We determine the fair value of restricted stock units based on the closing market price of the Company's common stock on the grant date. As of June 30, 2016, we had $37.0 million of unamortized deferred compensation related to unvested restricted stock units, which we anticipate recognizing over varying periods into 2020. Shares that vested during the three months ended June 30, 2016 and 2015, had grant date fair values of $0.9 million and $1.2 million, respectively, and $8.6 million and $4.6 million for the six months ended June 30, 2016 and 2015, respectively. Shares we granted during the three months ended June 30, 2016 and 2015, had grant date fair values of $5.4 million and $1.8 million, respectively, and $26.9 million and $21.0 million for the six months ended June 30, 2016 and 2015, respectively.
