leveraged performance units during fiscal 2015 , certain executives were granted performance units that we refer to as leveraged performance units , or lpus . 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 , one-third of any earned units converts to unrestricted common stock . the remaining two-thirds convert 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 . total shareholder return units before fiscal 2015 , certain of our executives were granted total shareholder return ( 201ctsr 201d ) units , which are performance-based restricted stock units that are earned based on our total shareholder return over a three-year performance period compared to companies in the s&p 500 . once the performance results are certified , tsr units convert into unrestricted common stock . depending on our performance , the grantee may earn up to 200% ( 200 % ) of the target number of shares . the target number of tsr units for each executive is set by the compensation committee . we recognize share-based compensation expense based on the grant date fair value of the tsr units , as determined by use of a monte carlo model , on a straight-line basis over the vesting period . the following table summarizes the changes in unvested share-based awards for the years ended may 31 , 2016 and 2015 ( shares in thousands ) : shares weighted-average grant-date fair value .
