Recognition of Rental Income and Tenant Recoveries. Under U.S. GAAP, we are required to recognize rental income based on the effective monthly rent for each lease. The effective monthly rent is equal to the average monthly rent during the term of the lease, not the stated rent for any particular month. The process, known as "straight-lining" rent, generally has the effect of increasing rental revenues during the early phases of a lease and decreasing rental revenues in the latter phases of a lease. If rental income calculated on a straight-line basis exceeds the cash rent due under the lease, the difference is recorded as an increase to both deferred rent receivable and rental income in the accompanying consolidated financial statements. If the cash rent due under the lease exceeds rental income calculated on a straight-line basis, the difference is recorded as a decrease to both deferred rent receivable and rental income in the accompanying consolidated financial statements. We defer recognition of contingent rental income, such as percentage/excess rent, until the specified target that triggers the contingent rental income is achieved. We periodically review the collectability of outstanding receivables. Allowances are taken for those balances that we have reason to believe will be uncollectible, including any amounts relating to straight-line rent receivables. Amounts deemed to be uncollectible are written off. Tenant recoveries are primarily comprised of real estate tax and common area maintenance reimbursement income. Real estate tax income is based on an accrual reimbursement calculated by tenant, based on an estimate of current year real estate taxes. As actual real estate tax bills are received, we reconcile with our tenants and adjust prior year income estimates in the current period. Common area maintenance income is accrued on actual common area maintenance expenses as incurred. Annually, we reconcile with the tenants for their share of the expenses per their lease and we adjust prior year income estimates in the current period. Recognition of Lease Termination Income. We accrue lease termination income if there is a signed termination agreement, all of the conditions of the agreement have been met and the tenant is no longer occupying the property. Upon early lease termination, we provide for losses related to unrecovered intangibles and other assets. Consolidation/Equity Accounting Policies. We consolidate the operations of a joint venture if we determine that we are either the primary beneficiary of a variable interest entity or have substantial influence and control of the entity. The primary beneficiary is the party that absorbs a majority of the entity's expected losses or residual returns. There are significant judgments and estimates involved in determining the primary beneficiary of a variable interest entity or the determination of who has control and influence of the entity. When we consolidate an entity, the assets, liabilities and results of operations of a variable interest entity are included in our consolidated financial statements. In instances where we are not the primary beneficiary of a variable interest entity or we do not control the joint venture, we use the equity method of accounting. Under the equity method, the operations of a joint venture are not consolidated with our operations but instead our share of operations is reflected as equity in earnings (loss) of unconsolidated joint ventures on our consolidated statements of operations and other comprehensive income. Additionally, our net investment in the joint venture is reflected as investment in and advances to joint venture as an asset on the consolidated balance sheets. Investment in Securities. We classify our investment in securities in one of three categories: trading, available-forsale, or held-to-maturity. Trading securities are bought and held principally for the purpose of selling them in the near term. Held-to-maturity securities are those securities in which we have the ability and intent to hold the security until maturity. All securities not included in trading or held-to-maturity are classified as available-for-sale. Investment in securities at December 31, 2009 and 2008 consist of perpetual preferred securities and common securities classified as available-for-sale securities, which are recorded at fair value. Unrealized holding gains and losses on securities are excluded from earnings and reported as a separate component of other comprehensive income until realized. Realized gains and losses from the sale of securities are determined on a specific identification basis. A decline in the market value of any available-for-sale security below cost that is deemed to be other than temporary, results in a reduction in the carrying amount to fair value. The impairment is charged to earnings and a new cost basis for the security is established. 47
