Share-Based Compensation

Stockholder Approved Equity Compensation Plans

As of September 30, 2014, we maintained one share-based incentive compensation plan, the Kilroy Realty 2006 Incentive Award Plan as amended (the “2006 Plan”). As of March 31, 2014, no shares were available for grant under the 2006 Plan. At our Annual Meeting of Stockholders, on May 22, 2014, stockholders approved an amendment of the 2006 Plan, which included an increase in the share limit to 7,120,000 shares. As of September 30, 2014, 728,865 shares were available for grant under the amended 2006 Plan.

2014 Share-Based Compensation Grants

On January 29, 2014, the Executive Compensation Committee of the Company’s Board of Directors awarded to certain officers of the Company under the 2006 Plan of 236,604 restricted stock units (“RSUs”), 119,098 RSUs that are subject to market and performance-based vesting requirements (the “2014 Performance-Based RSU Grant”) and 117,506 RSUs that are subject to time-based vesting requirements (the “2014 Time-Based RSU Grant”). As of the RSU grant date, an insufficient number of shares were available under the 2006 Plan to settle these RSUs in stock and the RSUs were subject to liability accounting. As discussed above, on May 22, 2014 we received stockholder approval for an increase to our share limit which resulted in a sufficient number of shares authorized by our stockholders for issuance under the 2006 Plan to cover settlement of these awards. As a result, as of May 22, 2014 given we have the ability to deliver shares to settle the RSUs, we reclassified these awards as equity awards and re-measured the fair value of the awards as of that date.

2014 Performance-Based RSU Grant

The 2014 Performance-Based RSUs are scheduled to vest at the end of a three year period based upon the achievement of pre-established levels of FFO per share (the “performance condition”) for the year ended December 31, 2014 and also based upon the average annual relative total stockholder return targets (the “market condition”) for the three year period ending December 31, 2016. The 2014 Performance-Based RSUs are also subject to a three-year service vesting provision and will cliff vest at the end of the three-year period. The number of 2014 Performance-Based RSUs ultimately earned, and therefore the compensation costs for these awards, could fluctuate from the 119,098 RSUs granted based upon the levels of achievement for both the FFO and relative stockholder return metrics. During the 2014 performance period, the estimate of the number of awards earned were evaluated quarterly based on our forecasted level of achievement of the FFO hurdle. Compensation expense for the 2014 Performance-Based RSU Grant will be recorded on a straight-line basis over the three year period.

Each 2014 Performance-Based RSU represents the right to receive one share of our common stock in the future. As of March 31, 2014, we recorded compensation expense for the award based upon the fair value at period end of $63.44, as we had an insufficient number of shares available for issuance under the 2006 Plan at that time. As discussed above, upon stockholder approval of the amended 2006 Plan on May 22, 2014, we were required to re-measure the fair value of the 2014 Performance-Based RSU Grant and record compensation expense based on the fair value at that date for the cumulative portion of the performance period that had elapsed. The total fair value of the 2014 Performance-Based RSU Grant was $7.7 million at May 22, 2014 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 2014 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, 2014, we recorded compensation expense based upon the $65.03 fair value at May 22, 2014. The following table summarizes the assumptions utilized in the Monte Carlo simulation pricing model:



	Fair Value Assumptions
Fair value per share at May 22, 2014	$65.03
Expected share price volatility	24.00%
Risk-free interest rate	0.61%
Remaining expected life	2.6

The computation of expected volatility is based on a blend of the historical volatility of our shares of common stock over approximately five years as that is expected to be most consistent with future volatility and equates to a time period twice as long as the approximate two and a half 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 May 22, 2014. The expected dividend yield is estimated by examining

the average of the historical dividend yield levels over the remaining 2.6 year term of the RSUs and our current annualized dividend yield as of May 22, 2014. The expected life of the RSUs is equal to the remaining 2.6 year vesting period at May 22, 2014.

2014 Time-Based RSU Grant

The 2014 Time-Based RSUs are scheduled to vest in four equal installments beginning on January 5, 2015 through January 5, 2018. Compensation expense for the 2014 Time-Based RSUs will be recognized on a straight-line basis over the four year service vesting period. Each 2014 Time-Based RSUs represents the right to receive one share of our common stock in the future. As of March 31, 2014, we recorded compensation expense for the award based upon the fair value at period end of $51.64, because at that time an insufficient number of shares were available for issuance under the 2006 Plan. As discussed above, upon stockholder approval of the amended 2006 Plan on May 22, 2014, we were required to re-measure the fair value of the 2014 Time-Based RSU Grant and record compensation expense based on the fair value at that date, for the cumulative portion of the performance period that had elapsed. The total fair value was $7.1 million, which was based on the $60.16 closing share price of the Company’s common stock on the NYSE on May 22, 2014.

Share-Based Award Activity

During the nine months ended September 30, 2014, 482,000 non-qualified stock options were exercised and issued at an exercise price per share equal to $42.61. The total shares exercised include 22,162 common shares that were tendered in accordance with the terms of the 2006 Plan to satisfy minimum statutory tax withholding requirements and exercise price related to the non-qualified stock options exercised. We accept the return of shares at the current quoted closing share price of the Company’s common stock to satisfy tax obligations and cover the exercise price.

Share-Based Compensation Cost Recorded During the Period

The total compensation cost for all share-based compensation programs was $4.0 million and $2.5 million for the three months ended September 30, 2014 and 2013, respectively, and $10.3 million and $7.2 million for the nine months ended September 30, 2014 and 2013, respectively. Of the total share-based compensation costs, $0.6 million and $0.2 million was capitalized as part of real estate assets for the three months ended September 30, 2014 and 2013, respectively, and $1.5 million and $0.6 million was capitalized as part of real estate assets for the nine months ended September 30, 2014 and 2013, respectively. As of September 30, 2014, there was approximately $34.4 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 2.8 years. The remaining compensation cost related to these nonvested incentive awards had been recognized in periods prior to September 30, 2014.
