  • Ameren May Defer Interest Payments For Up to 10 Consecutive Years Per Deferral Period (new) — The issuer has a broad right to defer interest for up to 10 years, which increases credit risk and may depress the notes' market value.
  • The Notes Rank Junior to All Existing and Future Senior Indebtedness (new) — Subordination to $5.1 billion of senior debt at the parent level means noteholders would be paid only after senior creditors in a default or liquidation.
  • Ameren Is a Holding Company That Derives Substantially All of Its Income From Its Operating Subsidiaries (new) — The holding company structure means noteholders depend on dividends from subsidiaries that have their own substantial debt ($17.1 billion), which ranks ahead of Ameren's equity interest.
