Realty Income estimates that 2013 Adjusted Funds from Operations (AFFO) should range from $2.31 to $2.37 per share, an increase of 9.5% to 15.0% over the 2012 estimated AFFO per share of $2.06 to $2.11. The AFFO per share estimate for 2013 is based on adding back items to FFO totaling $0.08 to $0.10, that reduce net income, and deducting capitalized expenditures and straight-line rent revenue items totaling approximately $0.05 to $0.07, for a net increase of $0.01 to $0.05 over FFO.Realty Income considers FFO and AFFO to be appropriate supplemental measures of a real estate investment trust’s (REIT’s) operating performance. Realty Income defines FFO consistent with the National Association of Real Estate Investment Trust’s (NAREIT’s) definition as net income available to common stockholders plus depreciation and amortization of real estate assets, reduced by gains on sales of investment properties and extraordinary items. AFFO further adjusts FFO for unique revenue and expense items which are not pertinent to the measurement of Realty Income’s ongoing operating performance.
