The following table reflects the activity of the General Partner capital for the three months ended March 31, 2021 and 2020, respectively (dollars in thousands):

Any transactions resulting in the issuance of additional common and preferred stock of the General Partner result in a corresponding issuance by the Operating Partnership of an equivalent amount of common and preferred units to the General Partner.

SHARE/UNIT REPURCHASE PROGRAM

In September 2012, the Board of Directors of the General Partner renewed and authorized an increase to the General Partner’s repurchase program (“Repurchase Program”). The General Partner has authorization to repurchase up to $150 million of its outstanding common stock under the renewed Repurchase Program, which it may repurchase from time to time in open market transactions at prevailing prices or through privately negotiated transactions. As of March 31, 2021, the General Partner has repurchased and retired 394,625 shares of its outstanding common stock for an aggregate cost of approximately $11 million (all of which occurred in the year ended December 31, 2012), with a remaining authorization under the Repurchase Program of $139 million. Concurrent with these repurchases, the General Partner sold to the Operating Partnership common units for approximately $11 million.

DIVIDEND REINVESTMENT AND STOCK PURCHASE PLAN

The General Partner has a Dividend Reinvestment and Stock Purchase Plan (the “DRIP”) which commenced in March 1999 under which approximately 5.5 million shares of the General Partner’s common stock have been reserved for future issuance. The DRIP provides for automatic reinvestment of all or a portion of a participant’s dividends from the General Partner’s shares of common stock. The DRIP also permits participants to make optional cash investments up to $5,000 a month without restriction and, if the Company waives this limit, for additional amounts subject to certain restrictions and other conditions set forth in the DRIP prospectus filed as part of the Company’s effective registration statement on Form S-3 filed with the SEC for the approximately 5.5 million shares of the General Partner’s common stock reserved for issuance under the DRIP.

STOCK OPTION PLANS

In May 2013, the General Partner established the 2013 Incentive Stock Plan (the “2013 Plan”) under which a total of 4,600,000 shares have been reserved for issuance. In March 2021, the General Partner granted 950,000 stock options to the chief executive officer as an employment “inducement award” that is intended to comply with New York Stock Exchange Rule 303A.08.

On June 5, 2015, in connection with employment agreements entered into with each of Messrs. Rudin and DeMarco, former chief executive officers (together, the “Executive Employment Agreements”), the Company granted options to purchase a total of 800,000 shares of the General Partner’s common stock, exercisable for a period of ten years with an exercise price equal to the closing price of the General Partner’s common stock on the grant date of $17.31 per share, with 400,000 of such options vesting in three equal annual installments commencing on the first anniversary of the grant date (“Time Vesting Options”) and fully vesting on June 5, 2018, and 400,000 of such options vesting if the General Partner’s common stock traded at or above $25.00 per share for 30 consecutive trading days while the executive is employed (“Price Vesting Options”), or on or before June 30, 2019, subject to certain conditions. The Price Vesting Options vested on July 5, 2016 on account of the price vesting condition being achieved. 

Pursuant to the Letter Agreement in connection with Ms. Gilmartin’s appointment as the Company’s interim Chief Executive Officer, the Company granted to MAG Partners fully vested stock options to purchase up to 230,000 shares of common stock with an exercise

price of $14.39 per share, and up to 100,000 shares of common stock with an exercise price of $20.00 per share, pursuant to the Option Agreement. However, the options, and any shares received upon exercise, will terminate and be forfeited if the Board of Directors ends the Term for “cause” or MAG Partners terminates its arrangement with the Company (including a resignation by Ms. Gilmartin of her appointment as interim Chief Executive Officer, but excluding a termination because of a material breach of the arrangement by the Company or because Ms. Gilmartin has been appointed as the permanent Chief Executive Officer of the Company) before six months have elapsed, or if MAG Partners fails to comply with certain covenants in the Letter Agreement. 157,505 of the options have been granted subject to shareholder approval at the Company’s 2021 Annual Meeting of Stockholders; however, if a “change in control” transaction occurs before the date of such 2021 Annual Meeting, then such options would instead be canceled and cashed out upon such transaction for a value equal to their “spread value,” if any. See Note 13-Commitments and Contingencies.

In connection with his appointment as Chief Executive Officer, Mr. Nia was granted 950,000 stock options on March 10, 2021 that had an exercise price equal to the closing price of the Company’s common stock on the grant date of $15.79 per share.  The stock options will vest in one-third increments on each of the first three anniversaries of the date of grant, subject to earlier vesting on certain termination events. See Note 13-Commitments and Contingencies.

There were no stock options that were exercised under any stock option plans for the three months ended March 31, 2021 and 2020, respectively. The Company has a policy of issuing new shares to satisfy stock option exercises.

As of March 31, 2021 and December 31, 2020, the stock options outstanding had a weighted average remaining contractual life of approximately 6.0 and 3.6 years, respectively.

The Company recognized stock options expense of $114,000 and zero for the three months ended March 31, 2021 and 2020, respectively.

AO LTIP UNITS (Appreciation-Only LTIP Units)

Pursuant to the terms of the DeMarco employment agreement, the Company entered into an AO Long-Term Incentive Plan Award Agreement (the “AO LTIP Award Agreement”) with Mr. DeMarco on March 13, 2019 that provided for the grant to Mr. DeMarco of 625,000 AO LTIP Units. AO LTIP Units are a class of partnership interests in the Operating Partnership that are intended to qualify as “profits interests” for federal income tax purposes and generally only allow the recipient to realize value to the extent the fair market value of a share of Common Stock exceeds the threshold level set at the time the AO LTIP Units are granted, subject to any vesting conditions applicable to the award. The threshold level was fixed at $21.46 in the AO LTIP Award Agreement, the closing price of the Common Stock as reported on the New York Stock Exchange (the “NYSE”) on the date of grant. The value of vested AO LTIP Units is realized through conversion of the AO LTIP Units into common units of limited partnership interests of the Operating Partnership (the “Common Units”). The number of Common Units into which vested AO LTIP Units may be converted is determined based on the quotient of (i) the excess of the fair market value of the Common Stock on the conversion date over the threshold level designated at the time the AO LTIP Unit was granted (i.e., $21.46), divided by (ii) the fair market value of the Common Stock on the conversion date. AO LTIP Units, once vested, have a finite term during which they may be converted into Common Units, within ten years from the grant date of the AO LTIP Units or they are forfeited. In addition, the AO LTIP Units issued to Mr. DeMarco are subject to the following vesting conditions:

(i) 250,000 of the AO LTIP Units shall vest and become exercisable on the earliest date on which the closing price of the Common Stock, as reported on the NYSE, or if the Common Stock is not then traded on the NYSE, then the closing price of the Common Stock on any other securities exchange on which the Common Stock is traded or quoted (the “Securities Market”), has been equal to or greater than $25.00 per share for at least 30 consecutive trading days, provided that such date occurs prior to March 13, 2023 (the “Outside Date”);

(ii) an additional 250,000 of the AO LTIP Units shall vest and become exercisable on the earliest date on which the closing price of the Common Stock, as reported on the NYSE, or if the Common Stock is not then traded on the NYSE, then the closing price of the Common Stock on the Securities Market, has been equal to or greater than $28.00 per share for at least 30 consecutive trading days, provided that such date occurs prior to the Outside Date; and

(iii) an additional 125,000 of the AO LTIP Units shall vest and become exercisable on the earliest date on which the closing price of the Common Stock, as reported on the NYSE, or if the Common Stock is not then traded on the NYSE, then the closing price of the Common Stock on the Securities Market, has been equal to or greater than $31.00 per share for at least 30 consecutive trading days, provided that such date occurs prior to the Outside Date.

Mr. DeMarco will generally receive special income allocations in respect of an AO LTIP Unit equal to 10 percent (or such other percentage specified in the applicable award agreement) of the income allocated in respect of a Common Unit. Upon conversion of AO LTIP Units to Common Units, Mr. DeMarco will be entitled to receive in respect of each such AO LTIP Unit, on a per unit basis, a special cash distribution equal to 10% (or such other percentage specified in the applicable award agreement) of the distributions received

by a holder of an equivalent number of Common Units during the period from the grant date of the AO LTIP Units through the date of conversion. The Company has reserved shares of common stock under the 2013 Plan for issuance upon vesting and conversion of the AO LTIP Units in accordance with their terms and conditions.

As of March 31, 2021, the Company had $1.2 million of total unrecognized compensation cost related to unvested AO LTIP Units granted under the Company’s stock compensation plans. That cost is expected to be recognized over a remaining weighted average period of 1.9 years. The Company recognized AO LTIP unit expense of $155,000 and $155,000 for the three months ended March 31, 2021 and 2020, respectively.

LONG-TERM INCENTIVE PLAN AWARDS

On April 20, 2018, the Company granted LTIP awards to senior management of the Company, including the General Partner’s executive officers (the “2018 LTIP Awards”). All of the 2018 LTIP Awards were in the form of LTIP Units and constitute awards under the 2013 Plan. For Messrs. DeMarco and Tycher, approximately twenty-five percent (25%) of the grant date fair value of the 2018 LTIP Award was in the form of a time-based award that vests after three years on April 20, 2021 (the “2018 TBV LTIP Units”), and the remaining approximately seventy-five percent (75%) of the grant date fair value of the 2018 LTIP Award was in the form of a performance-based award under the Company’s Outperformance Plan (the “2018 OPP”) adopted by the General Partner’s Board of Directors, consisting of a multi-year, performance-based equity compensation plan and related forms of award agreement (the “2018 PBV LTIP Units”). For all other executive officers, approximately fifty percent (50%) of the grant date fair value of the 2018 LTIP Award was in the form of 2018 TBV LTIP Units and the remaining approximately fifty percent (50%) of the grant date fair value of the 2018 LTIP Award was in the form of 2018 PBV LTIP Units. The 2018 TBV LTIP Units vested on April 20, 2021.

The 2018 OPP was designed to align the interests of senior management to relative and absolute performance of the Company over a three year performance period from April 20, 2018 through April 19, 2021. Participants in the 2018 OPP will only earn the full awards if, over the three year performance period, the Company achieves a thirty-six percent (36%) absolute TSR and if the Company’s TSR is in the 75th percentile of performance as compared to the office REITs in the NAREIT index. As the targets for vesting were partially achieved, 31.25 percent of the 2018 PBV LTIP Units vested and the unvested 2018 PBV LTIP Units were forfeited on April 19, 2021.

On March 22, 2019, the Company granted LTIP awards to senior management of the Company, including the General Partner’s executive officers (the “2019 LTIP Awards”). All of the 2019 LTIP Awards were in the form of LTIP Units and constitute awards under the 2013 Plan. For Mr. DeMarco, approximately 25 percent of the target 2019 LTIP Awards were in the form of time-based LTIP Units that vest after three years on March 22, 2022 (the “2019 TBV LTIP Units”), and the remaining approximately 75 percent of the grant date fair value of his 2019 LTIP Award will be in the form of performance-based LTIP Units under the Company’s Outperformance Plan (the “2019 OPP”) adopted by the General Partner’s Board of Directors, consisting of a multi-year, performance-based equity compensation plan and related forms of award agreement (the “2019 PBV LTIP Units”). For Messrs. Tycher, Smetana, Wagner, Cardoso and Hilton, fifty percent (50%) of the grant date fair value of their respective 2019 LTIP Awards is in the form of 2019 TBV LTIP Units and the remaining fifty percent (50%) of the grant date fair value of their respective 2019 LTIP Awards is in the form of 2019 PBV LTIP Units. Mr. DeBari, who was promoted to Chief Accounting Officer on March 13, 2019, received 100 percent of his 2019 LTIP Award in the form of 2019 TBV LTIP Units.

The 2019 OPP was designed to align the interests of senior management to relative and absolute performance of the Company over a three year performance period from March 22, 2019 through March 21, 2022. Participants of performance-based awards in the 2019 OPP will only earn the full awards if, over the three year performance period, the Company achieves a thirty-six percent (36%) absolute total stockholder return (“TSR”) and if the Company’s TSR is in the 75th percentile of performance as compared to the office REITs in the NAREIT index.

On March 24, 2020, the Company granted LTIP awards to senior management of the Company, including the General Partner’s executive officers (the “2020 LTIP Awards”). All of the 2020 LTIP Awards were in the form of LTIP Units and constitute awards under the 2013 Plan. All of the target 2020 LTIP Awards were in the form of performance-based LTIP Units under the Company’s Outperformance Plan (the “2020 OPP”) adopted by the General Partner’s Board of Directors, consisting of a multi-year, performance-based equity compensation plan and related forms of award agreement (the “2020 PBV LTIP Units”).

The 2020 OPP was designed to align the interests of senior management to relative and absolute performance of the Company over a three year performance period from March 24, 2020 through March 23, 2023. Participants of performance-based awards in the 2020 OPP will only earn the full awards if, over the three year performance period, the Company achieves a thirty-six percent (36%) absolute total stockholder return (“TSR”) and if the Company’s TSR is in the 75th percentile of performance as compared to the REITs in the NAREIT index.

On January 4, 2021, in accordance with Mr. Cardoso’s employment agreement, the Company granted LTIP awards (the “J Series 2021 LTIP Awards”). All of the J Series 2021 LTIP Awards were in the form of LTIP Units and constitute awards under the 2013 Plan. All

of the target 2021 LTIP Awards were in the form of performance-based LTIP Units under the Company’s Outperformance Plan (the “J Series 2021 OPP”) adopted by the General Partner’s Board of Directors, consisting of a multi-year, performance-based equity compensation plan and related forms of award agreement (the “J Series 2021 PBV LTIP Units”).

The J Series 2021 OPP was subject to the achievement of certain sales performance milestones with respect to commercial asset dispositions by the Company over a performance period from August 1, 2020 through December 31, 2022. These sales milestones will be based on the aggregate gross sales prices of the assets, provided that the asset will only be included in the milestone if it is sold for not less than 85% of its estimated net asset value, as defined in the agreement.

On April 21, 2021, the Company granted long-term incentive plan awards to senior management of the Company, including the General Partner’s executive officers (the “2021 RSU LTIP Awards”). All of the 2021 RSU LTIP Awards were in the form of restricted stock units (each, an “RSU”) and constitute awards under the 2013 Plan. Each RSU entitles the holder to one share of the General Partner’s common stock upon settlement. 291,951 of the RSUs are subject to time-based vesting conditions (the “TRSUs”) and will vest in three equal, annual installments over a three year period commencing on April 21, 2022. 452,730 of the RSUs are subject to performance based vesting conditions (the “PRSUs”). Recipients will only earn the full amount of the PRSUs if, over the three year performance period, the General Partner achieves a thirty-six percent (36%) absolute total stockholder return (“TSR”) and if the General Partner’s TSR is in the 75th percentile of performance as compared to a group of twenty-four (24) peer REITs.

Up to an additional 291,951 RSUs were granted subject to the achievement of certain outperformance conditions (the “OPRSUs”). Recipients will only earn the full amount of the OPRSUs of the General Partner achieves adjusted funds from operations of $0.60 per share in the fiscal year ending December 31, 2023. The OPRSUs were granted subject to and may not be earned, vested or settled until stockholder approval of an increase in the shares available under the 2013 plan at the Company’s 2021 annual meeting of stockholders to be held on June 9, 2021.  If shareholder approval is not obtained at the annual meeting, then all of the OPRSUs shall be canceled and forfeited.

The 2021 RSU LTIP Awards are designed to align the interests of senior management to relative and absolute performance of the Company over a three year performance period from April 21, 2021 through April 20, 2024. RSUs will remain subject to forfeiture depending on the extent that the 2021 RSU LTIP Awards vest.

LTIP Units will remain subject to forfeiture depending on the extent that the 2018 LTIP Awards, 2019 LTIP Awards, 2020 LTIP Awards vest and J Series 2021 LTIP Awards. The number of LTIP Units to be issued initially to recipients of the 2018 PBV LTIP Awards, 2019 PBV LTIP Awards, 2020 PBV LTIP Awards and J Series LTIP Awards is the maximum number of LTIP Units that may be earned under the awards. The number of LTIP Units that actually vest for each award recipient will be determined at the end of the performance measurement period. For the 2018 LTIP Awards, 2019 LTIP Awards and 2020 LTIP Awards, TSR for the Company and for the Index over the three year measurement period and other circumstances will determine how many LTIP Units vest for each recipient; if they are fewer than the number issued initially, the balance will be forfeited as of the performance measurement date. For the J Series LTIP Awards, achievement of the sales performance milestone will determine how many LTIP Units vest for Mr. Cardoso, and if the amount vested is fewer than the number issued, the balance will be forfeited as of the end of the Measurement Period.

Prior to vesting, recipients of LTIP Units will be entitled to receive per unit distributions equal to one-tenth (10 percent) of the regular quarterly distributions payable on a Common Unit but will not be entitled to receive any special distributions. Distributions with respect to the other nine-tenths (90 percent) of regular quarterly distributions payable on a common unit will accrue but shall only become payable upon vesting of the LTIP Unit. After vesting of the 2018 TBV LTIP Units, 2019 TBV LTIP Units and 2020 TBV LTIP Units or the end of the measurement period for the 2018 PBV LTIP Units, 2019 PBV LTIP Units, 2020 PBV LTIP Units and J Series 2021 PBV LTIP Units, the number of LTIP Units, both vested and unvested, will be entitled to receive distributions in an amount per unit equal to distributions, both regular and special, payable on a Common Unit.

As of March 31, 2021, the Company had $10.2 million of total unrecognized compensation cost related to unvested LTIP awards granted under the Company’s stock compensation plans. That cost is expected to be recognized over a weighted average period of 2.1 years.

DEFERRED STOCK COMPENSATION PLAN FOR DIRECTORS

The Amended and Restated Deferred Compensation Plan for Directors, which commenced January 1, 1999, allows non-employee directors of the Company to elect to defer up to 100 percent of their annual retainer fee into deferred stock units. The deferred stock units are convertible into an equal number of shares of common stock upon the directors’ termination of service from the Board of Directors or a change in control of the Company, as defined in the plan. Pursuant to the termination of service of five directors from the Board of Directors on June 12, 2019, the Company converted 193,949 deferred stock units into shares of common stock. Pursuant to the termination of service of two directors from the Board of Directors on June 12, 2020, the Company converted 61,277 deferred stock units into shares of common stock. Deferred stock units are credited to each director quarterly using the closing price of the Company’s common stock on the applicable dividend record date for the respective quarter. Each participating director’s account is

also credited for an equivalent amount of deferred stock units based on the dividend rate for each quarter.

During the three months ended March 31, 2021 and 2020, 4,583 and 5,804 deferred stock units were earned, respectively. As of March 31, 2021 and December 31, 2020, there were 24,278 and 17,854 deferred stock units outstanding, respectively.

EARNINGS PER SHARE/UNIT

Basic EPS or EPU excludes dilution and is computed by dividing net income available to common shareholders or unitholders by the weighted average number of shares or units outstanding for the period. Diluted EPS or EPU reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock. In the calculation of basic and diluted EPS and EPU, a redemption value adjustment of redeemable noncontrolling interests attributable to common shareholders or unitholders is included in the calculation to arrive at the numerator of net income (loss) available to common shareholders or unitholders.

The following information presents the Company’s results for the three months ended March 31, 2021 and 2020 in accordance with ASC 260, Earnings Per Share (dollars in thousands, except per share amounts):
