Stock Based Compensation
5.  Stock-Based Compensation

The Company's compensation expense recorded in connection with grants of restricted stock and restricted stock units for the three and six months ended June 30, 2012 and 2011 was calculated net of forfeitures estimated from 0% to 10% of the shares granted.  For all awards with graded vesting other than awards with performance-based vesting conditions, the Company records compensation expense for the entire award on a straight-line basis (or if, applicable, on the accelerated method) over the requisite service period.  For graded-vesting awards with performance-based vesting conditions, total compensation expense is recognized over the requisite service period for each separately vesting tranche of the award as if the award is, in substance, multiple awards once the performance target is deemed probable of achievement.  Performance goals are evaluated quarterly.  If such goals are not ultimately met or it is not probable the goals will be achieved, no compensation expense is recognized and any previously recognized compensation expense is reversed.

Current year grants of restricted shares under the Company's Omnibus Stock Incentive Plan were as follows (amounts in thousands except for value per share):
