Share-based Payment Arrangement [Abstract] |
Stock Option and Incentive Plan | 12. Stock Option and Incentive Plan On February 1, 2022, BXP’s Compensation Committee approved the 2022 MYLTIP awards under the Boston Properties, Inc. 2021 Stock Option and Incentive Plan (the “2021 Plan”) to certain officers and employees of BXP. The 2022 MYLTIP awards consist of two, equally weighted (50% each) components that utilize BXP’s TSR over a three-year measurement period as the performance metric. The first component of the 2022 MYLTIP represents one-half (50%) of the target grant-date value of the award. The number of LTIP Units that can be earned under this component ranges from zero to 200% of the target number of LTIP Units, based on BXP’s three-year, annualized relative TSR performance compared to a custom index of peer companies. Under this component, 100% of the target number of LTIP Units will be earned if BXP’s TSR equals the custom index TSR; for relative TSR performance between -1,000 basis points and +1,000 basis points, the number of LTIP Units earned will be determined using linear interpolation. The second component represents the remaining one-half (50%) of the target grant-date value of the 2022 MYLTIP. The number of LTIP Units that can be earned under this component ranges from zero to 200% of the target number of LTIP Units, based on BXP’s non-annualized, cumulative absolute TSR during the three-year performance period. Under this component, 100% of the target number of LTIP Units will be earned if BXP achieves an absolute TSR equal to +1,000 basis points; if BXP’s absolute TSR is greater than -4,000 basis points but less than +6,000 basis points, then the number of LTIP Units earned will be determined using linear interpolation. Total earned awards under the 2022 MYLTIP, if any, will equal the sum of the number of LTIP Units earned under the first and second components and will range from zero to a maximum of 254,061 LTIP Units with a target of approximately 127,031 LTIP Units and linear interpolation between zero and maximum. Earned awards (if any) will vest 100% on January 31, 2025, but may not be converted, redeemed, sold or otherwise transferred for one additional year thereafter. Vesting will be accelerated in the event of a change in control, termination of employment by BXP without cause, or termination of employment by the award recipient for good reason, death, disability or retirement. If there is a change of control prior to January 31, 2025, earned awards will be calculated based on TSR performance up to the date of the change of control. The 2022 MYLTIP awards are in the form of LTIP Units issued on the grant date, and they are subject to forfeiture to the extent awards are not earned. Prior to the performance measurement date holders of the 2022 MYLTIP Units are only entitled to one-tenth (10%) of the regular quarterly distributions payable on common partnership units. Following the completion of the three-year performance period, the Company will also make a “catch-up” cash payment on the 2022 MYLTIP Units that are ultimately earned in an amount equal to the regular and special distributions, if any, declared during the performance period on BXP’s Common Stock, less the distributions actually paid to holders of 2022 MYLTIP Units during the performance period on all of the awarded 2022 MYLTIP Units. Under ASC 718 “Compensation - Stock Compensation,” the 2022 MYLTIP awards have an aggregate value of approximately $17.3 million, which amount will generally be amortized into earnings under the graded vesting method. On February 4, 2022, the measurement period for the Company’s 2019 MYLTIP awards ended and, based on BXP’s relative TSR performance, the final payout was determined to be 69.0% of target, or an aggregate of approximately $8.6 million (after giving effect to employee separations). As a result, an aggregate of 144,043 2019 MYLTIP Units that had been previously granted were automatically forfeited. During the six months ended June 30, 2022, BXP issued 37,871 shares of restricted common stock and BPLP issued 261,421 LTIP Units and 254,061 2022 MYLTIP Units to employees and non-employee directors under the 2021 Plan. Employees and non-employee directors paid $0.01 per share of restricted common stock and $0.25 per LTIP Unit and 2022 MYLTIP Unit. When issued, LTIP Units are not economically equivalent in value to a share of Common Stock, but over time can increase in value to one-for-one parity with Common Stock if there is sufficient appreciation in the value of the Company’s assets. The aggregate value of the LTIP Units is included in noncontrolling interests in the Consolidated Balance Sheets of BXP and BPLP. A substantial majority of the grants of restricted common stock and LTIP Units to employees vest in four equal annual installments. Restricted common stock is measured at fair value on the date of grant based on the number of shares granted and the closing price of BXP’s Common Stock on the date of grant as quoted on the New York Stock Exchange. Such value is recognized as an expense ratably over the corresponding employee service period. The shares of restricted common stock granted during the six months ended June 30, 2022 were valued at approximately $4.3 million ($113.58 per share weighted-average). The LTIP Units granted were valued at approximately $28.2 million (approximately $108.02 per unit weighted-average fair value) using a Monte Carlo simulation method model. The per unit fair values of the LTIP Units granted were estimated on the dates of grant and for a substantial majority of such units were valued using the following assumptions: an expected life of 5.7 years, a risk-free interest rate of 1.71% and an expected price volatility of 31.0%. Because the 2012 OPP Units and 2013 - 2022 MYLTIP Units are subject to both a service condition and a market condition, the Company recognizes the related compensation expense under the graded vesting attribution method. Under the graded vesting attribution method, each portion of the award that vests at a different date is accounted for as a separate award and recognized over the period appropriate to that portion so that the compensation cost for each portion should be recognized in full by the time that portion vests. The Company recognizes forfeitures as they occur on its awards of stock-based compensation. Dividends paid on both vested and unvested shares of restricted stock are charged directly to Dividends in Excess of Earnings in Boston Properties, Inc.’s Consolidated Balance Sheets and Partners’ Capital in Boston Properties Limited Partnership’s Consolidated Balance Sheets. Aggregate stock-based compensation expense associated with restricted stock, LTIP Units and MYLTIP Units was approximately $14.6 million and $14.0 million for the three months ended June 30, 2022 and 2021, respectively, and $35.5 million and $33.8 million for the six months ended June 30, 2022 and 2021, respectively. At June 30, 2022, there was (1) an aggregate of approximately $29.5 million of unrecognized compensation expense related to unvested restricted stock, LTIP Units and 2019 MYLTIP Units and (2) an aggregate of approximately $9.6 million of unrecognized compensation expense related to unvested 2020 - 2022 MYLTIP Units that is expected to be recognized over a weighted-average period of approximately 2.1 years.
