Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
SHARE-BASED COMPENSATION	SHARE-BASED COMPENSATION Share-based awards are provided to officers, non-officer employees, and trustees under our 2015 Incentive Plan approved by shareholders on September 15, 2015, which allows for awards in the form of cash, unrestricted and restricted common shares, and restricted stock units ("RSUs") up to an aggregate of 425,000 shares over the ten-year period in which the plan is in effect. Under our 2015 Incentive Plan, officers and non-officer employees may earn share awards under a long-term incentive plan, which is a forward-looking program that measures long-term performance over the stated performance period. These awards are payable to the extent deemed earned in shares. The terms of the long-term incentive awards granted under the revised program may vary from year to year. 2019 LTIP Awards Awards granted to officers on March 8, 2019, consist of time-based RSU awards for 6,391 shares and performance-based RSU awards based on relative total shareholder return (“TSR”), for 12,781 shares. All of these awards are classified as equity awards. The time-based RSU awards vest as to one-third of the shares on each of March 8, 2020, March 8, 2021, and March 8, 2022. Awards granted on June 15, 2019, consist of 169 time-based RSUs that vest on June 15, 2020. Awards granted on August 10, 2019, consist of 100 time-based RSUs that vest on August 10, 2020. Awards granted on August 29, 2019, consist of 444 time-based RSUs that vest as to one-third on each of August 29, 2020, August 29, 2021, and August 29, 2022; 98 time-based RSUs that vest as to one-third on March 8, 2020, March 8, 2021, and March 8, 2022; and 197 performance RSUs based on TSR. The performance-based RSU awards are earned based on our TSR as compared to the MSCI U.S. REIT Index over a forward-looking three-year period. The maximum number of RSUs eligible to be earned under this performance-based award is 25,562 RSUs, which is 200% of the RSUs granted. Earned awards (if any) will fully vest as of the last day of the measurement period. These awards have market conditions in addition to service conditions that must be met for the awards to vest. We recognize compensation expense ratably based on the grant date fair value, as determined using the Monte Carlo valuation model, regardless of whether the market conditions are achieved and the awards ultimately vest. Therefore, previously recorded compensation expense is not adjusted in the event that the market conditions are not achieved. We based the expected volatility on the historical volatility of our daily closing share price, the risk-free interest rate on the interest rates on U.S. treasury bonds with a maturity equal to the remaining performance period of the award, and the expected term on the performance period of the award. The assumptions used to value the performance RSU awards were an expected volatility of 25.5%, a risk-free interest rate of 2.43%, and an expected life of 2.82 years. The share price at the grant date, March 8, 2019, was $58.06 per share. Awards granted to trustees on May 17, 2019, consist of 812 RSUs which vested immediately and awards granted on June 13, 2019 consist of 7,521 time-based RSU awards which vest on June 13, 2020. All of these awards are classified as equity awards. Share-Based Compensation Expense Share-based compensation expense recognized in the consolidated financial statements for all outstanding share-based awards was $1.5 million and $1.0 million for the nine months ended September 30, 2019 and 2018, respectively. The increase in expense was primarily due to the timing of award grants in connection with the change in our fiscal year end, additional officers included in award grants, and a decrease in forfeitures in the current period compared to the prior period.
