#### Column (f)
For each Covered Year, our absolute TSR was calculated based on the yearly percentage change in our cumulative TSR on our common stock, par value $5.00 per share, measured as the quotient of (a) the sum of (i) the cumulative amount of dividends for the period beginning with our closing stock price on the NYSE on December 31, 2019 through and including the last day of the covered year (each, a Measurement Period), assuming dividend reinvestment, plus (ii) the difference between our closing stock price at the end versus the beginning of the Measurement Period, divided by (b) our closing share price at the beginning of the Measurement Period. Each of these yearly percentage changes was then applied to a deemed fixed investment of $100 at the beginning of each Measurement Period to produce the Covered Year-end values of such investment as of the end of the Covered Year, as applicable. Because Covered Years are presented in the table in reverse chronological order (from top to bottom), the table should be read from bottom to top for purposes of understanding cumulative returns over time.

#### Column (g)
The peer group utilized in the table above is the Philadelphia Utilities Sector Index (UTY). For each Covered Year, the peer group cumulative TSR was calculated based on a deemed fixed investment of $100 in the index through each Measurement Period, assuming dividend reinvestment.

#### Column (i)
For purposes of this PvP disclosure, our relative TSR is calculated substantially as described above in our Compensation Discussion and Analysis. See page
