Piedmont Office Realty Trust Reports First Quarter Results

ATLANTA, May 2, 2013 --Piedmont Office Realty Trust, Inc. ("Piedmont" or the "Company") (NYSE:PDM), an owner of primarily Class A properties located predominantly in the ten largest U.S. office markets, today announced its results for the quarter ended March 31, 2013.

Highlights for the Three Months Ended March 31, 2013:

• Achieved Core Funds From Operations ("CFFO") of $0.37 per diluted share for the quarter;

• Purchased two properties in our concentration markets;

• Disposed of one non-core asset and contracted to sell another opportunistic investment;

• Completed 487,000 square feet of leasing.

Donald A. Miller, CFA, President and Chief Executive Officer stated, “We executed well this quarter from a transactional perspective. We bought two Class A properties in our targeted concentration markets, disposed of another non-core asset, and locked in value creation for our stockholders through the sale of 1200 Enclave. At the same time, we also delivered solid operational results. Although our leasing activity was lighter than it has been for the last several quarters, we feel good about the pipeline for the remainder of 2013.”

Results for the Three Months Ended March 31, 2013

Piedmont's net income available to common stockholders for the first quarter of 2013 was $14.7 million, or $0.09 per diluted share, as compared with $37.2 million, or $0.22 per diluted share, for the first quarter of 2012. The first quarter results of the prior year included $17.8 million, or $0.10 per diluted share, in gain on sale associated with properties that were sold during the three months ended March 31, 2012. The current quarter includes a $6.4 million, or $0.04 per diluted share, impairment loss recognized in conjunction with the write-down in value and subsequent sale of the 1111 Durham Avenue property. Income from continuing operations increased from $0.11 per diluted share for the three months ended March 31, 2012 to $0.13 per diluted share for the three months ended March 31, 2013.

Revenues for the quarter ended March 31, 2013 were $134.3 million, as compared with $131.1 million for the same period a year ago, primarily reflecting increased revenues associated with the commencement of several significant leases over the previous twelve months as well as the acquisition of two additional properties during the quarter ended March 31, 2013.

Property operating costs were $52.9 million for the quarter ended March 31, 2013, which was comparable to the prior period of $51.7 million. General and administrative expense decreased approximately $0.7 million compared to the previous year's first quarter primarily due to a decrease in legal expense.

Funds From Operations ("FFO") for the current quarter totaled $60.2 million, or $0.36 per diluted share, as compared with $60.0 million, or $0.35 per diluted share, for the quarter ended March 31, 2012. The prior year's first quarter included $0.01 per diluted share in FFO contribution associated with eight properties that were sold subsequent to January 1, 2012.

Core FFO, which primarily excludes transaction costs associated with two acquisitions made during the quarter, totaled $61.6 million, or $0.37 per diluted share, for the current quarter, as compared to $60.0 million, or $0.35 per diluted share, for the quarter ended March 31, 2012. The first quarter of 2012 included $0.01 per diluted share in Core FFO contribution associated with eight properties that were sold subsequent to January 1, 2012.

Adjusted FFO (“AFFO”) for the first quarter of 2013 totaled $36.6 million, or $0.22 per diluted share, as compared to $50.1 million, or $0.29 per diluted share, in the first quarter of 2012, reflecting increased capital expenditures associated with re-tenanting certain properties.

Leasing Update

During the first quarter of 2013, the Company executed approximately 487,000 square feet of leasing throughout its markets. Of the leases signed during the quarter, approximately 367,000 square feet, or 75%, was renewal-related and 120,000 square feet, or 25%, was with new tenants.

Same store net operating income (on a cash basis) for the quarter of $75.5 million was comparable to the quarter ended March 31, 2012. As of March 31, 2013, the Company had approximately 0.4 million square feet of signed leases that have yet to commence for vacant spaces and an additional 2.0 million square feet of commenced leases that were in some form of abatement.

The Company's overall portfolio was 86.0% leased as of March 31, 2013, with a weighted average lease term remaining of approximately 7.1 years, a 6 month increase from a year ago. The stabilized portfolio was 88.9% leased as of March 31, 2013 as compared to 87.5% leased as of March 31, 2012. Details outlining Piedmont's significant upcoming lease expirations and the status of current leasing activity can be found in the Company's quarterly supplemental information package.

Capital Markets, Financing and Other Activities

As previously announced, during the three months ended March 31, 2013, Piedmont acquired two properties, Arlington Gateway in the Washington D.C. office market and 5&15 Wayside Road in the Boston market.

Arlington Gateway is a twelve-story, Class-A office property located at 901 North Glebe Road in Arlington, VA. Piedmont acquired the 334,000 square foot office building for approximately $175.6 million or $526 per square foot. Constructed in 2005, this LEED Gold and Energy Star Certified trophy property is located on the Metro line in the desirable Rosslyn-Ballston Corridor and is 99% leased exclusively to non-government tenants.

5 & 15 Wayside Road is a Class-A office project located in Burlington, Massachusetts. The 271,000 square foot office complex is comprised of two interconnected, four-story and five-story office buildings constructed in 1999 and 2001. The complex is currently 95% leased to three tenants.

Additionally during the quarter, Piedmont disposed of 1111 Durham Avenue, a non-core asset located in South Plainfield, NJ.  A long-term lease expired during the first quarter of 2013, and after assessing the aged building (constructed in 1975) and leasing prospects, Piedmont determined that the sale price should appropriately represent the land value of the asset. As a result, Piedmont disposed of the 1111 Durham Avenue building for a gross sale price of approximately $4.0 million, exclusive of closing costs. The

Company recognized a $6.4 million, non-cash impairment charge in conjunction with reclassifying the asset to held-for-sale.

Finally, during the first quarter, Piedmont entered into a contract to sell 1200 Enclave Parkway for approximately $48.8 million, or $326 per square foot. Piedmont acquired this property in early 2011 for $18.5 million. The 150,000 square foot building was constructed in 1999 and was approximately 18% leased when acquired. During 2012, we completed two leases with Schlumberger Technology Corporation which effectively leased 97% of the building to a credit-worthy tenant through 2024. The sale was completed on May 1, 2013.

Piedmont's gross assets amounted to $5.5 billion as of March 31, 2013. Total debt was approximately $1.7 billion as of March 31, 2013 as compared to $1.4 billion as of December 31, 2012. The Company's total debt-to-gross assets ratio was 30.8% as of March 31, 2013 as compared with 27.2% as of December 31, 2012. Net debt to annualized core EBITDA ratio was 5.2 x and the Company`s fixed charge coverage ratio was 4.8 x times. As of March 31, 2013, Piedmont had cash and capacity on its unsecured line of credit of approximately $86.2 million.

Subsequent to Quarter End

Dividend

On May 2, 2013, the Board of Directors of Piedmont declared a dividend for the second quarter of 2013 in the amount of $0.20 per common share outstanding to stockholders of record as of the close of business on May 31, 2013. Such dividends are to be paid on June 21, 2013.

Guidance for 2013

Based on management's expectations, the Company affirms its previous financial guidance for full-year 2013 as follows:

Low    High

Net Income                        $80 --    98 Million

Add: Depreciation and Amortization            $155 -- 160 Million

Deduct: Estimated Insurance Recoveries        $10 -- 15 Million

Core FFO                        $225 -    243 Million

Core FFO per diluted share                $1.35 - $1.45

These estimates reflect management's view of current market conditions and incorporate certain economic and operational assumptions and projections such as the move out of two governmental tenants and the decrease in net operations as a result of the sale of seven assets during 2012. This annual guidance includes the continued repositioning of the portfolio with estimated dispositions and acquisitions approximating $300 million and $400 million, respectively, during 2013. Actual results could differ from these estimates. Note that individual quarters may fluctuate on both a cash basis and an accrual basis due to lease commencements and expirations, the timing of repairs and maintenance, capital expenditures, capital markets activities and one-time revenue or expense events. In addition, the Company's guidance is based on information available to management as of the date of this release.

Non-GAAP Financial Measures

This release contains certain supplemental non-GAAP financial measures such as FFO, AFFO, Core FFO, Same store net operating income, and Core EBITDA. See below for definitions and reconciliations of these metrics to their most comparable GAAP metric.

The Company intends for all such forward-looking statements to be covered by the safe-harbor provisions for forward-looking statements contained in Section 27A of the Securities Act and Section 21E of the Exchange Act, as applicable. Such information is subject to certain risks and uncertainties, as well as known and unknown risks, which could cause actual results to differ materially from those projected or anticipated. Therefore, such statements are not intended to be a guarantee of the Company`s performance in future periods. Such forward-looking statements can generally be identified by our use of forward-looking terminology such as "may," "will," "expect," "intend," "anticipate," "believe," "continue" or similar words or phrases that are

predictions of future events or trends and which do not relate solely to historical matters. Examples of such statements in this press release include the Company`s expected leasing pipeline and estimated range of Net Income, Depreciation and Amortization, Insurance Recoveries, Core FFO and Core FFO per diluted share for the year ending December 31, 2013.  

The following are some of the factors that could cause the Company`s actual results and its expectations to differ materially from those described in the Company`s forward-looking statements: market and economic conditions remain challenging and the demand for office space, rental rates and property values may continue to lag the general economic recovery causing the Company's business, results of operations, cash flows, financial condition and access to capital to be adversely affected or otherwise impact performance, including the potential recognition of impairment charges; the success of the Company's real estate strategies and investment objectives, including the Company's ability to identify and consummate suitable acquisitions; lease terminations or lease defaults, particularly by one of the Company's large lead tenants; the impact of competition on the Company's efforts to renew existing leases or re-let space on terms similar to existing leases; changes in the economies and other conditions of the office market in general and of the specific markets in which the Company operates, particularly in Chicago, Washington, D.C., and the New York metropolitan area; economic and regulatory changes, including accounting standards, that impact the real estate market generally; additional risks and costs associated with directly managing properties occupied by government tenants; adverse market and economic conditions may continue to adversely affect the Company and could cause the Company to recognize impairment charges or otherwise impact the Company's performance; availability of financing and the Company's lending banks' ability to honor existing line of credit commitments; costs of complying with governmental laws and regulations; uncertainties associated with environmental and other regulatory matters; potential changes in political environment and reduction in federal and/or state funding of the Company's governmental tenants; the Company may be subject to litigation, which could have a material adverse effect on the Company's financial condition; the Company's ability to continue to qualify as a real estate investment trust under the Internal Revenue Code; and other factors detailed in the Company`s most recent Annual Report on Form 10-K for the period ended December 31, 2012, and other documents the Company files with the Securities and Exchange Commission.

⁽¹⁾ Includes adjustments for consolidated properties, including discontinued operations, and for our proportionate share of amounts attributable to unconsolidated joint ventures.

⁽²⁾ Excludes depreciation of non real estate assets.

⁽³⁾ Capital expenditures of a recurring nature related to tenant improvements and leasing commissions that do not incrementally enhance the underlying assets' income generating capacity. Tenant improvements, leasing commissions, building capital and deferred lease incentives incurred to lease space that was vacant at acquisition, leasing costs for spaces vacant for greater than one year, leasing costs for spaces at newly acquired properties for which in-place leases expire shortly after acquisition, improvements associated with the expansion of a building and renovations that change the underlying classification of a building are excluded from this measure.

*Definitions

Funds From Operations ("FFO"): FFO is calculated in accordance with the current National Association of Real Estate Investment Trusts ("NAREIT") definition. NAREIT currently defines FFO as net income (computed in accordance with GAAP), excluding gains or losses from sales of property and impairment losses, adding back depreciation and amortization on real estate assets, and after the same adjustments for unconsolidated partnerships and joint ventures. These adjustments can vary among owners of identical assets in similar conditions based on historical cost accounting and useful-life estimates. FFO may provide valuable comparisons of operating performance between periods and with other REITs. FFO is a non-GAAP financial measure and should not be viewed as an alternative measurement of our operating performance to net income. We believe that FFO is a beneficial indicator of the performance of an equity REIT.

However, other REITs may not define FFO in accordance with the NAREIT definition, or may interpret the current NAREIT definition differently than we do; therefore, our computation of FFO may not be comparable to that of such other REITs.

Core Funds From Operations ("Core FFO"): We calculate Core FFO by starting with FFO, as defined by NAREIT, and adjusting for certain non-recurring items such as gains or losses on the early extinguishment of debt, acquisition-related costs and other significant non-recurring items. Such items create significant earnings volatility. We believe Core FFO provides a meaningful measure of our operating performance and more predictability regarding future earnings potential. Core FFO is a non-GAAP financial measure and should not be viewed as an alternative measurement of our operating performance to net income; therefore, it should not be compared to other REITs' equivalent to Core FFO.

Adjusted Funds From Operations ("AFFO"): AFFO is calculated by deducting from Core FFO non-incremental capital expenditures and acquisition-related costs and adding back non-cash items including non-real estate depreciation, straight lined rents and fair value lease revenue, non-cash components of interest expense and compensation expense, and by making similar adjustments for unconsolidated partnerships and joint ventures. Although AFFO may not be comparable to that of other REITs, we believe it provides a meaningful indicator of our ability to fund cash needs and to make cash distributions to equity owners. AFFO is a non-GAAP financial measure and should not be viewed as an alternative measurement of our operating performance to net income, as an alternative to net cash flows from operating activities or as a measure of our liquidity.

*Definitions

Core EBITDA: Core EBITDA is defined as net income before interest, taxes, depreciation and amortization and incrementally removing any impairment losses, gains or losses from sales of property, or other significant non-recurring items. We do not include impairment losses in this measure because we feel these types of losses create volatility in our earnings and make it difficult to determine the earnings generated by our ongoing business. We believe Core EBITDA is a reasonable measure of our liquidity. Core EBITDA is a non-GAAP financial measure and should not be viewed as an alternative measurement of cash flows from operating activities or other GAAP basis liquidity measures. Other REITs may calculate Core EBITDA differently and our calculation should not be compared to that of other REITs.

Property Net Operating Income ("Property NOI"): Property NOI is defined as real estate operating income with the add-back of corporate general and administrative expense, depreciation and amortization, and impairment losses and the deduction of income and expense associated with lease terminations and income associated with property management performed by Piedmont for other organizations. We present this measure on an accrual basis and a cash basis, which eliminates the effects of straight lined rents and fair value lease revenue. The Company uses this measure to assess its operating results and believes it is important in assessing operating performance. Property NOI is a non-GAAP measure which does not have any standard meaning prescribed by GAAP and therefore may not be comparable to similar measures presented by other companies.

Same Store Net Operating Income ("Same Store NOI"): Same Store NOI is calculated as the Property NOI attributable to the properties owned or placed in service during the entire span of the current and prior year reporting periods. Same Store NOI excludes amounts attributable to unconsolidated joint venture assets. We present this measure on an accrual basis and a cash basis, which eliminates the effects of straight lined rents and fair value lease revenue. We believe Same Store NOI is an important measure of comparison of our properties' operating performance from one period to another. Other REITs may calculate Same Store NOI differently and our calculation should not be compared to that of other REITs.

Financial Highlights

As of March 31, 2013

Financial Results ⁽¹⁾ 

Funds from operations (FFO) for the quarter ended March 31, 2013 was $60.2 million, or $0.36 per share (diluted), compared to $60.0 million, or $0.35 per share (diluted), for the same quarter in 2012. The increase in FFO for the three months ended March 31, 2013 as compared to the same period in 2012 was principally related to the following factors: 1) increased operating income attributable to increased average occupancy for the same store properties during the first quarter of 2013 as compared to the first quarter of 2012, 2) operating income contributions from newly acquired properties, and 3) a $0.7 million reduction in general and administrative expenses during the first quarter of 2013 as compared to that of the first quarter of 2012 primarily attributable to lower legal fees, offset by 4) reduced operating income contributions attributable to sold properties in the first quarter of 2013 as compared to the first quarter of 2012, and 5) $1.2 million of acquisition costs in 2013 due to the purchase of two properties during the first quarter of 2013.

Core funds from operations (Core FFO) for the quarter ended March 31, 2013 was $61.6 million, or $0.37 per share (diluted), compared to $60.0 million, or $0.35 per share (diluted), for the same quarter in 2012. The increase in Core FFO for the three months ended March 31, 2013 as compared to the same period in 2012 was principally related to the items described above for changes in FFO, with the exception of the $1.2 million of acquisition costs associated with properties acquired during the first quarter of 2013, which were added back to Core FFO since they are expenses associated with specific capital transactions and considered to be non-recurring.

Adjusted funds from operations (AFFO) for the quarter ended March 31, 2013 was $36.6 million, or $0.22 per share (diluted), compared to $50.1 million, or $0.29 per share (diluted), for the same quarter in 2012. The decrease in AFFO for the three months ended March 31, 2013 as compared to the same period in 2012 was primarily related to the items described above for changes in FFO, as well as increased non-incremental capital expenditures of $11.9 million and increased straight line rent adjustments of $2.5 million in 2013, both of which were attributable to the high volume of recent leasing activity.

Operations

On October 29, 2012, Hurricane Sandy made landfall in the metropolitan New York City area. As previously disclosed, most of the Company's properties in the New York area were only minimally damaged from the high winds and rain. Substantially all repair work related to the storm is complete, except for some equipment replacement at 60 Broad Street, which is anticipated to be completed during the second quarter of 2013. Expenses incurred in relation to the damage caused by the storm, as well as insurance reimbursements, have been presented on Piedmont's income statement in a separate line entitled Net Casualty Gain / (Loss). Due to the non-recurring nature of Hurricane Sandy-related expenses and insurance reimbursements, such items are excluded from the calculation of Core FFO and AFFO.

On a square footage leased basis, our total office portfolio was 86.0% leased as of March 31, 2013, as compared to 84.4% as of March 31, 2012 and 87.5% as of December 31, 2012. During the twelve-month period ending March 31, 2013, our same store stabilized leased percentage increased from 87.7% at March 31, 2012 to 88.5% at March 31, 2013. The same store stabilized leased percentage excludes the impact of acquisitions and dispositions completed during the last year, as well as value-add properties (see page 37). The primary reason for the increase in the leased percentage for our same store stabilized assets during that period is positive net absorption attributable to several recent large lease transactions for previously vacant spaces, most notably the 301,000 square foot Catamaran lease at Windy Point II in Schaumburg, IL and the 102,000 square foot Brother International lease at 200 Bridgewater Crossing in Bridgewater, NJ. Please refer to page 26 for additional leased percentage information.

The weighted average remaining lease term of our portfolio was 7.1 years⁽²⁾ as of March 31, 2013 as compared to 6.9 years at December 31, 2012.

During the three months ended March 31, 2013, the Company completed 487,000 square feet of total leasing. Of the total leasing activity during the quarter, we signed renewal leases for 367,000 square feet and new tenant leases for 120,000 square feet. During the first quarter of 2013, we completed 479,000 square feet of leasing for our consolidated office properties. The average committed capital cost for all leases signed during the quarter at our consolidated office properties was $2.91 per square foot per year of lease term. Average committed capital cost per square foot per year of lease term for renewal leases signed during the three months ended March 31, 2013 was $2.38 and average committed capital cost per square foot per year of lease term for new leases signed during the same time period was $5.43 (see page 32).

(1)	FFO, Core FFO and AFFO are supplemental non-GAAP financial measures. See page 39 for definitions of non-GAAP financial measures. See pages 14 and 41 for reconciliations of FFO, Core FFO and AFFO to Net Income.
(2)	Remaining lease term (after taking into account leases for vacant spaces which had been executed but not commenced as of March 31, 2013) is weighted based on Annualized Lease Revenue, as defined on page 39.

During the three months ended March 31, 2013, we executed four leases greater than 20,000 square feet at our consolidated office properties. Please see information on those leases listed below.

Tenant	Property	Property Location	Square Feet Leased	Expiration Year	Lease Type

Leasing Update

As of March 31, 2013, there were four tenants whose leases were in holdover or were scheduled to expire during the eighteen month period following the end of the first quarter of 2013 and contributed greater than 1% in net Annualized Lease Revenue (ALR) expiring during that period. Information regarding the leasing status of the spaces associated with those tenants' leases is presented below.

Tenant	Property	Property Location	Net Square Footage Expiring	Net Percentage of Current Quarter Annualized Lease Revenue Expiring(%)	Expiration (1)	Current Leasing Status
United States of America (National Park Service)	1201 Eye Street	Washington, D.C.	219,750	1.8%	Holdover	National Park Service is now in holdover status. The Company is in discussions with the National Park Service for a lease renewal.
BP	Aon Center	Chicago, IL	97,965	1.7%	Q4 2013	Approximately 91% of the square footage leased by BP has been leased on a long-term basis to: Aon Corporation, Thoughtworks, Integrys Energy Group, and Federal Home Loan Bank. Three of these future tenants are current subtenants. The remaining available space is actively being marketed for lease.
United States of America (Defense Intelligence Agency)	3100 Clarendon Boulevard	Arlington, VA	221,084	1.6%	Q4 2013	In December 2012, the Defense Intelligence Agency exercised a termination option pursuant to its lease. The lease will now expire December 31, 2013. The Company is actively marketing the space for lease.

Occupancy versus NOI Analysis

Piedmont has been in a period of high lease rollover since 2010. This high lease rollover has resulted in a decrease in leased percentage and economic leased percentage over the past three years. This, in turn, has effected a lower Same Store NOI than might otherwise be anticipated given the overall leased percentage and the historical relationship between leased percentage and Same Store NOI. As of March 31, 2013, our overall leased percentage was 86.0% and our economic leased percentage was 76.4%. The difference between overall leased percentage and economic leased percentage is attributable to two factors:

1. leases which have been contractually entered into for currently vacant space which have not commenced (amounting to approximately 384,000 square feet of leases as of March 31, 2013, or 1.8% of the office portfolio); and

2. leases which have commenced but the tenants have not commenced paying full rent due to rental abatements (amounting to 2.0 million square feet of leases as of March 31, 2013, or a 7.8% impact to leased percentage on an economic basis). Please see the chart below for a listing of major contributors.

As the executed but not commenced leases begin and the rental abatement periods expire, there will be greater Same Store NOI growth than might otherwise be expected based on changes in overall leased percentage alone during that time period.

7

Due to the current economic environment, many new leases provide for rental abatement concessions to tenants. Those rental abatements typically occur at the beginning of a new lease's term. Since 2010, Piedmont has signed approximately 9.4 million square feet of leases within its consolidated office portfolio. Due to the large number of new leases in the Company's portfolio, abatements provided under those new leases have impacted the Company's current cash net operating income and AFFO. Presented below is a schedule of leases greater than 50,000 square feet that are currently under some form of rent abatement.

Financing and Capital Activity

As of March 31, 2013, our ratio of debt to total gross assets was 30.8%, our ratio of debt to gross real estate assets was 35.2%, and our ratio of debt to total market capitalization was 34.1%. These debt ratios are based on total principal amount outstanding for our various loans at March 31, 2013.

On March 4, 2013, Piedmont completed the purchase of Arlington Gateway, a twelve-story office building comprised of approximately 334,000 square feet in Arlington, VA. The purchase price was approximately $175.6 million, or $526 per square foot. The construction of the 99% leased building was completed in 2005. The property is both LEED certified and Energy Star rated. The building benefits from a rich amenity base, including close proximity to Metro. The acquisition allowed the Company to increase its concentration in the Rosslyn-Ballston Corridor submarket of Washington, D.C., as well as further its strategic objective of increasing ownership in its identified concentration markets.

On March 22, 2013, Piedmont completed the purchase of 5 & 15 Wayside Road, a multi-story project comprised of 271,000 square feet of office space in Burlington, MA. The purchase price was approximately $69.3 million, or $255 per square foot. The 95% leased, two-building project was constructed in 1999 and 2001. Well-located along Route 128 / Interstate 95, the project is easily accessed by commuters and affords tenants quick access to the area's deep retail amenity base. The acquisition allowed the Company to further its strategic objective of increasing ownership in its identified concentration markets.

On March 28, 2013, Piedmont completed the sale of 1111 Durham Avenue, a 237,000 square foot office building located in South Plainfield, NJ. The property, built in 1975, was sold for $4.0 million. Piedmont recorded an impairment loss on the asset of approximately $6.4 million when it was reclassified to held for sale. The subsequent sale allowed the Company to divest an outdated, non-core property, consistent with its long-term strategic objectives for location and building quality. The operating income for the asset is presented in discontinued operations.

On March 22, 2013, Piedmont entered into a binding contract to sell 1200 Enclave Parkway, a 150,000 square foot office building located in Houston, TX for $48.75 million, or $326 per square foot. The transaction closed on May 1, 2013. Piedmont will record a gain on the sale of the building during the second quarter of 2013. The Company purchased the property in March 2011 for $18.5 million under its value-add strategy. At the time, the property was 18% leased; the building is now 100% leased. The Company intends to deploy the value it created through the re-leasing of the property to full occupancy into other assets. During the first quarter of 2013, the property was reclassified from real estate assets held-for-use to real estate assets held-for-sale; the operating income for the asset is presented in discontinued operations.

8

In 2014, three of the Company's secured debt instruments will mature. The Company currently intends to issue unsecured bonds to repay most to all of the maturing debt. In anticipation of issuing unsecured bonds and considering the historically low interest rate environment, Piedmont has entered into a forward starting swap hedging program to partially protect the Company against rising interest rates and to lock a portion of the interest rate of the future bond issuance. Specifically, under this hedging program and through the hedge instruments, the Company will be effectively locking the treasury component of the all-in interest rate for its future ten-year tenored unsecured bond offering. As of the end of the first quarter, the Company had entered into two forward starting swaps with a blended rate of 2.23% and a notional amount of $140 million. Subsequent to quarter end, the Company has entered into two additional forward starting swaps, resulting in a notional amount of $280 million hedged under the program at a blended rate of 2.19%. At current swap spread levels, the Company effectively locked the treasury component for a 2014 bond issuance at approximately 2.02%. The Company may enter into additional forward starting swaps in advance of $575 million of secured debt maturing in early 2014.

On February 27, 2013, the Board of Directors of Piedmont declared dividends for the first quarter of 2013 in the amount of $0.20 per common share outstanding to stockholders of record as of the close of business on March 11, 2013. The dividends were paid on March 22, 2013. The Company's dividend payout percentage for the three months ended March 31, 2013 was 54.4% of Core FFO and 91.6% of AFFO.

During the first quarter of 2013, the Company repurchased 600 shares of common stock under its share repurchase program. Since the stock repurchase program began in December 2011, the Company has repurchased a total of 5.5 million shares at an average price of $16.83 per share, or approximately $91.8 million in aggregate (before consideration of transaction costs). As of quarter end, Board-approved capacity remaining for additional repurchases totaled approximately $208 million under the stock repurchase plan.

Since 2007, the Company has been a defendant in two class action lawsuits alleging inadequate disclosures in 2007 in SEC filings related to its internalization, response to a tender offer, and amendments to the Company's charter. As previously disclosed, the Company reached tentative settlements with the plaintiffs in both cases totaling $7.5 million. During the first quarter of 2013, the court preliminarily approved the proposed settlements. The settlements were granted final approval by the court on April 18, 2013. The settlements are within available insurance limits and the Company is seeking recovery of these settlements from its insurance carriers. Please see Piedmont's Form 10-Q dated as of March 31, 2013 and its latest Form 10-K for further disclosure.

Subsequent Events

On May 2, 2013, the Board of Directors of Piedmont declared dividends for the second quarter of 2013 in the amount of $0.20 per common share outstanding to stockholders of record as of the close of business on May 31, 2013. The dividends are to be paid on June 21, 2013.

Guidance for 2013

The following financial guidance for calendar year 2013 remains unchanged and is based upon management's expectations at this time:

	Low	High
Core Funds from Operations	$225 million	$243 million
Core Funds from Operations per diluted share	$1.35	$1.45

These estimates reflect management’s view of current market conditions and incorporate certain economic and operational assumptions and projections. Actual results could differ from these estimates. Note that individual quarters may fluctuate on both a cash and an accrual basis due to the timing of lease commencements and expirations, repairs and maintenance, capital expenditures, capital markets activities and one-time revenue or expense events. In addition, the Company’s guidance is based on information available to management as of the date of this supplemental report.

(1)	Please refer to page 26 for additional leased percentage information.
(2)	Please refer to page 37 for additional information on value-add properties, data for which is removed from stabilized portfolio totals.
(3)	Net debt is calculated as the total principal amount of debt outstanding minus cash and cash equivalents and escrow deposits and restricted cash. The increase in net debt is primarily attributable to capital expenditures and stock repurchases completed in 2012, as well as the acquisition of two properties during the first quarter of 2013.
(4)	Core EBITDA margin is calculated as Core EBITDA divided by total revenues (including revenues associated with discontinued operations).
(5)	The fixed charge coverage ratio is calculated as Core EBITDA divided by the sum of interest expense, principal amortization, capitalized interest and preferred dividends. The Company had no capitalized interest, principal amortization or preferred dividends during any of the periods presented.
(6)	Core EBITDA is annualized for the purposes of this calculation. During the first quarter of 2013, we acquired two properties in the last month of the quarter; the borrowings to complete the acquisitions are reflected in the numerator and full quarter contributions to EBITDA by the properties acquired have been included on a pro forma basis in the denominator as if the properties had been owned as of the beginning of the quarter. If the actual, partial quarter EBITDA contributions by the properties acquired were to be reflected, the net debt to Core EBITDA ratio would be 5.4 x.

(4)	The decrease in Washington, D.C. Same Store Net Operating Income for the three months ended March 31, 2013 as compared to the same period in 2012 was primarily attributable to the expiration of the Office of the Comptroller of the Currency lease at One Independence Square in Washington D.C., offset somewhat by increased rental revenue as a result of the expirations of the rental abatement periods for several leases at Piedmont Pointe I & II in Bethesda, MD.
(5)	The decrease in Chicago Same Store Net Operating Income for the three months ended March 31, 2013 as compared to the same period in 2012 was primarily related to gross rental abatements associated with several new leases, most notably that of GE Capital, at 500 West Monroe Street in Chicago, IL, as well as a prior year operating expense recovery true-up with a former tenant that occurred in 2012 and did not recur in 2013 at Windy Point II in Schaumburg, IL.
(6)	The percentage contribution from Chicago to our total Same Store Net Operating Income is smaller than our geographic concentration percentage in Chicago, which is presented on an ALR basis (see page 33), primarily because of the large number of leases with gross rent abatements and a number of leases yet to commence for currently vacant space (the projected gross rent for which is included in our ALR calculation). As the gross rent abatements burn off and as executed but not commenced leases begin, the Same Store Net Operating Income percentage contribution from Chicago should increase and should be more closely aligned with our Chicago concentration percentage as presented on page 33.
(7)	The increase in Minneapolis Same Store Net Operating Income for the three months ended March 31, 2013 as compared to the same period in 2012 was primarily related to the expirations of the rental abatement periods associated with several new leases at US Bancorp Center in Minneapolis, MN and Crescent Ridge II in Minnetonka, MN.
(8)	The increase in Boston Same Store Net Operating Income for the three months ended March 31, 2013 as compared to the same period in 2012 was primarily related to the expiration of the rental abatement period for the State Street Bank lease at 1200 Crown Colony Drive in Quincy, MA, as well as a property tax recovery true-up that occurred in 2013 at One Brattle Square in Cambridge, MA.
(9)	The increase in Other Same Store Net Operating Income for the three months ended March 31, 2013 as compared to the same period in 2012 was primarily related to the expirations of rental abatement periods associated with new leases with Grand Canyon Education at Desert Canyon 300 in Phoenix, AZ and Chrysler Group, LLC at 1075 West Entrance Drive in Auburn Hills, MI.

(4)	The decrease in Washington, D.C. Same Store Net Operating Income for the three months ended March 31, 2013 as compared to the same period in 2012 was primarily attributable to the expiration of the Office of the Comptroller of the Currency lease at One Independence Square in Washington D.C., as well as a prior year property tax recovery true-up that occurred in 2012 and did not recur in 2013 at Two Independence Square in Washington, D.C. The decrease in Washington, D.C. Same Store Net Operating Income for the three months ended March 31, 2013 as compared to the same period in 2012 was offset somewhat by increased rental revenue as a result of the commencement of several new leases at Piedmont Pointe II in Bethesda, MD.
(5)	The increase in New York Same Store Net Operating Income for the three months ended March 31, 2013 as compared to the same period in 2012 was primarily related to one-time expense recovery adjustments at 60 Broad Street in New York, NY which are not expected to recur.
(6)	The increase in Chicago Same Store Net Operating Income for the three months ended March 31, 2013 as compared to the same period in 2012 was primarily related to an increase in rental revenue at Aon Center in Chicago, IL due to the commencement of a 239,000 square foot lease with KPMG and a 55,000 square foot lease with United HealthCare in the second half of 2012.
(7)	The percentage contribution from Chicago to our total Same Store Net Operating Income is smaller than our geographic concentration percentage in Chicago, which is presented on an ALR basis (see page 33), primarily because of the large number of leases with operating expense recovery abatements (which abatements are not included in straight line rent adjustments) and a number of leases yet to commence for currently vacant space (the projected gross rent for which is included in our ALR calculation). As operating expense recovery abatements burn off and as executed but not commenced leases begin, the Same Store Net Operating Income percentage contribution from Chicago should increase and should be more closely aligned with our Chicago concentration percentage as presented on page 33.
(8)	The increase in Minneapolis Same Store Net Operating Income for the three months ended March 31, 2013 as compared to the same period in 2012 was primarily related to the early renewal of the US Bancorp lease as well as the expiration of the operating expense recovery abatement periods associated with several new leases at US Bancorp Center in Minneapolis, MN.

(1)	All of Piedmont's outstanding debt as of March 31, 2013 was interest-only debt.
(2)	Amount represents the outstanding balance as of March 31, 2013, on the $500 million unsecured revolving credit facility. The $300 million unsecured term loan has a stated variable rate; however, Piedmont entered into interest rate swap agreements which effectively fix the interest rate on this loan at 2.69% through its maturity date of November 22, 2016, assuming no credit rating change for the Company. This unsecured term loan, therefore, is reflected as fixed rate debt.
(3)	The weighted average interest rate is a weighted average rate for amounts outstanding under our $500 million unsecured revolving credit facility and our $300 million unsecured term loan.
(4)	The initial maturity date of the $500 million unsecured revolving credit facility is August 19, 2016; however, there are two, six-month extension options available under the facility providing for a final extended maturity date of August 21, 2017. For the purposes of this schedule, we reflect the maturity date of the facility as the final extended maturity date of August 2017.

Fixed charge coverage ratio (5)	4.8 x	4.7 x
Interest coverage ratio (6)	4.8 x	4.7 x

(1)	Debt covenant compliance calculations relate to specific calculations detailed in our credit agreements.
(2)	Defined as EBITDA for the trailing four quarters (including the Company's share of EBITDA from unconsolidated interests), less one-time or non-recurring gains or losses, less a $0.15 per square foot capital reserve, and excluding the impact of straight line rent leveling adjustments and amortization of intangibles divided by the Company's share of fixed charges, as more particularly described in the credit agreements. This definition of fixed charge coverage ratio as prescribed by our credit agreements is different from the fixed charge coverage ratio definition employed elsewhere within this report.
(3)	Defined as net operating income for the trailing four quarters for unencumbered assets (including the Company's share of net operating income from partially-owned entities and subsidiaries that are deemed to be unencumbered) less a $0.15 per square foot capital reserve divided by the Company's share of interest expense associated with unsecured financings only, as more particularly described in the credit agreements.
(4)	During the first quarter of 2013, we acquired two properties in the last month of the quarter; the borrowings to complete the acquisitions are reflected in the numerator and full quarter contributions to EBITDA by the properties acquired have been included on a pro forma basis in the denominator as if the properties had been owned as of the beginning of the quarter. If the actual, partial quarter EBITDA contributions by the properties acquired were to be reflected, the net debt to Core EBITDA ratio would be 5.4 x.
(5)	Fixed charge coverage is calculated as Core EBITDA divided by the sum of interest expense, principal amortization, capitalized interest and preferred dividends. The Company had no capitalized interest, principal amortization or preferred dividends during the periods ended March 31, 2013 and December 31, 2012.
(6)	Interest coverage ratio is calculated as Core EBITDA divided by the sum of interest expense and capitalized interest. The Company had no capitalized interest during the periods ended March 31, 2013 and December 31, 2012.

Leased Percentage Information

(in thousands)

Impact of Strategic Transactions on Leased Percentage

The Company’s stated long-term growth strategy includes the recycling of capital from certain stabilized or non-core assets into office properties located in focused concentration and opportunistic markets. Some of the recently acquired properties are value-add properties which are defined as low-occupancy properties acquired at attractive bases with earnings growth and value appreciation potential achievable through leasing up such assets to a stabilized occupancy. Because the value-add properties have large vacancies, they negatively affect Piedmont’s overall leased percentage. In order to identify the effect they have on Piedmont’s overall leased percentage, the following information is being provided. The analysis below: 1) removes the impact of the value-add properties from Piedmont’s overall office portfolio total under the heading “Stabilized Portfolio Analysis”; 2) provides a year-over-year comparison of leased percentage on the same subset of properties under the heading “Same Store Analysis”; and 3) provides a year-over-year comparison of leased percentage on the same subset of stabilized properties under the heading "Same Store Stabilized Analysis".

(2)	The square footage associated with leases with end of period expiration dates is included in the end of the period leased square footage.
(3)	End of period leased square footage for 2013 includes short-term space leased on behalf of NASA in accordance with requirements stipulated under its lease to allow it to restructure its space at Two Independence Square in Washington, D.C. As of March 31, 2013, the total short-term space amounts to approximately 63,000 square feet and it will be occupied until an estimated date of July 31, 2014.
(4)	For additional information on acquisitions and dispositions completed during the last year and value-add properties, please refer to pages 36 and 37, respectively.
(5)	Dispositions completed during the previous twelve months are deducted from the previous period data and acquisitions completed during the previous twelve months are deducted from the current period data.

(1)	The population analyzed consists of consolidated office leases executed during the period with lease terms greater than one year. Retail leases, as well as leases associated with storage spaces, management offices, and unconsolidated joint venture assets, were excluded from this analysis.
(2)	For the purposes of this analysis, the cash rents last in effect for the previous leases were compared to the initial cash rents of the new leases in order to calculate the percentage change.
(3)	For the purposes of this analysis, the accrual basis rents for the previous leases were compared to the accrual basis rents of the new leases in order to calculate the percentage change. For newly signed leases which have variations in accrual basis rents, whether because of known future expansions, contractions, lease expense recovery structure changes, or other similar reasons, the weighted average of such accrual basis rents is used for the purposes of this analysis.
(4)	For leases under which a tenant may use, at its discretion, a portion of its tenant improvement allowance for expenses other than those related to improvements to its space, an assumption is made that the tenant elects to use any such portion of its tenant improvement allowance for improvements to its space prior to the commencement of its lease, unless the Company is notified otherwise by the tenant. This assumption is made based upon the historical tenant improvement allowance usage patterns of the Company's tenants.
(5)	Each of the three largest lease renewals were lease restructurings, which rolled down rents but also had lower associated capital expenditure requirements. The net effect of these transactions was a low capital commitment per square foot per year of lease term for the quarter, offset by a larger decrease in rents. The three largest lease renewals were: the FedEx Corporate Services lease at 350 Spectrum Loop in Colorado Springs, CO, the Lockheed Martin lease at 400 Virginia Avenue in Washington, D.C., and the Miller Canfield lease at 150 West Jefferson Avenue in Detroit, MI.
(6)	Represents leases signed at our consolidated office assets that do not qualify for inclusion in the analysis primarily because the spaces for which the new leases were signed had been vacant for greater than one year.

Annualized rental income associated with newly executed leases for currently occupied space is incorporated herein only at the expiration date for the current lease. Annualized rental income associated with such new leases is removed from the expiry year of the current lease and added to the expiry year of the new lease. These adjustments effectively incorporate known roll ups and roll downs into the expiration schedule.

(2)

Leases and other revenue-producing agreements on a month-to-month basis, aggregating 8,327 square feet and Annualized Lease Revenue of $330,861, are assigned a lease expiration date of a year and a day beyond the period end date. Includes leases with an expiration date of March 31, 2013 aggregating 21,115 square feet and Annualized Lease Revenue of $705,996, as well as the National Park Service lease, which is comprised of 219,750 square feet and $10.0 million in Annualized Lease Revenue, or 1.8% of the Company's total Annualized Lease Revenue.

NOTE: This information is presented for our consolidated office assets only and excludes activity associated with storage spaces.

(1)	For leases under which a tenant may use, at its discretion, a portion of its tenant improvement allowance for expenses other than those related to improvements to its space, an assumption is made that the tenant elects to use any such portion of its tenant improvement allowance for improvements to its space prior to the commencement of its lease, unless the Company is notified otherwise by the tenant. This assumption is made based upon the historical tenant improvement allowance usage patterns of the Company's tenants.
(2)	During 2011, we completed two large, 15-year lease renewals with significant capital commitments: NASA at Two Independence Square in Washington, D.C. and GE at 500 West Monroe Street in Chicago, IL. If the costs associated with these renewals were to be removed from the average committed capital cost calculation, the average committed capital cost per square foot per year of lease term for renewal leases in 2011 would be $2.80. During 2012, we completed one large, long-term lease renewal with an above-average capital commitment with US Bancorp at US Bancorp Center in Minneapolis, MN. If the costs associated with this renewal were to be removed from the average committed capital cost calculation, the average committed capital cost per square foot per year of lease term for renewal leases in 2012 would be $2.73.
(3)	Since 2010, Piedmont has selectively employed a value-add strategy for new property acquisitions. Piedmont defines value-add properties as those acquired with low occupancies at attractive bases with earnings growth and value appreciation potential achievable through leasing up such assets to stabilized occupancies. Because the value-add properties have large vacancies, many of which have not previously been leased (first generation spaces), the leasing of those vacancies negatively affects Piedmont’s contractual tenant improvements on a per foot and a per foot per year basis for new leases.

(1)	The property consists of approximately 334,000 square feet; however, due to the square footages referenced in several leases, the rentable square footage is currently 323,000 square feet. As the existing leases expire, the affected spaces will be re-leased to the correct square footages.
(2)	Sale price and rentable square footage are gross figures and have not been adjusted for Piedmont's ownership percentage.
(3)	Piedmont exercised a landlord termination option for one full floor immediately prior to the sale of the property to Nike, Inc. After the effectiveness of the termination, the leased percentage became 50%.

Supplemental Definitions

Included in this section are management's statements regarding certain non-GAAP financial measures provided in this supplemental report and reasons why management believes that these measures provide useful information to investors about the Company's financial condition and results of operations. Reconciliations of these non-GAAP measures are included beginning on page 41.

Adjusted Funds From Operations ("AFFO"): AFFO is calculated by deducting from Core FFO non-incremental capital expenditures and acquisition-related costs and adding back non-cash items including non-real estate depreciation, straight lined rents and fair value lease revenue, non-cash components of interest expense and compensation expense, and by making similar adjustments for unconsolidated partnerships and joint ventures. Although AFFO may not be comparable to that of other REITs, we believe it provides a meaningful indicator of our ability to fund cash needs and to make cash distributions to equity owners. AFFO is a non-GAAP financial measure and should not be viewed as an alternative measurement of our operating performance to net income, as an alternative to net cash flows from operating activities or as a measure of our liquidity.

Annualized Lease Revenue ("ALR"): ALR is calculated by multiplying (i) rental payments (defined as base rent plus operating expense reimbursements, if payable by the tenant on a monthly basis under the terms of a lease that has been executed, but excluding a) rental abatements and b) rental payments related to executed but not commenced leases for space that was covered by an existing lease), by (ii) 12. In instances in which contractual rents or operating expense reimbursements are collected on an annual, semi-annual, or quarterly basis, such amounts are multiplied by a factor of 1, 2, or 4, respectively, to calculate the annualized figure. For leases that have been executed but not commenced relating to un-leased space, ALR is calculated by multiplying (i) the monthly base rental payment (excluding abatements) plus any operating expense reimbursements for the initial month of the lease term, by (ii) 12. Unless stated otherwise, this measure excludes our unconsolidated joint venture interests.

Core EBITDA: Core EBITDA is defined as net income before interest, taxes, depreciation and amortization and incrementally removing any impairment losses, gains or losses from sales of property, or other significant non-recurring items. We do not include impairment losses in this measure because we feel these types of losses create volatility in our earnings and make it difficult to determine the earnings generated by our ongoing business. We believe Core EBITDA is a reasonable measure of our liquidity. Core EBITDA is a non-GAAP financial measure and should not be viewed as an alternative measurement of cash flows from operating activities or other GAAP basis liquidity measures. Other REITs may calculate Core EBITDA differently and our calculation should not be compared to that of other REITs.

Core Funds From Operations ("Core FFO"): We calculate Core FFO by starting with FFO, as defined by NAREIT, and adjusting for certain non-recurring items such as gains or losses on the early extinguishment of debt, acquisition-related costs and other significant non-recurring items. Such items create significant earnings volatility. We believe Core FFO provides a meaningful measure of our operating performance and more predictability regarding future earnings potential. Core FFO is a non-GAAP financial measure and should not be viewed as an alternative measurement of our operating performance to net income; therefore, it should not be compared to other REITs' equivalent to Core FFO.

EBITDA: EBITDA is defined as net income before interest, taxes, depreciation and amortization. We believe EBITDA is an appropriate measure of our ability to incur and service debt. EBITDA should not be considered as an alternative to cash flows from operating activities, as a measure of our liquidity or as an alternative to net income as an indicator of our operating activities. Other REITs may calculate EBITDA differently and our calculation should not be compared to that of other REITs.

Funds From Operations ("FFO"): FFO is calculated in accordance with the current National Association of Real Estate Investment Trusts ("NAREIT") definition. NAREIT currently defines FFO as net income (computed in accordance with GAAP), excluding gains or losses from sales of property and impairment losses, adding back depreciation and amortization on real estate assets, and after the same adjustments for unconsolidated partnerships and joint ventures. These adjustments can vary among owners of identical assets in similar conditions based on historical cost accounting and useful-life estimates. FFO may provide valuable comparisons of operating performance between periods and with other REITs. FFO is a non-GAAP financial measure and should not be viewed as an alternative measurement of our operating performance to net income. We believe that FFO is a beneficial indicator of the performance of an equity REIT. However, other REITs may not define FFO in accordance with the NAREIT definition, or may interpret the current NAREIT definition differently than we do; therefore, our computation of FFO may not be comparable to that of such other REITs.

Gross Assets: Gross assets is defined as total assets with the add back of accumulated depreciation and accumulated amortization related to real estate assets.

Gross Real Estate Assets: Gross real estate assets is defined as total real estate assets with the add back of accumulated depreciation and accumulated amortization related to real estate assets.

Incremental Capital Expenditures: Incremental Capital Expenditures are defined as capital expenditures of a non-recurring nature that incrementally enhance the underlying assets' income generating capacity. Tenant improvements, leasing commissions, building capital and deferred lease incentives ("Leasing Costs") incurred to lease space that was vacant at acquisition, Leasing Costs for spaces vacant for greater than one year, Leasing Costs for spaces at newly acquired properties for which in-place leases expire shortly after acquisition, improvements associated with the expansion of a building and renovations that change the underlying classification of a building are included in this measure.

NOI from Unconsolidated Joint Ventures: NOI from Unconsolidated Joint Ventures is defined as Property NOI attributable to our interests in properties owned through unconsolidated partnerships. We present this measure on an accrual basis and a cash basis, which eliminates the effects of straight lined rents and fair value lease revenue. NOI from Unconsolidated Joint Ventures is a non-GAAP measure and therefore may not be comparable to similarly defined data provided by other REITs.

Non-Incremental Capital Expenditures: Non-Incremental Capital Expenditures are defined as capital expenditures of a recurring nature related to tenant improvements and leasing commissions that do not incrementally enhance the underlying assets' income generating capacity. We exclude first generation tenant improvements and leasing commissions from this measure, in addition to other capital expenditures that qualify as Incremental Capital Expenditures, as defined above.

Property Net Operating Income ("Property NOI"): Property NOI is defined as real estate operating income with the add-back of corporate general and administrative expense, depreciation and amortization, and impairment losses and the deduction of income and expense associated with lease terminations and income associated with property management performed by Piedmont for other organizations. We present this measure on an accrual basis and a cash basis, which eliminates the effects of straight lined rents and fair value lease revenue. The Company uses this measure to assess its operating results and believes it is important in assessing operating performance. Property NOI is a non-GAAP measure which does not have any standard meaning prescribed by GAAP and therefore may not be comparable to similar measures presented by other companies.

Same Store Net Operating Income ("Same Store NOI"): Same Store NOI is calculated as the Property NOI attributable to the properties owned or placed in service during the entire span of the current and prior year reporting periods. Same Store NOI excludes amounts attributable to unconsolidated joint venture assets. We present this measure on an accrual basis and a cash basis, which eliminates the effects of straight lined rents and fair value lease revenue. We believe Same Store NOI is an important measure of comparison of our properties' operating performance from one period to another. Other REITs may calculate Same Store NOI differently and our calculation should not be compared to that of other REITs.

Same Store Properties: Same Store Properties is defined as properties owned or placed in service during the entire span of the current and prior year reporting periods. Same Store Properties excludes unconsolidated joint venture assets. We believe Same Store Properties is an important measure of comparison of our stabilized portfolio performance.

(1)	Economic leased percentage excludes the square footage associated with executed but not commenced leases for currently vacant spaces and the square footage associated with tenants receiving rental abatements (after proportional adjustments for tenants receiving only partial rent abatements).
(2)	Although Piedmont owns 49.5% of the asset, it is entitled to 100% of the cash flows under the terms of the property ownership entity's joint venture agreement.
(3)	The property consists of approximately 334,000 square feet; however, due to the square footages referenced in several leases, the rentable square footage is currently 323,000 square feet. As the existing leases expire, the affected spaces will be re-leased to the correct square footages.

Risks, Uncertainties and Limitations

Certain statements contained in this supplemental package constitute forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”) and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). We intend for all such forward-looking statements to be covered by the safe-harbor provisions for forward-looking statements contained in Section 27A of the Securities Act and Section 21E of the Exchange Act, as applicable. Such information is subject to certain risks and uncertainties, as well as known and unknown risks, which could cause actual results to differ materially from those projected or anticipated. Therefore, such statements are not intended to be a guarantee of our performance in future periods. Such forward-looking statements can generally be identified by our use of forward-looking terminology such as “may,” “will,” “expect,” “intend,” “anticipate,” “believe,” “continue” or similar words or phrases that are predictions of future events or trends and which do not relate solely to historical matters.

The following are some of the factors that could cause our actual results and expectations to differ materially from those described in our forward-looking statements: market and economic conditions remain challenging and the demand for office space, rental rates and property values may continue to lag the general economic recovery causing our business, results of operations, cash flows, financial condition and access to capital to be adversely affected or otherwise impact performance, including the potential recognition of impairment charges; the success of our real estate strategies and investment objectives, including our ability to identify and consummate suitable acquisitions; lease terminations or lease defaults, particularly by one of our large lead tenants; the impact of competition on our efforts to renew existing leases or re-let space on terms similar to existing leases; changes in the economies and other conditions of the office market in general and of the specific markets in which we operate, particularly in Chicago, Washington, D.C., and the New York metropolitan area; economic and regulatory changes, including accounting standards, that impact the real estate market generally; additional risks and costs associated with directly managing properties occupied by government tenants; adverse market and economic conditions may continue to adversely affect us and could cause us to recognize impairment charges or otherwise impact our performance; availability of financing and our lending banks' ability to honor existing line of credit commitments; costs of complying with governmental laws and regulations; uncertainties associated with environmental and other regulatory matters; potential changes in political environment and reduction in federal and/or state funding of our governmental tenants; we may be subject to litigation, which could have a material adverse effect on our financial condition; our ability to continue to qualify as a real estate investment trust under the Internal Revenue Code; and other factors detailed in our most recent Annual Report on Form 10-K and other documents we file with the Securities and Exchange Commission.

Readers are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date of this supplemental report. We cannot guarantee the accuracy of any such forward-looking statements contained in this supplemental report, and we do not intend to publicly update or revise any forward-looking statements, whether as a result of new information, future events, or otherwise.
