SIGNIFICANT  ACCOUNTING  POLICIES





Interim Financial Information -The accompanying condensed consolidated financial statements of Micrel, Incorporated and its wholly-owned subsidiaries (“Micrel” or the “Company”) as of March 31, 2010 and for the three months ended March 31, 2010 and 2009 are unaudited. In the opinion of management, the condensed consolidated financial statements include all adjustments (consisting only of normal recurring accruals) that management considers necessary for a fair statement of its financial position, operating results and cash flows for the interim periods presented. Operating results and cash flows for interim periods are not necessarily indicative of results for the entire year. The Condensed Consolidated Balance Sheet as of December 31, 2009, was derived from audited financial statements, but does not include all disclosures required by accounting principles generally accepted ("GAAP") in the United States of America. These financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2009. These financial statements should also be read in conjunction with the Company's critical accounting policies included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2009 and those included in this Form 10-Q below.





Net Income Per Common and Equivalent Share-Basic net income per share is computed by dividing net income by the number of weighted-average common shares outstanding. Diluted net income per share reflects potential dilution from outstanding stock options using the treasury stock method. Reconciliation of weighted-average shares used in computing net income per share is as follows (in thousands):

66,175Dilutive effect of stock options outstanding using the treasury stock method

48Shares used in computing diluted net income per share


62,548



66,223





For the three months ended March 31, 2010 and 2009, 3.8 million and 8.4 million stock options, respectively, have been excluded from the weighted-average number of common shares outstanding for the diluted net income per share computations as they were anti-dilutive.








2.
RECENTLY ISSUED ACCOUNTING STANDARDS





In January 2010, the FASB issued updated guidance related to fair value measurements and disclosures, which requires a reporting entity to disclose separately the amounts of significant transfers in and out of Level 1 and Level 2 fair value measurements and to describe the reasons for the transfers. In addition, in the reconciliation for fair value measurements using significant unobservable inputs, or Level 3, a reporting entity should disclose separately information about purchases, sales, issuances and settlements (that is, on a gross basis rather than one net number). The updated guidance also requires that an entity should provide fair value measurement disclosures for each class of assets and liabilities and disclosures about the valuation techniques and inputs used to measure fair value for both recurring and non-recurring fair value measurements for Level 2 and Level 3 fair value measurements. The Company adopted updated guidance on January 1, 2010, except for the disclosures about purchases, sales, issuances and settlements in the roll forward activity in Level 3 fair value measurements, which are effective for fiscal years beginning after December 15, 2010 and for interim periods within those fiscal years. The adoption of the updated guidance had no impact on the Company’ consolidated results of operations or financial condition.

SHARE-BASED COMPENSATION





Share-based compensation is measured at the grant date, based on the fair value of the award and is recognized over the employee's requisite service period. For further details regarding the Company's share-based compensation arrangements, refer to Note 7 of Notes to Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2009. The following table summarizes total share-based compensation expense included in the Condensed Consolidated Statement of Operations:

During the three months ended March 31, 2010 and 2009, the Company granted 712,727 and 274,000 stock options, respectively, at weighted average fair values of $3.73 and $2.87 per share, respectively. The fair value of the Company’s stock options granted under the Company’s option plans was estimated at the date of grant using the Black-Scholes option pricing model with the following weighted-average assumptions:

As of March 31, 2010, there was $13.2 million of total unrecognized share-based compensation related to non-vested stock option awards which is expected to be recognized over a weighted-average period of 3.8 years. Total share-based compensation capitalized as part of inventory as of March 31, 2010 and December 31, 2009 was $117,000 and $145,000, respectively.








4.
INVESTMENTS





Investments purchased with remaining maturity dates of greater than three months and less than 12 months are classified as short-term. Investments purchased with remaining maturity dates of 12 months or greater are classified either as short-term or as long-term based on maturities and the Company's intent with regard to those securities (expectations of sales and redemptions). Short-term investments as of March 31, 2010 consist of certificates of deposit and are classified as available-for-sale securities. Long-term investments as of March 31, 2010 consist of auction rate notes secured by student loans and are classified as available-for-sale securities. Available-for sale securities are stated at market value with unrealized gains and losses included in shareholders’ equity. Unrealized losses are charged against income when a decline in the fair market value of an individual security is determined to be other than temporary. Realized gains and losses on investments are included in other income or expense.

To determine the fair value of financial instruments, the Company uses a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (level 1 measurements) and the lowest priority to unobservable inputs (level 3 measurements). The three levels of the fair value hierarchy are described below:




•
Level 1 - Quoted prices in active markets for identical assets or liabilities.
 •
Level 2 - Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
 •
Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.


A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Most of the Company’s financial instruments are classified within Level 1 or Level 2 of the fair value hierarchy because they are valued using quoted market prices, broker or dealer quotations, or alternative pricing sources with reasonable levels of price transparency.





The types of instruments valued based on quoted market prices in active markets include money market funds and commercial paper. Such instruments are generally classified within Level 1 of the fair value hierarchy. The types of instruments valued based on other observable inputs include U.S. agency securities. Such instruments are generally classified within Level 2 of the fair value hierarchy. The types of instruments valued based on unobservable inputs include the auction rate securities held by the Company. Such instruments are generally classified within Level 3 of the fair value hierarchy. The Company estimated the fair value of these auction rate securities using a discounted cash flow model incorporating assumptions that market participants would use in their estimates of fair value. Some of these assumptions include estimates for interest rates, timing and amount of cash flows and expected holding periods of the auction rate securities.





Financial assets and liabilities measured at fair value on a recurring basis as of March 31, 2010 were as follows (in thousands):

As of March 31, 2010, the Company had approximately $12.5 million of auction rate notes, the fair value of which has been measured using Level 3 inputs. Auction rate notes are securities that are structured with short-term interest rate reset dates of generally less than ninety days, but with contractual maturities that can be in excess of ten years. At the end of each reset period, which occurs every seven or twenty eight days for the securities held by the Company, investors can sell or continue to hold the securities at par. During the first quarter of 2008 and continuing through the first quarter of 2010, the auction rate securities market experienced a significant increase in the number of failed auctions, which occurs when sell orders exceed buy orders. Auctions for the student loan-backed notes held by the Company failed as of March 31, 2010. To date the Company has collected all interest payable on all of its auction-rate securities when due and expects to continue to do so in the future. The principal associated with failed auctions will not be accessible until a successful auction occurs, a buyer is found outside of the auction process, the issuers redeem the securities, the issuers repay principal over time from cash flows prior to final maturity or final payments come due according to contractual maturities ranging from 23 to 36 years. As a result, the Company has classified all auction rate notes as long-term investments as of March 31, 2010 and December 31, 2009. In the event of a failed auction, the notes bear interest at a predetermined maximum rate based on the credit rating of notes as determined by one or more nationally recognized statistical rating organizations. For the auction rate notes held by the Company as of March 31, 2010, the maximum interest rate is generally one month LIBOR plus 1.5% based on the notes’ AAA rating as of that date.





The Company has used a combination of discounted cash flow models and observable transactions for similar securities to determine the estimated fair value of its investment in auction rate notes as of March 31, 2010 and December 31, 2009. The assumptions used in preparing the discounted cash flow model include estimates for interest rates, estimates for discount rates using yields of comparable traded instruments adjusted for illiquidity and other risk factors, amount of cash flows and expected holding periods of the auction rate notes. Based on this assessment of fair value as of March 31, 2010, the Company determined there was a cumulative decline in the fair value of its auction rate notes of approximately $2.7 million (recorded net of tax as an unrealized loss in accumulated other comprehensive loss). As of March 31, 2010, the fair value of the Company’s auction rate notes have been in an unrealized loss position for greater than 12 months. The Company has deemed the unrealized loss to be temporary as the Company believes it will recover its cost basis in these investments.





For the three months ended March 31, 2010, the changes in the Company’s Level 3 securities (consisting of auction rate notes) are as follows (in thousands):

Interest under the line of credit facility will accrue based on one of three interest rates, at the Company’s option: (1) a variable alternate base rate plus 1.00%, the alternate base rate being the greater of (x) Bank of the West’s prime rate, (y) the Fed Funds Rate plus 0.5% or (z) daily adjusted one-month LIBOR plus 1.00%; (2) floating one-month LIBOR plus 2.25% or (3) fixed LIBOR for one, two, three or six month periods, plus 2.25%.





The agreement includes certain restrictive covenants and, as of March 31, 2010, the Company was in compliance with such covenants.





The credit facility also includes a $15 million term loan facility to finance the repurchase of shares of the Company’s common stock. In May 2009, the Company borrowed $15 million under the term loan. Interest under the term loan facility is payable at a rate equal to floating one-month LIBOR plus 2.25%. Borrowings are payable over 21 equal monthly installments, which commenced on August 31, 2009. The following table summarizes the Company’s long-term debt (in thousands):

DERIVATIVE FINANCIAL INSTRUMENTS





In June 2009, the Company entered into an interest rate swap contract (the “Swap”), to partially offset its exposure to the effects of changes in interest rates on its variable-rate financing obligations. As a result of entering into the Swap, the Company has economically hedged the variability on future interest payments resulting in a fixed rate of 3.36% for $4.6 million of the Company’s notes payable as of March 31, 2010 (see Note 9). The Company will experience variability in future interest payments for the remaining $4.6 million unhedged portion of the Company’s notes payable. The Company does not hold derivative financial instruments for trading or speculative purposes. The Swap is considered a cash flow hedge.





For derivative instruments that are designated and qualify as a cash flow hedge, the effective portion of the gain or loss on the derivative is reported as a component of other comprehensive income and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. Gains and losses on the derivative representing either hedge ineffectiveness or hedge components excluded from the assessment of effectiveness are recognized in current earnings.





All derivatives are recorded at fair value in either prepaid and other current assets or other accrued liabilities. The Company reports cash flows from derivative instruments in cash flows from operating activities. As of March 31, 2010, the notional amount of the outstanding interest rate swap contract was $4.6 million. The effect of derivative instruments on the Statement of Operations for the three months ended March 31, 2010 was not material. The fair values of the Company’s derivative assets and liabilities as of March 31, 2010 and December 31, 2009, were not material. The Company will continue to revaluate the fair value of the derivative instrument at each period end and record corresponding impact on the balance sheet and Statement of Operations.

SIGNIFICANT CUSTOMERS





During the three months ended March 31, 2010, two customers accounted for more than 10% of net revenues. Two worldwide distributors accounted for $14.2 million (21%) and $12.8 million (19%) of net revenues, respectively. During the three months ended March 31, 2009, three customers accounted for more than 10% of net revenues. An original equipment manufacturer accounted for $5.7 million (12%) and two worldwide distributors accounted for $8.0 million (17%) and $6.7 million (14%) of net revenues, respectively.





As of March 31, 2010, two worldwide distributors accounted for 26% and 18%, respectively, of total accounts receivable. At December 31, 2009, three world-wide distributors and an original equipment manufacturer accounted for 19%, 18%, 10% and 11%, respectively, of total accounts receivable.

SEGMENT REPORTING





Operating segments are identified as components of an enterprise about which separate discrete financial information is available for evaluation by the chief operating decision maker. The Company has two reportable segments: standard products and other products, which consist primarily of custom and foundry products and revenues from the license of patents. The chief operating decision maker evaluates segment performance based on revenue. Accordingly, all expenses are considered corporate level activities and are not allocated to segments. Therefore, it is not practical to show profit or loss by reportable segments. Also, the chief operating decision maker does not assign assets to these segments. Consequently, it is not relevant to show assets by reportable segments.

LITIGATION AND OTHER CONTINGENCIES





From time to time, claims have been filed by or have arisen against the Company in its normal course of business. The Company believes that the ultimate resolution of these claims and lawsuits will not have a material adverse effect on the Company's financial condition, results of operations or cash flows.





As of March 31, 2010, the Company believes it is not reasonably likely that an unrecorded material loss has been incurred. Generally, litigation is subject to inherent uncertainties, and no assurance can be given that the Company will prevail in any particular lawsuit. Accordingly, the pending lawsuits, as well as potential future litigation with other companies, could result in substantial costs and diversion of resources and could have a material adverse effect on the Company’s financial condition, results of operations or cash flows.








15.
SHARE REPURCHASE PROGRAM





On February 5, 2010, the Company's Board of Directors approved a $15 million share repurchase program for calendar year 2010. Share repurchases are recorded as a reduction of common stock to the extent available. Any amounts in excess of common stock are recorded as a reduction of retained earnings. Shares of common stock purchased pursuant to the repurchase program are cancelled from outstanding shares upon repurchase and credited to an authorized and un-issued reserve account. Share repurchases are intended to reduce the number of outstanding shares of common stock to increase shareholder value and offset dilution from the Company's stock option plans and employee stock purchase plan. During the three months ended March 31, 2010, the Company repurchased 115,017 shares of its common stock for an aggregate price of $967,000.

INCOME TAXES





The income tax provision for the three months ended March 31, 2010, as a percentage of income before taxes, was 35.5%. The tax provision for this period excludes approximately 1.5% in benefits, as a percentage of income before taxes, from the Federal research and development credit which expired on December 31, 2009. The tax provision for the three months ended March 31, 2009, as a percentage of income before taxes, was 40.8%. The tax provision for this period included an additional $240,000 to reduce the amount of non-current deferred tax assets that were determined to be unrealizable due to California tax law changes in that period.





As of March 31, 2010, the gross liability for uncertain tax positions was $9.7 million and the net liability, reduced for the federal effects of potential state tax exposures, was $6.9 million. If these uncertain tax positions are sustained upon tax authority audit, or otherwise become certain, the net $6.9 million would favorably affect the Company’s tax provision in such future periods. Included in the $6.9 million is $2.0 million which has not yet reduced income tax payments, and, therefore, has been netted against non-current deferred tax assets. The remaining $4.9 million liability is included in long-term income taxes payable. The Company does not anticipate a significant change to the net liability for uncertain income tax positions within the next 12 months.





The Company continues to recognize interest and penalties related to income tax matters as part of the income tax provision. As of March 31, 2010 and December 31, 2009, the Company had $541,000 and $478,000, respectively, accrued for interest and $0 accrued for penalties for both periods. These accruals are included as a component of long-term income taxes payable.





The Company is required to file U.S. federal income tax returns as well as income tax returns in various states and foreign jurisdictions. The Company may be subject to examination by the Internal Revenue Service (“IRS”) for calendar years 2006 and forward. Significant state tax jurisdictions include California, New York and Texas, and generally, the Company is subject to routine examination for years 2005 and forward in these jurisdictions. In addition, any research and development credit carryforwards that were generated in prior years and utilized in these years may also be subject to examination by respective state taxing authorities. Generally, the Company is subject to routine examination for years 2002 and forward in various immaterial foreign tax jurisdictions in which it operates.





Deferred tax assets and liabilities result primarily from temporary differences between book and tax bases of assets and liabilities and state research and development credit carryforwards. The Company had net current deferred tax assets of $20.9 million and net long-term deferred tax assets of $9.9 million as of March 31, 2010. The Company must regularly assess the likelihood that future taxable income levels will be sufficient to ultimately realize the tax benefits of these deferred tax assets. The Company currently believes that future taxable income levels will be sufficient to realize the tax benefits of these deferred tax assets and has not established a valuation allowance. Should the Company determine that future realization of these tax benefits is not likely, a valuation allowance would be established, which would increase the Company's tax provision in the period of such determination.

DIVIDENDS





On January 28, 2010, the Company’s Board of Directors declared a cash dividend of $0.035 per outstanding share of common stock. The payment of $2.1 million was made on February 24, 2010 to shareholders of record as of February 10, 2010.

 MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (CONTINUED)


In addition to standard analog and mixed signal products, Micrel offers customers various combinations of design, process and foundry services.
 To enhance the readers' understanding of the Company's performance, the following chronological overview of the Company's results for the quarterly periods from January 1, 2009 through March 31, 2010 has been provided.


The worldwide macroeconomic recession continued to impact demand in the first quarter of 2009 and the Company’s customers continued to maintain lean inventory levels. Despite the difficult environment, first quarter of 2009 bookings increased over fourth quarter levels and resulted in a book to bill ratio above one for both the OEM and distribution sales channels. The Company’s first quarter of 2009 revenues were $47.0 million, compared to $55.2 million in the fourth quarter of 2008. First quarter 2009 gross margin was 50.3%, compared to 52% in the prior quarter. The decrease in gross margin was primarily the result of factory capacity under-utilization as Micrel continued to control its inventory levels. First quarter 2009 net income was $1.5 million, or $0.02 per diluted share, as compared to fourth quarter 2008 net income of $4.9 million, or $0.07 per diluted share. The Company maintained its quarterly three and one-half cent per share dividend and repurchased 1.9 million shares under its stock repurchase plan.





Despite a continuing weak economic environment, the Company experienced strong growth of both revenues and net income in the second quarter of 2009. Bookings were solid which resulted in a book-to-bill ratio above one. Second quarter revenues grew on a sequential quarter basis for the first time in four quarters. The Company saw strength in all major segments of its business with primary growth coming from markets in China. In particular, the build out of China’s 3G infrastructure was an important driver for the Company’s revenue growth in the second quarter of 2009. Revenues increased to $51.8 million in the second quarter of 2009, compared to $47.0 million in the first quarter of 2009. Second quarter 2009 operating expenses were down by 4% sequentially. Second quarter 2009 net income of $3.9 million was more than double the net income of $1.5 million reported for the first quarter of 2009. The Company continued to enhance shareholder value with its stock buy-back program. Average shares outstanding in the second quarter of 2009 decreased by 4% compared to the first quarter of 2009. In addition, the Company also maintained its quarterly three and one-half cent per share dividend payment.





Revenues for the third quarter of 2009 totaled $58.9 million, compared to $51.8 million in the second quarter of 2009, and $67.6 million in the third quarter of 2008. Sequential revenue growth was driven by increasing demand across most major markets served by the Company, especially from the industrial, handset and automotive markets. Bookings for the third quarter of 2009 were solid and the book-to-bill ratio was above one for the third quarter in a row. Third quarter 2009 gross margin improved to 52.5%, up from 51.3% in the second quarter of 2009, due to increased revenue levels to cover fixed manufacturing costs. Third quarter 2009 net income increased 76% to $6.8 million, or 11 cents per diluted share as compared to $3.9 million, or $0.06 per diluted share in the second quarter of 2009. As a result of the Company’s ongoing expense management and the Company’s stock repurchase program, third quarter 2009 earnings per diluted share of $0.11 were the same as the third quarter 2008 earnings per diluted share, despite significantly lower revenues in the third quarter of 2009 as compared to the third quarter of 2008. The Company also maintained its quarterly three and one-half cent per share dividend.





During the fourth quarter of 2009, ordering strength from the industrial and communications end markets resulted in a book-to-bill ratio significantly above one. Revenues in the fourth quarter of 2009 increased 4% to $61.2 million, compared to $58.9 million in the third quarter of 2009. The sequential growth was driven by increasing demand across most major markets for the Company’s products. Fourth quarter 2009 gross margin was 53.3%, up from 52.5% in the third quarter of 2009. The improvement in gross margin was due to better capacity utilization as a result of increased revenue levels to cover fixed manufacturing costs. During the quarter, total operating expenses included a $6.5 million non-cash, pre-tax charge related to the impairment of certain semiconductor manufacturing equipment located at the Company’s San Jose fabrication facility. Fourth quarter 2009 operating income was $5.5 million, or 8.9% of sales. This compares to operating income of $10.0 million, or 17.0% of sales in the third quarter 2009. Fourth quarter 2009 net income was $4.1 million, or $0.07 per basic and diluted share, which included a $0.06 per diluted share reduction due to the equipment impairment. This compares with third quarter 2009 net income of $6.8 million, or $0.11 per basic and diluted share. In addition, the Company continued to maintain its quarterly three and one-half cent per share dividend.

 MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (CONTINUED)





Micrel’s financial performance for 2009 continued to be strong, especially when considering the challenging macroeconomic environment experienced during 2009. The Company maintained its track record of profitability for 30 out of 31 years. For the year ended December 31, 2009, revenue was $218.9 million, compared to revenue of $259.4 million in 2008. Net income for 2009 was $16.3 million, or $0.26 per diluted share, compared with net income of $28.3 million, or $0.40 per diluted share in 2008. During 2009, Micrel generated $37.6 million in cash flow from operations; repurchased $32.5 million of its common stock; purchased its San Jose California corporate facility for approximately $6 million; paid $8.9 million of dividends to shareholders and made other capital investments of $6.1 million.





During the first quarter of 2010, demand from customers serving the industrial and communications end markets resulted in strong bookings and solid revenue growth as the Company continued to participate in the recovery of the semiconductor industry. During the first quarter of 2010, the Company’s book-to-bill ratio was significantly above one. Revenues increased to $67.2 million, representing a 9.7% increase above the $61.2 million reported for the fourth quarter of 2009. Compared to the same period last year, revenues were higher by $20.2 million, or 43.0%, due to higher overall demand from customers in all geographies and end markets. This marked the fourth consecutive quarter of revenue growth. First quarter 2010 gross margin was 55.4%, which also marks the fourth quarter in a row of sequential gross margin improvement for the Company. The Company’s operating margin of 22.2% in the first quarter of 2010 increased significantly from recent prior periods. First quarter 2010 net income of $9.7 million, or $0.16 per diluted share, increased from fourth quarter 2009 net income of $4.1 million, or $0.07 per diluted share. Fourth quarter 2009 earnings per share included $0.06 per diluted share of equipment impairment expense. During the first quarter of 2010, the Company generated $17.9 million in cash flow from operations. The Company also maintained its quarterly three and one-half cent per share dividend.





The Company derives a substantial portion of its net revenues from standard products. For the three months ended March 31, 2010 and 2009, the Company's standard products sales accounted for 97% of the Company's net revenues. The Company believes that a substantial portion of its net revenues in the future will depend upon standard products sales, although such sales as a proportion of net revenues may vary as the Company adjusts product output levels to correspond with varying economic conditions and demand levels in the markets which it serves. The standard products business is characterized by short-term orders and shipment schedules, and customer orders typically can be canceled or rescheduled without significant penalty to the customer. Since most standard products backlog is cancelable without significant penalty, the Company typically plans its production and inventory levels based on forecasts of customer demand, which is highly unpredictable and can fluctuate substantially. In addition, the Company is limited in its ability to reduce costs quickly in response to any revenue shortfalls.





The Company may experience significant fluctuations in its results of operations. Factors that affect the Company's results of operations include the volume and timing of orders received, changes in the mix of products sold, the utilization level of manufacturing capacity, competitive pricing pressures and the successful development and customer acceptance of new products. These and other factors are described in further detail later in this discussion and in Part II Item 1A. As a result of the foregoing or other factors, including the global economic crisis, there can be no assurance that the Company will not experience material fluctuations in future operating results on a quarterly or annual basis, which could materially and adversely affect the Company's business, financial condition, results of operations or cash flows.

Critical Accounting Policies and Estimates


The financial statements included in this Quarterly Report on Form 10-Q and discussed within this Management's Discussion and Analysis of Financial Condition and Results of Operations have been prepared in accordance with accounting principles generally accepted in the United States of America. Preparation of these financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. On an on-going basis, management evaluates its estimates and judgments. Management bases its estimates and judgments 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 results may differ from these estimates under different assumptions or conditions. The Company considers certain accounting policies related to revenue recognition and receivables, inventory valuation, share-based compensation, income taxes, and litigation to be critical to the fair presentation of its financial statements. For a detailed discussion of the Company's significant accounting policies, see Note 1 of Notes to Consolidated Financial Statements in Item 8 of the Company's Annual Report on Form 10-K for the year ended December 31, 2009.


Revenue Recognition and Receivables. Micrel generates revenue by selling products to OEMs, distributors and stocking representatives. Stocking representative firms may buy and stock the Company's products for resale or may act as the Company's sales representative in arranging for direct sales from the Company to an OEM customer. The Company's policy is to recognize revenue from sales to customers when the rights and risks of ownership have passed to the customer, when persuasive evidence of an arrangement exists, the product has been delivered, the price is fixed or determinable and collection of the resulting receivable is reasonably assured.





Micrel allows certain distributors located in North America and Europe, and in certain countries in Asia, significant return rights, price protection and pricing adjustments subsequent to the initial product shipment. As these returns and price concessions have historically been significant, and future returns and price concessions are difficult to reliably estimate, the Company defers recognition of revenue and related cost of sales (in the balance sheet line item “deferred income on shipments to distributors”) derived from sales to these distributors until they have resold the Company's products to their customers. Although revenue and related cost of sales are not recognized, the Company records an accounts receivable and relieves inventory at the time of initial product shipment. As standard terms are FOB shipping point, payment terms are enforced from shipment date and legal title and risk of inventory loss passes to the distributor upon shipment. In addition, where revenue is deferred upon shipment and recognized on a sell-through basis, the Company may offer price adjustments to its distributors to allow the distributor to price the Company's products competitively for specific resale opportunities. The Company estimates and records an allowance for distributor price adjustments for which the specific resale transaction has been completed, but the price adjustment claim has not yet been received and recorded by the Company.





Sales to OEM customers and stocking representatives are recognized based upon the shipment terms of the sale transaction when all other revenue recognition criteria have been met. The Company does not grant return rights, price protection or pricing adjustments to OEM customers. The Company offers limited contractual stock rotation rights to stocking representatives. In addition, the Company is not contractually obligated to offer, but may infrequently grant, price adjustments or price protection to certain stocking representatives on an exception basis. At the time of shipment to OEMs and stocking representatives, an allowance for returns is established based upon historical return rates, and an allowance for price adjustments is established based on an estimate of price adjustments to be granted. Actual future returns and price adjustments could be different than the allowance established.





The Company also maintains an allowance for doubtful accounts for estimated uncollectible accounts receivable. This estimate is based on an analysis of specific customer creditworthiness and historical bad debts experience. Actual future uncollectible amounts could exceed the doubtful accounts allowance established.

 MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (CONTINUED)





Inventory Valuation. Inventories are stated at the lower of cost (first-in, first-out method) or market. The Company records adjustments to write down the cost of obsolete and excess inventory to the estimated market value based on historical and forecasted demand for its products. If actual future demand for the Company's products is less than currently forecasted, additional inventory adjustments may be required. Once an inventory write-down provision is established, it is maintained until the product to which it relates is sold or otherwise disposed of.





Share-Based Compensation. Share-based compensation is measured at the grant date based on the fair value of the award and is recognized as expense in the statement of operations. To determine fair value, the Company uses the Black-Scholes valuation model which requires input factors such as expected term, stock price volatility, dividend yield and risk free interest rate. In addition, the Company estimates expected forfeiture rates of stock grants and share-based compensation expense is only recognized for those shares expected to vest. Determining the input factors, such as expected term, expected volatility and estimated forfeiture rates, requires significant judgment based on subjective future expectations.





Income Taxes.Deferred tax assets and liabilities result primarily from temporary timing differences between book and tax valuation of assets and liabilities, and state research and development credit carryforwards. The Company must regularly assess the likelihood that future taxable income levels will be sufficient to ultimately realize the tax benefits of these deferred tax assets. As of March 31, 2010, the Company believes that future taxable income levels will be sufficient to realize the tax benefits of these deferred tax assets and has not established a valuation allowance. Should the Company determine that future realization of these tax benefits is not more likely than not, a valuation allowance would be established, which would increase the Company's tax provision in the period of such determination.





The Company uses a two-step approach to recognize and measure uncertain tax positions. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount which is more than 50% likely of being realized upon ultimate settlement. The Company considers many factors when evaluating and estimating its tax positions and tax benefits, which may require periodic adjustments and which may not accurately anticipate actual outcomes.





Litigation.The semiconductor industry is characterized by frequent litigation regarding patent and other intellectual property rights. During recent years, the Company has resolved litigation involving intellectual property claims. An estimated liability is accrued when it is determined to be probable that a liability has been incurred and the amount of loss can be reasonably estimated. The liability accrual is charged to income in the period such determination is made. The Company regularly evaluates current information available to determine whether such accruals should be made.

Net Revenues. For the three months ended March 31, 2010, net revenues increased 43% to $67.2 million from $47.0 million for the same period in the prior year. This increase was the result of increased unit shipments across all product lines and geographies as the semiconductor industry began to recover from the worldwide macroeconomic recession. Standard products revenues for the three months ended March 31, 2010 increased 43% to $65.1 million from $45.6 million for the same period in the prior year. For the three months ended March 31, 2010, other products, which consist primarily of custom and foundry products revenues, increased 48% to $2.1 million compared to $1.4 million for the same period in the prior year.
 
 Customer demand for semiconductors can change quickly and unexpectedly. The Company’s revenue levels have been highly dependent on the amount of new orders that are received for which product is requested to be delivered to the customer within the same quarter. Within the semiconductor industry these orders that are booked and shipped within the quarter are called “turns fill” orders. When the turns fill level exceeds approximately 35% of quarterly revenue, it makes it very difficult to predict near term revenues and income. Because of the long cycle time to build its products, the Company’s lack of visibility into demand when turns fill is high makes it difficult to predict what product to build to match future demand.
 
 As noted in Part II Item 1A “Risk Factors” and above in the overview section of this “Management's Discussion and Analysis of Financial Condition and Results of Operations,” a trend has developed over the last several years whereby customers in the semiconductor supply chain have worked to minimize the amount of inventory of semiconductors they hold. As a consequence, customers are generally providing less order backlog to the Company and other semiconductor suppliers, and relying on short lead times to buffer their build schedules. Shorter lead times reduce visibility into end demand and increase the reliance on turns fill orders. The reluctance of customers to provide order backlog together with short lead times and the uncertain growth rate of the world economy, make it difficult to precisely predict future levels of sales and profitability.

Sales to customers in Asia represented 57% and 59%, respectively, of net revenues for the three months ended March 31, 2010 and 2009, respectively. The trend for the Company’s customers to move their electronics manufacturing to Asian countries has resulted in increased pricing pressure for Micrel and other semiconductor manufacturers. Asian based manufacturers are typically more concerned about cost and less concerned about the capability of the integrated circuits they purchase. This can make it more difficult for United States based companies to differentiate themselves in any manner other than by lowering prices. The increased concentration of electronics procurement and manufacturing in the Asia Pacific region has led, and may continue to lead, to continued price pressure for the Company’s products in the future.





Gross Profit. Gross profit is affected by a variety of factors including the volume of product sales, product mix, manufacturing capacity utilization, product yields and average selling prices. The Company's gross margin increased to 55.4% for the three months ended March 31, 2010 from 50.3% for the comparable period in 2009. This increase in gross margin resulted primarily from increased manufacturing capacity utilization as compared to the same period in 2009.





Research and Development Expenses.Research and development expenses as a percentage of net revenues represented 16.9% for the three months ended March 31, 2010 and 26.6% for the three months ended March 31, 2009. On a dollar basis, research and development expenses decreased $1.1 million or 9% to $11.4 million for the three months ended March 31, 2010 from $12.5 million for the comparable period in 2009. This decrease was primarily due to decreased prototype fabrication costs and decreased staffing costs. The Company believes that the development and introduction of new products is critical to its future success and expects to continue its investment in research and development activities in the future.





Selling, General and Administrative Expenses.As a percentage of net revenues, selling, general and administrative expenses represented 16.2% for the three months ended March 31, 2010 and 18.8% for the three months ended March 31, 2009. On a dollar basis, selling, general and administrative expenses increased $2.0 million, or 23%, to $10.9 million for the three months ended March 31, 2010 from $8.9 million for the comparable period in 2009. This increase was primarily due to increased commissions and increased profit sharing accruals.





Share-Based Compensation. The Company's results of operations for the three month periods ended March 31, 2010 and 2009 included $1.1 million and $708,000, respectively, of non-cash expense related to the fair value of share-based compensation awards. Share-based compensation expense is included in the statement of operations in cost of revenues, research and development expense and selling, general and administrative expense (see Note 3 of Notes to Condensed Consolidated Financial Statements).





Other Income (Expense). Other income, net reflects interest income from investments in short-term and long-term investment securities and money market funds and other non-operating income, offset by interest expense incurred on term notes.





Provision for Income Taxes.The income tax provision for the three months ended March 31, 2010, as a percentage of income before taxes, was 35.5%. The tax provision for this period excludes approximately 1.5% in benefits, as a percentage of income before taxes, from the Federal research and development credit which expired on December 31, 2009. The tax provision for the three months ended March 31, 2009, as a percentage of income before taxes, was 40.8%. The tax provision for this period included an additional $240,000 to reduce the amount of non-current deferred tax assets that were determined to be unrealizable due to California tax law changes in that period. The income tax provision for such interim periods differs from taxes computed at the federal statutory rate primarily due to the effect of non-deductible share-based compensation expense, state income taxes, federal and state research and development credits and federal qualified production activity deductions.

 MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (CONTINUED)





Liquidity and Capital Resources


Since inception, the Company's principal sources of funding have been its cash from operations, bank borrowings and sales of common stock. Principal sources of liquidity at March 31, 2010 consisted of cash and cash equivalents of $81.6 million and a $5 million revolving line of credit from a commercial bank.
 
 The Company generated $17.9 million in cash from operating activities for the three months ended March 31, 2010. Significant cash flows included cash provided by net income of $9.7 million plus additions for non-cash activities of $1.3 million (consisting primarily of $3.3 million in depreciation and amortization and $1.1 million in share-based compensation expense partially offset by a $3.1 million increase in deferred income taxes) combined with a $4.0 million decrease in income taxes receivable, a $5.2 million increase in deferred income, a $4.3 million increase in income taxes payable and a $1.7 million increase in accrued compensation, which were offset in part by a $6.6 million increase in accounts receivable combined with a $1.7 million decrease in accounts payable.
 
 For the three months ended March 31, 2009, the Company used $77,000 of cash in operating activities. Significant cash flows included cash provided by net income of $1.5 million plus additions for non-cash activities of $5.7 million (consisting primarily of $4.4 million in depreciation and amortization, $708,000 in share-based compensation expense and a $593,000 decrease in deferred tax provisions) combined with a $1.5 million decrease in inventories, which were offset by a $4.5 million decrease in other current liabilities, a $2.5 million decrease in deferred income on shipments to distributors and a $1.7 million decrease in accounts payable.
 
 The Company used $2.8 million of cash in investing activities during the three months ended March 31, 2010, comprised primarily of $1.7 million in net purchases of investments and $1.1 million of purchases of property, plant and equipment.
 
 For the three months ended March 31, 2009, the Company used $1.4 million of cash in investing activities, comprised of $1.2 million in purchases of property, plant and equipment and $131,000 in net purchases of investments.
 
 The Company used $4.5 million of cash in financing activities during the three months ended March 31, 2010 primarily for the $2.1 million for the payment of cash dividends, $2.1 million in repayments of long-term debt and the repurchase of $967,000 of the Company's common stock, which was partially offset by $798,000 in proceeds from employee stock transactions.
 
 For the three months ended March 31, 2009, the Company used $14.7 million of cash in financing activities primarily for the repurchase of $12.4 million of the Company's common stock and $2.3 million for the payment of cash dividends.
 
 The Company currently intends to spend approximately $10 million to $15 million to purchase capital equipment and make facility improvements during the next twelve months primarily for manufacturing equipment and additional research and development related software and equipment.
 
 On April 22, 2010, the Company's Board of Directors declared a $0.035 per common share cash dividend, payable May 26, 2010 to shareholders of record on May 12, 2010. The cash dividend payout by the Company on May 12, 2010 is expected to be approximately $2.2 million.
 
 The Company is currently authorized by its Board of Directors to repurchase an additional $14.0 million of its common stock through December 31, 2010.
 
 The Company believes that its cash from operations, existing cash balances and short-term investments, and its credit facility will be sufficient to meet its cash requirements for at least the next twelve months. In the longer term, the Company believes future cash requirements will continue to be met by its cash from operations, credit arrangements and future debt or equity financings as required.

Open purchase orders are defined as agreements to purchase goods or services that are enforceable and legally binding and that specify all significant terms, including: fixed or minimum quantities to be purchased; fixed, minimum or variable pricing provisions; and the approximate timing of the transactions.
 
 Borrowing agreements consisted of an unsecured credit facility with Bank of the West. The credit facility includes a $5 million line of credit available for general working capital needs, a $5 million letter of credit sub-facility and a $2 million foreign exchange sub-facility. As of March 31, 2010, the Company had no borrowings under the line of credit. The credit facility also includes a $15 million term loan facility to finance the repurchase of shares of the Company’s common stock. As of March 31, 2010, the Company had borrowed $15 million under the term loan facility, of which $5.7 million has been repaid.
 
 As of March 31, 2010, the Company had $6.9 million of non-current unrecognized tax benefits. Included in the $6.9 million is $2.0 million that has not yet reduced income tax payments, and, therefore, has been netted against non-current deferred tax assets. The remaining $4.9 million liability is included in long-term income taxes payable. The Company is not able to provide a reasonably reliable estimate of the timing of future payments relating to these obligations.





Off-Balance Sheet Arrangements





The Company has no other off-balance sheet arrangements and has not entered into any transactions involving unconsolidated, limited purpose entities or commodity contracts.

ITEM 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK





At March 31, 2010, the Company held $15.2 million in principal of senior auction rate notes secured by student loans. Auctions for these auction rate notes have failed as of March 31, 2010. The funds associated with failed auctions will not be accessible until a successful auction occurs, a buyer is found outside of the auction process, the issuers redeem the securities or the underlying securities have matured. As a result the Company’s ability to liquidate its investment and fully recover the carrying value of its investment in the near term may be limited or not exist. As of March 31, 2010, the Company has recorded a $2.7 million pre-tax temporary impairment of these securities to other comprehensive income, a component of shareholders’ equity. If it is determined that the fair value of these securities is other than temporarily impaired, the Company would record a loss, which could be material, in its statement of operations in the period such other than temporary decline in fair value is determined. The Company currently has the ability and intent to hold these investments until a recovery of the auction process occurs or the issuers redeem the securities.
 
 At March 31, 2010, the Company had no fixed-rate long-term debt subject to interest rate risk.
 
 At March 31, 2010, the Company held an interest rate swap contract, a derivative financial instrument, to partially offset its exposure to the effects of changes in interest rates on its variable-rate financing obligations. The notional amount of the outstanding interest rate swap contract at March 31, 2010 was $4.6 million. The Company currently intends to hold the interest rate swap contract to maturity. If market interest rates were to increase immediately and uniformly by 10 percent from levels at March 31, 2010, the fair value of the interest rate swap would decline by an immaterial amount.





ITEM 4:  CONTROLS AND PROCEDURES





The Company maintains disclosure controls and procedures, as such term is defined under Rule 13a-15(e) promulgated under the Securities Exchange Act of 1934, as amended (the Exchange Act). In designing and evaluating the disclosure controls and procedures, management recognizes that any disclosure controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management necessarily is required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.
 
 Under the supervision and with the participation of the Company's management, including its principal executive officer and principal financial officer, the Company conducted an evaluation of the effectiveness of its disclosure controls and procedures as of the end of the period covered by this report. Based on this evaluation, the Company's principal executive officer and principal financial officer have concluded that the Company's disclosure controls and procedures were effective at the reasonable assurance level as of March 31, 2010.
 
 There has been no change in the Company’s internal control over financial reporting during the Company’s most recent fiscal quarter that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.

PART II.  OTHER INFORMATION





ITEM 1.  LEGAL PROCEEDINGS





The information included in Note 14 of Notes to Condensed Consolidated Financial Statements under the caption "Litigation and Other Contingencies" in Item 1 of Part I is incorporated herein by reference.





ITEM 1A.  RISK FACTORS





Factors That May Affect Operating Results





If a company's operating results are below the expectations of public market analysts or investors, then the market price of its Common Stock could decline. Many factors that can affect a company's quarterly and annual results are difficult to control or predict. Some of the factors which can affect a multinational semiconductor business such as the Company are described below.


Geopolitical and Macroeconomic Risks That May Affect Multinational Enterprises





Weak global economic conditions could have a material adverse effect on the Company’s business, results of operations, and financial condition.While the current global economic downturn may be improving and the Company has recently seen improvement in the business climate for semiconductors, there is no guarantee that these conditions will continue to improve or that these conditions will not further decline again in the future. The semiconductor industry has traditionally been highly cyclical and has often experienced significant downturns in connection with, or in anticipation of, declines in general economic conditions. The Company cannot accurately predict the timing, severity or duration of such downturns. A continuation of the global recession and credit crisis in the financial markets may result in a decrease in orders for the Company’s products, which may materially adversely affect the Company’s revenues, results of operations and financial condition. In addition to reduction in sales, the Company’s profitability may decrease during economic downturns because the Company may not be able to reduce costs at the same rate as its sales decline.
 
 Demand for semiconductor components is increasingly dependent upon the rate of growth of the global economy.Many factors could adversely affect regional or global economic growth. Some of the factors that could slow global economic growth include: continued volatility in the United States and global credit markets, increased price inflation for goods, services or materials, a slowdown in the rate of growth of the Chinese economy, a significant act of terrorism which disrupts global trade or consumer confidence, and geopolitical tensions including war and civil unrest. Reduced levels of economic activity, or disruptions of international transportation, could adversely affect sales on either a global basis or in specific geographic regions.
 
 Market conditions may lead the Company to initiate cost reduction plans, which may negatively affect near term operating results.Weaker customer demand, competitive pricing pressures, excess capacity, weak economic conditions or other factors, may cause the Company to initiate actions to reduce the Company’s cost structure and improve the Company’s future operating results. The cost reduction actions may require incremental costs to implement, which could negatively affect the Company’s operating results in periods when the incremental costs or liabilities are incurred.

 Table of Contents





Tightening of the credit markets may adversely affect the Company’s business in a number of ways.The unprecedented contraction and extreme disruption of the credit and financial markets in the United States, Europe, and Asia led to, among other things, extreme volatility in security prices, severely diminished liquidity and credit availability, rating downgrades of certain investments and declining valuation of others. These economic developments adversely affected the Company’s business in a number of ways. A similar tightening of credit in financial markets may limit the ability of the Company’s customers and suppliers to obtain financing for capital purchases and operations. This could result in a decrease in or cancellation of orders for the Company’s products or reduced ability to finance operations to supply products to the Company. The Company cannot predict the likely duration and severity of disruptions in financial markets and adverse economic conditions in the U.S. and other countries. Further, fluctuations in worldwide economic conditions make it is extremely difficult for the Company to forecast future sales levels based on historical information and trends. Visibility into customer demand continues to be limited due to short order lead times. Portions of the Company’s expenses are fixed and other expenses are tied to expected levels of sales activities. To the extent the Company does not achieve its anticipated levels of sales, its gross profit and net income could be adversely affected until such expenses are reduced to an appropriate level.





The Company has generated a substantial portion of its net revenues from export sales.The Company believes that a substantial portion of its future net revenues will depend on export sales to customers in international markets, including Asia. International markets are subject to a variety of risks, including changes in policy by the U.S. or foreign governments, acts of terrorism, foreign government instability, social conditions such as civil unrest, economic conditions including high levels of inflation, fluctuation in the value of foreign currencies and currency exchange rates and trade restrictions or prohibitions. Changes in exchange rates that strengthen the U.S. dollar could increase the price of the Company's products in the local currencies of the foreign markets it serves. This would result in making the Company's products relatively more expensive than its competitors' products that are denominated in local currencies, leading to a reduction in sales or profitability in those foreign markets. The Company has not taken any protective measures against exchange rate fluctuations, such as purchasing hedging instruments. In addition, the Company sells to domestic customers that do business worldwide and cannot predict how the businesses of these customers may be affected by economic or political conditions elsewhere in the world. Such factors could adversely affect the Company's future revenues, financial condition, results of operations or cash flows.








Semiconductor Industry Specific Risks





The volatility of customer demand in the semiconductor industry limits a company's ability to predict future levels of sales and profitability. Semiconductor suppliers can rapidly increase production output, leading to a sudden oversupply situation and a subsequent reduction in order rates and revenues as customers adjust their inventories to true demand rates. A rapid and sudden decline in customer demand for products can result in excess quantities of certain products relative to demand. Should this occur the Company’s operating results may be adversely affected as a result of charges to reduce the carrying value of the Company’s inventory to the estimated demand level or market price. The Company's quarterly revenues are highly dependent upon turns fill orders (orders booked and shipped in the same quarter). The short-term and volatile nature of customer demand makes it extremely difficult to accurately predict near term revenues and profits.





The semiconductor industry is highly competitive and subject to rapid technological change, price-erosion and increased international competition.Significant competitive factors include product features; performance and price; timing of product introductions; emergence of new computer and communications standards; and quality and customer support. If the Company is unable to compete favorably in these areas, revenues and profits could be negatively affected.





The short lead time environment in the semiconductor industry has allowed many end consumers to rely on semiconductor suppliers, stocking representatives and distributors to carry inventory to meet short term requirements and minimize their investment in on-hand inventory.Over the past several years, customers have worked to minimize the amount of inventory of semiconductors they hold. As a consequence, customers are generally providing less order backlog to the Company and other semiconductor suppliers, resulting in short order lead times and reduced visibility into customer demand. As a consequence of the short lead time environment and corresponding unpredictability of customer demand, the Company has increased its inventories over the past five to six years to maintain reliable service levels. If actual customer demand for the Company’s products is different from the Company’s estimated demand, product inventory may have to be scrapped, or the carrying value reduced, which could adversely affect the Company's business, financial condition, results of operations, or cash flows.


26
 Table of Contents


In addition, the Company maintains a network of stocking representatives and distributors that carry inventory to service the volatile short-term demand of the end customer. Should the relationship with a distributor or stocking representative be terminated, the future level of product returns could be higher than the returns allowance established, which could negatively affect the Company’s revenues and results of operations.


During periods when economic growth and customer demand have been less certain, both the semiconductor industry and the Company have experienced significant price erosion.If price erosion occurs, it will have the effect of reducing revenue levels and gross margins in future periods. Furthermore, the trend for the Company’s customers to move their electronics manufacturing to Asian countries has brought increased pricing pressure for Micrel and the semiconductor industry as a whole. Asian based manufacturers are typically more concerned about cost and less concerned about the capability of the integrated circuits they purchase. The increased concentration of electronics procurement and manufacturing in the Asia Pacific region may lead to continued price pressure and additional product advertising costs for the Company’s products in the future.
 
 Many semiconductor companies, including the Company, face risks associated with a dependence upon third parties that manufacture, assemble or package certain of its products.These risks include reduced control over delivery schedules and quality; inadequate manufacturing yields and excessive costs; the potential lack of adequate capacity during periods of excess demand; difficulties selecting and integrating new subcontractors; potential increases in prices; disruption in supply due to civil unrest, terrorism, natural disasters or other events which may occur in the countries in which the subcontractors operate; and potential misappropriation of the Company's intellectual property. The occurrence of any of these events may lead to increased costs or delay delivery of the Company's products, which would harm its profitability and customer relationships. The Company does not have long-term supply contracts with any of its third-party vendors. Therefore, the vendors are not obligated to perform services or supply products to the Company for any specific period, in any specific quantities, or at any specific price, except as may be provided in a particular accepted purchase order or guarantee. Additionally, the Company's wafer and product requirements typically represent a relatively small portion of the total production of the third-party foundries and outside assembly, testing and packaging contractors. As a result, Micrel is subject to the risk that a third-party supplier will provide delivery or capacity priority to other larger customers at the expense of Micrel, resulting in an inadequate supply to meet customer demand or higher costs to obtain the necessary product supply.
 
 The Company outsources some of its wafer fabrication, most of its test and all of its assembly requirements to third-party vendors. With recent improving demand for semiconductors, availability of these outsourced services is getting tight, resulting in longer than normal lead times and delinquent shipments to customers. The degree to which Micrel may have difficulty obtaining these services could have a negative impact on the Company’s revenues, bookings and backlog. The Company is seeing these lead times move from the traditional four to six week range to the five to seven week range. If these lead times extend beyond eight weeks, the resulting loss of near-term visibility for our customers could result in their placing higher order levels than their actual requirements which may result in higher levels of order cancellations in the future. There can be no assurance that the Company will be able to accurately forecast demand and moderate its build schedules to accommodate the possibility of an increase in order cancellations. Accordingly, the Company faces the risk of overbuilding inventory which is a typical consequence of sharp demand increases such as those we are currently experiencing.
 
 The markets that the Company serves frequently undergo transitions in which products rapidly incorporate new features and performance standards on an industry-wide basis.If the Company's products are unable to support the new features or performance levels required by OEMs in these markets, it would likely lose business from existing or potential customers and would not have the opportunity to compete for new design wins until the next product transition. If the Company fails to develop products with required features or performance standards or experiences even a short delay in bringing a new product to market, or if its customers fail to achieve market acceptance of their products, its revenues could be significantly reduced for a substantial period of time.

Because the standard products market for ICs is diverse and highly fragmented, the Company encounters different competitors in various market areas.Many of these competitors have substantially greater technical, financial and marketing resources and greater name recognition than the Company. The Company may not be able to compete successfully in either the standard products or custom and foundry products business in the future and competitive pressures may adversely affect the Company's financial condition, results of operations, or cash flows.
 
 The success of companies in the semiconductor industry depends in part upon intellectual property, including patents, trade secrets, know-how and continuing technology innovation. The success of companies like Micrel may depend on their ability to obtain necessary intellectual property rights and protect such rights. There can be no assurance that the steps taken by the Company to protect its intellectual property will be adequate to prevent misappropriation or that others will not develop competitive technologies or products. There can be no assurance that any patent owned by the Company will not be invalidated, circumvented or challenged, that the rights granted thereunder will provide competitive advantages or that any of its pending or future patent applications will be issued with the scope of the claims sought, if at all. Furthermore, others may develop technologies that are similar or superior to the Company's technology, duplicate technology or design around the patents owned by the Company. Additionally, the semiconductor industry is characterized by frequent litigation regarding patent and other intellectual property rights. Claims alleging infringement of intellectual property rights have been asserted against the Company in the past and could be asserted against the Company in the future. These claims could result in the Company having to discontinue the use of certain processes; cease the manufacture, use and sale of infringing products; incur significant litigation costs and damages; attempt to obtain a license to the relevant intellectual property and develop non-infringing technology. The Company may not be able to obtain or renew such licenses on acceptable terms or to develop non-infringing technology. Existing claims or other assertions or claims for indemnity resulting from infringement claims could adversely affect the Company's business, financial condition, results of operations, or cash flows. In addition, the Company relies on third parties for certain technology that is integrated into some of its products. If the Company is unable to continue to use or license third-party technologies in its products on acceptable terms, or the technology fails to operate, the Company may not be able to secure alternative technologies in a timely manner and its business would be harmed.
 
 The significant investment in semiconductor manufacturing capacity and the rapid growth of circuit design centers in China may present a competitive threat to established semiconductor companies due to the current low cost of labor and capital in China.The emergence of low cost competitors in China could reduce the revenues and profitability of established semiconductor manufacturers.
 
 There is intense competition for qualified personnel in the semiconductor industry. The loss of any key employees or the inability to attract or retain qualified personnel, including management, engineers and sales and marketing personnel, could delay the development and introduction of the Company’s products, and harm its ability to sell its products. The Company believes that its future success is dependent on the contributions of its senior management, including its President and Chief Executive Officer, certain other executive officers and senior engineering personnel. The Company does not have long-term employment contracts with these or any other key personnel, and their knowledge of the Company’s business and industry would be difficult to replace.
 
 Companies in the semiconductor industry are subject to a variety of federal, state and local governmental regulations related to the use, storage, discharge and disposal of toxic, volatile or otherwise hazardous chemicals used in its manufacturing process.Any failure to comply with present or future regulations could result in the imposition of fines, the suspension of production, alteration of manufacturing processes or a cessation of operations. In addition, these regulations could restrict the Company's ability to expand its facilities at their present locations or construct or operate a new wafer fabrication facility or could require the Company to acquire costly equipment or incur other significant expenses to comply with environmental regulations or clean up prior discharges. The Company's failure to appropriately control the use of, disposal or storage of, or adequately restrict the discharge of, hazardous substances could subject it to future liabilities and could have a material adverse effect on its business.

Company-Specific Risks





In addition to the risks that affect multinational semiconductor companies listed above, there are additional risks which are more specific to the Company such as:





An important part of the Company's strategy is to continue to focus on the market for high-speed communications ICs.Should demand from the Company’s customers in this end market decrease, or if lower customer demand for the Company’s high bandwidth products materializes, the Company's future revenue growth and profitability could be adversely affected.





The cellular telephone (wireless handset) market comprises a significant portion of the Company’s standard product revenues.The Company derives a significant portion of its net revenues from customers serving the cellular telephone market. Due to the highly competitive and fast changing environment in which the Company’s cellular telephone customers operate, demand for the product the Company sells into this end market can change rapidly and unexpectedly. If the Company’s cellular telephone customers acceptance of Micrel’s products decreases, or if these customers lose market share, or accumulate too much inventory of completed handsets, the demand for the Company’s products could decline sharply which could adversely affect the Company’s revenues and results of operations.





The Company’s gross margin, operating margin and net income are highly dependent on the level of revenue and capacity utilization that the Company experiences.Semiconductor manufacturing is a capital-intensive business resulting in high fixed costs. If the Company is unable to utilize its installed wafer fabrication or test capacity at a high level, the costs associated with these facilities and equipment would not be fully absorbed, resulting in higher average unit costs and lower profit margins.





The Company has invested in certain auction rate securities that may not be accessible for in excess of 12 months and these auction rate securities may experience an other than temporary decline in value, which would adversely affect the Company’s income.At March 31, 2010, the Company held $15.2 million in principal of auction rate notes secured by student loans. As of March 31, 2010, all of these auction rate securities have failed to auction successfully due to sell orders exceeding buy orders. The Company has recorded a $2.7 million pre-tax temporary impairment of these securities to other comprehensive income, a component of shareholders’ equity. If it is determined that the fair value of these securities is other than temporarily impaired, the Company would record a loss, which could be material, in its statement of operations in the period such other than temporary decline in fair value is determined.

The Company faces various risks associated with the trend toward increased shareholder activism.In 2008, the Company became engaged in a proxy contest with a large shareholder. This dispute led to a significant increase in operating expenses which appreciably reduced the Company’s operating profit and net income. The Company prevailed in the contest and has subsequently repurchased 4,675,000 shares of the Company’s Common Stock from the activist shareholder and entered into a standstill agreement with the shareholder restricting their actions as a shareholder of the Company. While this dispute has been resolved, the Company could become engaged in another proxy contest in the future. Another proxy contest would require significant additional management time and increased operating expenses, which could adversely affect the Company’s profitability and cash flows.





The semiconductor industry is characterized by frequent litigation regarding patent and other intellectual property rights.To the extent that the Company becomes involved in such intellectual property litigation, it could result in substantial costs and diversion of resources to the Company and could have a material adverse effect on the Company's financial condition, results of operation or cash flows.

In the event of an adverse ruling in any intellectual property litigation that might arise in the future, the Company might be required to discontinue the use of certain processes, cease the manufacture, use and sale of infringing products, expend significant resources to develop non-infringing technology or obtain licenses to the infringing technology. There can be no assurance, however, that under such circumstances, a license would be available under reasonable terms or at all. In the event of a successful claim against the Company and the Company's failure to develop or license substitute technology on commercially reasonable terms, the Company's financial condition, results of operations, or cash flows could be adversely affected. The Company does not believe that any material and specific risk currently exists related to the loss of use of patents, products or processes.





The complexity of the Company’s products may lead to errors or defects, which could subject the Company to significant costs or damages and adversely affect market acceptance of its products. Although the Company’s customers and suppliers rigorously test its products, these products may contain undetected errors, weaknesses or defects. If any of the Company’s products contain production defects, reliability, quality or compatibility problems that are significant, the Company’s reputation may be damaged and customers may be reluctant to continue to buy its products. This could adversely affect the Company’s ability to retain and attract new customers. In addition, these defects could interrupt or delay sales of affected products, which could adversely affect the Company’s results of operations.





If defects are discovered after commencement of commercial production, the Company may be required to incur significant costs to resolve the problems. This could result in significant additional development costs and the diversion of technical and other resources from other development efforts. The Company could also incur significant costs to repair or replace defective products or may agree to be liable for certain damages incurred. These costs or damages could have a material adverse effect on the Company’s financial condition and results of operations.





The Company will continue to expend substantial resources developing new products, applications or markets and may never achieve the sales volume that it anticipates for these products, which may limit the Company’s future growth and harm its results of operations.The Company’s future success will depend in part upon the success of new products. The Company has in the past, and will likely in the future, expend substantial resources in developing new and additional products for new applications and markets. The Company may experience unforeseen difficulties and delays in developing these products and experience defects upon volume production and broad deployment. The markets the Company enters will likely be highly competitive and competitors may have substantially more experience in these markets. The Company’s success will depend on the growth of the markets it enters, the competitiveness of its products and its ability to increase market share in these markets. If the Company enters markets that do not achieve or sustain the growth it anticipates, or if the Company’s products are not competitive, it may not achieve volume sales, which may limit the Company’s future growth and would harm its results of operations.





If the Company is unable to convert a significant portion of its design wins into revenue, the Company’s business, financial condition and results of operations could be materially and adversely impacted.The Company has secured a significant number of design wins for new and existing products. Such design wins are necessary for revenue growth. However, many of the Company’s design wins may never generate revenues if end-customer projects are unsuccessful in the marketplace or the end-customer terminates the project, which may occur for a variety of reasons. Mergers and consolidations among customers may lead to termination of certain projects before the associated design win generates revenue. If design wins do generate revenue, the time lag between the design win and meaningful revenue is typically from six months to greater than eighteen months. If the Company fails to convert a significant portion of its design wins into substantial revenue, the Company’s business, financial condition and results of operations could be materially and adversely impacted.

If the Company’s distributors or sales representatives stop selling or fail to successfully promote its products, the Company’s business, financial condition and results of operations could be adversely impacted.Micrel sells many of its products through sales representatives and distributors. The Company’s non-exclusive distributors and sales representatives may carry its competitors’ products, which could adversely impact or limit sales of the Company’s products. Additionally, they could reduce or discontinue sales of the Company’s products or may not devote the resources necessary to adequately sell the Company’s products. The Company’s agreements with distributors contain limited provisions for return of products, including stock rotations whereby distributors may return a percentage of their purchases based upon a percentage of their most recent three months of shipments. In addition, in certain circumstances upon termination of the distributor relationship, distributors may return some portion of their prior purchases. The loss of business from any of the Company’s significant distributors or the delay of significant orders from any of them, could materially and adversely harm the Company’s business, financial conditions and results of operations.




In addition, the Company depends on the continued viability and financial resources of these distributors and sales representatives, some of which are small organizations with limited working capital. In turn, these distributors and sales representatives are subject to general economic and semiconductor industry conditions. If some or all of the Company’s distributors and sales representatives experience financial difficulties, or otherwise become unable or unwilling to promote and sell the Company’s products, its business, financial condition and results of operations could be adversely impacted.





The Company manufactures most of its semiconductors at its San Jose, California fabrication facilities. The Company's existing wafer fabrication facility, located in Northern California, may be subject to natural disasters such as earthquakes. A significant natural disaster, such as an earthquake or prolonged drought, could have a material adverse impact on the Company's business, financial condition and operating results. Furthermore, manufacturing semiconductors requires manufacturing tools that are unique to each product being produced. If one of these unique manufacturing tools was damaged or destroyed, the Company's ability to manufacture the related product would be impaired and its business would suffer until the tool was repaired or replaced. Additionally, the fabrication of ICs is a highly complex and precise process. Small impurities, contaminants in the manufacturing environment, difficulties in the fabrication process, defects in the masks used to print circuits on a wafer, manufacturing equipment failures, and wafer breakage or other factors can cause a substantial percentage of wafers to be rejected or numerous die on each wafer to be nonfunctional. The Company maintains approximately two to three months of inventory that has completed the wafer fabrication manufacturing process. This inventory is generally located offshore at third party subcontractors and can act to buffer some of the adverse impact from a disruption to the Company’s San Jose wafer fabrication activity arising from a natural disaster such as an earthquake.





The Company’s results of operations could vary as a result of the methods, estimations and judgments used in applying its accounting policies.The methods, estimates and judgments used by the Company in applying its accounting policies have a significant impact on its results of operations. Such methods, estimates and judgments are, by their nature, subject to substantial risks, uncertainties, assumptions and changes in rulemaking by the regulatory bodies, and factors may arise over time that lead the Company to change its methods, estimates, and judgments. Changes in those methods, estimates and judgments could significantly impact the Company’s results of operations.





Changes in tax laws could adversely affect the Company’s results of operations. The Company is subject to income taxes in the United States and in various immaterial foreign jurisdictions. Significant judgment is required in determining the Company’s worldwide tax liabilities. The Company believes that it complies with applicable tax law. If the governing tax authorities have a different interpretation of the applicable law or if there is a change in tax law, the Company’s financial condition and results of operations may be adversely affected.





In addition, there have been proposals to reform U.S. tax laws that could significantly impact how U.S. multinational corporations are taxed on foreign earnings. Although the Company cannot predict whether or in what form this proposed legislation will pass, if enacted it could have a material impact on our results of operations. It should be noted the Company does not currently have a material foreign tax structure and the majority of the Company’s income is subject to U.S. corporate tax laws.
