Explanation of Responses:
( 1)	Balance includes shares acquired through dividend reinvestment.
( 2)	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 as of January 31, 2017.
( 3)	1 for 1
( 4)	The Board approved the performance results for the performance-adjusted restricted stock unit grant (RSUP19), and this award will vest on March 1, 2017. Performance targets were achieved, so the award will be paid out at a performance rate of 162%.
( 5)	This holding reflects phantom stock payable in cash upon retirement or other termination of employment under the FirstEnergy Corp. Executive Deferred Compensation Plan. Each share of phantom stock is the economic equivalent of one share of common stock.
