| Basis of Presentation | BASIS OF PRESENTATION Nature of Business Pixelworks designs, develops and markets visual display processing semiconductors, intellectual property cores, software and custom application specific integrated circuits ("ASIC") solutions for high-quality energy efficient video applications. In addition, we offer a suite of solutions for advanced media processing and the efficient delivery and streaming of video. We enable worldwide manufacturers to offer leading-edge consumer electronics and professional display products, as well as video delivery and streaming solutions for content service providers. Our core visual display processing technology intelligently processes digital images and video from a variety of sources and optimizes the content for a superior viewing experience. Pixelworks’ video coding technology reduces storage requirements, significantly reduces bandwidth constraint issues and converts content between multiple formats to enable seamless delivery of video, including over-the-air ("OTA") streaming, while also maintaining end-to-end content security. The rapid growth in video-capable consumer devices, especially mobile, has increased the demand for visual display processing and video delivery technology in recent years. Our technologies can be applied to a wide range of devices from large-screen projectors to low-power mobile tablets, smartphones, high-quality video infrastructure equipment and streaming devices. Our products are architected and optimized for power, cost, bandwidth, and overall system performance, according to the requirements of the specific application. Our primary target markets include digital projection systems, tablets, smartphones, and OTA streaming devices. As of September 30, 2019, we had an intellectual property portfolio of 353 patents related to the visual display of digital image data. We focus our research and development efforts on developing video algorithms that improve quality, and architectures that reduce system power, cost, bandwidth and increase overall system performance and device functionality. We seek to expand our technology portfolio through internal development and co-development with business partners, and we continually evaluate acquisition opportunities and other ways to leverage our technology into other high-value markets. Pixelworks was founded in 1997 and is incorporated under the laws of the state of Oregon. On August 2, 2017, we acquired ViXS Systems, Inc., a corporation organized in Canada ("ViXS"). Condensed Consolidated Financial Statements The financial information included herein for the three and nine month periods ended September 30, 2019 and 2018 is prepared in accordance with U.S. generally accepted accounting principles ("U.S. GAAP") and is unaudited. Such information reflects all adjustments, consisting of only normal recurring adjustments, except as discussed below, that are, in the opinion of management, necessary for a fair presentation of the Company's condensed consolidated financial statements for these interim periods. The financial information as of December 31, 2018 is derived from our audited consolidated financial statements and notes thereto for the fiscal year ended December 31, 2018, included in Item 8 of our Annual Report on Form 10-K, filed with the Securities and Exchange Commission on March 13, 2019 and as amended on August 9, 2019, and should be read in conjunction with such consolidated financial statements. The results of operations for the three and nine month periods ended September 30, 2019 are not necessarily indicative of the results expected for future periods or for the entire fiscal year ending December 31, 2019. Immaterial Error Correction During the second quarter of 2019, the Company determined that the statute of limitations had previously expired related to a portion of a liability that had been accrued in prior periods. Management evaluated the materiality of the error, both quantitatively and qualitatively, and concluded that it was not material to the financial statements of any period presented. The Company has revised beginning retained earnings and corrected the error in the accompanying prior period financial information in these condensed consolidated financial statements. The following table sets forth the effect this immaterial error correction had on the Company’s unaudited condensed consolidated statements of operations for the three and nine month periods ended September 30, 2018:

The following table sets forth the effect this immaterial error correction had on the Company's unaudited condensed consolidated statement of cash flows for the nine month period ended September 30, 2018:
Recent Accounting Pronouncements In November 2018, the FASB issued Accounting Standards Update No. 2018-18, Collaborative Arrangements: Clarifying the Interaction Between Topic 808 and Topic 606 ("ASU 2018-18"). ASU 2018-18 requires transactions in collaborative arrangements to be accounted for under ASC 606 if the counterparty is a customer for a good or service (or bundle of goods and services) that is a distinct unit of account. The amendment also precludes entities from presenting consideration from transactions with a collaborator that is not a customer together with revenue recognized from contracts with customers. ASU 2018-18 is effective for fiscal years beginning after December 15, 2019, and interim periods in those fiscal years. We are currently assessing the impact of this update on our financial position, results of operations and cash flows. In February 2016, the FASB issued Accounting Standards Update No. 2016-02, Leases (Topic 842) ("ASC 842"), which requires lessees to recognize leases on the balance sheet and disclose key information about leasing arrangements. Topic 842 was subsequently amended by ASU No. 2018-01, Land Easement Practical Expedient for Transition to Topic 842; ASU No. 2018-10, Codification Improvements to Topic 842; and ASU No. 2018-11, Targeted Improvements. The new standard establishes a right-of-use model ("ROU") that requires a lessee to recognize a ROU asset and lease liability on the balance sheet for all leases with a term longer than 12 months. Leases are classified as finance or operating, with classification affecting the pattern and classification of expense recognition in the income statement. We adopted the new standard on January 1, 2019 and used the effective date as our date of initial application under the modified retrospective approach. Under the effective date method, financial information and disclosures prior to January 1, 2019 are not required to be restated. We elected the “practical expedient package,” which permits us not to reassess under the new standard our prior conclusions about lease identification, lease classification and initial direct costs. We did not elect the use-of-hindsight or the practical expedient pertaining to land easements; the latter not being applicable to us. We elected the short-term lease recognition exemption for all leases that qualify. This means, for those leases that qualify, we will not recognize ROU assets or lease liabilities, and this includes not recognizing ROU assets or lease liabilities for existing short-term leases of those assets in transition. We also elected the practical expedient to not separate lease and non-lease components for all of our leases. The adoption of this standard had the effect of increasing the assets and liabilities on our condensed consolidated balance sheet by $6,224 and $6,847, respectively, but did not have a material impact on our condensed consolidated statements of operations or cash flows. The most significant impact relates to (1) the recognition of new ROU assets and lease liabilities on our balance sheet for our office operating leases; and (2) providing significant new disclosures about our leasing activities. Upon adoption, we recognized operating lease liabilities of $6,847 based on the present value of the remaining minimum rental payments under current leasing standards for existing operating leases. We also recognized ROU assets of $6,224 which represents the operating lease liability adjusted for accrued rent and cease-use liabilities. Use of Estimates The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires us to make estimates and judgments that affect amounts reported in the financial statements and accompanying notes. Our significant estimates and judgments include those related to revenue recognition, valuation of excess and obsolete inventory, lives and recoverability of equipment and other long-lived assets, valuation of goodwill, valuation of share-based payments, income taxes, litigation and other contingencies. The actual results experienced could differ materially from our estimates.

| Balance Sheet Components | BALANCE SHEET COMPONENTS Accounts Receivable, Net Accounts receivable are contract assets that arise from the performance of our performance obligation pursuant to our contracts with our customers and represent our unconditional right to payment for the satisfaction of our performance obligations. They are recorded at invoiced amount and do not bear interest when recorded or accrue interest when past due. Accounts receivable are stated net of an allowance for doubtful accounts, which is maintained for estimated losses that may result from the inability of our customers to make required payments. Accounts receivable consists of the following:
The following is the change in our allowance for doubtful accounts:
Inventories Inventories consist of finished goods and work-in-process, and are stated at the lower of standard cost (which approximates actual cost on a first-in, first-out basis) or market (net realizable value). Inventories consist of the following:
Property and Equipment, Net Property and equipment consists of the following:
Acquired Intangible Assets, Net In connection with the acquisition of ViXS ("the Acquisition"), we recorded certain identifiable intangible assets. Acquired intangible assets resulting from this transaction were assigned to Pixelworks, Inc., and consist of the following:
Developed technology and customer relationships are amortized over a useful life of 3 to 5 years. Backlog was fully amortized as of September 30, 2018 and tradename was fully amortized as of March 31, 2019. Amortization expense for intangible assets was $374 and $1,130 for the three and nine months ended September 30, 2019, respectively, $298 and $894 were included in cost of revenue for the three and nine months ended September 30, 2019, respectively, and $76 and $236 were included in selling, general and administrative for the three and nine months ended September 30, 2019, respectively, in the condensed consolidated statements of operations. As of September 30, 2019, future estimated amortization expense is as follows:
Acquired intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. Conditions that would trigger an impairment assessment include, but are not limited to, past, current, or expected cash flow or operating losses associated with the asset. There were no such triggering events requiring an impairment assessment of other intangible assets during the nine months ended September 30, 2019. Goodwill Goodwill resulted from the Acquisition, whereby we recorded goodwill of $18,407. Goodwill is not amortized; however, we review goodwill for impairment annually and whenever events or changes in circumstances indicate that the fair value of the reporting unit may be less than it's carrying value. Conditions that would trigger an impairment assessment include, but are not limited to, a significant adverse change in our business climate or a current period operating or cash flow loss combined with a history of operating or cash flow losses or a projection or forecast that demonstrates continued losses or adverse changes in legal factors, regulation or business environment. There were no such triggering events requiring a goodwill impairment assessment during the nine months ended September 30, 2019. We perform our annual impairment assessment for goodwill on November 30 of each year. Accrued Liabilities and Current Portion of Long-Term Liabilities Accrued liabilities and current portion of long-term liabilities consist of the following:
Deferred revenues are contract liabilities that arise when cash payments are received or due in advance of the satisfaction of our performance obligations. Any increase in deferred revenues is driven by cash payments received or due in advance of satisfying our performance obligation pursuant to the contract with the customer. Any decrease in deferred revenues is due to the recognition of revenue related to satisfying our performance obligation. The changes in deferred revenue and the liability for warranty returns are as follows:
Short-Term Line of Credit On December 21, 2010, we entered into a Loan and Security Agreement with Silicon Valley Bank (the "Bank"), which was amended on December 14, 2012, December 4, 2013, December 18, 2015, December 15, 2016, July 21, 2017, December 21, 2017 and December 18, 2018 (as amended, the "Revolving Loan Agreement"). The Revolving Loan Agreement provides a secured working capital-based revolving line of credit (the "Revolving Line") in an aggregate amount of up to the lesser of (i) $10,000, or (ii) $1,000 plus 80% of eligible domestic accounts receivable and certain foreign accounts receivable. The Revolving Line has a maturity date of December 27, 2019. In addition, the Revolving Loan Agreement provides for non-formula advances of up to $10,000 which may be made solely during the last five business days of any fiscal month or quarter and which must be repaid by us on or before the fifth business day after the applicable fiscal month or quarter end. Due to their repayment terms, non-formula advances do not provide us with usable liquidity. The Revolving Loan Agreement, as amended, contains customary affirmative and negative covenants as well as customary events of default. The occurrence of an event of default could result in the acceleration of our obligations under the Revolving Loan Agreement, as amended, and an increase to the applicable interest rate, and would permit the Bank to exercise remedies with respect to its security interest. As of September 30, 2019, we were in compliance with all of the terms of the Revolving Loan Agreement, as amended. As of September 30, 2019 and December 31, 2018, we had no outstanding borrowings under the Revolving Line.

Convertible Debt |
9 Months Ended |

Sep. 30, 2019 | |
| Debt Disclosure [Abstract] | |
| Convertible Debt | CONVERTIBLE DEBT As part of the Acquisition, we assumed secured convertible debt and as a result of the change in control of ViXS, the convertible debt holders had a right to put the debt to the Company. A majority of the holders agreed to waive their right to accelerate and to accept 0.04836 share of our common stock for each share of ViXS common stock the holder would have been entitled to receive upon the exercise of the conversion option. On January 12, 2018, the Company provided notice to the holders of the convertible debt of its election to redeem the convertible debt in full as of March 13, 2018. Subsequently, certain holders of the convertible debt elected to convert their convertible debt into shares of common stock of Pixelworks pursuant to the terms of the convertible debt. This resulted in the issuance of 435,353 shares of our common stock which was valued at an aggregate of $2,644. We paid an aggregate of CAD $2,875 (equivalent to $2,220 USD) to redeem the convertible debt of those holders who did not elect to convert their convertible debt. The extinguishment of the debt during the first quarter of 2018 resulted in a gain of $1,272 which is recorded in interest income (expense) and other, net within our condensed consolidated statement of operations. For the three months ended March 31, 2018, interest expense consisted of $66 related to the contractual rate of interest and $69 related to accretion of the discount. During the three months ended March 31, 2018, we recorded net foreign currency losses of approximately $15 in other expense. Because the convertible debt was redeemed or paid in full as of March 31, 2018, there were no further expenses related to the convertible debt after that date.

Unrealized holding gains and losses are recorded in accumulated other comprehensive income, a component of shareholders’ equity, in the condensed consolidated balance sheets. Fair Value Measurements Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Three levels of inputs may be used to measure fair value:
The following table presents information about our assets measured at fair value on a recurring basis in the condensed consolidated balance sheets as of September 30, 2019 and December 31, 2018:
We primarily use the market approach to determine the fair value of our financial assets. The fair value of our current assets and liabilities, including accounts receivable and accounts payable approximates the carrying value due to the short-term nature of these balances. We have currently chosen not to elect the fair value option for any items that are not already required to be measured at fair value in accordance with U.S. GAAP.

| Restructurings | RESTRUCTURINGS In June 2019, we executed a restructuring plan to make the operation of the Company more efficient (the "2019 Plan"). The 2019 Plan included an approximately 2% reduction in workforce, primarily in the areas of sales and operations. In April 2018, we executed a restructuring plan to make the operation of the Company more efficient (the "2018 Plan"). The 2018 Plan included an approximately 5% reduction in workforce, primarily in the areas of development, marketing and administration. The 2018 plan also included closing the Hong Kong office and reducing the size of the Toronto office. In September 2017, in connection with the Acquisition, we executed a restructuring plan to secure significant synergies between ViXS and Pixelworks (the "2017 Plan"). The 2017 Plan included an approximately 15% reduction in workforce, primarily in the area of development, however, it also impacted administration and sales. Total restructuring expense included in our statement of operations for the three and nine month periods ended September 30, 2019 and 2018 is comprised of the following:
During the three months ended September 30, 2019, we did not record any restructuring expense. During the nine months ended September 30, 2019, we recorded $398 in restructuring expense related to the 2019 Plan. During the three months ended September 30, 2018, we recorded $414 in restructuring expense related to the 2018 Plan. During the nine months ended September 30, 2018, we recorded $19 in restructuring expense related to the 2017 Plan and $1,016 related to the 2018 Plan. The following is a rollforward of the accrued liabilities related to restructuring for the nine month period ended September 30, 2019:
The adjustment to accrued costs related to restructuring was due to adjusting the right-of-use asset associated with cease-use liabilities upon the adoption of ASC 842 and did not result in an adjustment to restructuring expense.

| Research and Development | RESEARCH AND DEVELOPMENT During the first quarter of 2017, we entered into a best efforts co-development agreement (the "Co-Development Agreement") with a customer to defray a portion of the research and development expenses that would be incurred in connection with our development of an integrated circuit product to be sold exclusively to the customer. Under the Co-Development Agreement, we retain ownership of any modifications or improvements to our pre-existing intellectual property and may use such improvements in products sold to other customers. Under the Co-development Agreement, $4,000 was payable by the customer within 60 days of the date of the agreement and two additional payments of $2,000 were each payable upon completion of certain development milestones. As amounts became due and payable, they were offset against research and development expense on a pro rata basis. We recognized offsets to research and development expense of $4,000 related to the Co-development Agreement during each of 2018 and 2017. All milestones under the Co-development Agreement were completed as of December 31, 2018.

| Leases [Abstract] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Leases | LEASES On January 1, 2019, we adopted the new requirements of ASC 842, under the modified retrospective approach, using the effective date method. Under the effective date method, financial information and disclosures prior to January 1, 2019 are not required to be restated. We determine if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use (“ROU”) assets, other current liabilities, and operating lease liabilities in our condensed consolidated balance sheets. ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. Operating lease ROU assets also exclude lease incentives received. For purposes of calculating operating lease liabilities, lease terms may be deemed to include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. We have operating leases for office buildings and one vehicle. Our leases have remaining lease terms of 1 year to 6 years. Supplemental information related to lease expense and valuation of the ROU assets and lease liabilities was as follows:
Future minimum lease payments under non-cancellable leases as of September 30, 2019 were as follows:
As of September 30, 2019, the Company had no operating lease liabilities that had not commenced. As required, the following disclosure is provided for periods prior to adoption of ASC 842.

| Revenue from Contract with Customer [Abstract] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Revenue | REVENUE Revenue is recognized when control of the promised good or service is transferred to our customers, in an amount that reflects the consideration we expect to be entitled to in exchange for those goods or services. Our principal revenue generating activities consist of the following: Product Sales - We sell integrated circuit products, also known as “chips” or “ICs”, based upon a customer purchase order, which includes a fixed price per unit. We have elected to account for shipping and handling as activities to fulfill the promise to transfer the goods, and not evaluate whether these activities are promised services to the customer. We generally satisfy our single performance obligation upon shipment of the goods to the customer and recognize revenue at a point in time upon shipment of the underlying product. Our shipments are subject to limited return rights subject to our limited warranty for our products sold. In addition, we may provide other credits to certain customers pursuant to price protection and stock rotation rights, all of which are considered variable consideration when estimating the amount of revenue to recognize. We use the “most likely amount” method to determine the amount of consideration to which we are entitled. Our estimate of variable consideration is reassessed at the end of each reporting period based on changes in facts and circumstances. Historically, returns and credits have not been material. Engineering Services - We enter into contracts for professional engineering services that include software development and customization. We identify each performance obligation in our engineering services agreements (“ESAs”) at contract inception. The ESA generally includes project deliverables specified by the customer. The performance obligations in the ESA are generally combined into one deliverable, with the pricing for services stated at a fixed amount. Services provided under the ESA generally result in the transfer of control over time. We recognize revenue on ESAs based on the proportion of labor hours expended to the total hours expected to complete the contract performance obligation. ESAs could include substantive customer acceptance provisions. In ESAs that include substantive customer acceptance provisions, we recognize revenue upon customer acceptance. License Revenue - On occasion, we derive revenue from the license of our internally developed intellectual property ("IP"). IP licensing agreements that we enter into generally provide licensees the right to incorporate our IP components in their products with terms and conditions that vary by licensee. Fees under these agreements generally include license fees relating to our IP and support service fees, resulting in two performance obligations. We evaluate each performance obligation, which generally results in the transfer of control at a point in time for the license fee and over time for support services. Other - From time-to-time, we enter into arrangements for other revenue generating activities, such as providing technical support services to customers through technical support agreements. In each circumstance, we evaluate such arrangements for our performance obligations which generally results in the transfer of control for such services over time. Historically, such arrangements have not been material to our operating results. The following table provides information about disaggregated revenue based on the preceding categories for the three and nine months ended September 30, 2019 and 2018:
For segment information, including revenue by geographic region, see "Note 12: Segment Information". Our contract balances include accounts receivable, deferred revenue and our liability for warranty returns. For information concerning these contract balances, see "Note 2: Balance Sheet Components". Payment terms and conditions for goods and services provided vary by contract; however, payment is generally required within 30 to 60 days of invoicing. We have not identified any material costs incurred associated with obtaining a contract with a customer which would meet the criteria to be capitalized, therefore, these costs are expensed as incurred. The aggregate amount of the transaction price allocated to unsatisfied performance obligations with an original expected duration of greater than one year is $300, which we expect to recognize ratably over the next 30 months.

Income Taxes |

| Income Tax Disclosure [Abstract] | |
| Incomes Taxes | INCOME TAXES The provision for income taxes during the 2019 and 2018 periods is primarily comprised of current and deferred tax expense in profitable cost-plus foreign jurisdictions, accruals for tax contingencies in foreign jurisdictions and benefits for the reversal of previously recorded foreign tax contingencies due to the expiration of the applicable statutes of limitation. We recorded a benefit for the reversal of previously recorded foreign tax contingencies of $31 and $19 during the first nine months of 2019 and 2018, respectively. As we do not believe that it is more likely than not that we will realize a benefit from our U.S. net deferred tax assets, including our U.S. net operating losses, we continue to provide a full valuation allowance against essentially all of those assets, therefore, we do not incur significant U.S. income tax expense or benefit. We have not recorded a valuation allowance against our other foreign net deferred tax assets, with the exception of Canada, as we believe that it is more likely than not that we will realize a benefit from those assets. As of September 30, 2019 and December 31, 2018, the amount of our uncertain tax positions was a liability of $1,613 and $1,661, respectively, as well as a contra deferred tax asset of $1,099 and $925, respectively. A number of years may elapse before an uncertain tax position is resolved by settlement or statute of limitation. Settlement of any particular position could require the use of cash. If the uncertain tax positions we have accrued for are sustained by the taxing authorities in our favor or if the statute of limitation expires, the reduction of the liability will reduce our effective tax rate. We reasonably expect reductions in the liability for unrecognized tax benefits and interest and penalties of approximately $113 within the next twelve months due to the expiration of statutes of limitation in foreign jurisdictions. We recognize interest and penalties related to uncertain tax positions in income tax expense in our condensed consolidated statements of operations.

| Risks and Uncertainties [Abstract] | |
| Risks and Uncertainties | RISKS AND UNCERTAINTIES Concentration of Suppliers We do not own or operate a semiconductor fabrication facility and do not have the resources to manufacture our products internally. We rely on a limited number of foundries and assembly and test vendors to produce all of our wafers and for completion of finished products. We do not have any long-term agreements with any of these suppliers. In light of these dependencies, it is reasonably possible that failure to perform by one of these suppliers could have a severe impact on our results of operations. Additionally, the concentration of these vendors within Taiwan and the People’s Republic of China increases our risk of supply disruption due to natural disasters, economic instability, political unrest or other regional disturbances. Risk of Technological Change The markets in which we compete, or seek to compete, are subject to rapid technological change, frequent new product introductions, changing customer requirements for new products and features, and evolving industry standards. The introduction of new technologies and the emergence of new industry standards could render our products less desirable or obsolete, which could harm our business. Concentrations of Credit Risk Financial instruments that potentially subject us to concentrations of credit risk consist of cash equivalents and accounts receivable. We limit our exposure to credit risk associated with cash equivalent balances by holding our funds in high quality, highly liquid money market accounts. We limit our exposure to credit risk associated with accounts receivable by carefully evaluating creditworthiness before offering terms to customers.

| Commitments and Contingencies | COMMITMENTS AND CONTINGENCIES Indemnifications Certain of our agreements include indemnification provisions for claims from third-parties relating to our intellectual property. It is not possible for us to predict the maximum potential amount of future payments or indemnification costs under these or similar agreements due to the conditional nature of our obligations and the unique facts and circumstances involved in each particular agreement. We have not made any payments under these agreements in the past, and as of September 30, 2019, we have not incurred any material liabilities arising from these indemnification obligations. In the future, however, such obligations could materially impact our results of operations. Legal Proceedings We are subject to legal matters that arise from time to time in the ordinary course of our business. Although we currently believe that resolving such matters, individually or in the aggregate, will not have a material adverse effect on our financial position, our results of operations, or our cash flows, these matters are subject to inherent uncertainties and our view of these matters may change in the future. Other Contractual Obligation As part of the Acquisition, we acquired debt associated with an agreement with the Government of Canada called Technology Partnerships Canada ("TPC"). As part of the TPC agreement, ViXS Systems Inc. was provided funding to assist in research and development expenses of which a portion was later required to be repaid because the conditions for repayment were met. The scheduled payments are made on a quarterly basis and end in January 2024. As of September 30, 2019, $474 is included in accrued liabilities and current portion of long-term liabilities in our consolidated balance sheet and $474 is included in long-term liabilities, net of current portion in our consolidated balance sheet.

The financial information as of December 31, 2018 is derived from our audited consolidated financial statements and notes thereto for the fiscal year ended December 31, 2018, included in Item 8 of our Annual Report on Form 10-K, filed with the Securities and Exchange Commission on March 13, 2019 and as amended on August 9, 2019, and should be read in conjunction with such consolidated financial statements. The results of operations for the three and nine month periods ended September 30, 2019 are not necessarily indicative of the results expected for future periods or for the entire fiscal year ending December 31, 2019. |
| Recent Accounting Pronouncements | Recent Accounting Pronouncements In November 2018, the FASB issued Accounting Standards Update No. 2018-18, Collaborative Arrangements: Clarifying the Interaction Between Topic 808 and Topic 606 ("ASU 2018-18"). ASU 2018-18 requires transactions in collaborative arrangements to be accounted for under ASC 606 if the counterparty is a customer for a good or service (or bundle of goods and services) that is a distinct unit of account. The amendment also precludes entities from presenting consideration from transactions with a collaborator that is not a customer together with revenue recognized from contracts with customers. ASU 2018-18 is effective for fiscal years beginning after December 15, 2019, and interim periods in those fiscal years. We are currently assessing the impact of this update on our financial position, results of operations and cash flows. In February 2016, the FASB issued Accounting Standards Update No. 2016-02, Leases (Topic 842) ("ASC 842"), which requires lessees to recognize leases on the balance sheet and disclose key information about leasing arrangements. Topic 842 was subsequently amended by ASU No. 2018-01, Land Easement Practical Expedient for Transition to Topic 842; ASU No. 2018-10, Codification Improvements to Topic 842; and ASU No. 2018-11, Targeted Improvements. The new standard establishes a right-of-use model ("ROU") that requires a lessee to recognize a ROU asset and lease liability on the balance sheet for all leases with a term longer than 12 months. Leases are classified as finance or operating, with classification affecting the pattern and classification of expense recognition in the income statement. We adopted the new standard on January 1, 2019 and used the effective date as our date of initial application under the modified retrospective approach. Under the effective date method, financial information and disclosures prior to January 1, 2019 are not required to be restated. We elected the “practical expedient package,” which permits us not to reassess under the new standard our prior conclusions about lease identification, lease classification and initial direct costs. We did not elect the use-of-hindsight or the practical expedient pertaining to land easements; the latter not being applicable to us. We elected the short-term lease recognition exemption for all leases that qualify. This means, for those leases that qualify, we will not recognize ROU assets or lease liabilities, and this includes not recognizing ROU assets or lease liabilities for existing short-term leases of those assets in transition. We also elected the practical expedient to not separate lease and non-lease components for all of our leases. The adoption of this standard had the effect of increasing the assets and liabilities on our condensed consolidated balance sheet by $6,224 and $6,847, respectively, but did not have a material impact on our condensed consolidated statements of operations or cash flows. The most significant impact relates to (1) the recognition of new ROU assets and lease liabilities on our balance sheet for our office operating leases; and (2) providing significant new disclosures about our leasing activities. Upon adoption, we recognized operating lease liabilities of $6,847 based on the present value of the remaining minimum rental payments under current leasing standards for existing operating leases. We also recognized ROU assets of $6,224 which represents the operating lease liability adjusted for accrued rent and cease-use liabilities.
|
| Use of Estimates | Use of Estimates The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires us to make estimates and judgments that affect amounts reported in the financial statements and accompanying notes. Our significant estimates and judgments include those related to revenue recognition, valuation of excess and obsolete inventory, lives and recoverability of equipment and other long-lived assets, valuation of goodwill, valuation of share-based payments, income taxes, litigation and other contingencies. The actual results experienced could differ materially from our estimates.
|
| Receivables, Policy | Accounts receivable are contract assets that arise from the performance of our performance obligation pursuant to our contracts with our customers and represent our unconditional right to payment for the satisfaction of our performance obligations. They are recorded at invoiced amount and do not bear interest when recorded or accrue interest when past due. Accounts receivable are stated net of an allowance for doubtful accounts, which is maintained for estimated losses that may result from the inability of our customers to make required payments.
|
| Inventory, Policy | Inventories consist of finished goods and work-in-process, and are stated at the lower of standard cost (which approximates actual cost on a first-in, first-out basis) or market (net realizable value).
|
| Co-Development Arrangements, Policy | As amounts became due and payable, they were offset against research and development expense on a pro rata basis. |
