Investor Verification Checklist
- Verify the exact interest rate differential between the new 4.600% Notes and the retired 5.300% Notes to assess interest expense savings.
- Confirm the status and timeline of the acquisition of the Tennessee natural gas business from Piedmont Natural Gas Company.
- Review the Supplemental Indenture (Exhibit 4.1) for specific covenants, prepayment terms, and redemption features of the 2031 Notes.
- Check subsequent filings for the final allocation of "remaining net proceeds" between the acquisition and general corporate purposes.
