Company Launches PremierNotes

Duke Energy today launched a program called PremierNotes that will give the company access to a new and diversified source of capital and provide investors with an opportunity to earn attractive interest rates on money invested directly with the company.

PremierNotes is a notes program that provides individuals and other qualified investors an opportunity to make direct investments in new debt of the corporation.

How it works

Under the program, Duke borrows directly from investors by issuing notes. In return, our investors receive a competitive floating rate of interest that is attractive compared to other cash alternatives, like bank accounts, short-term CDs and money-market mutual funds, and their money is available when they need it.

The program will be open to the public, including employees.

Duke uses investments in the PremierNotes program to provide the company with an additional source of liquidity and to diversify its capital funding sources.

“As we continue to grow our business, having access to diversified funding sources at competitive rates is important to finance the capital requirements of the company in a cost-effective manner,” said Stephen G. De May, senior vice president, investor relations and treasurer.
