Accounting Policies [Abstract]
Significant Accounting Policies	2 . Basis of Presentation These consolidated financial statements are presented in accordance with generally accepted accounting principles in the United States (“U.S. GAAP”). The consolidated financial statements were prepared on a going concern basis, under the historical cost convention except for certain financial instruments that are measured at fair value on a recurring basis, as explained in the accounting policies below. Historical cost is measured as the fair value of the consideration provided in exchange for goods and services on the date of the transaction. All financial information is presented in thousands of U.S. dollars, except as otherwise indicated. Basis of Consolidation These consolidated financial statements include the accounts of Quarterhill and its wholly-owned subsidiaries. Quarterhill also holds, through one of its subsidiaries, a 50% joint venture ownership interest in Xuzhou-PAT Control Technologies Limited (“XPCT”) which is accounted for using the equity method. These consolidated financial statements include only the Company’s net investment and equity in earnings of the joint venture. All inter-company transactions and balances have been eliminated in these consolidated financial statements. The significant accounting policies are summarized below: Estimates and Assumptions The preparation of 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 disclosure of contingent assets and liabilities at the dates of the financial statements and the reported amounts of revenues and expenses during the years. Actual results could differ from those estimates. The significant accounting policies contained herein include estimates and assumptions with respect to the determination of fair values of tangible and intangible assets acquired in business combinations, best estimate of stage of completion of contracted projects, identification of distinct performance obligations, in contracts with customers and the related stand alone selling prices, recoverability of financial assets and equity investments, income tax and the recoverability of deferred tax assets, determination of indicators of impairment and related impairment assessments. Business Combinations The Company applies the provisions of the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 805, “Business Combinations”, in the accounting for its acquisitions. This requires the Company to recognize separately from goodwill the assets acquired and the liabilities assumed at their acquisition date fair values. Goodwill as of the acquisition date is measured as the excess of consideration transferred over the net of the acquisition date fair values of the assets acquired and the liabilities assumed. While the Company uses its best estimates and assumptions to accurately value assets acquired and liabilities assumed at their fair values, including contingent consideration where applicable, these estimates are inherently uncertain and subject to refinement, particularly since these assumptions and estimates are based in part, on historical experience and information obtained from the management of the acquired companies. As a result, during the measurement period, which may be up to one year from the acquisition date, the Company may record adjustments to the assets acquired and liabilities assumed with the corresponding offset to goodwill in the period identified. Furthermore, when valuing certain intangible assets that the Company has acquired, critical estimates may be made relating to, but not limited to: (i) future expected cash flows from customer relationships, software license sales, support agreements, consulting agreements and other customer contracts; (ii) the acquired entity’s brand and competitive position, as well as assumptions about the period of time that the acquired brand will continue to be used in the combined Company’s product portfolio; and (iii) discount rates. Upon the conclusion of the measurement period or final determination of the values of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments would be recorded to the Company’s consolidated statements of operations, on a cumulative basis, in the period in which the adjustment is determined. For a given acquisition, the Company identifies certain pre-acquisition contingencies as of the acquisition date and may extend its review and evaluation of these pre-acquisition contingencies throughout the measurement period to obtain sufficient information to assess whether the Company includes these contingencies as a part of the purchase price allocation and, if so, to determine the estimated amounts. If the Company determines that a pre-acquisition contingency (non-income tax related) is probable in nature and estimable as of the acquisition date, then it will record its best estimate for such a contingency as a part of the preliminary purchase price allocation. The Company continues to gather information and evaluates any pre-acquisition contingencies throughout the measurement period and makes adjustments as necessary either directly through the purchase price allocation or in its results of operations. Uncertain tax positions and tax related valuation allowances assumed in connection with a business combination are initially estimated as of the acquisition date. The Company reviews these items during the measurement period as the Company continues to actively seek and collect information relating to facts and circumstances that existed at the acquisition date. Changes to these uncertain tax positions and tax related valuation allowances made subsequent to the measurement period, or if they relate to facts and circumstances that did not exist at the acquisition date, are recorded in the Company’s provision for income taxes in the consolidated statements of operations. Fair Value Measurement of Financial Instruments The Company uses various valuation techniques and assumptions when measuring fair value of its financial assets and financial liabilities. The Company utilizes market data or assumptions that market participants would use in pricing the asset or liability, including assumptions about risk and the risks inherent in the inputs to the valuation technique. The accounting standard establishes a hierarchy that prioritizes fair value measurements based on the types of input used for the various valuation techniques (market approach, income approach and cost approach). The levels of the hierarchy are described below: Level 1 Inputs — Level 1 includes financial instruments for which quoted market prices for identical instruments are available in active markets. Level 2 Inputs — Level 2 includes financial instruments for which there are inputs other than quoted prices included within Level 1 that are observable for the instrument such as quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets with insufficient volume or infrequent transactions (less active markets) or model-driven valuations in which significant inputs are observable or can be derived principally from, or corroborated by, observable market data, including market interest rate curves, referenced credit spreads and pre-payment rates. Level 3 Inputs — Level 3 includes financial instruments for which fair value is derived from valuation techniques including pricing models and discounted cash flow models in which one or more significant inputs are unobservable, including the Company’s own assumptions. The pricing models incorporate transaction details such as contractual terms, maturity and, in certain instances, timing and amount of future cash flows, as well as assumptions related to liquidity and credit valuation adjustments of marketplace participants. The following methods and assumptions were used to estimate the fair value of each class of financial instruments for which it is practicable to estimate that value. Patent finance obligations: The fair values are estimated based on the quoted market prices for those or similar instruments or on the current rates offered to the Company for debt of similar terms. Derivative financial instruments: The fair value of embedded derivatives is measured using a market approach, based on the difference between the quoted forward exchange rate as of the contract date and quoted forward exchange rate as of the reporting date. The fair value of forward exchange contracts is determined using the quoted forward exchange rates at the reporting date. Contingent considerations: Contingent consideration is carried at fair value which is calculated using management estimates or, where appropriate, a Monte Carlo simulation model. Long-term debt: The fair value is estimated based on the quoted market prices for those or similar instruments or on the current rates offered to the Company for debt of similar terms. The carrying amount of the Company’s other financial assets and liabilities, including cash, accounts receivable, and accounts payable and accrued liabilities approximate their fair value due to the short-term maturity of these items. The fair value of the bank indebtedness and long-term debt approximate the carrying amount since these debt instruments all have floating interest rates. Derivatives The Company uses derivative financial instruments to reduce exposure to fluctuation in foreign currency exchange rates. The Company may enter into foreign exchange contracts to hedge anticipated cash flows denominated in a foreign currency. The Company has elected not to apply hedge accounting to derivative contracts; as such, these derivative financial instruments are recorded at fair market value on a recurring basis, with subsequent changes in fair value recorded in other income (expense) during the period of change. Derivatives are carried at fair value and are reported as assets when they have a positive fair value and as liabilities when they have a negative fair value. Derivatives may also be embedded in other financial instruments. Derivatives embedded in other financial instruments are valued as separate derivatives if they meet the bifurcation criteria of an embedded derivative. Such criteria include that the entire instrument is not marked to market through earnings, the economic characteristics and risks of the embedded contract terms are not clearly and closely related to those of the host contract and the embedded contract terms would meet the definition of a derivative on a stand-alone basis. Foreign Currency Transactions Monetary assets and liabilities denominated in foreign currencies are translated into the applicable functional currency of the entity at exchange rates prevailing at the balance sheet date. Revenue and expenses are translated at the average rate for the period. The gains and losses from foreign currency denominated transactions are included in foreign exchange gain/loss in the consolidated statement of operations. Foreign Currency Translation The consolidated financial statements are presented in U.S. dollars. The functional currency of each subsidiary is the currency of the primary economic environment in which the subsidiary operates. For each subsidiary, assets and liabilities denominated in this functional currency are translated into U.S. dollars at the exchange rates in effect at the balance sheet dates and revenues and expenses are translated at the average exchange rates prevailing during the month of the respective transactions. The effect of foreign currency translation adjustments not affecting net income are included in Shareholders’ equity under the “Cumulative translation adjustment” account as a component of “Accumulated other comprehensive income”. Cash and Cash Equivalents Cash and cash equivalents consist of cash in banks and highly liquid investments with original terms to maturity at the date of acquisition of less than three months. Short-Term Investments Short-term investments are designated as “held to maturity” and accounted for at amortized cost using the effective interest rate method. Short-term investments comprise guaranteed investment certificates with original maturities of one-year or less at the date of investment and their carrying value approximates their fair value. Restricted Short-Term Investments Restricted short-term investments are amounts held specifically as collateral for bank guarantees that the Company has entered into for security against potential procedural costs pursuant to a court order regarding patent infringement whereby the Company is the plaintiff. The bank guarantees total 1,850,000 Euros and are valid until March 28, 2019. They are automatically extended by periods of one year unless either party informs the other party at least sixty days before the current expiry date that they elect not to extend the bank guarantee. The restricted short-term investment acts as collateral should this renewal not take place and/or the requirement for the security and hence, the restricted short-term investments is no longer required by the court. Accounts Receivable, Net The accounts receivable balance reflects invoices and is presented net of an allowance for doubtful accounts. The allowance for doubtful accounts represents the Company’s best estimate of probable losses that may result from the inability of its customers to make required payments. Reserves are established and maintained against estimated losses based upon historical loss experience, past due accounts and specific account analysis. The Company regularly reviews the level of allowances for doubtful accounts and adjusts the level of allowances as needed. Consideration is given to accounts past due as well as other risks in the current portion of the accounts. Unbilled Revenue Unbilled Revenue includes unbilled amounts typically resulting from sales under long-term contracts when the cost-to-cost method of revenue recognition is utilized and revenue recognized exceeds the amount billed to the customer accounted for under Accounting Standards Update No. 2014-09 “Revenue from Contracts with Customers” (“ASC 606”). Inventories Inventories are measured at the lower of cost or net realizable value. The cost of inventories is determined on the weighted average basis. Cost includes the cost of acquired material plus, in the case of manufactured inventories, direct labor applied to the product and the applicable share of manufacturing overhead, including rent expense and depreciation based on normal operating capacity. Property Plant and Equipment Property plant and equipment is carried at cost less accumulated depreciation and impairment. Depreciation is calculated on the straight-line basis over the estimated useful lives of the assets as follows: Leasehold improvements term of the lease Computer equipment and software 3 years Furniture and fixtures 5 years Machinery and equipment 4-7 years Building 20 years Intangible Assets Intangibles consist of patents, developed software, customer relationships and brand associated with various acquisitions. Patents include patents and patent rights (hereinafter, collectively “patents”) and are carried at cost less accumulated amortization and impairments. Developed software is initially recorded at fair value based on the present value of the estimated net future income-producing capabilities of software products acquired in acquisitions. Brand is initially recorded at fair value based on the present value of the estimated net future income-producing capabilities of the asset. Customer relationships represent acquired customer relationships with customers of acquired companies and are either based upon contractual or legal rights or are considered separable; that is, capable of being separated from the acquired entity and being sold, transferred, licensed, rented or exchanged. These customer relationships are initially recorded at their fair value based on the present value of expected future cash flows. Amortization is calculated on a straight-line basis over the estimated useful lives of the intangible assets as follows: Patents up to 20 years Developed Software 5 years Customer relationship and backlog 7 years Brand 7 years The Company continually evaluates the remaining estimated useful life of its intangible assets being amortized to determine whether events and circumstances warrant a revision to the remaining period of amortization. Impairment of Long-Lived Assets The Company reviews long-lived assets (“LLA”) such as property and equipment and intangible asset groups for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset or asset group may not be recoverable. These events and circumstances may include significant decreases in the market price of an asset or asset group, significant changes in the extent or manner in which an asset or asset group is being used by the Company or in its physical condition, a significant change in legal factors or in the business climate, a history or forecast of future operating or cash flow losses, significant disposal activity, a significant decline in the Company’s share price, a significant decline in revenues or adverse changes in the economic environment. When indicators of impairment exist, LLA impairment is tested using a two-step process. The Company performs a cash flow recoverability test as the first step, which involves comparing the estimated undiscounted future cash flows for the asset group to the carrying amount of the asset group. If the net cash flows of the asset group exceed its carrying amount, the asset group is not considered to be impaired. If the carrying amount of the asset group exceeds the net cash flows, there is an indication of potential impairment and the second step of the LLA impairment test is performed to measure the impairment amount. The second step involves determining the fair value of the asset group. Fair value is determined using valuation techniques that are in accordance with U.S. GAAP, including the market approach, income approach and cost approach. If the carrying amount of the asset group exceeds its fair value, then the excess represents the maximum amount of potential impairment that will be allocated to the asset group, with the limitation that the carrying value of each asset cannot be reduced to a value lower than that of its fair value. The total impairment amount allocated is recognized as a non-cash impairment loss. Investment in Joint Venture The equity method is used to account for investments in joint ventures and certain other non-controlled entities when the Company has the ability to exercise significant influence over operating and financial policies of the investee, even though the investor holds 50% (joint control) or less of the voting common shares. Under this method, the investment, originally recorded at cost, is adjusted to recognize the Company’s share of net earnings or losses and other changes in equity of the affiliate as they occur, with losses limited to the extent of the Company’s investment in, advances to and commitments to the investee. Goodwill Goodwill is recorded as at the date of the business combination and represents the excess of the purchase price of acquired businesses over the fair value assigned to identifiable assets acquired and liabilities assumed. Goodwill is tested for impairment at the reporting unit level by first performing a qualitative assessment to determine whether it is more likely than not that the fair value of the reporting unit is less than its carrying value. The qualitative assessment considers the following factors: macroeconomic conditions, industry and market considerations, cost factors, overall company financial performance, events affecting the reporting unit and changes in the Company’s fair value. If the reporting unit does not pass the qualitative assessment, the Company carries out a quantitative test for impairment of goodwill. This is done by comparing the fair value of the reporting unit with the carrying value of its net assets. If the fair value of the reporting unit is greater than its carrying value, no impairment results. If the fair value of the reporting unit is less than its carrying value, an impairment loss would be recognized in the Consolidated Statements of Operations in an amount equal to that difference, limited to the total amount of goodwill allocated to that reporting unit. The Company has three reporting units. Deferred Revenue Deferred revenue is comprised of cash collected from customers and billings to customers on contracts in advance of work performed, advance payments negotiated as a contract condition, including billings in excess of costs and estimated earning on uncompleted contracts. The Company records provisions for estimated losses on uncompleted contracts in the period in which such losses become known. The cumulative effects of revisions to contract revenues and estimated completion costs are recorded in the accounting period in which the amounts become evident and can be reasonably estimated. These revisions can include such items as the effects of change orders and claims, warranty claims, liquidated damages or other contractual penalties and adjustments for contract closeout settlements. Revenue Recognition The Company recognizes 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. The following paragraphs describe the specific revenue recognition policies for each of the Company’s significant types of revenue by segment. Licensing segment Under ASC 606, licenses are considered licenses to functional intellectual property. The standard specifically outlines that patents, underlying highly functional items, are considered functional intellectual property (“IP”). Licenses to functional IP are considered satisfied at a point in time (i.e. when the license becomes effective) and all the revenue is recognized at that point in time. Payment is either due immediately or within 30 days. The one exception to this guidance is related to revenue generated from sales or usage-based royalties promised in exchange for a license of IP. Customers generally report their royalty obligations one quarter in arrears and accordingly, the Company estimates the expected royalties to be reported for an accounting period, with a true up to the actual royalties reported in the following financial reporting period. Payment is due upon submission of the royalty report. Intelligent systems segment Contracted Projects The majority of sales of integrated systems are delivered as contracted projects that span a time period of less than 1 year to more than 5 years. Governments and private enterprises control all of the work in progress as intelligent transportation systems are being developed and installed. The Company’s contract types include fixed price and time and materials contracts. Contract revenue includes amounts expected to be received in exchange for the good or services plus any contract amendments that are expected to be received. Payment terms are based on completion of milestones throughout the project life for fixed price contracts and monthly for time and materials projects. Many of these projects have distinct performance obligations typically encompassing one or more of installation, maintenance and warranty. A contract’s transaction price is allocated to each distinct performance obligation using the best estimate of the standalone selling price of each distinct good or service in the contract. The primary method used to estimate standalone selling price is the expected cost plus margin approach. Revenue is recognized when or as the performance obligation is satisfied. Revenue for fixed price contracts is recognized over time using the cost-to-cost input method. Because control is transferred over time, revenue is recognized based on the extent of progress towards completion of the performance obligation. The company reviews and updates the contract related estimates regularly. Determining the contract costs and estimates to complete requires significant judgment. Adjustments are recognized in profit on contracts under the cumulative catch-up method in the period the adjustment is identified. If the Company anticipates the estimated remaining costs to completion will exceed the value allocated to the performance obligation, the resulting loss will be recognized immediately. For time and materials contracts, labor and material rates are established within the contract. Revenues from time and materials contracts are recognized progressively on the basis of costs incurred during the period plus the estimated margin earned. Maintenance Revenue Maintenance revenue from the Intelligent systems segment are considered recurring revenues. These service contracts are typically time and materials, but some are fixed price. Revenues are earned similar to contracted projects discussed above. Services are billed on a monthly basis and collected shortly thereafter. Product Sales Product sales revenue is recognized when control transfers to the customer which depends on the individual terms which can vary between when the product leaves the Company’s warehouse and when it is received at the customer’s warehouse. For some international shipments, when the buyer has no right of return, transfer occurs upon loading the goods onto the relevant carrier at the port of the seller. Customers are billed when transfer of control occurs and payments are typically due within 30 days. Enterprise Software Segment Software Licenses The Enterprise software segment provides bolt-on software products to enhance enterprise resource planning (“ERP”) -based asset maintenance systems. These software licenses contain up to five separate performance obligations: the license, implementation services, training services, post-contract customer support (“PCS”) and enhancement of software. Customers obtain access to licenses through online software and each additional component is added incrementally at the stand-alone market price which represents the price allocated to each performance obligation. Payment for licenses and services is received prior to delivery of product code for software or software keys for PCS. When selling the licensed software, the Company is providing the customer with the right to use its intellectual property and does not provide significant modifications or updates therefore revenue is recognized at the point in time when the customer gains control of the license, typically at contract inception. Implementation and training services, PCS and enhancement of software are recognized over time based on time lapsed as this best represents the value transferred to the customer based on the specifications for each within the contract. Research and Development Research costs are charged to expense in the periods in which they are incurred. Software development costs are deferred and amortized when technological feasibility has been established, or otherwise are expensed as incurred. Warranties The Company records the estimated costs of product warranties at the time revenue is recognized. Warranty obligation arises from the Company having to replace goods and/or services that have failed to meet required customer specifications due to breakdown or error related to product or workmanship. The Company’s warranty obligations are affected by product failure rates, differences in warranty periods, regulatory developments with respect to warranty obligations in the countries in which the Company carries on business, freight expense and material usage and other related repair costs. The Company’s estimates of costs are based upon historical experience and expectations of future return rates and unit warranty repair costs. If the Company experiences increased or decreased warranty activity or increased or decreased costs associated with servicing those obligations, revisions to the estimated warranty liability would be recognized in the reporting period when such revisions are made. Capitalized Contract Costs As part of obtaining contacts with certain customers, the Company incurs upfront costs such as sales commissions. The Company expenses these sales commissions when incurred because the amortization period generally would have been one year or less. Sales commissions are recorded in selling, general and administrative expenses in the Consolidated Statements of Operations. Advertising Costs The Company expenses all advertising costs as incurred. These costs are included in selling, general and administrative costs. Financing Costs Financing costs are comprised of borrowing cost to the extent applicable, foreign currency gains and losses on the translation of foreign-denominated borrowings, unwinding of the discount on provisions, changes in the fair value of financial assets and financial liabilities at fair value through profit or loss and gains and losses on hedging instruments recognized through profit and loss, if any. Leases Operating lease payments are recognized as selling, general and administrative expenses on a straight‑line basis over the lease term. If lease incentives are received to enter into operating leases, such incentives are recognized as a liability. The aggregate benefit of incentives is recognized as a reduction of rental expense on a straight‑line basis, except where another systematic basis is more representative of the time pattern in which economic benefits from the leased asset are consumed. Computation of Earnings (Loss) Per Share Basic earnings/loss per share is computed using the weighted average number of common shares outstanding during the year. Diluted earnings/loss per share are computed using the treasury stock method. Business Segment Information ASC Topic 280, “Segment Reporting” (“Topic 280”), establishes standards for reporting, by public business enterprises, information about operating segments, products and services, geographic areas and major customers. The method of determining what information to report under Topic 280, is based on the way that an entity organizes operating segments for making operational decisions and how the entity’s management and chief operating decision maker assess an entity’s financial performance. Income Taxes, Deferred Taxes and Investment Tax Credits The Company uses the liability method of accounting for income taxes. Deferred income tax assets and liabilities are determined based on the difference between the accounting and tax bases of the assets and liabilities and measured using the enacted tax rates that are expected to be in effect when the differences are estimated to be reversed. In assessing the realizability of deferred income tax assets, management considers whether it is more likely than not that some portion or all of the deferred income tax assets will not be realized. The realization of deferred income tax assets is dependent upon the generation of sufficient future taxable income during the periods prior to the expiration of the associated tax attributes. The Company is also engaged in scientific research and experimental development giving rise to investment tax credits that may be available to reduce future taxes payable in certain jurisdictions. In calculating income taxes and investment tax credits, consideration is given to factors such as current and future tax rates in the different jurisdictions, non-deductible expenses, qualifying expenditures and changes in tax law. In addition, management makes judgments on the ability of the Company to realize deferred taxes and investment tax credits reported as assets based on their estimations of amounts and timing of future taxable income and future cash flows in the related jurisdiction. Future Accounting Pronouncements Leases In February 2016, the FASB issued ASU 2016-2, “Leases” and issued subsequent amendments to the initial guidance during 2018, collectively referred to as “Topic 842.” The guidance requires companies to include lease obligations in their balance sheets, including a dual approach for lessee accounting under which a lessee would account for leases as finance leases or operating leases. Both finance leases and operating leases will result in the lessee recognizing a right-of-use (“ROU”) asset and a corresponding lease liability. For finance leases t

New Accounting Pronouncements And Changes In Accounting Principles [Abstract]
Adoption of Accounting Standards	3. ADOPTION OF ACCOUNTING STANDARDS ASU 2017-04 , Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment In January 2017, the FASB issued ASU No. 2017-04 “Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment” which simplifies the subsequent measurement of goodwill and eliminates Step 2 from the goodwill impairment test. The standard is effective for annual periods beginning after December 15, 2019 but the Company opted for early adoption for the goodwill impairment test that was completed as of December 31, 2018. ASU 2016-16 Intra-entity Transfers of Assets Other Than Inventory In October 2016, the FASB issued ASU 2016-16 “Income taxes on intra-entity transfers of assets other than inventory” to improve the accounting on income taxes on intra-entity transfers. The ASU requires that an entity recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs, rather than defer the income tax effect under previous guidance. The Company adopted this ASU on a modified retrospective basis in the first quarter of 2018. The cumulative effect of the adoption is an increase to shareholders’ equity of $2.9 million due to the adjustment to the accumulated deficit. ASU 2014-09 Revenue from Contracts with Customers In May 2014, the FASB issued Accounting Standards Update No. 2014-09 (ASU 2014-09) “Revenue from Contracts with Customers” (ASC 606). ASC 606 supersedes the revenue recognition requirements in ASC 605 “Revenue Recognition,” 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 which the entity expects to be entitled to in exchange for those goods or services. The Company adopted ASC 606 using the modified retrospective method applied to those contracts that were not yet complete as of January 1, 2018. Results for reporting periods beginning after January 1, 2018 are presented under Topic ASC 606, while prior period amounts are not adjusted and continue to be reported in accordance with our historic accounting under ASC 605. With respect to its Licensing segment, under the Topic 605, licensing companies report revenue to the Company from per-unit royalty-based arrangements one quarter in arrears, resulting in revenue being recognized on the same basis. Under the new guidance, the Company estimates the per-unit royalty-based revenue each period. The new standard also significantly impacts the timing of revenue recognition associated with its fixed fee “right to use” arrangements where under the new standard the Company recognizes license revenues at the time of signing a license agreement (upfront) rather than recognizing revenue over the term of the arrangement. With respect to its Intelligent systems segment, for the majority of its long-term contracts, the Company recognizes revenue and earnings over time as the work progresses because of the continuous transfer of control to the customer. The adoption of this standard has impacted revenue recognition in relation to the allocation of contract revenues between installations, maintenance agreements and warranty on some long-term fixed price contracts. The adoption of ASC 606 does not have a significant impact on the amount and timing of how revenue is recognized within the Enterprise software segment. The Company opted to use the following practical expedients: 1. For contracts that were modified before implementation, the Company has considered the aggregate effect of all modifications when identifying the satisfied and unsatisfied performance obligations, determining the transaction price and allocating the transaction price to satisfied and unsatisfied performance obligations; 2. The Company will not adjust the promised amount of consideration for the effects of a significant financing component if the entity expects, at contract inception, that the period between when the entity transfers a promised good or service to the customer and when the customer pays for that good or service will be one year or less. The cumulative effect of the changes made to the Company’s consolidated January 1, 2018 balance sheet for the adoption of ASU 2016-16 and ASU 2014-09 were as follows: Adjustments arising from implementation of ASU 2014-09 Balances as at December 31, 2017 ASU 2016-16 Licensing Intelligent Systems Balances as at January 1, 2018 Assets Unbilled revenue $ 3,045 $ - $ 6,376 $ (565 ) $ 8,856 Deferred income tax assets 20,195 2,949 - 150 23,294 Liabilities Deferred income tax liabilities 7,291 - 1,689 - 8,980 Equity Deficit (206,939 ) 2,949 4,687 (415 ) (199,718 ) The following tables disclose the impact of adoption, by segment, on the Company’s consolidated statement of operations for the twelve months ended December 31, 2018: For the year ended December 31, 2018 Adjustments arising from implementation of ASU 2014-09 As reported Licensing Intelligent Systems Balances without ASU 2014-09 Revenues License $ 23,544 $ 5,563 $ - $ 29,107 Systems 29,252 - (272 ) 28,980 Services 2,629 - - 2,629 Recurring 21,976 230 141 22,347 Costs and expenses Deferred income tax expense (recovery) (8,345 ) 1,535 (34 ) (6,844 ) Net loss (49,120 ) 4,258 (97 ) (44,959 ) The following table discloses the impact of adoption, by segment, on the Company’s consolidated balance sheet as at December 31, 2018: Adjustments arising from implementation of ASU 2014-09 As reported Licensing Intelligent Systems Balances without ASU 2014-09 Assets Unbilled revenue $ 3,990 $ (584 ) $ 433 $ 3,839 Deferred income tax assets 27,141 - (115 ) $ 27,026 Liabilities Deferred income tax liabilities 4,337 (155 ) - 4,182 Equity Deficit (253,443 ) (429 ) 318 (253,554 ) During the first quarter of 2018, the Company also adopted ASU 2016-01 Financial Instruments – Recognition and Measurement of Financial Assets and Financial Liabilities, ASU 2016-15 Statement of Cash Flows – Classification of Certain Cash Receipts and Cash Payments, ASU 2017-01 Business Combinations (Topic 805) – Clarifying the Definition of a Business and ASU 2017-04 – Intangibles – Goodwill and Other – Simplifying the Test for Goodwill Impairment. The adoption of these standards did not have a material impact on the consolidated financial statements or the related note disclosures.

The Company tests goodwill for impairment annually in the fourth quarter of each year using data as of December 31 of that year. The Company opted to complete the first step under ASC350 by comparing the carrying value of each reporting unit with its fair value. The Company determines fair value for each of the reporting units using the market approach, when available and appropriate, or the income approach, or a combination of both. The Company assesses the valuation methodology based upon the relevance and availability of the data at the time it performs the valuation. If multiple valuation methodologies are used, the results are weighted appropriately. Valuations using the market approach are derived from metrics of publicly traded companies or historically completed transactions of comparable businesses. The selection of comparable businesses is based on the markets in which the reporting units operate giving consideration to risk profiles, size, geography and diversity of products and services. A market approach is limited to reporting units for which there are publicly traded companies that have characteristics similar to the Company’s businesses. Under the income approach, fair value is determined based on the present value of estimated future cash flows, discounted at an appropriate risk-adjusted rate. The Company uses its internal forecasts to estimate future cash flows and include an estimate of long-term future growth rates based on its most recent views of the long-term outlook for each business. Actual results may differ from those assumed in these forecasts. The Company derives its discount rates using a capital asset pricing model and by analyzing published rates for industries relevant to its reporting units to estimate the cost of equity financing. The Company uses discount rates that are commensurate with the risks and uncertainty inherent in the respective businesses and in its internally developed forecasts. Discount rates used in these reporting unit valuations ranged from 14.5% to 25.0%. Based on the results of quantitative testing, the fair values of each of the reporting units exceeded their carrying values except for the Intelligent Systems reporting unit which is consistent with our Intelligent Systems segment. Accordingly, in the fourth quarter, the Company recorded a non-cash impairment loss of $16,066. The impairment loss included $246 of goodwill recorded as a result of the iCOMS acquisition which had been allocated to our Intelligent Systems reporting unit. After the impairment loss, there is no remaining goodwill associated with the Intelligent Systems reporting unit and $25,303 related to the Company’s Licensing and Enterprise Software reporting units at December 31, 2018. Estimating the fair value of reporting units requires the use of estimates and significant judgments that are based on a number of factors including actual operating results. It is reasonably possible that the judgments and estimates described above could change in future periods.

As at December 31, 2018, the Company had options to purchase up to 6,840,475 Common Shares outstanding. Upon adoption of the Equity Incentive Plan, all options outstanding under the Option Plan are now governed by the Equity Incentive Plan.

Quarterhill maintains the newly adopted Equity Incentive Plan (replacing the Option Plan and the DSU Plan) and a Restricted Share Unit (“RSU”) Plan for its directors, employees and consultants. The current RSU Plan calls for settlement only in cash. During the year ended December 31, 2018, the Company granted options to purchase 3,854,626 Common Shares at exercise prices ranging from CDN$2.02 to CDN$2.38 with weighted average fair value of CDN$0.81. The Company used the Black-Scholes model for estimating the fair value of options granted with the following weighted average assumptions for the options granted in 2018. 2018 Risk free rate 2.24 % Volatility 48 % Expected option life (in years) 6 Forfeiture rate 18.13 % During the year ended December 31, 2017, the Company granted two sets of performance-based options with grant date at fair value of CDN$1.106 and CDN$1.0175, respectively. These performance-based options will vest, if at all, over a three year period. Each tranche of options will vest if at any time after the first, second and third years, certain specified share price targets are achieved for a period of at least 30 consecutive days. The Company estimates the fair value of the performance based options using a Monte Carlo simulation model. The following assumptions were used during the year ended December 31, 2017: May Grant June Grant Number of options granted 1,299,072 650,000 Stock price CDN $ 2.16 $ 1.89 Implied volatility 55 % 60 % Risk free rate 1.43 % 1.40 % Options Outstanding Exercisable Options Number of Options Price Range (CDN) Weighted Average Exercise Price (CDN) Number Weighted Average Exercise Price (CDN) December 31, 2016 5,985,454 $ 2.84 $ 5.66 $ 4.78 5,617,312 $ 4.89 Granted 1,949,072 1.89 2.16 2.07 Forfeited (108,967 ) 3.39 5.34 4.26 Expired (2,486,000 ) 5.34 5.66 5.48 December 31, 2017 5,339,559 $ 1.89 $ 5.05 $ 3.48 3,219,503 $ 4.36 Granted 3,854,626 2.02 2.38 2.26 Forfeited (1,063,334 ) 1.89 2.16 2.10 Expired (1,290,376 ) 1.89 5.05 4.75 December 31, 2018 6,840,475 $ 1.89 $ 4.37 $ 2.77 2,231,285 $ 3.85 The weighted average fair value per option granted during the year ended December 31, 2018 was CDN$0.81 (2017 – $ 1.08) The intrinsic value of the exercisable options was $nil as at December 31, 2018 (2017 –$nil). The total fair value of options vested was CDN$150 for the year ended December 31, 2018 (2017 – CDN$150). As at December 31, 2018, there was CDN$1.9 million of total unrecognized stock-based compensation cost, net of expected forfeitures, related to unvested stock-based compensation arrangements granted under the stock option plan. This cost is expected to be recognized over a weighted average period of 2.1 years. Details of the outstanding options at December 31, 2018 are as follows: Range of Exercise Prices (CDN) Outstanding Options at December 31, 2018 Remaining Term of Options in Years Weighted Average Exercise Price (CDN) Exercisable Options at December 31, 2018 Weighted Average Exercise Price (CDN) $ 1.89 $ 1.99 300,000 4.42 $ 1.89 100,000 $ 1.89 2.00 2.99 4,570,175 5.05 2.28 164,318 2.84 3.00 3.99 707,000 0.84 3.43 703,667 3.43 4.00 4.37 1,263,300 0.21 5.05 1,263,300 4.36 $ 1.89 $ 4.37 6,840,475 2.79 $ 2.77 2,231,285 $ 3.85 Stock-based compensation expense for the year ended December 31, 2018 was $468 (2017 - $663).

Under the RSU plan, units are settled in cash based on the market value of Quarterhill’s common shares on the dates when the RSUs vest. The accrued liability and related expense for the RSUs are adjusted to reflect the market value of the common shares at each balance sheet date. The liability recorded in respect of the vested RSUs was $824 as at December 31, 2018 (2017 - $2,105). The change in the liability is recorded as compensation expense. RSU activity for the years ended December 31, 2018 and 2017 was as follows: Number December 31, 2016 2,712,420 Granted 3,826,851 Settled (2,475,623 ) Forfeited (128,599 ) December 31, 2017 3,935,049 Granted 1,977,335 Settled (3,024,277 ) Forfeited (619,764 ) December 31, 2018 2,268,343 During the year ended December 31, 2018, 619,764 RSUs (2017 – 128,599) were forfeited as they related to former employees. g) Per Share Amounts The weighted average number of common shares outstanding used in the basic and diluted earnings per share computation was: December 31, December 31, As at 2018 2017 Basic weighted average common shares outstanding 118,768,728 118,607,569 Effect of stock options - 8,114 Diluted weighted average common shares outstanding 118,768,728 118,615,683 For the year ended December 31, 2018, the effect of stock options totaling 6,840,475 were anti-dilutive (2017 – 5,331,445).

The aggregate minimum annual lease payments under these agreements are as follows: Amount 2019 $ 1,260 2020 1,131 2021 1,089 2022 974 2023 606 2024 and thereafter - $ 5,059 b) Contingent Consideration Obligation In connection with the acquisition of VIZIYA on May 4, 2017, the Company agreed to future additional payments to the former owners of VIZIYA, based on achieving future earnings targets (as defined in the purchase agreements) generated as a result of operations of VIZIYA. An estimated fair value measurement of the contingent consideration obligation was determined at the date of acquisition of $6,450 using the most current information available as at May 4, 2017. The estimate was calculated using the Monte Carlo simulations model. On December 31, 2017, the Company updated its fair value measurement estimate using the same model with the most current information available. As a result, the contingent consideration obligation decreased by $1,976 to a revised estimate of $4,474. On December 31, 2018, the Company further updated its fair value measurement estimate based on management’s forecast of operations through to July 31, 2019 and determined the fair value of the contingent consideration obligation decreased by $3,545 to $929 as at December 31, 2018. The Company will continue to estimate the fair value measurement of the contingent consideration until July 31, 2019 with any changes in that fair value included in Special charges in the consolidated statements of operations.

Management has assigned probabilities to the Company’s expected future taxable income based on significant risk factors, sensitivity analysis and timing of non-capital tax losses. However, the amount of the deferred income tax asset considered realizable could change materially in the near term, based on future taxable income during the carryforward period. The valuation allowance consists of $2,851 in Canada, $10,807 in the U.S., $1,179 in India and $309 elsewhere. As at December 31, 2018, the Company had unused non-capital tax losses of approximately $115,836 (2017 - $67,883) that are due to expire as follows: Expiry SRED pool Canadian tax losses US tax losses Other jurisdictions Consolidated tax losses 2019 $ - $ - $ - $ - $ - 2020 - - - 2,370 2,370 2021 - - 203 240 443 2022 - - 603 287 890 2023 - - 616 18 634 2024 - - - 228 228 2025 - - - 57 57 2026 - - - 1 1 2027 - 866 1 458 1,325 2028 - - - - - 2029 - - 9 - 9 2030 - - 414 - 414 2031 - - 3,026 - 3,026 2032 - - 2,179 - 2,179 2033 - 4,934 4,807 - 9,741 2034 - 4,099 7,629 - 11,728 2035 - 2,021 4,443 247 6,711 2036 - 5,714 1,525 69 7,308 2037 - 22,216 8,452 797 31,465 2038 - 32,289 - 312 32,601 Indefinite 23,889 - 3,247 1,459 4,706 $ 23,889 $ 72,139 $ 37,154 $ 6,543 $ 115,836 The Company also has investment tax credits of $3,976 that expire in various amounts from 2019 to 2032. Investment tax credits, which are earned as a result of qualifying scientific research and experimental development expenditures, are recognized and applied to reduce income tax expense in the year in which the expenditures are made and their realization is reasonably assured. The Company had no uncertain income tax positions as at December 31, 2018.

Segment Reporting [Abstract]
Segment Reporting	17. SEGMENT REPORTING The Company reports segment information based on the “management” approach. The management approach designates the internal reporting used by the chief operating decision maker (“CODM”) for making decisions and assessing performance as a source of the Company’s reportable operating segments. During the year ended December 31, 2017, the Company acquired new businesses and, as a result, the CODM, who was the Interim Chief Executive Officer of the Company, began making decisions and assessing the performance of the Company using three operating segments comprised of these reporting units, whereas the Company was previously a single operating segment. During the year ended December 31, 2018, the Chief Executive Officer of the Company continued to make decisions and assess the performance of the Company using the same three operating segments or reporting units. Licensing – The Licensing segment includes companies that count licensing as their principal business activity. Current patent portfolios held by this segment include patents relating to 3D television technologies, automotive headlight assemblies, phased loop semiconductor Licensing, microcontrollers applicable to safety-critical aerospace, semiconductor manufacturing and packaging technologies, medical, industrial and automotive applications, computer gaming, medical stent technologies, intelligent personal assistant technologies, CMOS image sensors, enhanced image processing, streaming video technologies, building automation, non-volatile Flash memory, other memory technologies, semiconductor clocking technologies, smart meter monitoring, LED lighting technologies and many other technologies. Intelligent systems – The Intelligent systems segment includes companies providing systems and services focused on the interconnection of devices for mobile applications. The first investment in this segment is IRD, one of the world’s leading providers of integrated systems and solutions for the global ITS industry. The ITS industry is focused on improving the Intelligent systems, enhancing the safety, increasing the efficiency and reducing the environmental impact of highway and roadway transportation systems. IRD has a network of direct and independent operations and relationships in strategic geographic regions to identify and pursue ITS opportunities around the world. Enterprise software – The Company considers businesses focused on operations optimization, predictive maintenance, inventory optimization and health and safety in production environments as operating in a “Enterprise software” environment and classifies its related investments in the Enterprise software segment. The Company’s first investment in this segment is VIZIYA based in Hamilton, Ontario, Canada, a software company providing Enterprise Asset Management software solutions to asset intensive industries worldwide through its presence in Australia, Europe, the Middle East and South Africa. VIZIYA has created software solutions that enhance each step of a customer’s work management process, to help customers measure the results of their initiatives, particularly focused on asset criticality, urgency and compliance to ensure customers implement their asset strategies. The following table reconciles the Adjusted EBITDA measure which is used in the evaluation of the performance of each segment to Net income. The Company used Adjusted EBITDA as its principle performance measure during the years ended December 31, 2018 and 2017.

During the year ended December 31, 2018, there were no major customers identified (2017: one). Remaining performance obligations As at December 31, 2018 the amount of transaction price allocated to remaining performance obligations was $25,833. The Company expects to recognize approximately 68% of this balance as revenue in 2019, 17% in 2020 and 15% thereafter.

Financial Risk Management

Financial Risk Management [Abstract]
Financial Risk Management	18. FINANCIAL RISK MANAGEMENT Credit Risk Credit risk is the risk of financial loss to the Company if a licensee or counter-party to a financial instrument fails to meet its contractual obligations. Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents, short-term investments, accounts receivable, and foreign exchange forward contracts. The Company’s cash and cash equivalents and short-term investments consist primarily of deposit investments that are held primarily with Canadian chartered banks. Management does not expect any counter-parties to fail to meet their obligations. The Company’s loan receivable is a term loan facility which is collateralized by a general security agreement. Management does not expect the borrower to fail to meet its obligations. The Company’s exposure to credit risk with its accounts receivable from customers are influenced mainly by the individual characteristics of each customer. The Company’s customers are for the most part, large multinational companies or government organizations which do not have a history of non-payment. Credit risk from accounts receivable encompasses the default risk of the Company’s customers. Prior to entering into transactions with new customers, the Company assesses the risk of default associated with the particular customer. In addition, on an ongoing basis, management monitors the level of accounts receivable attributable to each customer and the length of time taken for amounts to be settled and where necessary, takes appropriate action to follow up on those balances considered overdue. The Company has had no significant bad debts for any periods presented. No customer individually accounted for more than 10% of revenue for the year ended December 31, 2018 (2017 – one customer individually accounted for 55%). Management does not believe that there is significant credit risk arising from any of the Company’s customers for which revenue has been recognized. However, should one of the Company’s major customers be unable to settle amounts due, there would be an impact on the results of the Company. The maximum exposure to loss arising from accounts receivable is equal to their total carrying amounts. At December 31, 2018, two customers individually accounted for 14%and 12% of the accounts receivable balance outstanding. As at December 31, 2017, one customer accounted for 23% of the accounts receivable balance outstanding. The following table provides an aging analysis of trade accounts receivable. The age of an invoice does not necessarily indicate an account is past due as many contracts for system revenue require the successful completion of system testing and acceptance. December 31, December 31, As at 2018 2017 Current $ 769 $ 12,000 1 - 30 days 2,885 2,909 31 - 60 days 2,146 1,098 61 - 90 days 3,193 1,114 91 days and over 2,677 2,598 Less allowance for doubtful accounts (858 ) (421 ) Accounts receivable 10,812 19,298 Long-term accounts receivable 415 - Total accounts receivable $ 11,227 $ 19,298 None of the amounts outstanding have been challenged by the respective counterparties and the Company continues to conduct business with them on an ongoing basis. Accordingly, management has no reason to believe that this balance is not fully collectable in the future. The Company reviews financial assets on an ongoing basis with the objective of identifying potential matters which could delay the collection of funds at an early stage. Once items are identified as being past due, contact is made with the respective customer to determine the reason for the delay in payment and to establish an agreement to rectify the breach of contractual terms. At December 31, 2018, the Company had a provision for doubtful accounts of $858 Liquidity Risk Liquidity risk is the risk that the Company will not be able to meet its financial obligations as they fall due. The Company’s objective in managing liquidity risk is to ensure that it has sufficient liquidity available to meet its liabilities when due. At December 31, 2018, the Company had cash and cash equivalents and short-term investments of $67,268, accounts receivable of $11,227 and various credit facilities as outlined in Note 13 available to meet its obligations. In addition, Export Development Canada has provided a guarantee to IRD’s additional credit facility of $2.0 million for the support of performance guarantees provided by IRD’s subsidiaries. At December 31, 2018 performance guarantees totaling $nil (December 31, 2017 - $31) were outstanding under this credit facility. Market Risk Market risk is the risk to the Company that the fair value of future cash flows from its financial instruments will fluctuate due to changes in interest rates and foreign currency exchange rates. Market risk arises as a result of the Company generating revenues in foreign currencies. Interest Rate Risk The financial instruments that expose the Company to interest rate risk are its cash and cash equivalents, short-term investments, bank indebtedness and long-term debt. The Company’s objectives of managing its cash and cash equivalents and short-term investments are to ensure sufficient funds are maintained on hand at all times to meet day to day requirements and to place any amounts which are considered in excess of day to day requirements on short-term deposit with the Company’s banks so that they earn interest. When placing amounts of cash and cash equivalents into short-term investments, the Company only places investments with Canadian chartered banks and ensures that access to the amounts placed can be obtained on short-notice. A one percent increase/decrease in interest rates would not have resulted in a material increase/decrease in interest income/expense during the year ended December 31, 2018. Currency Risk A portion of Quarterhill’s revenues and operating expenses are denominated in Canadian dollars, Indian rupee, Chilean peso, Euro, Australian dollar and Chinese Yuan. Because the Company reports its results of operations in U.S. dollars, Quarterhill’s operating results are subject to changes in the exchange rate of the foreign currencies (primarily Canadian dollar) relative to the U.S. dollar. Any decrease in the value of the Canadian dollar relative to the U.S. dollar has an unfavorable impact on Canadian dollar denominated revenues and a favorable impact on Canadian dollar denominated operating expenses. Approximately 7.9% of the Company’s cash and cash equivalents and short-term investments are denominated in Canadian dollars and are subject to changes in the exchange rate of the Canadian dollar relative to the U.S. dollar. The following table illustrates the Company’s exposure to exchange risk and the pre-tax effects on earnings and other comprehensive income (“OCI”) of a 5% decrease in the U.S. dollar in comparison to other relevant foreign currency. This analysis assumes all other variables remain constant. Foreign Currency Exposure Foreign Currency exchange risk 5% decrease in US$ December 31, 2018 Income OCI Net asset: Canadian dollar (2,549 ) 37 (165 ) Indian rupee 101 - 5 Chilean peso 602 - 30 Euro (411 ) 2 (23 ) Australian dollar 597 - 30 Chinese Yuan 3,822 - 191 The Company may manage the risk associated with foreign exchange rate fluctuations by, from time to time, entering into foreign exchange forward contracts and engaging in other hedging strategies. To the extent that Quarterhill engages in risk management activities related to foreign exchange rates, it may be subject to credit risks associated with the counterparties with whom it contracts. The Company’s objective in obtaining foreign exchange forward contracts is to manage its risk and exposure to currency rate fluctuations related primarily to future cash inflows and outflows of Canadian dollars. The Company does not use foreign exchange forward contracts for speculative or trading purposes. For the year and as at December 31, 2018, the Company did not hold any foreign exchange forward contracts.

Business Acquisition And Restructuring Costs [Abstract]
Special Charges	21. SPECIAL CHARGES Special charges within the consolidated statements of operations include costs and recoveries that relate to certain restructuring initiatives that we have undertaken from time to time, acquisition-related costs and recoveries and other charges. Fiscal 2018 Restructuring Program During Fiscal 2018 we began to implement restructuring activities to streamline our operations (collectively the “Fiscal 2018 Restructuring Program”). The Fiscal 2018 Restructuring Program charges relate to workforce reductions including retiring allowances related to certain individuals and facility consolidations. As of December 31, 2018, we accrued costs to be of approximately $6,233, of which $3,020 has been paid. The restructuring accruals require management to make certain judgments and estimates regarding the amount and timing of restructuring charges or recoveries. Our estimated liability could change subsequent to its recognition, requiring adjustments to the expense and the liability recorded. On a quarterly basis, we conduct an evaluation of the related liabilities and expenses and revise our assumptions and estimates as appropriate. A reconciliation of the beginning and ending restructuring program liability for the year ended December 31, 2018 is shown in the table below. Acquisition related costs including retention payments In connection with the acquisition of VIZIYA, the Company has provided the employees of VIZIYA with a retention plan covering the period from the date of acquisition through to June 30, 2021. Under this retention plan, assuming all present employees of VIZIYA remain employed through the retention period, the Company will pay approximately $1,753 in total retention payments. The first payment, amounting to $303, was made in December 2018. Contingent Consideration Obligation The contingent consideration obligation relates to share and cash earn-out payments which will be made if certain earning targets are met by VIZIYA by July 31, 2019. The fair value estimate for contingent consideration obligation is discussed in Note 15. Adjustments to the fair value measurement of the contingent consideration obligation are recorded as Special charges.

Significant Accounting Polici_2

Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2018
Basis of Presentation	Basis of Presentation These consolidated financial statements are presented in accordance with generally accepted accounting principles in the United States (“U.S. GAAP”). The consolidated financial statements were prepared on a going concern basis, under the historical cost convention except for certain financial instruments that are measured at fair value on a recurring basis, as explained in the accounting policies below. Historical cost is measured as the fair value of the consideration provided in exchange for goods and services on the date of the transaction. All financial information is presented in thousands of U.S. dollars, except as otherwise indicated.
Basis of Consolidation	Basis of Consolidation These consolidated financial statements include the accounts of Quarterhill and its wholly-owned subsidiaries. Quarterhill also holds, through one of its subsidiaries, a 50% joint venture ownership interest in Xuzhou-PAT Control Technologies Limited (“XPCT”) which is accounted for using the equity method. These consolidated financial statements include only the Company’s net investment and equity in earnings of the joint venture. All inter-company transactions and balances have been eliminated in these consolidated financial statements.
Estimates and Assumptions	Estimates and Assumptions The preparation of 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 disclosure of contingent assets and liabilities at the dates of the financial statements and the reported amounts of revenues and expenses during the years. Actual results could differ from those estimates. The significant accounting policies contained herein include estimates and assumptions with respect to the determination of fair values of tangible and intangible assets acquired in business combinations, best estimate of stage of completion of contracted projects, identification of distinct performance obligations, in contracts with customers and the related stand alone selling prices, recoverability of financial assets and equity investments, income tax and the recoverability of deferred tax assets, determination of indicators of impairment and related impairment assessments.
Business Combinations	Business Combinations The Company applies the provisions of the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 805, “Business Combinations”, in the accounting for its acquisitions. This requires the Company to recognize separately from goodwill the assets acquired and the liabilities assumed at their acquisition date fair values. Goodwill as of the acquisition date is measured as the excess of consideration transferred over the net of the acquisition date fair values of the assets acquired and the liabilities assumed. While the Company uses its best estimates and assumptions to accurately value assets acquired and liabilities assumed at their fair values, including contingent consideration where applicable, these estimates are inherently uncertain and subject to refinement, particularly since these assumptions and estimates are based in part, on historical experience and information obtained from the management of the acquired companies. As a result, during the measurement period, which may be up to one year from the acquisition date, the Company may record adjustments to the assets acquired and liabilities assumed with the corresponding offset to goodwill in the period identified. Furthermore, when valuing certain intangible assets that the Company has acquired, critical estimates may be made relating to, but not limited to: (i) future expected cash flows from customer relationships, software license sales, support agreements, consulting agreements and other customer contracts; (ii) the acquired entity’s brand and competitive position, as well as assumptions about the period of time that the acquired brand will continue to be used in the combined Company’s product portfolio; and (iii) discount rates. Upon the conclusion of the measurement period or final determination of the values of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments would be recorded to the Company’s consolidated statements of operations, on a cumulative basis, in the period in which the adjustment is determined. For a given acquisition, the Company identifies certain pre-acquisition contingencies as of the acquisition date and may extend its review and evaluation of these pre-acquisition contingencies throughout the measurement period to obtain sufficient information to assess whether the Company includes these contingencies as a part of the purchase price allocation and, if so, to determine the estimated amounts. If the Company determines that a pre-acquisition contingency (non-income tax related) is probable in nature and estimable as of the acquisition date, then it will record its best estimate for such a contingency as a part of the preliminary purchase price allocation. The Company continues to gather information and evaluates any pre-acquisition contingencies throughout the measurement period and makes adjustments as necessary either directly through the purchase price allocation or in its results of operations. Uncertain tax positions and tax related valuation allowances assumed in connection with a business combination are initially estimated as of the acquisition date. The Company reviews these items during the measurement period as the Company continues to actively seek and collect information relating to facts and circumstances that existed at the acquisition date. Changes to these uncertain tax positions and tax related valuation allowances made subsequent to the measurement period, or if they relate to facts and circumstances that did not exist at the acquisition date, are recorded in the Company’s provision for income taxes in the consolidated statements of operations.
Fair Value Measurement of Financial Instruments	Fair Value Measurement of Financial Instruments The Company uses various valuation techniques and assumptions when measuring fair value of its financial assets and financial liabilities. The Company utilizes market data or assumptions that market participants would use in pricing the asset or liability, including assumptions about risk and the risks inherent in the inputs to the valuation technique. The accounting standard establishes a hierarchy that prioritizes fair value measurements based on the types of input used for the various valuation techniques (market approach, income approach and cost approach). The levels of the hierarchy are described below: Level 1 Inputs — Level 1 includes financial instruments for which quoted market prices for identical instruments are available in active markets. Level 2 Inputs — Level 2 includes financial instruments for which there are inputs other than quoted prices included within Level 1 that are observable for the instrument such as quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets with insufficient volume or infrequent transactions (less active markets) or model-driven valuations in which significant inputs are observable or can be derived principally from, or corroborated by, observable market data, including market interest rate curves, referenced credit spreads and pre-payment rates. Level 3 Inputs — Level 3 includes financial instruments for which fair value is derived from valuation techniques including pricing models and discounted cash flow models in which one or more significant inputs are unobservable, including the Company’s own assumptions. The pricing models incorporate transaction details such as contractual terms, maturity and, in certain instances, timing and amount of future cash flows, as well as assumptions related to liquidity and credit valuation adjustments of marketplace participants. The following methods and assumptions were used to estimate the fair value of each class of financial instruments for which it is practicable to estimate that value. Patent finance obligations: The fair values are estimated based on the quoted market prices for those or similar instruments or on the current rates offered to the Company for debt of similar terms. Derivative financial instruments: The fair value of embedded derivatives is measured using a market approach, based on the difference between the quoted forward exchange rate as of the contract date and quoted forward exchange rate as of the reporting date. The fair value of forward exchange contracts is determined using the quoted forward exchange rates at the reporting date. Contingent considerations: Contingent consideration is carried at fair value which is calculated using management estimates or, where appropriate, a Monte Carlo simulation model. Long-term debt: The fair value is estimated based on the quoted market prices for those or similar instruments or on the current rates offered to the Company for debt of similar terms. The carrying amount of the Company’s other financial assets and liabilities, including cash, accounts receivable, and accounts payable and accrued liabilities approximate their fair value due to the short-term maturity of these items. The fair value of the bank indebtedness and long-term debt approximate the carrying amount since these debt instruments all have floating interest rates.
Derivatives	Derivatives The Company uses derivative financial instruments to reduce exposure to fluctuation in foreign currency exchange rates. The Company may enter into foreign exchange contracts to hedge anticipated cash flows denominated in a foreign currency. The Company has elected not to apply hedge accounting to derivative contracts; as such, these derivative financial instruments are recorded at fair market value on a recurring basis, with subsequent changes in fair value recorded in other income (expense) during the period of change. Derivatives are carried at fair value and are reported as assets when they have a positive fair value and as liabilities when they have a negative fair value. Derivatives may also be embedded in other financial instruments. Derivatives embedded in other financial instruments are valued as separate derivatives if they meet the bifurcation criteria of an embedded derivative. Such criteria include that the entire instrument is not marked to market through earnings, the economic characteristics and risks of the embedded contract terms are not clearly and closely related to those of the host contract and the embedded contract terms would meet the definition of a derivative on a stand-alone basis.
Foreign Currency Transactions and Translation	Foreign Currency Transactions Monetary assets and liabilities denominated in foreign currencies are translated into the applicable functional currency of the entity at exchange rates prevailing at the balance sheet date. Revenue and expenses are translated at the average rate for the period. The gains and losses from foreign currency denominated transactions are included in foreign exchange gain/loss in the consolidated statement of operations. Foreign Currency Translation The consolidated financial statements are presented in U.S. dollars. The functional currency of each subsidiary is the currency of the primary economic environment in which the subsidiary operates. For each subsidiary, assets and liabilities denominated in this functional currency are translated into U.S. dollars at the exchange rates in effect at the balance sheet dates and revenues and expenses are translated at the average exchange rates prevailing during the month of the respective transactions. The effect of foreign currency translation adjustments not affecting net income are included in Shareholders’ equity under the “Cumulative translation adjustment” account as a component of “Accumulated other comprehensive income”.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents consist of cash in banks and highly liquid investments with original terms to maturity at the date of acquisition of less than three months.
Short Term Investments	Short-Term Investments Short-term investments are designated as “held to maturity” and accounted for at amortized cost using the effective interest rate method. Short-term investments comprise guaranteed investment certificates with original maturities of one-year or less at the date of investment and their carrying value approximates their fair value.
Restricted Short-Term Investments	Restricted Short-Term Investments Restricted short-term investments are amounts held specifically as collateral for bank guarantees that the Company has entered into for security against potential procedural costs pursuant to a court order regarding patent infringement whereby the Company is the plaintiff. The bank guarantees total 1,850,000 Euros and are valid until March 28, 2019. They are automatically extended by periods of one year unless either party informs the other party at least sixty days before the current expiry date that they elect not to extend the bank guarantee. The restricted short-term investment acts as collateral should this renewal not take place and/or the requirement for the security and hence, the restricted short-term investments is no longer required by the court.
Accounts Receivable, Net	Accounts Receivable, Net The accounts receivable balance reflects invoices and is presented net of an allowance for doubtful accounts. The allowance for doubtful accounts represents the Company’s best estimate of probable losses that may result from the inability of its customers to make required payments. Reserves are established and maintained against estimated losses based upon historical loss experience, past due accounts and specific account analysis. The Company regularly reviews the level of allowances for doubtful accounts and adjusts the level of allowances as needed. Consideration is given to accounts past due as well as other risks in the current portion of the accounts.
Unbilled Revenue	Unbilled Revenue Unbilled Revenue includes unbilled amounts typically resulting from sales under long-term contracts when the cost-to-cost method of revenue recognition is utilized and revenue recognized exceeds the amount billed to the customer accounted for under Accounting Standards Update No. 2014-09 “Revenue from Contracts with Customers” (“ASC 606”).
Inventories	Inventories Inventories are measured at the lower of cost or net realizable value. The cost of inventories is determined on the weighted average basis. Cost includes the cost of acquired material plus, in the case of manufactured inventories, direct labor applied to the product and the applicable share of manufacturing overhead, including rent expense and depreciation based on normal operating capacity.
Property Plant and Equipment	Property Plant and Equipment Property plant and equipment is carried at cost less accumulated depreciation and impairment. Depreciation is calculated on the straight-line basis over the estimated useful lives of the assets as follows: Leasehold improvements term of the lease Computer equipment and software 3 years Furniture and fixtures 5 years Machinery and equipment 4-7 years Building 20 years
Intangible Assets	Intangible Assets Intangibles consist of patents, developed software, customer relationships and brand associated with various acquisitions. Patents include patents and patent rights (hereinafter, collectively “patents”) and are carried at cost less accumulated amortization and impairments. Developed software is initially recorded at fair value based on the present value of the estimated net future income-producing capabilities of software products acquired in acquisitions. Brand is initially recorded at fair value based on the present value of the estimated net future income-producing capabilities of the asset. Customer relationships represent acquired customer relationships with customers of acquired companies and are either based upon contractual or legal rights or are considered separable; that is, capable of being separated from the acquired entity and being sold, transferred, licensed, rented or exchanged. These customer relationships are initially recorded at their fair value based on the present value of expected future cash flows. Amortization is calculated on a straight-line basis over the estimated useful lives of the intangible assets as follows: Patents up to 20 years Developed Software 5 years Customer relationship and backlog 7 years Brand 7 years The Company continually evaluates the remaining estimated useful life of its intangible assets being amortized to determine whether events and circumstances warrant a revision to the remaining period of amortization.
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets The Company reviews long-lived assets (“LLA”) such as property and equipment and intangible asset groups for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset or asset group may not be recoverable. These events and circumstances may include significant decreases in the market price of an asset or asset group, significant changes in the extent or manner in which an asset or asset group is being used by the Company or in its physical condition, a significant change in legal factors or in the business climate, a history or forecast of future operating or cash flow losses, significant disposal activity, a significant decline in the Company’s share price, a significant decline in revenues or adverse changes in the economic environment. When indicators of impairment exist, LLA impairment is tested using a two-step process. The Company performs a cash flow recoverability test as the first step, which involves comparing the estimated undiscounted future cash flows for the asset group to the carrying amount of the asset group. If the net cash flows of the asset group exceed its carrying amount, the asset group is not considered to be impaired. If the carrying amount of the asset group exceeds the net cash flows, there is an indication of potential impairment and the second step of the LLA impairment test is performed to measure the impairment amount. The second step involves determining the fair value of the asset group. Fair value is determined using valuation techniques that are in accordance with U.S. GAAP, including the market approach, income approach and cost approach. If the carrying amount of the asset group exceeds its fair value, then the excess represents the maximum amount of potential impairment that will be allocated to the asset group, with the limitation that the carrying value of each asset cannot be reduced to a value lower than that of its fair value. The total impairment amount allocated is recognized as a non-cash impairment loss.
Investment in Joint Venture	Investment in Joint Venture The equity method is used to account for investments in joint ventures and certain other non-controlled entities when the Company has the ability to exercise significant influence over operating and financial policies of the investee, even though the investor holds 50% (joint control) or less of the voting common shares. Under this method, the investment, originally recorded at cost, is adjusted to recognize the Company’s share of net earnings or losses and other changes in equity of the affiliate as they occur, with losses limited to the extent of the Company’s investment in, advances to and commitments to the investee.
Goodwill	Goodwill Goodwill is recorded as at the date of the business combination and represents the excess of the purchase price of acquired businesses over the fair value assigned to identifiable assets acquired and liabilities assumed. Goodwill is tested for impairment at the reporting unit level by first performing a qualitative assessment to determine whether it is more likely than not that the fair value of the reporting unit is less than its carrying value. The qualitative assessment considers the following factors: macroeconomic conditions, industry and market considerations, cost factors, overall company financial performance, events affecting the reporting unit and changes in the Company’s fair value. If the reporting unit does not pass the qualitative assessment, the Company carries out a quantitative test for impairment of goodwill. This is done by comparing the fair value of the reporting unit with the carrying value of its net assets. If the fair value of the reporting unit is greater than its carrying value, no impairment results. If the fair value of the reporting unit is less than its carrying value, an impairment loss would be recognized in the Consolidated Statements of Operations in an amount equal to that difference, limited to the total amount of goodwill allocated to that reporting unit. The Company has three reporting units.
Deferred Revenue	Deferred Revenue Deferred revenue is comprised of cash collected from customers and billings to customers on contracts in advance of work performed, advance payments negotiated as a contract condition, including billings in excess of costs and estimated earning on uncompleted contracts. The Company records provisions for estimated losses on uncompleted contracts in the period in which such losses become known. The cumulative effects of revisions to contract revenues and estimated completion costs are recorded in the accounting period in which the amounts become evident and can be reasonably estimated. These revisions can include such items as the effects of change orders and claims, warranty claims, liquidated damages or other contractual penalties and adjustments for contract closeout settlements.
Revenue Recognition	Revenue Recognition The Company recognizes 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. The following paragraphs describe the specific revenue recognition policies for each of the Company’s significant types of revenue by segment. Licensing segment Under ASC 606, licenses are considered licenses to functional intellectual property. The standard specifically outlines that patents, underlying highly functional items, are considered functional intellectual property (“IP”). Licenses to functional IP are considered satisfied at a point in time (i.e. when the license becomes effective) and all the revenue is recognized at that point in time. Payment is either due immediately or within 30 days. The one exception to this guidance is related to revenue generated from sales or usage-based royalties promised in exchange for a license of IP. Customers generally report their royalty obligations one quarter in arrears and accordingly, the Company estimates the expected royalties to be reported for an accounting period, with a true up to the actual royalties reported in the following financial reporting period. Payment is due upon submission of the royalty report. Intelligent systems segment Contracted Projects The majority of sales of integrated systems are delivered as contracted projects that span a time period of less than 1 year to more than 5 years. Governments and private enterprises control all of the work in progress as intelligent transportation systems are being developed and installed. The Company’s contract types include fixed price and time and materials contracts. Contract revenue includes amounts expected to be received in exchange for the good or services plus any contract amendments that are expected to be received. Payment terms are based on completion of milestones throughout the project life for fixed price contracts and monthly for time and materials projects. Many of these projects have distinct performance obligations typically encompassing one or more of installation, maintenance and warranty. A contract’s transaction price is allocated to each distinct performance obligation using the best estimate of the standalone selling price of each distinct good or service in the contract. The primary method used to estimate standalone selling price is the expected cost plus margin approach. Revenue is recognized when or as the performance obligation is satisfied. Revenue for fixed price contracts is recognized over time using the cost-to-cost input method. Because control is transferred over time, revenue is recognized based on the extent of progress towards completion of the performance obligation. The company reviews and updates the contract related estimates regularly. Determining the contract costs and estimates to complete requires significant judgment. Adjustments are recognized in profit on contracts under the cumulative catch-up method in the period the adjustment is identified. If the Company anticipates the estimated remaining costs to completion will exceed the value allocated to the performance obligation, the resulting loss will be recognized immediately. For time and materials contracts, labor and material rates are established within the contract. Revenues from time and materials contracts are recognized progressively on the basis of costs incurred during the period plus the estimated margin earned. Maintenance Revenue Maintenance revenue from the Intelligent systems segment are considered recurring revenues. These service contracts are typically time and materials, but some are fixed price. Revenues are earned similar to contracted projects discussed above. Services are billed on a monthly basis and collected shortly thereafter. Product Sales Product sales revenue is recognized when control transfers to the customer which depends on the individual terms which can vary between when the product leaves the Company’s warehouse and when it is received at the customer’s warehouse. For some international shipments, when the buyer has no right of return, transfer occurs upon loading the goods onto the relevant carrier at the port of the seller. Customers are billed when transfer of control occurs and payments are typically due within 30 days. Enterprise Software Segment Software Licenses The Enterprise software segment provides bolt-on software products to enhance enterprise resource planning (“ERP”) -based asset maintenance systems. These software licenses contain up to five separate performance obligations: the license, implementation services, training services, post-contract customer support (“PCS”) and enhancement of software. Customers obtain access to licenses through online software and each additional component is added incrementally at the stand-alone market price which represents the price allocated to each performance obligation. Payment for licenses and services is received prior to delivery of product code for software or software keys for PCS. When selling the licensed software, the Company is providing the customer with the right to use its intellectual property and does not provide significant modifications or updates therefore revenue is recognized at the point in time when the customer gains control of the license, typically at contract inception. Implementation and training services, PCS and enhancement of software are recognized over time based on time lapsed as this best represents the value transferred to the customer based on the specifications for each within the contract.
Research and Development	Research and Development Research costs are charged to expense in the periods in which they are incurred. Software development costs are deferred and amortized when technological feasibility has been established, or otherwise are expensed as incurred.
Warranties	Warranties The Company records the estimated costs of product warranties at the time revenue is recognized. Warranty obligation arises from the Company having to replace goods and/or services that have failed to meet required customer specifications due to breakdown or error related to product or workmanship. The Company’s warranty obligations are affected by product failure rates, differences in warranty periods, regulatory developments with respect to warranty obligations in the countries in which the Company carries on business, freight expense and material usage and other related repair costs. The Company’s estimates of costs are based upon historical experience and expectations of future return rates and unit warranty repair costs. If the Company experiences increased or decreased warranty activity or increased or decreased costs associated with servicing those obligations, revisions to the estimated warranty liability would be recognized in the reporting period when such revisions are made.
Capitalized Contract Costs	Capitalized Contract Costs As part of obtaining contacts with certain customers, the Company incurs upfront costs such as sales commissions. The Company expenses these sales commissions when incurred because the amortization period generally would have been one year or less. Sales commissions are recorded in selling, general and administrative expenses in the Consolidated Statements of Operations.
Advertising Costs	Advertising Costs The Company expenses all advertising costs as incurred. These costs are included in selling, general and administrative costs.
Financing Costs	Financing Costs Financing costs are comprised of borrowing cost to the extent applicable, foreign currency gains and losses on the translation of foreign-denominated borrowings, unwinding of the discount on provisions, changes in the fair value of financial assets and financial liabilities at fair value through profit or loss and gains and losses on hedging instruments recognized through profit and loss, if any.
Leases	Leases Operating lease payments are recognized as selling, general and administrative expenses on a straight‑line basis over the lease term. If lease incentives are received to enter into operating leases, such incentives are recognized as a liability. The aggregate benefit of incentives is recognized as a reduction of rental expense on a straight‑line basis, except where another systematic basis is more representative of the time pattern in which economic benefits from the leased asset are consumed.
Computation of Earnings (Loss) Per Share	Computation of Earnings (Loss) Per Share Basic earnings/loss per share is computed using the weighted average number of common shares outstanding during the year. Diluted earnings/loss per share are computed using the treasury stock method.
Business Segment Information	Business Segment Information ASC Topic 280, “Segment Reporting” (“Topic 280”), establishes standards for reporting, by public business enterprises, information about operating segments, products and services, geographic areas and major customers. The method of determining what information to report under Topic 280, is based on the way that an entity organizes operating segments for making operational decisions and how the entity’s management and chief operating decision maker assess an entity’s financial performance.
Income Taxes, Deferred Taxes and Investment Tax Credits	Income Taxes, Deferred Taxes and Investment Tax Credits The Company uses the liability method of accounting for income taxes. Deferred income tax assets and liabilities are determined based on the difference between the accounting and tax bases of the assets and liabilities and measured using the enacted tax rates that are expected to be in effect when the differences are estimated to be reversed. In assessing the realizability of deferred income tax assets, management considers whether it is more likely than not that some portion or all of the deferred income tax assets will not be realized. The realization of deferred income tax assets is dependent upon the generation of sufficient future taxable income during the periods prior to the expiration of the associated tax attributes. The Company is also engaged in scientific research and experimental development giving rise to investment tax credits that may be available to reduce future taxes payable in certain jurisdictions. In calculating income taxes and investment tax credits, consideration is given to factors such as current and future tax rates in the different jurisdictions, non-deductible expenses, qualifying expenditures and changes in tax law. In addition, management makes judgments on the ability of the Company to realize deferred taxes and investment tax credits reported as assets based on their estimations of amounts and timing of future taxable income and future cash flows in the related jurisdiction.
Future Accounting Pronouncements and Adoption of Accounting Standards	Future Accounting Pronouncements Leases In February 2016, the FASB issued ASU 2016-2, “Leases” and issued subsequent amendments to the initial guidance during 2018, collectively referred to as “Topic 842.” The guidance requires companies to include lease obligations in their balance sheets, including a dual approach for lessee accounting under which a lessee would account for leases as finance leases or operating leases. Both finance leases and operating leases will result in the lessee recognizing a right-of-use (“ROU”) asset and a corresponding lease liability. For finance leases the lessee would recognize interest expense and amortization of the ROU asset and for operating leases, the lessee would recognize a straight-line total lease expense. Topic 842 can be applied either (i) retrospectively to each prior reporting period presented with the option to elect certain practical expedients or (ii) retrospectively with the cumulative effect recognized at the date of initial application and requiring certain additional disclosures. The guidance is effective for interim and annual periods beginning after December 15, 2018, with earlier adoption permitted. The Company expects to recognize operating lease liabilities of $4,306 with corresponding ROU assets of the same amount based on the present value of the remaining least payments of the respective lease terms. The new standard is not expected to have a material impact on the Company’s results of operations or cash flows. The Company intends to adopt the standard on a modified retrospective basis in the first quarter of 2019. Credit Losses on Financial Instruments In June 2016, FASB issued Accounting Standards Update (ASU) 2016-13 “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments” (“ASU 2016-13”), which requires measurement and recognition of expected credit losses for financial assets held. ASU 2016-13 is effective for the Company in the first quarter of its fiscal year ending December 31, 2021, with earlier adoption permitted beginning in the first quarter of its fiscal year ending December 31, 2020. The Company is currently assessing the impact of this new standard. Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income In February 2018 ASB issued ASU 2018-02 “Income Statement – Reporting Comprehensive Income (Topic 220)” (“ASU 2018-02”) that gives companies the option to reclassify stranded tax effects resulting from the newly enacted U.S. Tax Cuts and Jobs Act from accumulated other comprehensive income to retained earnings. A company will need to disclose if it elects not to adopt ASU 2018-02. The guidance will be effective for fiscal years beginning after December 15, 2018 and interim periods within the fiscal year. Early adoption will be permitted, including adoption in any interim period, for financial statements that have not yet been issued or made available for issuance. Entities will have the option to apply the amendments retrospectively or to record the reclassification as of the beginning of the period of adoption. The Company is currently assessing the impact of this new standard. Share-based payment awards In June 2018, the FASB issued ASU 2018-07 – “Compensation – Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting”. This guidance largely aligns the accounting for share-based payment awards issued to employees and non-employees. Under previous GAAP, the accounting for non-employee share-based payments differed from that applied to employee awards, particularly with regard to the measurement date and the impact of performance conditions. Under the new guidance, the existing employee guidance will apply to nonemployee share-based transactions (as long as the transaction is not effectively a form of financing), with the exception of specific guidance related to the attribution of compensation cost. The cost of nonemployee awards will continue to be recorded as if the grantor had paid cash for the goods or services. In addition, the contractual term will be able to be used in lieu of an expected term in the option-pricing model for nonemployee awards. This guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within that fiscal year. The Company is currently assessing the impact of this new standard. Fair Value Measurement In August 2018, the FASB issued Accounting Standards Update 2018-13 “Fair Value Measurement (Topic 820): Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement” that has been issued as part of the FASB’s disclosure framework project. The amendments in this update modify the disclosure requirements on fair value measurement based on concepts in the FASB Concept Statement, Conceptual Framework for Financial Reporting – Chapter 8: Notes to Financial Statements Intangibles – Goodwill and Other- Internal-Use Software In August 2018, the FASB issued Accounting Standards Update 2018-15 – Intangibles – Goodwill and Other – Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract that provides guidance on a customer’s accounting for implementation, set-up and other upfront costs incurred in a cloud computing arrangement that is hosted by the vendor, i.e. a service contract. Under this new guidance, customers will apply the same criteria for capitalizing implementation costs as they would for an arrangement that has a software license. This new guidance also prescribes the balance sheet, income statement and cash flow classification of the capitalized implementation costs and related amortization expense and requires additional quantitative and qualitative disclosures. This guidance is effective for fiscal years beginning after December 15, 2019 and interim periods within those fiscal years. The Company is currently assessing the impact of this new standard.
Adoption of ASU [Member]
Future Accounting Pronouncements and Adoption of Accounting Standards	ASU 2017-04 , Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment In January 2017, the FASB issued ASU No. 2017-04 “Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment” which simplifies the subsequent measurement of goodwill and eliminates Step 2 from the goodwill impairment test. The standard is effective for annual periods beginning after December 15, 2019 but the Company opted for early adoption for the goodwill impairment test that was completed as of December 31, 2018. ASU 2016-16 Intra-entity Transfers of Assets Other Than Inventory In October 2016, the FASB issued ASU 2016-16 “Income taxes on intra-entity transfers of assets other than inventory” to improve the accounting on income taxes on intra-entity transfers. The ASU requires that an entity recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs, rather than defer the income tax effect under previous guidance. The Company adopted this ASU on a modified retrospective basis in the first quarter of 2018. The cumulative effect of the adoption is an increase to shareholders’ equity of $2.9 million due to the adjustment to the accumulated deficit. ASU 2014-09 Revenue from Contracts with Customers In May 2014, the FASB issued Accounting Standards Update No. 2014-09 (ASU 2014-09) “Revenue from Contracts with Customers” (ASC 606). ASC 606 supersedes the revenue recognition requirements in ASC 605 “Revenue Recognition,” 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 which the entity expects to be entitled to in exchange for those goods or services. The Company adopted ASC 606 using the modified retrospective method applied to those contracts that were not yet complete as of January 1, 2018. Results for reporting periods beginning after January 1, 2018 are presented under Topic ASC 606, while prior period amounts are not adjusted and continue to be reported in accordance with our historic accounting under ASC 605. With respect to its Licensing segment, under the Topic 605, licensing companies report revenue to the Company from per-unit royalty-based arrangements one quarter in arrears, resulting in revenue being recognized on the same basis. Under the new guidance, the Company estimates the per-unit royalty-based revenue each period. The new standard also significantly impacts the timing of revenue recognition associated with its fixed fee “right to use” arrangements where under the new standard the Company recognizes license revenues at the time of signing a license agreement (upfront) rather than recognizing revenue over the term of the arrangement. With respect to its Intelligent systems segment, for the majority of its long-term contracts, the Company recognizes revenue and earnings over time as the work progresses because of the continuous transfer of control to the customer. The adoption of this standard has impacted revenue recognition in relation to the allocation of contract revenues between installations, maintenance agreements and warranty on some long-term fixed price contracts. The adoption of ASC 606 does not have a significant impact on the amount and timing of how revenue is recognized within the Enterprise software segment. The Company opted to use the following practical expedients: 1. For contracts that were modified before implementation, the Company has considered the aggregate effect of all modifications when identifying the satisfied and unsatisfied performance obligations, determining the transaction price and allocating the transaction price to satisfied and unsatisfied performance obligations; 2. The Company will not adjust the promised amount of consideration for the effects of a significant financing component if the entity expects, at contract inception, that the period between when the entity transfers a promised good or service to the customer and when the customer pays for that good or service will be one year or less. The cumulative effect of the changes made to the Company’s consolidated January 1, 2018 balance sheet for the adoption of ASU 2016-16 and ASU 2014-09 were as follows: Adjustments arising from implementation of ASU 2014-09 Balances as at December 31, 2017 ASU 2016-16 Licensing Intelligent Systems Balances as at January 1, 2018 Assets Unbilled revenue $ 3,045 $ - $ 6,376 $ (565 ) $ 8,856 Deferred income tax assets 20,195 2,949 - 150 23,294 Liabilities Deferred income tax liabilities 7,291 - 1,689 - 8,980 Equity Deficit (206,939 ) 2,949 4,687 (415 ) (199,718 ) The following tables disclose the impact of adoption, by segment, on the Company’s consolidated statement of operations for the twelve months ended December 31, 2018: For the year ended December 31, 2018 Adjustments arising from implementation of ASU 2014-09 As reported Licensing Intelligent Systems Balances without ASU 2014-09 Revenues License $ 23,544 $ 5,563 $ - $ 29,107 Systems 29,252 - (272 ) 28,980 Services 2,629 - - 2,629 Recurring 21,976 230 141 22,347 Costs and expenses Deferred income tax expense (recovery) (8,345 ) 1,535 (34 ) (6,844 ) Net loss (49,120 ) 4,258 (97 ) (44,959 ) The following table discloses the impact of adoption, by segment, on the Company’s consolidated balance sheet as at December 31, 2018: Adjustments arising from implementation of ASU 2014-09 As reported Licensing Intelligent Systems Balances without ASU 2014-09 Assets Unbilled revenue $ 3,990 $ (584 ) $ 433 $ 3,839 Deferred income tax assets 27,141 - (115 ) $ 27,026 Liabilities Deferred income tax liabilities 4,337 (155 ) - 4,182 Equity Deficit (253,443 ) (429 ) 318 (253,554 ) During the first quarter of 2018, the Company also adopted ASU 2016-01 Financial Instruments – Recognition and Measurement of Financial Assets and Financial Liabilities, ASU 2016-15 Statement of Cash Flows – Classification of Certain Cash Receipts and Cash Payments, ASU 2017-01 Business Combinations (Topic 805) – Clarifying the Definition of a Business and ASU 2017-04 – Intangibles – Goodwill and Other – Simplifying the Test for Goodwill Impairment. The adoption of these standards did not have a material impact on the consolidated financial statements or the related note disclosures.
