These forward-looking statements relate to anticipated financial performance, management’s plans and objectives for future operations, business prospects, outcome of regulatory proceedings, market conditions and other matters. We make these forward-looking statements in reliance on the safe harbor protections provided under the Private Securities Litigation Reform Act of 1995. All statements, other than statements of historical facts, included in this press release that address activities, events or developments that we expect, believe or anticipate will exist or may occur in the future, are forward-looking statements.

These forward-looking statements are based on management’s current beliefs and assumptions and on information currently available to management that are subject to risks and uncertainties, many of which are outside of our control,

and could cause future events or results to be materially different from those stated or implied in this press release. Specific factors that could cause actual results to differ from results contemplated by forward-looking statements include, among others, the following: competition in the markets we serve, including new entrants in these markets; our ability to develop or acquire new technology; failure to maintain the security of our information and technology networks; allegations that we have infringed the intellectual property rights of third parties; unauthorized use of our brand name; risks associated with ownership of the ADT^® brand name outside of the United States and Canada by Tyco International Ltd., our former parent (“Tyco”); failure to enforce our intellectual property rights; our dependence on certain software technology that we license from third parties; failure or interruption in products or services of third-party providers; our greater exposure to liability for employee acts or omissions or system failures; an increase in the rate of customer attrition; downturns in the housing market and consumer discretionary income; risks associated with our non-compete and non-solicit arrangements with Tyco; entry of potential competitors upon the expiration of non-competition agreements; shifts in consumers’ choice of, or telecommunication providers’ support for, telecommunication services and equipment; interruption to our monitoring facilities; interference with our customers’ access to some of our products and services through the Internet by broadband service providers; potential impairment of our deferred tax assets; changes in U.S. and non-U.S. governmental laws and regulations; risks associated with acquiring and integrating customer accounts; potential loss of authorized dealers and affinity marketing relationships; failure to realize expected benefits from acquisitions; risks associated with pursuing business opportunities that diverge from our current business model; potential liabilities for obligations of The Brink’s Company under the Coal Act; potential liabilities for legacy obligations relating to the separation from Tyco; capital market conditions, including availability of funding sources; risks related to our increased indebtedness; changes in our credit ratings; failure to fully realize expected benefits from the separation from Tyco; and difficulty in operating as an independent public company separate from Tyco. Given the risk factors and uncertainties that could cause our actual results to differ materially from those contained in any forward-looking statement, we caution investors not to unduly rely on our forward-looking statements. These risk factors should not be construed as exhaustive. We disclaim any obligations to and do not intend to update the risk factors listed herein or to announce publicly the result of any revisions to any of the forward-looking statements to reflect future events or developments. If one or more of these risks or uncertainties materialize or if our underlying assumptions prove to be incorrect, actual results may vary materially from what we projected. Consequently, actual events and results may vary significantly from those included in or contemplated or implied by our forward-looking statements.
