Forward Looking Statement This presentation contains forward-looking statements that set forth management's anticipated results based on management's current plans and assumptions. In addition, the financial results reported in this presentation continue to be subject to adjustment until filing of the Company's quarterly report on Form 10-Q for the quarter ended April 30, 2010. Any number of factors could cause the Company's actual results to differ materially from those anticipated. Factors that could cause actual results to differ include but are not limited to the following: (1) risks relating to our acquisition strategy may adversely impact our results of operations; (2) intense competition can constrain our ability to gain business, as well as our profitability; (3) we are subject to volatility associated with high deductibles for certain insurable risks; (4) an increase in costs that we cannot pass on to clients could affect our profitability; (5) we provide our services pursuant to agreements which are cancelable by either party upon 30 to 60 days' notice; (6) our success depends on our ability to preserve our long-term relationships with clients; (7) our transition to a shared services function could create disruption in functions affected; (8) we incur significant accounting and other control costs that reduce profitability; (9) a decline in commercial office building occupancy and rental rates could affect our revenues and profitability; (10) deterioration in economic conditions in general could further reduce the demand for facility services and, as a result, reduce our earnings and adversely affect our financial condition; (11) the financial difficulties or bankruptcy of one or more of our major clients could adversely affect results; (12) our ability to operate and pay our debt obligations depends upon our access to cash; (13) because ABM conducts business operations through operating subsidiaries, we depend on those entities to generate the funds necessary to meet financial obligations; (14) certain future declines or fluctuations in the fair value of our investments in auction rate securities that are deemed other-than-temporarily impaired could negatively impact our earnings; (15) uncertainty in the credit markets and the financial services industry may impact our ability to collect receivables on a timely basis and may negatively impact our cash flow; (16) any future increase in the level of debt or in interest rates can affect our results of operations; (17) an impairment charge could have a material adverse effect on our financial condition and results of operations; (18) we are defendants in several class and representative actions or other lawsuits alleging various claims that could cause us to incur substantial liabilities; (19) since we are an attractive employer for recent emigres to this country and many of our jobs are filled by such, changes in immigration laws or enforcement actions or investigations under such laws could significantly adversely affect our labor force, operations and financial results and our reputation; (20) labor disputes could lead to loss of revenues or expense variations; (21) federal health care reform legislation may adversely affect our business and results of operations; (22) we participate in multi-employer defined benefit plans which could result in substantial liabilities being incurred; and (23) natural disasters or acts of terrorism could disrupt our services. Additional information regarding these and other risks and uncertainties the Company faces is contained in the Company's Annual Report on Form 10-K for the year ended October 31, 2009 and in other reports we file from time to time with the Securities and Exchange Commission. We undertake no obligation to publicly update forward-looking statements, whether as a result of new information, future events or otherwise.
