Share Incentive Plans

12.Share Incentive Plans

Any Common Shares issued pursuant to EQR’s incentive equity compensation and employee share purchase plans will result in ERPOP issuing OP Units to EQR on a one-for-one basis with ERPOP receiving the net cash proceeds of such issuances.

Overview of Share Incentive Plans

The 2019 Share Incentive Plan (the “2019 Plan”), as approved by the Company’s shareholders on June 27, 2019, expires on June 27, 2029 and reserves 11,331,958 Common Shares for issuance. All future awards will be granted under the 2019 Plan. As of December 31, 2023, 8,213,508 shares were available for future issuance.

Pursuant to the 2019 Plan and the 2011 Share Incentive Plan (the “2011 Plan”) (collectively the “Share Incentive Plans”), officers, trustees, key employees and consultants of the Company and its subsidiaries may be granted share options to acquire Common Shares (“Options”), including non-qualified share options (“NQSOs”), incentive share options (“ISOs”) and share appreciation rights (“SARs”), or may be granted restricted or non-restricted shares/units (including long-term incentive plan awards), subject to conditions and restrictions. Options, SARs, restricted shares and restricted units are sometimes collectively referred to herein as “Awards.”

The 2011 Plan will terminate when all outstanding Awards have expired or have been exercised/vested. The Board of Trustees may at any time amend or terminate the Share Incentive Plans, but termination will not affect Awards previously granted, absent immediate vesting and cash settlement. Any Options which had vested prior to such a termination would remain exercisable by the holder.

Employee Long-Term Compensation Awards

The following table summarizes the terms of Awards generally granted to employees:

	Options	Restricted Shares	Restricted Units
Overview	Options exercised after vesting result in issuance of new Common Shares.	Restricted shareholders generally have the same voting rights and receive quarterly dividend payments on their shares at the same rate and on the same date as any other Common Share holder (1).	When certain conditions are met, restricted units convert into an equal number of OP Units, which the holder may exchange for Common Shares on a one-for-one basis or at the option of the Company the cash value of such shares. Restricted unitholders receive quarterly distribution payments on their restricted units at the same rate and on the same date as any other OP Unit holder (1).
Grant/Exercise Price	Granted at the fair market value of Common Shares as of the grant date using the Black-Scholes model as described below.	Granted at the fair market value of Common Shares as of the grant date.	Granted at varying discount rates to the fair market value of Common Shares as of the grant date (2).
Vesting Period	In three equal installments over a three-year period from the grant date.	Three years from the grant date.	Three years from the grant date.
Expiration	Ten years from the grant date.	Not applicable.	Ten years from the grant date (2).
Upon Employee Termination	Unvested options are canceled.	Unvested restricted shares are canceled.	Unvested restricted units are canceled.

(1)Dividends/distributions paid on unvested restricted shares and units are included as a component of retained earnings and Noncontrolling Interest – Operating Partnership/Limited Partners Capital, respectively, and have not been considered in reducing net income available to Common Shares/Units in a manner similar to the Company’s preferred share/preference unit dividends for the earnings per share/Unit calculation.

(2)A restricted unit will automatically convert to an OP Unit when the capital account of each restricted unit increases (“books-up”) to a specified target. The probability of a book-up occurring within the ten-year contractual life along with the liquidity risk associated with various hold period restrictions are both reflected in the discount. If the capital target is not attained within ten years following the date of issuance, the restricted unit will automatically be canceled and no compensation will be payable to the holder of such canceled restricted unit. If the capital target is attained and the restricted unit is converted to an OP Unit, it will not expire.

Valuation Method of Share Options

The fair value of the Option grants is recognized over the requisite service/vesting period of the Options. The fair value for the Company’s Options was estimated at the time the Options were granted using the Black-Scholes option pricing model with the primary grant in each year having the following weighted average assumptions:

	2023			2022			2021
Expected volatility (1)		23.8	%		21.7	%		21.3	%
Expected life (2)	5 years			5 years			5 years
Expected dividend yield (3)		3.30	%		3.26	%		3.23	%
Risk-free interest rate (4)		4.04	%		1.66	%		0.50	%
Exercise price per share (5)	$	66.59		$	91.59		$	67.48
Option valuation per share	$	12.67		$	12.57		$	7.96

(1)Expected volatility – Estimated based on the historical five-year volatility (the period matching the expected life) of EQR’s share price measured on a monthly basis.

(2)Expected life – Approximates the actual weighted average life of all Options granted since the Company went public in 1993.

(3)Expected dividend yield – Calculated by averaging the historical annual yield on EQR shares for a period matching the expected life of each grant, with the annual yield calculated by dividing actual regular dividends (excluding any special dividends) by the average price of EQR’s shares in a given year.

(4)Risk-free interest rate – The most current U.S. Treasury rate available at the grant date for a period matching the expected life of each grant.

(5)Exercise price per share – The closing share price of the Common Shares on the grant date.

The valuation method and assumptions are the same as those the Company used in accounting for Option expense in its consolidated financial statements. The Black-Scholes option valuation model was developed for use in estimating the fair value of traded options that have no vesting restrictions and are fully transferable. This model is only one method of valuing options. Because the Company’s Options have characteristics significantly different from those of traded options, and because changes in the subjective input assumptions can materially affect the fair value estimate, the actual value of the Options to the recipient may be significantly different.

Long-Term Incentive Plan

The Company’s executive compensation program allows the Chief Executive Officer and certain other executive officers to earn from 0% to 200% of the target number of long-term incentive (“LTI”) awards, payable in the form of restricted shares and/or restricted units. Additionally, the program allowed participation of Samuel Zell, the Company's former Chairman of the Board of Trustees, prior to his death. No payout would be made for any result below 50% of the target performance metric. The Company’s Total Shareholder Return (“TSR”), Normalized Funds from Operations (“FFO”) and Net Debt to Normalized EBITDAre (Earnings Before Interest, Taxes, Depreciation and Amortization for Real Estate) results over a forward-looking three-year performance period determine the restricted shares and/or restricted units awarded and are compared to pre-established quantitative performance metrics. The grant date fair value of the awards is estimated using a Monte Carlo model for the TSR portion of the awards, and the resulting expense is recorded over the service period regardless of whether the TSR performance measures are achieved, while the Normalized FFO and Net Debt to Normalized EBITDAre portions of the awards are adjusted based on the final achievement obtained. If the executive is retirement-eligible, the grant date fair value is amortized into expense over the first year. All other awards are amortized into expense over the three-year performance and vesting period. If employment is terminated prior to vesting, the restricted shares and restricted units are generally canceled, subject to the retirement benefit provisions discussed below as well as the death and disability provisions of the plan.

The LTI participants receive distributions only on restricted units awarded equal to 10% of the quarterly distributions paid on OP Units during the performance period. At the end of the performance period, LTI participants receive dividends/distributions actually earned on restricted shares or restricted units awarded during the performance period, less any distributions already paid on the restricted units.

The grant date fair value of the TSR portion of the LTI awards is estimated using a multifactor Monte Carlo model to determine share prices for a set of relative awards for which the payout of the award depends on the spread of EQR’s TSR to the TSR of two indices: (a) the FTSE Nareit Apartment Index; and (b) the FTSE Nareit Equity Index. The absolute Company TSR metric previously included in the TSR portion of the LTI awards for which the payout of the award only depended on EQR’s TSR was replaced with a Net Debt to Normalized EBITDAre metric for the 2022 LTI plan and onward, covering a forward-looking three-year performance period. The grant date fair value of the Normalized FFO and Net Debt to Normalized EBITDAre portions of the LTI awards are estimated using the closing price of EQR Common Shares on the grant date for the restricted shares and a discounted closing price of EQR Common Shares on the grant date for the restricted units to reflect the “book-up” and liquidity risk inherent in the units. The individual prices determined above are then weighted to arrive at the final values for each restricted share/unit as follows:

	2023		2022		2021
Weighted average fair value per restricted share	$	61.18	$	96.84	$	61.73
Weighted average fair value per restricted unit	$	58.78	$	93.32	$	59.82

The valuation method and assumptions are the same as those the Company used in accounting for the LTI award expense in its consolidated financial statements. The Monte Carlo valuation model is only one method of valuing awards. Because the Company’s restricted shares/units have characteristics significantly different from those of traded shares/units, and because changes in the subjective input assumptions can materially affect the fair value estimate, the actual value of the restricted shares/units to the recipient may be significantly different.

Trustees

All non-employee Trustees, including the Company’s current Chairman, are granted Options, restricted shares and/or restricted units that vest one year from the grant date that corresponds to the term for which he or she has been elected to serve. The Company's former Chairman of the Board of Trustees, Samuel Zell, did not receive these awards. Since 2016, he only received awards under the LTI plan (see further discussion above).

Retirement Benefits

The Company’s Share Incentive Plans provide for certain benefits upon retirement. The following table summarizes the terms of each retirement eligibility category.

	Age 62 for Employees	Rule of 70 for Employees	Age 72 for Trustees
Eligibility	For employees hired prior to January 1, 2009 and who were age 59 or older as of February 1, 2019.	All employees (1).	All non-employee Trustees.
Effect on unvested restricted shares, restricted units and Options	Awards immediately vest, Options continue to be exercisable for the balance of the applicable ten-year option period and restricted units are still subject to the book-up provisions.	Awards continue to vest per the original vesting schedule, subject to certain conditions, Options continue to be exercisable for the balance of the applicable ten-year option period and restricted units are still subject to the book-up provisions.	Awards immediately vest, Options continue to be exercisable for the balance of the applicable ten-year option period and restricted units are still subject to the book-up provisions.
Effect on LTI Plan	Awards are prorated in proportion to the number of days worked in the first year of the three-year performance period and the individual does not receive any payout of shares or units until the final payout is determined at the end of the three-year performance period.

(1)The Rule of 70 is met when an employee’s years of service with the Company (which must be at least 15 years) plus his or her age (which must be at least 55 years) on the date of termination equals or exceeds 70 years. In addition, the employee must give the Company at least six months’ advance written notice of his or her intention to retire along with agreeing to certain other conditions.

Under the Company’s definitions of retirement, some of its executive officers, including its Chief Executive Officer, are retirement eligible.

(1)The Company allows eligible officers the ability to receive immediately vested restricted units (subject to the book-up provisions described above and a two-year hold restriction) or immediately vested Options in-lieu of any percentage of their annual cash bonus.

Compensation expense is generally recognized for Awards as follows:

•Restricted shares, restricted units and Options – Straight-line method over the vesting period of the Options, shares or units regardless of cliff or ratable vesting distinctions.

•LTI plan awards – Target amount is recognized under the straight-line method over the vesting period of the shares or units.

•ESPP discount – Immediately upon the purchase of Common Shares each quarter.

The Company accelerates the recognition of compensation expense for all Awards for those individuals approaching or meeting the retirement age criteria discussed above. The total compensation expense related to Awards not yet vested at December 31, 2023 is $10.7 million (including the accelerated expenses for individuals approaching or meeting the retirement age criteria discussed above), which is expected to be recognized over a weighted average term of 1.34 years.

The table below summarizes the Award activity of the Share Incentive Plans for the three years ended December 31, 2023, 2022 and 2021:

Vested and expected to vest		611,238		8.54	$	69.80	$	—

(1)The aggregate intrinsic values were calculated as the excess, if any, between the Company’s closing share price of $61.16 per share on December 31, 2023 and the strike price of the underlying awards.

As of December 31, 2022 and 2021, 3,549,325 Options (with a weighted average exercise price of $60.80) and 3,710,888 Options (with a weighted average exercise price of $58.70) were exercisable, respectively.
