[1] For 2023, 2024, and 2025 the CEO was David H. Lesser (Current CEO) and the sole Non-CEO NEO was Susan Hollander.
[2] Compensation actually paid (“CAP”) was determined by making the following adjustments for equity awards for 2023, 2024, and 2025. The fair value of stock options was estimated using the Black-Scholes option-pricing model. For the 2025 measurement date, the assumptions used were: expected volatility of 81.3% (based on the Trust’s historical share price volatility over a period approximating the awards’ remaining expected term), risk-free interest rate of 4.1% (based on the U.S. Treasury yield curve for a maturity approximating the awards’ remaining term), and expected dividend yield of 0% (the Trust has not paid dividends on its common shares since 2013).
[3] Cumulative TSR is calculated by dividing the sum of the cumulative amount of dividends for the measurement period, assuming dividend reinvestment, and the difference between the Trust’s share price at the end and the beginning of the measurement period by the Trust’s share price at the beginning of the measurement period. The Trust has not paid dividends since 2013.
