revenue generally commences upon equipment installation and customer acceptance and is recognized over the period such services are provided.
		The Company also enters into remotely hosted SaaS agreements and post-contract maintenance and support agreements for its wireless asset management systems. Revenue is recognized ratably over the service periods and the cost of providing these services is expensed as incurred. Deferred revenue also includes prepayment of extended maintenance, hosting and support contracts.
		The Company also derives revenue under leasing arrangements. Such arrangements provide for monthly payments covering the system sale, maintenance, support and interest. These arrangements meet the criteria to be accounted for as sales-type leases. Accordingly, an asset is established for the “sales-type lease receivable” at the present value of the expected lease payments and revenue is deferred and recognized over the service contract, as described above. Maintenance revenues and interest income are recognized monthly over the lease term.
		Our contracts with customers may include multiple performance obligations. For such arrangements, we allocate revenue to each performance obligation based on its relative standalone selling price. We generally determine standalone selling prices based on observable prices charged to customers or adjusted market assessment or using expected cost-plus margin when one is available. Adjusted market assessment price is determined based on overall pricing objectives taking into consideration market conditions and entity specific factors.
		The Company recognizes an asset for the incremental costs of obtaining the contract arising from the sales commissions to employees because the Company expects to recover those costs through future fees from the customers. The Company amortizes the asset over three to five years because the asset relates to the services transferred to the customer during the contract term of three to five years.
		Sales taxes collected from customers and remitted to governmental authorities are accounted for on a net basis and therefore are excluded from revenues in the Consolidated Statements of Operations.

Deferred Costs

[H]	Deferred costs:
		Deferred product costs consist of logistics visibility solutions equipment costs deferred in accordance with our revenue recognition policy. The Company will continue to evaluate the realizability of the carrying amount of the deferred contract costs on a quarterly basis. To the extent the carrying value of the deferred contract costs exceed the contract revenue, an impairment loss will be recognized.

Inventory

[I]	Inventory:
		Inventory, which primarily consists of finished goods and components used in the Company’s products, is stated at the lower of cost or net realizable value using the first-in first-out (FIFO) method.
		Inventory valuation reserves are established in order to report inventories at the lower of cost or net realizable value in the consolidated balance sheet. The determination of inventory valuation reserves requires management to make estimates and judgments on the future salability of inventories. Valuation reserves for obsolete and slow-moving inventory are estimated based on assumptions of future sales forecasts, product life cycle expectations, the impact of new product introductions, production requirements, and specific identification of items, such as product discontinuance or engineering/material changes and by comparing the inventory levels to historical usage rates.

Fixed Assets and Depreciation

[J]	Fixed assets and depreciation:
		Fixed assets are recorded at cost and depreciated using the straight-line method over the estimated useful lives of the assets, which range from three to ten years. Leasehold improvements are amortized using the straight-line method over the terms of the respective leases, or their estimated useful lives, whichever is shorter. For website development costs, the Company capitalizes costs incurred during the application development stage. Costs related to preliminary project activities and post-implementation activities are expensed as incurred. Internal-use software is amortized on a straight-line basis over its estimated useful life, generally three years.

Long-lived Assets

[K]	Long-lived assets:
		Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of the assets to the future undiscounted net cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets and would be charged to earnings. Fair value is determined through various valuation techniques including discounted cash flow models, quoted market values and third-party independent appraisals, as considered necessary.

Business Combinations

[L]	Business Combinations:
		Goodwill represents costs in excess of fair values assigned to the underlying net assets of acquired businesses. Goodwill and intangible assets deemed to have indefinite lives are not amortized. Intangible assets other than goodwill are amortized over their useful lives unless the lives are determined to be indefinite. Intangible assets are carried at cost, less accumulated amortization. Intangible assets consist of trademarks and trade name, patents, customer relationships and other intangible assets. The Company tests goodwill and other intangible assets annually, or when a triggering event occurs between annual impairment tests, to determine if impairment exists and if the use of indefinite lives is currently applicable. For purposes of the goodwill impairment test, the Company’s product lines are aggregated within one reporting unit. For the years ended December 31, 2016, 2017 and 2018, the Company has not incurred an impairment charge. The Company re-measures the fair value of the contingent consideration at each reporting period and any change in the fair value from either the passage of time or events occurring after the acquisition date, is recorded in earnings in the accompanying consolidated statement of operations. Actual results could differ from such estimates in future periods based on the re-measurement of the fair value.

Product Warranties

[M]	Product warranties:
		The Company typically provides a one-year warranty on its products. Estimated future warranty costs are accrued in the period that the related revenue is recognized. These estimates are derived from historical data and trends of product reliability and costs of repairing and replacing defective products.

Research and Development

[N]	Research and development:
		Research and development costs are charged to expense as incurred and consists primarily of salaries and related expenses, supplies and contractor costs. Research and development costs were $5,235,000, $4,538,000 and $6,863,000 in 2016, 2017 and 2018, respectively.

Patent Costs

[O]	Patent costs:
		Costs incurred in connection with acquiring patent rights are charged to expense as incurred.

Benefit Plan

[P]	Benefit plan:
		The Company maintains a retirement plan under Section 401(k) of the Internal Revenue Code, which covers all eligible employees. All employees with U.S. source income are eligible to participate in the plan immediately upon employment. The Company did not make any contributions to the plan during the years ended December 31, 2016, 2017 and 2018.

Rent Expense

[Q]	Rent expense:
		Expense related to the Company’s facilities leases is recorded on a straight-line basis over the respective lease terms. The difference between rent expense incurred and the amounts required to be paid in accordance with the lease term is recorded as deferred rent and is amortized over the lease term.

Stock-based Compensation

[R]	Stock-based compensation:
		The Company accounts for stock-based employee compensation for all share-based payments, including grants of stock options and restricted stock, as an operating expense based on their fair values on grant date. The Company recorded stock-based compensation expense of $1,658,000, $2,437,000 and $2,163,000 for the years ended December 31, 2016, 2017 and 2018, respectively.
		The Company estimates the fair value of share-based option awards on the grant date using an option pricing model. The value of the portion of the award that is ultimately expected to vest is recognized as expense over the requisite service period in the Company’s consolidated statement of operations. The Company estimates forfeitures at the time of grant in order to estimate the amount of share-based awards that will ultimately vest. The estimate is based on the Company’s historical rates of forfeitures. Estimated forfeitures are revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates.

Income Taxes

[S]	Income taxes:
		The Company uses the asset and liability method of accounting for deferred income taxes. Deferred income taxes are measured by applying enacted statutory rates to net operating loss carryforwards and to the differences between the financial reporting and tax bases of assets and liabilities. Deferred tax assets are reduced, if necessary, by a valuation allowance if it is more likely than not that some portion or all of the deferred tax assets will not be realized.
		The Company recognizes uncertainty in income taxes in the financial statements using a recognition threshold and measurement attribute of a tax position taken or expected to be taken in a tax return. The Company applies the “more-likely-than-not” recognition threshold to all tax positions, commencing at the adoption date of the applicable accounting guidance, which resulted in no unrecognized tax benefits as of such date. Additionally, there have been no unrecognized tax benefits subsequent to adoption. The Company has opted to classify interest and penalties that would accrue according to the provisions of relevant tax law as selling, general, and administrative expenses, in the consolidated statement of operations. For the years ended December 31, 2016, 2017 and 2018, there was no such interest or penalty.
		The Company files federal income tax returns and separate income tax returns in various states. For federal and certain states, the 2015 through 2018 tax years remain open for examination by the tax authorities under the normal three-year statute of limitations. For certain other states, the 2014 through 2018 tax years remain open for examination by the tax authorities under a four-year statute of limitations.

Fair Value of Financial Instruments

[T]	Fair value of financial instruments:
		Cash and cash equivalents and investments in securities are carried at fair value. The carrying value of financing receivables approximates fair value due to the interest rate implicit in the instruments approximating current market rates. The carrying value of accounts receivable, accounts payable and other liabilities approximates their fair values due to the short period to maturity of these instruments.

Advertising and Marketing Expense

[U]	Advertising and marketing expense:
		Advertising and marketing costs are expensed as incurred. Advertising and marketing expense for the years ended December 31, 2016, 2017 and 2018 amounted to $510,000, $538,000 and $996,000, respectively.

Commitments and Contingencies

[V]	Commitments and contingencies:
		Liabilities for loss contingencies arising from claims, assessments, litigation, fines, and penalties and other sources are recorded when it is probable that a liability has been incurred and the amount can be reasonably estimated.

Recently Issued Accounting Pronouncements

[W]	Recently issued accounting pronouncements:
		In August 2018, the Securities and Exchange Commission (the “SEC”) issued a final rule that amends certain of the SEC’s disclosure requirements, including requirements relating to disclosures about changes in stockholders’ equity. For Quarterly Reports on Form 10-Q, the final rule extends to interim periods the annual requirement in Rule 3-04 of Regulation S-X, to disclose (1) changes in stockholders’ equity and (2) the amount of dividends per share for each class of shares (as opposed to common stock only, as previously required). Pursuant to the final rule, registrants must now analyze changes in stockholders’ equity, in the form of a reconciliation, for “the current and comparative year-to-date [interim] periods, with subtotals for each interim period,” i.e., a reconciliation covering each period for which an income statement is presented. Rule 3-04 of Regulation S-X permits the disclosure of changes in stockholders’ equity (including dividend-per-share amounts) to be made either in a separate financial statement or in the notes to the financial statements. The final rule is effective for all filings made on or after November 5, 2018. SEC staff has indicated it would not object if a registrant’s first presentation of the changes in shareholders’ equity is included in its Form 10-Q for the quarter that begins after the effective date of the amendments. Therefore, the Company expects to conform to this rule in its Quarterly Report on Form 10-Q for the quarter ending March 31, 2019. Inasmuch as the Company has not paid dividends, the Company believes that the final rule will not have a material effect on its consolidated financial statements and disclosures.
		In August 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2018-15, “Intangibles-Goodwill and Other-Internal-Use Software (Topic 350): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract”, which align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal use software license). ASU 2018-15 is effective for the Company beginning in the first fiscal quarter of 2022, with early adoption permitted. The Company is currently evaluating the impact of this ASU on the consolidated financial statements.
		In June 2018, the FASB issued ASU 2018-07, “Compensation - Stock Compensation (Topic 718): Improvements to Non-employee Share-Based Accounting”. This guidance aligns the accounting for share-based payment transactions with non-employees to accounting for share-based payment transactions with employees. Companies are required to record a cumulative-effect adjustment (net of tax) to retained earnings as of the beginning of the fiscal year of the adoption. Upon transition, non-employee awards are required to be measured at fair value as of the adoption date. This standard will be effective for fiscal years beginning December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. The Company does not expect the adoption of this standard to have a material impact on the consolidated financial statements.
		In February 2018, the FASB issued ASU 2018-02, “Income Statement - Reporting Comprehensive Income (Topic 220)”. The objective of the ASU is to allow a reclassification from accumulated comprehensive income (loss) to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act and will improve the usefulness of information reported to financial statement users. This ASU is effective for interim and annual reporting periods beginning after December 15, 2018, and early adoption is permitted. The Company does not expect the adoption of this standard to have a material impact on the consolidated financial statements.
		In May 2017, the FASB issued ASU 2017-09, “Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting”. The FASB issued the update to provide clarity and reduce the cost and complexity when applying the guidance in Topic 718. The amendments in this update provide guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting in Topic 718. This ASU was effective for public companies for fiscal years beginning after December 15, 2017, including interim periods. Early adoption is permitted. The adoption of this guidance did not have a material impact on the Company’s financial results.
		In January 2017, the FASB issued ASU 2017-04, “Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment,” which simplifies how an entity is required to test goodwill for impairment by eliminating Step 2 from the goodwill impairment test. Step 2 measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill. Under the amendments in ASU 2017-04, an entity should recognize an impairment charge for the amount by which the carrying amount of a reporting unit exceeds its fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. The updated guidance requires a prospective adoption. The guidance is effective beginning fiscal year 2021. Early adoption is permitted. The Company is currently evaluating the impact of this ASU on the consolidated financial statements.

In November 2016, the FASB issued ASU No. 2016-18, “Statement of Cash Flows (Topic 230): Restricted Cash,” which requires the inclusion of restricted cash with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. This ASU was effective for public business entities for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The adoption of this guidance did not have a material impact on the Company’s financial results.

In August 2016, the FASB issued ASU No. 2016-15, “Statement of Cash Flows (Topic 230) - Classification of Certain Cash Receipts and Cash Payments,” which provides clarification on how companies present and classify certain cash receipts and cash payments in the statement of cash flows. This ASU was effective for fiscal periods beginning after December 15, 2017 and interim periods within those fiscal years. Early adoption is permitted. If an entity early adopts the amendments in an interim period, any adjustments must be reflected as of the beginning of the fiscal year that includes that interim period. An entity that elects early adoption must adopt all of the amendments in the same period. The adoption of this guidance did not have a material impact on the Company’s financial results.

In June 2016, the FASB issued ASU No. 2016-13, “Financial Instruments - Credit Losses (Topic 326) Measurement of Credit Losses on Financial Instruments,” which amends the guidance on measuring credit losses on financial assets held at amortized cost. The amendment is intended to address the issue that the previous “incurred loss” methodology was restrictive for an entity’s ability to record credit losses based on not yet meeting the “probable” threshold. The new language will require these assets to be valued at amortized cost presented at the net amount expected to be collected with a valuation provision. This update standard is effective for fiscal years beginning after December 15, 2019. The Company is currently evaluating the impact of this ASU on the consolidated financial statements.

In February 2016, the FASB issued ASU 2016-02, “Leases” (Topic 842), in order to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet for those leases classified as operating leases under previous GAAP. ASU 2016-02 requires that a lessee should recognize a liability to make lease payments (the lease liability) and a right-of-use asset representing its right to use the underlying asset for the lease term on the balance sheet. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018 (including interim periods within those periods) using a modified retrospective approach and early adoption is permitted. The Company will adopt ASU 2016-02 in the first quarter of 2019. A modified retrospective transition approach is required, applying the new standard to all leases existing at the date of initial application. An entity may choose to use either (1) its effective date or (2) the beginning of the earliest comparative period presented in the financial statements as its date of initial application. If an entity chooses the second option, the transition requirements for existing leases also apply to leases entered into between the date of initial application and the effective date. The entity must also recast its comparative period financial statements and provide the disclosures required by the new standard for the comparative periods. The Company will adopt the new standard on January 1, 2019 and use the effective date of initial application. Consequently, financial information will not be updated and the disclosures required under the new standard will not be provided for dates and periods before January 1, 2019. The new standard provides a number of optional practical expedients in transition. The Company expects to elect the “package of expedients”, which permits the Company not to reassess under the new standard the Company’s prior conclusions about lease identification and initial direct costs. The Company does not expect to elect the use-of hindsight or the practical expedient pertaining to land easements, the latter not being applicable to the Company. The new standard also provides practical expedients for the Company’s ongoing accounting. The Company currently expects to elect the short-term lease recognition exemption for all leases that qualify. This means, for those leases that qualify, the Company will not recognize ROU assets or lease liabilities, and this includes not recognizing ROU assets or lease liabilities for existing short-term leases of those assets in transition. The Company also expects to elect the practical expedient to not separate lease and non-lease components for all of its leases other than leases of real estate. The Company expects the most significant change will be related to the recognition of right-of-use assets and lease liabilities on the Company’s balance sheet for real estate operating leases. The Company is currently in the process of evaluating the impact of ASU 2016-02 on the Company’s outstanding leases and expects that as a result of the adoption of this guidance that it will record right-of-use assets and lease liabilities totaling approximately $2.8 million to $3.2 million primarily related to its real estate operating leases. The Company also expects that the adoption of this guidance will result in additional lease-related disclosures in the footnotes to its consolidated financial statements.

In May 2014, the FASB issued ASU 2014-09 (Topic 606) “Revenue from Contracts with Customers.” Topic 606 supersedes the revenue recognition requirements in Topic 605 “Revenue Recognition” (Topic 605) and requires entities to recognize revenue when control of the promised goods or services is transferred to customers at an amount that reflects the consideration to which the entity expects to be entitled to in exchange for those goods or services. On January 1, 2018, we adopted Topic 606 and all related amendments (“new revenue standard”) to those contracts which were not completed as of January 1, 2018 using the modified retrospective method. The comparative information was not been restated and continues to be reported under the accounting standards in effect for those periods. There was no adjustment to the opening balance of retained earnings due to the cumulative effect of initially applying the new revenue standard determined to be immaterial.

Reclassifications

[X]	Reclassifications:
		Certain amounts included in selling, general and administrative expenses in the prior years’ consolidated financial statements have been reclassified to research and development expenses to conform to the current period presentation for comparative purposes. In addition, the reconciliation of cash and restricted cash in the consolidated statement of cash flows has been included for the prior years.
