(1) The amount listed in Table II represents 50% of the original RSUP16 award, which was the minimum amount guaranteed to be paid out upon vesting. The award vested on March 4, 2014 and because the performance targets were achieved, the award was paid out at a performance rate of 150%. The shares coded "A" represent the portion attributable to this performance adjustment. The shares coded "F" were withheld to cover income tax obligations associated with the payout.
(2) 1 for 1
(3) Balance includes shares acquired through dividend reinvestment.
(4) FE's 401(k) Plan includes a unitized fund invested in FE stock, in which the reporting person may invest, which includes dividend reinvestment and company match features. The number of shares reported as indirectly held in the 401(k) Plan in this row is an estimate of the number of shares of FE's common stock held in the unitized stock fund and allocated to the reporting person's account.
