ROIC computes FFO in accordance with the "White Paper" on FFO published by NAREIT, which defines FFO as net income attributable to common shareholders (determined in accordance with GAAP) excluding gains or losses from debt restructuring and sales of property and impairments, plus real estate related depreciation and amortization, and after adjustments for partnerships and unconsolidated joint ventures. FFO as defined by ROIC may not be comparable to similarly titled items reported by other real estate investment trusts due to possible differences in the application of the NAREIT definition used by such REITs.
