SHARE-BASED COMPENSATION PLANS |
SHARE-BASED COMPENSATION PLANS | 15. SHARE-BASED COMPENSATION PLANS On June 1, 2016 the Company’s shareholders approved an amendment and restatement of the Company’s 2007 Equity Incentive Plan, a share-based employee compensation plan originally approved by shareholders on May 8, 2007 and subsequently amended with shareholder approval on June 2, 2010 (as amended and restated, the “2007 Plan”). The purpose of the 2007 Plan is to attract and retain highly qualified executive officers, Trustees and key employees and other persons and to motivate such officers, Trustees, key employees, and other persons to serve the Company and its affiliates to expend maximum effort to improve the business results and earnings of the Company, by providing to such persons an opportunity to acquire or increase a direct proprietary interest in the operations and future success of the Company. To this end, the 2007 Plan provides for the grant of share options, share appreciation rights, restricted shares, restricted share units, performance awards, which may be denominated in cash or shares, included restricted shares and restricted share units, and other share-based awards, including unrestricted common shares or awards denominated or payable in, or valued in whole or part by reference to, common shares. Any of these awards may, but need not, be made as performance incentives to reward attainment of annual or long-term performance goals. Share options granted under the 2007 Plan may be non-qualified share options or incentive share options. Upon shareholder approval of the amendment and restatement of the 2007 Plan in June 2016, 4,500,000 additional common shares were made available for award under the 2007 Plan. As a result, these 4,500,000 additional shares, together with the 991,117 shares that remained available for future awards under the 2007 Plan at the time of the shareholder approval, plus any common shares that are restored to availability upon expiration or forfeiture of outstanding options or restricted share awards, would constitute the “Aggregate Share Reserve”. As of December 31, 2017: (i) 4,936,124 common shares remained available for future awards under the 2007 Plan; (ii) 465,045 unvested restricted share awards were outstanding under the 2007 Plan; and (iii) 1,833,173 common shares were subject to outstanding options under the 2007 Plan (with the outstanding options having a weighted average exercise price of $16.55 per share and a weighted average term to maturity of 5.26 years). Prior to the June 2016 amendments, the 2007 Plan used a “Fungible Units” methodology for computing the maximum number of common shares available for issuance under the 2007 Plan. The Fungible Units methodology assigned weighted values to different types of awards under the 2007 Plan without assigning specific numerical limits for different types of awards. As amended in June 2016, the 2007 Plan provides that any common shares made the subject of awards under the 2007 Plan will count against the Aggregate Share Reserve as one (1) unit. The Aggregate Share Reserve and the computation of the number of common shares available for issuance is subject to adjustment upon certain corporate transactions or events, including share splits, reverse share splits and recapitalizations. The number of shares counted against the Aggregate Share Reserve includes the full number of shares subject to the award, and is not reduced in the event shares are withheld to fund withholding tax obligations, or, in the case of options and share appreciation rights, where shares are applied to pay the exercise price. If an option or other award granted under the 2007 Plan expires, is forfeited or otherwise terminates, the common shares subject to any portion of the award that expires, is forfeited or that otherwise terminates, as the case may be, again becomes available for issuance under the 2007 Plan. The 2007 Plan is administered by the Compensation Committee of the Company’s Board of Trustees (the “Compensation Committee”), which is appointed by the Board of Trustees. The Compensation Committee interprets the 2007 Plan and, subject to its right to delegate authority to grant awards, determines the terms and provisions of option grants and share awards. Subject to adjustment upon certain corporate transactions or events, a participant (other than a non-employee trustee) may not receive awards under the 2007 Plan in any one calendar year covering more than 1,000,000 shares. Subject to adjustment upon certain corporate transactions or events, a non-employee trustee may not receive awards under the 2007 Plan in any one calendar year covering more than 250,000 shares. Under the 2007 Plan, the Compensation Committee determines the vesting schedule of each share award and option, subject to a one-year minimum vesting requirement, but with permitted acceleration of vesting in the event of a participant’s death or disability, or in the event of a change in control or certain changes in our capital structure. Notwithstanding the foregoing one-year minimum vesting limitation, up to five percent of the shares subject to the Aggregate Share Reserve may be subject to awards that are not subject to such limitation. The exercise price for options is equivalent to the fair value of the underlying common shares at the grant date. The Compensation Committee also determines the term of each option, which shall not exceed 10 years from the grant date. On October 19, 2004, the Company’s sole shareholder approved a share-based employee compensation plan, the 2004 Equity Incentive Plan (the “2004 Plan”). The 2004 Plan expired in October 2014. Prior to its expiration, a total of 3.0 million common shares were reserved for issuance under the 2004 Plan. Subsequent to its expiration, no new equity awards may be granted under the 2004 Plan, and to the extent that options expire unexercised or are terminated, surrendered or canceled, the options and share awards no longer become available for future grants under the 2004 Plan. As of December 31, 2017, there were approximately five thousand shares outstanding under the 2004 Plan. Share Options The fair values for options granted in 2017, 2016, and 2015 were estimated at the time the options were granted using the Black-Scholes option-pricing model applying the following weighted average assumptions:
Assumptions: |  | 2017 |  | 2016 |  | 2015 |
Risk-free interest rate |  |  | 2.2 | % |  | 1.8 | % |  | 1.5 | %
Expected dividend yield |  |  | 3.5 | % |  | 2.7 | % |  | 2.6 | %
Volatility (1) |  |  | 33.00 | % |  | 33.00 | % |  | 33.00 | %
Weighted average expected life of the options (2) |  |  | 6.0 | years |  | 6.0 | years |  | 6.0 | years
Weighted average grant date fair value of options granted per share |  | $ | 6.12 |  | $ | 7.61 |  | $ | 6.23 |
| (1) |  | Expected volatility is based upon the level of volatility historically experienced.
| (2) |  | Expected life is based upon our expectations of share option recipients’ expected exercise and termination patterns.
The Black-Scholes option-pricing model was developed for use in estimating the fair value of traded options. In addition, option-pricing models require the input of highly subjective assumptions, including the expected share price volatility. Volatility for the 2017, 2016 and 2015 grants was based on the trading history of the Company’s shares. In 2017, 2016, and 2015, the Company recognized compensation expense related to options issued to employees and executives of approximately $1.5 million, $1.3 million and $1.0 million, respectively, which is included in General and administrative expense on the Company’s consolidated statements of operations. During 2017, 289,104 share options were issued for which the fair value of the options at their respective grant dates was approximately $1.8 million. The share options vest over three years. As of December 31, 2017, the Company had approximately $1.8 million of unrecognized option compensation cost related to all grants that will be recorded over the next three years. The table below summarizes the option activity under the 2004 Plan and the 2007 Plan for the years ended December 31, 2017, 2016 and 2015:

As of December 31, 2017, the aggregate intrinsic value of options outstanding, of options that vested or expected to vest, and of options that were exercisable was approximately $35.3 million. The aggregate intrinsic value of options exercised was approximately $8.8 million for the year ended December 31, 2017. Restricted Shares The Company applies the fair value method of accounting for contingently issued shares. As such, each grant is recognized ratably over the related vesting period. Approximately 166,000 restricted shares and share units were issued during 2017 for which the fair value of the restricted shares and share units at their respective grant dates was approximately $4.7 million, which vest over three to five years. During 2016, approximately 155,000 restricted shares and share units were issued for which the fair value of the restricted shares and share units at their respective grant dates was approximately $5.2 million. As of December 31, 2017 the Company had approximately $5.2 million of remaining unrecognized restricted share and share unit compensation costs that will be recognized over the next five years. Restricted share awards are considered to be performance awards and are valued using the share price on the grant date. The compensation expense recognized related to these awards and remaining unrecognized compensation costs are included in the amounts disclosed above. In 2017, 2016 and 2015, the Company recognized compensation expense related to restricted shares and share units issued to employees and Trustees of approximately $4.1 million, $3.6 million, and $2.7 million, respectively; these amounts were recorded in general and administrative expense.
