Summary Of Significant Accounting Policies

Principles of Consolidation

Principles of Consolidation

Our consolidated financial statements include the accounts of the Trust, its corporate subsidiaries, and all entities in which the Trust has a controlling interest or has been determined to be the primary beneficiary of a variable interest entity ("VIE"). The equity interests of other investors are reflected as noncontrolling interests. All significant intercompany transactions and balances are eliminated in consolidation. We account for our interests in joint ventures, which we do not control or manage, using the equity method of accounting. Certain 2010 amounts have been reclassified to conform to current period presentation.

Use of Estimates

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America, referred to as "GAAP," requires management to make estimates and assumptions that in certain circumstances affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities, and revenues and expenses. These estimates are prepared using management's best judgment, after considering past, current and expected events and economic conditions. Actual results could differ from these estimates.

Acquisition Of Real Estate

Acquisition of Real Estate

Our methodology of allocating the cost of acquisitions to assets acquired and liabilities assumed is based on estimated fair values, replacement cost and appraised values. When we acquire operating real estate properties, the purchase price is allocated to land, building, improvements, intangibles such as in-place leases, and to current assets and liabilities acquired, if any. The value allocated to in-place leases is amortized over the related lease term and reflected as rental income in the statement of operations. We consider qualitative and quantitative factors in evaluating the likelihood of a tenant exercising a below market renewal option and include such renewal options in the calculation of in-place lease value when we consider these to be bargain renewal options. If the value of below market lease intangibles includes renewal option periods, we include such renewal periods in the amortization period utilized. If a tenant vacates its space prior to contractual termination of its lease, the unamortized balance of any in-place lease value is written off to rental income.
