If this is truly a merger (versus a buyout of PGN by Duke), why is the name the "New Duke Energy" being used in communications now? If it's a merger, why not select a new company name that better describes the new entity?

Both companies have a rich history with over a century of service. The brand equity that’s been built in serving customers and supporting communities over this time provides tremendous value going forward. The new Duke Energy will be able to capitalize on its strong reputation with all stakeholders. Also, using the Duke Energy name provides a significant cost savings over transitioning to a new name.
