SEGMENT INFORMATION

Our operations are organized into five operating segments which are regularly reviewed by our CODM for the purpose of allocating resources to the segment and to assess its performance. The key measures used by the CODM in assessing performance and in making resource allocation decisions are company funds from operations, or Company FFO, and Company EBITDA.

Company FFO is calculated as net income excluding the impact of depreciation and amortization, deferred income taxes, breakage and transaction costs, non-cash valuation gains or losses and other items. When determining Company FFO, we include our proportionate share of Company FFO of equity accounted investments.

Company FFO is further adjusted as Company EBITDA to exclude the impact of realized disposition gains (losses), interest expenses, current income taxes, and realized disposition gains, current income taxes and interest expenses related to equity accounted investments.
