Overview

We are a designer, developer and global supplier of a broad portfolio of power semiconductors. Our portfolio of power semiconductors includes over 1,400 products, and has grown significantly with the introduction of over 150 new products during the fiscal year 2014, and over 195 and 240 new products in the fiscal years 2013 and 2012, respectively. Our teams of scientists and engineers have developed extensive intellectual properties and technical knowledge that encompass major aspects of power semiconductors, which we believe enables us to introduce and develop innovative products to address the increasingly complex power requirements of advanced electronics. We have an extensive patent portfolio that consists of 420 patents and 213 patent applications in the United States as of June 30, 2014. We differentiate ourselves by integrating our expertise in technology, design, manufacturing capability and advanced packaging to optimize product performance and cost. Our portfolio of products targets high-volume applications, including personal computers, flat panel TVs, LED lighting, smart phones, battery packs, consumer and industrial motor controls and power supplies for TVs, computers, servers and telecommunications equipment.

During the fiscal year ended June 30, 2014, we continued our diversification program by developing new silicon and packaging platforms to expand our serviceable available market, or SAM and offer higher performance products. Our metal-oxide-semiconductor field-effect transistors, or MOSFET, portfolio expanded significantly across a full range of voltage applications. We also developed new technologies and products designed to penetrate into markets beyond our MOSFET computing base, including the consumer, communications and industrial markets as well as power IC for the next generation computing applications.

Our business model leverages global resources, including research and development and manufacturing in the United States and Asia. Our sales and technical support teams are localized in several growing markets primarily in Asia. We operate a 200mm wafer fabrication facility located in Hillsboro, Oregon, or the Oregon fab, which enables us to accelerate proprietary technology development, new product introduction and improve our financial performance. To meet the market demand for the more mature high volume products, we also utilize the wafer manufacturing capacity of selected third party foundries. For assembly and test, we primarily rely upon our in-house facilities in China. In addition, we utilize subcontracting partners for industry standard packages. We believe our in-house packaging and testing capability provides us with a competitive advantage in proprietary packaging technology, product quality, costs and sales cycle time.
We were incorporated in Bermuda on September 27, 2000 as an exempted limited liability company. The address of our registered office is Clarendon House, 2 Church Street, Hamilton HM 11, Bermuda. Our agent for service of process in the U.S. for the purpose of our securities filings is our Chief Executive Officer, Mike F. Chang, c/o Alpha and Omega Semiconductor Incorporated, 475 Oakmead Parkway, Sunnyvale, CA 94085. Telephone number of our agent is (408) 830-9742.

We have incorporated various wholly-owned subsidiaries in different jurisdictions. Please refer to Exhibit 21.1 for a complete list of our subsidiaries.
Our industry

Semiconductors are electronic devices that perform a variety of functions, such as converting or controlling signals, processing data and delivering or managing power. With advances in semiconductor technology, the functionality and performance of semiconductors have generally increased over time, while size and cost have generally decreased. These advances have led to a proliferation of more complex semiconductors being used in a wide variety of consumer, computing, communications and industrial markets and have contributed to the growth of the semiconductor industry.
Analog semiconductors

The semiconductor industry is segmented into analog and digital. Analog semiconductors process light, sound, motion, radio waves and electrical currents and voltages. In contrast, digital semiconductors process binary signals represented by a sequence of ones and zeros.

As a result of these fundamental differences, the analog semiconductor industry is distinct from the digital semiconductor industry in terms of the complexity of design and the length of product cycle. Improper interactions between analog circuit elements can potentially render an electronic system inoperable. Experienced engineers engaged in the design process are necessary because computer-aided design cannot fully model the behavior of analog circuitry. Therefore, experienced analog engineers with requisite knowledge are in great demand but short supply worldwide. In addition, analog semiconductors tend to have a longer product life cycle because original design manufacturers, or ODMs and original equipment manufacturers, or OEMs typically design the analog portions of a system to span multiple generations of their products. Once designed into an application, the analog portion is rarely modified because even a slight change to the analog portion can cause unexpected interactions with other components, resulting in system instability.
Power semiconductors

Power semiconductors are a subset of the analog semiconductor sector with their own set of characteristics unique to power architecture and function. Power semiconductors transfer, manage and switch electricity to deliver the appropriate amount of voltage or current to a broad range of electronic systems and also protect electronic systems from damage resulting from excessive or inadvertent electrical charges.

Power semiconductors can be either discrete devices, which typically comprise only a few transistors or diodes, or ICs, which incorporate a greater number of transistors.  The function of power discretes is power delivery by switching, transferring or converting electricity.  Power transistors comprise the largest segment of the power discretes market. Power ICs, sometimes referred to as power management ICs, perform power delivery and power management functions, such as controlling and regulating voltage and current and controlling power discretes.

The growth of the power semiconductor market in recent years has several key drivers. The proliferation of computer and consumer electronics, such as desktop computers, notebooks, tablets, smart phones, flat panel displays and portable media players created the need for sophisticated power management to improve power efficiency and extend battery life. The evolution of these products is characterized by increased functionality, thinner or smaller form factors and decreasing prices. Our Power IC and low voltage (5V-40V) MOSFET products address this market. In the area of AC-DC power supplies for electronic equipment, data centers and servers, the market is characterized by a continuous demand for energy conservation through higher efficiency, which is driving the need for our medium voltage (40V-400V) and high voltage (500V-1000V) MOSFET products. The increased application of power semiconductors to control motors in white goods and industrial applications, is driving demand for Insulated Gate Bipolar Transistors, or IGBTs. IGBTs are also being used in renewable energy and automotive applications.

The evolution toward smaller form factors and complex power requirements in the low voltage areas has driven further integration in power semiconductors, resulting in power ICs that incorporate the functionalities of both power management and power delivery functions in a single device. Power ICs can be implemented by incorporating all necessary power functions either on one piece of silicon or multiple silicon chips encapsulated into a single device. Additionally, the advancement in semiconductor packaging technology enables increased power density and shrinking form factors.

Power semiconductor suppliers develop and manufacture their products using various approaches which tend to fall across a wide spectrum of balancing cost savings with proprietary technology advantages. At one end of the spectrum are integrated design manufacturers, or IDMs, which own and operate the equipment used in the manufacturing process and design and manufacture products at their in-house facilities. IDMs exercise full control over the implementation of process technologies and have maximum flexibility in setting priorities for their production and delivery schedules. At the other end of the spectrum are completely-outsourced fabless semiconductor companies, which rely entirely on off-the-shelf technologies and processes provided by their manufacturing partners. These companies seek to reduce or eliminate fixed costs by outsourcing both product manufacturing and development of process technologies to third parties. The “fab-lite” model seeks to achieve the best balance between technological advancement and cost effectiveness by using a dedicated in-house technology laboratory to drive rapid new product developments, while utilizing third-party foundry capacity for mature products. This is particularly important in the development of power semiconductor products due to the unique nature of their technology. While digital technologies are highly standardized in leading foundries, power semiconductor technologies tend to be more unique as they seek to accommodate a wider range of voltage applications. Accordingly, third-party foundries, which are primarily setup for digital technologies, can be limited when it comes to the development of new power semiconductor technologies.
Our strategies

Our strategy is to advance our position as a designer, developer and global supplier of a broad portfolio of power semiconductors utilizing a fab-lite business model.

The fab-lite business model allows us to accelerate the development of our proprietary technology at our Oregon fab, to bring new products to market faster, and improve our financial performance in the long run. We also expect this “fab-lite” model to provide quicker response to our customer demands, enhance relationships with strategic customers, provide flexibility in capacity management and geographic diversification of our wafer supply chain. This approach allows us to retain a higher level of control over the development and application of our proprietary process technology, thereby reducing certain operational risks and costs associated with utilizing third-party foundries.

In recent years, the PC market has experienced a significant global decline primarily due to continued growth of demand in tablets and smart phones. Because a significant portion of our revenue was dependent upon the PC market, such decline resulted in lower utilization of our Oregon fab and packaging facilities in China. The lower utilization had significant negative impact on our financial performance, especially gross margins. In response to this trend, we have been and are continuing to execute our strategies to diversify our product portfolio and penetrate into other market segments, including the consumer, communications and industrial markets, which we believe we would mitigate and eventually overcome the reduced demand from the declining PC markets. Although we will gradually reduce our reliance on the computing market, we are also committed to continue to support our computing business and capitalize on the opportunity with a more focused PC product strategy.

The Oregon fab represents a strategic acquisition that has enabled us to accelerate our new technology and product development. During fiscal year of 2014, we introduced over 140 medium and high voltage MOSFET, IGBT products, targeting the consumer, communication and industrial markets, as well as low voltage MOSFET products for the computing market.

We plan to further expand the breadth of our product portfolio to increase our total bill-of-materials within an electronic system and to address the power requirements of additional electronic systems. Our product portfolio currently consists of over 1,400 products and we have introduced over 150 new products in this past fiscal year. We will continue to leverage our power expertise to further increase our product lines, including higher performance power ICs, IGBTs and high and medium voltage MOSFETs, in order to expand our addressable market and improve our margin profile. We also believe that our expanding product offerings will allow us to penetrate new end-market applications and provide us with an important competitive advantage. OEMs and ODMs generally prefer to limit their supplier base to a smaller set of vendors capable of providing a comprehensive menu of products across multiple electronic platforms.
Leverage our power semiconductor expertise to drive new technology platforms

We believe that the ever-increasing demand for power efficiency in power semiconductors requires expertise in and a deep understanding of the interrelationship among device physics, process technologies, design and packaging. We also believe that engineers with experience and understanding of these multiple disciplines are in great demand but short supply. Within this context, we believe that we are well positioned to be a leader in providing total power management solutions due to our extensive pool of experienced scientists and engineers and our strong IP portfolio. Accordingly, we intend to leverage our

3


expertise to increase the number of power discrete technology platforms and power IC designs to expand our product offerings and deliver complete power solutions for our targeted applications.
Increase direct relationships and product penetration with OEM and ODM customers

We have developed direct relationships with key OEMs who are responsible for branding, designing and marketing a broad array of electronic products, as well as ODMs who have traditionally been responsible for manufacturing these products. While OEMs typically focus their design efforts on their flagship products, as the industry has evolved, ODMs are increasingly responsible for designing portions, or entire systems, of the products they manufacture for the OEMs. In addition, several ODMs are beginning to design, manufacture and brand their own proprietary products which they sell directly to consumers. We intend to strengthen our existing relationships and form new ones with both OEMs and ODMs by aligning our product development efforts with their product requirements, increasing the number of our products used within their systems, and leveraging our relationships to penetrate their other products.
Leverage global business model for cost-effective growth

We intend to continue to leverage our global resources and regional strengths. We will continue to deploy marketing, sales and technical support teams in close proximity to our end customers. We plan to further expand and align our technical marketing and application support teams along with our sales team to better understand and address the needs of our end customers and their end-market applications, in particular for those with the new technology platforms developed in this past year and in the future. This will assist us in identifying and defining new technology trends and products and to help us gain additional design wins.
Our products

To serve the large and diverse analog market for power semiconductors, we have created a broad product portfolio consisting of two major categories: power discretes and power ICs.

Our power discretes products consist primarily of low, medium and high voltage power MOSFETs. Our low-voltage MOSFET series is based on our proprietary technology, which offers increased efficiency and performance by reducing on-resistance and switching losses. We also introduced the XSFET packaging technology platform to provide a high thermal performance solution for advanced computing and high efficiency telecommunications and industrial applications. Our mid-voltage MOSFET portfolio offers high efficiency solutions for advanced telecommunications and industrial power supply applications. Our high-voltage portfolio includes our proprietary insulated-gate bipolar transistor ("IGBT") technology, which we developed highly robust and easy-to-use solutions designed for industrial motor control and white goods applications.

Our power ICs deliver power as well as control and regulate the power management variables, such as the flow of current and level of voltage. We continued to expand our EZBuck power IC family with products that feature lower on-resistance, small footprint and thermally enhanced packages. While we derive the majority of our revenue from the sales of power discretes products, sales of power ICs have been gaining traction during the past years.

Power discrete products

Power discretes are used across a wide voltage and current spectrum, requiring them to operate efficiently and reliably under harsh conditions. Due to this wide applicability across diverse end-market applications, we market general purpose MOSFETs that are used in multiple applications as well as MOSFETs targeted for specific applications.

Our current power discrete product line includes industry standard trench MOSFETs, SRFETs, XSFET, electrostatic discharge, protected MOSFETs, high and mid-voltage MOSFETs and IGBTs.
Power IC products

In addition to the traditional monolithic or single chip design, we employ a multi-chip approach for the majority of our power ICs. This multi-chip technique leverages our proprietary MOSFET and advanced packaging technologies to offer integrated solutions to our customers. This allows us to update a product by interchanging only the MOSFETs without changing the power management IC, thereby reducing the time required for new product introduction. We believe that our power IC products improve our competitive position by enabling us to provide higher power density solutions to our end customers than our competitors.

The incorporation of both power delivery and power management functions tends to make power ICs more application specific because these two functions have to be properly matched to a particular end product. We have local technical marketing and applications engineers who closely collaborate with our end customers to help ensure that power IC specifications are properly defined at the beginning of the design stage.
New Product Introduction

As part our strategy to diversify SAM, we introduced several new products based on our proprietary technology platform during past fiscal year. In the quarter ended September 30, 2013, we released seven new power discrete products in our 600V AlphalGBT portfolio with IGBT solutions ranging from 20A to 60A in the TO247 package. These new products are suitable for a wide variety of applications including household appliances, commercial HVAC systems, photovoltaic inverters, and industrial equipment. In addition, during the quarter ended June 30, 2014, we released new 1350V IGBT optimized for induction heating applications. The device reduces the risk of avalanche destruction from voltage transients. In the quarter ended December 31, 2013, we also introduced a new lower voltage dual MOSFET family in the common-drain configuration in

5


both DFN 5x6 and Micro-DFN 3.2x2 packages. These devices are suitable for battery pack applications to enhance battery pack performance in the latest generation Ultrabooks and tablets, where low conduction loss is essential for optimizing battery life.

For the power IC products, we continue to expand the product family by introducing new solutions to computing and LED back lighting for LCD-TV. During the quarter ended September 30, 2013, we introduced a new generation of high efficiency DrMos power modules. The new device enables higher power density voltage regulator solutions which is ideal for servers, work stations, graphic cards and high-end desktop PC applications. In addition, in the same quarter, we launched a third-generation high efficiency power module with an EZPair package. This new device enables high power density voltage regulator solutions which is ideal for notebook PCs, servers, and graphic cards applications. Moreover, in the quarter ended June 30, 2014, we released dual-channel EZPower Smart Load Switch that delivers up to 6A per channel of continuous current. These devices offer industry leading performance and allow the ideal load switch for a variety of applications.
Distributors and customers
We have developed direct relationships with key OEMs, most of which we serve through our distributors and ODMs. They include Dell Inc., Hewlett-Packard Company, LG Electronics, Inc. and Samsung Group. We sell to Samsung Group directly which accounted for 11.6%, 13.0% and 13.9% of our revenue for the fiscal years ended June 30, 2014, 2013 and 2012, respectively. In addition, based on our historical design win activities, our power semiconductors are also incorporated into products sold to certain OEMs.
Through our distributors, we provide products to ODMs who traditionally are contract manufacturers for OEMs. As the industry has evolved, ODMs are increasingly responsible for designing portions, or entire systems, of the products they manufacture for the OEMs. In addition, several ODMs are beginning to design, manufacture and brand their own proprietary products, which they sell directly to consumers. Our ODM customers include Compal Electronics, Inc., Foxconn, Quanta Computer Incorporated, Pegatron,Wistron Corporation and AOC International.
In order to take advantage of the expertise of end-customer fulfillment logistics and shorter payment cycles, we sell most of our products to distributors. Under the agreements with our distributors, they have limited rights to return unsold merchandise, subject to time and volume limitations. As of June 30, 2014 and June 30, 2013, the two largest distributors of our products were WPG Holdings Limited, or WPG, and Promate Electronic Co. Ltd., or Promate. Sales to WPG and Promate accounted for 43.1% and 21.6% of our revenue for the fiscal year ended June 30, 2014, respectively, 41.6% and 24.4% of our revenue for the fiscal year ended June 30, 2013, respectively, and 40.9% and 24.0% of our revenue for fiscal year ended June 30, 2012, respectively.
Sales and marketing

Our marketing department is responsible for identifying high growth markets and applications where we believe our technology can be effectively deployed. We believe that the technical background of our marketing team, including technical marketing engineers, helps us better define new products and identify potential end customers and geographic and product market opportunities. For example, as part of our market diversification strategy, we have deployed and plan to recruit more for our new market segments, field application engineers, or FAEs, who provide real-time and on-the-ground responses to our end customer needs, work with our end customers to understand their requirements, resolve technical problems, strive to anticipate future customer needs and facilitate the design-in of our products into the end products of our customers. We believe this strategy increases our share of revenue opportunities within the applications we currently serve, as well as in new end-market applications.

Our sales team consisted of sales persons, field application engineers, customer service representatives and customer quality engineers who are responsible for key accounts. We strategically position our team near our end customers through our offices in Taipei, Hong Kong, Shenzhen, Shanghai, Tokyo, Seoul and Sunnyvale, California, complemented by our applications centers in Sunnyvale and Shanghai. In addition, our distributors and sales representatives assist us in our sales and marketing efforts by identifying potential customers, sourcing additional demand and promoting our products, in which case we may pay a sales commission to these distributors.
A typical sales cycle takes six to nine months and is comprised of the following steps:
identification of a customer design opportunity;
qualification of the design opportunity by our FAEs through comparison of the power requirements against our product portfolio;

6


provision of a product sample to the end customer to be included in the customer's pre-production model with the goal of being included in the final bill of materials; and
placement by the customer, or through its distributor, of a full production order as the end customer increases to full volume production.
Competition    

The power semiconductor industry is characterized by fragmentation with many competitors. We compete with different power semiconductor suppliers, depending on the type of product lines and geographical area. Our key competitors in power discretes and power ICs are primarily headquartered in the United States, Japan, Europe and Taiwan. Our major competitors in power discretes include Fairchild Semiconductor International, Inc., Infineon Technologies AG, International Rectifier Corporation, MagnaChip Semiconductor Corporation, ON Semiconductor Corp., STMicroelectronics N.V., Toshiba Corporation, Diodes Incorporated and Vishay Intertechnology, Inc. Our major competitors for our power ICs include Global Mixed-mode Technology Inc., Monolithic Power Systems, Inc., Richtek Technology Corp., Semtech Corporation and Texas Instruments Inc.

Our ability to compete depends on a number of factors, including:

our success in expanding and diversifying our serviceable markets, and our ability to develop technologies and product solutions for these markets;

our capability in quickly developing and introducing proprietary technology and best in class products;

the performance and cost-effectiveness of our products relative to that of our competitors;

our ability to manufacture, package and deliver products in large volume on a timely basis at a competitive price;

our success in utilizing new and proprietary technologies to offer products and features previously not available in the marketplace;

our ability to recruit and retain analog semiconductor designers and application engineers; and

our ability to protect our intellectual property.

Some of our competitors have longer operating histories, more brand recognition, and significantly greater financial, technical, research and development, sales and marketing, manufacturing and other resources. However, we believe that we can compete effectively through our integrated and innovative technology platform and design capabilities, including our multi-chip approach to power IC products, strategic global business model, expanding portfolio of products, diversified and broad customer base, and excellent on-the-ground support and quick time to market for our products.
 Seasonality
As we provide power semiconductors used in consumer electronic products, our business is subject to seasonality. Our sales seasonality is affected by a number of factors, including global and regional economic conditions as well as the PC market conditions, revenue generated from new products, changes in distributor ordering patterns in response to channel inventory adjustments and end customer demand for our products and fluctuations in consumer purchase patterns prior to major holiday seasons. In recent periods, broad fluctuations in the semiconductor markets and the global and regional economic conditions, in particular the decline of the PC market conditions, have had a more significant impact on our results of operations than seasonality, and have made it difficult to assess the impact of seasonal factors on our business.
Backlog
Our sales are made primarily pursuant to standard purchase orders from distributors and direct customers. The amount of backlog to be shipped during any period depends on various factors, and all orders are subject to cancellation or modification, usually with no penalty to customers. The quantities actually purchased by customers, as well as shipment schedules, are frequently revised to reflect changes in both the customers' requirements and in manufacturing availability. Therefore, our backlog at any point in time is not a reliable indicator of our future revenue.

Research and development

Because we view technology as a competitive advantage, we invest significant time and capital into research and development to address the technology intensive needs of our end customers. Our research and development expenditures for the fiscal years of 2014, 2013 and 2012 were $24.4 million, $27.8 million and $30.6 million, respectively. Our research and development expenditures primarily consist of staff compensation, prototypes, engineering materials, simulation and design tools and test and analyzer equipment. Our new product development efforts continue to focus on developing products with higher speed, higher efficiency and reliability, higher power density, greater performance and lower costs. We have research and development teams in Silicon Valley (Sunnyvale, California), Oregon, Taipei, Taiwan, and Shanghai, China. We believe that these diverse research and development teams enables us to develop leading edge technology platforms and new products. Our areas of research and development focus include:

Packaging technologies: Consumer demand for smaller and more compact electronic devices with higher power density is driving the need for advanced packaging technology. Our group of dedicated packaging engineers focuses on smaller form factor, higher power output with efficient heat dissipation and cost-effectiveness. We have invested significant resources to develop and enhance our proprietary packaging technologies, including the establishment of our in-house packaging and testing facilities. We believe that our efforts to develop innovative packaging technologies will continue to provide new and cost-effective solutions with higher power density to our customers. During the fiscal year ended June 30, 2014, we continued our diversification program by developing new silicon and packaging platforms to expand our SAM and offer higher performanced products.
Process technology and device physics: We focus on specialized process technology in the manufacturing of our products, including vertical DMOS, Shielded Gate Trench, Trench field stop IGBTs, charge-balance high voltage MOSFETs, Schottky Diode and BCDMOS processes. Our process engineers work closely with our design team to deploy and implement our proprietary manufacturing processes at our Oregon fab as well as the third-party foundries that fabricate our wafers. To improve our process technology, we continue to develop and enhance our expertise in device physics in order to better understand the physical characteristics of materials and the interactions among these materials during the manufacturing process.

New products and new technology platforms: We also invest significantly in the development of new technology platforms and introduction of new products. Because power management affects all electronic systems, we believe that developing a wide portfolio of products enables us to target new applications in addition to expanding our share of power management needs served within existing applications.
As a technology company, we will continue our significant investment in research and development in our low voltage and high voltage power discretes and power ICs by developing new technology platforms and new products that allow for better product performance, more efficient packages and higher levels of integration.
Operations

The manufacture of our products is divided into two major steps: wafer fabrication and packaging and testing.
Wafer fabrication
    
We have transitioned from a fabless to a “fab-lite” business model through the acquisition of the Oregon fab in January 2012. We believe our Oregon fab allows us to accelerate the development of our technology and products, as well as to provide better services to our customers. We allocate our wafer production between our in-house facility and third-party foundries, although in the past three years, we have gradually reduced our reliance on third-party foundries following the acquisition and integration of the Oregon fab. Currently our main third-party foundry is Shanghai Hua Hong Grace Electronic Company Limited, ("HHGrace"), or formerly HHNEC, located in Shanghai. HHGrace has been manufacturing wafers for us since 2002. HHGrace manufactured 28.6%, 37.7% and 49.9% of the wafers used in our products for the fiscal years ended June 30, 2014, 2013 and 2012, respectively.
Packaging and testing

Completed wafers from the foundries are sent to our in-house packaging and testing facilities or to our subcontractors, where the wafers are cut into individual die, soldered to lead frames, wired to terminals and then encapsulated in protective packaging. After packaging, all devices are tested in accordance with our specifications and substandard or defective devices are rejected. We have established quality assurance procedures that are intended to control quality throughout the manufacturing process, including qualifying new parts for production at each packaging facility, conducting root cause

8


analysis, testing for lots with process defects and implementing containment and preventive actions. The final tested products are then shipped to our distributors or customers.

Our in-house packaging and testing facilities are located in Shanghai, China which handle most of our packaging and testing requirements for our products, and we outsource a small portion of our packaging and testing requirements to other contract manufacturers. Our facilities have the combined capacity to package and test over 500 million parts per month and have available floor space for new package introductions. We believe our ability to package and test our products internally represents a strategic advantage as it protects our proprietary packaging technology, increases the rate of new package introductions, reduces operating expenses and ultimately improves our profit margins.

Quality assurance

Our quality assurance practices aim to consistently provide our end customers with products that are reliable, durable and free of defects. We strive to do so through continuous improvement in our product design and manufacturing and close collaboration with our manufacturing partners. Our manufacturing operations in China received ISO9001 Quality Management System certification in recognition of our quality assurance standards and we have maintained certification to the ISO 9001 standard. Our manufacturing facility in Oregon is also certified to the ISO 9001 standard. ISO9001 is a set of criteria and procedures established by International Organization of Standardization for developing a fundamental quality management system and focusing on continuous improvement, defect prevention and the reduction of variation and waste. We also offer lead-free products in order to comply with Restrictions on the use of Hazardous Substances, or RoHS.

We maintain a supplier management and process engineering team in Shanghai that works with our third-party foundries and packaging and testing subcontractors to monitor the quality of our products, which is designed to ensure that manufacturing of our products, is in strict compliance with our process control, monitoring procedures and product requirements. We also conduct periodic reviews and annual audits to ensure supplier performance. For example, we examine the results of statistical process control systems, implement preventive maintenance, verify the status of quality improvement projects and review delivery time metrics. In addition, we rate and rank each of our suppliers every quarter based on factors such as their quality and performance. Our facility in Oregon integrates manufacturing process controls through our manufacturing execution system coupled with wafer process controls that include monitoring procedures, preventative maintenance, statistical process control, and testing to ensure that finished wafers delivered will meet and exceed quality and reliability requirements. All materials used to manufacture wafers are controlled through a strict qualification process.

Our manufacturing processes use many raw materials, including silicon wafers, gold, copper, molding compound, petroleum and plastic materials and various chemicals and gases. We obtain our raw materials and supplies from a large number of sources. Although supplies for the raw materials used by us are currently adequate, shortages could occur in various essential materials due to interruption of supply or increased demand in the industry.
Intellectual property rights
Intellectual property is a critical component of our business strategy, and we intend to continue to invest in the growth, maintenance and protection of our intellectual property portfolio. We own significant intellectual property in many aspects of power semiconductor technology, including device physics and structure, wafer processes, circuit designs, packaging, modules and subassemblies. We have also entered into intellectual property licensing agreements with other companies, including Fairchild Semiconductor International, Inc. and Giant Semiconductor Corporation, to use selected third-party technology for the development of our products, although we do not believe our business is dependent to any significant degree on any individual third-party license.

While we focus our patent efforts in the United States, we file corresponding foreign patent applications in other jurisdictions, such as China and Taiwan, when filing is justified by cost and strategic importance. The patents are increasingly important to remain competitive in our industry, and a strong patent portfolio will facilitate the entry of our products into new markets. As of June 30, 2014, we had 420 patents issued in the United States, of which 39 were acquired, 2 were licensed and 379 were based on our research and development efforts, and these patents are set to expire between 2015 and 2032. We also had a total of 328 foreign patents, including 176 Chinese patents, 141 Taiwanese patents, 6 Korean patents, 4 Hong Kong patents and 1 Japanese patent as of June 30, 2014. Substantially all of our foreign patents were based on our research and development efforts. These foreign patents expire in the years between 2015 and 2030. In addition, as of June 30, 2014, we had a total of 643 patent applications, of which 213 patents were pending in the United States, 239 patents were pending in China, 178 patents were pending in Taiwan and 13 patents were pending in other countries.

As our technologies are deployed in new applications and as we diversify our product portfolio based on new technology platforms, we may be subject to new potential infringement claims. Patent litigation, if and when instituted against us, could result in substantial costs and a diversion of our management's attention and resources. However, we are committed to vigorously defending and protecting our investment in our intellectual property. Therefore, the strength of our intellectual property program, including the breadth and depth of our portfolio, will be critical to our success in the new markets we intend to pursue.
In addition to patent protection, we also rely on a combination of trademark, copyright (including mask work protection), trade secret laws, contractual provisions and similar laws in other jurisdictions. We also enter into confidentiality and invention assignment agreements with our employees, consultants, suppliers, distributors and customers and seek to control access to, and distribution of, our proprietary information.
Environmental matters

The semiconductor production process, including the semiconductor wafer manufacturing and packaging process, generates air emissions, liquid wastes, waste water and other industrial wastes. We have installed various types of pollution control equipment for the treatment of air emissions and liquid waste and equipment for recycling and treatment of water in our packaging and testing facilities in China and wafer manufacturing facility in Oregon, USA. Waste generated at our manufacturing facilities, including but not limited to acid waste, alkaline waste, flammable waste, toxic waste, oxide waste and self-igniting waste, is collected and sorted for proper disposal. Our operations in China are subject to regulation and periodic monitoring by China's State Environmental Protection Bureau, as well as local environmental protection authorities, including those under the Shanghai Municipal Government, which may in some cases establish stricter standards than those imposed by the State Environmental Protection Bureau. Our operation in Oregon is subject to Oregon Department of Environmental Regulations, Federal Environmental Protection Agency laws and regulations, and local jurisdictional regulations. We believe that we have been in material compliance with applicable environmental regulations and standards and have not had a material or adverse effect on our results of operations from complying with these regulations.

We have implemented an ISO 14001 environmental management system in our manufacturing facilities in China and Oregon. We also require our subcontractors, including foundries and assembly houses, to meet ISO14001 standards. We believe that we have adopted pollution control measures for the effective maintenance of environmental protection standards consistent with the requirements applicable to the semiconductor industry in China and the U.S..

Our products sold in Europe are subject to RoHS in Electrical and Electronic Equipment, which requires that the products do not contain more than agreed levels of lead, cadmium, mercury, hexavalent chromium, polybrominated biphenyl and polybrominated diphenyl ether flame retardants. Our manufacturing facilities in China also obtained QC080000 certification, which is an IECQ Certificate of Conformity Hazardous Substance Process Management for European Directive 2002/95/EC requirements and a Certificate of Green Partner for Sony Green Partner Program. We avoid using these restricted materials to the extent possible when we design our products.

We are also subject to SEC rules that require diligence, disclosure and reporting on whether certain minerals and metals, known as conflict minerals, used in our products originate from the Democratic Republic of Congo and adjoining countries. As of June 30, 2014, we have implemented and are in compliance with the related conflict minerals rule.
Employees
As of June 30, 2014, we had approximately 2,750 employees, of which approximately 360 were located in the United States, 2,310 were located in China, and 80 were located in other parts of Asia. Of the total employees, approximately 2,350 were in operations and manufacturing, 150 were in research and development, 130 were in sales and marketing and 120 were in general and administrative. None of our employees are represented by a collective bargaining agreement and we have never experienced a work stoppage due to labor issues. We consider our relationships with our employees to be good.

Item 1A.
Risk Factors
Risks Related to Our Business
Our operating results may fluctuate from period to period due to many factors, which may make it difficult to predict our future performance.
Our periodic operating results may fluctuate as a result of a number of factors, many of which are beyond our control. These factors include, among others:

a deterioration in general demand for electronic products, particularly the Personal Computing (PC) market, as a result of global or regional financial crises and associated macro-economic slowdowns, and/or the cyclicality of the semiconductor industry;
a deterioration in business conditions at our distributors and /or end customers;
adverse general economic conditions in the countries where our products are sold or used;
the emergence and growth of markets for products we are currently developing;
our ability to successfully develop, introduce and sell new or enhanced products in a timely manner and the rate at which our new products replace declining orders for our older products;
the anticipation, announcement or introduction of new or enhanced products by us or our competitors;
the amount and timing of operating costs and capital expenditures, including expenses related to the maintenance and expansion of our business operations and infrastructure;
the announcement of significant acquisitions, disposition or partnership arrangements;
changes in the utilization of our in-house manufacturing capacity;
supply and demand dynamics and the resulting price pressure on the products we sell;
the unpredictable volume and timing of orders, deferrals, cancellations and reductions for our products, which may depend on factors such as our end customers' sales outlook, purchasing patterns and inventory adjustments based on general economic conditions or other factors;
changes in the selling prices of our products and in the relative mix in the unit shipments of our products, which have different average selling prices and profit margins;
changes in costs associated with manufacturing of our products, including pricing of wafer, raw materials and assembly services;
our concentration of sales in consumer applications and changes in consumer purchasing patterns and confidence; and
the adoption of new industry standards or changes in our regulatory environment;
Any one or a combination of the above factors and other risk factors described in this section may cause our operating results to fluctuate from period to period, making it difficult to predict our future performance. Therefore, comparing our operating results on a period-to-period basis may not be meaningful, and you should not rely on our past results as an indication of our future performance.

The decline of personal computing (“PC”) markets may have a material adverse effect on our results of operations, and our efforts to diversify our products may not be sufficient to mitigate the impact of the declining PC markets.

A significant amount of our revenue is derived from sales of products in the PC markets such as notebooks, motherboards and notebook battery packs.  Our revenue from the PC markets accounted for approximately 45.2%, 50.0% and 54.4% of our total revenue for the years ended 2014, 2013 and 2012, respectively. The increasing popularity of smaller, mobile computing devices such as tablets and smartphones with touch interfaces is rapidly changing the PC markets both in the United States and abroad.  Recently, we experienced a significant reduction in the demand for our products due to the declining PC markets, particularly from our distributors and customers in Taiwan, which have negatively impacted our revenue and profitability.

The decline of the PC markets may also adversely affect our ability to adjust inventory levels in response to the lower shipments, which may negatively impact our gross margins. During the quarter ended March 31, 2013, we recorded a non-cash, non-recurring inventory valuation charge of $5.7 million primarily related to excess and obsolete inventory consisting of

13


PC-related products that were not compatible with a particular OEM's applications and were deemed not saleable. Moreover, the continuing decline of the PC markets may reduce the capacity utilization of our manufacturing facilities or impair the value of our long-lived assets, including equipment and machinery used for the manufacturing and packaging of our products, which could have a material adverse effect on our results of operations.

Our diversification into different market segments may not succeed according to our expectations and may expose us to new risks and place significant strains on our management, operational, financial and other resources.

As part of the growth strategy to diversify our product portfolio and in response to the rapid decline of the PC markets, we have been developing new technologies and products designed to penetrate into other markets and applications, including merchant power supplies, flat panel TVs, smart phones, tablets, gaming consoles, lighting, datacom, home appliances and industrial motor controls. However, there is no guarantee that these diversification efforts will be successful. As a new entrant to some of these markets, we may face intense competition from existing and more established providers and encounter other unexpected difficulties, any of which may hinder or delay our efforts to achieve success. In addition, our new products may have long design and sales cycles, therefore if our diversification efforts fail to keep pace with the declining PC markets, we may not be able to alleviate its negative impact on our results of operations.

Our diversification into different market segments may place a significant strain on our management, operational, financial and other resources. To manage this diversification effectively, we will need to take various actions, including:
enhancing management information systems, including forecasting procedures;
further developing our operating, administrative, financial and accounting systems and controls;
managing our working capital and sources of financing;
maintaining close coordination among our engineering, accounting, finance, marketing, sales and operations organizations;
retaining, training and managing our employee base;
enhancing human resource operations and improving employee hiring and training programs;
realigning our business structure to more effectively allocate and utilize our internal resources;
improving and sustaining our supply chain capability; and
managing both our direct and distribution sales channels in a cost-efficient and competitive manner.

Our failure to execute any of the above actions successfully or timely may have an adverse effect on our business and financial results.
Our revenue may fluctuate significantly from period to period due to ordering patterns from our distributors and seasonality.
Demand for our products from our end customers fluctuates depending on their sales outlooks and market and economic conditions. Accordingly, our distributors place purchase orders with us based on their forecasts of end customer demand. Because these forecasts may not be accurate, channel inventory held at our distributors may fluctuate significantly due to the difference between the forecasts and actual demand. As a result, distributors adjust their purchase orders placed with us in response to changing channel inventory levels, as well as their assessment of the latest market demand trends. A significant decrease in our distributors' channel inventory in one period may lead to a significant rebuilding of channel inventory in subsequent periods, or vice versa, which may cause our quarterly revenue and operating results to fluctuate significantly.
In addition, because our power semiconductors are used in consumer electronics products, our revenue is subject to seasonality. Our sales seasonality is affected by a number of factors, including global and regional economic conditions as well as the PC market conditions, revenue generated from new products, changes in distributor ordering patterns in response to channel inventory adjustments and end customer demand for our products and fluctuations in consumer purchase patterns prior to major holiday seasons. In recent year, broad fluctuations in the semiconductor markets and the global economic conditions, in particular the decline of the PC market conditions, have had a more significant impact on our results of operations, than seasonality, and have made it difficult to assess the impact of seasonal factors on our business.

If we are unable to introduce or develop new and enhanced products that meet or are compatible with our customer's product requirements in a timely manner, it may harm our business, financial position and operating results.


14


Our success depends upon our ability to develop and introduce new and enhanced products that meet or are compatible with our customer's specifications, performance standards and other product requirements in a timely manner. The development of new and enhanced products involves highly complex processes, and at times we have experienced delays in the introduction of new products. Successful product development and introduction of new products depends on a number of factors, including the accurate product specification; timely completion of design; achievement of manufacturing yields; timely response to changes in customers' product requirements; quality and cost-effective production; and effective marketing. Since many of our products are designed for specific applications, we must frequently develop new and enhanced products jointly with our customers. In the past, we have encountered product compatibility issues with a major OEM that has negatively impacted our financial results, and although we have resolved fully such issues with the OEM, there is no guarantee that the same compatibility issues will not occur in the future with other OEMS. If we are unable to develop or acquire new products that meet or are compatible with our customer's specification and other product requirements in a timely manner, we may lose revenue or market shares with our customers, which could have a material adverse effect on our business, financial position and operating results.
We may not win sufficient designs, or our design wins may not generate sufficient revenue for us to maintain or expand our business.
We invest significant resources to compete with other power semiconductor companies to obtain winning competitive bids for our products in selection processes, known as “design wins.” Our effort to obtain design wins may detract us from or delay the completion of other important development projects, impair our relationships with existing end customers and negatively impact sales of products under development. In addition, we cannot be assured that these efforts would result in a design win, that our product would be incorporated into an end customer's initial product design, or that any such design win would lead to production orders and generate sufficient revenue. Furthermore, even after we have qualified our products with a customer and made sales, subsequent changes to our products, manufacturing processes or suppliers may require a new qualification process, which may result in delay and excess inventory. If we cannot achieve sufficient design wins in the future, or if we fail to generate production orders following design wins, our ability to grow our business and improve our financial results will be harmed.
Our success depends upon the ability of our OEM end customers to successfully sell products incorporating our products.
The consumer end markets, in particular the PC market, in which our products are used are highly competitive. Our OEM end customers may not successfully sell their products for a variety of reasons, including:
general global and regional economic conditions;
late introduction or lack of market acceptance of their products;
lack of competitive pricing;
shortage of component supplies;
excess inventory in the sales channels into which our end customers sell their products;
changes in the supply chain; and
changes as a result of regulatory restrictions applicable to China-exported products.
 Our success depends on the ability of our OEM end customers to sell their products incorporating our products. In addition, we have expanded our business model to include more OEMs in our direct customer base. The failure of our OEM end customers to achieve or maintain commercial success for any reason could harm our business, results of operations, and financial condition and prospects.

We expect to incur significant fixed manufacturing costs in connection with the operation of our Oregon fab, which may negatively impact our results of operations, and the operation of our own fabrication facility may subject us to additional risks and the need for additional capital expenditures.
 
The operation of our own fabrication facility requires significant fixed manufacturing cost. In order to manage the capacity of the wafer fabrication facility efficiently, we must perform a forecast of long-term market demand and general economic conditions for our products. Because market conditions may vary significantly and unexpectedly, our forecast may change significantly at any time, and we may not be able to make timely adjustments to our fabrication capacity in response to these changes. During periods of continued decline in market demand, in particular the decline of the PC market, we may not be able to absorb the excess inventory and additional costs associated with operating the facility at higher capacity, which may adversely affect our operating results. Similarly, during periods of unexpected increase in customer demand, we may not be

15


able to ramp up production quickly to meet these demands, which may lead to the loss of significant revenue opportunities. The manufacturing processes of a fabrication facility are complex and subject to interruptions. We may experience production difficulties, including lower manufacturing yields or products that do not meet our or our customers' specifications, and problems in ramping production and installing new equipment. These difficulties could result in delivery delays, quality problems and lost revenue opportunities. Any significant quality problems could also damage our reputation with our customers and distract us from the development of new and enhanced product which may have a significant negative impact on our financial results.

In addition, semiconductor manufacturing has historically required an upgrading of process technology from time to time to remain competitive, as new and enhanced semiconductor processes are developed which permit smaller, more efficient and more powerful semiconductor devices. Accordingly, we may have to make substantial capital expenditures and install significant production capacity at our in-house fabrication facility to support new technologies and increased production volume, which may cause delay in our ability to deliver new products or negatively impact our results of operations.
Defects and poor performance in our products could result in loss of customers, decreased revenue, unexpected expenses and loss of market share, and we may face warranty and product liability claims arising from defective products.
Our products are complex and must meet stringent quality requirements. Products as complex as ours may contain undetected errors or defects, especially when first introduced or when new versions are released. Errors, defects or poor performance can arise due to design flaws, defects in raw materials or components or manufacturing anomalies, which can affect both the quality and the yield of the product. It can also be potentially dangerous as defective power components, or improper use of our products by customers, may lead to power overloads, which could result in explosion or fire. As our products become more complex, we face higher risk of undetected defects, because our testing protocols may not be able to fully test the products under all possible operating conditions. In the past, we have experienced defects in our products and these products were returned to us and subsequently scrapped or sold at a discount. Any actual or perceived errors, defects or poor performance in our products could result in the replacement or recall of our products, shipment delays, rejection of our products, damage to our reputation, lost revenue, diversion of our engineering personnel from our product development efforts in order to address or remedy any defects and increases in customer service and support costs, all of which could have a material adverse effect on our business and operations.
Furthermore, as our products are typically sold at prices much lower than the cost of the equipment or other devices incorporating our products, any defective, inefficient or poorly performing products, or improper use by customers of power components, may give rise to warranty and product liability claims against us that exceed any revenue or profit we receive from the affected products. Historically, we have received claims from our customers for charges such as their labor and other costs replacing defective parts, their lost profit, and/or penalty. We could incur significant costs and liabilities if we are sued and if damages are awarded against us. There is no guarantee that our insurance policies will be available or adequate to protect against such claims. Costs or payments we may make in connection with warranty and product liability claims or product recalls may adversely affect our financial condition and results of operations.
If we do not forecast demand for our products accurately, we may experience product shortages, delays in product shipment, excess product inventory, or difficulties in planning expenses, which will adversely affect our business and financial condition.
We manufacture our products according to our estimates of customer demand. This process requires us to make multiple forecasts and assumptions relating to the demand of our end customers, channel inventory, and general market conditions. Because we sell most of our products to distributors, who in turn sell to our end customers, we have limited visibility as to end customer demand. Furthermore, we do not have long-term purchase commitments from our distributors or end customers, and our sales are generally made by purchase orders that may be cancelled, changed or deferred without notice to us or penalty. As a result, it is difficult to forecast future customer demand to plan our operations.

The utilization of our manufacturing facilities and the provisions for inventory write-downs are important factors in our profitability. If we overestimate demand for our products, or if purchase orders are canceled or shipments delayed, we may have excess inventory, which may result in adjustments to our production plans. These adjustments to our productions may affect the utilization of our own wafer fabrication and packaging facilities. If we cannot sell certain portion of the excess inventory, it will affect our provisions for inventory write-downs. Our inventory write-down provisions are subject to adjustment based on events that may not be known at the time the provisions are made, and such adjustments could be material and impact our financial results negatively.


16


If we underestimate demand, we may not have sufficient inventory to meet end-customer demand, and we may lose market share and damage relationships with our distributors and end customers and we may have to forego potential revenue opportunities. Obtaining additional supply in the face of product shortages may be costly or impossible, particularly in the short term, which could prevent us from fulfilling orders in a timely manner or at all.
In addition, we plan our operating expenses, including research and development expenses, hiring needs and inventory investments, base in part on our estimates of customer demand and future revenue. If customer demand or revenue for a particular period is lower than we expect, we may not be able to proportionately reduce our fixed operating expenses for that period, which would harm our operating results.
We face intense competition and may not be able to compete effectively which could reduce our revenue and market share.
The power semiconductor industry is highly competitive and fragmented. If we do not compete successfully against current or potential competitors, our market share and revenue may decline. Our main competitors are primarily headquartered in the United States, Japan, Taiwan and Europe. Our major competitors for our power discretes include Diodes Incorporated, Fairchild Semiconductor International, Inc., Infineon Technologies AG, International Rectifier Corporation, MagnaChip Semiconductor Corporation, ON Semiconductor Corporation, STMicroelectronics N.V., Toshiba Corporation and Vishay Intertechnology, Inc. Our major competitors for our power ICs include Global Mixed-mode Technology Inc., Monolithic Power Systems, Inc., Richtek Technology Corp., Semtech Corporation and Texas Instruments Inc. We expect to face competition in the future from our competitors, other manufacturers, designers of semiconductors and start-up semiconductor design companies. Many of our competitors have competitive advantages over us, including:
significantly greater financial, technical, research and development, sales and marketing and other resources, enabling them to invest substantially more resources than us to respond to the adoption of new or emerging technologies or changes in customer requirements;
greater brand recognition and longer operating histories;
larger customer bases and longer, more established relationships with distributors or existing or potential end customers, which may provide them with greater reliability and information regarding future trends and requirements that may not be available to us;
the ability to provide greater incentives to end customers through rebates, and marketing development funds or similar programs;
more product lines, enabling them to bundle their products to offer a broader product portfolio or to integrate power management functionality into other products that we do not sell; and
captive manufacturing facilities, providing them with guaranteed access to manufacturing facilities in times of global semiconductor shortages.
If we are unable to compete effectively for any of the foregoing or other reasons, our business, results of operations, and financial condition and prospects will be harmed.

We depend partly on third-party semiconductor foundries to manufacture our products and implement our fabrication processes, and any failure to maintain sufficient foundry capacity and control the cost of production could significantly delay our ability to ship our products, damage our relationships with customers, reduce our sales and increase expenses.

Under our “fab Lite” business model in which the allocation of our wafer production between in-house facility and third-party foundries may fluctuate from time to time. Nevertheless, we expect to continue to rely in part on third party foundries to meet our wafer requirements. Although we use several independent foundries, our primary third-party foundry is HHGrace, which manufactured 28.6%, 37.7% and 49.9% of the wafers used in our products for the fiscal years ended June 30, 2014, 2013 and 2012, respectively.

We place our purchase orders with foundries based on sales forecasts for our products. If any third-party foundry does not provide competitive pricing or is not able to meet our required capacity for any reason, we may not be able to obtain the required capacity to manufacture our products timely or efficiently. If we cannot maintain sufficient capacity or control pricing with our existing third-party foundries, we may need to increase our own manufacturing capacity, and there is no assurance that we can ramp up the production of the Oregon fab timely to meet the increased demand. If not, we may need to seek alternative foundries, which may not be available on commercially reasonable terms, or at all. In addition, the process for qualifying a new foundry is time consuming, difficult and may not be successful, particularly if we cannot integrate our proprietary process technology with the process used by the new foundry. Using a foundry with which we have no established relationship could expose us to potentially unfavorable pricing, unsatisfactory quality or insufficient capacity allocation.

17



In addition, even though we have been transferring more new product developments to our Oregon fab, we still rely on third-party foundries significantly to effectively implement certain of our proprietary technology and processes and also require their cooperation in developing new fabrication processes. Any failure to do so may impair our ability to introduce new products and on time delivery of wafers for our existing products. In order to maintain our profit margins and to meet our customer demand, we need to achieve acceptable production yields and timely delivery of silicon wafers. As is common in the semiconductor industry, we have experienced, and may experience from time to time, difficulties in achieving acceptable production yields and timely delivery from third-party foundry vendors. Minute impurities in a silicon wafer can cause a substantial number of wafers to be rejected or cause numerous die on a wafer to be defective. Low yields often occur during the production of new products, the migration of processes to smaller geometries or the installation and start up of new process technologies.
 
We face a number of other significant risks associated with outsourcing fabrication, including:

limited control over delivery schedules, quality assurance and control and production costs;

discretion of foundries to reduce deliveries to us on short notice, allocate capacity to other customers that may be larger or have long-term customer or preferential arrangements with foundries that we use;

unavailability of, or potential delays in obtaining access to, key process technologies;

limited warranties on wafers or products supplied to us;

damage to equipment and facilities, power outages, equipment or materials shortages that could limit manufacturing yields and capacity at the foundries;

potential unauthorized disclosure or misappropriation of intellectual property, including use of our technology by the foundries to make products for our competitors;

financial difficulties and insolvency of foundries; and

acquisition of foundries by third parties.

 Any of the foregoing risks could delay shipment of our products, result in higher expenses and reduced revenue, damage our relationships with customers and otherwise adversely affect our business and operating results.
Our operation of two in-house packaging and testing facilities are subject to risks that could adversely affect our business and financial results.

We have two in-house packaging and testing facilities located in Shanghai, China that handle most of our packaging and testing requirements. The operation of high-volume packaging and testing facilities and implementation of our advanced packaging technology are complex and demand a high degree of precision and may require modification to improve yields and product performance. We have committed substantial resources to ensure that our packaging and testing facilities operate efficiently and successfully, including the acquisition of equipment and raw materials, and training and management of a large number of technical personnel and employees. Due to the fixed costs associated with operating our own packaging and testing facilities, if we are unable to utilize our in-house facilities at a desirable level of production, our gross margin and results of operations may be adversely affected. For example, a significant decline in our market share or sales orders may negatively impact our factory utilization and reduce our ability to achieve profitability.
In addition, the operation of our packaging and testing facilities is subject to a number of risks, including the following:
unavailability of equipment, whether new or previously owned, at acceptable terms and prices;
facility equipment failure, power outages or other disruptions;
shortage of raw materials, including packaging substrates, copper, gold and molding compound;
failure to maintain quality assurance and remedy defects and impurities;
changes in the packaging requirements of customers; and
our limited experience in operating a high-volume packaging and testing facility.

18


 Any of the foregoing risks could adversely affect our capacity to package and test our products, which could delay shipment of our products, result in higher expenses, reduce revenue, damage our relationships with customers and otherwise adversely affect our business, results of operations, financial condition and prospects.
Our reliance on distributors to sell a substantial portion of our products subjects us to a number of risks.
We sell a substantial portion of our products to distributors, who in turn sell to our end customers. Our distributors typically offer power semiconductor products from several different companies, including our direct competitors. The distributors assume collection risk and provide logistical services to end customers, including stocking our products. Two distributors, WPG and Promate, collectively accounted for 64.7%, 66.0% and 64.9% of our revenue for the fiscal years ended June 30, 2014, 2013 and 2012, respectively. Our agreement with Frontek Technology Corporation, a member of WPG, has an one-year term but is automatically renewed for an additional one-year period continuously unless terminated earlier pursuant to the provisions in the agreement. Our agreement with Promate was renewed in July 2010 with a five-year term and thereafter will be automatically renewed for each one-year period continuously unless terminated earlier pursuant to the provisions in the agreement. We believe that our success will continue to depend upon these distributors. Our reliance on distributors subjects us to a number of risks, including:
write-downs in inventories associated with stock rotation rights and increases in provisions for price adjustments granted to certain distributors;
potential reduction or discontinuation of sales of our products by distributors;
failure to devote resources necessary to sell our products at the prices, in the volumes and within the time frames that we expect;
focusing their sales efforts on products of our competitors;
dependence upon the continued viability and financial resources of these distributors, some of which are small organizations with limited working capital and all of which depend on general economic conditions and conditions within the semiconductor industry;
dependence on the timeliness and accuracy of shipment forecasts and resale reports from our distributors;
management of relationships with distributors, which can deteriorate as a result of conflicts with efforts to sell directly to our end customers; and
termination of our agreements with distributors which are generally terminable by either party on short notice.
If any significant distributor becomes unable or unwilling to promote and sell our products, or if we are not able to renew our contracts with the distributors on acceptable terms, we may not be able to find a replacement distributor on reasonable terms or at all and our business could be harmed.

We have made and may continue to make strategic acquisitions of other companies, assets or businesses and these acquisitions introduce significant risks and uncertainties, including risks related to integrating the acquired assets or businesses, incurring additional debt, assuming contingent liabilities or diluting our existing shareholders.

In order to position ourselves to take advantage of growth opportunities, we have made, and may continue to make, strategic acquisitions, mergers and alliances that involve significant risks and uncertainties. Successful acquisitions and alliances in the semiconductor industry are difficult to accomplish because they require, among other things, efficient integration and aligning of product offerings and manufacturing operations and coordination of sales and marketing and research and development efforts. The difficulties of integration and alignment may be increased by the necessity of coordinating geographically separated organizations, the complexity of the technologies being integrated and aligned and the necessity of integrating personnel with disparate business backgrounds and combining different corporate cultures.

In addition, we may also issue equity securities to pay for future acquisitions or alliances, which could be dilutive to existing shareholders. We may also incur debt or assume contingent liabilities in connection with acquisitions and alliances, which could impose restrictions on our business operations and harm our operating results.
If we are unable to obtain raw materials in a timely manner or if the price of raw materials increases significantly, production time and product costs could increase, which may adversely affect our business.

Our fabrication and packaging processes depend on raw materials such as silicon wafers, gold, copper, molding compound, petroleum and plastic materials and various chemicals and gases. From time to time, suppliers may extend lead

19


times, limit supplies or increase prices due to capacity constraints or other factors. If the prices of these raw materials rise significantly, we may be unable to pass on the increased cost to our customers. Our results of operations could be adversely affected if we are unable to obtain adequate supplies of raw materials in a timely manner or at reasonable price. In addition, from time to time, we may need to reject raw materials because they do not meet our specifications or the sourcing of such materials do not comply with our conflict mineral policies, resulting in potential delays or declines in output. Furthermore, problems with our raw materials may give rise to compatibility or performance issues in our products, which could lead to an increase in customer returns or product warranty claims. Errors or defects may arise from raw materials supplied by third parties that are beyond our detection or control, which could lead to additional customer returns or product warranty claims that may adversely affect our business and results of operations.
Our operations may be delayed or interrupted and our business may be adversely affected as a result of our efforts to comply with environmental regulations applicable to our in-house wafer manufacturing, packaging and testing facility.
Our in-house manufacturing operations, including wafer manufacturing, packaging and testing, are subject to a variety of environmental regulations relating to the use, handling, discharge and disposal of toxic or otherwise hazardous materials. See “Item 1. Business - Environmental matters.” Compliance with environmental regulations could require us to acquire expensive pollution control equipment or to incur other substantial expenses or investigate and remediate contamination at our current facilities. Any failure, or any claim that we have failed, to comply with these regulations could cause delays in our production and capacity expansion and affect our public image, either of which could harm our business. In addition, any failure to comply with these regulations could subject us to substantial fines or other liabilities, result in the suspension of our operating permit, or require us to terminate or adversely modify our in-house manufacturing operations.
We may not be able to accurately estimate provisions at fiscal period end for price adjustment and stock rotation rights under our agreements with distributors, and our failure to do so may impact our operating results.
We sell a majority of our products to distributors under arrangements allowing price adjustments and returns under stock rotation programs, subject to certain limitations. As a result, we are required to estimate allowances for price adjustments and stock rotation for our products as inventory at distributors at each reporting period end. Our ability to reliably estimate these allowances enables us to recognize revenue upon delivery of goods to distributors instead of upon resale of goods by distributors to end customers.
We estimate the allowance for price adjustment based on factors such as distributor inventory levels, pre-approved future distributor selling prices, distributor margins and demand for our products. Our estimated allowances for price adjustments, which we offset against accounts receivable from distributors, were $14.6 million and $13.2 million at June 30, 2014 and 2013, respectively.
Our accruals for stock rotation are estimated based on historical returns and individual distributor agreement, and stock rotation rights, which are recorded as accrued liabilities on our consolidated balance sheets, are contractually capped based on the terms of each individual distributor agreement. Our estimated liabilities for stock rotation at June 30, 2014 and 2013 were both $1.6 million.
Our estimates for these allowances and accruals may be inaccurate. If we subsequently determine that any allowance and accrual based on our estimates is insufficient, we may be required to increase the size of our allowances and accrual in future periods, which would adversely affect our results of operations and financial condition.
We depend on the continuing efforts of our senior management team and other key personnel, and if we lose a member of our senior management or are unable to successfully retain, recruit and train key personnel, our ability to develop and market our products could be harmed.
Our success depends upon the continuing services of members of our senior management team and various engineering and other technical personnel. In particular, our engineers and other sales and technical personnel are critical to our future technological and product innovations. Our industry is characterized by high demand and intense competition for talent and the pool of qualified candidates is limited. We have entered into employment agreements with certain senior executives, but we do not have employment agreements with most of our employees. Many of these employees could leave our company with little or no prior notice and would be free to work for a competitor. If one or more of our senior executives or other key personnel are unable or unwilling to continue in their present positions, we may not be able to replace them easily or at all and other senior management may be required to divert attention from other aspects of our business. In addition, we do not have “key person” life insurance policies covering any member of our management team or other key personnel. The loss of any of these individuals or our inability to attract or retain qualified personnel, including engineers and others, could adversely affect our product introductions, overall business growth prospects, results of operations and financial condition.

20


If we fail to maintain an effective system of internal control over financial reporting, we may not be able to accurately report our financial results or prevent fraud.
Our management may conclude that our internal control over financial reporting is not effective. Moreover, even if our management concludes that our internal control over financial reporting is effective, our independent registered public accounting firm may decline to issue an opinion as to the effectiveness of our internal control over financial reporting, or may issue a report that is qualified or adverse. During the course of the initial evaluation of internal control over financial reporting, we or our independent registered public accounting firm may identify control deficiencies that we may not be able to remediate prior to the date of our first assessment of internal control over financial reporting. Our failure to achieve and maintain effective internal control over financial reporting could result in the loss of investor confidence in the reliability of our financial statements or prevent fraud, which in turn could harm our business and negatively impact the trading price of our shares.
Failure to protect our patents and our other proprietary information could harm our business and competitive position.
Our success depends, in part, on our ability to protect our intellectual property. We rely on a combination of patent, copyright (including mask work protection), trademark and trade secret laws, as well as nondisclosure agreements, license agreements and other methods to protect our intellectual property rights, which may not be sufficient to protect our intellectual property. As of June 30, 2014, we owned 420 issued U.S. patents expiring between 2015 and 2032 and had 213 pending patent applications with the United States Patent and Trademark Office. In addition, we own additional patents and have filed patent applications in several jurisdictions outside of the U.S, including China, Taiwan, Japan and Korea.
 Our patents and patent applications may not provide meaningful protection from our competitors, and there is no guarantee that patents will be issued from our patent applications. The status of any patent or patent application involves complex legal and factual determinations and the breadth of a claim is uncertain. In addition, our efforts to protect our intellectual property may not succeed due to difficulties and risks associated with:
policing any unauthorized use of or misappropriation of our intellectual property, which is often difficult and costly and could enable third parties to benefit from our technologies without paying us;
others independently developing similar proprietary information and techniques, gaining authorized or unauthorized access to our intellectual property rights, disclosing such technology or designing around our patents;
the possibility that any patent or registered trademark owned by us may not be enforceable or may be invalidated, circumvented or otherwise challenged in one or more countries and the rights granted thereunder may not provide competitive advantages to us;
uncertainty as to whether patents will be issued from any of our pending or future patent applications with the scope of the claims sought by us, if at all; and
intellectual property laws and confidentiality protections, which may not adequately protect our intellectual property rights, including, for example, in China where enforcement of China intellectual property-related laws has historically been ineffective, primarily because of difficulties in enforcement and low damage awards.
 We also rely on customary contractual protections with our customers, suppliers, distributors, employees and consultants, and we implement security measures to protect our trade secrets. We cannot assure you that these contractual protections and security measures will not be breached, that we will have adequate remedies for any such breach or that our suppliers, employees, distributors or consultants will not assert rights to intellectual property arising out of such contracts.
In addition, we have a number of third-party patent and intellectual property license agreements, one of which requires us to make ongoing royalty payments. In the future, we may need to obtain additional licenses, renew existing license agreements or otherwise replace existing technology. We are unable to predict whether these license agreements can be obtained or renewed or the technology can be replaced on acceptable terms, or at all.
Intellectual property disputes could result in lengthy and costly arbitration, litigation or licensing expenses or prevent us from selling our products.
As is typical in the semiconductor industry, we or our customers may receive claims of infringement from time to time or otherwise become aware of potentially relevant patents or other intellectual property rights held by other parties that may cover some of our technology, products and services or those of our end customers. The semiconductor industry is characterized by vigorous protection and pursuit of intellectual property rights which has resulted in protracted and expensive arbitration and litigation for many companies. Patent litigation has increased in recent years due to increased assertions made

21


by intellectual property licensing entities or non-practicing entities and increasing competition and overlap of product functionality in our markets.

Any litigation or arbitration regarding patents or other intellectual property could be costly and time consuming and could divert our management and key personnel from our business operations. We have in the past and may from time to time in the future become involved in litigation that requires our management to commit significant resources and time. In addition, as part of our strategy to diversify our serviceable markets, we launched several key product families and technologies to enable high efficiency power conversion solutions and we plan to develop and commercialize new products in other power semiconductor markets. Our entry into the commercial markets for high-voltage power semiconductors and other markets as a result of our diversification strategy may subject us to additional and increased risk of disputes or litigation relating to these products.
Because of the complexity of the technology involved and the uncertainty of litigation generally, any intellectual property arbitration or litigation involves significant risks. Any claim of intellectual property infringement against us may require us to:
Incur substantial legal and personnel expenses to defend the claims or to negotiate for a settlement of claims;
pay substantial damages or settlement to the party claiming infringement;
refrain from further development or sale of our products;
attempt to develop non-infringing technology, which may be expensive and time consuming, if possible at all;
enter into costly royalty or license agreements that might not be available on commercially reasonable terms or at all;
cross-license our technology with a competitor to resolve an infringement claim, which could weaken our ability to compete with that competitor; and
indemnify our distributors, end customers, licensees and others from the costs of and damages of infringement claims by our distributors, end customers, licensees and others, which could result in substantial expenses for us and damage our business relationships with them.
Any intellectual property claim or litigation could harm our business, results of operations, financial condition and prospects.
Global or regional economic, political and social conditions could adversely affect our business and operating results.
External factors such as potential terrorist attacks, acts of war, financial crises, such as the global or regional economic recession, or geopolitical and social turmoil in those parts of the world that serve as markets for our products could have significant adverse effect on our business and operating results in ways that cannot presently be predicted. Any future economic downturn or recession in the global economy in general and, in particular, on the economies in China, Taiwan and other countries where we market and sell our products, will have an adverse effect on our results of operations. Recently, we experienced a significant reduction in the demand for our products due to the declining PC markets, particularly from our distributors and customers in Taiwan, which have negatively impacted our revenue and profitability.
Our business operations could be significantly harmed by natural disasters or global epidemics.
We have research and development facilities located in Taiwan and the Silicon Valley in Northern California. Historically, these regions have been vulnerable to natural disasters and other risks, such as earthquakes, fires and floods, which may disrupt the local economy and pose physical risks to our property. We also have sales offices located in Taiwan and Japan where similar natural disasters and other risks may disrupt the local economy and pose physical risks to our operations. We are not currently covered by insurance against business disruption caused by earthquakes. In addition, we currently do not have redundant, multiple site capacity in the event of a natural disaster or other catastrophic event. In the event of such an occurrence, our business would suffer.

Our business could be adversely affected by natural disasters such as epidemics, outbreaks or other health crisis. An outbreak of avian flu or H1N1 flu in the human population, or another similar health crisis, could adversely affect the economies and financial markets of many countries, particularly in Asia. Moreover, any related disruptions to transportation or the free movement of persons could hamper our operations and force us to close our offices temporarily.
The occurrence of any of the foregoing or other natural or man-made disasters could cause damage or disruption to us, our employees, operations, distribution channels, markets and customers, which could result in significant delays in deliveries

22


or substantial shortages of our products and adversely affect our business results of operations, financial condition or prospects.
Our insurance may not cover all losses, including losses resulting from business disruption or product liability claims.
We have limited product liability, business disruption or other business insurance coverage for our operations. In addition, we do not have any business insurance coverage for our operations to cover losses that may be caused by litigation or natural disasters. Any occurrence of uncovered loss could harm our business, results of operations, financial condition and prospects.

We may be adversely affected by any disruption in our information technology systems.

Our operations are dependent upon our information technology systems, which encompass all of our major business functions across offices internationally. We rely upon such information technology systems to manage and replenish inventory, complete and track customer orders, coordinate sales activities across all of our products and services, maintain vital data and information, perform financial and accounting tasks and manage and perform various administrative and human resources functions. A substantial disruption in our information technology systems for any extended time period (arising from, for example, system capacity limits from unexpected increases in our volume of business, outages or delays in our service) could result in delays in receiving inventory and supplies or filling customer orders and adversely affect our customer service and relationships. Our systems might be damaged or interrupted by natural or man−made events or by computer viruses, physical or electronic break−ins, cyber attacks and similar disruptions affecting the global Internet. There can be no assurance that such delays, problems, or costs will not have a material adverse effect on our cash flows, results of operations and financial condition.
Our international operations subject our company to risks not faced by companies without international operations.
We have adopted a global business model under which we maintain significant operations and facilities through our subsidiaries located in the U.S., China, Taiwan and Hong Kong. Our main research and development center is located in Silicon Valley, and our manufacturing and supply chain is located in China. We also have sales offices and customers throughout Asia, the U.S. and elsewhere in the world. The following are some of the risks inherent in doing business on an international level that may not be applicable to domestic companies:
economic and political instability;
costs and delays associated with transportations and communications;
coordination of operations through multiple jurisdictions and time zones;
fluctuations in foreign currency exchange rates;
trade restrictions, changes in laws and regulations relating to, amongst other things, import and export tariffs, taxation, environmental regulations, land use rights and property; and
the laws of, including tax laws, and the policies of the U.S. toward, countries in which we operate.
 
We are subject to the risk of increased income taxes and changes in existing tax rules.

We conduct our business in multiple jurisdictions, including Hong Kong, Macau, the U.S., China, Taiwan, South Korea and Japan. Any of these jurisdictions may assert that we have unpaid taxes. Our effective tax rates have fluctuated significantly in recent years. Our effective tax rate was (887.5)%, (254.2)% and 21.7% for the fiscal years ended June 30, 2014, 2013 and 2012, respectively. Any tax rate changes in the tax jurisdictions in which we operate could result in adjustments to our deferred tax assets, if applicable, which would affect our effective tax rate and results of operations. We base our tax position upon the anticipated nature and conduct of our business and upon our understanding of the tax laws of the various countries in which we have assets or conduct activities. However, our tax position is subject to review and possible challenge by tax authorities and to possible changes in law, which may have a retroactive effect. In particular, various proposals over the years have been made to change certain U.S. tax laws relating to foreign entities with U.S. connections. In addition, the U.S. government has proposed various other changes to the U.S. international tax system, certain of which could adversely impact foreign-based multinational corporate groups, and increased enforcement of U.S. international tax laws. It is possible that these or other changes in the U.S. tax laws or proposed actions by international bodies such as the Organization of Economic Cooperation and Development (OECD) could significantly increase our U.S. or foreign income tax liability in the future.


23


In addition, our subsidiaries provide products and services to, and may from time to time undertake certain significant transactions with, us and other subsidiaries in different jurisdictions. We have adopted transfer pricing arrangements for transactions among our subsidiaries. Related party transactions are generally subject to close review by tax authorities, including requirements that transactions be priced at arm's length and be adequately documented. If any tax authorities were successful in challenging our transfer pricing policies or other tax judgments, our income tax expense may be adversely affected and we could also be subject to interest and penalty charges which may harm our business, financial condition and operating results.

The imposition of U.S. corporate income tax on our Bermuda parent and non-U.S. subsidiaries could adversely affect our results of operations.

We believe that our Bermuda parent and non-U.S. subsidiaries each operate in a manner that they would not be subject to U.S. corporate income tax because they are not engaged in a trade or business in the United States. Nevertheless, there is a risk that the U.S. Internal Revenue Service may successfully assert that our Bermuda parent and non-U.S. subsidiaries are engaged in a trade or business in the United States. If our Bermuda parent and non-U.S. subsidiaries were characterized as being so engaged, we would be subject to U.S. tax at regular corporate rates on our income that is effectively connected with U.S. trade or business, plus an additional 30% “branch profits” tax on the dividend equivalent amount, which is generally effectively connected income with certain adjustments, deemed withdrawn from the United States. Any such tax could materially and adversely affect our results of operations.

We may be classified as a passive foreign investment company, which could result in adverse U.S. federal income tax consequences for U.S. holders.

Based on the current and anticipated valuation of our assets and the composition of our income and assets, we do not expect to be considered a passive foreign investment company, or PFIC, for U.S. federal income tax purposes for the foreseeable future. However, we must make a separate determination for each taxable year as to whether we are a PFIC after the close of each taxable year and we cannot assure you that we will not be a PFIC for our 2014 taxable year or any future taxable year. Under current law, a non-U.S. corporation will be considered a PFIC for any taxable year if either (1) at least 75% of its gross income is passive income or (2) at least 50% of the value of its assets, generally based on an average of the quarterly values of the assets during a taxable year, is attributable to assets that produce or are held for the production of passive income. PFIC status depends on the composition of our assets and income and the value of our assets, including, among others, a pro rata portion of the income and assets of each subsidiary in which we own, directly or indirectly, at least 25% by value of the subsidiary's equity interests, from time to time. Because we currently hold and expect to continue to hold a substantial amount of cash or cash equivalents, and because the calculation of the value of our assets may be based in part on the value of our common shares, which may fluctuate considerably given that market prices of technology companies historically often have been volatile, we may be a PFIC for any taxable year. If we were treated as a PFIC for any taxable year during which a U.S. holder held common shares, certain adverse U.S. federal income tax consequences could apply for such U.S. holder.

Risks Related to Our Industry
The average selling prices of products in our markets have historically decreased rapidly and will likely do so in the future, which could harm our revenue and gross margins.
As is typical in the semiconductor industry, the average selling price of a particular product has historically declined significantly over the life of the product. In the past, we have reduced the average selling prices of our products in anticipation of future competitive pricing pressures, new product introductions by us or our competitors and other factors. We expect that we will have to similarly reduce prices in the future for older generations of products. Reductions in our average selling prices to one customer could also impact our average selling prices to all customers. A decline in average selling prices would harm our gross margins for a particular product. If not offset by sales of other products with higher gross margins, our overall gross margins may be adversely affected. Our business, results of operations, financial condition and prospects will suffer if we are unable to offset any reductions in our average selling prices by increasing our sales volumes, reducing our costs and developing new or enhanced products on a timely basis, with higher selling prices or gross margins.
We may be adversely affected by the cyclicality of the semiconductor industry.
Our industry is highly cyclical and is characterized by constant and rapid technological change such as the introduction of smartphones and tablets that contributed to the decline in the PC market, product obsolescence and price erosion, evolving

24


standards, uncertain product life cycles and wide fluctuations in product supply and demand. The industry has, from time to time, experienced significant and sometimes prolonged, downturns, and often connected with or in anticipation of, maturing product cycles and declines in general economic conditions. These downturns have been characterized by diminished product demand, production overcapacity, high inventory levels and accelerated erosion of average selling prices. Any future downturns, in particular the PC markets, may reduce our revenue and result in us having excess inventory. By contrast, any upturn in the semiconductor industry could result in increased competition for access to limited third-party foundry and packaging and testing capacity, which could prevent us from benefiting from such an upturn or reduce our profit margins.
Changes in industry standards, technology, customer requirements and government regulation could limit our ability to sell our products.
The semiconductor industry is characterized by changing demand for new and advanced functions, long design and sales cycles, rapid product obsolescence and price erosion, intense competition, evolving industry standards and wide fluctuations in product supply and demand. Changes in industry standards, or the development of new industry standards, or, when applicable, government approval or disapproval of industry standards may make our products obsolete or negate the cost advantages we believe we have in our products. We may be required to invest significant effort and to incur significant expense to redesign our products in order to address relevant standards, technological developments, customer requirements or regulations but may not have the financial resources to respond to these changes effectively or in a timely manner. Any inability to meet these standards, regulations and requirements could harm our business, results of operations, financial condition and prospects.
Risks Related to Doing Business in China
China's economic, political and social conditions, as well as government policies, could affect our business and growth.
Our financial results have been, and are expected to continue to be, affected by the economy in China. A slowdown of economic growth in China or other adverse developments could harm our business, results of operations, financial condition and prospects.
The China economy differs from the economies of most developed countries in many respects, including:
higher level of government involvement;
early stage of development of a market-oriented economy;
rapid growth rate;
higher level of control over foreign currency exchange; and
less efficient allocation of resources.
 The Chinese economy has been transitioning from a planned economy to a more market-oriented economy. Although in recent years the China government has implemented measures emphasizing the utilization of market forces for economic reform, the reduction of state ownership of productive assets and the establishment of corporate governance in business enterprises, the China government continues to retain significant control over the business and productive assets in China. Any changes in China's government policy or China's political, economic and social conditions, or in relevant laws and regulations, may adversely affect our current or future business, results of operation or financial condition. These changes in government policy may be implemented through various means, including changes in laws and regulations, implementation of anti-inflationary measures, changes in the tax rate or taxation system and the imposition of additional restrictions on currency conversion and imports. Furthermore, given China's largely export-driven economy, any changes in the economies of the China's principal trading partners and other export-oriented nations may adversely affect our business, results of operations, financial condition and prospects.
Our ability to successfully expand our business operations in China depends on a number of factors, including macroeconomic and other market conditions, and credit availability from lending institutions. In response to the recent global and Chinese economic recession, the China government has promulgated several measures aimed at expanding credit and stimulating economic growth. We cannot assure you that the various macroeconomic measures, monetary policies and economic stimulus package adopted by the China government to guide economic growth will be effective in maintaining or sustaining the growth rate of the Chinese economy. If measures adopted by the China government fail to achieve further growth in the Chinese economy, it may adversely affect our growth, business strategies and operating results. In addition, changes in political and social conditions of China may adversely affect our ability to conduct our business in the region. For

25


example, geopolitical disputes and increased tensions between China and its neighboring countries in which we conduct business could make it more difficult for us coordinate and manage our international operations in such countries.
Changes in China's laws, legal protections or government policies on foreign investment in China may harm our business.
Our business and corporate transactions are subject to laws and regulations applicable to foreign investment in China as well as laws and regulations applicable to foreign-invested enterprises. These laws and regulations frequently change, and their interpretation and enforcement involves uncertainties that could limit the legal protections available to us. Regulations and rules on foreign investments in China impose restrictions on the means that a foreign investor like us may apply to facilitate corporate transactions we may undertake. In addition, the Chinese legal system is based in part on government policies and internal rules, some of which are not published on a timely basis or at all, that may have a retroactive effect. As a result we may not be aware of our violation of these policies and rules until some time after the violation. If any of our past operations are deemed to be non-compliant with Chinese law, we may be subject to penalties and our business and operations may be adversely affected. For instance, under the catalogue for the Guidance of Foreign Investment Industries, some industries are categorized as sectors which are encouraged, restricted or prohibited for foreign investment. As the catalogue for the Guidance of Foreign Investment Industries is updated every few years, there can be no assurance that the China government will not change its policies in a manner that would render part or all of our business to fall within the restricted or prohibited categories. If we cannot obtain approval from relevant authorities to engage in businesses which become prohibited or restricted for foreign investors, we may be forced to sell or restructure a business which has become restricted or prohibited for foreign investment. Furthermore, the China government has broad discretion in dealing with violations of laws and regulations, including levying fines, revoking business and other licenses and requiring actions necessary for compliance. In particular, licenses and permits issued or granted to us by relevant governmental bodies may be revoked at a later time by higher regulatory bodies. If we are forced to adjust our corporate structure or business as a result of changes in government policy on foreign investment or changes in the interpretation and application of existing or new laws, our business, financial condition, results of operations and prospects may be harmed. Moreover, uncertainties in the Chinese legal system may impede our ability to enforce contracts with our business partners, customers and suppliers, or otherwise pursue claims in litigation to recover damages or loss of property, which could adversely affect our business and operations.
Limitations on our ability to transfer funds to our China subsidiaries could adversely affect our ability to expand our operations, make investments that could benefit our businesses and otherwise fund and conduct our business.
The transfer of funds from us to our China subsidiaries, either as a shareholder loan or as an increase in registered capital, is subject to registration with or approval by the China's governmental authorities, including the State Administration of Foreign Exchange, or SAFE, or the relevant examination and approval authority. Our subsidiaries may also experience difficulties in converting our capital contributions made in foreign currencies into RMB due to changes in the China's foreign exchange control policies. Therefore, it may be difficult to change capital expenditure plans once the relevant funds have been remitted from us to our China subsidiaries. These limitations and the difficulties our China subsidiaries may experience on the free flow of funds between us and our China subsidiaries could restrict our ability to act in response to changing market situations in a timely manner.
China's currency exchange control and government restrictions on investment repatriation may impact our ability to transfer funds outside of China.
A significant portion of our business is conducted in China where the currency is the Renminbi. Regulations in China permit foreign owned entities to freely convert the Renminbi into foreign currency for transactions that fall under the “current account,” which includes trade related receipts and payments, interest and dividends. Accordingly, our Chinese subsidiaries may use Renminbi to purchase foreign exchange for settlement of such “current account” transactions without pre-approval. However, pursuant to applicable regulations, foreign‑invested enterprises in China may pay dividends only out of their accumulated profits, if any, determined in accordance with Chinese accounting standards and regulations. In calculating accumulated profits, foreign investment enterprises in China are required to allocate at least 10% of their accumulated profits each year, if any, to fund certain reserve funds, including mandated employee benefits funds, unless these reserves have reached 50% of the registered capital of the enterprises.
Other transactions that involve conversion of Renminbi into foreign currency are classified as “capital account” transactions; examples of “capital account” transactions include repatriations of investment by or loans to foreign owners, or direct equity investments in a foreign entity by a China domiciled entity. “Capital account” transactions require prior approval from China's State Administration of Foreign Exchange (SAFE) or its provincial branch to convert a remittance into a foreign currency, such as U.S. dollars, and transmit the foreign currency outside of China.

26


As a result of these and other restrictions under PRC laws and regulations, our China subsidiaries are restricted in their ability to transfer a portion of their net assets to the parent; such restricted portion amounted to approximately $85.6 million, or 30.3% of our total consolidated net assets as of June 30, 2014. We have no assurance that the relevant Chinese governmental authorities in the future will not limit further or eliminate the ability of our China subsidiaries to purchase foreign currencies and transfer such funds to us to meet our liquidity or other business needs. Any inability to access funds in China, if and when needed for use by the Company outside of China, could have a material and adverse effect on our liquidity and our business.

Our result of operations may be negatively impacted by fluctuations in foreign currency exchange rates between U.S. dollars and Chinese Yuan, or RMB.
    
While U.S. dollars is our main functional currency and our revenue and a significant portion of our operating expenses are denominated in U.S. dollars, we are required to maintain local currencies, primarily the RMB, in our cash balances in connection with the funding of our oversea operations.   As a result, our costs and operating expenses may be exposed to adverse movements in foreign currency exchange rates between the U.S. dollars and RMB.  We also do not utilize any financial instruments to hedge or reduce potential losses due to the fluctuation of foreign currency exchange rates.  In general, any appreciation of U.S. dollars against a weaker RMB could reduce the value of our cash and cash equivalent balance, which could increase our operating expenses and negatively affect our cash flow, income and profitability.  The value of RMB against the U.S. dollars may fluctuate and is affected by many factors outside of our control, including changes in political and economic conditions, implementation of new monetary policies by the Chinese government and changes in banking regulations, and there is no guarantee that we will be able to mitigate or recoup any losses due to a significant fluctuation in the U.S. dollars/RMB exchange rates.
Controversies affecting China's trade with the United States could harm our business.
While China has been granted permanent most favored nation trade status in the United States through its entry into the World Trade Organization, controversies between the United States and China may arise that threaten the trading relationship between the two countries. At various times during recent years, the United States and China have had disagreements over political and economic issues. In addition, disagreements between the United States and China with respect to their political, military or economic policies toward Taiwan may contribute to further controversies. These controversies and trade frictions could have a material adverse effect on our business by, among other things, making it more difficult for us to coordinate our operations between the United States and China or causing a reduction in the demand for our products by customers in the United States or China.
Relations between Taiwan and China could negatively affect our business, financial condition and operating results and, therefore, the market value of our common shares.
Taiwan has a unique international political status. China does not recognize the sovereignty of Taiwan. Although significant economic and cultural relations have been established during recent years between Taiwan and China, relations have often been strained. A substantial number of our key customers and some of our essential sales and engineering personnel are located in Taiwan, and we have a large number of operational personnel and employees located in China. Therefore, factors affecting military, political or economic relationship between China and Taiwan could have an adverse effect on our business, financial condition and operating results.
Risks Related to Our Corporate Structure and Our Common Shares
Our share price may be volatile and you may be unable to sell your shares at or above the purchase price, if at all.

Limited trading volumes and liquidity of our common shares on The NASDAQ Global Market may limit the ability of shareholders to purchase or sell our common shares in the amounts and at the times they wish.  In addition, the financial markets in the United States and other countries have experienced significant price and volume fluctuations, and market prices of technology companies have been and continue to be extremely volatile. The trading price of our common shares on The NASDAQ Global Market ranged from a low of $6.83 to high of $17.91 from the commencement of the public trading of our common shares on April 29, 2010, to July 31, 2014 and from a low of $6.83 to high of $9.30 from July 1, 2013 to June 30, 2014. Volatility in the price of our shares may be caused by factors outside our control and may be unrelated or disproportionate to our operating results.
The market price for our common shares may be volatile and subject to wide fluctuations in response to factors, including:

27


actual or anticipated fluctuations in our operating results;
general economic, industry, regional and global market conditions, including the economic conditions of specific market segments for our products, including the PC markets;
our failure to meet analysts' expectations, including expectation regarding our revenue, gross margin and operating expenses;
changes in financial estimates and outlook by securities research analysts;
our ability to increase our gross margin;
announcements by us or our competitors of new products, acquisitions, strategic partnerships, joint ventures or capital commitments;
announcements of technological or competitive developments;
announcement of acquisition and major corporate transactions;
regulatory developments in our target markets affecting us, our customers or our competitors;
our ability to enter into new market segments, gain market share, diversify our customer base and successfully secure manufacturing capacity;
announcements regarding intellectual property disputes or litigation involving us or our competitors;
changes in the estimation of the future size and growth rate of our markets;
additions or departures of key personnel;
announcement of sales of our securities by us or by our major shareholders;
general economic or political conditions in China; and
other factors.
  In the past, securities class action litigation has often been brought against a company following periods of volatility in such company's share price.  This type of litigation could result in substantial costs and divert our management's attention and resources which could negatively impact our business and financial conditions.
If securities or industry analysts do not publish research or reports about our business, or if they adversely change their recommendations regarding our common shares or if our operating results do not meet their expectations, the trading price of our common shares could decline.

The market price of our common shares is influenced by the research and reports that industry or securities analysts publish about us or our business. There is no guarantee that these analysts will understand our business and results, or that their reports will be accurate or correctly predict our operating results or prospects. If one or more of these analysts cease coverage of our company or fail to publish reports on us regularly, we could lose visibility in the financial markets, which in turn could cause the market price of our common shares or its trading volume to decline. Moreover, if one or more of the analysts who cover our company downgrade our common shares or if our operating results or prospects do not meet their expectations, the market price of our common shares could decline significantly.
Anti-takeover provisions in our bye-laws could make an acquisition of us more difficult and may prevent attempts by our shareholders to replace or remove our current management.
Certain provisions in our bye-laws may delay or prevent an acquisition of us or a change in our management. In addition, by making it more difficult for shareholders to replace members of our board of directors, these provisions also may frustrate or prevent any attempts by our shareholders to replace or remove our current management because our board of directors is responsible for appointing the members of our management team. These provisions include:
the ability of our board of directors to determine the rights, preferences and privileges of our preferred shares and to issue the preferred shares without shareholder approval;
advance notice requirements for election to our board of directors and for proposing matters that can be acted upon at shareholder meetings; and
the requirement to remove directors by a resolution passed by at least two-thirds of the votes cast by the shareholders having a right to attend and vote at the shareholder meeting.

28


These provisions could make it more difficult for a third-party to acquire us, even if the third-party's offer may be considered beneficial by many shareholders. As a result, shareholders may be limited in their ability to obtain a premium for their shares.
Insiders have substantial control over us, which could adversely affect the market price of our shares.
Our Chief Executive Officer, certain members of our management and directors, beneficially owned, in the aggregate, approximately 20% of our outstanding common shares as of June 30, 2014. As a result, these shareholders will be able to exert significant control over all matters requiring shareholder approval, including the election of directors and approval of significant corporate transactions, such as a merger, consolidation, takeover or other business combination involving us. This concentration of ownership may also discourage, delay or prevent a change in control of our company, which could deprive our shareholders of an opportunity to receive a premium for their shares as part of a sale of our company and may reduce the trading price of our shares. Furthermore, the interests of these insiders could conflict with the interests of our other shareholders and, accordingly, any of them may take actions that favor their own interests and which may not be in the best interests of our other shareholders. These actions may be taken even if they are opposed by our other shareholders.

Share Performance Graph
The following graph compares the total cumulative shareholder return on our common shares with the total cumulative return of the NASDAQ Composite Index and the Philadelphia Semiconductor Index for the period from April 29, 2010 (the date our common share commenced trading on the NASDAQ Global Market) through June 30, 2014, the end of our last fiscal year. The graph assumes an investment of $100 on April 29, 2010 and the reinvestment of any dividends for NASDAQ Composite Index and Philadelphia Semiconductor Index.
The comparisons in the graph below are required by the SEC and are not intended to forecast or be indicative of possible future performance of our common shares.
The above Stock Performance Graph and related information shall not be deemed “soliciting material” or to be “filed” with the Securities and Exchange Commission, nor shall such information be incorporated by reference into any future filing under the Securities Act of 1933 or Securities Exchange Act of 1934, each as amended, except to the extent that the Company specifically incorporates it by reference into such filing.

Purchases of Equity Securities by the Issuer and Affiliated Purchasers
On May 8, 2014, our Board of Directors approved to reactivate the share repurchase program which was originally authorized on October 22, 2010 for a total amount of $25.0 million. The Board authorized management to repurchase, subject to oversight by the Board, our common shares up to the remaining balance of the program, or $22.7 million. The repurchases may be made from the open market or through negotiated block transactions and to date repurchases have been made pursuant to a pre-established 10b5-1 trading plan. Such 10b5-1 trading plan was expired in August 2014 and the Board intends to review conditions from time to time to determine whether it is appropriate to implement a new 10b5-1 trading plan or to conduct repurchases under the program outside of a 10b5-1 trading plan. The amount and timing of any purchases will depend on a number of factors, including but not limited to the price and availability of our common shares, trading volume of our common shares, applicable regulatory requirements, our business and financial conditions and general market environment, and there is no guarantee that any repurchases will be made or that such repurchases may enhance the value of our shares. Shares repurchased are accounted for as treasury shares and the total cost of shares repurchased is recorded as a reduction to shareholders' equity. The following table sets for the share repurchases under this program during the fiscal quarter ended June 30, 2014.

We held a 40.3% equity interest in APM at June 30, 2010. We made an additional equity investment of $1.8 million in APM in October 2010 and held a 43% equity interest in APM immediately prior to the APM acquisition. The investment was accounted for under the equity method of accounting. On December 3, 2010, we acquired all of the outstanding shares of APM and APM's operating results were included in our consolidated financial statements since the date of the acquisition.
(2)
Upon the completion of the APM acquisition in fiscal year 2011, we performed a review and assessment of the useful lives of certain of our property and equipment. As a result of our review, we revised the estimated useful life of the related manufacturing machinery and equipment from 5 years to 8 years beginning December 1, 2010 on a prospective basis. The effect of this accounting change was to decrease depreciation expense related to cost of goods sold by $5.1 million, increase net income by approximately $3.9 million, net of a tax effect of $1.2 million, and increase basic net income per share by approximately $0.17 and increase diluted net income per share by approximately $0.16 for fiscal year 2011.
Conversion from International Financial Reporting Standards ("IFRS") to U.S. GAAP
We formerly prepared our consolidated financial statements under IFRS and filed our IFRS financial statements for the fiscal year ended June 30, 2010 in our annual report on Form 20-F. Pursuant to SEC requirements, we assessed our ownership structure as of December 31, 2010 and determined that we no longer qualified as a foreign private issuer under applicable SEC rules. As a result, beginning July 1, 2011, we were required to report our consolidated financial statements under U.S. GAAP and file our annual report on Form 10-K, as well as to comply with additional SEC reporting obligations as a domestic issuer. Accordingly, we have converted our consolidated financial statements under IFRS to U.S. GAAP. A summary of significant relevant differences of individual items in the financial statements between IFRS and U.S. GAAP and their impact to the above historical consolidated financial data for the years ended June 30, 2011 and 2010 is outlined below:
Inventory reserves
We record inventories at the lower-of-cost-or-market under both U.S. GAAP and IFRS. Under U.S. GAAP, a write-down of inventory to the lower-of-cost-or-market creates a new cost basis that subsequently cannot be reversed based on changes in circumstances. Under IFRS, when circumstances that previously caused the inventory write down no longer exist or when there is clear evidence of an increase in net realizable value, the amount of the write-down is reversed even though the associated inventories have not been sold. The impact to the statement of income (loss) due to the difference between U.S. GAAP and IFRS was to increase inventory reserves for the fiscal year ended June 30, 2010 by $100,000.
Share-based compensation expense
Under U.S. GAAP, prior to July 1, 2006, we accounted for options granted to employees using the intrinsic value method as prescribed in Accounting Principles Board (“APB”) Opinion No. 25, "Accounting for Stock Issued to Employees". Under the intrinsic value method, deferred compensation expense is recorded on the date of grant if the fair value of the underlying share exceeds the exercise price, and expense is recognized on a straight-line basis over the vesting period of the grant, generally five years. Effective on July 1, 2006, we adopted ASC Topic 718 (formerly SFAS No. 123R), “Share-Based Payment” using the prospective transition method to account for options granted to employees. Under the prospective method, new awards (or awards modified, repurchased, or canceled after the effective date) are accounted for under the provision of ASC Topic 718, which requires the measurement and recognition of compensation expense for all share-based awards made to employees and directors based on estimated fair values of the awards. We amortize the fair value of options or equity awards using the graded vesting attribution method over the respective vesting period which is generally over five years.

37


Under IFRS, we accounted for share-based compensation expense for all share-based awards made to employees and directors based on the estimated fair values of the awards effective on January 1, 2005. The fair value of options or equity awards is amortized using the graded vesting attribution method over the respective vesting period which is generally over five years.
The increase in share-based compensation expense resulted from the accounting for the different transition dates between U.S. GAAP and IFRS and the application of APB 25 for the fiscal year ended June 30, 2010 was $115,000.
Investment in APM
We have made various investments in APM since APM's inception in July 2004. Prior to our acquisition of APM in December 2010, the investment was accounted for under the equity method of accounting under both IFRS and U.S. GAAP. The changes in income on equity investment in APM resulted from the difference between U.S. GAAP and IFRS for the fiscal year ended June 30, 2010 was $251,000.

Item 7.
Management's Discussion and Analysis of Financial Condition and Results of Operations

You should read the following discussion of the financial condition and results of our operations in conjunction with our consolidated financial statements and the notes to those statements included elsewhere in this annual report. Our consolidated financial statements contained in this annual report are prepared in accordance with U.S. GAAP.
Overview

We are a designer, developer and global supplier of a broad portfolio of power semiconductors. Our portfolio of power semiconductors includes over 1,400 products, and has grown significantly with the introduction of over 150 new products during the fiscal year 2014, and over 195 and 240 new products in the fiscal years 2013 and 2012, respectively. Our teams of scientists and engineers have developed extensive intellectual properties and technical knowledge that encompass major aspects of power semiconductors, which we believe it enables us to introduce and develop innovative products to address the increasingly complex power requirements of advanced electronics. We have an extensive patent portfolio that consists of approximately 420 patents and 213 patent applications in the United States as of June 30, 2014. We differentiate ourselves by integrating our expertise in technology, design and advanced manufacturing and packaging to optimize product performance and cost. Our portfolio of products targets high-volume applications, including personal computers, flat panel TVs, LED lighting, smart phones, battery packs, consumer and industrial motor controls and power supplies for TVs, computers, servers and telecommunications equipment.

During the fiscal year ended June 30, 2014, we continued our diversification program by developing new silicon and packaging platforms to expand our serviceable available market, or SAM and offer higher performance products. Our metal-oxide-semiconductor field-effect transistors, or MOSFET, portfolio expanded significantly across a full range of voltage applications. For example, for the power discrete products, in the September quarter of 2013, we released seven new products in our 600V AlphalGBT portfolio with high efficiency Insulated Gate Bipolar Transistor (IGBT) solutions ranging from 20A to 60A in the TO247 package. These new products are suitable for a wide variety of applications including household appliances, commercial HVAC systems, photovoltaic inverters, and industrial equipment. In addition, in the June quarter of 2014, we released new 1350V IGBT optimized for induction heating applications. The device prevents avalanche destruction from voltage transients. In the December quarter of 2013, we also introduced a new lower voltage dual MOSFET family in the common-drain configuration in both DFN 5x6 and Micro-DFN 3.2x2 packages. These devices are suitable for battery pack applications to enhance battery pack performance in the latest generation Ultrabooks and tablets, where low conduction loss is essential for optimizing battery life. For the power IC products, we continue to expand the product family by introducing new solutions to LED lighting and LED back lighting for LCD-TV. In the September quarter of 2013, we introduced a new generation of high efficiency DrMos power modules. The new device enables higher power density voltage regulator solutions which is ideal for servers, work stations, graphic cards and high-end desktop PC applications. In addition, in the same quarter, we launched a third-generation high efficiency power module with an EZPair package. This new device enables high power density voltage regulator solutions which is ideal for notebook PCs, servers, and graphic cards applications. Moreover, in the June quarter of 2014, we released dual-channel EZPower Smart Load Switch that delivers up to 6A per channel of continuous current. These devices offer industry leading performance and allow the ideal load switch for a variety of applications.
Our business model leverages global resources, including research and development and manufacturing in the United States and Asia. Our sales and technical support teams are localized in several growing markets. We operate a 200mm wafer fabrication facility located in Hillsboro, Oregon, or the Oregon fab, which is critical for us to accelerate proprietary technology development, new product introduction and improve our financial performance in the long run. To meet the market demand for the more mature high volume products, we also utilize the wafer manufacturing capacity of selected third party foundries. For assembly and test, we primarily rely upon our in-house facilities in China. In addition, we utilize subcontracting partners for industry standard packages. We believe our in-house packaging and testing capability provides us with a competitive advantage in proprietary packaging technology, product quality, cost and sales cycle time.
Factors affecting our performance
Our performance is affected by several key factors, including the following:

The global, regional economic and PC market conditions: Because our products primarily serve consumer electronic applications, a deterioration of the global and regional economic conditions could materially affect our revenue and results of operations. In particular, because a significant amount of our revenue is derived from sales of products in the personal computer, or PC markets, such as notebooks, motherboards and notebook battery packs, a significant decline or downturn in the PC markets can have a material adverse effect on our revenue and results of operations.  Any decline in the PC markets would

39


have a material negative impact on the demand for our products, revenue, factory utilization, gross margin, our ability to resell excess inventory, and other performance measures.

We have been executing and are continuing to execute strategies to diversify our product portfolio and penetrate into other market segments, such as the consumer, communication and industrial market segments, which we believe would mitigate and eventually overcome the reduced demand resulting from the declining PC markets. As we develop and sell new products that serve more diversified markets, we expect that sales based on the PC markets, as a percentage of the total revenue, will continue to decline. Our revenue from the PC markets accounted for approximately 45.2%, 50.0% and 54.4% of our total revenue for the years ended June 30, 2014, 2013 and 2012, respectively. However, if the rate of decline in the PC markets is faster than we expected, or if we cannot successfully diversify or introduce new products to keep pace with the declining PC markets, we may not be able to alleviate its negative impact, which will adversely affect our results of operations.
Erosion of average selling price: Erosion of average selling prices of established products is typical in our industry. Consistent with this historical trend, we expect that average selling prices of our existing products will continue to decline in the future. However, as a normal course of business, we seek to offset the effect of declining average selling prices by introducing new and higher value products, expanding existing products for new applications and new customers, and reducing manufacturing cost of existing products.
Product introductions and customers' product requirements: Our success depends on our ability to introduce products on a timely basis that meet or are compatible with our customers' specifications and performance requirements. Both factors, timeliness of product introductions and conformance to customers' requirements, are equally important in securing design wins with our customers. As we accelerate the development of new technology platforms, we expect to increase the pace at which we introduce new products and obtain design wins. Our failure to introduce products on a timely basis that meet customers' specifications and performance requirements, particularly those products with major OEM customers, and our inability to continue to expand our serviceable markets, could adversely affect our financial performance, including loss of market shares with customers.
Distributor ordering patterns and seasonality: Our distributors place purchase orders with us based on their forecasts of end customer demand, and this demand may vary significantly depending on the sales outlooks and market and economic conditions of end customers. Because these forecasts may not be accurate, channel inventory held at our distributors may fluctuate significantly, which in turn may prompt distributors to make significant adjustments to their purchase orders placed with us. As a result, our revenue and operating results may fluctuate significantly from quarter to quarter. In addition, because our products are used in consumer electronics products, our revenue is subject to seasonality. Our sales seasonality is affected by numerous factors, including global and regional economic conditions as well as the PC market conditions, revenue generated from new products, changes in distributor ordering patterns in response to channel inventory adjustments and end customer demand for our products and fluctuations in consumer purchase patterns prior to major holiday seasons. In recent periods, broad fluctuations in the semiconductor markets and the global and regional economic conditions, in particular the decline of the PC market conditions, have had a more significant impact on our results of operations than seasonality.

Manufacturing Costs:  Our gross margin may be affected by our manufacturing costs, including utilization of our own manufacturing facilities, pricing of wafers from other foundries and semiconductor raw materials, which may fluctuate from time to time largely due to the market demand and supply.  Capacity utilization affects our gross margin because we have certain fixed costs associated with our in-house packaging and testing facilities and our Oregon fab.  If we are unable to utilize the capacity of our in-house manufacturing facilities at a desired level, our gross margin may be adversely affected. For example, we may experience lower capacity utilization at our factories as a result of declining PC markets, which could adversely affect our gross margin and profitability. 
Principal line items of statements of income
The following describes the principal line items set forth in our consolidated statements of operations:
Revenue
We generate revenue primarily from the sale of power semiconductors, consisting of power discretes and power ICs. Historically, a majority of our revenue was derived from power discrete products and a smaller amount was derived from power IC products. Because our products typically have three-year to five-year life cycles, the rate of new product introduction is an important driver of revenue growth over time. We believe that expanding the breadth of our product portfolio is important to our business prospects, because it provides us with an opportunity to increase our total bill-of-materials within an electronic system and to address the power requirements of additional electronic systems. In addition, a small percentage of our total revenue is generated by providing packaging and testing services to third-parties through one of our subsidiaries.

40



Our product revenue includes the effect of the estimated stock rotation returns and price adjustments that we expect to provide to our distributors. Stock rotation returns are governed by contract and are limited to a specified percentage of the monetary value of products purchased by the distributor during a specified period. At our discretion or upon our direct negotiations with the original design manufacturers ("ODMs") or original equipment manufacturers ("OEMs"), we may elect to grant special pricing that is below the prices at which we sold our products to the distributors. In these situations, we will grant price adjustments to the distributors reflecting such special pricing. We estimate the price adjustments for inventory at the distributors based on factors such as distributor inventory levels, pre-approved future distributor selling prices, distributor margins and demand for our products.
Cost of goods sold
Our cost of goods sold primarily consists of costs associated with semiconductor wafers, packaging and testing, personnel, including share-based compensation expense, overhead attributable to manufacturing, operations and procurement, and cost associated with yield improvements, capacity utilization, warranty and inventory reserves. As the volume of sales increases, we expect cost of goods sold to increase. We implemented a process to improve our factory capacity utilization rates by transferring more wafer production to our Oregon fab and reducing our reliance on outside foundries. While our utilization rates cannot be immune to the market conditions, our goal is to make them less vulnerable to market fluctuations. We believe our market diversification strategy and product growth will drive higher volume of manufacturing which will improve our factory utilization rates and gross margin in the long run.
Operating expenses
Our operating expenses consist of research and development, selling, general and administrative expenses and impairment of long-lived assets. We expect that our total operating expenses will generally increase over time due to our belief that our business will continue to grow. However, our operating expenses as a percentage of revenue may fluctuate from period to period.
Research and development expenses.  Our research and development expenses consist primarily of salaries, bonuses, benefits, share-based compensation expense, expenses associated with new product prototypes, travel expenses, fees for engineering services provided by outside contractors and consultants, amortization of software and design tools, depreciation of equipment and overhead costs for research and development personnel. As we continue to invest significant resources in developing new technologies and products, we expect our research and development expenses to increase.
Selling, general and administrative expenses.  Our selling, general and administrative expenses consist primarily of salaries, bonuses, benefits, share-based compensation expense, product promotion costs, occupancy costs, travel expenses, expenses related to sales and marketing activities, amortization of software, depreciation of equipment, maintenance costs and other expenses for general and administrative functions as well as costs for outside professional services, including legal, audit and accounting services. We expect our selling, general and administrative expenses to increase as we expand our business.

Impairment of Long-Lived Assets: Long-lived assets or asset groups are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset might not be recoverable. The recoverability of an asset or asset group is assessed by determining if the carrying value of the asset or asset group exceeds the sum of the projected undiscounted cash flows expected to result from the use and eventual disposition of the assets over the remaining economic life.  The impairment loss is measured based on the difference between the carrying amount and estimated fair value.
Income tax expense
We are subject to income taxes in various jurisdictions. Significant judgment and estimates are required in determining our worldwide income tax expense. The calculation of tax liabilities involves dealing with uncertainties in the application of complex tax regulations of different jurisdictions globally. We establish accruals for potential liabilities and contingencies based on a more likely than not threshold to the recognition and de-recognition of uncertain tax positions. If the recognition threshold is met, the applicable accounting guidance permits us to recognize a tax benefit measured at the largest amount of tax benefit that is more than likely to be realized upon settlement. If the actual tax outcome of such exposures is different from the amounts that were initially recorded, the differences will impact the income tax and deferred tax provisions in the period in which such determination is made. Changes in the location of taxable income (loss) could result in significant changes in our income tax expense.


41


We record a valuation allowance against deferred tax assets if it is more likely than not that a portion of the deferred tax assets will not be realized, based on historical profitability and our estimate of future taxable income in a particular jurisdiction. Our judgments regarding future taxable income may change due to changes in market conditions, changes in tax laws, tax planning strategies or other factors. If our assumptions and consequently our estimates change in the future, the deferred tax assets may increase or decrease, resulting in corresponding changes in income tax expense. Our effective tax rate is highly dependent upon the geographic distribution of our worldwide profits or losses, the tax laws and regulations in each geographical region where we have operations, the availability of tax credits and carry-forwards and the effectiveness of our tax planning strategies.

Fiscal 2014 vs 2013

Total revenue was $318.1 million for fiscal year 2014, a decrease of $19.3 million, or 5.7%, as compared to $337.4 million for fiscal year 2013. The decrease consisted of $19.1 million and $1.4 million decrease in sales of power discrete products and packaging and testing services, respectively, partially offset by an increase in sales of power IC products of $1.2 million. The net decrease in product revenue, including power discrete and power IC products was mainly a result of a 7.0% decrease in average selling price primarily due to selling price erosion in the computing and consumer markets as compared to fiscal year 2013, partially offset by a 1.2% increase in unit shipments and to a lesser extent, a shift in product mix as a result of reduced demand for our products related to PC applications. The decrease in revenue of packaging and testing services as compared to last year was primarily due to reduced demand as a result of the declining PC market. In response to the declining PC market, we have been executing and are continuing to execute strategies to diversify our product portfolio and penetrate into other market segments, which we believe would mitigate and eventually overcome the reduced demand resulting from the declining PC market. During fiscal year 2014, we accelerated the development of new technology platforms which allowed us to introduce 62 medium and high voltage MOSFET products, targeting the consumer, communication and industrial markets, as well as 48 low voltage MOSFET products for the computing market. In addition, we introduced 23 Power IC new products for consumer, communications and computing applications.

Fiscal 2013 vs 2012

Total revenue was $337.4 million for fiscal year 2013, a decrease of $4.9 million, or 1.4%, as compared to $342.3 million for fiscal year 2012. The decrease consisted of $1.9 million, $0.6 million and $2.4 million decrease in sales of power discrete, power IC products and packaging and testing services, respectively. The decrease in sales of power discrete and power IC products was mainly a result of a 4.2% decrease in average selling price partially offset by a 3.8% increase in unit shipments as compared to last year. The 4.2% decrease in average selling price was mainly due to a shift in product mix, the reduced demand for our products related to PC applications, and to a lesser extent, selling price erosion in the computing and consumer markets. The decrease in revenue of packaging and testing services as compared to last year was primarily due to reduced demand as a result of the declining PC market.

Fiscal 2014 vs 2013

Cost of goods sold was $259.1 million for fiscal year 2014, a decrease of $13.8 million, or 5.1%, as compared to $272.9 million for fiscal year 2013, primarily as a result of the overall manufacturing cost reduction due to continued cost control efforts and factory utilization improvement during fiscal year 2014 as well as the impact of the $7.7 million non-recurring inventory write-down during fiscal year 2013 for certain excess and obsolete inventory consisting of developed products for PC applications for a major OEM that were not compatible with its particular applications, which had subsequently been fully resolved. Gross margin decreased by 0.5 percentage points to 18.6% for fiscal year 2014, as compared to 19.1% for fiscal year

43


2013. The decrease in gross margin was primarily due to reduced average selling price mainly as a result of lower demand in the declining PC market during the current year, despite the $7.7 million non-recurring inventory write-down in fiscal year 2013, partially offset by the positive impact of improved factory utilization and continued factory cost reduction efforts during the current year. We expect our gross margin to continue to fluctuate in the future as a result of variations in our product mix, factory utilization, semiconductor wafer and raw material pricing, manufacturing labor cost and general economic and PC market conditions.

Fiscal 2013 vs 2012

Cost of goods sold was $272.9 million for fiscal year 2013, an increase of $13.7 million, or 5.3%, as compared to $259.1 million for fiscal year 2012, primarily as a result of a $7.7 million non-recurring inventory write-down and increased unit shipments. The non-recurring inventory write-down was for certain excess and obsolete inventory consisting of newly developed products for desktop PC applications primarily for a major OEM that were not compatible with its particular applications, and to a lesser extent, products for power supplies. Gross margin decreased by 5.2 percentage points to 19.1% for fiscal year 2013, as compared to 24.3% for fiscal year 2012. The decrease in gross margin was primarily due to the non-recurring inventory write-down of $7.7 million, as well as reduced average selling price, partially offset by tighter factory expense control as compared to last year.

Fiscal 2014 vs 2013

Research and development expenses were $24.4 million for fiscal year 2014, a decrease of $3.4 million, or 12.3%, as compared to $27.8 million for fiscal year 2013. The decrease was primarily attributable to a $2.6 million decrease in product prototyping engineering expenses mainly due to temporary shut downs of the Company as cost control measures, $0.6 million decrease in shared-based compensation expense primarily due to increased cancellations of stock options and rewards, $0.2 million decrease in depreciation and amortization expenses as a result of certain assets were fully amortized in fiscal year of 2013. We continue to invest significant resources in developing new technologies and new products utilizing our own fabrication and packaging facilities. However, we expect that our research and development expenses will fluctuate from time to time.

Fiscal 2013 vs 2012

Research and development expenses were $27.8 million for fiscal year 2013, a decrease of $2.8 million, or 9.1%, as compared to $30.6 million for fiscal year 2012. The decrease was primarily attributable to a $3.6 million decrease in product prototyping engineering expenses, mainly related to engineering wafers expenses incurred during fiscal year 2012 under the then foundry agreement with IDT prior to the acquisition of the Oregon fab. The decrease was partially offset by a $0.7 million increase in employee compensation and benefits primarily due to increase in headcount related to the Oregon fab acquired in January 2012.

Selling, general and administrative expenses were $34.9 million for fiscal year 2014, a decrease of $0.6 million, or 1.7%, as compared to $35.5 million for fiscal year 2013. The decrease was primarily due to a $0.7 million decrease in share-based compensation due to increased cancellations of stock options and awards during the current year, a $0.7 million decrease in depreciation and amortization expenses primarily due to certain assets that were fully amortized in fiscal year 2013 and less acquisitions of fixed assets during the current year, a $0.3 million decrease in marketing and commission expenses due to reduced sales and marketing activities, a $0.4 million in recovery of doubtful accounts as a result of continued effort in collection from a service customer in current fiscal year, as well as a $0.4 million decrease in audit and tax consulting fees due to reduced related consulting activities. These decreases were partially offset by a $0.8 million increase in unrealized foreign exchange losses related to our cash and cash equivalents denominated in Renminbi or RMB, held by our subsidiaries in China, caused by the recent appreciation of USD against RMB, and a $0.8 million increase in employee compensation and benefits due to headcount increase, as well as a $0.3 million of business tax refunds of a subsidiary in China during fiscal year 2013.

Fiscal 2013 vs 2012

Selling, general and administrative expenses were $35.5 million for fiscal year 2013, a decrease of $0.3 million, or 0.9%, as compared to $35.8 million for fiscal year 2012. The decrease was primarily due to a $0.8 million decrease in share-based compensation due to increased cancellations of stock options and other equity awards, a $0.7 million decrease in accounting, Sarbanes-Oxley compliance and consulting fees due to the decrease in related accounting and consulting activities, a $0.3 million decrease in business taxes primarily due to a business tax refund received by a subsidiary in China during fiscal year 2013, a $0.2 million decrease in sales commission primarily due to decrease in sales and a $0.6 million bad debt expenses incurred related to a service customer during fiscal year 2012, and these decreases were partially offset by a $1.4 million increase in employee compensation, benefits and business expenses mainly due to increase in headcount, a $0.3 million increase in depreciation and amortization expenses primarily due to fixed assets acquired during fiscal year 2013 and a $0.6 million increase in legal expenses due to increased legal consulting services.
Impairment of long-lived assets

During the third quarter of fiscal year 2013, in light of the unfavorable market conditions particularly related to the accelerated decline of the PC market, we conducted an in-depth analysis of our strategic plan. In our review, we reconsidered the key assumptions in our overall strategic business and manufacturing capacity plans in light of the continued declines in the PC market. As a result, we revised our PC related revenue and volume outlook as well as our manufacturing capacity requirements. These material changes in our outlook and plans, which we were able to determine in the third quarter of fiscal 2013, triggered an impairment review of our long-lived assets.

We determined that the related estimated undiscounted cash flows were not sufficient to recover the carrying value of certain manufacturing machinery and equipment primarily for the packaging of our PC-related products due to the accelerated decline of the PC markets. The average remaining useful life of those impaired assets was approximately two years. We estimated the fair values of those long-lived assets based on net realizable values of similar machinery and equipment recently transacted by third-party used-machine brokers and recorded an asset impairment charge of approximately $2.6 million to reduce the related carrying amount to its estimated fair value as of March 31, 2013.

During the fourth quarter of fiscal year 2014, we evaluated our amortizable intangible assets for impairment and determined that the related estimated undiscounted cash flows exceeded the carrying value of the intangible assets and no impairment charge was recorded. During the same period, we also evaluated our goodwill for impairment and determined that the fair value of the reporting unit, estimated based on the market capitalization approach, was more than its carrying value and no impairment charge was recorded.
Interest income and expenses

Interest income was primarily related to interest earned from cash and cash equivalents. The increase in interest income for fiscal year 2014 as compared to fiscal year 2013 was primarily due to increase in average cash balances. The decrease in interest income for fiscal year 2013 as compared to fiscal year 2012 was primarily due to lower average interest rate.

Interest expense was primarily related to bank borrowings. The decrease in interest expenses for fiscal year 2014 was primarily due to a decrease in bank borrowings related to $20.0 million term loan obtained in May 2012 for our Oregon fab as compared to fiscal year 2013. The increase in interest expenses for fiscal year 2013 was primarily due to an increase in bank borrowings, including the $20.0 million term loan obtained in May 2012 for working capital of our Oregon fab as compared to fiscal year 2012.

Fiscal 2014 vs 2013

Income tax expense for fiscal years 2014 and 2013 was $3.0 million and $4.0 million, respectively. Income tax expense decreased by $1.0 million, or 25.7%, in fiscal year 2014 as compared to fiscal year 2013 primarily due to a reduction in our uncertain tax positions offset partially by a change in the mix of earnings in various geographic jurisdictions.

Fiscal 2013 vs 2012

Income tax expense for fiscal years 2013 and 2012 was $4.0 million and $3.6 million, respectively. Income tax expense increased by $0.4 million, or 11.7%, in fiscal year 2013 as compared to fiscal year 2012 primarily due to the changes in the mix of earnings in various geographic jurisdictions, which was partially offset by the tax benefits from the January 2013 reinstatement of the U.S. federal R&D credit retroactive to January 1, 2012.

Liquidity and Capital Resources

Our principal need for liquidity and capital resources is to maintain sufficient working capital to support our operations and to invest adequate capital expenditures to fuel the growth of our business. Currently, we primarily financed our operations and capital expenditures through funds generated from operations.

On May 11, 2012, we entered into a loan agreement with a financial institution that provides a term loan of $20.0 million for general purposes and a $10.0 million non-revolving credit line for the purchase of equipment. Both the term loan and equipment credit line will be fully repayable in May 2015. The borrowings may be made in the form of either Eurodollar loans or Base Rate loans. Eurodollar loans accrue interest based on an adjusted London Interbank Offer Rate ("LIBOR") as defined in the agreement, plus a margin of 1.00% to 1.75%. Base Rate loans accrue interest at the highest of (a) the lender's Prime Rate, (b) the Federal Funds Rate plus 0.5% and (c) the Eurodollar Rate (for a one-month interest period) plus 1%; plus a margin of -0.5% to 0.25%. The applicable margins for both Eurodollar loans and Base Rate loans will vary from time to time in the foregoing ranges based on the cash and cash equivalent balances maintained by us and our subsidiaries with the lender. In May 2013, the equipment credit line expired and there was no outstanding balance. As of July 31, 2014 and 2013, the outstanding balance of the term loan was $13.5 million and $16.4 million, respectively.

The obligations under the loan agreement are secured by substantially all assets of two of our subsidiaries, including but not limited to, certain real property and related assets located at the Oregon fab. In addition, we and certain of our subsidiaries have agreed to guarantee full repayment and performance of the obligations under the loan agreement. The loan agreement contains customary restrictive covenants and includes certain financial covenants that require us to maintain on a consolidated basis specified financial ratios including total liabilities to tangible net worth, fixed charge coverage and current assets to current liabilities. As of July 31, 2014 and 2013, we were in compliance with these covenants.

During July 2012, we entered into a loan agreement with the State of Oregon for an amount of $0.3 million. The loan is required to be used for training new and re-training existing employees of the Oregon fab. The loan bears a compound annual interest rate of 5.0% and is to be repaid in April 2014. The State may forgive the outstanding balance under the loan and any unpaid interest if we meet certain conditions primarily relating to hiring targets. Currently the State of Oregon is reviewing the loan to determine whether such conditions are satisfied. We believe that it is more likely than not that we will meet those hiring targets. As of July 31, 2014, the outstanding balance and accrued interest of the loan, included in short term debt, was $0.3 million.

Our Board of Directors periodically considers various options to utilize our cash reserve to enhance the value of our shareholders. On May 8, 2014, our Board of Directors approved to reactivate our existing $25.0 million share repurchase program and authorized management to repurchase, subject to oversight by the Board, our common shares up to remaining balance of the program, or $22.7 million. The repurchases may be made from the open market or through negotiated block transactions, and to date repurchases have been made pursuant to a pre-established 10b5-1 trading plan. Such 10b5-1 trading plan was expired in Augus

46


t 2014 and the Board intends to review conditions from time to time to determine whether it is appropriate to implement a new 10b5-1 trading plan or to conduct repurchases under the program outside of a 10b5-1 trading plan. The amount and timing of any purchases will depend on a number of factors, including but not limited to the price and availability of our common shares, trading volume of our common shares, applicable regulatory requirements, our business and financial conditions and general market environment, and there is no guarantee that any repurchases will be made or that such repurchases may enhance the value of our shares. During the fourth quarter of fiscal year 2014, we repurchased 119,594 shares from the open market for a total cost of $0.9 million, at an average price of $7.66 per share. As of June 30, 2014, we repurchased an aggregate of 361,364 shares from the open market for a total cost of $3.2 million, at an average price of $8.82 per share, since inception of the program. Shares repurchased are accounted for as treasury shares and the total cost of shares repurchased is recorded as a reduction of shareholders' equity. As of June 30, 2014, of the 361,364 repurchased shares, 21,650 shares with a weighted average repurchase price of $13.81 per share, were reissued at an average price of $3.00 per share for option exercises and vested restricted stock units.    

The Chinese government imposes certain currency exchange controls on cash transfers out of China. Regulations in China permit foreign owned entities to freely convert the Renminbi into foreign currency for transactions that fall under the "current account," which includes trade related receipts and payments, and interests. Accordingly, our Chinese subsidiaries may use Renminbi to purchase foreign exchange currency for settlement of such "current account" transactions without pre-approval.

Other transactions that involve conversion of Renminbi into foreign currency are classified as "capital account" transactions. Examples of "capital account" transactions include repatriations of investments by or dividends to foreign owners. Pursuant to applicable regulations, foreign-invested enterprises in China may pay dividends only out of their accumulated profits, if any, determined in accordance with Chinese accounting standards and regulations. In calculating accumulated profits, foreign investment enterprises in China are required to allocate at least 10% of their profits each year, if any, to fund the equity reserve account unless the reserve has reached 50% of the registered capital of the enterprises. "Capital account" transactions require prior approval from China's State Administration of Foreign Exchange (SAFE) or its provincial branch to convert a remittance into a foreign currency, such as U.S. dollars, and transmit the foreign currency outside of China. As a result of this and other restrictions under PRC laws and regulations, our China subsidiaries are restricted in their ability to transfer a portion of their net assets to the parent.  As of June 30, 2014 and 2013, such restricted portion amounted to approximately $85.6 million and $85.9 million, or 30.3% and 30.5%, of our total consolidated net assets, respectively.
    
We believe that our current cash and cash equivalents and cash flows from operations will be sufficient to meet our anticipated cash needs, including working capital and capital expenditures, for at least the next twelve months. In the long-term, we may require additional capital due to changing business conditions or other future developments, including any investments or acquisitions we may decide to pursue. If our cash is insufficient to meet our needs, we may seek to raise capital through equity or debt financing. The sale of additional equity securities could result in dilution to our shareholders. The incurrence of indebtedness would result in increased debt service obligations and may include operating and financial covenants that would restrict our operations. We cannot be certain that any financing will be available in the amounts we need or on terms acceptable to us, if at all.
Cash and cash equivalents
As of June 30, 2014 and 2013, we had $117.8 million and $92.4 million of cash and cash equivalents, respectively. Our cash and cash equivalents primarily consist of cash on hand and short-term bank deposits with original maturities of three months or less. Of the $117.8 million and $92.4 million cash and cash equivalents, $77.0 million and $53.2 million, respectively, are deposited with financial institutions outside the United States.

Cash flows from operating activities


47


Net cash provided by operating activities of $37.6 million for fiscal year 2014 resulted primarily from net loss of $3.3 million, non-cash charges of $31.5 million and net change in assets and liabilities providing net cash of $9.4 million. The non-cash charges of $31.5 million included depreciation and amortization expenses of $27.9 million, share-based compensation expense of $3.4 million, and net deferred income taxes of $0.8 million, partially offset by allowance for doubtful account of $0.4 million and gain on disposal of property and equipment of $0.2 million during the fiscal year 2014. The net change in assets and liabilities providing net cash of $9.4 million was primarily due to $1.8 million decrease in inventories as we reduced our inventories, $2.1 million decrease in accounts receivable due to the timing of billings and collection of payments, $5.5 million increase in accounts payable primarily due to increase in inventory purchase and timing of payment, and $2.4 million increase in accrued and other liabilities primarily related to employee compensation and performance bonuses, partially offset by $0.9 million decrease in income taxes payable, and $1.5 million increase in other current and long-term assets primarily due to increase in advance payments to suppliers.

Net cash provided by operating activities of $28.0 million for fiscal year 2013 resulted primarily from net loss of $5.6 million, non-cash charges of $37.8 million and net change in assets and liabilities using net cash of $4.2 million. The non-cash charges of $37.8 million included $29.4 million in depreciation and amortization expenses, $4.8 million in share-based compensation expense, $1.0 million in net deferred income taxes, and $2.6 million in impairment charges of long-lived assets during the third quarter. The net change in assets and liabilities using net cash of $4.2 million was primarily due to $0.7 million decrease in income taxes payable, $2.6 million increase in inventories as we built up our inventories for the Oregon fab ramp up, and $5.4 million decrease in accrued and other liabilities primarily related to payment of performance bonuses, partially offset by $0.6 million decrease in accounts receivable due to the timing of billings and collection of payments, $1.8 million increase in accounts payable primarily due to increase in inventory purchase and timing of payment, and $2.1 million decrease in other current and long-term assets primarily due to decrease in advance payments to suppliers.

Net cash provided by operating activities of $32.9 million for fiscal year 2012 resulted primarily from net income of $12.9 million, non-cash charges of $29.8 million and net change in assets and liabilities using net cash of $9.8 million. The non-cash charges of $29.8 million included $25.3 million in depreciation and amortization, $5.4 million in share-based compensation expense and $0.6 million in allowance for doubtful accounts, partially offset by $1.5 million in net deferred income taxes. The net change in working capital using net cash of $9.8 million was primarily due to $3.1 million decrease in accounts receivable due to the timing of billings and collection of payments, $1.6 million decrease in inventories as we reduced our inventories in response to changes in market condition, $1.3 million decrease in other current and long-term assets primarily due to a decrease in advance payments to suppliers, $4.5 million increase in accrued and other liabilities primarily related to expenses of the Oregon fab and $0.4 million increase in income taxes payable, offset by a $20.8 million decrease in accounts payable primarily due to timing of payment.
Cash flows from investing activities

Net cash used in investing activities of $9.2 million for the fiscal year 2014 was primarily attributable to $9.4 million purchase of property and equipment to increase our in-house production capacity, partially offset by $0.2 million proceeds from sale of certain equipment.

Net cash used in investing activities of $17.3 million for the fiscal year 2013 was primarily attributable to $17.6 million purchase of property and equipment to increase our in-house production capacity, partially offset by $0.3 million proceeds from sale of certain equipment.

Net cash used in investing activities of $57.9 million for fiscal year 2012 was primarily attributable to $36.3 million for purchase of property and equipment to increase our in-house production capacity at the Oregon fab facility, $21.3 million of cash for acquisition of the Oregon fab in January 2012, $0.2 million increase in restricted cash, and $0.1 million related to the investment in a privately held company.
Cash flows from financing activities

Net cash used in financing activities of $3.1 million for the fiscal year 2014 was primarily attributable to $3.6 million of repayment to our borrowings, $1.0 million for repurchase of our common shares under the repurchase program, and $1.3 million in payment of capital lease obligations; partially offset by a $2.7 million of proceeds from exercises of share options and issuance of shares under the ESPP.


48


Net cash used in financing activities of $0.5 million for the fiscal year 2013 was primarily attributable to $2.6 million of net repayment to our borrowings and $1.0 million in payment of capital lease obligations; partially offset by a $3.1 million of proceeds from exercises of share options and issuance of shares under the ESPP.
Net cash provided by financing activities of $20.5 million for fiscal year 2012 was primarily attributable to $20.0 million of net proceeds from our revolving lines of credit and term loan and $2.3 million of proceeds from exercise of share options and ESPP, partially offset by $1.6 million for repurchase of our common shares under the share repurchase program and $0.3 million in payment of capital lease obligations.

As of June 30, 2014, we had recorded liabilities of $2.0 million for uncertain tax positions and $0.3 million for potential interest and penalties, which are not included in the above table because we are unable to reliably estimate the amount of payments in individual years that would be made in connection with these uncertain tax positions.
Off-Balance Sheet Arrangements

As of June 30, 2014, we had no material off-balance sheet arrangements as defined in Item 303(a)(4)(ii) of Regulation S-K.

Critical Accounting Policies and Estimates
The preparation of our consolidated financial statements requires us to make estimates, judgments and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses. To the extent there are material differences between these estimates and actual results, our consolidated financial statements will be affected. On an ongoing basis, we evaluate the estimates, judgments and assumptions including those related to revenue recognition, inventory reserves, warranty accrual, income taxes, share-based compensation, and useful lives for property and equipment and for goodwill and intangible assets.
Revenue recognition
We recognize revenue when there is persuasive evidence that an arrangement exists, delivery has occurred, the price to the buyer is fixed or determinable and when collectability is reasonably assured. We recognize revenue when product is shipped to the customer, net of estimated stock rotation returns and price adjustments to certain distributors.
We sell our products primarily to distributors, who in turn sell our products globally to various end customers. Our revenue is net of the effect of the estimated stock rotation returns and price adjustments that we expect to provide to certain distributors. Stock rotation returns are governed by contract and are limited to a specified percentage of the monetary value of the products purchased by distributors during a specified period. We estimate provision for stock rotation returns based on historical returns and individual distributor agreements. We also provide special pricing to certain distributors primarily based on volume, to encourage resale of our products. We estimate the expected price adjustments at the time the revenue is

49


recognized based on distributor inventory levels, pre-approved future distributor selling prices, distributor margins and demand for our products. If actual stock rotation returns or price adjustments differ from our estimates, adjustments may be recorded in the period when such actual information is known. Allowance for price adjustments is recorded against accounts receivable and provision for stock rotation is recorded in accrued liabilities on the consolidated balance sheets.
Revenue from certain distributors is deferred until the distributor resells the products to end customers due to price protection adjustments and right of returns that cannot be reliably measured. The deferred revenue, net of the associated deferred cost of the inventory, is recorded as deferred margin on the consolidated balance sheets.
Packaging and testing services revenue is recognized upon shipment of serviced products to the customer.
Inventory reserves
We carry inventories at the lower of cost (determined on a first-in, first-out basis) or market value. Cost primarily consists of semiconductor wafers and raw materials, labor, depreciation expenses and other manufacturing expenses and overhead, and packaging and testing fees paid to third parties if subcontractors are used. Inventory reserves are made based on our periodic review of inventory quantities on hand as compared with our sales forecasts, historical usage, aging of inventories, production yield levels and current product selling prices. If actual market conditions are less favorable than those forecasted by us, additional future inventory write-downs may be required that could adversely affect our operating results. Inventory reserves once established are not reversed until the related inventory has been sold or scrapped. If actual market conditions are more favorable than expected and the products that have previously been written down are sold, our gross margin would be favorably impacted.
Product warranty
We provide a standard one-year warranty for the products we sell. We accrue for estimated warranty costs at the time revenue is recognized. Our warranty obligation is affected by product failure rates, labor and material costs for replacing defective parts, related freight costs for failed parts and other quality assurance costs. We monitor our product returns for warranty claims and maintain warranty reserve based on our historical experiences and anticipated warranty claims known at the time of estimation. If actual warranty costs differ significantly from our estimates, revisions to the estimated warranty accrual would be required and any such adjustments could be material.
Accounting for income taxes
We are subject to income taxes in a number of jurisdictions. We must make certain estimates and judgments in determining income tax expense for financial statement purposes. These estimates and judgments occur in the calculation of tax credits, benefits and deductions, and in the calculation of certain tax assets and liabilities which arise from differences in the timing of recognition of revenue and expense for tax and financial statement purposes, as well as interest and penalties related to uncertain tax positions. There are many transactions and calculations for which the ultimate tax determination is uncertain during the ordinary course of business. We establish accruals for certain tax contingencies based on estimates of whether additional taxes may be due. While the final tax outcome of these matters may differ from the amounts that were initially recorded, such differences will impact the income tax and deferred tax provisions in the period in which such determination is made.  As a result, significant changes to these estimates may result in an increase or decrease to our tax provision in a subsequent period.
    
Significant management judgment is also required in determining whether deferred tax assets will be realized in full or in part. When it is more likely than not that all or some portion of specific deferred tax assets such as net operating losses or foreign tax credit carryforwards will not be realized, a valuation allowance must be established for the amount of the deferred tax assets that cannot be realized. We consider all available positive and negative evidence on a jurisdiction-by-jurisdiction basis when assessing whether it is more likely than not that deferred tax assets are recoverable. We consider evidence such as our past operating results, the existence of cumulative losses in recent years and our forecast of future taxable income. We intend to maintain a partial valuation allowance equal to the state research and development credit carryfowards until sufficient positive evidence exists to support reversal of the valuation allowance.
    
We have not provided for withholding taxes on the undistributed earnings of our foreign subsidiaries because we intend to reinvest such earnings indefinitely. As of June 30, 2014, the cumulative amount of undistributed earnings of our foreign subsidiaries considered permanently reinvested is $49.8 million. The determination of the unrecognized deferred tax liability on these earnings is not practicable. Should we decide to remit this income to the Bermuda parent company in a future period, our provision for income taxes may increase materially in that period.

50


    
The Financial Accounting Standards Board, or FASB, has issued guidance which clarifies the accounting for income taxes by prescribing a minimum probability threshold that a tax position must meet before a financial statement benefit is recognized. The minimum threshold is defined as a tax position that is more likely than not to be sustained upon examination by the applicable taxing authority, including resolution of any related appeals or litigation processes, based on the technical merits of the position. The tax benefit to be recognized is measured as the largest amount of benefit that is greater than fifty percent likely to be realized upon ultimate settlement. The calculation of our tax liabilities involves dealing with uncertainties in the application of complex tax law and regulations in a multitude of jurisdictions. Although the guidance on the accounting for uncertainty in income taxes prescribes the use of a recognition and measurement model, the determination of whether an uncertain tax position has met those thresholds will continue to require significant judgment by management. If the ultimate resolution of tax uncertainties is different from what is currently estimated, a material impact on income tax expense could result.

Our provision for income taxes is subject to volatility and could be adversely impacted by changes in earnings or tax laws and regulations in various jurisdictions. We are subject to the continuous examination of our income tax returns by the Internal Revenue Service and other tax authorities. We regularly assess the likelihood of adverse outcomes resulting from these examinations to determine the adequacy of our provision for income taxes. There can be no assurance that the outcomes from these continuous examinations will not have an adverse effect on our operating results and financial condition. To the extent that the final tax outcome of these matters is different than the amounts recorded, such differences will impact the provision for income taxes in the period in which such determination is made. The provision for income taxes includes the impact of changes to reserves, as well as the related net interest and penalties.
Share-based compensation expense
We recognize share-based compensation expense based on the estimated fair value of the awards determined by the Black-Scholes option valuation model, using the accelerated vesting attribution method. Share-based compensation expense is significant to the consolidated financial statements and is calculated using our best estimates, which involve inherent uncertainties and the application of management's judgment.
We determined the weighted average valuation assumptions as follows:
Expected term. It is determined by using the historical data of industry peers as adjusted for expected changes in future exercise patterns.
Forfeiture rate. It is estimated based on the historical average period of time that the awards were outstanding and forfeited. The estimate of forfeitures is adjusted over the requisite service period to the extent that actual forfeitures differ, or are expected to differ, from the prior estimates. Changes in estimated forfeitures are recognized in the period of change and impact the amount of stock compensation expenses to be recognized in future periods, which could be material if actual results differ significantly from our estimates.
Volatility. It is estimated based on that of the publicly traded shares of industry peers over a period equivalent to the expected term of the stock awards granted.
Risk-free interest rate. It is based on the yields of U.S. Treasury securities with maturities similar to the expected term of the awards granted.
Dividend yield. It is zero as the Company has never declared or paid any dividends and currently has no intention to pay dividends in the foreseeable future.
Estimated Useful Lives for Property, Plant and Equipment and Intangible Assets
Property, plant and equipment are recorded at cost and are depreciated using the straight-line method over estimated useful lives of the assets. Patents and exclusive technology rights purchased from third parties are amortized on a straight-line basis over their estimated useful lives of three to seven years. Trade name and customer relationships acquired in a business combination are recognized at fair values at the acquisition date and amortized on a straight-line basis over their estimated economic lives of three years and four years, respectively.
Goodwill

51


Goodwill and intangible assets with indefinite useful lives are not amortized, but are tested for impairment at least annually, or whenever changes in circumstances indicate that the carrying amount of goodwill or intangible assets may not be recoverable. These tests are performed at the reporting unit level using a two-step, fair-value based approach. In testing for a potential impairment of goodwill, we first compare the carrying value of assets and liabilities to the estimated fair value. If estimated fair value is less than carrying value, then potential impairment exists. The amount of any impairment is then calculated by determining the implied fair value of goodwill using a hypothetical purchase price allocation, similar to that which would be applied if it were an acquisition and the purchase price was equivalent to fair value as calculated in the first step. Impairment is equivalent to any excess of goodwill carrying value over its implied fair value. The process of evaluating the potential impairment of goodwill requires significant judgment at many points during the analysis, including calculating fair value of each reporting unit based on estimated future cash flows and discount rates to be applied.

Item 7A.
Quantitative and Qualitative Disclosures About Market Risk
Foreign currency risk
    
We and our principal subsidiaries use U.S. dollars as our functional currency because most of the transactions are conducted and settled in U.S. dollars. All of our revenue and a significant portion of our operating expenses are denominated in U.S. dollars. The functional currency for our in-house packaging and testing facilities in China is U.S. dollars and a significant portion of our capital expenditures are denominated in U.S. dollars. However, foreign currencies are required to fund our overseas operations, primarily in Taiwan and China. Operating expenses of overseas operations are denominated in their respective local currencies. In order to minimize exposure to foreign currencies, we maintained cash and cash equivalent balances in foreign currencies, including Chinese Yuan (“RMB”) as operating funds for our foreign operating expenses. Our management believes that our exposure to foreign currency translation risk is not significant based on a 10% sensitivity analysis in foreign currencies due to the fact that the net assets denominated in foreign currencies pertaining to foreign operations, principally in Taiwan and China, are not significant to our consolidated net assets.
Interest rate risk
Our interest-bearing assets comprise mainly interest-bearing short-term bank balances. We manage our interest rate risk by placing such balances in instruments with various short-term maturities. Borrowings expose us to interest rate risk. Borrowings are drawn down after due consideration of market conditions and expectation of future interest rate movements. In the past, our borrowings have been subject to floating interest rates, and future borrowings may expose us to cash-flow interest rate risk. We had outstanding borrowings of $13.6 million at June 30, 2014. We do not believe that a 10% change in interest rates would materially affect our results of operations.

Commodity Price Risk

We are subject to risk from fluctuating market prices of certain commodity raw materials, particularly gold, that are used in our manufacturing process and incorporated into our end products. Supplies for such commodities may from time-to-time become restricted, or general market factors and conditions may affect the pricing of such commodities. Over the past few years, the price of gold increased significantly and certain of our supply chain partners assess surcharges to compensate for the rising commodity prices. We have been converting some of our products to use copper wires instead of gold wires. Our results of operations may be materially and adversely affected if we have difficulty obtaining these raw materials, the quality of available raw materials deteriorates, or there are significant price changes for these raw materials. For periods in which the prices of these raw materials are rising, we may be unable to pass on the increased cost to our customers which would result in decreased margins for the products in which they are used and could have a material adverse effect on our net earnings. We also may need to record losses for adverse purchase commitments for these materials in periods of declining prices. We do not enter into formal hedging arrangements to mitigate against commodity risk. We estimate that a 10% increase or decrease in the costs of raw materials such as gold, subject to commodity price risk would decrease or increase our current year's net earnings by $1.8 million, assuming that such changes in our costs have no impact on the selling prices of our products and that we have no pending commitments to purchase metals at fixed prices.

Financial Statements and Supplementary Data
See Part IV, Item 15 "Exhibits and Financial Statement Schedules" for our consolidated financial statements and the notes and schedules thereto filed as part of this annual report.
 Selected Quarterly Consolidated Financial Data
The following tables present our unaudited consolidated financial information for each of the eight quarters in the period ended June 30, 2014. Net income per share for the four quarters of each fiscal year may not sum to the total for the fiscal year because of difference in the number of shares outstanding during each period. The operating results for any quarter should not be relied upon as necessarily indicative of results for any future period. We expect our quarterly operating results to fluctuate in future periods due to a variety of reasons, including those discussed in Item 1A. “Risk Factors.”

Item 9.
Changes in and Disagreements with Accountants on Accounting and Financial Disclosure
Not applicable.

Item 9A.
Controls and Procedures
Evaluation of Disclosure Controls and Procedures
Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended, (the “Exchange Act”)), as of the end of the period covered by this report. Based on that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures as of June 30, 2014 have been designed and are functioning effectively to provide reasonable assurance that the information required to be disclosed in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC's rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.
Management's Annual Report on Internal Control over Financial Reporting

54


Our management, including our Chief Executive Officer and Chief Financial Officer, is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rule 13a-15(f) and Rule 15d-15(f). Our internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of our financial statements for external purposes in accordance with generally accepted accounting principles, and includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of our assets; (2) provide reasonable assurance that transactions are recorded to permit preparation of financial statements in accordance with generally accepted accounting principles, and that our receipts and expenditures are made only in accordance with authorizations of our management and directors; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on our financial statements.
Our management, including our Chief Executive Officer and Chief Financial Officer, assessed the effectiveness of our internal control over financial reporting as of June 30, 2014. In performing this assessment, management used the criteria established in internal control (1992) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based upon this assessment, our management has concluded that, as of June 30, 2014, our internal control over financial reporting was effective.
The effectiveness of the Company's internal control over financial reporting as of June 30, 2014 has been audited by Grant Thornton LLP, an independent registered public accounting firm, as stated in their report, included on the following page.
Limitation on the Effectiveness of Controls    
While our disclosure controls and procedures and internal control over financial reporting are designed to provide reasonable assurance that their respective objectives will be met, we do not expect that our disclosure controls and procedures or our internal control over financial reporting are or will be capable of preventing or detecting all errors and all fraud. Any control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system's objectives will be met.
Changes in Internal Control Over Financial Reporting
There were no changes in our internal control over financial reporting that occurred during the quarter ended June 30, 2014 that have materially affected or are reasonably likely to materially affect, our internal control over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Board of Directors and Stockholders
Alpha and Omega Semiconductor Limited
 
We have audited the internal control over financial reporting of Alpha and Omega Semiconductor Limited (a Bermuda corporation) and subsidiaries (the “Company”) as of June 30, 2014, based on criteria established in the 1992 Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Annual Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

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 (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) 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 (3) 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.

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.

In our opinion, Alpha and Omega Semiconductor Limited and subsidiaries maintained, in all material respects, effective internal control over financial reporting as of June 30, 2014, based on criteria established in the 1992 Internal Control-Integrated Framework issued by COSO.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated financial statements of the Company as of and for the year ended June 30, 2014, and our report dated August 29, 2014 expressed an unqualified opinion on those consolidated financial statements and schedules.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Board of Directors and Stockholders
Alpha and Omega Semiconductor Limited
 
We have audited the accompanying consolidated balance sheets of Alpha and Omega Semiconductor Limited (a Bermuda corporation) and subsidiaries (the “Company”) as of June 30, 2014 and 2013, and the related consolidated statements of comprehensive income (loss), changes in shareholders’ equity, and cash flows for each of the three years in the period ended June 30, 2014. Our audits of the basic consolidated financial statements included the financial statement schedules listed in the index appearing under Item 15(a)(2). These financial statements and financial statement schedules are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements and financial statement schedules based on our 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 audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Alpha and Omega Semiconductor Limited and subsidiaries as of June 30, 2014 and 2013, and the results of their operations and their cash flows for each of the three years in the period ended June 30, 2014 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the related financial statement schedules, when considered in relation to the basic consolidated financial statements taken as a whole, presents fairly, in all material respects, the information set forth therein.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the Company’s internal control over financial reporting as of June 30, 2014, based on criteria established in the 1992 Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO), and our report dated August 29, 2014 expressed an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting.
