Goodwill and Intangible Assets

Goodwill and Intangible Assets	9 Months Ended

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and intangible assets	Note 5 . Goodwill and Intangible Assets When the Company acquired the trade assets of Motorola Solutions, Inc.’s wireless point-to-point and point-to-multi-point businesses in 2011, the transaction generated goodwill and certain intangible assets. The goodwill associated with this transaction was recorded by Cambium Networks Corporation and allocated to Cambium Networks, Ltd. and Cambium Networks, Inc. using a revenue and asset allocation method. Although goodwill has been allocated to two operating subsidiaries, the Company operates as one operating segment and one reporting unit and therefore, goodwill is reported, and impairment testing performed, at the Cambium Networks Corporation consolidated level. There was no change in the carrying amount of goodwill during the three-month period ended September 30, 2022 (unaudited). The Company tests goodwill and intangible assets for impairment annually on December 31 and more frequently if impairment indicators exist. Accordingly, the Company performs quarterly qualitative assessments of significant events and circumstances such as a reporting unit’s historical and current results, assumptions regarding future performance, strategic initiatives and overall economic factors, including the impact of the current global outbreak of the coronavirus (or COVID-19) and macro-economic developments, to determine the existence of potential indicators of impairment and assess if it is more likely than not that the fair value of the reporting unit or intangible asset is less than their carrying value. If indicators of impairment are identified, a quantitative impairment test is performed. Qualitative assessments for the quarter did not indicate the existence of impairment indicators. Based on the operating results for the nine-month period ended September 30, 2022 and other considerations, the Company believes that it is more likely than not that the enterprise value for its one reporting unit and the fair value of intangibles is still greater than their carrying values. Accordingly, no goodwill impairment indicators were present at September 30, 2022 that would necessitate an interim impairment assessment. The useful life, gross carrying value, accumulated amortization, and net balance for each major class of definite-lived intangible assets at each balance sheet date were as follows (in thousands): December 31, 2021 September 30, 2022 Useful Life Gross Accumulated Net balance Gross Accumulated Net balance (unaudited) (unaudited) (unaudited) Unpatented 3 - 7 years $ 14,660 $ ( 14,555 ) $ 105 $ 14,660 $ ( 14,660 ) $ — Customer 5 - 18 years 19,300 ( 8,628 ) 10,672 19,300 ( 9,752 ) 9,548 Patents 7 years 11,300 ( 11,300 ) — 11,300 ( 11,300 ) — Trademarks 10 years 5,270 ( 5,270 ) — 5,270 ( 5,270 ) — Total $ 50,530 $ ( 39,753 ) $ 10,777 $ 50,530 $ ( 40,982 ) $ 9,548 Intangible assets are amortized over their expected useful life and none are expected to have a significant residual value at the end of their useful life. Intangible assets amortization expense was $ 0.6 million and $ 0.4 million for the three-month periods ended September 30, 2021 and 2022, respectively, and $ 1.7 million and $ 1.2 million for the nine-month periods ended September 30, 2021 and 2022, respectively.

On November 17, 2021, the Company borrowed $ 30.0 million as a Eurodollar Rate loan. Both the Term Facility and the Revolving Facility mature on November 17, 2026 . Interest accrues on the outstanding principal amount of the Term and Revolving Facilities on a quarterly basis and is equal to a base rate equal rate per annum determined by reference to the 1-month, 3-month or 6-month US Dollar LIBOR rate as selected by the Company, plus an applicable margin between 1.75 % to 2.25 % as determined by the Company’s performance as measured by the consolidated leverage ratio. At September 30, 2022, the applicable margin was 1.75 % and the effective interest rate on the term loan was 5.15 %. In addition to paying interest on the outstanding principal under the term loan facility, the Company is required to pay a quarterly commitment fee on the unutilized commitments under the revolving credit facility ranging from 0.20 % to 0.25 % as determined by the Company's performance as measured by the consolidated leverage ratio. The commitment fee was 0.20 % at September 30, 2022. The Company is also required to pay letter of credit fees on the maximum amount available to be drawn under all outstanding letters of credit in an amount equal to the applicable margin on LIBOR-based borrowings under the revolving credit facility on a per annum basis, payable in arrears, as well as fronting fees for the issuance of letters of credit and agency fees. Under the BofA Credit Agreement, commencing on March 31, 2022, the Company began making quarterly principal payments of $ 0.7 million, with the remaining principal due on maturity on November 17, 2026 . The Company is required to pay interest quarterly on the outstanding balance. The Company is permitted to voluntarily reduce the unutilized portion of the commitment amount and repay outstanding loans under the BofA Credit Agreement at any time without premium or penalty. Maturities on the external debt outstanding at September 30, 2022 is as follows (unaudited and in thousands): Year ending December 31, 2022 (October - December) $ 1,313 2023 2,625 2024 2,625 2025 2,625 2026 19,500 Total $ 28,688 Borrowings under the BofA Credit Agreement are secured by a first-priority lien on substantially all of the Company’s assets, the equity interests in certain of the Company’s subsidiaries, and any intercompany debt. The Credit Agreement contains certain customary affirmative and negative covenants that are usual and customary for companies with similar credit ratings. As of September 30, 2022, the Company was in compliance with all affirmative and negative covenants (unaudited). Net int erest expense, including bank charges and amortization of debt issuance costs on the external debt, was $ 0.7 million and $ 0.5 million for the three-month periods ended September 30, 2021 and 2022, respectively, and $ 3.2 million and $ 1.4 million for the nine-month periods ended September 30, 2021 and 2022, respectively. The nine-month period ended September 30, 2021 included $ 0.3 million of additional amortization of debt issuance costs associated with the excess cash flow payment of $ 19.6 million made in the second quarter of 2021. Expected Discontinuation of LIBOR In July 2017, the United Kingdom’s Financial Conduct Authority, or FCA, which regulates LIBOR, announced it will no longer compel banks to submit rates for the calculation of LIBOR after 2021. On December 31, 2021, the 1-week and 2-month US Dollar LIBOR ceased, but the remaining five US Dollar LIBOR tenors (overnight and 1-month, 3-month, 6-month and 12-month) will not cease until June 30, 2023 . The base interest rate on the Company’s BofA Credit Agreement may be determined by reference to the 1-month, 3-month or 6-month US Dollar LIBOR rate, as selected by the Company. The BofA Credit Agreement matures on November 17, 2026 , which is subsequent to the cessation of all tenors of the US Dollar LIBOR rate. The Company is evaluating the potential impact of the transition from LIBOR as an interest rate benchmark to other potential alternative reference rates, including SOFR. Eurodollar loans under the BofA Credit Agreement are currently indexed to the Eurodollar Rate (the rate equivalent to LIBOR). The BofA Credit Agreement contemplates the discontinuation of LIBOR and provides that a benchmark replacement rate shall be determined by reference to other applicate rates and additionally allows for the Company to switch to a Base Rate Loan, as defined in the BofA Credit Agreement. The Company will continue to actively assess the related opportunities and risks involved in this transition.

Share-based compensation	Note 9 . Share-based compensation 2019 Share incentive plan In June 2019, the Company’s Board of Directors adopted, and its shareholders approved, the 2019 Share Incentive Plan (“2019 Plan”). The 2019 Plan provides for the grant of incentive share options, nonqualified share options, share appreciation rights, restricted share awards (“RSAs”), restricted share units (“RSUs”), other share-based awards and performance awards. The share reserve under the 2019 Plan is automatically increased on the first day of each fiscal year, beginning with the fiscal year ended December 31, 2020 and continuing until, and including, the fiscal year ending December 31, 2029. The number of shares added annually is equal to the lowest of 1,320,000 shares, 5 % of the number of the Company’s shares outstanding on the first day of such fiscal year, or an amount determined by the Board of Directors. On February 25, 2022, the Company registered 1,320,000 additional shares that may be issued under the 2019 Plan. The Company’s employees, officers, directors, consultants, and advisors are eligible to receive awards under the 2019 Plan. Incentive share options, however, may only be granted to its employees. The following table summarizes changes in the number of shares available for grant under the Company’s equity incentive plans during the nine-month period ended September 30, 2022 (unaudited): Number of shares Available for grant at December 31, 2021 1,853,240 Added to 2019 Share Incentive Plan 1,320,000 RSUs granted ( 402,546 ) Options granted ( 963,000 ) Shares withheld in settlement of taxes and/or exercise price 43,109 Expirations 8,799 Forfeitures 115,493 Available for grant at September 30, 2022 1,975,095 Share-based compensation The following table shows total share-based compensation expense for the three-month and nine-month periods ended September 30, 2021 and 2022 (unaudited and in thousands): Three Months Ended September 30, Nine Months Ended September 30, 2021 2022 2021 2022 Cost of revenues $ 39 $ 56 $ 108 $ 163 Research and development 834 1,241 2,193 3,274 Sales and marketing 540 696 1,374 1,901 General and administrative 663 855 1,909 2,447 Total share-based compensation expense $ 2,076 $ 2,848 $ 5,584 $ 7,785 For the three-month periods ended September 30, 2021 and 2022, the Company recorded corresponding income tax benefits of $ 0.6 million and $ 0.3 million, respectively, and for the nine-month periods ended September 30, 2021 and 2022, the Company recorded corresponding tax benefits of $ 3.0 million and $ 0.8 million, respectively. As of September 30, 2022, the Company estimates the pre-tax unrecognized compensation expense of $ 25.0 million, net of estimated forfeitures, related to all unvested share-based awards, including share options and restricted share units will be recognized through the third quarter of 2026. The Company expects to satisfy the exercise of share options and future distributions of shares for restricted share units by issuing new ordinary shares that have been reserved under the 2019 Plan. The Company uses the Black-Scholes option pricing model to estimate the fair value of share options. The Company utilized a forfeiture rate of 8.2 % during the nine-month period ended September 30, 2022 for estimating the forfeitures of share options and restricted share units granted. Share options Share options typically have a contractual term of ten years from grant date and typically vest over a four-year period.

At September 30, 2022, there was $ 13.7 million in unrecognized pre-tax share-based compensation expense, net of estimated forfeitures, related to unvested share option awards. The unrecognized share-based compensation expense is expected to be recognized through the third quarter of 2026. The fair value of options granted are estimated on the date of grant using the Black-Scholes option pricing model. The fair value of share options is being amortized on a straight-line basis over the requisite service period of the awards. The fair value of share options is estimated using the following weighted-average assumptions (unaudited): Nine Months Ended September 30, 2021 2022 Expected dividend yield — — Risk-free interest rate 1.14 % 2.96 % Weighted-average expected volatility 50.9 % 72.9 % Expected term (in years) 6.5 5.5 Weighted average grant-date fair value per share of options granted $ 21.36 $ 9.94 Restricted shares Restricted shares typically vest over a four-year period.

As of September 30, 2022, there was $ 11.3 million in unrecognized pre-tax compensation expense, net of estimated forfeitures, related to unvested restricted share units. The unrecognized compensation expense is expected to be recognized through the third quarter of 2026. Employee share purchase plan In June 2019, the Company’s Board of Directors adopted, and its shareholders approved, the Employee Share Purchase Plan (“ESPP”). The ESPP was effective on June 25, 2019, and the initial offering period of six-months commenced on January 1, 2021. The current offering period of six months commenced on July 1, 2022 and runs through December 31, 2022. The purchase price of the shares is 85 % of the lower of the fair market value of the Company’s ordinary shares on the first trading day of the offering period and the purchase date. The ESPP includes an annual increase to the shares available for sale on the first day of each fiscal year beginning in 2020, equal to the lesser of: 275,000 shares, 1 % of the outstanding shares as of the last day of the immediately preceding fiscal year, or such other amount as the administrator may determine. The Company registered 267,352 additional shares on February 25, 2022. For the three-month periods ended September 30, 2021 and 2022, the Company recognized $ 0.2 million and $ 0.2 million, respectively, of share-based compensation expense related to the ESPP. For the nine-month periods ended September 30, 2021 and 2022, the Company recognized $ 0.5 million and $ 0.7 million, respectively, of share-based compensation expense related to the ESPP. There were 39,061 shares issued under the ESPP during the six-month offering period that ended on June 30, 2021 and 87,229 shares issued under the ESPP during the six-month offering period that ended on June 30, 2022.

Earnings Per Share [Abstract]
Earnings per share	Note 11. Earnings per share Basic net earnings per share is computed by dividing net income by the weighted-average number of shares outstanding during the period. Diluted net earnings per share is computed by giving effect to all potentially dilutive ordinary share equivalents outstanding for the period. For purposes of this calculation, share options, RSUs, RSAs, and ESPP awards are considered to be ordinary share equivalents but are excluded from the calculation of diluted earnings per share when including them would have an anti-dilutive effect.

Income Tax Disclosure [Abstract]
Income taxes	Note 12. Income taxes The Company’s provision for income taxes is based upon the estimated annual tax rate for the year applied to federal, state and foreign income. The Company recorded a provision for income taxes of $ 0.4 million and a benefit for income taxes of $ 0.2 million for the three-month periods ended September 30, 2021 and 2022, with an effective tax rate of 7.1 % and ( 1.7 )%, respectively. In the three-month period ended September 30, 2021, the effective tax rate of 7.1 % was different from the statutory rate of 21.0 %, primarily due to tax benefits arising on employee restricted share vesting and option exercises. For the three-month period ended September 30, 2022, the Company’s effective tax rate of ( 1.7 )% was different from the statutory rate of 21.0 %, primarily due to Foreign Derived Intangible Income, tax benefits arising on Research and Development tax credits, and changes to excess tax benefits on share-based compensation. In the nine-month periods ended September 30, 2021 and 2022, the Company recorded a tax benefit of $ 5.9 million and $ 1.0 million, respectively, with an effective income tax rate of ( 19.6 )% and ( 11.5 )%, respectively. For the nine-month period ended September 30, 2021 the effective income tax rate of ( 19.6 )% was different from the statutory rate of 21 %, primarily due to the release of a valuation allowance against the loss carryforwards in the Company’s UK entity and tax benefits arising on employee restricted share vesting and option exercises. For the nine-month period ended September 30, 2022, the effective income tax rate of ( 11.5 )% was different from the statutory rate of 21 %, primarily due to tax benefits arising on Research and Development tax credits, Foreign Derived Intangible Income, the revaluing of certain UK deferred tax assets at a higher future tax rate, and changes to excess tax benefits on share-based compensation. The Company reviews the likelihood that it will realize the benefit of its deferred tax assets and, therefore, the need for a valuation allowance on a quarterly basis. In the first quarter of 2021, management concluded that all of the valuation allowance on the Company’s UK entity’s deferred tax assets was no longer needed. This was primarily due to a 12-quarter cumulative income through the first quarter of 2021 and the forecast of future taxable income. Accordingly, management recognized in 2021 a non-recurring tax benefit of $ 7.7 million related to the valuation allowance reversal. As of September 30, 2022, the Company continues to believe it is more likely than not that the net deferred tax assets will be realized by its UK entity.

Commitments and Contingencies Disclosure [Abstract]
Commitments and contingencies	Note 13. Commitments and contingencies In accordance with ASC 460, Guarantees , the Company recognizes the fair value for guarantee and indemnification arrangements it issues or modifies, if these arrangements are within the scope of the interpretation. In addition, the Company must continue to monitor the conditions that are subject to the guarantees and indemnifications in order to identify if a loss has incurred. If the Company determines it is probable that a loss has occurred, then any such estimated loss would be recognized under those guarantees and indemnifications and would be recognized in the Company’s condensed consolidated statements of operations and corresponding condensed consolidated balance sheets during that period. Indemnification The Company generally indemnifies its customers against claims brought by a third party to the extent any such claim alleges that the Company’s product infringes a patent, copyright or trademark or violates any other proprietary rights of that third party. The maximum potential amount of future payments the Company may be required to make under these indemnification agreements is not estimable. The Company indemnifies its directors and officers and select key employees, including key employees serving as directors or officers of the Company’s subsidiaries, for certain events or occurrences, subject to certain limits, while the director or officer is or was serving at the Company’s request in such capacity. The term of the indemnification period is for the director’s or officer’s term of service. The Company may terminate the indemnification agreements with its directors, officers or key employees upon the termination of their services as directors or officers of the Company or its subsidiaries, or the termination of activities for which indemnification has been provided, but termination will not affect claims for indemnification related to events occurring prior to the effective date of termination. The maximum amount of potential future indemnification is unlimited; however, the Company has a director and officer insurance policy that limits its exposure. The Company believes the fair value of these indemnification agreements is minimal. Purchase commitments with contract manufacturers and suppliers We purchase components from a variety of suppliers and use contract manufacturers to provide manufacturing services for our products. During the normal course of business, in order to manage manufacturing lead times and help ensure adequate component supply, we enter into agreements with contract manufacturers and suppliers that allow them to procure inventory based upon criteria as defined by us, such as forecasted demand. The Company may be liable to purchase excess product or aged material from our suppliers following reasonable mitigation efforts. Warranties The Company offers a standard warranty on its products, with the term depending on the product, and records a liability for the estimated future costs associated with potential warranty claims. The Company’s responsibility under its standard warranty is the repair or replacement of in-warranty defective product, or to credit the purchase price of the defective product, at its discretion, without charge to the customer. The Company’s estimate of future warranty costs is largely based on historical experience factors including product failure rates, material usage, and service delivery cost incurred in correcting product failures. The standard warranty is included in either Other current liabilities or Other noncurrent liabilities on its condensed consolidated balance sheets, depending on the time period covered by the warranty. The Company also offers an extended warranty for purchase that represents a future performance obligation for the Company. The extended warranty is included in deferred revenues (both current and noncurrent) on the condensed consolidated balance sheets and recognized on a straight-line basis over the term of the extended warranty. The warranty costs are reflected in the Company’s condensed consolidated statements of operations within cost of revenues. Legal proceedings Third parties may from time to time assert legal claims against the Company. The Company records accruals for loss contingencies to the extent that it concludes it is probable that a liability has been incurred and the amount of the related loss can be reasonably estimated. The Company evaluates, on a regular basis, developments in legal proceedings and other matters that could cause a change in amounts recorded. Due to the inherent uncertainty involving legal matters, the ultimate resolution could differ from amounts recorded. There is no pending or threatened legal proceedings to which the Company is a party, that in the Company’s opinion, is likely to have a material adverse effect on its financial condition or results of operations.

Revenues from contracts with customers	Note 15. Revenues from contracts with customers Revenues consist primarily of revenues from the sale of hardware products with essential embedded software. Revenues also include limited amounts for software products, extended warranty on hardware products and subscription services. Substantially all products are sold through distributors and other channel partners, such as resellers and systems integrators. The Company recognizes revenue to reflect the transfer of control of promised products or services to a customer in an amount that reflects the consideration to which the Company expects to be entitled in exchange for products or services. The Company accounts for a contract when it has approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of consideration is probable. The Company identifies its distinct performance obligations under each contract. A performance obligation is a promise in a contract to transfer a distinct product or service to the customer. Hardware products with essential embedded software, software products, and purchased extended warranty on hardware products have been identified as separate and distinct performance obligations. The transaction price is the amount of consideration to which the Company expects to be entitled in exchange for transferring products or services to a customer. An adjustment to revenue is made to adjust the transaction price to exclude the consideration related to products expected to be returned. The Company records an asset at the carrying amount of the estimated stock returns and a liability for the estimated amount expected to be refunded to the customer. The transaction price also excludes other forms of consideration provided to the customer, such as volume-based rebates and co-operative marketing allowances. The Company recognizes revenue when, or as, it satisfies a performance obligation by transferring control of a promised product or service to a customer. Revenue from hardware products with essential embedded software is recognized when control of the asset is transferred, which is typically at the time of shipment. Revenue from perpetual license software is recognized at the point in time that the customer is able to use or benefit from the software. Extended warranty on hardware products is a performance obligation that is satisfied over time, beginning on the effective date of the warranty period and ending on the expiration of the warranty period. The Company recognizes revenue on extended warranties on a straight-line basis over the warranty period. Revenue from software subscriptions is recognized ratably over the term in which the services are provided and the performance obligation is satisfied. The Company enters into revenue arrangements that may consist of multiple performance obligations, such as hardware products and extended warranty. The Company allocates the transaction price to each performance obligation on a relative standalone selling price basis for each distinct product or service in the contract. The best evidence of standalone selling price is the observable price of a product or service when the Company sells that product or service separately in similar circumstances and to similar customers. If a standalone selling price is not directly observable, the Company estimates the transaction price allocated to each performance obligation using the expected costs plus a margin approach. Disaggregation of revenues Revenues by product category were as follows (unaudited and in thousands, except percentages): Three Months Ended September 30, Nine Months Ended September 30, 2021 2022 2021 2022 Point-to-Multi-Point $ 50,144 66 % $ 26,090 32 % $ 167,739 65 % $ 85,285 40 % Point-to-Point 13,890 18 % 15,409 19 % 45,432 18 % 45,807 21 % Enterprise 10,734 14 % 38,330 47 % 41,154 16 % 77,852 37 % Other 1,152 2 % 1,371 2 % 2,819 1 % 3,448 2 % Total Revenues $ 75,920 100 % $ 81,200 100 % $ 257,144 100 % $ 212,392 100 % In the above table, the Company has renamed the Wi-Fi product category to Enterprise to more accurately represent the products and services included in this product category, which includes Wi-Fi, switching and software subscriptions. The Company’s products are predominately sold through third-party distributors, and distributed through a third-party logistics provider with facilities in the United States, Netherlands and China. The Company has determined the geographical distribution of product revenues based upon the ship-to destinations specified by its distributor customers. Revenues by geography were as follows (unaudited and in thousands, except percentages): Three Months Ended September 30, Nine Months Ended September 30, 2021 2022 2021 2022 North America $ 36,564 48 % $ 30,086 37 % $ 140,105 54 % $ 89,547 42 % Europe, Middle East and Africa 23,414 31 % 29,263 36 % 67,047 26 % 70,876 34 % Caribbean and Latin America 7,993 11 % 8,935 11 % 30,660 12 % 21,979 10 % Asia Pacific 7,949 10 % 12,916 16 % 19,332 8 % 29,990 14 % Total Revenues $ 75,920 100 % $ 81,200 100 % $ 257,144 100 % $ 212,392 100 % Contract balances The following table summarizes contract balances as of December 31, 2021 and September 30, 2022 (in thousands): December 31, September 30, (unaudited) Trade accounts receivable, net of allowance for $ 68,788 $ 83,679 Deferred revenue - current 6,880 8,226 Deferred revenue - noncurrent 5,363 8,201 Refund liability $ 2,516 $ 3,051 Deferred revenue consists of amounts due or received from customers in advance of the Company satisfying performance obligations under contractual arrangements. Deferred revenue is classified as current or noncurrent based on the timing of when revenue will be recognized. The changes in deferred revenue were due to normal timing differences between the Company’s performance and the customers’ payment. The refund liability is the estimated amount expected to be refunded to customers in relation to product exchanges made as part of the Company’s stock rotation program and returns that have been authorized, but not yet received by the Company. It is included within Other current liabilities in the condensed consolidated balance sheets. Receivables and concentration of credit risk Trade accounts receivable represents amounts for which the Company has an unconditional right to payment. Amounts are in accordance with contractual terms and are recorded at face amount less an allowance for credit losses. The Company establishes an allowance for credit losses to present the net amount of accounts receivable expected to be collected. The allowance is determined by using the loss-rate method, which requires an estimation of loss rates based upon historical loss experience adjusted for factors that are relevant to determining the expected collectability of accounts receivables. Some of these factors include macroeconomic conditions that correlate with historical loss experience, delinquency trends, aging behavior of receivables and credit and liquidity indicators for individual customers. The Company considers the credit risk of all customers and regularly monitors credit risk exposure in its trade receivables. The Company’s standard credit terms with its customers are generally net 30 to 60 days . The Company had one customer representing more than 10 % of trade receivables at December 31, 2021 and one customer representing more than 10 % of trade receivables at September 30, 2022. Remaining performance obligations Remaining performance obligations represent the revenue that is expected to be recognized in future periods related to performance obligations included in a contract that are unsatisfied, or partially satisfied, as of the end of a period. As of December 31, 2021, deferred revenue (current and noncurrent) of $ 12.2 million represents the Company’s remaining performance obligations, of which $ 6.9 million is expected to be recognized within one year , with the remainder to be recognized thereafter. As of September 30, 2022, deferred revenue (current and noncurrent) of $ 16.4 million represents the Company’s remaining performance obligations, of which $ 8.2 million is expected to be recognized within one year , with the remainder to be recognized thereafter (unaudited). Revenue recognized during the three-month and nine-month periods ended September 30, 2022 which was previously included in deferred revenues as of December 31, 2021 was $ 1.5 million and $ 5.7 million, respectively, compared to $ 1.8 million and $ 5.4 million of revenue recognized during the three-month and nine-month periods ended September 30, 2021, respectively, which was previously included in deferred revenues as of December 31, 2020 (unaudited). Cost to obtain a contract Sales commissions are incremental costs of obtaining a contract. The Company has elected to recognize these expenses as incurred, as the amortization period of these costs is one year or less.
