The consolidated financial statements include the accounts of COPT, the Operating Partnership, their subsidiaries and other entities in which we have a majority voting interest and control.  We also consolidate certain entities when control of such entities can be achieved through means other than voting rights (“variable interest entities” or “VIEs”) if we are deemed to be the primary beneficiary of such entities.  We eliminate all significant intercompany balances and transactions in consolidation.

We use the equity method of accounting when we own an interest in an entity and can exert significant influence over the entity’s operations but cannot control the entity’s operations.

We use the cost method of accounting when we own an interest in an entity and cannot exert significant influence over its operations.

These interim financial statements should be read together with the financial statements and notes thereto as of and for the year ended December 31, 2011 included in our 2011 Annual Report on Form 10-K.  The unaudited consolidated financial statements include all adjustments that are necessary, in the opinion of management, to fairly present our financial position and results of operations.  All adjustments are of a normal recurring nature.  The consolidated financial statements have been prepared using the accounting policies described in our 2011 Annual Report on Form 10-K.

We assess each of our operating properties for impairment quarterly using cash flow projections and estimated fair values that we derive for each of the properties.  We update the leasing and other assumptions used in these projections regularly, paying particular attention to properties that have experienced chronic vacancy or face significant market challenges.  We review our plans and intentions for our development projects and land parcels quarterly.  Each quarter, we also review the reasonableness of changes in our estimated operating property fair values from amounts estimated in the prior quarter.  If events or changes in circumstances indicate that the carrying values of certain operating properties, properties in development or land held for future development may be impaired, we perform a recovery analysis for such properties.  For long-lived assets to be held and used, we analyze recoverability based on the estimated undiscounted future cash flows expected to be generated from the operations and eventual disposition of the assets over, in most cases, a ten-year holding period.  If we believe there is a significant possibility that we might dispose of the assets earlier, we analyze recoverability using a probability weighted analysis of the estimated undiscounted future cash flows expected to be generated from the operations and eventual disposition of the assets over the various possible holding periods.  If the recovery analysis indicates that the carrying value of a tested property is not recoverable from estimated future cash flows, it is written down to its estimated fair value and an impairment loss is recognized.  If and when our plans change, we revise our recoverability analyses to use the cash flows expected from the operations and eventual disposition of each asset using holding periods that are consistent with our revised plans.

Property fair values are determined based on contract prices, indicative bids, discounted cash flow analyses or yield analyses. The estimated cash flows used are based on our plans for the property and our views of market and economic conditions. The estimates consider items such as current and future rental rates, occupancies for the tested property and comparable properties, estimated operating and capital expenditures and recent sales data for comparable properties; most of these items are influenced by market data obtained from third party sources such as CoStar Group and real estate leasing and brokerage firms and our direct experience with the properties and their markets.
