the performance units granted to certain executives in fiscal 2014 were based on a one-year performance period .
after the compensation committee certified the performance results , 25% ( 25 % ) of the performance units converted to unrestricted shares .
the remaining 75% ( 75 % ) converted to restricted shares that vest in equal installments on each of the first three anniversaries of the conversion date .
the performance units granted to certain executives during fiscal 2015 were based on a three-year performance period .
after the compensation committee certifies the performance results for the three-year period , performance units earned will convert into unrestricted common stock .
the compensation committee may set a range of possible performance-based outcomes for performance units .
depending on the achievement of the performance measures , the grantee may earn up to 200% ( 200 % ) of the target number of shares .
for awards with only performance conditions , we recognize compensation expense over the performance period using the grant date fair value of the award , which is based on the number of shares expected to be earned according to the level of achievement of performance goals .
if the number of shares expected to be earned were to change at any time during the performance period , we would make a cumulative adjustment to share-based compensation expense based on the revised number of shares expected to be earned .
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 .
