The estimated fair value of RSUs was calculated based on the closing price of the Company’s common stock on the date of grant, reduced by the present value of dividends foregone during the vesting period.

The following table summarizes the activity for RSUs for the

six

months ended

July 31, 2018:

	RSUs			Weighted Average Grant Date Fair Value
	(in thousands)
Outstanding at January 31, 2018		653		$	25.10

Released (1)		(252	)		25.56
Forfeited		(13	)		25.13

The number of RSUs released includes shares withheld on behalf of employees to satisfy the minimum statutory tax withholding requirements.

months ended

July 31, 2018,

the Company withheld

75,000

shares for payment of these taxes at a value of

$4.0

million. During the

six

July 31, 2018,

the Company withheld

79,000

shares for payment of these taxes at a value of

$4.2

million.

$22.5

million as of

July 31, 2018.

This cost is expected to be recognized over a weighted-average period of approximately

3.2

years.

SAR Information

The weighted average assumptions used to value SARs granted in the

six

months ended

July 31, 2018

and

2017

are shown in the following table:

	Six Months Ended July 31,
	201 8			201 7
Expected life in years (1)		5.50			5.50
Risk free interest rate (2)		2.80	%		1.82	%
Volatility (3)		31	%		33	%
Dividend rate (4)		0.54	%		0.91	%

____________________________

(

)

The expected life of SARs granted under the stock-based compensation plans is based on historical vested SAR exercise and post-vest forfeiture patterns and includes an estimate of the expected term for SARs that were fully vested and outstanding.

(

)

The risk-free interest rate is based on the U.S. Treasury yield for a term consistent with the expected life of SARs in effect at the time of grant.

(

)

The Company estimates the volatility of its common stock at the date of grant based on the historical volatility of the Company’s common stock for a period equivalent to the expected life of the SARs, which it believes is representative of the expected volatility over the expected life of the SARs.

(

)

The Company expects to continue paying quarterly dividends at the same rate as the

six

months ending on

July 31, 2018.

The following table summarizes the activity for outstanding SARs for the

six

months ended

July 31, 2018:

	SARs (in thousands)			Weighted Average Exercise Price per Share		Weighted Average Remaining Contractual Term (years)		Aggregate Intrinsic Value (in thousands)
Outstanding at January 31, 2018		3,024		$	17.78
Granted		380			53.50
Exercised		(384	)		9.39
Expired		(5	)		8.97
Forfeited		(1	)		19.40

Vested and exercisable at July 31, 2018		2,064		$	17.02		3.4	$	64,899

The aggregate intrinsic value in the table above represents the total pretax intrinsic value (the aggregate difference between the closing stock price of the Company’s common stock based on the last trading day as of

July 31, 2018,

and the exercise price for in-the-money SARs) that would have been received by the holders if all SARs had been exercised on

July 31, 2018.

six

months ended

July 31, 2018

$12.2

million. The weighted average grant date fair value per share of SARs granted in the

three
