Share-Based Compensation

Stockholder Approved Equity Compensation Plans

As of September 30, 2015, we maintained one share-based incentive compensation plan, the Kilroy Realty 2006 Incentive Award Plan, as amended (the “2006 Plan”). As of September 30, 2015, 1,724,324 shares were available for grant under the 2006 Plan. The calculation of shares available for grant includes a reserve for a sufficient number of shares to cover the vesting and payment of performance-based vesting awards at the target levels for either performance and/or market conditions with outstanding performance periods. At our Annual Meeting of Stockholders held on May 21, 2015, stockholders approved an amendment and restatement of the 2006 Plan, which included an increase in the share limit to 8,320,000 shares.

2015 Share-Based Compensation Grants

On January 27, 2015, the Executive Compensation Committee of the Company’s Board of Directors awarded 212,468 restricted stock units (“RSUs”) to certain officers of the Company under the 2006 Plan, which included 127,657 RSUs (at the target level of performance), or 60%, that are subject to market and performance-based vesting requirements (the “2015 Performance-Based RSUs”) and 84,811 RSUs, or 40%, that are subject to time-based vesting requirements (the “2015 Time-Based RSUs”).

2015 Performance-Based RSU Grant

The 2015 Performance-Based RSUs are scheduled to vest at the end of a three-year period based upon the achievement of pre-set FFO per share goals (the “performance condition”) for the year ending December 31, 2015 and also based upon the average annual relative total stockholder return ranking for the Company compared to an established comparison group of companies (the “market condition”) for the three-year period ending December 31, 2017. The 2015 Performance-Based RSUs are also subject to a three-year service vesting provision and are scheduled to cliff vest at the end of the three-year period. The number of 2015 Performance-Based RSUs ultimately earned could fluctuate from the target number of 2015 Performance-Based RSUs granted based upon the levels of achievement for both the performance condition and the market condition. The estimate of the number of 2015 Performance-Based RSUs earned are evaluated quarterly during the 2015 performance period based on our estimate as to the 2015 FFO per share performance measured against the applicable goals. As of September 30, 2015, 168,788 2015 Performance-Based RSUs are estimated to be earned based on the Company’s estimate of 2015 FFO per share performance measured against the applicable goals, and the compensation cost recorded to date for this program was based on that revised estimate. Compensation expense for the 2015 Performance-Based RSU grant will be recorded on a straight-line basis over the three-year period.

Each 2015 Performance-Based RSU represents the right to receive one share of our common stock in the future. The total fair value of the 2015 Performance-Based RSU grant was $10.1 million at January 27, 2015 and was calculated using a Monte Carlo simulation pricing model based on the assumptions in the table below. The determination of the fair value of the 2015 Performance-Based RSU grant takes into consideration the likelihood of achievement of both the performance condition and the market condition discussed above. For the nine months ended September 30, 2015, we recorded compensation expense based upon the $78.55 fair value at January 27, 2015. The following table summarizes the assumptions utilized in the Monte Carlo simulation pricing model:



	Fair Value Assumptions
Fair value per share at January 27, 2015	$78.55
Expected share price volatility	20.00%
Risk-free interest rate	0.92%
Remaining expected life	2.9 years

The computation of expected volatility is based on a blend of the historical volatility of our shares of common stock over approximately six years, as that is expected to be most consistent with future volatility and equates to a time period twice as long as the approximate three-year remaining performance period of the RSUs and implied volatility data based on the observed pricing of six month publicly-traded options on our shares of common stock. The risk-free interest rate is based on the yield curve on zero-coupon U.S. Treasury STRIP securities in effect at January 27, 2015. The expected dividend yield is estimated by examining the average of the historical dividend yield levels over the remaining 2.9 year term of the RSUs and our current annualized dividend yield as of January 27, 2015. The expected life of the RSUs is equal to the remaining 2.9 year vesting period at January 27, 2015.

2015 Time-Based RSU Grant

The 2015 Time-Based RSUs are scheduled to vest in three equal installments beginning on January 5, 2016 through January 5, 2018. Compensation expense for the 2015 Time-Based RSUs will be recognized on a straight-line basis over the three-year service vesting period. Each 2015 Time-Based RSU represents the right to receive one share of our common stock in the future. The total fair value of the 2015 Time-Based RSU grant was $6.4 million, which was based on the $75.34 closing share price of the Company’s common stock on the NYSE on January 27, 2015.

Share-Based Award Activity

During the nine months ended September 30, 2015, 265,000 non-qualified stock options were exercised and issued at an exercise price per share equal to $42.61. As of September 30, 2015, we had 687,000 stock options outstanding.

Share-Based Compensation Cost Recorded During the Period

The total compensation cost for all share-based compensation programs was $4.3 million and $4.0 million for the three months ended September 30, 2015 and 2014, respectively, and $13.6 million and $10.3 million for the nine months ended September 30, 2015 and 2014, respectively. Of the total share-based compensation costs, $0.7 million and $0.6 million was capitalized as part of real estate assets for the three months ended September 30, 2015 and 2014, respectively, and $2.3 million and $1.5 million was capitalized as part of real estate assets for the nine months ended September 30, 2015 and 2014, respectively. As of September 30, 2015, there was approximately $35.2 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 September 30, 2015.
