Share-Based Plans

We have share-based awards outstanding under the following plans: (1) the Amended and Restated 1998 Stock Incentive Plan (the “Amended LTIP (2003)”), (2) the 2008 Non-Employee Director Long-Term Incentive Plan (“2008 Director LTIP”), (3) the 2008 Employee Long-Term Incentive Plan (“2008 Employee LTIP”) and (4) the 2012 Employee Long-Term Incentive Plan ("2012 Employee LTIP"). All the share-based plans defined fair market value as the previous trading day's closing price when the grant date falls on a date the stock was not traded.

For a summary of descriptions and vesting periods of the Amended LTIP (2003), the 2008 Director LTIP, the 2008 Employee LTIP, and the 2012 Employee LTIP discussed above, refer to our 2013 Annual Report.

We issue shares from our authorized but unissued common stock to satisfy stock option exercises.  At June 30, 2013, all of our stock options are vested.

Upon each vesting period of the restricted stock awards, employees are subject to minimum tax withholding obligations. The 2008 Director LTIP and 2012 Employee LTIP allow us, at the participant’s election, to withhold a sufficient number of shares due to the participant to satisfy their minimum tax withholding on employee stock awards. During the three months ended June 30, 2013, we withheld 28,222 shares of common stock at a value of $1.7 million, 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 and estimate the forfeiture rate to be zero, which is based on historical experience. There are no additional conditions for vesting other than service conditions. During the three months ended June 30, 2013 and 2012, we recognized $881 thousand and $663 thousand, respectively, of total share-based compensation expense. Unrecognized compensation expense related to non-vested restricted stock was $7.7 million, which will be fully recognized over the next 36 months.

We also provide our employees with a contributory 401(k) profit sharing plan. Employer contribution percentages are determined by us and are discretionary each year. The employer contributions vest pro-ratably over a four-year service period by the employees, after which, all employer contributions will be fully vested. For the three months ended June 30, 2013 and 2012, our contribution expense for the plan was approximately $377 thousand and $229 thousand, respectively.
