So Duke energy pays an annual dividend of 10% to investors/shareholders no matter what.

Several years ago (2015) Duke got hugely fined ($102,000,000) for dumping coal ash into local water systems. The fine stipulated they weren’t allowed to pass the cost of the fine on to consumers in North Carolina where the fine was levied.

So Duke passed the entirety of the fine into the energy costs of their South Carolina customers. 10% dividend paid out as usual despite taking a massive loss that year. I guess big business never loses.
