AMEREN CORPORATION (parent company only)

NOTES TO CONDENSED FINANCIAL STATEMENTS

December 31, 2015

NOTE 1 – BASIS OF PRESENTATION

Ameren Corporation (parent company only) is a public utility holding company that conducts substantially all of its business operations through its subsidiaries. In accordance with authoritative accounting guidance, Ameren Corporation (parent company only) has accounted for wholly owned subsidiaries using the equity method. These financial statements are presented on a condensed basis.

See Note 1 – Summary of Significant Accounting Policies under Part II, Item 8, of this report for additional information.

Accounting Changes and Other Matters

Presentation of Debt Issuance Costs

During 2015, the FASB issued authoritative accounting guidance requiring debt issuance costs to be presented as a reduction to the associated debt liability. Previously, debt issuance costs were presented in "Other assets" on Ameren Corporation's (parent company only) balance sheet. Ameren Corporation (parent company only) early adopted this standard in 2015. Retrospective application of the new guidance had no impact on Ameren Corporation's (parent company only) balance sheet at December 31, 2014. See Note 5 – Long-term Debt and Equity Financings under Part II, Item 8, of this report for additional information.

Balance Sheet Classification of Deferred Income Taxes

During 2015, the FASB issued authoritative accounting guidance requiring all deferred tax assets and liabilities, along with any related valuation allowances, to be classified as noncurrent on the balance sheet. Previously, the current portion of deferred taxes was presented as

"Current accumulated deferred income taxes, net" and the noncurrent portion of deferred taxes was presented as "Accumulated deferred income taxes, net" on Ameren Corporation's (parent company only) balance sheet. Ameren Corporation (parent company only) early adopted this standard in 2015 and applied the guidance retrospectively. At December 31, 2014, the current portion of deferred income taxes of $143 million previously presented as "Current accumulated deferred income taxes, net" on Ameren Corporation's (parent company only) balance sheet was reclassified and presented in "Accumulated deferred income taxes, net" for comparative purposes.

Additional disclosures relating to the parent company financial statements are included within the combined notes under Part II, Item 8, of this report. See Note 1 – Summary of Significant Accounting Policies and Note 14 – Related Party Transactions under Part II, Item 8, of this report for information on the tax allocation agreement between Ameren Corporation (parent company only) and its subsidiaries.

NOTE 2 – SHORT-TERM DEBT AND LIQUIDITY

Ameren, Ameren Services, and other non-state-regulated Ameren subsidiaries have the ability, subject to Ameren parent company and applicable regulatory short-term borrowing authorizations, to access funding from the Credit Agreements and the commercial paper programs through a non-state-regulated subsidiary money pool agreement. All participants may borrow from or lend to the non-state-regulated money pool. The total amount available to pool participants from the non-state-regulated subsidiary money pool at any given time is reduced by the amount of borrowings made by participants, but is increased to the extent that the pool participants advance surplus funds to the non-state-regulated subsidiary money pool or remit funds from other external sources. The non-state-regulated subsidiary money pool was established to coordinate and to provide short-term cash and working capital for the participants. Participants receiving a loan under the non-state-regulated subsidiary money pool agreement must repay the principal amount of such loan, together with accrued interest. The rate of interest depends on the composition of internal and external funds in the non-state-regulated subsidiary money pool. Interest revenues and interest charges related to non-state-regulated money pool advances and borrowings were immaterial in 2014 and 2015.

Ameren Corporation (parent company only) had a total of $36 million in guarantees outstanding primarily for ATXI that were not recorded on its December 31, 2015 balance sheet. The ATXI guarantees were issued to local governments as assurance for potential remediation of damage caused by ATXI construction.

See Note 4 – Short-term Debt and Liquidity under Part II, Item 8, of this report for a description and details of short-term debt and liquidity needs of Ameren Corporation (parent company only).

NOTE 3 – LONG-TERM OBLIGATIONS

In November 2015, Ameren Corporation (parent company only) issued $350 million of 2.70% senior unsecured notes due November 15, 2020, with interest payable semiannually on May 15 and November 15 of each year, beginning May 15, 2016. Ameren (parent) received proceeds of $348 million, which were used to repay a portion of short-term debt.

In November 2015, Ameren Corporation (parent company only) issued $350 million of 3.65% senior unsecured notes due February 15, 2026, with interest payable semiannually on February 15 and August 15 of each year, beginning February 15, 2016. Ameren (parent) received proceeds of $347 million, which were used to repay a portion of short-term debt.

In May 2014, Ameren Corporation (parent company only) repaid at maturity $425 million of its 8.875% senior unsecured notes, plus accrued interest. The notes were repaid with proceeds from commercial paper issuances.

See Note 5 – Long-term Debt and Equity Financings under Part II, Item 8, of this report for additional information on Ameren Corporation's (parent company only) long-term debt.

NOTE 4 – COMMITMENTS AND CONTINGENCIES

See Note 15 – Commitments and Contingencies under Part II, Item 8, of this report for a description of all material contingencies of Ameren Corporation (parent company only).

NOTE 5 – DIVESTITURE TRANSACTIONS AND DISCONTINUED OPERATIONS

On December 2, 2013, Ameren completed the divestiture of New AER to IPH in accordance with the transaction agreement between Ameren and IPH dated March 14, 2013, as amended by a letter agreement dated December 2, 2013. As a result of the divestiture in 2013, Ameren Corporation (parent company only) recorded a pretax loss on disposal of $201 million. This charge was included within "Net Loss Attributable to Ameren Common Shareholders – Discontinued Operations" in the Ameren Corporation (parent company only) Condensed Statement of Income (Loss) and Comprehensive Income (Loss) for the year ended December 31, 2013.

During 2015, based on the completion of the IRS audit, Ameren Corporation (parent company only) removed a $53 million reserve for unrecognized tax benefits recorded in 2013 and recognized a tax benefit from discontinued operations. See Note 13 – Income Taxes under Part II, Item 8, of this report for additional information regarding Ameren Corporation's (parent company only) uncertain tax positions.

In 2015, Ameren paid $25 million related to a previously-recorded liability pursuant to the transaction agreement between Ameren and IPH with no resulting additional impact to its results of operations.

See Note 16 – Divestiture Transactions and Discontinued Operations under Part II, Item 8, of this report for additional information regarding the divestiture transactions and discontinued operations.
