that these costs would be recovered from customers with no material adverse effect on its results of operations, financial position, or liquidity.
Ameren’s and Ameren Missouri’s earnings could benefit from increased investment to comply with environmental regulations if those investments are reflected and recovered on a timely basis in customer rates.
‰ The Ameren Companies have multiyear credit agreements that cumulatively provide $2.1 billion of credit through December 2022, subject to a 364-day repayment term for Ameren Missouri and Ameren Illinois, with the option to seek incremental commitments to increase the cumulative credit provided to $2.5 billion.
See Note 4 – Short-term Debt and Liquidity under Part II, Item 8, of this report for additional information regarding the Credit Agreements.
Ameren, Ameren Missouri, and Ameren Illinois believe that their liquidity is adequate given their expected operating cash flows, capital expenditures, and related financing plans.
However, there can be no assurance that significant changes in economic conditions, disruptions in the capital and credit markets, or other unforeseen events will not materially affect their ability to execute their expected operating, capital, or financing plans.
‰ Federal income tax legislation enacted under the TCJA will continue to have significant impacts on our results of operations, financial position, liquidity, and financial metrics.
The TCJA, among other things, reduced the federal statutory corporate income tax rate from 35% to 21%, effective January 1, 2018.
Customer rates were reduced to reflect the lower income tax rate, without a corresponding reduction in income tax payments because of our use of net operating losses and tax credit carryforwards until about 2020.
Customer rates were also reduced to reflect the return of excess deferred taxes.
The result of these customer rate reductions is a decrease in operating cash flows in the near term.
Over time, the decrease in operating cash flows will be offset as temporary differences between book and taxable income reverse, and by increased customer rates due to higher rate base amounts resulting from lower accumulated deferred income tax liabilities.
‰ Ameren Missouri expects a decrease in operating cash flows of approximately $100 million in 2019 compared with 2018, as a result of the TCJA.
Over time, the decrease in operating cash flows will be offset as temporary differences between book and taxable income reverse, and by increased customer rates due to higher rate base amounts, once approved by the MoPSC, resulting from lower accumulated deferred income tax liabilities.
‰ The following table presents the net regulatory liabilities associated with excess deferred taxes as of December 31, 2018, and the related amortization periods:
## Table 0 ##
‰ In 2018, our rate-regulated businesses began to amortize excess deferred taxes.
Ameren Illinois and ATXI’s 2018 income tax expense reflect a full year of amortization, while Ameren Missouri’s 2018 income tax expense reflects five months of amortization related to its electric business, in accordance with a MoPSC order received in July 2018.
The amortization of such balances related to Ameren Missouri’s gas business started in January 2019, in accordance with a MoPSC order received in December 2018.
These amortizations reduce our income tax expense and effective tax rates.
Due to formula ratemaking, Ameren Illinois Electric Distribution and Ameren Transmission have an offsetting reduction in revenue from customers, with no overall impact on earnings.
Ameren Missouri and Ameren Illinois Natural Gas 2019 interim period earnings may be affected by timing differences between income tax expense and revenue reductions based on their revenue patterns; however, no material impact to year-over-year earnings is expected.
‰ As of December 31, 2018, Ameren had $91 million in tax benefits from federal and state net operating loss carryforwards and $127 million in federal and state income tax credit carryforwards.
These carryforwards are expected to largely offset income tax obligations in 2019.
Ameren does not expect to make material federal or state income tax payments over the next five years based on planned capital expenditures and related income tax credits.
Consistent with the tax allocation agreement between Ameren (parent) and its subsidiaries, Ameren Missouri expects to make material income tax payments to Ameren (parent) in 2019 and 2020 and immaterial payments in 2021 through 2023 based on planned capital expenditures and related income tax credits, while Ameren Illinois expects to make material income tax payments to Ameren (parent) in 2020 through 2023.
‰ Ameren expects its cash used for currently planned capital expenditures and dividends to exceed cash provided by operating activities over the next several years.
To fund a portion of these cash requirements, beginning in the first quarter of 2018, Ameren began using newly issued shares, rather than market-purchased shares, to satisfy requirements under its DRPlus and employee benefit plans and expects to continue to do so over the next five years.
Ameren also plans to issue incremental common equity to fund a portion of Ameren Missouri’s wind generation investments.
Ameren, Ameren Missouri, and Ameren Illinois expect their respective equity to total capitalization levels over the period ending December 2023 to remain in-line with their respective equity to total capitalization levels as of December 31, 2018.

Table 44: Allowance for Loan and Lease Losses
## Table 1 ##
As further described in the Consolidated Income Statement Review section of this Item 7, the provision for credit losses totaled $1.0 billion for 2012 compared to $1.2 billion for 2011.
For 2012, the provision for commercial lending credit losses declined by $39 million or 22% from 2011.
Similarly, the provision for consumer lending credit losses decreased $126 million or 13% from 2011.
At December 31, 2012, total ALLL to total nonperforming loans was 124%.
The comparable amount for December 31, 2011 was 122%.
These ratios are 79% and 84%, respectively, when excluding the $1.5 billion and $1.4 billion, respectively, of allowance at December 31, 2012 and December 31, 2011 allocated to consumer loans and lines of credit not secured by residential real estate and purchased impaired loans.
We have excluded consumer loans and lines of credit not secured by real estate as they are charged off after 120 to 180 days past due and not placed on nonperforming status.
Additionally, we have excluded purchased impaired loans as they are considered performing regardless of their delinquency status as interest is accreted based on our estimate of expected cash flows and additional allowance is recorded when these cash flows are below recorded investment.
See Table 33: Nonperforming Assets By Type within this Credit Risk Management section for additional information.
The ALLL balance increases or decreases across periods in relation to fluctuating risk factors, including asset quality trends, charge-offs and changes in aggregate portfolio balances.
During 2012, improving asset quality trends, including, but not limited to, delinquency status, improving economic conditions, realization of previously estimated losses through charge-offs and overall portfolio growth, combined to result in reducing the estimated credit losses within the portfolio.
As a result, the ALLL balance declined $311 million, or 7%, to $4.0 billion during the year ended December 31, 2012.
See Note 7 Allowances for Loan and Lease Losses and Unfunded Loan Commitments and Letters of Credit and Note 6 Purchased Loans in the Notes To Consolidated Financial Statements in Item 8 of this Report regarding changes in the ALLL and in the allowance for unfunded loan commitments and letters of credit.
CREDIT DEFAULT SWAPS From a credit risk management perspective, we use credit default swaps (CDS) as a tool to manage risk concentrations in the credit portfolio.
That risk management could come from protection purchased or sold in the form of single name or index products.
When we buy loss protection by purchasing a CDS, we pay a fee to the seller, or CDS counterparty, in return for the right to receive a payment if a specified credit event occurs for a particular obligor or reference entity.
When we sell protection, we receive a CDS premium from the buyer in return for PNC’s obligation to pay the buyer if a specified credit event occurs for a particular obligor or reference entity.
We evaluate the counterparty credit worthiness for all our CDS activities.
Counterparty creditworthiness is approved based on a review of credit quality in accordance with our traditional credit quality standards and credit policies.
The credit risk of our counterparties is monitored in the normal course of business.
In addition, all counterparty credit lines are subject to collateral thresholds and exposures above these thresholds are secured.
CDSs are included in the “Derivatives not designated as hedging instruments under GAAP” section of Table 54: Financial Derivatives Summary in the Financial Derivatives section of this Risk Management discussion.
