Dividends Declared

Our board of directors declared a quarterly cash dividend on our common stock of $0.17 per share, or $0.68 per share on an annualized basis. The fourth quarter dividend will be payable February 28, 2014 to shareholders of record on February 14, 2014. The board also declared the following dividends on our outstanding preferred stock:

Completion of Long-Term Asset and Capital Strategies Begun in 2009

The company also announced that it had reached its target asset allocation and achieved its previously specified leverage goals at December 31, 2013 in accordance with its original time line. When the strategy was announced in the Fall of 2009, the company’s asset mix as represented by share of property net operating income was 56 percent suburban office and 36 percent industrial. Today, the asset mix is 60 percent bulk industrial, 25 percent suburban office and 15 percent medical office, in accordance with the original target allocation. On the capital strategy side, debt plus preferred to gross assets is now at 50 percent, the ratio of debt plus preferred to EBITDA is below 7.75 times and fixed charge coverage is at 2.3 times.

“We are pleased that we were able to timely execute on our strategies during the last four years” Mr. Oklak stated. “This effort is a credit to our great team at Duke Realty and we now have the highest quality assets in each product type and are in an excellent position to grow the company through new development opportunities as reflected by our strong 2013 development activity. In addition, I am particularly pleased that during this re-positioning we still grew our Core AFFO per share from $0.82 in 2012 to $0.90 in 2013.”

2014 Earnings Guidance

Commenting on the company’s 2014 outlook, Mr. Oklak stated: “We are introducing 2014 guidance for Core FFO of $1.11 to $1.19 per share, and Core AFFO of $0.91 to $0.97 per share. The growth from 2013 to 2014 anticipates continued strong performance in our operating portfolio, deliveries of our highly leased development pipeline and continued property dispositions from our suburban office portfolio. We are coming off an excellent year in 2013 and are well positioned for continued strong momentum in 2014.”

The assumptions underlying the guidance are as follows:

1. Continued strong occupancy performance;

2. Same property net operating income growth;

3. Deliveries of highly leased projects from our development pipeline;

4. Continued dispositions of primarily suburban office properties with proceeds used to fund new development opportunities and acquisitions.

More specific assumptions and components of 2014 Core FFO will be available by 6:00 p.m. Eastern Time today through the Investor Relations-Financials section of the company’s web-site.

FFO and AFFO Reporting Definitions

FFO: FFO is computed in accordance with standards established by 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 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 gains on sale of undeveloped land, 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.

AFFO: AFFO is defined by the company as Core FFO (as defined above), less recurring building improvements and total 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) related to leases commencing during the reporting period 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 December 31, 2013 supplemental information.
