At March 31, 2016, the weighted average amortization period remaining for all of our equity awards was less than two years.

Restricted Stock

At March 31, 2016 and December 31, 2015, there were 223,914 and 187,180 shares, respectively, of restricted stock outstanding. Restrictions on these shares lapse through 2020. During the three months ended March 31, 2016, there were 144,056 shares of restricted stock granted, restrictions on 48,061 shares of restricted stock lapsed and those shares were distributed, and 59,261 shares of restricted stock awards forfeited.

Deferred Stock Units (“DSUs”)

At March 31, 2016 and December 31, 2015, there were 2,680,320 and 2,407,154 DSUs, respectively, outstanding of which 1,707,272 and 1,363,548, respectively, had vested. There were 281,014 DSUs granted, no DSUs distributed, and 7,849 DSUs forfeited during the three months ended March 31, 2016. Unvested DSUs at March 31, 2016 vest through 2020. During the three months ended March 31, 2016, equity compensation expense of $3 million was recognized in connection with the announced departures of two executives due to the full vesting of their DSUs in accordance with the terms of their employment agreements.

Performance Stock Units (“PSUs”)

At both March 31, 2016 and December 31, 2015, the target number of PSUs that were unvested was 656,549 and 849,021, respectively. PSUs do not vest until the third anniversary of their grant date, with the level of vesting at that time contingent on total stockholder return (defined as the change in our common stock price, adjusted to reflect the reinvestment of all dividends declared and/or paid on our common stock, relative to an average of the per share price of our common stock over a 40 trading day period preceding on the date of the PSU grant) over the three-year vesting period (“Three-Year TSR”). The number of underlying shares of our common stock that will vest during 2016 and in future years will vary between 0% (if Three-Year TSR is negative) and 200% (if Three-Year TSR is greater than or equal to 125%) of the target number of PSUs originally granted, adjusted upward (if vesting is greater than 0%) to reflect the value of dividends paid during the three-year vesting period.

During the three months ended March 31, 2016, equity compensation expense of $0.6 million was recognized in connection with the announced departures of two executives to reflect the pro-rated vesting of their PSUs through their expected departure dates in 2016 in accordance with the terms of their employment agreements.

Employee Stock Purchase Plan ("ESPP")

The ESPP allows a maximum of 450,000 shares of common stock to be purchased in aggregate for all employees. As of March 31, 2016 and December 31, 2015, 316,990 and 310,040 shares had been purchased, respectively, and there remained a negligible amount of uninvested employee contributions in the ESPP at March 31, 2016.
