(a)
The derivative asset and liability balances are presented net of counterparty credit considerations.
(b)
Generally, significant increases (decreases) in this input in isolation would result in a significantly lower (higher) fair value measurement.
(c)
Counterparty credit risk is applied only to counterparties with derivative asset balances. Ameren Missouri and Ameren Illinois credit risk is applied only to counterparties with derivative liability balances.
(d)
Not applicable.
(e)
Generally, significant increases (decreases) in this input in isolation would result in a significantly higher (lower) fair value measurement.
(f)
Escalation rate applies to fuel oil prices 2017 and beyond.
(g)
Power valuations use visible third-party pricing evaluated by month for peak and off-peak demand through 2018. Valuations beyond 2018 use fundamentally modeled pricing by month for peak and off-peak demand.
(h)
The balance at Ameren is comprised of Ameren Missouri and Ameren Illinois power contracts, which respond differently to unobservable input changes due to their opposing positions. As such, refer to the power sensitivity analysis for each company above.
(i)
Escalation rate applies to power prices 2026 and beyond.
