On June 16, 2015, at our 2015 annual meeting of shareholders, our shareholders approved the 2015 Incentive Plan. The 2015 Incentive Plan replaced the Equity Commonwealth 2012 Equity Compensation Plan (as amended, the 2012 Plan). The Board of Trustees approved the 2015 Incentive Plan, subject to shareholder approval, on March 18, 2015 (the Effective Date). On January 26, 2016, the Board of Trustees approved an amendment to the 2015 Incentive Plan to allow the Compensation Committee (Committee) to authorize in an award agreement a transfer of all or a part of certain equity awards not for value to a “family member” (as defined in the 2015 Incentive Plan). At our annual meeting of shareholders on June 20, 2019, our shareholders approved an amendment to the 2015 Incentive Plan to increase the number of common shares of beneficial interest authorized thereunder by 2,500,000 (hereafter, as amended, the 2015 Incentive Plan). The following description of certain terms of the 2015 Incentive Plan is qualified in all respects by the terms of the 2015 Incentive Plan.

Eligibility. Awards may be granted under the 2015 Incentive Plan to employees, officers and non-employee directors of the Company, its subsidiaries or its affiliates, or consultants and advisors (who are natural persons) providing services to the Company, its subsidiaries or its affiliates, or any other person whose participation in the 2015 Incentive Plan is determined by the Committee to be in the best interests of the Company.

Recipients of the Company’s restricted shares have the same voting rights as any other common shareholder. During the period of restriction, holders of unvested restricted shares are eligible to receive dividend payments on their shares at the same rate and on the same date as any other common shareholder. The restricted shares are service based awards and vest over a service period determined by the Committee.

Recipients of the Company’s restricted stock units, or RSUs, are entitled to receive dividends with respect to the common shares underlying the RSUs if and when the RSUs are earned, at which time the recipient will be entitled to receive an amount in cash equal to the aggregate amount of cash dividends that would have been paid in respect to the common shares underlying the recipient’s earned RSUs had such common shares been issued to the recipient on the first day of the performance period. To the extent that an award does not vest, the dividends related to unvested RSUs will be forfeited. The RSUs are market-based awards with a service condition and recipients may earn RSUs based on the Company’s total shareholder return, or TSR, relative to the TSRs of the companies that comprise the Nareit Office Index over a three-year performance period. Following the end of the three-year performance period, the number of earned awards will be determined. The earned awards vest in two tranches with 50% of the earned award vesting following the end of the performance period on the date the Committee determines the level of achievement of the performance metric and the remaining 50% of the earned award vesting approximately one year thereafter, subject to the grant recipient’s continued employment. Compensation expense for the RSUs is determined using a Monte Carlo simulation model and is recognized ratably from the grant date to the vesting date of each tranche.

LTIP Units are a class of beneficial interests in the Operating Trust that may be issued to employees, officers or trustees of the Operating Trust, the Company or their subsidiaries, or LTIP Units. Time-based LTIP Units have the same general characteristics as restricted shares and market-based LTIP Units have the same general characteristics as RSUs. Each LTIP Unit will convert automatically into an OP Unit on a one-for-one basis when the LTIP Unit becomes vested and its capital account is equalized with the per-unit capital account of the OP Units. Holders of LTIP Units generally will be entitled to receive the same per-unit distributions as the other outstanding OP Units in the Operating Trust, except that market-based LTIP Units will not participate in distributions until expiration of the applicable performance period, at which time any earned market-based LTIP Units generally will become entitled to receive a catch-up distribution for the periods prior to such time.

On January 25, 2021, the Committee approved grants in the aggregate amount of 122,466 restricted shares and 248,646 RSUs at target (619,750 RSUs at maximum) to the Company’s officers, certain employees, and to Mr. Zell, the Chairman of our Board of Trustees, as part of their compensation for fiscal year 2020. The restricted shares were valued at $28.25 per share, the closing price of our common shares on the NYSE on the grant date.

On June 23, 2021, in accordance with the Company’s compensation plan for independent Trustees, the Committee awarded each of the six independent Trustees $0.1 million in restricted shares or time-based LTIP Units as part of their compensation for the 2021-2022 year of service on the Board of Trustees. These awards equated to 3,701 shares or time-based LTIP Units per Trustee, for a total of 18,505 shares and 3,701 time-based LTIP Units, valued at $27.02 per share and unit, the closing price of our common shares on the New York Stock Exchange, or NYSE, on that day. These shares and time-based LTIP Units vest one year after the date of the award, on June 23, 2022.

During the year ended December 31, 2021, 523,662 RSUs vested, and, as a result, we issued 523,662 common shares, prior to certain employees surrendering their common shares to satisfy tax withholding obligations (see Note 7). Additionally, 81,434 market-based LTIP Units vested and converted into OP Units (see Note 8).

On January 27, 2020, the Committee approved grants in the aggregate amount of 20,116 time-based LTIP Units, 40,841 market-based LTIP Units at target (101,796 market-based LTIP Units at maximum), 85,058 restricted shares and 172,697 RSUs at target (430,447 RSUs at maximum) to the Company’s officers, certain employees and to Mr. Zell, the Chairman of our Board of Trustees, as part of their compensation for fiscal year 2019.

On June 23, 2020, in accordance with the Company’s compensation plan for independent Trustees, the Committee awarded each of the then nine independent Trustees $0.1 million in restricted shares or time-based LTIP Units as part of their compensation for the 2020-2021 year of service on the Board of Trustees. These awards equated to 3,184 shares or time-based LTIP Units per Trustee, for a total of 19,104 shares and 9,552 time-based LTIP Units, valued at $31.41 per share and unit, the closing price of our common shares on the NYSE on that day. These shares and time-based LTIP Units vested on June 23, 2021.

On September 16, 2020, following the resignation of one of our then-existing nine independent trustees, our Board of Trustees appointed a new independent Trustee. In accordance with the Company's compensation plan for independent Trustees, the Committee awarded this Trustee $0.1 million in restricted shares as part of her prorated compensation for the 2020-2021 year of service on the Board of Trustees. This award equated to 2,526 shares valued at $30.39 per share, the closing price of our common shares on the NYSE on that day. These shares vested on June 23, 2021.

During the year ended December 31, 2020, 388,615 RSUs vested, and, as a result, we issued 388,615 common shares, prior to certain employees surrendering their common shares to satisfy tax withholding obligations (see Note 7).

The 341,370 unvested restricted shares and time-based LTIP Units as of December 31, 2021 are scheduled to vest as follows: 134,965 shares/units in 2022, 91,181 shares/units in 2023, 62,206 shares/units in 2024 and 53,018 shares/units in 2025.
