Fair value of both service-based and performance-based restricted stock units is calculated using the market price of the underlying common stock on the date of grant reduced for anticipated dividend payments on unvested shares. In determining fair value, the Company does not take into account performance-based vesting requirements. Performance-based vesting requirements are taken into account in determining the number of awards expected to vest. For market-based restricted stock units, fair value is calculated using a Monte Carlo simulation with the number of shares that ultimately vest dependent on the Company's total stockholder return measured against the total stockholder return of a select group of peer companies over a three-year period. For an award with performance-based or market-based vesting requirements, the number of shares that ultimately vest can vary from 0% to 200% of target depending on the level of achievement of performance criteria. Unvested shares related to restricted stock units with performance-based vesting conditions are reflected at 100% of their target vesting amount in the table above.

Service-based restricted stock units are expensed on a straight-line basis over the total requisite service period, net of forfeitures. Performance-based restricted stock units subject to graded vesting are expensed on an accelerated attribution basis, net of forfeitures. Market-based restricted stock units without graded vesting features are expensed on a straight-line basis over the requisite service period, net of forfeitures.

As of July 30, 2016, there was $48.8 million, $2.4 million and $3.5 million of total unrecognized compensation cost, net of estimated forfeitures, related to service-based, performance-based and market-based restricted stock units, respectively. The unrecognized compensation cost is expected to be recognized over a weighted-average period of 17 months, 16 months and 15 months for service-based, performance-based and market-based restricted stock units, respectively.
