The total recognized tax benefit is reported at the federal statutory rate net of the tax valuation allowance in 2012. 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. As of June 30, 2012, there was $4.3 million of unrecognized compensation cost, adjusted for estimated forfeitures, related to non-vested stock-based payments granted, of which $3.9 million relates to restricted shares and restricted stock units, and $0.4 million relates to stock options. That cost is expected to be recognized over a weighted-average period of 1.7 years. On February 15, 2012, USEC's Board of Directors voted to discontinue USEC's employee stock purchase plan effective immediately. Given the recent volatility of USEC stock and the holding requirement for all shares purchased through the plan, the Board determined that it was prudent to discontinue the Program and refund all amounts credited to participants' accounts to date for the offering period January 1, 2012 through June 30, 2012.
