The following frequently used abbreviations or acronyms are used in this Annual Report on Form 10-K as defined below:

Forward-Looking and Cautionary Statements

This Annual Report on Form 10-K contains certain statements that are, or may be deemed to be, "forward-looking statements" within the meaning of Section 27A of the Securities Act and Section 21E of the Exchange Act. The Private Securities Litigation Reform Act of 1995 provides safe harbor provisions for forward-looking information. Some of the statements contained in this Annual Report on Form 10-K are forward-looking statements. All statements other than statements of historical fact are, or may be deemed to be, forward-looking statements. The words "believe," "may," "estimate," "continue," "anticipate," "intend," "plan," "expect" and similar expressions are intended to identify forward-looking statements. Forward-looking statements include information concerning our possible or assumed future financial performance and results of operations, and include information related to the proposed spin-off of our Mission Technology Solutions business into a stand-alone, publicly traded company.

We have based these statements on our assumptions and analyses in light of our experience and perception of historical trends, current conditions, expected future developments and other factors we believe are appropriate in the circumstances. Forward-looking statements by their nature involve substantial risks and uncertainties that could significantly affect expected results, and actual future results could differ materially from those described in such statements. While it is not possible to identify all factors, factors that could cause actual future results to differ materially include the risks and uncertainties disclosed under “Item 1A. Risk Factors” contained in Part I and other relevant sections of this Annual Report on Form 10-K.

Many of these factors are beyond our ability to control or predict. Any of the following factors, as well as the risks and uncertainties disclosed under “Item 1A. Risk Factors” contained in Part I of this Annual Report on Form 10-K, and the risk factors and other cautionary statements contained in our other filings with the SEC, or a combination of these factors, could materially and adversely affect our future financial condition or results of operations and the ultimate accuracy of the forward-looking statements. These forward-looking statements are not guarantees of our future performance, and our actual results and future developments may differ materially and adversely from those projected in the forward-looking statements. We caution against putting undue reliance on forward-looking statements or projecting any future results based on such statements or on present or prior earnings levels. In addition, each forward-looking statement speaks only as of the date of the particular statement, and we undertake no obligation to publicly update or revise any forward-looking statement.

Summary Risk Factors

The following is a summary of some of the risks and uncertainties that could materially adversely affect our business, financial condition and results of operations. This summary should be read together with the more detailed description of each risk factor disclosed under "Item 1A. Risk Factors" contained in Part I of this Annual Report on Form 10-K.
