If we are unable to sell a property when we determine to do so, it could have a significant adverse effect on our cash flows that are necessary to meet our mortgage obligations and our ability to satisfy our other liabilities in the normal course of business. Our ability to continue as a going concern is dependent upon our ability to sell real estate investments, to pay down debt as it matures if extensions or new financings are unavailable, and our ability to fund ongoing costs of our Company, including our development and operating properties.

Business

Behringer Harvard Opportunity REIT I, Inc. (which may be referred to as the "Company," "we," "us," or "our") was incorporated in November 2004 as a Maryland corporation and has elected to be taxed, and currently qualifies, as a real estate investment trust ("REIT") for federal income tax purposes.

We operate commercial real estate and real estate-related assets located in and outside the United States. With our opportunistic and value-add investment strategy, we have focused generally on acquiring properties with significant possibilities for capital appreciation, such as those requiring development, redevelopment, or repositioning, or those located in markets and submarkets with higher volatility, lower barriers to entry, and high growth potential.
