Statements in this press release which are not historical may be deemed forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Such forward-looking statements relate to, without limitation, the Company's future economic performance, plans and objectives for future operations and projections of revenue and other financial items. Forward-looking statements can be identified by the use of words such as "may," "will," "should," "expect," "anticipate," "estimate," "continue" or comparable terminology. Although the Company believes the expectations reflected in any forward-looking statements are based on reasonable assumptions, it can give no assurance that its expectations will be attained. Forward-looking statements are inherently subject to certain risks, trends and uncertainties, many of which the Company cannot predict with accuracy and some of which the Company might not even anticipate. Future events and actual results, financial and otherwise, may differ materially from the results discussed in the forward-looking statements. You are cautioned not to place undue reliance on these forward-looking statements. Factors that could cause actual results to differ materially from the Company's expectations include the availability and cost of capital for future investments, the Company's ability to lease or re-lease space at current or anticipated rents, changes in the supply of and demand for the Company's properties, changes in interest rate levels, risks associated with the development, acquisition or disposition of properties, competition within the industry, real estate and market conditions, and other risks detailed from time to time in the Company's SEC filings. The Company assumes no obligation to update or supplement forward-looking statements that become untrue because of subsequent events.
