Net income was $74.7 million, or $0.61 per diluted share, for the first quarter of 2017, compared with $6.7 million, or $0.05 per diluted share, in the prior-year period, primarily due to gains on sales of real estate in the current period.

Guidance for 2017:

For the year ending December 31, 2017, the Company expects to report Net Income in the range of $0.78 to $0.85 per diluted share, and Normalized FFO in a range of $1.15 to $1.22 per diluted share.

A reconciliation of projected Net Income Available to Common Stockholders per diluted share to projected FFO and Normalized FFO per diluted share is provided as follows:

	Full Year
	2017 Range
	Low			High
Net income	$	0.78		$	0.85
Real estate depreciation & amortization	0.97			0.97
Gain on sale of real estate assets	(0.60		)	(0.60		)
FFO	1.15			1.22
Loss on early extinguishment of debt	—			—
Normalized FFO	$	1.15		$	1.22

Our guidance for 2017 is based on the following assumptions for our portfolio:

• Leased percentage at year end 2017 of 93% to 95%

• GAAP straight-line rental income of $35 million to $40 million

• G&A of $35 million to $37 million

• $539.5 million of properties were sold in January 2017. Assumes no further dispositions except for the transfer of the 263 Shuman Boulevard property to the lender in settlement of the $49.0 million mortgage note.

• Acquisitions of $500 million

• Weighted average diluted share count of 122.5 million

These estimates reflect management’s view of current market conditions and incorporate certain economic and operational assumptions and projections. This annual guidance includes the continued enhancement of the portfolio based on the above assumptions. Actual results could differ from these estimates. Note that individual quarters may fluctuate on both a cash basis and a GAAP basis due to the timing of acquisitions and dispositions, 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.

Definitions:

Funds From Operations ("FFO") - FFO, as defined by the National Association of Real Estate Investment Trusts (NAREIT), represents net income (computed in accordance with GAAP), plus depreciation of real estate assets and amortization of lease-related costs, excluding gains

(losses) on sales of real estate and impairment losses on real estate assets. The Company computes FFO in accordance with NAREIT's definition, which may differ from the methodology for calculating FFO, or similarly titled measures, used by other companies and this may not be comparable to those presentations. We consider FFO an appropriate supplemental performance measure given its wide use by and relevance to investors and analysts. FFO, reflecting the assumption that real estate asset values rise or fall with market conditions, principally adjusts for the effects of GAAP depreciation and amortization of real estate assets, which assume that the value of real estate diminishes predictably over time.

Normalized FFO - We calculate Normalized FFO by starting with FFO, as defined by NAREIT, and adjusting for certain items that are not reflective of our core operations, including: (i) real estate acquisition-related costs, (ii) listing costs, (iii) loss on interest rate swaps and (iv) loss on early extinguishment of debt. Such items create significant earnings volatility. We believe Normalized FFO provides a meaningful measure of our operating performance and more predictability regarding future earnings potential. Normalized 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 Normalized FFO.

Adjusted Funds from Operations - AFFO is calculated by adjusting Cash Flow from Operations to exclude (i) changes in assets and liabilities resulting from timing differences (ii) additional amortization of lease assets (liabilities), (iii) straight-line rental income, (iv) gain (loss) on interest rate swaps, (v) recurring capital expenditures, and adding back (vi) stock based compensation expense and (vii) non-cash interest expense. Because AFFO adjusts for income and expenses that we believe are not reflective of our core operations, we believe AFFO provides useful supplemental information. AFFO is a non-GAAP financial measure and should not be viewed as an alternative measurement of our operating performance to net cash flows from operating activities or net income.

EBITDA - EBITDA is defined as net income before interest, taxes, depreciation and amortization. We believe EBITDA is a reasonable measure of our liquidity. 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 EBITDA differently and our calculation should not be compared to that of other REITs.

Adjusted EBITDA - Adjusted 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, real estate acquisition-related costs, discontinued operations adjustments, 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 adjusted EBITDA is a reasonable measure of our liquidity. Adjusted 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 adjusted EBITDA differently and our calculation should not be compared to that of other REITs.

Net Operating Income (based on cash rents) - NOI - cash rents is defined as Adjusted EBITDA adjusted for (i) portfolio general and administrative expense, (ii) interest rate swap valuation adjustments, (iii) interest expense associated with interest rates swaps, (iv) non-cash property operations, (v) straight-line rental income, and (vi) net effect of above/(below) market amortization. The company uses this measure to assess its operating results and believes it is important in assessing operating performance. NOI - cash rents 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.

Net Operating Income (based on GAAP Rents) - NOI - GAAP rents is defined as Adjusted EBITDA adjusted for (i) portfolio general and administrative expense, (ii) interest rate swap valuation adjustments, and (iii) interest expense associated with interest rates swaps. The company uses this measure to assess its operating results and believes it is important in assessing operating performance. NOI - GAAP rents 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 NOI attributable to the properties continuously owned and operating for the entirety of the reporting periods presented. 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.

Forward-Looking Statements:

Certain statements contained in this press release other than historical facts may be considered forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. We intend for all such forward-looking statements to be covered by the applicable safe harbor provisions for forward-looking statements contained in those acts. Such statements include, in particular, statements about our plans, strategies, guidance, and prospects and are subject to certain risks and uncertainties, including 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," "estimate," "believe," "continue," or other similar words. Readers are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date of this press release. We make no representations or warranties (express or implied) about the accuracy of any such forward-looking statements contained in this press release, 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.

Any such forward-looking statements are subject to risks, uncertainties, and other factors and are based on a number of assumptions involving judgments with respect to, among other things, future economic, competitive, and market conditions, all of which are difficult or impossible to predict accurately. To the extent that our assumptions differ from actual conditions, our ability to accurately anticipate results expressed in such forward-looking statements, including our ability to generate positive cash flow from operations, make distributions to stockholders, and maintain the value of our real estate properties, may be significantly hindered. See Item 1A in the Company's most recently filed Annual Report on Form 10-K for the year ended December 31, 2016 and subsequently filed periodic reports for a discussion of some of the risks and uncertainties that could cause actual results to differ materially from those presented in our forward-looking statements. The risk factors described in our Annual Report are not the only ones we face, but do represent those risks and uncertainties that we believe are material to us. Additional risks and uncertainties not currently known to us or that we currently deem immaterial may also harm our business.

Such forward-looking statements can generally be identified by our use of forward-looking terminology such as “may,” “will,” “expect,” “intend,” “anticipate,” “estimate,” “believe,” “continue,” or other similar words. Readers are cautioned not to place undue reliance on these forward-looking statements, including our 2017 guidance, which speak only as of the date this supplemental package is published, and which are subject to certain risks and uncertainties which could cause actual results to differ materially from those projected or anticipated. These risks and uncertainties include, without limitation: general risks affecting the real estate industry (including, without limitation, the inability to enter into or renew leases, dependence on tenants’ financial condition, and competition from other owners and operators of real estate); adverse economic or real estate developments in the company’s target markets; risks associated with the availability and terms of financing, the use of debt to fund acquisitions, and the ability to refinance indebtedness as it comes due; reductions in asset valuations and related impairment charges; risks associated with downturns in foreign, domestic and local economies, changes in interest rates; potential liability for uninsured losses and environmental contamination; risks associated with joint ventures; risks associated with the company’s potential failure to qualify as a REIT under the Internal Revenue Code of 1986, as amended, and possible adverse changes in tax and environmental laws; and risks associated with the company’s dependence on key personnel whose continued service is not guaranteed. We do not intend to publicly update or revise any forward-looking statements, whether as a result of new information, future events, or otherwise. For additional risks and uncertainties that would cause actual results to differ materially from those presented in our forward-looking statements see our Annual Report on Form 10-K for the year ended December 31, 2016 and subsequently filed periodic reports.

As of March 31, 2017, CXP owned interests in 16 operating properties, of which 15 are wholly-owned and one is owned through an unconsolidated joint venture. CXP owns a 51% interest in the Market Square buildings and related $325 million mortgage note through an unconsolidated joint venture. When evaluating the Company’s performance and capital resources, management considers the financial impact of investments held directly and through unconsolidated joint ventures. This report includes financial and operational information for our wholly-owned investments and our proportional interest in unconsolidated investments. We do not control the Market Square Joint Venture and recognize that proportional financial data may not accurately depict all of the legal and economic implications of our interest in this joint venture. Select Portfolio Statistics exclude 263 Shuman Boulevard, as we are in process of transferring this property to its lender. In January 2017, the lender put the $49.0 million 263 Shuman Boulevard mortgage note into a non-monetary default because the full-building lease with OfficeMax was not renewed, as is required by the loan agreement. Portfolio Notes: Columbia Property Trust (NYSE: CXP) owns and operates Class-A office buildings primarily in competitive CBD locations within high-barrier-to- entry markets. As of March 31, 2017, our $4 billion portfolio included 16 operating properties containing 7.8 million square feet, concentrated in San Francisco, New York, Atlanta and Washington, D.C.

Supplemental Information - Q1 2017 14 (5) Columbia Property Trust is party to an interest rate swap agreement, which effectively fixes its interest rate on the $150 Million Term Loan at 3.52% per annum and terminates on July 29, 2022. The spread of 1.55% over the swapped rate is based on the company's credit rating.

Maintenance Capital: Capital expenditures incurred to maintain the building structure and functionality, and to lease space at our properties in their current condition. Maintenance capital excludes capital for recent acquisitions and first generation leasing. Investment Capital: Capital expenditures incurred to lease space to first generation tenants; to lease space that has been vacant for more than one year; to expand or repurpose building functionality in our existing portfolio; and to bring properties up to our ownership standards. We establish our ownership standards based on Class A office property characteristics typical for the respective local market, including level of finishes, systems, accessibility, and defined market presence. All costs incurred within 36 months of acquisition are considered Investment Capital. Funds From Operations (“FFO”): FFO, as defined by the National Association of Real Estate Investment Trusts (“NAREIT”), represents net income (computed in accordance with GAAP), plus depreciation of real estate assets and amortization of lease-related costs, excluding gains (losses) on sales of real estate and impairment losses on real estate assets. The Company computes FFO in accordance with NAREIT's definition, which may differ from the methodology for calculating FFO, or similarly titled measures, used by other companies and this may not be comparable to those presentations. We consider FFO an appropriate supplemental performance measure given its wide use by and relevance to investors and analysts. FFO, reflecting the assumption that real estate asset values rise or fall with market conditions, principally adjusts for the effects of GAAP depreciation and amortization of real estate assets, which assume that the value of real estate diminishes predictably over time. Normalized FFO: We calculate Normalized FFO by starting with FFO, as defined by NAREIT, and adjusting for certain items that are not reflective of our core operations, including: (i) real estate acquisition-related costs, (ii) listing costs, (iii) loss on interest rate swaps and (iv) loss on early extinguishment of debt. Such items create significant earnings volatility. We believe Normalized FFO provides a meaningful measure of our operating performance and more predictability regarding future earnings potential. Normalized 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 Normalized FFO. Net Operating Income (based on cash rents) (“NOI - cash rents”): NOI - cash rents is defined as Adjusted EBITDA adjusted for (i) portfolio general and administrative expense, (ii) interest rate swap valuation adjustments, (iii) interest expense associated with interest rates swaps, (iv) non-cash property operations, (v) straight-line rental income, and (vi) net effect of above/(below) market amortization. The company uses this measure to assess its operating results and believes it is important in assessing operating performance. NOI - cash rents 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. Net Operating Income (based on GAAP rents) (“NOI - GAAP rents”): NOI - GAAP rents is defined as Adjusted EBITDA adjusted for (i) portfolio general and administrative expense, (ii) interest rate swap valuation adjustments, and (iii) interest expense associated with interest rates swaps. The company uses this measure to assess its operating results and believes it is important in assessing operating performance. NOI - GAAP rents 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 NOI attributable to the properties continuously owned and operating for the entirety of the reporting periods presented. 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. Definitions - Other EBITDA: EBITDA is defined as net income before interest, taxes, depreciation and amortization. We believe EBITDA is a reasonable measure of our liquidity. 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 EBITDA differently and our calculation should not be compared to that of other REITs. Columbia Property Trust, Inc. Definitions - Non-GAAP Financial Measures Included in this supplemental report are non-GAAP financial measures, which are accompanied by what we consider the most directly comparable financial measures calculated and presented in accordance with GAAP. These measures include earnings (or components of earnings), as defined, from both continuing operations and discontinued operations. A description of the non-GAAP financial measures we present and a statement of the reasons why management believes the non-GAAP measures provide useful information to investors about the company's financial condition and results of operations can be found below. Adjusted Funds From Operations (“AFFO”): AFFO is calculated by adjusting Cash Flow from Operations to exclude (i) changes in assets and liabilities resulting from timing differences (ii) additional amortization of lease assets (liabilities), (iii) straight-line rental income, (iv) gain (loss) on interest rate swaps, (v) recurring capital expenditures, and adding back (vi) stock based compensation expense and (vii) non-cash interest expense. Because AFFO adjusts for income and expenses that we believe are not reflective of our core operations, we believe AFFO provides useful supplemental information. AFFO is a non-GAAP financial measure and should not be viewed as an alternative measurement of our operating performance to net cash flows from operating activities or net income. Adjusted EBITDA: Adjusted 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, real estate acquisition-related costs, discontinued operations adjustments, 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 adjusted EBITDA is a reasonable measure of our liquidity. Adjusted 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 adjusted EBITDA differently and our calculation should not be compared to that of other REITs.
