SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	Dec. 31, 2023
Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The accompanying consolidated financial statements include those of Harmonic and its wholly-owned subsidiaries, after elimination of all intercompany accounts and transactions. The Company has reclassified certain amounts previously reported in its consolidated financial statements that were not material, to conform to the current presentation. The Company’s fiscal quarters are based on 13-week periods, except for the fourth quarter which ends on December 31. Use of Estimates The preparation of consolidated financial statements in conformity with U.S. generally accepted accounting principles (“US GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. The Company’s reported financial positions or results of operations may be materially different under changed conditions or when using different estimates and assumptions, particularly with respect to significant accounting policies. If estimates or assumptions differ from actual results, subsequent periods are adjusted to reflect more current information. Cash and Cash Equivalents All highly liquid investments with an original maturity of three months or less at the date of purchase are considered cash equivalents. The carrying amount of cash and cash equivalents approximates fair value because of the short maturity of those instruments. Credit Risk and Major Customers/Supplier Concentration Financial instruments which subject the Company to concentrations of credit risk consist primarily of cash, cash equivalents, and accounts receivable. Cash and cash equivalents are invested in short-term, highly liquid, investment-grade instruments, in accordance with the Company’s investment policy. The investment policy limits the amount of credit exposure to any one financial institution, commercial or governmental issuer. The Company’s accounts receivable are derived from sales to worldwide cable, satellite, telco, and broadcast and media companies. The Company generally does not require collateral from its customers, and performs ongoing credit evaluations of its customers and provides for expected losses. The Company maintains an allowance for doubtful accounts based upon the expected collectability of its accounts receivable. Two customers had a balance greater than 10% of the Company’s net accounts receivable balance as of December 31, 2023. One customer had a balance greater than 10% of the Company’s net accounts receivable balance as of December 31, 2022. During the year ended December 31, 2023, 2022 and 2021, Comcast is the only customer that accounted for more than 10% of the Company’s total net revenue. Certain of the components and subassemblies included in the Company’s products are obtained from a single source or a limited group of suppliers. Although the Company seeks to reduce dependence on those sole source and limited source suppliers, the partial or complete loss of certain of these sources could have at least a temporary adverse effect on the Company’s results of operations and damage customer relationships. Revenue Recognition The Company classifies its total revenue in two categories on the face of the statement of operations, “Appliance and integration” and “SaaS and service. Appliance and integration revenue includes revenue from the sale of hardware products and perpetual software licenses, as well as the associated professional services such as testing, design, installation, commissioning, and integration, collectively referred to as “professional services. These professional service agreements, associated with the sale of hardware products and perpetual software licenses, are typically of a short duration and are considered an important component of the appliance business by management. SaaS and service revenue include usage fees for the Company’s SaaS platform and support service revenue from its appliance-based customers. The Company applies the provisions of ASC 606, Revenue from Contracts with Customers (ASC 606) as a single standard for revenue recognition that applies to all of its hardware products, software licenses and services arrangements and generally require revenues to be recognized upon the transfer of control of promised goods or services provided to its customers, reflecting the amount of consideration the Company expects to receive for those goods or services. Pursuant to ASC 606, revenue is recognized upon the application of the following steps: • identification of the contract, or contracts, with a customer; • identification of the performance obligations in the contract; • determination of the transaction price; • allocation of the transaction price to each performance obligation in the contract; and • recognition of revenues when, or as, the contractual performance obligations are satisfied. Hardware and Software: Revenue from the sale of hardware and software products is recognized when control is transferred. For most of the Company’s product sales (including sales to distributors and system integrators), control is transferred at the time the product is shipped or delivery has occurred because the customer has significant risks and rewards of ownership of the asset and the Company has a present right to payment at that time. The Company’s agreements with the distributors and system integrators have terms which are generally consistent with the standard terms and conditions for the sale of the Company’s equipment to end users, and do not provide for product rotation or pricing allowances, as are typically found in agreements with stocking distributors. Shipping and handling costs are accounted for as a fulfillment cost and are recorded in “Cost of revenue” in the Company’s Consolidated Statements of Operations. Sales tax and other amounts collected on behalf of third parties are excluded from the transaction price. Professional services: Revenues from professional services are generally recognized as the services are performed. SaaS services: Revenue for SaaS service is recognized ratably over the contractual term as the customer simultaneously receives and consumes the benefit of the underlying service. Over-usage fees are recognized as revenue when consumed and are included in the transaction price of an arrangement as variable consideration. Support and maintenance. Support and maintenance services are satisfied ratably over time as the customer simultaneously receives and consumes the benefits of the services. Arrangements with Multiple Performance Obligations. The Company has revenue arrangements that include multiple performance obligations. The Company allocates the transaction price to all distinct performance obligations based on their relative standalone selling prices (“SSP”). The Company may exercise judgment when determining whether products and services are considered distinct performance obligations that should be accounted for separately versus together. The determination of SSP is generally based on the contractually stated, observable prices of the promised goods and services charged when sold separately to the customer. Where SSP is not directly observable, we determine the SSP using information which considers multiple factors including, but not limited to, major product groupings, gross margin objectives and pricing practices. Pricing practices taken into consideration include discounts offered and applicable price lists. Contract Balances . Deferred revenue represents the Company’s obligation to transfer goods or services to a customer for which the Company has received consideration (or an amount of consideration is due) from the customer. The Company’s payment terms vary by the type and location of its customer and the products or services offered. The term between invoicing and when payment is due is not significant. For certain products or services and customer types, the Company requires payment before the products or services are delivered to the customer. The amount of revenues recognized during the years ended December 31, 2023 and 2022 that were included in the opening deferred revenue balance as of January 1, 2023 and 2022, respectively, were $54.1 million and $47.9 million. Contract assets exist when the Company has satisfied a performance obligation but does not have an unconditional right to consideration (e.g., because the entity first must satisfy another performance obligation in the contract before it is entitled to invoice the customer). Contract assets and deferred revenue consisted of the following: As of December 31, (in thousands) 2023 2022 Contract assets $ 4,772 $ 5,580 Deferred revenue $ 59,705 $ 80,471 Contract assets and the non-current portion of deferred revenue are reported as components of “Prepaid expenses and other current assets” and “Other non-current liabilities”, respectively, on the Consolidated Balance Sheets. Remaining performance obligations represent contracted revenues that had not yet been recognized and future revenue recognition is expected. The aggregate balance of the Company’s remaining performance obligations as of December 31, 2023, was $653.2 million, of which approximately 51% is expected to be recognized as revenue over the next 12 months and the remainder thereafter. Contract costs. The incremental costs of obtaining a contract are capitalized if the costs are expected to be recovered. Costs that are recognized as assets are amortized on a straight-line basis over the period during which the related goods or services transfer to the customer. Costs incurred to fulfill a contract are capitalized if they are not covered by other relevant guidance, relate directly to a contract, will be used to satisfy future performance obligations, and are expected to be recovered. The balances of net capitalized contract costs included in the Company’s Consolidated Balance Sheets were as follows: (in thousands) As of December 31, Balance Sheet Location 2023 2022 Prepaid expenses and other current assets $ 1,879 $ 1,766 Other non-current assets 1,944 1,337 Total net capitalized contract costs $ 3,823 $ 3,103 The amortization of the capitalized contract costs for the years ended December 31, 2023, 2022 and 2021 was $2.3 million , $2.2 million and $2.3 million, respectively. Refer to Note 16, “Segment Information, Geographic Information and Customer Concentration” for disaggregated revenue information. Inventories Inventories are stated at the lower of cost (determined on first-in, first-out basis) or net realizable value. The cost of inventories is comprised of material and manufacturing labor and overheads. The Company establishes provisions for excess and obsolete inventories to reduce such inventories to their estimated net realizable value after evaluation of historical sales, future demand and market conditions, expected product life cycles and current inventory levels. Such provisions are charged to cost of revenue in the Company’s Consolidated Statements of Operations. Property and Equipment Property and equipment are recorded at cost. Depreciation is computed using the straight-line method over the estimated useful lives of the assets. Estimated useful lives are generally five years for furniture and fixtures, three years for software and four years for machinery and equipment. Depreciation for leasehold improvements are computed using the shorter of estimated useful lives or the terms of the related leases. The Company reviews property and equipment for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. For the years ended December 31, 2023, 2022 and 2021, there were no impairment charges for property and equipment. Goodwill Goodwill is assigned to one or more reporting segments on the date of acquisition. We review our goodwill for impairment annually during our fourth quarter of each fiscal year and between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of any one of our reporting units below its respective carrying amount. The Company monitors changing business conditions as well as industry and economic factors, among others, for events which could trigger the need for an interim impairment analysis. In performing our goodwill impairment test, we first perform a qualitative assessment, which requires that we consider events or circumstances including macroeconomic conditions, industry and market considerations, cost factors, overall financial performance, changes in management or key personnel, changes in strategy, changes in customers, changes in the composition or carrying amount of a reporting segment’s net assets and changes in our stock price. If, after assessing the totality of events or circumstances, we determine that it is more likely than not that the fair values of our reporting segments are greater than the carrying amounts, then the quantitative goodwill impairment test is not performed. If the qualitative assessment indicates that the quantitative analysis should be performed, we then evaluate goodwill for impairment by comparing the fair value of each of our reporting segments to its carrying value, including the associated goodwill. To determine the fair values, we use the market approach based on comparable publicly traded companies in similar lines of businesses and the income approach based on estimated discounted future cash flows. Our cash flow assumptions consider historical and forecasted revenue, operating costs and other relevant factors. We completed our annual goodwill impairment test in the fourth quarter of fiscal 2023. We determined, after performing a qualitative review of each reporting segment, that it is more likely than not that the fair value of each of our reporting segments exceeds the respective carrying amounts. Accordingly, there was no indication of impairment and the quantitative goodwill impairment test was not performed. For the years ended December 31, 2023, 2022 and 2021, there were no impairment charges for goodwill. Leases The Company determines if an arrangement is a lease at inception. Operating lease liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. The Company’s lease contracts do not provide an implicit borrowing rate; hence the Company determined the incremental borrowing rate based on information available at lease commencement to determine the present value of lease liability. Right-of-use (“ROU”) assets related to our operating lease liabilities are measured at lease inception based on the initial measurement of the lease liability, plus any prepaid lease payments and less any lease incentives. As of December 31, 2023, the Company has operating leases primarily consisting of facilities with remaining lease terms of 1 year to 9 years, some of which included the option to extend the term. Optional periods to extend the lease, including by not exercising a termination option, are included in the lease term when it is reasonably certain that the option will be exercised. The Company amortizes ROU assets as operating lease expense on a straight-line basis over the lease term. Operating leases are included in “Operating lease right-of-use assets”, “Operating lease liabilities, current”, and “operating lease liabilities, non-current” in the Consolidated Balance Sheets. Foreign Currency The functional currency of the Company’s Israeli and Swiss subsidiaries is the U.S. dollar. All other foreign subsidiaries use the respective local currency as the functional currency. When the local currency is the functional currency, gains and losses from translation of these foreign currency financial statements into U.S. dollars are recorded as a separate component of other comprehensive income (loss) in stockholders’ equity. The Company’s foreign currency exposure is also related to its net position of monetary assets and monetary liabilities held by its foreign subsidiaries in their nonfunctional currencies. These monetary assets and liabilities are being remeasured into the subsidiaries’ respective functional currencies using exchange rates as of the balance sheet date. Such remeasurement gains and losses are included in “Other income (expense), net” in the Company’s Consolidated Statements of Operations. During the years ended December 31, 2023, and 2022, the Company recorded remeasurement loss of approximately $0.2 million and $0.3 million, respectively. During the year ended December 31, 2021, the Company recorded a remeasurement gain of $0.6 million. Derivative Instruments The Company enters into derivative instruments, primarily foreign currency forward contracts, to minimize the short-term impact of foreign currency exchange rate fluctuations on certain foreign currency denominated assets and liabilities as well as certain foreign currencies denominated expenses. The Company does not enter into derivative instruments for trading purposes and these derivatives generally have maturities within three months. The derivative instruments are recorded at fair value in prepaid expenses and other current assets or accrued and other current liabilities in the Company’s Consolidated Balance Sheets. The Company enters into derivative instruments to hedge existing foreign currency denominated assets or liabilities, the gains or losses on these hedges are recorded immediately in earnings to offset the changes in the fair value of the assets or liabilities being hedged. Research and Development Research and development (“R&D”) costs are expensed as incurred and consist primarily of employee salaries and related expenses, contractors and outside consultants, supplies and materials, equipment depreciation and facilities costs, all associated with the design and development of new products and enhancements of existing products. The Company’s French subsidiary participates in the French Crédit d’Impôt Recherche (“CIR”) program which allows companies to monetize eligible research expenses. The R&D credits receivable from the French government for spending on innovative R&D under the CIR program are recorded as an offset to R&D expenses. In the years ended December 31, 2023, 2022 and 2021, the Company had R&D credits of $6.2 million, $5.4 million and $5.7 million, respectively. Restructuring and Related Charges The Company’s restructuring charges consist primarily of employee severance, one-time termination benefits related to the reduction of its workforce, and other costs. Liabilities for costs associated with a restructuring activity are recognized when the liability is incurred and are measured at fair value. One-time termination benefits are expensed at the date the entity notifies the employee, unless the employee must provide future service, in which case the benefits are expensed ratably over the future service period. Termination benefits are calculated based on regional benefit practices and local statutory requirements. Warranty The Company accrues for estimated warranty costs at the time of revenue recognition and records such accrued liabilities as part of cost of revenue. Management periodically reviews its warranty liability and adjusts the accrued liability based on the terms of warranties provided to customers, historical and anticipated warranty claims experience, and estimates of the timing and cost of warranty claims. Advertising Expenses All advertising costs are expensed as incurred and included in “Selling, general and administrative expenses” in the Company’s Consolidated Statements of Operations. Advertising expense was $0.5 million, $0.7 million and $1.0 million for the years ended December 31, 2023, 2022 and 2021, respectively. Stock-based Compensation The Company measures and recognizes compensation expense for all stock-based compensation awards made to employees, including stock options, restricted stock units (“RSUs”) and stock purchase rights under the Company’s Employee Stock Purchase Plan (“ESPP”), based upon the grant-date fair value of those awards. The Company recognizes the impact of forfeitures as they occur. The fair value of the Company’s stock options and stock purchase rights under ESPP is estimated at grant date using the Black-Scholes option pricing model. The fair value of the Company’s RSUs and performance-based RSUs (“PRSUs”) is calculated based on the market value of the Company’s stock at the grant date. The fair value of the Company’s market-based RSUs (“MRSUs”) is estimated using the Monte-Carlo valuation model with market vesting conditions. The Company recognizes the stock-based compensation for options, RSUs, MRSUs and stock purchase rights under ESPP on straight-line basis over the requisite service period, which is generally the vesting period. The Company recognizes the stock-based compensation for PRSUs based on the probability of achieving performance criteria defined in the PRSU agreements. The Company estimates the number of PRSUs ultimately expected to vest and recognizes expense using the graded vesting attribution method over the requisite service period. Changes in the estimates related to probability of achieving certain performance criteria and number of PRSUs expected to vest could significantly affect the related stock-based compensation expense from one period to the next. Pension Plan Under French law, the Company’s subsidiary in France is obligated to provide for a defined benefit plan to its employees upon their retirement from the Company. The Company’s defined benefit pension plan in France is unfunded. The Company records its obligations relating to the pension plans based on calculations which include various actuarial assumptions including employees’ age and period of service with the company; projected mortality rates, mobility rates and increases in salaries; and a discount rate. The Company reviews its actuarial assumptions on an annual basis as of December 31 (or more frequently if a significant event requiring remeasurement occurs) and modifies the assumptions based on current rates and trends when it is appropriate to do so. The effect of modifications to those assumptions is recorded in other comprehensive income (loss) and amortized to net periodic benefit cost over the expected remaining period of service of the covered employees using the corridor method. The Company believes that the assumptions utilized in recording its obligations under its pension plan are reasonable based on its experience, market conditions and input from its actuaries. Income Taxes The Company accounts for income taxes using the asset and liability method of accounting for income taxes. The Company calculates and provides for income taxes in each of the tax jurisdictions in which it operates. The deferred tax assets and liabilities are recognized for future tax consequences attributable to temporary differences between the financial statement carrying values of existing assets and liabilities and their respective tax bases and all operating losses carried forward, if any. Deferred tax assets and liabilities are measured using tax rates expected to apply to taxable income in the years in which the applicable temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates or tax status is recognized in the statements of income in the period in which the change is identified. Deferred tax assets are reduced by a valuation allowance if, based on available evidence, it is more likely than not that some portion or all of the deferred tax assets will not be realized. The Company is subject to examination of its income tax returns by various tax authorities on a periodic basis. The Company regularly assesses the likelihood of adverse outcomes resulting from such examinations to determine the adequacy of its provision for income taxes. The Company has applied the provisions of the applicable accounting guidance on accounting for uncertainty in income taxes, which requires application of a more-likely-than-not threshold to the recognition and de-recognition of uncertain tax positions. If the recognition threshold is met, the applicable accounting guidance permits the Company to recognize a tax benefit measured at the largest amount of tax benefit that, in the Company’s judgment, is more than 50% likely to be realized upon settlement. It further requires that a change in judgment related to the expected ultimate resolution of uncertain tax positions be recognized in earnings in the period of such change. The Company files annual income tax returns in multiple taxing jurisdictions around the world. A number of years may elapse before an uncertain tax position is audited and finally resolved. While it is often difficult to predict the final outcome or the timing of resolution of any particular uncertain tax position, the Company believes that its reserves for income taxes reflect the most likely outcome. The Company adjusts these reserves and penalties, as well as the related interest, in light of changing facts and circumstances. Changes in the Company’s assessment of its uncertain tax positions or settlement of any particular position could materially and adversely impact the Company’s income tax rate, operating results, financial position and cash flows. Recently Adopted Accounting Pronouncements In August 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) No. 2020-06, Accounting for Convertible Instruments in an Entity’s Own Equity, which simplifies the accounting for convertible instruments and contracts on an entity’s own equity. The Company adopted ASU 2020-06 effective on January 1, 2022, using the modified retrospective method. Among other changes, ASU 2020-06 removes from U.S. GAAP the liability and equity separation model for convertible instruments with a cash conversion feature. As a result, the Company no longer separately presents in equity an embedded conversion feature for such debt. Similarly, the embedded conversion feature is no longer amortized into consolidated statement of operations as interest expense over the life of the instrument. The cumulative effect of the ASU adoption was as follows: Adjustments from Balance at Adoption of Balance at (in thousands) December 31, 2021 ASU 2020-06 January 1, 2022 Liabilities Convertible debt, current $ 36,824 $ 626 $ 37,450 Convertible debt, non-current 98,941 14,167 113,108 Mezzanine equity Convertible debt 883 (883) — Equity Additional paid-capital 2,387,039 (32,249) 2,354,790 Accumulated deficit (2,087,975) 18,339 (2,069,618) The Company was contractually required to settle the principal amount of the 2022 Notes and is contractually required to settle the principal amount of the 2024 Notes, in cash, and the 2022 Notes were settled in December 2022 upon maturity. Accordingly, the dilutive effect of the Company's 2022 Notes was, and the diluted effect of the 2024 Notes will be, limited to the conversion premium. From time to time, new accounting pronouncements are issued by the FASB, or other standards setting bodies, that are adopted by the Company as of the specified effective date. Unless otherwise discussed, the Company believes the impact of recently issued standards that are not yet effective will not have a material impact on its consolidated financial position, results of operations and cash flows upon adoption. Recently Issued Accounting Pronouncement In November 2023, the FASB issued ASU No. 2023-07, Segment Reporting, which expands annual and interim disclosure requirements for reportable segments, primarily through enhanced disclosures about significant segment expenses. The updated standard is effective for our annual periods beginning in fiscal 2024 and interim periods beginning in the first quarter of fiscal 2025. Early adoption is permitted. The Company is currently evaluating the impact the new accounting standard will have on its segment reporting disclosures in the notes to the consolidated financial statements. In December 2023, the FASB issued ASU No. 2023-09, Improvements to Income Tax Disclosures. This ASU requires disaggregated information about a reporting entity’s effective tax rate reconciliation as well as additional information on income taxes paid. The ASU is effective on a prospective basis for annual periods beginning after December 15, 2024. Early adoption is also permitted for annual financial statements that have not yet been issued or made available for issuance. This ASU will result in the required additional disclosures being included in our consolidated financial statements, once adopted.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVES AND HEDGING ACTIVITIES	DERIVATIVES AND HEDGING ACTIVITIES Derivatives Not Designated as Hedging Instruments (Balance Sheet Hedges) The Company transacts business in various foreign currencies and has established a program that primarily utilizes foreign currency forward contracts to offset the risks associated with the effects of certain foreign currency exposures. Under this program, the Company’s strategy is to enter into foreign currency forward contracts so that increases or decreases in its foreign currency exposures are offset by gains or losses on the foreign currency forward contracts in order to mitigate the risks and volatility associated with its foreign currency transactions. The Company may suspend this program from time to time. The Company’s foreign currency exposures typically arise from foreign currency exchange rate fluctuation on cash and certain trade and intercompany receivables and payables. The Company’s foreign currency forward contracts are generally short-term in duration. The Company does not designate these forward contracts as hedging instruments pursuant to ASC 815, Derivatives and Hedging. Accordingly, changes in the fair value of these foreign currency forward contracts are recognized in “Other expense, net” in the Consolidated Statements of Operations and are largely offset by the changes in the fair value of the assets or liabilities being hedged. The balance sheet classification for the fair value of these forward contracts is other current assets for forward contracts in an unrealized gain position and other current liabilities for forward contracts in an unrealized loss position. Foreign currency forward contracts’ losses recognized during the year ended December 31, 2023 were $0.2 million. Foreign currency forward contracts’ gains recognized during the years ended December 31, 2022 and 2021, were $0.3 million and $0.7 million, respectively. The U.S. dollar equivalents of all outstanding notional amounts of foreign currency forward contracts were as follows: As of December 31, (in thousands) 2023 2022 Purchase $ 54,169 $ 7,971 While the Company’s arrangements with its counterparties allow for net settlement, which is designed to reduce credit risk by permitting net settlement with the same counterparty, the Company recognizes all derivative instruments in the Consolidated Balance Sheets on a gross basis. As of December 31, 2023, gross fair values of derivative assets and liabilities, recorded as components of “Prepaid expenses and other current assets” and “Other current liabilities” wer e $0.2 million and $0.4 million, respectively, in the Consolidated Balance Sheets. Gross fair values of derivative assets and liabilities as of December 31, 2022 were immaterial. In connection with foreign currency derivatives entered in Israel, the Company’s subsidiaries in Israel are required to maintain a compensating balance with their bank at the end of each month. The compensating balance arrangements do not legally restrict the use of cash. As of December 31, 2023 and 2022, the total compensating balance maintained was $1.0 million.

FAIR VALUE MEASUREMENTS

FAIR VALUE MEASUREMENTS	12 Months Ended
FAIR VALUE MEASUREMENTS	Dec. 31, 2023
Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	FAIR VALUE MEASUREMENTS The applicable accounting guidance establishes a framework for measuring fair value and requires disclosure about the fair value measurements of assets and liabilities. This guidance defines fair value as the exchange price that would be received for an asset or paid to transfer a liability, in the principal or most advantageous market for the asset or liability, in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. This guidance requires the Company to classify and disclose assets and liabilities measured at fair value on a recurring basis, as well as fair value measurements of assets and liabilities measured on a nonrecurring basis in periods subsequent to initial measurement, in a three-tier fair value hierarchy as follows: • Level 1 - Observable inputs that reflect quoted prices for identical assets or liabilities in active markets. • Level 2 - Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. • Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. The carrying value of the Company’s financial instruments, including cash equivalents, accounts receivable, accounts payable and accrued liabilities, approximate fair value due to their short maturities. The following table sets forth the fair value of the Company’s financial assets and liabilities measured at fair value on a recurring basis based on the three-tier fair value hierarchy: December 31, 2023 December 31, 2022 ( in thousands ) Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Total Cash equivalents Money market funds $ 23,683 $ — $ — $ 23,683 $ — $ — $ — $ — Prepaid and other current assets Derivative assets $ — $ 194 $ — $ 194 $ — $ — $ — $ — Total assets $ 23,683 $ 194 $ — $ 23,877 $ — $ — $ — $ — Accrued and other current liabilities Derivative liabilities $ — $ 384 $ — $ 384 $ — $ 33 $ — $ 33 Total liabilities $ — $ 384 $ — $ 384 $ — $ 33 $ — $ 33 The Company's financial instruments not measured at fair value on a recurring basis were as follows: December 31, 2023 December 31, 2022 Carrying Fair Value Carrying Fair Value ( in thousands ) Value Level 1 Level 2 Level 3 Value Level 1 Level 2 Level 3 2024 Notes $ 114,880 $ — $ 177,405 $ — $ 113,981 $ — $ 181,139 $ — French and other loans $ 15,413 $ — $ 15,413 $ — $ 11,161 $ — $ 11,161 $ — The fair value of the Company’s Notes is influenced by interest rates, the price of the Company’s common stock and stock market volatility. The difference between the carrying value and the fair value is primarily due to the spread between the conversion price and the market value of the shares underlying the conversion as of each respective balance sheet date. The Company’s French and other loans are classified within Level 2 because these borrowings are not actively traded and the majority of them have a variable interest rate structure based upon market rates currently available to the Company for debt with similar terms and maturities; therefore, the carrying value of these debts approximate its fair value. Refer to Note 11, “Convertible Notes and Other Debts,” for additional information. During the years ended December 31, 2023, 2022, and 2021, there were no nonrecurring fair value measurements of assets and liabilities subsequent to initial recognition.

The Company generally does not require collateral and performs ongoing credit evaluations of its customers and provides for expected losses. The Company maintains an allowance for expected credit losses based upon the expected collectability of its accounts receivable. The expectation of collectability is based on the Company’s review of credit profiles of customers, contractual terms and conditions, current economic trends and historical payment experience. The Company offers return rights which are specifically identified and accrued for as sales returns at the end of the period.

Debt Disclosure [Abstract]
CONVERTIBLE NOTES AND OTHER DEBTS	CONVERTIBLE NOTES AND OTHER DEBTS 4.375% Convertible Senior Notes due 2022 (the “2022 Notes”) In June 2020, the Company issued the 2022 Notes with an aggregate principal amount of $37.7 million in a non-cash exchange for its 2020 Notes with an equal principal amount pursuant to an indenture, dated June 2, 2020 (the “2022 Notes Indenture”), by and between the Company and U.S. Bank Trust Company, National Association (as successor in interest to U.S. Bank National Association), as trustee. The 2022 Notes bore interest at a rate of 4.375% per year, payable in cash on June 1 and December 1 of each year. The 2022 Notes matured on December 1, 2022. The 2022 Notes were initially convertible into cash, shares of the Company’s common stock, or a combination thereof, at the Company’s election, at an initial conversion rate of 173.9978 shares of the Company’s common stock per $1,000 principal amount of the 2022 Notes (which is equivalent to an initial conversion price of approximately $5.75 per share). Pursuant to the supplemental indenture entered into by the Company and the trustee during the fourth quarter of fiscal 2021, the Company made an irrevocable election to settle the principal amounts of the 2022 Notes solely with cash and may pay or deliver, as the case may be, any conversion value greater than the principal amount in cash, shares of the Company’s common stock or a combination thereof, at the Company’s election. The conversion rate, and thus the effective conversion price, was adjustable under certain circumstances, including in connection with conversions made following certain fundamental changes and under other circumstances as set forth in the 2022 Notes Indenture. As discussed in the Note 2. “Recent Accounting Pronouncements”, effective January 1, 2022, the Company adopted ASU 2020-06 using the modified retrospective method and, as a result, accounted for the Convertible debt as a single liability measured at amortized cost. Prior to maturity date, the entire principal balance of $37.7 million was converted by holders of the 2022 Notes. In accordance with provisions of the 2022 Notes Indenture and the aforementioned supplemental indenture, conversions were settled in a combination of cash and the Company’s common Stock. The principal amount of $37.7 million that matured on December 1, 2022 was paid in cash. The conversion value greater than the principal amount was delivered in 3.9 million shares of the Company’s common stock. The following table presents interest expense recognized for the 2022 Notes: (in thousands) Year Ended December 31, 2023 2022 2021 Contractual interest expense $ — $ 1,511 $ 1,648 Amortization of debt discount — — 685 Amortization of debt issuance costs — 257 214 Total interest expense recognized $ — $ 1,768 $ 2,547 2.00% Convertible Senior Notes due 2024 (the “2024 Notes”) In September 2019, the Company issued $115.5 million of the 2024 Notes pursuant to an indenture (the “2024 Notes Indenture”), dated September 13, 2019, by and between the Company and U.S. Bank Trust Company, National Association (as successor in interest to U.S. Bank National Association), as trustee. The 2024 Notes bear interest at a rate of 2.00% per year, payable semi-annually on March 1 and September 1 of each year, beginning March 1, 2020. The 2024 Notes will mature on September 1, 2024, unless earlier repurchased by the Company, redeemed by the Company or converted pursuant to their terms. The 2024 Notes were initially convertible into cash, shares of the Company’s common stock, or a combination thereof, at the Company’s election, at an initial conversion rate of 115.5001 shares of the Company’s common stock per $1,000 principal amount of the 2024 Notes (which is equivalent to an initial conversion price of approximately $8.66 per share). Pursuant to the supplemental indenture entered into by the Company and the trustee during the fourth quarter of the fiscal year ended December 31, 2021, the Company made an irrevocable election to settle the principal amounts of the 2024 Notes solely with cash and may pay or deliver, as the case may be, any conversion value greater than the principal amount in cash, shares of the Company’s common stock or a combination thereof, at the Company’s election. The conversion rate, and thus the effective conversion price, may be adjusted under certain circumstances, including in connection with conversions made following certain fundamental changes or a notice of redemption and under other circumstances, in each case, as set forth in the 2024 Notes Indenture. The 2024 Notes will be convertible at certain times and upon the occurrence of certain events in the future, in each case, specified in the 2024 Notes Indenture. Further, on or after June 1, 2024, until the close of business on the scheduled trading day immediately preceding the maturity date, holders of the 2024 Notes may convert all or a portion of their 2024 Notes regardless of these conditions. The 2024 Notes are recorded at face value less unamortized debt issuance costs. Amortization costs are reported as a component of interest expense and are computed using the effective interest method. As the 2024 Notes mature within the next twelve months, they are classified as “Convertible debt, current” on the Consolidated Balance Sheet as of December 31, 2023. The following table presents the components of the 2024 Notes: As of December 31, (in thousands, except for years and percentages) 2023 2022 Liability: Principal amount $ 115,500 $ 115,500 Less: Debt issuance costs, net of amortization (620) (1,519) Carrying amount $ 114,880 $ 113,981 The following table presents interest expense recognized for the 2024 Notes: Year Ended December 31, (in thousands) 2023 2022 2021 Contractual interest expense $ 2,312 $ 2,312 $ 2,312 Amortization of debt discount — — 4,718 Amortization of debt issuance costs 898 874 641 Total interest expense recognized $ 3,210 $ 3,186 $ 7,671 Other Debts The Company has a variety of debt and credit facilities primarily in France to satisfy the financing requirements of the operations of its French subsidiary.

(2) Refer to the below section “Relief Loans” for the description of these loans. The table below presents the future minimum repayments of other debts as of December 31, 2023 (in thousands): Year ending December 31, 2024 $ 4,918 2025 5,238 2026 5,257 Total $ 15,413 Relief Loans In June 2020, Harmonic France was granted a loan from Société Générale S.A. (the “SG Loan”) in the aggregate amount of 5 million Euros, pursuant to a state guarantee program introduced in March 2020 to provide relief to companies from the financial consequences of the COVID-19 pandemic. The SG Loan was initially maturing in June 2021. During 2021, SG Loan maturity was extended to June 2026. The SG loan bears an effective interest rate of 0.51% per annum payable annually and may be repaid at any time prior to maturity with no repayment penalties. There are no restrictions on the use of funds from the SG Loan. The purpose of the funds from the SG Loan is to allow the preservation of activity and employment in France. As of December 31, 2023, there was $4.1 million outstanding under the loan, of which $1.4 million was recorded in “Other debts, current” and $2.7 million was recorded in “Other debts, non-current” in the Consolidated Balance Sheets. Line of Credit On December 21, 2023, the Company entered into a five-year Credit Agreement (the “Credit Agreement”), by and among the Company, certain subsidiaries of the Company from time to time party thereto, the lenders from time to time party thereto, and Citibank, N.A., as administrative agent for the lenders. The Credit Agreement provides for a secured revolving loan facility in an aggregate principal amount of up to $120.0 million (the “Revolving Facility”), with a $10.0 million sublimit for the issuance of letters of credit, and a secured delayed term loan facility in an aggregate principal amount of up to $40.0 million (the “Term Facility”). The Credit Agreement refinances and replaces the Company’s prior credit agreement, dated as of December 19, 2019, as amended, with JPMorgan Chase Bank, N.A., as lender. The proceeds of the loans under the Revolving Facility may be used for general corporate purposes. To the extent drawn, the proceeds of the loans under the Term Facility must be used to repurchase, redeem, acquire or otherwise settle the 2024 Notes. The Company may borrow term loans under the Term Facility in up to three drawings through September 1, 2024, on which date any undrawn commitments under the Term Facility expire. The Revolving Facility and Term Facility mature on December 21, 2028. Loans under the Revolving Facility and Term Facility will bear interest, at the Company’s election, at a floating rate per annum equal to either (a) a base rate, defined as the greatest of (i) the prime rate then in effect, (ii) the federal funds rate then in effect, plus 0.50%, or (iii) an adjusted term SOFR rate determined on the basis of a one-month interest period, plus 1.00%, in each case, plus a margin of between 1.00% to 1.75% (“Base Rate Loans”); and (b) an adjusted term SOFR rate (based on one, three or six month interest periods), plus a margin of between 2.00% to 2.75% (“Adjusted Term SOFR Loans”). The applicable margin in each case is determined based on the Company’s consolidated net leverage ratio. Interest is payable quarterly in arrears, in the case of Base Rate Loans, and at the end of the applicable interest period, but at least every three months, in the case of Adjusted Term SOFR Loans. The Company incurred $1.3 million in origination fee related to the Credit Agreement and this origination fee is being amortized over the term of the Credit Agreement. The Company is also obligated to pay other closing fees, commitment fees and letter of credit fees customary for a credit agreement of this size and type. The obligations under the Credit Agreement are required to be guaranteed by certain of the Company’s material subsidiaries and secured by substantially all of the assets of the Company and such subsidiary guarantors. The Credit Agreement contains customary affirmative and negative covenants, including covenants limiting the ability of the Company and its subsidiaries to, among other things, grant liens, incur debt, make acquisitions and other investments, undergo certain fundamental changes, dispose of assets, make certain restricted payments, enter into transactions with affiliates, and enter into burdensome agreements, in each case, subject to limitations and exceptions set forth in the Credit Agreement. The Company is also required to maintain compliance with a maximum consolidated net leverage ratio and a minimum fixed charge coverage ratio, in each case, determined in accordance with the terms of the Credit Agreement. As of December 31, 2023, the Company was in compliance with the covenants under the Credit Agreement. As of December 31, 2023, there were no borrowings under the Credit Agreement outstanding and approximately $0.2 million of letters of credit outstanding under the Credit Agreement.

EMPLOYEE BENEFIT PLANS	Dec. 31, 2023
Share-Based Payment Arrangement [Abstract]
EMPLOYEE BENEFIT PLANS	EMPLOYEE BENEFIT PLANS Equity Award Plans 1995 Stock Plan The 1995 Stock Plan provides for the grant of incentive stock options, non-statutory stock options and restricted stock units (“RSUs”). Incentive stock options may be granted only to employees. All other awards may be granted to employees and non-employees. Under the terms of the 1995 Stock Plan, no incentive stock option or non-statutory stock option may be granted in the ordinary course of business with a per share exercise price that is less than 100% of the fair value of the Company’s common stock on the date of grant. RSUs have no exercise price. Both options and RSUs vest over a period of time as determined by the Company’s Board of Directors (the “Board”), generally two certain financial and non-financial operating goals of the Company (performance-based RSUs, or “PRSUs”), or where vesting is dependent on performance of the Company’s total shareholder return (“TSR”) relative to the TSR of the NASDAQ Telecommunication Index (market-based RSUs, or “MRSUs” ). The fair value of PRSUs is estimated on the date of grant based on the market value of our common stock. If the performance goals are not met as of the end of the performance period, no compensation expense is recognized and any previously recognized compensation expense is reversed. The expected cost is based on the portion of the awards that is probable to vest and is reflected over the service period. The fair value of MRSUs subject to targeted levels of relative TSR is estimated on the date of grant using a Monte Carlo simulation model. Compensation expens e is recognized based upon the assumption of 100% achievement of the TSR goal and will not be reversed even if the threshold level of TSR is never achieved and is reflected over the service period . During the fiscal year 2023, the Company granted 268,704 and 236,749 shares of PRSUs and MRSUs, respectively. As of December 31, 2023, an aggregate of 8,537,211 shares of common stock were reserved for issuance under the 1995 Stock Plan, of which 5,481,584 shares remained available fo r future grants. 2002 Director Plan The 2002 Director Plan provides for the grant of non-statutory stock options and RSUs to non-employee directors of the Company. Under the terms of the 2002 Director Plan, no non-statutory stock option may be granted with a per share exercise price that is less than 100% of the fair value of the Company’s common stock on the date of grant. RSUs have no exercise price. Both options and RSUs vest over a period of time as determined by the Board, generally one year for RSUs and three years for options, and options expire seven years from the date of grant. As of December 31, 2023, an aggregate o f 637,671 shares of common stock were reserved for issuance under the 2002 Director Plan, of which 451,077 shares remained available fo r future grants. Employee Stock Purchase Plan The 2002 Employee Stock Purchase Plan (“ESPP”) provides for the issuance of share purchase rights to employees of the Company. The ESPP is intended to qualify as an “employee stock purchase plan” under Section 423 of the Internal Revenue Code. The ESPP enables employees to purchase shares at 85% of the fair market value of the Common Stock at the beginning or end of the offering period, whichever is lower. Offering periods generally begin on the first trading day on or after January 1 and July 1 of each year. Employees may participate through payroll deductions of 1% to 10% of their earnings. In the event that there are insufficient shares in the plan to fully fund the issuance, the available shares will be allocated across all participants based on their contributions relative to the total contributions received for the offering period. The Company’s stockholders approved an amendment to the ESPP Plan at the 2023 Annual Meeting to increase the number of shares of common stock reserved for issuance thereunder by 650,000 shares. As of December 31, 2023, 633,932 shares were reserved for future purchases by eligible employees. Under the ESPP, 733,030, 817,243 and 1,024,244 shares were issued during fiscal 2023, 2022 and 2021, respectively, representing $6.6 million, $5.9 million and $5.1 million in contributions. Stock Options All stock options were fully vested and exercised as of December 31, 2022. No stoc k options were granted in 2023. Restricted Stock Units (in thousands, except per share amounts) Number Weighted Average Balance at December 31, 2022 3,499 $ 8.93 Granted 2,539 13.65 Vested (2,516) 8.96 Forfeited (280) 9.40 Balance at December 31, 2023 3,242 $ 12.42 The fair value of RSUs vested during the years ended December 31, 2023, 2022 and 2021 was $22.5 million , $22.4 million and $18.3 million, respectively. Share-based Compensation Cost The following table sets forth the detailed allocation of the share-based compensation expense which was included in the Company’s Consolidated Statements of Operations: Year Ended December 31, (in thousands) 2023 2022 2021 Share-based compensation expense included in: Cost of revenue $ 2,348 $ 2,233 $ 2,345 Research and development expense 7,889 7,519 7,164 Selling, general and administrative expense 17,092 15,460 14,547 Total $ 27,329 $ 25,212 $ 24,056 Share-based compensation expense by type of award: RSUs $ 19,863 $ 17,786 $ 14,573 PRSUs 3,398 3,865 6,231 MRSUs 1,705 1,558 1,304 Employee stock purchase rights under ESPP 2,363 2,003 1,948 Total $ 27,329 $ 25,212 $ 24,056 As of December 31, 2023, total unrecognized share-based compensation cost related to unvested RSUs was $26.3 million and is expected to be recognized over a weighted-average period of approximately 1.6 years. French Pension Plan Under French law, the Company’s subsidiaries in France are obligated to make certain payments to their employees upon their retirement from the Company. These payments are based on the retiring employee’s salary for a number of months that varies according to the employee’s period of service and position. Salary used in the calculation is the employee’s average monthly salary for the twelve months prior to retirement. The payments are made in one lump-sum at the time of retirement. The French pension plan is unfunded and there are no contributions to the plan required by related laws or funding regulations. No required contributions are expected in fiscal 2024, but the Company, at its discretion, may make contributions to the defined benefit plan. The Company’s defined benefit pension obligations are measured annually as of December 31. The present value of these lump-sum payments is determined on an actuarial basis and the actuarial valuation considers the employees’ age and period of service with the Company, projected mortality rates, mobility rates, increases in salaries and a discount rate. The Company’s pension obligations as of December 31, 2023 and 2022, and the changes to the Company’s pension obligations for each of those years, were as follows: (in thousands) 2023 2022 Projected benefit obligation: Balance at January 1 $ 5,283 $ 6,003 Service cost 217 259 Interest cost 169 50 Actuarial gains (25) (626) Benefits paid (275) (107) Foreign currency translation adjustment 227 (296) Balance at December 31 $ 5,596 $ 5,283 Presented on the Consolidated Balance Sheets as: Current portion (included in “Accrued and other current liabilities”) $ 33 $ 242 Long-term portion (included in “Other non-current liabilities”) $ 5,563 $ 5,041 The table below presents the components of net periodic benefit costs: Year Ended December 31, (in thousands) 2023 2022 2021 Service cost $ 217 $ 259 $ 272 Interest cost 169 50 20 Net periodic benefit cost included in result of operations $ 386 $ 309 $ 292 The following assumptions were used in determining the Company’s pension obligation: As of December 31, 2023 2022 Discount rate 3.8 % 3.3 % Mobility rate 6.2 % 6.6 % Salary progression rate 3.0 % 3.0 % The Company evaluates the discount rate assumption annually. The discount rate is determined using the average yields on high-quality fixed-income securities that have maturities consistent with the timing of benefit payments. The Company also evaluates other assumptions related to demographic factors, such as retirement age, mortality rates and turnover periodically, updating them to reflect experience and expectations for the future. The mortality assumption related to the Company’s defined benefit pension plan used the most current mortality tables published by the French National Institute of Statistics and Economic Studies. As of December 31, 2023, future benefits expected to be paid in each of the next five years, and in the aggregate for the five-year period thereafter are as follows (in thousands): Year ending December 31, 2024 $ 33 2025 154 2026 180 2027 399 2028 797 2029 – 2033 4,210 Total $ 5,773 Valuation Assumptions The Company estimates the fair value of stock purchase rights under the ESPP using a Black-Scholes option valuation model. The value of the stock purchase rights under the ESPP consists of: (1) the 15% discount on the purchase of the stock; (2) 85% of the fair value of the call option; and (3) 15% of the fair value of the put option. The call option and put option were valued using the Black-Scholes option pricing model. At the date of grant, the Company estimated the fair value of each stock purchase right granted under the ESPP using the following weighted average assumptions: Year Ended December 31, 2023 2022 2021 Expected term (in years) 0.50 0.50 0.50 Volatility 46 % 47 % 45 % Risk-free interest rate 5.2 % 1.4 % 0.1 % Expected dividends 0.0 % 0.0 % 0.0 % The expected term of the stock purchase right under ESPP represents the period of time from the beginning of the offering period to the purchase date. The Company uses its historical volatility for a period equivalent to the expected term to estimate the expected volatility. The risk-free interest rate that the Company uses in the Black-Scholes option valuation model is based on U.S. Treasury zero-coupon issues with remaining terms similar to the expected term. The Company has not paid and does not plan to pay any cash dividends in the foreseeable future. The estimated weighted-average fair value per share of stock purchase rights under the ESPP, granted for the years ended December 31, 2023, 2022 and 2021 was $4.23, $2.91 and $2.24, respectively.

The Company’s effective income tax rate differs from the U.S. federal statutory rate primarily due to geographical mix of income and losses, valuation allowance release on U.S. federal and certain state deferred tax assets, and income taxes on earnings from operations in foreign tax jurisdictions. The Company’s effective income tax rate may be affected by changes in its interpretations of tax laws and tax agreements in any given jurisdiction, changes in geographical mix of income and expense, and changes in management's assessment of matters such as the ability to realize deferred tax assets, as well as one-time discrete items. During fiscal 2023, the Company recorded a one-time benefit of $67.7 million due to the release of the valuation allowance on deferred tax assets in U.S. Federal and state jurisdictions due to its improved earnings in recent years and projected earnings. The components of deferred taxes are as follows: As of December 31, (in thousands) 2023 2022 Deferred tax assets: Reserves and accruals $ 24,908 $ 27,376 Net operating loss carryforwards 14,376 16,032 Research and development credit carryforwards 30,117 28,952 Deferred stock-based compensation 1,863 1,376 Intangibles 5,651 6,384 Operating lease liabilities 6,216 7,423 Capitalized research and development expenses 64,075 36,210 Other 3,110 1,139 Gross deferred tax assets 150,316 124,892 Valuation allowance (37,084) (101,020) Gross deferred tax assets after valuation allowance 113,232 23,872 Deferred tax liabilities: Depreciation (3,506) (5,971) Operating lease right-of-use assets (5,019) (6,125) Gross deferred tax liabilities (8,525) (12,096) Net deferred tax assets $ 104,707 $ 11,776 The following table summarizes the activities related to the Company’s valuation allowance: Year Ended December 31, (in thousands) 2023 2022 2021 Balance at beginning of period $ 101,020 $ 90,247 $ 99,585 Additions 477 10,773 310 Deductions (64,413) — (9,648) Balance at end of period $ 37,084 $ 101,020 $ 90,247 Management regularly assesses the ability to realize deferred tax assets recorded based upon the weight of available evidence, including such factors as recent earnings history and expected future taxable income on a jurisdiction-by-jurisdiction basis. In 2023, the Company determined the deferred tax assets in the U.S federal and certain state jurisdictions would more-likely-than-not be realizable and released the valuation allowance against those assets accordingly. In the event the Company changes its determination as to the amount of realizable deferred tax assets, the Company will adjust its valuation allowance with a corresponding impact to the provision for income taxes in the period in which such determination is made. As of December 31, 2023, the Company had $89.3 million and $28.7 million of foreign and U.S. state net operating loss (“NOL”) carryforwards, respectively. The Company has now fully utilized their available U.S. federal NOLs. Certain foreign NOLs expire beginning in 2026, if not utilized, while the majority of the foreign NOLs carryforward indefinitely. Certain U.S. states NOL carryforward expires at various dates beginning in 2027, if not utilized. As of December 31, 2023, the Company had U.S. federal and California state tax credit carryforwards of $1.7 million and $37.0 million, respectively. If not utilized, the U.S. federal tax credit carryforwards will begin to expire in 2031, while the California tax credit carryforward will not expire. In the event the Company experiences an ownership change within the meaning of Section 382 of the Internal Revenue Code (“IRC”), the Company’s ability to utilize net operating losses, tax credits and other tax attributes may be limited. The Company has not provided U.S. state income taxes and foreign withholding taxes, on approximately $58.8 million of cumulative earnings for certain non-U.S. subsidiaries, because such earnings are intended to be indefinitely reinvested. Determination of the amount of unrecognized deferred tax liability for temporary differences related to investments in these non-U.S. subsidiaries that are essentially permanently in duration is not practicable. The Company applies the provisions of the applicable accounting guidance regarding accounting for uncertainty in income taxes, which require application of a more-likely-than-not threshold to the recognition and derecognition of uncertain tax positions. If the recognition threshold is met, the applicable accounting guidance permits the recognition of a tax benefit measured at the largest amount of such tax benefit that, in the Company’s judgment, is more than fifty percent likely to be realized upon settlement. It further requires that a change in judgment related to the expected ultimate resolution of uncertain tax positions to be recognized in earnings in the period in which such determination is made. The Company will continue to review its tax positions and provide for, or reverse, unrecognized tax benefits as issues arise. As of December 31, 2023, the Company had $12.5 million of unrecognized future tax benefits. Of these, $5.8 million would favorably impact the effective tax rate in future periods if recognized, and $6.7 million will have no or minimal impact on the effective tax rate in future periods if recognized due to a valuation allowance on such unrecognized tax benefits. The following table summarizes the activities related to the Company’s gross unrecognized tax benefits: Year Ended December 31, (in millions) 2023 2022 2021 Balance at beginning of period $ 11.1 $ 13.8 $ 17.6 Increase in balance related to tax positions taken during current year 0.4 0.3 0.3 Decrease in balance as a result of a lapse of the applicable statutes of limitations — — (0.2) Increase in balance related to tax positions taken during prior years 1.0 — — Decrease in balance related to tax positions taken during prior years — (3.0) (3.9) Balance at end of period $ 12.5 $ 11.1 $ 13.8 The Company recognizes interest and penalties related to unrecognized tax positions in income tax expense on the Consolidated Statements of Operations. The net interest and penalties charges recorded for the years ended December 31, 2021 through 2023, were not material. The 2019 through 2022 tax years generally remain subject to examination by U.S. federal and most state tax authorities.Net operating losses generated on a tax return basis by the Company for the 2015 to 2020 tax years and research and development credits for 2011 to 2022 tax years remain open to examination. In addition, the Company remains subject to income tax examination for several other jurisdictions, including in Switzerland for years after 2018, Israel for years after 2019, and France for years after 2016.

NET INCOME PER SHARE	Dec. 31, 2023
Earnings Per Share [Abstract]
NET INCOME PER SHARE	NET INCOME PER SHARE Basic earnings per share is computed by dividing net income for the period by the weighted average number of common shares outstanding during the period. Diluted earnings per shares is calculated by dividing net income by the weighted average number of common shares and potentially dilutive securities outstanding during the period using the treasury stock method for the Company’s stock options, restricted stock units, and shares issuable under the ESPP, and the if-converted method for the 2024 Notes. As noted in Note 11, “Convertible Notes and Other Debts,” the principal amount of the 2024 Notes will be settled in cash. Therefore, for the purpose of calculating diluted net income per share, it will be assumed that the conversion spread value will be settled in shares.

Segment Reporting [Abstract]
SEGMENT INFORMATION, GEOGRAPHIC INFORMATION AND CUSTOMER CONCENTRATION	SEGMENT INFORMATION, GEOGRAPHIC INFORMATION AND CUSTOMER CONCENTRATION Segment Information Operating segments are defined as components of an enterprise that engage in business activities for which separate financial information is available and evaluated by the Company’s Chief Operating Decision Maker (the “CODM”), which for the Company is its Chief Executive Officer, in deciding how to allocate resources and assess performance. Based on the internal reporting structure, the Company consists of two operating segments: Video and Broadband. The operating segments were determined based on the nature of the products offered. The Video segment provides video processing, production and playout solutions and services worldwide to broadcast and media companies, new streaming media companies, broadband operators, and satellite and telco Pay-TV service providers. The Broadband segment provides broadband access solutions and related services to broadband operators globally. A measure of assets by segment is not applicable as segment assets are not included in the discrete financial information provided to the CODM. The following table provides summary financial information by reportable segment: Year Ended December 31, ( in thousands ) 2023 2022 2021 Video Revenue $ 219,425 $ 274,189 $ 288,507 Operating income (loss) (8,741) 22,322 28,460 Broadband Revenue $ 388,482 $ 350,768 $ 218,642 Operating income 64,575 52,283 15,599 Total Revenue $ 607,907 $ 624,957 $ 507,149 Operating income $ 55,834 $ 74,605 $ 44,059 A reconciliation of the Company’s consolidated segment operating income to consolidated income before income taxes is as follows: Year Ended December 31, (in thousands ) 2023 2022 2021 Total consolidated segment operating income $ 55,834 $ 74,605 $ 44,059 Unallocated corporate expenses (1) (6,333) (3,874) (681) Stock-based compensation (27,329) (25,212) (24,062) Amortization of intangibles — — (507) Consolidated income from operations 22,172 45,519 18,809 Non-operating expense, net (3,031) (1,034) (9,938) Income before income taxes $ 19,141 $ 44,485 $ 8,871 (1) Together with amortization of intangibles and stock-based compensation, the Company does not allocate restructuring and related charges and certain other non-recurring charges to the operating income (loss) for each segment because management does not include this information in the measurement of the performance of the operating segments. Disaggregation of Revenues The following table provides a summary of total revenues disaggregated by type: Year Ended December 31, (in thousands) 2023 2022 2021 Product sales $ 396,682 $ 423,858 $ 343,406 Professional services 39,196 49,948 26,361 Total Appliance and integration 435,878 473,806 369,767 SaaS 50,888 34,665 21,266 Support services 121,141 116,486 116,116 Total SaaS and services 172,029 151,151 137,382 Total revenue $ 607,907 $ 624,957 $ 507,149 The following table provides a summary of total net revenues by geographic region: Net revenue: Year Ended December 31, (in thousands) 2023 2022 2021 United States (1) $ 408,951 $ 393,991 $ 282,912 Other countries (1) 198,956 230,966 224,237 Total $ 607,907 $ 624,957 $ 507,149 (1) Revenue is attributed to countries based on the location of the customer.

The credit facility is secured by a $2.2 million indemnity issued by the parent company. There were no amounts outstanding under this credit facility as of December 31, 2023 and 2022. On December 21, 2023, the Company entered into a Credit Agreement, with Citibank, N.A., as administrative agent for the lenders. The Credit Agreement refinances and replaces the Company’s prior credit agreement, dated as of December 19, 2019, as amended, with JPMorgan Chase Bank, N.A., as lender. As of December 31, 2023, there were no borrowings under the Credit Agreement outstanding and approximately $0.2 million of letters of credit outstanding under the Credit Agreement. The Company was in compliance with the covenants under the Credit Agreement as of December 31, 2023. Refer to Note 11, “Convertible Notes and other Debts” of the Notes to the Consolidated Financial Statements for additional information regarding the Credit Agreement. Indemnification The Company is obligated to indemnify its officers and its directors pursuant to its bylaws and contractual indemnity agreements. The Company also indemnifies some of its suppliers and most of its customers for specified intellectual property matters pursuant to certain contractual arrangements, subject to certain limitations. The scope of these indemnities varies, but, in some instances, includes indemnification for damages and expenses (including reasonable attorneys’ fees). There have been no amounts accrued in respect of the indemnification provisions through December 31, 2023.

Loss Contingency [Abstract]
LEGAL PROCEEDINGS	LEGAL PROCEEDINGS From time to time, the Company is involved in lawsuits as well as subject to various legal proceedings, claims, threats of litigation, and investigations in the ordinary course of business, including claims of alleged infringement of third-party patents and other intellectual property rights, commercial, employment, and other matters. The Company assesses potential liabilities in connection with each lawsuit and threatened lawsuits and accrues an estimated loss for these loss contingencies if both of the following conditions are met: information available prior to issuance of the financial statements indicates that it is probable that a liability has been incurred at the date of the financial statements and the amount of loss can be reasonably estimated. While certain matters to which the Company is a party specify the damages claimed, such claims may not represent reasonably probable losses. Given the inherent uncertainties of litigation, the ultimate outcome of these matters cannot be predicted at this time, nor can the amount of possible loss or range of loss, if any, be reasonably estimated.

SUMMARY OF SIGNIFICANT ACCOUN_2

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	Dec. 31, 2023
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying consolidated financial statements include those of Harmonic and its wholly-owned subsidiaries, after elimination of all intercompany accounts and transactions. The Company has reclassified certain amounts previously reported in its consolidated financial statements that were not material, to conform to the current presentation. The Company’s fiscal quarters are based on 13-week periods, except for the fourth quarter which ends on December 31.
Use of Estimates	Use of Estimates The preparation of consolidated financial statements in conformity with U.S. generally accepted accounting principles (“US GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. The Company’s reported financial positions or results of operations may be materially different under changed conditions or when using different estimates and assumptions, particularly with respect to significant accounting policies. If estimates or assumptions differ from actual results, subsequent periods are adjusted to reflect more current information.
Cash and Cash Equivalents	Cash and Cash Equivalents All highly liquid investments with an original maturity of three months or less at the date of purchase are considered cash equivalents. The carrying amount of cash and cash equivalents approximates fair value because of the short maturity of those instruments.
Credit Risk and Major Customers/Supplier Concentration	Credit Risk and Major Customers/Supplier Concentration Financial instruments which subject the Company to concentrations of credit risk consist primarily of cash, cash equivalents, and accounts receivable. Cash and cash equivalents are invested in short-term, highly liquid, investment-grade instruments, in accordance with the Company’s investment policy. The investment policy limits the amount of credit exposure to any one financial institution, commercial or governmental issuer. Certain of the components and subassemblies included in the Company’s products are obtained from a single source or a limited group of suppliers. Although the Company seeks to reduce dependence on those sole source and limited source suppliers, the partial or complete loss of certain of these sources could have at least a temporary adverse effect on the Company’s results of operations and damage customer relationships.
Revenue Recognition	Revenue Recognition The Company classifies its total revenue in two categories on the face of the statement of operations, “Appliance and integration” and “SaaS and service. Appliance and integration revenue includes revenue from the sale of hardware products and perpetual software licenses, as well as the associated professional services such as testing, design, installation, commissioning, and integration, collectively referred to as “professional services. These professional service agreements, associated with the sale of hardware products and perpetual software licenses, are typically of a short duration and are considered an important component of the appliance business by management. SaaS and service revenue include usage fees for the Company’s SaaS platform and support service revenue from its appliance-based customers. The Company applies the provisions of ASC 606, Revenue from Contracts with Customers (ASC 606) as a single standard for revenue recognition that applies to all of its hardware products, software licenses and services arrangements and generally require revenues to be recognized upon the transfer of control of promised goods or services provided to its customers, reflecting the amount of consideration the Company expects to receive for those goods or services. Pursuant to ASC 606, revenue is recognized upon the application of the following steps: • identification of the contract, or contracts, with a customer; • identification of the performance obligations in the contract; • determination of the transaction price; • allocation of the transaction price to each performance obligation in the contract; and • recognition of revenues when, or as, the contractual performance obligations are satisfied. Hardware and Software: Revenue from the sale of hardware and software products is recognized when control is transferred. For most of the Company’s product sales (including sales to distributors and system integrators), control is transferred at the time the product is shipped or delivery has occurred because the customer has significant risks and rewards of ownership of the asset and the Company has a present right to payment at that time. The Company’s agreements with the distributors and system integrators have terms which are generally consistent with the standard terms and conditions for the sale of the Company’s equipment to end users, and do not provide for product rotation or pricing allowances, as are typically found in agreements with stocking distributors. Shipping and handling costs are accounted for as a fulfillment cost and are recorded in “Cost of revenue” in the Company’s Consolidated Statements of Operations. Sales tax and other amounts collected on behalf of third parties are excluded from the transaction price. Professional services: Revenues from professional services are generally recognized as the services are performed. SaaS services: Revenue for SaaS service is recognized ratably over the contractual term as the customer simultaneously receives and consumes the benefit of the underlying service. Over-usage fees are recognized as revenue when consumed and are included in the transaction price of an arrangement as variable consideration. Support and maintenance. Support and maintenance services are satisfied ratably over time as the customer simultaneously receives and consumes the benefits of the services. Arrangements with Multiple Performance Obligations. The Company has revenue arrangements that include multiple performance obligations. The Company allocates the transaction price to all distinct performance obligations based on their relative standalone selling prices (“SSP”). The Company may exercise judgment when determining whether products and services are considered distinct performance obligations that should be accounted for separately versus together. The determination of SSP is generally based on the contractually stated, observable prices of the promised goods and services charged when sold separately to the customer. Where SSP is not directly observable, we determine the SSP using information which considers multiple factors including, but not limited to, major product groupings, gross margin objectives and pricing practices. Pricing practices taken into consideration include discounts offered and applicable price lists. Contract Balances . Deferred revenue represents the Company’s obligation to transfer goods or services to a customer for which the Company has received consideration (or an amount of consideration is due) from the customer. The Company’s payment terms vary by the type and location of its customer and the products or services offered. The term between invoicing and when payment is due is not significant. For certain products or services and customer types, the Company requires payment before the products or services are delivered to the customer. Contract costs. The incremental costs of obtaining a contract are capitalized if the costs are expected to be recovered. Costs that are recognized as assets are amortized on a straight-line basis over the period during which the related goods or services transfer to the customer. Costs incurred to fulfill a contract are capitalized if they are not covered by other relevant guidance, relate directly to a contract, will be used to satisfy future performance obligations, and are expected to be recovered.
Inventories	Inventories Inventories are stated at the lower of cost (determined on first-in, first-out basis) or net realizable value. The cost of inventories is comprised of material and manufacturing labor and overheads. The Company establishes provisions for excess and obsolete inventories to reduce such inventories to their estimated net realizable value after evaluation of historical sales, future demand and market conditions, expected product life cycles and current inventory levels. Such provisions are charged to cost of revenue in the Company’s Consolidated Statements of Operations.
Property and Equipment	Property and Equipment
Goodwill	Goodwill Goodwill is assigned to one or more reporting segments on the date of acquisition. We review our goodwill for impairment annually during our fourth quarter of each fiscal year and between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of any one of our reporting units below its respective carrying amount. The Company monitors changing business conditions as well as industry and economic factors, among others, for events which could trigger the need for an interim impairment analysis. In performing our goodwill impairment test, we first perform a qualitative assessment, which requires that we consider events or circumstances including macroeconomic conditions, industry and market considerations, cost factors, overall financial performance, changes in management or key personnel, changes in strategy, changes in customers, changes in the composition or carrying amount of a reporting segment’s net assets and changes in our stock price. If, after assessing the totality of events or circumstances, we determine that it is more likely than not that the fair values of our reporting segments are greater than the carrying amounts, then the quantitative goodwill impairment test is not performed. If the qualitative assessment indicates that the quantitative analysis should be performed, we then evaluate goodwill for impairment by comparing the fair value of each of our reporting segments to its carrying value, including the associated goodwill. To determine the fair values, we use the market approach based on comparable publicly traded companies in similar lines of businesses and the income approach based on estimated discounted future cash flows. Our cash flow assumptions consider historical and forecasted revenue, operating costs and other relevant factors.
Leases	Leases The Company determines if an arrangement is a lease at inception. Operating lease liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. The Company’s lease contracts do not provide an implicit borrowing rate; hence the Company determined the incremental borrowing rate based on information available at lease commencement to determine the present value of lease liability. Right-of-use (“ROU”) assets related to our operating lease liabilities are measured at lease inception based on the initial measurement of the lease liability, plus any prepaid lease payments and less any lease incentives. As of December 31, 2023, the Company has operating leases primarily consisting of facilities with remaining lease terms of 1 year to 9 years, some of which included the option to extend the term. Optional periods to extend the lease, including by not exercising a termination option, are included in the lease term when it is reasonably certain that the option will be exercised. The Company amortizes ROU assets as operating lease expense on a straight-line basis over the lease term. Operating leases are included in “Operating lease right-of-use assets”, “Operating lease liabilities, current”, and “operating lease liabilities, non-current” in the Consolidated Balance Sheets.
Foreign Currency	Foreign Currency The functional currency of the Company’s Israeli and Swiss subsidiaries is the U.S. dollar. All other foreign subsidiaries use the respective local currency as the functional currency. When the local currency is the functional currency, gains and losses from translation of these foreign currency financial statements into U.S. dollars are recorded as a separate component of other comprehensive income (loss) in stockholders’ equity. The Company’s foreign currency exposure is also related to its net position of monetary assets and monetary liabilities held by its foreign subsidiaries in their nonfunctional currencies. These monetary assets and liabilities are being remeasured into the subsidiaries’ respective functional currencies using exchange rates as of the balance sheet date. Such remeasurement gains and losses are included in “Other income (expense), net” in the Company’s Consolidated Statements of Operations.
Derivative Instruments	Derivative Instruments The Company enters into derivative instruments, primarily foreign currency forward contracts, to minimize the short-term impact of foreign currency exchange rate fluctuations on certain foreign currency denominated assets and liabilities as well as certain foreign currencies denominated expenses. The Company does not enter into derivative instruments for trading purposes and these derivatives generally have maturities within three months. The derivative instruments are recorded at fair value in prepaid expenses and other current assets or accrued and other current liabilities in the Company’s Consolidated Balance Sheets. The Company enters into derivative instruments to hedge existing foreign currency denominated assets or liabilities, the gains or losses on these hedges are recorded immediately in earnings to offset the changes in the fair value of the assets or liabilities being hedged.
Research and Development	Research and Development Research and development (“R&D”) costs are expensed as incurred and consist primarily of employee salaries and related expenses, contractors and outside consultants, supplies and materials, equipment depreciation and facilities costs, all associated with the design and development of new products and enhancements of existing products.
Restructuring and Related Charges	Restructuring and Related Charges The Company’s restructuring charges consist primarily of employee severance, one-time termination benefits related to the reduction of its workforce, and other costs. Liabilities for costs associated with a restructuring activity are recognized when the liability is incurred and are measured at fair value. One-time termination benefits are expensed at the date the entity notifies the employee, unless the employee must provide future service, in which case the benefits are expensed ratably over the future service period. Termination benefits are calculated based on regional benefit practices and local statutory requirements.
Warranty	Warranty The Company accrues for estimated warranty costs at the time of revenue recognition and records such accrued liabilities as part of cost of revenue. Management periodically reviews its warranty liability and adjusts the accrued liability based on the terms of warranties provided to customers, historical and anticipated warranty claims experience, and estimates of the timing and cost of warranty claims.
Advertising Expenses	Advertising Expenses
Stock-based Compensation	Stock-based Compensation The Company measures and recognizes compensation expense for all stock-based compensation awards made to employees, including stock options, restricted stock units (“RSUs”) and stock purchase rights under the Company’s Employee Stock Purchase Plan (“ESPP”), based upon the grant-date fair value of those awards. The Company recognizes the impact of forfeitures as they occur. The fair value of the Company’s stock options and stock purchase rights under ESPP is estimated at grant date using the Black-Scholes option pricing model. The fair value of the Company’s RSUs and performance-based RSUs (“PRSUs”) is calculated based on the market value of the Company’s stock at the grant date. The fair value of the Company’s market-based RSUs (“MRSUs”) is estimated using the Monte-Carlo valuation model with market vesting conditions. The Company recognizes the stock-based compensation for options, RSUs, MRSUs and stock purchase rights under ESPP on straight-line basis over the requisite service period, which is generally the vesting period. The Company recognizes the stock-based compensation for PRSUs based on the probability of achieving performance criteria defined in the PRSU agreements. The Company estimates the number of PRSUs ultimately expected to vest and recognizes expense using the graded vesting attribution method over the requisite service period. Changes in the estimates related to probability of achieving certain performance criteria and number of PRSUs expected to vest could significantly affect the related stock-based compensation expense from one period to the next.
Pension Plan	Pension Plan Under French law, the Company’s subsidiary in France is obligated to provide for a defined benefit plan to its employees upon their retirement from the Company. The Company’s defined benefit pension plan in France is unfunded. The Company records its obligations relating to the pension plans based on calculations which include various actuarial assumptions including employees’ age and period of service with the company; projected mortality rates, mobility rates and increases in salaries; and a discount rate. The Company reviews its actuarial assumptions on an annual basis as of December 31 (or more frequently if a significant event requiring remeasurement occurs) and modifies the assumptions based on current rates and trends when it is appropriate to do so. The effect of modifications to those assumptions is recorded in other comprehensive income (loss) and amortized to net periodic benefit cost over the expected remaining period of service of the covered employees using the corridor method. The Company believes that the assumptions utilized in recording its obligations under its pension plan are reasonable based on its experience, market conditions and input from its actuaries.
Income Taxes	Income Taxes The Company accounts for income taxes using the asset and liability method of accounting for income taxes. The Company calculates and provides for income taxes in each of the tax jurisdictions in which it operates. The deferred tax assets and liabilities are recognized for future tax consequences attributable to temporary differences between the financial statement carrying values of existing assets and liabilities and their respective tax bases and all operating losses carried forward, if any. Deferred tax assets and liabilities are measured using tax rates expected to apply to taxable income in the years in which the applicable temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates or tax status is recognized in the statements of income in the period in which the change is identified. Deferred tax assets are reduced by a valuation allowance if, based on available evidence, it is more likely than not that some portion or all of the deferred tax assets will not be realized. The Company is subject to examination of its income tax returns by various tax authorities on a periodic basis. The Company regularly assesses the likelihood of adverse outcomes resulting from such examinations to determine the adequacy of its provision for income taxes. The Company has applied the provisions of the applicable accounting guidance on accounting for uncertainty in income taxes, which requires application of a more-likely-than-not threshold to the recognition and de-recognition of uncertain tax positions. If the recognition threshold is met, the applicable accounting guidance permits the Company to recognize a tax benefit measured at the largest amount of tax benefit that, in the Company’s judgment, is more than 50% likely to be realized upon settlement. It further requires that a change in judgment related to the expected ultimate resolution of uncertain tax positions be recognized in earnings in the period of such change. The Company files annual income tax returns in multiple taxing jurisdictions around the world. A number of years may elapse before an uncertain tax position is audited and finally resolved. While it is often difficult to predict the final outcome or the timing of resolution of any particular uncertain tax position, the Company believes that its reserves for income taxes reflect the most likely outcome. The Company adjusts these reserves and penalties, as well as the related interest, in light of changing facts and circumstances. Changes in the Company’s assessment of its uncertain tax positions or settlement of any particular position could materially and adversely impact the Company’s income tax rate, operating results, financial position and cash flows. The Company has not provided U.S. state income taxes and foreign withholding taxes, on approximately $58.8 million of cumulative earnings for certain non-U.S. subsidiaries, because such earnings are intended to be indefinitely reinvested. Determination of the amount of unrecognized deferred tax liability for temporary differences related to investments in these non-U.S. subsidiaries that are essentially permanently in duration is not practicable.
Recently Adopted and Issued Accounting Pronouncements	Recently Adopted Accounting Pronouncements Recently Issued Accounting Pronouncement In November 2023, the FASB issued ASU No. 2023-07, Segment Reporting, which expands annual and interim disclosure requirements for reportable segments, primarily through enhanced disclosures about significant segment expenses. The updated standard is effective for our annual periods beginning in fiscal 2024 and interim periods beginning in the first quarter of fiscal 2025. Early adoption is permitted. The Company is currently evaluating the impact the new accounting standard will have on its segment reporting disclosures in the notes to the consolidated financial statements. In December 2023, the FASB issued ASU No. 2023-09, Improvements to Income Tax Disclosures. This ASU requires disaggregated information about a reporting entity’s effective tax rate reconciliation as well as additional information on income taxes paid. The ASU is effective on a prospective basis for annual periods beginning after December 15, 2024. Early adoption is also permitted for annual financial statements that have not yet been issued or made available for issuance. This ASU will result in the required additional disclosures being included in our consolidated financial statements, once adopted.
Fair Value Measurement	The applicable accounting guidance establishes a framework for measuring fair value and requires disclosure about the fair value measurements of assets and liabilities. This guidance defines fair value as the exchange price that would be received for an asset or paid to transfer a liability, in the principal or most advantageous market for the asset or liability, in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. This guidance requires the Company to classify and disclose assets and liabilities measured at fair value on a recurring basis, as well as fair value measurements of assets and liabilities measured on a nonrecurring basis in periods subsequent to initial measurement, in a three-tier fair value hierarchy as follows: • Level 1 - Observable inputs that reflect quoted prices for identical assets or liabilities in active markets. • Level 2 - Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. • Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.
Segment Reporting	Segment Information Operating segments are defined as components of an enterprise that engage in business activities for which separate financial information is available and evaluated by the Company’s Chief Operating Decision Maker (the “CODM”), which for the Company is its Chief Executive Officer, in deciding how to allocate resources and assess performance. Based on the internal reporting structure, the Company consists of two operating segments: Video and Broadband. The operating segments were determined based on the nature of the products offered. The Video segment provides video processing, production and playout solutions and services worldwide to broadcast and media companies, new streaming media companies, broadband operators, and satellite and telco Pay-TV service providers. The Broadband segment provides broadband access solutions and related services to broadband operators globally. A measure of assets by segment is not applicable as segment assets are not included in the discrete financial information provided to the CODM.
