Share-based Payment Arrangement [Abstract]

Schedule of Share-based Payment Award, Stock Options, Valuation Assumptions

The fair value of the stock options granted was estimated on the date of the grant using a Black-Scholes option-pricing model that uses the assumptions noted in the following table.

	FISCAL YEAR ENDED
Black-Scholes Valuation Assumptions  (1)	February 29, 2020		March 2, 2019		March 3, 2018
Weighted Average Expected Life (in years)  (2)	7.6		6.7		6.7
Weighted Average Expected Volatility  (3)	39.41	%	34.96	%	26.49	%
Weighted Average Risk Free Interest Rates  (4)	2.39	%	2.92	%	2.17	%
Expected Dividend Yield (5)	4.34	%	3.80	%	1.60	%

(1) Forfeitures are estimated based on historical experience.

(2) The expected life of stock options is estimated based on historical experience.

(3) Expected volatility is based on the average of historical and implied volatility. The historical volatility is determined by observing actual prices of the Company’s stock over a period commensurate with the expected life of the awards. The implied volatility represents the implied volatility of the Company’s call options, which are actively traded on multiple exchanges, had remaining maturities in excess of twelve months, had market prices close to the exercise prices of the employee stock options and were measured on the stock option grant date.

(4) Based on the U.S. Treasury constant maturity interest rate whose term is consistent with the expected life of the stock options.

(5) Expected dividend yield is estimated based on anticipated dividend payouts.
