| Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
| Fiscal Years | Fiscal Years The Company utilizes a 52-53-week fiscal year ending on the Saturday closest to June 30th. The Company’s 2019 , 2018 and 2017 fiscal years were 52-week fiscal years ending on June 29, 2019 , June 30, 2018 and July 1, 2017 , respectively. |
| Principles of Consolidation | Principles of Consolidation The Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and include the Company and its wholly-owned subsidiaries. All inter-company accounts and transactions have been eliminated. |
| Use of Estimates | Use of Estimates The preparation of the Company’s Consolidated Financial Statements in conformity with U.S. GAAP requires management to make estimates and assumptions that effect the reported amount of assets and liabilities at the date of the financial statements, the reported amount of net revenues and expenses and the disclosure of commitments and contingencies during the reporting periods. Estimates are based on historical factors, current circumstances and the experience and judgment of management. Under changed conditions the Company’s reported financial positions or results of operations may be materially impacted when using different estimates and assumptions, particularly with respect to significant accounting policies. If estimates or assumptions differ from actual results, subsequent periods are adjusted to reflect more readily available information. |
| Cash and Cash Equivalents | Cash and Cash Equivalents The Company considers highly liquid instruments such as treasury bills, commercial paper and other money market instruments with original maturities of 90 days or less at the time of purchase to be cash equivalents. Cash equivalents also include certain term deposits with financial institutions that the Company can liquidate with 30 days’ advance notice without incurring penalties. |
| Restricted Cash | Restricted Cash At June 29, 2019 and June 30, 2018 , the Company’s short-term restricted cash balances were $3.5 million and $7.3 million , respectively. The Company’s long-term restricted cash balances were $5.4 million and $5.6 million as of June 29, 2019 and June 30, 2018 |
| Investments | Investments The Company’s investments are primarily investments in debt securities which are classified as available-for-sale investments or trading securities, recorded at fair value. The cost of securities sold is based on the specific identified method. Unrealized gains and losses resulting from changes in fair value on available-for-sale investments, net of tax, are reported within accumulated other comprehensive (loss). The Company periodically reviews these debt investments for impairment. If a debt security’s fair value is below amortized cost and the Company either intends to sell the security or it is more likely than not that the Company will be required to sell the security before its anticipated recovery, the Company records an other-than-temporary impairment charge to current earnings for the entire amount of the impairment; if a debt security’s fair value is below amortized cost and the Company does not expect to recover the entire amortized cost of the security, the Company separates the other-than-temporary impairment into the portion of the loss related to credit factors, or the credit loss portion, and the portion of the loss that is not related to credit factors, or the non-credit loss portion. The credit loss portion is the difference between the amortized cost of the security and the Company’s best estimate of the present value of the cash flows expected to be collected from the debt security. The non-credit loss portion is the residual amount of the other-than-temporary impairment. The credit loss portion is recorded as a charge to income (loss), and the non-credit loss portion is recorded as a separate component of other comprehensive (loss) income. The Company’s short-term investments are classified as current assets, include certain securities with stated maturities of longer than twelve months, are highly liquid and available to support its current operations. |
| Fair Value of Financial Instruments | Fair Value of Financial Instruments For assets and liabilities measured at fair value, fair value is the price to sell an asset or paid to transfer a liability in an orderly transaction between market participants as of the measurement date. When determining fair value, the Company considers the principle or most advantageous market in which it would transact, and the Company considers assumptions that market participants would use when pricing asset or liabilities. The three levels of inputs that may be used to measure fair value are: • Level 1 : Quoted market prices for identical instruments in active markets for identical assets or liabilities. • Level 2 : Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities, quoted prices in less active markets or model-derived valuations. All significant inputs used in the Company’s valuations, such as discounted cash flows, are observable or derived from or corroborated with observable market data for substantially the full term of the assets or liabilities. • Level 3 : Unobservable inputs to the valuation methodology that are significant to the measurement of the fair value of assets or liabilities. Level 3 inputs and valuation models are monitored and reviewed by the Company to help ensure the fair value measurements are reasonable and consistent with market experience in similar asset classes. Due to the short period of time to maturity, the Company approximates the fair values of its cash equivalents, accounts receivable, accounts payable and deferred compensation liability. Estimates of fair value of fixed-income securities are based on third party, market-based pricing sources which the Company believes to be reliable. These estimates represent the third parties’ good faith opinion as to what a buyer in the marketplace would pay for a security in a current sale. For instruments that are not actively traded, estimates may be based on current treasury yields adjusted by an estimated market credit spread for the specific instrument. The fair value of the Company’s 1.75% Senior Convertible Notes due 2023 and 1.00% |
| Inventories | Inventories The Company’s inventory is valued at standard cost, which approximates actual cost computed on a first-in, first-out basis, not in excess of net realizable value. On a quarterly basis, the Company assesses the value of its inventory and writes down those inventories determined to be obsolete or in excess of its forecasted usage to their market value. The Company’s estimates of realizable value are based upon management analysis and assumptions including, but not limited to, forecasted sales levels by product, expected product life cycle, product development plans and future demand requirements. The Company’s product line management personnel play a key role in its excess review process by providing updated sales forecasts, managing product transitions and working with manufacturing to minimize excess inventory. Differences between actual market conditions and customer demand to the Company’s forecasts, may create favorable or unfavorable inventory positions, and may result in additional inventory write-downs or higher than expected income from operations. The Company’s inventory amounts include material, labor, and manufacturing overhead costs. |
| Property, Plant and Equipment | Property, Plant and Equipment Property, plant and equipment are stated at cost, net of accumulated depreciation. Depreciation is computed using a straight-line method, over the estimated useful lives of the assets: building and improvements 10 to 50 years, machinery and equipment 2 to 20 years, furniture, fixtures, software and office equipment 2 to 5 years. Leasehold improvements are amortized on the straight-line method over the lesser of the estimated useful lives of the asset or the initial lease term. Demonstration units are amortized on the straight-line method and are Company products used for demonstration purposes for existing and prospective customers. These assets are generally not intended to be sold and have an estimated useful life of 3 to 5 years. Costs related to software acquired, developed or modified solely to meet the Company’s internal requirements and for which there are no substantive plans to market are capitalized in accordance with the authoritative guidance on accounting for the costs of computer software developed or obtained for internal use. Only costs incurred after the preliminary planning stage of the project and after management has authorized and committed funds to the project are eligible for capitalization. Costs capitalized for computer software developed or obtained for internal use are included in Property, plant and equipment, net on the Company’s Consolidated Balance Sheets. |
| Goodwill | Goodwill Goodwill represents the excess of the purchase price paid, over the net fair value of assets acquired and liabilities assumed, to purchase an enterprise or asset. The Company tests goodwill for impairment at the reporting unit level at least annually, during the fourth quarter of each fiscal year, or more frequently if events or changes in circumstances indicate that the asset may be impaired. The accounting guidance provides the Company with the option to perform a qualitative assessment to determine whether further impairment testing is necessary. The qualitative assessment considers events and circumstances that might indicate that a reporting unit’s fair value is less than its carry amount. These events and circumstances include, macro-economic conditions, such as a significant adverse change in the Company’s operating environment, industry or market considerations; entity-specific events such as increasing costs, declining financial performance, or loss of key personnel; or other events, such as the sale of a reporting unit, adverse regulatory developments or a sustained decrease in the Company’s stock price. If it is determined, as a result of the qualitative assessment, that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, a quantitative test is required. Otherwise, no further testing is required. |
| Intangible Assets | Intangible Assets |
| Long-lived Assets | Long-lived Assets Long-lived assets, including intangible assets and property and equipment, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of any asset or asset group may not be recoverable. Such an evaluation is performed at the lowest identifiable level of cash flows independent of other assets. An impairment loss would be recognized when estimated undiscounted future cash flows generated from the assets are less than their carrying amount. Measurement of an impairment loss would be based on the excess of the carrying amount of the asset or asset group over its estimated fair value. Estimates of future cash flow require significant judgment based on anticipated future and operating results, which are subject to variability and change. |
| Pension and Other Postretirement Benefits | Pension and Other Postretirement Benefits The funded status of the Company’s retirement-related benefit plans is recognized on the Consolidated Balance Sheets. The funded status is measured as the difference between the fair value of plan assets and the benefit obligation at fiscal year end, the measurement date. For defined benefit pension plans, the benefit obligation is the projected benefit obligation (“PBO”) and for the non-pension postretirement benefit plan the benefit obligation is the accumulated postretirement benefit obligation (“APBO”). The PBO represents the actuarial present value of benefits expected to be paid upon its employee’s retirement. The APBO represents the actuarial present value of postretirement benefits attributed to employee services already rendered. Unfunded or partially funded plans, with the benefit obligation exceeding the fair value of plan assets, are aggregated and recorded as a retirement and non-pension postretirement benefit obligation equal to this excess. The current portion of the retirement-related benefit obligation represents the actuarial present value of benefits payable in the next 12 months in excess of the fair value of plan assets, measured on a plan-by-plan basis. This liability is recorded in other current liabilities in the Consolidated Balance Sheets. Net periodic pension cost is recorded in the Consolidated Statements of Operations and includes service cost, interest cost, expected return on plan assets, amortization of prior service cost (credit), and (gains) losses previously recognized as a component of accumulated other comprehensive (loss) income. Service cost represents the actuarial present value of participant benefits attributed to services rendered by employees in the current year. Interest cost represents the time value of money cost associated with the passage of time. (Gains) losses arise as a result of differences between actual experience and assumptions or as a result of changes in actuarial assumptions. Prior service cost (credit) represents the cost of benefit improvements attributable to prior service granted in plan amendments. (Gains) losses and prior service cost (credit) not recognized as a component of net periodic pension cost in the Consolidated Statements of Operations as they arise are recognized as a component of accumulated other comprehensive (loss) income on the Consolidated Balance Sheets, net of tax. Those (gains) losses and prior service cost (credit) are subsequently recognized as a component of net periodic pension cost pursuant to the recognition and amortization provisions of the authoritative guidance. The measurement of the benefit obligation and net periodic pension cost is based on the Company’s estimates and actuarial valuations provided by third-party actuaries and are approved by management. These valuations reflect the terms of the plans and use participant-specific information such as compensation, age and years of service, as well as certain assumptions, including estimates of discount rates, expected return on plan assets, rate of compensation increases and mortality rates. The Company evaluates these assumptions periodically but not less than annually. In estimating the expected return on plan assets, the Company considers historical returns on plan assets, diversification of plan investments, adjusted for forward-looking considerations, inflation assumptions and the impact of the active management of the plan’s invested assets. The Company measures its benefit obligation and plan assets using the month-end date of June 30, which is closest to the Company’s fiscal year-end. |
| Concentration of Credit and Other Risks | Concentration of Credit and Other Risks Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents, short-term investments, restricted cash, trade receivables and foreign currency forward contracts. The Company’s cash and cash equivalents and short-term investments are held in safekeeping by large, creditworthy financial institutions. The Company invests its excess cash primarily in U.S. government and agency bonds securities, corporate securities, money market funds, asset-backed securities, other investment-grade securities and certificates of deposit. The Company has established guidelines relative to credit ratings, diversification and maturities that seek to maintain the safety and liquidity of these investments. The Company’s foreign exchange derivative instruments expose the Company to credit risk to the extent that the counterparties may be unable to meet the terms of the agreements. The Company seeks to mitigate such risk by limiting its counterparties to major financial institutions and by spreading such risk across several major financial institutions. Potential risk of loss with any one counterparty resulting from such risk is monitored by the Company on an ongoing basis. The Company maintains an allowance for doubtful accounts for estimated losses resulting from the inability of its customers to make required payments. When the Company becomes aware that a specific customer is unable to meet its financial obligations, the Company records a specific allowance to reflect the level of credit risk in the customer’s outstanding receivable balance. In addition, the Company records additional allowances based on certain percentages of aged receivable balances. These percentages consider a variety of factors including, but not limited to, current economic trends, historical payment and bad debt write-off experience. The Company classifies bad debt expenses as SG&A expense. The Company is not able to predict changes in the financial stability of its customers. Any material changes in the financial status of any one customer or a group of customers could have a material adverse effect on the Company’s results of operations and financial condition. Although such losses have been within management’s expectations to date, there can be no assurance that such allowances will continue to be adequate. The Company has significant trade receivables concentrated in the telecommunications industry. While the Company’s allowance for doubtful accounts balance is based on historical loss experience along with anticipated economic trends, unanticipated financial instability in the telecommunications industry could lead to higher than anticipated losses. As of June 29, 2019 and June 30, 2018 , no customer represented 10% or more of the Company’s total accounts receivable, net. During fiscal 2019 , 2018 and 2017 , one customer generated 10% or more of total net revenues. Refer to “ Note 18. Operating Segments and Geographic Information ” for more information. The Company relies on a limited number of suppliers and contract manufacturers for a number of key components and sub-assemblies contained in the Company’s products. The Company generally uses a rolling twelve -month forecast based on anticipated product orders, customer forecasts, product order history and backlog to determine its materials requirements for any one period. Lead times for the parts and components that the Company orders may vary significantly and depend on factors such as the specific supplier, contract terms and demand for a component at any given time. If the forecast does not meet actual demand, the Company may have surplus or dearth of some materials and components, as well as excess inventory purchase commitments. The Company could experience reduced or delayed product shipments or incur additional inventory write-downs and cancellation charges or penalties, which may result in increased costs and have a material adverse impact on the Company’s results of operations. |
| Foreign Currency Forward Contracts | Foreign Currency Forward Contracts The Company conducts its business and sells its products to customers primarily in North America, Europe, Asia and South America. In the normal course of business, the Company’s financial position is routinely subject to market risks associated with foreign currency rate fluctuations due to balance sheet positions in foreign currencies. The Company evaluates foreign exchange risks and utilizes foreign currency forward contracts to reduce such risks, hedging the gains or losses generated by the re-measurement of significant foreign currency denominated monetary assets and liabilities. The fair value of these contracts is reflected as other current assets or liabilities and the change in fair value of these foreign currency forward contracts is recorded as gain or loss in the Company’s Consolidated Statements of Operations as a component of interest and other income, net. The gain or loss from the change in fair value of these foreign currency forward contracts largely offsets the change in fair value of the foreign currency denominated monetary assets or liabilities, which is also recorded as a component of Interest income and other income (expense), net . |
| Foreign Currency Translation | Foreign Currency Translation Assets and liabilities of non-U.S. subsidiaries that operate in a local currency environment, where that local currency is the functional currency, are translated into U.S. dollars at exchange rates in effect at the balance sheet date, with the resulting translation adjustments directly recorded as a component of Accumulated other comprehensive loss |
| Revenue Recognition and Shipping and Handling Costs | Shipping and Handling Costs The Company records costs related to shipping and handling of revenue in cost of sales for all periods presented. Revenue Recognition In the first quarter of fiscal 2019, the Company adopted ASC 606 (“revenue standard”) using the retrospective transition method which requires the Company to recast each prior period presented. The most significant impact of the revenue standard relates to the Company’s accounting for contracts containing software solutions bundled with post-contract support (“PCS”) and/or services where, due to lack of vendor-specific objective evidence (“VSOE”) of fair value, the software revenue was deferred and recognized ratably over the support or service period. Revenue associated with the software under these types of contracts will now be recognized when control of the software is transferred, which is usually at the time of billing rather than ratably over the life of the support or service term. The actual revenue recognition treatment required under the standard will depend on contract-specific terms and in some instances transfer of control and revenue recognition may differ from the time of billing. Revenue recognition under the revenue standard for the remainder of the Company’s products and services remains substantially unchanged. The Company derives revenue from a diverse portfolio of network solutions and optical technology products and services, as follows: • Products: Network Enablement (“NE”) and Service Enablement (“SE”) products include instruments, microprobes and perpetual software licenses that support the development, production, maintenance and optimization of network systems. NE and SE are collectively referred to as Network and Service Enablement (“NSE”). The Company’s Optical Security and Performance (“OSP”) products include proprietary pigments used for optical security and optical filters used in commercial and government 3D Sensing applications. • Services: The Company also offers a range of product support and professional services designed to comprehensively address customer requirements. These include repair, calibration, extended warranty, software support, technical assistance, training and consulting services. Implementation services provided in conjunction with hardware or software solution projects include sale of the products along with project management, set-up and installation. Steps of revenue recognition The Company accounts for revenue in accordance with the revenue standard, in which the following five steps are applied to recognize revenue: 1. Identify the contract with a customer: Generally, the Company considers customer purchase orders which, in some cases are governed by master sales or other purchase agreements, to be the customer contract. All of the following criteria must be met before the Company considers an agreement to qualify as a contract with a customer under the revenue standard: (i) it must be approved by all parties; (ii) each party’s rights regarding the goods and services to be transferred can be identified; (iii) the payment terms for the goods and services can be identified; (iv) the customer has the ability and intent to pay and collection of substantially all of the consideration is probable; and, (v) the agreement has commercial substance. The Company utilizes judgment to determine the customer’s ability and intent to pay, which is based upon various factors including the customer’s historical payment experience or credit and financial information and credit risk management measures implemented by the Company. 2. Identify the performance obligations in the contract: The Company assesses whether each promised good or service is distinct for the purpose of identifying the various performance obligations in each contract. Promised goods and services are considered distinct provided that: (i) the customer can benefit from the good or service either on its own or together with other resources that are readily available to the customer; and, (ii) the Company's promise to transfer the good or service to the customer is separately identifiable or distinct from other promises in the contract. The Company's performance obligations consist of a variety of products and services offerings which include networking equipment; proprietary pigment, optical filters, proprietary software licenses; support and maintenance which includes hardware support that extends beyond the Company's standard warranties, software maintenance, installation, professional and implementation services, and training. Determining whether products and services are considered distinct performance obligations may require significant judgment. The Company may enter into contracts that involve a significant level of integration and interdependency between a software license and installation services. Judgment may be required to determine whether the software license is considered distinct in the context of the contract and accounted for separately, or not distinct in the context of the contract and accounted for together with the installation service. 3. Determine the transaction price: Transaction price reflects the amount of consideration to which the Company expects to be entitled in exchange for transferring goods or services to the customer. The Company’s contracts may include terms that could cause variability in the transaction price including rebates, sales returns, market incentives and volume discounts. Variable consideration is generally accounted for at the portfolio level and estimated based on historical information. If a contract includes a variable amount, the price adjustments are estimated at contract inception. In both cases, estimates are updated at the end of each reporting period as additional information becomes available. 4. Allocate the transaction price to performance obligations in the contract: If the contract contains a single performance obligation, the entire transaction price is allocated to that performance obligation. Many of the Company’s contracts include multiple performance obligations with a combination of distinct products and services, maintenance and support, professional services and/or training. Contracts may also include rights or options to acquire future products and/or services, which are accounted for as separate performance obligations by the Company, only if the right or option provides the customer with a material right that it would not receive without entering into the contract. For contracts with multiple performance obligations, the Company allocates the total transaction value to each distinct performance obligation based on relative standalone selling price (“SSP”). Judgment is required to determine the SSP for each distinct performance obligation. The best evidence of SSP is the observable price of a good or service when the Company sells that good or service separately under similar circumstances to similar customers. If a directly observable price is not available, the SSP must be estimated based on multiple factors including, but not limited to, historical pricing practices, internal costs, and profit objectives as well as overall market conditions. 5. Recognize revenue when (or as) performance obligations are satisfied: Revenue is recognized at the point in time control is transferred to the customer. For hardware sales, transfer of control to the customer typically occurs at the point the product is shipped or delivered to the customer’s designated location. For software license sales transfer of control to the customer typically occurs upon shipment, electronic delivery, or when the software is available for download by the customer. For sales of implementation service and solution contracts or in instances where software is sold along with essential installation services, transfer of control occurs and revenue is typically recognized upon customer acceptance. In certain instances, acceptance is deemed to have occurred if all acceptance provisions lapse, or if the Company has evidence that all acceptance provisions will be, or have been, satisfied. For fixed-price support and extended warranty contracts, or certain software arrangements which provide customers with a right to access over a discrete period, control is deemed to transfer over time and revenue is recognized on a straight-line basis over the contract term due to the stand-ready nature of the performance obligation. Revenue from hardware repairs and calibration services outside of an extended warranty or support contract is recognized at the time of completion of the related service. For other professional services or time-based labor contracts, revenue is recognized as the Company performs the services and the customers receive and/or consume the benefits. Revenue policy and practical expedients The following policy and practical expedient elections have been made by the Company under the revenue standard: • Revenue-based taxes as assessed by governmental authorities have been excluded from the measurement of transaction price(s). • Shipping and handling activities performed after the customer obtains control of the good are treated as activities to fulfill the promise (cost of fulfillment). Therefore, the Company does not evaluate whether the shipping and handling activities are promised services. • Incremental costs of obtaining contracts that would have been recognized within one year or less are recognized as an expense when incurred. These costs are included in selling, general, and administrative expenses (“SG&A”). The costs of obtaining contracts where the amortization period for recognition of the expense is beyond a year are capitalized and recognized over the revenue recognition period of the original contract. • The portfolio approach is used for certain types of variable consideration for contracts with similar characteristics. The methodology is used when the effects on the financial statements of applying this guidance to the portfolio would not differ materially from applying this guidance to the individual contracts within that portfolio. • If at contract inception, the expected period between the transfer of promised goods or services and payment is within one year or less, the Company forgoes adjustment for the impact of significant financing component for the contract. • For contracts that were modified before the beginning of the earliest reporting period presented, the Company has applied a transition practical expedient and will not recast the contracts for those modifications. Instead, the Company has reflected the aggregate effect of all modifications when identifying the satisfied and unsatisfied performance obligations, determining the transaction price and allocating the transaction price. • For the reporting periods presented before the date of initial application, the amount of the transaction price allocated to the remaining performance obligations and the explanation of when it expects to recognize that amount as revenue is not disclosed. Remaining performance obligations: Remaining performance obligations represent the aggregate amount of the transaction price allocated to performance obligations not delivered or are incomplete, as of June 29, 2019 . Remaining performance obligations include deferred revenue plus unbilled amounts not yet recorded. The aggregate amount of the transaction price allocated to remaining performance obligations does not include amounts owed under cancelable contracts where there is no substantive termination penalty. The Company also applied the practical expedient to not disclose the amount of transaction price allocated to remaining performance obligations for the periods prior to adoption of the new revenue standard. Remaining performance obligation estimates are subject to change and are affected by several factors, including terminations, changes in the scope of contracts, periodic revalidation, adjustments for revenue that has not materialized, and adjustments for currency. Receivables: The Company records a receivable when an unconditional right to consideration exists and transfer of control has occurred, such that only the passage of time is required before payment of consideration is due. Timing of revenue recognition may differ from the timing of customer invoicing. Payment terms vary based on product or service offerings and payment is generally required within 30 to 90 days from date of invoicing. Certain performance obligations may require payment before delivery of the service to the customer . Contract assets: A contract asset is recognized when a conditional right to consideration exists and transfer of control has occurred. Contract assets include fixed fee professional services, where the transfer of services has occurred in advance of the Company's right to invoice. Contract assets are included in prepayments and other current assets on the consolidated balance sheet. There were contract assets of $3.9 million and $1.3 million as of June 29, 2019 and June 30, 2018 , respectively. Contract asset balances will fluctuate based upon the timing of transfer of services, billings and customers’ acceptance of contractual milestones. Deferred revenue: Deferred revenue consists of contract liabilities primarily related to support, solution deployment services, software maintenance, product, professional services, and training when the Company has a right to invoice or payments have been received and transfer of control has not occurred. Revenue is recognized on these items when the revenue recognition criteria are met, generally resulting in ratable recognition over the contract term. Contract liabilities are included in other current liabilities on the consolidated balance sheets. The Company also has short term and long term deferred revenues related to undelivered hardware and professional services, consisting of installations and consulting engagements, which are recognized as the Company's performance obligations under the contract are completed and accepted by the customer. |
| Warranty | Warranty The Company provides reserves for the estimated costs of product warranties at the time revenue is recognized. It 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. |
| Advertising Expense | Advertising Expense |
| Research and Development Expense | Research and Development Expense Costs related to research and development (“R&D”), which primarily consists of labor and benefits, supplies, facilities, consulting and outside service fees, are charged to expense as incurred. The authoritative guidance allows for capitalization of software development costs incurred after a product’s technological feasibility has been established until the product is available for general release to the public. The Company believe its software development process is completed concurrent with the establishment of technological feasibility. As such, software development costs have been expensed as incurred. |
| Stock-Based Compensation | Stock-Based Compensation Stock-based compensation expense is measured at the grant date based on the fair value of the award. The Company recognizes stock-based compensation cost over the award’s requisite service period on a straight-line basis. No compensation cost is recognized for awards forfeited by employees who do not render requisite service. The fair value of restricted stock units (“RSUs”) and performance-based restricted stock units (“PSUs”) that do not contain a market condition, is equal to the market value of the Company’s common stock on the grant date. The fair value of PSUs that contain a market condition is estimated using the Monte Carlo simulation option-pricing model. PSUs have vesting requirements tied to either the performance of the Company’s stock as compared to the NASDAQ telecommunications index or the performance of the Company’s operating results, and could vest at a higher or lower rate, or not at all, based on relative performance described. The Company estimates the fair value of stock options and Employee Stock Purchase Plan (“ESPP”) purchase rights using the Black-Scholes Merton (“BSM”) option-pricing model. This option-pricing model requires the input of assumptions, including the award’s expected life and the price volatility of the underlying stock. The Company does not apply expected forfeiture rate and accounts for forfeitures as they occur. The total fair value of the equity awards is recorded on a straight-line basis, over the requisite service period of the awards for each separate vesting period of the award, except for PSUs with market-based assumptions, which are amortized based upon graded vesting method. |
| Income Taxes | Income Taxes In accordance with the authoritative guidance on accounting for income taxes, the Company recognizes income taxes using an asset and liability approach. This approach requires the recognition of taxes payable or refundable for the current year and deferred tax liabilities and assets for future tax consequences of events that have been recognized in the Company’s consolidated financial statements or tax returns. The measurement of current and deferred taxes is based on provisions of the enacted tax law and the effects of future changes in tax laws or rates are not anticipated. The authoritative guidance provides for recognition of deferred tax assets if the realization of such deferred tax assets is more likely than not to occur based on an evaluation of both positive and negative evidence and the relative weight of the evidence. With the exception of certain international jurisdictions, the Company has determined that at this time it is more likely than not that deferred tax assets attributable to the remaining jurisdictions will not be realized, primarily due to uncertainties related to its ability to utilize its net operating loss carryforwards before they expire. Accordingly, the Company has established a valuation allowance for such deferred tax assets. If there is a change in the Company’s ability to realize its deferred tax assets for which a valuation allowance has been established, then its tax provision may decrease in the period in which it determines that realization is more likely than not. Likewise, if the Company determines that it is not more likely than not that its deferred tax assets will be realized, then a valuation allowance may be established for such deferred tax assets and the Company’s tax provision may increase in the period in which the Company make the determination. The authoritative guidance on accounting for uncertainty in income taxes prescribes the recognition threshold and measurement attributes for financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. Additionally, it provides guidance on recognition, classification, and disclosure of tax positions. The Company is subject to income tax audits by the respective tax authorities in the jurisdictions in which it operates. The determination of tax liabilities in each of these jurisdictions requires the interpretation and application of complex and sometimes uncertain tax laws and regulations. The Company recognizes liabilities based on its estimate of whether, and the extent to which, additional tax liabilities are more likely than not. If the Company ultimately determines that the payment of such a liability is not necessary, then it reverses the liability and recognizes a tax benefit during the period it is determined no longer necessary. The recognition and measurement of current taxes payable or refundable and deferred tax assets and liabilities requires that the Company make certain estimates and judgments. Changes to these estimates or a change in judgment may have a material impact on the Company’s tax provision in a future period. |
| Restructuring Accrual | Restructuring Accrual In accordance with authoritative guidance on accounting for costs associated with exit or disposal activities, generally costs associated with restructuring activities are recognized when they are incurred. However, in the case of operating and direct financing leases, the expense is estimated and accrued when the property is vacated. Given the significance of, and the timing of the execution of such activities, this process is complex and involves periodic reassessments of estimates made from the time the property was vacated, including evaluating real estate market conditions for expected vacancy periods and sub-lease income. Additionally, a liability for post-employment benefits for workforce reductions related to restructuring activities is recorded when payment is probable, and the amount is reasonably estimable. The Company continually evaluates the adequacy of the remaining liabilities under its restructuring initiatives. Although the Company believes that these estimates accurately reflect the costs of its restructuring plans, actual results may differ, thereby requiring the Company to record additional liabilities or reverse a portion of existing liabilities. |
| Contingencies | Contingencies The Company is subject to various potential loss contingencies arising in the ordinary course of business. In determining a loss contingency, the Company considers the likelihood of loss or impairment of an asset or the incurrence of a liability, as well as its ability to reasonably estimate the amount of loss. An estimated loss is accrued when it is probable that an asset has been impaired, a liability has been incurred and the amount of loss can be reasonably estimated. The Company regularly evaluates current information available to determine whether such accruals should be adjusted and whether new accruals are required. Contingent liabilities include contingent consideration in connection with the Company’s acquisitions, which represent earn-out payments and is recognized at fair value on the acquisition date and remeasured each reporting period with subsequent adjustments recognized in the Selling, general and administrative expense of the Company’s Consolidated Statements of Operations.

| Recent Accounting Pronouncements | Recent Accounting Pronouncements Adopted In November 2016, the Financial Accounting Standards Board (“FASB”) issued an accounting standard update (“ASU”) that requires a statement of cash flows to present the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. In the first quarter of fiscal 2019, the Company adopted this ASU using a retrospective transition method. Accordingly, the Company’s consolidated statements of cash flows for the fiscal years ended June 29, 2019 , June 30, 2018 and July 1, 2017 as presented herein, have been restated to comply with the new requirements. In May 2014, the FASB issued new authoritative guidance related to revenue recognition from contracts with customers, ASC 606 - Revenue from Contracts with Customers (the “revenue standard”). The new guidance provides a unified model to determine when and how revenue is recognized. The core principle of the new guidance is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration for which the entity expects to be entitled in exchange for those goods or services. The Company adopted the new standard effective in the first quarter of fiscal 2019 using the retrospective transition method, which required the Company to recast each prior period presented consistent with the new guidance. Refer to “ Note 1. Basis of Presentation ” of the Consolidated Financial Statements for a summary of significant policies related to the new accounting standards. As part of the adoption, certain prior period amounts have been adjusted or reclassified within the consolidated financial statements. The following table presents the impact of the revenue standard adoption, to select line items of the Company’s Consolidated Balance Sheet as of June 30, 2018 , ( in millions ): June 30, 2018 As Reported Adjustment As Adjusted ASSETS Accounts receivable, net $ 217.5 $ 1.1 $ 218.6 Prepayments and other assets 54.8 1.5 56.3 Deferred income taxes 114.5 (0.2 ) 114.3 Other non-current assets 13.6 1.8 15.4 Total assets $ 2,022.6 $ 4.2 $ 2,026.8 LIABILITIES AND STOCKHOLDERS’ EQUITY Deferred revenue $ 71.9 $ (11.3 ) $ 60.6 Accrued payroll and related expenses 51.4 1.4 52.8 Other current liabilities 77.0 1.9 78.9 Other non-current liabilities 182.8 (2.0 ) 180.8 Total stockholders’ equity (1) 720.7 14.2 734.9 Total liabilities and stockholders’ equity $ 2,022.6 $ 4.2 $ 2,026.8 (1) Reflects the cumulative impact of $23.8 million on total stockholders’ equity from the revenue standard adoption as of the beginning of fiscal 2017 The primary impacts to the previously issued amounts are as follows: Accounts receivable, net: Adoption of the new revenue standard resulted in an increase to accounts receivable, net, primarily due to the following two items: 1) The return rights provision, which represents a liability for expected customer returns, was previously presented as a reduction to accounts receivable and is now presented in other current liabilities; and, 2) Contract assets which are recorded when a conditional right to consideration exists and transfer of control has occurred in advance of the Company’s right to invoice. Upon adoption of ASC 606, contract assets, which were previously presented as a component of accounts receivable, net, are now presented as a component of prepayments and other current assets. Prepayments and other current assets: As noted above, contract assets, which are recognized when a conditional right to consideration exists and transfer of control has occurred in advance of the Company’s right to invoice. Upon adoption of ASC 606, contract assets are presented as a component of prepayments and other current assets. Other non-current assets: The costs of obtaining contracts where the amortization period for recognition of the expense is beyond a year, are capitalized and recognized over the revenue recognition period of the original contract. These costs are now classified as other non-current assets. Short-term and long-term deferred revenue: Adoption of the new revenue standard resulted in a decrease of deferred revenue primarily due to the net change in timing of software related revenue. Under the previous standard revenue for software license sales bundled with post-contract support and/or services where vendor-specific objective evidence of fair value had not been established was recognized ratably over the support period. Upon adoption of ASC 606 the revenue related to such software license sales will now be recognized when control transfers, which is usually at the time of billing. The actual revenue recognition treatment required under the standard will depend on contract-specific terms and in some instances, transfer of control and revenue recognition may differ from the time of billing. Long-term deferred revenue is presented under other non-current liabilities. Other current liabilities: The returns provision, which represents a liability for expected customer returns, was previously presented as a reduction of accounts receivable and is now presented as other current liabilities. Adoption of the revenue standard had no impact on net cash provided by or used in operating, investing or financing activities as presented on the Company’s Consolidated Statements of Cash Flows. The following table presents the impact of the revenue standard adoption to select line items of the Company’s previously reported Consolidated Statements of Operations for the twelve months ended June 30, 2018 and July 1, 2017 ( in millions, except per share data ): Twelve Months Ended June 30, 2018 Twelve Months Ended July 1, 2017 As Reported Adjustment As Adjusted As Reported Adjustment As Adjusted Revenues: Product revenue $ 783.1 $ (10.6 ) $ 772.5 $ 726.4 $ (20.4 ) $ 706.0 Service revenue 97.3 5.9 103.2 85.0 14.0 99.0 Total net revenue 880.4 (4.7 ) 875.7 811.4 (6.4 ) 805.0 Cost of revenues: Product cost of revenue 314.7 (4.1 ) 310.6 260.9 (1.3 ) 259.6 Service cost of revenue 46.8 3.2 50.0 50.2 1.9 52.1 Amortization of acquired technologies 26.7 — 26.7 14.3 — 14.3 Total cost of revenue 388.2 (0.9 ) 387.3 325.4 0.6 326.0 Gross profit 492.2 (3.8 ) 488.4 486.0 (7.0 ) 479.0 Income from operations 5.1 (3.2 ) 1.9 13.6 (6.6 ) 7.0 (Loss) income before taxes (32.6 ) (3.1 ) (35.7 ) 186.6 (6.6 ) 180.0 Provision for income taxes 13.4 (0.5 ) 12.9 21.3 0.1 21.4 Net (loss) income $ (46.0 ) $ (2.6 ) $ (48.6 ) $ 166.9 $ (6.7 ) $ 160.2 Net loss per common share: Basic $ (0.20 ) $ (0.01 ) $ (0.21 ) $ 0.73 $ (0.03 ) $ 0.70 Diluted $ (0.20 ) $ (0.01 ) $ (0.21 ) $ 0.71 $ (0.03 ) $ 0.68 Shares used in per share calculations: Basic 227.1 227.1 229.9 229.9 Diluted 227.1 227.1 234.5 234.5 The impacts to the previously reported amounts are summarized, as follows: Net revenue: Adoption of the revenue standard resulted in a change in the timing of revenue recognized primarily due to the treatment of software license revenue. Under the prior standard, if vendor-specific objective evidence had not been established for the post contract support and/or the services, software license revenue would have been recognized ratably over the support period. Upon adoption of ASC 606, revenue related to such software license sales will now be recognized when control transfers which is usually at the time of billing. The decrease in revenue for the period presented above is primarily the result of the elimination of ratable software license revenue. Such license revenue was previously amortized; however it is now recognized at a point in time under the new standard. In October 2016, the FASB issued guidance that requires entities to recognize at the transaction date the income tax consequences of intra-entity transfer of an asset other than inventory. In the first quarter of fiscal 2019, the Company adopted this ASU, which did not have a material impact to our Consolidated Financial Statements. Recent Accounting Pronouncements Not Yet Adopted In August 2018, the FASB issued guidance to amend the disclosure requirements related to defined benefit pension and other post-retirement plans. Some of the changes include adding a disclosure requirement for significant gains and losses related to changes in the benefit obligation for the period, and removing the amounts in accumulated other comprehensive income expected to be recognized as components of net periodic benefit cost over the next fiscal year. This guidance is effective for the Company in the first quarter of fiscal 2022 and early adoption is permitted. The Company is evaluating the impact of adopting this new accounting guidance on its Consolidated Financial Statements. In August 2018, the FASB issued guidance which changes the fair value measurement disclosure requirements of FASB ASC - Fair Value Measurement (Topic 820) . The update includes new, eliminated and modified disclosure requirements. The guidance is effective for the Company in the first quarter of fiscal 2020 and early adoption is permitted for any eliminated or modified disclosures. The Company does not expect the adoption of this standard will have a material impact on its consolidated financial statements. In June 2016, the FASB issued guidance that changes the accounting for recognizing impairments of financial assets. Under the new guidance, credit losses for certain types of financial instruments will be estimated based on expected losses. The new guidance also modifies the impairment models for available-for-sale debt securities and for purchased financial assets with credit deterioration since their origination. The guidance is effective for the Company in the first quarter of fiscal 2021 and earlier adoption is permitted. The Company does not expect the adoption of this standard will have a material impact on its consolidated financial statements. In February 2016, the FASB issued guidance regarding both operating and financing leases, including requiring lessees to recognize lease with a term greater than one year on their balance sheets as a right-of-use (“ROU”) assets and corresponding lease liabilities, measured on a discounted basis over the lease term. The guidance requires a modified retrospective transition approach for leases existing at, or entered after, the beginning of the earliest comparative period presented in the financial statements. In July 2018, the FASB issued an update, which provides entities another option for transition, allowing entities to not apply the new standard in the comparative periods they present in their financial statements in the year of adoption. The guidance is effective for the Company in the first quarter of fiscal 2020 and the Company will elect the optional transition approach of not adjusting its comparative period financial statements for the impacts of adoption. The Company has chosen the package of practical expedients to not reassess whether a contract contains a lease, lease classification and accounting for initial direct costs. While the Company is currently finalizing its implementation of new policies, processes and internal controls to comply with the new rules, the Company expects the adoption of the standard will result in the recognition of ROU assets and lease liabilities for operating leases between $35 million and $40 million at the beginning of the first quarter of fiscal 2020, with the most significant impact from recognition of ROU assets and lease liabilities related to the Company’s real estate leases. In addition, the Company expects to record an adjustment to accumulated deficit, net of taxes, of approximately $3 million from the recognition of previously deferred profit under sale-leaseback arrangements and de-recognition of related real estate assets of approximately $7 million and financing obligation of approximately $10 million . The adoption of the new standard will not have a material impact on Consolidated Statements of Operations and Consolidated Statement of Cash Flows. |
