Corporate Data

Piedmont Office Realty Trust, Inc. (“Piedmont” or the “Company”) (NYSE: PDM) is a fully-integrated and self-managed real estate investment trust (“REIT”) specializing in the acquisition, ownership, management, development and disposition of primarily high-quality Class A office buildings located predominantly in large U.S. office markets and leased principally to high-credit-quality tenants. Approximately 82% of our Annualized Lease Revenue (“ALR”)⁽¹⁾ is derived from our office properties located within the ten largest U.S. office markets, including Chicago, Washington, D.C., the New York metropolitan area, Boston and greater Los Angeles. Since its first acquisition in 1998, the Company has acquired $5.9 billion of office and industrial properties (inclusive of joint ventures) through December 31, 2011. Rated as an investment-grade company by Standard & Poor’s and Moody’s, Piedmont has maintained a low-leverage strategy while acquiring its properties.

This data supplements the information provided in our reports filed with the Securities and Exchange Commission and should be reviewed in conjunction with such filings.

⁽²⁾ As of December 31, 2011, our office portfolio consisted of 79 properties (exclusive of our equity interests in five properties owned through unconsolidated joint ventures and our two industrial properties). During the fourth quarter of 2011, we sold our ownership interest in 35 West Wacker Drive, a 1,118,000 square foot property located in Chicago, IL, and we purchased 400 TownPark, a 176,000 square foot property located in Lake Mary, FL. For additional detail on asset transactions during 2011, please refer to page 32.

⁽³⁾  Calculated as leased square footage on December 31, 2011 plus square footage associated with executed new leases for currently vacant spaces divided by total rentable square footage, expressed as a percentage. This measure is presented for our 79 office properties and excludes industrial and unconsolidated joint venture properties. Please refer to page 23 for additional analyses regarding Piedmont’s leased percentage.

⁽⁴⁾  Please refer to page 33 for information regarding value-add properties, data for which is removed from stabilized portfolio totals.

⁽⁶⁾  Weighted average fully diluted shares outstanding are presented on a year-to-date basis for each period.

⁽⁷⁾  During 2011, the company hired a regional manager and additional staff for its New York, NY office. The opening of this office is the primary reason for the increase in number of employees.

Financial Highlights

As of December 31, 2011

On January 22, 2010, we filed an amendment to our charter to effect a recapitalization of our common stock as described further in our Securities and Exchange Commission (“SEC”) filings. The recapitalization had the effect of a one-for-three reverse stock split. All prior period per share data has been restated to give net effect to this one-for-three reverse stock split.

Financial Results⁽¹⁾                    

-  Funds from operations (FFO) for the quarter ended December 31, 2011 was $65.9 million, or $0.38 per share (diluted), compared to $67.9 million, or $0.39 per share (diluted), for the same quarter in 2010. FFO for the twelve months ended December 31, 2011 was $271.3 million, or $1.57 per share (diluted), compared to $281.3 million, or $1.65 per share (diluted), for the same period in 2010. The decrease in FFO for the three months ended December 31, 2011 as compared to the same period in 2010 was principally related to lower termination income in the fourth quarter of 2011 and reduced tenant reimbursements due to a decrease in year-over-year leased percentage; these items were partially offset by increased rental income contributed from properties acquired during the last year and reduced general and administrative costs attributable to lower transfer agent expenses. The decrease in FFO for the twelve months ended December 31, 2011 as compared to the same period in 2010 was principally related to increased property operating costs associated with newly acquired properties and reduced termination fee income in 2011; these items were partially offset by the same transfer agent expense savings mentioned above.

-  Core funds from operations (Core FFO) for the quarter ended December 31, 2011 was $65.3 million, or $0.38 per share (diluted), compared to $68.2 million, or $0.39 per share (diluted), for the same quarter in 2010. Core FFO for the twelve months ended December 31, 2011 was $271.6 million, or $1.57 per share (diluted), compared to $281.9 million, or $1.65 per share (diluted), for the same period in 2010. The decrease in Core FFO for the three and the twelve months ended December 31, 2011 as compared to the same periods in 2010 was principally related to the items described for changes in FFO above. Incremental differences relate to the add back of acquisition-related expenses and the deduction of the gain on early extinguishment of debt associated with the discounted payoff of a portion of the debt related to 500 West Monroe Street in 2011.

-  Adjusted funds from operations (AFFO) for the quarter ended December 31, 2011 was $44.7 million, or $0.26 per share (diluted), compared to $42.0 million, or $0.24 per share (diluted), for the same quarter in 2010. AFFO for the twelve months ended December 31, 2011 was $202.6 million, or $1.17 per share (diluted), compared to $228.7 million, or $1.34 per share (diluted), for the same period in 2010. The increase in AFFO for the three months ended December 31, 2011 as compared to the same period in 2010 was primarily related to a decrease in non-incremental capital expenditures, offset somewhat by the items described for the negative FFO variance above. The decrease in AFFO for the twelve months ended December 31, 2011 as compared to the same period in 2010 was primarily due to increased capital expenditures in 2011 associated with increased leasing activity.

-  During the quarter ended December 31, 2011, the Company paid to shareholders a quarterly dividend in the amount of $0.315 per share for its common stock. The Company’s dividend payout percentage for the twelve months ended December 31, 2011 was 80% of Core FFO and 107% of AFFO.

Operations                                     

- On a same store square footage leased basis, our portfolio was 88.3% leased as of December 31, 2011 as compared to 89.1% leased as of December 31, 2010. On a square footage leased basis, our total office portfolio was 86.5% leased as of December 31, 2011, as compared to 89.2% as of December 31, 2010. The decrease in the office portfolio leased percentage during the last several quarters is primarily related to the addition to the portfolio of several properties with significant vacancies, including 500 West Monroe Street in Chicago, IL, 1200 Enclave Parkway in Houston, TX, The Medici in Atlanta, GA, Suwanee Gateway One in Suwanee, GA, and 400 TownPark in Lake Mary, FL. Removing these value-add properties from the total portfolio statistics results in an 89.1% leased rate for our stabilized assets at December 31, 2011 as compared to an 89.9% leased rate at December 31, 2010. The primary reason for the decline in the leased rate for our stabilized assets between December 31, 2010 and December 31, 2011 is the net loss of 250,000 leased square feet associated with the Zurich American Insurance Company lease expiration at Windy Point II in Schaumburg, IL. Please refer to page 23 for additional information.

-  The weighted average remaining lease term of our portfolio was 6.4 years⁽²⁾ as of December 31, 2011 as compared to 5.8 years at December 31, 2010.

-  During the three months ended December 31, 2011, the Company completed 939,000 square feet of leasing at our 79 consolidated office properties. We executed renewal leases for 358,000 square feet and new tenant leases for 581,000 square feet, bringing the year-to-date total office leasing activity to 3,869,000 square feet for our wholly-owned portfolio and 3,966,000 square feet including leasing activity associated with our joint venture properties. We did not execute any new leases during the year for our two industrial properties. The average committed capital cost for our wholly-owned portfolio was $5.40 per square foot per year of lease term in 2011. Average committed capital cost per square foot per year of lease term for renewal leases signed during the twelve months ended December 31, 2011 was $5.11 and average committed capital cost per square foot per year of lease term for new leases signed during the same time period was $5.76. During the year, 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 would be $2.80, consistent with our historical average.

-  During the three months ended December 31, 2011, we retained⁽³⁾ tenants for 67% of the square footage associated with expiring leases. During the twelve months ended December 31, 2011, we retained tenants for 70% of the square footage associated with expiring leases. This result compares to a 72% retention rate for the year ended December 31, 2010.

⁽¹⁾FFO, Core FFO and AFFO are supplemental non-GAAP financial measures. See pages 35-36 for definitions of non-GAAP financial measures. See pages 14 and 38 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 December 31, 2011) is weighted based on Annualized Lease Revenue, as defined on page 35.

⁽³⁾Piedmont defines a retained tenant to include an existing tenant/occupant signing a lease for the premises it currently occupies or a tenant whose occupancy of a space is structured in a way to eliminate downtime for the space. Excluding the Zurich American Insurance Company lease expiration at Windy Point II in Schaumburg, IL, our retention rate for the twelve months ended December 31, 2011, would have been 74%.

Leasing Update                                        

- As of September 30, 2011, there were six tenants whose leases contributed greater than 1% to our Annualized Lease Revenue and were scheduled to expire during the fourth quarter of 2011 or the eighteen month period following the end of the fourth quarter of 2011. Information regarding the leasing status of the spaces associated with those tenants’ leases is presented below.

Tenant Name	Property	Property Location	Square Footage (1)	Percentage of Current Quarter Annualized Lease Revenue (%)	Expiration (2)	Current Leasing Status
Kirkland & Ellis	Aon Center	Chicago, IL	331,887	1.8%	Q4 2011	Kirkland & Ellis is vacating. KPMG has leased 69% of the space currently leased to Kirkland & Ellis beginning in August 2012.

As of December 31, 2011

Financing and Capital Activity            

-  As of December 31, 2011, our ratio of gross debt to total gross assets was 27.5%, our ratio of gross debt to gross real estate assets was 31.9%, and our ratio of gross debt to total market capitalization was 33.4%. These debt ratios are based on total principal amount outstanding for our various loans at December 31, 2011. Subsequent to quarter end, we repaid the $140 million loan secured by 500 West Monroe Street. Our pro forma leverage ratios, after adjusting for the repayment of that debt, are: 25.5% for gross debt to total gross assets, 29.8% for gross debt to gross real estate assets, and 31.2% for gross debt to total market capitalization.

-  On November 10, 2011, Piedmont completed the purchase of 400 TownPark, a 176,000 square foot, five-story office building in suburban Orlando, FL. The purchase price was $23.9 million, or $136 per square foot. The construction of the building was completed in 2008 with an efficient, LEED design. The building was 19% leased at acquisition and was 30% leased as of December 31, 2011. It is located within the amenity-rich, mixed-use development of TownPark, which is located adjacent to Interstate 4 in the Lake Mary suburb of Orlando. The building offers the only contiguous block of vacant space over 50,000 square feet in the market. The low cost basis and high-quality construction of the building should afford the Company a competitive advantage in securing a large corporate user as the economy recovers.

-  On December 15, 2011, Piedmont completed the sale of its 96.5% ownership interest in 35 West Wacker Drive, a 1,118,000 square foot, 50-story trophy office building in Chicago, IL. The ownership interest was sold for approximately $387.0 million, which equates to a gross value for the building of $401.0 million, or $359 per square foot. The operating income for the asset is presented in discontinued operations. Piedmont recorded a gain on the sale of its ownership interest in 35 West Wacker Drive of $96.1 million. Through the sale, Piedmont was able to reduce its concentration in Chicago as well as reduce the amount of the Company’s secured debt borrowings, while simultaneously securing an attractive sale price for the ownership interest.

-  On November 17, 2011, Piedmont repaid a $45 million mezzanine loan secured by an equity ownership interest in 500 West Monroe Street located in Chicago, IL. Piedmont was successful in negotiating a $1.1 million discount to the repayment of that obligation which is recorded in gain on early extinguishment of debt in the accompanying financial statements.

-  On November 22, 2011, Piedmont obtained a $300 million, five-year unsecured term loan. The loan has a stated variable interest rate based upon LIBOR and the credit rating of the Company; however, prior to closing on the loan, Piedmont entered into interest rate swap agreements with several counterparties, effectively fixing the interest rate for the loan at 2.69% for the entire five-year term, assuming no credit rating change for the Company. Proceeds from the loan were used to replace a $250 million unsecured term loan which was paid off in June 2011 and for general corporate purposes.

-  On November 2, 2011, the Board of Directors of Piedmont authorized the repurchase of up to $300 million of the Company’s common stock over the next two years. Any repurchases of shares of common stock will depend upon market conditions, as well as other factors, and such repurchases will be made at the discretion of the Company. During the fourth quarter of 2011, the company repurchased 199,400 shares at an average price of $16.24 per share.

-  During the fourth quarter of 2011, Piedmont executed a development contract to construct a 1.4 Megawatt solar canopy at 400 Bridgewater Crossing in Bridgewater, NJ. The project, once completed, will be comprised of 5,850 solar panels. The project represents a $7 million investment in clean energy and complements Piedmont’s existing environmental responsibility initiatives, including its LEED and Energy Star certification efforts.

-  On November 2, 2011, the Board of Directors of Piedmont declared dividends for the fourth quarter of 2011 in the amount of $0.315 per common share outstanding to stockholders of record as of the close of business on December 1, 2011. The dividends were paid on December 22, 2011.

Subsequent Events                              

- On January 9, 2012, Piedmont repaid a $140 million loan secured by 500 West Monroe Street in Chicago, IL. The loan was open to prepayment without any yield maintenance requirements. The repayment of the loan allowed Piedmont to further it’s strategic objective of decreasing its secured debt borrowings in relation to its total borrowings. Please see Financing and Capital Activity above for pro forma leverage ratios, which take into account the repayment of this debt.

Guidance for 2012                               

- The following financial guidance for calendar year 2012 is based on management’s expectations at this time:

	Low        High
Core Funds from Operations	$234   -  $250 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, including the disposition of 35 West Wacker Drive which contributed approximately $0.13 per share of funds from operations in 2011. 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 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.

⁽²⁾Please refer to page 33 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. As of the first quarter of 2011, net debt includes $185 million of secured debt associated with 500 West Monroe Street which was acquired March 31, 2011; $45 million of that debt was repaid during the fourth quarter of 2011. Each quarter prior to the fourth quarter of 2011 includes $120 million of debt associated with one sold asset, 35 West Wacker Drive.

⁽⁴⁾Core EBITDA margin is calculated as Core EBITDA divided by total revenues (including revenues associated with discontinued operations).

⁽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 any of the periods presented.

⁽⁶⁾The change in Piedmont’s debt coverage ratios during 2011 was primarily attributable to $185 million of additional debt assumed with the acquisition of 500 West Monroe Street in March 2011 and the related interest expense; $45 million of this debt was repaid on November 17, 2011, and the remaining $140 million was repaid subsequent to quarter end on January 9, 2012.

⁽⁷⁾Core EBITDA is annualized for the purposes of this calculation.

⁽¹⁾On January 22, 2010, we filed an amendment to our charter to effect a recapitalization of our common stock as described further in our Securities and Exchange Commission (“SEC”) filings. The recapitalization had the effect of a one-for-three reverse stock split. All prior period per share data has been restated to give net effect to this one-for-three reverse stock split.

⁽¹⁾ Includes amounts attributable to wholly-owned properties, including discontinued operations, and our proportionate share of amounts attributable to unconsolidated joint ventures.

⁽²⁾Acquisitions consist of Suwanee Gateway One in Suwanee, GA, purchased on September 28, 2010, Meridian Crossings in Richfield, MN, purchased on October 1, 2010, 1200 Enclave Parkway in Houston, TX, purchased on March 30, 2011, 500 West Monroe Street in Chicago, IL, acquired on March 31, 2011, The Dupree in Atlanta, GA, purchased on April 29, 2011, The Medici in Atlanta, GA, purchased on June 7, 2011, 225 and 235 Presidential Way in Woburn, MA, purchased on September 13, 2011, and 400 TownPark in Lake Mary, FL purchased on November 10, 2011.

⁽³⁾Dispositions consist of 111 Sylvan Avenue in Englewood Cliffs, NJ, sold on December 8, 2010, Eastpointe Corporate Center in Issaquah, WA, sold on July 1, 2011, 5000 Corporate Court in Holtsville, NY, sold on August 31, 2011, and 35 West Wacker Drive in Chicago, IL, sold on December 15, 2011.

⁽⁴⁾The decrease in Chicago Same Store Net Operating Income for the three months ended December 31, 2011 as compared to the same period in 2010 was primarily related to the expiration of the Zurich American Insurance Company lease at Windy Point II in Schaumburg, IL.

⁽⁵⁾The decrease in Washington, D.C. Same Store Net Operating Income for the three months and the twelve months ended December 31, 2011 as compared to the same periods in 2010 was primarily related to a 46,000 square foot lease termination at the beginning of the first quarter of 2011 at 1201 Eye Street in Washington, D.C. (which space is now being used as swing space for NASA) as well as the expiration of a 41,000 square foot lease during the first quarter of 2011 at 11109 Sunset Hills Road in Reston, VA. The decrease in Washington, D.C. Same Store Net Operating Income for the three and the twelve months ended December 31, 2011 was offset somewhat by increased revenue at One Independence Square in Washington, D.C. due to an increased rental rate for Comptroller of the Currency.

⁽⁶⁾The increase in New York Same Store Net Operating Income for the twelve months ended December 31, 2011 as compared to the same period in 2010 was primarily related to rental rate increases (offset by rental abatement concessions in 2010) associated with the lease extension/restructure with the State of New York at 60 Broad Street in New York, NY.

⁽⁷⁾ The decrease in Minneapolis Same Store Net Operating Income for the twelve months ended December 31, 2011 as compared to the same period in 2010 was primarily related to an 80,000 square foot partial lease termination by US Bank during the second quarter of 2011 at US Bancorp Center in Minneapolis, MN, as well as the net partial lease termination for 13,000 square feet by a tenant at Crescent Ridge II in Minnetonka, MN.

⁽⁸⁾ The increase in Los Angeles Same Store Net Operating Income for the three months ended December 31, 2011 as compared to the same period in 2010 was primarily related to a rental abatement in 2010 associated with the Nestle lease renewal at 800 North Brand Boulevard in Glendale, CA. The decrease in Los Angeles Same Store Net Operating Income for the twelve months ended December 31, 2011 as compared to the same period in 2010 was primarily due to a rental abatement concession in 2011 associated with a long-term lease renewal with Panasonic at 26200 Enterprise Way in Lake Forest, CA, and the expiration of a lease, resulting in a net decrease in leased square footage of 58,000 square feet, at 1055 East Colorado Boulevard in Pasadena, CA.

⁽⁹⁾ The decrease in Boston Same Store Net Operating Income for the three months and the twelve months ended December 31, 2011 as compared to the same periods in 2010 was primarily due to a rental abatement concession associated with a long-term lease renewal with State Street Bank at 1200 Crown Colony Drive in Quincy, MA.

⁽¹⁰⁾ The decrease in Other Same Store Net Operating Income for the three months ended December 31, 2011 as compared to the same period in 2010 was primarily attributable to two factors: 1) a rental abatement concession in 2011 associated with a new lease with Chrysler Group, LLC and the related early termination of the previous lease at 1075 West Entrance Drive in Auburn Hills, MI, and 2) a rental abatement concession in 2011 associated with a new lease at Desert Canyon 300 in Phoenix, AZ. The decrease in Other Same Store Net Operating Income for the twelve months ended December 31, 2011 as compared to the same period in 2010 was primarily attributable to the factors listed above, in addition to: 3) reduced rental rates achieved on new and renewal leases which commenced in late 2010 and early 2011 at 150 West Jefferson in Detroit, MI, and 4) a lease contraction of approximately 91,000 square feet effective third quarter 2010 at Chandler Forum in Chandler, AZ.

⁽⁴⁾ The decrease in Chicago Same Store Net Operating Income for the three months and the twelve months ended December 31, 2011 as compared to the same periods in 2010 was primarily related to the expiration of the Zurich American Insurance Company lease at Windy Point II in Schaumburg, IL.

⁽⁵⁾ The decrease in the New York Same Store Net Operating Income for the three months and the twelve months ended December 31, 2011 as compared to the same periods in 2010 was primarily related to partial lease terminations with sanofi-aventis at 200 & 400 Bridgewater Crossing in Bridgewater, NJ in order to allow for the execution of new leases to backfill the terminated spaces in advance of the near-term sanofi-aventis lease expirations.

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 capital 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”; and 2) provides a year-over-year comparison of leased percentage on the same subset of properties under the heading “Same Store Analysis”.

⁽¹⁾The population analyzed consists of office leases executed during the period (retail leases, as well as leases associated with storage spaces, management offices, industrial properties and unconsolidated joint venture assets, were excluded from this analysis). Spaces that had been vacant for greater than one year 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. This assumption is made based upon the historical tenant improvement allowance usage patterns of the Company’s tenants.

⁽⁵⁾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. Leases signed with Piedmont entities are excluded from the analysis.

NOTE: The information presented on this page is for all consolidated assets, inclusive of our industrial properties. During the third quarter of 2011, Piedmont revised its definitions of incremental and non-incremental capital expenditures in order to conform with the more broadly accepted definitions for such terms by other office REITs. Our revised definitions of these measures can be found on pages 35 and 36. Capital expenditures have been restated for all prior periods in order to provide a consistent basis for comparison.

⁽¹⁾ Commitments are unexpired contractual tenant improvement obligations for leases executed in current and prior periods that have not yet been incurred and have not otherwise been presented on Piedmont’s financial statements. The four largest commitments total approximately $75.8 million, or 53% of total outstanding commitments.

⁽²⁾On December 15, 2011, Piedmont completed the sale of its 96.5% ownership interest in 35 West Wacker Drive. A total of $34.6 million of tenant improvement commitments associated with 35 West Wacker Drive has been deducted from total tenant improvement commitments outstanding as of December 31, 2011.

⁽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. 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, l5-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 would be $2.80.

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 within pages 38-40.

Adjusted Funds From Operations (“AFFO”): AFFO is calculated by deducting from Core FFO non-incremental capital expenditures 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 have 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 industrial properties and 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 extraordinary 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 extraordinary 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.

Core Net Operating Income (“Core NOI”): Core NOI is defined as real estate operating income with the add-back of corporate general and administrative expense, depreciation and amortization, and casualty 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. Core 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.

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.

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.

Supplemental Definitions

NOI from Unconsolidated Joint Ventures: NOI from Unconsolidated Joint Ventures is defined as Core NOI attributable to our interests in eight 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.

Same Store Net Operating Income (“Same Store NOI”): Same Store NOI is calculated as the Core 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 industrial properties and 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 stabilized properties’ operating performance. 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 industrial properties and unconsolidated joint venture assets. We believe Same Store Properties is an important measure of comparison of our stabilized portfolio performance.

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: our ability to successfully identify and consummate suitable acquisitions; current adverse market and economic conditions; 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; changes in the economies and other conditions of the office market in general and of the specific markets in which we operate; economic and regulatory changes; additional risks and costs associated with directly managing properties occupied by government tenants; adverse market and economic conditions and related impairments to our assets, including, but not limited to, receivables, real estate assets and other intangible assets; the success of our real estate strategies and investment objectives; availability of financing; costs of complying with governmental laws and regulations; uncertainties associated with environmental and other regulatory matters; our ability to continue to qualify as a REIT under the Internal Revenue Code; the impact of outstanding or potential litigation; 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.
