Share-Based Compensation

6 Months Ended

Jun. 30, 2021

Share-based Payment Arrangement, Noncash Expense [Abstract]

As of June 30, 2021, we had two share-based compensation plans: the Sun Communities, Inc. 2015 Equity Incentive Plan ("2015 Equity Incentive Plan") and the First Amended and Restated 2004 Non-Employee Director Option Plan ("2004 Non-Employee Director Option Plan"). We believe granting equity awards will provide certain executives, key employees and directors additional incentives to promote our financial success and promote employee and director retention by providing an opportunity to acquire or increase the direct proprietary interest of those individuals in our operations and future.

During the six months ended June 30, 2021 and 2020, shares were granted as follows:

We estimate the fair value of share-based compensation for restricted stock with market conditions using a Monte Carlo simulation. At the grant date our common stock price was $151.89. Based on the Monte Carlo simulation we expect 62.1 percent of the 81,000 shares to vest.
