"Safe Harbor" Statement under the Private Securities Litigation Reform Act of 1995: Any statements set forth in the news release that are not entirely historical and factual in nature are forward-looking statements, including without limitation statements concerning Microsemi's net sales and earnings guidance, the expectations of rising customer engagements, market share gains, revenue growth, achieving margin targets, increasing cash flow and any other statements or beliefs regarding Microsemi's plans or expectations. These forward-looking statements are based on Microsemi's current expectations and are inherently subject to risks and uncertainties that could cause actual results to differ materially from those expressed in the forward-looking statements. The potential risks and uncertainties include, but are not limited to, such factors as continued negative or worsening worldwide economic conditions or market instability; risks related to Microsemi's international operations and sales, including divergent laws and regulations, political instability, trade restrictions and sanctions, restrictions in the transfer or repatriation of funds, currency fluctuations and availability of transportation services; downturns in the highly cyclical semiconductor industry that may cause us to trigger financial covenants in our debt agreements, increase the cost of borrowing, and decrease the amount available under our credit facilities; our ability to successfully implement our acquisitions and divestitures strategy or integrate acquired companies; uncertainty as to the future profitability of acquired businesses, and delays in the realization of, or the failure to realize, any accretion from acquisition transactions; acquiring, managing and integrating new operations, businesses or assets, and the associated diversion of management attention or other related costs or difficulties; difficulties and costs of protecting patents and other proprietary rights; Microsemi's reliance on government contracts for a significant portion of its sales, including impacts of any termination or renegotiation of such contracts, uncertainties of governmental appropriations and national defense policies and priorities and effects of any past or future government shutdowns; potential non-realization of expected orders or non-realization of backlog; failure to make sales indicated by the Microsemi's book-to-bill ratio; intense competition in the semiconductor industry and resultant downward price pressure; the effect of events such as natural disasters and related disruptions on our operations; the concentration of the facilities that service the semiconductor industry; delays in beginning production, implementing production techniques, resolving problems associated with technical equipment malfunctions, or issues related to government or customer qualification of facilities; our dependence on third parties for key functions; utilization of channel partners over which we have limited control for product distribution; increases in the costs of credit and the availability of credit or additional capital only under more restrictive conditions or not at all; changes to laws or regulations, including tax laws or regulations; unanticipated changes in Microsemi's tax obligations, results of tax examinations or exposure to additional income tax liabilities; changes in generally accepted accounting principles; principal, liquidity and counterparty risks related to Microsemi's holdings in securities; inability to develop new technologies and products to satisfy changes in customer demand or the development by our competitors of products that decrease the demand for Microsemi's products; unfavorable or declining conditions in end markets; inability of Microsemi's compound semiconductor products to compete successfully with silicon-based products; production delays related to new compound semiconductors; variability of our manufacturing yields; potential effects of system outages or data security breaches; inability by Microsemi to fulfill customer demand and resulting loss of customers; variations in customer order preferences; difficulties foreseeing future demand; rises in inventory levels and inventory obsolescence; environmental or other regulatory matters or litigation, or any matters involving contingent liabilities or other claims; the uncertainty of litigation, the costs and expenses of litigation, the potential material adverse effect litigation could have on Microsemi's business and results of operations if an adverse determination in litigation is made, and the time and attention required of management to attend to litigation; difficulties in determining the scope of, and procuring and maintaining, adequate insurance coverage; difficulties in the hiring and retention of qualified personnel in a competitive labor market; any circumstances that adversely impact the end markets of acquired businesses; and difficulties in closing or disposing of operations or assets or transferring work, assets or inventory from one plant to another. In addition to these factors and any other factors mentioned elsewhere in this news release, the reader should refer as well to the factors, uncertainties or risks identified in Microsemi's most recent Annual Report on Form 10-K and any subsequent Quarterly Reports on Form 10-Q reports filed by Microsemi with the SEC.
