Adjusted Funds From Operations attributable to common stockholders (“AFFO”): Adjusted funds from operation, or AFFO, is presented in addition to FFO. AFFO is defined as FFO, excluding certain non-cash operating revenues and expenses, acquisition and transaction related costs for transactions not completed and recurring capitalized expenditures. Recurring capitalized expenditures includes expenditures required to maintain and re-tenant our properties, tenant improvements and leasing commissions. AFFO further adjusts FFO for certain other non-cash items, including the amortization or accretion of above or below market rents included in revenues, straight line rent adjustments, impairment losses, non-cash equity compensation and non-cash interest expense. We believe AFFO provides a useful supplemental measure of our operating performance because it provides a consistent comparison of our operating performance across time periods that is comparable for each type of real estate investment and is consistent with management’s analysis of the operating performance of our properties. As a result, we believe that the use of AFFO, together with the required GAAP presentations, provide a more complete understanding of our operating performance. As with FFO, our reported AFFO may not be comparable to other REITs’ AFFO, should not be used as a measure of our liquidity, and is not indicative of our funds available for our cash needs, including our ability to pay dividends.

EBITDA: We believe that earnings before interest, taxes, depreciation and amortization, or EBITDA, is helpful to investors as a supplemental measure of our operating performance as a real estate company because it is a direct measure of the actual operating results of our industrial properties. We also use this measure in ratios to compare our performance to that of our industry peers.

Funds From Operations attributable to common stockholders (“FFO”): Funds from operations, or FFO, is a non-GAAP financial measure that is widely recognized as a measure of REIT operating performance. We consider FFO to be an appropriate supplemental measure of our operating performance as it is based on a net income analysis of property portfolio performance that excludes non-cash items such as depreciation. The historical accounting convention used for real estate assets requires straight-line depreciation of buildings and improvements, which implies that the value of real estate assets diminishes predictably over time. Since real estate values rise and fall with market conditions, presentations of operating results for a REIT, using historical accounting for depreciation, could be less informative. We define FFO, consistent with the National Association of Real Estate Investment Trusts, or NAREIT, definition, as net income, computed in accordance with GAAP, excluding gains (or losses) from sales of property, depreciation and amortization of real estate assets, impairment losses and after adjustments for unconsolidated partnerships and joint ventures. Adjustments for unconsolidated partnerships and joint ventures will be calculated to reflect FFO on the same basis. Other equity REITs may not calculate FFO (in accordance with the NAREIT definition) as we do, and, accordingly, our FFO may not be comparable to such other REITs’ FFO. FFO should not be used as a measure of our liquidity, and is not indicative of funds available for our cash needs, including our ability to pay dividends.

GAAP: U.S generally accepted accounting principles.

Gross assets: the carrying amount of total assets plus accumulated depreciation and amortization, as reported in the Company’s consolidated financial statements. For gross assets as of December 31, 2017, the calculation is as follows:

* Balance of accumulated amortization relating to the intangible lease assets can be found within Footnote 6 of our 2017 Annual Report on Form 10-K.

Net Operating Income (NOI): We consider net operating income, or NOI, to be an appropriate supplemental measure to net income because it helps both investors and management understand the core operations of our properties. We define NOI as total revenue (including rental revenue, tenant reimbursements, management, leasing and development services revenue and other income) less property-level operating expenses including allocated overhead. NOI excludes depreciation and amortization, general and administrative expenses, impairments, gain/loss on sale of real estate, interest expense, and other non-operating items.

Non-Recurring Capital Expenditures: Non-recurring capital expenditures include capital expenditures of long lived improvements required to upgrade/replace existing systems or items that previously did not exist.

Occupancy: We define occupany as the percentage of total leasable square footage in which either the sooner of lease term commencement or revenue recognition in accordance to GAAP has commenced as of the close of the reporting period.

Recurring Capital Expenditures: Recurring capitalized expenditures includes capital expenditures required to maintain and re-tenant our properties, tenant improvements and leasing commissions.

Same Store Portfolio: Our Same Property Portfolio is a subset of our consolidated portfolio and includes properties that were wholly-owned by us as of January 1, 2016, and still owned by us as of December 31, 2017. Therefore, we excluded from our Same Store Portfolio any properties that were acquired or sold during the period from January 1, 2016 through December 31, 2017. The Company's computation of same store NOI may not be comparable to other REITs.

Weighted average lease term remaining: The average contractual lease term remaining as of the close of the reporting period (in years) weighted by square footage.
