The Company’s operating results depend upon the capital and operating expenditures of integrated device manufacturers (“IDMs”), outsourced semiconductor assembly and test providers (“OSATs”), foundry service providers, and other electronics manufacturers and automotive electronics suppliers worldwide which, in turn, depend on the current and anticipated market demand for semiconductors and products utilizing semiconductors. The semiconductor industry is highly volatile and experiences downturns and slowdowns which can have a severe negative effect on the semiconductor industry’s demand for semiconductor capital equipment, including assembly equipment manufactured and sold by the Company and, to a lesser extent, tools, solutions and services, including those sold or provided by the Company. These downturns and slowdowns have in the past adversely affected the Company’s operating results.

As a result, management makes judgments regarding the carrying values of the Company’s assets and liabilities that are not readily apparent from other sources. Authoritative pronouncements, historical experience and assumptions are used as the basis for making estimates, and on an ongoing basis, management evaluates these estimates.
