• Domain 11 and Third + Shoal began operations during the fourth quarter of 2018. Domain 11 and Third + Shoal are both located in Austin, Texas. Domain 11 is 97.5% leased and Third + Shoal is 100% leased.

• Development on Domain 10 commenced in October 2018. Domain 10 will contain 300,000 rentable square feet and is located in Austin, Texas, adjacent to our other Domain properties. Domain 10 was 48.3% leased as of December 31, 2018, and increased to 59.9% leased subsequent to December 31, 2018.

However, the ultimate timing and amounts to be collected for the remaining claims are currently undetermined.

_______________________________

(1) In periods of net loss there are no dilutive securities and diluted loss per common share is calculated using weighted average common shares outstanding - basic as the denominator.

(2) Based on the closing price of our common stock as of the last day of the associated period.

Notes:

Occupancy % represents the total square footage subject to commenced leases as of the reporting date as a percentage of the total rentable square feet (at our ownership interest).

Executed % SF leased represents the total square footage subject to commenced leases plus the square footage for currently vacant space that is subject to executed leases that have not commenced as of the reporting date as a percentage of the total rentable square feet (at our ownership interest).

Economic % SF leased represents the total square footage subject to commenced leases as of the reporting date adjusted to exclude the square footage associated with leases receiving rental abatements as a percentage of the total rentable square feet (at our ownership interest).

Average effective rent represents 12 times the sum of the monthly contractual amounts for base rent and the pro rata budgeted operating expense reimbursements, as of period end, related to leases in place as of period end, as reduced for free rent and excluding any scheduled future rent increases, as adjusted for our ownership interest, divided by the total square footage under commenced leases at period end.

This section includes non-GAAP financial measures, which are accompanied by what we consider the most directly comparable financial measures calculated and presented in accordance with accounting principles generally accepted in the United States (“GAAP”). Quantitative reconciliations of the differences between the non-GAAP financial measures presented and the most directly comparable GAAP financial measures are shown on pages 6-7. 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 on pages 29-30.

We provided rent abatements and concessions to tenants at the Eldridge Properties as a result of Hurricane Harvey through the second quarter of 2018. The rent abatements and concessions were offset by business interruption and other insurance proceeds, net of a deductible and estimated saved expenses as detailed below:

(1) Includes our pro rata share of consolidated and unconsolidated amounts, including for our period of ownership of properties sold.

(2) Interest rate swaps are adjusted to fair value through other comprehensive income (loss). However, because our interest rate swaps do not have a LIBOR floor while the hedged debt is subject to a LIBOR floor, the portion of the change in fair value of our interest rate swaps attributable to this mismatch is reclassified to interest rate hedge ineffectiveness income within “interest expense” on our consolidated statements of operations. We adopted new accounting guidance on January 1, 2018, that eliminates the requirement to separately measure and report hedge ineffectiveness income.

(3) We had a non-recourse loan in default that subjected us to incur default interest at a rate that was 500 basis points higher than the stated interest rate. The ownership of this property was conveyed to the lender in August 2018.

Our Domain 2 and Domain 7 properties (two properties in which we acquired full ownership in January 2017) are reflected above as consolidated and at 100% ownership in all periods presented. Our Domain 8 property is reflected as unconsolidated and at the prior year ownership percentage of 50% for the three-month comparison periods presented above. Domain 8 became operational in the third quarter of 2017 and we acquired full ownership on March 30, 2018. Legacy Union One was acquired in June 2017, and is included in the three-month comparison periods presented above. For additional information regarding the non-GAAP measures, see pages 29-30.
(1) We provided rent abatements and concessions to tenants at the Eldridge Properties as a result of Hurricane Harvey through the second quarter of 2018. The rent abatements and concessions were offset by business interruption and other insurance proceeds recognized, net of a deductible and estimated saved expenses. See page 6 for details. The timing difference between rent abatements and concessions provided and business interruption and other insurance proceeds recognized for the Eldridge Properties was a significant driver to the increase in Same Store NOI and Same Store Cash NOI in 2018 as compared to 2017. Excluding the Eldridge Properties, Same Store NOI and Same Store Cash NOI increases over prior year same periods would be as follows:
Increase in Same Store NOI (excluding Eldridge Properties)										1.4	%										1.7	%
Increase in Same Store Cash NOI (excluding Eldridge Properties)										4.1	%										8.7	%

Notes:

Analysis relates to operating properties owned at the end of the period and reflects TIER REIT’s ownership %.

Occupancy includes all leases for tenants under lease contracts that have commenced during the period.

Rates for expiring leases relate to the lease previously occupying the specific space for which positive absorption was shown or the current lease rate if it is a first generation lease.

Net Rent is equal to the fixed base rental amount paid under the terms of the lease less any portion used to offset real estate taxes, utility charges, and other operating expenses incurred in connection with the leased space.

Cash Net Rent disregards any free rent periods. Therefore, the rate shown is first full monthly cash rent paid.

The impact of short term temporary leasing activity is excluded from the analysis of % increase of Cash Net Rent and % increase of Straight-lined Net Rent.

Definitions of Non-GAAP Financial Measures

We use non-GAAP financial measures in our public filings and other public disclosures. These non-GAAP financial measures are defined below.

Funds from Operations (FFO)

Historical cost accounting for real estate assets in accordance with GAAP implicitly assumes that the value of real estate diminishes predictably over time.  Since real estate values have historically risen or fallen with market conditions, many industry investors and analysts have considered the presentation of operating results for real estate companies that use historical cost accounting alone to be insufficient for evaluating operating performance.  FFO is a non-GAAP financial measure that is widely recognized as a measure of a REIT’s operating performance.  We use FFO as defined by the National Association of Real Estate Investment Trusts (“Nareit”), which is net income (loss), computed in accordance with GAAP, excluding gains (or losses) from sales of property and impairments of depreciable real estate (including impairments of investments in unconsolidated entities that resulted from measurable decreases in the fair value of the depreciable real estate held by the unconsolidated entity), plus depreciation and amortization of real estate assets, and after related adjustments for unconsolidated entities and noncontrolling interests.  The determination of whether impairment charges have been incurred is based partly on anticipated operating performance and hold periods.  Estimated undiscounted cash flows from a property, derived from estimated future net rental and lease revenues, net proceeds on the sale of the property, and certain other ancillary cash flows, are taken into account in determining whether an impairment charge has been incurred.  While impairment charges for depreciable real estate are excluded from net income (loss) in the calculation of FFO as described above, impairments reflect a decline in the value of the applicable property that we may not recover.

We believe that the use of FFO, together with the required GAAP presentations, is helpful in understanding our operating performance because it excludes real estate-related depreciation and amortization, gains and losses from property dispositions, and impairments of depreciable real estate assets, and as a result, when compared period to period, reflects the impact on operations from trends in occupancy rates, rental rates, operating costs, development activities, general and administrative expenses, and interest costs, which are not immediately apparent from net income.  Factors that impact FFO include fixed costs, yields on cash held in accounts, income from portfolio properties and other portfolio assets, interest rates on debt financing, and operating expenses.

We also evaluate FFO, excluding certain items. The items excluded relate to certain non-operating activities or certain non-recurring activities that may create significant FFO volatility and affect the comparability of FFO across periods. We believe it is useful to evaluate FFO excluding these items because it provides useful information in analyzing comparability between reporting periods and in assessing the sustainability of our operating performance.

FFO and FFO, excluding certain items, should not be considered as alternatives to net income (loss), or as indicators of our liquidity, nor are they indicative of funds available to fund our cash needs, including our ability to make distributions.  Additionally, the exclusion of impairments limits the usefulness of FFO and FFO, excluding certain items, as historical operating performance measures since an impairment charge indicates that operating performance has been permanently affected.  FFO and FFO, excluding certain items, are non-GAAP measurements and should be reviewed in connection with other GAAP measurements.  Our FFO and FFO, excluding certain items, as presented may not be comparable to amounts calculated by other REITs that do not define FFO in accordance with the current Nareit definition, or interpret it differently, or that identify and exclude different items related to non-operating activities or certain non-recurring activities.

Net Operating Income (NOI)

NOI is a non-GAAP financial measure equal to rental revenue, less property operating expenses, real estate taxes, and property management expenses.   Our management uses NOI internally as a performance measure and believes NOI is useful to investors as a performance measure because NOI reflects only those income and expense items that are incurred at the property level and is therefore a useful measure for evaluating a property’s performance. Using NOI on a comparative basis allows investors to evaluate property level performance to compare the operating performance of our properties in a given market with the operating performance of other real estate companies in the same market, and consequently allocate their own investment capital accordingly.

Further, we use NOI internally as a performance measure and believe NOI is useful to investors as a performance measure because, when compared year over year, NOI reflects the impact on operations from trends in occupancy rates, rental rates, operating costs, acquisition and development activities, and general and administrative expenses on an un-leveraged basis, providing perspective not immediately apparent from net income. NOI excludes certain components from net income in order to provide results that are more closely related to a property’s results of operations. Certain items such as interest expense, while included in net income, do not affect the operating performance of a real estate asset and are often incurred at the corporate level as opposed to the property level. In addition, it is useful to our management and investors that depreciation and amortization are excluded from NOI because historical cost accounting for real estate assets implicitly assumes that the value of real estate assets diminishes predictably over time, and, instead, real estate values have historically risen or fallen with market conditions.

NOI presented by us may not be comparable to NOI reported by other REITs that do not define NOI exactly as we do. We believe that in order to facilitate a clear understanding of our operating results, NOI should be examined in conjunction with net income as presented in our consolidated financial statements and notes thereto. NOI should not be considered as an alternative to net income as an indication of our performance, or to cash flows as a measure of liquidity or our ability to make distributions.

Same Store NOI and Same Store Cash NOI

Same Store NOI is equal to rental revenue, less lease termination fee income, property operating expenses (excluding tenant improvement demolition costs), real estate taxes, and property management expenses for our same store properties and is considered a non-GAAP financial measure. Same Store Cash NOI is equal to Same Store NOI less non-cash revenue items including straight-line rent adjustments and the amortization of above- and below-market rent. The same store properties include our operating office properties not held for sale and owned and operated for the entirety of both periods being compared and include our comparable ownership percentage in each period for properties in which we own an unconsolidated interest that is accounted for using the equity method.  We view Same Store NOI and Same Store Cash NOI as important measures of the operating performance of our properties because they allow us to compare operating results of properties owned and operated for the entirety of both periods being compared and therefore eliminate variations caused by acquisitions or dispositions during such periods.

Supplemental Operating and Financial Data 4Q’18 Page 29

Same Store NOI and Same Store Cash NOI presented by us may not be comparable to Same Store NOI or Same Store Cash NOI reported by other REITs that do not define Same Store NOI or Same Store Cash NOI exactly as we do. We believe that in order to facilitate a clear understanding of our operating results, Same Store NOI and Same Store Cash NOI should be examined in conjunction with net income (loss) as presented in our consolidated financial statements and notes thereto. Same Store NOI and Same Store Cash NOI should not be considered as an indicator of our ability to make distributions, as alternatives to net income (loss) as an indication of our performance, or as a measure of cash flows or liquidity.

Earnings before Interest, Taxes, Depreciation and Amortization for Real Estate (EBITDAre)

EBITDAre is a non-GAAP financial measure. We use EBITDAre as defined by Nareit which is net income (loss), computed in accordance with GAAP, plus interest expense, plus income tax expense, plus depreciation and amortization expense, plus (minus) losses and gains on the disposition of depreciated property, including losses and gains on change of control, plus impairment write-downs of depreciated property, and after related adjustments for unconsolidated entities. Our EBITDAre as presented may not be comparable to amounts calculated by other REITs that do not define EBITDAre in accordance with the current Nareit definition, or interpret it differently than we do.

EBITDAre is not intended to represent cash flow for the period, is not presented as an alternative to operating income as an indicator of operating performance, should not be considered in isolation or as a substitute for measures of performance prepared in accordance with GAAP, and is not indicative of operating income or cash provided by operating activities as determined under GAAP. EBITDAre is presented solely as a supplemental disclosure with respect to liquidity because we believe it provides useful information regarding our ability to service or incur debt.

We also evaluate Adjusted EBITDAre, which is EBITDAre excluding certain revenues and operating expenses. The items excluded relate to certain non-operating activities or certain non-recurring activities that create significant EBITDAre volatility. Further, we evaluate Adjusted Estimated Full Period EBITDAre, which is EBITDAre excluding certain revenues and operating expenses and adjusted to show the pro forma impact of properties that were either acquired or disposed during the period. We believe it is useful to evaluate EBITDAre excluding these items and as adjusted for property acquisitions and dispositions because it provides useful information in analyzing comparability between reporting periods and in assessing the sustainability of our operating performance.
