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 “expect,” “anticipate,” “plan” 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 Corporation (Alliant Energy), Interstate Power and Light Company (IPL) and Wisconsin Power and Light Company (WPL) that could materially affect actual results include:

 

   

federal and state regulatory or governmental actions, including the impact of energy, tax, financial and health care legislation, and of regulatory agency orders;

 

   

IPL’s and WPL’s ability to obtain adequate and timely rate relief to allow for, among other things, the recovery of operating costs, fuel costs, transmission costs, deferred expenditures, capital expenditures, and remaining costs related to generating units that may be permanently closed, earning their authorized rates of return, and the payments to their parent of expected levels of dividends;

 

   

weather effects on results of utility operations;

 

   

the ability to continue cost controls and operational efficiencies;

 

   

the impact of IPL’s retail electric base rate freeze in Iowa through 2013;

 

   

the impact of WPL’s potential retail electric and gas rate freeze in Wisconsin through 2014;

 

   

the state of the economy in IPL’s and WPL’s service territories and resulting implications on sales, margins and ability to collect unpaid bills;

 

   

developments that adversely impact Alliant Energy’s, IPL’s and WPL’s ability to implement their strategic plans, including unanticipated issues with new emission control equipment for various coal-fired generating facilities of IPL and WPL, WPL’s purchase of the Riverside Energy Center (Riverside), IPL’s potential construction of a new natural gas-fired electric generating facility in Iowa, Alliant Energy Resources, LLC’s (Resources’) construction of and selling price of the electricity output from its new 100 megawatt (MW) wind project, and the potential decommissioning of certain generating facilities of IPL and WPL;

 

   

the impact of changes to government incentive elections for wind projects;

 

   

successful resolution of the pending challenge by interveners of the approval by the Public Service Commission of Wisconsin (PSCW) of WPL’s Bent Tree—Phase I wind project;

 

   

issues related to the availability of generating facilities and the supply and delivery of fuel and purchased electricity and the price thereof, including the ability to recover and to retain the recovery of purchased power, fuel and fuel-related costs through rates in a timely manner;

 

   

the impact that fuel and fuel-related prices may have on IPL’s and WPL’s customers’ demand for utility services;

 

   

the ability to defend against environmental claims brought by state and federal agencies, such as the United States of America (U.S.) Environmental Protection Agency (EPA), or third parties, such as the Sierra Club;

 

   

issues associated with environmental remediation efforts and with environmental compliance generally, including changing environmental laws and regulations and litigations associated with changing environmental laws and regulations;

 

   

the ability to recover through rates all environmental compliance and remediation costs, including costs for projects put on hold due to uncertainty of future environmental laws and regulations;

 

   

impacts of future tax benefits from deductions for repairs expenditures and mixed service costs and temporary differences from historical tax benefits from such deductions that are reversing into income tax expense in future periods;

 

   

the ability to find a purchaser for RMT, Inc. (RMT), to successfully negotiate a purchase agreement and to close the sale of RMT;

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;

 

   

issues related to electric transmission, including operating in Regional Transmission Organization (RTO) energy and ancillary services markets, the impacts of potential future billing adjustments and cost allocation changes from RTOs and recovery of costs incurred;

 

   

unplanned outages, transmission constraints or operational issues impacting fossil or renewable generating facilities and risks related to recovery of resulting incremental costs through rates;

 

   

Alliant Energy’s ability to successfully pursue appropriate appeals with respect to, and any liabilities arising out of, the alleged violation of the Employee Retirement Income Security Act of 1974 (ERISA) by Alliant Energy’s Cash Balance Pension Plan (Cash Balance Plan);

 

   

current or future litigation, regulatory investigations, proceedings or inquiries;

employee workforce factors, including changes in key executives, collective bargaining agreements and negotiations, work stoppages or additional restructurings;

access to technological developments;

 

   

any material post-closing adjustments related to any past asset divestitures;

 

   

material changes in retirement and benefit plan costs;

 

   

the impact of incentive compensation plans accruals;

 

   

the effect of accounting pronouncements issued periodically by standard-setting bodies;

 

   

the impact of adjustments made to deferred tax assets and liabilities from state apportionment assumptions;

 

   

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 ability to successfully complete tax audits and appeals with no material impact on earnings and cash flows;

 

   

the direct or indirect effects resulting from terrorist incidents, including cyber terrorism, or responses to such incidents; and

 

   

factors listed in Management’s Discussion and Analysis of Financial Condition and Results of Operations and in Item 1A Risk Factors in the combined Annual Report on Form 10-K filed by Alliant Energy, IPL and WPL for the year ended Dec. 31, 2011 (2011 Form 10-K).

IPL’s tax benefit rider—Alliant Energy’s and IPL’s “IPL’s tax benefit rider” regulatory liabilities in the above table decreased due to $20 million of regulatory liabilities used to credit IPL’s Iowa retail electric customers’ bills in the first quarter of 2012. Refer to Note 4 for additional details regarding IPL’s tax benefit rider.

(c) Utility Property, Plant and Equipment -

WPL’s Edgewater Unit 5 Emission Controls Project—WPL is currently installing a selective catalytic reduction (SCR) system at Edgewater Unit 5 to reduce nitrogen oxide (NOx) emissions at the generating facility. Construction began in the third quarter of 2010 and is expected to be completed by the end of 2012. The SCR is expected to help meet requirements under the Wisconsin Reasonably Available Control Technology (RACT) Rule, which require additional NOx emission reductions at Edgewater by May 2013. As of March 31, 2012, WPL recorded capitalized expenditures of $84 million and allowance for funds used during construction of $5 million for the SCR system in “Construction work in progress—Edgewater Generating Station Unit 5 emission controls” on Alliant Energy’s and WPL’s Condensed Consolidated Balance Sheets.

Wind Site in Green Lake and Fond du Lac Counties in Wisconsin—In 2009, WPL purchased development rights to an approximate 100 MW wind site in Green Lake and Fond du Lac Counties in Wisconsin. Due to events in the first quarter of 2011 resulting in uncertainty regarding wind siting requirements in Wisconsin and increased risks with permitting this wind site, WPL determined it would be difficult to sell or effectively use the site for wind development. As a result, WPL recognized a $5 million impairment in the first quarter of 2011 for the amount of capitalized costs incurred for this site. The impairment was recorded as a reduction in other utility property, plant and equipment, and a charge to “Utility—other operation and maintenance” in Alliant Energy’s and WPL’s Condensed Consolidated Statements of Income in the first quarter of 2011.

(d) Comprehensive Income (Loss)—For the three months ended March 31, 2012 and 2011, Alliant Energy had no other comprehensive income; therefore, its comprehensive income was equal to its net income for such periods. For the three months ended March 31, 2012 and 2011, IPL and WPL had no other comprehensive income; therefore their comprehensive income (loss) was equal to their earnings available (loss) for common stock for such periods.

(e) Cash Flows Presentation—Alliant Energy reports cash flows from continuing operations together with cash flows from discontinued operations in its Condensed Consolidated Statements of Cash Flows. Refer to Note 13 for details of cash flows from discontinued operations.

(2) UTILITY RATE CASES

WPL’s Retail Fuel-related Rate Case (2012 Test Year)—In December 2011, WPL received an order from the PSCW authorizing an annual retail electric rate increase of $4 million related to expected changes in retail electric production fuel and energy purchases costs (fuel-related costs). The December 2011 order also required WPL to defer direct Cross-State Air Pollution Rule (CSAPR) compliance costs that are not included in the fuel monitoring level and set a zero percent tolerance band for the CSAPR-related deferral. The 2012 fuel-related costs, excluding deferred CSAPR compliance costs, will be monitored using an annual bandwidth of plus or minus 2%. The rate change granted from this request was effective Jan. 1, 2012. Subsequent to the PSCW order issued in December 2011, the U.S. Court of Appeals for the D.C. Circuit stayed the implementation of CSAPR and as a result, the Clean Air Interstate Rule (CAIR) remains effective. Alliant Energy and WPL are currently unable to predict the final outcome of the CSAPR stay and its impact on their financial condition or results of operations.

(3) RECEIVABLES

Sales of Accounts Receivable—IPL maintains a Receivables Purchase and Sale Agreement (Agreement) whereby it may sell its customer accounts receivables, unbilled revenues and certain other accounts receivables to a third-party financial institution through wholly-owned and consolidated special purpose entities. In March 2012, IPL extended through March 2014 the purchase commitment from the third-party financial institution to which it sells its receivables. In exchange for the receivables sold, IPL receives cash proceeds from the third-party financial institution (based on seasonal limits up to $180 million), and deferred proceeds recorded in “Accounts receivable” on Alliant Energy’s and IPL’s Condensed Consolidated Balance Sheets.

(4) INCOME TAXES

Income Tax Rates—The provision for income taxes for earnings from continuing operations is based on an estimated annual effective tax rate that excludes the impact of significant unusual or infrequently occurring items, discontinued operations or extraordinary items. The effective tax rates for Alliant Energy, IPL and WPL differ from the federal statutory rate of 35% generally due to effects of utility rate making, including the tax benefit rider, tax credits, state income taxes and certain non-deductible expenses. Changes in state apportionment rates caused by the planned sale of Alliant Energy’s RMT business also impacted the effective tax rates in 2012 for Alliant Energy, IPL and WPL. The income tax rates shown in the following table for the three months ended March 31 were computed by dividing income taxes by income from continuing operations before income taxes.

 

     2012     2011  

Alliant Energy

     39.0     22.3

IPL

     125.4     5.9

WPL

     44.1     32.5

State Apportionment—Alliant Energy, IPL and WPL utilize state apportionment projections to record their deferred tax assets and liabilities each reporting period. Deferred tax assets and liabilities for temporary differences between the tax basis of assets and liabilities and the amounts reported in the consolidated financial statements are recorded utilizing currently enacted tax rates and estimates of future state apportionment rates expected to be in effect at the time the temporary differences reverse. These state apportionment projections are most significantly impacted by the estimated amount of revenues expected in the future from each state jurisdiction for Alliant Energy’s consolidated tax group, including both its regulated operations and its non-regulated operations. In the first quarter of 2012, Alliant Energy, IPL and WPL recorded $15.2 million, $8.1 million and $7.0 million, respectively, of deferred income tax expense due to changes in state apportionment projections caused by the planned sale of Alliant Energy’s RMT business. These income tax expense amounts

Table of Contents

recognized in the first quarter of 2012 increased Alliant Energy’s, IPL’s and WPL’s effective income tax rates for continuing operations for such period by 21.4%, 137.3% and 12.3%, respectively.

IPL’s Tax Benefit Rider—In January 2011, the Iowa Utilities Board (IUB) approved a tax benefit rider proposed by IPL, which utilizes tax-related regulatory liabilities to credit bills of Iowa retail electric customers beginning in February 2011 to help offset the impact of recent rate increases on such customers. These regulatory liabilities are related to tax benefits from tax accounting method changes for repairs, mixed service costs and allocation of insurance proceeds from the floods in 2008. Alliant Energy’s and IPL’s effective tax rates for the three months ended March 31, 2012 and 2011 include the impact of reducing income tax expense with offsetting reductions to regulatory liabilities as a result of implementing the tax benefit rider. In the first quarters of 2012 and 2011, $20 million and $7 million, respectively, of tax benefit rider-related regulatory liabilities were used to credit IPL’s Iowa retail electric customers’ bills. The tax impacts of the tax benefit rider are currently expected to decrease Alliant Energy’s and IPL’s 2012 annual income tax rates for continuing operations by 12.2% and 37.5%, respectively. In the first quarter of 2011, the tax impacts of the tax benefit rider decreased Alliant Energy’s and IPL’s income tax rates for continuing operations by 8.9% and 22.9%, respectively.

Production Tax Credits—Alliant Energy has three wind projects that are currently generating production tax credits: WPL’s 68 MW Cedar Ridge wind project, which began generating electricity in late 2008; IPL’s 200 MW Whispering Willow—East wind project, which began generating electricity in late 2009; and WPL’s 200 MW Bent Tree—Phase I wind project, which began generating electricity in late 2010. For the three months ended March 31, production tax credits (net of state tax impacts) resulting from these wind projects were as follows (in millions):

Deferred Tax Assets and Liabilities—In the first quarter of 2012, Alliant Energy’s, IPL’s and WPL’s non-current deferred tax liabilities recognized in “Deferred income taxes” on their Condensed Consolidated Balance Sheets increased $46 million, $18 million and $26 million, respectively. The increases in deferred tax liabilities were primarily related to property-related temporary differences recorded in the first quarter of 2012 from bonus depreciation deductions available in 2012. These items were partially offset by increases in deferred tax assets recorded in the first quarter of 2012 as a result of increasing federal and state net operating loss carryforwards primarily due to such bonus depreciation deductions.

Bonus Depreciation Deductions—In 2010, the Small Business Jobs Act of 2010 (SBJA) and the Tax Relief, Unemployment Insurance Reauthorization and Job Creation Act of 2010 (the Act) were enacted. The most significant provisions of the SBJA and the Act for Alliant Energy, IPL and WPL are related to the extension of bonus depreciation deductions for certain expenditures for property that are placed in service through Dec. 31, 2012. Based on capital projects expected to be placed into service in 2012, Alliant Energy currently estimates its total bonus depreciation deductions to be claimed in its 2012 federal income tax return will be approximately $418 million ($114 million for IPL and $203 million for WPL).

Carryforwards—At March 31, 2012, tax carryforwards and associated deferred tax assets and expiration dates were estimated as follows (in millions):

Uncertain Tax Positions—It is reasonably possible that Alliant Energy, IPL and WPL could have material changes to their unrecognized tax benefits during the 12 months ending March 31, 2013 as a result of the expected issuance in 2012 of revenue procedures clarifying the treatment of repair expenditures for electric generation and gas distribution property. An estimate of the expected changes during the 12 months ending March 31, 2013 cannot be determined at this time.

(b) Equity Incentive Plans—A summary of compensation expense and the related income tax benefits recognized for share-based compensation awards for the three months ended March 31 was as follows (in millions):

Income tax benefits

     0.6         0.9         0.3         0.5         0.3         0.4   

As of March 31, 2012, total unrecognized compensation cost related to share-based compensation awards was $14.1 million, which is expected to be recognized over a weighted average period of between one and two years. Share-based compensation expense is recognized on a straight-line basis over the requisite service periods and is primarily recorded in “Utility—other operation and maintenance” in the Condensed Consolidated Statements of Income.

In the first quarter of 2012, Alliant Energy granted performance shares, performance units, performance-contingent restricted stock and performance contingent cash awards to certain key employees. Payouts of nonvested awards issued in 2012 are prorated at retirement, death, disability or involuntary termination without cause based on time worked during the first year of the performance period and achievement of the performance criteria. Upon achievement of the performance criteria, payouts of these awards to participants who terminate employment after the first year of the performance period due to retirement, death, disability or involuntary termination without cause are not prorated. Participants’ nonvested awards issued in 2012 are forfeited if the participant voluntarily leaves Alliant Energy or is terminated for cause.

Performance Shares and UnitsAlliant Energy assumes it will make future payouts of its performance shares and units in cash; therefore, performance shares and units are accounted for as liability awards.

Performance Shares—A summary of the performance shares activity for the three months ended March 31 was as follows:

 

     2012     2011  
     Shares (a)     Shares (a)

Nonvested shares, March 31

     170,611        240,897   
  

 

 

   

 

 

 

 

(a) Share amounts represent the target number of performance shares. Each performance share’s value is based on the price of one share of Alliant Energy’s common stock at the end of the performance period. The actual number of shares that will be paid out upon vesting is dependent upon actual performance and may range from zero to 200% of the target number of shares.
(b) In the first quarter of 2012, 111,980 performance shares granted in 2009 vested at 162.5% of the target, resulting in payouts valued at $8.0 million, which consisted of a combination of cash and common stock (6,399 shares). In the first quarter of 2011, 57,838 performance shares granted in 2008 vested at 75% of the target, resulting in payouts valued at $1.6 million, which consisted of a combination of cash and common stock (1,387 shares).

At March 31, 2012, fair values of nonvested performance shares and units were calculated using a Monte Carlo simulation to determine the anticipated total shareowner returns of Alliant Energy and its investor-owned utility peer groups. Expected volatility was based on historical volatilities using daily stock prices over the past three years. Expected dividend yields were calculated based on the most recent quarterly dividend rates announced prior to the measurement date and stock prices at the measurement date. The risk-free interest rate was based on the three-year U.S. Treasury rate in effect as of the measurement date.

Restricted StockRestricted stock consists of time-based and performance-contingent restricted stock.

Valuation Techniques -

Money market fund investments—As of March 31, 2012, money market fund investments were measured at fair value using quoted market prices on listed exchanges.

Derivative assets and derivative liabilities—Alliant Energy, IPL and WPL periodically use derivative instruments for risk management purposes to mitigate exposures to fluctuations in certain commodity prices, transmission congestion costs and currency exchange rates. Alliant Energy, IPL and WPL maintain risk policies that govern the use of derivative instruments. Alliant Energy’s, IPL’s and WPL’s derivative instruments as of March 31, 2012 and Dec. 31, 2011 were not designated as hedging instruments. Alliant Energy’s, IPL’s and WPL’s derivative instruments as of March 31, 2012 and Dec. 31, 2011 included electric physical forward purchase contracts and swap contracts to mitigate pricing volatility for the electricity purchased to supply to IPL’s and WPL’s customers; electric physical forward sale contracts to offset long positions created by reductions in electricity demand forecasts; natural gas swap contracts to mitigate pricing volatility for the fuel used to supply to the natural gas-fired electric generating facilities they operate; natural gas options to mitigate price increases during periods of high demand or lack of supply; financial transmission rights (FTRs) acquired to manage transmission congestion costs; natural gas physical forward purchase and natural gas option contracts to mitigate pricing volatility for natural gas supplied to IPL’s and WPL’s retail customers; and natural gas physical purchase and sale contracts to optimize the value of natural gas pipeline capacity.

IPL’s and WPL’s swap, option and physical forward commodity contracts were non-exchange-based derivative instruments and were valued using indicative price quotations available through a pricing vendor that provides daily exchange forward price settlements, from broker or dealer quotations or from on-line exchanges. The indicative price quotations reflected the average of the bid-ask mid-point prices and were obtained from sources believed to provide the most liquid market for the commodity. IPL and WPL corroborated a portion of these indicative price quotations using quoted prices for similar assets or liabilities in active markets and categorized derivative instruments based on such indicative price quotations as Level 2. IPL’s and WPL’s commodity contracts that were valued using indicative price quotations based on significant assumptions such as seasonal or monthly shaping and indicative price quotations that could not be readily corroborated were categorized as Level 3. IPL’s and WPL’s swap, option and physical forward commodity contracts were predominately at liquid trading points. IPL’s and WPL’s FTRs were measured at fair value each reporting date using monthly or annual auction shadow prices from relevant auctions. Refer to Note 10 for additional details of derivative assets and derivative liabilities.

Deferred proceeds (sales of receivables)—The fair value of IPL’s deferred proceeds related to its sales of receivables program was calculated each reporting date using the cost approach valuation technique. The fair value represents the carrying amount of receivables sold less the allowance for doubtful accounts associated with the receivables sold and cash proceeds received from the receivables sold. Deferred proceeds represent IPL’s maximum exposure to loss related to the receivables sold due to the short-term nature of the collection period. Refer to Note 3 for additional information regarding deferred proceeds.

Long-term debt (including current maturities)—For long-term debt instruments that are actively traded, the fair value was based upon quoted market prices for similar liabilities each reporting date. For long-term debt instruments that are not actively traded, the fair value was based on discounted cash flow methodology and utilizes assumptions of current market pricing curves at each reporting date. Refer to Note 7(b) for additional information regarding long-term debt.

Cumulative preferred stock of subsidiaries—The fair value of IPL’s 8.375% cumulative preferred stock was based on its closing market price quoted by the New York Stock Exchange on each reporting date. The fair value of WPL’s 4.50% cumulative preferred stock was based on the closing market price quoted by the NYSE Amex LLC on each reporting date. The fair value of WPL’s remaining preferred stock was calculated based on the market yield of similar securities.

Valuation HierarchyFair value measurement accounting establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The three levels of the fair value hierarchy and examples of each are as follows:

Level 1—Pricing inputs are quoted prices available in active markets for identical assets or liabilities as of the reporting date. As of March 31, 2012, Level 1 items included money market fund investments, IPL’s 8.375% cumulative preferred stock and WPL’s 4.50% cumulative preferred stock.

Level 2—Pricing inputs are quoted prices for similar assets or liabilities in active markets or quoted prices for identical or similar assets or liabilities in markets that are not active as of the reporting date. As of March 31, 2012 and Dec. 31, 2011, Level 2 items included IPL’s and WPL’s non-exchange traded commodity contracts. Level 2 items as of March 31, 2012 also included the remainder of WPL’s cumulative preferred stock and substantially all of the long-term debt instruments.

Level 3—Pricing inputs are unobservable inputs for assets or liabilities for which little or no market data exist and require significant management judgment or estimation. As of March 31, 2012 and Dec. 31, 2011, Level 3 items included IPL’s deferred proceeds, and IPL’s and WPL’s FTRs and certain commodity contracts.

The fair value hierarchy gives the highest priority to quoted prices in active markets (Level 1) and the lowest priority to unobservable data (Level 3). In some cases, the inputs used to measure fair value might fall in different levels of the fair value hierarchy. The lowest level input that is significant to a fair value measurement in its entirety determines the applicable level in the fair value hierarchy. Assessing the significance of a particular input to the fair value measurement in its entirety requires judgment, considering factors specific to the asset or liability. Items subject to fair value measurement disclosure requirements were as follows (Not Applicable (N/A); in millions):

In accordance with IPL’s and WPL’s fuel and natural gas recovery mechanisms, prudently incurred costs from derivative instruments are recovered from customers in the future after any losses are realized. Based on these recovery mechanisms, the changes in the fair value of derivative liabilities resulted in comparable changes to regulatory assets and the changes in the fair value of derivative assets resulted in comparable changes to regulatory liabilities on the Condensed Consolidated Balance Sheets.

The significant unobservable inputs (Level 3 inputs) used in the fair value measurement of IPL’s and WPL’s commodity contracts are forecasted electricity and natural gas prices, and the expected volatility of such prices. Significant changes in any of those inputs would result in a significantly lower or higher fair value measurement. Information for fair value measurements using significant unobservable inputs (Level 3 inputs) for the three months ended March 31 was as follows (in millions):

Electric and Natural Gas Commodity ContractsAs of March 31, 2012, the fair values of Alliant Energy’s, IPL’s and WPL’s electric and natural gas commodity contracts classified as Level 3, excluding FTRs, were recognized as net derivative liabilities of $18.4 million, $14.3 million and $4.1 million, respectively. These commodity contracts were valued using a market approach technique that utilizes significant observable inputs to estimate forward commodity prices. Forward electric prices are estimated using market information obtained from counterparties and brokers, including bids, offers, historical transactions (including historical price differences between locations with both observable and unobservable prices) and executed trades. Forward natural gas prices are estimated using the most recent quoted observable inputs applied to future months (including historical price differences between locations with both observable and unobservable prices). Observable inputs are obtained from compiled third-party pricing data sources and include bids, offers, historical transactions and executed trades. Forward electric price commodity curves that extend beyond currently available observable inputs utilize market prices for the most recent period for which observable inputs are available. Observable inputs include bids, offers, historical transactions and executed trades.

Alliant Energy, IPL and WPL generally record gains and losses from IPL’s and WPL’s derivative instruments with offsets to regulatory assets or regulatory liabilities, based on their fuel and natural gas cost recovery mechanisms, as well as other specific regulatory authorizations. For the three months ended March 31, 2012 and 2011, gains and losses from commodity derivative instruments not designated as hedging instruments were recorded as follows (in millions):

Regulatory liabilities

     1.4        1.5        —          0.8        1.4        0.7   

Losses from commodity contracts during the three months ended March 31, 2012 were primarily due to impacts of decreases in electricity and natural gas prices during such period.

Credit Risk-related Contingent Features—Alliant Energy, IPL and WPL have entered into various agreements that contain credit risk-related contingent features including requirements for them to maintain certain credit ratings from each of the major credit rating agencies and limitations on their liability positions under the various agreements based upon their credit ratings. In the event of a downgrade in their credit ratings or if their liability positions exceed certain contractual limits, Alliant Energy, IPL or WPL may need to provide credit support in the form of letters of credit or cash collateral up to the amount of their exposure under the contracts, or may need to unwind the contracts and pay the underlying liability positions.

Certain of these agreements with credit risk-related contingency features are accounted for as derivative instruments. The aggregate fair value of all derivatives with credit risk-related contingent features that were in a net liability position on March 31, 2012 was $83.2 million, $38.1 million and $45.1 million for Alliant Energy, IPL and WPL, respectively. At March 31, 2012, Alliant Energy, IPL and WPL all had investment-grade credit ratings. However, IPL exceeded its liability position with one counterparty requiring it to post $1.0 million of cash collateral. If the most restrictive credit risk-related contingent features for derivative agreements in a net liability position were triggered on March 31, 2012, Alliant Energy, IPL and WPL would be required to post an additional $82.2 million, $37.1 million and $45.1 million, respectively, of credit support to their counterparties.

(11) COMMITMENTS AND CONTINGENCIES

(a) Operating Expense Purchase Obligations—Alliant Energy, IPL and WPL have entered into various commodity supply, transportation and storage contracts to meet their obligations to deliver electricity and natural gas to IPL’s and WPL’s utility customers. Alliant Energy, IPL and WPL also enter into other operating expense purchase obligations with various vendors for other goods and services. At March 31, 2012, minimum future commitments related to these operating expense purchase obligations were as follows (in millions):

(b) Legal Proceedings—

Air Permitting Violation ClaimsIn September 2010, Sierra Club filed in the U.S. District Court for the Western District of Wisconsin a complaint against WPL, as owner and operator of the Nelson Dewey Generating Station (Nelson Dewey) and the Columbia Energy Center (Columbia), based on allegations that modifications were made at the facilities without complying with the Prevention of Significant Deterioration (PSD) program requirements, Title V Operating Permit requirements of the Clean Air Act (CAA) and state regulatory counterparts contained within the Wisconsin state implementation plan (SIP) designed to implement the CAA. In October 2010, WPL responded to these claims related to Nelson Dewey and Columbia by filing with the U.S. District Court an answer denying the Columbia allegations and a motion to dismiss the Nelson Dewey allegations based on statute of limitations arguments. In November 2010, WPL filed a motion to dismiss the Nelson Dewey and Columbia allegations based on lack of jurisdiction. Sierra Club has responded to the motions. In January 2012, the Court reset the trial date to Dec. 10, 2012 and scheduled a status conference for Feb. 15, 2012 to receive an update on settlement progress. At the Feb. 15, 2012 status conference, the Court reaffirmed the Dec. 10, 2012 trial date and set a pre-trial schedule that allows the parties to work toward settlement.

In September 2010, Sierra Club filed in the U.S. District Court for the Eastern District of Wisconsin a complaint against WPL, as owner and operator of the Edgewater Generating Station (Edgewater), which contained similar allegations regarding air permitting violations at Edgewater. In the Edgewater complaint, additional allegations were made regarding violations of emission limits for visible emissions. In February 2011, WPL responded to these claims related to Edgewater by filing with the U.S. District Court an answer denying the allegations and a motion to dismiss the allegations based on lack of jurisdiction. In December 2011, the Court stayed all discovery and scheduling deadlines for 60 days (through Feb. 15, 2012) so that the Parties may continue settlement negotiations. In February 2012, the Court extended the stay. In April 2012, WPL and Sierra Club filed a joint settlement status report requesting the Court to stay all case management deadlines and agreeing to file a settlement status report by July 15, 2012, if no consent decree is filed by that date. WPL and Sierra Club are currently engaged in settlement discussions regarding the Nelson Dewey, Columbia and Edgewater air permitting violation claims.

In 2009, the EPA sent a Notice of Violation (NOV) to WPL as an owner and the operator of Edgewater, Nelson Dewey and Columbia. The NOV alleges that the owners failed to comply with appropriate pre-construction review and permitting requirements and as a result violated the PSD program requirements, Title V Operating Permit requirements of the CAA and the Wisconsin SIP. WPL is engaged in settlement negotiations with the EPA in conjunction with the settlement negotiations with the Sierra Club discussed above.

In response to similar EPA CAA enforcement initiatives, certain utilities have elected to settle with the EPA, while others have elected to litigate. If the EPA and/or Sierra Club successfully prove their claims that projects completed in the past at Edgewater, Nelson Dewey and Columbia required either a state or federal CAA permit, WPL may, under the applicable statutes, be required to pay civil penalties in amounts of up to $37,500 per day for each violation and/or complete actions for injunctive relief. Payment of fines and/or injunctive relief could be included in a settlement outcome. Injunctive relief contained in settlements or court-ordered remedies for other utilities required the installation of emission control technology, changed operating conditions including use of alternative fuels other than coal, caps for emissions and limitations on generation including retirement of generating units, and other beneficial environmental projects. If similar remedies are required for final resolution of these matters at Edgewater, Nelson Dewey and Columbia, Alliant Energy and WPL would incur additional capital and operating expenditures. Alliant Energy and WPL are continuing to analyze the allegations and are unable to predict the impact of the allegations on their financial condition or results of operations, but believe that the outcome could be significant. WPL and the other owners of Edgewater and Columbia are exploring settlement options while simultaneously defending against these allegations. Alliant Energy and WPL believe the projects at Edgewater, Nelson Dewey and Columbia were routine or not projected to increase emissions and therefore did not violate the permitting requirements of the CAA.

Alliant Energy and WPL do not currently believe any material losses from these air permitting violation claims are both probable and reasonably estimated and therefore have not recognized any material related loss contingency amounts as of March 31, 2012. Alliant Energy and WPL are not able to estimate the possible loss or range of possible loss related to these air permit violation claims given the various litigation and settlement scenarios being pursued to resolve this contingency as well as uncertainty regarding which, if any, allegations will be determined to be violations and the nature and cost of any fines and injunctive relief that could be required to resolve any violations.

Alliant Energy Cash Balance Pension Plan (Plan)In February 2008, a class action lawsuit was filed against the Plan in the U.S. District Court for the Western District of Wisconsin (Court). The complaint alleged that certain Plan participants who received distributions prior to their normal retirement age did not receive the full benefit to which they were entitled in violation of ERISA because the Plan applied an improper interest crediting rate to project the cash balance account to their normal retirement age. These Plan participants were limited to individuals who, prior to normal retirement age, received a lump sum distribution or an annuity payment. The Court certified two subclasses of plaintiffs that in aggregate include all persons vested or partially vested in the Plan who received these distributions from Jan. 1, 1998 to Aug. 17, 2006 including: (1) persons who received distributions from Jan. 1, 1998 through Feb. 28, 2002; and (2) persons who received distributions from March 1, 2002 to Aug. 17, 2006.

In June 2010, the Court issued an opinion and order that granted the plaintiffs’ motion for summary judgment on liability in the lawsuit and decided with respect to damages that prejudgment interest on damages would be allowed. In December 2010, the Court issued an opinion and order that decided the interest crediting rate that the Plan used to project the cash balance accounts of the plaintiffs during the class period should have been 8.2% and that a pre-retirement mortality discount would not be applied to the damages calculation. In March 2011, the Court issued an opinion and order that prejudgment interest on damages would be calculated using the average prime rate from the date that the Plan failed to make the total payment to a particular participant through the date of the final judgment (which has not yet been issued). In September 2011, plaintiffs filed a motion for leave to file a supplemental complaint to assert that the 2011 amendment to the Plan, made to conform with the IRS determination letter (described below), was itself an ERISA violation. In November 2011, the Court allowed the filing of the plaintiffs’ supplemental complaint and denied a separate motion for reconsideration filed by the Plan arguing that certain of plaintiffs’ claims were time-barred. Following the November 2011 ruling, plaintiffs filed a supplemental complaint and the Plan filed an answer and an amended answer. In March 2012, the Plan and the plaintiffs each filed motions for summary judgment related to the supplemental complaint, and the plaintiffs filed a motion for class certification, seeking to amend the class definition and for reappointment of class representatives and class counsel. In April 2012, both the Plan and the plaintiffs filed briefs opposing the other party’s motion for summary judgment. The Plan also filed a brief opposing the plaintiffs’ motion for class certification.

Based on opinions and orders issued by the Court to date and the $10.2 million of IRS-related offset benefits paid by the Plan in 2011, the Plan currently estimates that the trial court judgment of damages, after offsetting the additional benefits paid to participants by the Plan, will be at least $17 million, which includes prejudgment interest through March 31, 2012, but does not include any award for plaintiffs’ attorney’s fees or costs. The trial court judgment of damages related to the additional claims newly asserted in the supplemental complaint by the plaintiffs in November 2011 is uncertain. Following resolution of the supplemental complaint, the Plan may appeal the trial court judgment of damages to the Seventh Circuit Court of Appeals. As a result, Alliant Energy, IPL and WPL do not currently believe any material losses related to the final judgment of damages from this class action lawsuit are both probable and reasonably estimated, and therefore have not recognized any material loss contingency amounts for the final judgment of damages as of March 31, 2012. Alliant Energy, IPL and WPL are currently unable to predict the final outcome of the class action lawsuit or the ultimate impact on their financial condition or results of operations but believe the outcome could have a material effect on their retirement plan funding and expense.

The IRS also considered the interest crediting rate used to project the cash balance account to participants’ normal retirement age as part of its review of Alliant Energy’s request for a favorable determination letter with respect to the tax-qualified status of the Plan. Alliant Energy reached an agreement with the IRS, which resulted in a favorable determination letter for the Plan in 2011. The agreement with the IRS required Alliant Energy to amend the Plan in 2011 resulting in $10.2 million of aggregate additional benefits paid by Alliant Energy to certain former participants in the Plan in 2011. The $10.2 million of aggregate payments by Alliant Energy are an offset against any final judgment of damages by the Court in the case discussed above, in whole or in part, depending on the scope of the final judgment.

RMT Contract Disputes—In September 2011, RMT filed a lawsuit in the U.S. District Court for the Western District of Wisconsin alleging, among other things, breach of contract against Cable System Installation (CSI), a subcontractor to RMT on several solar projects in New Jersey. The complaint alleges that CSI breached its contract with RMT by failing to complete the work, by failing to complete the work in a timely manner, by failing to perform work according to the contract, for abandonment of work, and for other related claims. RMT incurred additional costs to replace CSI and to complete CSI’s work with alternative subcontractors, incurred liquidated damages assessed by the project owners due to project delays, and had liens filed by CSI’s vendors that CSI has not paid. The lawsuit seeks to recover all costs incurred by RMT as a result of the breaches of contract by CSI. CSI filed an answer and counterclaims against RMT asserting that RMT owes CSI additional amounts for work performed under the contract that have not been paid to date. CSI also filed a motion requesting the case be transferred to New Jersey. CSI has filed liens against the projects based on claims that they have not been paid for work performed under the contract with RMT and vendors of CSI have filed liens against the projects based on claims

that they have not been paid as required under their agreements with CSI. Two vendors of CSI have also filed lawsuits in New Jersey including claims against both CSI and RMT resulting from work allegedly performed by the two vendors but not paid by CSI or RMT. As of March 31, 2012, RMT has posted bonds of $17 million to discharge the liens filed against the New Jersey project sites by CSI and CSI’s vendors. Alliant Energy does not currently believe any material losses from these claims are both probable and reasonably estimated and therefore has not recognized any material related loss contingency amounts as of March 31, 2012. Alliant Energy is currently not able to estimate the possible loss or range of possible loss related to these claims given the early state of the lawsuits. Alliant Energy also has not recognized any material benefits from the lawsuit filed by RMT against CSI as of March 31, 2012.

(c) Guarantees and Indemnifications—Alliant Energy provided an indemnification associated with the 2007 sale of its Mexico business for losses resulting from potential breach of the representations and warranties made by Alliant Energy on the sale date and for the breach of its obligations under the sale agreement. The indemnification has a maximum limit of $20 million and expires in June 2012. Alliant Energy believes the likelihood of having to make any material cash payments under this indemnification is remote. Alliant Energy has not recognized any material liabilities related to this indemnification as of March 31, 2012.

Alliant Energy also continues to guarantee the abandonment obligations of Whiting Petroleum Corporation (Whiting) under the Point Arguello partnership agreements following the sale of Alliant Energy’s remaining interest in Whiting in 2004. The guarantee does not include a maximum limit. As of March 31, 2012, the present value of the abandonment obligations is estimated at $29 million. Alliant Energy believes that no payments will be made under this guarantee. Alliant Energy has not recognized any material liabilities related to this guarantee as of March 31, 2012.

RMT provides renewable energy services to clients throughout the U.S., including facility siting, permitting, design, procurement, construction and high voltage connection services for wind and solar projects. Alliant Energy has guaranteed RMT’s performance obligations related to certain of these projects. As of March 31, 2012, Alliant Energy had $609 million of performance guarantees outstanding with $101 million, $325 million and $183 million expiring in 2012, 2013 and 2014, respectively. RMT has also provided surety bonds in support of the payment and performance obligations of certain of these projects and Alliant Energy has guaranteed RMT’s indemnity obligations to the surety company. As of March 31, 2012, Alliant Energy had $114 million in surety bonds and related Alliant Energy performance guarantees outstanding with $112 million expiring in 2012 and $2 million expiring in 2013. Alliant Energy currently believes that no material cash payments will be made under any of these obligations. Alliant Energy has not recognized any material liabilities related to these obligations as of March 31, 2012.

 

(d) Environmental Matters—

Manufactured Gas Plant (MGP) SitesIPL and WPL have current or previous ownership interests in 40 and 14 sites, respectively, previously associated with the production of gas for which they may be liable for investigation, remediation and monitoring costs. IPL and WPL have received letters from state environmental agencies requiring no further action at 11 and 9 of these sites, respectively. Additionally, IPL has met state environmental agency expectations at 3 additional sites requiring no further action for soil remediation. 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 the sites in order to protect public health and the environment.

Alliant Energy, IPL and WPL record environmental liabilities related to these MGP sites based upon periodic studies. Such amounts are based on the best current estimate of the remaining amount to be incurred for investigation, remediation and monitoring costs for those sites where the investigation process has been or is substantially completed, and the minimum of the estimated cost range for those sites where the investigation is in its earlier stages. There are inherent uncertainties associated with the estimated remaining costs for MGP projects primarily due to unknown site conditions and potential changes in regulatory agency requirements. It is possible that future cost estimates will be greater than current estimates as the investigation process proceeds and as additional facts become known. The amounts recognized as liabilities are reduced for expenditures incurred and are adjusted as further information develops or circumstances change. Costs of future expenditures for environmental remediation obligations are not discounted. Management currently estimates the range of remaining costs to be incurred for the investigation, remediation and monitoring of these sites to be $21 million ($18 million for IPL and $3 million for WPL) to $45 million ($41 million for IPL and $4 million for WPL). At March 31, 2012, Alliant Energy, IPL and WPL recorded $31 million, $28 million and $3 million, respectively, in current and non-current environmental liabilities for their remaining costs to be incurred for these MGP sites.

Other Environmental ContingenciesIn addition to the environmental liabilities discussed above, Alliant Energy, IPL and WPL are also monitoring various environmental regulations that may have a significant impact on their future operations. Given uncertainties regarding the outcome, timing and compliance plans for these environmental matters, Alliant Energy, IPL and WPL are currently not able to determine the complete financial impact of these regulations but do believe that future capital investments and/or modifications to their electric generating facilities to comply with these regulations could be significant. Specific current, proposed or potential environmental matters that may require significant future expenditures by Alliant Energy, IPL and WPL include, among others: CAIR, CSAPR, Clean Air Visibility Rule, Utility Maximum Achievable Control Technology (MACT) Rule, Wisconsin State Mercury Rule, Wisconsin RACT Rule, Ozone National Ambient Air Quality Standards (NAAQS) Rule, Fine Particle NAAQS Rule, Nitrogen Dioxide NAAQS Rule, SO2 NAAQS Rule, Industrial Boiler and Process Heater MACT Rule, Federal Clean Water Act including Section 316(b), Wisconsin and Iowa State Thermal Rules, Hydroelectric Fish Passage Device, Coal Combustion Residuals, Polychlorinated Biphenyls, and various legislation and EPA regulations to monitor and regulate the emission of greenhouse gases (GHG) including the EPA New Source Performance Standard (NSPS) for GHG Emissions from Electric Utilities and the EPA GHG Tailoring Rule. Some recent developments concerning these environmental matters are included below:

Water Quality—

Hydroelectric Fish Passages Device—In March 2012, the Federal Energy Regulatory Commission (FERC) extended the deadline to install an agency-approved fish passage device at WPL’s Prairie du Sac hydro plant to July 1, 2015.

GHG Emissions—

EPA NSPS for GHG Emissions from Electric Utilities—In April 2012, the EPA published proposed NSPS for GHG, including carbon dioxide (CO2) emissions from new fossil-fueled electric generating units (EGUs) larger than 25 MW with an output-based emissions rate limitation of 1,000 pounds of CO2 per MWh. This emissions rate limitation is expected to be effective upon the EPA’s issuance of the final rule in the second quarter of 2013.

(13) DISCONTINUED OPERATIONS AND ASSETS AND LIABILIITES HELD FOR SALE

Alliant Energy is currently pursuing the disposal of its RMT business in order to narrow its strategic focus and risk profile. RMT was included in Alliant Energy’s “Non-regulated—RMT” segment. Alliant Energy currently expects to complete the disposal of RMT in 2012. The RMT business qualified as assets and liabilities held for sale as of March 31, 2012. In March 2011, Alliant Energy sold its Industrial Energy Applications, Inc. (IEA) business to narrow its strategic focus and risk profile and received net proceeds of $5 million. IEA was included in Alliant Energy’s “Other Non-regulated, Parent and Other” segment.

The operating results of RMT and IEA have been separately classified and reported as discontinued operations in Alliant Energy’s Condensed Consolidated Statements of Income.

(15) VARIABLE INTEREST ENTITIES (VIEs)

After making an ongoing exhaustive effort, Alliant Energy and WPL concluded they were unable to obtain the information necessary from the counterparty (a subsidiary of Calpine Corporation) for the Riverside PPA for Alliant Energy and WPL to determine whether the counterparty is a VIE and if WPL is the primary beneficiary. This PPA is currently accounted for as an operating lease. The counterparty for the Riverside PPA sells a portion of its generating capacity to WPL and can sell its energy output to WPL. Alliant Energy’s and WPL’s maximum exposure to loss from this PPA is undeterminable due to the inability to obtain the necessary information to complete such evaluation. Alliant Energy’s (primarily WPL’s) costs, excluding fuel costs, related to the Riverside PPA were $6.3 million and $6.4 million for the three months ended March 31, 2012 and 2011, respectively.

In April 2012, the PSCW approved WPL’s Certificate of Authority (CA) application to acquire Riverside for approximately $393 million by the end of 2012. WPL’s purchase of Riverside would replace the 490 MW of electricity output currently obtained from the Riverside PPA to meet the demand of its customers. WPL currently plans to complete the acquisition in December 2012.

The table above includes utility, and non-regulated and parent earnings per share from continuing operations, which are non-GAAP financial measures. Alliant Energy believes utility, and non-regulated and parent earnings per share from continuing operations 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 management also uses utility earnings per share from continuing operations to determine incentive compensation.

Utility—Lower income from continuing operations in the first quarter of 2012 compared to the same period in 2011 was primarily due to:

 

   

an estimated $0.16 per share decrease in revenues from lower sales in the first quarter of 2012 compared to the first quarter of 2011 due to weather conditions;

 

   

$0.14 per share related to the impact of state income tax charges in the first quarter of 2012 due to changes in state apportionment projections caused by Alliant Energy’s planned sale of the RMT business; and

 

   

$0.11 per share related to the impact of IPL’s tax benefit rider in the first quarter of 2012 compared to the first quarter of 2011, which is not expected to impact the full year results.

These items were partially offset by:

 

   

$0.03 per share impact from an impairment of WPL’s wind site in Wisconsin in the first quarter of 2011.

Non-regulated and parent—Higher income from continuing operations in the first quarter of 2012 compared to the same period in 2011 was primarily due to $0.04 per share of higher income tax benefits at the parent company due to the impact of IPL’s tax benefit rider.

Refer to “Alliant Energy’s Results of Operations,” “IPL’s Results of Operations” and “WPL’s Results of Operations” for additional details regarding the various factors impacting their respective earnings during the first quarters of 2012 and 2011.

Strategic Overview

Alliant Energy’s, IPL’s and WPL’s strategic plans focus on their core business of delivering regulated electric and natural gas service in Iowa, Wisconsin, and Minnesota. The strategic plans are built upon three key elements: competitive costs, safe and reliable service and balanced generation. The strategic plans for Alliant Energy, IPL and WPL include purchasing and/or constructing natural gas-fired electric generating facilities, implementing emission controls and performance upgrades at their more-efficient coal-fired electric generating facilities, constructing a new wind generating facility, and fuel switching at, and retirement of, certain older and less-efficient coal-fired generating facilities. Key strategic plan developments impacting Alliant Energy, IPL and WPL during 2012 include:

 

   

March 2012—The Midwest Independent Transmission System Operator (MISO) indicated that the retirement of WPL’s Nelson Dewey Units 1 and 2 may result in reliability issues and that transmission upgrades are necessary to enable the retirement. Under the current MISO tariff, the specific timing for the retirement of Nelson Dewey Units 1 and 2 could depend on the timing of the required transmission upgrades and various operational, market and other factors.

 

   

April 2012—The PSCW approved WPL’s CA application to acquire Riverside for approximately $393 million by the end of 2012. Subject to receiving all remaining regulatory approvals, WPL currently plans to complete the acquisition in December 2012.

 

   

April 2012—IPL and MidAmerican each filed an updated Emissions Plan and Budget (EPB) with the IUB. IPL’s EPB includes emission control projects for Ottumwa Unit 1 and Lansing Unit 4. MidAmerican’s EPB includes emission control projects for George Neal Units 3 and 4. Alliant Energy and IPL currently expect the IUB to issue their decisions on IPL’s and MidAmerican’s EPBs by the end of 2012.

Refer to “Strategic Overview” for additional details regarding strategic plan developments.

Rate Matters

Alliant Energy’s utility subsidiaries, IPL and WPL, are subject to federal regulation by FERC, which has jurisdiction over wholesale electric rates, and state regulation in Iowa, Wisconsin and Minnesota for retail utility rates. Key regulatory developments impacting Alliant Energy, IPL and WPL during 2012 include:

 

   

May 2012—After discussion with PSCW staff and major intervener groups, WPL filed a retail base rate filing based on a forward-looking test period that includes 2013 and 2014. The filing requests approval for WPL to implement a decrease in annual retail natural gas base rates of $13 million effective Jan. 1, 2013 followed by a freeze of such natural gas base rates through the end of 2014. The filing also requests authority to maintain customer base rates for WPL’s retail electric customers at their current levels through the end of 2014. Recovery of the costs for the planned acquisition of Riverside and emission control projects at Edgewater Unit 5 and Columbia Units 1 and 2 are included in the request. The recovery of the costs for these capital projects are offset by decreases in rate base resulting from increased net deferred tax liabilities, the impact of amortizations of regulatory assets and regulatory liabilities, and the reduction of capacity payments. WPL’s May 2012 retail base rate filing included a return on common equity of 10.4% and the following related provisions: (1) WPL may request a change in retail base rates if its annual return on common equity falls below 8.5%; and (2) WPL must defer a portion of its earnings if its annual return on common equity exceeds 10.65%. The amount of earnings WPL must defer is equal to 50% of its excess earnings between 10.66% and 11.40% and 100% of any excess earnings above 11.40%.

Refer to “Rate Matters” for additional details regarding regulatory developments.

Environmental Matters

Alliant Energy, IPL and WPL are subject to regulation of environmental matters by various federal, state and local authorities. Key environmental developments during 2012 that may impact Alliant Energy, IPL and WPL include:

 

   

March 2012—FERC extended the deadline to install an agency-approved fish passage device at WPL’s Prairie du Sac hydro plant to July 1, 2015.

 

   

April 2012—The EPA published proposed NSPS for GHG, including CO2 emissions from new fossil-fueled EGUs larger than 25 MW with an output-based standard of 1,000 pounds of CO2 per MWh. This emissions rate limitation is expected to be effective upon the EPA’s issuance of the final rule in the second quarter of 2013.

Refer to “Environmental Matters” for additional details regarding environmental developments.

Liquidity and Capital Resources

Based on their current liquidity positions and capital structures, Alliant Energy, IPL and WPL believe they will be able to secure the additional capital required to implement their strategic plans and to meet their long-term contractual obligations. Key financing developments impacting Alliant Energy, IPL and WPL during 2012 include:

 

   

March 2012—FERC authorized Corporate Services to issue up to $150 million in long-term debt securities and to maintain up to $200 million in short-term debt securities outstanding (including borrowings from its parent or other affiliates) during the period from March 31, 2012 through March 30, 2014.

 

   

March 2012—IPL extended through March 2014 the purchase commitment from the third-party financial institution to which it sells its receivables.

 

   

March 2012—At March 31, 2012, Alliant Energy and its subsidiaries had $918 million of available capacity under their revolving credit facilities, $35 million of available capacity at IPL under its sales of accounts receivable program and $31 million of cash and cash equivalents.

 

   

April 2012—Alliant Energy exercised its option under the corporate headquarters lease and purchased the building at the expiration of the lease term for $49 million.

Refer to “Liquidity and Capital Resources” for additional details regarding financing developments.

STRATEGIC OVERVIEW

A summary of Alliant Energy’s, IPL’s and WPL’s strategic overview is included in the 2011 Form 10-K and has not changed materially from the items reported in the 2011 Form 10-K, except as described below.

Potential Natural Gas-Fired Generation Projects -

IPL’s Potential Construction of a Natural Gas-Fired Electric Generating Facility—IPL received numerous proposals in response to the RFP issued in January 2012 seeking firm long-term supplies of non-intermittent capacity and energy delivered to IPL’s control area. The RFP solicited ownership and/or long-term PPA proposals for either new or existing resources or access to a portion of the output of a portfolio of system resources. IPL is currently evaluating the proposals

from the RFP as part of the due diligence process for the potential construction of a new 600 MW natural gas-fired combined-cycle generating facility and expects to make a decision regarding its plans to meet the future demands of its customers in the third quarter of 2012.

WPL’s Potential Purchase of a Natural Gas-Fired Electric Generating Facility—In April 2012, the PSCW approved WPL’s CA application to acquire Riverside, a 600 MW natural gas-fired electric generating facility in Beloit, Wisconsin, for approximately $393 million by the end of 2012. WPL’s purchase of Riverside would replace the 490 MW of electricity output currently obtained from the Riverside PPA to meet the demand of its customers. Subject to receiving all remaining regulatory approvals including FERC and under the Hart—Scott—Rodino Act, WPL currently plans to complete the acquisition in December 2012.

Coal-Fired Generation Project -

WPL’s Nelson Dewey Generating Station—Nelson Dewey is a 208 MW electric generating facility located in Cassville, Wisconsin that includes two units (Unit 1 and Unit 2), which are configured to burn coal. In 2011, WPL filed documents with MISO to evaluate any system reliability implications of the eventual full retirement of Nelson Dewey. In March 2012, MISO indicated that the retirement of both units may result in reliability issues and that transmission upgrades are necessary to enable the retirement. Under the current MISO tariff, the specific timing for the retirement of Nelson Dewey Units 1 and 2 could depend on the timing of the required transmission upgrades and various operational, market and other factors.

Environmental Compliance Plans -

IPL’s Emission Control Projects—In April 2012, IPL and MidAmerican each filed an updated EPB with the IUB. IPL’s EPB includes emission control projects for Ottumwa Unit 1 and Lansing Unit 4. MidAmerican’s EPB includes emission control projects for George Neal Units 3 and 4. Alliant Energy and IPL currently expect the IUB to issue their decisions on IPL’s and MidAmerican’s EPBs by the end of 2012.

RATE MATTERS

A summary of Alliant Energy’s, IPL’s and WPL’s rate matters is included in the 2011 Form 10-K and has not changed materially from the items reported in the 2011 Form 10-K, except as described below.

(a) In Iowa, IPL’s interim rates can be implemented 10 days after the filing date, without regulatory review and are subject to refund, pending determination of final rates. In Minnesota, IPL’s interim rates can be implemented 60 days after the filing date, with regulatory review and subject to refund, pending determination of final rates. The amount of the interim rates is replaced by the amount of final rates once the final rates are granted.
(b) Base rate increases reflect both returns on additions to IPL’s infrastructure and recovery of changes in costs incurred or expected to be incurred by IPL. Given a portion of the rate increases will offset changes in costs, revenues from rate increases should not be expected to result in an equal increase in income.
(c) The final recovery amount for the Minnesota retail portion of IPL’s Whispering Willow—East wind project construction costs will be addressed in a separate proceeding that is currently expected to be completed in 2012.

Wisconsin Retail Electric and Gas Rate Case (2013/2014 Test Period)—In May 2012, after discussions with PSCW staff and major intervener groups, WPL filed a retail base rate filing based on a forward-looking test period that includes 2013 and 2014. The filing requests approval for WPL to implement a decrease in annual retail natural gas base rates of $13 million effective Jan. 1, 2013 followed by a freeze of such natural gas base rates through the end of 2014. The filing also requests authority to maintain customer base rates for WPL’s retail electric customers at their current levels through the end of 2014.

Table of Contents

Recovery of the costs for the planned acquisition of Riverside, the SCR project at Edgewater Unit 5 and the scrubber and baghouse projects at Columbia Units 1 and 2 are included in the request. The recovery of the costs for these capital projects are offset by decreases in rate base resulting from increased net deferred tax liabilities, the impact of amortizations of regulatory assets and regulatory liabilities, and the reduction of capacity payments. WPL’s May 2012 retail base rate filing included a return on common equity of 10.4% and the following related provisions: (1) WPL may request a change in retail base rates if its annual return on common equity falls below 8.5%; and (2) WPL must defer a portion of its earnings if its annual return on common equity exceeds 10.65%. The amount of earnings WPL must defer is equal to 50% of its excess earnings between 10.66% and 11.40% and 100% of any excess earnings above 11.40%. In addition, the filing requests WPL maintain its ability to request deferrals based on current practices. The retail base rate filing in May 2012 also included the following key assumptions (Common Equity (CE); Preferred Equity (PE); Long-term Debt (LD); Short-term Debt (SD); Weighted-average Cost of Capital (WACC); dollars in billions):

The fuel-related cost component of WPL’s retail electric rates for 2013 and 2014 will be addressed in separate filings. WPL currently expects to make retail fuel-related cost filings for 2013 and 2014 in the second or third quarters of 2012 and 2013, respectively.

IPL’s Minnesota Retail Electric Rate Case (2009 Test Year)—In May 2010, IPL filed a request with the Minnesota Public Utilities Commission (MPUC) to increase annual rates for its Minnesota retail electric customers. In conjunction with the filing, IPL implemented an interim retail rate increase of $14 million, on an annual basis, effective July 6, 2010. The interim retail rate increase was approved by the MPUC, subject to refund pending determination of final rates from the request. In November 2011, IPL received an order from the MPUC establishing a final annual retail electric rate increase equivalent to $11 million. The final annual retail electric rate increase of $11 million includes $8 million of higher base rates, $2 million from the temporary renewable energy rider and $1 million from the utilization of regulatory liabilities to offset higher electric transmission service costs. Because the final rate increase level was below the interim retail rate increase level implemented in July 2010, IPL began refunding a portion of the interim rates collected to its Minnesota retail electric customers in the first quarter of 2012. As of March 31, 2012, Alliant Energy and IPL reserved $3 million, including interest, for remaining refunds anticipated to be paid to IPL’s Minnesota retail electric customers in 2012.

IPL’s Iowa Retail Electric Rate Case (2009 Test Year)—In March 2010, IPL filed a request with the IUB to increase annual rates for its Iowa retail electric customers. In conjunction with the filing, IPL implemented an interim retail electric rate increase of $119 million, or approximately 10%, on an annual basis, effective March 20, 2010, without regulatory review and subject to refund pending determination of final rates. In February 2011, IPL received an order from the IUB authorizing a final annual retail electric rate increase of $114 million, or approximately 10%. Because the final rate increase level was below the interim rate increase level implemented in March 2010, IPL refunded to its Iowa retail customers $5 million in 2011.

Tax Benefit Rider—In January 2011, the IUB approved a tax benefit rider proposed by IPL in its Iowa retail electric rate case (2009 Test Year). The tax benefit rider, which was implemented in late February 2011, utilizes regulatory liabilities to credit bills of Iowa retail customers to help offset the impact of recent rate increases on such customers. These credits on customers’ electric bills reduce electric revenues each quarter based on customers’ kilowatt-hour usage, which is fairly consistent throughout each calendar year. The tax benefit rider also results in a reduction in income tax expense from the benefits of the tax initiatives. While the tax benefit rider is not expected to impact total year earnings, it does result in considerable quarterly variations in earnings due to the accounting rules for recording income taxes in interim financial statements. According to these rules, the offsetting tax benefits from the tax benefit rider are recorded based on the percentage of annual expected earnings each quarter, which fluctuates significantly causing considerable quarterly variation in the income tax benefits from the tax benefit rider. In the first quarters of 2012 and 2011, the quarterly variation in earnings from the tax benefit rider resulted in a net increase (decrease) in Alliant Energy’s earnings of ($3) million ($6 million at Alliant Energy’s parent company and ($9) million at IPL) and $5 million ($2 million at Alliant Energy’s parent company and $3 million at IPL), respectively. As stated previously, the quarterly variations in earnings from the tax benefit rider will offset each other for each calendar year resulting in no earnings impact for the full calendar years of 2012 and 2011.

Table of Contents

As of March 31, 2012, Alliant Energy’s and IPL’s remaining regulatory liabilities related to the tax benefit rider recognized were $329 million. The final amount of regulatory liabilities returned to customers under the tax benefit rider is dependent on the amount of tax benefits sustained under IRS audit and therefore is subject to change. Refer to Note 4 of the “Combined Notes to Condensed Consolidated Financial Statements” and “Results of Operations—Income Taxes” for additional discussion of the impact of the tax benefit rider on Alliant Energy’s and IPL’s income tax expense and effective income tax rates.

Planned Utility Rate Case in 2012 -

Iowa Retail Gas Rate Case (2011 Test Year)—IPL currently expects to file an Iowa retail gas rate case in the second quarter of 2012 based on a 2011 historical test period. The key drivers for the anticipated filing include recovery of increased costs and capital investments since IPL’s last Iowa gas retail rate case filed in 2005. Any rate changes are expected to be implemented in two phases with interim rates effective approximately 10 days after the filing and final rates effective approximately 11 months after the filing date. IPL currently expects to propose a tax benefit rider that will utilize regulatory liabilities generated from tax initiatives to credit bills of Iowa retail gas customers to partially offset any requested rate increase from this case.

WPL’s Retail Fuel-related Rate Filing -

2012 Test Year—In December 2011, WPL received an order from the PSCW authorizing an annual retail electric rate increase of $4 million related to expected changes in retail electric production fuel and energy purchases (fuel-related costs). The December 2011 order also required WPL to defer direct CSAPR compliance costs that are not included in the fuel monitoring level and set a zero percent tolerance band for the CSAPR-related deferral. The 2012 fuel costs, excluding deferred CSAPR compliance costs, will be monitored using an annual bandwidth of plus or minus 2%. The rate change granted from this request was effective Jan. 1, 2012.

ENVIRONMENTAL MATTERS

A summary of Alliant Energy’s, IPL’s and WPL’s environmental matters is included in the 2011 Form 10-K and has not changed materially from the items reported in the 2011 Form 10-K, except as described below.

Air Quality -

Air Permitting Violation Claims—Refer to Note 11(b) of the “Combined Notes to Condensed Consolidated Financial Statements” for discussion of complaints filed by the Sierra Club in 2010 and an NOV issued by the EPA in 2009 regarding alleged air permitting violations at Nelson Dewey, Columbia and Edgewater.

Water Quality -

Hydroelectric Fish Passages Device—In March 2012, FERC extended the deadline to install an agency-approved fish passage device at WPL’s Prairie du Sac hydro plant to July 1, 2015. Alliant Energy and WPL believe the required capital investments and/or modifications to install the fish passage device at the facility could be significant.

Land and Solid Waste -

MGP Sites—Refer to Note 11(d) of the “Combined Notes to Condensed Consolidated Financial Statements” for discussion of IPL’s and WPL’s MGP sites.

GHG Emissions -

EPA NSPS for GHG Emissions from Electric Utilities—In April 2012, the EPA published proposed NSPS for GHG, including CO2 emissions from new fossil-fueled EGUs larger than 25 MW with an output-based emissions rate limitation of 1,000 pounds of CO2 per MWh. This emissions rate limitation is expected to be effective upon the EPA’s issuance of the final rule in the second quarter of 2013. The proposed NSPS for new EGUs is expected to apply to IPL’s potential construction of a new 600 MW natural gas-fired combined-cycle electric generating facility in Iowa, which will be designed to achieve compliance with the proposed CO2 emissions rate limitation. The EPA announced the issuance of proposed regulations for existing EGUs will be delayed and has not yet established a new schedule. Alliant Energy, IPL and WPL are currently unable to predict with certainty the final outcome of this proposed standard, but expect that expenditures to comply with any regulations to reduce GHG emissions could be significant.

The most significant provisions of the SBJA and the Act for Alliant Energy, IPL and WPL were provisions related to the extension of bonus depreciation deductions for certain expenditures for property that are incurred through Dec. 31, 2012. Refer to Note 4 of the “Combined Notes to Condensed Consolidated Financial Statements” for further discussion of the SBJA and the Act, including estimated bonus depreciation deductions expected to be claimed on Alliant Energy’s 2012 U.S. federal income tax return.

ALLIANT ENERGY’S RESULTS OF OPERATIONS

Overview—First Quarter Results—Refer to “Executive Summary” for an overview of Alliant Energy’s first quarter 2012 and 2011 earnings and the various components of Alliant Energy’s business. Additional details of Alliant Energy’s earnings for the first quarters of 2012 and 2011 are discussed below.

Utility Electric MarginsElectric margins are defined as electric operating revenues less electric production fuel, energy purchases and purchased electric capacity expenses. Management believes that electric margins provide a more meaningful basis for evaluating utility operations than electric operating revenues since electric production fuel, energy purchases and purchased electric capacity expenses are generally passed through to customers, and therefore, result in changes to electric operating revenues that are comparable to changes in electric production fuel, energy purchases and purchased electric capacity expenses. Electric margins and MWh sales for Alliant Energy for the first quarter were as follows:

First Quarter 2012 vs. First Quarter 2011 Summary—Electric margins decreased $18 million, or 5%, primarily due to an estimated $16 million decrease in electric margins from changes in sales caused by weather conditions in Alliant Energy’s service territories and $13 million of decreased revenues due to higher credits on Iowa retail electric customers’ bills resulting from the tax benefit rider in the first quarter of 2012 compared to the same period in 2011. Other decreases to electric margins included $2 million of higher purchased electric capacity expenses at WPL related to the Kewaunee PPA and $2 million of lower energy conservation revenues at IPL. Estimated increases (decreases) to Alliant Energy’s electric margins from the impacts of weather during the first quarters of 2012 and 2011 were ($12) million and $4 million, respectively. IPL’s tax benefit rider is expected to result in reductions in electric revenues that are offset by reductions in income tax expense for the year ended Dec. 31, 2012. Changes in energy conservation revenues were largely offset by changes in energy conservation expenses included in other operation and maintenance expenses. These items were partially offset by $6 million of higher revenues at IPL related to changes in recovery mechanisms for transmission costs due to the transmission rider implemented in the first quarter of 2011, a $5 million increase in electric margins from changes in the recovery of electric production fuel and energy purchases expenses at WPL and an increase in weather-normalized sales volumes at both IPL and WPL. The higher transmission rider revenues were offset by higher electric transmission service expenses.

Weather Conditions—Temperatures during the first quarter of 2012 were 20% to 25% warmer than normal, as measured by heating degree days (HDD) in Alliant Energy’s service territories. These warmer temperatures caused a significant decrease in IPL’s and WPL’s electric and gas sales due to the lack of demand by customers for heating. Cooling degree days (CDD) were also calculated in Alliant Energy’s service territories in the first quarter of 2012. These CDD caused a modest increase in electric sales related to demand by customers for air conditioning usage. HDD and CDD in Alliant Energy’s service territories for the first quarter were as follows:

(a) HDD and CDD are calculated using a simple average of the high and low temperatures each day compared to a 65-degree base. Normal degree days are calculated using a rolling 20-year average of historical HDD and CDD.

Electric Production Fuel and Energy Purchases (Fuel-related) Cost Recoveries—Alliant Energy burns coal and other fossil fuels to produce electricity at its generating facilities. The cost of fossil fuels used during each period is included in electric production fuel expense. Alliant Energy also purchases electricity to meet the demand of its customers and charges these costs to energy purchases expense. Alliant Energy’s electric production fuel expense decreased $39 million, or 36%, in the first quarter of 2012. The decrease was primarily due to lower MISO dispatch of Alliant Energy’s generating facilities in the first quarter of 2012, which resulted in lower fuel consumption. Alliant Energy’s energy purchases expense increased $5 million, or 6%, in the first quarter of 2012. The increase was primarily due to higher energy volumes purchased resulting from the lower MISO dispatch of Alliant Energy’s generating facilities in the first quarter of 2012, largely offset by lower energy prices. The impact of changes in electricity volumes generated from Alliant Energy’s generating facilities was largely offset by the impact of the changes in energy volumes purchased and changes in bulk power sales volumes discussed below.

Due to IPL’s rate recovery mechanisms for fuel-related costs, changes in fuel-related costs resulted in comparable changes in electric revenues and, therefore, did not have a significant impact on IPL’s electric margins. WPL’s rate recovery mechanism for wholesale fuel-related costs also provides for adjustments to its wholesale electric rates for changes in commodity costs, thereby mitigating impacts of changes to commodity costs on its electric margins.

WPL’s retail fuel-related costs incurred during the first quarter of 2012 were lower than the forecasted fuel-related costs used to set retail rates during such period. WPL estimates the lower than forecasted retail fuel-related costs increased electric margins by approximately $1 million during the first quarter of 2012. WPL’s retail fuel-related costs incurred during the first quarter of 2011 were higher than the forecasted fuel-related costs used to set retail rates during such period. WPL estimates the higher than forecasted retail fuel-related costs decreased electric margins by approximately $4 million during the first quarter of 2011.

Purchased Electric Capacity Expenses—Alliant Energy enters into PPAs to help meet the electricity demand of IPL’s and WPL’s customers. Certain of these PPAs include minimum payments for IPL’s and WPL’s rights to electric generating capacity. Details of purchased electric capacity expense included in the utility electric margins table above for the first quarter were as follows (in millions):

Sales Trends—Retail sales volumes decreased 1% in the first quarter of 2012 compared to the same period in 2011, primarily due to warmer weather conditions in Alliant Energy’s service territories. This item was largely offset by higher sales to industrial customers driven by increased production requirements and an extra day of sales due to the leap year.

Wholesale sales volumes decreased 10% in the first quarter of 2012 compared to the same period in 2011, primarily due to the impact of weather conditions and changes in sales to WPL’s partial-requirement wholesale customers that have contractual options to be served by WPL, other power supply sources or the MISO market.

Bulk power and other revenue changes were largely due to changes in revenues from sales in the wholesale energy markets operated by MISO and PJM Interconnection, LLC. These changes are impacted by several factors including the availability of Alliant Energy’s generating facilities and electricity demand within these wholesale energy markets. Changes in bulk power and other sales revenues were offset by changes in fuel-related costs and therefore did not have a significant impact on electric margins.

Utility Gas MarginsGas margins are defined as gas operating revenues less cost of gas sold. Management believes that gas margins provide a more meaningful basis for evaluating utility operations than gas operating revenues since cost of gas sold is generally passed through to customers, and therefore results in changes to gas operating revenues that are comparable to changes in cost of gas sold. Gas margins and Dth sales for Alliant Energy for the first quarter were as follows:

 

     Revenues and Costs (dollars in millions)     Dths Sold (Dths in thousands)  
     2012      2011      Change     2012      2011      Change

First Quarter 2012 vs. First Quarter 2011 Summary—Gas margins decreased $10 million, or 14%, primarily due to an estimated $13 million decrease in gas margins from changes in sales caused by weather conditions in Alliant Energy’s service territories. Estimated increases (decreases) to Alliant Energy’s gas margins from the impacts of weather during the first quarters of 2012 and 2011 were ($10) million and $3 million, respectively.

Refer to “Utility Electric Margins” for details of Alliant Energy’s HDD data. Refer to “Rate Matters” for discussion of retail rate cases.

Utility Other Revenues—Other revenues for the utilities decreased $3 million primarily due to lower coal sales at IPL during the first quarter of 2012 as compared to the first quarter of 2011. Changes in utility other revenues were largely offset by related changes in utility other operation and maintenance expenses.

Electric Transmission Service Expense—Alliant Energy’s electric transmission service expense for the utilities increased $8 million primarily due to higher transmission costs at IPL related to transmission services from ITC Midwest LLC (ITC). The increase was primarily due to $2 million of higher electric transmission service costs billed by ITC to IPL in the first quarter of 2012 compared to the first quarter of 2011 due to a modest increase in transmission service rates and the impact of IPL utilizing $5 million of regulatory liabilities to credit a portion of the transmission service expenses billed to IPL by ITC during the first quarter of 2011. Alliant Energy currently estimates electric transmission service expenses related to ITC will be approximately $30 million to $35 million higher in 2012 compared to 2011. This estimate is impacted by monthly peak demands. IPL is currently recovering the Iowa retail portion of these increased electric transmission service costs from its retail electric customers in Iowa through the transmission cost rider resulting in an offsetting increase in electric revenues.

Preferred Dividend Requirements of Subsidiaries—Preferred dividend requirements of subsidiaries decreased $2 million due to a $2 million charge in the first quarter of 2011 related to IPL’s redemption of its 7.10% Series C Cumulative Preferred Stock in 2011.

IPL’S RESULTS OF OPERATIONS

Overview—First Quarter Results—Earnings available for common stock decreased $26 million primarily due to lower electric and gas margins resulting from the impacts of weather in the first quarter of 2012 and increased credits on retail electric customers’ bills in Iowa from the tax benefit rider, and tax charges in the first quarter of 2012 resulting from changes in state apportionment projections caused by Alliant Energy’s planned sale of the RMT business.

First Quarter 2012 vs. First Quarter 2011 Summary—Electric margins decreased $16 million, or 8%, primarily due to $13 million of decreased revenues in the first quarter of 2012 due to additional credits on Iowa retail electric customers’ bills resulting from the tax benefit rider and an estimated $11 million decrease in electric margins from changes in sales caused by weather conditions in IPL’s service territory. Electric margins were also decreased by $2 million of lower energy conservation revenues. IPL’s tax benefit rider is expected to result in reductions in electric revenues that are offset by reductions in income tax expenses for the year ended Dec. 31, 2012. Estimated increases (decreases) to IPL’s electric margins from the impacts of weather during the first quarters of 2012 and 2011 were ($8) million and $3 million, respectively. Changes in energy conservation revenues were largely offset by changes in energy conservation expenses included in other operation and maintenance expenses. These items were partially offset by $6 million of higher revenues related to changes in recovery mechanisms for transmission costs due to the transmission rider and an increase in weather-normalized retail sales volumes. The higher transmission rider revenues were offset by higher electric transmission service expenses.

Refer to “Alliant Energy’s Results of Operations—Utility Electric Margins” for details on IPL’s HDD and CDD data, purchased electric capacity expenses, recoveries of electric production fuel and energy purchases expenses and sales trends.

Gas MarginsGas margins are defined as gas operating revenues less cost of gas sold. Management believes that gas margins provide a more meaningful basis for evaluating utility operations than gas operating revenues since cost of gas sold is generally passed through to customers, and therefore, results in changes to gas operating revenues that are comparable to changes in cost of gas sold.

Steam and Other RevenuesSteam and other revenues decreased $3 million primarily due to lower coal sales during the first quarter of 2012 as compared to the first quarter of 2011. Changes in steam and other revenues were largely offset by related changes in other operation and maintenance expenses.

Electric Transmission Service Expense—Electric transmission service expense increased $8 million primarily due to higher transmission costs related to transmission services from ITC. The increase was primarily due to $2 million of higher electric transmission service costs billed by ITC to IPL in the first quarter of 2012 compared to the first quarter of 2011 due to a modest increase in transmission service rates and the impact of IPL utilizing $5 million of regulatory liabilities to credit a portion of the transmission service expenses billed to IPL by ITC during the first quarter of 2011. IPL currently estimates electric transmission service expenses related to ITC will be approximately $30 million to $35 million higher in 2012 compared to 2011. This estimate is impacted by monthly peak demands. IPL is currently recovering the Iowa retail portion of these increased electric transmission service costs from its retail electric customers in Iowa through the transmission cost rider resulting in an offsetting increase in electric revenues.

Other Operation and Maintenance ExpensesOther operation and maintenance expenses decreased $10 million primarily due to $2 million of lower generation operation and maintenance expenses resulting from the timing of maintenance projects, $2 million of lower energy conservation expenses, $2 million of lower expenses related to coal sales and decreases in other administrative and general expenses. Changes in energy conservation expenses were largely offset by changes in energy conservation revenues included in electric and gas margins. Changes in expenses related to coal sales were largely offset by changes in steam and other revenues.

Refer to “Alliant Energy’s Results of Operations—Utility Other Operation and Maintenance Expenses” for additional details of IPL’s other operation and maintenance expenses.

Depreciation and Amortization ExpensesDepreciation and amortization expenses increased $3 million primarily due to higher depreciation rates during the first quarter of 2012 as compared to the same period in 2011 resulting from IPL’s most recent depreciation study and property additions.

Income TaxesDetails of IPL’s effective income tax rates during the first quarter were as follows. The overall income tax rate for the first quarter of 2012 is not meaningful given the impact of IPL’s low income before income taxes for such period.

Preferred Dividend Requirements—Preferred dividend requirements decreased $2 million due to a $2 million charge in the first quarter of 2011 related to IPL’s redemption of its 7.10% Series C Cumulative Preferred Stock in 2011.

WPL’S RESULTS OF OPERATIONS

Overview—First Quarter ResultsWPL’s earnings available for common stock decreased $13 million primarily due to tax charges in the first quarter of 2012 resulting from changes in state apportionment projections caused by Alliant Energy’s planned sale of the RMT business and lower electric and gas margins resulting from the impacts of weather in the first quarter of 2012. These items were partially offset by a $5 million wind site impairment charge recorded in the first quarter of 2011.

Electric MarginsElectric margins are defined as electric operating revenues less electric production fuel, energy purchases and purchased electric capacity expenses. Management believes that electric margins provide a more meaningful basis for evaluating utility operations than electric operating revenues since electric production fuel, energy purchases and purchased

First Quarter 2012 vs. First Quarter 2011 Summary—Electric margins decreased $1 million, or 1%, primarily due to an estimated $5 million decrease in electric margins from changes in sales caused by weather conditions in WPL’s service territory and $2 million of higher purchased electric capacity expenses related to the Kewaunee PPA. Estimated increases (decreases) to WPL’s electric margins from the impacts of weather during the first quarters of 2012 and 2011 were ($4) million and $1 million, respectively. These items were largely offset by a $5 million increase in electric margins from changes in the recovery of electric production fuel and energy purchases expenses and an increase in weather-normalized sales volumes.

Refer to “Alliant Energy’s Results of Operations—Utility Electric Margins” for details of WPL’s HDD and CDD data, purchased electric capacity expenses, recoveries of electric production fuel and energy purchases expenses and sales trends.

Gas MarginsGas margins are defined as gas operating revenues less cost of gas sold. Management believes that gas margins provide a more meaningful basis for evaluating utility operations than gas operating revenues since cost of gas sold is generally passed through to customers, and therefore, results in changes to gas operating revenues that are comparable to changes in cost of gas sold. Gas margins and Dth sales for WPL for the first quarter were as follows:

Other Operation and Maintenance ExpensesOther operation and maintenance expenses decreased $1 million primarily due to a $5 million wind site impairment charge recorded in the first quarter of 2011. This item was largely offset by higher other administrative and general expenses.

Refer to “Alliant Energy’s Results of Operations—Utility Other Operation and Maintenance Expenses” for additional details of WPL’s other operation and maintenance expenses.

Depreciation and Amortization Expenses—Depreciation and amortization expenses increased $2 million primarily due to property additions including higher depreciation expense recognized in the first quarter of 2012 related to the Bent Tree—Phase I wind project.

Operating Activities -

First Quarter 2012 vs. First Quarter 2011—Alliant Energy’s cash flows from operating activities decreased $46 million primarily due to lower cash flows resulting from higher inventory levels of production fuel in the first quarter of 2012, decreased collections from IPL’s and WPL’s customers in the first quarter of 2012 caused by the weather impacts on electric and gas retail sales, the timing of fuel-cost recoveries at IPL and $13 million of higher credits on retail electric customers’ bills in Iowa in the first quarter of 2012 resulting from IPL’s tax benefit rider. These items were partially offset by $54 million of higher cash flows from operations at RMT due to decreased working capital requirements associated with renewable energy projects in 2012 and 2011.

IPL’s cash flows from operating activities decreased $50 million primarily due to the timing of fuel-cost recoveries, lower cash flows resulting from higher inventory levels of production fuel in the first quarter of 2012, decreased collections from IPL’s customers in the first quarter of 2012 caused by the weather impacts on electric and gas retail sales and $13 million of higher credits on retail electric customers’ bills in Iowa in the first quarter of 2012 resulting from the tax benefit rider. These items were partially offset by $36 million of higher cash flows from income tax refunds in the first quarter of 2012 and income tax payments in the first quarter of 2011.

WPL’s cash flows from operating activities decreased $79 million primarily due to $45 million of lower cash flows from income tax payments in the first quarter of 2012 and income tax refunds in the first quarter of 2011, lower cash flows resulting from higher inventory levels of production fuel in the first quarter of 2012 and decreased collections from WPL’s customers during the first quarter of 2012 caused by the weather impacts on electric and gas retail sales.

Production Fuel—MISO’s dispatch of Alliant Energy’s generating facilities impacts the amount of production fuel used each period at IPL and WPL. In the first quarter of 2012, lower MISO dispatch of Alliant Energy’s generating facilities resulted in lower production fuel used, which contributed to increased production fuel inventory levels at IPL and WPL. Production fuel inventory levels at IPL and WPL decreased significantly in the first quarter of 2011 due to higher dispatch of Alliant Energy’s generating facilities during such period. The changes in production fuel inventory levels during the first quarters of 2012 and 2011 resulted in a decrease to Alliant Energy’s, IPL’s and WPL’s cash flows from operations of $42 million, $22 million and $20 million, respectively.

Weather Impacts—Refer to “Alliant Energy’s Results of Operations,” “IPL’s Results of Operations” and “WPL’s Results of Operations” for discussion of weather impacts on electric and gas retail sales in the first quarter of 2012 compared to the first quarter of 2011.

RMT’s Working Capital Requirements—Cash flows from operations at RMT can fluctuate significantly from period to period based on the timing of cash receipts from customers and cash payments for construction activities associated with its customers’ large renewable energy projects. Cash flows from operations at RMT increased significantly in the first quarter of 2012 compared to the first quarter of 2011 largely due to amounts collected in 2012 for customers’ large renewable projects completed in late 2011 and early 2012. In February 2012, Alliant Energy announced plans to sell RMT in 2012.

IPL’s Tax Benefit Rider—In January 2011, the IUB approved a tax benefit rider proposed by IPL, which utilizes regulatory liabilities created with tax benefits from changes in accounting methodologies and tax elections available under the Internal Revenue Code to credit bills of Iowa retail electric customers. In the first quarters of 2012 and 2011, IPL credited $20 million and $7 million, respectively, to customers’ bills under the tax benefit rider. Alliant Energy and IPL currently expect approximately $81 million of credits to IPL’s customers’ bills in 2012 under the tax benefit rider. Refer to Note 4 of the “Combined Notes to Condensed Consolidated Financial Statements” for further discussion of IPL’s tax benefit rider.

Investing Activities -

First Quarter 2012 vs. First Quarter 2011—Alliant Energy’s cash flows used for investing activities decreased $98 million primarily due to $102 million of lower construction and acquisition expenditures. The lower construction and acquisition expenditures resulted from progress payments by IPL in the first quarter of 2011 for wind turbine generators that were sold to Resources in June 2011, and expenditures during the first quarter of 2011 for WPL’s Bent Tree—Phase I wind project and WPL’s acquisition of the remaining 25% interest in Edgewater Unit 5. These items were partially offset by expenditures during the first quarter of 2012 for emission controls projects at WPL’s Columbia Units 1 and 2, IPL’s Ottumwa Unit 1 and IPL’s George Neal Units 3 and 4.

IPL’s cash flows used for investing activities decreased $48 million primarily due to $48 million of lower construction expenditures. The lower construction expenditures resulted from progress payments in the first quarter of 2011 for wind turbine generators that were sold to Resources in June 2011. This item was partially offset by expenditures during the first quarter of 2012 for the emission controls projects at Ottumwa Unit 1 and George Neal Units 3 and 4.

WPL’s cash flows used for investing activities decreased $61 million primarily due to $59 million of lower construction and acquisition expenditures. The lower construction and acquisition expenditures resulted from expenditures during the first quarter of 2011 for the Bent Tree—Phase I wind project and the Edgewater Unit 5 purchase. These items were partially offset by expenditures during the first quarter of 2012 for emission controls projects at Columbia Units 1 and 2.

Construction and Acquisition Expenditures—Currently, there are no material changes to Alliant Energy’s, IPL’s and WPL’s anticipated construction and acquisition expenditures from those reported in the 2011 Form 10-K.

Government Incentives for Wind Projects—Alliant Energy, IPL and WPL evaluated their options for government incentive elections for IPL’s Whispering Willow—East wind project and WPL’s Bent Tree—Phase I wind project and currently believe they will continue with the production tax credits incentive election for those two wind projects. Refer to “Other Matters—Other Future Considerations” for further discussion of government incentives for wind projects.

Financing Activities -

First Quarter 2012 vs. First Quarter 2011—Alliant Energy’s cash flows used for financing activities decreased $1 million primarily due to changes in cash overdrafts attributable to outstanding checks that have not yet cleared the bank, largely offset by changes in the amount of commercial paper outstanding at Alliant Energy, IPL and WPL.

IPL’s cash flows from financing activities increased $25 million primarily due to changes in the amount of commercial paper outstanding and changes in cash overdrafts attributable to outstanding checks that have not yet cleared the bank.

WPL’s cash flows used for financing activities decreased $17 million primarily due to changes in the amount of commercial paper outstanding and changes in cash overdrafts attributable to outstanding checks that have not yet cleared the bank.

FERC Financing Authorizations—In March 2012, FERC authorized Corporate Services to issue up to $150 million in long-term debt securities and to maintain up to $200 million in short-term debt securities outstanding (including borrowings from its parent or other affiliates) during the period from March 31, 2012 through March 30, 2014. FERC also authorized Corporate Services to receive an unspecified amount of capital contributions and advances from its parent or other affiliates during the period from March 31, 2012 through March 30, 2014.

Common Stock Issuances and Capital Contributions—Refer to Note 5(b) of the “Combined Notes to Condensed Consolidated Financial Statements” for discussion of Alliant Energy’s common stock issuances during the first quarter of 2012 under its equity incentive plans for employees. Refer to Note 6 of the “Combined Notes to Condensed Consolidated Financial Statements” for discussion of payments of common stock dividends by IPL and WPL to their parent company in the first quarter of 2012.

Short-term Debt—Alliant Energy’s, IPL’s and WPL’s credit facility agreements each contain a covenant, which requires the entities to maintain certain debt-to-capital ratios in order to borrow under the credit facilities. The required debt-to-capital ratios compared to the actual debt-to-capital ratios at March 31, 2012 were as follows:

 

     Alliant Energy   IPL   WPL

Requirement

   Less than 65%   Less than 58%   Less than 58%

Status at March 31, 2012

OTHER MATTERS

Market Risk Sensitive Instruments and PositionsAlliant Energy’s, IPL’s and WPL’s primary market risk exposures are associated with commodity prices, investment prices and interest rates. Alliant Energy, IPL and WPL have risk management policies to monitor and assist in mitigating these market risks and use derivative instruments to manage some of the exposures. A summary of Alliant Energy’s, IPL’s and WPL’s market risks is included in the 2011 Form 10-K and such market risks have not changed materially from those reported in the 2011 Form 10-K.

Critical Accounting Policies and EstimatesA summary of Alliant Energy’s, IPL’s and WPL’s critical accounting policies and estimates is included in the 2011 Form 10-K and such policies and estimates have not changed materially from those reported in the 2011 10-K, except as described below.

Contingencies—Alliant Energy, IPL and WPL make assumptions and judgments each reporting period regarding the future outcome of contingent events and record loss contingency amounts for any contingent events that are both probable and reasonably estimated based upon current available information. Note 11 of the “Combined Notes to Condensed Consolidated Financial Statements” provides discussion of contingencies assessed at March 31, 2012 including various pending legal proceedings that may have a material impact on Alliant Energy’s, IPL’s and WPL’s financial condition and results of operations.

Regulatory Assets and Regulatory Liabilities—Alliant Energy, IPL and WPL make assumptions and judgments each reporting period regarding whether their regulatory assets are probable of future recovery and their regulatory liabilities are probable future obligations. Note 1(b) of the “Combined Notes to Condensed Consolidated Financial Statements” provides details of the nature and amounts of Alliant Energy’s, IPL’s and WPL’s regulatory assets and regulatory liabilities assessed at March 31, 2012 as well as material changes to Alliant Energy’s and IPL’s regulatory liabilities during the first quarter of 2012. Material changes to these regulatory liabilities during the first quarter of 2012 were largely due to IPL’s tax benefit rider, which utilized $20 million of regulatory liabilities to credit IPL’s Iowa retail electric customers’ bills in the first quarter of 2012.

Long-Lived Assets—Alliant Energy, IPL and WPL complete periodic assessments regarding the recoverability of certain long-lived assets when factors indicate the carrying value of such assets may be impaired or such assets are planned to be sold. These assessments require significant assumptions and judgments by management. The long-lived assets assessed for impairment generally include assets within their non-regulated operations, which are proposed to be sold or are not yet generating cash flows, and assets within their regulated operations, which may not be fully recovered from IPL’s and WPL’s customers as a result of regulatory decisions in the future. Alliant Energy’s long-lived assets within its non-regulated operations assessed in 2012 included the RMT business.

Long-Lived Assets Held for Sale—RMT—In February 2012, Alliant Energy announced plans to sell RMT in 2012. As a result, in the first quarter of 2012 Alliant Energy reclassified the RMT assets and liabilities into held for sale and its results of operations into discontinued operations. Alliant Energy performed an assessment of the carrying value of the RMT net assets held for sale as of March 31, 2012 and concluded that the forecasted selling price for the RMT business, less costs to sell, exceeded its carrying value. The forecasted selling price of RMT was estimated based upon current market information including information from recently negotiated deals in the construction industry and estimated transactional multiples from such deals. A change in the forecasted selling price could result in an impairment charge. As of March 31, 2012, the carrying

value of Alliant Energy’s RMT business was approximately $8 million. If Alliant Energy concludes the sale of RMT is no longer probable, it may be required to reclassify the accounting for the RMT business from assets and liabilities held for sale and discontinued operations back to continuing operations. Refer to Note 13 of the “Combined Notes to Condensed Consolidated Financial Statements” for further information regarding the RMT business.

Unbilled Revenues—Alliant Energy, IPL and WPL make assumptions and judgments each reporting period to estimate their amount of unbilled revenues. At March 31, 2012, unbilled revenues related to Alliant Energy’s utility operations were $111 million ($49 million at IPL and $62 million at WPL). Note 3 of the “Combined Notes to Condensed Consolidated Financial Statements” provides discussion of IPL’s unbilled revenues as of March 31, 2012 sold to a third-party financial institution related to its sales of accounts receivable program.

Pensions and Other Postretirement Benefits—Alliant Energy, IPL and WPL make assumptions and judgments periodically to estimate the obligations and costs related to their retirement plans. Note 5(a) of the “Combined Notes to Condensed Consolidated Financial Statements” provides additional details of pension and other postretirement benefits plans. Note 11(b) of the “Combined Notes to Condensed Consolidated Financial Statements” provides recent developments of the class action lawsuit filed against the Cash Balance Plan in 2008.

Income Taxes—Alliant Energy, IPL and WPL make assumptions and judgments each reporting period to estimate their income tax assets, liabilities, benefits and expenses. Alliant Energy’s, IPL’s and WPL’s critical assumptions and judgments include projections of future taxable income used to determine their ability to utilize net operating loss and credit carryforwards prior to their expiration and the states in which such future taxable income will be apportioned.

Carryforward Utilization—Alliant Energy, IPL and WPL generated significant federal tax credits and federal and state net operating losses that are currently being carried forward. Based on current projections of future taxable income, Alliant Energy, IPL and WPL plan to utilize substantially all of these carryforwards prior to their expiration. Changes in assumptions regarding Alliant Energy’s, IPL’s and WPL’s future taxable income could require valuation allowances in the future resulting in a material impact on their financial condition and results of operations. Refer to Note 4 of the “Combined Notes to Condensed Consolidated Financial Statements” for additional information on federal tax credit and federal and state net operating loss carryforwards as of March 31, 2012.

State Apportionment—Alliant Energy, IPL and WPL utilize state apportionment projections to record their deferred tax assets and liabilities each reporting period. Deferred tax assets and liabilities for temporary differences between the tax basis of assets and liabilities and the amounts reported in the consolidated financial statements are recorded utilizing currently enacted tax rates and estimates of future state apportionment rates expected to be in effect at the time the temporary differences reverse. These state apportionment projections are most significantly impacted by the estimated amount of revenues expected in the future from each state jurisdiction for Alliant Energy’s consolidated tax group, including both its regulated operations and its non-regulated operations. Alliant Energy, IPL and WPL recorded $15 million, $8 million and $7 million, respectively, of income tax expense in the first quarter of 2012 due to changes in state apportionment projections caused by the planned sale of Alliant Energy’s RMT business. A significant majority of the additional income tax expense recognized from changes in state apportionment projections were recorded at IPL and WPL due to their large deferred tax liability positions at March 31, 2012. Refer to Note 4 of the “Combined Notes to Consolidated Financial Statements” for further discussion of state apportionment impacts in the first quarter of 2012.

Other Future Considerations—A summary of Alliant Energy’s, IPL’s and WPL’s other future considerations is included in the 2011 Form 10-K and such considerations have not changed materially from the items reported in the 2011 Form 10-K, except as described below.

Government Incentives for Wind Projects—In December 2011, the National Defense Authorization Act (NDAA) was enacted. As a result, utilities are no longer subject to a tax normalization violation if they provide the benefits of the government grant incentive to their customers over a shorter time period than the regulatory life of the project assets. This provision of the NDAA can be applied retroactively to renewable energy projects placed into service since 2009. As a result of the enactment of NDAA, Alliant Energy, IPL and WPL evaluated their options for government incentive elections for IPL’s Whispering Willow—East wind project and WPL’s Bent Tree—Phase I wind project and currently believe they will continue with the production tax credits incentive election for those two wind projects. Alliant Energy currently expects to elect the government grant equal to 30% of the qualified cost basis of its Franklin County wind project scheduled to be completed by the end of 2012.

Quantitative and Qualitative Disclosures About Market Risk are reported in “Other Matters—Market Risk Sensitive Instruments and Positions” in MDA.

 

ITEM 4. CONTROLS AND PROCEDURES

Alliant Energy’s, IPL’s and WPL’s management evaluated, with the participation of each of Alliant Energy’s, IPL’s and WPL’s Chief Executive Officer (CEO), Chief Financial Officer (CFO) and Disclosure Committee, the effectiveness of the design and operation of Alliant Energy’s, IPL’s and WPL’s disclosure controls and procedures (as defined in Rule 13a-15(e) of the Securities Exchange Act of 1934) as of March 31, 2012 pursuant to the requirements of the Securities Exchange Act of 1934. Based on their evaluation, the CEO and the CFO concluded that Alliant Energy’s, IPL’s and WPL’s disclosure controls and procedures were effective as of March 31, 2012.

There was no change in Alliant Energy’s, IPL’s and WPL’s internal control over financial reporting that occurred during the quarter ended March 31, 2012 that has materially affected, or is reasonably likely to materially affect, Alliant Energy’s, IPL’s or WPL’s internal control over financial reporting.

PART II—OTHER INFORMATION

 

ITEM 1. LEGAL PROCEEDINGS

WPL -

Air Permitting Violation ClaimsIn September 2010, Sierra Club filed in the U.S. District Court for the Western District of Wisconsin a complaint against WPL, as owner and operator of Nelson Dewey and Columbia, based on allegations that modifications were made at the facilities without complying with the PSD program requirements, Title V Operating Permit requirements of the CAA and state regulatory counterparts contained within the Wisconsin SIP designed to implement the CAA. In October 2010, WPL responded to these claims related to Nelson Dewey and Columbia by filing with the U.S. District Court an answer denying the Columbia allegations and a motion to dismiss the Nelson Dewey allegations based on statute of limitations arguments. In November 2010, WPL filed a motion to dismiss the Nelson Dewey and Columbia allegations based on lack of jurisdiction. Sierra Club has responded to the motions. In January 2012, the Court reset the trial date to Dec. 10, 2012 and scheduled a status conference for Feb. 15, 2012 to receive an update on settlement progress. At the Feb. 15, 2012 status conference, the Court reaffirmed the Dec. 10, 2012 trial date and set a pre-trial schedule that allows the parties to work toward settlement.

In September 2010, Sierra Club filed in the U.S. District Court for the Eastern District of Wisconsin a complaint against WPL, as owner and operator of Edgewater, which contained similar allegations regarding air permitting violations at Edgewater. In the Edgewater complaint, additional allegations were made regarding violations of emission limits for visible emissions. In February 2011, WPL responded to these claims related to Edgewater by filing with the U.S. District Court an answer denying the allegations and a motion to dismiss the allegations based on lack of jurisdiction. In December 2011, the Court stayed all discovery and scheduling deadlines for 60 days (through Feb. 15, 2012) so that the Parties may continue settlement negotiations. In February 2012, the Court extended the stay. In April 2012, WPL and Sierra Club filed a joint settlement status report requesting the Court to stay all case management deadlines and agreeing to file a settlement status report by July 15, 2012, if no consent decree is filed by that date. WPL and Sierra Club are currently engaged in settlement discussions regarding the Nelson Dewey, Columbia and Edgewater air permitting violation claims.

In 2009, the EPA sent an NOV to WPL as an owner and the operator of Edgewater, Nelson Dewey and Columbia. The NOV alleges that the owners failed to comply with appropriate pre-construction review and permitting requirements and as a result violated the PSD program requirements, Title V Operating Permit requirements of the CAA and the Wisconsin SIP. WPL is engaged in settlement negotiations with the EPA in conjunction with the settlement negotiations with the Sierra Club discussed above.

In response to similar EPA CAA enforcement initiatives, certain utilities have elected to settle with the EPA, while others have elected to litigate. If the EPA and/or Sierra Club successfully prove their claims that projects completed in the past at Edgewater, Nelson Dewey and Columbia required either a state or federal CAA permit, WPL may, under the applicable statutes, be required to pay civil penalties in amounts of up to $37,500 per day for each violation and/or complete actions for injunctive relief. Payment of fines and/or injunctive relief could be included in a settlement outcome. Injunctive relief contained in settlements or court-ordered remedies for other utilities required the installation of emission control technology,

changed operating conditions including use of alternative fuels other than coal, caps for emissions and limitations on generation including retirement of generating units, and other beneficial environmental projects. If similar remedies are required for final resolution of these matters at Edgewater, Nelson Dewey and Columbia, Alliant Energy and WPL would incur additional capital and operating expenditures. Alliant Energy and WPL are continuing to analyze the allegations and are unable to predict the impact of the allegations on their financial condition or results of operations, but believe that the outcome could be significant. WPL and the other owners of Edgewater and Columbia are exploring settlement options while simultaneously defending against these allegations. Alliant Energy and WPL believe the projects at Edgewater, Nelson Dewey and Columbia were routine or not projected to increase emissions and therefore did not violate the permitting requirements of the CAA.

 

ITEM 1A. RISK FACTORS

A summary of Alliant Energy’s, IPL’s and WPL’s risk factors is included in Item 1A in the 2011 Form 10-K and such risk factors have not changed materially from the items reported in the 2011 Form 10-K.
