[1] Proportionate property net operating income, our key measurement of segment profit or loss, excludes provision for operating real estate impairment losses, property management revenues (which are included in rental and other property revenues), property management expenses and casualty gains and losses (which are included in property operating expenses) and depreciation and amortization. Accordingly, we do not allocate these amounts to our segments.
