2. Summary of Significant Accounting Policies

Cash and Cash Equivalents

Cash and cash equivalents consist primarily of money market funds, commercial paper, and U.S. Government Treasury and Agency instruments with original maturities of three months or less at the date of purchase.

Marketable Securities

We determine the appropriate classification of marketable securities at the time of purchase and reevaluate this designation as of each balance sheet date. We classify these securities as either held-to-maturity, trading, or available-for-sale. As of March 28, 2015 and March 29, 2014, all marketable securities were classified as available-for-sale securities. The Company classifies its investments as “available for sale” because it expects to possibly sell some securities prior to maturity. The Company’s investments are subject to market risk, primarily interest rate and credit risk. The Company’s investments are managed by an outside professional manager within investment guidelines set by the Company. Such guidelines include security type, credit quality, and maturity, and are intended to limit market risk by restricting the Company’s investments to high quality debt instruments with relatively short-term maturities. The fair value of investments is determined using observable or quoted market prices for those securities.

Available-for-sale securities are carried at fair value, with unrealized gains and losses included as a component of accumulated other comprehensive loss. Realized gains and losses, declines in value judged to be other than temporary, and interest on available-for-sale securities are included in net income. The cost of securities sold is based on the specific identification method.

Inventories

We use the lower of cost or market method to value our inventories, with cost being determined on a first-in, first-out basis. One of the factors we consistently evaluate in the application of this method is the extent to which products are accepted into the marketplace. By policy, we evaluate market acceptance based on known business factors and conditions by comparing forecasted customer unit demand for our products over a specific future period, or demand horizon, to quantities on hand at the end of each accounting period.

On a quarterly and annual basis, we analyze inventories on a part-by-part basis. Product life cycles and the competitive nature of the industry are factors considered in the evaluation of customer unit demand at the end of each quarterly accounting period. Inventory quantities on-hand in excess of forecasted demand is considered to have reduced market value and, therefore, the cost basis is adjusted to the lower of cost or market. Typically, market values for excess or obsolete inventories are considered to be zero. Inventory charges recorded in fiscal year 2015 for excess and obsolete inventory, including scrapped inventory, amounted to $7.2 million, primarily associated with a customer build forecast that exceeded actual market demand, resulting in excess inventory levels for certain high volume products. No significant inventory charges were recorded in fiscal year 2014.

Inventories were comprised of the following (in thousands):



	March 28,		March 29,
	2015		2014
Work in process	$	64,663	$	37,967
Finished goods		19,533		31,776
	$	84,196	$	69,743

Property, Plant and Equipment, net

Property, plant and equipment is recorded at cost, net of depreciation and amortization. Depreciation and amortization is calculated on a straight-line basis over estimated economic lives, ranging from three to 39 years. Leasehold improvements are depreciated over the shorter of the term of the lease or the estimated useful life. Furniture, fixtures, machinery, and equipment are all depreciated over a useful life of three to 10 years, while buildings are depreciated over a period of up to 39 years. In general, our capitalized software is amortized over a useful life of three years, with capitalized enterprise resource planning software being amortized over a useful life of 10 years. Gains or losses related to retirements or dispositions of fixed assets are recognized in the period incurred.

Property, plant and equipment was comprised of the following (in thousands):



	March 28,		March 29,
	2015		2014

Less: Accumulated depreciation and amortization		(72,359)		(57,668)
Property, plant and equipment, net	$	144,346	$	103,650

Depreciation and amortization expense on property, plant, and equipment for fiscal years 2015, 2014, and 2013, was $15.4 million, $12.1 million, and $10.2 million, respectively.

Goodwill and Intangibles, net

Intangible assets include purchased technology licenses and patents that are reported at cost and are amortized on a straight-line basis over their useful lives, generally ranging from one to ten years. Acquired intangibles include existing technology, core technology or patents, license agreements, trademarks, tradenames, and customer relationships. These assets are amortized on a straight-line basis over lives ranging from one to fifteen years.

Goodwill is recorded at the time of an acquisition and is calculated as the difference between the aggregate consideration paid for an acquisition and the fair value of the net tangible and intangible assets acquired. Goodwill and intangible assets deemed to have indefinite lives are not amortized but are subject to annual impairment tests. If the assumptions and estimates used to allocate the purchase price are not correct, or if business conditions change, purchase price adjustments or future asset impairment charges could be required. The value of our intangible assets, including goodwill, could be impacted by future adverse changes such as: (i) any future declines in our operating results, (ii) a decline in the valuation of technology company stocks, including the valuation of our common stock, (iii) a significant slowdown in the worldwide economy and the semiconductor industry, or (iv) any failure to meet the performance projections included in our forecasts of future operating results. The Company tests goodwill and indefinite lived intangibles for impairment on an annual basis or more frequently if the Company believes indicators of impairment exist. Impairment evaluations involve management’s assessment of qualitative factors to determine whether it is more likely than not that goodwill and other intangible assets are impaired. If management concludes from its assessment of qualitative factors that it is more likely than not that impairment exists, then a quantitative impairment test will be performed involving management estimates of asset useful lives and future cash flows. Significant management judgment is required in the forecasts of future operating results that are used in these evaluations. If our actual results, or the plans and estimates used in future impairment analyses, are lower than the original estimates used to assess the recoverability of these assets, we could incur additional impairment charges in a future period. The Company has recorded no goodwill impairments in fiscal years 2015, 2014 and 2013. There were no material intangible asset impairments in fiscal years 2015, 2014, or 2013.

Long-Lived Assets

We test for impairment losses on long-lived assets and definite-lived intangibles used in operations when indicators of impairment are present and the undiscounted cash flows estimated to be generated by those assets are less than the assets’ carrying amounts. We measure any impairment loss by comparing the fair value of the asset to its carrying amount. We estimate fair value based on discounted future cash flows, quoted market prices, or independent appraisals.

Foreign Currency Translation

All of our international subsidiaries have the U.S. dollar as the functional currency. The local currency financial statements are translated into U.S. dollars using current rates of exchange for assets and liabilities. Gains and losses from remeasurement are included in other expense.

Hedging and Forwards

Hedging and forward contracts are accounted for based upon the provisions of Accounting Standards Codification (“ASC) Topic 815, “Derivatives and Hedging” and ASC Topic 820, “Fair Value Measurements and Disclosures.”

All derivative instruments shall be carried at fair value per ASC 820. If a derivative instrument meets certain hedge accounting criteria, the provisions of ASC 815 may be applied. The Company regularly reviews all financial instruments and contracts. When a derivative is identified, it is evaluated against the criteria in ASC 815 to determine the appropriate accounting methodology. Derivatives that qualify for hedge accounting per ASC 815 are classified as one of the following: fair value hedge, cash flow hedge or foreign currency hedge.

Pension

Defined benefit pension plans are accounted for based upon the provisions of ASC Topic 715, “Compensation – Retirement Benefits.”

The funded status of the plan is recognized in the consolidated balance sheets. Subsequent re-measurement of plan assets and benefit obligations, if deemed necessary, would be reflected in the consolidated balance sheets in the subsequent interim period to reflect the overfunded or underfunded status of the plan.

The Company will engage external actuaries on at least an annual basis to provide a valuation of the plan’s assets and projected benefit obligation and to record the net periodic pension cost. On a quarterly basis, the Company will evaluate current information available to us to determine whether the plan’s assets and projected benefit obligation should be re-measured.

Concentration of Credit Risk

Financial instruments that potentially subject us to material concentrations of credit risk consist primarily of cash equivalents, marketable securities, long-term marketable securities, and trade accounts receivable. We are exposed to credit risk to the extent of the amounts recorded on the balance sheet. By policy, our cash equivalents, marketable securities, and long-term marketable securities are subject to certain nationally recognized credit standards, issuer concentrations, sovereign risk, and marketability or liquidity considerations.

In evaluating our trade receivables, we perform credit evaluations of our major customers’ financial condition and monitor closely all of our receivables to limit our financial exposure by limiting the length of time and amount of credit extended. In certain situations, we may require payment in advance or utilize letters of credit to reduce credit risk. By policy, we establish a reserve for trade accounts receivable based on the type of business in which a customer is engaged, the length of time a trade account receivable is outstanding, and other knowledge that we may possess relating to the probability that a trade receivable is at risk for non-payment.

We had two contract manufacturers, Hongfujin Precision and Protek, who represented 26 percent and 15 percent, respectively, and one direct customer, Samsung Electronics who represented 22 percent of our consolidated gross trade accounts receivable as of the end of fiscal year 2015. For fiscal year 2014, we had three contract manufacturers, Futaihua Industrial, Hongfujin Precision and Protek who represented 14 percent, 44 percent, and 12 percent, respectively, of our consolidated gross trade accounts receivable. Additionally, in fiscal year 2014, we had one distributor, Avnet, Inc. who represented 11 percent of our consolidated gross trade accounts receivable. No other distributor or customer had receivable balances that represented more than 10 percent of consolidated gross trade accounts receivable as of the end of fiscal year 2015 or 2014.

Since the components we produce are largely proprietary and generally not available from second sources, we consider our end customer to be the entity specifying the use of our component in their design. These end customers may then purchase our products directly from us, from a distributor, or through a third party manufacturer contracted to produce their end product. For fiscal years 2015, 2014, and 2013, our ten largest end customers represented approximately 87 percent, 88 percent, and 89 percent, of our sales, respectively. For fiscal years 2015, 2014, and 2013, we had one end customer, Apple Inc., who purchased through multiple contract manufacturers and represented approximately 72 percent, 80 percent, and 82 percent, of the Company’s total sales, respectively. No other customer or distributor represented more than 10 percent of net sales in fiscal years 2015, 2014, or 2013.

Revenue Recognition

We recognize revenue when all of the following criteria are met: persuasive evidence that an arrangement exists, delivery of goods has occurred, the sales price is fixed or determinable and collectability is reasonably assured. We evaluate our distributor arrangements, on a distributor by distributor basis, with respect to each of the four criteria above. For a majority of our distributor arrangements, we provide rights of price protection and stock rotation. As a result, revenue is deferred at the time of shipment to our domestic distributors and certain international distributors due to the determination that the ultimate sales price to the distributor is not fixed or determinable. Once the distributor has resold the product, and our final sales price is fixed or determinable, we recognize revenue for the final sales price and record the related costs of sales. For certain of our smaller international distributors, we do not grant price protection rights and provide minimal stock rotation rights. For these distributors, revenue is recognized upon delivery to the distributor, less an allowance for estimated returns, as the revenue recognition criteria have been met upon shipment.

Further, for sales where revenue is deferred, the Company defers the associated cost of goods sold on our Consolidated Balance Sheet, net within the deferred income caption. The Company routinely evaluates the products held by our distributors for impairment to the extent such products may be returned by the distributor within these limited rights and such products would be considered excess or obsolete if included within our own inventory. Products returned by distributors and subsequently scrapped have historically been immaterial to the Company.

Warranty Expense

We warrant our products and maintain a provision for warranty repair or replacement of shipped products. The accrual represents management’s estimate of probable returns. Our estimate is based on an analysis of our overall sales volume and historical claims experience. The estimate is re-evaluated periodically for accuracy.

Shipping Costs

Our shipping and handling costs are included in cost of sales for all periods presented in the Consolidated Statements of Income.

Advertising Costs

Advertising costs are expensed as incurred. Advertising costs were $1.1 million, $1.4 million, and $1.5 million, in fiscal years 2015, 2014, and 2013, respectively.

Stock-Based Compensation

Stock-based compensation is measured at the grant date based on the grant-date fair value of the awards and is recognized as an expense, on a ratable basis, over the vesting period, which is generally between zero and four years. Determining the amount of stock-based compensation to be recorded requires the Company to develop estimates used in calculating the grant-date fair value of stock options and performance awards (also called market stock units). The Company calculates the grant-date fair value for stock options and market stock units using the Black-Scholes valuation model and the Monte Carlo simulation, respectively. The use of valuation models requires the Company to make estimates of assumptions such as expected volatility, expected term, risk-free interest rate, expected dividend yield, correlation of the Company’s stock price with the Philadelphia Semiconductor Index (“the Index”) and forfeiture rates. The grant-date fair value of restricted stock units is the market value at grant date multiplied by the number of units.

Income Taxes

We provide for the recognition of deferred tax assets if realization of such assets is more likely than not. The Company evaluates the ability to realize its deferred tax assets based on all the facts and circumstances, including projections of future taxable income and expiration dates of carryover attributes on a quarterly basis. The calculation of our tax liabilities involves assessing uncertainties with respect to the application of complex tax rules and the potential for future adjustment of our uncertain tax positions by the Internal Revenue Service or other taxing jurisdiction. We recognize liabilities for uncertain tax positions based on the two-step process. The first step requires us to determine if the weight of available evidence indicates that the tax position has met the threshold for recognition; therefore, we must evaluate whether it is more likely than not that the position will be sustained on audit, including resolution of any related appeals or litigation processes. The second step requires us to measure the tax benefit of the tax position taken, or expected to be taken, in an income tax return as the largest amount that is more than 50 percent likely of being realized upon ultimate settlement. We reevaluate the uncertain tax positions each quarter based on factors including, but not limited to, changes in facts or circumstances, changes in tax law, expirations of statutes of limitation, effectively settled issues under audit, and new audit activity. If our estimates of these taxes are greater or less than actual results, an additional tax benefit or charge will result.

Although we believe the measurement of our liabilities for uncertain tax positions is reasonable, we cannot assure that the final outcome of these matters will not be different than what is reflected in the historical income tax provisions and accruals. If additional taxes are assessed as a result of an audit or litigation, it could have a material effect on our income tax provision and net income in the period or periods for which that determination is made. We operate within multiple taxing jurisdictions and are subject to audit in these jurisdictions. These audits can involve complex issues which may require an extended period of time to resolve and could result in additional assessments of income tax. We believe adequate provisions for income taxes have been made for all periods.

Net Income Per Share

Basic net income per share is based on the weighted effect of common shares issued and outstanding and is calculated by dividing net income by the basic weighted average shares outstanding during the period. Diluted net income per share is calculated by dividing net income by the weighted average number of common shares used in the basic net income per share calculation, plus the equivalent number of common shares that would be issued assuming exercise or conversion of all potentially dilutive common shares outstanding. These potentially dilutive items consist primarily of outstanding stock options and restricted stock grants.

The following table details the calculation of basic and diluted earnings per share for fiscal years 2015, 2014, and 2013, (in thousands, except per share amounts):



	2015		2014		2013
Numerator:
Net income	$	55,178	$	108,111	$	136,598
Denominator:
Weighted average shares outstanding		62,503		62,926		64,580
Effect of dilutive securities		2,732		2,609		3,874
Weighted average diluted shares		65,235		65,535		68,454
Basic earnings per share	$	0.88	$	1.72	$	2.12
Diluted earnings per share	$	0.85	$	1.65	$	2.00

The weighted outstanding options excluded from our diluted calculation for the years ended March 28, 2015, March 29, 2014, and March 30, 2013 were 718 thousand, 833 thousand, and 453 thousand, respectively, as the exercise price exceeded the average market price during the period.

Accumulated Other Comprehensive Loss

Our accumulated other comprehensive loss is comprised of foreign currency translation adjustments from prior years when we had subsidiaries whose functional currency was not the U.S. Dollar, unrealized gains and losses on investments classified as available-for-sale and actuarial gains and losses on our pension plan assets. See Note 16 – Accumulated Other Comprehensive Loss for additional discussion.

Recently Issued Accounting Pronouncements

In August 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (“ASU”) No. 2014-15, Presentation of Financial Statements—Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern. The amendments in this ASU provide guidance in GAAP about management’s responsibility to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern and to provide related footnote disclosures. The amendments are effective for the annual period ending after December 15, 2016, and for annual periods and interim periods thereafter. Early application is permitted. The Company is currently evaluating the impact of this ASU and expects no material modifications to its financial statements.

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (ASC Topic 606). The purpose of this ASU is to converge revenue recognition requirements per GAAP and International Financial Reporting Standards (IFRS). The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The amendments in this ASU are effective for interim and annual reporting periods beginning after December 15, 2016, with early adoption not permitted by the FASB; however, in April 2015 the FASB issued for public comment a proposal to delay the effective date of this ASU to annual reporting periods beginning after December 15, 2017. The Company is currently evaluating the impact of this ASU on its consolidated financial position, results of operations and cash flows.

In April 2015, the FASB issued ASU No. 2015-03, Interest—Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs. The amendments in this update require that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability. ASU 2015-03 is to be applied retrospectively and represents a change in accounting principle. This ASU is effective for fiscal years beginning after December 15, 2015, including interim periods within those fiscal years. Earlier adoption is permitted for financial statements that have not been previously issued. The Company is currently evaluating the effect that the adoption of this ASU will have on its financial statements.
