CIENA CORPORATION
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(unaudited)
(1) INTERIM FINANCIAL STATEMENTS
     The interim financial statements included herein for Ciena Corporation (“Ciena”) have been prepared by Ciena, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission. In the opinion of management, financial statements included in this report reflect all normal recurring adjustments which 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 sheet. Certain information and footnote disclosures normally included in the annual financial statements prepared in accordance with generally accepted accounting principles have been condensed or omitted pursuant to such rules and regulations. However, Ciena believes that the disclosures are adequate to understand the information presented. 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 notes thereto included in Ciena’s annual report on Form 10-K for the fiscal year ended October 31, 2005.
     Ciena has a 52 or 53 week fiscal year, which ends on the Saturday nearest to the last day of October in each year. For purposes of financial statement presentation, each fiscal year is described as having ended on October 31, and each fiscal quarter is described as having ended on January 31, April 30 and July 31 of each fiscal year.
(2) SIGNIFICANT ACCOUNTING POLICIES
Cash and Cash Equivalents
     Ciena considers all highly liquid investments purchased with original maturities of three months or less to be cash equivalents. Restricted cash collateralizing letters of credits are included in other current assets and other long-term assets depending upon the duration of the restriction.
Investments
     Ciena’s short-term and long-term investments are classified as available-for-sale and are reported at fair value, with unrealized gains and losses, net of tax, recorded in accumulated other comprehensive income. Realized gains or losses and declines in value determined to be other than temporary, if any, on available-for-sale securities, are reported in other income or expense as incurred.
     Ciena also has certain other minority equity investments in privately held technology companies. These investments are carried at cost because Ciena owns less than 20% of the voting equity and does not have the ability to exercise significant influence over these companies. These investments are inherently high risk as the markets for technologies or products manufactured by these companies are usually early stage at the time of the investment by Ciena and such markets may never be significant. Ciena could lose its entire investment in some or all of these companies. Ciena monitors these investments for impairment and makes appropriate reductions in carrying values when necessary.
Inventories
     Inventories are stated at the lower of cost or market, with cost determined on the first-in, first-out basis. Ciena records a provision for excess and obsolete inventory whenever an impairment has been identified.
Equipment, Furniture and Fixtures
     Equipment, furniture and fixtures are recorded at cost. Depreciation and amortization are computed using the straight-line method over useful lives of two years to five years for equipment, furniture and fixtures and nine months to ten years for leasehold improvements. Impairments of equipment, furniture and fixtures are determined in accordance with Statement of Financial Accounting Standards (SFAS) No. 144, “Accounting for the Impairment or Disposal of Long-Lived Assets.”
     Internal use software and web site development costs are capitalized in accordance with Statement of Position (SOP) No. 98-1, “Accounting for the Costs of Computer Software Developed or Obtained for Internal Use,” and

6


 

Emerging Issues Task Force (EITF) Issue No. 00-2, “Accounting for Web Site Development Costs.” Qualifying costs incurred during the application development stage, which consist primarily of outside services and purchased software license costs, are capitalized and amortized over the estimated useful life of the asset.
Goodwill and Other Intangible Assets
     Ciena has recorded goodwill and purchased intangible assets as a result of several acquisitions. Ciena accounts for goodwill in accordance with SFAS 142 “Goodwill and Other Intangible Assets,” which requires Ciena to test each reporting unit’s goodwill for impairment on an annual basis, which Ciena has determined to be the last business day of September each year, and between annual tests if events occur or circumstances change that would, more likely than not, reduce the fair value of the reporting unit below its carrying value. Purchased intangible assets are carried at cost less accumulated amortization. Amortization is computed using the straight-line method over the economic lives of the respective assets, generally three to seven years. It is Ciena’s policy to assess periodically the carrying amount of its purchased intangible assets to determine if there has been an impairment to their carrying value. Impairments of other intangibles assets are determined in accordance with SFAS 144.
Concentrations
     Substantially all of Ciena’s cash and cash equivalents, short-term and long-term investments, are maintained at two major U.S. financial institutions. The majority of Ciena’s cash equivalents consist of money market funds and overnight repurchase agreements. Deposits held with banks may exceed the amount of insurance provided on such deposits. Generally, these deposits may be redeemed upon demand and, therefore, bear minimal risk.
     Additionally, Ciena’s access to certain raw materials is dependent upon single and sole source suppliers. The inability of any supplier to fulfill supply requirements of Ciena could affect future results. Ciena relies on a small number of contract manufacturers to perform the majority of the manufacturing operations for its products. If Ciena cannot effectively manage these manufacturers and forecast future demand, or if they fail to deliver products or components on time, Ciena’s business may suffer.
Revenue Recognition
     Ciena recognizes revenue in accordance with Staff Accounting Bulletin (SAB) No. 104, “Revenue Recognition,” which states that revenue is realized or realizable and earned when all of the following criteria are met: persuasive evidence of an arrangement exists; delivery has occurred or services have been rendered; the price to the buyer is fixed and determinable; and collectibility is reasonably assured. In instances where final acceptance of the product, system, or solution is specified by the customer, revenue is deferred until all acceptance criteria have been met. Revenue for maintenance services is generally deferred and recognized ratably over the period during which the services are to be performed.
     Some of Ciena’s communications networking equipment is integrated with software that is essential to the functionality of the equipment. Ciena provides unspecified software upgrades and enhancements related to the equipment through maintenance contracts for these products. For transactions involving the sale of software, revenue is recognized in accordance with SOP 97-2, “Software Revenue Recognition,” including deferral of revenue recognition in instances where vendor specific objective evidence for undelivered elements is not determinable.
     For arrangements that involve the delivery or performance of multiple products, services and/or rights to use assets, except as otherwise covered by SOP 97-2, the determination as to how the arrangement consideration should be measured and allocated to the separate deliverables of the arrangement is determined in accordance with EITF 00-21, “Revenue Arrangements with Multiple Deliverables.” When a sale involves multiple elements, such as sales of products that include services, the entire fee from the arrangement is allocated to each respective element based on its relative fair value and recognized when revenue recognition criteria for each element are met. Fair value for each element is established based on the sales price charged when the same element is sold separately.
Revenue Related Accruals
     Ciena provides for the estimated costs to fulfill customer warranty and other contractual obligations upon the recognition of the related revenue. Such reserves are determined based upon actual warranty cost experience, estimates of component failure rates, and management’s industry experience. Ciena’s sales contracts do not permit the right of return of product by the customer after the product has been accepted.

7


 

Accounts Receivable Trade, Net
     Ciena’s allowance for doubtful accounts is based on its assessment, on a specific identification basis, of the collectibility of customer accounts. Ciena performs ongoing credit evaluations of its customers and generally has not required collateral or other forms of security from its customers. In determining the appropriate balance for Ciena’s allowance for doubtful accounts, management considers each individual customer account receivable in order to determine collectibility. In doing so, management considers creditworthiness, payment history, account activity and communication with such customer. If a customer’s financial condition changes, Ciena may be required to take a charge for an allowance on doubtful accounts. During the first six months of fiscal 2006, Ciena recorded the recovery of doubtful accounts in the amount of $2.9 million as a result of payments of amounts due from customers from whom payment was previously deemed doubtful due to the customers’ financial condition.
Research and Development
     Ciena charges all research and development costs to expense as incurred.
Advertising Costs
     Ciena expenses all advertising costs as incurred.
Share-Based Compensation Expense
     On November 1, 2005, Ciena adopted SFAS 123(R), “Share-Based Payment,” which requires the measurement and recognition of compensation expense, based on estimated fair values, for all share-based awards, made to employees and directors, including stock options, restricted stock, restricted stock units and participation in Ciena’s employee stock purchase plan. In March 2005, the Securities and Exchange Commission issued Staff Accounting Bulletin (SAB) No. 107 relating to SFAS 123(R). Ciena has applied the provisions of SAB 107 in its adoption of SFAS 123(R).
     Ciena adopted SFAS 123(R) using the modified prospective application transition method, which requires the application of the accounting standard as of November 1, 2005, the first day of Ciena’s fiscal year 2006. Ciena’s consolidated financial statements as of and for the second quarter of fiscal 2006 reflect the impact of SFAS 123(R). In accordance with the modified prospective application transition method, Ciena’s consolidated financial statements for prior periods have not been restated to reflect, and do not include, the impact of SFAS 123(R). Share-based compensation expense recognized under SFAS 123(R) for the first six months of fiscal 2006 was $8.1 million, of which $0.3 million was capitalized as part of inventory.
     Prior to the adoption of SFAS 123(R), Ciena accounted for share-based awards to employees and directors using the intrinsic value method in accordance with Accounting Principles Board (APB) Opinion No. 25, “Accounting for Stock Issued to Employees,” as interpreted by FASB Interpretation (FIN) No. 44, “Accounting for Certain Transactions Involving Stock Compensation, an Interpretation of APB Opinion No. 25,” as allowed under SFAS 123, “Accounting for Stock-Based Compensation.” Share-based compensation expense of $5.5 million for the first six months of fiscal 2005 was solely related to share-based awards assumed through acquisitions and restricted stock unit awards that Ciena had been recognizing in its consolidated statement of operations in accordance with the provisions set forth above. Because the exercise price of Ciena’s stock options granted to employees and directors equaled the fair market value of the underlying stock at the grant date, under the intrinsic value method, no share-based compensation expense was otherwise recognized in Ciena’s consolidated statement of operations.
     SFAS 123(R) requires companies to estimate the fair value of share-based awards on the date of grant using an option-pricing model. The value of the portion of the award that is ultimately expected to vest is recognized as expense in Ciena’s consolidated statement of operations over the requisite service periods. Share-based compensation expense recognized in Ciena’s consolidated statement of operations for the second quarter and first six months of fiscal 2006 includes compensation expense for share-based awards granted (i) prior to, but not yet vested as of October 31, 2005, based on the grant date fair value estimated in accordance with the provisions of SFAS 123, and (ii) subsequent to October 31, 2005, based on the grant date fair value estimated in accordance with the provisions of SFAS 123(R). In conjunction with the adoption of SFAS 123(R), Ciena changed its method of attributing the value of share-based compensation expense from the accelerated multiple-option approach to the straight-line single-option method. Compensation expense for all share-based awards granted on or prior to October 31, 2005 will continue to be recognized using the accelerated multiple-option approach. Compensation expense for all share-based awards subsequent to October 31, 2005 is recognized using the straight-line single-option method.

Because share-based compensation expense is based on awards that are ultimately expected to vest, share-based compensation expense has been reduced to account for estimated forfeitures. SFAS 123(R) requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. In Ciena’s pro forma information required under SFAS 123 for periods prior to fiscal 2006, Ciena accounted for forfeitures as they occurred.
     To calculate option-based compensation under SFAS 123(R), Ciena uses the Black-Scholes option-pricing model, which it had previously used for valuation of option-based awards for its pro forma information required under SFAS 123 for periods prior to fiscal 2006. For additional information see Note 14. Ciena’s determination of fair value of option-based awards on the date of grant using the Black-Scholes model is affected by Ciena’s stock price as well as assumptions regarding a number of subjective variables. These variables include, but are not limited to Ciena’s expected stock price volatility over the term of the awards, and actual and projected employee stock option exercise behaviors.
     No tax benefits were attributed to the share-based compensation expense because a valuation allowance was maintained for all net deferred tax assets.
Income Taxes
     Ciena accounts for income taxes in accordance with SFAS 109, “Accounting for Income Taxes.” SFAS 109 describes an asset and liability approach that requires the recognition of deferred tax assets and liabilities for the expected future tax consequences attributable to differences between the carrying amounts of assets and liabilities for financial reporting purposes and their respective tax bases, and for operating loss and tax credit carry forwards. In estimating future tax consequences, SFAS 109 generally considers all expected future events other than the enactment of changes in tax laws or rates. Valuation allowances are provided, if, based upon the weight of the available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized.
Fair Value of Financial Instruments
     The carrying amounts of Ciena’s financial instruments, which include short-term and long-term investments, accounts receivable, accounts payable, and other accrued expenses, approximate their fair values due to their short maturities.
     As of the last day of the second quarter of fiscal 2006, the fair value of the $542.3 million in aggregate principal amount of 3.75% Convertible Notes, due February 1, 2008, was $523.3 million, based on the quoted market price for the notes.
     As of the last day of the second quarter of fiscal 2006, the fair value of the $300.0 million in aggregate principal amount of 0.25% Convertible Senior Notes, due May 1, 2013, was $264.4 million, based on the quoted market price for the notes.
Foreign Currency Translation
     Some of Ciena’s foreign branch offices and subsidiaries use the U.S. dollar as their functional currency, because Ciena, as the U.S. parent entity, exclusively funds the operations of these branch offices and subsidiaries with U.S. dollars. For those subsidiaries using the local currency as their functional currency, assets and liabilities are translated at exchange rates in effect at the balance sheet date. Resulting translation adjustments are recorded directly to a separate component of stockholders’ equity. Where the U.S. dollar is the functional currency, translation adjustments are recorded in other income. The net gain (loss) on foreign currency re-measurement and exchange rate changes for the first six months of fiscal 2005 and the first six months of fiscal 2006 was immaterial for separate financial statement presentation.
Computation of Basic Net Income (Loss) per Common Share and Diluted Net Income (Loss) per Common and Dilutive Potential Common Share
     Ciena calculates earnings per share in accordance with the SFAS 128, “Earnings per Share.” This statement requires dual presentation of basic and diluted EPS on the face of the income statement for entities with a complex capital structure and requires a reconciliation of the numerator and denominator used for the basic and diluted EPS computations.

Software Development Costs
     SFAS 86, “Accounting for the Costs of Computer Software to be Sold, Leased or Otherwise Marketed,” requires the capitalization of certain software development costs incurred subsequent to the date technological feasibility is established and prior to the date the product is generally available for sale. The capitalized cost is then amortized over the estimated product life. Ciena defines technological feasibility as being attained at the time a working model is completed. To date, the period between achieving technological feasibility and the general availability of such software has been short, and software development costs qualifying for capitalization have been insignificant. Accordingly, Ciena has not capitalized any software development costs.
Segment Reporting
     SFAS 131, “Disclosures about Segments of an Enterprise and Related Information,” establishes annual and interim reporting standards for operating segments of a company. It also requires entity-wide disclosures about the products and services an entity provides, the material countries in which it holds assets and reports revenue, and its major customers. Ciena organizes its operations into four separate business segments: the Transport and Switching Group (TSG), the Data Networking Group (DNG), the Broadband Access Group (BBG) and Global Network Services (GNS).
     Revenue from sales to customers outside of the United States is reflected as International in Ciena’s geographic segment distribution of revenue.
Reclassification
     Certain prior year amounts have been reclassified to conform to current year consolidated financial statement presentation.
(3) RESTRUCTURING COSTS
     Ciena has previously taken actions to align its workforce, facilities and operating costs with business opportunities. Ciena historically has committed to a restructuring plan and has incurred the associated liability concurrently in accordance with the provisions of SFAS 146.

(5) ACCOUNTS RECEIVABLE
     As of April 30, 2006, trade accounts receivable, net of allowance for doubtful accounts, included three customers who accounted for 13.0%, 13.8%, and 19.7% of net trade accounts receivable, respectively. As of October 31, 2005, trade accounts receivable, net of allowance for doubtful accounts, included three customers who accounted for 12.1%, 13.1% and 13.8% of net trade accounts receivable, respectively.
     Ciena performs ongoing credit evaluations of its customers and generally has not required collateral or other forms of security from its customers. Ciena maintains an allowance for potential losses associated with accounts that it deems doubtful on a specific identification basis. In determining the appropriate balance for Ciena’s allowance for doubtful accounts, management considers each individual customer account receivable in order to determine collectibility. In doing so, management considers creditworthiness, payment history, account activity and communication with such customer. If a customer’s financial condition changes, Ciena may be required to take a charge for an allowance on doubtful accounts. Ciena’s allowance for doubtful accounts as of October 31, 2005 and April 30, 2006 was $3.3 million and $0.3 million, respectively. During the first six months of fiscal 2006, Ciena recorded the recovery of doubtful accounts in the amount of $2.9 million as a result of payments of amounts due from customers from whom payment was previously deemed doubtful due to the customers’ financial condition. In addition, during the second quarter of fiscal 2006, Ciena wrote-off $0.1 million of doubtful accounts.

(11) CONVERTIBLE NOTES PAYABLE
3.75% Convertible Notes, due February 1, 2008
     On February 9, 2001, Ciena completed a public offering of 3.75% Convertible Notes, due February 1, 2008, in an aggregate principal amount of $690.0 million. Interest is payable on February 1st and August 1st of each year. At the election of the holder, the notes may be converted into shares of Ciena’s common stock at any time before their maturity or their prior redemption or repurchase by Ciena. The conversion rate is 9.5808 shares per each $1,000 principal amount, subject to adjustment in certain circumstances. Ciena has the option to redeem all or a portion of the notes that have not been previously converted at the following redemption prices (expressed as percentage of principal amount):
         
    Redemption  
Period   Price  
Beginning on February 1, 2006 and ending on January 31, 2007
    101.071 %
Beginning on February 1, 2007 and ending on January 31, 2008
    100.536 %
     During the first six months of fiscal 2006, Ciena repurchased $106.5 million of the outstanding 3.75% convertible notes for $98.4 million in open market transactions. Ciena recorded a gain on the extinguishment of debt in the amount of $7.1 million, which consists of the $8.1 million gain from the repurchase of the notes, less $1.0 million of associated debt issuance costs.
     As of the last day of the second quarter of fiscal 2006, the fair value of the $542.3 million in aggregate principal amount of 3.75% convertible notes outstanding was $523.3 million, based on the quoted market price for the notes.
0.25% Convertible Senior Notes due May 1, 2013
     On April 10, 2006, Ciena completed a public offering of 0.25% Convertible Senior Notes due May 1, 2013, in aggregate principal amount of $300.0 million. The notes bear interest at the annual rate of 0.25% from April 10, 2006, payable semi-annually on May 1 and November 1, commencing on November 1, 2006. The notes are senior

14


 

unsecured obligations of Ciena and rank equally with all of Ciena’s other existing and future senior unsecured debt.
     At the election of the holder, the notes may be converted prior to maturity into shares of Ciena common stock at the initial conversion rate of 177.1009 shares per $1,000 in principal amount, which is equivalent to an initial conversion price of $5.6465 per share. The notes may not be redeemed by Ciena prior to May 5, 2009. At any time on or after May 5, 2009, if the closing sale price of Ciena’s common stock for at least 20 trading days in any 30 consecutive trading day period ending on the date one day prior to the date of the notice of redemption exceeds 130% of the conversion price, Ciena may redeem the notes in whole or in part, at a redemption price in cash equal to the principal amount to be redeemed, plus accrued and unpaid interest.
     If Ciena undergoes a “fundamental change” (as that term is defined in the indenture), holders of notes will have the right, subject to certain exemptions, to require Ciena to purchase for cash any or all of their notes at a price equal to the principal amount, plus accrued and unpaid interest. If the holder elects to convert his or her notes in connection with a specified fundamental change, in certain circumstances, Ciena will be required to increase the applicable conversion rate, depending on the price paid per share for Ciena common stock and the effective date of the fundamental change transaction.
     As of the last day of the second quarter of fiscal 2006, the fair value of the $300.0 million in aggregate principal amount of 0.25% convertible senior notes outstanding was $264.4 million, based on the quoted market price for the notes.
(12) LOSS PER SHARE CALCULATION
     Basic and diluted EPS are computed using the weighted average number of common shares outstanding (excluding restricted stock subject to repurchase). Because of the anti-dilutive effect, diluted EPS and the weighted average number of common shares do not include shares underlying: stock options, warrants, restricted stock, restricted stock units, Ciena’s 3.75% convertible notes and 0.25% convertible senior notes. Shares underlying these securities totaled approximately 60.1 million and 54.2 million for the second quarter of fiscal 2005 and the second quarter of fiscal 2006, respectively and approximately 55.0 million and 52.3 million for the first six months of fiscal 2005 and the first six months of fiscal 2006, respectively.
(13) STOCKHOLDERS’ EQUITY
     Concurrent with Ciena’s April 10, 2006 issuance of 0.25% Convertible Senior Notes due May 1, 2013, Ciena purchased a call spread option on its common stock from an affiliate of the underwriter. The call spread option is designed to mitigate dilution from the conversion of the notes to the extent that the market price per share of Ciena common stock upon exercise is greater than the conversion price, subject to a cap.
     The call spread option covers approximately 53.1 million shares of Ciena common stock, which is the number of shares issuable upon conversion of the notes in full. The call spread option has a “lower strike price” of $5.6465 and a “higher strike price” of $6.50575 and is exercisable and expires on May 1, 2013, the maturity date of the notes. Ciena can exercise the call spread option on a net cash basis, a net share basis or a full physical settlement. A net cash settlement would result in Ciena receiving an amount ranging from $0, if the market price per share of Ciena common stock upon exercise is equal to or below the lower strike price, to approximately $45.7 million, if the market price per share of Ciena common stock upon exercise is at or above the higher strike price. Settlement of the call spread option on a net share basis would result in Ciena receiving between 0 shares, if the market price per share of Ciena common stock upon exercise is equal to or below the lower strike price, up to approximately 7.0 million shares, if the market price per share of Ciena common stock upon exercise is equal to the higher strike price. The value of the consideration of a net share settlement will be equal to the value upon a net cash settlement. If the market price is between the lower strike price and the higher strike price, in lieu of a net share or net cash settlement, Ciena may elect to receive the full number of shares underlying the call spread option upon payment by Ciena of an aggregate option exercise price of $300.0 million. Should there be an early unwind of the call spread option, the amount of cash or net shares to be received by Ciena will be dependent upon the existing overall market conditions, and on Ciena’s stock price, the volatility of Ciena’s stock and the remaining term of the call spread option.
     The number of shares subject to the call spread option and the lower price and higher strike prices are subject to customary adjustments. The $28.5 million cost of the call spread option was recorded as a reduction in additional paid in capital.

     During fiscal 2005, the Board of Directors determined that all future grants of stock options, restricted stock units, or other forms of equity-based compensation will solely be issued under the Ciena Corporation 2000 Equity Incentive Plan (the “2000 Plan”) and the 2003 Employee Stock Purchase Plan (the “ESPP”).
Ciena Corporation 2000 Equity Incentive Plan
     The 2000 Plan, which is a shareholder approved plan, was assumed by Ciena as a result of its merger with ONI. It authorizes the issuance of stock options, restricted stock, restricted stock units and stock bonuses to employees, officers, directors, consultants, independent contractors and advisors. The Board of Directors or its Compensation Committee has broad discretion to establish the terms and conditions for grants, including number of shares, vesting and required service or other performance criteria. The maximum term of any award under the 2000 Plan is ten years. The exercise price of options may not be less than 85% of the fair market value of the stock at the date of grant, or 100% of the fair market value for qualified options.
     Under the terms of the 2000 Plan, the number of shares authorized for issuance will increase by 5.0% of the number of issued and outstanding shares of Ciena each January 1st, unless the Compensation Committee reduces the amount of the increase in any year. By action of the Compensation Committee, the plan increased by (i) zero shares on January 1, 2006, (ii) zero shares on January 1, 2005, and (iii) 9.5 million shares, or 2.0% of the then issued and outstanding shares of Ciena, on January 1, 2004. In addition, any shares subject to outstanding options or other awards under the ONI 1997 Stock Plan, ONI 1998 Equity Incentive Plan, or ONI 1999 Equity Incentive Plan that are forfeited upon cancellation of the award are available for grant and issuance under the 2000 Plan. As of April 30, 2006, there were 39.2 million shares authorized and available to grant under the 2000 Plan.

     As of April 30, 2006, total unrecognized compensation expense related to unvested stock options was $14.6 million. This expense is expected to be recognized over a weighted-average period of 1.6 years.
     On October 26, 2005, Ciena’s Board of Directors accelerated the vesting of approximately 14.1 million unvested, “out-of-the-money” stock options previously awarded to employees, officers and directors under Ciena’s stock option plans. Certain performance-based options held by executives were not subject to this acceleration. For purposes of the acceleration, options with an exercise price greater than $2.49 per share were deemed “out-of-the-money.” The accelerated options, which were considered fully vested as of October 26, 2005, had exercise prices ranging from $2.50 to $46.99 per share and a weighted average exercise price of $4.39 per share. Ciena did not accelerate the vesting of options that had an exercise price per share of $2.49 or less. The primary purpose of the accelerated vesting was to enable Ciena to avoid recognizing future compensation expense associated with these out-of-the-money stock options upon adoption of SFAS 123(R) for fiscal 2006.
     Restricted Stock Units
     A restricted stock unit is a right to receive a share of Ciena common stock when the unit vests. Ciena calculates the fair value of each restricted stock unit using the intrinsic value method and recognizes the expense straight-line over the requisite period. The following table is a summary of Ciena’s restricted stock unit activity for the first six months of fiscal 2006, based on Ciena’s closing stock price on April 28, 2006 of $4.09 per share (shares and intrinsic value in thousands):

     The total intrinsic value of restricted stock units converted in the first six months of fiscal 2006 was $0.6 million.
     As of April 30, 2006, total unrecognized compensation expense related to restricted stock units was $3.3 million. This expense is expected to be recognized over a weighted-average period of 1.5 years.
2003 Employee Stock Purchase Plan
     In March 2003, Ciena shareholders approved the ESPP, which authorized the issuance of 20.0 million shares. Under the ESPP, eligible employees may enroll in a 24-month offer period during certain open enrollment periods.

17


 

New offer periods begin March 16 and September 16 of each year. Each offer period consists of four, six-month purchase periods during which employee payroll deductions are accumulated. These deduction amounts, which are subject to certain limitations, are accumulated, and, at the end of each purchase period, are used to purchase shares of common stock. The purchase price of the shares is 15% less than the fair market value on either the first day of an offer period or the last day of a purchase period, whichever is lower. If the fair market value on the purchase date is less than the fair market value on the first day of an offer period, then participants automatically commence a new 24-month offer period. The ESPP has a ten-year term.
     At the 2005 annual meeting, Ciena shareholders approved an amendment to the ESPP pursuant to which 11.8 million shares were added to the ESPP on March 16, 2005, increasing the number of shares available under the ESPP to 25.0 million. The amendment to the ESPP also provided for an “evergreen” provision, pursuant to which, beginning on December 31, 2005, the number of shares available for issuance under the ESPP annually increases by up to four million shares, provided that the total number of shares available for issuance at any time under the ESPP shall not exceed 25.0 million. Pursuant to the evergreen provision, the maximum number of shares that may be added to the ESPP during the remainder of its ten-year term is 28.0 million. On December 31, 2005, the evergreen provision automatically added an additional 2.1 million shares to the ESPP, increasing the total number of shares available to 25.0 million. On March 15, 2006, 2.3 million shares were issued under the plan for $3.9 million. As of April 30, 2006, 22.7 million shares are available to grant under this plan.

Share-Based Compensation under SFAS 123(R) for Fiscal 2006 and APB 25 for Fiscal 2005
     On November 1, 2005, Ciena adopted SFAS 123(R), which requires the measurement and recognition of compensation expense, based on estimated fair values, for all share-based payments awards made to Ciena’s employees and directors including stock options, restricted stock, restricted stock unit awards and stock purchased under Ciena’s ESPP.
     Prior to the adoption of SFAS 123(R), Ciena accounted for share-based awards to employees and directors using the intrinsic value method in accordance with APB 25, as interpreted by FASB Interpretation (FIN) No. 44, “Accounting for Certain Transactions Involving Stock Compensation, an Interpretation of APB Opinion No. 25,” as allowed under SFAS 123, “Accounting for Stock-Based Compensation.” Share-based compensation expense of $3.5 million for the second quarter of fiscal 2005 and $5.5 million for the first six months of fiscal 2005 was solely related to share-based awards assumed through acquisitions and restricted stock unit awards that Ciena had been recognizing in its consolidated statement of operations in accordance with the provisions set forth above. Because the exercise price of Ciena’s stock options granted to employees and directors equaled the fair market value of the underlying stock at the grant date, under the intrinsic value method, no share-based compensation expense was otherwise recognized in Ciena’s consolidated statement of operations.
     The following table summarizes share-based compensation expense under SFAS 123(R) for the quarter and six months ended April 30, 2006; and share-based compensation expense under APB 25, as interpreted by FIN 44 for the quarter and six months ended April 30, 2005, which was allocated as follows (in thousands):

Fair Value and Assumptions Used to Calculate Fair Value under SFAS 123(R) and SFAS 123
     Assumptions for Option-Based Awards under SFAS 123(R)
     The fair value of each option award is estimated on the date of grant using the Black-Scholes Option Pricing Model, with the following weighted average assumptions for the second quarter of fiscal 2005 and the second quarter of fiscal 2006:
                     
    Quarter Ended April 30,   Six Months Ended April 30,
    2005     2006   2005   2006
Expected volatility
    67 %   61.5%   65.8% - 66.7%   61.5%
Risk-free interest rate
    3.9 %   4.6% - 5.0%   3.7% - 3.9%   4.3% - 5.0%
Expected life (years)
    4.5     5.5 - 6.1   4.5   5.5 - 6.1
Expected dividend yield
    0.0 %   0.0%   0.0%   0.0%
     Consistent with SFAS 123(R) and SAB 107, Ciena considered the implied volatility and historical volatility of its stock price in determining its expected volatility, and, finding both to be equally reliable, determined that a combination of both would result in the best estimate of expected volatility.

19


 

     The risk-free interest rate assumption is based upon observed interest rates appropriate for the term of Ciena’s employee stock options.
     The expected life of employee stock options represents the weighted-average period the stock options are expected to remain outstanding. Because Ciena considers its options to be “plain vanilla,” it calculated the expected term using the simplified method as prescribed in SAB 107. Under SAB 107, options are considered to be “plain vanilla” if they have the following basic characteristics: granted “at-the-money”; exerciseability is conditioned upon service through the vesting date; termination of service prior to vesting results in forfeiture; limited exercise period following termination of service; options are non-transferable and non-hedgeable.
     The dividend yield assumption is based on Ciena’s history and expectation of dividend payouts.
     As share-based compensation expense recognized in the consolidated statement of operations for the second quarter of fiscal 2006 is based on awards ultimately expected to vest, it has been reduced for estimated forfeitures. Forfeitures were estimated based on Ciena’s historical experience.
     Assumptions for option-based awards under SFAS 123
     Prior to the first quarter of fiscal 2006, Ciena considered the implied volatility and historical volatility of its stock price in determining its expected volatility. The risk-free interest rate was based upon assumption of interest rates appropriate for the term of Ciena’s employee stock options. The dividend yield assumption was based on Ciena’s history and expectation of dividend payouts. Forfeitures prior to the first quarter of fiscal 2006 were accounted for as they occurred.
     Assumptions for Restricted Stock Unit Awards under SFAS 123(R)
     The fair value of each restricted stock unit award is estimated on the date of grant using the intrinsic value method. The weighted average fair value of each restricted stock unit granted under Ciena’s stock option plans for the three months and six months ended April 30, 2006 was $4.47 and $2.59, respectively. There were no restricted stock units issued in the first six months of fiscal 2005.
     Assumptions for Employee Stock Purchase Plan Awards under SFAS 123(R)
     The fair value of each ESPP award is initially determined at the grant date using the graded vesting approach. Under the graded vesting approach, Ciena’s ESPP, which has a 24-month offer period consisting of four, six-month purchase periods, is treated for valuation purpose as four separate option tranches, each commencing on the initial grant date. As a result, a standard offer period consists of four option tranches with individual lives of six, 12, 18 and 24 months. Each tranche is then expensed straight-line over its individual life.

(17) CONTINGENCIES
Litigation
     On October 3, 2000, Stanford University and Litton Systems filed a complaint in the United States District Court for the Central District of California against Ciena and several other defendants, alleging that optical fiber amplifiers incorporated into certain of those parties’ products infringe U.S. Patent No. 4,859,016 (the “‘016 Patent”). The complaint seeks injunctive relief, royalties and damages. On October 10, 2003, the court stayed the case pending final resolution of matters before the U.S. Patent and Trademark Office (the “PTO”), including a request for and disposition of a reexamination of the ‘016 Patent. On October 16, 2003 and November 2, 2004, the PTO granted reexaminations of the ‘016 Patent, resulting in a continuation of the stay of the case. On July 11, 2005, the PTO issued a Notice of Intent to Issue a Reexamination Certificate and a Statement of Reasons for Patentability/Confirmation, stating its intent to confirm all claims of ‘016 Patent. As a result, on October 10, 2005, Litton Systems filed a motion with the district court for an order lifting the stay of the case, and defendant Pirelli S.p.A. filed with the PTO a new request for ex parte reexamination of the ‘016 Patent. On December 15, 2005, the PTO denied Pirelli’s request for reexamination. On December 19, 2005, the district court denied Litton Systems’ motion to lift the stay. On January 17, 2006, Pirelli filed a petition for reconsideration of the order denying its request for reexamination. On March 6, 2006, the PTO vacated its Notice of Intent to Issue Reexamination Certificate as premature, reassigned the case to a new examiner for further proceedings, and dismissed as moot Pirelli’s petition for reconsideration. Ciena believes that it has valid defenses to the lawsuit and intends to defend it vigorously in the event the stay of the case is lifted.
     As a result of its merger with ONI Systems Corp. in June 2002, Ciena became a defendant in a securities class action lawsuit. Beginning in August 2001, a number of substantially identical class action complaints alleging violations of the federal securities laws were filed in the United States District Court for the Southern District of New York. These complaints name ONI, Hugh C. Martin, ONI’s former chairman, president and chief executive officer; Chris A. Davis, ONI’s former executive vice president, chief financial officer and administrative officer; and certain underwriters of ONI’s initial public offering as defendants. The complaints were consolidated into a single action, and a consolidated amended complaint was filed on April 24, 2002. The amended complaint alleges, among other things, that the underwriter defendants violated the securities laws by failing to disclose alleged compensation arrangements (such as undisclosed commissions or stock stabilization practices) in the initial public offering’s registration statement and by engaging in manipulative practices to artificially inflate the price of ONI’s common stock after the initial public offering. The amended complaint also alleges that ONI and the named former officers

22


 

violated the securities laws on the basis of an alleged failure to disclose the underwriters’ alleged compensation arrangements and manipulative practices. No specific amount of damages has been claimed. Similar complaints have been filed against more than 300 other issuers that have had initial public offerings since 1998, and all of these actions have been included in a single coordinated proceeding. Mr. Martin and Ms. Davis have been dismissed from the action without prejudice pursuant to a tolling agreement. In July 2004, following mediated settlement negotiations, the plaintiffs, the issuer defendants (including Ciena), and their insurers entered into a settlement agreement, whereby the plaintiffs’ cases against the issuers are to be dismissed. The plaintiffs and issuer defendants subsequently moved the court for preliminary approval of the settlement agreement, which motion was opposed by the underwriter defendants. On February 15, 2005, the district court granted the motion for preliminary approval of the settlement agreement, subject to certain modifications to the proposed bar order, and directed the parties to submit a revised settlement agreement reflecting its opinion. On August 31, 2005, the district court issued a preliminary order approving the stipulated settlement agreement, approving and setting dates for notice of the settlement to all class members. A fairness hearing was held on April 24, 2006, at which time the court took the matter under advisement. If the court determines that the settlement is fair to the class members, the settlement will be approved. The settlement agreement does not require Ciena to pay any amount toward the settlement or to make any other payments.
     On January 18, 2005, Ciena filed a complaint in the United States District Court for the Eastern District of Texas, Marshall Division against Nortel Networks, Inc., Nortel Networks Corporation and Nortel Networks Limited (collectively, “Nortel”), which complaint was subsequently amended. Ciena’s amended complaint charges Nortel with infringement of nine patents related to Ciena’s communications networking systems and technology. Ciena seeks to enjoin Nortel’s infringing activities and recover damages caused by such infringement. On March 14, 2005, Nortel filed an answer to Ciena’s complaint and a counterclaim against Ciena, each of which have subsequently been amended. Nortel’s amended counterclaim charges Ciena with infringement of 13 patents related to Nortel’s communications networking systems and technology, including certain of Nortel’s SONET, ATM and VLAN systems and technology. Nortel’s counterclaim seeks injunctive relief and damages. The court ordered that the case be tried in stages, and that 12 of the 22 total patents in suit (five for Ciena and seven for Nortel) would be at issue in stage one. At the same time, the court stayed all claims relating to the remaining patents. A Markman hearing was held in November 2005 and, on April 25, 2006, the court issued a memorandum opinion construing, or electing not to construe, certain disputed claims relating to the “stage one” patents. Each of the parties has subsequently filed several motions for summary judgment or partial summary judgment on certain of the “stage one” patents, to which oppositions and replies have also been filed. On May 8, 2006, the court granted the parties’ joint request for a continuance of the trial on the “stage one” patents, which is now scheduled for July 2006.
     On April 17, 2006, Nortel filed a new complaint in the United States District Court for the District of Texas, Marshall Division, charging Ciena with infringement of six additional patents related to Nortel’s communications networking systems and technology. Ciena intends to vigorously defend against the suit and to file a counterclaim against Nortel, charging Nortel with infringement of certain additional patents related to Ciena’s communications networking systems and technology.
     In addition to the matters described above, Ciena is subject to various legal proceedings, claims and litigation arising in the ordinary course of business. While the outcome of these matters is currently not determinable, Ciena does not expect that the ultimate costs to resolve these matters will have a material effect on its results of operations, financial position or cash flows.
Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations
     Some of the statements contained, or incorporated by reference, in this quarterly report discuss future events or expectations, contain projections of results of operations or financial condition, changes in the markets for our products and services, or state other “forward-looking” information. Ciena’s “forward-looking” information is based on various factors and was derived using numerous assumptions. In some cases, you can identify these “forward-looking statements” by words like “may,” “will,” “should,” “expects,” “plans,” “anticipates,” “believes,” “estimates,” “predicts,” “potential” or “continue” or the negative of those words and other comparable words. You should be aware that these statements only reflect our current predictions and beliefs. These statements are subject to known and unknown risks, uncertainties and other factors, and actual events or results may differ materially. Important factors that could cause our actual results to be materially different from the forward-looking statements are disclosed throughout this report, particularly under the heading “Risk Factors” in Item 1A of Part II of this report below. You should review these risk factors and the rest of this quarterly report in combination with the more detailed description of our business in our annual report on Form 10-K, which we filed with the Securities and Exchange Commission on January 12, 2006, for a more complete understanding of the risks associated with an investment in Ciena’s securities. Ciena undertakes no obligation to revise or update any forward-looking statements.

Overview
     Ciena Corporation supplies communications networking equipment, software and services to telecommunications service providers, cable operators, governments and enterprises. Our product and service offerings enable customers to converge, transition and connect communications networks that deliver voice, video and data services. We are a network specialist, focused on optimizing access and edge networks for broadband communication, enhancing enterprise data services and evolving network infrastructures to support new, high-bandwidth applications and network convergence. Our equipment, software and services enable customers to gain a competitive advantage by increasing the functionality of their networks and reducing their total costs of ownership for delivering voice, video and data services.
     Our revenue increased to $131.2 million in the second quarter of fiscal 2006, representing a 26.3% increase from $103.8 million in the second quarter of fiscal 2005 and an 8.9% increase from $120.4 million in the first quarter of fiscal 2006. Revenue increased sequentially from the first quarter of fiscal 2006 primarily due to increased sales of core switching products, our CN 4200™ FlexSelect™ Advanced Services Platform and data networking products. Our second quarter results include initial revenue associated with our selection as a preferred supplier for the optical transmission portion of BT’s 21st Century Network (21CN). Revenue from BT, including that from non 21CN-related deployments, represented less than 10% of total revenues during the second quarter of fiscal 2006.
     Revenue growth continues to be driven, in substantial part, by increased investments by our customers in network infrastructure to address capacity needs, the transition to next-generation networks and broader services mix.
     During the second quarter of fiscal 2006, three customers represented 41.5% of revenue, and for the first six months of fiscal 2006, four customers represented 49.8%. We expect that our business will continue to be affected by mergers of some of our largest customers. We believe that the mergers between Verizon and MCI and between AT&T and SBC have not had a negative effect on our business to date. Mergers among major telecommunications carriers have, however, also increased concentration of our customers. During the second fiscal quarter, AT&T announced its plans to acquire BellSouth, which has been a significant Ciena customer during prior periods. Over the long term, increased merger activity involving our customers may result in additional risks to our business, including increased pricing pressure, changes in network strategy or cost reduction efforts affecting network investments.
     We expect further revenue growth and improvement in our financial results during the remainder of fiscal 2006. Some of this expected revenue growth will come from orders related to larger network builds, which occur in phases. The timing and size of these orders, our ability to deliver products against them, and the timing of satisfaction of acceptance criteria will all contribute to fluctuations in our revenues from quarter to quarter.
      Gross margin increased to 48.0% in the second quarter of fiscal 2006 and 45.1% for the first six months of fiscal 2006. Gross margin for the second quarter of fiscal 2006 increased from 26.2% in the second quarter of fiscal 2005 and 41.9% for the first quarter of fiscal 2006. The substantial increase in gross margin during the second quarter of fiscal 2006 reflects our continued efforts to reduce our product-related costs in recent quarters and a favorable mix of higher margin products, including increased revenue from channel line cards for our CoreStream® Agility Optical Transport System and our CoreDirector® Multiservice Optical Switch. While we have experienced significant gross margin improvement in recent quarters, gross margin remains susceptible to fluctuation from period to period. Our gross margin can be significantly affected by product mix, customer mix, the effect of our product-related cost reductions, sales volume and the level of pricing pressure that we experience. Maintaining gross margin at the level achieved in the first six months of fiscal 2006 will be increasingly important in upcoming fiscal quarters as we seek to achieve and maintain profitability.
     Operating expense was $70.2 million in the second quarter of fiscal 2006, an increase from $65.6 million in the first quarter of fiscal 2006 and a decrease from $94.1 million in the second quarter of fiscal 2005. Operating expense increased sequentially from the first quarter of 2006, in part, due to an increase in legal expenses associated with our pending litigation with Nortel Networks and an increase in restructuring charges. In addition, our operating expense for the first quarter of 2006 reflected a $2.6 million recovery of doubtful accounts. Increased restructuring charges during the second quarter of fiscal 2006 reflect the closure of our Shrewsbury, NJ facility and severance, relocation and other employee costs for the related headcount reduction of 86 employees, primarily in research in development. During the second quarter of fiscal 2006, we formally opened our new research and development center in Gurgaon, India. At April 30, 2006, we had approximately 40 employees located at this facility. This research and development center is expected to grow to include as many as 300 product development engineers in the next 18 months to two years. We believe this research and development center will enable us to capitalize on the strong engineering resources in the region.

     On April 10, 2006, we completed a $300.0 million public offering of 0.25% Convertible Senior Notes due May 1, 2013, resulting in net proceeds to us of $263.9 million after deducting underwriting discounts, expenses and $28.5 million used to purchase a call spread option on our common stock. The call spread option is intended to reduce the potential dilution from conversion of the 0.25% convertible senior notes. For additional information on the terms of these notes and the call spread option, you should review Note 11 to the Consolidated Financial Statements under Item 1 of Part I of this report. We expect to use the net proceeds for general corporate purposes, which may include repurchases of our outstanding 3.75% Convertible Notes due February 1, 2008. At April 30, 2006, the remaining principal balance on our outstanding 3.75% convertible notes was $542.3 million.
     As of April 30, 2006, headcount was 1,388, down from 1,442 at January 31, 2006 and 1,497 at the end of fiscal 2005.

Revenue
    Product revenue increased from the second quarter of fiscal 2005 to the second quarter of fiscal 2006, due to increased sales across all business segments. The largest increase in sales was related to our transport and switching products followed by increased sales of our data networking products.
 
    Service revenue increased from the second quarter of fiscal 2005 to the second quarter of fiscal 2006, primarily due to increases in maintenance and support services, deployment services and product training services.
 
    United States revenue increased from the second quarter of fiscal 2005 to the second quarter of fiscal 2006, primarily due to increased sales of our data networking products and sales of our broadband access systems.
 
    International revenue increased from the second quarter of fiscal 2005 to the second quarter of fiscal 2006, primarily due to increased sales of our transport and switching products.

Gross profit
    Gross profit as a percentage of revenue increased from the second quarter of fiscal 2005 to the second quarter of fiscal 2006 largely due to increased sales volume, sales of higher margin products and product cost improvements resulting from our efforts to employ a global approach to sourcing components and manufacturing our products.
 
    Gross profit on products as a percentage of product revenue increased from the second quarter of fiscal 2005 to the second quarter of fiscal 2006, primarily due to cost reductions and higher margin product mix.
 
    Gross profit on services as a percentage of services revenue increased from the second quarter of fiscal 2005 to the second quarter of fiscal 2006, primarily due to the effect of service rate stability in connection with our deployment services and reduced service overhead and deployment costs.

*   Denotes % of total revenue
 
**   Denotes % change from 2005 to 2006
    Research and development expense decreased from the second quarter of fiscal 2005 to the second quarter of fiscal 2006, primarily due to reductions of $4.6 million in employee compensation, $1.5 million in depreciation expense, and $0.7 million in prototype. The reduction in employee compensation was driven by headcount reductions, partially offset by an increase of $0.6 million in share-based compensation expense due to the application of SFAS 123(R).
 
    Selling and marketing expense decreased from the second quarter of fiscal 2005 to the second quarter of fiscal 2006 due to reductions of $1.4 million in depreciation costs, $0.8 million in temporary import costs, $0.4 million in travel and $0.4 million in information systems expense, offset by an increase of $0.6 million in demonstration equipment costs. Employee compensation remained relatively flat due to an increase of $1.5 million in salaries and commissions offset by a reduction of $1.5 million in share-based compensation expense due to the application of SFAS 123(R).
 
    General and administrative expense increased from the second quarter of fiscal 2005 to the second quarter of fiscal 2006 primarily due to an increase of $1.8 million in legal expenses, primarily associated with our pending patent litigation with Nortel Networks, and an increase of $0.9 million in employee compensation. The increase in employee compensation included an increase of $0.8 million in share-based compensation expense due to the application of SFAS 123(R).
 
    Amortization of intangible assets costs decreased from the second quarter of fiscal 2005 to the second quarter of fiscal 2006 due to the write-off of intangible assets recorded in the fourth quarter of fiscal 2005.
 
    Restructuring costs incurred during the second quarter of 2006 were related to a work force reduction of approximately 86 employees and the closure of a facility located in Shrewsbury, NJ. These actions were taken as part of our continuing efforts to reduce expense.
 
    Recovery of doubtful accounts, net for the second quarter of fiscal 2006 was related to the payment of amounts due from customers from whom payment was previously deemed doubtful due to the customers’ financial condition.
 
    Gain on lease settlement for the second quarter of fiscal 2006 was related to the termination of our obligations under the lease for our former Cupertino, CA facility.

    Interest and other income, net increased from the second quarter of fiscal 2005 to the second quarter of fiscal 2006 due to the impact of higher interest rates.
 
    Interest expense decreased from the second quarter of 2005 to the second quarter of 2006 due to the repurchase of some of our 3.75% convertible notes during fiscal 2005 and the first quarter of fiscal 2006.
 
    Provision for income taxes for the second quarter of fiscal 2005 and the second quarter of fiscal 2006 was primarily attributable to foreign tax related to Ciena’s foreign operations.

    Amortization of intangible assets costs decreased from the first six months of fiscal 2005 to the first six months of fiscal 2006 due to the write-off of intangible assets recorded in the fourth quarter of fiscal 2005.
 
    Restructuring costs incurred during the first six months of fiscal 2006 were related to a work force reduction of approximately 148 employees and the closure of one of our facilities located in Kanata, Ontario and our facility in Shrewsbury, NJ. These actions were taken as part of our continuing efforts to reduce expense.
 
    Recovery of doubtful accounts, net for the first six months of fiscal 2006 was related to the payment of amounts due from customers from whom payment was previously deemed doubtful due to the customers’ financial condition.

    Interest and other income, net increased from the first six months of fiscal 2005 to the first six months of fiscal 2006 due to the impact of higher interest rates.
 
    Interest expense decreased from the first six months of fiscal 2005 to the first six months of fiscal 2006 due to the repurchase of some of our 3.75% convertible notes during fiscal 2005 and fiscal 2006.
 
    Loss on equity investments for the first six months of fiscal 2005 and the first six months of fiscal 2006 was due to a decline in the value of our investments in privately held technology companies that was determined to be other than temporary.
 
    Gain on extinguishment of debt for the first six months of fiscal 2006 resulted from our repurchase of $106.5 million of our outstanding 3.75% convertible notes in open market transactions for $98.4 million. We recorded a gain on the extinguishment of debt in the amount of $7.1 million, which consists of the $8.1 million gain from the repurchase of the notes, less $1.0 million of associated debt issuance costs.
 
    Provision for income taxes for the first six months of fiscal 2005 and the first six months of fiscal 2006 was primarily attributable to foreign tax related to Ciena’s foreign operations. We did not record a tax benefit for domestic losses during either period. We will continue to maintain a valuation allowance against certain deferred tax assets until sufficient evidence exists to support its reversal.

Liquidity and Capital Resources
     At April 30, 2006, our principal source of liquidity was cash and cash equivalents, short-term investments and long-term investments. The following table summarizes our cash and cash equivalents, short-term investments and long-term investments (in thousands):
                         
    October 31,     April 30,     Increase  
    2005     2006     (decrease)

  $ 1,093,487     $ 1,222,730     $ 129,243  
 
                 
     The increase in total cash, cash equivalents and short-term and long-term investments during the first six months of fiscal 2006 was primarily related to our April 10, 2006 issuance of 0.25% Convertible Senior Notes due May 1,

34


 

2013, resulting in proceeds of $263.9 million, net of offering expenses, underwriting discounts and the $28.5 million cost of a call spread option purchased by Ciena. This increase was offset by $98.4 million of cash used for the repurchase of our 3.75% convertible notes. Cash, cash equivalents and short-term and long-term investments at April 30, 2006 also reflect $45.6 million of cash consumed in operating activities during the first six months of fiscal 2006. Based on past performance and current expectations, we believe that our cash and cash equivalents, short-term investments, and cash generated from operations will satisfy our working capital needs, capital expenditures and other liquidity requirements associated with our existing operations through at least the next 12 months.
     The following sections review the significant activities that had an impact on our cash during the first six months of fiscal 2006.
Operating Activities

     Accounts Receivable, Net
     Cash consumed by accounts receivable, net decreased from the first six months of fiscal 2005 to the first six months of fiscal 2006, due to reduced days sales outstanding (“DSO”). Ciena’s DSO’s for six months ending April 30, 2005 and April 30, 2006 were 60 days and 55 days, respectively. The decrease in DSOs was primarily due to our recognition during the second quarter of fiscal 2006 of revenue formerly deferred, for which we had previously received payment. We expect that our accounts receivable, net and DSOs may fluctuate from quarter to quarter in fiscal 2006, but generally will increase during fiscal 2006, due to the size and timing of orders, the timing of satisfaction of contractual acceptance criteria, and extended payment terms particularly related to our international customers.

     Inventory, Net
     Cash consumed by inventory, net increased from the first six months of fiscal 2005 to the first six months of fiscal 2006, primarily due to increased customer demand, and a decrease in inventory turns. Ciena’s inventory turns for the periods ending April 30, 2005 and April 30, 2006 were 5.6 turns per year and 3.0 turns per year, respectively. The decrease was primarily related to increases in finished goods inventory purchased by Ciena based on customer forecasts in advance of orders and finished goods inventory located at customer facilities awaiting contractual acceptance. Our cash consumed by inventory has increased in recent quarters. We expect cash consumed by

inventory will fluctuate from quarter to quarter in fiscal 2006, but generally increase during the remainder of fiscal 2006.

We paid an additional $6.0 million on leases related to restructured facilities and $4.2 million on leases associated with unfavorable lease commitments.

Financing Activities
     Cash provided by financing activities during the first six months of fiscal 2006 was primarily related to a public offering of 0.25% Convertible Senior Notes due May 1, 2013, in aggregate principal amount of $300.0 million that was completed during the second quarter of fiscal 2006. Associated with the offering, we purchased a call spread option on our common stock for $28.5 million and paid debt issuance costs of $7.7 million. During the first six months of fiscal 2006, we also repurchased $106.5 million of our outstanding 3.75% convertible notes, due February 1, 2008, in open market transactions for $98.4 million. We also received $16.2 million from the exercise of employee stock options and employee participation in Ciena’s employee stock purchase plan.

Off-Balance Sheet Arrangements
     Ciena does not engage in any off-balance sheet financing arrangements. In particular, we do not have any interest in so-called limited purpose entities, which include special purpose entities (SPEs) and structured finance entities.
Critical Accounting Policies and Estimates
     The preparation of consolidated financial statements requires Ciena to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. On an ongoing basis, we reevaluate our estimates, including those related to bad debts, inventories, investments, intangible assets, goodwill, income taxes, warranty obligations, restructuring, and contingencies and litigation. Ciena bases its 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.
Revenue Recognition
     Some of our communications networking equipment is integrated with software that is essential to the functionality of the equipment. We provide unspecified software upgrades and enhancements related to the equipment through our maintenance contracts for these products. Accordingly, we account for revenue in accordance with Statement of Position No. 97-2, “Software Revenue Recognition,” and all related interpretations. Revenue is recognized when persuasive evidence of an arrangement exists, delivery has occurred, the fee is fixed or determinable, and collectibility is reasonably assured. In instances where final acceptance of the product is specified by the customer, revenue is deferred until all acceptance criteria have been met. Customer purchase agreements and customer purchase orders are generally used to determine the existence of an arrangement. Shipping documents and customer acceptance, when applicable, are used to verify delivery. We assess whether the fee is fixed or determinable based on the payment terms associated with the transaction and whether the sales price is subject to refund or adjustment. We assess collectibility based primarily on the creditworthiness of the customer as determined by credit

37


 

checks and analysis, as well as the customer’s payment history. When a sale involves multiple elements, such as sales of products that include services, the entire fee from the arrangement is allocated to each respective element based on its relative fair value and recognized when revenue recognition criteria for each element are met. The amount of product and service revenue recognized is affected by our judgments as to whether an arrangement includes multiple elements and, if so, whether vendor-specific objective evidence of fair value exists. Changes to the elements in an arrangement and our ability to establish vendor-specific objective evidence for those elements could affect the timing of revenue recognition. Our total deferred revenue for products was $14.5 million and $28.5 million as of October 31, 2005 and April 30, 2006, respectively. Our service revenue is deferred and recognized ratably over the period during which the services are to be performed. Our total deferred revenue for services was $29.0 million and $30.3 million as of October 31, 2005 and April 30, 2006, respectively.
Share-Based Compensation
     On November 1, 2005, Ciena adopted SFAS 123(R), “Shared-Based Payment,” which requires the measurement and recognition of compensation expense, based on estimated fair values, for all share-based awards, made to employees and directors, including stock options, restricted stock, restricted stock units and participation in Ciena’s employee stock purchase plan. Share-based compensation expense recognized in Ciena’s consolidated statement of operations for the second quarter of fiscal 2006 includes compensation expense for share-based awards granted (i) prior to, but not yet vested as of October 31, 2005, based on the grant date fair value estimated in accordance with the provisions of SFAS 123, and (ii) subsequent to October 31, 2005, based on the grant date fair value estimated in accordance with the provisions of SFAS 123(R).
     We estimate the fair value of stock options granted using the Black-Scholes option pricing method. This option pricing model requires the input of highly subjective assumptions, including the option’s expected life and the price volatility of the underlying stock. The expected life of employee stock options represents the weighted-average period the stock options are expected to remain outstanding. Because Ciena considers its options to be “plain vanilla” we calculate the expected term using the simplified method as prescribed in SAB 107. Under SAB 107, options are considered to be “plain vanilla”, if they have the following basic characteristics: granted “at-the-money”; exerciseability is conditioned upon service through the vesting date; termination of service prior to vesting results in forfeiture; limited exercise period following termination of service; options are non-transferable and non-hedgeable. The expected stock price volatility was determined using a combination of historical and implied volatility of Ciena’s common stock. The fair value is then amortized on a straight-line basis over the requisite service periods of the awards, which is generally the vesting period. Because share-based compensation expense is based on awards that are ultimately expected to vest, it has been reduced to account for estimated forfeitures. SFAS 123(R) requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. In Ciena’s pro forma information required under SFAS 123 for the periods prior to fiscal 2006, Ciena accounted for forfeitures as they occurred. Changes in these inputs and assumptions can materially affect the measure of estimated fair value of our share-based compensation.
Reserve for Inventory Obsolescence
     Ciena writes down inventory that has become obsolete or unmarketable by an amount equal to the difference between the cost of inventory and the estimated market value based on assumptions about future demand and market conditions. During the first six months of fiscal 2006, we recorded a charge of $4.4 million primarily related to excess inventory due to a change in forecasted sales for certain products. In an effort to limit our exposure to delivery delays and to satisfy customer needs for shorter delivery terms, we have transitioned our manufacturing operations from the build-to-order model we have used in recent years, to a build-to-forecast model for some of our product lines, including core transport and switching and metro transport. This change in our inventory purchases exposes us to the risk that our customers will not order those products for which we have forecasted sales, or will purchase less than we have forecasted. If actual market conditions differ from those we have assumed, we may be required to take additional inventory write-downs or benefits.
Restructuring
     As part of its restructuring costs, Ciena provides for the estimated cost of the net lease expense for facilities that are no longer being used. The provision is equal to the fair value of the minimum future lease payments under our contracted lease obligations, offset by the fair value of the estimated sublease payments that we may receive. As of April 30, 2006, Ciena’s accrued restructuring liability related to net lease expense and other related charges was $29.3 million. The total minimum lease payments for these restructured facilities are $50.0 million. These lease payments will be made over the remaining lives of our leases, which range from four months to thirteen years.

38


 

If actual market conditions are less favorable than those we have projected, we may be required to recognize additional restructuring costs associated with these facilities.
Accounts Receivable Trade, Net
     Ciena’s allowance for doubtful accounts is based on our assessment, on a specific identification basis, of the collectibility of customer accounts. Ciena performs ongoing credit evaluations of its customers and generally has not required collateral or other forms of security from its customers. In determining the appropriate balance for Ciena’s allowance for doubtful accounts, management considers each individual customer account receivable in order to determine collectibility. In doing so, management considers creditworthiness, payment history, account activity and communication with such customer. If a customer’s financial condition changes, Ciena may be required to take a charge for an allowance on doubtful accounts. During the first six months of fiscal 2006, Ciena recorded the recovery of a doubtful account in the amount of $2.9 million as a result of payments from customers from whom payment was previously deemed doubtful due to the customers’ financial condition.
Goodwill
     At April 30, 2006, Ciena’s consolidated balance sheet included $232.0 million in goodwill. Due to Ciena’s reorganization into operating segments, SFAS 142 requires that we assign goodwill to Ciena’s reporting units. Ciena has determined its operating segments and reporting units are the same. In accordance with SFAS 142, Ciena tests each reporting unit’s goodwill for impairment on an annual basis, and between annual tests if an event occurs or circumstances change that would, more likely than not, reduce the fair value of the reporting unit below its carrying value. If actual market conditions differ or forecasts change at the time of our annual assessment in fiscal 2006 or in periods prior to our annual assessment, we may be required to record additional goodwill impairment charges.
Intangible Assets
     As of April 30, 2006, Ciena’s consolidated balance sheet included $105.8 million in other intangible assets, net. We account for the impairment or disposal of long-lived assets such as equipment, furniture, fixtures, and other intangible assets in accordance with the provisions of SFAS 144. In accordance with SFAS 144, Ciena tests each intangible asset for impairment whenever events or changes in circumstances indicate that the asset’s carrying amount may not be recoverable. If actual market conditions differ or forecasts change, we may be required to record additional impairment charges in future periods.
Investments
     As of April 30, 2006, Ciena’s minority investments in privately held technology companies were $6.5 million. These investments are generally carried at cost because Ciena owns less than 20% of the voting equity and does not have the ability to exercise significant influence over any of these companies. These investments are inherently high risk as the market for technologies or products manufactured by these companies are usually early stage at the time of the investment by Ciena and such markets may never materialize or become significant. Ciena could lose its entire investment in some or all of these companies. Ciena monitors these investments for impairment and makes appropriate reductions in carrying values when necessary. Ciena recorded a net charge of $0.7 million during the first six months of fiscal 2006, from a decline in the fair value of certain equity investments that was determined to be other than temporary. If market conditions, expected financial performance or the competitive position of the companies in which we invest deteriorate, Ciena may be required to record an additional charge in future periods.
Deferred Tax Valuation Allowance
     As of April 30, 2006, Ciena has recorded a valuation allowance of $1.2 billion against our gross deferred tax assets of $1.2 billion. We calculated the valuation allowance in accordance with the provisions of SFAS 109, “Accounting for Income Taxes,” which requires an assessment of both positive and negative evidence when measuring the need for a valuation allowance. Evidence such as operating results during the most recent three-year period is given more weight than forecasted results, due to our current lack of visibility and the degree of uncertainty that we will achieve the level of future profitability needed to record the deferred assets. Our cumulative loss in the most recent three-year period represents sufficient negative evidence to require a valuation allowance under the provisions of SFAS 109. We intend to maintain a valuation allowance until sufficient positive evidence exists to support its reversal.
Item 3. Quantitative and Qualitative Disclosures About Market Risk

39


 

     The following discussion about Ciena’s market risk disclosures involves forward-looking statements. Actual results could differ materially from those projected in the forward-looking statements. Ciena is exposed to market risk related to changes in interest rates and foreign currency exchange rates. Ciena does not use derivative financial instruments for speculative or trading purposes.
     Interest Rate Sensitivity. Ciena maintains a short-term and long-term investment portfolio. These available-for-sale securities are subject to interest rate risk and will fall in value if market interest rates increase. If market interest rates were to increase immediately and uniformly by 10% from levels at April 30, 2006, the fair value of the portfolio would decline by approximately $35.9 million.
     Foreign Currency Exchange Risk. As a global concern, Ciena faces exposure to adverse movements in foreign currency exchange rates. These exposures may change over time as business practices evolve and if our exposure increases, adverse movement in foreign currency exchange rates could have a material adverse impact on Ciena’s financial results. Historically, Ciena’s primary exposures have been related to non-dollar denominated operating expenses in Europe and Asia where Ciena sells primarily in U.S. dollars. Ciena is prepared to hedge against fluctuations in foreign currency if this exposure becomes material. As of April 30, 2006, the assets and liabilities of Ciena related to non-dollar denominated currencies were not material. Therefore, we do not expect an increase or decrease of 10% in the foreign exchange rate would have a material impact on Ciena’s financial position.
Item 4. Controls and Procedures
Disclosure Controls and Procedures
     As of the end of the period covered by this report, Ciena carried out an evaluation under the supervision and with the participation of Ciena’s management, including Ciena’s Chief Executive Officer and Chief Financial Officer, of Ciena’s disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended). Based upon this evaluation, Ciena’s Chief Executive Officer and Chief Financial Officer concluded that Ciena’s disclosure controls and procedures were effective as of the end of the period covered by this report.
Changes in Internal Control over Financial Reporting
     There was no change in Ciena’s internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934, as amended) during the most recently completed fiscal quarter that has materially affected, or is reasonably likely to materially affect, Ciena’s internal control over financial reporting.
PART II — OTHER INFORMATION
Item 1. Legal Proceedings
     On October 3, 2000, Stanford University and Litton Systems filed a complaint in the United States District Court for the Central District of California against Ciena and several other defendants, alleging that optical fiber amplifiers incorporated into certain of those parties’ products infringe U.S. Patent No. 4,859,016 (the “‘016 Patent”). The complaint seeks injunctive relief, royalties and damages. On October 10, 2003, the court stayed the case pending final resolution of matters before the U.S. Patent and Trademark Office (the “PTO”), including a request for and disposition of a reexamination of the ‘016 Patent. On October 16, 2003 and November 2, 2004, the PTO granted reexaminations of the ‘016 Patent, resulting in a continuation of the stay of the case. On July 11, 2005, the PTO issued a Notice of Intent to Issue a Reexamination Certificate and a Statement of Reasons for Patentability/Confirmation, stating its intent to confirm all claims of ‘016 Patent. As a result, on October 10, 2005, Litton Systems filed a motion with the district court for an order lifting the stay of the case, and defendant Pirelli S.p.A. filed with the PTO a new request for ex parte reexamination of the ‘016 Patent. On December 15, 2005, the PTO denied Pirelli’s request for reexamination. On December 19, 2005, the district court denied Litton Systems’ motion to lift the stay. On January 17, 2006, Pirelli filed a petition for reconsideration of the order denying its request for reexamination. On March 6, 2006, the PTO vacated its Notice of Intent to Issue Reexamination Certificate as premature, reassigned the case to a new examiner for further proceedings, and dismissed as moot Pirelli’s petition for reconsideration. We believe that we have valid defenses to the lawsuit and intend to defend it vigorously in the event the stay of the case is lifted.
     As a result of our merger with ONI Systems Corp. in June 2002, we became a defendant in a securities class action lawsuit. Beginning in August 2001, a number of substantially identical class action complaints alleging

40


 

violations of the federal securities laws were filed in the United States District Court for the Southern District of New York. These complaints name ONI, Hugh C. Martin, ONI’s former chairman, president and chief executive officer; Chris A. Davis, ONI’s former executive vice president, chief financial officer and administrative officer; and certain underwriters of ONI’s initial public offering as defendants. The complaints were consolidated into a single action, and a consolidated amended complaint was filed on April 24, 2002. The amended complaint alleges, among other things, that the underwriter defendants violated the securities laws by failing to disclose alleged compensation arrangements (such as undisclosed commissions or stock stabilization practices) in the initial public offering’s registration statement and by engaging in manipulative practices to artificially inflate the price of ONI’s common stock after the initial public offering. The amended complaint also alleges that ONI and the named former officers violated the securities laws on the basis of an alleged failure to disclose the underwriters’ alleged compensation arrangements and manipulative practices. No specific amount of damages has been claimed. Similar complaints have been filed against more than 300 other issuers that have had initial public offerings since 1998, and all of these actions have been included in a single coordinated proceeding. Mr. Martin and Ms. Davis have been dismissed from the action without prejudice pursuant to a tolling agreement. In July 2004, following mediated settlement negotiations, the plaintiffs, the issuer defendants (including Ciena), and their insurers entered into a settlement agreement, whereby the plaintiffs’ cases against the issuers are to be dismissed. The plaintiffs and issuer defendants subsequently moved the court for preliminary approval of the settlement agreement, which motion was opposed by the underwriter defendants. On February 15, 2005, the district court granted the motion for preliminary approval of the settlement agreement, subject to certain modifications to the proposed bar order, and directed the parties to submit a revised settlement agreement reflecting its opinion. On August 31, 2005, the district court issued a preliminary order approving the stipulated settlement agreement, approving and setting dates for notice of the settlement to all class members. A fairness hearing was held on April 24, 2006, at which time the court took the matter under advisement. If the court determines that the settlement is fair to the class members, the settlement will be approved. The settlement agreement does not require Ciena to pay any amount toward the settlement or to make any other payments.
     On January 18, 2005, Ciena filed a complaint in the United States District Court for the Eastern District of Texas, Marshall Division against Nortel Networks, Inc., Nortel Networks Corporation and Nortel Networks Limited (collectively, “Nortel”), which complaint was subsequently amended. Ciena’s amended complaint charges Nortel with infringement of nine patents related to Ciena’s communications networking systems and technology. Ciena seeks to enjoin Nortel’s infringing activities and recover damages caused by such infringement. On March 14, 2005, Nortel filed an answer to Ciena’s complaint and a counterclaim against Ciena, each of which have subsequently been amended. Nortel’s amended counterclaim charges Ciena with infringement of 13 patents related to Nortel’s communications networking systems and technology, including certain of Nortel’s SONET, ATM and VLAN systems and technology. Nortel’s counterclaim seeks injunctive relief and damages. The court ordered that the case be tried in stages, and that 12 of the 22 total patents in suit (five for Ciena and seven for Nortel) would be at issue in stage one. At the same time, the court stayed all claims relating to the remaining patents. A Markman hearing was held in November 2005 and, on April 25, 2006, the court issued a memorandum opinion construing, or electing not to construe, certain disputed claims relating to the “stage one” patents. Each of the parties has subsequently filed several motions for summary judgment or partial summary judgment on certain of the “stage one” patents, to which oppositions and replies have also been filed. On May 8, 2006, the court granted the parties’ joint request for a continuance of the trial on the “stage one” patents, which is now scheduled for July 2006.
     On April 17, 2006, Nortel filed a new complaint in the United States District Court for the District of Texas, Marshall Division, charging Ciena with infringement of six additional patents related to Nortel’s communications networking systems and technology. Ciena intends to vigorously defend against the suit and to file a counterclaim against Nortel, charging Nortel with infringement of certain additional patents related to Ciena’s communications networking systems and technology.
     In addition to the matters described above, we are subject to various legal proceedings, claims and litigation arising in the ordinary course of business. While the outcome of these matters is currently not determinable, we do not expect that the ultimate costs to resolve these matters will have a material effect on our results of operations, financial position or cash flows.

Item 1A. Risk Factors
     Investing in our securities involves a high degree of risk. In addition to the other information contained in this report, you should consider the following risk factors before investing in our securities.
We face intense competition that could hurt our sales and our ability to achieve and maintain profitability.
     The markets in which we compete for sales of networking equipment, software and services are extremely competitive, particularly the market for sales to telecommunications service providers. Competition in these markets is based on any one or a combination of the following factors: price, functionality, manufacturing capability, installation, services, existing business and customer relationships, scalability and the ability of products and services to meet customers’ immediate and future network requirements. A small number of very large companies have historically dominated the communications networking equipment industry. Our industry has also increasingly experienced competition from low-cost producers in Asia. Many of our competitors have substantially greater financial, technical and marketing resources, greater manufacturing capacity and better established relationships with incumbent carriers and other potential customers than us. As a result of increased merger activity among communication service providers, there has been speculation of consolidation among networking equipment providers, which, if it occurred, could cause some competitors to grow even larger and more powerful. On April 2, 2006, Alcatel and Lucent, two large competitors, announced a definitive agreement to merge, and the effect of this merger on us, should it occur, may be adverse to our competitive position.
     We also compete with a number of smaller companies that provide significant competition for a specific product or market. These competitors often base their products on the latest available technologies. Due to the narrower focus of their efforts, these competitors may achieve commercial availability of their products more quickly and may be more attractive to customers. As we seek to expand our channel sales strategy, we also may face competition from resellers and distributors of some of our products, who may be competitors in other customer markets or with respect to complementary technologies.
     Increased competition in our markets has resulted in aggressive business tactics, including:
    intense price competition;
 
    discounting resulting from sales of used equipment or inventory that a competitor has written down or written off;
 
    early announcements of competing products and extensive marketing efforts;
 
    “one-stop shopping” options;
 
    competitors offering to repurchase our equipment from existing customers;
 
    customer financing assistance;
 
    marketing and advertising assistance; and
 
    intellectual property assertions and disputes.
     The tactics described above can be particularly effective in an increasingly concentrated base of potential customers such as communications service providers. Our inability to compete successfully in our markets would harm our sales and our ability to achieve and maintain profitability.
Our revenue and operating results can fluctuate unpredictably from quarter to quarter.
     Our revenue can fluctuate unpredictably from quarter to quarter. Fluctuations in our revenue can lead to even greater fluctuations in our operating results. Our budgeted expense levels depend in part on our expectations of future revenue. Any substantial adjustment to expenses to account for lower levels of revenue is difficult and takes time. Consequently, if our revenue declines, our levels of inventory, operating expense and general overhead would be high relative to revenue, resulting in additional operating losses.
     Other factors contribute to fluctuations in our revenue and operating results, including:
    the level of demand for our products and the timing and size of customer orders, particularly from telecommunications service provider customers;

42


 

    satisfaction of contractual customer acceptance criteria and related revenue recognition requirements;
 
    availability of an adequate supply of components and sufficient manufacturing capacity;
 
    changes in customers’ requirements, including delay, changes or cancellations of orders from customers;
 
    the introduction of new products by us or our competitors;
 
    readiness of customer sites for installation;
 
    any significant payment by us associated with the resolution of pending legal proceedings or compliance with applicable regulations;
 
    changes in accounting rules; and
 
    changes in general economic conditions as well as those specific to our market segments.
     Many of these factors are beyond our control, particularly in the case of large carrier orders and multi-vendor or multi-technology network builds where the achievement of certain performance thresholds for acceptance is subject to the readiness and performance of the customer or other providers and changes in customer requirements or installation plans. Any one or a combination of the factors above may cause our revenue and operating results to fluctuate from quarter to quarter. These revenue fluctuations may make it difficult to manage our business and achieve or maintain profitability. As a consequence, our revenues and operating results for a particular quarter may be difficult to predict and our prior results are not necessarily indicative of results likely in future periods.
Our gross margin may fluctuate from quarter to quarter and our product gross margin may be adversely affected by a number of factors, some of which are beyond our control.
     Our gross margin fluctuates from period to period and our product gross margin may be adversely affected by numerous factors, including:
    increased price competition, including competition from low-cost producers in Asia;
 
    the mix in any period of higher and lower margin products and services;
 
    sales volume during the period;
 
    charges for excess or obsolete inventory;
 
    changes in the price or availability of components for our products;
 
    our ability to continue to reduce product manufacturing costs;
 
    introduction of new products, with initial sales at relatively small volumes with resulting higher production costs; and
 
    increased warranty or repair costs.
     The factors discussed above regarding fluctuations in revenue and operating results can also affect gross margin. We expect product gross margin to continue to fluctuate from quarter to quarter. Fluctuations in product gross margin may make it difficult to manage our business and achieve or maintain profitability. As a consequence, our gross margin for a particular quarter may be difficult to predict and our prior results are not necessarily indicative of results likely in future periods.
Our business and results of operations are significantly affected by conditions in the communications industry, including increases in consolidation activity.
     The last few years have seen substantial changes in the communications industry. Many of our customers and potential customers, including telecommunications service providers that have historically provided a significant portion of our sales, have confronted static or declining revenue for their traditional voice services. Traditional

43


 

communications service providers are under increasing competitive pressure from providers within their industry and other participants that offer, or seek to offer, overlapping or similar services. These pressures are likely to continue to cause communications service providers to seek to minimize the costs of the equipment that they buy and may cause static or reduced capital expenditures by customers or potential customers. These competitive pressures may also result in pricing becoming a more important factor in customer purchasing decisions. Increased focus on pricing may favor low-cost vendors in Asia and larger competitors that can spread the effect of price discounts across a broader offering of products and services and across a larger customer base.
     Several large communications service providers have recently completed merger transactions. These included the mergers of Verizon and MCI, and SBC and AT&T, all of which have been significant customers during prior periods. In addition, AT&T has also announced its plans to acquire BellSouth, which has also been a significant customer during prior periods. These mergers will have a major impact on the future of the telecommunications industry. They will further increase concentration of purchasing power among a few large service providers and may result in delays in, or the curtailment of, investments in communications networks, as a result of changes in strategy, network overlap, cost reduction efforts or other considerations. These industry conditions may negatively affect our business, financial condition and results of operation.
We may not be successful in selling our products into new markets and developing and managing new sales channels.
     We continue to take steps to sell our expanded product portfolio into new markets and to a broader customer base, including communication service providers, enterprises, cable operators, and federal, state and local governments. To succeed in these markets, we believe we must develop and manage new sales channels and distribution arrangements. We expect these relationships to be an increasing part of our business as we seek to grow. Because we have only limited experience in developing and managing such channels, we may not be successful in reaching additional customer segments, expanding into new geographic regions, or reducing the financial risks of entering new markets and pursuing new customer segments. In addition, sales to federal, state and local governments require compliance with complex procurement regulations with which we have little experience. We may be unable to increase our sales to government contractors if we determine that we cannot comply with applicable regulations. Our failure to comply with regulations for existing contracts could result in civil, criminal or administrative proceedings involving fines and suspension or debarment from federal government contracts. Failure to manage additional sales channels effectively would limit our ability to succeed in these new markets and could adversely affect our ability to grow our customer base and revenues.
Network equipment sales to large communications service providers often involve, lengthy sales cycles and protracted contract negotiations and may require us to assume terms or conditions that negatively affect our pricing, payment and timing of revenue recognition.
     In recent years we have sought to add large, incumbent communication service providers as customers for our products, software and services. Our future success will depend on our ability to maintain and expand our sales to these existing communications service provider customers and add new customers. Many of our competitors have long-standing relationships with communications service providers, which can pose significant obstacles to our sales efforts. Sales to large communications service providers typically involve lengthy sales cycles, protracted or difficult contract negotiations, and extensive product testing and network certification. We are sometimes required to assume terms or conditions that negatively affect pricing, payment and the timing of revenue recognition in order to consummate a sale. This may negatively affect the timing of revenue recognition, which would, in turn, negatively affect our gross margin and results of operations. Communications service providers may ultimately insist upon terms and conditions, that we deem too onerous or not in our best interest. As a result, we may incur substantial expenses and devote time and resources to potential relationships that never materialize.
Continued shortages in component supply or manufacturing capacity could increase our costs, adversely affect our results of operations and constrain our ability to grow our business.
     As we have expanded our product portfolio, increased our use of contract manufacturers and increased our product sales in recent years, manufacturing capacity and supply constraints related to components and subsystems have become increasingly significant issues for us. We have encountered and continue to experience component shortages that have affected our operations and ability to deliver products timely to customers. Growth in customer demand for the communications networking products supplied by us, our competitors and other third parties, has resulted in supply constraints among providers of some components used in our products. In addition, environmental regulations, such as the Restriction of the Use of Certain Hazardous Substances (RoHS) adopted by the European Union, have resulted in increased demand for compliant components from suppliers. As a result, we may experience delays or difficulty obtaining compliant components from suppliers. Component shortages and manufacturing

44


 

capacity constraints may also arise, or be exacerbated by difficulties with our suppliers or contract manufacturers, or our failure to adequately forecast our component or manufacturing needs. If shortages or delays persist or worsen, the price of required components may increase, or the components may not be available at all. If we are unable to secure the components or subsystems that we require at reasonable prices, or are unable to secure manufacturing capacity adequate to meet our needs, we may experience delivery delays and may be unable to satisfy our contractual obligations to customers. As a result, our revenue and gross margin could be materially affected. Delays could also limit our opportunities to pursue additional growth or revenue opportunities and could harm our business reputation and customer relationships.
Product performance problems could damage our business reputation and limit our sales prospects.
     The development and production of new products with high technology content is complicated and often involves problems with software, components and manufacturing methods. Modifying our products to enable customers to integrate them into a new type of network architecture entails similar risks. If significant reliability, quality, or network monitoring problems develop as a result of our product development, manufacturing or integration, a number of negative effects on our business could result, including:
    increased costs associated with fixing software or hardware defects, including service and warranty expenses;
 
    payment of liquidated damages for performance failures;
 
    high inventory obsolescence expense;
 
    delays in collecting accounts receivable;
 
    reduced orders from existing or potential customers; and
 
    damage to our reputation.
     Because we outsource manufacturing and use a direct order fulfillment model for certain of our products, we may be subject to product performance problems resulting from the acts or omissions of these third parties. These product performance problems could damage our business reputation and negatively affect our sales.
We must continue to make substantial and prudent investments in product development in order to keep pace with technological advances and succeed in existing and new markets for our products.
     In order to be successful, we must balance our initiatives to reduce our operating costs against the need to keep pace with technological advances. The market for communications networking equipment, software and services is characterized by rapid technological change, frequent introductions of new products, and recurring changes in customer requirements. To succeed, we must continue to develop new products and new features for existing products that meet customer requirements and market demand. In addition, we must be able to identify and gain access, including any applicable third party licenses, to new technologies as our market segments evolve. Because our market segments are constantly evolving, our research and development strategy and allocation of development resources must be dynamic. We may decide that changes in demand, technology or other market conditions no longer warrant continued investment in a product or technology. These decisions are difficult and may be disruptive to our business and our relationships with customers. We may also allocate development resources toward products or technologies for which market demand is ultimately lower than anticipated. Managing our efforts to keep pace with new technologies and reduce operating expense is difficult and there is no assurance that we will be successful.
We may be required to take further write-downs of goodwill and other intangible assets.
     As of April 30, 2006, we had $232.0 million of goodwill on our balance sheet. This amount primarily represents the remaining excess of the total purchase price of our acquisitions over the fair value of the net assets acquired. At April 30, 2006, we had $105.8 million of other intangible assets on our balance sheet. The amount primarily reflects purchased technology from our acquisitions. At April 30, 2006, goodwill and other intangible assets represented approximately 18.6% of our total assets. During the fourth quarter of 2005, we incurred a goodwill impairment charge of approximately $176.6 million and an impairment of other intangibles of $45.7 million. If we are required to record additional impairment charges related to goodwill and other intangible assets, such charges would have the effect of decreasing our earnings or increasing our losses in such period. If we are required to take a substantial

45


 

impairment charge, our earnings per share or net loss per share could be materially adversely affected in such period.
We may experience unanticipated delays in the development and enhancement of our products that may negatively affect our competitive position and business.
     Because our products are based on complex technology, we can experience unanticipated delays in developing, improving, manufacturing or deploying them. Each step in the development life cycle of our products presents serious risks of failure, rework or delay, any one of which could decrease the timing and cost effective development of such product and could affect customer acceptance of the product. Specialized application specific integrated circuits (“ASICs”) and intensive software testing and validation are key to the timely introduction of enhancements to several of our products, and schedule delays are common in the final validation phase, as well as in the manufacture of specialized ASICs. In addition, unexpected intellectual property disputes, failure of critical design elements, and a host of other execution risks may delay or even prevent the introduction of these products. If we do not develop and successfully introduce products in a timely manner, our competitive position may suffer and our business, financial condition and results of operations would be harmed.
We may incur significant costs and our competitive position may suffer as a result of our efforts to protect and enforce our intellectual property rights or respond to claims of infringement from others.
     Despite efforts to protect our proprietary rights, unauthorized parties may attempt to copy or otherwise obtain and use our products or technology. This is likely to become an increasingly important issue as we expand our operations and product development into countries that provide a lower level of intellectual property protection. Monitoring unauthorized use of our products is difficult, and we cannot be certain that the steps that we are taking will prevent unauthorized use of our technology. If competitors are able to use our technology, our ability to compete effectively could be harmed.
     In recent years, we have filed suit to enforce our intellectual property rights and, from time to time, have been subject to litigation and other third party intellectual property claims, including as a result of our indemnification obligations to customers or resellers that purchase our products. The frequency of these assertions is increasing as patent holders, including entities that are not in our industry and that purchase patents as an investment or to monetize such rights by obtaining royalties, use infringement assertions as a competitive tactic and a source of additional revenue. Intellectual property claims can significantly divert the time and attention of our personnel and result in costly litigation. Our pending patent infringement litigation with Nortel Networks has resulted in, and is likely to continue to result in, significant costs. If we are unsuccessful in this litigation, we may be required to pay significant damages, and could be enjoined from marketing or selling certain products. Intellectual property infringement claims can also require us to pay substantial royalties, enter into license agreements and/or develop non-infringing technology. Accordingly, the costs associated with third party intellectual property claims could adversely affect our business, results of operations and financial condition.
We may be required to write off significant amounts of inventory.
     In recent years, we have placed the majority of our orders to manufacture components or complete assemblies for many of our products only when we have firm orders from our customers. Because this practice can result in delays in the delivery of products to customers, we are increasingly ordering equipment and components from our suppliers based on forecasts of customer demand across all of our products. We believe this change is necessary in response to increased customer insistence upon shortened delivery terms. This change in our inventory purchases exposes us to the risk that our customers will not order those products for which we have forecasted sales, or will purchase fewer than the number of products we have forecasted. We may also be required to write off inventory as a result of the effect of environmental regulations such as the Restriction of the Use of Certain Hazardous Substances (RoHS) adopted by the European Union. Compliance with this regulation takes effect July 1, 2006. As a result of previous component purchases that we based on forecasted sales, we currently hold inventory that includes non-compliant components. If we are unable to locate alternate demand for these non-compliant components outside of the European Union, we may be required to write off or write down this inventory. If we are required to write off, or write down inventory, it may result in an accounting charge that could materially affect our results of operations for the quarter in which such charge occurs.
We must manage our relationships with electronic manufacturing service (EMS) providers in order to ensure that our product requirements are met timely and effectively.
     We rely on EMS providers to perform the majority of the manufacturing operations for our products and components, and are increasingly utilizing overseas suppliers, particularly in Asia. Because EMS providers are

46


 

subject to many of the same risks as equipment vendors serving the communications industry, many EMS providers have experienced their own financial difficulties in recent years. The qualification of our EMS providers is a costly and time-consuming process, and these manufacturers build product for other companies, including our competitors. We are constantly reviewing our manufacturing capability, including the work of our EMS providers, to ensure that our production requirements are met in terms of cost, capacity, quality and reliability. From time to time, we may decide to transfer the manufacturing of a product from one EMS provider to another, to better meet our production needs. It is possible that we may not effectively manage this transition or the new contract manufacturer may not perform as well as expected. As a result, we may not be able to fill orders in a timely manner, which could harm our business. In addition, we do not have contracts in place with some of these providers. Our inability to effectively manage our relationships with our EMS providers, particularly overseas, could negatively affect our business and results of operations.
We depend on a limited number of suppliers, and for some items we do not have a substitute supplier.
     We depend on a limited number of suppliers for our product components and subsystems, as well as for equipment used to manufacture and test our products. Our products include several components for which reliable, high-volume suppliers are particularly limited. Some key optical and electronic components we use in our products are currently available only from sole or limited sources, and in some cases, that source also is a competitor. As a result of this concentration in our supply chain, particularly for optical components, our business and operations would be negatively affected if our suppliers were to experience any significant disruption affecting the quality, availability or timely delivery of components. The loss of a source of key components could require us to re-engineer products that use those components, which would increase our costs and negatively affect our product gross margin. The partial or complete loss of a sole or limited source supplier could result in lost revenue, added costs and deployment delays that could harm our business and customer relationships.
Our international operations could expose us to additional risk and result in increased operating expense.
     We market, sell and service our products globally. We have established offices around the world, including in North America, Europe, Latin America and the Asia Pacific region. We have also established a development operation in India to pursue offshore development resources. In addition, we are increasingly relying upon overseas suppliers, particularly in Asia, to manufacture our products and components. We expect that our international activities will be dynamic over the foreseeable future as we enter some new markets and withdraw from or reduce operations in others in order to match our resources with revenue opportunities. These changes to our international operations will require significant management attention and financial resources. In some countries, our success will depend in part on our ability to form relationships with local partners. Our inability to identify appropriate partners or reach mutually satisfactory arrangements for international sales of our products could impact our ability to maintain or increase international market demand for our products.
     International operations are subject to inherent risks, and our future results could be adversely affected by a number of factors, including:
    greater difficulty in collecting accounts receivable and longer collection periods;
 
    difficulties and costs of staffing and managing foreign operations;
 
    the impact of recessions in economies outside the United States;
 
    reduced protection for intellectual property rights in some countries;
 
    adverse tax consequences;
 
    political and economic instability;
 
    trade protection measures, export compliance, qualification do transact business and other regulatory requirements;
 
    effects of changes in currency exchange rates; and
 
    natural disasters and epidemics.
Our efforts to offshore certain resources and operations to India may not be successful and may expose us to

47


 

unanticipated costs or liabilities.
     We have established a development operation in India and expect to increase hiring of personnel for this facility during the remainder of fiscal 2006. We have limited experience in offshoring our business functions, particularly development operations, and there is no assurance that our plan will enable us to achieve meaningful cost reductions or greater resource efficiency. Further, offshoring to India involves significant risks, including:
    the hiring and retention of appropriate engineering resources, particularly in light of the rapid increase in similar activity in India by other companies that are competing to hire engineers with the skills that we require;
 
    the knowledge transfer related to our technology and exposure to misappropriation of intellectual property or confidential information, including information that is proprietary to us, our customers and other third parties;
 
    heightened exposure to changes in the economic, security and political conditions of India;
 
    currency exchange and tax risks associated with offshore operations; and
 
    development efforts that do not meet our requirements because of language, cultural or other differences associated with international operations, resulting in errors or delays.
     Difficulties resulting from the factors above and other risks associated with offshoring could expose us to increased expense, impair our development efforts, harm our competitive position and damage our reputation with existing and potential customers. These factors could be disruptive to our business and may cause us to incur substantial unanticipated costs or expose us to unforeseen liabilities.
The steps that we are taking to restructure our operations and align our resources with market opportunities could disrupt our business.
     We have taken several steps, including reductions in force, office closures, and internal reorganizations to reduce the size and cost of our operations and to better match our resources with our market opportunities. We expect to continue to make changes to our operations and allocation of resources in order improve efficiency and reduce operating expense. These efforts could be disruptive to our business. In recent fiscal quarters, these actions have focused on consolidating and restructuring our research and development resources in order to transition away from product-based or location-specific development and leverage our engineering resources across a wider range of product and solutions sets. Reductions to headcount and other cost cutting measures may result in the loss of technical expertise that could adversely affect our research and development efforts and ability to meet product development schedules. Modification of research and development strategies, changes in allocation or resources and decisions to discontinue or cease to enhance products, could be disruptive to our relationships with customers and could limit new business opportunities for affected products.
     Our efforts to reduce expense or improve efficiency have resulted in the recording of accounting charges in prior periods. These include inventory and technology-related write-offs, workforce reduction costs and charges relating to consolidation of excess facilities. If we are required to take a substantial charge, our earnings per share or net loss per share would be adversely affected in such period. If we cannot manage our cost reduction and restructuring efforts effectively, our business, results of operations and financial condition could be harmed.
Our exposure to the credit risks of our customers and resellers may make it difficult to collect receivables and could adversely affect our operating results and financial condition.
     Industry and economic conditions have weakened the financial position of some of our customers. To sell to some of these customers, we may be required to take risks of uncollectible accounts. We may be exposed to similar risks relating to third party resellers and other sales channel partners, as we intend to increasingly utilize such parties as we enter into new geographies, particularly in Europe. While we monitor these situations carefully and attempt to take appropriate measures to protect ourselves, it is possible that we may have to write down or write off doubtful accounts. Such write-downs or write-offs would negatively affect our operating results for the period in which they occur, and, if large, could have a material adverse effect on our operating results and financial condition.
If we are unable to attract and retain qualified personnel, we may be unable to manage our business effectively.
     If we are unable to retain and motivate our existing employees and attract qualified personnel to fill key positions, we may be unable to manage our business effectively. If we lose members of our management team or

48


 

other key personnel, it may be difficult to replace them. Competition to attract and retain highly skilled technical and other personnel with experience in our industry can be intense and our employees have been the subject of targeted hiring by our competitors. During April 2006 we announced a change in leadership of our sales organization. There can be no assurance that this change will not be disruptive to our sales function or negatively affect employee retention. Because we generally do not have employment contracts with our employees, we must rely upon providing competitive compensation packages and a high-quality work environment in order to retain and motivate employees. We have paid our employees significantly reduced or no bonuses for several years. In addition, we have informed employees that we will not be issuing stock options at the same level as historical grants. In addition to these compensation issues, we must continue to motivate and retain employees, which may be difficult due to morale challenges posed by our continuing workforce reductions and offshoring of certain operations.
Our failure to manage our relationships with service delivery partners effectively could adversely impact our financial results and relationship with customers.
     We rely on a number of service delivery partners, both domestic and international, to complement our global service and support resources. We expect to increasingly rely upon third party service delivery partners for the installation of our equipment in larger network builds, which often include more onerous installation, testing and acceptance terms. In order to ensure that we timely install our products and satisfy obligations to our customers, we must identify, train and certify additional appropriate partners. The certification of these partners can be costly and time-consuming, and these partners service products for other companies, including our competitors. We may not be able to effectively manage our relationships with our partners and we cannot be certain that they will be able to deliver our services in the manner or time required. If our service partners are unsuccessful in delivering services:
    we may suffer delays in recognizing revenues in cases where revenue recognition is dependent upon product installation, testing and acceptance;
 
    our services revenue may be adversely affected; and
 
    our relationship with customers could suffer.
We may be required to assume warranty, service, development and other unexpected obligations in connection with our resale of complementary products of other companies.
     We have entered into agreements with strategic partners that permit us to distribute the products of other companies. As part of our strategy to diversify our product portfolio and customer base, we may enter into additional resale agreements in the future. To the extent we succeed in reselling the products of these companies, we may be required by customers to assume certain warranty, service and development obligations. While our suppliers often agree to support us with respect to these obligations, we may be required to extend greater protection in order to effect a sale. Moreover, our suppliers are relatively small companies with limited financial resources. If they are unable to satisfy these obligations, we may have to expend our own resources to do so. This risk is amplified because the equipment that we are selling has been designed and manufactured by other third parties and may be subject to warranty claims, the magnitude of which we are unable to evaluate fully. We may be required to assume warranty, service, development and other unexpected obligations in connection with our resale of complementary products of other companies.
Our strategy of pursuing strategic acquisitions and investments may expose us to increased costs and unexpected liabilities.
     Our business strategy includes acquiring or making strategic investments in other companies to increase our portfolio of products and services, expand the markets we address, diversify our customer base and acquire or accelerate the development of new or improved products. To do so, we may use cash, issue equity that would dilute our current shareholders’ ownership, incur debt or assume indebtedness. Strategic investments and acquisitions involve numerous risks, including:
    difficulties in integrating the operations, technologies and products of the acquired companies;
 
    diversion of management’s attention;
 
    potential difficulties in completing projects of the acquired company and costs related to in-process
 
    the potential loss of key employees of the acquired company;
 
    subsequent amortization expenses related to intangible assets and charges associated with impairment of

49


 

      goodwill;
 
    ineffective internal controls over financial reporting for purposes of Section 404 of the Sarbanes-Oxley Act;
 
    dependence on unfamiliar supply partners; and
 
    exposure to unanticipated liabilities, including intellectual property infringement claims.
     As a result of these and other risks, any acquisitions or strategic investments may not reap the intended benefits and may ultimately have a negative impact on our business, results of operation and financial condition.
We may be adversely affected by fluctuations in currency exchange rates.
     Historically, our primary exposure to currency exchange rates has been related to non-U.S. dollar denominated operating expenses in Europe, Asia and Canada where we sell primarily in U.S. dollars. As we increase our international sales and utilization of international suppliers, we expect to transact additional business in currencies other than the U.S. dollar. As a result, we will be subject to the possibility of greater effects of foreign exchange translation on our financial statements. For those countries outside the United States where we have significant sales, a devaluation in the local currency would result in reduced revenue and operating profit and reduce the value of our local inventory presented in our financial statements. In addition, fluctuations in foreign currency exchange rates may make our products more expensive for customers to purchase or increase our operating costs, thereby adversely affecting our competitiveness. To date, we have not significantly hedged against foreign currency fluctuations; however, we may pursue hedging alternatives in the future. Although exposure to currency fluctuations to date has not had an adverse effect on our business, there can be no assurance that exchange rate fluctuations in the future will not have a material adverse effect on our revenue from international sales and, consequently, our business, operating results and financial condition.
Failure to maintain effective internal controls over financial reporting could have a material adverse effect on our business, operating results and stock price.
     Section 404 of the Sarbanes-Oxley Act of 2002 requires that we include in our annual report on Form 10-K, a report containing management’s assessment of the effectiveness of our internal controls over financial reporting as of the end of our fiscal year and a statement as to whether or not such internal controls are effective. Such report must also contain a statement that our independent registered public accounting firm has issued an attestation report on management’s assessment of such internal controls.
     We initially became subject to these requirements for our fiscal year ended October 31, 2005. Compliance with these requirements has resulted in, and is likely to continue to result in, significant costs, the commitment of time and operational resources and the diversion of management’s attention. Growth of our business, including our broader product portfolio and increased transaction volume, will necessitate ongoing changes to our internal control systems, processes and infrastructure, including our information systems. Our increasingly global operations, including our development facility in India and offices abroad, will pose additional challenges to our internal control systems as their operations become more significant. We cannot be certain that our current design for internal control over financial reporting, and any modifications necessary to reflect changes in our business, will be sufficient to enable management or our independent registered public accounting firm to determine that our internal controls are effective as of the end of fiscal 2006 or on an ongoing basis. If we are unable to assert that our internal controls over financial reporting are effective (or if our independent registered public accounting firm is unable to attest that our management’s report is fairly stated or they are unable to express an opinion on our management’s assessment of the effectiveness of internal controls over financial reporting), our business may be harmed. Market perception of our financial condition and the trading price of our stock may be adversely affected and customer perception of our business may suffer.
Our business is dependent upon the proper functioning of our information systems and upgrading these systems may result in disruption to our operating processes and internal controls.
     The efficient operation of our business is dependent on the successful operation of our information systems. In particular, we rely on our information systems to process financial information, manage inventory and administer our sales transactions. In an effort to improve the efficiency of our operations, achieve greater automation and support the growth of our business, we are in the process of upgrading certain information systems and expect to implement a new version of our Oracle management information system during fiscal 2007. As a result of these changes, we anticipate that we will have to modify a number of our operational processes and internal control procedures to

50


 

conform to the work-flows of new or upgraded information systems. We will also have to undergo a process of validating the data in any new system to ensure its integrity and will need to train our personnel. We cannot assure you that these changes to our information systems will occur without some level of disruption of our operating processes and controls. Any material disruption, malfunction or similar problems with our information systems could negatively impact our business operations.
Obligations associated with our outstanding indebtedness on our convertible notes may adversely affect our business.
     At April 30, 2006, indebtedness on outstanding 3.75% Convertible Notes due February 1, 2008 and 0.25% Convertible Senior Notes due May 1, 2013 totaled $842.3 million in aggregate principal. Our indebtedness and repayment obligations could have important negative consequences, including:
    increasing our vulnerability to general adverse economic and industry conditions;
 
    limiting our ability to obtain additional financing;
 
    reducing the availability of cash resources available for other purposes, including capital expenditures;
 
    limiting our flexibility in planning for, or reacting to, changes in our business and the industry in which we compete; and
 
    placing us at a possible competitive disadvantage to competitors that have better access to capital resources.
     We may also add additional indebtedness such as equipment loans, working capital lines of credit and other long term debt. Our repayment obligations associated with our convertible notes may adversely affect our business.
Our stock price is volatile.
     Our common stock price has experienced substantial volatility in the past, and may remain volatile in the future. Volatility can arise as a result of a number of the factors discussed in this “Risk Factors” section, as well as divergence between our actual or anticipated financial results and published expectations of analysts, and announcements that we, our competitors, or our customers may make.

(c) The following table provides information with respect to any purchase made by or on behalf of Ciena, or any “affiliated purchaser” as defined in 17 C.F.R. § 240.10b-18(a)(3), of shares of any class of equity securities registered by Ciena pursuant to Section 12 of the Securities Exchange Act of 1934, as amended:

*   Not applicable. See description of repurchase activity below.
  (1)   As initially disclosed in our Form 10-Q for the first quarter of fiscal 2005, Ciena does not repurchase its shares in open market transactions. The repurchase activity in the table above consists solely of Ciena’s repurchase of outstanding

51


 

      shares in private transactions with certain former employees. Pursuant to the terms of equity compensation plans and certain award agreements that Ciena assumed in connection with its acquisitions of WaveSmith Networks, Inc. and Catena Networks Inc., employees were permitted exercise certain stock options prior to vesting. Under these plans, upon the employee’s termination of employment, Ciena is granted the right to repurchase the shares issued, to the extent that the option has not vested, at the grantee’s exercise price. If Ciena does not exercise this repurchase right, the shares vest and remain owned by the grantee.
 
      Ciena believes it is in the best interest of its shareholders, and it has been Ciena’s corporate practice, to repurchase shares subject to these award agreements if the closing price of such shares on the NASDAQ National Market during the 30 day period following the grantee’s termination of employment is greater than the grantee’s exercise price. As of May 1, 2006, no shares remained subject to repurchase pursuant to the terms above and Ciena’s repurchase rights have lapsed.

Item 5. Other Information
Adoption of Incentive Bonus Plan
      On May 30, 2006, the Compensation Committee adopted an Incentive Bonus Plan (“Bonus Plan”) pursuant to which Ciena may pay cash bonuses to eligible employees, which may include executive officers. Bonuses will equal a target percentage of an eligible employee’s annual base salary and will be paid in quarterly amounts upon the satisfaction of certain corporate financial goals and any applicable functional performance goals for that fiscal quarter. The Compensation Committee has broad authority to determine eligibility under the Bonus Plan, set the aggregate dollar amount available for payment of bonuses in a fiscal period, establish financial and performance goals, and determine applicable target bonus percentages for all employees. A copy of the Bonus Plan is filed with this report as Exhibit 10.1.
      The Compensation Committee made no change to the target percentages that were in place under Ciena’s prior bonus program, including the target percentages for executive officers. These are 100% of annual salary for the Chief Executive Officer, 75% of annual salary for the Chief Financial Officer; and 50% of annual salary for the other executive officers. Ciena has not paid bonuses to its executive officers under the prior bonus program since 2001, and that program is superseded by the Bonus Plan.
      For the third quarter of fiscal 2006, eligible employees, including executive officers, will receive bonuses equal to half of their applicable target bonuses if Ciena achieves certain financial goals related to as adjusted net income, and if the employees satisfy any applicable functional goals. As adjusted net income generally excludes certain charges and credits that are required by GAAP because they are unusual, non-recurring or unrelated to the ongoing operation of business in the ordinary course, do not involve cash expenditure or their timing and magnitude is outside of Ciena’s control. If Ciena exceeds the financial goals established by the Compensation Committee, employees may receive up to 100% of their applicable target bonuses. The Compensation Committee may elect to use different target financial goals under the Bonus Plan in future periods, including revenue, net income, earnings per share, or such other financial measures as it determines in its sole discretion.
Amendment to ESPP
     On May 30, 2006, the Compensation Committee amended the ESPP, effective September 15, 2006, to shorten the offer period under the ESPP from two years to six months. As a result of this change, the offer period and any purchase period will be the same six-month period. Under the amended ESPP, the applicable purchase price equals 95% of the fair market value of Ciena common stock on the last day of each purchase period. Prior to the amendment, the purchase price equaled 15% less than the fair market value of Ciena common stock on either the first day of an offer period or the last day of a purchase period, whichever was lower. Employees enrolled in the ESPP as of March 16, 2006, the most recent purchase date, will be permitted to complete the remaining purchase periods in their current offer period.

  (o)   Target Bonus — The targeted amount of Bonus Award established for each Eligible Employee, expressed as a percentage of the Eligible Employee’s Base Salary corresponding to the Eligible Employee’s position or grade level at the end of the applicable Bonus Period, assuming the Financial Goals and Performance Goals for such Bonus Period are achieved at the 100% level established by the Committee.
     3. Designation of Participants. The Committee shall designate the Eligible Grade Levels from which it shall select Eligible Employees to become Participants for a Bonus Period. The Committee also shall approve as Participants such other Eligible Employees who are recommended for participation by the CEO. Designation of a person as an Eligible Employee or a Participant for any Bonus Period shall not bind the Committee to designate the person in any other Bonus Period.
     4. Establishment of Financial Goals, Performance Goals, and Target Bonus Percentages. For each Bonus Period, the Committee shall establish in writing (a) the Financial Goals for the Bonus Period, which may consist of a range, (b) the Performance Goals, if any, (c) the Target Bonus percentage for each Eligible Grade Level (or group of Eligible Grade levels), and (d) any formulae for adjusting the Target Bonus percentages for over- or under-achievement of the Financial Goals or the Performance Goals.
     5. Determination of Awards.
  (a)   As soon as practicable after the end of each Bonus Period, the Committee shall determine whether the Financial Goals and, to the extent applicable, the Performance Goals for the Bonus Period were achieved with respect to each Participant, and, if so, at what level of achievement under the formulae established for the Bonus Period.

  (a)   For any Bonus Period, no Bonus Award shall be payable or paid to a Participant who does not remain an Eligible Employee throughout the Bonus Period or who on the payment date for the Bonus Award has ceased to be an employee of the Company or a Subsidiary, unless such termination of employment from the Company or the Subsidiary was (i) on account of death, retirement on or after age 65 or disability, or (ii) as a direct result of the sale of a Subsidiary, affiliate or business unit of the Company, a restructuring or realignment plan, or other Company-initiated termination, other than for cause).
 
  (b)   Except to the extent the Participant is or becomes ineligible to receive a Bonus Award pursuant to Section 6(a), Bonus Awards shall be immediately and fully vested upon the Committee’s authorization of payment of awards for the applicable Bonus Period. In general, Bonus Awards shall be paid to Participants within a reasonable time after the Committee’s authorization of such awards.
 
  (c)   All payments made under this Plan shall be subject to any required withholdings.
 
  (d)   Bonus Awards shall be payable solely from the general assets of the Company and its Subsidiaries. No Participant shall have any right to, or interest in, any specific assets of the Company or any Subsidiary in respect of Bonus Awards.
     7. No Assignment. Bonus Awards authorized under this Plan shall be paid only to Participants (or, in the event of a Participant’s death, to the Participant’s heirs). No Bonus Award, nor any part thereof, and no right or claim to any of the moneys payable pursuant to the provisions of this Plan shall be anticipated, assigned, or otherwise encumbered, nor be subject to attachment, garnishment, execution or levy of any kind, prior to the actual payment and delivery of said amount to the Participant and any attempted assignment or other encumbrance or attachment, garnishment, execution or levy shall be of no force or effect, except as otherwise provided by law. Notwithstanding the above, if a Participant is adjudged incompetent, the Committee may direct that any amounts payable be paid to the Participant’s guardian or legal representative.
     8. Employment and Plan Rights. The Plan shall not be deemed to give any Eligible Employee or Participant the right to be retained in the employ of the Company or any Subsidiary, nor shall the Plan interfere with the right of the Company or any Subsidiary to discharge any employee at any time, nor shall the Plan be deemed to give any employee any right to any Bonus Award until such award is authorized in accordance with Section 5.
     9. Administration and Authority. The Plan shall be administered by the Committee except as otherwise provided herein. The Committee shall, consistent with the Plan,

3


 

  (a)   designate the Eligible Grade Levels, Eligible Employees and Participants in the Plan for each Bonus Period,
 
  (b)   determine the Financial Goals and Performance Goals for each Bonus Period,
 
  (c)   establish Target Bonus percentages for Eligible Employees for each Bonus Period,
 
  (d)   establish Target Bonus percentages for the CEO,
 
  (e)   review and approve Target Bonus percentages for any senior management employees whose compensation is regularly reviewed by it,
 
  (f)   adopt, amend and rescind rules and regulations for the administration of the Plan and for its own acts and proceedings, and
 
  (g)   decide all questions and settle all controversies and disputes which may arise in connection with the Plan.
The Committee may delegate to the CEO such authority and responsibility under the Plan (other than with respect to (d), above) as it may determine to be necessary or desirable. All decisions, determinations and interpretations of the Committee, the CEO or their delegates with respect to the exercise of their respective responsibilities, shall be binding on all parties concerned.
     10. Amendment and Termination. The Board of Directors of the Company, or the Committee, in their absolute discretion, and without notice, may at any time amend or terminate the Plan, provided that no such amendment or termination shall adversely affect the rights of any Participant under any Bonus Award previously paid.
     11. Applicability of Plan Document. The Plan shall be applicable for Bonus Periods beginning on and after May 1, 2006.
