The 2017 Director Plan provides that a maximum of 450,000 shares of our common stock may be issued, and as of March 31, 2018, 390,154 shares of common stock remain available for future issuance. For the three months ended March 31, 2018 and 2017, we recognized $4 million and $3 million, respectively, of share-based compensation expense. As of March 31, 2018, unrecognized compensation expense was $27 million, which is expected to be recognized over a weighted-average period of 1.8 years.

Performance Stock Units (“PSUs”) generally vest at the end of a two or three-year performance period and are subject to the achievement of a market condition based on a measure of our total shareholder return relative to the total shareholder return of the companies that comprise the FTSE NAREIT Lodging Resorts Index (that have a market capitalization in excess of $1 billion as of the first day of the applicable performance period). The number of PSUs that may become vested ranges from zero to 200% of the number of PSUs granted to an employee, based on the level of achievement of the foregoing performance measure.

The grant date fair values of these awards were determined using a Monte Carlo simulation valuation model with the following assumptions:

Expected volatility⁽¹⁾		24.0	%
Dividend yield⁽²⁾		—
Risk-free rate		2.4	%
Expected term	2-3 years

⁽¹⁾	Due to limited trading history of our common stock, we used the historical and implied volatilities of our peer group in addition to our historical and implied volatilities over the performance period to estimate appropriate expected volatilities.

⁽²⁾	Dividends are assumed to be reinvested in shares of our common stock and dividends will not be paid unless shares vest.
