11.	SHARE-BASED COMPENSATION

Share-Based Plans

As of September 30, 2017, we had share-based awards outstanding under the following plans: (1) the 2008 Non-Employee Director Long-Term Incentive Plan (“2008 Director LTIP”), (2) the 2017 Non-Employee Director Long-Term Incentive Plan (“2017 Director LTIP”) and (3) the 2012 Employee Long-Term Incentive Plan ("2012 Employee LTIP"). Both of the share-based plans define fair market value as the previous trading day's closing price when the grant date falls on a date the stock was not traded.

Restricted Stock Activity

For the six months ended September 30, 2017, we granted 535 restricted shares under the 2008 Director LTIP, 5,112 restricted shares under the 2017 Director LTIP, and 66,530 restricted shares under the 2012 Employee LTIP. For the six months ended September 30, 2016, we granted 10,990 restricted shares under the 2008 Director LTIP, and 134,538 restricted shares under the 2012 Employee LTIP. A summary of the restricted shares is as follows:

	Number of Shares			Weighted Average Grant-date Fair Value

Nonvested April 1, 2017		371,689		$	40.45
Granted		72,177		$	80.21
Vested		(155,811	)	$	38.51
Forfeited		(4,108	)	$	39.37
Nonvested September 30, 2017		283,947		$	51.64

Upon each vesting period of the restricted stock awards, employees are subject to minimum tax withholding obligations. Under the 2012 Employee LTIP, we may purchase a sufficient number of shares due to the participant to satisfy their minimum tax withholding on employee stock awards. For the six months ended September 30, 2017, the Company had acquired 57,725 shares of common stock at a value of $4.4 million to satisfy tax withholding obligations relating to the vesting of employees’ restricted stock, which was included in treasury stock.

Compensation Expense

We recognize compensation cost for awards of restricted stock with graded vesting on a straight line basis over the requisite service period. There are no additional conditions for vesting other than service conditions. During the three months ended September 30, 2017 and 2016, we recognized $1.5 million and $1.4 million, respectively, of total share-based compensation expense. During the six months ended September 30, 2017 and 2016, we recognized $3.0 million and $2.9 million, respectively, of total share-based compensation expense. Unrecognized compensation expense related to nonvested restricted stock was $12.7 million as of September 30, 2017, which will be fully recognized over the next thirty-three (33) months.

We also provide our employees with a contributory 401(k) profit sharing plan. We may make contributions to the plan. These contributions are not required and whether or not we choose to make them is entirely within our discretion. Our employer contributions to the plan are fully vested at all times. For the three months ended September 30, 2017 and 2016, our estimated contribution expense for the plan was $0.5 million and $0.4 million, respectively. For the six months ended September 30, 2017 and 2016, our estimated contribution expense for the plan was $1.1 million and $0.8 million, respectively.
