Estimated Fair Value of Stock Options Using the Black-Scholes Valuation Model

The fair value of stock options granted during the three months ended April 1, 2016 was estimated as of the grant date using the Black-Scholes valuation model with the following assumptions:

	Three Months Ended April 1, 2016
Expected option term in years (1)		6.0
Expected volatility (2)		33.8	%
Risk-free interest rate (3)		1.6	%
Expected annual dividend yield (4)		—

(1) The expected option term was calculated using the simplified method provided by Codification of Staff Accounting Bulletin Topic 14: “Share-Based Payment”.

(2) The expected volatility was determined based on the historical volatility of the Company’s common stock over the expected option term.

(3) Risk-free interest rate was based upon treasury instrument whose term was one year longer than the expected option term.

(4) The expected annual dividend yield is zero, as the Company does not have plans to issue dividends.
