“We remain committed at all levels of the company to the highest standards of integrity and ethical behavior and we look forward to building on the trust of our customers as we continue to move forward,” Butler said.

A Securities and Exchange Commission investigation is ongoing. Exelon recorded a $46.2 million “loss contingency” in the second quarter related to the probe, the company said Wednesday in its quarterly SEC report.

ComEd is also challenging an audit report released July 27 by the Federal Energy Regulatory Commission that alleges the utility overcharged transmission customers by misallocating certain overhead costs to capitalized construction costs, Exelon said in its quarterly report.

Exelon set aside $11 million in the first quarter to cover potential liabilities from the FERC audit.

The resolution of the audit could result in losses above what has been set aside, Exelon said.

On the financial front, Exelon’s second-quarter income fell 26% to $343 million on $4.8 billion in revenue from $465 million on $4.2 billion in revenue in the year-ago quarter, the utility company said. The decrease in earnings was partly driven by higher interest expense caused by rising interest rates and higher debt levels as well as unfavorable weather, according to Jones.

Not including certain one-time factors, second-quarter adjusted earnings per share fell 7% to 41 cents from 44 cents in the same quarter last year.

Exelon has more than 10 million customers in Delaware, the District of Columbia, Illinois, Maryland, New Jersey and Pennsylvania through its transmission and distribution utilities: Atlantic City Electric, Baltimore Gas and Electric, Commonwealth Edison, Delmarva Power & Light, PECO Energy and Pepco.
