Industry Background

Analog Circuit, Mixed-Signal and Digital ICs Markets

ICs may be divided into three general categories — digital, analog (also known as ''linear'') and mixed-signal. Digital circuits, such as memories and microprocessors, process information in the form of on-off electronic signals and are capable of implementing only two values, "1" or "0." Analog circuits, such as regulators, converters and amplifiers, process information in the form of continuously varying voltages and currents that have an infinite number of values or states. Analog circuits condition, process, and measure or control real world variables such as current, sound, temperature, pressure or speed. Mixed-signal ICs combine analog and digital functions on one chip.

Analog circuits are used in virtually every electronic system, and the largest markets for such circuits are computers, telecommunications and data communications, industrial equipment, military, consumer and automotive electronics. Because of their numerous applications, analog circuits have a wide range of operating specifications and functions. For each application, different users may have unique requirements for circuits with specific resolution, linearity, speed, power and signal amplitude capability.

Mixed-signal and digital ICs may be divided into six general categories, LSI/MSI logic, data processing, signal processing, memory, FPGA and application specific.

Mixed-signal and digital ICs are used in computer and communication systems and in industrial products. The primary markets for such circuits are consumer, communications, personal and enterprise computer systems, networking and industrial.

As compared with the digital integrated circuit industry, the analog integrated circuit industry has the following important characteristics:

· Dependence on Individual Design Teams. The design of analog circuits involves the complex and critical placement of various circuits. Analog circuit design has traditionally been highly dependent on the skills and experience of individual design engineers.

· Interdependence of Design and Process. Analog designers, especially at companies having their own wafer fabrication facility, are able to select from several wafer fabrication processes in order to achieve higher performance and greater functionality from their designs.

· Longer Product Cycles and More Stable Pricing. Analog circuits generally have longer product cycles and greater price stability as compared to digital circuits.

Analog, mixed-signal and digital ICs are sold to customers as either standard products or custom products.

Recent Trends in Analog Power Management, Mixed-Signal and Digital ICs

Most electronic systems utilize analog circuits to perform power management functions (''power analog circuits'') such as the control, regulation, conversion and routing of voltages and current. The computer and communications markets have emerged as two of the largest markets for power analog circuits. In particular, the recent growth and proliferation of portable, battery-powered devices, such as cellular telephones, digital cameras, portable media players and notebook computers, continue to increase demand and create new technological challenges for power analog circuits.

5

Cellular telephones, which are composed of components and subsystems that utilize several different voltage levels, require multiple power analog circuits to precisely regulate and control voltage. Manufacturers continue to pack more processing power and functionality into smaller form factors placing severe demands on the battery. To maintain or extend talk times, high performance power management products are required.

The rapid adoption of the Internet for information exchange, in business and consumer markets, has led to a significant increase in the need for broadband communications technology. In recent years, there has been a significant expansion in the number of broadband subscribers for both DSL, cable modem and fiber to the home technologies. The increased bandwidth demand of these users will continue to consume the installed capacity in metropolitan and wide area networks. The additional demand of new wireless services utilizing the transmission of video will further consume this installed capacity.

In the networking market, Ethernet has been widely adopted as a communication standard. Ethernet ports are now being provided on equipment ranging from PCs and PC peripherals to other consumer products such as printers, Internet Protocol Set-Top Boxes ("IP-STB"), Internet Protocol Phones ("IP-phone"), game consoles, media converters and industrial equipment. This is driving rapid growth in both the digital home market to connect multiple PCs and peripherals and the industrial market to connect machinery to central control and monitoring equipment.

Sales, Distribution and Marketing

The Company sells its products through a worldwide network of independent sales representative, independent distributor and stocking representative firms and through a direct sales staff.

9

The Company sells its products in Europe through a direct sales staff in England, France, Germany, Finland and Sweden as well as independent sales representative firms, independent distributors and independent stocking representative firms. Asian sales are handled through Micrel sales offices in Korea, Japan, Taiwan, China and Singapore, independent distributors and independent stocking representative firms. The 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.

In 2007, sales to customers in North America, Asia and Europe accounted for 33%, 55% and 12% respectively, of the Company's net revenues. 2007 sales in North America, Asia and Europe, as a percentage of net revenues, was about the same as 2006 which was 30%, 59% and 11%, respectively. As compared to 2005, 2007 sales to North America as a percentage of net revenues was up 8%, Asia was down 10% and Europe was up 2%. 2005 sales to customers in North America, Asia and Europe accounted for 25%, 65% and 10%, respectively, of net revenues. The Company's standard products are sold throughout the world, while its custom and foundry products are primarily sold to North American customers. The Company's net revenues by country, including the United States, are included in Note 11 of Notes to Consolidated Financial Statements.

The Company's international sales are primarily denominated in U.S. dollars. Consequently, changes in exchange rates that strengthen the U.S. dollar could increase the price in local currencies of the Company's products in foreign markets and make the Company's products relatively more expensive than 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 with respect to such fluctuations.

Customers

For the year ended December 31, 2007 two worldwide distributors accounted for 15% and 13%, respectively, of the Company's net revenues. For the year ended December 31, 2006 three customers, two worldwide distributors and an Asian based stocking representative accounted for 13%, 12% and 10%, respectively, of the Company's net revenues. For the year ended December 31, 2005 three customers, an Asian based original equipment manufacturer, an Asian based stocking representative and a worldwide distributor, accounted for 14%, 12% and 12%, respectively, of the Company's net revenues.

Design and Process Technology

Micrel's analog proprietary design technology depends on the skills of its analog design team. The Company has experienced analog design engineers who utilize an extensive macro library of analog and mixed-signal circuits and computer simulation models.

Micrel can produce ICs using a variety of manufacturing processes, some of which are proprietary and provide enhanced product features. Designers at companies that do not have in-house fabs or have a limited selection of available processes often have to compromise design methodology in order to match process parameters.

10

The Company utilizes the following process technologies:

· Bipolar

· High Speed Bipolar

· Superβeta PNP™

· CMOS

· BiCMOS — Bipolar/CMOS (''BiCMOS'')

· BCD — Bipolar/CMOS/DMOS (''BCD'')

· ASSET — All Spacer Separated Element Transistor ("ASSET")

· Silicon Germanium – Silicon Germanium (“SiGe”)

The Company continues to develop process technologies to improve both the performance and cost of its new products. Micrel is also developing new process technologies to support its own product development and the needs of its foundry customers.

The Company utilizes third-party wafer fabrication foundries for advanced CMOS fabrication processes and other advanced processes that are not available in-house. For the year ended December 31, 2007, approximately 5% of Micrel's wafer requirements were fabricated at third-party foundry suppliers, including all of Micrel's Ethernet networking products.

Research and Development

The ability of the Company to compete will substantially depend on its ability to define, design, develop and introduce on a timely basis new products offering design or technology innovations. Research and development in the analog and mixed-signal integrated circuit industry is characterized primarily by circuit design and product engineering that enables new functionality or improved performance. The Company's research and development efforts are also directed at its process technologies and focus on cost reductions to existing manufacturing processes and the development of new process capabilities to manufacture new products and add new features to existing products. With respect to more established products, the Company's research and development efforts also include product redesign, shrinkage of device size and the reduction of mask steps in order to improve die yields per wafer and reduce per device costs.

The Company's analog design engineers principally focus on developing next generation standard products. The Company's new product development strategy emphasizes a broad line of standard products that are based on customer input and requests.

The Company's mixed-signal design engineers principally focus on high-speed, low-noise media driving and clock/data recovery devices used in communication and advanced computer systems.

In 2007, 2006, and 2005 the Company spent $54.5 million $52.1 million, and $45.2 million, respectively, on research and development. The Company expects that it will continue to spend substantial funds on research and development activities.

Patents and Intellectual Property Protection

The Company seeks patent protection for those inventions and technologies for which such protection is suitable and is likely to provide a competitive advantage to the Company.  The Company currently holds 225 United States patents on semiconductor devices and methods, with various expiration dates through 2026.  The Company has applications for 102 United States patents pending.  The Company holds 46 issued foreign patents and has applications for 69 foreign patents pending.

Supply of Materials and Purchased Components

Micrel currently purchases certain components from a limited group of vendors. The packaging of the Company's products is performed by, and certain of the raw materials included in such products are obtained from, a limited group of suppliers. The wafer supply for the Company’s Ethernet products is primarily dependent upon two large third-party wafer foundry suppliers.

Manufacturing

 The Company produces the majority of its wafers at the Company’s wafer fabrication facility located in San Jose, California while a small percentage of wafer fabrication is subcontracted to outside foundries, including 100% of Micrel's Ethernet product wafer requirements. The San Jose facility includes a 57,000 square foot office and manufacturing facility containing a 28,000 square foot clean room facility, which provides production processes. Approximately 70% of the San Jose facility's clean room space is classified as a Class 1 facility, which means that the facility achieves a clean room level of fewer than 1 foreign particle larger than 0.3 microns in size in each cubic foot of space. The remainder of the facility's clean room space is classified as Class 10, achieving fewer than 10 foreign particles larger than 0.3 microns in size in each cubic foot of space. The facility uses six-inch wafer technology. The Company also owns approximately 63,000 square feet of additional adjacent space in San Jose that is used as a testing facility and administrative offices.

Generally, each die on the Company's wafers is electrically tested for performance, and most of the wafers are subsequently sent to independent assembly and final test contract facilities in Malaysia and certain other Asian countries. At such facilities, the wafers are separated into individual circuits and packaged. The Company's reliance on independent assemblers may subject the Company to longer manufacturing cycle times. The Company from time to time has experienced competition with respect to these contractors from other manufacturers seeking assembly of circuits by independent contractors.

Competition

The semiconductor industry is highly competitive and subject to rapid technological change. Significant competitive factors in the market for standard products include product features, performance, price, the timing of product introductions, the emergence of new technological standards, quality and customer support. The Company believes that it competes favorably in all of these areas.

12

Because the standard products market for analog ICs is diverse and highly fragmented, the Company encounters different competitors in its various market areas. The Company's principal analog circuit competitors include Linear Technology Corporation, Maxim Integrated Products, Inc., and National Semiconductor Corp. in one or more of its product areas. Other competitors include Texas Instruments, Freescale Semiconductor (formerly Motorola), Intersil, Fairchild Semiconductor, Advanced Analogictech, Semtech and ON Semiconductor. Each of these companies has substantially greater technical, financial and marketing resources and greater name recognition than the Company. The Company's principal competitors for products targeted at the high bandwidth communications market are ON Semiconductor, Analog Devices, Maxim Integrated Products, Inc., Vitesse Semiconductor Corp., Integrated Device Technology and Mindspeed. The primary competitors for Micrel's Ethernet products are Broadcom Corp., Marvell Technology Group Ltd. and a number of Taiwanese companies.

With respect to the custom and foundry products business, significant competitive factors include product quality and reliability, established relationships between customers and suppliers, timely delivery of products, and price. The Company believes that it competes favorably in all these areas.

Backlog

At December 31, 2007, the Company's backlog was approximately $48 million, all of which is scheduled to be shipped during the first six months of 2008. December 31, 2007 backlog was up 12% from the December 31, 2006 backlog of approximately $43 million. Orders in backlog are subject to cancellation or rescheduling by the customer, generally with a cancellation charge in the case of custom and foundry products. The Company's backlog consists of distributor and customer released orders requesting shipment within the next six months. Shipments to United States, Canadian and certain other international distributors who receive significant return rights and price adjustments from the Company are not recognized as revenue by the Company until the product is sold from the distributor stock and through to the end-users. Because of possible changes in product delivery schedules and cancellation of product orders and because an increasing percentage of the Company's sales are shipped in the same quarter that the orders are received, the Company's backlog at any particular date is not necessarily indicative of actual sales for any succeeding period.

Environmental Matters

Federal, state and local regulations impose various environmental controls on the storage, handling, discharge and disposal of chemicals and gases used in the Company's manufacturing process. The Company believes that its activities conform to present environmental regulations.

Employees

As of December 31, 2007, the Company had 923 full-time employees as compared to 932 at December 31, 2006. The Company's employees are not represented by any collective bargaining agreements, and the Company has never experienced a work stoppage. The Company believes that its employee relations are good.

Segment Information

The Company has two reportable segments: standard products and other product revenues, which consist primarily of custom and foundry products revenues and revenues from the license of patents. Segment financial information is presented in Note 11 in the Consolidated Financial Statements, which is incorporated by reference here.

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

Demand for semiconductor components is increasingly dependent upon the rate of growth of the global economy.   If the rate of global economic growth slows, or contracts, customer demand for products could be adversely affected, which in turn could negatively affect revenues, results of operations and financial condition.  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 additional 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 additional 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.

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.

14

The Company is reliant on certain key suppliers for wafer fabrication, circuit assembly and testing services. Most of these suppliers are based outside of the U.S. The Company's supply could be interrupted as a result of any of the previously mentioned risk factors relating to international markets.

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; 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.  Original equipment manufacturers, distributors and contract manufacturers within the electronics industry have reduced their semiconductor component days of inventory on hand by approximately 20% over the past six years. Over the same six years, the industry average for semiconductor manufacturers inventory days on hand has increased by approximately 25%. 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 approximately 20% 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. 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.

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.

15

Many semiconductor companies 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 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.  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 foundry 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.

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.  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.

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, or the failure to obtain a key license or renew or renegotiate existing licenses on favorable terms could adversely affect the Company's business, financial condition, results of operations, or cash flows.

16

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, in particular design engineers.  The Company may not be able to continue to attract and train engineers or other qualified personnel necessary for the development of its business or to replace engineers or other qualified personnel who may leave its employ in the future. Loss of the services of, or failure to recruit, key design engineers or other technical and management personnel could be significantly detrimental to the Company's product and process development programs.

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.

The Statement of Financial Accounting Standards No.123R, "Share-Based Payment” requires the Company to recognize the cost of employee services received in exchange for awards of equity instruments, based on the grant date fair value of those awards, in the financial statements.  As discussed in Note 6 of the Notes to Consolidated Financial Statements, the effect of the adoption of this accounting standard in 2006 has significantly increased stock based compensation expense in the current period and such expense is expected to continue in future periods.  The requirement to recognize the cost of stock option awards as an expense in the financial statements has and will continue to reduce net income and earnings per share and may have an adverse affect on the value of the Company’s common stock.  If the Company reduces the number of stock option grants to employees to minimize the cost associated with share based incentive awards, it will most likely be more difficult for the Company to hire and retain employees.

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:

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.

The Company's long-term investments of $16.6 million at December 31, 2007, consist of senior auction rate notes secured by student loans. In February 2008, some of these auction rate securities failed to auction successfully due to sell orders exceeding buy orders (see discussion of investments in Note 1 of Notes to Consolidated Financial Statements).

17

The Company is evaluating the impact of these failed auctions on the fair value of these securities. If the Company determines that the fair value of these auction rate securities is temporarily impaired, the Company would record a temporary impairment within other comprehensive loss, a component of shareholders' equity, in the period such temporary decline in fair value is determined.  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’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 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 can decline sharply which could adversely affect the Company’s revenues and results of operations.

An important part of the Company's strategy is to continue to focus on the market for high-speed communications IC’s.  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 Company derives a significant portion of its net revenues from customers located in certain geographic regions or countries.  A significant portion of the Company’s net revenues come from customers located in South Korea. In the event that political tensions surrounding North Korea evolve into military or social conflict, or other factors disrupt the Korean economy, the Company’s revenues, results of operations, cash flow and financial condition could be adversely affected.  A significant portion of the Company’s net revenues come from customers located in Taiwan and China.  In the event that economic activity in these two countries declines, or is disrupted by geopolitical events, the Company’s revenues and results of operations could be adversely affected.

The Company is involved in litigation.  The Company is currently involved in one lawsuit where Micrel is the defendant.  Litigation is by its nature unpredictable and costly.  If the level of effort required to prosecute or defend the Company’s position in any lawsuit increases significantly, or if a judgment is entered against the Company, the resulting expense could adversely affect the Company’s financial condition, results of operations 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, in addition to litigation mentioned herein, 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.

18

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.  Based on the status of the litigation described above, the Company does not believe that any material and specific risk exists related to the loss of use of patents, products or processes.

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.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Overview

Micrel designs, develops, manufactures and markets a range of high-performance analog power ICs, mixed-signal and digital ICs.  These products address a wide range of end markets including cellular handsets, enterprise and portable computing, enterprise and home networking, wide area and metropolitan area networks and industrial equipment.  The Company also manufactures custom analog and mixed-signal circuits and provides wafer foundry services for customers who produce electronic systems for communications, consumer and military applications.

To enhance the readers' understanding of the Company's performance, the following chronological overview of the Company's results for the years 2005 through 2007 have been provided.

In the first quarter of 2005, demand as measured by order rates, improved substantially over fourth quarter of 2004 levels.  First quarter bookings increased by 40% over fourth quarter 2004 levels.  The improvement in order rates was driven by customers serving the industrial, computing and communications end markets. Bookings from Micrel’s major distributors increased in the first quarter after falling sharply in the second half of 2004 as distributors adjusted to shorter industry lead times and reduced their inventory levels.  Despite increased bookings during the first quarter and lean supply chain inventory levels, order lead times from Micrel's customers continued to average two to three weeks.

In the second quarter of 2005, the ongoing short lead time environment continued to cause customers to order only what was required for their short term needs.  Second quarter order rates declined from first quarter levels primarily due to lower order amounts from the Company’s distributors and certain customers serving the wireless handset end market.  Bookings from the Company’s major sell-through distributors declined from strong first quarter levels and were less than overall resales for the second quarter as distributors attempted to increase their inventory turns to improve their return on working capital.  In the wireless handset market, customers reduced both orders and production levels in coordination with efforts to reduce channel inventories of handsets.  Second quarter 2005 net revenues of $62.1 million increased sequentially by 2%, but were 10% less than the net revenues of the year ago period.  The Company continued to exercise pricing discipline for most of its products in an attempt to improve gross profit.  Consequently, sales of certain products, such as those serving the SOHO Ethernet market and the low end personal computer market, declined resulting in a lower rate of revenue growth for the Company.

Third quarter 2005 order rates increased substantially from second quarter levels, increasing sequentially in all geographic regions.  Throughout the third quarter, customers continued to place orders with short delivery requirements, even as the aggregate order level increased.  Order levels from the Company's distributors increased in the third quarter, returning to a level consistent with sales of Micrel’s products to their end customers. Third quarter net revenues increased sequentially by 1% to $62.5 million, but were 8% below the revenue level of the year ago period.

Continued broad based demand, combined with lean channel inventories and short lead times, resulted in higher order rates for the Company in the fourth quarter of 2005.  Order strength in the quarter from customers serving the industrial and communications end markets, and from the Company’s major distributors, resulted in the second highest quarterly booking level since calendar year 2000.  Net revenues increased 4% on a sequential basis in the fourth quarter to $65.1 million and were 10% above the net revenues in the year ago period.  Although order rates increased in the fourth quarter, customer lead times remained short, averaging three to four weeks.

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

In 2005, the Company’s gross margin improved continuously throughout the year, returning to levels recorded in the year 2000 despite significantly lower levels of revenue and capacity utilization.  The increase in gross margin was in part, due to better pricing discipline, improved sales mix of higher margin products, ongoing manufacturing cost reductions and lower depreciation expense as a result of disciplined capital spending.

In the first quarter of 2006, broad based strength in customer demand, combined with continued lean channel inventories resulted in the highest quarterly booking level for Micrel since calendar year 2000.  Orders from Micrel’s major sell-through distributors and from customers serving the communications and industrial end markets strengthened in the first quarter.  Net revenues increased 5% on a sequential basis to $68.2 million and were 12% above the net revenues of the year-ago period.  The sequential growth in net revenues was primarily the result of increased demand from customers serving the wireline communications end market and higher resales of the Company’s products through its distributors, partially offset by seasonal declines in sales to the wireless handset (primarily in Korea) and computing end markets.  First quarter of 2006 gross margin of 58.5% was the highest quarterly gross margin as of that time in the Company’s history.  The sequential improvement in gross margin was primarily the result of a richer sales mix driven by increased sales of higher margin wireline communications products.  The Company’s inventory increased on a sequential basis in response to higher demand and in order to provide competitive lead times to our customers.  The sequential increase in inventory added approximately one percentage point to first quarter gross margin, about the same as that experienced in the fourth quarter of 2005.

In the second quarter of 2006, overall order rates moderated from the levels experienced in the first quarter.  Second quarter 2006 net revenues of $70.2 million increased by 3% sequentially and were 13% above the prior year period.  The growth in net revenues continued to be led by demand from customers serving the wireline communications end market. This growth was partially offset by continued weakness in demand from Korean-based customers serving the wireless handset end market as they experienced a sequential decline in handset shipments during the second quarter.  Second quarter 2006 gross margin of 57.3% declined by 1.2 percentage points as compared to the first quarter of 2006 but was up 5.5 percentage points from the 51.8% reported for the comparable period in 2005.  The sequential decline in gross margin was primarily the result of normal fluctuations in sales mix and changes in inventory combined with a greater unfavorable impact from stock compensation expense.  The Company’s on-hand inventories increased by $1.5 million on a sequential basis.  The majority of the second quarter inventory growth was for purchased Ethernet product materials driven by increased customer demand coupled with long 3rd party foundry cycle times.

In the third quarter of 2006, overall order rates declined on a sequential basis, primarily because the Company’s sell-through distributors reduced orders and consumed backlog in an attempt to control inventory levels.  Orders from direct OEM customers increased slightly on a sequential basis in the third quarter primarily due to higher bookings from customers serving the wireless handset and computing end markets, and increased foundry orders.  Third quarter 2006 net revenues of $73.5 million increased by 5% sequentially and were 18% above the prior year period.  Continued strength from the industrial end market, combined with a rebound in the Company’s wireless handset business, led the product revenue growth in the third quarter.  Third quarter resales of the Company’s products through the distribution channel increased slightly in what is traditionally a seasonally slow period for North American and European distributors.  Sales to the wireline communications markets slowed in the quarter after rapid growth in the first half of 2006.  Third quarter 2006 net revenues included $2.9 million associated with a patent license that was previously under litigation.

24

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

Third quarter 2006 gross margin of 58.6% matched the highest level in the Company’s history.  The settlement of intellectual property matters, and related licensing revenues and expenses, resulted in $2.2 million of net pre-tax operating income in the third quarter, increasing third quarter 2006 net income by $0.02 per diluted share. The Company’s September ending on-hand inventory increased $2.6 million from the second quarter.  The majority of the inventory growth was for purchased material for Ethernet products, as manufacturing cycle times at the foundries that manufacture Ethernet products declined during the third quarter while end demand for certain Ethernet products decreased.

Fourth quarter 2006 order rates were slightly lower than the third quarter, and remained below the level of fourth quarter revenues as customers attempted to reduce inventory levels.  Fourth quarter net revenues were $64.5 million, a decrease of 12% from third quarter revenues of $73.5 million and 1% lower than revenues of $65.1 million recorded in the year-ago period.   The sequential decline in sales resulted primarily from reduced demand from wireless handset manufacturers combined with lower distribution revenues and the absence of patent license revenue.  Gross margin of 57.2% declined from the previous quarter primarily due to lower revenues and the impact of reduced manufacturing volumes leading to less absorption of fixed cost.  The Company’s inventory was flat on a sequential basis as the Company reduced manufacturing activity in response to reduced demand.

Micrel’s overall financial performance in 2006 was one of the best on an annual basis in the Company’s history.  Revenues of $276.3 million were the second highest annual amount ever recorded.  Total sales increased by 10.4% over the $250.4 million posted in 2005.  Gross margin of 57.9% improved for the fourth consecutive year and reached the highest level in the Company’s history, exceeding previous peak levels recorded in the year 2000 when revenues were 25% higher than 2006.  Income from operations of $57.8 million increased by 74% from the $33.1 million recorded in 2005.  Operating margin improved to 20.9% from 13.3% in 2005.  Year 2006 net income was $38.3 million, or $0.46 per diluted share, an increase of 50% from $25.4 million, or $0.29 per diluted share in 2005.  Year 2006 net income and earnings per share were the second highest ever recorded by Micrel on an annual basis.  Operating cash flow for the year of 2006 was $59 million.

During the first quarter of 2007, customers continued to control their inventories closely.  However, the order rates the Company experienced during the quarter suggested that customer and channel inventories had fallen to levels consistent with end demand.  Micrel’s first quarter bookings increased in all major geographic regions resulting in an 18% growth in orders compared with fourth quarter 2006 levels.  The total overall amount of new orders booked in the first quarter exceeded revenues.  The sequential improvement in bookings was driven by higher order levels from customers serving the high speed communications, wireless handset and industrial end markets.  Order rates increased for both OEM customers and sell-through distributors, while bookings from Micrel’s Asian-based sell-in distributors were flat from fourth quarter levels.  First quarter revenues were $63.1 million, 2% less than the $64.5 million recorded in the fourth quarter 2006 and 7% lower than the $68.2 million posted in the first quarter of 2006.  Seasonal declines in sales to customers serving the computing, wireless handset and consumer end markets were partially offset by higher resales through the Company’s sell-through distributors.  Gross margin increased sequentially to 58.1% despite lower revenues and inventory reduction due to a combination of lower manufacturing costs and a higher gross margin sales mix.  First quarter operating profit was $11.3 million, or 18% of sales.  The Company’s on-hand inventory declined on a sequential basis.  Overall channel inventories remained relatively flat from the end of 2006, with increases at the Company’s sell-through distributors offset by lower inventory levels at Micrel’s sell-in distributors.

25

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

In the second quarter of 2007, order lead times remained in the four to six week range.  Although customers continued to closely monitor their inventories, the dollar amount of second quarter bookings exceeded the Company’s revenue level.  Second quarter revenues were $65.1 million, a sequential increase of 3% over the $63.1 million recorded in the first quarter, and 7% lower than the $70.2 million posted in the year-ago period.   The sequential growth in second quarter revenues was led by increased sales to customers serving the communications and computing end markets, offsetting lower sales of the Company’s products to major Korean wireless handset customers.  Gross margin of 57.0% was flat to the prior year period and decreased by approximately 1% from the first quarter.  During the second quarter, the Company operated at a lower level of factory utilization, which had the combined effect of reducing both inventory levels and gross margin.  Channel inventories also declined on a sequential basis as the Company’s major global sell-through distributors attempted to take advantage of readily available semiconductor component supplies to increase their working capital turns.

Demand for the Company's products in the third quarter of 2007 was generally seasonal in nature.  Bookings from industrial and wireline communication customers softened, while holiday and back-to-school related markets such as wireless handsets, computing and consumer were more robust.  Faced with concerns about the growth of the U.S. economy, the Company’s sell-through distributors were cautious throughout the third quarter as they saw their orders slow and inventories build.  The overall amount of orders booked by the Company in the third quarter was approximately the same as the revenue level for the quarter.  Customers continued to control their inventories very closely during the third quarter in the face of short lead times, due in part to their belief that the semiconductor industry had sufficient inventory and/or the ability to deliver sufficient quantities to meet customer demand in this shorter lead time environment.  Micrel’s order lead times decreased throughout the quarter, starting out at about five weeks in July and declining to three to four weeks in September.  Third quarter revenues were $65.2 million, up slightly compared to the second quarter, and 11% lower than the $73.5 million posted in the year-ago period.  An increase in third quarter sales to customers in the wireless handset and consumer end market was offset by lower revenues from customers in the wireline communications end market, arising from lower shipments to major Chinese communications customers as they trimmed inventory levels.  Gross margin increased from 57.0% in the second quarter to 57.5% in the third quarter of 2007, and decreased from 58.6% in the year ago period.  During the third quarter, the Company reduced on-hand inventory levels despite a higher level of factory utilization.  Channel inventories increased by approximately one week over the second quarter due to seasonally slower distribution sales of the Company’s products.  Third quarter operating profit was $12.9 million, or 19.8% of revenues.

In the fourth quarter of 2007, the increasingly uncertain macroeconomic environment appeared to heighten our customer’s focus on maintaining lean inventories.  Global distributors and certain OEM customers informed the Company that they attempted to minimize inventory at year-end.  As a consequence, customer orders and purchases declined more quickly than usual in the month of December, resulting in a quarterly book-to-bill ratio of less than one, and impacting fourth quarter revenues.  Revenues for the fourth quarter of 2007 decreased 1% from the third quarter to $64.6 million and were essentially flat to the revenues in the year-ago period.  Sales to customers serving the consumer, computing and the wire line communications end markets declined on a sequential basis, partially offset by increased sales of the Company’s Ethernet products during the quarter.  Gross margin decreased to 55.8% in the fourth quarter from 57.5% in the third quarter primarily as a result of a less favorable sales mix.  Fourth quarter operating profit was $11.7 million, or 18% of revenues.  On-hand inventories increased during the fourth quarter, while channel inventories decreased by approximately one week from the end of the third quarter.

26

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

Micrel’s financial performance in 2007 remained solid.  Total year gross margin of 57% was the second highest in the Company history.  Net income for fiscal 2007 increased 15.8% to $44.4 million, or $0.57 per diluted share, compared with net income of $38.3 million, or $0.46 per diluted share in 2006.  Included in 2007 pre-tax income was a $15.5 million gain associated with a first quarter legal settlement, which after income taxes, was equivalent to $9.9 million or $0.13 per diluted share.  Cash flows from operations of $67.8 million during the year enabled the repurchase of 5.5 million shares of common stock for $55.1 million, representing approximately 7% of the shares outstanding at the beginning of the year.  In addition, the Company commenced a $0.03 per common share cash dividend payment to shareholders in the second quarter of 2007.

The Company derives a substantial portion of its net revenues from standard products. For 2007, 2006 and 2005 the Company's standard products sales accounted for 92%, 93%, and 96%, respectively, 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 internal 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 of new products.  These and other factors are described in further detail later in this discussion and in Item 1A.  As a result of the foregoing or other factors, 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 Form 10-K 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. For a detailed discussion of the Company's significant accounting policies, see Note 1 of Notes to Consolidated Financial Statements. The Company considers certain accounting policies related to revenue recognition, inventory valuation, share-based accounting, income taxes, and litigation to be critical to the fair presentation of its financial statements.

27

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

Revenue Recognition and Receivables. Micrel generates revenue by selling products to OEM's, 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 recognition and related cost of sales are deferred, 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 Asian based 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.

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. This treatment is in accordance with Accounting Research Bulletin 43 and SEC Staff Accounting Bulletin 100 "Restructuring and Impairment Charges."

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

Share-Based Compensation. Effective January 1, 2006, Micrel adopted the provisions of SFAS No. 123R using the modified-prospective transition method. Under SFAS No. 123R 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, SFAS No. 123R requires an estimate of expected forfeiture rates of stock grants and share-based compensation expense is to be 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 December 31, 2007, 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.

Effective January 1, 2007, the Company adopted the provisions of FASB Interpretation (FIN) No. 48, Accounting for Uncertainty in Income Taxes - an interpretation of FASB Statement No. 109. FIN No. 48 contains a two-step approach to recognizing and measuring uncertain tax positions accounted for in accordance with SFAS No. 109. 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. See Note 7 of Notes to Consolidated Financial Statements for additional information regarding the adoption of FIN No. 48.

Litigation.  The semiconductor industry is characterized by frequent litigation regarding patent and other intellectual property rights.  In the past two years, the Company has concluded cases involving intellectual property claims (see Note 10 of Notes to Consolidated Financial Statements).  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. Net revenues decreased 7% to $258.0 million for the year ended December 31, 2007 from $276.3 million in 2006 due to decreased standard product revenues which were partially offset by increased other products revenues.

Standard product revenues decreased 8% to $237.4 million, which represented 92% of net revenues for the year ended December 31, 2007, compared to $258.2 million and 93% of net revenues for 2006. These decreases resulted primarily from decreased shipments of standard products to the wireless handset, computer products, telecommunications, networking and high speed communications end markets, which were partially offset by increase unit shipments to the industrial end market.

Other products revenues which consist primarily of custom and foundry products revenues and revenues from the license of patents, increased 14% to $20.6 million, which represented 8% of net revenues for the year ended December 31, 2007, compared to $18.1 million and 7% of net revenues for 2006. These increases resulted primarily from increased foundry product shipments, which were partially offset by a $2.9 million patent license included in 2006.

For the year ended December 31, 2006, net revenues increased 10% to $276.3 million from $250.4 million in 2005 due to increased standard product revenues and increased other products revenues. Standard product revenues increased 8% to $258.2 million, which represented 93% of net revenues for 2006, compared to $239.2 million and 96% of net revenues for 2005. These increases resulted primarily from increased shipments of standard products to the industrial, networking and high-speed communications end markets. Other products revenues which consist primarily of custom and foundry products revenues and revenues from the license of patents, increased 62% to $18.1 million, which represented 7% of net revenues for 2006, compared to $11.2 million and 4% of net revenues for 2005. These increases partially resulted from a $2.9 million patent license included in 2006 combined with increased shipments of foundry and custom products.

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

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.  During 2007, the Company averaged approximately 50% to 60% OEM turns fill per quarter compared to approximately 50% to 55% turns fill per quarter during 2006.

As noted in Item 1A “Risk Factors” and in the overview section of this Item 7 “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.  To deal with these market forces while maintaining reliable service levels, the Company and other semiconductor suppliers are carrying higher relative levels of inventory compared with historical averages prior to 2001.  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.

International sales represented 67%, 70%, and 75% of net revenues for the years ended December 31, 2007, 2006 and 2005, respectively. On a dollar basis, international sales decreased 10% to $173.6 million for the year ended December 31, 2007 from $193.5 million for the comparable period in 2006. These decreases resulted primarily from decreased shipments of standard products to the networking communications, wireless handsets and computer products end markets, primarily in Asia.

The trend for the Company’s customers to move their electronics manufacturing to Asian countries has brought 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 except by price. 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.

Share-Based Compensation. Effective January 1, 2006, the Company adopted the fair value recognition provisions of SFAS No. 123R using the modified prospective transition method and therefore has not restated results for prior periods. The Company's results of operations for the years ended December 31, 2007 and 2006 were impacted by the recognition of non-cash expense related to the fair value of share-based compensation awards. During 2007, Micrel recorded $5.5 million in pre-tax share-based compensation expense, of which $1.2 million is included in cost of revenues, $2.1 million is included in research and development expense and $2.2 million is included in sales, general and administrative expense. During 2006, Micrel recorded $8.4 million in pre-tax share-based compensation expense, of which $1.5 million is included in cost of revenues, $3.4 million is included in research and development expense and $3.5 million is included in sales, general and administrative expense.

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

Prior to January 1, 2006, the Company accounted for share-based awards to employees using the intrinsic value method in accordance with Accounting Principles Board Opinion ("APB") No. 25, "Accounting for Stock Issued to Employees". During the years 1996 through December 2001, certain of the Company's option pricing practices resulted in stock compensation expense under APB No. 25. In addition, the Company assumed certain stock options granted to employees of Kendin Communications in connection with the acquisition of Kendin Communications in 2001 which were compensatory under APB No. 25. For the year ended December 31, 2005, total amortization of deferred stock compensation was $770,000.

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 decreased to 57% for the year ended December 31, 2007 from 58% for 2006. The decrease in gross margin resulted primarily from reduced revenue levels to cover fixed manufacturing costs. Depreciation and amortization as a percent of sales increased to 7.0% for 2007 as compared to 6.3% for 2006 due to additional depreciation on new equipment purchases combined with a decrease in annual revenues. The 2007 gross margin was also affected by a greater sales mix of lower margin products and lower revenues from the license of patents.

For the year ended December 31, 2006, the Company's gross margin increased to 58% from 53% for 2005. The increases in gross margin resulted primarily from a greater sales mix of higher margin products combined with decreased depreciation, decreased wafer fabrication costs and decreased external assembly and test costs, which were partially offset by increased share-based compensation costs due to the adoption of SFAS No. 123R.  Depreciation and amortization as a percent of sales declined to 6.3% for 2006 as compared to 8.0% for 2005. This reduction in depreciation was primarily due to existing equipment becoming fully depreciated, which was partially offset by additional depreciation on new equipment purchases. In addition, included in gross profit for 2006 is $2.9 million in net revenues for a patent license (see Note 10 of Notes to Consolidated Financial Statements), which is partially offset by a $714,000 charge to cost of revenues related to the settlement of a patent dispute (see Note 10 of Notes to Consolidated Financial Statements).

Research and Development Expenses.  Research and development expenses as a percentage of net revenues represented 21% and 19% for the years ended December 31, 2007 and 2006, respectively. On a dollar basis, research and development expenses increased $2.4 million or 5% to $54.5 million for 2007 from $52.1 million in 2006. These increases were primarily due to increased 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.

For the year ended December 31, 2006, research and development expenses increased $6.8 million to $52.1 million from $45.2 million in 2005. This increase was primarily due to increased share-based compensation costs due to the adoption of SFAS No. 123R combined with increased prototype fabrication costs.

Selling, General and Administrative Expenses. As a percentage of net revenues, selling, general and administrative expenses represented 18% for both of the years ended December 31, 2007 and 2006. On a dollar basis, selling, general and administrative expenses decreased $4.0 million or 8% to $45.0 million for 2007 from $49.0 million for 2006. This decrease was primarily due to decreased outside legal costs.

32

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

For the year ended December 31, 2006 selling, general and administrative expenses increased $2.9 million to $49.0 million from $46.2 million for 2005. These increases were primarily due to increased share-based compensation costs due to the adoption of SFAS No. 123R and increased staffing costs, including salaries and sales commissions, which were partially offset by decreased outside legal costs.

Restructuring Expense. In September 2002, the Company approved a plan to close its Santa Clara, California wafer fabrication facility to reduce costs and improve operating efficiencies.  During 2003, the Company ceased all manufacturing processes within the Santa Clara facility and completed the relocation of all employees to its San Jose, CA facilities.  As of December 31, 2007, the remaining restructuring accrual related to this facility closure was $1.8 million (see Note 12 of Notes to Consolidated Financial Statements) and is classified as other current liabilities. Actual future costs may be different than these estimates and would require an adjustment to restructuring expense in the period such determination is made.

Other Operating Expense.  Other operating expenses in 2006 consist primarily of accrued costs related to the settlement of patent infringement lawsuits (see Note 10 of Notes to Consolidated Financial Statements).  In 2005, the Company recorded $9.3 million in other operating expense related to a jury verdict against Micrel in its suit against TRW Automotive and for TRW Automotive in its countersuit against Micrel. (see Note 10 of Notes to Consolidated Financial Statements).

Other Income, Net. 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 and accrued interest related to accrued litigation liabilities.  During 2007 the Company recorded $15.5 million in non-operating income resulting from the settlement of litigation (see Note 10 of Notes to Consolidated Financial Statements).

Provision for Income Taxes. For the year ended December 31, 2007, the provision for income taxes was $24.9 million or 36% of income before taxes as compared to 39% of income before taxes for 2006.  The tax rate decrease is due primarily to the reduction in nondeductible share-based compensation expense combined with an increased effect of federal and state research and development credits. The 2007 provision for income taxes differs from taxes computed at the federal statutory rate primarily due to the effects of non-deductible share-based compensation expense, state income taxes, federal and state research and development credits and federal qualified production activity deductions.

For the year ended December 31, 2006, the provision for income taxes was $24.9 million or 39% of income before taxes as compared to 32% of income before taxes for the comparable period in 2005.  The tax rate increase is due primarily to the effects of nondeductible share-based compensation expense combined with a reduced impact of federal qualified production activity deductions and federal and state research and development credits as a result of significantly increased income before tax in 2006. The provision for income taxes differs from taxes computed at the federal statutory rate primarily due to the effect of nondeductible share-based compensation expense, state income taxes, state research and development credits, and federal qualified production activity deductions.

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 December 31, 2007, consisted of cash and short-term investments of $91.1 million and a $6.0 million revolving line of credit from a commercial bank under which the Company could borrow $5.5 million (see Note 5 of Notes to Consolidated Financial Statements).

33

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

The Company generated $67.8 million in cash flows from operating activities for the year ended December 31, 2007, which was primarily attributable to net income, after adding back non-cash activities, of $71.9 million (net income of $44.4 million plus non-cash activities of $27.5 million consisting primarily of $18.0 million in depreciation and amortization and $5.5 million in share-based compensation). This cash flow was partially offset by a $10.0 million decrease in other current liabilities, resulting primarily from the payment of a legal judgment.

For the year ended December 31, 2006, the Company generated $59.0 million in cash flows from operating activities, which was primarily attributable to net income, after adding back non-cash activities, of $62.7 million (non-cash activities consisted primarily of $17.2 million in depreciation and amortization and $8.4 million in share-based compensation) combined with a $4.4 million decrease in accounts receivable and a $7.6 million increase in deferred income on shipments to distributors, which were partially offset by $6.5 million increase in inventories combined with a $4.9 million decrease in income taxes payable and a $3.1 million decrease in accounts payable.

The Company used $29.3 million of cash for investing activities during the year ended December 31, 2007, which was primarily comprised of $20.2 million in purchases of property, plant and equipment and $11.6 million from the net purchases of investments, which was partially offset by a $2.6 million decrease in restricted cash.

For the year ended December 31, 2006, the Company generated $12.4 million of cash from investing activities, which was primarily comprised of $33.4 million from the net proceeds from the sale of short-term investments, which was partially offset by $16.8 million in purchases of property, plant and equipment, $1.6 million in purchases of intangible assets and $2.6 million increase in restricted cash (see Note 1 of Notes to Consolidated Financial Statements).

The Company used $49.8 million of cash for financing activities during the year ended December 31, 2007, primarily for the repurchase of $55.1 million of the Company's common stock and $6.9 million for the payment of cash dividends, which were partially offset by $12.1 million in proceeds from employee stock transactions.

For the year ended December 31, 2006, the Company used $67.3 million of cash in financing activities, primarily for the repurchase of $71.5 million of the Company's common stock, which was partially offset by $4.1 million in proceeds from employee stock transactions.

The Company currently intends to spend approximately $16 million to $23 million to purchase capital equipment and make facility improvements during the next twelve months primarily for manufacturing equipment for wafer fabrication and product testing and additional research and development related software and equipment. The Company is currently authorized by its Board of Directors to repurchase an additional $50 million of its common stock through December 31, 2008. Since inception, the Company's principal sources of funding have been its cash from operations, bank borrowings and sales of common stock. 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 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.

34

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

At December 31, 2007, the Company held $16.6 million in long-term investments (see discussion of investments in Note 1 of Notes to Consolidated Financial Statements).  Long-term investments consisted of senior auction rate notes secured by student loans. In February 2008, some of these auction rate securities failed to auction successfully due to sell orders exceeding buy orders. The Company is evaluating the impact of these failed auctions on the fair value of these securities.  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.

Recently Issued Accounting Standards

Please refer to the caption "New Accounting Standards" within Note 1 of Notes to Consolidated Financial Statements for a discussion of the expected impact of recently issued accounting standards.

Contractual Obligations and Commitments

As of December 31, 2007, the Company had the following contractual obligations and commitments (in thousands):

	Payments Due By Period
	Total		Less than 1 Year		1-3 Years		4-5 Years		After 5 Years
Operating leases (see Note 8 of Notes to Consolidated Financial Statements)	$	5,341	$	1,911	$	2,844	$	571	$	15
Open purchase orders		13,700		13,700		—		—		—
Total	$	19,041	$	15,611	$	2,844	$	571	$	15

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 a $6.0 million revolving line of credit from a commercial bank under which the Company could borrow $5.5 million. The revolving line of credit agreement includes a provision for the issuance of commercial or standby letters of credit by the bank on behalf of the Company. The value of all letters of credit outstanding reduces the total line of credit available. There were no borrowings under the revolving line of credit at December 31, 2007 and there were $525,000 in standby letters of credit outstanding. The letters of credit are issued to guarantee payments for the Company's workers compensation program.

Effective January 1, 2007, the Company adopted the provisions of FIN No. 48 (see Note 7 of Notes to Consolidated Financial Statements). As of December 31, 2007, the liability for uncertain tax positions, net of federal impacts on state tax issues was $5.4 million, of which none is expected to be paid within one year.  Included in the $5.4 million is $2.6 million that has not yet reduced income tax payments, and, therefore, has been netted against non-current deferred tax assets.  The remaining $2.8 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 has no other off-balance sheet arrangements and has not entered into any transactions involving unconsolidated, limited purpose entities or commodity contracts.

35

ITEM7 A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

At December 31, 2007, the Company held $10.2 million in short-term investments. Short-term investments consist primarily of liquid debt instruments and are classified as available-for-sale securities. The short-term investments held at December 31, 2007 are primarily fixed rate securities. These available-for-sale securities are subject to interest rate risk and will fall in value if market interest rates increase. If market interest rates were to increase immediately and uniformly by 10 percent from levels at December 31, 2007, the fair value of the short-term investments would decline by an immaterial amount.

       At December 31, 2007, the Company held $16.6 million in long-term investments. Long-term investments consisted of senior auction rate notes secured by student loans. In February 2008, some of these auction rate securities failed to auction successfully due to sell orders exceeding buy orders. The Company is evaluating the impact of these failed auctions on the fair value of these securities.  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. For additional information regarding the Company's investments, see Note 1 of Notes to Consolidated Financial Statements under the caption “Investments” in Item 15 of Part III which is incorporated herein by reference.

At December 31, 2007, the Company had no fixed-rate long-term debt subject to interest rate risk.

ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA

The Company’s financial statements are set forth on pages 39 through 69 and supplementary data are set forth on pages 70 through 71, which follow Item 15.

ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE

Not applicable.

ITEM 9A. CONTROLS AND PROCEDURES

Conclusion Regarding the Effectiveness of Disclosure 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 December 31, 2007.

Management’s Report on Internal Control Over Financial Reporting

The Company's management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rule 13a-15(f).  The Company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with U.S. generally accepting accounting principles.  Internal control over financial reporting cannot provide absolute assurance of achieving financial reporting objectives because of its inherent limitations. Internal control over financial reporting is a process that involves human diligence and compliance and is subject to lapses in judgment and breakdowns resulting from human failures. Internal control over financial reporting also can be circumvented by collusion or improper management override. In addition, any projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate due to changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. Because of such limitations, there is a risk that material misstatements may not be prevented or detected on a timely basis by internal control over financial reporting. However, these inherent limitations are known features of the financial reporting process. Therefore, it is possible to design into the process safeguards to reduce, though not eliminate, this risk.  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 internal control over financial reporting based on the criteria set forth in the report entitled "Internal Control - Integrated Framework"issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on its evaluation under the criteria set forth in the Internal Control — Integrated Framework, management has concluded that the Company's internal control over financial reporting was effective as of December 31, 2007.

The effectiveness of the Company’s internal control over financial reporting as of December 31, 2007 has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their report which appears in Part IV, Item 15 “Exhibits and Financial Statement Schedules” of this report.

Changes in Internal Control Over Financial Reporting

There has been no change in the Company’s internal controls over financial reporting that occurred during the quarter ended December 31, 2007 that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Shareholders' of Micrel Incorporated:

In our opinion, the consolidated financial statements listed in the index appearing under Item 15(a) (1) present fairly, in all material respects, the financial position of Micrel Incorporated and its subsidiaries at December 31, 2007 and 2006, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2007 in conformity with accounting principles generally accepted in the United States of America.  In addition, in our opinion, the financial statement schedule listed in the index appearing under Item 15(a)(2) presents fairly, in all material respects, the information set forth therein when read in conjunction with the related consolidated financial statements.  Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2007, based on criteria established in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).  The Company's management is responsible for these financial statements and financial statement schedule, for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in Management’s Report on Internal Control Over Financial Reporting appearing under Item 9A.  Our responsibility is to express opinions on these financial statements, on the financial statement schedule, and on the Company's internal control over financial reporting based on our integrated audits.  We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States).  Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects.  Our audits of the financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation.  Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk.  Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

As discussed in Note 6 to the consolidated financial statements, the Company changed the manner in which it accounts for share-based compensation in 2006.

As discussed in Note 7 to the consolidated financial statements, the Company changed the manner in which it accounts for uncertainty in income taxes in 2007.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles.  A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

40

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements.  Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Years Ended December 31, 2007, 2006 and 2005

1. SIGNIFICANT ACCOUNTING POLICIES

Nature of Business —Micrel, Incorporated and its wholly-owned subsidiaries (the “Company”) develops, manufactures and markets analog, mixed-signal and digital semiconductor devices. The Company also provides custom and foundry services which include silicon wafer fabrication, integrated circuit ("IC") assembly and testing. The Company’s standard ICs are sold principally in North America, Asia, and Europe for use in a variety of products, including those in the computer, communication, and industrial markets. The Company’s custom circuits and wafer foundry services are provided to a wide range of customers that produce electronic systems for communications, consumer, automotive and military applications. The Company produces the majority of its wafers at the Company’s wafer fabrication facilities located in San Jose, California. After wafer fabrication, the completed wafers are then separated into individual circuits and packaged at independent assembly and final test contract facilities primarily located in Malaysia.

Basis of Presentation —The accompanying consolidated financial data has been prepared by the Company pursuant to the rules and regulations of the U.S. Securities and Exchange Commission ("SEC") and is in conformity with U.S. generally accepted accounting principles ("US GAAP").

Principles of Consolidation —The accompanying consolidated financial statements include the accounts of Micrel, Incorporated and its wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated.

Use of Estimates —In accordance with accounting principles generally accepted in the United States of America, management utilizes certain 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. The primary estimates underlying the Company's financial statements include allowances for doubtful accounts receivable, allowances for product returns and price adjustments, provisions for obsolete and slow moving inventory, share-based compensation, income taxes, litigation and accrual for other liabilities. Actual results could differ from those estimates.

Cash Equivalents —The Company considers all highly liquid debt instruments purchased with remaining maturities of three months or less to be cash equivalents.

Restricted Cash — During the first quarter of 2006, the Company elected to post a surety bond to stay payment of potential damages and interest arising from a legal judgment awarded to TRW during 2005 (see Note 10).  As collateral for the surety bond, the Company placed $2.6 million in a registered pledge account.  The amount pledged was classified as Restricted Cash in the Company’s Consolidated Balance Sheet as of December 31, 2006. During the second quarter of 2007, the Company paid the legal judgment to TRW and the $2.6 million balance of the registered pledge account was transferred to the Company's unrestricted cash account.

Investments —Short-term investmentsconsist primarily of liquid corporate debt instruments and are classified as available-for-sale securities and 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. 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 regards to those securities (expectations of sales and redemptions).  A summary of investments at December 31, 2007 and 2006 is as follows (in thousands):

	Amortized  Cost		Market  Value		Unrealized Holding Gains		Unrealized Holding Losses
Short-term investments at December 31, 2007	$	10,177	$	10,150	$	—	$	27
Short-term investments at December 31, 2006	$	15,085	$	15,050	$	—	$	35

Long-term investments of $16.6 million at December 31, 2007, consist of senior auction rate notes secured by student loans. 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 well in excess of ten years. At the end of each reset period, which occurs every twenty eight days for the securities held by the Company, investors can sell or continue to hold the securities at par. In February 2008, 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 four of the six student loan-backed notes held by the Company have failed as of February 27, 2008. 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 has classified all auction rate notes as long-term assets in the consolidated balance sheet as of December 31, 2007. 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 December 31, 2007, the maximum interest rate is generally one month LIBOR plus 1.5% based on the notes’ AAA rating as of that date. The Company is evaluating the impact of these failed auctions on the fair value of these securities. If the Company determines that the fair value of these auction rate securities is temporarily impaired, the Company would record a temporary impairment, within other comprehensive loss, a component of shareholders' equity, in the period such temporary decline in fair value is determined.  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.

	Amortized  Cost		Market  Value		Unrealized Holding Gains		Unrealized Holding Losses
Long-term investments at December 31, 2007	$	16,557	$	16,552	$	—	$	5

Certain Significant Risks and Uncertainties —Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash and cash equivalents, investments and accounts receivable. Risks associated with cash are mitigated by banking with creditworthy institutions. Cash equivalents and investments consist primarily of commercial paper, bank certificates of deposit, money market funds and auction rate securities and are regularly monitored by management. Credit risk with respect to the trade receivables is spread over geographically diverse customers. The Company performs ongoing credit evaluations of its customers and maintains an allowance for potential credit losses. At December 31, 2007, two world-wide distributors and an Asian based stocking representative, accounted for 18%, 10% and 15%, respectively, of total accounts receivable. At December 31, 2006, two world-wide distributors and an Asian based stocking representative, accounted for 20%, 13% and 12%, respectively, of total accounts receivable.

Micrel currently purchases certain components from a limited group of vendors. The packaging of the Company's products is performed by, and certain of the raw materials included in such products are obtained from, a limited group of suppliers. The wafer supply for the Company’s Ethernet products is currently dependent upon two large third-party wafer foundry suppliers. Although the Company seeks to reduce its dependence on limited source suppliers, disruption or termination of any of these sources could occur and such disruptions could have an adverse effect on the Company's financial condition, results of operations, or cash flows.

The Company participates in a dynamic high technology industry and believes that changes in any of the following areas could have a material adverse effect on the Company’s future financial position, results of operations, or cash flows: changes in the overall demand for products offered by the Company; competitive pressures in the form of new products or price reductions on current products; advances and trends in new technologies and industry standards; changes in product mix; changes in third-party manufacturers; changes in key suppliers; changes in certain strategic relationships or customer relationships; litigation or claims against the Company based on intellectual property, patents (see Note 10), product, regulatory or other factors; risks associated with the ability to obtain necessary components; risks associated with the Company’s ability to attract and retain employees necessary to support its growth.

Inventories — 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. Once an inventory write-down provision is established, it is maintained until the product to which it relates is sold or otherwise disposed of. This treatment is in accordance with Accounting Research Bulletin 43 and Staff Accounting Bulletin 100 "Restructuring and Impairment Charges."

Property, Plant and Equipment —Equipment, building and leasehold improvements are stated at cost and depreciated using the straight-line method. Equipment is depreciated over estimated useful lives of three to five years. Buildings are depreciated over an estimated useful life of thirty years. Building improvements are depreciated over estimated useful lives of fifteen to thirty years. Leasehold improvements are amortized over the shorter of the lease term or the useful lives of the improvements which is generally 3 to 5 years.

Intangible Assets — The Company applies the provisions of SFAS No. 144 in evaluating whether any impairment indicators exist for intangible assets and has determined that its intangible assets were not impaired at December 31, 2007 and 2006. Acquired technology, patents and other intangible assets continue to be amortized over their estimated useful lives of 3 to 7 years using the straight-line method. Components of intangible assets were as follows (in thousands):

	As of December 31, 2007						As of December 31, 2006
	Gross Carrying Amount		Accumulated Amortization		Net Carrying Amount		Gross Carrying Amount		Accumulated Amortization		Net Carrying Amount
Developed and core technology	$	8,718	$	8,349	$	369	$	8,718	$	8,078	$	640
Patents and tradename		10,318		7,661		2,657		10,318		6,244		4,074
Customer relationships		1,455		1,455		-		1,455		1,455		-
	$	20,491	$	17,465	$	3,026	$	20,491	$	15,777	$	4,714

Total intangible amortization expense for the years ended December 31, 2007, 2006 and 2005 was $1.7 million, $1.6 million and $1.6 million, respectively. Estimated future intangible amortization expense for intangible assets as of December 31, 2007, is expected to be approximately $1.7 million in 2008, $828,000 in 2009, and $254,000 in 2010 and 2011.

Impairment of Long-Lived Assets —Pursuant to SFAS No. 144, “Accounting for the Impairment or Disposal of Long-Lived Assets,” the Company periodically assesses whether long-lived assets have been impaired. An asset is initially evaluated for impairment if its estimated future undiscounted cash flows are less than the carrying value recorded on the Company's balance sheet. If a shortfall exists, any impairment is measured based on the difference between the fair value and the carrying value of the long-lived asset. The Company's estimate of fair value is based on either fair market value information, if available, or based on the net present value of expected future cash flows attributable to the asset. Predicting future cash flows attributable to a particular asset is difficult, and requires the use of significant judgment.

Revenue Recognition and Receivables — Micrel generates revenue by selling products to original equipment manufacturers ("OEM"s), 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 to a lesser extent 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 recognition and related cost of sales are deferred, 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, the Company

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

Years Ended December 31, 2007, 2006 and 2005

may offer to its distributors, where revenue is deferred upon shipment and recognized on a sell-through basis, price adjustments 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 Asian based 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.

The Company's accounts receivables balances represent trade accounts receivables which have been recorded at invoiced amount and do not bear interest.  The Company 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.

Litigation — 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.

Warranty Costs — The Company warrants products against defects for a period of up to 30 days. The majority of Micrel's product warranty claims are settled through the return of defective product and the reshipment of replacement product. Warranty returns are included in Micrel's allowance for returns, which is based on historical return rates. Actual future returns could be different than the returns allowance established. In addition, Micrel accrues a liability for specific warranty costs that are expected to be settled other than through product return and replacement. As of December 31, 2007 and 2006, respectively, accrued warranty expenses were immaterial amounts. Future actual warranty costs may be different from the accrued warranty expense.

Research and Development Expenses — Research and development expenses are recognized as incurred and consist primarily of payroll and other headcount related costs and cost of materials associated with the development of new wafer fabrication processes and the definition, design and development of standard products. The Company also expenses prototype wafers and new production mask sets related to new products as research and development costs until products based on new designs are fully characterized by the Company and are demonstrated to support published data sheets and satisfy reliability tests.

Self Insurance — The Company utilizes third-party insurance subject to varying retention levels or self insurance. The Company is self insured for a portion of the losses and liabilities primarily associated with earthquake damage, workers’ compensation claims and health benefit claims. Losses are accrued based upon the Company’s estimates of the aggregate liability for claims incurred using historical experience and certain actuarial assumptions followed in the insurance industry.

Advertising Expenses — The Company expenses advertising costs to selling, general and administrative expense as incurred. Advertising expenses for 2007, 2006 and 2005 were $2.0 million, $2.1 and $1.8 million respectively.

Income Taxes — Deferred tax assets and liabilities result from temporary differences between book and tax bases of assets and liabilities, state and federal research and development credit carryforwards, and state manufacturers credit carryforwards.  The Company had net current deferred tax assets of $19.4 million and net long-term deferred tax assets of $9.3 million as of December 31, 2007.  The Company must 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.

In addition, the calculation of the Company's tax liabilities involves dealing with uncertainties in the application of complex tax regulations.  Effective January 1, 2007, the Company adopted the provisions of FASB Interpretation (FIN) No. 48, Accounting for Uncertainty in Income Taxes - an interpretation of FASB Statement No. 109.  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 (see Note 7 for additional information regarding the adoption of FIN No. 48).

Share-based Compensation — As of January 1, 2006, the Company adopted SFAS No. 123(R), Share-Based Payment, ("SFAS 123(R)"), which requires companies to recognize in the statement of operations the grant-date fair value of stock awards issued to employees and directors. The Company adopted SFAS 123(R) using the modified prospective transition method. In accordance with the modified prospective transition method, the Company’s Consolidated Financial Statements for prior periods have not been restated to reflect the impact of SFAS 123(R) (see Note 6). Prior to the adoption of SFAS 123(R), the Company applied Accounting Principles Board Opinion No. 25 ("APB 25"), Accounting for Stock Issued to Employees, and related interpretations to account for awards of share-based compensation granted to employees.

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

	Years Ended December 31,
	2007		2006		2005
Weighted-average common shares outstanding		76,918		81,550		87,055

Shares used in computing diluted earnings per share		77,813		82,842		87,971

For the years ended December 31, 2007, 2006 and 2005, 6.4 million, 5.7 million and 7.2 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 are anti-dilutive.

Fair Value of Financial Instruments — Financial instruments included in the Company’s consolidated balance sheets at December 31, 2007 and 2006, consist of cash, cash equivalents, accounts receivable, accounts payable and investments. For cash, the carrying amount is the fair value. The carrying amount for cash equivalents, accounts receivable and accounts payable approximates fair value because of the short maturity of those instruments. The fair value of investments are based on quoted market prices.

New Accounting Standards — In July 2006, the Financial Accounting Standards Board ("FASB") issued FASB Interpretation No. 48, "Accounting for Uncertainty in Income Taxes, an Interpretation of FASB Statement No. 109" ("FIN No. 48"). FIN No. 48 clarifies the accounting for uncertainty in income taxes recognized in an enterprise's financial statements in accordance with SFAS No. 109 "Accounting for Income Taxes".  This interpretation prescribes a model for the financial statement recognition, measurement, presentation and disclosure of uncertain tax positions taken or expected to be taken in income tax returns. See Note 7 for additional information, including the effects of adoption on the Company’s Consolidated Financial Statements.

In September 2006, the FASB issued Statement 157, “Fair Value Measurements” (“SFAS 157”). SFAS 157 establishes a framework for measuring fair value by providing a standard definition of fair value as it applies to assets and liabilities. SFAS 157, which does not require any new fair value measurements, clarifies the application of other accounting pronouncements that require or permit fair value measurements. The effective date for the Company is January 1, 2008. The Company is currently evaluating the effect that the adoption of SFAS 157 will have on its financial position and results of operations.

In February 2007, the FASB issued Statement 159, "The Fair Value Option for Financial Assets and Financial Liabilities ("SFAS 159"). The new Statement allows entities to choose, at specified election dates, to measure eligible financial assets and liabilities at fair value in situations in which they are not otherwise required to be measured at fair value. If a company elects the fair value option for an eligible item, changes in that item's fair value in subsequent reporting periods must be recognized in current earnings. SFAS 159 also establishes presentation and disclosure requirements designed to draw comparison between entities that elect different measurement attributes for similar assets and liabilities. SFAS 159 is effective for fiscal years beginning after November 15, 2007. The Company is currently evaluating the effect that the adoption of SFAS 159 will have on its financial position and results of operations.

In December 2007, the FASB issued SFAS No. 141(R), “Business Combinations” (“SFAS 141(R)”), which replaces FAS 141. SFAS 141(R) establishes principles and requirements for how an acquirer in a business combination recognizes and measures in its financial statements the identifiable assets acquired, the liabilities assumed, and any controlling interest; recognizes and measures the goodwill acquired in the business combination or a gain from a bargain purchase; and determines what information to disclose to enable users of the financial statements to evaluate the nature and financial effects of the business combination. FAS 141(R) is to be applied prospectively to business combinations for which the acquisition date is on or after an entity’s fiscal year that begins after December 15, 2008. The Company will assess the impact of SFAS 141(R) if and when a future acquisition occurs.

6. SHAREHOLDERS’ EQUITY AND SHARE-BASED COMPENSATION

Preferred Stock

The Company has authorized 5,000,000 shares of preferred stock, no par value, of which none were issued or outstanding at December 31, 2007. The preferred stock may be issued from time to time in one or more series. The Board of Directors is authorized to determine or alter the rights, preferences, privileges and restrictions of such preferred stock.

Stock Repurchase Plan

In November 2006, the Company's Board of Directors approved a $50 million share repurchase program for calendar year 2007.  On November 13, 2007, the Board of Directors of Micrel approved a modification to the plan to increase the aggregate amount authorized to be used to repurchase shares in calendar year 2007 to $65,000,000.  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, and 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, employee stock purchase plan and 401(k) plan.  The timing and amount of any repurchase of shares will be determined by the Company’s management, based on its evaluation of market conditions and other factors. During the year ended December 31, 2007, the Company repurchased 5,515,854 shares of its common stock for $55.1 million.

Share repurchases are recorded as a reduction of common stock to the extent available. Any amounts repurchased in excess of common stock are recorded as a reduction of retained earnings.

On October 22, 2007, the Company's Board of Directors approved a $50 million share repurchase program for calendar year 2008.  Repurchases may occur from time to time in the open market or in privately negotiated transactions through December 31, 2008.

Incentive Award Plans

Under the Company's 2003 Incentive Award Plan (the “2003 Plan”), 1994 Stock Option Plan and its 2000 Non-Qualified Stock Incentive Plan, 39,958,672 shares of Common Stock are authorized for issuance to employees. The 1994 Stock Option Plan and 2000 Non-Qualified Stock Incentive Plan provide that, for stock options, the option price will be determined by the Board of Directors at a price not less than the fair value as represented by the closing price of the Company's Common Stock on the last trading day before the date of grant.  The 2003 Incentive Award Plan provides that, for stock options, the option price will be determined by the Board of Directors at a price not less than the fair value as represented by the closing price of the Company's Common Stock on the date of grant.  Certain shareholder/employees of the Company are granted options at 110% of the current fair market value. Options granted under the 2000 Non-Qualified Stock Incentive Plan are exercisable in 20% increments with the initial 20% vesting occurring six months after the date of grant and then in annual increments of 20% per year from the date of grant. The Company is not currently awarding option grants under the 2000 Non-Qualified Stock Incentive Plan. Options granted under the 2003 Incentive Award Plan and 1994 Stock Option Plan typically become exercisable in not less than cumulative annual increments of 20% per year from the date of grant. The term of each stock option is no more than ten years from the date of grant. At December 31, 2007, 14,536,314 total shares were reserved for future issuance, of which 2,523,270 shares were available for future grants under the Option Plans.

As of December 31, 2007, the aggregate pre-tax intrinsic value (which is the amount by which the closing price of the Company's common stock at December 31, 2007 exceeded the exercise price of the options) of options outstanding and options exercisable was approximately $946,000 and $913,000, respectively. As of December 31, 2007, the estimated number of options exercisable and expected to vest was 10.9 million shares with a weighted average remaining contractual life of 5 years and estimated aggregate intrinsic value of $937,000.

The 2003 Plan also provides for the use of incentive awards other than stock options.  In October 2007, the Company’s Compensation Committee approved a plan to begin granting Restricted Stock Units ("RSU"s) to employees in accordance with the provisions of the 2003 Plan.  As of December 31, 2007 there were no RSUs granted.

Accounting for Share-based Compensation

Under SFAS No. 123R, share-based compensation costs for stock option grants are based on the fair value calculated from a stock option pricing model on the date of grant. The Company has utilized the Black-Scholes option pricing model to determine the fair value for stock option grants.  The fair value of stock option grants issued from January 1, 2006 onwards are recognized as compensation expense on a straight-line basis over the vesting period of the grants. Compensation expense recognized is shown in the operating activities section of the consolidated statements of cash flows.

Prior to adopting SFAS No. 123R, the Company accounted for stock option grants under the recognition and measurement provisions of APB 25. Compensation cost related to stock options granted at fair value under those plans was not recognized in the consolidated statements of operations. Compensation cost related to stock options granted below the fair market value on the grant date was recognized in the consolidated statements of operations. In addition, prior to adopting SFAS No. 123R, the Company presented all tax benefits of deductions resulting from the exercise of stock grants as operating cash flows in the consolidated statements of cash flows. SFAS No. 123R requires the cash flows resulting from the tax benefits from tax deductions in excess of the compensation cost recognized (excess tax benefits) to be classified as financing cash flows.

The fair value of the Company’s stock options granted under the Option Plans was estimated at the date of grant using the Black-Scholes option pricing model with the following weighted-average assumptions:

	Years Ended December 31,
	2007		2006		2005
Expected life (years)		6.0		5.5		5.0
Stock volatility		51.4%		58.7%		76.9%
Risk free interest rates		4.4%		4.9%		4.1%
Dividends during expected terms		0.9%	none		none

Expected term is based on an analysis of historical exercises and the remaining contractual life of options. The calculation of expected term for previous SFAS No. 123 disclosure fair value estimates was based solely on an analysis of historical exercises of stock options. The Company believes that an analysis of historical exercises and remaining contractual life of options provides a better estimate of future exercise patterns.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

Years Ended December 31, 2007, 2006 and 2005

Stock volatility is based upon a combination of both historical stock price volatility and implied volatility derived from traded options on the Company’s stock in the marketplace.  The calculation of expected volatility for previous SFAS No. 123 fair value disclosure estimates was based solely on historical stock price volatility. The Company believes that the combination of historical volatility and implied volatility provides a better estimate of future stock price volatility.

The Company continues to base the estimate of risk-free rate on the U.S. Treasury yield curve in effect at the time of grant.

As part of the requirements of SFAS No. 123R, the Company is required to estimate potential forfeitures of stock grants and adjust compensation cost recorded accordingly. The estimate of forfeitures will be adjusted over the requisite service period to the extent that actual forfeitures differ, or are expected to differ, from such estimates. Changes in estimated forfeitures will be recognized through a cumulative catch-up adjustment in the period of change and will also impact the amount of stock compensation expense to be recognized in future periods.

The following table shows total share-based compensation expense recognized in the Consolidated Statement of Operations for 2007 and 2006, pursuant to SFAS No. 123R and for 2005 pursuant to APB 25 (in thousands):

	Years Ended December 31,

Less income tax effect		920		819		296
Net share-based compensation expense	$	4,565	$	7,596	$	474

Total share-based compensation cost capitalized as part of inventory as of December 31, 2007 and 2006 was $122,000 and $225,000, respectively. At December 31, 2007, there was $17.1 million of total unrecognized compensation cost related to non-vested stock option awards which is expected to be recognized over a weighted-average period of 3.6 years.

Beginning in 1996, the Company began to follow a practice of granting employee stock options on the date with the lowest closing price within the thirty-day period subsequent to the employee’s date of hire (the "Thirty-Day Method").  The Company continued to utilize this method for the majority of grants, both for new hires and for replenishment grants to existing employees, until December 20, 2001.  At that time, the Company determined that options granted using the Thirty-Day Method were compensatory under APB No 25, and discontinued use of the Thirty-Day Method thereafter. For financial reporting purposes, per APB No 25, the measurement date for determining compensation cost in stock option plans is the first date on which are known both (1) the number of shares that an individual is entitled to receive and (2) the option purchase price.  Compensation cost is calculated for any difference between the option exercise price and the fair market value on the measurement date. When applying APB 25 to the Thirty-Day Method described above, the measurement date was the thirtieth day following a new-hire's commencement of employment, when the lowest price (the exercise price) within the first thirty days following employment commencement was known. Compensation expense related to options granted under the Thirty-Day

MICREL, INCORPORATED

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

Years Ended December 31, 2007, 2006 and 2005

Method was calculated based on the price difference between the exercise price and the closing price on the thirtieth day following a new-hire's commencement of employment multiplied by the number of options granted and recognized as expense over the vesting period (generally five years). The Company continued to recognize stock compensation expense through 2005 for amortization of options granted under the Thirty-Day method in 2001 and earlier.

In addition to the stock options granted using the Thirty-Day Method, Micrel assumed certain stock options granted to employees of Kendin Communications in connection with the acquisition of Kendin Communications in the second quarter of 2001.  Because the fair market value of the shares subject to those options assumed in the Kendin acquisition exceeded their exercise prices as of the date Micrel assumed them, the Company recorded deferred stock compensation expense for the unvested portion of the assumed options.

Deferred stock compensation expense balances were recorded as a contra-equity amount and then amortized as a charge to operating results over the applicable vesting periods.  As of December 31, 2005 total unamortized stock compensation related to the Thirty-Day Method and the Kendin Communication acquisition noted above was $294,000. Upon the adoption of SFAS No. 123R on January 1, 2006, the unamortized APB 25 stock compensation was reversed with a corresponding reduction to common stock.

Pro Forma Information under SFAS No. 123 for Periods Prior to SFAS No. 123R Adoption - As discussed above, results for prior periods have not been restated to reflect the effects of implementing SFAS No. 123R. The following table illustrates the effect on net income and earnings per share if the Company had applied the fair value recognition provisions of SFAS No. 123 to stock options granted under the Company’s stock option plans and shares issued under the employee stock purchase plan for the year ended December 31, 2005. For purposes of this pro forma disclosure, the value of the stock options was estimated using a Black-Scholes option-pricing model, amortization computed using the graded vesting method and forfeitures accounted for as they occurred:

Employee Stock Purchase Plan

Under the Company’s 1994 Employee Stock Purchase Plan (the “1994 ESPP”), as amended and restated as of January 1, 1996, eligible employees were permitted to have salary withholdings to purchase shares of Common Stock at a price equal to 85% of the lower of the market value of the stock at the beginning or end of each six-month offer period, subject to an annual limitation. Shares of Common Stock issued under the Purchase Plan were 202,325 in 2005 at a weighted average price of $9.42. At December 31, 2005, there were 2,278,346 shares of Common Stock issued under the 1994 Employee Stock Purchase Plan. The 1994 ESPP terminated on January 1, 2006.

In May, 2006 the Company's shareholders approved a new Employee Stock Purchase Plan (the “2006 ESPP”).  Under the terms of the 2006 ESPP, eligible employees are permitted to have salary withholdings to purchase shares of Common Stock at a price equal to 95% of the market value of the stock at the end of each three-month offer period, subject to an annual limitation. The aggregate number of shares of common stock which may be issued under the plan shall be no more than 2,000,000 shares. Stock issued under the Purchase Plan during 2007 and 2006 was 27,482 and 14,916, respectively, shares of Common Stock at weighted average prices of $10.02 and $9.61, respectively. The 2006 ESPP is considered non-compensatory under SFAS No. 123R.

Cancellation of Shares Held in Escrow

In July 2006, 400,050 shares of the Company’s Common Stock which were held in an escrow account pursuant to a contract dispute, were returned to the Company and cancelled.

7. INCOME TAXES

The income tax provisions for the years ended December 31, 2007, 2006 and 2005, as a percentage of income before taxes, were 36%, 39% and 32%, respectively.  The income tax provision for such 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.  A reconciliation of the statutory federal income tax rate to the effective tax rate for the years ended December 31 is as follows:

	2007		2006		2005
Statutory federal income tax rate		35%		35%		35%

Pre-tax income from non-U.S. jurisdictions was not material in all periods presented.

Deferred tax assets and liabilities result primarily from temporary differences between book and tax bases of assets and liabilities, state and federal research and development credit carryforwards and state manufacturers credit carryforwards.  The Company had net current deferred tax assets of $19.4 million and net long-term deferred tax assets of $9.3 million as of December 31, 2007.  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.

Included in net deferred assets are net operating loss and credit carryforwards. Due to the Company's acquisition of Synergy in 1998, the Company has available pre-ownership change federal net operating loss carryforwards of approximately $5.4 million which will expire in the years 2008 through 2014 if not utilized. Under Section 382 of the Internal Revenue Code, these pre-ownership change net operating loss carryforwards are subject to an annual limitation. The Company believes that it is more likely than not that these net operating loss carryforwards will be utilized before expiration. In addition, the Company has available state credit carryforwards of approximately $15.5 million consisting of research credit carryforwards, of which approximately $2.3 million represents pre-ownership change carryforwards subject to the Section 382 annual limitation. The state research credit carryforwards are not subject to expiration and may be carried forward indefinitely until utilized.

Effective January 1, 2007, the Company adopted the provisions of FIN No. 48. The adoption of FIN No. 48 did not result in a cumulative effect adjustment to retained earnings as of January 1, 2007. Consistent with the provisions of FIN No. 48, the Company reclassified $4.4 million of current income tax liabilities as follows: $1.9 million increase to non-current income taxes payable and $2.5 million decrease to non-current deferred tax assets. Upon adoption, the gross liability for income taxes associated with uncertain tax positions at January 1, 2007 was $6.6 million. This gross liability can be reduced by $2.2 million of offsetting tax benefits primarily associated with the federal effects of potential state income tax uncertainties.

As of December 31, 2007, the gross liability for uncertain tax positions was $8.0 million and the net liability, reduced for the federal effects of potential state tax exposures, was $5.4 million. If these uncertain tax positions are sustained upon tax authority audit, or otherwise become certain, the net $5.4 million would favorably affect the Company’s tax provision in such future periods.  Included in the $5.4 million is $2.6 million which has not yet reduced income tax payments, and, therefore, has been netted against non-current deferred tax assets.  The remaining $2.8 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.

A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows (in thousands):

Balance at January 1, 2007	$	4,352
Additions based on tax positions related to the current year		980
Additions for accrued interest for tax positions of prior years		111
Balance at December 31, 2007	$	5,443

The Company continues to recognize interest and penalties related to income tax matters as part of the income tax provision. As of January 1, 2007 and December 31, 2007, the Company had $140,000 and $251,000, 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.

8. COMMITMENTS AND CONTINGENCIES

Lease Agreements

The Company leases some of its facilities and equipment under operating lease agreements that expire in the years 2008 through 2013. Some of the facility lease agreements provide for escalating rental payments over the lease periods. Rent expense is recognized on a straight-line basis over the term of the lease. Deferred rent represents the difference between rental payments and rent expense recognized on a straight-line basis.

Future minimum payments under these agreements are as follows (in thousands):

Year Ending December 31,
2008	$	1,911
2009		1,496
2010		1,348
2011		478
2012		93
Thereafter		15
	$	5,341

Rent expense under operating leases for the years ended December 31, 2007, 2006, and 2005 was $1.8 million, $1.9 million and $1.4 million, respectively.

Open Purchase Orders

As of December 31, 2007, the Company had approximately $13.7 million in open purchase orders. 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. These obligations primarily relate to future purchases of wafer fabrication raw materials, foundry wafers, assembly and testing services and manufacturing equipment. The amounts are based on the Company's contractual commitments.

Letters of Credit

Micrel's borrowing arrangements (see Note 5) include a provision for the issuance of commercial or standby letters of credit by the bank on behalf of the Company. At December 31, 2007 there was $525,000 in standby letters of credit outstanding. The letters of credit are issued to guarantee payments for the Company's workers compensation program.

Indemnification Obligations

Micrel is a party to a variety of contractual relationships pursuant under which it may be obligated to indemnify the other party with respect to certain matters. Typically, these obligations arise in the context of contracts entered into by Micrel, or regular sales and purchasing activities, under which Micrel may agree to hold the other party harmless against losses arising from claims related to such matters as title to assets sold, certain intellectual property rights, specified environmental matters, certain income taxes, etc.  In these circumstances, indemnification by Micrel is customarily conditioned on the other party making a claim pursuant to the procedures specified in the particular contract or in Micrel’s standard terms and conditions, which procedures may allow Micrel to challenge the other party's claims, or afford Micrel the right to settle such claims in its sole discretion.  Further, Micrel's obligations under these agreements may be limited in terms of time and/or amount, and in some instances, Micrel may have recourse against third parties for certain payments made by it under these agreements.

It is not possible to predict the maximum potential amount of future payments or indemnification costs under these or similar agreements due to the conditional nature of Micrel's obligations and the unique facts and circumstances involved in each particular agreement. Historically, payments made by Micrel under these agreements have not had a material effect on its business, financial condition, cash flows, or results of operations. Micrel believes that if it were to incur a loss in any of these matters, such loss would not have a material effect on its business, financial condition, cash flows or results of operations.

9. PROFIT-SHARING 401(k) PLAN

The Company has a profit-sharing and deferred compensation plan (the “Plan”). All employees completing one month of service are eligible to participate in the Plan. Participants may contribute 1% to 15% of their annual compensation on a before tax basis, subject to Internal Revenue Service limitations. Profit-sharing contributions by the Company are determined at the discretion of the Board of Directors. The Company accrued $750,271 in contributions for the year ended December 31, 2007 and made $725,000 and $622,000 in contributions to the Plan for the years ended December 31, 2006 and 2005, respectively. Participants vest in Company contributions ratably over six years of service.

10. LITIGATION

On May 9, 1994, Linear Technology Corporation (“LTC”), a competitor of the Company, filed a complaint against the Company, entitled Linear Technology Corporation v. Micrel, Incorporated, in the United States District Court in San Jose, California, alleging patent and copyright infringement and unfair competition.  After many years of motions and appeals, a bench trial on the merits was commenced on November 30, 2005, and concluded on December 16, 2005.  The parties filed post-trial briefs on January 20, 2006. On June 9, 2006, the Court ruled that Micrel had willfully infringed the patent-in-suit, and awarded damages to LTC.  As a result of this judgment, the Company recorded $846,000 in other operating expense in the Company’s 2006 financial statements. This accrued liability was paid in 2006.

On February 26, 1999, the Lemelson Medical, Education & Research Foundation (the “Lemelson Partnership”) filed a complaint which was served on the Company on June 15, 1999, entitled Lemelson Medical, Education & Research Foundation, Limited Partnership v. Lucent Technologies Inc., et al. in the United States District Court in Phoenix, Arizona, against eighty-eight defendants, including the Company, alleging infringement of a number of Lemelson Foundation patents.  The complaint in the lawsuit sought unspecified compensatory damages, treble damages and attorneys' fees, as well as injunctive relief against further infringement of the Lemelson patents at issue.  In defense of this action, the Company was part of a Joint Defense Group consisting of a number of companies who were opposing the lawsuit together (the "Joint Defense Group").  On January 17, 2007, the parties entered into an agreement to settle the litigation for payment of a mutually agreeable sum, as a result of which, the four companies in the Joint Defense Group have acquired a package license under the Lemelson patents. During the fourth quarter of 2006, Micrel accrued $120,000 to other operating expense for the Company's portion of the liability under this settlement agreement.  This amount was paid during the first quarter of 2007.

On December 27, 2002, the Company filed a complaint against TRW, Inc. (“TRW”) entitled Micrel, Incorporated v. TRW, Inc., dba TRW Automotive Electronics Group, in the United States District Court, Northern District of Ohio, Eastern Division, alleging various causes of action relating to breach of a relationship surrounding the development of certain custom products by Micrel for TRW.  In this lawsuit, Micrel alleged that TRW breached various agreements to assist in Micrel’s development of, and to purchase, certain Application Specific Integrated Circuits.  The complaint sought compensatory damages, attorneys’ fees and costs associated with the suit.  On February 24, 2003, TRW filed an answer to the Company’s complaint and a counterclaim alleging various causes of action relating to breach of the above-mentioned relationship concerning ASIC development.  On July 22, 2005, a jury ruled against the Company and in favor of TRW in its counterclaim against Micrel.  The outcome of the jury trial was a judgment on July 26, 2005, awarding damages for the benefit of TRW in the amount of $9.3 million.  The damages amount was accrued in other current liabilities in the Company’s second quarter 2005 financial statements.  On January 13, 2006, the Company filed a notice of its intent to appeal the jury’s verdict.  On February 23, 2006, the Company posted a surety bond in the amount of $10.5 million in the United States District Court, Northern District of Ohio, to stay payment of damages and potential interest awarded to TRW (see Note 1).  On April 24, 2007, a hearing was held in the United States Court of Appeals for the Sixth Circuit, at which time the Court heard oral argument on the Appeal.  On May 4, 2007, the Court of Appeals issued its ruling affirming the jury’s verdict.  During the quarter ended June 30, 2007, the Company paid TRW the legal judgment for total damages and interest in the amount of $10.2 million.

On April 21, 2003, the Company filed a complaint against its former independent public accountants Deloitte & Touche LLP (“Deloitte”) entitled Micrel, Incorporated v. Deloitte & Touche LLP in the Superior Court of the State of California, County of Santa Clara, alleging various causes of action relating to certain professional advice received by Micrel from Deloitte.  In this lawsuit, Micrel alleged that Deloitte negligently rendered services as accountants to Micrel, breached certain agreements with Micrel by failing to perform services using ordinary skill and competence and in conformance with generally accepted principles for such work and made certain false representations upon which Micrel justifiably relied.  Deloitte denied all allegations in the complaint.  The complaint sought compensatory damages, costs associated with the suit and such other relief that the court may deem just and proper.  On February 23, 2007, the parties entered into a Settlement Agreement and Mutual Releases. Under the terms of the Agreement, the parties agreed to dismiss with prejudice the pending litigation and Deloitte paid to Micrel a settlement amount of $15.5 million. The Company recorded the $15.5 million settlement amount, in the quarter ended March 31, 2007, as other non-operating income as the settlement payment did not represent, either directly or indirectly, income earned from the Company’s operations, nor did it represent reimbursement of operating expenses incurred.

On November 11, 2004, the Company filed a complaint against Monolithic Power Systems (“MPS”), entitled Micrel, Inc. v. Monolithic Power Systems, in the United States District Court, Northern District of California alleging two causes of action for infringement by MPS of certain patents owned by Micrel.  In the complaint, the Company alleged that MPS had been and was infringing U.S. patent no. 5,517,046 (the “’046 patent”) and U.S. patent no. 5,556,796 (the “’796 patent”).    Subsequently, on November 29, 2004, the Company filed an amended complaint adding Michael R. Hsing, MPS’ President and Chief Executive Officer (“Hsing”), and James C. Moyer, MPS’ Chief Design Engineer (“Moyer”) as defendants.  Hsing and Moyer are both former employees of Micrel.  In addition to the original two causes of action against MPS for infringement of the '046 and '796 Patents, the amended complaint added causes of action for statutory and common law misappropriation of Micrel’s trade secrets, breach of confidentiality agreements by Hsing and Moyer, and violation of California’s Unfair Competition Law.  On September 21, 2006, the Company and MPS entered into a Settlement Agreement, agreeing to dismiss all claims and counterclaims in the litigation with prejudice.  Micrel also agreed to release MPS, Hsing and Moyer from all claims for any alleged trade secret claims based on any confidential information. In addition, Micrel licensed U.S. Patent Nos. 5,517,046 and 5,556,796 to MPS. Under the terms of the agreement MPS agreed to pay a license fee of $3.0 million of which $1.0 million was paid in September 2006, $1.0 million was paid in December 2006 and the remaining $1.0 million balance was paid in January 2008.  In the third quarter of 2006 the Company recorded $2.9 million in net revenues representing the present value of the license payments from MPS.

On June 9, 2006, Deerfield 3250 Scott, LLC ("Deerfield"), the building owner of Micrel's Santa Clara Wafer Fab facility which was closed in 2003 (see Note 12), filed a complaint against the Company entitled "Deerfield 3250 Scott, LLC vs. Micrel, Inc. et al" in the Superior Court of the State of California, County of Santa Clara.  In February 2006, Micrel terminated this building lease under the terms of the lease agreement due to major vandalism rendering the building unusable.  Deerfield disputes that Micrel had a right to terminate, alleging that the vandalism took place because of the negligence of Micrel and that Micrel should not be able to benefit from its own negligence.  The complaint seeks damages in an unspecified amount for rent through the remaining term of the lease (from March 1 through October 31, 2006), alleged damages to the premises, and for wrongful removal of equipment.  Micrel disputes Deerfield's allegations and will vigorously defend against the action.  On July 21, 2006, Micrel answered the complaint with a denial of any liability

and the filing of a cross-complaint against Deerfield seeking return of the security deposit and rent paid from the date of the casualty, January 20, 2006 through February 28, 2006.  The case is in the discovery and pre-trial phase and a trial date has been set for May 19, 2008.

With the exception of the previously recorded operating expenses, the Company believes that the ultimate outcome of the legal actions discussed will not result in a material adverse effect on the Company's financial condition, results of operation or cash flows, and the Company believes it is not reasonably possible that a material loss has been incurred.  However, litigation is subject to inherent uncertainties, and no assurance can be given that the Company will prevail in these lawsuits.  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.

Certain additional 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.

11.           SEGMENT REPORTING

The Company follows the provisions of SFAS No. 131, Disclosures about Segments of an Enterprise and Related Information. SFAS No. 131 establishes standards for reporting information regarding operating segments in annual financial statements and requires selected information for those segments to be presented in interim financial reports issued to stockholders. SFAS No. 131 also establishes standards for related disclosures about products and services and geographic areas. 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 product revenues, which consist primarily of custom and foundry products revenues 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 practical to show assets by reportable segments.

Net Revenues by Segment (in thousands):	Years Ended December 31,
	2007		2006		2005
Standard Products	$	237,356	$	258,214	$	239,177
Other Products		20,618		18,093		11,179
Total net revenues	$	257,974	$	276,307	$	250,356

For the year ended December 31, 2007 two world-wide distributors accounted for $38.7 million (15%) and $33.1 million (13%), respectively, of the Company's net revenues. For the year ended December 31, 2006 three customers, consisting of two world-wide distributors and an Asian based stocking representative, accounted for $41.3 million (13%), $34.2 million (12%) and $28.0 million (10%), respectively, of the Company's net revenues. For the year ended December 31, 2005 three customers, consisting of an original equipment manufacturer, an Asian based stocking representative and a world-wide distributor, accounted for $34.9 million (14%), $29.5 million (12%) and $29.5 million (12%), respectively, of the Company's net revenues.  These significant customers for 2007, 2006 and 2005 primarily purchased the Company's standard products.

12.           RESTRUCTURING AND MANUFACTURING FACILITY IMPAIRMENT

In September 2002, the Company approved a plan to close its Santa Clara, California wafer fabrication facility to reduce costs and improve operating efficiencies.  The Company accrued $5.5 million in restructuring expenses associated with the facility closure which consisted of $1.0 million for equipment disposal costs and $4.5 million in net contractual building lease costs, excluding estimated sublease income, that will provide no future benefit.  During July 2003, the Company ceased all manufacturing processes within the Santa Clara facility and completed the relocation of all employees to its San Jose, California facilities. During 2004, the Company increased its accrued restructuring expenses for contractual building lease costs by $584,000 to eliminate remaining estimated future sub-lease income as efforts to sub-lease the facility were unsuccessful. In February 2006, the Company terminated the lease under the terms of the lease agreement due to major vandalism rendering the building unusable.  The Lessor is disputing the termination of the lease (see Note 10).  Although the Company is no longer making payments to the Lessor, the restructuring costs shown above represent the estimated potential amount owed under the lease prior to termination.  Other disposal costs include estimated costs associated with the final closing of the facility.

Balance December 31, 2007	$	1,470		$	317		$	1,787

During 2007, the Company accrued $128,000 in interest expense on unpaid facility rent and reclassified $85,000 from non-current deferred rent into accrued restructuring.

All of the $1.8 million in accrued restructuring costs has been included within other current liabilities as of December 31, 2007.  Actual future costs may be different than these estimates and could require an adjustment to the restructuring accrual in the period such determination is made.

13.           PATENT LICENSE AGREEMENT

In September 2006, Micrel entered into a Patent License Agreement with International Business Machines Corporation ("IBM").  Under the Agreement, each party licensed to the other all patents issued or issuing on patent applications entitled to an effective filing date prior to January 1, 2012.  Certain IBM patents are not licensed to Micrel owing to IBM’s arrangements with third parties.  In consideration for the license to IBM’s patents, Micrel paid IBM $2,050,000.

Based on the estimated historical and future benefits of the Patent License Agreement, the Company has allocated the payment as follows (in thousands):

Settlement of patent disputes	$	714
Patent license		1,336
Total payment	$	2,050

To determine the amounts to be apportioned to settlement of patent disputes and to patent license, the Company apportioned the payment based on the ratio of estimated risk adjusted pre-settlement revenues for products that may have utilized certain IBM patents to the present value of estimated future revenues from products that are expected to utilize one or more of the IBM patents under the Patent License Agreement. The $714,000 valuation of the settlement of patent disputes was expensed to cost of revenues in the third quarter of 2006. The patent license valuation of $1.3 million was recorded as an intangible asset and is being amortized to cost of revenues on a straight-line basis over its estimated useful life of 5.25 years.

At December 31, 2007, the Company held $16.6 million in long-term investments. Long-term investments consisted of senior auction rate notes secured by student loans. In February 2008, some of these auction rate securities failed to auction successfully due to sell orders exceeding buy orders (see the discussion of investments included in Note 1).
