FFO does not represent cash flows from operations as defined by accounting principles generally accepted in the United States, is not necessarily indicative of cash available to fund all cash flow needs and should not be considered as an alternative to net income (loss) for purposes of evaluating the Company’s operating performance or to cash flow as a measure of liquidity.
During 2012, the Company recorded a gain on investment of $45.1 million related to the acquisition of the remaining interest in Imperial Valley Mall. During 2012 and 2011, the Company recorded gains on extinguishment of debt from both continuing and discontinued operations. Considering the significance and nature of these items, the Company believes that it is important to identify their impact on its FFO measures for a reader to have a complete understanding of the Company’s results of operations. Therefore, the Company has also presented its FFO measures excluding these items.
Same-Center Net Operating Income
NOI is a supplemental measure of the operating performance of the Company's shopping centers. The Company defines NOI as operating revenues (rental revenues, tenant reimbursements and other income) less property operating expenses (property operating, real estate taxes and maintenance and repairs).Similar to FFO, the Company computes NOI based on its pro rata share of both consolidated and unconsolidated properties. The Company's definition of NOI may be different than that used by other companies and, accordingly, the Company's NOI may not be comparable to that of other companies. A reconciliation of same-center NOI to net income is located at the end of this earnings release. Since NOI includes only those revenues and expenses related to the operations of its shopping center properties, the Company believes that same-center NOI provides a measure that reflects trends in occupancy rates, rental rates and operating costs and the impact of those trends on the Company's results of operations. Additionally, there are instances when tenants terminate their leases prior to the scheduled expiration date and pay the Company one-time, lump-sum termination fees. These one-time lease termination fees may distort same-center NOI trends and may result in same-center NOI that is not indicative of the ongoing operations of the Company's shopping center properties. Therefore, the Company believes that presenting same-center NOI, excluding lease termination fees, is useful to investors.
