ITEM 8.01

Other Events.

On February 18, 2011, Ameren Illinois Company (“AIC”) filed a request with the Illinois Commerce Commission (“ICC”) seeking approval to increase its electric delivery service rates by $60 million annually. The electric rate increase request is based on an 11.25 percent return on equity, a capital structure composed of 53 percent equity and an electric rate base of $1.997 billion.

Also on February 18, 2011, AIC filed a request with the ICC seeking approval to increase its natural gas delivery service rates by $51 million annually. The natural gas rate increase request is based on an 11 percent return on equity, a capital structure composed of 53 percent equity and a rate base of $978 million.

In an attempt to limit regulatory lag, AIC is using a projected future test year, 2012, as a basis for each of these rate requests. This test year includes higher costs than those incurred in 2010 and projected investments through 2012.

AIC is requesting a rider mechanism for its pension costs. This requested rider mechanism would allow AIC to recover or refund any difference between pension expense incurred and the amount allowed in rates annually subject to an annual reconciliation.

The ICC proceedings relating to the proposed electric and natural gas delivery service rate changes will take place over a period of up to 11 months and decisions by the ICC in such proceedings are required by January 2012. AIC cannot predict the level of any delivery service rate change the ICC may approve, when any rate change may go into effect, or whether any rate increase that may eventually be approved will be sufficient for AIC to recover its costs and earn a reasonable return on its investments when the increase goes into effect.
