Rest of the answer
GAAP requires our management to make judgments, assumptions and estimates that affect the amounts reported in our Consolidated Financial Statements and the accompanying notes. Our management bases its estimates and judgments on historical experience, current economic and industry conditions and on various other factors that are believed to be reasonable under the circumstances. Actual results may differ from these estimates under different assumptions or conditions.
The methods, estimates, and judgments that we use in applying our accounting policies have a significant impact on the results that we report in our consolidated financial statements. Some of our accounting policies require us to make difficult and subjective judgments, often as a result of the need to make estimates regarding matters that are inherently uncertain. Our most critical accounting estimates include:
• the valuation of inventory, which impacts gross margin;
the assessment of recoverability of goodwill, identified intangible assets and tangible fixed assets, which impacts gross margin or operating expenses when we record asset impairments or accelerate their depreciation or amortization;
revenue recognition, which impacts our results of operations;
the recognition of current and deferred income taxes (including the measurement of uncertain tax positions), which impacts our provision for income taxes;
the assumptions used in the determination of postretirement benefit obligations, which impacts operating expenses;
the assumptions used in the determination of share based compensation, which impacts gross margin and operating expenses; and the recognition and measurement of loss contingencies, which impacts gross margin or operating expenses when we recognize a loss contingency or revise the estimates for a loss contingency.
In the following section, we discuss these policies further, as well as the estimates and judgments involved.
Inventories
Inventories are valued at the lower of cost or market. We regularly review our inventories and write down our inventories for estimated losses due to obsolescence. This allowance is determined for groups of products based on sales of our products in the recent past and/or expected future demand. Future demand is affected by market conditions, technological obsolescence, new products and strategic plans, each of which is subject to change with little or no forewarning. In estimating obsolescence, we utilize information that includes projecting future demand.
The need for strategic inventory levels to ensure competitive delivery performance to our customers are balanced against the risk of inventory obsolescence due to rapidly changing technology and customer requirements.
The change in our reserves for inventories was primarily due to the normal review and accrual of obsolete or excess inventory. If actual future demand or market conditions are less favorable than those projected by our management, additional inventory write-downs may be required.
Goodwill
Goodwill is required to be tested for impairment at least annually or sooner whenever events or changes in circumstances indicate that the assets may be impaired. Such events or changes in circumstances can be significant changes in business climate, operating performance or competition, or upon the disposition of a significant portion of a reporting unit. A significant amount of judgment is involved in determining if an indicator of impairment has occurred between annual test dates. This impairment review compares the fair value for each reporting unit containing goodwill to its carrying value. Determining the fair value of a reporting unit involves the use of significant estimates and assumptions, including projected future cash flows, discount rates based on weighted average cost of capital and future economic and market conditions. We base our fair-value estimates on assumptions we believe to be reasonable. Actual cash flow amounts for future periods may differ from estimates used in impairment testing.
For the annual impairment assessment in 201X, we determined that for each of our reporting units, it was more likely than not that the fair value of the reporting units exceeded the carrying value. As a result, we concluded that performing the first step of the goodwill impairment test was not necessary for any reporting unit. During the fourth quarter of each of the prior two fiscal years, we have completed our annual impairment assessments and concluded that goodwill was not impaired in any of these years.
Impairment or disposal of identified intangible assets and tangible fixed assets
We perform reviews of property, plant and equipment, and certain identifiable intangibles, excluding goodwill, to determine if facts and circumstances indicate that the useful life is shorter than what we had originally estimated or that the carrying amount of assets may not be recoverable. If such facts and circumstances exist, we assess the recoverability of the long-lived assets by comparing the projected undiscounted net cash flows associated with the related asset or group of assets over their remaining lives against their respective carrying amounts. In the event such cash flows are not expected to be sufficient to recover the recorded value of the assets, the assets are written down to their estimated fair values based on the expected discounted future cash flows attributable to the assets or based on appraisals. Impairment losses, if any, are based on the excess of the carrying amount over the fair value of those assets.
The assumptions and estimates used to determine future values and remaining useful lives of our intangible and other long-lived assets are complex and subjective. They can be affected by various factors, including external factors such as industry and economic trends, and internal factors such as changes in our business strategy and our forecasts for specific product lines. No impairment or disposal of identified intangible assets and tangible fixed assets were required to be recognized in 201X, 201X and 201X.
Revenue recognition
The Company’s revenue is derived from sales to distributors, made-to-order sales to Original Equipment Manufacturers (“OEMs”) and similar customers.
Revenue is recognized when persuasive evidence of an arrangement exists, delivery has occurred or the service has been provided, the sales price is fixed or determinable, and collection is reasonably assured, based on the terms and conditions of the sales contract. For made-to-order sales, these criteria are met at the time the product is shipped and delivered to the customer and title and risk have passed to the customer. Acceptance of the product by the customer is generally not contractually required, since, for made-to-order customers, design approval occurs before manufacturing and subsequently delivery follows without further acceptance protocols. Payment terms used are those that are customary in the particular geographic market. When management has established that all aforementioned conditions for revenue recognition have been met and no further post-shipment obligations exist, revenue is recognized.
For sales to distributors, revenue is recognized upon sale to the distributor (sell-in accounting). We record reductions to sales associated with reserves for allowances for collectability, discounts, price protection, product returns and distributor incentive programs at the time the related sale is recognized. The establishment of such reserves is dependent on a variety of factors, including contractual terms, analysis of historical data, current economic conditions, industry demand and both the current and forecasted pricing environments.
The process of evaluating these factors is highly subjective and requires significant estimates, including, but not limited to, forecasted demand, returns, pricing assumptions and inventory levels. In future periods, additional provisions may be necessary due to a deterioration in the semiconductor pricing environment, reductions in anticipated demand for semiconductor products and/or lack of market acceptance for new products. If these factors result in a significant adjustment to our reserves, they could significantly impact our future operating results.
Distributor reserves estimate the impact of credits granted to distributors under certain programs common in the semiconductor industry whereby distributors receive certain price adjustments to meet individual competitive opportunities, or are allowed to return or scrap a limited amount of product in accordance with contractual terms agreed upon with the distributor, or receive price protection credits when our standard published prices are lowered from the price the distributor paid for product still in its inventory. The Company’s policy is to use a rolling historical experience rate, as well as a prospective view of products and pricing in the distribution channel for distributors who participate in our volume rebate incentive program, in order to estimate the proper provision for this program at the end of any given reporting period. We continually monitor the actual claimed allowances against our estimates, and we adjust our estimates as appropriate to reflect trends in pricing environments and inventory levels. Distributor reserves are also adjusted when recent historical data does not represent anticipated future activity.
Income taxes
Deferred tax assets and liabilities are recognized for the expected tax consequences of temporary differences between the tax basis of assets and liabilities and their reported amounts. Measurement of deferred tax assets and liabilities is based upon the enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. Deferred tax liabilities for withholding taxes on dividends from subsidiaries are recognized in situations where the company does not consider the earnings indefinitely reinvested and to the extent that these withholding taxes are not expected to be refundable.
Deferred tax assets, including assets arising from loss carryforwards, are recognized, net of a valuation allowance, if based upon the available evidence it is more likely than not that the asset will be realized.
The income tax benefit from an uncertain tax position is recognized only if it is more likely than not that the tax position will be sustained upon examination by the relevant taxing authorities. The income tax benefit recognized is measured based on the largest benefit that is more than 50% likely to be realized upon resolution of the uncertainty. Unrecognized tax benefits are presented as a reduction to the deferred tax asset for related net operating loss carryforwards, unless these would not be available, in which case the uncertain tax benefits are presented together with the related interest and penalties as a liability, under accrued liabilities and other non-current liabilities based on the timing of the expected payment. Penalties are recorded as income tax expense, whereas interest is reported as financial expense in the statement of operations.
Postretirement benefits
The Company’s employees participate in pension and other postretirement benefit plans in many countries. The costs of pension and other postretirement benefits and related assets and liabilities with respect to the Company’s employees participating in defined-benefit plans are based upon actuarial valuations.
The projected defined-benefit obligation is calculated annually by qualified actuaries using the projected unit credit method. For the
Company’s major plans, the discount rate is derived from market yields on high quality corporate bonds. Plans in countries without a deep corporate bond market use a discount rate based on the local government bond rates.
In calculating obligation and expense, the Company is required to select actuarial assumptions. These assumptions include discount rate, expected long-term rate of return on plan assets and rates of increase in compensation costs determined based on current market conditions, historical information and consultation with and input from our actuaries. Changes in the key assumptions can have a significant impact to the projected benefit obligations, funding requirements and periodic pension cost incurred. A sensitivity analysis is provided in note 15, “Postretirement Benefit Plans”.
The Company determines the fair value of plan assets based on quoted prices or comparable prices for non-quoted assets. For a defined-benefit pension plan, the benefit obligation is the projected benefit obligation; for any other postretirement defined benefit plan it is the accumulated postretirement benefit obligation.
Share-based compensation
We recognize compensation expense for all share-based awards based on the grant-date estimated fair values, net of an estimated forfeiture rate. We use the Black-Scholes option pricing model to determine the estimated fair value for certain awards. Share-based compensation cost for restricted share units (“RSU”s) with time-based vesting is measured based on the closing fair market value of our common stock on the date of the grant, reduced by the present value of the estimated expected future dividends, and then multiplied by the number of RSUs granted. Share-based compensation cost for performance-based share units
(“PSU”s) granted with performance or market conditions is measured using a Monte Carlo simulation model on the date of grant.
Our valuation models and generally accepted valuation techniques require us to make assumptions and to apply judgment to determine the fair value of our awards. These assumptions and judgments include estimating the volatility of our stock price, expected dividend yield, employee turnover rates and employee stock option exercise behaviors. Due to the lack of extensive history as a public company, the computation of the expected volatility assumptions used in the Black-Scholes calculations for grants was based on historical volatilities and implied volatilities of our peer group companies. When establishing the expected life assumption, we used the ‘simplified’ method prescribed in ASC Topic 718 for companies that do not have adequate historical data. The risk-free interest rate is measured as the prevailing yield for a U.S. Treasury security with a maturity similar to the expected life assumption. We also estimate a forfeiture rate at the time of grant and revise this rate in subsequent periods if actual forfeitures or vesting differ from the original estimates.
We evaluate the assumptions used to value our awards on a quarterly basis. If factors change and we employ different assumptions, share-based compensation expense may differ significantly from what we have recorded in the past. If there are any modifications or cancellation of the underlying unvested securities, we may be required to accelerate, increase or cancel any remaining unearned share-based compensation expense.
Litigation and claims
We are regularly involved as plaintiffs or defendants in claims and litigation relating to matters such as commercial transactions and intellectual property rights. In addition, our divestments sometimes result in, or are followed by, claims or litigation by either party. From time to time, we also are subject to alleged patent infringement claims. We rigorously defend ourselves against these alleged patent infringement claims, and we rarely participate in settlement discussions. There can be no assurance that the Company’s accruals will be sufficient to cover the extent of its potential exposure to losses. Historically, legal actions have not had a material adverse effect on the Company’s business, results of operations or financial condition.
The estimated aggregate range of reasonably possible losses is based on currently available information in relation to the claims that have arisen and on the Company’s best estimate of such losses for those cases for which such estimate can be made. For certain claims, the Company believes that an estimate cannot currently be made. The estimated aggregate range requires significant judgment, given the varying stages of the proceedings (including the fact that many of them are currently in preliminary stages), the existence of multiple defendants (including the Company) in such claims whose share of liability has yet to be determined, the numerous yet-unresolved issues in many of the claims, and the attendant uncertainty of the various potential outcomes of such claims. Accordingly, the Company’s estimate will change from time to time, and actual losses may be more than the current estimate.
