Stock Options
During the thirty-nine weeks ended October 29, 2016, the Company granted stock options under the 2010 Plan. Stock options granted in 2016 under the 2010 Plan vest 25% per year over four years or upon reaching retirement eligibility, defined as providing ten years of service and being at least 55 years old. These options have a ten year contractual life. The expense for stock options is recognized using the straight-line attribution method.

As of October 29, 2016, there was approximately $2.8 million of total unrecognized compensation expense related to stock options, which is expected to be recognized over a weighted average period of approximately 1.6 years.
The Company uses the Black-Scholes-Merton option-pricing model to value stock options granted to employees. The Company's determination of the fair value of stock options is affected by the Company's stock price as well as a number of subjective and complex assumptions. These assumptions include the risk-free interest rate, the Company's expected stock price volatility over the term of the award, expected term of the award, and dividend yield.
The fair value of stock options was estimated at the grant date using the Black-Scholes-Merton option pricing model with the following weighted-average assumptions:

Dividend yield (4)

 


(1)
Represents the yield on U.S. Treasury securities with a term consistent with the expected term of the stock options.
(2)
Primarily based on the historical volatility of the Company's common stock over a period consistent with the expected term of the stock options.
(3)
Beginning in 2016, the Company calculated the expected term assumption using the midpoint scenario, which combines historical exercise data with hypothetical exercise data for outstanding options. The Company believes this data currently represents the best estimate of the expected term of new employee options.
(4)
The Company does not currently plan on paying regular dividends.
Restricted Stock Units and Restricted Stock
During the thirty-nine weeks ended October 29, 2016, the Company granted restricted stock units ("RSUs") under the 2010 Plan, including 0.3 million RSUs with performance conditions. The fair value of RSUs is determined based on the Company's closing stock price on the day prior to the grant date in accordance with the 2010 Plan. The expense for RSUs without performance conditions is recognized using the straight-line attribution method. The expense for RSUs with performance conditions is recognized using the graded vesting method based on the expected achievement of the performance conditions. The RSUs with performance conditions are also subject to time-based vesting. All of the RSUs granted during the thirty-nine weeks ended October 29, 2016 that are earned based on the achievement of performance criteria will vest on April 15, 2019. RSUs without performance conditions vest ratably over four years.
The Company's activity with respect to RSUs and restricted stock, including awards with performance conditions, for the thirty-nine weeks ended October 29, 2016 was as follows:

(1)
Approximately 0.3 million RSUs with three-year performance conditions were granted in the first quarter of 2016. None of these RSUs are currently included as granted in the table above. The number of performance-based RSUs that are ultimately earned may vary from 0% to 200% of target depending on the achievement of predefined financial performance targets.
(2)
Relates to a change in estimate of RSUs with performance conditions granted in 2015. Currently, 112% of the number of shares granted in 2015 are expected to vest based on estimates against predefined financial performance targets.

The total fair value of RSUs and restricted stock that vested during the thirty-nine weeks ended October 29, 2016 was $13.6 million. As of October 29, 2016, there was approximately $22.3 million of total unrecognized compensation expense related to unvested RSUs and restricted stock, which is expected to be recognized over a weighted-average period of approximately 1.7 years.
