Table of Contents This supplemental package contains certain statements that 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. 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 2016 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, 2015 and subsequently filed periodic reports.

Reconciliation of Net Income to Net Operating Income (based on GAAP rents) and Same Store Net Operating Income (based on GAAP rents) Three Months Ended

Supplemental Information - Q2 2016 36 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. Same Store Net Operating Income (“Same Store NOI”): Same Store NOI is calculated as the NOI attributable to the properties owned or placed in service during the entire span of the current and prior year reporting periods. 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. 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. 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. Annualized Lease Revenue (“ALR”): ALR is the sum of (i) annualized rental payments (defined as base rent plus operating expense reimbursements, excluding rental abatements) for executed and commenced leases as well as leases executed but not yet commenced for vacant space, and (ii) annualized parking revenues, payable either under the terms of an executed lease or vendor contract. ALR excludes rental payments for executed leases that have not yet commenced for space covered by an existing lease. 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. Definitions - Other 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. Columbia Property Trust, Inc. Definitions - Non-GAAP Financial Measures 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. 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.
