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 RSUs up to an aggregate of 4,250,000 shares, over the ten-year period in which the plan will be in effect. Under our 2015 Incentive Plan, officers and non-officer employees may earn share awards under a revised 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. Fiscal Year 2018 Executive LTIP Awards Awards granted on May 1, 2017, consist of 16,447 time-based restricted shares that vest as to one-third of the shares on each of May 1, 2018, May 1, 2019, and May 1, 2020. We recognize compensation expense associated with the time-based restricted share awards ratably over the requisite service periods. Awards granted on June 21, 2017, consist of time-based RSU awards, performance RSU awards based on leverage ratio, and performance RSU awards based on total shareholder return (“TSR”), each for 57,693 shares. All of these awards are classified as equity awards. The time-based RSUs vest as to one-third of the shares on each of June 21, 2018, May 1, 2019, and May 1, 2020. The maximum number of leverage ratio RSUs eligible to be earned is 115,386 RSUs. The TSR performance RSU awards are earned based on our TSR as compared to the MSCI US REIT Index over a forward looking three-year period. The maximum number of RSUs eligible to be earned is 115,386 RSUs. 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 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 27.3%, a risk-free interest rate of 1.48% and an expected life of 2.86 years. The share price at the grant date, June 21, 2017, was $6.15 per share. Total Compensation Expense Share-based compensation expense recognized in the consolidated financial statements for all outstanding share-based awards was $1.1 million and $1.4 million for the nine months ended January 31, 2018 and 2017, respectively.
