The Company's future operating results are subject to various risks and uncertainties and could differ materially from those discussed in the forward-looking statements and may be affected by various trends and factors which are beyond the Company's control. These risks and uncertainties include, among other factors, general business and economic conditions, rapid technological changes accompanied by frequent new product introductions, competitive pressures, dependence on key customers, inability to gauge order flows from customers, fluctuations in quarterly and annual results, the reliance on a limited number of third party suppliers, limitations of the Company's manufacturing capacity and arrangements, the protection of the Company's proprietary technology, the dependence on key personnel, changes in critical accounting estimates, potential impairments related to goodwill and investments, foreign regulations and potential material weaknesses in internal control over financial reporting.
