(the “Company”) is a leading innovator of lighting-class light emitting diode (LED) products, lighting products and semiconductor products for power and radio-frequency (RF) applications. The Company's products are targeted for applications such as indoor and outdoor lighting, video displays, transportation, electronic signs and signals, power supplies, solar inverters and wireless systems.</font></div><div style="line-height:120%;padding-top:8px;text-indent:30px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">The Company develops and manufactures semiconductor materials and devices primarily based on silicon carbide (SiC), gallium nitride (GaN) and related compounds. The physical and electronic properties of SiC and GaN offer technical advantages over traditional silicon, gallium arsenide (GaAs) and other materials used for electronic and opto-electronic applications.</font></div><div style="line-height:120%;padding-top:8px;text-indent:30px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">The Company's LED products consist of LED components, LED chips, and SiC wafers. As LED technology improves, the Company believes the potential market for LED lighting will continue to expand. The Company's success in selling LED products depends upon the ability to offer innovative products and solutions that enable its customers to develop and market LED based products that successfully compete and drive LED adoption against traditional lighting products.</font></div><div style="line-height:120%;padding-top:8px;text-indent:30px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">The Company's lighting products consist of both LED and traditional lighting systems. The Company designs, manufactures and sells lighting systems for indoor and outdoor applications, with a primary focus on LED lighting systems for the commercial and industrial markets. The Company also uses its LED systems expertise to accelerate LED lighting adoption and expand the market for its LED components.</font></div><div style="line-height:120%;padding-top:8px;text-indent:30px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">In addition, the Company develops, manufactures and sells power and RF devices. The Company's power products are made from SiC and provide faster switching speeds than comparable silicon-based power devices for a given power level.

On an ongoing basis, the Company evaluates its estimates, including those related to revenue recognition, provision for doubtful accounts, sales returns, sales price discounts and incentives, provision for inventory obsolescence, fair value of investments, fair value of acquired intangible assets and goodwill, useful lives of intangible assets and property and equipment, income taxes, product warranty obligations, employee stock options, and contingencies and litigation, among others. The Company generally bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual amounts recorded could differ materially from those estimates.</font></div></div>
