leveraged performance units during the year ended may 31 , 2015 , certain executives were granted performance units that we refer to as 201cleveraged performance units , 201d or 201clpus . 201d lpus contain a market condition based on our relative stock price growth over a three-year performance period .
the lpus contain a minimum threshold performance which , if not met , would result in no payout .
the lpus also contain a maximum award opportunity set as a fixed dollar and fixed number of shares .
after the three-year performance period , which concluded in october 2017 , one-third of the earned units converted to unrestricted common stock .
the remaining two-thirds converted to restricted stock that will vest in equal installments on each of the first two anniversaries of the conversion date .
we recognize share-based compensation expense based on the grant date fair value of the lpus , as determined by use of a monte carlo model , on a straight-line basis over the requisite service period for each separately vesting portion of the lpu award .
the following table summarizes the changes in unvested restricted stock and performance awards for the year ended december 31 , 2017 , the 2016 fiscal transition period and for the years ended may 31 , 2016 and 2015 : shares weighted-average grant-date fair value ( in thousands ) .
