[1] Proportionate property net operating income, our key measurement of segment profit or loss, excludes 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), depreciation and amortization and provision for real estate impairment losses. Accordingly, we do not allocate these amounts to our segments.
