The actual results could differ materially from those discussed. Factors that could contribute to such differences include the following: a decline in either the growth of wireless communications or the acceptance of CDMA technology; the demand for semiconductors for applications such as optical networks and wireless communication and the performance of our manufacturing facilities; our ability to successfully integrate the combined company; our dependence on a few large customers; competitive products or technologies that could reduce demand for our products such as direct conversion or digital filtering technology; increased sales through consignment agreements; our ability to successfully develop and bring new products to market; our dependence on a limited number of suppliers for certain key raw materials; risks associated with international sales; declining selling prices for some of our key products; decreased manufacturing yields; cancellation of purchase orders by our customers; our inability to protect our intellectual property or if we infringe on the intellectual property of others; increased competition from other suppliers; risks associated with our Costa Rican operations; risk of natural disasters, and other risks discussed in the SEC filings of the respective companies including Form 10-K and Form 10-Q, which can be accessed at the SEC website at www.sec.gov.
