Forward-looking statements are subject to risks, uncertainties, and assumptions about us which may cause our actual future results to differ materially from expected results. Some of the factors that could cause actual results to differ materially are, among others, our continued qualification as a real estate investment trust; general domestic and foreign business, economic, or financial conditions; competition; fluctuating interest and currency rates; inflation and its impact on our clients and us; access to debt and equity capital markets and other sources of funding (including the terms, structure and partners of such funding); volatility and uncertainty in the credit and financial markets; other risks inherent in real estate, private capital, credit and mezzanine investments, and joint ventures or co-investment ventures including solvency, defaults under leases, bankruptcies, potential liability relating to environmental matters, illiquidity of real estate investments (including rights of first refusal or rights of first offer), and potential damages from natural disasters; impairments in the value of our real estate assets; volatility and changes in domestic and foreign laws and the application, enforcement or interpretation thereof (including with respect to tax laws and rates); property ownership through co-investment ventures, funds, joint ventures, partnerships and other arrangements which, among other things, may transfer or limit our control of the underlying investments; epidemics or pandemics; the loss of key personnel; the threat and outcome of any legal proceedings to which we are a party or which may occur in the future; acts of terrorism and war; and the anticipated benefits from mergers, acquisitions, co-investment ventures, funds, joint ventures, partnerships and other arrangements; and those additional risks and factors discussed in our reports filed with the U.S. Securities and Exchange Commission.
