Share-Based Compensation

3 Months Ended

Share-based Payment Arrangement [Abstract]

Stockholder Approved Share-Based Incentive Compensation Plan

As of March 31, 2022, we maintained one share-based incentive compensation plan, the Kilroy Realty 2006 Incentive Award Plan, as amended (the “2006 Plan”). The Company has a currently effective registration statement registering 10.7 million shares of our common stock for possible issuance under our 2006 Plan. As of March 31, 2022, approximately 1.0 million shares were available for grant under the 2006 Plan. The calculation of shares available for grant is presented after taking into account a reserve for a sufficient number of shares to cover the vesting and payment of 2006 Plan awards that were outstanding on that date, including performance-based vesting awards at (i) levels actually achieved for the performance conditions (as defined below) for which the performance period has been completed and (ii) at maximum levels for the other performance and market conditions (as defined below) for awards still in a performance period.

2022 Share-Based Compensation Grants

In January 2022, the Executive Compensation Committee of the Company’s Board of Directors awarded 351,281 restricted stock units (“RSUs”) to certain officers of the Company under the 2006 Plan, which included 193,111 RSUs (at the target level of performance) that are subject to market and/or performance-based vesting requirements (the “2022 Performance-Based RSUs”) and 158,170 RSUs that are subject to time-based vesting requirements (the “2022 Time-Based RSUs”).

2022 Performance-Based RSU Grant

The 2022 Performance-Based RSUs are scheduled to vest at the end of a three year period (consisting of calendar years 2022-2024). A target number of 2022 Performance-Based RSUs were awarded, and the final number of 2022 Performance-Based RSUs that vest (which may be more or less than the target number) will be based upon (1) during the first calendar year of the three year performance measurement period, the achievement of pre-set FFO per share goals that applies to 100% of the Performance-Based RSUs awarded (the “FFO Performance Condition”) and (2) a performance measure that applies to 50% of the award based upon a measure of the Company’s average debt to EBITDA ratio for the three year performance period (the “Debt to EBITDA Ratio Performance Condition”) and a market measure that applies to the other 50% of the award based upon the relative ranking of the Company’s total stockholder return for the three year performance period compared to the total stockholder returns of an established comparison group of companies over the same period (the “Market Condition”). The 2022 Performance-Based RSUs are also subject to a three year service vesting provision (the “service vesting condition”) and are scheduled to cliff vest on the date the final vesting percentage is determined following the end of the three year performance period under the awards. The number of 2022 Performance-Based RSUs ultimately earned could fluctuate from the target number of 2022 Performance-Based RSUs granted based upon the levels of achievement for the FFO Performance Condition, the Debt to EBITDA Ratio Performance Condition, the Market Condition, and the extent to which the service vesting condition is satisfied. The estimate of the number of 2022 Performance-Based RSUs earned is evaluated quarterly during the performance period based on our estimate for each of the performance conditions measured against the applicable goals. During the three months ended March 31, 2022, we recognized $1.1 million of compensation expense for the 2022 Performance-Based RSU grant. In the event we achieve a lower level of performance or fail to meet the FFO performance

condition, we would reverse a portion or all of the $1.1 million of compensation expense. Compensation expense for the 2022 Performance-Based RSU grant is recognized on a straight-line basis over the requisite service period for each participant, which is generally the three year service period, except for one participant whose compensation expense is recognized on an accelerated basis, due to clauses that render a portion of the vesting conditions to be non-substantive.

Each 2022 Performance-Based RSU represents the right to receive one share of our common stock in the future, subject to, and as modified by the Company’s level of achievement of the FFO Performance, the Debt to EBITDA Ratio Performance Condition and the Market Condition. The fair value of the award was calculated using a Monte Carlo simulation pricing model based on the assumptions in the table below, which resulted in the following grant date fair value per share.


			Fair Value Assumptions
Valuation date			January 28, 2022
Fair value on valuation date (in millions)			$12.7
Fair value per share on valuation date (1)			$67.62
Expected share price volatility			36.0%
Risk-free interest rate			1.35%

________________________

(1)For one participant, the fair value per share on the valuation date for their 2022 Performance-Based RSUs is $70.00.

The computation of expected volatility was based on a blend of the historical volatility of our shares of common stock over a period of twice the remaining performance period as of the grant date and implied volatility data based on the observed pricing of six month publicly-traded options on shares of our common stock. The risk-free interest rate was based on the yield curve on zero-coupon U.S. Treasury STRIP securities in effect at January 28, 2022.

For the three months ended March 31, 2022, we recorded compensation expense based upon the grant date fair value per share for each component multiplied by the estimated number of RSUs to be earned.

2022 Time-Based RSU Grant

The 2022 Time-Based RSUs are scheduled to vest in three equal annual installments beginning on January 5, 2023 through January 5, 2025. Compensation expense for the 2022 Time-Based RSUs is recognized on a straight-line basis over the requisite service period, which is generally the explicit service period except for one participant whose compensation expense is recognized on an accelerated basis, due to clauses that render a portion of the vesting conditions to be non-substantive. Each 2022 Time-Based RSU represents the right to receive one share of our common stock in the future, subject to continued employment through the applicable vesting date, unless accelerated upon separation of employment, provided certain conditions are met. The total grant date fair value of the 2022 Time-Based RSU awards was $10.0 million, which was based on the $63.05 closing share price of the Company’s common stock on the NYSE on the January 28, 2022 grant date.

2021 and 2020 Performance-Based RSUs

Compensation cost for the 2021 performance-based RSUs for the three months ended March 31, 2022 assumes the 2021 debt to EBITDA ratio performance condition is met at 100% of the target level of achievement for all participants. Compensation cost for the 2020 performance-based RSUs for the three months ended March 31, 2022 assumes the 2020 debt to EBITDA ratio performance condition is met at 150% of the target level of achievement (175.0% for one participant).

Share-Based Compensation Cost Recorded During the Period

The total compensation cost for all share-based compensation programs was $6.6 million and $9.6 million for the three months ended March 31, 2022 and 2021, respectively. Of the total share-based compensation costs, $1.3 million and $1.7 million was capitalized as part of the real estate assets for the three months ended March 31, 2022 and 2021, respectively. As of March 31, 2022, there was approximately $38.2 million of total unrecognized compensation cost related to nonvested incentive awards granted under share-based compensation arrangements that is expected to be recognized over a weighted-average period of 2.1 years. The remaining compensation cost related to these nonvested incentive awards had been recognized in periods prior to March 31, 2022.
