The total recognized tax benefit is reported at the federal statutory rate net of the tax valuation allowance. Stock-based compensation cost is measured at the grant date, based on the fair value of the award, and is recognized over the requisite service period, which is either immediate recognition if the employee is eligible to retire, or on a straight-line basis until the earlier of either the date of retirement eligibility or the end of the vesting period. There was no stock-based compensation granted in the three and six months ended June 30, 2014. As of June 30, 2014, there was $0.4 million of unrecognized compensation cost, adjusted for estimated forfeitures, related to non-vested restricted shares and restricted stock units granted in prior years. That cost is expected to be recognized over a weighted-average period of 10 months.
