ALLIANT ENERGY CORPORATION
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

1.

The interim condensed consolidated financial statements included herein have been prepared by Alliant Energy, without audit, pursuant to the rules and regulations of the SEC. Accordingly, certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted, although management believes that the disclosures are adequate to make the information presented not misleading. The condensed consolidated financial statements include Alliant Energy and its consolidated subsidiaries (including IP&L, WP&L, Resources and Corporate Services). These financial statements should be read in conjunction with the financial statements and the notes thereto included in Alliant Energy’s, IP&L’s and WP&L’s latest combined Annual Report on Form 10-K.


  In the opinion of management, all adjustments, which are normal and recurring in nature, necessary for a fair presentation of (a) the condensed consolidated results of operations for the three and six months ended June 30, 2004 and 2003 (b) the condensed consolidated financial position at June 30, 2004 and Dec. 31, 2003, and (c) the condensed consolidated statements of cash flows for the six months ended June 30, 2004 and 2003 have been made. Because of the seasonal nature of Alliant Energy’s utility operations, results for the three and six months ended June 30, 2004 are not necessarily indicative of results that may be expected for the year ending Dec. 31, 2004. Certain prior period amounts have been reclassified on a basis consistent with the current period presentation.

The provisions for income taxes for earnings from continuing operations are based on the estimated annual effective tax rate, which differs from the federal statutory rate of 35% principally due to state income taxes, the impact of foreign income and associated taxes, tax credits, effects of utility rate making and certain non-deductible expenses. The provisions for income taxes from continuing operations for the three and six months ended June 30, 2004 were also significantly different from the federal statutory rate of 35% due to the goodwill impairment charge recorded in the second quarter of 2004. Alliant Energy anticipates a significant portion of the temporary difference resulting from the goodwill impairment charge will more likely than not reverse in the form of a capital loss for tax purposes. Given Alliant Energy’s current capital loss carryforward position and the likelihood regarding its ability to utilize the capital loss related to this goodwill impairment charge before it expires, Alliant Energy recorded a valuation allowance against deferred tax assets of approximately $14 million in the second quarter of 2004 related to this issue.

Alliant Energy utilizes derivative instruments to manage its exposures to various market risks as described in Alliant Energy’s, IP&L’s and WP&L’s combined Annual Report on Form 10-K for the year ended Dec. 31, 2003. The following information supplements, and should be read in conjunction with, Note 10(a) in Alliant Energy’s “Notes to Consolidated Financial Statements” in the Form 10-K for the year ended Dec. 31, 2003.


  For the six months ended June 30, 2004, no income or loss was recognized in connection with hedge ineffectiveness in accordance with SFAS 133, “Accounting for Derivative Instruments and Hedging Activities” (SFAS 133). In the first quarter of 2004, Alliant Energy reclassified a loss of $0.1 million into earnings as a result of the discontinuance of hedges. At June 30, 2004, the maximum length of time over which Alliant Energy hedged its exposure to the variability in future cash flows for forecasted transactions was two months. Alliant Energy estimates that income of $0.5 million will be reclassified from accumulated other comprehensive loss into earnings within the 12 months between July 1, 2004 and June 30, 2005 as the hedged transactions affect earnings.

  As a result of Alliant Energy incurring a loss from continuing operations for the three months ended June 30, 2004, 401,834 potential incremental common shares were excluded from the calculation of diluted EPS for that period because the effect would have been anti-dilutive. In addition, the following options to purchase shares of common stock were excluded from the calculation of diluted EPS as the exercise prices were greater than the average market price for the three and six months ended June 30 as follows:

Alliant Energy completed the sale of its Australian, affordable housing and SmartEnergy, Inc. businesses in the second, third and third quarters of 2003, respectively. In the fourth quarter of 2003, Alliant Energy completed an initial public offering of WPC, leaving Alliant Energy with an approximate 6% ownership interest in WPC that is accounted for under the cost method as of June 30, 2004. As a result of additional common stock issued by WPC in 2004, Alliant Energy currently holds approximately 5% of the common shares of WPC. The operating results for these non-regulated businesses for the three and six months ended June 30, 2003 have been separately classified and reported as discontinued operations in Alliant Energy’s Condensed Consolidated Financial Statements.


  A summary of the components of discontinued operations in Alliant Energy’s Condensed Consolidated Statements of Income for the three and six months ended June 30, 2003 was as follows (in thousands):

In 2004, Alliant Energy adopted revised FIN 46 guidance (FIN 46R). The entities that Alliant Energy consolidated as a result of this guidance did not have a material impact on its financial condition or results of operations. After making an ongoing exhaustive effort, Alliant Energy concluded that for the Riverside and RockGen power plants, it is unable to obtain the information necessary from the counterparties to these tolling and purchased-power agreements, respectively, to determine whether the counterparties are variable interest entities and if Alliant Energy is the primary beneficiary. The counterparties sell some or all of their generating capacity to WP&L, and can sell their energy output to both WP&L and IP&L. The Riverside plant was placed in service in June 2004. In the second quarter of 2004, WP&L and IP&L incurred costs (excluding fuel costs) related to the Riverside contract of $7.2 million and $0.1 million, respectively. WP&L incurred costs related to the RockGen contract of approximately $6.0 million and $23.3 million for the three and six months ended June 30, 2004, and $4.4 million and $16.7 million for the three and six months ended June 30, 2003, respectively. Alliant Energy's maximum exposure to loss from these contracts is undeterminable due to the inability to obtain the necessary information to complete such evaluation.

  Alliant Energy estimates that funding for the pension and postretirement benefit plans for 2004 will be approximately $60 million and $17 million, of which $3 million and $7 million, respectively, have been contributed through June 30, 2004.

  In the second quarter of 2004, Alliant Energy adopted FASB Staff Position (FSP) No. FAS 106-2, “Accounting and Disclosure Requirements Related to the Medicare Prescription Drug, Improvement and Modernization Act of 2003,” (FSP 106-2). Alliant Energy has determined that a substantial portion of the postretirement medical plans are actuarially equivalent to the Medicare Prescription Drug Plan. Alliant Energy anticipates continuing its current prescription drug coverage for currently covered retirees and therefore should be eligible for the subsidy available from Medicare. The estimated reductions in Alliant Energy’s 2004 other postretirement benefits costs and accumulated projected benefit obligation are $3 million and $17 million, respectively.

In March 2004, WP&L discontinued its participation in Alliant Energy’s combined utility customer accounts receivable sale program. WP&L had no receivables sold and no short-term debt outstanding at the time it discontinued its participation in the program. In May 2004, Alliant Energy reduced the maximum amount of receivables that can be sold in the program from $250 million to $175 million, all of which may be sold by IP&L. At June 30, 2004 and Dec. 31, 2003, Alliant Energy had sold $101 million (all at IP&L) and $176 million ($126 million at IP&L and $50 million at WP&L) of domestic utility customer accounts receivable, respectively.

WP&L has signed a definitive agreement to sell its 41% ownership interest in Kewaunee to a subsidiary of Dominion Resources, Inc. (Dominion). Pending various regulatory approvals, including the PSCW, the transaction is expected to be completed in 2004. Approval has already been obtained from the Federal Trade Commission, Nuclear Regulatory Commission, IUB, Illinois Commerce Commission and MPUC, and certain approvals have been obtained from the Federal Energy Regulatory Commission.


  WP&L anticipates that it will receive approximately $90 million in cash and retain ownership of the trust assets contained in one of the two decommissioning funds it has established to cover the eventual decommissioning of Kewaunee. The fund that will be retained had an after-tax value of $69 million on June 30, 2004. Dominion will assume responsibility for the eventual decommissioning of Kewaunee and will receive WP&L’s qualified decommissioning trust assets which had an after-tax value of $173 million on June 30, 2004. The gross cash proceeds from the sale are expected to slightly exceed WP&L’s carrying value of the assets being sold. WP&L has requested deferral of any gain and related costs from the PSCW. Because any gain realized and the retained decommissioning fund will likely be returned to customers in future rate filings, WP&L does not expect this transaction will have a significant impact on its operating results. As of June 30, 2004, WP&L’s share of the carrying value of the assets and liabilities included within the sale agreement was as follows (amounts in millions):

Assets:      Liabilities: 
Investments $173      Asset retirement obligations $193 
Property, plant and equipment, net 78      Regulatory liabilities (4)
Other 13  
 
 
  Total assets $264        Total liabilities $189 
 
 

10

  The assets and liabilities in the previous table do not meet the criteria to be classified as held for sale on the Condensed Consolidated Balance Sheets under the provisions of SFAS 144, “Accounting for the Impairment or Disposal of Long-Lived Assets.” At the closing of the sale, WP&L will enter into a long-term purchased-power agreement with Dominion to purchase energy and capacity equivalent to the amounts received had current ownership continued. The purchased-power agreement, which also will require regulatory approval, will extend through 2013 when Kewaunee’s current operating license will expire. In April 2004, WP&L entered into an exclusivity agreement with Dominion. Under this agreement, if Dominion decides to extend the operating license of Kewaunee, Dominion must negotiate only with WP&L and Wisconsin Public Service Corporation (WPSC) for new purchased-power agreements for their respective share of the plant output that would extend beyond Kewaunee’s current operating license termination date. The exclusivity period will start on the closing date of the sale and will extend through Dec. 21, 2011.

In the second quarter of 2004, Alliant Energy recorded a SFAS 142, “Goodwill and Other Intangible Assets” (SFAS 142), pre-tax non-cash goodwill impairment charge of $43 million related to two of its Integrated Services businesses, primarily due to less favorable market conditions. The fair value of the goodwill was estimated using a combination of the expected discounted future cash flows and market value indicators. The impairment charge was recorded in “Goodwill impairment charge” in continuing operations in Alliant Energy’s Condensed Consolidated Statements of Income for the three and six months ended June 30, 2004. In July 2004, Alliant Energy announced its intent to divest these two businesses and one other business within its Integrated Services business platform. These businesses did not qualify as assets held for sale as of June 30, 2004, however, Alliant Energy expects these businesses will be reported as assets held for sale and discontinued operations in the third or fourth quarter of 2004.

INTERSTATE POWER AND LIGHT COMPANY
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

  Except as modified below, the Alliant Energy Notes to Condensed Consolidated Financial Statements are incorporated by reference insofar as they relate to IP&L.

1.

The interim condensed consolidated financial statements included herein have been prepared by IP&L, without audit, pursuant to the rules and regulations of the SEC. Accordingly, certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted, although management believes that the disclosures are adequate to make the information presented not misleading. The condensed consolidated financial statements include IP&L and its consolidated subsidiaries. IP&L is a direct subsidiary of Alliant Energy. These financial statements should be read in conjunction with the financial statements and the notes thereto included in IP&L’s latest Annual Report on Form 10-K.


  In the opinion of management, all adjustments, which are normal and recurring in nature, necessary for a fair presentation of (a) the condensed consolidated results of operations for the three and six months ended June 30, 2004 and 2003 (b) the condensed consolidated financial position at June 30, 2004 and Dec. 31, 2003, and (c) the condensed consolidated statements of cash flows for the six months ended June 30, 2004 and 2003 have been made. Because of the seasonal nature of IP&L’s operations, results for the three and six months ended June 30, 2004 are not necessarily indicative of results that may be expected for the year ending Dec. 31, 2004. Certain prior period amounts have been reclassified on a basis consistent with the current period presentation.

2.

For the three and six months ended June 30, 2004 and 2003, IP&L had no other comprehensive income, thus IP&L’s comprehensive income was equal to its earnings available for common stock for all periods.


3.

Certain financial information relating to IP&L’s significant business segments is as follows. Intersegment revenues were not material to IP&L’s operations.

  The pension benefits costs shown in the previous table represent only the pension benefits costs for bargaining unit employees of IP&L covered under the bargaining unit pension plans that are sponsored by IP&L. The pension benefits costs for IP&L’s non-bargaining employees who are participants in other Alliant Energy plans were $0.8 million and $1.1 million for the three months ended June 30, 2004 and 2003, and $1.5 million and $2.2 million for the six months ended June 30, 2004 and 2003, respectively. In addition, Corporate Services provides services to IP&L. The allocated pension benefits costs associated with these services were $0.8 million and $0.7 million for the three months ended June 30, 2004 and 2003, and $1.7 million and $1.5 million for the six months ended June 30, 2004 and 2003, respectively. The other postretirement benefits costs shown previously represent the allocated other postretirement benefits costs for all IP&L plans. The allocated other postretirement benefits costs associated with Corporate Services for IP&L were $0.6 million and $0.4 million for the three months ended June 30, 2004 and 2003, and $1.2 million and $0.8 million for the six months ended June 30, 2004 and 2003, respectively.

  IP&L estimates that funding for the qualified pension and postretirement benefit plans for 2004 will be approximately $19 million and $12 million, of which $3 million and $6 million, respectively, have been contributed through June 30, 2004.

  As a result of the adoption of FSP 106-2 in the second quarter of 2004 and anticipated eligibility for subsidies from Medicare, the estimated reductions in IP&L’s 2004 other postretirement benefits costs and accumulated projected benefit obligation are $1 million and $9 million, respectively.

  The pension benefits costs shown in the previous table represent only the pension benefits costs for bargaining unit employees of WP&L covered under the bargaining unit pension plan that is sponsored by WP&L. The pension benefits costs for WP&L’s non-bargaining employees who are participants in other Alliant Energy plans were $0.2 million and $0.4 million for the three months ended June 30, 2004 and 2003, and $0.3 million and $0.9 million for the six months ended June 30, 2004 and 2003, respectively. In addition, Corporate Services provides services to WP&L. The allocated pension benefits costs associated with these services were $0.6 million and $0.5 million for the three months ended June 30, 2004 and 2003, and $1.1 million and $1.0 million for the six months ended June 30, 2004 and 2003, respectively. The other postretirement benefits costs shown previously represent the allocated other postretirement benefits costs for all WP&L plans. The allocated other postretirement benefits costs associated with Corporate Services for WP&L were $0.4 million and $0.2 million for the three months ended June 30, 2004 and 2003, and $0.8 million and $0.5 million for the six months ended June 30, 2004 and 2003, respectively.

  WP&L estimates that funding for the qualified pension and postretirement benefit plans for 2004 will be approximately $0 and $4 million, respectively, of which $2 million has been contributed to the postretirement benefit plans as of June 30, 2004.

  As a result of the adoption of FSP 106-2 in the second quarter of 2004 and anticipated eligibility for subsidies from Medicare, the estimated reductions in WP&L’s 2004 other postretirement benefits costs and accumulated projected benefit obligation are $1 million and $7 million, respectively.

STRATEGIC OVERVIEW

Alliant Energy’s domestic utility business is its core business and the sole growth platform within its strategic plan. The strategic plan is concentrated on building and maintaining the generation and infrastructure necessary to provide Alliant Energy’s domestic utility customers with safe, reliable and environmentally sound energy service. Alliant Energy’s strategic plan also includes focusing on the profitability and cash flows of its remaining non-regulated businesses which will serve as ongoing business platforms. The following is an update related to recent activities of Alliant Energy’s domestic utility generation plan:

o   IP&L’s 565 MW, combined-cycle, natural gas-fired generating facility (Emery) near Mason City, Iowa was completed on time and on budget and placed in service in May 2004.
o   Calpine Corporation’s 600 MW, combined-cycle, natural gas-fired generating facility (Riverside) in Beloit, Wisconsin was placed in service in June 2004. WP&L has contracted for 453 MW of this plant’s output.

29

o   Alliant Energy continues to make steady progress related to acquiring regulatory approvals for the 300 MW, simple-cycle, natural gas-fired generating facility to be constructed near Sheboygan Falls, Wisconsin. Resources’ Non-regulated Generation business began construction of the generating facility in early August 2004 and is expected to complete the facility in time to meet increased summer demand in 2005. Alliant Energy is proposing that Resources’ Non-regulated Generation business would own the facility and enter into a long-term agreement with WP&L whereby WP&L would operate and maintain the facility as well as purchase the power generated by the facility. The facility is expected to cost approximately $155 million, of which $80 million had already been expended as of June 30, 2004. The proposed structure is still subject to final PSCW approval.
o   WP&L is reviewing the bids it received earlier this year for adding 100 MW of wind generation in one or more locations in Wisconsin in 2005. Moving forward with this component of the generation plan is contingent upon a renewal of the federal renewable energy production tax credit.
o   In May 2004, Alliant Energy announced WP&L would pursue plans to build a jointly-owned 500 MW base-load electric plant with WPSC (respective ownership levels have not yet been determined). The planning process will include feasibility and siting studies. Based on the current energy requirement studies of both companies, WP&L expects significant increases in electric supply are likely to be needed to offset rising energy demand by 2010.

Alliant Energy also continues to evaluate the performance of all its businesses, both utility and non-regulated, and is focused on taking actions to increase the returns earned on invested capital in all of its businesses. Alliant Energy is committed to streamlining its portfolio of businesses to only those that can provide meaningful earnings and cash flows for shareowners and those it is prepared to invest the capital needed to reach the scale necessary to generate such earnings and cash flows. Consistent with this strategic focus, Alliant Energy announced in July 2004 its intent to divest the following businesses within its Integrated Services business platform:

o   Cogenex Corporation, an energy services business, based in Lowell, Mass., and affiliated companies;
o   NG Energy Trading, LLC (NGE), a gas marketing business, based in Oklahoma City, Okla.; and
o   Energy management services business, which includes offices in Florida, Minnesota and Wisconsin.

Alliant Energy is in the early stages of developing its divestiture plan for these businesses and intends to complete the divestitures within a year and expects the results of these businesses will qualify for reporting as assets held for sale and discontinued operations in the third or fourth quarter of 2004. Alliant Energy intends to apply any proceeds from the divestiture of these businesses toward debt reduction at Resources. The net income (loss) from these businesses included in Alliant Energy’s consolidated income (loss) from continuing operations were ($46.1) million and ($0.9) million for the three months ended June 30, 2004 and 2003, and ($48.3) million and $1.3 million for the six months ended June 30, 2004 and 2003, respectively. Both the three and six months ended June 30, 2004 included ($40.3) million of SFAS 142 after-tax non-cash goodwill impairment charges. Refer to Note 13 of Alliant Energy’s “Notes to Condensed Consolidated Financial Statements” for additional information regarding the goodwill impairment charges.

RATES AND REGULATORY MATTERS

A summary of the regulatory environment is included in the combined Form 10-K filed by Alliant Energy, IP&L and WP&L for the year ended Dec. 31, 2003. Set forth below are recent developments relating to the regulatory environment.

Details of Alliant Energy’s rate cases impacting its historical and future results of operations are as follows (dollars in millions):

(1)  

Interim rate relief is implemented, subject to refund, pending determination of final rates. The final rate relief granted replaces the amount of interim rate relief granted.

(2)  

Since the final increase was lower than the interim relief granted, a refund to customers was made in 2003.

(3)  

The regulatory process in Wisconsin enables WP&L to adjust its request, either up or down, in response to fuel cost changes since the interim order. WP&L has experienced modest increases in its fuel and purchased-power costs since the interim order was issued. WP&L continues to monitor these costs and will update the record in the rate proceeding as allowed.

(4)  

IP&L requested interim rate relief of approximately $106 million. In July 2004, a non-unanimous settlement agreement was filed with the IUB proposing resolution of all revenue requirement issues in the case. A majority of the parties to the case signed the settlement agreement including IP&L, the Iowa Office of Consumer Advocate, and certain other customers and/or customer groups. The parties agreed to an increase in IP&L’s annual Iowa electric rates of $107 million ($9 million more than the revenues granted in the IUB’s interim order) and a return on equity for capital unrelated to Emery of 10.7%. Capital related to Emery will continue to earn a return on equity of 12.23% consistent with the ratemaking principles granted by the IUB in 2002. The elements in the settlement agreement are subject to approval by the IUB. A decision by the IUB on the settlement is expected in the first quarter of 2005. The filing of the settlement agreement does not impact interim rates.

With the exception of recovering a return on IP&L’s Emery plant, which is a large component of IP&L’s retail Iowa electric rate case filed in March 2004, a significant portion of the rate increases included in the previous table reflect the recovery of increased costs incurred by IP&L and WP&L, or costs they expect to incur. Thus, the increase in revenues related to these rate increases have not resulted or are not expected to result in a corresponding increase in net income.

In March 2004, a new ratemaking law was enacted in Iowa. The new law allows utilities to place in effect interim rates, subject to refund, without review by the IUB within ten days of filing a general rate increase request. The law also allows the IUB to consider known and measurable changes in costs and revenues occurring within nine months from the end of the historical test year in setting final rates in a rate case. Both of these changes are designed to mitigate regulatory lag in Iowa ratemaking, which uses a historical versus projected test year in setting rates. IP&L does not expect this new law to have any impact on its pending retail electric rate case in Iowa as it is only expected to impact future Iowa rate cases.

ALLIANT ENERGY RESULTS OF OPERATIONS

Unless otherwise noted, all “per share” references in the Results of Operations section refer to earnings perdiluted share.

Overview — Second Quarter Results Alliant Energy’s net income (loss) and EPS for the second quarter were as follows (dollars in millions; totals may not foot due to rounding):

 2004* 2003*
 
Continuing operations: Net Income   EPS   Net Income EPS 
 
    Domestic utility $38 .9 $0 .42 $22.6$0.24

Income from discontinued operations --   --   20.40.22
 
Net income (loss) ($13 .1) ($0 .12) $32.2$0.35
 
     *  The 2004 and 2003 EPS amounts have been computed based on the average diluted shares outstanding in 2003. For purposes of this table, Alliant Energy reports the impact of increased shares outstanding as a separate earnings variance item if it is material.

The increase in domestic utility income from continuing operations was primarily due to higher electric and gas margins. The decline in Alliant Energy’s non-regulated results from continuing operations was primarily due to a SFAS 142 after-tax non-cash goodwill impairment charge of $40 million in the second quarter of 2004 and lower results from its International and Integrated Services business units, partially offset by an $8 million reduction in interest expense resulting from Alliant Energy’s continuing debt reduction program.

Electric margins increased $22.3 million, or 8%, and $45.4 million, or 9%, for the three- and six-month periods, respectively, primarily due to the impact of various rate increases implemented in 2003 and 2004 and an increase in retail sales resulting from continued customer and other sales growth of 3% and 2%, respectively. The six-month increase was also due to the impact on the comparison of a significant under-recovery of purchased-power and fuel costs at WP&L in the first quarter of 2003, partially offset by the impact of seasonal rates at WP&L, implemented for the first time in April 2003. Electric margins in 2004 were also negatively impacted by higher than anticipated purchased-power and fuel costs at WP&L. WP&L filed a fuel-only rate case in the first quarter of 2004 and an interim rate increase of approximately $16 million was implemented in late March 2004. Weather had a modest downward impact on electric margins for the three- and six-month periods in 2004 and 2003.

In April 2003, WP&L implemented seasonal electric rates that are designed to result in higher rates for the peak demand period from June 1 through Sept. 30 and lower rates in all other periods during each calendar year. As a result, total annual revenues are not expected to be impacted significantly. However, the margins for the six-months ended June 30, 2004, were approximately $7 million lower than the same period in 2003, all other things being equal, given the seasonal rates were not yet effective in the first quarter of 2003.

Gas margins increased $3.9 million, or 15%, and decreased $1.5 million, or 2%, for the three- and six-month periods, respectively. The three-month increase was primarily due to a $2 million rate refund reserve recorded in the second quarter of 2003 at IP&L and improved results of $1 million from WP&L’s performance-based commodity cost recovery program (benefits are shared by ratepayers and shareowners). The six-month decrease was primarily due to lower sales, which were partially due to milder weather conditions in the first quarter of 2004 compared with the same period in 2003, primarily offset by improved results of $3 million from WP&L’s performance-based commodity cost recovery program.

Refer to “Rates and Regulatory Matters” for discussion of various electric and gas rate filings.

Domestic Utility Other RevenuesOther revenues for the domestic utilities decreased $5.1 million and $9.1 million for the three- and six-month periods, respectively, due to lower construction management revenues from WindConnect™ due to the current uncertainty regarding extension of the federal renewable energy production tax credit. The decrease was largely offset by lower other operation and maintenance expenses related to the WindConnect™ program.

The decreased Integrated Services revenues for the three- and six-month periods were primarily due to decreased gas revenues at Alliant Energy’s natural gas marketing business, NGE, including reduced sales opportunities as a result of less volatility in gas prices and higher sales to electric generating facilities used during peak demand in the second quarter of 2003. The increased International revenues for the three- and six-month periods were primarily due to the acquisition of an additional combined heat and power facility in China in the second quarter of 2003 and increased production at its generating facilities in China.

Other Operating ExpensesOther operation and maintenance expense for the domestic utilities decreased $15.8 million and $8.6 million for the three- and six-month periods, respectively, primarily due to the impact at WP&L of a planned refueling outage at Kewaunee in the second quarter of 2003 (there was no such outage in 2004), lower expenses for WindConnect™ and decreases in transmission and distribution costs. These items were partially offset by increases in employee and retiree benefits (comprised of compensation, medical and pension costs).

Non-regulated operation and maintenance expenses for the three and six months ended June 30 were as follows (in thousands):

The Integrated Services and International variances for the three- and six-month periods were largely driven by the same factors impacting the revenue variances discussed previously. The International increase for the three- and six-month periods was also impacted by higher coal and related costs for its generating facilities in China. Refer to “Other Matters — Other Future Considerations — China” for additional discussion.

The goodwill impairment charge in the second quarter of 2004 was a SFAS 142 pre-tax non-cash charge Alliant Energy recorded to write-off $43 million of the $44 million of goodwill on the balance sheets of the Integrated Services businesses Alliant Energy intends to divest. Refer to Note 13 of Alliant Energy’s “Notes to Condensed Consolidated Financial Statements” for further details. Depreciation and amortization expense increased $6.8 million and $12.2 million for the three- and six-month periods, respectively, primarily due to utility property additions, including the Emery plant. Taxes other than income taxes increased $4.9 million and $5.1 million for the three- and six-month periods, respectively, primarily due to increased gross receipts and property taxes.

Interest Expense and OtherInterest expense decreased $11.2 million and $22.2 million for the three- and six-month periods, respectively, primarily due to lower average borrowings as a result of debt retirements within Alliant Energy’s non-regulated businesses in 2003 and 2004, and credit facility fees incurred at Resources in 2003. The impact of additional equity issued during the last 12 months and various debt refinancings also contributed to the decrease.

Loss on early extinguishment of debt in the first quarter of 2004 includes debt repayment premiums and charges for the unamortized debt expenses related to long-term debt retirements of $20 million of senior notes at Resources.

Equity (income) loss from Alliant Energy’s unconsolidated investments for the three and six months ended June 30 was as follows (in thousands):

The lower equity income from Alliant Enegy’s Brazil investments for the three-month period was primarily due to the impact of foreign currency transaction gains (losses) of ($1.0) million and $2.5 million recorded in the second quarters of 2004 and 2003, respectively, and higher operating, litigation-related and interest expenses at the Brazilian operating companies. These items were partially offset by the impact of rate increases implemented at the Brazilian operating companies. The higher equity income from the Brazil investments for the six-month period was primarily due to rate increases implemented at the Brazilian operating companies and a gain of $5.1 million (representing Alliant Energy’s allocated portion of the total gain) realized in the first quarter of 2004 from the sale of two hydroelectric plants, partially offset by the reasons described previously for the three-month decrease. The increased equity income from New Zealand for the six-month period was primarily due to higher electric margins resulting from higher energy prices.

Allowance for funds used during construction (AFUDC) increased $1.2 million and $4.4 million for the three- and six-month periods, respectively, primarily due to construction of the Emery plant.

Interest income and other decreased $6.8 million and $11.4 million for the three- and six-month periods, respectively, largely due to lower foreign currency transaction gains/losses, lower non-cash valuation adjustments related to Alliant Energy’s McLeod trading securities, gains from sales of modest investments in New Zealand in the second quarter of 2003 and lower interest income. The lower interest income for the six-month period was primarily due to the elimination of loans to discontinued operations due to asset sales during 2003. Refer to Note 14 of Alliant Energy’s “Notes to Condensed Consolidated Financial Statements” for further details.

Income TaxesThe effective income tax rates were 47.1% for the six-month period ended June 30, 2004, compared with 28.4% and 29.4% for the three- and six-month periods, respectively, ended June 30, 2003. The effective tax rate for the three-month period ended June 30, 2004 is not meaningful given the insignificant amount of pre-tax loss from continuing operations in such period. The 2004 three- and six-month income taxes were negatively impacted by the tax treatment related to the goodwill impairment charge recorded in the second quarter. Refer to Note 4 of Alliant Energy’s “Notes to Condensed Consolidated Financial Statements” for further details.

35

Loss from Discontinued Operations Refer to Note 7 of Alliant Energy’s “Notes to Condensed Consolidated Financial Statements” for discussion of Alliant Energy’s discontinued operations.

Cumulative Effect of Changes in Accounting Principles In the first quarter of 2003, Alliant Energy recorded after-tax charges of $4 million and $2 million for the cumulative effect of changes in accounting principles related to the adoption on Jan. 1, 2003 of SFAS 143 and Emerging Issues Task Force Issue 02-3, “Issues Related to Accounting for Contracts Involved in Energy Trading and Risk Management Activities” within WPC and Integrated Services, respectively.

IP&L RESULTS OF OPERATIONS

Overview — Second Quarter Results Earnings available for common stock increased $3.9 million, primarily due to higher electric margins partially offset by increased other operating expenses.

Electric margins increased $15.7 million, or 11%, and $14.6 million, or 5%, for the three- and six-month periods, respectively, primarily due to the impact of various rate increases implemented in 2003 and 2004, including increased revenues to recover a significant portion of IP&L’s increased operating expenses, increased retail sales resulting from continued customer and other sales growth and lower purchased-power capacity costs. Weather had a modest downward impact on electric margins for the three- and six-month periods in 2004 and 2003.

Gas margin increased $1.3 million, or 10%, and decreased $3.2 million, or 7%, for the three- and six-month periods, respectively. The three-month increase was primarily due to a $2 million rate refund reserve recorded in the second quarter of 2003. The six-month decrease was primarily due to lower sales, which were partially due to slightly milder weather in the first quarter of 2004 compared to the same period in 2003.

Refer to “Rates and Regulatory Matters” for discussion of IP&L’s electric and gas rate filings.

Steam and Other Revenues Steam and other revenues decreased $2.6 million for the six-month period primarily due to lower construction management revenues from WindConnect™, due to the current uncertainty regarding extension of the federal renewable energy production tax credit. The decrease was largely offset by lower other operation and maintenance expenses related to IP&L’s WindConnect™ program.

Other Operating Expenses Other operation and maintenance expenses increased $1.4 million and $4.9 million for the three- and six-month periods, respectively, primarily due to increases in employee and retiree benefits (comprised of compensation, medical and pension costs), partially offset by lower transmission and distribution costs. The six-month increase was also partially offset by lower expenses for WindConnect™. Depreciation and amortization expense increased $6.5 million and $13.3 million for the three- and six-month periods, respectively, primarily due to property additions, including the Emery plant.

Interest Expense and Other AFUDC increased $1.1 million and $4.8 million for the three- and six-month periods, respectively, due to construction of the Emery plant.

Income Taxes The effective income tax rates were 43.5% and 42.3% for the three- and six-month periods ended June 30, 2004, respectively, compared with 40.8% and 39.6% for the same periods last year. The increases for the three- and six-month periods were primarily due to increases in property-related temporary differences for which deferred tax expense is not recorded pursuant to rate making principles. The six-month increase was also due to a decrease in the Alliant Energy tax benefit allocated to IP&L pursuant to the provisions of PUHCA.

WP&L RESULTS OF OPERATIONS

Overview — Second Quarter Results Earnings available for common stock increased $11.3 million, primarily due to lower other operating expenses and higher electric and gas margins.

Electric margins increased $6.6 million, or 5%, and $30.8 million, or 14%, for the three- and six-month periods, respectively, primarily due to the implementation of rate increases in 2003 and 2004 and increased retail sales resulting from continued customer and other sales growth. The six-month increase was also due to the impact on the comparison of a significant under-recovery of purchased-power and fuel costs in the first quarter of 2003, partially offset by the impact of implementing seasonal rates in 2003. Electric margins in 2004 were also negatively impacted by higher than anticipated fuel and purchased-power costs. WP&L filed a fuel-only rate case in the first quarter of 2004 and an interim rate increase of approximately $16 million was implemented in late March 2004. Weather had a modest downward impact on electric margins for the three- and six-month periods in 2004 and 2003. Refer to “Alliant Energy Results of Operations” for further discussion of seasonal electric rates.

Gas margins increased $2.6 million, or 20%, and $1.7 million, or 4%, for the three- and six-month periods, respectively, primarily due to improved results of $1 million and $3 million, respectively, from WP&L’s performance-based commodity cost recovery program (benefits are shared by ratepayers and shareowners). The six-month increase was partially offset by lower sales, due to milder weather conditions in the first quarter of 2004 compared with the same period in 2003.

Refer to “Rates and Regulatory Matters” for discussion of WP&L’s electric and gas rate filings.

Other RevenuesOther revenues decreased $6.0 million and $6.4 million for the three- and six-month periods, respectively, primarily due to lower construction management revenues from WindConnect™ due to the current uncertainty regarding extension of the federal renewable energy production tax credit. The decrease was largely offset by lower other operation and maintenance expenses related to WP&L’s WindConnect™ program.

Other Operating Expenses Other operation and maintenance expenses decreased $15.4 million and $11.8 million for the three- and six-month periods, respectively, primarily due to the impact of a planned refueling outage at Kewaunee in the second quarter of 2003 (there was no such outage in 2004), lower expenses for WindConnect™ and decreases in the amortization of deferred costs recovered in rates. These items were partially offset by increases in employee and retiree benefits (comprised of compensation, medical and pension costs). Taxes other than income taxes increased $2.5 million and $3.1 million for the three- and six-month periods, respectively, primarily due to increased gross receipts taxes.

Interest Expense and Other Interest expense decreased $2.5 million and $3.8 million for the three- and six-month periods, respectively, primarily due to lower average borrowings.

Income TaxesThe effective income tax rates were 38.6% and 38.4% for the three- and six-month periods ended June 30, 2004, respectively, compared with 37.9% and 34.7%, respectively, for the same periods last year. The increase for the six-month period was primarily due to a decrease in the Alliant Energy tax benefit allocated to WP&L pursuant to the provisions of PUHCA.

LIQUIDITY AND CAPITAL RESOURCES

Cash Flows for the Six-Month PeriodsSelected information from Alliant Energy’s, IP&L’s and WP&L’s respective Condensed Consolidated Statements of Cash Flows for the six months ended June 30 was as follows (in thousands):

   Investing activities (304,610 )(225,699)(196,180 )(296,921)(82,886 )(70,789)

Alliant Energy’s cash flows from operating activities increased $52 million, primarily due to higher net income at WP&L and changes in working capital, including lower gas storage balances and timing of collections and payables, partially offset by changes in the level of accounts receivable sold; cash flows used for financing activities increased $30 million, primarily due to changes in the amount of debt issued and retired, partially offset by proceeds from Alliant Energy’s continuous equity offering program in the second quarter of 2004; and cash flows used for investing activities increased $79 million, primarily due to proceeds received from the sale of Alliant Energy’s Australian business in April 2003, partially offset by the 2003 acquisition by Resources of a 309 MW, non-regulated, tolled, natural gas-fired power plant in Neenah, Wisconsin, and other decreases in non-regulated construction and acquisition expenditures. IP&L’s cash flows used for financing activities increased $100 million, primarily due to changes in the amount of debt issued and retired, partially offset by capital contributions of $50 million from Alliant Energy; and cash flows used for investing activities decreased $101 million, primarily due to lower construction and acquisition expenditures associated with the construction of the Emery plant. WP&L’s cash flows from operating activities increased $14 million, primarily due to higher net income and changes in working capital; cash flows used for financing activities increased $20 million due to higher common stock dividends and net changes in the amount of debt issued and retired; and cash flows used for investing activities increased $12 million, primarily due to increased levels of construction expenditures.

Certain Regulatory Approvals/Requirements PUHCA Alliant Energy is subject to a PUHCA requirement whereby Alliant Energy’s common equity balance must be at least 30% of its total consolidated capitalization, including short-term debt. Alliant Energy’s common equity ratio as of June 30, 2004, as computed under this requirement, was 46.9%.

State Regulatory Agencies — In March 2004, IP&L received the necessary regulatory authorization to increase short-term borrowings from $250 million to $300 million. In March 2004, WP&L discontinued its utility customer accounts receivable sale program, increasing its short-term borrowing authority granted by the PSCW to $185 million for general corporate purposes and an additional $55 million should WP&L need to repurchase its variable rate demand bonds.

Shelf Registrations In 2004, Alliant Energy, IP&L and WP&L each filed separate shelf registrations with the SEC. Alliant Energy’s shelf registration became effective in April 2004 and allows Alliant Energy flexibility to offer from time to time up to an aggregate of $300 million of common stock, stock purchase contracts and stock purchase units. IP&L’s shelf registration became effective in April 2004 and allows IP&L flexibility to offer from time to time up to an aggregate of $210 million of preferred stock, senior unsecured debt securities and collateral trust bonds. WP&L’s shelf registration became effective in April 2004 and allows WP&L flexibility to offer from time to time up to an aggregate of $150 million of its preferred stock, senior unsecured debt securities and first mortgage bonds. Alliant Energy, IP&L and WP&L had $254 million, $85 million and $50 million remaining available under their respective shelf registrations at August 5, 2004.

Cash and Temporary Cash Investments As of June 30, 2004, Alliant Energy and its subsidiaries had approximately $189 million of cash and temporary cash investments, of which approximately $73 million consisted of deposits in foreign bank accounts. Due to Alliant Energy electing permanent reinvestment of earnings for federal income tax purposes for certain foreign subsidiaries within its China business platform, a majority of the cash held in foreign banks cannot be repatriated without material tax obligations. Alliant Energy plans to use a portion of this cash held in foreign bank accounts to invest in future capital projects in China.

Sale of Accounts Receivable Refer to Note 11 of Alliant Energy’s “Notes to Condensed Consolidated Financial Statements” for information on WP&L’s discontinuance of participation in the utility customer accounts receivable sale program and a reduction in the maximum amount of receivables that can be sold in the program.

In July 2004, Alliant Energy completed the syndication of three revolving credit facilities totaling $650 million ($100 million for Alliant Energy at the parent company level, $300 million for IP&L and $250 million for WP&L), which support commercial paper and are available for direct borrowings. The combined total amount of the new facilities remains the same as the former facilities, however, $100 million of the borrowing capability has been shifted from the parent company to IP&L and WP&L to support the continued focus on the domestic utility business as the primary source of future capital needs. The facility at the parent company is used to fund Resources and Corporate Services as well as its own needs. These new facilities replaced the former facilities which were to expire in September 2004. These new facilities are designed to be five-year facilities with the length of the facilities still being subject to various state and federal regulatory approvals given the term is longer than a 364-day facility. With the exception of the consolidated net worth covenant, which has been removed, the new credit facility agreements contain similar covenants as the former credit facility agreements, including the following:

Alliant Energy:  
   Consolidated debt-to-capital ratioLess than 65%48.4%
   EBITDA interest coverage ratio (*)At least 2.5x4.0x 
IP&L debt-to-capital ratioLess than 58%47.2%
WP&L debt-to-capital ratioLess than 58%30.2%
(*)In compliance with the agreement, results of discontinued operations have been included in this covenant calculation.

The cross default provisions, negative pledge provisions and material adverse change clauses of the new credit facilities are less restrictive than those of the former credit facilities. Alliant Energy’s, IP&L’s and WP&L’s new credit facilities contain provisions that require, during the term of the facilities, any proceeds from asset sales, with certain exclusions, in excess of 20% of their respective consolidated assets be used to reduce commitments under their respective facilities. Exclusions include, among others, certain sale and lease-back transactions and any potential sales of Alliant Energy’s nuclear, transmission or international assets.

Long-term Debt In August 2004, WP&L issued $100 million of 6.25% senior debentures due 2034 and used the proceeds to repay short-term debt, including $62 million incurred in connection with the repayment at maturity of 7.25% first mortgage bonds in June 2004, and for general corporate purposes. IP&L issued $25 million and $100 million of 6.30% senior debentures due 2034 in August 2004 and May 2004, respectively, and used the proceeds to repay short-term debt primarily incurred in the construction of the Emery plant and for general corporate purposes. All of these long-term debt issuances were executed in connection with WP&L’s and IP&L’s respective shelf registrations discussed previously. In February 2004, Resources retired $10.0 million of its 9.75% senior notes and $9.5 million of its 7% senior notes, incurring approximately $0.03 per share of debt repayment premiums.

Common Equity In connection with Alliant Energy's 2004 shelf registration discussed previously, it is Alliant Energy's current intent to issue up to $150 million of new common stock during 2004. Alliant Energy has entered into a sales agreement with Cantor Fitzgerald & Co., under which Alliant Energy may sell from time to time up to 7.5 million shares of its common stock. During the second quarter of 2004, Alliant Energy issued approximately 1.6 million shares of new common stock and received approximately $37 million in net proceeds under this shelf registration and sales agreement. In the third quarter of 2004, Alliant Energy has issued approximately 0.3 million additional shares and received approximately $8 million in net proceeds through August 5, 2004 under this shelf registration and sales agreement. Refer to "Shelf Registrations" for additional information.

Credit Ratings In May 2004, Standard & Poor’s Rating Services lowered WP&L’s secured long-term debt rating from A to A- to align it with WP&L’s corporate/issuer credit rating.

The Wisconsin Department of Natural Resources (DNR) independently developed proposed mercury control rules for Wisconsin generating facilities that will cap emissions beginning in 2008, followed by subsequent reductions of 40% by 2010 and 75% by 2015. These rules have been approved by the Wisconsin legislature and are expected to become effective in the second half of 2004. The Wisconsin mercury rule requirements will be superseded by federal mercury emissions standards when published. Alliant Energy is currently evaluating the expected impact of the Wisconsin rules and also continues to closely monitor the developments at the federal level related to mercury emissions standards.

Refer to “Legal Proceedings” for discussion of complaints filed against WP&L and Alliant Energy regarding the Columbia generating station.

OTHER MATTERS

Market Risk Sensitive Instruments and Positions Alliant Energy’s primary market risk exposures are associated with interest rates, commodity prices, equity prices and currency exchange rates. Alliant Energy has risk management policies to monitor and assist in controlling these market risks and uses derivative instruments to manage some of the exposures. A summary of Alliant Energy’s market risks is included in Alliant Energy’s, IP&L’s and WP&L’s combined Form 10-K for the year ended Dec. 31, 2003 and have not changed materially from those reported in the 2003 Form 10-K, except as described below.

Commodity Risk — Non-trading — Refer to “Other Future Considerations — China” for discussion of higher than anticipated coal and other related costs in China.

Accounting Pronouncements As of March 31, 2004, Alliant Energy adopted FIN 46R guidance. Refer to Note 8 of Alliant Energy’s “Notes to Condensed Consolidated Financial Statements” for additional information.

In December 2003, the President signed into law the Medicare Prescription Drug, Improvement and Modernization Act of 2003 (the Act). The Act introduces a prescription drug benefit under Medicare Part D, as well as a federal subsidy to sponsors of retiree health care benefit plans, that provide a benefit that is at least actuarially equivalent to Medicare Part D. In the second quarter of 2004, the FASB issued, and Alliant Energy elected early adoption of, FSP 106-2, which supersedes FSP 106-1. Refer to Note 10 of Alliant Energy’s, IP&L’s and WP&L’s “Notes to Condensed Consolidated Financial Statements” for additional information.

Critical Accounting Policies A summary of Alliant Energy’s critical accounting policies is included in Alliant Energy’s, IP&L’s and WP&L’s combined Form 10-K for the year ended Dec. 31, 2003 and have not changed materially from those reported in the 2003 10-K. Refer to Note 13 of Alliant Energy’s “Notes to Condensed Consolidated Financial Statements” for information regarding a goodwill impairment charge recorded in the second quarter of 2004.

Other Future Considerations A summary of Alliant Energy’s, IP&L’s and WP&L’s other future considerations is included in the combined Form 10-K filed by Alliant Energy, IP&L and WP&L for the year ended Dec. 31, 2003 and have not changed materially from those reported in the 2003 Form 10-K, except as described below. In addition to items discussed earlier in MD&A, the following items could impact Alliant Energy’s future financial condition or results of operations:

Mexico — At June 30, 2004, Resources held a secured loan receivable of approximately $82 million from an unrelated Mexican development company. The loan proceeds were used by the development company to construct substantially all the infrastructure for the initial phase of a master-planned resort community known as Laguna del Mar located near Puerto Penasco, State of Sonora, on the Sea of Cortez. Alliant Energy has concerns regarding the Mexican development company’s ability to timely complete all phases of the project, market and sell the real estate, and otherwise meet all of its obligations under the loan documents. Negotiations are currently underway between Resources and the owners of the development company to resolve this matter. Resources is evaluating its alternatives, which include possibly restructuring a role for its developers or replacing them, a transfer of ownership and control of the project to Resources or the exercise of Resources’ remedies through legal action. Effective Jan. 1, 2004, Resources ceased accruing interest income related to this loan pending resolution of this matter. If the development of the project and related real estate sales are not ultimately successfully executed, it is possible that Alliant Energy could incur material asset valuation charges in the future. Alliant Energy is unable to predict the ultimate outcome of this matter.

42

Brazil — To complete earlier plans, the Juiz de Fora facility, a joint venture gas-fired generating facility in which Alliant Energy holds a 50% direct ownership interest, is scheduled for a 20 MW expansion from a single cycle to a combined cycle facility at an estimated cost of $24 million. However, initiation of the expansion construction is experiencing some delays due to disputes with Alliant Energy’s Brazilian partner regarding the financing and construction of the Juiz de Fora facility and other matters (as mentioned below). Alliant Energy is currently discussing with its partner resolution of these matters in order to ensure timely completion of the project in early 2006. If the Juiz de Fora combined-cycle construction is not completed as anticipated, the future performance obligations of this generation asset might be significantly adversely affected. In such an event, Alliant Energy is not required to invest any additional capital in Juiz de Fora; however, it could lead to material asset valuation or other charges with respect to Alliant Energy’s investment in the Juiz de Fora facility. Alliant Energy’s direct investment in the Juiz de Fora facility at June 30, 2004 was approximately $15 million.

Alliant Energy continues to closely monitor the financial performance of its Brazilian investments. While such performance improved significantly in 2003, Alliant Energy believes the rate of improvement can be enhanced, particularly in regard to controlling costs and reduction of debt, and this has been a source of dispute with its Brazilian partners. In particular, Alliant Energy’s Brazilian partners want to use company funds to pay dividends in order to ensure their control over the operations. Alliant Energy is not interested in and has not sought control of the operations. However, Alliant Energy has urged that, to the extent funds are available, they would be better used to pay down debt.

Alliant Energy has been and continues to explore with various parties, including its existing Brazilian partners, all of the options available to it concerning its investments in Brazil. Alliant Energy will consider the full range of options potentially available. Consequently, Alliant Energy is unable to provide any assurances that one or more of the options under review will occur, or that implementation of any one or more of the options will not result in Alliant Energy incurring a material charge as relates to its investments in Brazil as it cannot currently predict the ultimate outcome of these reviews and discussions.

China — The generating plants included in Alliant Energy’s China portfolio are currently experiencing higher than anticipated coal and related costs due primarily to government allocations and infrastructure bottlenecks.  Alliant Energy is attempting to mitigate the impact of these cost increases by working with local Chinese authorities to increase the supply of lower-cost coal, working with local Chinese power commissions to enable it to recover the higher costs through tariffs and reviewing for other ways to offset these cost increases within its operations.  However, the process does require government interaction and is less formal and predictable than general fuel-related cost recovery processes within the domestic utility industry. If the price of coal and related costs were to increase (decrease) 10% compared to the average prices experienced during the 12 months ended June 30, 2004, Alliant Energy’s net income for the 12 months ended June 30, 2005 would (decrease) increase by approximately $5 million.

In addition to applying pressure on the margins currently being realized from Alliant Energy’s China operations, these cost pressures could impact the estimated fair value of Alliant Energy’s China investments. Alliant Energy has $10 million of goodwill related to its China investments on its balance sheet and if the fair value of these investments does not exceed their carrying value (including goodwill) in the future, Alliant Energy may be required to record an impairment charge related to this goodwill balance. Alliant Energy is unable to predict the future of these costs in China or the ultimate outcome of its efforts to mitigate the impact of any cost increases.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Quantitative and Qualitative Disclosures About Market Risk are reported under Item 2 MD&A “Other Matters — Market Risk Sensitive Instruments and Positions.”

ITEM 4. CONTROLS AND PROCEDURES

Alliant Energy’s, IP&L’s and WP&L’s management evaluated, with the participation of each of Alliant Energy’s, IP&L’s and WP&L’s Chief Executive Officer (CEO), Chief Financial Officer (CFO) and Disclosure Committee, the effectiveness of the design and operation of Alliant Energy’s, IP&L’s and WP&L’s disclosure controls and procedures as of the end of the quarter ended June 30, 2004 pursuant to the requirements of the Securities Exchange Act of 1934, as amended. Based on their evaluation, the CEO and the CFO concluded that Alliant Energy’s, IP&L’s and WP&L’s disclosure controls and procedures were effective as of the end of the quarter ended June 30, 2004.

There was no change in Alliant Energy’s, IP&L’s and WP&L’s internal control over financial reporting that occurred during the quarter ended June 30, 2004 that has materially affected, or is reasonably likely to materially affect, Alliant Energy’s, IP&L’s or WP&L’s internal control over financial reporting.

PART II — OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

ALLIANT ENERGY & WP&L
In the fourth quarter of 2003, the Wisconsin Environmental Law Advocates (WELA) filed a complaint in the U.S. District Court for the Western District of Wisconsin against WP&L and Alliant Energy alleging violations of the federal Clean Water Act at the Columbia generating station. The complaint sought certain upgrades to Columbia's wastewater treatment program, as well as unspecified penalties and attorney fees. In addition, the Wisconsin DNR has pursued enforcement of this same matter and referred the matter to the Wisconsin Department of Justice (WDOJ), who filed a complaint in the Circuit Court of Columbia County, Wisconsin. Alliant Energy, WDOJ and WELA have entered into a settlement agreement to resolve the matter, which has been accepted by the court. Under the settlement agreement, the joint owners of Columbia have agreed to pay a total of $150,000 in forfeitures, fees and other costs, plus implement certain new technical and operational requirements at the facility. Alliant Energy had established the necessary reserve for its respective costs at June 30, 2004. Alliant Energy believes that the total cost to resolve the matter and implement technical and operational requirements will not be material.
