Net Operating Income and FFOThis press release and accompanying financial information make reference to net operating income and funds from operations on a total and per share basis. Net operating income is defined as income from property operations after operating expenses have been deducted, but prior to deducting financing, administrative, fair value adjustments and income tax expenses. Brookfield Office Properties defines FFO attributable to common shareholders as income before fair value adjustments, income taxes and certain other non-cash items as and when they arise, less non-controlling interests in the foregoing. FFO is determined as FFO from consolidated properties, FFO from equity accounted investments and FFO from discontinued operations. The company uses net operating income and FFO to assess its operating results. Net operating income is important in assessing operating performance and FFO is a widely-used measure to analyze real estate. The company provides the components of net operating income and a full reconciliation from net income to FFO with the financial information accompanying this press release. The company reconciles FFO to net income as opposed to cash flow from operating activities as it believes net income is the most comparable measure. Net operating income and FFO are both measures which do not have any standard meaning and therefore may not be comparable to similar measures presented by other companies.
