The financial information for the Company (or “JDSU”) as of September 29, 2007 and for the three months ended September 29, 2007 and September 30, 2006 is unaudited, but includes all normal and recurring adjustments that management considers necessary for a fair statement of the financial information set forth herein, in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and rules and regulations of the Securities and Exchange Commission (“SEC”). Accordingly, such information does not include all of the information and footnotes required by U.S. GAAP for annual financial statements. For further information, please refer to the consolidated financial statements and footnotes thereto included in the Company’s Annual Report on Form 10-K for the year ended June 30, 2007.

The balance sheet as of June 30, 2007 has been derived from the audited financial statements at that date but does not include all of the information and footnotes required by U.S. GAAP for complete financial statements. The results for the three months ended September 29, 2007 may not be indicative of results for the year ending June 28, 2008 or any future periods.

As more fully disclosed in “Note 19. Legal Proceedings” on In re JDS Uniphase Corporation Securities Litigation, a jury trial began on October 23, 2007. The trial is currently scheduled to last for nineteen Court days. Although the complaint does not specify the precise amount of damages sought, Plaintiffs have stated in recent court filings that they intend to seek a verdict of more than $20 billion in alleged damages. Plaintiffs’ expert witness on damages has generally testified to that effect in the pending jury trial. While there are many potential outcomes of the pending trial, in the event of a final, non-appealable and enforceable judgment against the Company that is in an amount commensurate with the Plaintiffs’ maximum theory of damages, it would not have sufficient assets to pay such a judgment. The Company believes that the factual allegations and circumstances underlying these securities class actions are without merit.

On September 21, 2006, the Board of Directors approved a 1-for-8 reverse split of the Company’s common stock, following approval by the stockholders on December 1, 2005. The reverse stock split was effective on October 16, 2006, before trading began on October 17, 2006. Fractional shares resulting from the split were rounded down to the next whole number. All shares and per share amounts, including all common stock equivalents (stock options, other equity incentive awards, equity compensation plans, and convertible notes) in the Consolidated Financial Statements and Notes to the Consolidated Statements, have been retroactively adjusted for all periods presented to reflect the reverse stock split.

The Company utilizes a 52-53 week fiscal year ending on the Saturday closest to June 30th.

The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States and include the Company and its wholly-owned subsidiaries. All inter-company accounts and transactions have been eliminated.

For the three months ended September 29, 2007, the Company recorded an adjustment that resulted in additional cost of sales of $0.6 million in its first quarter related to prior quarters. This adjustment had no impact on net loss per share for the three months ended September 29, 2007.

For the three months ended September 30, 2006, the Company recorded adjustments related to inventory and restructuring. The corrections resulted in the Company recording $2.6 million in additional cost of sales and operating expense in its first quarter related to prior quarters. These adjustments resulted in $0.01 additional net loss per share for the three months ended September 30, 2006. Management and the Audit Committee believe that such amounts are not material to previously reported financial statements.

The preparation of the Company’s consolidated financial statements in conformity with U. S. GAAP requires management to make estimates and assumptions that affect the reported amount of assets and liabilities at the date of the financial statements and the reported amount of net revenue and expenses during the period. The Company bases estimates on historical experience and on various assumptions about the future that are believed to be reasonable based on available information. The Company’s reported financial position or results of operations may be materially different under different conditions or when using different estimates and assumptions, particularly with respect to significant accounting policies. In the event that estimates or assumptions prove to differ from actual results, adjustments are made in subsequent periods to reflect more current information.

The Company’s accumulated other comprehensive income (loss) consists of the accumulated net unrealized gains or losses on available-for-sale investments, foreign currency translation adjustments, and pension liability.

The components of comprehensive income (loss), net of tax, were as follows (in millions):

At September 29, 2007 and June 30, 2007, balances for the components of accumulated other comprehensive income (loss) were as follows (in millions):

The following table sets forth the computation of basic and diluted net loss per share (in millions, except per share data):

As the Company incurred net losses for the three months ended September 29, 2007 and September 30, 2006, potential dilutive securities from stock options, employee stock purchase plan (“ESPP”), Full Value Awards, and Zero Coupon Senior Convertible Notes have been excluded from the diluted net loss per share computations as their effect was deemed anti-dilutive.

As of September 29, 2007, contingently issuable shares relating to the 1% Senior Convertible Notes were also excluded in accordance with Emerging Issues Task Force Abstract No. 04-8, “The Effect of Contingently Convertible Debt on Diluted Earnings Per Share” (“EITF 04-8”). These shares, which are represented below as potentially dilutive securities, would be included in the computation of diluted net income per share in periods when the closing price of the Company’s common stock is at least $30.30. Depending on the stock price on the conversion date, up to a maximum of approximately 14.0 million shares, subject to certain adjustments, may be issued upon conversion of the 1% Senior Convertible Notes. In addition, during the first quarter of fiscal 2008, the Company repurchased $75.0 million aggregate principal amount of the Zero Coupon Senior Convertible Notes for $70.3 million in cash. The repurchase and retirement of the notes reduced the number of conversion shares potentially issuable from approximately 9.7 million at June 30, 2007 to approximately 7.8 million at September 29, 2007. For additional information regarding these two notes, see “Note 10. Convertible Debt and Letters of Credit”.

The following table sets forth the weighted average potentially dilutive securities excluded from the computation because their effect would have been anti-dilutive (in millions):

In February 2007, the Financial Accounting Standards Board (“FASB”) issued Statement of Financial Accounting Standards No. 159, “The Fair Value Option for Financial Assets and Financial Liabilities – Including an amendment of FASB No. 115” (“SFAS 159”). SFAS 159 permits companies to choose to measure many financial instruments and certain other items at fair value in order to mitigate volatility in reported earnings caused by measuring related assets and liabilities differently without having to apply complex hedge accounting provisions. SFAS 159 is effective for the Company beginning in fiscal year 2009. The Company is currently assessing the impact of this statement on its consolidated financial statements.

In September 2006, FASB issued Statement of Financial Accounting Standards No. 157, “Fair Value Measurements” (“SFAS 157”), to provide enhanced guidance when using fair value to measure assets and liabilities. SFAS 157 defines fair value, establishes a framework for measuring fair value in GAAP and expands disclosures about fair value measurements. SFAS 157 applies whenever other pronouncements require or permit assets or liabilities to be measured at fair value and, while not requiring new fair value measurements, may change current practices. The Company is currently evaluating the impact SFAS 157 will have on its consolidated financial statements. SFAS 157 is effective for the Company beginning in fiscal year 2009.

The Company has adjusted goodwill by $3.5 million, the amount not recovered under the indemnification claims from the former Acterna security holders.

The activities and balances for allowance for doubtful accounts and allowance for sales returns and other are as follows (in millions):

Inventories are stated at the lower of cost or market, and include material, labor, and manufacturing overhead costs. The components of inventories were as follows (in millions):

During the three months end September 29, 2007 and September 30, 2006, the Company recorded write-downs of inventories of $1.8 million, and $8.2 million, respectively.

The Company also sold previously written-down inventories of $3.7 million and $3.7 million during the three months ended September 29, 2007 and September 30, 2006, respectively. In addition, the Company has an active scrap program and typically disposes of inventory that has been written down through the use of scrap dealers or physical disposal/destruction. During the three months ended September 29, 2007 and September 30, 2006, the Company scrapped $11.7 million, and $1.7 million of fully reserved inventory, respectively.

The inventory write-downs were predominantly the result of changes in forecasted customer demand and technological changes in the Company’s products. The majority of the inventory written down consisted of raw material and finished goods. The major elements of the written down raw material consists of components and items that had not entered into production. The finished goods inventory includes the cost of raw material inputs, labor, and overhead.

The Company operates in markets with relatively few customers and has historically experienced variability in product demand driven by the buying behaviors of these customers. In addition, the Company’s products utilize long-lead time parts which are available from a limited set of vendors. The combined effects of a limited customer base, variability of demand among the customer base and significant long-lead time or single sourced materials has historically contributed to significant inventory write-downs. The Company routinely reviews inventory for usage potential, including fulfilment of customer warranty obligations and spare part requirements. The Company writes down to zero the value of excess and obsolete (“E&O”) inventory that is not expected to be consumed through operations generally within 12 months. Excess is written down to zero value in large part due to the Company’s history of changes in customer demand and inherent product obsolescence concerns.

For any written down inventory items retained, the Company evaluates the future realizable value of inventories and impact on gross margins, taking into consideration product life cycles, technological and product changes, demand visibility and other market conditions. The Company believes its current process for writing down inventory appropriately balances the risk in the marketplace with a fair representation of the realizable value of the Company’s inventory.

The components of property, plant and equipment, net were as follows (in millions):

At September 29, 2007, Property, plant and equipment, net included $27.4 million in land and buildings related to the Santa Rosa sale and leaseback transactions accounted for under the financings method. See “Note 5. Financing Obligation” for more detail.

The components of other non-current liabilities were as follows (in millions):

On August 21, 2007, the Company entered into a sale and lease back of certain buildings and land in Santa Rosa, California. The Company sold approximately 45 acres of land, 13 buildings with approximately 492,000 rentable square feet, a building pad, and parking areas. The Company leased back 7 buildings with approximately 286,000 rentable square feet. The net cash proceeds received from the transaction were $32.2 million. The lease terms range from a five year lease with a one year renewal option to a ten year lease with two five year renewal options.

The Company has an ongoing obligation to remediate the environmental matter required by the North Coast Regional Water Quality Control Board which existed at the time of sale and obtain a no further action letter from the board. Concurrent with the sale and lease back, the Company has issued an irrevocable letter of credit for $3.8 million as security for the remediation of the environmental matter that remains in effect until the issuance of a notice of no further action letter. In addition, the lease agreement for one building included an option to purchase at fair market value, at the end of the lease term. Due to these various forms of continuing involvement the transaction was recorded under the financing method in accordance with Statement of Financial Accounting Standards No. 98 “Accounting for Leases” (“SFAS 98”) and SFAS 66 “Accounting for Sales of Real Estate” (“SFAS 66”).

Accordingly, the value of the buildings and land will remain on the Company’s books and the buildings will continue to be depreciated over their remaining useful lives. The proceeds received have been recorded as a financing obligation and a portion of the lease payments are recorded as a decrease to the financing obligation and a portion is recognized as interest expense. Imputed rental income from the buildings sold but not leased back is recorded as a reduction in the financing obligation.

The guarantee of up to $3.8 million was accounted for in accordance with FASB Interpretation No. 45 “Guarantor’s Accounting and Disclosure Requirement for Guarantees, Including Indirect Guarantees of Indebtedness of Others” (“FIN 45”). The present value of the guarantee approximates the liability of $1.5 million which was included in Other non-current liabilities as of September 29, 2007.

As of September 29, 2007, $0.3 million was included in the Other current liabilities-accrued expenses, and $31.8 million was included in the Other non-current liabilities.

As of September 29 and June 30, 2007, the Company had total long-term investments of $12.3 million and $3.1 million, respectively, primarily consisting of non-marketable cost and equity method investments.

During the three months ended September 29, 2007, the Company did not record any gain or loss on sale of investments.

During the three months ended September 30, 2006, the Company recorded net gain on sale of investments of $0.3 million primarily due to the sale of the remainder of the Company’s investment in MEMSCAP common stock.

The following table presents goodwill allocated to the reportable segments (in millions):

The Company accounts for goodwill in accordance with the provisions of Statement of Financial Accounting Standards No. 142, “Goodwill and Other Intangible Assets” (“SFAS 142”). Accordingly, the goodwill balance is not amortized but is evaluated for impairment annually as well as when circumstances indicate a possible impairment. The latest annual impairment assessment was performed during the fourth quarter of fiscal 2007. There were no events or circumstances during the three months ended September 29, 2007 that indicated a further assessment was necessary.

The goodwill balance is adjusted quarterly to record the effect of currency translation adjustments.

The following tables present details of the Company’s other intangibles (in millions):

During the three months ended September 29, 2007 and September 30, 2006, the Company recorded $18.9 million and $16.3 million, respectively, of amortization expense relating to other intangibles.

The following table presents details of the Company’s long-term debt (in millions):

Based on quoted market prices, as of September 29, 2007 and June 30, 2007, the fair market value of the 1% Senior Convertible Notes was approximately $341.6 million and $347.8 million, respectively, and the fair market value of the Zero Coupon Senior Convertible Notes was approximately $291.1 million and $354.6 million, respectively. Changes in fair market value reflect both the change in the market price of the notes and the impact of the repurchase of $75.0 million aggregate principal amount of Zero Coupon Senior Convertible Notes during the first quarter of fiscal 2008.

On June 5, 2006, the Company completed an offering of $425 million aggregate principal amount of 1% Senior Convertible Notes due 2026. Proceeds from the notes amounted to $415.9 million after issuance costs. The $9.1 million of costs incurred in connection with the issuance of the notes were capitalized and are being amortized to interest expense on a straight-line basis for seven years which approximates the charge using the effective interest method. As of September 29, 2007, the unamortized portion of the issuance costs related to the notes was $6.1 million and was included in “Other current assets” and “Other non-current assets” on the Consolidated Balance Sheets.

On October 31, 2003, the Company completed the sale of $475.0 million aggregate principal amount of Zero Coupon Senior Convertible Notes due in 2010.

During fiscal 2007, the Company repurchased $92.0 million aggregate principal amount of the Notes for $85.0 million in cash. In connection with the repurchase, the Company recognized a gain of $7.0 million, offset by an expense of $0.7 million related to the write-off of unamortized debt issuance costs. The net gain of $6.3 million was recognized in Interest and other income. After giving effect to the repurchase, the total amount of Zero Coupon Senior Convertible Notes outstanding as of June 30, 2007 was $383.0 million.

During the first quarter of fiscal 2008, the Company repurchased an additional $75.0 million aggregate principal amount of the Notes for $70.3 million in cash. In connection with the repurchase, the Company recognized a gain of $4.7 million, offset by an expense of $0.5 million related to the write-off of unamortized debt issuance costs. The net gain of $4.2 million was recognized in Interest and other income. After giving effect to the repurchase, the total amount of Zero Coupon Senior Convertible Notes outstanding as of September 29, 2007 was $308.0 million. The additional repurchase reduced the number of conversion shares potentially issuable in relation to the Zero Coupon Notes by approximately 1.9 million from 9.7 million to 7.8 million.

The $12.7 million of costs incurred in connection with issuance of the notes were capitalized and are being amortized to Interest expense on a straight-line basis over five years. As of September 29, 2007, the remaining unamortized issuance costs related to the outstanding notes was $1.6 million and was included in “Other current assets” and “Other non-current assets” on the Consolidated Balance Sheets.

As of September 29, 2007, the Company had 16 standby letters of credit totalling $15.9 million.

During the third quarter of fiscal 2004, the Company announced completion of the Global Realignment Program (“GRP”), which began in April 2001. That program focused on large-scale site and employee reductions. The Company continues to take advantage of opportunities to further reduce costs through targeted, customer-driven restructuring events intended to consolidate the Company and rationalize the manufacture of its products based on core competencies and cost efficiencies. Restructuring activities initiated prior to December 31, 2002 were recorded in accordance with Emerging Issues Task Force Abstracts No. 94-3 “Liability Recognition for Certain Employee Termination Benefits and Other Costs to Exit an Activity (including Certain Costs Incurred in a Restructuring)” (“EITF Issue 94-3”), and restructuring activities initiated after December 31, 2002 were recorded in accordance with Statement of Financial Accounting Standards No. 146 “Accounting for Costs Associated with Exit or Disposal Activities” (“SFAS 146”) and Statement of Financial Accounting No. 112, “Employees’ Accounting for Post-employment Benefits” (“SFAS 112”). As of September 29, 2007 the Company’s total restructuring accrual was $11.6 million.

Payments related to severance and benefits are expected to be paid off by the first quarter of fiscal 2009.

During the third quarter of fiscal 2007, the Company recorded $(0.1) million in restructuring charges which included $0.5 million for severance and benefits, $0.5 million for manufacturing transfer cost, $(1.0) million for early lease termination buyouts and $(0.1) million to adjust accruals on previously restructured leases. Thirty one employees were notified for termination, 23 in manufacturing, 6 in research and development and 2 in selling, general and administrative functions. All of these 31 notified employees were located in North America. As of September 29, 2007, 30 employee had been terminated. Severance and benefits are scheduled to be paid through the third quarter of fiscal 2008.

During the second quarter of fiscal 2007, the Company recorded $5.5 million in restructuring charges which included $0.8 million for severance and benefits and $4.7 million for manufacturing transfer cost. Eleven employee were notified for termination, 10 in research and development and 1 in selling, general and administrative functions. All of these 11 notified employees were located in North America. As of September 29, 2007, all of these employees had been terminated. Payments related to lease costs are expected to be paid by the first quarter of fiscal 2014.

During the first quarter of fiscal 2007, the Company recorded $5.2 million in restructuring charges which included $0.7 million in expense for severance and benefits, $5.8 million for manufacturing transfer cost and $(1.3) million adjustment to reflect modified lease term on restructured facility. Ten employees were notified for termination, 1 in manufacturing, 4 in research and development and 5 in selling, general and administrative functions. All of these 10 notified employees were located in North America. As of September 29, 2007, all of these employees have been terminated.

During the second quarter of fiscal 2006, the Company recorded $14.9 million in restructuring charges which included $12.8 million in expense for severance and benefits and $2.1 million to adjust accruals on restructured leases. Eight hundred twenty nine employees were notified for termination, 709 in manufacturing, 78 in research and development and 42 in selling, general and administrative functions. Eight hundred twenty four terminated employees were located in North America and 5 in Europe. As of September 29, 2007, 813 of these employees had been terminated. Severance and benefits are scheduled to be paid through the first quarter of fiscal 2009.

The following table summarizes the Company’s restructuring activities (in millions):

The current and non-current portions of the total restructuring accrual are as follows (in millions):

The non-current portion of the restructuring accrual is included as a component of “Other non-current liabilities” in the Company’s Consolidated Balance Sheet. In addition, restructuring expenses are not allocated at the reporting segments level.

On July 13, 2006, the FASB issued Interpretation No. 48 “Accounting for Uncertainty in Income Taxes-An Interpretation of FASB Statement 109” (“FIN 48”). FIN 48 clarifies the accounting for uncertainty in income taxes recognized in an entity’s financial statements in accordance with FASB Statement 109, “Accounting for Income Taxes” and prescribes a recognition threshold and measurement attributes for financial statement disclosure of tax positions taken or expected to be taken on a tax return.

Under FIN 48, the impact of an uncertain income tax position on the income tax return must be recognized at the largest amount that is more-likely-than-not to be sustained upon audit by the relevant taxing authority. An uncertain income tax position will not be recognized if it has less than a 50% likelihood of being sustained. Additionally, FIN 48 provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. FIN 48 is effective for fiscal years beginning after December 15, 2006.

On July 1, 2007, the Company adopted the provisions of FIN 48. As of July 1, 2007, the Company had $76.4 million of liabilities for unrecognized tax benefits. The adoption resulted in a reclassification of certain tax liabilities in the amount of $40.6 million from current to non-current and no significant cumulative impact to retained earnings. As of September 29, 2007, the Company’s liabilities for unrecognized tax benefits totaled $75.2 million and are included in deferred taxes and other non-current tax liabilities, net. The total liabilities for unrecognized tax benefits and decrease for the current period of these liabilities relate primarily to the allocations of revenue and costs among the Company’s global operations. In addition, utilization of the Company’s tax net operating losses may be subject to a substantial annual limitation due to the ownership change limitations provided by the Internal Revenue Code and similar state and foreign provisions. As a result, loss carryforward limitations may result in the expiration or reduced utilization of a portion of the Company’s net operating losses.

Included in the balance of unrecognized tax benefits at July 1, 2007 are $2.9 million of tax benefits that, if recognized, would impact the effective tax rate. Also included in the balance of unrecognized tax benefits at July 1, 2007 are $9.6 million of tax benefits that, if recognized, would result in a decrease to goodwill recorded in purchase business combinations, and $63.9 million of tax benefits that, if recognized, would result in adjustments to the valuation allowance. The impact on net income reflects the liabilities for unrecognized tax benefits net of certain deferred tax assets and the federal tax benefit of state income tax items. One or more of the unrecognized tax benefits could be subject to a valuation allowance if and when recognized in a future period, which could impact the timing of any related effective tax rate benefit. Based on currently available information, the Company does not anticipate a significant change to the total amount of unrecognized tax benefits within the next 12 months.

Upon adoption of FIN 48, the Company’s policy to recognize accrued interest and penalties related to unrecognized tax benefits within the income tax provision did not change. The Company had $34.5 million for the payment of interest and penalties accrued at July 1, 2007. As of September 29, 2007, the Company had accrued $36.9 million for payment of interest and penalties.

The Company and its subsidiaries are subject to income tax in the U.S. as well as numerous state and foreign jurisdictions. The Company’s federal and state income tax returns for fiscal year 2003 through fiscal year 2007 remain open to examination. In addition, the Company files tax returns in multiple foreign taxing jurisdictions with open tax years ranging from fiscal year 2000 to 2007.

The Company recorded an income tax expense of $2.5 million and an income tax benefit of $1.1 million for the three months ended September 29, 2007 and September 30, 2006, respectively.

The income tax expense recorded for the three months ended September 29, 2007, primarily relates to income tax in certain foreign and state jurisdictions based on the Company’s forecasted pre-tax income for the year.

The income tax benefit recorded for the three months ended September 30, 2006 primarily relates to the tax benefit associated with year-to-date losses incurred in certain jurisdictions for which the tax benefit is expected to be realized during the current fiscal year pursuant to FASB Interpretation No. 18, “Accounting for Income Taxes in Interim Periods,” net of a $0.6 million deferred tax expense associated with tax amortization of goodwill for which no financial statement amortization has occurred.

The income tax expense/benefit recorded differs from the expected tax expense/benefit that would be calculated by applying the federal statutory rate to the Company’s loss before income taxes primarily due to the increases in valuation allowance for deferred tax assets attributable to the Company’s domestic and foreign losses from continuing operations.

The Company has recorded deferred tax assets as of September 29, 2007 only to the extent that the Company believes it is more likely than not that these deferred tax assets will be realized. The Company has provided a full valuation allowance on the remainder of its deferred tax assets since the Company believes it is more likely than not that these deferred tax assets will not be realized. The Company intends to maintain the valuation allowance until sufficient positive evidence exists to support reversal of some or all of the allowance. In addition, the occurrence of negative evidence with respect to deferred tax assets which currently have no valuation allowance could result in an increase in the valuation allowance in a future period. The Company’s income tax expense (benefit) recorded in the future will be reduced or increased in the event changes to the valuation allowance are required.

The Company provides stock option plans, employee purchase plans and Full Value Awards to its employees and directors. As of September 29, 2007, the Company had 21.4 million shares of stock options and Full Value Awards issued and outstanding under the Company’s 2005 Acquisition Equity Incentive Plan (the “2005 Plan”), Amended and Restated 2003 Equity Incentive Plan (the “2003 Plan”), and various other plans the Company assumed through acquisitions.

Effective the first day of fiscal 2006, the Company recorded stock-based compensation cost totaling the amount that would have been recognized had the fair value method been applied since the effective date of Financial Accounting Standard No. 123, “Share-Based Payment (Revised 2004)” (“SFAS 123(R)”). Results for prior periods have not been restated.

As required by SFAS 123(R), management has made an estimate of expected forfeitures and is recognizing compensation costs only for those equity awards expected to vest. The impact on the Company’s results of operations of recording stock-based compensation by function for the three month period ended September 29, 2007 and September 30, 2006 was as follows (in millions):

Approximately $1.2 million of stock-based compensation was capitalized as inventory at September 29, 2007.

The exercise price for stock options is equal to the fair value of the underlying stock at the date of grant. Options generally become exercisable over a four-year period and, if not exercised, expire from five to ten years after the date of grant.

On November 14, 2006, the Company’s stockholders approved an amendment and restatement of the 2003 Plan, under which (1) 12,500,000 shares of Common Stock were added to the pool of shares reserved for issuance under the 2003 Plan and (2) all future grants of “Full Value Awards” (as defined below) will reduce the share reserve by one and one-half shares for each share subject to such Awards. Also, during the second quarter of fiscal 2007, the 1996 Non-qualified Stock Option Plan (“1996 Plan”) expired and there were no outstanding options from the 1996 Plan.

The following is a summary of options activities (in millions, except weighted-average exercise price):

As of September 29, 2007, 13.0 million shares of common stock, primarily under the 2003 Equity Incentive Plan, were available for grant.

As of September 29, 2007, $49.6 million of unrecognized stock-based compensation cost related to stock options remains to be amortized. That cost is expected to be recognized over an estimated amortization period of 2.7 years.

The JDS Uniphase Corporation 1998 Employee Stock Purchase Plan, as amended (the “1998 Purchase Plan”), provides eligible employees with the opportunity to acquire an ownership interest in the Company through periodic payroll a 5% discount and a six month look-back period deductions. Of the 50.0 million shares authorized to be issued under the 1998 Purchase Plan, 2.0 million shares remained available for issuance as of September 29, 2007.

The expense related to the Company’s employee stock purchase plan is amortized on a straight-line basis over the relevant subscription period.

As of September 29, 2007, $0.5 million of unrecognized stock-based compensation cost related to ESPP remains to be amortized. That cost is expected to be recognized through the third quarter of fiscal 2008.

“Full Value Awards” are Restricted Stock, Restricted Stock Units, Performance Units, and Performance Shares that are granted with a per share or unit purchase price below 100% of Fair Market Value on the date of grant. They are exercised immediately upon vesting. Prior to the fourth quarter of fiscal 2007, they were granted under the 2005 Plan and 2003 Plan to a limited number of employees. Beginning in the fourth quarter of fiscal 2007, the intent is to use Full Value Awards as the Company’s predominant equity compensation vehicle. These Full Value Awards are performance based, time based, or a combination of performance and time based. These awards are expected to vest over one to five years except with respect to awards with performance conditions, such conditions are achieved on a different timeline. The fair value of the Full Value Awards is based on the closing market price of the Company’s common stock on the date of award.

As of September 29, 2007, $44.1 million of unrecognized stock-based compensation cost related to restricted shares and restricted stock units remains to be amortized. That cost is expected to be recognized over an estimated amortization period of 2.6 years.

A summary of the status of the Company’s nonvested Full Value Awards as of September 29, 2007 and changes during the same period is presented below (amounts in millions, except per share amounts):

Full Value Awards are converted into shares upon vesting. Shares are withheld by the Company for the payment of minimum withholding taxes on the value of the Awards vesting during the period. The shares retained by the Company are treated as treasury shares and are presented on the face of the Balance Sheets.

As a result of the acquisition of Acterna in August 2005, the Company sponsors qualified and non-qualified pension plans for certain employees in the UK and Germany. These plans have been closed to new participants and, except as required by law, are unfunded. For those employees participating in defined benefit plans, benefits are generally based upon years of service and compensation or stated amounts for each year of service. The Company’s policy for funded plans is to make contributions equal to or greater than the requirements prescribed by law in each country. In fiscal 2008, the legally mandated minimum contribution to the Company’s pension plans is expected to be $1.3 million. The funded plan assets consist primarily of managed investments.

The Company accounts for its obligations under these pension plans in accordance with Statement of Financial Accounting Standards No. 87, “Employer’s Accounting for Pensions” (“SFAS 87”), which requires the Company to record its obligation to the participants, as well as the corresponding net periodic cost. The Company determines its obligation to the participants and its net periodic cost principally using actuarial valuations provided by third-party actuaries. The obligation the Company records in its Consolidated Balance Sheets is reflective of the total projected benefit obligation (“PBO”) and the fair value of plan assets.

Effective June 30, 2007, the Company adopted Statement of Financial Accounting Standards No. 158, “Employers’ Accounting for Defined Benefit Pension and Other Postretirement Plans, an amendment of FASB Statements No. 87, 88, 106, and 132(R)” (“SFAS 158”), which requires recognition of the funded status of each defined benefit pension plan and nonpension postretirement benefit plan on the Company’s balance sheet. The impact of SFAS 158 due to previously unrecognized actuarial gains and losses and prior service costs or credits is recognized as a component of Accumulated other comprehensive income (net of tax) in Stockholders’ equity.

The following table presents the components of the net periodic cost for the pension and benefits plans (in millions):

Underlying both the calculation of the PBO and net periodic cost are actuarial valuations. These valuations use participant-specific information such as salary, age, years of service, and assumptions about interest rates, compensation increases and other factors. At a minimum, the Company evaluates its assumptions annually and makes changes as necessary.

The Company expects to incur cash outlays of approximately $6.5 million related to its defined benefit pension plans during fiscal 2008 to make current benefit payments and fund future obligations. As of September 29, 2007, approximately $1.3 million had been incurred. These payments have been estimated based on the same assumptions used to measure the Company’s PBO at June 30, 2007.

As of September 29, 2007 and June 30, 2007, the Company owns approximately 9.9% of BaySpec, a privately held OEM fiber-optics company. The investment is accounted for under the equity method. During the fourth quarter of fiscal 2006, the Company recorded a $1.3 million impairment to reduce the carrying value to zero. BaySpec is both a customer and a supplier of the Company.

As of September 29, 2007 and June 30, 2007, the Company held an investment in Emcore, a publicly traded semiconductor company, valued at $0.4 million and $0.2 million, respectively. Emcore is also a customer of the Company.

During fiscal 2007, Fabrinet, a privately held contract manufacturing company in which the Company has a long-term investment, was both a customer and supplier. The purchases and sales of items between the Company and Fabrinet have been evaluated for accounting under Emerging Issues Task Force Abstract No. 01-09, “Accounting for Consideration Given by a Vendor to a Customer or a Reseller of the Vendor’s Products” (“EITF 01-09”). Based on this evaluation the Company determined that there is an identifiable benefit that was sufficiently separable from the customer’s purchase of the Company’s products and the fair value of that benefit was reasonably estimable in relation to sales to other third parties. As of September 29, 2007 and June 30, 2007, the carrying value of the Company’s investment in Fabrinet was $2.0 million.

The Fuzhou, China legal entities and certain assets of the Ewing and Mountain Lakes, New Jersey facilities were sold to Fabrinet in May 2005. The Company received a note of $10.7 million payable in quarterly installments over four years from Fabrinet and a receivable of $19.0 million for the inventory at Ewing and Mountain Lakes, New Jersey payable in quarterly installments over one year. At September 29, 2007, the related balance receivable from Fabrinet was $3.4 million for the note and zero for the inventory.

During the second quarter of fiscal 2006, the Company announced the transition of products manufactured at its Ottawa, Canada site to other Company facilities and to the facilities of its contract manufacturing partners. During the third quarter of fiscal 2006, the Company entered into an agreement with Fabrinet to sell certain inventories to Fabrinet and to transfer the Ottawa manufacturing operations to the Company’s facilities in Shenzhen, China and St. Etienne, France and to Fabrinet’s facilities in Thailand. The Company agreed to reimburse Fabrinet for the cost associated with on-going production and the wind-down and transfer of production. During the second quarter of fiscal year 2007, the transitions were completed and, as of June 30, 2007, Fabrinet paid off the outstanding balances related to certain production and material transactions. The Company has no obligations to Fabrinet related to severance obligations and arrangement fees. Fabrinet production costs were charged to cost of sales and costs related to the transfer and wind down of production were charged to restructuring. The actual restructuring and non-recurring charges totaled approximately $19.5 million through completion, which includes $4.4 million for severance and retention.

As of September 29, 2007, Fabrinet also owed the Company approximately $4.4 million representing trade accounts receivable relating to product sales.

As of September 29, 2007, the Chairman of JDSU’s Audit Committee was also a member of the Board of Directors of Harmonic, a publicly held company which designs, manufactures and sells systems and software that enable network operators to provide a range of interactive and advanced digital services. Harmonic is a customer of the Company.

As of September 29, 2007 and June 30, 2007, the Chief Executive Officer of JDSU was also a member of the Board of Directors of KLA-Tencor, a publicly held company which provides process control and yield management solutions for the semiconductor manufacturing. KLA-Tencor is a customer of the Company.

Micralyne Inc., a privately held manufacturer of microfabricated and MEMS (Micro-Electro-Mechanical-Systems) based products in which the Company has a long-term investment, is a supplier of the Company. As of September 29, 2007 and June 30, 2007, the carrying value of the Company’s investment in Micralyne was $0.5 million. During the first quarter of fiscal 2007, the Company signed two loan agreements with Micralyne to provide an equipment loan of up to $1.4 million and a working capital line up to $1.6 million. As of September 29, 2007, the balances of these loans are $0.1 million and $1.1 million, respectively.

As of September 29, 2007 and June 30, 2007, the Company held an investment in Santur, a privately held manufacturer of optical components, of which the fair value was written down to zero in the third quarter of fiscal 2006. Santur is both a customer and supplier of the Company.

As of September 29, 2007 and June 30, 2007, Sifam Fibre Optics, a privately held company in which the Company previously had a long-term investment, was a supplier of the Company. On May 4, 2007, the Company sold its 19.9% equity investment in Sifam Fibre Optics Limited for $1.9 million and recognized a gain of $0.7 million. As of September 29, 2007, the Company has no remaining investment in Sifam.

Transactions and balances with the Company’s related parties were as follows (in millions):

The Company has been subject to a Dutch wage tax audit for calendar years 1999, 2000, and 2001, and a Texas franchise tax audit related to allocated taxable surplus capital for Texas report years 2001, 2002, and 2003. While the Company believes that it is reasonably possible that one or both of these audits may result in additional tax liabilities, based on currently available information, the Company believes the ultimate outcome of these audits will not have a material adverse effect on the Company’s financial position, cash flows or overall trends in results of operations. There is the possibility of a material adverse effect on the Company’s financial position, cash flows or overall trends in results of operations for the period in which these matters are ultimately resolved, if they are resolved unfavorably, or in the period in which an unfavorable outcome becomes probable. The range of the potential total tax liability related to these matters is estimated to be from zero to $46.2 million, plus interest and penalties.

The Company evaluates its reportable segments in accordance with Statement of Financial Accounting Standards No. 131, “Disclosures about Segments of an Enterprise and Related Information” (“SFAS 131”) and the FASB’s Emerging Issues Task Force Abstracts No. 04-10, “Determining Whether to Aggregate Segments That Do Not Meet the Quantitative Thresholds” (“EITF No. 04-10”). The Company’s Chief Executive Officer, Kevin J. Kennedy, is the Company’s Chief Operating Decision Maker (“CODM”) pursuant to SFAS 131. The CODM allocates resources to the segments based on their business prospects, competitive factors, net revenue and operating results.

The Company is a leading provider of communications test and measurement solutions and optical products for telecommunications service providers, cable operators, and network equipment manufacturers. Furthermore, it is a leading provider of innovative optical solutions for medical/environmental instrumentation, semiconductor processing, display, brand authentication, aerospace, defense and decorative applications. The major segments the Company serves are:

The Optical Communications business segment provides components, modules, subsystems and solutions used by communications equipment providers for telecommunications and enterprise data communications. These products enable the transmission of video, audio and text data over high-capacity fiber optic cables. These products include transmitters, receivers, amplifiers, ROADMS, optical transceivers, multiplexers and demultiplexers, switches, optical performance monitors and couplers, splitters and circulators.

The Communications Test and Measurement business segment provides instruments, service assurance systems and services to enable the design, deployment, and maintenance of communication equipment and networks, as well as ensure the quality of services delivered to the end customer. These products and services provide solutions that accelerate the deployment of new services and lower operating expenses while improving performance and reliability. Included in the product portfolio are test tools and platforms for optical transport networks, DSL services, data networks, cable networks, digital video broadcast, and fiber characterization services.

The Advanced Optical Technologies business segment provides inventive optical solutions for security and decorative applications and thin-film coatings for a range of public and private sector markets. These products enhance and modify the behavior of light utilizing its reflection, absorption and transmission properties to achieve specific effects such as high reflectivity, anti-glare and spectral filtering. Specific product applications include computer-driven projectors, intelligent lighting systems, photocopiers, facsimile machines, scanners, security products and decorative surface treatments.

The Commercial Lasers business unit provides components and subsystems used in a wide variety of OEM applications. This broad portfolio addresses the needs of our customers in markets and applications such as biotechnology, materials processing, semiconductor, graphics and imaging, remote sensing, and laser marking. These products include industrial diode lasers, fiber lasers, gas lasers, solid-state lasers, and photonic power delivery systems.

The accounting policies of the reportable segments are the same as those described in the Company’s Annual Report on Form 10-K for the year ended June 30, 2007. The Company evaluates segment performance based on operating income (loss) excluding infrequent or unusual items.

The amounts shown as Corporate consist of certain unallocated corporate-level operating expenses. In addition, the Company does not allocate restructuring charges, income taxes, or non-operating income and expenses to its segments.

The Company from time to time enters into certain types of contracts that contingently require the Company to indemnify parties against third-party claims. These contracts primarily relate to: (i) divestiture agreements, under which the Company may provide customary indemnifications to purchasers of the Company’s businesses or assets; (ii) certain real estate leases, under which the Company may be required to indemnify property owners for environmental and other liabilities, and other claims arising from the Company’s use of the applicable premises; and (iii) certain agreements with the Company’s officers, directors and employees, under which the Company may be required to indemnify such persons for liabilities arising out of their employment relationship.

The terms of such obligations vary. Generally, a maximum obligation is not explicitly stated. Because the obligated amounts of these types of agreements often are not explicitly stated, the overall maximum amount of the obligations cannot be reasonably estimated. Historically, the Company has not been obligated to make significant payments for these obligations, and no liabilities have been recorded for these obligations on its balance sheet as of September 29, 2007 and June 30, 2007.

In general, the Company offers a three-month to one-year warranty for most of its products. For certain products, the Company provides a limited three to seven-year warranty. The Company provides reserves for the estimated costs of product warranties at the time revenue is recognized. The Company estimates the costs of its warranty obligations based on its historical experience of known product failure rates, use of materials to repair or replace defective products and service delivery costs incurred in correcting product failures. In addition, from time to time, specific warranty accruals may be made if unforeseen technical problems arise with specific products. The Company periodically assesses the adequacy of its recorded warranty liabilities and adjusts the amounts as necessary.

The following table presents the changes in the Company’s warranty reserve (in millions):

Litigation under the federal securities laws has been pending against the Company and certain former and current officers and directors since March 27, 2002. On July 26, 2002, the Northern District of California consolidated all the securities actions then filed in or transferred to that court under the title In re JDS Uniphase Corporation Securities Litigation, Master File No. C-02-1486 CW, and appointed the Connecticut Retirement Plans and Trust Funds as Lead Plaintiff.

The complaint in In re JDS Uniphase Corporation Securities Litigation purports to be brought on behalf of a class consisting of those who acquired the Company’s securities from October 28, 1999, through July 26, 2001, as well as on behalf of subclasses consisting of those who acquired the Company’s common stock pursuant to its acquisitions of OCLI, E-TEK, and SDL. Plaintiffs allege that Defendants made material misstatements and omissions concerning demand for the company’s products, improperly recognized revenue, overstated the value of inventory, and failed to timely write down goodwill. The complaint alleges various violations of the federal securities laws, specifically Sections 10(b), 14(a), 20(a), and 20A of the Securities Exchange Act of 1934 and Sections 11, 12(a)(2), and 15 of the Securities Act of 1933. In January 2005, the Court denied the motion to dismiss claims against the Company, Jozef Straus, Anthony R. Muller, and Charles Abbe, and granted in part and denied in part the motion to dismiss claims against Kevin Kalkhoven. Defendants subsequently filed answers denying liability for the claims asserted against them. On December 21, 2005, the Court granted Plaintiffs’ motion for class certification.

Fact and expert discovery in In re JDS Uniphase Corporation Securities Litigation is complete. Each party has noticed and taken depositions of experts and both party and non-party witnesses. On August 24, 2007, the Court granted in part and denied in part Defendants’ motions for summary judgment. On September 25, 2007, the Court denied Plaintiffs’ motion for partial summary judgment.

A jury trial began on October 23, 2007. The trial is currently scheduled to last for nineteen Court days. Although the complaint does not specify the precise amount of damages sought, Plaintiffs have stated in recent court filings that they intend to seek a verdict of more than $20 billion in alleged damages. Plaintiffs’ expert witness on damages has generally testified to that effect in the pending jury trial. While there are many potential outcomes of the pending trial, in the event of a final, non-appealable and enforceable judgment against the Company that is in an amount commensurate with the Plaintiffs’ maximum theory of damages, it would not have sufficient assets to pay such a judgment.

A related securities case, Zelman v. JDS Uniphase Corp., No. C-02-4656 CW (N.D. Cal.), is purportedly brought on behalf of a class of purchasers of debt securities that were allegedly linked to the price of JDSU’s common stock. The Zelman complaint alleges that the debt securities were issued by an investment bank during the period from March 6, 2001 through July 26, 2001. The complaint names the Company and several of its former officers and directors as Defendants, alleges violations of the federal securities laws, specifically Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, and Rule 10b-5, and seeks unspecified damages. On August 26, 2005, Defendants answered the complaint. On November 16, 2005, the Court granted Plaintiffs’ motion for class certification, which Defendants had not opposed. Fact discovery in the Zelman action is substantially complete. A case management conference is scheduled for November 13, 2007. No trial date has been set.

On January 29, 2007, another securities action was filed in the Northern District of California against the Company, Dr. Straus, and Messrs. Muller, Abbe, and Kalkhoven. That action, Central States Southeast and Southwest Areas Pension Fund v. JDS Uniphase Corp., No. 07-0584 CW, is based on allegations similar to those made in In re JDS Uniphase Corporation Securities Litigation and asserts claims under Sections 10(b), 14(a), and 20(a) of the Securities Exchange Act of 1934 and Sections 11, 12(a)(2), and 15 of the Securities Act of 1933. The Central State complaint seeks unspecified damages on behalf of a pension fund that purportedly purchased Company securities between October 28, 1999, and July 26, 2001, and elected to opt-out of participation in In re JDS Uniphase Corporation Securities Litigation. On February 14, 2007, the Central States action was deemed related to In re JDS Uniphase Corporation Securities Litigation and was assigned to Judge Claudia Wilken. A case management conference in the Central States action is scheduled for October 23, 2008, and trial is set to begin on January 26, 2009.

Derivative actions purporting to be brought on the Company’s behalf have been filed in state and federal courts against several of the Company’s current and former officers and directors based on the same events alleged in the securities litigation. The complaint in Corwin v. Kaplan, No. C-02-2020 CW (N.D. Cal.), asserts state law claims for breach of fiduciary duty, misappropriation of confidential information, waste of corporate assets, indemnification, and insider trading. The complaint seeks unspecified damages. In January 2005, the Court stayed the action pending resolution of In re JDS Uniphase Corporation Securities Litigation. A case management conference is scheduled for November 13, 2007.

In the California state derivative action, In re JDS Uniphase Corporation Derivative Litigation, Master File No. CV806911 (Santa Clara Super. Ct.), the complaint asserts claims for breach of fiduciary duty, waste of corporate assets, abuse of control, gross mismanagement, unjust enrichment, and constructive fraud purportedly on behalf of the Company and certain of its current and former officers and directors. The complaint also asserts claims for violation of California Corporations Code Sections 25402 and 25502.5 against defendants who sold the Company’s stock and asserts claims for breach of contract, professional negligence, and negligent misrepresentation against the Company’s former auditor, Ernst & Young LLP. The complaint seeks unspecified damages. On February 13, 2007, the Court granted the parties’ request to stay the California derivative action and the shareholder inspection demand action brought by the plaintiff in the California derivative action. The defendants’ updated responses to the California derivative complaint are due on November 21, 2007, and a hearing on those responses is scheduled for January 18, 2008. In the shareholder inspection demand action, a case management conference is scheduled for December 7, 2007.

No activity has occurred in Cromas v. Straus, Civil Action No. 19580 (Del. Ch. Ct.), the Delaware derivative action, since our last quarterly filing as of March 31, 2007.

Plaintiffs purporting to represent the former shareholders of OCLI and SDL have filed suit against the former directors of those companies, asserting that they breached their fiduciary duties in connection with the events alleged in the securities litigation against the Company. Plaintiffs in the OCLI action, Pang v. Dwight, No. 02-231989 (Sonoma Super. Ct.), purport to represent a class of former shareholders of OCLI who exchanged their OCLI shares for JDSU shares when JDSU acquired OCLI. The complaint names the former directors of OCLI as Defendants, asserts causes of action for breach of fiduciary duty and breach of the duty of candor, and seeks unspecified damages. On March 4, 2007, the parties signed a memorandum of understanding regarding a settlement of the OCLI action. The Plaintiffs in the SDL action, Cook v. Scifres, Master File No. CV814824 (Santa Clara Super. Ct.), purport to represent a class of former shareholders of SDL who exchanged their SDL shares for JDSU shares when the Company acquired SDL. Plaintiffs filed an amended complaint on November 20, 2006. The complaint names the former directors of SDL as Defendants, asserts causes of action for breach of fiduciary duty and breach of the duty of disclosure, and seeks unspecified damages. On March 6, 2007, the Court overruled Defendants’ demurrer to that complaint. A case management conference is scheduled for January 25, 2008. Limited discovery in the SDL action has occurred. No trial date has been set in either the OCLI or SDL action.

A consolidated action entitled In re JDS Uniphase Corporation ERISA Litigation, Case No. C-03-4743 WWS (MEJ), is pending in the District Court for the Northern District of California against the Company, certain of its former and current officers and directors, and certain other current and former JDSU employees on behalf of a purported class of participants in the 401(k) Plans of the Company and Optical Coating Laboratory, Inc. and the Plans themselves. On October 31, 2005, Plaintiffs filed an amended complaint. The amended complaint alleges that Defendants violated the Employee Retirement Income Security Act by breaching their fiduciary duties to the Plans and the Plans’ participants. The amended complaint alleges a purported class period from February 4, 2000, to the present and seeks an unspecified amount of damages, restitution, a constructive trust, and other equitable remedies. Certain individual Defendants’ motion to dismiss portions of the amended complaint was granted with prejudice on June 15, 2006.

Plaintiffs filed a second amended complaint on June 30, 2006. Defendants answered the complaint on July 6, 2006, and JDSU asserted counterclaims for breach of contract. The Court dismissed those counterclaims on September 11, 2006. On December 15, 2006, defendants moved for summary judgment on the ground that the named plaintiffs lacked standing. On the same day, plaintiffs moved for class certification. On April 24, 2007, the Court denied defendants’ motion for summary judgment as to plaintiff Douglas Pettit, deferred ruling on the motion for summary judgment as to plaintiff Eric Carey, and deferred ruling on plaintiffs’ motion for class certification. Both sides have taken discovery. Trial is set to begin on September 22, 2008.

The Company believes that the factual allegations and circumstances underlying these securities actions, derivative actions, the OCLI and SDL class actions, and the ERISA class actions are without merit. The expense of defending these lawsuits has been costly, will continue to be costly, and could be quite significant and may not be covered by our insurance policies. The defense of these lawsuits could also result in continued diversion of our management’s time and attention away from business operations which could prove to be time consuming and disruptive to normal business operations. An unfavorable outcome or settlement of this litigation (such as, for example an adverse judgment in the In re JDS Uniphase Corporation Securities Litigation trial which commenced on October 23, 2007) could have a material adverse effect on the Company’s financial position, liquidity or results of operations, credit ratings, and ability to access capital markets and comply with existing debt obligations.

The Company is also subject to a variety of other claims and suits that arise from time to time in the ordinary course of our business. While management currently believes that resolving claims against the Company, individually or in aggregate, will not have a material adverse impact on its financial position, results of operations or statement of cash flows, these matters are subject to inherent uncertainties and management’s view of these matters may change in the future. Were an unfavorable final outcome to occur, there exists the possibility of a material adverse impact on the Company’s financial position, results of operations or statement of cash flows for the period in which the effect becomes reasonably estimable.

During October and November 2007, the Company repurchased an additional $47.0 million aggregate principal amount of the Zero Coupon Senior Convertible Notes for $44.6 million in cash. This additional repurchase reduced the total amount of Zero Coupon Notes outstanding to $261.0 million and reduced the number of conversion shares potentially issuable in relation to the Zero Coupon Notes by approximately 1.2 million shares to approximately 6.6 million shares. In connection with the repurchase, the Company will recognize a gain of approximately $2.1 million, net of the write-off of debt issuance costs, in the second quarter of fiscal year 2008.

In February 2007, the Financial Accounting Standards Board (“FASB”) issued Statement of Financial Accounting Standards No. 159, “The Fair Value Option for Financial Assets and Financial Liabilities – Including an amendment of FASB No. 115” (“SFAS 159”). SFAS 159 permits companies to choose to measure many financial instruments and certain other items at fair value in order to mitigate volatility in reported earnings caused by measuring related assets and liabilities differently without having to apply complex hedge accounting provisions. SFAS 159 is effective beginning fiscal year 2009. We are currently assessing the impact of this statement on our consolidated financial statements.

In September 2006, FASB issued Statement of Financial Accounting Standards No. 157, “Fair Value Measurements” (“SFAS 157”), to provide enhanced guidance when using fair value to measure assets and liabilities. SFAS 157 defines fair value, establishes a framework for measuring fair value in GAAP and expands disclosures about fair value measurements. SFAS 157 applies whenever other pronouncements require or permit assets or liabilities to be measured at fair value and, while not requiring new fair value measurements, may change current practices. SFAS 157 is effective beginning fiscal year 2009. We are currently evaluating the impact SFAS 157 will have on our consolidated financial statements.

For a description of the critical accounting policies that affect our more significant judgments and estimates used in the preparation of our consolidated financial statements, refer to our Annual Report on Form 10-K filed with the Securities and Exchange Commission (“SEC”). On July 1, 2007, we adopted the provisions of FIN48.

For the three months ended September 29, 2007, we recorded an adjustment that resulted in additional cost of sales of $0.6 million in its first quarter related to prior quarters. This adjustment had no impact to net loss per share for the three months ended September 29, 2007.

For the three months ended September 30, 2006, we recorded adjustments related to inventory reserve, accounting for inventory variances and restructuring. The corrections resulted in an additional $2.6 million of cost of sales and operating expense in the first quarter related to prior quarters. These adjustments resulted in $0.01 additional net loss per share for the three months ended September 30, 2006. Management and the Audit Committee believe that such amounts are not material to previously reported financial statements.

The results of operations for the current period are not necessarily indicative of results to be expected for future years. The following table summarizes selected Consolidated Statement of Operations items (in millions, except for percentages):

Net revenue in the first quarter of fiscal 2008 increased 12%, or $38.6 million, to $356.7 million from $318.1 million in the same quarter a year ago. The increase is primarily due to an increased demand for our Communications Test and Measurement and Advanced Optical Technologies products. Communications Test and Measurement business increased due to strong gains in the field service business and lab and production business, coupled with acquisition related gains. Advanced Optical technologies business increased due to demand for our Document Authentication products, Visual products, and increased demand in aerospace and defense. Revenue growth is also the result of recent acquisitions of Innocor and Casabyte. The increase in net revenue was partially offset by a decline in the circuit pack business in the Optical Communications group, and reduced solid state lasers sales in the Commercial Laser group.

Going forward, we expect to continue to encounter a number of industry and market structural risks and uncertainties that will limit our business climate and market visibility, and consequently, our ability to predict future revenue, profitability and general financial performance, and that could create quarter over quarter variability in one or more of our financial measures. These structural risks and uncertainties include: (a) strong pricing pressures, particularly within our Optical Communications markets, due to, among other things, a highly concentrated customer base, increasing Asian competition, excess device manufacturing capacity within the optical communications industry and a general commoditization trend for many of our products; (b) high product mix variability, particularly in our Optical Communications products, which causes revenue variability, as well as gross profit variability due to, among other things, factory utilization fluctuations and inventory and supply chain management complexities; (c) seasonal buying patterns within our Communications Test and Measurement customers, which causes significant seasonal revenue variation within this high gross margin business unit; and (d) continuing service provider business model uncertainty, which causes demand, revenue and profitability measure unpredictability at each level of the communications industry. Moreover, the current trend of communications industry consolidations is expected to continue, directly affecting our Optical Communication’s and Communications Test and Measurement’s customer base and adding additional risk and uncertainty to our financial and business predictability.

Our program of North American assembly manufacturing transitions are entering their final phases, but until completed, these activities will continue to present additional supply chain and product delivery disruption risks, yield and quality concerns and increased cost risks. These risks, while expected to diminish over the next several quarters, also currently limit our ability to predict future revenue, profitability and general financial performance.

Gross profit in the first quarter of fiscal 2008 increased 36%, or $35.7 million, to $133.7 million from $98.0 million in the same quarter a year ago. The increase is primarily due to gross profit increase in our Communications Test and Measurement segment, mostly from an increase in margins in the field services business and better product mix, with higher margin products representing a higher share of revenues, coupled with the acquisition of Casabyte and Innocor. Gross profit also increased in the Advanced Optical Technologies group due to cost containment efforts and improved manufacturing efficiencies and yield improvements. This increase in gross profit was partially offset by small increase in amortization expense of acquired developed technologies, purchase accounting adjustments recognized in fiscal 2006 and 2007. Gross profit excluding amortization expense of acquired developed technologies in the first quarter of fiscal 2008 increased 35%, or $37.8 million, to $145.7 million from $107.9 million in the first quarter of fiscal 2007.

As discussed in more detail under “Net Revenue” above, we sell products in certain markets that are consolidating, undergoing product, architectural and business model transitions, have high customer concentrations, are highly competitive (increasingly due to Asia-based competition), are price sensitive and are affected by customer seasonal and mix variant buying patterns. These factors along with our continuing ongoing product and manufacturing transitions, supplier constraints and factory utilization and execution issues, can and will result in pressure on, and quarterly variability in, our gross profit. In addition to the risks and uncertainties discussed under “Net Revenue” above, we face additional risks and uncertainties, associated with new product introductions that could impair future gross profits. New product programs and introductions, which due to their large scale restricted field testing and lack of production manufacturers with their increased complexity, have incurred and are expected to continue to incur relatively higher start-up costs and increased yield and product quality risk. Issues associated with some of these products have negatively impacted and could continue to negatively impact our gross profit.

Research and Development (“R&D”) and Selling, General and Administrative (“SG&A”)

R&D and SG&A expenses for the first quarter of fiscal 2008 increased 19%, or $23.8 million to $146.8 million, from $123.0 million in the same period a year ago. The increase is primarily due to increased selling expense on higher bookings, the inclusion of Casabyte, Test-Um, Innocor and Picolight acquisitions, and increased investment in new platforms and products.

We believe that investment in R&D is critical to attaining our strategic objectives. Historically, we have devoted significant engineering resources to assist with production, quality and delivery challenges which have had some negative impact on our new product development activities. Despite our continued efforts to reduce total operating expenses, there can be no assurance that our R&D expenses will continue to remain at the current level. In addition, there can be no assurance that such expenditures will be successful or that improved processes or commercial products, at acceptable volumes and pricing, will result from our investment in R&D.

We intend to continue to aggressively address our SG&A expenses and reduce these expenses as and when opportunities arise. We have in the recent past experienced, and expect to continue to experience in the future, certain non-core expenses, such as litigation and dispute related settlements and accruals, which could increase our SG&A expenses, and impair our profitability expectations, in any particular quarter. We are also increasing SG&A expenses in the near term to complete the integration of recent acquisitions, particularly with respect to business infrastructure and systems matters. None of these non-core expenses, however, is expected to have a material adverse impact on our financial condition. There can be no assurance that our SG&A expense will decline in the future or that, more importantly, we will develop a cost structure (including our SG&A expense), which will lead to profitability under current and expected revenue levels.

Amortization of other intangibles for the three months ended September 29, 2007 increased 16%, or $2.6 million, to $18.9 million from $16.3 million in the same quarter a year ago. The increase is primarily due to the increase in our intangible assets subject to amortization as a result of our acquisitions of Test-Um in the fourth quarter of fiscal 2006, and Casabyte, Innocor and Picolight in fiscal 2007.

The other intangibles balance is adjusted quarterly to record the effect of currency translation adjustments.

During the three months ended September 29, 2007 and September 30, 2006, we recorded $0.4 million and $0.1 million, respectively, of reductions of the carrying value of other long-lived assets.

During the three months ended September 29, 2007, we did not record any asset impairment charges. During the three months ended September 30, 2006, we recorded an impairment charge of $0.7 million for certain assets related to Rochester Minnesota facility in accordance with SFAS 144.

During the three months ended September 29, 2007 and September 30, 2006, we did not record any asset impairment charges.

During the three months ended September 29, 2007, we recorded a loss of $0.4 million for the sale and disposal of assets. During the three months ended September 30, 2006, we recorded a gain of $0.6 million for the sale and disposal of assets.

During the three months ended September 29, 2007 and September 30, 2006, we did not record any asset impairment charges.

During the third quarter of fiscal 2004, we announced completion of the Global Realignment Program (“GRP”), which began in April 2001. That program focused on large-scale site and employee reductions. We continue to take advantage of opportunities to further reduce costs through targeted, customer-driven restructuring events intended to consolidate and rationalize the manufacture of our products based on core competencies and cost efficiencies. See “Note 11. Restructuring” for more detail.

During the first quarter of fiscal 2008, we recorded $1.1 million in restructuring charges which included $1.1 million for severance and benefits, $0.2 million for manufacturing transfer cost, and $(0.2) million to adjust accruals on previously restructured leases. Forty one employees were notified for termination, 27 in manufacturing, 4 in research and development and 10 in selling, general and administrative functions. Of these notified employees, 18 were located in North America and 23 were located in Asia. As of September 29, 2007, 23 of these employees have been terminated. Payments related to severance and benefits are expected to be paid off by the second quarter of fiscal 2008.

During the fourth quarter of fiscal 2007, we recorded $4.1 million in restructuring charges which included $3.6 million for severance and benefits, $0.2 million for manufacturing transfer cost, and $0.3 million to adjust accruals on previously restructured leases. One hundred and eighty nine employees were notified for termination, 158 in manufacturing, 21 in research and development and 10 in selling, general and administrative functions. Of these notified employees, 185 were located in North America and 4 were located in Asia. As of September 29, 2007, 108 of these employees have been terminated. Payments related to severance and benefits are expected to be paid off by the first quarter of fiscal 2009.

During the third quarter of fiscal 2007, we recorded $(0.1) million in restructuring charges which included $0.5 million for severance and benefits, $0.5 million for manufacturing transfer cost, $(1.0) million for early lease termination buyouts and $(0.1) million to adjust accruals on previously restructured leases. Thirty one employees were notified for termination, 23 in manufacturing, 6 in research and development and 2 in selling, general and administrative functions. All of these 31 notified employees were located in North America. As of September 29, 2007, 30 employees had been terminated. Severance and benefits are scheduled to be paid through the third quarter of fiscal 2008.

During the second quarter of fiscal 2007, we recorded $5.5 million in restructuring charges which included $0.8 million for severance and benefits and $4.7 million for manufacturing transfer cost. Eleven employees were notified for termination, 10 in research and development and 1 in selling, general and administrative functions. All of these 11 notified employees were located in North America. As of September 29, 2007, all of these employees had been terminated. Payments related to lease costs are expected to be paid by the first quarter of fiscal 2014.

During the first quarter of fiscal 2007, we recorded $5.2 million in restructuring charges which included $0.7 million in expense for severance and benefits, $5.8 million for manufacturing transfer cost and $(1.3) million adjustment to reflect modified lease term on restructured facility. Ten employees were notified for termination, 1 in manufacturing, 4 in research and development and 5 in selling, general and administrative functions. All of these 10 notified employees were located in North America. As of September 29, 2007, all of these employees have been terminated.

During the second quarter of fiscal 2006, we recorded $14.9 million in restructuring charges which included $12.8 million in expense for severance and benefits and $2.1 million to adjust accruals on restructured leases. Eight hundred twenty nine employees were notified for termination, 709 in manufacturing, 78 in research and development and 42 in selling, general and administrative functions. Eight hundred twenty four terminated employees were located in North America and 5 in Europe. As of September 29, 2007, 813 of these employees had been terminated. Severance and benefits are scheduled to be paid through the first quarter of fiscal 2009.

Our ability to generate sublease income, as well as our ability to terminate lease obligations at the amounts estimated, is highly dependent upon the economic conditions, particularly commercial real estate market conditions in certain geographies, at the time we negotiate the lease termination and sublease arrangements with third parties as well as the performances by such third parties of their respective obligations. While the amount we have accrued represents the best estimate of the remaining obligations we expect to incur in connection with these plans, estimates are subject to change. Routine adjustments are required and may be required in the future as conditions and facts change through the implementation period. Our restructuring obligations are net of sublease income or lease settlement estimates of approximately $5.5 million. If adverse macroeconomic conditions continue, particularly as they pertain to the commercial real estate market, or if, for any reason, tenants under subleases fail to perform their obligations, we may be required to reduce estimated future sublease income and adjust the estimated amounts of future settlement agreements, and accordingly, increase estimated cost to exit certain facilities. Amounts related to the lease expense, net of anticipated sublease proceeds, will be paid over the respective lease terms through fiscal 2014.

The actions under the GRP and other restructuring actions may not be successful in achieving the expected cost reductions or other benefits, may be insufficient to align our operations with customer demand and the changes affecting our industry, or may be more costly or extensive than currently anticipated. Even if the restructuring activities are successful and meet our current cost reduction goals, our revenue must continue to increase substantially in the future for us to be profitable.

During the three months ended September 29, 2007, Interest and other income was $19.3 million, a decrease of $0.5 million compared to the same period a year ago. The first quarter of fiscal 2008 results included a net gain of $4.2 million from the repurchase of $75.0 million aggregate principal amount of the Zero Coupon Senior Convertible Notes and an increase in interest income of $1.2 million primarily due to improved yields on cash and short term investments. In the three months ended September 30, 2006, $5.1 million income was related to the settlement of a held-to-maturity security.

During the three months ended September 29, 2007, interest expense was $2.2 million, an increase of $0.3 million compared to the same period a year ago. The increase was primarily due to interest charges of $0.2 million related to a capital lease of Santa Rosa real estate.

We did not record any gain on sale of investment during the three months ended September 29, 2007. The net gain of $0.3 million during the three months ended September 30, 2006 was primarily due to the sale of the remainder of our investments in MEMSCAP common stock.

On July 1, 2007, we adopted the provisions of FIN 48. As of July 1, 2007, we had $76.4 million of liabilities for unrecognized tax benefits. The adoption resulted in a reclassification of certain tax liabilities in the amount of $40.6 million from current to non-current and no significant cumulative impact to retained earnings. As of September 29, 2007, our liabilities for unrecognized tax benefits totaled $75.2 million and are included in deferred taxes and other non-current tax liabilities, net. The total liabilities for unrecognized tax benefits and decrease for the current period of these liabilities relate primarily to the allocations of revenue and costs among our global operations. In addition, utilization of our tax net operating losses may be subject to a substantial annual limitation due to the ownership change limitations provided by the Internal Revenue Code and similar state and foreign provisions. As a result, loss carryforward limitations may result in the expiration or reduced utilization of a portion of our net operating losses.

Included in the balance of unrecognized tax benefits at July 1, 2007 are $2.9 million of tax benefits that, if recognized, would impact the effective tax rate. Also included in the balance of unrecognized tax benefits at July 1, 2007 are $9.6 million of tax benefits that, if recognized, would result in a decrease to goodwill recorded in purchase business combinations, and $63.9 million of tax benefits that, if recognized, would result in adjustments to the valuation allowance. The impact on net income reflects the liabilities for unrecognized tax benefits net of certain deferred tax assets and the federal tax benefit of state income tax items. One or more of the unrecognized tax benefits could be subject to a valuation allowance if and when recognized in a future period, which could impact the timing of any related effective tax rate benefit. Based on currently available information, we do not anticipate a significant change to the total amount of unrecognized tax benefits within the next 12 months.

Upon adoption of FIN 48, our policy to recognize accrued interest and penalties related to unrecognized tax benefits within the income tax provision did not change. We had $34.5 million for the payment of interest and penalties accrued at July 1, 2007. As of September 29, 2007, we had accrued $36.9 million for payment of interest and penalties.

We are subject to income tax in the U.S. as well as numerous state and foreign jurisdictions. Our federal and state income tax returns for fiscal year 2003 through fiscal year 2007 remain open to examination. In addition, we file tax returns in multiple foreign taxing jurisdictions with open tax years ranging from fiscal year 2000 to 2007.

We recorded an income tax expense of $2.5 million and an income tax benefit of $1.1 million for the three months ended September 29, 2007 and September 30, 2006, respectively.

The income tax expense recorded for the three months ended September 29, 2007 primarily relates to income tax in certain foreign and state jurisdictions based on our forecasted pre-tax income for the year.

The income tax expense/benefit recorded differs from the expected tax expense/benefit that would be calculated by applying the federal statutory rate to our loss before income taxes primarily due to the increases in valuation allowance for deferred tax assets attributable to our domestic and foreign losses from continuing operations.

We have recorded deferred tax assets as of September 29, 2007 only to the extent that we believe it is more likely than not that these deferred tax assets will be realized. We have provided a full valuation allowance on the remainder of its deferred tax assets since we believe\ it is more likely than not that these deferred tax assets will not be realized. We intend to maintain the valuation allowance until sufficient positive evidence exists to support reversal of some or all of the allowance. In addition, the occurrence of negative evidence with respect to deferred tax assets which currently have no valuation allowance could result in an increase in the valuation allowance in a future period. Our income tax expense (benefit) recorded in the future will be reduced or increased in the event changes to the valuation allowance are required.

The decrease in operating income for Optical Communications during the three month period ended September 29, 2007 over the same quarter a year ago is due to a reduction in revenue in the circuit pack business coupled with increasing in operating expenses related to new acquisition costs.

The increase in operating income for Communications Test & Measurement during the three month period ended September 29, 2007 over the same quarter a year ago reflects a strong broadband deployment trend, partially offset by increased operating expense from sales commissions on higher bookings and the continued efforts to increase our R&D investment level to invest in new products and technologies.

The increase in operating income for Advanced Optical Technologies during the three month period ended September 29, 2007 over the same quarter a year ago reflects an increased demand for our Document Authentication, Visual, and Infrared products, a more profitable product mix, and flat operating expense spending.

The decrease in operating income for Lasers during the three months ended September 29, 2007 over the same periods a year ago reflects a decrease in shipments of Solid State Lasers as demand for these products declined. This was coupled with increased costs of production costs and operating expenses related to increased investment in product development and marketing.

As of September 29, 2007, we had a combined balance of cash, cash equivalents, short-term investments and restricted cash of $1,127.4 million, a decrease of $15.3 million from June 30, 2007. Cash and cash equivalents increased by $13.8 million in the three month period ended September 29, 2007, primarily due to net proceeds from sales and maturities of investments of $33.2 million, cash generated by operating activities of $36.2 million, the receipt of financing obligation of $32.2 million and cash inflows of $5.0 million from the exercise of stock options and the issuance of stock under employee stock plans, offset by outflows from the purchases of property, plant and equipment of $9.0 million, purchases of long term investments of $9.0 million and the use of $70.3 million to repurchase a portion of the Zero Coupon Senior Convertible Notes.

Cash provided by operating activities was $36.2 million during the three months ended September 29, 2007, resulting from our net loss adjusted for non-cash items such as depreciation, amortization and various gains and losses of $35.9 million, and changes in operating assets and liabilities that provided $0.3 million related primarily to a decrease in accounts receivable of $13.0 million, offset by a decrease in accounts payable of $10.9 million.

Operating activities used $16.3 million during the three months ended September 30, 2006, resulting from our net loss adjusted for non-cash items such as depreciation, amortization and various gains and losses of $15.5 million, offset by changes in operating assets and liabilities that used $31.8 million.

Cash provided by investing activities was $9.0 million during the three months ended September 29, 2007, primarily related to net proceeds from sales and maturities of investments of $33.2 million, offset by purchases of property, plant and equipment of $9.0 million, purchases of long term investments of $9.0 million and additions to restricted cash of $6.3 million.

Cash used by investing activities was $84.1 million during the three months ended September 30, 2006, primarily related to net purchases of short-term investments of $67.2 million and purchases of property, plant and equipment of $23.3 million, offset by $5.1 million proceeds from a convertible note settlement.

Our investments of surplus cash are made in accordance with an investment policy approved by the Audit Committee of our Board of Directors. In general, our investment policy requires that securities purchased and held be rated A-1/P-1, A/A2 or better. No security may have an effective maturity that exceeds 37 months, and the average duration of our holdings may not exceed 18 months. At any time, no more than 10% of the investment portfolio may be concentrated in a single issuer other than the U.S. government or U.S. agencies. Our investments in debt securities and marketable equity securities are primarily classified as available-for-sale investments or trading assets and are recorded at fair value. The cost of securities sold is based on the specific identification method. Unrealized gains and losses on available-for-sale investments are reported as a separate component of stockholders’ equity. We did not hold any investments in auction rate securities, mortgage backed securities, collateralized demand obligations, or variable rate demand notes at September 29, 2007.

Financing activities for the three months ended September 29, 2007 used cash of $33.1 million, primarily related to the use of $70.3 million to repurchase a portion of Zero Coupon Senior Convertible Notes, offset by the receipt of financing obligation of $32.2 million and the issuance of common stock under our employee stock option programs and employee stock plans of $5.0 million.

Financing activities for the three months ended September 30, 2006 provided cash of $5.0 million, primarily resulting from the issuance of common stock under our employee stock option programs and employee stock plans.

As more fully disclosed in “Note 19. Legal Proceedings”, a jury trial began on October 23, 2007 on In re JDS Uniphase Corporation Securities Litigation. The trial is currently scheduled to last for nineteen Court days. Although the complaint does not specify the precise amount of damages sought, Plaintiffs have stated in recent court filings that they intend to seek a verdict of more than $20 billion in alleged damages. Plaintiffs’ expert witness on damages has generally testified to that effect in the pending jury trial. While there are many potential outcomes of the pending trial, in the event of a final, non-appealable and

enforceable judgment against the Company that is in an amount commensurate with the Plaintiffs’ maximum theory of damages, it would not have sufficient assets to pay such a judgment. The Company believes that the factual allegations and circumstances underlying these securities class actions are without merit.

For additional disclosures on obligations relating to the securities class action lawsuits, FIN 48 tax issues, and the lease relating to our Santa Rosa facility, see “Note 19. Legal Proceedings”, “Note 12. Income Tax”, and “Note 5. Financing Obligation”, respectively.

We do not have any off-balance sheet arrangements, as such term is defined in rules promulgated by the SEC, that have or are reasonably likely to have a current or future effect on our financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources that are material to investors.

As part of our strategy, we are committed to the ongoing evaluation of strategic opportunities and, where appropriate, the acquisition of additional products, technologies or businesses that are complementary to, or broaden the markets for our products. We believe we strengthened our business model by expanding our addressable market, customer base, and expertise, diversifying our product portfolio, and fortifying our core businesses through acquisition as well as through organic initiatives.

In May 2007, we completed the acquisition of Innocor, a provider of broadband test solutions for network equipment manufacturers. The merger strengthened JDSU’s position in the North American lab and production markets and helped grow our business in the EMEA and APAC regions. Innocor is included in our Communications Test and Measurement segment.

In May 2007, we completed the acquisition of Picolight, a designer and manufacturer of optical pluggable transceivers. By acquiring Picolight, we strengthened our position in high-growth pluggable optics for the enterprise market and added an established, vertically integrated manufacturing model. Picolight is included in our Optical Communications segment.

In January 2007, we completed the acquisition of Casabyte, a provider of service quality monitoring solutions for mobile network operations. By acquiring Casabyte, we accelerated our service assurance growth by capitalizing on a number of key assets, including Casabyte’s wireless service quality solutions expertise, technology and established customer relationships. We also plan to leverage our global direct sales organization and other distribution channels to increase Casabyte’s penetration into international markets. Casabyte is included in our Communications Test and Measurement segment.

Please refer to “Note 3. Mergers and Acquisitions” of our Notes to Consolidated Financial Statements for more information.

Our stock option and Full Value Award program are a broad-based, long-term retention program that is intended to attract and retain employees and align stockholder and employee interests. As of September 29, 2007, we have available for issuance 13.0 million shares of common stock for grant primarily under our Amended and Restated 2003 Equity Incentive Plan (the “2003 Plan”). The exercise price for the options is equal to the fair market value of the underlying stock at the date of grant. Options generally become exercisable over a four-year period and, if not exercised, expire from five to ten years post grant date. Majority of our employees participate in our stock option program. “Full Value Awards” are Restricted Stock, Restricted Stock Units, Performance Units and Performance Shares that are granted with a per share or unit purchase price below 100% of Fair Market Value on the date of grant. These Full Value Awards are performance based, time based, or a combination of performance and time based and are expected to vest over one to five years except with respect to awards with performance conditions, such conditions are achieved on a different timeline. The fair value of the Full Value Awards is based on the closing market price of our common stock on the date of award. Beginning in the fourth quarter of fiscal 2007, the intent is to use Full Value Awards as our predominant equity compensation vehicle. See “Note 13. Stock-Based Compensation” for more detail.

As a result of acquiring Acterna in August 2005, we sponsor pension plans for certain past and present employees in the UK and Germany. JDSU also is responsible for the non-pension postretirement benefit obligation of a previously acquired subsidiary. These plans have been closed to new participants and, except as required by law, have not been funded. Statement of Financial Accounting Standards No. 158 “Employer’s Accounting for Defined Pension and Other Retirement Plans, an amendment of FASB Statements No. 87, 88, 106, and 132(R)” (“SFAS 158”) requires the recognition of the funded status of the pension plans and non-pension postretirement benefit plans (retirement-related benefit plans) as an asset or a liability in the Consolidated Balance Sheet, the recognition of changes in that funded status in the year in which they occur through the Gains and (losses) not affecting retained earnings, net of tax, and the recognition of previously unrecognized gains/(losses), prior service costs/(credits) and transition assets as a component of Accumulated gains and (losses) not affecting retained earnings in the Consolidated Statement of Stockholders’ Equity. The funded status of a retirement plan is the difference between the projected benefit obligation and the fair value of its plan assets. The projected benefit obligation is the actuarial present value of all benefits attributed by the plan’s benefit formula to employee service. At September 29, 2007, our pension plans were under funded by $90.9 million since the projected benefit obligation exceeded the fair value of its plan assets. Similarly, we had accrued $0.8 million related to our non-pension postretirement benefit plan. Because the plans have received limited funding in the past, we anticipate future annual contributions to the plans will approximate estimated future benefit payments. These payments have been estimated based on the same actuarial assumptions used to measure our projected benefit obligation and currently are forecasted to range between $4.9 million and $5.9 million per annum.

A key actuarial assumption is the discount rate. Changes in the discount rate impact the interest cost component of the net periodic benefit cost calculation and, due to the fact that the accumulated benefit obligation (“ABO”) is calculated on a net present value basis, changes in the discount rate will also impact the current ABO. Decreases in the discount rate will generally increase pre-tax cost, recognized expense and the ABO. Increases in the discount rate tend to have the opposite effect. In estimating the expected return on plan assets, we considers the historical returns on plan assets, adjusted for forward-looking considerations, inflation assumptions and the impact of the active management of the plan’s invested assets. Reflecting the relatively long-term nature of the plan’s obligations, approximately 67% of the plan’s assets were invested in a diversified portfolio of bonds, with the balance primarily invested in equities. While it is not possible to accurately predict future rate movements, we believe our current assumptions are conservative. Please refer to “Note 14. Employee Benefit Plans” for further discussion.

We periodically review the stage of completion and likelihood of success of each of the IPR&D projects. The nature of the efforts required to develop the IPR&D projects into commercially viable products principally relates to the completion of all planning, designing, prototyping, verification and testing activities that are necessary to establish that the products can be produced to meet their design specifications, including functions, features and technical performance requirements. The current status of our significant IPR&D projects from acquisitions is as follows:

Picolight was acquired in May 2007, and at the time of acquisition was in the process of developing transceivers. We have incurred post-acquisition costs of approximately $1.9 million to date and estimate that additional investment of approximately $3.6 million in research and development will be required. The project is expected to complete in the fourth quarter of fiscal 2008.

Lightwave was acquired in May 2005, and at the time of acquisition was in the process of developing multiple diode pumped solid state laser products. We have incurred post-acquisition costs of $7.7 million to date and estimate that additional investment of approximately $1.6 million in research and development will be required. The project is expected to complete in the third quarter of fiscal year 2008.

We believe that our existing cash balances and investments will be sufficient to meet our liquidity and capital spending requirements at least through the next 12 months. However, possible investments in or acquisitions of complementary businesses, products or technologies may require the use of additional cash or financing prior to such time. We have in recent periods consumed, and we may continue to consume, portions of our cash reserves to fund our operations. The amounts consumed to date, together with the amounts currently anticipated to be spent, are not expected to materially impair our financial condition. However, we may need to expend additional, currently unanticipated, cash reserves to fund our operations. Our liquidity could be negatively affected by a decline in demand for our products, which are subject to rapid technological changes, or a reduction of capital expenditures by telecommunications carriers.

We are exposed to various market risks, including changes in foreign currency exchange rates and interest rates. Derivatives and other financial instruments are used to mitigate exposures subject to market risk. We do not enter into derivatives or other financial instruments for trading or speculative purposes.

We utilize foreign exchange forward contracts and other instruments, including option contracts, to hedge foreign currency risk associated with foreign currency denominated assets and liabilities, primarily short-term certain intercompany receivables and payables. Our foreign exchange forward contracts and other instruments are accounted for as derivatives whereby the fair value of the contracts are reflected as other current assets or other current liabilities and the associated gains and losses are reflected in Interest and other income (loss) in the Consolidated Statements of Operations. Our hedging programs reduce, but do not eliminate, the impact of currency exchange rate movements. The gains and losses on those derivatives are expected to be offset by re-measurement gains and losses on the foreign currency denominated assets and liabilities.

Forward contracts, most with a term of less than 60 days, were transacted near month end and therefore, the fair value of the contracts is approximately zero. The following table provides information about our foreign currency forward and option contracts outstanding as of September 29, 2007.

The counterparties to these hedging transactions are creditworthy multinational banks. The risk of counterparty nonperformance associated with these contracts is not considered to be material. Notwithstanding our efforts to mitigate some foreign exchange risks, we do not hedge all of our foreign currency exposures, and there can be no assurances that our mitigating activities related to the exposures that we do hedge will adequately protect us against the risks associated with foreign currency fluctuations.

We maintain an investment portfolio in a variety of financial instruments, including, but not limited to, U.S. government and agency bonds, corporate obligations, money market funds, asset-backed securities, and other investment-grade securities. The majority of these investments pay a fixed rate of interest. The securities in the investment portfolio are subject to market price risk due to changes in interest rates, perceived issuer creditworthiness, marketability, and other factors. We also own minority equity investments in publicly-traded companies, the values of which are subject to market price volatility. These investments are generally classified as available-for-sale and, consequently, are recorded on our Consolidated Balance Sheets at fair value with unrealized gains or losses reported as a separate component of stockholders’ equity. We did not hold any investments in auction rate securities, mortgage backed securities, collateralized demand obligations, or variable rate demand notes at September 29, 2007.

Investments in both fixed-rate and floating-rate interest earning instruments carry a degree of interest rate risk. The fair market values of our fixed-rate securities decline if interest rates rise, while floating-rate securities may produce less income than expected if interest rates fall. Due in part to these factors, our future investment income may be less than expectations because of changes in interest rates or we may suffer losses in principal if forced to sell securities that have experienced a decline in market value because of changes in interest rates.

The fair market value of the Zero Coupon Senior Convertible Notes and the 1% Senior Convertible Notes is subject to interest rate and market price risk due to the convertible feature of the notes and other factors. Generally the fair market value of fixed interest rate debt will increase as interest rates fall and decrease as interest rates rise. The fair market value of the notes may also increase as the market price of JDSU stock rises and decrease as the market price of the stock falls. Interest rate and market value changes affect the fair market value of the notes but do not impact our financial position, cash flows or results of operations. Based on quoted market prices, as of September 29 and June 30, 2007, the fair market values of the Zero Coupon Senior Convertible Notes were approximately $291.1 million and $354.6 million and the fair market values of the 1% Senior Convertible Notes were $341.6 million and $347.8 million, respectively. Changes in fair market value reflect both the change in the market price of the notes and the impact of the partial repurchase of the Zero Coupon Senior Convertible Notes. For additional information, see “Note 10. Convertible Debt and Letters of Credit”.

Disclosure Controls and Procedures: The Company’s management, with the participation of the Company’s principal executive officer and principal financial officer, has evaluated the effectiveness of the Company’s disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) as of the end of the period covered by this report. Based on such evaluation, the Company’s Chief Executive Officer and Chief Financial Officer have concluded that, as of the end of such period, the Company’s disclosure controls and procedures were effective.

Internal Control Over Financial Reporting: There have not been any changes in the Company’s internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the most recent fiscal quarter that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

No activity has occurred in Cromas v. Straus, Civil Action No. 19580 (Del. Ch. Ct.), the Delaware derivative action, since our last quarterly filing as of March 31, 2007.

The Company believes that the factual allegations and circumstances underlying these securities actions, derivative actions, the OCLI and SDL class actions, and the ERISA class actions are without merit. The expense of defending these lawsuits has been costly, will continue to be costly, and could be quite significant and may not be covered by our insurance policies. The defense of these lawsuits (such as, for example an adverse judgment in the In re JDS Uniphase Corporation Securities Litigation trial which commenced on October 23, 2007) could also result in continued diversion of our management’s time and attention away from business operations which could prove to be time consuming and disruptive to normal business operations. An unfavorable outcome or settlement of this litigation could have a material adverse effect on the Company’s financial position, liquidity or results of operations, credit ratings, and ability to access capital markets and comply with existing debt obligations.

Other than with respect to the risk factors below, there have been no material changes from the risk factors previously disclosed in Part I, Item 1A of our Annual Report on Form 10-K for the fiscal year ended June 30, 2007. The three risk factors below were disclosed on the Form 10-K and have been updated to provide an update on certain litigation risks, as well as investment and outstanding convertible notes statistics as of September 29, 2007.

We have had numerous lawsuits filed against us asserting various claims, including securities and ERISA class actions and stockholder derivative actions. The results of complex legal proceedings are difficult to predict. Moreover, many of the complaints filed against us do not specify the amount of damages that plaintiffs seek, and we therefore are unable to estimate the possible range of damages that might be incurred should these lawsuits be resolved against us. While we are unable to estimate the potential damages arising from such lawsuits, certain of them assert types of claims that, if resolved against us, could give rise to substantial damages. Thus, an unfavorable outcome or settlement of one or more of these lawsuits could have a material adverse effect on our financial condition, liquidity and results of operations. In particular, the securities class actions discussed in Item 1, “Legal Proceedings,” contained in Part II of this report, claim damages that exceed the total current assets of the Company and thus an unfavorable outcome or settlement of one or more of these securities class action lawsuits (such as, for example an adverse judgment in the In re JDS Uniphase Corporation Securities Litigation trial which commenced on October 23, 2007) could have a substantial material adverse effect on our financial condition, liquidity and results of operations, credit ratings, and ability to access capital markets and comply with existing debt obligations. Even if these lawsuits are not resolved against us, the uncertainty and

expense associated with unresolved lawsuits could seriously harm our business, financial condition and reputation. Litigation is costly, time-consuming and disruptive to normal business operations. The costs of defending these lawsuits, particularly the securities class actions and stockholder derivative actions, have been significant, will continue to be costly and may not be covered by our insurance policies. The defense of these lawsuits could also result in continued diversion of our management’s time and attention away from business operations, which could harm our business. For additional information regarding certain of the lawsuits in which we are involved, see Item 1, “Legal Proceedings,” contained in Part II of this report.

If we fail to manage our exposure to worldwide financial and securities markets successfully, our operating results and financial statements could be materially impacted.

We are exposed to financial market risks, including changes in interest rates, foreign currency exchange rates and prices of marketable equity and fixed-income securities. The primary objective of most of our investment activities is to preserve principal while at the same time maximizing yields without significantly increasing risk. To achieve this objective, a majority of our marketable investments are investment grade, liquid, short-term fixed-income securities and money market instruments denominated in U.S. dollars. A substantial portion of our net revenue, expense and capital purchasing activities are transacted in U.S. dollars. However, some of these activities are conducted in other currencies, primarily Canadian, European and Asian currencies. To protect against reductions in value and the volatility of future cash flows caused by changes in foreign exchange rates, we may enter into foreign currency forward contracts or other hedging instruments. We do not use derivative financial instruments for speculative or trading purposes. The contracts and other hedging instruments are intended to reduce, but not eliminate, the impact of foreign currency exchange rate movements. We do not hedge all of our foreign currency risk and have no plans to do so in the foreseeable future. Because we do not hedge all of our foreign currency exposures and because there is no assurance that our foreign currency hedging activities will be successful, foreign currency gains and losses could have a material adverse effect on our financial results and cash flows.

As of September 30, 2007, we held investments in other public and private companies and had limited funds invested in private venture funds. Such investments represented approximately $12.7 million on our Consolidated Balance Sheets at September 30, 2007. In addition to our investments in public companies, we have in the past made, and expect to continue to make, investments in privately held companies as well as venture capital investments for strategic and commercial purposes. In the past some of the private companies in which we held investments have ceased doing business and have either liquidated or have entered into bankruptcy proceedings. If the carrying value of our investments exceeds the fair value, and the decline in fair value is deemed to be other-than-temporary, we will be required to further write down the value of our investments, which could materially harm our results of operations or financial condition.

We sold $475 million of senior convertible notes in 2003 and $425 million of senior convertible notes in 2006, which may cause our reported earnings per share to be more volatile because of the conversion contingency features of these notes.

We issued $475 million of indebtedness in October 2003 and $425 million of indebtedness in May and June, 2006 in the form of senior convertible notes. As of September 30, 2007, $733.0 million of these notes remained outstanding. The issuance of these notes substantially increased our principal payment obligations and we may not have enough cash to repay the notes when due. The degree to which we are leveraged could materially and adversely affect our ability to successfully obtain financing for working capital, acquisitions or other purposes and could make us more vulnerable to industry downturns and competitive pressures. In addition, the holders of those notes are entitled to convert those notes into shares of our common stock or a combination of cash and shares of common stock under certain circumstances which would cause dilution to our existing stockholders and lower our reported per share earnings.

Pursuant to the requirements of the Securities Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned thereunto duly authorized.
