(1) Balance includes 193 shares acquired on June 8, 2018 through automatic dividend reinvestment.
(2) Phantom stock units (which are in the form of deferred stock units) converted from the legacy Constellation Energy Group Inc. (CEG) Deferred Compensation Plan for Non-employee Directors to phantom units of Exelon common stock at the rate of 0.93 Exelon units for each unit of CEG. Units will be settled in cash on a 1 for 1 basis upon the termination of the reporting person's service on the Exelon board of directors. Balance updated to reflect additional stock units credited to the account through the dividend reinvestment feature of the plan.
(3) Balance includes 372 shares acquired on June 8, 2018 through automatic dividend reinvestment.
(4) Phantom share equivalents acquired through regular periodic contributions of deferred board compensation and the reinvestment of dividend equivalents in reporting person's Exelon stock fund account under multi-fund, non-qualified deferred compensation plan. The unitized fund consists of Exelon common stock and short term investments and will be settled in cash upon the reporting person's separation from the board for any reason. The balance of such phantom share equivalents may fluctuate from time to time due to fluctuations in the fund composition.
(5) Balance includes 181 shares equivalents accrued on May 14, 2018 through automatic dividend reinvestment.
