FORWARD-LOOKING STATEMENTS
Statements contained in this report that are not of historical fact are forward-looking statements intended to qualify for the safe harbors from liability established by the Private Securities Litigation Reform Act of 1995. These forward-looking statements can be identified as such because the statements include words such as “may,” “believe,” “expect,” “anticipate,” “plan,” “project,” “will,” “projections,” “estimate,” or other words of similar import. Similarly, statements that describe future financial performance or plans or strategies are forward-looking statements. Such forward-looking statements are subject to certain risks and uncertainties that could cause actual results to differ materially from those expressed in, or implied by, such statements. Some, but not all, of the risks and uncertainties of Alliant Energy, IPL and WPL that could materially affect actual results include:
• | IPL’s and WPL’s ability to obtain adequate and timely rate relief to allow for, among other things, earning a return on rate base additions and the recovery of costs, including fuel costs, operating costs, transmission costs, environmental compliance and remediation costs, deferred expenditures, deferred tax assets, capital expenditures, and remaining costs related to EGUs that may be permanently closed, earning their authorized rates of return, and the payments to their parent of expected levels of dividends; |
• | federal and state regulatory or governmental actions, including the impact of energy, tax, financial and health care legislation, and regulatory agency orders; |
• | ability to obtain necessary regulatory approval for capital projects with acceptable conditions; |
• | the impact of customer- and third party-owned generation, including alternative electric suppliers, in IPL’s and WPL’s service territories on system reliability, operating expenses and customers’ demand for electricity; |
• | the impact of energy efficiency, franchise retention and customer disconnects on sales volumes and margins; |
• | the impact that price changes may have on IPL’s and WPL’s customers’ demand for electric, gas and steam services and their ability to pay their bills; |
• | the ability to utilize tax credits and net operating losses generated to date, and those that may be generated in the future, before they expire; |
• | the direct or indirect effects resulting from terrorist incidents, including physical attacks and cyber attacks, or responses to such incidents; |
• | the impact of penalties or third-party claims related to, or in connection with, a failure to maintain the security of personally identifiable information, including associated costs to notify affected persons and to mitigate their information security concerns; |
• | employee workforce factors, including changes in key executives, ability to hire and retain employees with specialized skills, ability to create desired corporate culture, collective bargaining agreements and negotiations, work stoppages or restructurings; |
1 |
• | weather effects on results of utility operations; |
• | issues associated with environmental remediation and environmental compliance, including compliance with the Consent Decree between WPL, the EPA and the Sierra Club, the Consent Decree between IPL, the EPA, the Sierra Club, the State of Iowa and Linn County in Iowa, the Coal Combustion Residuals Rule, future changes in environmental laws and regulations, including the EPA’s regulations for carbon dioxide emissions reductions from new and existing fossil-fueled EGUs, and litigation associated with environmental requirements; |
• | the ability to defend against environmental claims brought by state and federal agencies, such as the EPA, state natural resources agencies or third parties, such as the Sierra Club, and the impact on operating expenses of defending and resolving such claims; |
• | continued access to the capital markets on competitive terms and rates, and the actions of credit rating agencies; |
• | inflation and interest rates; |
• | the impact of the economy in IPL’s and WPL’s service territories and the resulting impacts on sales volumes, margins and the ability to collect unpaid bills; |
• | changes in the price of delivered natural gas, purchased electricity and coal due to shifts in supply and demand caused by market conditions and regulations; |
• | disruptions in the supply and delivery of natural gas, purchased electricity and coal; |
• | changes in the price of transmission services and the ability to recover the cost of transmission services in a timely manner; |
• | developments that adversely impact the ability to implement the strategic plan; |
• | ability to obtain regulatory approval for wind projects with acceptable conditions, to complete construction within the cost caps set by regulators and to meet all requirements to qualify for the full level of production tax credits; |
• | the direct or indirect effects resulting from breakdown or failure of equipment in the operation of electric and gas distribution systems, such as mechanical problems and explosions or fires, and compliance with electric and gas transmission and distribution safety regulations; |
• | issues related to the availability and operations of EGUs, including start-up risks, breakdown or failure of equipment, performance below expected or contracted levels of output or efficiency, operator error, employee safety, transmission constraints, compliance with mandatory reliability standards and risks related to recovery of resulting incremental costs through rates; |
• | impacts that storms or natural disasters in IPL’s and WPL’s service territories may have on their operations and recovery of costs associated with restoration activities; |
• | any material post-closing adjustments related to any past asset divestitures, including the sales of IPL’s Minnesota electric and natural gas assets, and Whiting Petroleum, which could result from, among other things, indemnification agreements, warranties, parental guarantees or litigation; |
• | Alliant Energy’s ability to sustain its dividend payout ratio goal; |
• | changes to costs of providing benefits and related funding requirements of pension and OPEB plans due to the market value of the assets that fund the plans, economic conditions, financial market performance, interest rates, life expectancies and demographics; |
• | material changes in employee-related benefit and compensation costs; |
• | risks associated with operation and ownership of non-utility holdings; |
• | changes in technology that alter the channels through which customers buy or utilize Alliant Energy’s, IPL’s or WPL’s products and services; |
• | impacts on equity income from unconsolidated investments due to further potential changes to ATC’s authorized return on equity; |
• | impacts of IPL’s future tax benefits from Iowa rate-making practices, including deductions for repairs expenditures, allocation of mixed service costs and state depreciation, and recoverability of the associated regulatory assets from customers, when the differences reverse in future periods; |
• | the impacts of adjustments made to deferred tax assets and liabilities from changes in the tax laws; |
• | changes to the creditworthiness of counterparties with which Alliant Energy, IPL and WPL have contractual arrangements, including participants in the energy markets and fuel suppliers and transporters; |
• | current or future litigation, regulatory investigations, proceedings or inquiries; |
• | reputational damage from negative publicity, protests, fines, penalties and other negative consequences resulting in regulatory and/or legal actions; |
• | the effect of accounting standards issued periodically by standard-setting bodies; |
• | the ability to successfully complete tax audits and changes in tax accounting methods with no material impact on earnings and cash flows; and |
• | factors listed in MDA and Risk Factors in Item 1A in the 2017 Form 10-K. |
Alliant Energy, IPL and WPL each assume no obligation, and disclaim any duty, to update the forward-looking statements in this report, except as required by law.

ALLIANT ENERGY CORPORATION
INTERSTATE POWER AND LIGHT COMPANY
WISCONSIN POWER AND LIGHT COMPANY
COMBINED NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)
NOTE 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
NOTE 1(a) General - The interim unaudited Financial Statements included herein have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission. Accordingly, certain information and note disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted, although management believes that the disclosures are adequate to make the information presented not misleading. These Financial Statements should be read in conjunction with the financial statements and the notes thereto included in the latest combined Annual Report on Form 10-K.
In the opinion of management, all adjustments, which unless otherwise noted are normal and recurring in nature, necessary for a fair presentation of the results of operations, financial position and cash flows have been made. Results for the nine months ended September 30, 2018 are not necessarily indicative of results that may be expected for the year ending December 31, 2018. A change in management’s estimates or assumptions could have a material impact on financial condition and results of operations during the period in which such change occurred. Certain prior period amounts in the Financial Statements and Notes have been reclassified to conform to the current period presentation for comparative purposes, including modifications to the presentation of the components of net periodic benefit costs for defined benefit pension and other postretirement plans in the income statements as discussed in Note 1(d), restricted cash and cash receipts on sold receivables in the cash flows statements as discussed in Note 1(d), and segment reporting as discussed in Note 14.
Discontinued operations reported in Alliant Energy’s income statements is related to various warranty claims associated with the sale of RMT, Inc. in 2013, which have resulted in operating expenses and income subsequent to the sale.
NOTE 1(b) Cash, Cash Equivalents and Restricted Cash - At September 30, 2018, Alliant Energy’s and IPL’s cash and cash equivalents included $228 million of money market fund investments with a 2% interest rate. At September 30, 2018 and December 31, 2017, restricted cash primarily related to deposits with trustees and borrowing requirements in Sheboygan Power, LLC’s debt agreement. Refer to Note 1(d) for discussion of revisions to the cash flows statements to include immaterial restricted cash amounts.
NOTE 1(c) Revenue Recognition -
Utility - Revenues from Alliant Energy’s utility business are primarily from retail and wholesale electric and gas sales to customers. Utility revenues are recognized over time as services are rendered or commodities are delivered to customers, and include billed and unbilled components. The billed component is based on the reading of customers’ meters, which occurs on a systematic basis throughout each reporting period and represents the fair value of the services provided or commodities delivered. The unbilled component is estimated and recorded at the end of each reporting period based on estimated amounts of energy delivered to customers since the date of each customer’s last meter reading. The unbilled revenue is based on estimates of daily system demand volumes, customer usage by class, temperature impacts, line losses and the most recent customer rates.
IPL and WPL accrue revenues from their wholesale customers to the extent that the actual net revenue requirements calculated in accordance with FERC-approved formula rates for the reporting period are higher or lower than the amounts billed to wholesale customers during such period. Regulatory assets or regulatory liabilities are recorded as the offset for these accrued revenues under formulaic rate-making programs. As of September 30, 2018, the related amounts accrued for IPL and WPL were not material.
IPL and WPL participate in bid/offer-based wholesale energy and ancillary services markets operated by MISO. The MISO transactions are grouped together, resulting in a net supply to or net purchase from MISO for each hour of each day. The net supply to MISO is recorded as bulk power sales in “Electric utility revenues” and the net purchase from MISO is recorded in “Electric production fuel and purchased power” in the income statements.
Non-utility - Revenues from Alliant Energy’s non-utility businesses are primarily from its Transportation business and are recognized over time as services are rendered or goods are delivered to customers.
12 |
Taxes Collected from Customers - Sales or various other taxes collected by certain of Alliant Energy’s subsidiaries on behalf of other agencies are recorded on a net basis and are not included in revenues.
Other - Alliant Energy, IPL and WPL do not disclose the value of unsatisfied performance obligations for: (i) contracts with an original expected length of one year or less; and (ii) contracts for which revenue is recognized at the amount to which they have the right to invoice for goods delivered or services performed.
NOTE 1(d) New Accounting Standards -
Revenue Recognition - In May 2014, the Financial Accounting Standards Board issued an accounting standard providing principles for recognizing revenue for the transfer of promised goods or services to customers with the consideration to which the entity expects to be entitled in exchange for those goods or services. Alliant Energy, IPL and WPL adopted this standard on January 1, 2018 using the modified retrospective method of adoption, which was applied to contracts with customers that were completed subsequent to January 1, 2018. Alliant Energy, IPL and WPL utilized a portfolio approach upon adoption, which involved evaluating portfolios of contracts with similar characteristics, where the effects of applying the standard were not expected to be materially different than evaluating on an individual contract basis. Upon adoption, there were no cumulative effect adjustments made to the January 1, 2018 retained earnings balances. In addition, prior period amounts have not been restated to reflect the adoption of this standard and continue to be reported under the accounting standards in effect for those periods. Alliant Energy, IPL and WPL did not have a material change in revenue recognition, including the timing and pattern of revenue recognition, as a result of the adoption of this standard. Refer to Notes 1(c) and 8 for further discussion of revenue recognition.
Leases - In February 2016, the Financial Accounting Standards Board issued an accounting standard requiring lease assets and lease liabilities, including operating leases, to be recognized on the balance sheet for all leases with terms longer than 12 months. The standard also requires disclosure of key information about leasing arrangements. Alliant Energy, IPL and WPL will adopt this standard on January 1, 2019 using the modified retrospective method of adoption, which requires cumulative effect adjustments to the balance sheets on January 1, 2019 upon adoption. Prior period amounts will continue to be reported under the accounting standards in effect for those periods. Alliant Energy, IPL and WPL currently plan to elect the land easement transition practical expedient, for which existing land easements that were not previously accounted for as leases under the original accounting standards do not need to be evaluated under the new accounting standard. In addition, Alliant Energy, IPL and WPL evaluated land easements that were previously accounted for as leases and determined that the majority of these land easements relate to joint-use land sites, and do not currently expect them to meet the criteria for leases under the new accounting standard. Therefore, these land easement arrangements will no longer be reflected as operating leases effective January 1, 2019. Alliant Energy, IPL and WPL will continue to evaluate the impact of this standard and do not currently expect a material change to their financial condition or results of operations as a result of adopting the new lease accounting standard.
Presentation of Net Periodic Pension and Postretirement Benefit Costs - In March 2017, the Financial Accounting Standards Board issued an accounting standard amending the income statement presentation of the components of net periodic benefit costs for defined benefit pension and other postretirement plans. The standard requires entities to (1) disaggregate the current service cost component from the other components of net periodic benefit costs and present it with other employee compensation costs in the income statement; and (2) include the other components in the income statement outside of operating income. Only the service cost component of net periodic benefit costs is eligible for capitalization into property, plant and equipment; however, IPL and WPL, as rate-regulated entities, capitalize the other components of net periodic benefit costs into regulatory assets or regulatory liabilities. Alliant Energy, IPL and WPL adopted this standard on January 1, 2018 and used the retrospective method of adoption for the presentation requirements and prospective method of adoption for the capitalization requirements. Alliant Energy, IPL and WPL used the actual net periodic benefit costs adjusted for approximately 40% of net periodic benefit costs allocated to capital projects for the retrospective method of adoption for the presentation requirements. The change in presentation resulted in a decrease in “Other operation and maintenance” expenses and an increase in “Other (income) and deductions” in Alliant Energy’s, IPL’s and WPL’s income statements of $4.8 million, $2.0 million and $2.8 million for the three months ended September 30, 2017, and $13.5 million, $5.5 million and $7.9 million for the nine months ended September 30, 2017, respectively.
Cash Flows Statements - In August 2016, the Financial Accounting Standards Board issued an accounting standard providing specific guidance on several cash flow classification matters. The accounting standard requires classification of the consideration received for the beneficial interest obtained for transferring accounts receivable from IPL’s sales of accounts receivable program as an investing activity, instead of an operating activity. Alliant Energy, IPL and WPL retrospectively adopted this standard on January 1, 2018, and use a method of presentation that allocates cash flows between operating and investing activities based on daily transactional activity. For the nine months ended September 30, 2017, Alliant Energy and
13 |
IPL reclassified $432.1 million of the related cash received from IPL’s sales of accounts receivable program from operating activities to investing activities based on daily transactional activity. The related impact on Alliant Energy’s and IPL’s cash flows statements for the year ended December 31, 2017 was $461.8 million. For the three months ended March 31, 2018 and the six months ended June 30, 2018, Alliant Energy, IPL and WPL utilized a method of presentation that allocated cash flows between operating and investing activities based on monthly transactional activity. The change in method of presentation to daily transactional activity increases Alliant Energy’s operating cash flows to $156.3 million and $274.4 million, and IPL’s operating cash flows to $1.8 million and $12.8 million, for the three months ended March 31, 2018 and six months ended June 30, 2018, respectively. The change in method of presentation to daily transactional activity increases Alliant Energy’s operating cash flows to $173.5 million and $249.8 million, and IPL’s operating cash flows to $16.1 million and $15.8 million, for the three months ended March 31, 2017 and six months ended June 30, 2017, respectively.
In November 2016, the Financial Accounting Standards Board issued an accounting standard requiring restricted cash to be included within beginning-of-period and end-of-period cash and cash equivalents in the cash flows statements. Alliant Energy, IPL and WPL adopted this standard on January 1, 2018, which was applied retrospectively. Refer to Note 1(b) for further discussion of restricted cash.

Tax-related - During the nine months ended September 30, 2018, Alliant Energy’s and IPL’s tax-related regulatory assets increased primarily due to property-related differences for qualifying repairs expenditures. Alliant Energy’s and IPL’s tax-related regulatory assets are generally impacted by certain property-related differences at IPL for which deferred tax is not recorded in the income statement pursuant to Iowa rate-making principles. Deferred tax amounts for such property-related differences at IPL are recorded to regulatory assets, along with the necessary revenue requirement tax gross-ups.
Partially offsetting the increase to tax-related regulatory assets from property-related differences discussed above was a decrease due to the impacts of Iowa tax reform. In May 2018, Iowa tax reform was enacted, resulting in a reduction in the Iowa income tax rate from 12% to 9.8%, effective January 1, 2021 and the elimination of the deduction for federal income taxes, effective January 1, 2022. Alliant Energy’s and IPL’s deferred tax assets and liabilities as of June 30, 2018 were remeasured based upon the new tax rate. Alliant Energy and IPL recorded the net changes from remeasuring deferred tax assets and liabilities as a change in regulatory assets or regulatory liabilities. During the nine months ended September 30, 2018, as a result of Iowa tax reform, Alliant Energy’s and IPL’s tax-related regulatory assets decreased $33.7 million and tax-related regulatory liabilities increased $7.3 million.

Electric generating units retired early - In June 2018, IPL retired the natural gas-fired M.L. Kapp Generating Station and reclassified the remaining net book value of this EGU from property, plant and equipment to a regulatory asset on Alliant Energy’s and IPL’s balance sheets. The remaining net book value, which was $29 million as of September 30, 2018, is currently included in IPL’s rate base and IPL is earning a return of and a return on the outstanding balance. IPL expects continued recovery of the remaining net book value to be addressed in a future rate review.
In September 2018, WPL retired the coal-fired Edgewater Unit 4 and reclassified the remaining net book value of this EGU from property, plant and equipment to a regulatory asset on Alliant Energy’s and WPL’s balance sheets. The remaining net book value, which was $24 million as of September 30, 2018, is currently included in WPL’s rate base and WPL is earning a return of and a return on the outstanding balance. WPL will continue to recover the remaining net book value of this EGU from both its retail and wholesale customers over a 10-year period beginning January 1, 2019 pursuant to PSCW and FERC orders.
Other - In January 2018, the IUB issued an order requiring IPL and other investor-owned utilities in Iowa to track all calculated differences since January 1, 2018 resulting from Federal Tax Reform, such that any over-collections can be refunded to its customers at a future date. Pursuant to IUB approval, the retail electric portion of IPL’s Federal Tax Reform benefits is currently being refunded to customers, beginning May 2018. In January 2018, the PSCW issued an order directing WPL and other investor-owned utilities in Wisconsin to defer the revenue requirement impacts resulting from Federal Tax Reform since its inception. Pursuant to PSCW approval, the retail electric and gas portions of WPL’s Federal Tax Reform benefits are currently being refunded to customers, beginning June 2018. Alliant Energy, IPL, and WPL refunded Federal Tax Reform benefits of $20 million, $9 million and $11 million for the three months ended September 30, 2018, and $47 million, $16 million and $31 million for the nine months ended September 30, 2018, respectively, which were recorded as a reduction in revenues. As of September 30, 2018, Alliant Energy’s, IPL’s and WPL’s remaining deferrals related to Federal Tax Reform were $22 million, $19 million and $3 million, respectively, which are included in “Other” in the regulatory liabilities table above.
In December 2016, WPL received an order from the PSCW related to its retail electric and gas rate review for the 2017/2018 Test Period. The order included provisions that require WPL to defer a portion of its earnings if its annual regulatory return on common equity exceeds certain levels in 2018. As of September 30, 2018, Alliant Energy and WPL deferred $12 million of WPL’s 2018 earnings related to this provision, which is included in “Other” in the regulatory liabilities table above.
Utility Rate Reviews -
IPL’s Retail Gas Rate Review (2017 Test Year) - In May 2018, IPL filed a request with the IUB to increase annual gas base rates for its Iowa retail gas customers by $20 million, or approximately 8%. The request was based on a 2017 historical Test Year as adjusted for certain known and measurable changes occurring up to 12 months after the commencement of the proceeding. The key drivers for the filing included recovery of capital projects, partially offset by the benefits of Federal Tax Reform. An interim retail gas rate increase of $11 million, or approximately 5%, on an annual basis, was implemented effective May 14, 2018. The interim rate increase does not require regulatory approval; however, it will be subject to refund pending determination of final rates. In September 2018, IPL and parties to the proceeding filed a unanimous settlement agreement with the IUB, proposing an annual retail gas base rate increase of $14 million, or approximately 6%. IPL currently expects a final decision from the IUB in 2018 with final rates effective by late 2018 or the first quarter of 2019. The IUB must issue a decision on requests for retail rate changes within 10 months from the date the application is filed.
IPL’s Retail Electric Rate Review (2016 Test Year) - In April 2017, IPL filed a request with the IUB to increase annual electric base rates for its Iowa retail electric customers. An interim retail electric base rate increase of $102 million, or approximately 7%, on an annual basis, was implemented effective April 13, 2017. In September 2017, IPL reached a settlement agreement with intervener groups for an annual electric base rate increase of $130 million, or approximately 9%. In February 2018, the IUB issued an order approving the settlement. Final rates were effective May 1, 2018.
WPL’s Retail Electric and Gas Rate Review (2019/2020 Test Period) - In September 2018, the PSCW issued an order approving WPL’s proposed settlement for its retail electric and gas rate review covering the 2019/2020 Test Period, which was based on a stipulated agreement between WPL and intervener groups. Under the settlement, WPL retail electric and gas base rates will not change from current levels through the end of 2020.

NOTE 3. PROPERTY, PLANT AND EQUIPMENT
Utility -
Natural Gas-Fired Generation Project -
WPL’s West Riverside Energy Center - WPL is currently constructing West Riverside, an approximate 730 MW natural gas-fired combined-cycle EGU. Construction began in 2016 and is currently expected to be completed by the end of 2019. As of September 30, 2018, Alliant Energy and WPL recorded capitalized expenditures of $438 million and AFUDC of $35 million for West Riverside in “Property, plant and equipment, net” on their balance sheets. These capital expenditures reflect WPL’s portion of West Riverside. Certain electric cooperatives, which currently have wholesale power supply agreements with WPL, acquired approximately 60 MW of West Riverside in January 2018, and are funding their share of capital expenditures during construction. As part of the electric cooperatives’ acquisitions, the current wholesale power supply agreements with the various electric cooperatives were extended by at least four years until 2026 with automatic continuation of such agreements unless terminated by either party, with a five-year notice requirement.
Wind Generation -
IPL’s Expansion of Wind Generation - IPL currently plans to add up to 1,000 MW of new wind generation to its existing generation portfolio. These wind projects are expected to be placed into service in 2019 and 2020. As of September 30, 2018, Alliant Energy and IPL recorded capitalized expenditures of $645 million and AFUDC of $33 million for this expansion of wind generation in “Property, plant and equipment, net” on their balance sheets.
WPL’s Acquisition of Forward Wind Energy Center (FWEC) - In January 2018 and March 2018, WPL received approval from FERC and the PSCW, respectively, to acquire a partial ownership interest in the assets of FWEC, which is a 129 MW wind farm located in Wisconsin. In April 2018, WPL acquired 55 MW of the FWEC wind farm for approximately $74 million. As of the closing date, the estimated fair value of the assets purchased and the liabilities assumed by WPL were as follows (in millions):

NOTE 4. RECEIVABLES
Sales of Accounts Receivable - IPL maintains a Receivables Purchase and Sale Agreement (Receivables Agreement) whereby it may sell its customer accounts receivables, unbilled revenues and certain other accounts receivables to a third party through wholly-owned and consolidated special purpose entities. In March 2018, IPL amended and extended through March 2021 the purchase commitment from the third party to which it sells its receivables. Effective April 2018, the limit on cash proceeds fluctuates between $90 million and $110 million. The transfers of receivables meet the criteria for sale accounting established by the transfer of financial assets accounting rules. As of September 30, 2018, IPL had $109.0 million of available capacity under its sales of accounts receivable program. For the three and nine months ended September 30, 2018 and 2017, IPL’s costs incurred related to the sales of accounts receivable program were not material.
IPL’s maximum and average outstanding cash proceeds (based on daily outstanding balances) related to the sales of accounts receivable program for the three and nine months ended September 30 were as follows (in millions):

Non-utility Wind Farm in Oklahoma - Alliant Energy’s interest in a non-utility wind farm in Oklahoma commenced in July 2017. As a result, there was no corresponding equity income recognized during the first half of 2017. The equity income recognized during the nine months ended September 30, 2018 was primarily related to the impacts of Federal Tax Reform. The liquidation method utilized to recognize Alliant Energy’s share of the wind farm’s earnings includes utilizing the federal income tax rate in effect as of the end of the measurement period. The lower federal income tax rate effective as of January 1, 2018 resulted in an acceleration of earnings attributable to Alliant Energy’s interest in the Oklahoma wind farm. This increase in earnings is expected to reverse over time.
NOTE 6. COMMON EQUITY
Common Share Activity - A summary of Alliant Energy’s common stock activity was as follows:
Shares outstanding, January 1, 2018 | 231,348,646 | |

At-the-market Offering Program - In May 2018, Alliant Energy filed a prospectus supplement under which it may sell up to $175 million of its common stock through an at-the-market offering program. As of September 30, 2018, Alliant Energy issued 4,171,013 shares of common stock through this program and received cash proceeds of $173 million, net of $2 million in fees and commissions. The proceeds from the issuances of common stock were used for general corporate purposes. Alliant Energy currently has no plans to issue any additional common stock through this at-the-market offering program.
Comprehensive Income - For the three and nine months ended September 30, 2018 and 2017, Alliant Energy’s other comprehensive income was not material; therefore, its comprehensive income was substantially equal to its net income and its comprehensive income attributable to Alliant Energy common shareowners was substantially equal to its net income attributable to Alliant Energy common shareowners for such periods. For the three and nine months ended September 30, 2018 and 2017, IPL and WPL had no other comprehensive income; therefore, their comprehensive income was equal to their net income and their comprehensive income available for common stock was equal to their earnings available for common stock for such periods.

As discussed in Note 7(b), in June 2018, AEF retired its $95 million term loan credit agreement expiring in 2018.
NOTE 7(b) Long-term Debt - In April 2018, AEF entered into a $300 million variable-rate (2.8% at September 30, 2018) term loan credit agreement (with Alliant Energy as guarantor) and used the proceeds from borrowings under this agreement for general corporate purposes. AEF’s term loan credit agreement expires in April 2020 and includes substantially the same financial covenants that are included in Alliant Energy’s credit facility agreement.
In June 2018, AEF (with Alliant Energy as guarantor) issued $400 million of 3.75% senior notes due 2023 and $300 million of 4.25% senior notes due 2028. The proceeds from the issuances were used by AEF to retire its $500 million and $95 million variable-rate term loan credit agreements expiring in 2018, to reduce Alliant Energy’s outstanding commercial paper and for general corporate purposes.
In September 2018, IPL issued $500 million of 4.1% senior debentures due 2028. The senior debentures were issued as green bonds, and all of the net proceeds were allocated for the construction and development of wind and solar projects. In September 2018 and October 2018, IPL retired its $100 million (5.875%) and $250 million (7.25%) senior debentures, respectively.
NOTE 8. REVENUES
Revenues from Alliant Energy’s, IPL’s and WPL’s utility businesses are primarily from electric and gas sales provided to customers based on approved tariffs or specific contracts with customers. IPL’s and WPL’s primary performance obligations under such arrangements are to deliver electricity and gas, and their customers simultaneously receive and consume the electricity and gas. For such arrangements, revenues are recognized equivalent to the value of the electricity or gas supplied during each period, including amounts billed during each period and changes in amounts estimated to be billed at the end of each period. IPL and WPL apply the right to invoice method to measure progress towards completing performance obligations to transfer electricity and gas to their customers.
IPL provides retail electric and gas service to customers in Iowa, and WPL provides retail and wholesale electric and retail gas service to customers in Wisconsin. IPL also sells electricity to wholesale customers in Minnesota, Illinois and Iowa, as well as steam from its Prairie Creek Generating Station to high-pressure steam customers in Iowa.
IPL’s and WPL’s retail electric and gas revenues include sales to residential, commercial and industrial customers. IPL’s and WPL’s retail electric and gas customer prices are based on IPL’s and WPL’s cost of service and are determined through general rate review proceedings and various tariff filings with the IUB and PSCW, respectively. Such tariff-based services provide electricity or gas to customers without a defined contractual term.
IPL and WPL have wholesale electric market-based rate authority from FERC allowing them to participate in wholesale energy markets (e.g. MISO) and transact directly with third parties. This authority from FERC allows sales of electricity referred to as bulk power sales based on current market values. FERC also allows IPL and WPL to enter into power supply agreements with municipalities and rural electric cooperatives with defined contractual terms, which include standard pricing mechanisms that are detailed in current tariffs accepted by FERC through wholesale rate review proceedings.
18 |
Revenues from Alliant Energy’s non-utility business customers are primarily from its Transportation business, which includes a short-line railway that provides freight service between Cedar Rapids, Iowa and Iowa City, Iowa; a barge terminal and hauling services on the Mississippi River; and other transfer and storage services.
As of September 30, 2018, revenue expected to be recognized in any future year related to remaining performance obligations is not material, as the majority of revenues are recognized as services are rendered or commodities are delivered, and are from contracts with durations of less than one year. Alliant Energy, IPL and WPL do not have any material contract assets or contract liabilities, or contract acquisition fulfillment costs.
Disaggregation of revenues from contracts with customers, which correlates to revenues for each reportable segment, was as follows (in millions):

Federal Tax Reform Adjustments - In December 2017, Federal Tax Reform was enacted, which had a material impact on Alliant Energy’s, IPL’s and WPL’s financial statements in the fourth quarter of 2017 since changes in tax laws must be recognized in the period in which the law was enacted. During the third quarter of 2018, additional rules were issued, including clarifications of the treatment of bonus depreciation deductions, which impacted the federal income tax return for the calendar year 2017. As result of these clarifying rules, Alliant Energy, IPL and WPL recorded tax benefits of $5.6 million, $1.1 million and $5.5 million, respectively, in the third quarter of 2018.

Deferred Tax Assets and Liabilities - For the nine months ended September 30, 2018, Alliant Energy’s, IPL’s and WPL’s deferred tax liabilities increased $96.8 million, $22.3 million and $57.2 million, respectively. The increases were primarily due to property-related differences, which were partially offset by increases in federal credit carryforwards. Alliant Energy’s and IPL’s increases were also partially offset by the effects of Iowa tax reform, which is discussed in Note 2. WPL’s increase was also partially due to the utilization of federal net operating losses.
Carryforwards - At September 30, 2018, carryforwards and expiration dates were estimated as follows (in millions):

Financial Statement Presentation - Derivative instruments are recorded at fair value each reporting date on the balance sheets as assets or liabilities. The fair values of current derivative assets are included in “Other current assets,” non-current derivative assets are included in “Deferred charges and other,” current derivative liabilities are included in “Other current liabilities” and non-current derivative liabilities are included in “Other liabilities” on the balance sheets as follows (in millions):

Non-current derivative liabilities | 14.8 | 23.0 | 6.5 | 14.4 | 8.3 | 8.6 |
Credit Risk-related Contingent Features - Various agreements contain credit risk-related contingent features, including requirements to maintain certain credit ratings and/or limitations on liability positions under the agreements based on credit ratings. Certain of these agreements with credit risk-related contingency features are accounted for as derivative instruments. In the event of a material change in creditworthiness or if liability positions exceed certain contractual limits, credit support may need to be provided in the form of letters of credit or cash collateral up to the amount of exposure under the contracts, or the contracts may need to be unwound and underlying liability positions paid. At September 30, 2018 and December 31, 2017, the aggregate fair value of all derivative instruments with credit risk-related contingent features in a net liability position was not materially different than amounts that would be required to be posted as credit support to counterparties by Alliant Energy, IPL or WPL if the most restrictive credit risk-related contingent features for derivative agreements in a net liability position were triggered.
Balance Sheet Offsetting - The fair value amounts of derivative instruments subject to a master netting arrangement are not netted by counterparty on the balance sheets. However, if the fair value amounts of derivative instruments by counterparty were netted, amounts would not be materially different from gross amounts of derivative assets and derivative liabilities at September 30, 2018 and December 31, 2017. Fair value amounts recognized for the right to reclaim cash collateral (receivable) or the obligation to return cash collateral (payable) are not offset against fair value amounts recognized for derivative instruments executed with the same counterparty under the same master netting arrangement.
NOTE 13. COMMITMENTS AND CONTINGENCIES
NOTE 13(a) Capital Purchase Obligations - Various contractual obligations contain minimum future commitments related to capital expenditures for certain construction projects. IPL’s projects include the expansion of wind generation and installation of an SCR system at Ottumwa Unit 1 to reduce NOx emissions at the EGU. WPL’s projects include West Riverside. At September 30, 2018, Alliant Energy’s, IPL’s and WPL’s minimum future commitments related to certain contractual obligations for these projects were $82 million, $26 million and $56 million, respectively.
NOTE 13(b) Other Purchase Obligations - Various commodity supply, transportation and storage contracts help meet obligations to provide electricity and natural gas to utility customers. In addition, there are various purchase obligations associated with other goods and services. At September 30, 2018, minimum future commitments related to these purchase obligations were as follows (in millions):

In July 2018, IPL entered into an amendment to shorten the term of the DAEC PPA by five years in exchange for a $110 million buyout payment by IPL in September 2020, which is not included in Alliant Energy’s and IPL’s amounts. The amendment to the DAEC PPA is contingent upon IUB approval of IPL’s July 2018 application regarding recovery of the buyout payment. |
(b) | Corporate Services entered into system-wide coal contracts on behalf of IPL and WPL that include minimum future commitments. These commitments were assigned to IPL and WPL based on information available as of September 30, 2018 regarding expected future usage, which is subject to change. |
(c) | Includes individual commitments incurred during the normal course of business that exceeded $1 million at September 30, 2018. |

NOTE 13(c) Guarantees and Indemnifications -
Whiting Petroleum - In 2004, Alliant Energy sold its remaining interest in Whiting Petroleum. Whiting Petroleum is an independent oil and gas company. Alliant Energy Resources, LLC, as the successor to a predecessor entity that owned Whiting Petroleum, and a wholly-owned subsidiary of AEF, continues to guarantee the partnership obligations of an affiliate of Whiting Petroleum under general partnership agreements in the oil and gas industry, including with respect to the future abandonment of certain platforms off the coast of California and related onshore plant and equipment owned by the partnerships. The guarantees do not include a maximum limit. As of September 30, 2018, the present value of the abandonment obligations is estimated at $36 million. Alliant Energy is not aware of any material liabilities related to these guarantees of which it is probable that Alliant Energy Resources, LLC will be obligated to pay and therefore has not recognized any material liabilities related to this guarantee as of September 30, 2018.
Non-utility Wind Farm in Oklahoma - In July 2017, a wholly-owned subsidiary of AEF acquired a cash equity ownership interest in a non-utility wind farm located in Oklahoma. The wind farm provides electricity to a third-party under a long-term PPA. Alliant Energy provided a parent guarantee of its subsidiary’s indemnification obligations under the related operating agreement and PPA. Alliant Energy’s obligations under the operating agreement were $90 million as of September 30, 2018 and will reduce annually until expiring in July 2047. Alliant Energy’s obligations under the PPA are subject to a maximum limit of $17 million and expire in December 2031, subject to potential extension. Alliant Energy is not aware of any material liabilities related to this guarantee that it is probable that it will be obligated to pay and therefore has not recognized any material liabilities related to this guarantee as of September 30, 2018.
IPL’s Minnesota Electric Distribution Assets - IPL provided indemnifications associated with the July 2015 sale of its Minnesota electric distribution assets for losses resulting from potential breach of IPL’s representations, warranties and obligations under the sale agreement. Alliant Energy and IPL believe the likelihood of having to make any material cash payments under these indemnifications is remote. IPL has not recorded any material liabilities related to these indemnifications as of September 30, 2018. The general terms of the indemnifications provided by IPL included a maximum limit of $17 million and expire in October 2020.
NOTE 13(d) Environmental Matters -
Manufactured Gas Plant (MGP) Sites - IPL and WPL have current or previous ownership interests in various sites that are previously associated with the production of gas for which IPL and WPL have, or may have in the future, liability for investigation, remediation and monitoring costs. IPL and WPL are working pursuant to the requirements of various federal and state agencies to investigate, mitigate, prevent and remediate, where necessary, the environmental impacts to property, including natural resources, at and around these former MGP sites in order to protect public health and the environment. At September 30, 2018, estimated future costs expected to be incurred for the investigation, remediation and monitoring of the MGP sites, as well as environmental liabilities recorded on the balance sheets for these sites, which are not discounted, were as follows (in millions). At September 30, 2018, such amounts for WPL were not material.
Alliant Energy | IPL | ||||||||||
Range of estimated future costs | $11 | - | $29 | $9 | - | $25 | |||||
Current and non-current environmental liabilities | 16 | 13 |
WPL Consent Decree - In 2013, the U.S. District Court for the Western District of Wisconsin approved a Consent Decree that WPL, along with the other owners of Edgewater and Columbia, entered into with the EPA and the Sierra Club, thereby resolving claims against WPL. Such claims included allegations that the owners of Edgewater, Nelson Dewey and Columbia violated the Prevention of Significant Deterioration program requirements, Title V Operating Permit requirements of the Clean Air Act (CAA) and the Wisconsin State Implementation Plan designed to implement the CAA.
WPL has completed various requirements under the Consent Decree. The Consent Decree also establishes sulfur dioxide (SO2), NOx and particulate matter emission rate limits for Columbia Units 1 and 2, and Edgewater Units 4 and 5. In addition, the Consent Decree includes annual plant-wide SO2 and NOx emission caps for Columbia and Edgewater. Alliant Energy and WPL currently expect to recover material costs incurred by WPL related to compliance with the terms of the Consent Decree from WPL’s electric customers.
IPL Consent Decree - In 2015, the U.S. District Court for the Northern District of Iowa approved a Consent Decree that IPL entered into with the EPA, the Sierra Club, the State of Iowa and Linn County in Iowa, thereby resolving potential CAA issues associated with emissions from IPL’s coal-fired generating facilities in Iowa. IPL has completed various requirements under the Consent Decree. IPL’s remaining requirements include installing an SCR system or equivalent NOx reduction system at Ottumwa by December 31, 2019, and fuel switching or retiring Burlington by December 31, 2021 and Prairie Creek Units 1 and 3 by December 31, 2025.
27 |
The Consent Decree also establishes SO2, NOx and particulate matter emission rate limits with varying averaging times for Burlington, Lansing, M.L. Kapp, Ottumwa and Prairie Creek. In addition, the Consent Decree includes calendar-year SO2 and NOx emission caps for Prairie Creek, and calendar-year SO2 and NOx emission caps in aggregate for Burlington, Lansing, M.L. Kapp, Ottumwa and Prairie Creek. Alliant Energy and IPL currently expect to recover material costs incurred by IPL related to compliance with the terms of the Consent Decree from IPL’s electric customers.
Other Environmental Contingencies - In addition to the environmental liabilities discussed above, various environmental rules are monitored that may have a significant impact on future operations. Several of these environmental rules are subject to legal challenges, reconsideration and/or other uncertainties. Given uncertainties regarding the outcome, timing and compliance plans for these environmental matters, the complete financial impact of each of these rules is not able to be determined; however future capital investments and/or modifications to EGUs to comply with certain of these rules could be significant. Specific current, proposed or potential environmental matters include, among others: Cross-State Air Pollution Rule, Effluent Limitation Guidelines, Coal Combustion Residuals Rule, and various legislation and EPA regulations to monitor and regulate the emission of greenhouse gases, including carbon emissions from new (CAA Section 111(b)) and existing (CAA Section 111(d)) fossil-fueled EGUs.
NOTE 14. SEGMENTS OF BUSINESS
In the fourth quarter of 2017, Alliant Energy and WPL modified the segment reporting related to ATC Holdings, consistent with information used by their chief operating decision maker to evaluate performance and allocate resources. As of December 31, 2017, ATC Holdings are no longer included in Alliant Energy’s utility electric operations reportable segment or WPL’s electric operations reportable segment. As a result, all prior period amounts impacted by this change were reclassified to conform to the new presentation. Alliant Energy’s related amounts were reclassified from “Electric Utility” to “ATC Holdings, Non-Utility, Parent and Other” in the table below. There was no resulting change to WPL’s segment reporting for the three and nine months ended September 30, 2017.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
This MDA includes information relating to Alliant Energy, and IPL and WPL (collectively, the Utilities), as well as ATC Holdings, AEF and Corporate Services. Where appropriate, information relating to a specific entity has been segregated and labeled as such. The following discussion and analysis should be read in conjunction with the Financial Statements and the Notes included in this report, as well as the financial statements, notes and MDA included in the 2017 Form 10-K. Unless otherwise noted, all “per share” references in MDA refer to earnings per diluted share.
RESULTS OF OPERATIONS
Overview - Alliant Energy’s net income and earnings per weighted average common share (EPS) attributable to Alliant Energy common shareowners for the third quarter were as follows (dollars in millions, except per share amounts):
2018 | 2017 | ||||||||||||||
Income (Loss) | EPS | Income (Loss) | EPS | ||||||||||||
Utilities and Corporate Services | $206.3 | $0.88 | $173.6 | $0.75 | |||||||||||
ATC Holdings | 6.3 | 0.03 | 6.1 | 0.03 | |||||||||||
Non-utility and Parent | (7.1 | ) | (0.04 | ) | (10.9 | ) | (0.05 | ) | |||||||
Alliant Energy Consolidated | $205.5 | $0.87 | $168.8 | $0.73 |
The table above includes EPS for Utilities and Corporate Services, ATC Holdings, and Non-utility and Parent, which are non-GAAP financial measures. Alliant Energy believes these non-GAAP financial measures are useful to investors because they facilitate an understanding of segment performance and trends, and provide additional information about Alliant Energy’s operations on a basis consistent with the measures that management uses to manage its operations and evaluate its performance.
Alliant Energy’s, IPL’s and WPL’s net income increased by $37 million, $6 million and $27 million, respectively, for the three-month period. Alliant Energy’s increase was primarily due to higher retail electric sales due to warmer temperatures in the third quarter of 2018 compared to the same period in 2017, higher margins resulting from IPL’s and WPL’s increasing rate base, and higher AFUDC. These items were partially offset by higher depreciation expense. Additional earnings details for the three and nine months ended September 30, 2018 and 2017 are discussed below.
Results of operations include financial information prepared in accordance with GAAP as well as utility electric margins and utility gas margins, which are not measures of financial performance under GAAP. Utility electric margins are defined as electric revenues less electric production fuel, purchased power and electric transmission service expenses. Utility gas margins are defined as gas revenues less cost of gas sold. Utility electric margins and utility gas margins are non-GAAP financial measures because they exclude other utility and non-utility revenues, other operation and maintenance expenses, depreciation and amortization expenses, and taxes other than income tax expense.
Management believes that utility electric and gas margins provide a meaningful basis for evaluating and managing utility operations since electric production fuel, purchased power and electric transmission service expenses and cost of gas sold are generally passed through to customers, and therefore, result in changes to electric and gas revenues that are comparable to changes in such expenses. The presentation of utility electric and gas margins herein is intended to provide supplemental information for investors regarding operating performance. These utility electric and gas margins may not be comparable to how other entities define utility electric and gas margin. Furthermore, these measures are not intended to replace operating income as determined in accordance with GAAP as an indicator of operating performance.

For the three and nine months ended September 30, operating income and a reconciliation of utility electric and gas margins to the most directly comparable GAAP measure, operating income, was as follows (in millions):

STRATEGIC OVERVIEW
The strategic overview summary included in the 2017 Form 10-K has not changed materially, except as described below.
Generation Plans -
Wind Generation - The strategic plan includes the planned development of up to 1,200 MW of wind generation in aggregate (up to 1,000 MW at IPL and up to 200 MW at WPL).
IPL’s Expansion of Wind Generation - In April 2018, IPL received approval from the IUB for advance rate-making principles for up to 500 MW of new wind generation, which is in addition to the 500 MW of new wind generation approved by the IUB in October 2016. The April 2018 IUB decision approved IPL’s requested advance rate-making principles, except for the return on common equity for the calculation of AFUDC during the construction period, of which the IUB approved a return of 9.6%.
IPL currently has on-going, new wind generation development of up to 1,000 MW utilizing the following wind sites:
Wind Site | Nameplate Capacity | Expected In-service Date | Location | |||
Upland Prairie | Up to 300 MW | 2019 | Clay and Dickinson Counties, Iowa | |||
English Farms | Up to 170 MW | 2019 | Poweshiek County, Iowa | |||
Golden Plains | Up to 200 MW | 2020 | Winnebago and Kossuth Counties, Iowa | |||
Whispering Willow Expansion | Up to 200 MW | 2020 | Franklin County, Iowa | |||
Richland | Up to 130 MW | 2020 | Sac County, Iowa |
35 |
WPL’s Expansion of Wind Generation - In May 2018, WPL filed for approval from the PSCW to own up to 150 MW of new wind generation in Kossuth County, Iowa. WPL has entered into an agreement to purchase the wind farm after development is complete, pending approval from the PSCW, which is currently expected in early 2019. If approved, construction is currently expected to start in summer 2019 and the wind farm is currently expected to be placed in service in 2020.
Refer to Note 3 for discussion of WPL’s April 2018 acquisition of 55 MW of the Forward Wind Energy Center.
Coal-Fired Generation -
Plant Retirements - Refer to Note 2 for discussion of the 2018 retirements of IPL’s M.L. Kapp Unit 2 and WPL’s Edgewater Unit 4.
RATE MATTERS
The rate matters summary included in the 2017 Form 10-K has not changed materially, except as described below.
Retail Base Rate Filings -
WPL’s Retail Electric and Gas Rate Review (2019/2020 Test Period) - In September 2018, WPL received an order from the PSCW approving WPL’s proposed settlement for its retail electric and gas rate review covering the 2019/2020 Test Period, which was based on a stipulated agreement between WPL and intervener groups. Under the settlement, WPL retail electric and gas base rates will not change from current levels through the end of 2020. Retail electric revenue requirements resulting from increasing investments in rate base (including West Riverside) are being offset by lower fuel-related costs and Federal Tax Reform refunds. Retail gas revenue requirements resulting from increasing investments in rate base are being offset by Federal Tax Reform refunds. The PSCW will issue a final order upon completion of its review of WPL’s anticipated fuel-related costs for 2019, which is currently expected in December 2018. Any changes granted from this decision will be effective January 1, 2019. The fuel-related cost component of WPL’s retail electric rates for 2020 will be addressed in a separate filing, which is currently expected to occur in the second or third quarter of 2019.
WPL’s settlement maintains the currently authorized return on common equity (ROE) of 10.0% and extends, with certain modifications, an earnings sharing mechanism through 2020. Under the earnings sharing mechanism, WPL will defer a portion of its earnings if its annual regulatory ROE exceeds 10.25% during the 2019/2020 Test Period. WPL must defer 50% of its excess earnings between 10.25% and 10.75%, and 100% of any excess earnings above 10.75%. The settlement was calculated based on the following key assumptions (Common Equity (CE); Long-term Debt (LD); Short-term Debt (SD); Weighted-average Cost of Capital (WACC); Net Investment Rate Base (NIRB)):
Utility | Test | Regulatory Capital Structure | After-tax | Return on | Average Rate Base | |||||||||||
Type | Period | CE | LD | SD | WACC | NIRB (a) | (in millions) (b) | |||||||||
Electric | 2019 | 52.6% | 43.5% | 3.9% | 7.47% | 6.95% | $3,507 | |||||||||
Electric | 2020 | 52.5% | 43.8% | 3.7% | 7.44% | 7.08% | 3,955 | |||||||||
Gas | 2019 | 52.6% | 43.5% | 3.9% | 7.47% | 6.84% | 363 | |||||||||
Gas | 2020 | 52.5% | 43.8% | 3.7% | 7.44% | 6.97% | 387 |
(a) | Return on NIRB includes an adjustment to the after-tax WACC to account for working capital, including impacts from Federal Tax Reform reclassifications of excess deferred taxes. |
(b) | Average rate base amounts reflect WPL’s allocated retail share of rate base and do not include construction work in progress or a cash working capital allowance, and were calculated using a forecasted 13-month average for the test periods. The PSCW provides a return on selected construction work in progress and a cash working capital allowance by adjusting the percentage return on rate base. |
IPL’s Retail Gas Rate Review (2017 Test Year) - Refer to Note 2 for discussion of the request IPL filed with the IUB in May 2018 to increase annual gas base rates for its Iowa retail gas customers and the subsequent interim retail gas rate increase, which was implemented effective May 14, 2018.
IPL’s Retail Electric Rate Review (2016 Test Year) - Refer to Note 2 for discussion of IPL’s final annual retail electric rate increase for the 2016 Test Year, which was effective May 1, 2018.
Federal Tax Reform - In January 2018, the IUB issued an order requiring IPL and other investor-owned utilities in Iowa to track all calculated differences since January 1, 2018 resulting from Federal Tax Reform. In April 2018, the IUB issued an order on IPL’s electric and gas Federal Tax Reform proposals. The IUB order approved the return of approximately $35 million of estimated annual tax benefits for 2018 to IPL’s retail electric customers utilizing the tax benefit rider effective May
36 |
1, 2018. These benefits are subject to true-up. For the three and nine months ended September 30, 2018, $9 million and $16 million of tax benefits, respectively, were returned to IPL’s retail electric customers. The IUB order also approved the return of approximately $3 million of estimated annual tax benefits for 2018 to IPL’s retail gas customers utilizing interim rates implemented May 14, 2018 for IPL’s 2017 Test Year gas rate review. These benefits are subject to further review by the IUB. Lastly, the IUB order determined the excess deferred taxes resulting from the remeasurement of accumulated deferred income taxes caused by Federal Tax Reform (approximately $350 million revenue requirement) will be addressed in IPL’s current and future retail electric and gas rate reviews.
In January 2018, the PSCW issued an order directing WPL and other investor-owned utilities in Wisconsin to defer the revenue requirement impacts since January 1, 2018 resulting from Federal Tax Reform. In May 2018, the PSCW issued an order directing WPL to return annual tax benefits for 2018 to WPL’s retail electric and gas customers. WPL is refunding a total of $36 million and $4 million in 2018 to its retail electric and gas customers, respectively. The estimated tax benefits related to the first half of 2018 were provided as a one-time credit of $18 million and $2 million on WPL’s retail electric and gas customers’ June 2018 bills, respectively. Thereafter, WPL currently expects to provide a monthly refund equal to one-twelfth of the estimated annual tax benefits for 2018 to its retail electric and gas customers through the end of 2018. For the three and nine months ended September 30, 2018, $11 million and $31 million of tax benefits, respectively, were returned to WPL’s retail electric and gas customers. Excess deferred taxes from the remeasurement of accumulated deferred income taxes caused by Federal Tax Reform result in an approximate $460 million revenue requirement impact for WPL. Approximately $85 million of this amount would be used to maintain base rates from current levels through 2020, and the remainder will be addressed in WPL’s future retail electric and gas rate reviews.
In March 2018, FERC issued an order granting a waiver request filed in February 2018 by a group of MISO transmission owners, including ITC Midwest LLC and ATC, allowing transmission rates to be updated to reflect the impacts resulting from Federal Tax Reform. As a result, beginning in March 2018, amounts billed by ITC Midwest LLC and ATC decreased due to the impacts from Federal Tax Reform. IPL and WPL currently expect lower electric transmission service expense of approximately $35 million and $10 million, respectively, in 2018 due to Federal Tax Reform. IPL began providing the benefits of the lower transmission service expenses to its electric customers utilizing the transmission cost recovery mechanism effective May 1, 2018. WPL will defer any incremental benefits of the lower transmission service expenses from Federal Tax Reform until a future electric rate review. Based on IPL’s and WPL’s electric transmission cost recovery mechanisms, they currently do not expect that any changes to electric transmission service costs billed by ITC Midwest LLC and ATC, respectively, will have a material impact on their financial condition and results of operations.
Iowa Tax Reform - Refer to Note 2 for discussion of future changes to the Iowa state income tax rate due to Iowa tax reform enacted in May 2018 and the resulting impact on Alliant Energy’s and IPL’s financial statements.
Iowa Energy Legislation - In May 2018, Iowa enacted new energy-related legislation. The most significant provisions of the legislation for Alliant Energy and IPL include the option for energy providers to use a forward-looking test year instead of the current historical test year approach for electric and gas rate reviews, and adjustment of electric transmission service costs through a permanent transmission rider.
IPL’s Duane Arnold Energy Center Purchased Power Agreement - In 2012, IPL entered into a nuclear generation PPA for the purchase of approximately 430 MW of capacity and the resulting energy from DAEC for a term from February 2014 through December 2025. In July 2018, IPL entered into a proposed amendment to shorten the term of the DAEC PPA by five years in exchange for a $110 million buyout payment by IPL in September 2020, which would change Alliant Energy’s and IPL’s future commitments related to the DAEC PPA. To replace some of the energy and capacity from DAEC, IPL entered into four new PPAs with expected 20-year terms beginning in 2020 and 2021 for the purchase of approximately 340 MW of energy in aggregate from existing Iowa wind farms that are expected to be repowered. The amendment to shorten the term of the DAEC PPA and the four new wind PPAs are expected to provide significant energy cost savings to IPL customers.
In July 2018, IPL filed an application with the IUB for approval to recover the buyout payment from IPL’s retail customers over a five-year period at IPL’s pre-tax weighted-average cost of capital in effect at the time recovery commences. In October 2018, IPL reached a settlement agreement with the Iowa Office of Consumer Advocate, the Iowa Business Energy Coalition, the Large Energy Group and the Resale Power Group of Iowa in support of IPL’s application. Three of the four wind PPAs and the amendment to the DAEC PPA are contingent upon IUB approval of IPL’s application regarding the recovery of the buyout payment. IPL currently anticipates a decision from the IUB on its application in 2018.

• | Planned Utility Rate Review - IPL currently expects to make a retail rate filing in the first quarter of 2019 based on one or more future forecasted test periods for electric and gas rates. The key drivers for the anticipated filing include recovery of capital projects, including new wind generation, and ongoing operational costs. IPL expects to concurrently file for interim electric rates based on historical data for 2018 and certain known and measurable changes occurring in the first quarter of 2019. Those interim electric rates are expected to be effective in April 2019. |
2019 Forecast - In 2019, the following financing activities, and impacts to results of operations, are currently anticipated to occur:
• | Financing Plans - Alliant Energy currently expects to issue up to $400 million of common stock in 2019 through one or more offerings and its Shareowner Direct Plan. IPL and WPL currently expect to issue up to $600 million and $400 million of long-term debt securities in 2019, respectively. WPL has $250 million of long-term debt maturing in July 2019. |
• | Common Stock Dividends - Alliant Energy announced a 6% increase in its targeted 2019 annual common stock dividend to $1.42 per share, which is equivalent to a quarterly rate of $0.355 per share, beginning with the February 2019 dividend payment. The timing and amount of future dividends is subject to an approved dividend declaration from Alliant Energy’s Board of Directors, and is dependent upon earnings expectations, capital requirements, and general financial business conditions, among other factors. |

• | Utility Electric and Gas Margins - Alliant Energy, IPL and WPL currently expect an increase in electric and gas margins in 2019 compared to 2018 from earnings on increasing rate base for WPL’s retail electric and gas rate review (2019/2020 Test Period) and interim rates for IPL’s planned retail rate review. Refer to “Rate Matters” for further discussion. |
• | Depreciation and Amortization Expenses - Alliant Energy, IPL and WPL currently expect an increase in depreciation and amortization expenses in 2019 compared to 2018 due to property additions, including IPL’s expansion of wind generation and WPL’s West Riverside natural gas-fired EGU. |
• | Interest Expense - Alliant Energy currently expects interest expense to increase in 2019 compared to 2018 primarily due to financings completed in 2018 and planned in 2019 as discussed above. |
