Financial Performance

• Core FFO for the second quarter of 2013 of $0.27 per share compared with $0.26 per share for the second quarter of 2012. Overall Core FFO increased from the second quarter of 2012 due to improved rental operations and lower general and administrative expenses. A reconciliation of FFO as defined by NAREIT to Core FFO is included in the financial tables included in this release.

• FFO as defined by NAREIT was $0.25 per share for the second quarters of 2013 and 2012. In addition to the factors driving Core FFO performance, FFO as defined by NAREIT was lower during the second quarter of 2013 because of an impairment charge on a land sale and acquisition-related costs. A reconciliation of FFO as defined by NAREIT to Core FFO is included in the financial tables included in this release.

• Net earnings of $0.19 per diluted share for the second quarter of 2013 compared to net loss of $0.11 per diluted share for the same quarter in 2012. The improvement in earnings per share was primarily the result of gains on sales of properties during the second quarter of nearly $85 million, driven primarily by the aforementioned retail property sale.

FFO and AFFO Reporting Definitions

Funds from Operations (“FFO”): FFO is computed in accordance with standards established by the National Association of Real Estate Investment Trusts (“NAREIT”). NAREIT defines FFO as net income (loss) excluding gains (losses) on sales of depreciable property, impairment charges related to depreciable real estate assets, and extraordinary items (computed in accordance with generally accepted accounting principles (“GAAP”)); plus real estate related depreciation and amortization, and after similar adjustments for unconsolidated joint ventures. The company believes FFO to be most directly comparable to net income as defined by GAAP. The company believes that FFO should be examined in conjunction with net income (as defined by GAAP) as presented in the financial statements accompanying this release. FFO does not represent a measure of liquidity, nor is it indicative of funds available for the company’s cash needs, including the company’s ability to make cash distributions to shareholders.

Core Funds from Operations (“Core FFO”): Core FFO is computed as FFO adjusted for certain items that are generally non-cash in nature and that materially distort the comparative measurement of company performance over time. The adjustments include impairment charges not related to depreciable real estate assets, tax expenses or benefit related to (i) changes in deferred tax asset valuation allowances, (ii) changes in tax exposure accruals that were established as the result of the adoption of new accounting principles, or (iii) taxable income (loss) related to other items excluded from FFO or Core FFO (collectively referred to as “other income tax items”), gains (losses) on debt transactions, adjustments on the repurchase or redemption of preferred stock, gains (losses) on and related costs of acquisitions, and severance charges related to major overhead restructuring activities. Although the company’s calculation of Core FFO differs from NAREIT’s definition of FFO and may not be comparable to that of other REITs and real estate companies, the company believes it provides a meaningful supplemental measure of its operating performance.

Adjusted Funds from Operations (“AFFO”): AFFO is defined by the company as Core FFO (as defined above), less recurring building improvements and second generation capital expenditures (the leasing of vacant space that had previously been under lease by the company is referred to as second generation lease activity) and adjusted for certain non-cash items including straight line rental income, non-cash components of interest expense and stock compensation expense, and after similar adjustments for unconsolidated partnerships and joint ventures.

Same Property Performance

The company includes same-property net operating income growth as a property-level supplemental measure of performance. The company does not believe same-property net operating income growth to be a primary measure of overall company operating performance. The company utilizes same-property net income

growth as a supplemental measure to evaluate property-level performance, without differentiating or making adjustment as to whether a property is consolidated or jointly controlled.

A description of the properties that are excluded from the company’s same-property measure is included on page 22 of our June 30, 2013 supplemental information.
