(2) | The amounts reported represent the “compensation actually paid” to each of Mr. Schall and Mr. Naughton and the average “compensation actually paid” to each of the other NEOs as a group, each computed in accordance with Item 402(v) of Regulation S-K, but do not reflect the actual amount of compensation earned by or paid to such NEOs. In accordance with Item 402(v) of Regulation S-K, the following adjustments were made to the amounts reported in the “Total” column of the Summary Compensation Table to calculate “compensation actually paid.”
(3) | Mr. Naughton served as Chief Executive Officer from 2012 through January 2, 2022 and served as Executive Chairman throughout 2022. He served as a non-executive chairman in 2023.

While we consider numerous financial and non-financial performance measures for the purpose of evaluating and determining executive compensation, we consider Core FFO per share, which is one of the measures used to determine annual cash incentive compensation for our NEOs, to be the most important performance measure used to link compensation actually paid to the NEOs for fiscal year 2023 to Company performance.

Additional 402(v) Disclosure [Text Block] |  | For AvalonBay, the “compensation actually paid” to our NEOs for a given year, as calculated in accordance with Item 402(v) of Regulation S-K, includes cash amounts paid for service, the value of other items included in “all other compensation” in the Summary Compensation Table, the change in the fair value of unvested equity awards during the year (through year end or at any earlier vesting date) and the year-end fair value of equity awards granted during the year that remain unvested at year end. In this way, “compensation actually paid” takes into account changes in the fair value of equity awards using closing stock prices and Monte Carlo values. Our equity awards consisted of restricted shares of Common Stock, stock options, and multi-year performance awards that are earned based upon the achievement of TSR and operating metrics. Accordingly, the “compensation actually paid” to our NEOs as reported in the table below was greatly influenced by the value of our Common Stock price, which varied over the measurement period as illustrated in the following table:
Fiscal Year End | Closing Stock Price | Year over Year Change
December 29, 2023 | $187.22 | 16%
December 30, 2022 | $161.52 | -36%
December 31, 2021 | $252.59 | 57%

[1] | Non-PEO NEOs for 2023 and 2022 include Messrs. O’Shea, Birenbaum, Breslin, and Schulman.
[2] | The amounts reported represent the “compensation actually paid” to each of Mr. Schall and Mr. Naughton and the average “compensation actually paid” to each of the other NEOs as a group, each computed in accordance with Item 402(v) of Regulation S-K, but do not reflect the actual amount of compensation earned by or paid to such NEOs. In accordance with Item 402(v) of Regulation S-K, the following adjustments were made to the amounts reported in the “Total” column of the Summary Compensation Table to calculate “compensation actually paid.”
[3] | Non-PEO NEOs for 2021 include Messrs. O’Shea, Schall, Birenbaum, and Breslin.
[4] | Non-PEO NEOs for 2020 include Messrs. O’Shea, Birenbaum, and Breslin and William M. McLaughlin, our former Executive Vice President, Development and Construction.
[5] | Company TSR and Peer Group TSR are calculated using the measurement period beginning on the last trading day of 2019, through and including the end of the fiscal year for which cumulative Company TSR or cumulative Peer Group TSR is being calculated.
[6] | Represents the weighted peer group TSR, weighted according to the respective companies’ stock market capitalization at the beginning of each period. The peer group used for this purpose is the FTSE NAREIT Apartment REIT Index, a published industry index.
[7] | The dollar amounts reported represent the amount of net income reflected in the Company’s audited financial statements for the applicable fiscal year.
[8] | The Company Selected Measure is Core FFO per share, representing the Company’s FFO as adjusted for non-core items. By 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. While we consider numerous financial and non-financial performance measures for the purpose of evaluating and determining executive compensation, we consider Core FFO per share, which is one of the measures used to determine annual cash incentive compensation for our NEOs, to be the most important performance measure used to link compensation actually paid to the NEOs for fiscal year 2023 to Company performance.
[9] | The amounts reported represent the sum of the amounts reported in the “Stock Awards” and “Option Awards” columns of the Summary Compensation Table for the applicable fiscal year.
[10] | No awards granted during a fiscal year vested that same year.
[11] | Represents the sum of the following for each equity award that was outstanding (unvested) as of December 31 of the applicable fiscal year and December 31 of the prior fiscal year: the difference between (x) the fair value of such award as of December 31 of the applicable fiscal year and (y) the fair value of such award as of December 31 of the prior fiscal year. For performance awards, the fair value represents the Monte Carlo valuation for the TSR portion and the payout corresponding to the interim level of achievement of the operating metrics portion. For options, fair value represents the Black-Scholes value.
[12] | For a multi-year performance award that matured (vested) on December 31 of the reported year, the fair value was the number of units earned valued at the closing price of a share of Common Stock on the last trading day of that year, plus the cash amount in respect of accrued dividends to be paid out upon settlement.
[13] | Mr. Schall joined AvalonBay as President and a director in January 2021 and became Chief Executive Officer effective January 3, 2022. Mr. Schall’s compensation for 2021 is included in the non-PEO averages.
[14] | Mr. Naughton served as Chief Executive Officer from 2012 through January 2, 2022 and served as Executive Chairman throughout 2022. He served as a non-executive chairman in 2023.
