Basis of Presentation and Summary of Significant Accounting Policies |
Principles of Consolidation | Principles of Consolidation The consolidated financial statements include the accounts of the Company, and its wholly owned subsidiaries. All material intercompany accounts and transactions have been eliminated in consolidation.
Fiscal Year | Fiscal Year The Company's fiscal year is a 52 or 53-week period ending on the last Sunday in the month of June. The Company's 2011 fiscal year extended from June 28, 2010 to June 26, 2011 and was a 52-week fiscal year. The Company's 2010 fiscal year extended from June 29, 2009 to June 27, 2010 and was a 52-week fiscal year. The Company's 2009 fiscal year extended from June 30, 2008 to June 28, 2009 and was a 52-week fiscal year. The Company's 2012 fiscal year will extend from June 27, 2011 to June 24, 2012 and will be a 52-week fiscal year.
Reclassifications | Reclassifications Certain prior period amounts in the accompanying consolidated financial statements have been reclassified to conform to the current year presentation. These reclassifications had no effect on previously reported net income or shareholders' equity.
Use of Estimates | The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America ("U.S. GAAP") requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, and the disclosure of contingent assets and liabilities. On an ongoing basis, the Company evaluates its estimates, including those related to revenue recognition, provision for doubtful accounts, sales returns, sales price discounts and incentives, provision for inventory obsolescence, fair value of investments, fair value of acquired intangible assets and goodwill, useful lives of intangible assets and property and equipment, income taxes, product warranty obligations, employee stock options, and contingencies and litigation, among others. The Company generally bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual amounts could differ from those estimates.
Segment Information | Segment Information The Company follows U.S. GAAP with respect to disclosures regarding reportable segments. U.S. GAAP requires segmentation based on an entity's internal organization and reporting of revenue and operating income based upon internal accounting methods commonly referred to as the "management approach." Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker, or decision making group, in deciding how to allocate resources and in assessing performance. The Company's chief operating decision maker is its Chief Executive Officer. The Company has determined that it currently operates as one reportable segment.
Cash and Cash Equivalents | Cash and Cash Equivalents Cash and cash equivalents consist of unrestricted cash accounts and highly liquid investments with an original maturity of three months or less when purchased. Cash and cash equivalents are carried at cost, which approximates fair value. The Company holds cash and cash equivalents at several major financial institutions, which often exceed insurance limits set by the Federal Deposit Insurance Corporation ("FDIC"). The Company has not historically experienced any losses due to such concentration of credit risk.
Investments | Investments Investments in certain securities may be classified into three categories:
| • |  | Held-to-Maturity – Debt securities that the entity has the positive intent and ability to hold to maturity are reported at amortized cost.
| • |  | Trading Securities – Debt and equity securities that are bought and held principally for the purpose of selling in the near term are reported at fair value, with unrealized gains and losses included in earnings.
| • |  | Available-for-Sale – Debt and equity securities not classified as either securities held-to-maturity or trading securities are reported at fair value with unrealized gains or losses excluded from earnings and reported as a separate component of shareholders' equity.
The Company reassesses the appropriateness of the classification (i.e. held-to-maturity, trading securities, or available-for-sale) of its investments at the end of each reporting period. When the fair value of an investment declines below its original cost, the Company considers all available evidence to evaluate whether the decline is other-than-temporary. Among other things, the Company considers the duration and extent of the decline and economic factors influencing the markets. To date, the Company has had no such other-than-temporary declines below cost basis. The Company utilizes specific identification in computing realized gains and losses on the sale of investments. Realized gains and losses on investments are reported in other income and expense. Investments in marketable securities with maturities beyond one year may be classified as short term based on their highly liquid nature and because such marketable securities represent the investment of cash that is available for current operations.
Inventories | Inventories Inventories are valued at the lower of cost or market value, with cost being determined on the first-in, first-out ("FIFO") method or the average cost method. The Company writes down its inventory balances for estimates of excess and obsolete amounts. These write-downs are recorded as a component of cost of sales. At the point of the write-down, a new, lower-cost basis for that inventory is established, and any subsequent improvements in facts and circumstances do not result in the restoration or increase in that newly established cost basis. The Company recorded charges for write-downs in inventory of $14.6 million, $16.2 million and $11.7 million, for fiscal 2011, 2010 and 2009, respectively.
Property and Equipment | Property and Equipment Property and equipment are recorded at cost and depreciated on a straight-line basis over the assets' estimated useful lives. Leasehold improvements are amortized over the lesser of the asset life or the life of the related lease. In general, the useful lives are as follows:
Manufacturing equipment |  | 3 to 5 years
Buildings and building improvements |  | 5 to 40 years
Furniture and office equipment |  | 3 to 5 years
Leasehold improvements |  | Shorter of estimated useful life or lease term
Expenditures for repairs and maintenance are charged to expense as incurred. The costs for major renewals and improvements are capitalized and depreciated over their estimated useful lives. The cost and related accumulated depreciation of the assets are removed from the accounts upon disposition and any resulting gain or loss is reflected in operations.
Shipping and Handling Costs | Shipping and Handling Costs Shipping and handling costs are included in cost of revenues and are recognized as a period expense during the period in which they are incurred.
Intangible Assets and Goodwill | Intangible Assets and Goodwill The Company records the assets acquired and liabilities assumed in business combinations at their respective fair values at the date of acquisition, with any excess purchase price recorded as goodwill. Valuation of intangible assets and in-process research and development entails significant estimates and assumptions including, but not limited to, determining the timing and expected costs to complete development projects, estimating future cash flows from product sales, developing appropriate discount rates, estimating probability rates for the successful completion of development projects, continuation of customer relationships and renewal of customer contracts, and approximating the useful lives of the intangible assets acquired. Patent rights reflect costs incurred by the Company in applying for and maintaining patents owned by the Company and in purchasing patents and related rights from third parties. License rights reflect costs incurred by the Company in acquiring licenses under patents owned by others. The Company amortizes both on a straight-line basis over the expected useful life of the associated patent rights, which is generally the lesser of 20 years from the date of the patent application or the license period. Royalties payable under licenses for patents owned by others are expensed as incurred. U.S. GAAP requires that intangible assets other than goodwill with an indefinite life should not be amortized until their life is determined to be finite, and all other intangible assets must be amortized over their useful lives. The Company is currently amortizing its acquired intangible assets with definite lives over periods ranging from one to fourteen years. The Company tests goodwill for impairment at the reporting unit level at least annually and potentially more frequently upon the occurrence of certain events. Goodwill is tested for impairment annually on the first business day of each fiscal April using a two-step process. First, the Company determines if the carrying amount of any of its reporting units exceeds its fair value (determined using discounted cash flows or market multiples based on revenues), which would indicate a potential impairment of goodwill associated with that reporting unit. If the Company determines that a potential impairment of goodwill exists, it then compares the implied fair value of the goodwill associated with the respective reporting unit, to its carrying amount to determine if there is an impairment loss.
Impairment of Long-Lived Assets | Impairment of Long-Lived Assets The Company reviews long-lived assets such as property, equipment, definite lived intangible assets and patents for impairment based on changes in circumstances that indicate their carrying amounts may not be recoverable. In making these determinations, the Company uses certain assumptions, including but not limited to: (1) estimations of the fair market value of the assets, and (2) estimations of future cash flows expected to be generated by these assets, which are based on additional assumptions such as asset utilization, length of service the asset will be used in the Company's operations and estimated salvage values. The Company also reviews its capitalized patent portfolio and records impairment charges when circumstances warrant, such as when patents have been abandoned or are no longer being pursued.
Contingent Liabilities | Contingent Liabilities The Company provides for contingent liabilities when (1) it is probable that an asset has been impaired or a liability has been incurred at the date of the financial statements and (2) the amount of the loss can be reasonably estimated. Disclosure in the notes to the financial statements is required for loss contingencies that do not meet both these conditions if there is a reasonable possibility that a loss may have been incurred. See Note 13, "Commitments and Contingencies," for a discussion of loss contingencies in connection with pending and threatened litigation. The Company expenses as incurred the costs of defending legal claims against the Company.
Revenue Recognition | Revenue Recognition The Company recognizes product revenue when the earnings process is complete, as evidenced by persuasive evidence of an arrangement, typically in the form of a purchase order, when the sales price is fixed or determinable, collection of revenue is reasonably assured, and title and risk of loss have passed to the customer. The Company provides its customers with limited rights of return for non-conforming shipments and product warranty claims. The Company estimates an allowance for anticipated sales returns based upon an analysis of historical sales returns and other relevant data. The Company records an allowance at the time of sale, which is recorded as a reduction of product revenue in the Consolidated Statements of Income and as a reduction to accounts receivable in the Consolidated Balance Sheets. A substantial portion of the Company's products are sold through distributors. Distributors stock inventory and sell the Company's products to their own customer base, which may include: value added resellers; manufacturers who incorporate the Company's products into their own manufactured goods; or ultimate end users of the Company's products. The Company recognizes revenue under the same terms as described. Certain of the Company's distributors are provided limited rights that allow them to return a portion of inventory (Product Exchange Rights or Stock Rotation Rights) and receive credits for changes in selling prices (Price Protection Rights) and targeted customer pricing arrangements under our "ship and debit" program. These estimates are calculated based upon historical experience, product shipment analysis, current economic conditions, on-hand inventory at the distributor, and customer contractual arrangements. The Company believes that it can reasonably and reliably estimate the allowance for distributor credits at the time of sale. Accordingly, estimates for these rights are recorded at the time of sale as a reduction of product revenue in the Consolidated Statements of Income and as a reduction to accounts receivable in the Consolidated Balance Sheets. On occasion, the Company will issue a new price book for its product, at which time the Company will provide a credit to certain distributors for inventory quantities on hand if required by the Company's agreement with the distributor. This practice is known as price protection. These credits are applied against the reserve that the Company establishes upon initial shipment of product to the distributor. Under the ship and debit program, products are sold to distributors at published prices which are contained in price books provided to various distributors. Distributors are required to pay for product within the Company's standard commercial terms. Subsequent to the initial product purchase, a distributor may request a price allowance for a particular part number(s) for certain target customers, prior to the distributor reselling the particular part. Once the Company has approved an allowance, the distributor resells the product to the target customer, and the Company credits the distributor according to the allowance approved. These credits are applied against a reserve the Company establishes upon initial shipment of product to the distributor. In addition, the Company periodically runs sales incentive programs with certain of its distributors and resellers, such as product rebates and cooperative advertising campaigns. The Company recognizes these incentives at the time they are offered for consideration given to customers, and records a credit to the customer's account and offsetting expense as either a reduction to revenue, increase to cost of sales, or marketing expense depending on the type of sales incentive. From time to time, the Company may enter into licensing arrangements related to its intellectual property. Revenue from licensing arrangements is recognized when earned and estimable. The timing of revenue recognition is dependent on the terms of each license agreement. Generally, the Company will recognize non-refundable upfront license fees related to patent licenses immediately upon receipt of the funds if the Company has no significant future obligations to perform under the arrangement. However, the Company will defer recognition for licensing fees where the Company has significant future performance requirements, the fee is not fixed (such as royalties earned as a percentage of future sales), or the fees are otherwise contingent.
Accounts Receivable | Accounts Receivable For product sales, the Company typically invoices its customers at shipment for the sales order value of products shipped. For contract revenue, invoicing occurs based upon the terms of the specific research contract, typically one month in arrears for services rendered and any other allowable direct costs. Accounts receivable are recorded at the invoiced amount and do not bear interest. The Company does not have any off-balance sheet credit exposure related to any of its customers.
Allowance for Doubtful Accounts | Allowance for Doubtful Accounts The Company evaluates the collectability of accounts receivable based on a combination of factors. In cases where the Company becomes aware of circumstances that may impair a specific customer's ability to meet its financial obligations subsequent to the original sale, the Company will record an allowance against amounts due, and thereby reduce the net recognized receivable to the amount the Company reasonably believes will be collected. For all other customers, the Company recognizes an allowance for doubtful accounts based on the length of time the receivables are past due and consideration of other factors such as industry conditions, the current business environment and its historical experience.
Advertising | Advertising The Company expenses the costs of producing advertisements at the time production occurs and expenses the cost of communicating the advertising in the period in which the advertising is used. Advertising costs are included in selling, general and administrative expenses and amounted to approximately $5.7 million, $4.2 million and $3.1 million for the years ended June 26, 2011, June 27, 2010 and June 28, 2009, respectively.
Research and Development | Research and Development Research and development activities are expensed as incurred. For contracts under which the Company anticipates that direct costs will exceed amounts to be funded over the life of the contract, costs are reported as research and development expenses and related funding as an offset of those expenses.
Earnings Per Share | Earnings Per Share Basic earnings per share is computed by dividing net income by the weighted average number of shares of common stock outstanding for the applicable period. Diluted earnings per share is determined in the same manner as basic earnings per share except that the number of shares is increased to assume exercise of potentially dilutive stock options, unvested restricted stock and contingently issuable shares using the treasury stock method, unless the effect of such increases would be anti-dilutive. Under the treasury stock method, the amount the employee must pay for exercising stock options, the amount of compensation cost for future service that the Company has not yet recognized, and the amount of tax benefits that would be recorded in additional paid-in capital when the award becomes deductible are assumed to be used to repurchase shares.
Accounting for Stock-Based Compensation | Accounting for Stock-Based Compensation The Company recognizes compensation expense in its consolidated financial statements for all share-based payments granted based on the fair value on the date of grant. Compensation expense is then recognized over the award's vesting period.
Fair Value of Financial Instruments | Fair Value of Financial Instruments The carrying amounts of cash and cash equivalents, available-for-sale securities, accounts and interest receivable, accounts payable and other liabilities approximate fair values at June 26, 2011 and June 27, 2010 due to the short-term nature of these instruments.
Taxes | Taxes The Company uses the asset and liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the consolidated financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets are recognized for deductible temporary differences, along with net operating loss carryforwards and credit carryforwards, if it is more likely than not that the tax benefits will be realized. To the extent a deferred tax asset cannot be recognized under the preceding criteria, allowances are established. Deferred tax assets and liabilities are measured using enacted tax rates in effect for the year in which those temporary differences are expected to be recovered or settled. Taxes payable which are not based on income are accrued ratably over the period to which they apply. For example, payroll taxes are accrued each period end based upon the amount of payroll taxes that are owed as of that date; whereas taxes such as property taxes and franchise taxes are accrued over the fiscal year to which they apply if paid at the end of a period, or they are amortized ratably over the fiscal year if they are paid in advance.
Foreign Currency Translation | Foreign Currency Translation Prior to the fourth quarter of fiscal 2009, certain of the Company's international subsidiaries had a non-U.S. Dollar functional currency. However, during the fourth quarter of fiscal 2009, due to a further refinement of the Company's global supply chain, the Company determined that its international subsidiaries had the U.S. Dollar as their functional currency. However, because the Company and its subsidiaries still transact business in currencies other than the U.S. Dollar, the Company will continue to experience a certain amount of foreign currency exchange gains and losses. In addition, historical foreign currency translation gains and losses will continue to exist in the Company's balance of Accumulated Other Comprehensive Income until such subsidiaries are sold or substantially liquidated.
Recently Adopted Accounting Pronouncements | Recently Adopted Accounting Pronouncements Transfers of Financial Assets In June 2009, the Financial Accounting Standards Board (the "FASB") issued new guidance concerning the transfer of financial assets. This guidance amends the criteria for a transfer of a financial asset to be accounted for as a sale, creates more stringent conditions for reporting a transfer of a portion of a financial asset as a sale, changes the initial measurement of a transferor's interest in transferred financial assets, eliminates the qualifying special-purpose entity concept and provides for new disclosures. This guidance became effective for the Company beginning in the first quarter of fiscal 2011. The Company's adoption of the new accounting guidance did not have a significant impact on its consolidated financial statements. Determining the Primary Beneficiary of a Variable Interest Entity In June 2009, the FASB issued new guidance concerning the determination of the primary beneficiary of a variable interest entity ("VIE"). This new guidance amends current U.S. GAAP by: requiring ongoing reassessments of whether an enterprise is the primary beneficiary of a VIE; amending the quantitative approach previously required for determining the primary beneficiary of the VIE; modifying the guidance used to determine whether an entity is a VIE; adding an additional reconsideration event (e.g., troubled debt restructurings) for determining whether an entity is a VIE; and requiring enhanced disclosures regarding an entity's involvement with a VIE. This guidance became effective for the Company beginning in the first quarter of fiscal 2011. The Company's adoption of the new accounting guidance did not have a significant impact on its consolidated financial statements. Revenue Recognition with Multiple Deliverables In October 2009, the FASB issued new standards for revenue recognition with multiple deliverables. These new standards impact the determination of when the individual deliverables included in a multiple-element arrangement may be treated as separate units of accounting. Additionally, these new standards modify the manner in which the transaction consideration is allocated across the separately identified deliverables by no longer permitting the residual method of allocating arrangement consideration. This guidance became effective for the Company beginning in the first quarter of fiscal 2011. The Company's adoption of the new accounting guidance did not have a significant impact on its consolidated financial statements.
Recently Issued Accounting Pronouncements | Recently Issued Accounting Pronouncements Presentation of Comprehensive Income In June 2010, the FASB issued new guidance concerning the presentation of total comprehensive income and its components. Under this guidance an entity has the option to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in single continuous statement of comprehensive income or in two separate but consecutive statements. This guidance will become effective for the Company beginning in the third quarter of fiscal 2012. The Company's adoption of the new accounting guidance is not expected to have a significant impact on its consolidated financial statements. Fair Value Disclosures In January 2010, the FASB issued amended standards requiring additional fair value disclosures. The amended standards require disclosures of transfers in and out of Levels 1 and 2 of the fair value hierarchy, as well as requiring gross basis disclosures for purchases, sales, issuances and settlements within the Level 3 reconciliation. Additionally, the update clarifies the requirement to determine the level of disaggregation for fair value measurement disclosures and to disclose valuation techniques and inputs used for both recurring and nonrecurring fair value measurements in either Level 2 or Level 3. The Company adopted the new guidance in the third quarter of fiscal 2010, except for the disclosures related to purchases, sales, issuance and settlements, which will be effective for the Company beginning in the first quarter of fiscal 2012. Because these new standards are related primarily to disclosures, their adoption has not had, and is not expected to have, a significant impact on the Company's consolidated financial statements.
