NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(unaudited)

(1)  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”). 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 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 accounting principles generally accepted in the United States of America (“GAAP”) have been condensed or omitted pursuant to such rules and regulations. The Condensed Consolidated Balance Sheet as of October 31, 2018 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 the fiscal year ended October 31, 2018.

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 2019 is a 52-week fiscal year. Fiscal 2018 was a 53-week fiscal year with the additional week occurring in the fourth quarter. For purposes of financial statement presentation, each fiscal year is described as having ended on October 31, and the fiscal quarters are described as having ended on January 31, April 30 and July 31 of each fiscal year.

(2) 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 Ciena’s annual report on Form 10-K for the fiscal year ended October 31, 2018.

Newly Issued Accounting Standards - Effective

Revenue Recognition

In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Codification (“ASC”) 606, Revenue from Contracts with Customers, a new accounting standard related to revenue recognition. ASC 606 supersedes nearly all U.S. GAAP standards on revenue recognition and eliminates industry-specific guidance. The underlying principle of ASC 606 is to recognize revenue when a customer obtains control of the promised products or services at an amount that reflects the consideration that is expected to be received in exchange for those products or services. ASC 606 also requires additional disclosures regarding the nature, amount, timing, and uncertainty of revenues and cash flows related to contracts with customers.

ASC 606 allows two methods of adoption: (i) retrospectively to each prior period presented (“full retrospective method”), or (ii) retrospectively with the cumulative effect recognized in retained earnings as of the date of adoption (“modified retrospective method”). Effective upon the start of its first quarter of fiscal 2019, Ciena adopted ASC 606 using the modified retrospective method and accordingly recognized the cumulative effect in accumulated deficit for those contracts that were not completed as of October 31, 2018. Accordingly, results for the reporting periods after October 31, 2018 are presented under ASC 606, while prior periods have not been adjusted and continue to be reported in accordance with Ciena’s historical revenue recognition practices. Refer to Opening Balance Adjustments below for the impact of ASC 606 adoption on Ciena’s Condensed Consolidated Financial Statements. In connection with its adoption of ASC 606, Ciena has implemented new accounting policies and processes, and incorporated such into its existing internal control environment as necessary to support the requirements of ASC 606.

Revenue Recognition Timing Differences

The adoption of ASC 606 requires Ciena to recognize revenue when the customer obtains control of promised products or services in an amount that reflects the consideration that Ciena would expect to receive in exchange for those products or services. Under the prior revenue standard, the timing of revenue recognition for delivered products or services was limited to

8

such amount not contingent upon future delivery of products or service or future performance obligations, or subject to customer-specified return or privileges. In the case of multiple element software arrangements for which vendor-specific objective evidence (“VSOE”) of undelivered maintenance did not exist, under the prior revenue standard, Ciena recognized revenue for the entire arrangement over the maintenance term. The adoption of ASC 606 requires Ciena to determine the stand-alone selling price for each of the software and software-related deliverables of such multiple element arrangements at contract inception. Consequently, under ASC 606, certain software deliverables will be recognized at a point in time rather than over a period of time. In addition, under ASC 606, certain installation and deployment, and consulting and network design services, will be recognized over a period of time rather than at a point in time.

Revenue Recognition Policy Under ASC 606

Ciena recognizes revenue when control of the promised products or services is transferred to its customer, in an amount that reflects the consideration that Ciena expects to be entitled to in exchange for those products or services.

Ciena determines revenue recognition by applying the following five-step approach:

•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 the performance obligations in the contract; and

•recognition of revenue when, or as, Ciena satisfies a performance obligation.

Generally, Ciena makes sales pursuant to purchase orders placed by customers under framework agreements that govern the general commercial terms and conditions of the sale of our products and services. These purchase orders under framework agreements are used to determine the identification of the contract or contracts with this customer. Purchase orders typically include the description, quantity, and price of each product or service purchased. Purchase orders may include one-line bundled pricing for both products and services. Accordingly, purchase orders can include various combinations of products and services that are generally distinct and accounted for as separate performance obligations. Ciena evaluates each promised product and service offering to determine whether it represents a distinct performance obligation. In doing so, Ciena considers, among other things, customary business practices, whether the customer can benefit from the product or service on its own or together with other resources that are readily available, and whether Ciena’s commitment to transfer the product or service to the customer is separately identifiable from other obligations in the purchase order. For transactions where Ciena delivers the product or services, Ciena is typically the principal and records revenue and costs of goods sold on a gross basis.

Purchase orders are invoiced based upon the terms set forth either in the purchase order or the framework agreement, as applicable. Generally, sales of products and software licenses are invoiced upon shipment or delivery. Maintenance and software subscription services are invoiced quarterly or annually in advance of the service term. Ciena’s other service offerings are generally invoiced upon completion of the service. Payment terms and cash received typically range from 30 to 90 days from the invoicing date. Historically, Ciena has not provided any material financing arrangements to its customers. As a practical expedient, Ciena does not adjust the amount of consideration it will receive for the effects of a significant financing component as it expects, at contract inception, that the period between Ciena transfer of the products or services to the customer, and customer payment for the products or services will be one year or less. Shipping and handling fees invoiced to customers are included in revenue, with the associated expense included in product cost of goods sold. Ciena records revenue net of any associated sales taxes.

Ciena recognizes revenue upon the transfer of control of promised products or services to a customer. Transfer of control occurs once the customer has the contractual right to use the product, generally upon shipment or delivery to the customer. Transfer of control can also occur over time for services such as software subscription, maintenance, installation, and various professional services as the customer receives the benefit over the contract term.

Significant Judgments

Revenue is allocated among performance obligations based on standalone selling price (“SSP”). SSP reflects the price that Ciena would expect to sell that product or service on a stand alone basis at contract inception and be entitled to receive for the promised products or services. SSP is estimated for each distinct performance obligation and judgment may be required in its determination. The best evidence of SSP is the observable price of a product or service when Ciena sells the products separately in similar circumstances and to similar customers. In instances where SSP is not directly observable, Ciena determines SSP using information that may include market conditions and other observable inputs.

9

Ciena applies judgment in determining the transaction price as Ciena may be required to estimate variable consideration when determining the amount of revenue to recognize. Variable consideration can include various rebate, cooperative marketing, and other incentive programs that Ciena offers to its distributors, partners and customers. When determining the amount of revenue to recognize, Ciena estimates the expected usage of these programs, applying the expected value or most likely estimate and updates the estimate at each reporting period as actual utilization becomes available. Ciena also considers any customer right of return and any actual or potential payment of liquidated damages, contractual or similar penalties, or other claims for performance failures or delays in determining the transaction price, where applicable.

When transfer of control is judged to be over time for installation and professional service arrangements, Ciena applies the input method to determine the amount of revenue to be recognized in a given period. Utilizing the input method, Ciena recognizes revenue based on the ratio of actual costs incurred to date to the total estimated costs expected to be incurred. Revenue for software subscription and maintenance is recognized ratably over the period during which the services are performed.

Capitalized Contract Acquisition Costs

Ciena has considered the impact of the guidance in ASC 340-40, Other Assets and Deferred Costs; Contracts with Customers, and the interpretations of the FASB Transition Resource Group for Revenue Recognition (“TRG”) with respect to capitalization and amortization of incremental costs of obtaining a contract. In conjunction with this interpretation, Ciena considers each customer purchase in combination with the corresponding framework agreement, if applicable, as a contract. Ciena has elected to implement the practical expedient, which allows for incremental costs to be recognized as an expense when incurred if the period of the asset recognition is one year or less. If the period of the asset recognition is greater than one year, Ciena amortizes these costs over the period of performance. Ciena considers sales commissions incurred upon receipt of purchase orders placed by customers as incremental costs to obtain such purchase orders. The practical expedient method is applied to the purchase order as a whole and thus the capitalized costs of obtaining a purchase order is applied even if the purchase order contains more than one performance obligation. In cases where a purchase order includes various distinct products or services, with both short-term (one year or less) and long-term (more than a year) performance periods, the cost of commissions incurred for the total value of the purchase order is capitalized and subsequently amortized as each performance obligation is recognized.

For the additional disclosures required as part of ASC 606 see Note 3 below.

Impact of ASC 606 Adoption

The following table summarizes the impact of adopting ASC 606 on Ciena’s Condensed Consolidated Statement of Operations (in millions):

	Quarter Ended January 31, 2019
	As Reported		Adjustments			Balances without adoption of ASC 606
Total revenue	$	778,527	$	(10,900	)	$	767,627
Total cost of goods sold	$	455,186	$	(9,129	)	$	446,057
Net income	$	33,616	$	(399	)	$	33,217
Diluted net income per potential common share	$	0.21	$	—		$	0.21

The increase in revenue from adoption of ASC 606 was primarily the result of installation and deployment services, where revenue was recognized over a period of time rather than at a point in time under the prior revenue recognition standard. The adoption of ASC 606 did not have a material impact to Ciena’s Condensed Consolidated Balance Sheet or any impact on net cash provided by operating activities as of January 31, 2019. See “Revenue Recognition Timing Differences” above. For additional information regarding ASC 606, see Note 3 below.

(1) Unpaid accounts receivable and related deferred revenue related to rights and obligations in a contract are interdependent and therefore recorded net within Ciena’s balance sheet. This represents an increase of $12.5 million from the reversal of certain net unpaid accounts receivable and related deferred revenue.

(2) Represents a decrease of $2.5 million in deferred costs of goods sold due to change in revenue recognition for certain product sales.

(3) Represents increases of $27.5 million in unbilled accounts receivable for change in recognizing revenue for installation services, $3.9 million in unbilled accounts receivable from change in recognizing revenue for certain product sales and $9.6 million related to short-term capitalized acquisition costs (e.g., commissions) and a decrease of $19.5 million related to prepaid cost of installation services.

(4) Represents a decrease of $14.4 million in deferred tax asset, net, related to the unrecognized income tax effects of the net adjustments from the new revenue recognition standard.

(5) Represents an increase of $4.0 million related to long-term capitalized acquisition costs (e.g., commissions).

(6) Represents decreases of $23.6 million in deferred revenue primarily due to a change in revenue recognition for certain multiple-element software arrangements and $1.7 million in deferred revenue primarily due to a change in revenue recognition for certain product sales and increases of $2.7 million for a change in revenue recognition from certain maintenance services and $8.2 million from the reversal of balance sheet netting for certain unpaid invoices included in accounts receivable, net and deferred revenue.

(7) Represents a decrease of $18.6 million in long-term deferred revenue primarily due to a change in revenue recognition for certain multiple-element software arrangements and an increase of $4.3 million from the reversal of balance sheet netting for certain unpaid invoices included in accounts receivable, net and long-term deferred revenue.

(8) Accumulated deficit impact from the adjustments noted above.

Intangibles

In August 2018, the FASB issued ASU No. 2018-15 (“ASU 2018-15”), Intangibles - Goodwill and Other-Internal-Use Software which aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. Ciena

11

adopted ASU 2018-15 during the first quarter of fiscal 2019. The application of this accounting standard did not have a material impact on Ciena's Condensed Consolidated Financial Statements.

Newly Issued Accounting Standards - Not Yet Effective

In February 2016, the FASB issued ASU No. 2016-02 (“ASU 2016-02”), Leases, which requires an entity to recognize assets and liabilities on the balance sheet for the rights and obligations created by leased assets and to provide additional disclosures. ASU 2016-02 is effective for Ciena beginning in the first quarter of fiscal 2020. Under current GAAP, the majority of Ciena’s leases for its properties are considered operating leases, and Ciena expects that the adoption of this ASU will require these leases to be classified as financing leases and to be recognized as assets and liabilities on Ciena’s balance sheet. Ciena is continuing to evaluate other possible impacts of the adoption of ASU 2016-02 on its Consolidated Financial Statements and disclosures.

In August 2018, the FASB issued ASU No. 2018-13 (“ASU 2018-13”), Fair Value Measurement (Topic 820): Disclosure Framework which modifies the disclosure requirements on fair value measurements. ASU 2018-13 is effective for Ciena beginning in the first quarter of fiscal year 2020, early adoption is permitted. Ciena is currently evaluating this guidance to determine the impact on its 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 January 31, 2019		Adjusted Balance at November 1, 2018
Accounts receivable, net	$	761,186	$	799,011
Contract assets	$	47,542	$	31,380
Deferred revenue	$	136,141	$	140,704

Our contract assets represent unbilled accounts receivable 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 services arrangements where transfer of control has occurred but Ciena has not yet invoiced the customer.

14

Contract liabilities consist of deferred revenue and represent advanced payments against non-cancelable customer orders received prior to revenue recognition. Ciena recognized approximately $39.4 million of revenue during the first three months of fiscal 2019 that was included in the deferred revenue balance at November 1, 2018. Revenue recognized due to changes in transaction price from performance obligations satisfied or partially satisfied in previous periods were immaterial in the first quarter of fiscal 2019.

Capitalized Contract Acquisition Costs

Capitalized contract acquisition costs consist of deferred sales commissions and were $12.4 million and $13.6 million as of January 31, 2019 and November 1, 2018, respectively, and were included in other current assets and other assets. The amortization expense associated with these costs was $4.1 million during the first three months of fiscal 2019 and was included in sales and marketing expense.

Remaining Performance Obligations

Remaining Performance Obligations (RPO) are comprised of non-cancelable customer purchase orders for products and services that are awaiting transfer of control for revenue recognition under the applicable contract terms. As of January 31, 2019, the aggregate amount of RPO was $1.07 billion. As of January 31, 2019, Ciena expects approximately 80% of the RPO to be recognized as revenue within the next twelve months.

(4) RESTRUCTURING COSTS

Ciena has undertaken a number of restructuring activities intended to reduce expense and to better 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 for the three months ended January 31, 2019 (in thousands):

	Workforce reduction				Consolidation of excess facilities				Total

(1) Reflects a global workforce reduction of approximately 100 employees during the first quarter of fiscal 2018 as part of a business optimization strategy to improve gross margin, constrain operating expense and redesign certain business processes.

(2) Reflects unfavorable lease commitments in connection with a portion of facilities located in Petaluma, California.

(5) INTEREST AND OTHER INCOME, NET

The components of interest and other income, net, are as follows (in thousands):

	Quarter Ended January 31,
	2019			2018
Interest income	$	3,872		$	2,444
Gains (losses) on non-hedge designated foreign currency forward contracts	22			(699		)
Foreign currency exchange gains	783			13
Other	(424		)	(183		)
Interest and other income, net	$	4,253		$	1,575

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 $0.8 million in foreign currency exchange rate gains during the first three months of fiscal 2019 as a result of monetary assets and liabilities that were transacted in a currency other than the entity’s functional currency, and the remeasurement adjustments were recorded in interest and other income, net on the Condensed Consolidated Statements of Operations. Ciena recorded minimal gains in foreign currency exchange rates for the first three months of fiscal 2018. 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, net on the Condensed Consolidated Statements of Operations. During the first three months of fiscal 2019, Ciena recorded minimal gains from non-hedge designated foreign currency forward contracts. During the first three months of fiscal 2018, Ciena recorded losses of $0.7 million from non-hedge designated foreign currency forward contracts.

(6)  INCOME TAXES

On December 22, 2017, the Tax Cuts and Jobs Act (the "Tax Act") was enacted. The Tax Act significantly revises the U.S. corporate income tax by, among other things, lowering the statutory corporate income tax rate (“federal tax rate”) from 35% to 21% effective January 1, 2018, implementing a modified territorial tax system, and imposing a mandatory one-time transition tax on accumulated earnings of foreign subsidiaries. The enactment of the Tax Act resulted in Ciena recording a provisional tax expense of $472.8 million in fiscal 2018. In the first quarter of fiscal 2019, the measurement period under the Tax Act concluded, which resulted in immaterial adjustments to our provisional estimates. In addition, the realizability of U.S. tax carryforwards is not impacted by the base erosion and anti-abuse tax (BEAT), and the BEAT is a period cost when incurred.

The effective tax rate for the three months ended January 31,2019 was lower than the effective tax rate for the three months ended January 31,2018, primarily due to the impact of the Tax Act which reduced the U.S. federal corporate income tax rate from 35% to 21% effective January 1, 2018. The reduction of the U.S. federal corporate income tax rate during the three months ended January 31, 2018, required the remeasurement of the net deferred tax assets and liabilities (“DTA”). Also, Ciena recorded U.S. transition tax in the three months ended January 31, 2018.

18

Ciena did not have any transfers between Level 1 and Level 2 fair value measurements during the periods presented.

Ciena’s Level 3 liability is included in both accrued liabilities and other long-term obligations and reflects a contingent consideration element of a three-year payout arrangement associated with Ciena’s purchase of DonRiver in the fourth quarter of fiscal 2018. The contingent consideration is valued by applying the income approach based upon a discounted cash flow technique using Monte Carlo simulations. As of January 31, 2019, there was no material change to the fair value.

(9) INVENTORIES

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

	January 31, 2019			October 31, 2018
Raw materials	$	75,525		$	67,468
Work-in-process	10,045			9,589

Provision for excess and obsolescence	(49,017		)	(50,938		)
	$	323,106		$	262,751

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 and market conditions. During the first three months of fiscal 2019, Ciena recorded a provision for excess and obsolescence of $4.7 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.

(10) PREPAID EXPENSES AND OTHER

As of the dates indicated, prepaid expenses and other are comprised of the following (in thousands):

	January 31, 2019		October 31, 2018

Other	109,052		107,932
	$	272,712	$	340,075

⁽¹⁾ Reduction is primarily due to the timing of bonus payments to employees under Ciena's annual cash incentive compensation plan.

The following table summarizes the activity in Ciena’s accrued warranty for the fiscal periods indicated (in thousands):

Three Months Ended January 31,	Beginning Balance		Current Period Provisions	Settlements		Ending Balance
2018	$	42,456	4,657	(4,587	)	$	42,526
2019	$	44,740	3,891	(4,183	)	$	44,448

Settlement of Conversions of New Notes

Debt Conversion Liability Associated With 3.75% Convertible Senior Notes due October 15, 2018 (“New Notes”)

The New Notes provided Ciena the option, at its election, to settle conversions of such notes for cash, shares of its common stock, or a combination of cash and shares equal to the aggregate amount due upon conversion. On August 30, 2018, Ciena notified the noteholders that it had elected to settle conversion of the New Notes in a combination of cash and shares, provided that the cash portion would not exceed an aggregate amount of $400 million. Ciena became obligated to settle a portion of the conversion feature in cash and reclassified the cash conversion feature from equity to a derivative liability at its fair value of $164.2 million. On November 15, 2018, Ciena paid approximately $111.3 million in cash and issued 1.6 million shares in settlement of this embedded conversion feature.

(12) DERIVATIVE INSTRUMENTS

Foreign Currency Derivatives   

As of January 31, 2019 and October 31, 2018, Ciena had forward contracts to hedge its foreign exchange exposure in order to reduce the variability in its Canadian Dollar and Indian Rupee denominated expense, which principally relates to research and development activities. The notional amount of these contracts was approximately $155.7 million and $163.2 million as of January 31, 2019 and October 31, 2018, respectively. These foreign exchange contracts have maturities of 24 months or less and have been designated as cash flow hedges.

During the first three months of fiscal 2019 and fiscal 2018, in order to hedge foreign exchange exposures of certain balance sheet items, Ciena entered into forward contracts to mitigate risk due to variability in the Brazilian Real, Canadian Dollar, Euro, Australian Dollar and British Pound Sterling. The notional amount of these contracts was approximately $120.0 million and $162.6 million as of January 31, 2019 and October 31, 2018, 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 14 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 million of the 2025 Term Loan at 2.957% through September 2023. The total notional amount of interest rate swaps in effect was $350.0 million as of January 31, 2019 and October 31, 2018.

20

Ciena expects the variable rate payments to be received under the terms of the interest rate swaps to offset exactly the forecasted variable rate payments on the equivalent notional amounts of the term loans. 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 5 and Note 8 above.

(14)  SHORT-TERM AND LONG-TERM DEBT

Outstanding Term Loan Payable

2025 Term Loan

The net carrying value of Ciena’s Term Loan due September 28, 2025 (the “2025 Term Loan”) was comprised of the following for the fiscal periods indicated (in thousands):

	January 31, 2019		October 31, 2018
Term Loan Payable due September 28, 2025	$	691,939	$	693,450

21

Deferred debt issuance costs that were deducted from the carrying amounts of the 2025 Term Loan totaled $4.1 million at January 31, 2019 and $4.3 million at October 31, 2018. Deferred debt issuance costs are amortized using the straight-line method, which approximates the effect of the effective interest rate method, 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 $0.2 million during the first three months of fiscal 2019. The carrying value of the 2025 Term Loan listed above is also net of any unamortized debt discounts.    

The principal balance, unamortized debt discount, deferred debt issuance costs, net carrying value and fair value of the 2025 Term Loan were as follows as of January 31, 2019 (in thousands):

	Principal Balance		Unamortized Debt Discount			Deferred Debt Issuance Costs			Net Carrying Value		Fair Value(1)
Term Loan Payable due September 28, 2025	$	698,250	$	(2,215	)	$	(4,096	)	$	691,939	$	694,759

(1) The 2025 Term Loan is categorized as Level 2 in the fair value hierarchy. Ciena estimated the fair value of the 2025 Term Loan using a market approach based upon observable inputs, such as current market transactions involving comparable securities.

(15)  EARNINGS PER SHARE CALCULATION

The following table (in thousands except per share amounts) is a reconciliation of the numerator and denominator of the basic net income (loss) per common share (“Basic EPS”) and the diluted net income (loss) per potential common share (“Diluted EPS”). Basic EPS is computed using the weighted average number of common shares outstanding. Diluted EPS is computed using the weighted average number of the following, in each case, to the extent 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.

	Quarter Ended January 31,

(16)  STOCKHOLDERS’ EQUITY

Stock Repurchase Program

On December 13, 2018, Ciena announced that its Board of Directors authorized a program to repurchase up to $500 million of Ciena’s common stock. The amount and timing of repurchases are subject to a variety of factors including liquidity, cash flow, stock price and general business and market conditions. The program may be modified, suspended, or discontinued at any time.

A summary of the stock repurchase program, reported based on trade date, is summarized as follows:

22

	Shares Repurchased	Weighted-Average Price per Share		Amount Repurchased (in thousands)
Cumulative balance at October 31, 2018	—	$	—	$	—
Repurchase of common stock under the stock repurchase program	591,897	35.75		21,162
Cumulative balance at January 31, 2019	591,897	$	35.75	$	21,162

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 common stock to satisfy employee tax withholding obligations due upon vesting of stock unit awards. The purchase price of $10.0 million for the shares of Ciena’s stock repurchased during the first quarter of fiscal 2019 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.

(17) SHARE-BASED COMPENSATION EXPENSE

The following table summarizes share-based compensation expense for the periods indicated (in thousands):

	Quarter Ended January 31,
	2019		2018
Product costs	$	637	$	672
Service costs	770		625
Share-based compensation expense included in cost of sales	1,407		1,297
Research and development	3,391		3,255
Sales and marketing	3,785		3,328
General and administrative	5,112		4,474
Share-based compensation expense included in operating expense	12,288		11,057
Share-based compensation expense capitalized in inventory, net	60		39
Total share-based compensation	$	13,755	$	12,393

As of January 31, 2019, total unrecognized share-based compensation expense was approximately $119.7 million which relates to unvested stock unit awards and is expected to be recognized over a weighted-average period of 1.7 years.

(19)  COMMITMENTS AND CONTINGENCIES

Canadian Grant

25

During fiscal 2018, Ciena entered into agreements related to the Evolution of Networking Services through a Corridor in Quebec and Ontario for Research and Innovation (“ENCQOR”) project with the Canadian federal government, the government of the province of Ontario and the government of the province of Quebec to develop a 5G technology corridor between Quebec and Ontario to promote research and development, small business enterprises and entrepreneurs in Canada. Under these agreements, Ciena can receive up to an aggregate CAD$57.6 million (approximately $44.0 million) in reimbursement from the three Canadian government entities for eligible costs over a period commencing on February 20, 2017 and ending on March 31, 2022. Ciena anticipates receiving recurring disbursements over this period. Amounts received under the agreements are subject to recoupment in the event that Ciena fails to achieve certain minimum investment, employment and project milestones. As of January 31, 2019, Ciena recorded a CAD$19.1 million (approximately $14.8 million) benefit as a reduction in research and development expense of which CAD$2.5 million (approximately $1.9 million) was recorded in the first three months of fiscal 2019. As of January 31, 2019, amounts receivable from this grant were CAD$10.1 million (approximately $7.7 million).

Foreign Tax Contingencies

Ciena is subject to various tax liabilities arising in the ordinary course of business. Ciena does not expect that the ultimate settlement of these tax liabilities will have a material effect on its results of operations, financial position or cash flows.

Litigation

As a result of the acquisition of Cyan in August 2015, Ciena became a defendant in a securities class action lawsuit. On April 1, 2014, the first of two purported stockholder class action lawsuits was filed in the Superior Court of California, County of San Francisco, against Cyan, the members of Cyan’s board of directors, Cyan’s former Chief Financial Officer, and the underwriters of Cyan’s initial public offering. The cases were consolidated as Beaver County Employees Retirement Fund, et al. v. Cyan, Inc. et al., Case No. CGC-14-538355. The consolidated complaint alleges violations of federal securities laws on behalf of a purported class consisting of purchasers of Cyan’s common stock pursuant or traceable to the registration statement and prospectus for Cyan’s initial public offering in April 2013, and seeks unspecified compensatory damages and other relief. On May 19, 2015, the proposed class was certified. During the fourth quarter of fiscal 2018, the parties agreed to the terms of a settlement of the action, which settlement is subject to notice to class members and approval by the court. The terms of the proposed settlement, which include a release and dismissal of all claims against all defendants without any liability or wrongdoing attributed to them, are not material to the Ciena’s financial results. There is no assurance that the court will ultimately approve the settlement.

Internal Investigation

During fiscal 2017, one of Ciena’s third-party vendors raised allegations about certain questionable payments to one or more individuals employed by a customer in a country in the ASEAN region. Ciena promptly initiated an internal investigation into the matter, with the assistance of outside counsel, which investigation corroborated direct and indirect payments to one such individual and sought to determine whether the payments may have violated applicable laws and regulations, including the U.S. Foreign Corrupt Practices Act (“FCPA”). In September 2017, Ciena voluntarily contacted the SEC and the U.S. Department of Justice (“DOJ”) to advise them of the relevant events and the findings of Ciena’s internal investigation. On December 10, 2018, the DOJ advised that it has declined to prosecute this matter and that its investigation into the matter is now closed. Ciena continues to cooperate fully with the SEC in its investigation into this matter.

Ciena’s operations in the relevant country constituted less than 1.5% of consolidated revenues as reported by Ciena in each fiscal year from 2012 through 2017. Ciena does not currently anticipate that this matter will have a material adverse effect on its business, financial condition or results of operations. However, as discussions with the SEC are ongoing, the ultimate outcome of this matter cannot be predicted at this time. As of the filing of this report, no provision with respect to this matter has been made in Ciena’s consolidated financial statements. Any determination that Ciena’s operations or activities are not in compliance with the FCPA or other applicable laws or regulations could result in the imposition of fines, civil and criminal penalties, and equitable remedies, including disgorgement or injunctive relief.

In addition to the matters described in “Litigation” and “Internal Investigation” above, Ciena is subject to various legal proceedings, claims and other matters arising in the ordinary course of business, including those that relate to employment, commercial, tax and other regulatory matters. 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. Ciena does not expect that the ultimate costs to resolve such matters will have a material effect on its results of operations, financial position or cash flows.

26

(20) SUBSEQUENT EVENTS

Stock Repurchase Program

From the end of the first quarter of fiscal 2019 through March 6, 2019, Ciena repurchased an additional 390,902 shares of its common stock, for an aggregate purchase price of $15.8 million at an average price of $40.54 per share, inclusive of repurchases pending settlement. As of March 6, 2019, Ciena has repurchased an aggregate of 982,799 shares and has an aggregate of $463.0 million of authorized funds remaining under its Stock Repurchase Program.

Increased Stock Repurchase Program. On December 13, 2018, we announced that our Board of Directors authorized a new program to repurchase up to $500 million of our common stock. This program replaces our previously authorized repurchase program, under which we were authorized to repurchase up to $300 million of our common stock through the end of fiscal 2020. We may purchase shares at management’s discretion in the open market, in privately negotiated transactions, in transactions structured through investment banking institutions, or a combination of the foregoing. We may also, from time to time, enter into Rule 10b5-1 plans to facilitate repurchases of shares under this authorization. The amount and timing of repurchases are subject to a variety of factors including liquidity, cash flow, stock price and general business and market conditions. The program may be modified, suspended, or discontinued at any time. For additional information, including our repurchase activities under the previously authorized program, see Note 16 and Note 20 to our Condensed Consolidated Financial Statements included in Item 1 of Part I of this report and Item 2 of Part II of this report.

Settlement Upon Conversion of 3.75% Convertible Senior Notes due October 15, 2018 (New). During the fourth quarter of fiscal 2018, we elected to settle conversion of our 3.75% Convertible Senior Notes due October 15, 2018 (New) (the “New Notes”) in a combination of cash and shares, provided that the cash portion would not exceed an aggregate amount of approximately $400 million. Upon conversion of the New Notes by the holders in advance of maturity, on October 15, 2018, we paid in cash an amount of $288.7 million representing the aggregate principal amount outstanding of the New Notes. The New Notes thereafter ceased to be outstanding. In addition, because Ciena common stock traded in excess of the $20.17 per share conversion price during an observation period from October 15, 2018 through November 9, 2018, on November 15, 2018, we paid an additional $111.3 million in cash and issued approximately 1.6 million shares with respect to the “in the money” portion of the notes in settlement of the conversion. See Note 11 to our Condensed Consolidated Financial Statements included in Item 1 of Part I of this report for more information relating to the settlement of our New Notes.

Consolidated Results of Operations

Operating Segments

We have the following operating segments for reporting purposes: (i) Networking Platforms; (ii) Software and Software-Related Services; and (iii) Global Services. See Note 3 to our Condensed Consolidated Financial Statements included in Item 1 of Part I of this report.

Quarter ended January 31, 2019 compared to the quarter ended January 31, 2018

As of the first quarter of fiscal 2019, we adopted ASC 606 using the modified retrospective method. See Notes 2 and 3 to our Condensed Consolidated Financial Statements included in Item 1 of Part I of this report for the impact of this adoption on our financial results.

Revenue

During the first quarter of fiscal 2019, approximately 17.7% of our revenue was non-U.S. Dollar denominated, including sales in Euros, Japanese Yen, Canadian Dollars, Brazilian Reais, British Pounds and Indian Rupee. During the first quarter of fiscal 2019, as compared to the first quarter of fiscal 2018, the U.S. Dollar fluctuated against these currencies. Consequently, our revenue reported in U.S. Dollars slightly decreased by approximately $9.2 million, or 1.2%, as compared to the first quarter of fiscal 2018, due to fluctuations in foreign currency. The table below (in thousands, except percentage data) sets forth the changes in our operating segment revenue for the periods indicated:

• Networking Platforms segment revenueincreased, primarily reflecting product line sales increases of $121.6 million of our Converged Packet Optical products and $2.9 million of our Packet Networking products.

◦ Converged Packet Optical sales primarily reflect sales increases of $79.3 million of our Waveserver stackable interconnect system and $53.6 million of our 6500 Packet-Optical Platform. These increases were partially offset by a sales decrease of $12.6 million of our 5410/5430 Reconfigurable Switching Systems. Waveserver

30

stackable interconnect system sales reflect increased sales to Web-scale providers, which represent a growing portion of our business as our business continues to diversify. The sales increase of our 6500 Packet-Optical Platform is primarily due to increased sales to AT&T and other communications service providers, partially offset by decreased sales to Web-scale providers.

◦ Packet Networking sales increased, primarily reflecting $17.9 million in initial sales of our 6500 Packet Transport System, partially offset by a sales decrease of $15.1 million of our 3000 and 5000 families of service delivery and aggregation switches, primarily due to decreased sales to AT&T and other communications service providers.

◦ Software and Software-Related Services segment revenue increased, primarilyreflecting a sales increase of $5.6 million of our Blue Planet Automation Software and Services, partially offset by a sales decrease of $2.5 million of our Platform Software and Services. The increase in our Blue Planet Automation Software and Services includes sales of $4.9 million and $3.0 million related to the Packet Design and DonRiver businesses acquired during fiscal 2018, respectively.

• Global Servicessegment revenue increased, primarily reflecting sales increases of $5.3 million of our maintenance support and training services.

Our operating segments engage in business and operations across four geographic regions: North America; Europe, Middle

East and Africa (“EMEA”); Caribbean and Latin America (“CALA”); and Asia Pacific and India (“APAC”). Results for North

America include only activities in the U.S. and Canada. The following table reflects our geographic distribution of revenue

principally based on the relevant location for our delivery of products and performance of services. Our revenue, when

considered by geographic distribution, can fluctuate significantly, and the timing of revenue recognition for large network

projects, particularly outside of North America, can result in large variations in geographic revenue results in any particular

quarter. The table below (in thousands, except percentage data) sets forth the changes in geographic distribution of revenue for the periods indicated:

	Quarter Ended January 31,						Increase

• North America revenue primarily reflects an increase of $84.4 million within our Networking Platforms segment. This increase primarily reflects product line sales increases of $73.9 million of Converged Packet Optical products and $10.5 million of Packet Networking products. Converged Packet Optical sales primarily reflects sales increases of $48.4 million of our Waveserver stackable interconnect system and $26.2 million of our 6500 Packet-Optical Platform. Waveserver stackable interconnect system sales reflect increased sales to Web-scale providers. 6500 Packet-Optical Platform sales reflect increased sales to AT&T and other communications service providers, partially offset by decreased sales to Web-scale providers.

• EMEA revenue primarilyreflects increases of $25.7 million within our Networking Platforms segment and $4.5 million within our Global Services segment. Networking Platforms revenue primarily reflects a sales increase of $25.4 million of our Waveserver stackable interconnect system to Web-scale providers.

• CALA revenue primarilyreflects decreases of $2.2 million within our Networking Platforms segment and $2.1 million within our Global Services segment.

• APAC revenue primarily reflects increases of $16.6 million within our Networking Platforms segment, $3.4 million within our Software and Software-Related Services segment and $2.0 million within our Global Services segment. APAC revenue primarily represents increases in sales in Japan and India of $11.7 million and $7.4 million, respectively. Networking Platforms segment revenue primarily reflects a product line increase of $24.6 million in Converged Packet Optical sales primarily due to an increase of $32.4 million in sales of our 6500 Packet-Optical Platform to communications service providers and submarine network operators. This increase was partially offset by

31

a decrease of $11.2 million in sales of our 5410/5430 Reconfigurable Switching Systems to communications service providers.

Cost of Goods Sold and Gross Profit

Product cost of goods sold consists primarily of amounts paid to third-party contract manufacturers, component costs,

employee-related costs and overhead, shipping and logistics costs associated with manufacturing-related operations, warranty

and other contractual obligations, royalties, license fees, amortization of intangible assets, cost of excess and obsolete inventory

and, when applicable, estimated losses on committed customer contracts.

Services cost of goods sold consists primarily of direct and third-party costs associated with our provision of services

including installation, deployment, maintenance support, consulting and training activities and, when applicable, estimated

losses on committed customer contracts. The majority of these costs relate to personnel, including employee and third-party

contractor-related costs.

Our gross profit as a percentage of revenue, or “gross margin,” can fluctuate due to a number of factors, particularly when

viewed on a quarterly basis. Our gross margin can fluctuate and be adversely impacted depending upon our revenue

concentration within a particular segment, product line, geography, or customer, including our success in selling software in a

particular period. Our gross margin remains highly dependent on our continued ability to drive product cost reductions relative

to the price erosion that we regularly encounter in our markets. Moreover, we are often required to compete with aggressive

pricing and commercial terms and, to secure business with new and existing customers, we may agree to pricing or other

unfavorable commercial terms that adversely affect our gross margin. When we have success in taking share and winning new

business, it can result in additional pressure on gross margin from these pricing dynamics and the early stages of these network

deployments. Early stages of new network builds also often include an increased concentration of lower margin “common”

equipment sales and installation services, with the intent to improve margin as we sell channel cards and maintenance services

to customers adding capacity or services to their networks. Gross margin can be impacted by technology-based price

compression and the introduction or substitution of new platforms with improved price for performance as compared to existing

solutions that carry higher margins. Gross margin can also be impacted by changes in expense for excess and obsolete

inventory and warranty obligations.

Service gross margin can be affected by the mix of customers and services, particularly the mix between deployment and

maintenance services, geographic mix and the timing and extent of any investments in internal resources to support this

business.

The tables below (in thousands, except percentage data) set forth the changes in revenue, cost of goods sold, and gross profit for the periods indicated:

• Gross profit as a percentage of revenue reflects reduced service gross profits partially offset by improved product gross profits as described below. We encountered fluctuations or reductions in our gross margin during fiscal 2018 as a result of our strategy to leverage our technology leadership and to aggressively capture additional market share and displace competitors, particularly with communications service providers internationally. We were successful in executing our strategy during fiscal 2018, which allowed us to achieve meaningful revenue growth and additional market share, but which adversely impacted gross margins. Our continued success in implementing this strategy may require that we agree to aggressive pricing, commercial concessions and other unfavorable terms, and result in an increased mix of revenues from early stage deployments, any or all of which may result in low or negative gross margins on a particular order or group of orders.

• Gross profit on products as a percentage of product revenue increased, primarily due to product cost reductions, improved manufacturing efficiencies and reduced inventory obsolescence expense. This benefit was partially offset by market-based price erosion we encountered during the period.

• Gross profit on services as a percentage of services revenue decreased, primarily as a result of reduced margins on our software services, which was primarily due to increased costs related to developing resources to promote our growth strategy and the impact of early stages of international network deployments.

Operating Expense

Operating expense consists of the component elements described below.

• Research and development expense primarily consists of salaries and related employee expense (including share-based compensation expense), prototype costs relating to design, development, product testing, depreciation expense, and third-party consulting costs.

• Selling and marketing expense primarily consists of salaries, commissions and related employee expense (including share-based compensation expense) and sales and marketing support expense, including travel, demonstration units, trade show expense, and third-party consulting costs.

• General and administrative expense primarily consists of salaries and related employee expense (including share-based compensation expense), and costs for third-party consulting and other services.

• Significant asset impairments and restructuring costs primarily reflect actions we have taken to better align our workforce, facilities, and operating costs with perceived market opportunities, business strategies, changes in market and business conditions and significant impairments of assets.

• Amortization of intangible assets primarily reflects the amortization of both purchased technology and the value of customer relationships derived from our acquisitions.

• Acquisition and integration costs consist of expenses for financial, legal and accounting advisors and severance and other employee-related costs associated with our acquisitions of Packet Design and DonRiver, including costs associated with a three-year earn-out arrangement related to the DonRiver acquisition.

During the first quarter of fiscal 2019, approximately 52.0% of our operating expense was non-U.S. Dollar denominated, including expenses in Canadian Dollars, British Pounds, Indian Rupees, Euros, Brazilian Reais and Australian Dollars. During the first quarter of fiscal 2019 as compared to the first quarter of fiscal 2018, the U.S. Dollar fluctuated against these currencies.

33

Consequently, our operating expense reported in U.S. Dollars slightly decreased by approximately $6.2 million, or 2.3%, as compared to the first quarter of fiscal 2018, due to fluctuations in foreign currency. The table below (in thousands, except percentage data) sets forth the changes in operating expense for the periods indicated:

• Research and development expense benefited by$3.6 million as a result of foreign exchange rates, net of hedging, primarily due to a stronger U.S. Dollar in relation to the Canadian Dollar and Indian Rupee. Including the effect of foreign exchange rates, research and development expenses increased by $10.1 million. This increase primarily reflects increases of $5.2 million in professional services, $5.0 million in employee and compensation costs and $1.1 million in prototype expense. These increases were partially offset by a benefit of $1.9 million for the ENCQOR grant reimbursement. For more information on the ENCQOR grant, see Note 19 to our Condensed Consolidated Financial Statements included in Item 1 of Part I of this report.

• Selling and marketing expense benefited by$2.0 million as a result of foreign exchange rates primarily due to a stronger U.S. Dollar in relation to the Euro and Canadian Dollar. Including the effect of foreign exchange rates, sales and marketing expenses increased by $9.6 million, primarily reflecting increases of $6.9 million in employee and compensation costs, $1.0 million in professional services and $1.0 million in travel and entertainment costs.

• General and administrative expense increasedby $0.8 million, primarily reflecting an increase in employee and compensation costs.

• Significant asset impairments and restructuring costs reflect global workforce reductions as part of a business optimization strategy to improve gross margin, constrain operating expense, and redesign certain business processes.

• Amortization of intangible assets increased due to additional intangibles related to our acquisitions of Packet Design and DonRiver.

• Acquisition and integration costs reflect financial, legal and accounting advisors and severance and other employment-related costs related to our acquisitions of Packet Design and DonRiver.

• Interest and other income, net primarily reflects a $1.5 million gain related to foreign exchange rates on assets and liabilities denominated in a currency other than the relevant functional currency, net of hedging activity, and a $1.4 million gain in interest income due to higher interest rates on our investments in the first quarter of fiscal 2019.

• Interest expensedecreased, primarily due to a reduction in our aggregate outstanding debt during the fourth quarter of fiscal 2018.

• Provision for income taxes decreased, as the first fiscal quarter of fiscal 2018 reflects the impact of the Tax Act including $431.3 million in expense for the remeasurement of our net deferred tax assets and a $45.6 million charge related to a transition tax on accumulated historical foreign earnings and their deemed repatriation to the U.S.

• Networking Platforms segment profitincreased, primarily due to higher sales volume and higher gross margin as described above, partially offset by higher research and development costs.

• Software and Software-Related Services segment profitdecreased, primarily due to reduced gross margin on software-related services as described above.

• Global Services segment profit decreased primarily due to reduced gross margin, partially offset by higher sales volume.

Liquidity and Capital Resources

For the three months ended January 31,2019, we used$14.1 million of cash, as our working capital requirements of $108.9 million exceeded our net income (adjusted for non-cash charges) of $94.8 million. The increase in working capital was primarily driven by inventory increases of $67.6 million. For additional details on our cash from operations, see the discussion below entitled “Cash Used In Operations.”

Cash, cash equivalents and investments decreased by $165.4 million during the first three months of fiscal 2019. In addition to the cash used in operations mentioned above, the decrease in cash also reflects (i) cash used for the payment of the debt conversion liability associated with our New Notes of $111.3 million on November 15, 2018, (ii) cash used to fund our investing activities for capital expenditures totaling $15.3 million, (iii) cash used for stock repurchase under our stock repurchase program of $19.7 million and (iv) stock repurchased upon vesting of our stock unit awards to employees relating to tax withholding of $10.0 million. Proceeds from the issuance of equity under our employee stock purchase plans provided $10.9 million in cash during the three months ended January 31,2019.

	January 31, 2019		October 31, 2018		Increase (decrease)
Cash and cash equivalents	$	668,810	$	745,423	$	(76,613	)

Principal Sources of Liquidity. Our principal sources of liquidity on hand include our cash, cash equivalents and investments, which as of January 31, 2019 totaled $788.0 million, as well as the senior secured asset-backed revolving credit facility to which we and certain of our subsidiaries are parties (the “ABL Credit Facility”). The ABL Credit Facility provides for a total commitment of $250 million with a maturity date of December 31, 2020. We principally use the ABL Credit Facility to support the issuance of letters of credit that arise in the ordinary course of our business and thereby to reduce our use of cash required to collateralize these instruments. As of January 31, 2019, letters of credit totaling $68.7 million were collateralized by our ABL Credit Facility. There were no borrowings outstanding under the ABL Credit Facility as of January 31, 2019.

Foreign Liquidity. The amount of cash, cash equivalents, and short-term investments held by our foreign subsidiaries was $67.1 million as of January 31, 2019.We intend to reinvest indefinitely our foreign earnings. If we were to repatriate these

accumulated historical foreign earnings, the estimated amount of unrecognized deferred income tax liability related to foreign

withholding taxes would be approximately $25.0 million.

Stock Repurchase Authorization. On December 13, 2018, Ciena announced that its Board of Directors authorized a program to repurchase up to $500 million of its common stock, which replaced in its entirety the previous stock repurchase program authorized in fiscal 2018. The amount and timing of repurchases are subject to a variety of factors including liquidity, cash flow, stock price and general business and market conditions. The program may be modified, suspended, or discontinued at any time.

Liquidity Position. We regularly evaluate our liquidity position, debt obligations, and anticipated cash needs to fund our operating or investment plans and may consider capital raising and other market opportunities that may be available to us. We regularly evaluate alternatives to manage our capital structure and reduce our debt. Based on past performance and current expectations, we believe that cash from operations, cash, cash equivalents, investments, and other sources of liquidity, including our ABL Credit Facility, will satisfy our working capital needs, capital expenditures, and other liquidity requirements associated with our operations through at least the next 12 months.

Cash Used In Operations

The following sections set forth the components of our $14.1 million of cash used in operating activities during the first three months of fiscal 2019:

Net income (adjusted for non-cash charges)

The following table sets forth our net income (adjusted for non-cash charges) during the period (in thousands):

Working Capital        

We used$108.9 million of cash for working capital during the period. The following tables set forth the major components of the cash used in working capital (in thousands):

36

	Three months ended
	January 31, 2019
Cash provided by accounts receivable	$	38,544
Cash used in inventories	(67,555		)
Cash provided by prepaid expenses and other	1,133
Cash used in accounts payable, accruals and other obligations	(76,351		)
Cash used in deferred revenue	(4,664		)
Total cash used for working capital	$	(108,893	)

As compared to the end of fiscal 2018:

• The $38.5 million of cash provided by accounts receivable during the first three months of fiscal 2019 reflects increased cash collections;

• The $67.6 million of cash used in inventory during the first three months of fiscal 2019 primarily reflects increases in finished goods to meet customer delivery schedules;

• The $1.1 million of cash provided by prepaid expense and other during the first three months of fiscal 2019 primarily reflects lower prepaid value added taxes and lower non-customer receivables, partially offset by increases in contract assets for unbilled accounts receivable due to changes in recognizing revenue for installation services and certain product sales.

• The $76.4 million of cash used in accounts payable, accruals and other obligations during the first three months of fiscal 2019 primarily reflects the timing of bonus payments to employees under our annual cash incentive compensation plan; and

• The $4.7 million of cash used in deferred revenue during the first three months of fiscal 2019 represents a decrease in advanced payments received from customers prior to revenue recognition.

Our days sales outstanding (DSOs) for the first three months of fiscal 2019 were 93 days, and our inventory turns for the first three months of fiscal 2019 were 4.7. The calculation of DSOs includes accounts receivables and contract assets for unbilled receivables included in prepaid expenses and other.

Contractual Obligations

There have been no material changes to our contractual obligations since October 31, 2018. For a summary of our contractual obligations, see Item 7 of Part II of our annual report on Form 10-K for the fiscal year ended October 31, 2018.

Off-Balance Sheet Arrangements

We do not engage in any off-balance sheet financing arrangements. In particular, we do not have any equity interests in so-called limited purpose entities, which include special purpose entities (SPEs) and structured finance entities.

Critical Accounting Policies and Estimates

The preparation of our consolidated financial statements requires that we make estimates and judgments that affect the reported amounts of assets, liabilities, revenue and expense, and related disclosure of contingent assets and liabilities. By their nature, these estimates and judgments are subject to an inherent degree of uncertainty. On an ongoing basis, we reevaluate our estimates, including those related to revenue recognition, share-based compensation, bad debts, inventories, intangible and other long-lived assets, goodwill, income taxes, warranty obligations, restructuring, derivatives and hedging, and contingencies and litigation. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances. 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 from these estimates under different assumptions or conditions. To the extent that there are material differences between our estimates and actual results, our consolidated financial statements will be affected.

Our critical accounting policies and estimates have not changed materially since October 31, 2018, except for items listed below. For a discussion of our critical accounting policies and estimates, see Item 7 of Part II of our annual report on Form 10-K for the fiscal year ended October 31, 2018 (Management’s Discussion and Analysis of Financial Condition and Results of Operations).

Disclosure Controls and Procedures

As of the end of the period covered by this report, we carried out an evaluation under the supervision and with the participation of management, including our Chief Executive Officer and Chief Financial Officer, of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended).
