EXECUTIVE COMPENSATION HIGHLIGHTS

Philosophy and Objectives

Our executive officer compensation program supports our commitment to provide superior shareholder value. This program is designed to:

Attract, retain and reward executives who have the motivation, experience and skills necessary to lead us effectively and encourage them to make career commitments to us;

Base executive compensation levels on our overall financial and operational performance and the individual contribution of an executive officer to our success;

Create a link between the performance of our stock and executive compensation; and

Position executive compensation levels to be competitive with other similarly situated public companies, especially those in the real estate industry.

Elements of Compensation

The elements of 2024 executive compensation, as well as the compensation mix for our CEO, is shown below:

TimeRestricted Stock AwardEquity

The above performance restricted stock award, representing 15.1% of total executive compensation, is calculated based on the grant date fair value, which was measured using a Monte Carlo simulation in accordance with FASB ASC Topic 718.

The above time restricted stock award, representing 13.5% of total executive compensation, is calculated based on the grant date fair value in accordance with FASB ASC Topic 718.

The compensation mix for our CEO in the table above reflects a smaller percentage of equity pay compared to historical practice, as the Compensation Committee determined to award Mr. Shiffman only 5,000 shares in 2024 in light of the Company's performance. The 2024 award represented a significant decline compared to Mr. Shiffman's average award of 81,667 shares per year over the prior three years. In 2023, Mr. Shiffman's compensation mix included 91.8% of compensation in the form of equity, which is a more representative reflection of historical practice related to compensation mix for our CEO.
