INTERIM FINANCIAL STATEMENTS	Apr. 30, 2022
Quarterly Financial Data [Abstract]
INTERIM FINANCIAL STATEMENTS	INTERIM FINANCIAL STATEMENTS The interim financial statements included herein for Ciena Corporation and its wholly owned subsidiaries (“Ciena”) have been prepared by Ciena, without audit, pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”). The preparation of financial statements and related disclosures in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires Ciena to make judgments, assumptions, and estimates that affect the amounts reported in the Condensed Consolidated Financial Statements and accompanying notes. The inputs into certain of Ciena’s judgments, assumptions, and estimates reflect, among other things, the information available to Ciena regarding the economic implications of the COVID-19 pandemic, and expectations as to its impact on Ciena’s business. Among other things, these estimates form the basis for judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ materially from these estimates under different assumptions or conditions. To the extent that there are material differences between Ciena’s estimates and actual results, Ciena’s consolidated financial statements will be affected. In addition, because the duration and severity of COVID-19 pandemic are uncertain, certain of these estimates could require further judgment or modification and therefore carry a higher degree of variability and volatility. As events continue to evolve, Ciena’s estimates may change materially in future periods. In the opinion of management, the financial statements included in this report reflect all normal recurring adjustments that Ciena considers necessary for the fair statement of the results of operations of Ciena for the interim periods covered and of the financial position of Ciena at the date of the interim balance sheets. Certain information and footnote disclosures normally included in the annual financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to SEC rules and regulations. The Condensed Consolidated Balance Sheet as of October 30, 2021 was derived from audited financial statements, but does not include all disclosures required by GAAP. However, Ciena believes that the disclosures are adequate to understand the information presented herein. The operating results for interim periods are not necessarily indicative of the operating results for the entire year. These financial statements should be read in conjunction with Ciena’s audited consolidated financial statements and the notes thereto included in Ciena’s annual report on Form 10-K for fiscal 2021 (the “2021 Annual Report”). Ciena has a 52 or 53-week fiscal year, with quarters ending on the Saturday nearest to the last day of January, April, July and October, respectively, of each year. Fiscal 2022 and 2021 are 52-week fiscal years.

Accounting Policies [Abstract]
SIGNIFICANT ACCOUNTING POLICIES	SIGNIFICANT ACCOUNTING POLICIES Except for the changes in certain policies described below, there have been no material changes to Ciena’s significant accounting policies, compared to the accounting policies described in Note 1, Ciena Corporation and Significant Accounting Policies and Estimates, in Notes to Consolidated Financial Statements in Item 8 of Part II of the 2021 Annual Report. Newly Issued Accounting Standards - Effective In December 2019, the Financial Accounting Standards Board (the ”FASB”) issued Accounting Standards Update No. 2019-12 (“ASU 2019-12”), Income Taxes (ASC 740): Simplifying the Accounting for Income Taxes, which simplifies the accounting for income taxes by removing certain exceptions to the general principles in ASC 740. The amendments also improve consistent application of and simplify GAAP for other areas of ASC 740 by clarifying and amending existing guidance. Most amendments within this standard are required to be applied on a prospective basis, while certain amendments must be applied on a retrospective or modified retrospective basis. ASU 2019-12 was effective for Ciena beginning in the first quarter of fiscal 2022. Ciena adopted ASU 2019-12 beginning in the first quarter of fiscal 2022 without any material impact on its financial position and results of operations. In November 2021, the FASB issued ASU No. 2021-10 (“ASU 2021-10”), Government Assistance, to increase transparency of government assistance including the disclosure of (1) the types of assistance, (2) an entity’s accounting for the assistance, and (3) the effect of the assistance on an entity’s financial statements. ASU 2021-10 was effective for annual periods beginning after December 15, 2021. Early adoption was permitted. Ciena adopted ASU 2021-10 in the first quarter of fiscal 2022 without any material impact on its financial position and results of operations In March 2020, the FASB issued ASU No. 2020-04 (“ASU 2020-04”), Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. ASU 2020-04 provides temporary optional guidance on contract modifications and hedging accounting to ease the financial reporting burdens of the expected market transition from the London Interbank Offered Rate (“LIBOR”) to alternative reference rates. In January 2021, the FASB issued ASU No. 2021-01, which refines the scope of Topic 848 and clarifies some of its guidance as part of the FASB’s monitoring of global reference rate activities. The new guidance was effective upon issuance and may be applied prospectively through December 31, 2022. Ciena adopted Topic 848 beginning in the first quarter of fiscal 2022 without any material impact on its financial position and results of operations. Newly Issued Accounting Standards - Not Yet Effective In October 2021, the FASB issued ASU No. 2021-08 (“ASU 2021-08”), Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers to improve the accounting for acquired revenue contracts with customers in a business combination to address recognition of an acquired contract liability and payment terms and their effect on subsequent revenue recognized by the acquirer. ASU 2021-08 is effective for annual periods beginning after December 15, 2022 on a prospective basis. Early adoption is permitted. Ciena is currently evaluating the impact of this ASU on its condensed consolidated financial statements and related disclosures.

Contract Balances

The following table provides information about receivables, contract assets and contract liabilities (deferred revenue) from contracts with customers (in thousands):


	Balance at April 30, 2022		Balance at October 30, 2021
Accounts receivable, net	$	774,896	$	884,958
Contract assets for unbilled accounts receivable, net	$	144,344	$	101,355
Deferred revenue	$	218,769	$	175,464

Ciena’s contract assets represent unbilled accounts receivable, net where transfer of a product or service has occurred but invoicing is conditional upon completion of future performance obligations. These amounts are primarily related to installation and deployment and professional services arrangements where transfer of control has occurred, but Ciena has not yet invoiced the customer. Contract assets are included in prepaid expenses and other in the Condensed Consolidated Balance Sheets. See Note 12 below.

Contract liabilities consist of deferred revenue and represent advanced payments against non-cancelable customer orders received prior to revenue recognition. Ciena recognized approximately $82.0 million and $78.0 million of revenue during the first six months of fiscal 2022 and 2021, respectively, that was included in the deferred revenue balance as of October 30, 2021 and October 31, 2020, respectively. Revenue recognized due to changes in transaction price from performance obligations satisfied or partially satisfied in previous periods was immaterial during the six months ended April 30, 2022 and May 1, 2021.

Capitalized Contract Acquisition Costs

Capitalized contract acquisition costs consist of deferred sales commissions, and were $32.5 million and $27.6 million as of April 30, 2022 and October 30, 2021, respectively. Capitalized contract acquisition costs were included in (i) prepaid expenses and other and (ii) other long-term assets.

Business Combination and Asset Acquisition [Abstract]

BUSINESS COMBINATIONS

Vyatta and Xelic Acquisitions

On November 1, 2021, Ciena acquired AT&T’s Vyatta Software Technology (“Vyatta”), a provider of software-based virtual routing and switching technology. AT&T is a customer of Ciena, see Note 3 above. On March 9, 2022, Ciena acquired Xelic, Inc. (“Xelic”), a provider and developer of field programmable gate array (FPGA) and application-specific integrated circuit (ASIC) technology and optical networking IP cores. These businesses were acquired for an aggregate of approximately $64.3 million, of which $63.5 million was paid in cash and $0.8 million represents a future payable arrangement. These transactions have each been accounted for as the acquisition of a business.

Ciena incurred approximately $1.7 million in acquisition-related costs associated with these acquisitions. These costs and expenses primarily include fees associated with financial, legal and accounting advisors. These costs were recorded in acquisition and integration costs in the Condensed Consolidated Statement of Operations.

The following table summarizes the final purchase price allocation related to the acquisitions based on the estimated fair value of the acquired assets and assumed liabilities (in thousands):


	Amount
Cash and cash equivalents	$	201
Prepaid expenses and other	1,614
Equipment, furniture and fixtures	694
Customer relationships and contracts	15,800
Developed technology	32,491
Goodwill	17,982
Accrued liabilities	(4,434)
Total purchase consideration	$	64,348

Customer relationships and contracts represent agreements with existing Vyatta customers and have an estimated useful life of two years.

Developed technology represents purchased technology that has reached technological feasibility and for which the acquired companies had substantially completed development as of the date of acquisition. Fair value was determined using future discounted cash flows related to the projected income stream of the developed technology for a discrete projection period. Cash flows were discounted to their present value as of the closing date. Developed technology is amortized on a straight-line basis over its estimated useful life of five years.

The goodwill generated from these acquisitions are primarily related to expected economic synergies. The total goodwill amount was recorded in the Networking Platforms segment. The goodwill is not deductible for income tax purposes.

Pro forma disclosures have not been included due to immateriality. The amounts of revenue and earnings for these acquisitions since the acquisition dates, which are included in the Condensed Consolidated Statement of Operations for the reporting period are immaterial.

CANADIAN EMERGENCY WAGE SUBSIDY

6 Months Ended

Apr. 30, 2022

Unusual or Infrequent Items, or Both [Abstract]

CANADIAN EMERGENCY WAGE SUBSIDY

In April 2020, the Canadian government introduced the Canada Emergency Wage Subsidy (“CEWS”) to help employers offset a portion of their employee wages for a limited period in response to the COVID-19 outbreak, retroactive to March 15, 2020. The CEWS program expired in October 2021. The subsidy covered employers of all sizes and across all sectors.

Ciena accounts for proceeds from government grants as a reduction of expense when there is reasonable assurance that Ciena has met the required conditions associated with the grant and that grant proceeds will be received. Grant benefits are recorded to the particular line item of the Condensed Consolidated Statement of Operations to which the grant activity relates. During the second quarter and six months ended May 1, 2021, Ciena recorded a CAD$51.1 million ($40.4 million) benefit, net of certain fees, related to CEWS for claim periods beginning March 15, 2020, including CAD$43.9 million ($34.7 million) related to employee wages during fiscal 2020.

The following table summarizes CEWS for the periods indicated (in thousands, USD):

SIGNIFICANT ASSET IMPAIRMENT AND RESTRUCTURING COSTS

Restructuring Costs

Ciena has undertaken a number of restructuring activities intended to reduce expense and to align its workforce and costs with market opportunities, product development and business strategies. The following table sets forth the restructuring activity and balance of the restructuring liability accounts, which are included in accrued liabilities and other short-term obligations on the Condensed Consolidated Balance Sheets, for the six months ended April 30, 2022 (in thousands):

Balance at October 30, 2021	$	781		$	—		$	781
Charges	1,413		(1)	7,018		(2)	8,431

Cash payments	(1,388)			(7,018)			(8,406)
Balance at April 30, 2022	$	806		$	—		$	806
Current restructuring liabilities	$	806		$	—		$	806

(1) Reflects employee costs associated with workforce reductions during the six months ended April 30, 2022 as part of a business optimization strategy to improve gross margin, constrain operating expense and redesign certain business processes.

(2) Primarily represents the redesign of certain business processes associated with Ciena’s supply chain and distribution structure reorganization and costs related to restructured real estate facilities.

The following table sets forth the restructuring activity and balance of the restructuring liability accounts, which are included in accrued liabilities and other short-term obligations on the Condensed Consolidated Balance Sheets for the six months ended May 1, 2021 (in thousands):

Significant Asset Impairments

In February 2022, armed conflict escalated between Russia and Ukraine. The United States and certain other countries have imposed sanctions on Russia and could impose further sanctions. On March 7, 2022, Ciena announced its decision to immediately suspend its business operations in Russia. As a result, Ciena recorded impairment charges of $4.1 million of which $2.0 million was a provision for credit losses.

Interest and other income (loss), net	$	808	$	(1,274)	$	4,494	$	(2,395)

Ciena Corporation, as the U.S. parent entity, uses the U.S. Dollar as its functional currency; however, some of its foreign branch offices and subsidiaries use local currencies as their functional currencies. Ciena recorded $3.5 million in foreign currency exchange rate gains for the first six months of fiscal 2022 and during the first six months of fiscal 2021, Ciena recorded $13.5 million in foreign currency exchange rate losses, both as a result of monetary assets and liabilities that were transacted in a currency other than Ciena’s functional currency. The related remeasurement adjustments were recorded in interest and other income (loss), net, on the Condensed Consolidated Statements of Operations. From time to time, Ciena uses foreign currency forwards to hedge this type of balance sheet exposure. These forwards are not designated as hedges for accounting purposes, and any net gain or loss associated with these derivatives is reported in interest and other income (loss), net, on the Condensed Consolidated Statements of Operations. During the first six months of fiscal 2022, Ciena recorded losses of $1.9 million and during the first six months of fiscal 2021, Ciena recorded gains of $9.7 million from non-hedge designated foreign currency forward contracts. During the first six months of fiscal 2022, Ciena recorded an unrealized gain of $4.1 million on its cost method equity investment.

INCOME TAXES	6 Months Ended
INCOME TAXES	Apr. 30, 2022
Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES The effective tax rate for the quarter ended April 30, 2022 was higher than the effective tax rate for the quarter ended May 1, 2021, primarily due to a higher foreign tax rate. The effective tax rate for the six months ended April 30, 2022 was lower than the effective tax rate for the six months ended May 1, 2021, primarily due to a lower foreign tax rate in the six months ended April 30, 2022. Ciena’s future income tax provisions and deferred tax balances may be affected by the amount of pre-tax income, the jurisdictions where it is earned, the existence and ability to utilize tax attributes and changes in tax laws and business reorganizations. Ciena continues to monitor these items and will adopt strategies to address their impact as appropriate. In certain jurisdictions, Ciena provides a valuation allowance for its deferred tax assets in excess of deferred tax liabilities because Ciena has concluded that it is more likely than not that such deferred tax assets will ultimately not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income (including the reversals of deferred tax liabilities) during the periods in which those deferred tax assets will become deductible. Ciena assesses available positive and negative evidence regarding its ability to realize deferred tax assets and record a valuation allowance when it is more likely than not that deferred tax assets will not be realized. To form a conclusion, management considers its recent financial results and trends and makes judgments and estimates related to projections of profitability, the timing and extent of the use of net operating loss carryforwards, and tax planning strategies. Ciena will continue to evaluate future financial performance to determine whether such profitability is both sustainable and significant enough to provide sufficient evidence to support reversal of all or a portion of the valuation allowance. Any future release of valuation allowance may be recorded as a tax benefit increasing net income or as an adjustment to paid-in capital, based on tax ordering requirements.

- Definition

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.

Inventory Disclosure [Abstract]

INVENTORIES

As of the dates indicated, inventories are comprised of the following (in thousands):


	April 30, 2022		October 30, 2021
Raw materials	$	373,517	$	175,399
Work-in-process	12,268		10,260

Reserve for inventory excess and obsolescence	(35,747)		(36,959)
Inventories, net	$	536,878	$	374,265

The increase in raw materials inventory is related to the steps Ciena is taking to mitigate the impact of current supply chain constraints and the global market shortage of semiconductor parts. Ciena writes down its inventory for estimated obsolescence or unmarketable inventory by an amount equal to the difference between the cost of inventory and the estimated net realizable value based on assumptions about future demand, which are affected by changes in Ciena’s strategic direction, discontinuance of a product or introduction of newer versions of products, declines in the sales of or forecasted demand for certain products, and general market conditions. During the first six months of fiscal 2022, Ciena recorded a provision for inventory excess and obsolescence of $8.5 million, primarily related to a decrease in the forecasted demand for certain Networking Platforms products. Deductions from the provision for excess and obsolete inventory relate primarily to disposal activities.

DERIVATIVE INSTRUMENTS	6 Months Ended
DERIVATIVE INSTRUMENTS	Apr. 30, 2022
Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVE INSTRUMENTS	DERIVATIVE INSTRUMENTS Foreign Currency Derivatives Ciena conducts business globally in numerous currencies, and thus is exposed to adverse foreign currency exchange rate changes. To limit this exposure, Ciena enters into foreign currency contracts. Ciena does not enter into such contracts for speculative purposes. As of April 30, 2022 and October 30, 2021, Ciena had forward contracts to hedge its foreign exchange exposure in order to reduce variability that is principally related to research and development activities. The notional amount of these contracts was approximately $251.5 million and $288.6 million as of April 30, 2022 and October 30, 2021, respectively. These foreign exchange contracts have maturities of 24 months or less and have been designated as cash flow hedges. As of April 30, 2022 and October 30, 2021, Ciena had forward contracts to hedge its foreign exchange exposure in order to reduce the variability in various currencies of certain balance sheet items. The notional amount of these contracts was approximately $93.1 million and $296.1 million as of April 30, 2022 and October 30, 2021, respectively. These foreign exchange contracts have maturities of 12 months or less and have not been designated as hedges for accounting purposes. Interest Rate Derivatives Ciena is exposed to floating rates of LIBOR interest on its term loan borrowings (see Note 16 below) and has hedged such risk by entering into floating to fixed interest rate swap arrangements (“interest rate swaps”). The interest rate swaps fix the LIBOR rate for $350.0 million of the 2025 Term Loan (as defined in Note 16 below) at 2.957% through September 2023. The total notional amount of interest rate swaps in effect was $350.0 million as of April 30, 2022 and October 30, 2021. In April 2022, Ciena entered into floating to fixed forward starting interest rate swap arrangements (“forward starting swaps”). The forward starting swaps fix the Secured Overnight Funding Rate (“SOFR”) for $350.0 million of the 2025 Term Loan (as defined in Note 16 below) at 2.968% from September 2023 through the 2025 Term Loan maturity. The total notional amount of forward starting swaps effective September 2023 was $350 million as of April 30, 2022. Ciena entered into the forward starting swaps to hedge its anticipated SOFR rate risk from the 2025 Term Loan because the LIBOR rate is expected to be discontinued in 2023. Ciena expects the variable rate payments to be received under the terms of the interest rate swaps and forward starting swaps to offset exactly the forecasted variable rate payments on the equivalent notional amounts of the 2025 Term Loan. These derivative contracts have been designated as cash flow hedges. Other information regarding Ciena’s derivatives is immaterial for separate financial statement presentation. See Note 7 and Note 10 above.

SHORT-TERM AND LONG-TERM DEBT

Debt Disclosure [Abstract]

SHORT-TERM AND LONG-TERM DEBT

2025 Term Loan

On January 23, 2020, Ciena entered into a Refinancing Amendment to Credit Agreement pursuant to which Ciena refinanced the entire outstanding amount of its then existing senior secured term loan and incurred a new senior secured term loan in an aggregate principal amount of $693.0 million and maturing on September 28, 2025 (the “2025 Term Loan”).

The net carrying value of the 2025 Term Loan was comprised of the following for the periods indicated (in thousands):


	April 30, 2022								October 30, 2021
	Principal Balance		Unamortized Discount		Deferred Debt Issuance Costs		Net Carrying Value		Net Carrying Value
2025 Term Loan	$	677,407	$	(1,089)	$	(2,037)	$	674,281	$	677,285

Deferred debt issuance costs that were deducted from the carrying amounts of the 2025 Term Loan totaled $2.0 million as of April 30, 2022 and $2.3 million at October 30, 2021. Deferred debt issuance costs are amortized using the straight-line method, which approximates the effect of the effective interest rate, through the maturity of the 2025 Term Loan. The amortization of deferred debt issuance costs for the 2025 Term Loan is included in interest expense, and was $0.3 million during the first six months of each of fiscal 2022 and fiscal 2021. The carrying value of the 2025 Term Loan listed above is also net of any unamortized debt discounts.

As of April 30, 2022, the estimated fair value of the 2025 Term Loan was $677.5 million. Ciena’s 2025 Term Loan is categorized as Level 2 in the fair value hierarchy. Ciena estimated the fair value of its 2025 Term Loan using a market approach based on observable inputs, such as current market transactions involving comparable securities.

2030 Notes

On January 18, 2022, Ciena entered into an Indenture among Ciena, as issuer, certain domestic subsidiaries of Ciena, as guarantors (collectively, the “Guarantors”), and U.S. Bank National Association, as trustee (the “Trustee”), pursuant to which Ciena issued $400.0 million in aggregate principal amount of 4.00% senior notes due 2030 (the “2030 Notes”).

Ciena’s obligations under the 2030 Notes and the Indenture are irrevocably and unconditionally guaranteed, jointly and severally, on an unsecured senior basis by each of its domestic subsidiaries that is a borrower under or guarantor with respect to the 2025 Term Loan and Ciena’s senior secured asset-based revolving credit facility (the “ABL Credit Facility”).

The net proceeds from the sale of the 2030 Notes, after deducting costs, were approximately $395.5 million. Ciena intends to use the net proceeds from the Offering for general corporate purposes.

The 2030 Notes bear interest at a rate of 4.00% per annum and mature on January 31, 2030. Interest is payable on the 2030 Notes in arrears on January 31 and July 31 of each year, commencing on July 31, 2022.

The 2030 Notes and related subsidiary guarantees are the general unsubordinated unsecured senior obligations of Ciena and the Guarantors, respectively, and (i) rank equally in right of payment with all other existing and future senior indebtedness of Ciena and the Guarantors; (ii) are effectively subordinated to all existing and future secured indebtedness of Ciena and the Guarantors, including indebtedness under the 2025 Term Loan and the ABL Credit Facility, to the extent of the value of the assets securing such indebtedness; (iii) are structurally subordinated to all existing and future obligations, including indebtedness, of Ciena’s subsidiaries that do not guarantee the 2030 Notes; and (iv) are senior in right of payment to all of Ciena’s existing and future unsecured indebtedness that is, by its terms, expressly subordinated in right of payment to the 2030 Notes.

The Indenture contains restrictive covenants that limit the ability of Ciena and the Restricted Subsidiaries (as defined in the Indenture) or the Guarantors, as applicable, to, among other things, create certain liens or consolidate or merge with or into, or sell, lease, transfer, convey or otherwise dispose of all or substantially all the assets of Ciena or Ciena and its subsidiaries taken as a whole. These covenants are subject to a number of important exceptions and qualifications as set forth in the Indenture.

The Indenture provides for events of default (subject in certain cases to customary grace and cure periods) that include, among others, nonpayment of principal or interest when due, breach of covenants or other agreements in the Indenture, defaults in payment of certain other indebtedness and certain events of bankruptcy or insolvency. Generally, if an event of default occurs, the Trustee or the holders of at least 25% in principal amount of the outstanding 2030 Notes may declare the principal amount of and accrued but unpaid interest on all of the 2030 Notes to be due and payable immediately, provided that such amounts become due and payable without any further action or notice in the case of an event of bankruptcy or insolvency that constitutes an event of default.

Prior to January 31, 2025, Ciena may redeem the 2030 Notes, in whole or part, at a price equal to 100% of the principal amount thereof, plus a “make-whole” of 102% of the principal amount of the notes to be redeemed, and any accrued and unpaid interest. On or after January 31, 2025, Ciena may redeem the 2030 Notes, in whole or part, at the redemption prices set forth in the Indenture and form of the 2030 Notes, plus any accrued and unpaid interest. In addition, until January 31, 2025, Ciena may redeem up to 40% of the aggregate principal amount of the 2030 Notes with the net cash proceeds of certain equity offerings, as

described in the Indenture, at a redemption price equal to 104% of the principal amount of the 2030 Notes to be redeemed, plus any accrued and unpaid interest. If a change of control triggering event occurs, as described in the Indenture, Ciena must offer to repurchase all of the 2030 Notes (unless otherwise redeemed) at a price equal to 101% of the principal amount thereof, plus any accrued and unpaid interest.

The net carrying value of the 2030 Notes was comprised of the following for the period indicated (in thousands):


	April 30, 2022
	Principal Balance		Deferred Debt Issuance Costs		Net Carrying Value
2030 Senior Notes 4.00% fixed-rate	$	400,000	$	(5,169)	$	394,831

Deferred debt issuance costs that were deducted from the carrying amount of the 2030 Notes totaled $5.2 million as of April 30, 2022. Deferred debt issuance costs are amortized using the straight-line method, which approximates the effect of the effective interest rate, through the maturity of the 2030 Notes. The amortization of deferred debt issuance costs for the 2030 Notes is included in interest expense, and was $0.2 million during the first six months of fiscal 2022.

As of April 30, 2022, the estimated fair value of the 2030 Notes was $363.0 million. The 2030 Notes are categorized as Level 2 in the fair value hierarchy. Ciena estimated the fair value of its 2030 Notes using a market approach based on observable inputs, such as current market transactions involving comparable securities.

Earnings Per Share [Abstract]

EARNINGS PER SHARE CALCULATION

EARNINGS PER SHARE CALCULATIONBasic net income per common share (“Basic EPS”) is computed using the weighted average number of common shares outstanding. Diluted net income per potential common share (“Diluted EPS”) is computed using the weighted average number

of the following, in each case, to the extent that the effect is not anti-dilutive: (i) common shares outstanding; (ii) shares issuable upon vesting of stock unit awards; and (iii) shares issuable under Ciena’s employee stock purchase plan and upon exercise of outstanding stock options, using the treasury stock method.

Equity [Abstract]
STOCKHOLDERS’ EQUITY	STOCKHOLDERS’ EQUITY Stock Repurchase Program and Accelerated Share Repurchase Agreement On December 9, 2021, Ciena announced that its Board of Directors authorized a program to repurchase up to $1.0 billion of its common stock. On December 13, 2021, Ciena entered into an accelerated share repurchase agreement (the “ASR Agreement”) with Goldman, Sachs & Co. LLC (“Goldman”) to repurchase $250.0 million (the “Repurchase Price”) of its common stock as part of the repurchase program. Under the terms of the ASR Agreement, Ciena paid the Repurchase Price to Goldman, and received approximately 3.6 million shares of its common stock from Goldman, calculated based on the average of the volume-weighted average prices of Ciena’s common stock of $69.78 for the period from December 14, 2021 to February 11, 2022, less a discount, which completed the repurchases contemplated by the ASR Agreement. Shares repurchased pursuant to the ASR Agreement were immediately retired upon receipt. During the second quarter of fiscal 2022, Ciena repurchased an additional 1.5 million shares of its common stock, for an aggregate purchase price of $87.0 million at an average price of $57.92 per share. As of April 30, 2022, Ciena has repurchased an aggregate of 5.1 million shares for an aggregate purchase price of $337.0 million at an average price of $66.28 per share and has an aggregate of $663.0 million of authorized funds remaining under its stock repurchase program. The purchase price for the shares of Ciena’s stock repurchased is reflected as a reduction of common stock and additional paid-in capital. Stock Repurchases Related to Stock Unit Award Tax Withholdings Ciena repurchases shares of its common stock to satisfy employee tax withholding obligations due on vesting of stock unit awards. The related purchase price of $35.0 million for the shares of Ciena’s stock repurchased during the first six months of fiscal 2022 is reflected as a reduction to stockholders’ equity. Ciena is required to allocate the purchase price of the repurchased shares as a reduction of common stock and additional paid-in capital.

- Definition

The entire disclosure for shareholders' equity comprised of portions attributable to the parent entity and noncontrolling interest, including other comprehensive income. Includes, but is not limited to, balances of common stock, preferred stock, additional paid-in capital, other capital and retained earnings, accumulated balance for each classification of other comprehensive income and amount of comprehensive income.

Under these agreements, Ciena could have received up to an aggregate CAD$57.6 million (approximately $44.8 million) in reimbursement from the three Canadian government entities for eligible costs over the period from February 20, 2017 through March 31, 2022. Amounts received under the agreements were subject to recoupment in the event that Ciena fails to achieve certain minimum investment, employment and project milestones. Ciena accounts for proceeds from government grants as a reduction of expense when there is reasonable assurance that Ciena has met the required conditions associated with the grant and that grant proceeds will be received. Grant benefits are recorded to the particular line item of the Condensed Consolidated Statement of Operations to which the grant activity relates. As of April 30, 2022, Ciena has recorded CAD$57.6 million (approximately $44.8 million) in cumulative benefits as a reduction in research and development expense of which CAD$6.6 million ($5.2 million) was recorded in the first six months of fiscal 2022. As of April 30, 2022, amounts receivable from this grant were CAD$3.3 million ($2.6 million) included in prepaid expenses and other in the Condensed Consolidated Balance Sheets.

Ciena is also subject to intellectual property related claims, including claims against third parties that may involve contractual indemnification obligations on the part of Ciena.

SIGNIFICANT ACCOUNTING POLICIES (Policies)	Apr. 30, 2022
Accounting Policies [Abstract]
Newly Issued Accounting Standards - Effective and Not Yet Effective	Newly Issued Accounting Standards - Effective In December 2019, the Financial Accounting Standards Board (the ”FASB”) issued Accounting Standards Update No. 2019-12 (“ASU 2019-12”), Income Taxes (ASC 740): Simplifying the Accounting for Income Taxes, which simplifies the accounting for income taxes by removing certain exceptions to the general principles in ASC 740. The amendments also improve consistent application of and simplify GAAP for other areas of ASC 740 by clarifying and amending existing guidance. Most amendments within this standard are required to be applied on a prospective basis, while certain amendments must be applied on a retrospective or modified retrospective basis. ASU 2019-12 was effective for Ciena beginning in the first quarter of fiscal 2022. Ciena adopted ASU 2019-12 beginning in the first quarter of fiscal 2022 without any material impact on its financial position and results of operations. In November 2021, the FASB issued ASU No. 2021-10 (“ASU 2021-10”), Government Assistance, to increase transparency of government assistance including the disclosure of (1) the types of assistance, (2) an entity’s accounting for the assistance, and (3) the effect of the assistance on an entity’s financial statements. ASU 2021-10 was effective for annual periods beginning after December 15, 2021. Early adoption was permitted. Ciena adopted ASU 2021-10 in the first quarter of fiscal 2022 without any material impact on its financial position and results of operations In March 2020, the FASB issued ASU No. 2020-04 (“ASU 2020-04”), Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. ASU 2020-04 provides temporary optional guidance on contract modifications and hedging accounting to ease the financial reporting burdens of the expected market transition from the London Interbank Offered Rate (“LIBOR”) to alternative reference rates. In January 2021, the FASB issued ASU No. 2021-01, which refines the scope of Topic 848 and clarifies some of its guidance as part of the FASB’s monitoring of global reference rate activities. The new guidance was effective upon issuance and may be applied prospectively through December 31, 2022. Ciena adopted Topic 848 beginning in the first quarter of fiscal 2022 without any material impact on its financial position and results of operations. Newly Issued Accounting Standards - Not Yet Effective In October 2021, the FASB issued ASU No. 2021-08 (“ASU 2021-08”), Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers to improve the accounting for acquired revenue contracts with customers in a business combination to address recognition of an acquired contract liability and payment terms and their effect on subsequent revenue recognized by the acquirer. ASU 2021-08 is effective for annual periods beginning after December 15, 2022 on a prospective basis. Early adoption is permitted. Ciena is currently evaluating the impact of this ASU on its condensed consolidated financial statements and related disclosures.
