Income Taxes [Abstract]
Income Taxes	8. Income Taxes We elected to be taxed as a REIT under the Internal Revenue Code (“Code”), commencing with our taxable year ended December 31, 1995. To qualify as a REIT, we must meet a number of organizational and operational requirements, including a requirement that we currently distribute at least 90% of our REIT taxable income to our stockholders. The difference between net income available to common stockholders for financial reporting purposes and taxable income before dividend deductions relates primarily to temporary differences, such as real estate depreciation and amortization, deduction of deferred compensation and deferral of gains on sold properties utilizing like kind exchanges. Also, at least 95% of our gross income in any year must be derived from qualifying sources. It is our intention to adhere to these requirements and maintain our REIT status. As a REIT, we generally will not be subject to corporate level federal income tax, provided that distributions to our stockholders equal at least the amount of our REIT taxable income as defined under the Code. If we fail to qualify as a REIT in any taxable year, we will be subject to federal income taxes at regular corporate rates (including any applicable alternative minimum tax) and may not be able to qualify as a REIT for four subsequent taxable years. Even if we qualify for taxation as a REIT, we may be subject to state income or franchise taxes in certain states in which some of our properties are located and excise taxes on our undistributed taxable income. We are required to pay U.S. federal and state income taxes on our net taxable income, if any, from the activities conducted by our taxable REIT subsidiaries (“TRSs”). Accordingly, the only provision for federal income taxes in our consolidated financial statements relates to our consolidated TRSs. We recorded an income tax benefit during the three months ended June 30, 2011 and 2010 of approximately $553,000 and $926,000, respectively, and for the six months ended June 30, 2011 and 2010 of approximately $1.1 million and $2.0 million, respectively. These benefits are primarily attributable to the net operating losses generated by DIM Vastgoed, N.V. (“DIM”), a Dutch company in which we acquired a controlling interest in the first quarter of 2009. Although DIM is organized under the laws of the Netherlands, it pays U.S. corporate income tax based on its operations in the United States. Pursuant to the tax treaty between the U.S. and the Netherlands, DIM is entitled to the avoidance of double taxation on its U.S. income. Thus, it pays virtually no taxes in the Netherlands. In 2010, DIM did not pay any U.S. income tax, which reflected the benefit of net operating loss carry forwards (“NOLs”) in previous years. As of June 30, 2011, DIM had federal and state NOLs of approximately $24.1 million and $25.9 million remaining, respectively. These carry forwards begin to expire in 2027. We believe that we have appropriate support for the tax positions taken on our tax returns and that our accruals for income tax liabilities are adequate for all years still subject to tax audit after 2006.

We elected to be taxed as a REIT under the Internal Revenue Code (“Code”), commencing with our taxable year ended December 31, 1995. To qualify as a REIT, we must meet a number of organizational and operational requirements, including a requirement that we currently distribute at least 90% of our REIT taxable income to our stockholders.
