Definitions and Reconciliations

Non-GAAP financial measures and other capitalized terms, as used in this earnings release, are defined, reconciled and further explained on Attachment 12, Definitions and Reconciliations of Non-GAAP Financial Measures and Other Terms. Attachment 12 is included in the full earnings release available at the Company’s website at http://www.avalonbay.com/earnings. This wire distribution includes only the following definitions and reconciliations.

AVB Residential Benchmark represents the average monthly revenue collections as a percentage of amounts billed for the referenced day of the month for the period from April 2019 to March 2020.

Average Rental Rates are calculated by the Company as Residential rental revenue in accordance with GAAP, divided by the weighted average number of occupied apartment homes.

Commercial represents results attributable to the non-apartment components of the Company's mixed-use communities and other non-residential operations.

Development is composed of consolidated communities that are either currently under construction, or were under construction and were completed during the current year. These communities may be partially or fully complete and operating.

Economic Occupancy (“Ec Occ”) is defined as total possible Residential revenue less vacancy loss as a percentage of total possible Residential revenue. Total possible Residential revenue (also known as “gross potential”) is determined by valuing occupied units at contract rates and vacant units at Market Rents. Vacancy loss is determined by valuing vacant units at current Market Rents. By measuring vacant apartments at their Market Rents, Economic Occupancy takes into account the fact that apartment homes of different sizes and locations within a community have different economic impacts on a community’s gross revenue.

Economic Gain is calculated by the Company as the gain on sale in accordance with GAAP, less accumulated depreciation through the date of sale and any other adjustments that may be required under GAAP accounting. Management generally considers Economic Gain to be an appropriate supplemental measure to gain on sale in accordance with GAAP because it helps investors to understand the relationship between the cash proceeds from a sale and the cash invested in the sold community. The Economic Gain for disposed communities is based on their respective final settlement statements. A reconciliation of the aggregate Economic Gain to the aggregate gain on sale in accordance with GAAP for the wholly-owned operating communities disposed of during the nine months ended September 30, 2021 is as follows (dollars in thousands):

EBITDA, EBITDAre and Core EBITDAre are considered by management to be supplemental measures of our financial performance. EBITDA is defined by the Company as net income or loss attributable to the Company before interest expense, income taxes, depreciation and amortization. EBITDAre is calculated by the Company in accordance with the definition adopted by the Board of Governors of the National Association of Real Estate Investment Trusts (“Nareit”), as EBITDA plus or minus losses and gains on the disposition of depreciated property, plus impairment write-downs of depreciated property, with adjustments to reflect the Company's share of EBITDAre of unconsolidated entities. Core EBITDAre is the Company’s EBITDAre as adjusted for non-core items outlined in the table below. By further adjusting for items that are not considered part of the Company’s core business operations, Core EBITDAre can help one compare the core operating and financial performance of the Company between periods. A reconciliation of EBITDA, EBITDAre and Core EBITDAre to net income is as follows (dollars in thousands):

FFO and Core FFO are considered by management to be supplemental measures of our operating and financial performance. FFO is calculated by the Company in accordance with the definition adopted by Nareit. FFO is calculated by the Company as Net income or loss attributable to common stockholders computed in accordance with GAAP, adjusted for gains or losses on sales of previously depreciated operating communities, cumulative effect of a change in accounting principle, impairment write-downs of depreciable real estate assets, write-downs of investments in affiliates which are driven by a decrease in the value of depreciable real estate assets held by the affiliate and depreciation of real estate assets, including adjustments for unconsolidated partnerships and joint ventures. By excluding gains or losses related to dispositions of previously depreciated operating communities and excluding real estate depreciation (which can vary among owners of identical assets in similar condition based on historical cost accounting and useful life estimates), FFO can help one compare the operating and financial performance of a company’s real estate between periods or as compared to different companies. Core FFO is the Company's FFO as adjusted for non-core items outlined in the table below. By further adjusting for items that are not considered by us to be part of our core business operations, Core FFO can help one compare the core operating and financial performance of the Company between periods. A reconciliation of Net income attributable to common stockholders to FFO and to Core FFO is as follows (dollars in thousands):

Initial Year Market Cap Rate is defined by the Company as Projected NOI of a single community for the first 12 months of operations (assuming no repositioning), less estimates for non-routine allowance of approximately $300 - $500 per apartment home, divided by the gross sales price for the community. Projected NOI, as referred to above, represents management’s estimate of projected rental revenue minus projected operating expenses before interest, income taxes (if any), depreciation and amortization. For this purpose, management’s projection of operating expenses for the community includes a management fee of 2.25%. The Initial Year Market Cap Rate, which may be determined in a different manner by others, is a measure frequently used in the real estate industry when determining the appropriate purchase price for a property or estimating the value for a property. Buyers may assign different Initial Year Market Cap Rates to different communities when determining the appropriate value because they (i) may project different rates of change in operating expenses and capital expenditure estimates and (ii) may project different rates of change in future rental revenue due to different estimates for changes in rent and occupancy levels. The weighted average Initial Year Market Cap Rate is weighted based on the gross sales price of each community.

Interest Coverage is calculated by the Company as Core EBITDAre, divided by the sum of interest expense, net, and preferred dividends, if applicable. Interest Coverage is presented by the Company because it provides rating agencies and investors an additional means of comparing our ability to service debt obligations to that of other companies. A calculation of Interest Coverage for the three months ended September 30, 2021 is as follows (dollars in thousands):

Market Rents as reported by the Company are based on the current market rates set by the Company based on its experience in renting apartments and publicly available market data. Trends in Market Rents for a region as reported by others could vary. Market Rents for a period are based on the average Market Rents during that period and do not reflect any impact for cash concessions.

Net Debt-to-Core EBITDAre is calculated by the Company as total debt (secured and unsecured notes and the Company's variable rate unsecured credit facility) that is consolidated for financial reporting purposes, less consolidated cash and cash in escrow, divided by annualized third quarter 2021 Core EBITDAre, as adjusted. A calculation of Net Debt-to-Core EBITDAre is as follows (dollars in thousands):

NOI is defined by the Company as total property revenue less direct property operating expenses (including property taxes), and excluding corporate-level income (including management, development and other fees), corporate-level property management and other indirect operating expenses, expensed transaction, development and other pursuit costs, net of recoveries, interest expense, net, loss (gain) on extinguishment of debt, net, general and administrative expense, joint venture (income) loss, depreciation expense, corporate income tax expense (benefit), casualty and impairment loss (gain), net, gain on sale of communities, (gain) loss on other real estate transactions, net for-sale condominium activity and net operating income from real estate assets sold or held for sale. The Company considers NOI to be an important and appropriate supplemental performance measure to Net Income of operating performance of a community or communities because it helps both investors and management to understand the core operations of a community or communities prior to the allocation of any corporate-level property management overhead or financing-related costs. NOI reflects the operating performance of a community, and allows for an easier comparison of the operating performance of individual assets or groups of assets. In addition, because prospective buyers of real estate have different financing and overhead structures, with varying marginal impact to overhead as a result of acquiring real estate, NOI is considered by many in the real estate industry to be a useful measure for determining the value of a real estate asset or groups of assets.

Residential NOI represents results attributable to the Company's apartment rental operations, including parking and other ancillary Residential revenue. A reconciliation of Residential NOI to Net Income, as well as a breakdown of Residential NOI by operating segment, is as follows (dollars in thousands):

NOI as reported by the Company does not include the operating results from assets sold or classified as held for sale. A reconciliation of NOI from communities sold or classified as held for sale is as follows (dollars in thousands):

Commercial NOI is composed of the following components (in thousands):

Other Stabilized is composed of completed consolidated communities that the Company owns, which have Stabilized Operations as of January 1, 2021, or which were acquired subsequent to January 1, 2020. Other Stabilized excludes communities that are conducting or are probable to conduct substantial redevelopment activities.

Projected FFO and Projected Core FFO, as provided within this release in the Company’s outlook, are calculated on a basis consistent with historical FFO and Core FFO, and are therefore considered to be appropriate supplemental measures to projected Net Income from projected operating performance. A reconciliation of the ranges provided for Projected FFO per share (diluted) for the fourth quarter and full year 2021 to the ranges provided for projected EPS (diluted) and corresponding reconciliation of the ranges for Projected FFO per share to the ranges for Projected Core FFO per share are as follows:

Projected NOI, as used within this release for certain Development communities and in calculating the Initial Year Market Cap Rate for dispositions, represents management’s estimate, as of the date of this release (or as of the date of the buyer’s valuation in the case of dispositions), of projected stabilized rental revenue minus projected stabilized operating expenses. For Development communities, Projected NOI is calculated based on the first twelve months of Stabilized Operations following the completion of construction. In calculating the Initial Year Market Cap Rate, Projected NOI for dispositions is calculated for the first twelve months following the date of the buyer’s valuation. Projected stabilized rental revenue represents management’s estimate of projected gross potential minus projected stabilized economic vacancy and adjusted for projected stabilized concessions plus projected stabilized other rental revenue. Projected stabilized operating expenses do not include interest, income taxes (if any), depreciation or amortization, or any allocation of corporate-level property management overhead or general and administrative costs. In addition, projected stabilized operating expenses for Development communities do not include property management fee expense. Projected gross potential for Development communities and dispositions is generally based on leased rents for occupied homes and management’s best estimate of rental levels for homes which are currently unleased, as well as those homes which will become available for lease during the twelve month forward period used to develop Projected NOI. The weighted average Projected NOI as a percentage of Total Capital Cost ("Weighted Average Initial Projected Stabilized Yield") is weighted based on the Company’s share of the Total Capital Cost of each community, based on its percentage ownership.

Management believes that Projected NOI of the Development communities, on an aggregated weighted average basis, assists investors in understanding management's estimate of the likely impact on operations of the Development communities when the assets are complete and achieve stabilized occupancy (before allocation of any corporate-level property management overhead, general and administrative costs or interest expense). However, in this release the Company has not given a projection of NOI on a company-wide basis. Given the different dates and fiscal years for which NOI is projected for these communities, the projected allocation of corporate-level property management overhead, general and administrative costs and interest expense to communities under development is complex, impractical to develop, and may not be meaningful. Projected NOI of these communities is not a projection of the Company's overall financial performance or cash flow. There can be no assurance that the communities under development will achieve the Projected NOI as described in this release.

Redevelopment is composed of consolidated communities where substantial redevelopment is in progress or is probable to begin during the current year. Redevelopment is considered substantial when (i) capital invested during the reconstruction effort is expected to exceed the lesser of $5,000,000 or 10% of the community’s pre-redevelopment basis and (ii) physical occupancy is below or is expected to be below 90% during or as a result of the redevelopment activity. Redevelopment includes one community containing 344 apartment homes that is currently under active redevelopment as of September 30, 2021.

Residential Rental Revenue with Concessions on a Cash Basis is considered by the Company to be a supplemental measure to Residential rental revenue in conformity with GAAP to help investors evaluate the impact of both current and historical concessions on GAAP-based Residential rental revenue and to more readily enable comparisons to revenue as reported by other companies. In addition, Residential Rental Revenue with Concessions on a Cash Basis allows an investor to understand the historical trend in cash concessions.

A reconciliation of Same Store Residential rental revenue in conformity with GAAP to Residential Rental Revenue with Concessions on a Cash Basis is as follows (dollars in thousands):

Residential represents results attributable to the Company's apartment rental operations, including parking and other ancillary Residential revenue.

Same Store is composed of consolidated communities in the markets where the Company has a significant presence and where a comparison of operating results from the prior year to the current year is meaningful, as these communities were owned and had Stabilized Operations, as defined below, as of the beginning of the respective prior year period. Therefore, for 2021 operating results, Same Store is composed of consolidated communities that have Stabilized Operations as of January 1, 2020, are not conducting or are not probable to conduct substantial redevelopment activities and are not held for sale or probable for disposition within the current year.

Same Store Collections are the collection rates based on individual resident and commercial tenant activity as reflected in the Company’s property management systems, and are presented to provide information about collections trends during the COVID-19 pandemic. Prior to the COVID-19 pandemic, the collections information provided was not routinely produced for internal use by senior management or publicly disclosed by the Company, and is a result of analysis that is not subject to internal controls over financial reporting. This information is not prepared in accordance with GAAP, does not reflect GAAP revenue or cash flow metrics, may be subject to adjustment in preparing GAAP revenue and cash flow metrics at the end of the three and nine months ended September 30, 2021. Additionally, this information should not be interpreted as predicting the Company’s financial performance, results of operations or liquidity for any period.

Stabilized Operations/Restabilized Operations is defined as the earlier of (i) attainment of 90% physical occupancy or (ii) the one-year anniversary of completion of development or redevelopment.

Total Capital Cost includes all capitalized costs projected to be or actually incurred to develop the respective Development or Redevelopment community, including land acquisition costs, construction costs, real estate taxes, capitalized interest and loan fees, permits, professional fees, allocated development overhead and other regulatory fees, offset by proceeds from the sale of any associated land or improvements, all as determined in accordance with GAAP. Total Capital Cost also includes costs incurred related to first generation commercial tenants, such as tenant improvements and leasing commissions. For Redevelopment communities, Total Capital Cost excludes costs incurred prior to the start of redevelopment when indicated. With respect to communities where development or redevelopment was completed in a prior or the current period, Total Capital Cost reflects the actual cost incurred, plus any contingency estimate made by management. Total Capital Cost for communities identified as having joint venture ownership, either during construction or upon construction completion, represents the total projected joint venture contribution amount. For joint ventures not in construction, Total Capital Cost is equal to gross real estate cost.

Unconsolidated Development is composed of communities that are either currently under construction, or were under construction and were completed during the current year, in which we have an indirect ownership interest through our investment interest in an unconsolidated joint venture. These communities may be partially or fully complete and operating.

Unencumbered NOI as calculated by the Company represents NOI generated by real estate assets unencumbered by outstanding secured notes payable as of September 30, 2021 as a percentage of total NOI generated by real estate assets. The Company believes that current and prospective unsecured creditors of the Company view Unencumbered NOI as one indication of the borrowing capacity of the Company. Therefore, when reviewed together with the Company’s Interest Coverage, EBITDA and cash flow from operations, the Company believes that investors and creditors view Unencumbered NOI as a useful supplemental measure for determining the financial flexibility of an entity. A calculation of Unencumbered NOI for the nine months ended September 30, 2021 is as follows (dollars in thousands):
