RETIREMENT AND EMPLOYEE BENEFIT PLANS ALLIANT ENERGY CORPORATE SERVICES RETIREMENT PLANS

Alliant Energy Cash Balance Pension Plan

Salaried employees (including officers) of the Company are eligible to participate in a Retirementthe Alliant Energy Cash Balance Pension Plan (the “Pension Plan”) maintained by Alliant Energy Corporate Services. In 1998, the Retirement Plan was amended to implement a cash balance format, thereby changing the benefit calculation formulas and adding a lump sum distribution option for eligible participants. The Alliant Energy Cash Balance Pension Plan bases a participant'sparticipant’s defined benefit pension on the value of a hypothetical account balance. For individuals participating in the Pension Plan as of AugustAug. 1, 1998, a starting account balance was created equal to the present value of the benefit accrued as of DecemberDec. 31, 1997, under the Plan'sapplicable prior benefit formula prior to the change to a cash balance approach. That formula provided a retirement income based on years of credited service and final average compensation for the 36 highest consecutive months, with a reduction for a Social Security offset.formula. In addition, such individuals participating in the Plan as of August 1, 1998 received a special one-time transition credit amount equal to a specified percentage varying with age multiplied by credited service and base pay. For 1998 and thereafter, a participant receives annual credits to the account equal to 5% of base pay (including certain incentive payments, pre-tax deferrals and other items), plus an interest credit on all prior accruals equal to 4%, plus a potential share of the gain on the investment return on assets in the trust investment for the year.

The life annuity payable under the Pension Plan is determined by converting the hypothetical account balance credits into annuity form. Individuals who were participants in the Pension Plan on AugustAug. 1, 1998, are in no event to receive any less than what would have been provided under the prior formula that was applicable to them, had it continued, if they terminate on or before AugustbeforeAug. 1, 2008, and do not elect to commence benefits before the age of 55.

All of the individuals listed in the Summary Compensation Table who participate in the Pension Plan (Messrs. Davis, Protsch Harvey and Ms. Wegner) are "grandfathered"“grandfathered” under the applicable prior plan benefit formula. SinceBecause their estimated benefits under thatthe applicable prior plan benefit formula are higher than under the Pension Plan formula, utilizing current assumptions, their benefits would currently be determined by the applicable prior plan benefit formula. At the time of his resignation from the Company in November 2003, Mr. Walker had a vested balance of $68,056 in the Pension Plan.

REPORT OF THE COMPENSATION AND PERSONNEL

COMMITTEE ON EXECUTIVE COMPENSATION TO OUR SHAREOWNERS:

To Our Shareowners:

The Compensation and Personnel Committee (the "Committee"“Committee”) of the Board of Directors of the Company is currently comprised of four non-employeefive independent directors (the same directors that comprise the AEC Compensation and Personnel Committee). The following is a report prepared by these directors with respect to compensation paid by AEC, the Company and AEC'sAEC’s other subsidiaries.

The Committee assesses the effectiveness and competitiveness of, approves the design of and administers executive compensation programs within a consistent total compensation framework for the Company. The Committee also reviews and approves all salary arrangements and other remuneration for executives, evaluates executive performance, and considers related matters. It also makes recommendations to the Nominating and Governance Committee regarding Director compensation. To support the Committeeit in carrying out its mission, the Committee engages an independent consultant is engaged to provide assistance to the Committee. assistance.

The Committee is committed to implementing an overall compensation program for executives that furthers the Company'sCompany’s mission. Therefore, the Committee adheres to the following compensation policies, which are intended to facilitate the achievement of the Company'sCompany’s business strategies: -

Executive management compensation (and particularly, long-term incentive compensation) should be closely and strongly aligned with the long-term interests of AEC’s shareowners.

Total compensation should enhance the Company'sCompany’s ability to attract, retain and encourage the development of exceptionally knowledgeable and experienced executives, upon whom, in large part, the successful operation and management of the Company depends. - Base salary levels should be targeted at a competitive market range paid to executives of comparable companies. Specifically, the Committee targets the median (50th percentile) of base salaries paid by a selected group of utility and general industry companies. -

Base salary levels should be targeted at a competitive market range of base salaries paid to executives of comparable companies. Specifically, the Committee targets the median (50th percentile) of base salaries paid by companies within the utility and general industries.

Incentive compensation programs should strengthen the relationship between pay and performance by emphasizing variable, at-risk compensation that is consistent with meeting predetermined Company, subsidiary, business unit and individual performance goals. In addition, the Committee targets incentive levels are targeted at the median (50th percentile) of incentive compensation paid by a selected group ofsimilarly sized companies within the utility and general industry companies. COMPONENTS OF COMPENSATION industries.

Components of Compensation

The major elements of the Company'sAEC’s executive compensation program are base salary, short-term (annual) incentives and long-term (equity) incentives. These elements are addressed separately below. In setting the level for each major component of compensation, the Committee considers all elements of an executive'sexecutive’s total compensation package, including employee benefit and perquisite programs. The Committee'sCommittee’s goal is to provide an overall compensation package for each executive officer that is competitive to the packages offered other similarly situated executives. The Committee has determined that total executive compensation at target levels, including that for Mr. Davis, is in line with competitive compensation of the comparison group ofcomparative companies. BASE SALARIES

Base Salaries

The Committee annually reviews each executive'sexecutive’s base salary. Base salaries are targeted at a competitive market range (i.e., at the median level) when comparing both utility and non-utility (general industry) data. BaseThe Committee annually adjusts base salaries are adjusted annually by the Committee to recognize changes in the market, varying levels of responsibility, prior experience and breadth of knowledge. Increases to base salaries are driven primarily by market adjustments for a particular salary level, which generally limitlimits across-the-board increases. IndividualThe Committee considers individual performance factors are not considered by the Committee in setting base salaries. The Committee reviewed executive salaries for market comparability using utility and general industry data contained in compensation surveys published by the Edison Electric Institute, the American Gas Association and several compensation consulting firms. Based on

In consideration of industry conditions and Company performance, the foregoing,Committee did not increase the 25 annual salary for Mr. Davis was fixed at $640,000 for the 2000 fiscal year. SHORT-TERM INCENTIVES The goalbase salaries of the Company'sChief Executive Officer and the Executive Vice Presidents in 2003.

Short-Term Incentives

AEC’s short-term (annual) incentive programs is to promoteprogram promotes the Committee'sCommittee’s pay-for-performance philosophy by providing executives with direct financial incentives in the form of annual cash or stock based bonuses based ontied to the achievement of corporate, subsidiary, business unit and individual performance goals. Annual bonus opportunities allow the Committee to communicate specific goals that are of primary importance during the coming year and motivate executives to achieve these goals. The Committee on an annual basis reviews and approves the programs'program’s performance goals, and the relative weight assigned to each goal as well asand the targeted and maximum award levels. A description of the short-term incentive programs available during 20002003 to executive officers follows. ALLIANT ENERGY CORPORATION MANAGEMENT INCENTIVE COMPENSATION PLAN--

Alliant Energy Corporation Management Incentive Compensation PlanIn 2000,2003, the Alliant Energy Corporation Management Incentive Compensation Plan (the "MICP"“MICP”) covered executives and was based on achieving annual targets in corporate performance that included earnings per share ("EPS"(“EPS”), cash flow, safety, diversity and environmental targets for the utility businesses, and business unit (including customer service and reliability) and individual performance goals. Target and maximum bonus awards under the MICP in 20002003 were set at the median of the utility and general industry market levels. Targets wereThe Committee considered by the Committeethese targets to be achievable, but requiredto require above-average performance from each of the executives. The level of performance achieved in each category determines actual payment of bonuses, as a percentage of annual salary. Weighting factors are applied to the percentage achievement under each category to determine overall performance. If a pre-determined EPS target is not met, there is no bonus payment associated with the MICP. If the threshold performance for any other performance target is not reached, there is no bonus payment associated with that particular category. Once the designated maximum performance is reached, there is no additional payment for performance above the maximum level. The actual percentage of salary paid as a bonus, within the allowable range, is equal to the weighted average percent achievement for all the performance categories. Potential MICP awards range from 0% to 90%150% of annual salary for eligible executives other than Mr. Davis. The amounts paid under the MICP to eligible officers included in the Summary Compensation Table are reflected in that table. In 2000, Mr. Davis was covered by the MICP. Awards for Mr. Davis under the MICP in 2000 were based on corporate and strategic goal achievement in relation to predetermined goals. For each plan year, the Committee determines the performance apportionment for Mr. Davis. In 2000, that apportionment was 70% for corporate performance and 30% for strategic goal performance. Corporate performance is measured based on Company-wide EPS and environmental and safety targets established at the beginning of the year. Strategic goals are measured based on the achievement of certain specific goals, which included strategy development and implementation, established for Mr. Davis by the Committee. The 2000 MICP award range for Mr. Davis was from 0% to 150%100% of annual salary. The award earned by Mr. Davis undersalary for other eligible executives.

Due to industry and market conditions, the Committee determined that the Chief Executive Officer and Executive Vice Presidents were not eligible to receive MICP awards for 2000 is set forth in the Summary Compensation Table under the heading "Bonus". LONG-TERM INCENTIVES 2003 plan year performance.

Long-Term Incentives

The Committee strongly believes compensation for executives should include long-term, at-risk pay to strengthentostrengthen the alignment of the interests of the shareowners and management. In this regard, the Alliant Energy Corporation Long-Term Equity Incentive Plan permitsAEC maintains plans that permit grants of stock options, restricted stock and performance unit/ units/shares with respect to AEC'sAEC’s common stock. The Long-Term Equity Incentive Plan is administered by the AEC Compensation and Personnel Committee. The Committee believes that the Long-Term Equity Incentive Plan balancesincentive plans balance the Company's existingCompany’s annual compensation programs by emphasizing compensation based on the long-term, successful performance of the Company from the perspective of the shareowners of AEC.AEC’s shareowners. A description of the long-term incentive programs available during 20002003 to executive officers under the Long-Term Equity Incentive Plan is set forth below. ALLIANT ENERGY CORPORATION LONG-TERM INCENTIVE PROGRAM--The

Alliant Energy Corporation 26 Long-Term Incentive Program—The Alliant Energy Corporation Long-Term Incentive Program covered executives and consisted of the following components in 2000:2003: non-qualified stock options and performance shares. StockNon-qualified stock options provide a reward that is directly tied to the benefit shareowners of AEC receive from increases in the price of AEC'sAEC’s common stock. TheUntil 2003, the payout from the performance shares iswas based on two equally-weighted performance components: AEC'sAEC’s three-year total return to shareowners relative to an investor-owned utility peer group (“TSR”), and annualized EPS growth versus internally set performance hurdles contained in the Alliant Energy Strategic Plan. Beginning in 2003, TSR was used as the sole measure of the performance share plan. Thus, the two components of the Long-Term Incentive Program (i.e., stock options and performance shares) provide incentives for management to produce superior shareowner returns on both an absolute and relative basis. During 2000,2003, the AEC Compensation and Personnel Committee made a grant of stock options and performance shares to various executive officers, including Messrs. Davis, Harvey and Protsch Walker and Ms.Mses. Swan and Wegner.All option grants had per share exercise prices equal to the fair market value of a share of AEC common stock on the day following the date the grants were approved. Options vest on a one-third basis at the beginning of each calendar year after grant and have a ten-year10-year term from the date of the grant. Executives in the Alliant Energy Corporation Long-Term Equity Incentive ProgramSuch executives were also granted performance shares. Performance shares will be paid out in sharesa combination of AEC'sAEC common stock orand cash. The award will be modified by a performance multiplier, which ranges from 0 to 2.00 based on AECCompany performance.

In determining actual award levels under the Alliant Energy Corporation Long-Term Equity Incentive Program, the AEC Compensation and Personnel Committee was primarily concerned with providing a competitive total compensation opportunity level to officers. As such, award levels (including awards made to Mr. Davis) were based on a competitive analysis of similarly sized utility and general industry companies that took into consideration the market level of long-term incentives, as well as the competitiveness of the total

compensation package. AwardThe Committee then established award ranges as well asand individual award levels were then established based on responsibility level and market competitiveness. No corporate or individual performance measures were reviewed in connection with the awards of options and performance shares. Award levels were targeted to the median of the range of such awards paid by comparable companies. The AEC Compensation and Personnel Committee did not consider the amounts of options and performance shares already outstanding or previously granted when making awards for 2000.2003. Mr. Davis'Davis’ awards in 20002003 under the Long-Term Incentive Program are shown in the Stocktables under “Stock Option Grants in 2000 Table2003” and “Long-Term Incentive Awards in 2003.”

Due to the EPS and TSR goals not being achieved, there was no payout for the performance share portion of the Long-Term Incentive AwardsProgram’s three-year cycle that ended in 2000 Table. POLICY WITH RESPECT TO THEDecember 2003.

Policy with Respect to the $1 MILLION DEDUCTION LIMIT Million Deduction Limit

Section 162(m) of the Internal Revenue Code generally limits the corporate deduction for compensation paid to executive officers named in the proxy statement to $1 million unless such compensation is based upon performance objectives meetingobjectivesmeeting certain regulatory criteria or is otherwise excluded from the limitation. Based on the Committee'sCommittee’s commitment to link compensation with performance as described in this report, the Committee currently intends to qualify future compensation paid to the Company'sCompany’s executive officers for deductibility by the Company under Section 162(m) except in limited appropriate circumstances. CONCLUSION

Conclusion

The Committee believes the existing executive compensation policies and programs provide thean appropriate level of competitive compensation for the Company'sCompany’s executives. In addition, the Committee believes that the longlong- and short termshort-term performance incentives effectively align the interests of executives and shareowners toward a successful future for the Company.

STRATEGIC OVERVIEW

November 2002 Plan - In 2003, Alliant Energy (including WP&L) completed the plan it (including WP&L) outlined in November 2002 to strengthen its (including WP&L’s) financial profile. A summary of the strategic actions completed under the plan that directly impact WP&L is as follows:

Asset sales - in 2003, WP&L sold its water utility serving the Beloit area. WP&L continues to pursue the sale of its water utilities serving the Ripon and South Beloit areas.
Common equity offering - in July 2003, Alliant Energy sold 17.25 million shares (net proceeds of $318 million) of its common stock in a public offering and infused $200 million into WP&L in support of its utility generation and reliability initiatives.
Cost control - Alliant Energy (including WP&L) has implemented a comprehensive Lean Six Sigma program, which it expects to help reduce its operating costs and improve the efficiency of its operations.

Updated Strategic Plan - Alliant Energy’s domestic utility business (including WP&L) is its core business and the sole growth platform within its updated strategic plan. As a result, Alliant Energy views its domestic utility business as the area of its business that is expected to provide the larger share of its long-term earnings growth. It will also be the area of the business that Alliant Energy will invest the bulk of its capital in during 2004 and 2005. In addition, Alliant Energy’s Non-regulated Generation business has refined its focus to support the development, financing and construction of generation to meet the needs of Alliant Energy’s domestic utility business.

Alliant Energy’s updated strategy reflects the fact that it has investment opportunities in its domestic utility business that did not exist several years ago. Wisconsin enacted legislation with the goal of assuring reliable

electric energy for Wisconsin, which allows the construction of merchant power plants in the ratestate and streamlines the regulatory approval process for building new generation and transmission facilities. More recently, the PSCW approved a plan proposed by another Wisconsin utility which provides a similar level of inflation. UTILITY INDUSTRY OUTLOOK OVERVIEW--Asinvestment certainty by leasing generation from an affiliate. These changes have enabled WP&L to pursue additional generation investments to serve its customers and to provide Alliant Energy with greater certainty regarding the returns on these investments.

In December 2003, Alliant Energy announced its updated domestic utility generation plan, which is expected to add a diversified portfolio of nameplate generation between 2004 and 2010 for WP&L as follows (in MW):

Natural gas-fired generation

300

Wind (purchased-power and/or generation)

100

Coal

200

Other

15

Total

615

WP&L intends to add this new generation to meet increasing customer demand, reduce reliance on purchased-power agreements and mitigate the impacts of potential future plant retirements. WP&L will continue to purchase energy and capacity in the market and intends to remain a net purchaser of both, but at a reduced level assuming the successful completion of these generation projects. WP&L expects that 300 MW of the natural gas-fired generation will be installed as combustion turbines for peaking generation. The plan also reflects continued commitments to WP&L’s energy efficiency and environmental protection programs. WP&L’s capital expenditures associated with this plan are expected to be approximately $360 million over the seven-year period of 2004 to 2010.

In January 2004, Alliant Energy announced that Resources’ Non-regulated Generation business has assumed an option to purchase a site for a 300 MW natural gas-fired power plant outside Sheboygan Falls, Wisconsin. Subject to PSCW approval, Resources’ Non-regulated Generation business would construct and own the approximately $150 million plant (of which $75 million has been expended as of Dec. 31, 2003 to purchase two gas turbines) and lease the facility to WP&L. WP&L will operate the plant and utilize the plant’s output. With the appropriate timely regulatory approvals, Alliant Energy currently intends to have this facility placed in-service in 2005. In addition, Calpine Corporation is currently constructing a 600 MW natural gas-fired combined cycle power plant in Wisconsin at WP&L’s Rock River plant (Riverside). WP&L has entered into a purchased-power agreement for 453 MW of this plant’s output and the plant is expected to be placed in-service prior to the 2004 summer peak demand.

RATES AND REGULATORY MATTERS

Overview - WP&L, which has one utility subsidiary, South Beloit, is currently subject to federal regulation by FERC and state regulation in Wisconsin and Illinois. Such regulatory oversight covers not only current facilities and operations, but also WP&L’s plans for construction and financing of new generation facilities and related activities.

As a public utility company with significant utility assets, WP&L competesconducts its utility operations in an ever-changing utility industry.business environment. Electric energy generation, transmission and distribution are infacing a period of fundamental change resulting from potential legislative, regulatory, economic and technological changes. These changes could impact competition in the electric wholesale and retail markets asin the event customers of electric utilities are being offered alternative suppliers. Such competitive pressures could result in electric utilities losing customers and incurring stranded costs (i.e., assets and other costs rendered unrecoverable as the result of competitive pricing), which would be borne by security holders if the costs cannot be recovered from customers. WP&L is currently subject to regulation by FERC, and state regulation in Wisconsin and Illinois. FERC regulates competition in the electric wholesale power generation market and each state regulates whether

to permit retail competition, the terms of such retail competitionthat would apply and the recovery of any portion of stranded costs that are ultimately determined to have resulted from retail competition. WP&L cannot predict the timing of a restructured electric industry or the impact on its financial condition or results of operations but does believe it is well positioned to compete in a deregulated competitive market. Although WP&L ultimately believes that the electric industry will be deregulated, theoperations. The pace of deregulationrestructuring in its Wisconsinprimary retail electric service territories will likelyhas been delayed (and may continue to be delayed for a long period of time) due to recent eventsuncertainty and developments in the industry.

(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)A party representing selected commercial and industrial electric customers had appealed the rate case to a court, seeking remand back to the PSCW for further consideration on issues of revenue increase amount and rate design. In December 2003, the court denied the request for remand and affirmed the PSCW’s earlier decision.
(3)A number of factors contributed to the final rate relief being set lower than the original request, including lower projected fuel and purchased-power costs, reduced operation and maintenance costs, lower purchased-power incentive costs and reduced capital expenditures.
(4)Since the final increase was lower than the interim relief granted, a refund to customers was made in 2003.

A significant portion of the rate increases included in the previous table reflect the recovery of increased costs incurred by WP&L, or costs it expects to incur, thus the total increase in revenues related to California's restructured electric utility industry. In 1999, Wisconsin enacted "Reliability 2000" legislation which included, among other items, the formation of a Wisconsin transmission company (American Transmission Company,these rate increases have not or ATC) for those Wisconsin utility holding companies who elected to take advantage of the modified asset cap law and others who elected to join. ATC received all necessary regulatory approvals and began operations on January 1, 2001. WP&L, including South Beloit, transferred its transmission assets (approximate net book value of $177 million) to ATC on January 1, 2001. WP&L will receive cash of $88 million in 2001 and currently has an $89 million equity investment in ATC, resulting in no gain or loss for WP&L. WP&L doesare not expect this transferexpected to result in a significant impact on its financial condition or results of operations because it believes FERC will allow WP&L to earn a return on the contributed assets A-4 MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (CONTINUED) comparable to the return currently allowed by the PSCW and FERC. In addition to transferring its transmission assets, WP&L also transferred ownership of its System Operations Center to ATC. WP&L's ownership percentagecorresponding increase in ATC is approximately 26 percent and its investment is accounted for under the equity method. Although no assurance can be given, it is currently anticipated that ATC's dividend policy will support a return of a significant portion of these earnings to the equity holders. ATC is expected to realize its revenues from the provision of transmission services to both participants in ATC as well as nonparticipants. ATC's current rates are subject to refund pending final approval by FERC. ATC is a transmission-owning member of the Midwest ISO and the Mid-America Interconnected Network, Inc. Regional Reliability Council. net income.

WP&L's transfer of its transmission assets to ATC and its participation in the Midwest ISO are expected to comply with the provisions of a FERC order requiring utilities to turn over voluntarily the operational control of their transmission systems to a regional entity by the end of 2001. RATES AND REGULATORY MATTERS--As part of its merger approval, FERC accepted a proposal by WP&L which provides for a four-year freeze on wholesale electric prices beginning with the effective date of the April 1998 merger forming Alliant Energy. WP&L also agreed with the PSCW to provide customers a four-year retail electric and gas price freeze (the ICC granted South Beloit a three-year rate freeze), excluding the electric FAC and PGA clause, which commenced on the effective date of the April 1998 merger. In Wisconsin, a re-opening of an investigation into WP&L's rates during the rate freeze period, for both cost increases and decreases, may occur only for single events that are not merger-related and have a revenue requirement impact of $4.5 million or more. Assuming capture of the merger-related synergies and no significant legislative or regulatory changes negatively affecting its utility subsidiaries, WP&L does not expect the merger-related electric and gas price freezes to have a material adverse effect on its financial condition or results of operations. In connection with a statewide docket to investigate compliance issues associated with the EPA's NOx emission reductions, in March 1999, the PSCW authorized deferral of all incremental NOx compliance costs excluding internal labor and replacement purchased-power costs. In March 2000, the PSCW issued an order approving WP&L's NOx compliance plans, including additional investments at several WP&L generating units. The order also approved a 10-year straight-line depreciation method for NOx compliance investments. Such depreciation is also being deferred and WP&L anticipates recovery of all deferred NOx compliance costs beginning with the first rate changes after the rate freeze expires. The depreciation lives will be reviewed every two years. Refer to "Liquidity and Capital Resources--Environmental" for further discussion of the NOx issue. WP&L's&L’s retail electric rates are based in part on annual forecasted fuel and purchased-power costs. Under PSCW rules, WP&L can seek emergency rate increases if it experiences an extraordinary increase in the cost of fuel or if the annual fuel and purchased-power costs are more than 3 percent3% higher than the estimated costs used to establish rates. If WP&L's earnings exceed its authorized return on equity, the incremental revenues collected causing the excessive return are subject to refund. In December 2000,Such rules were revised effective for 2003 for WP&L requested a $73 million (revisedand significantly reduce the regulatory lag for Wisconsin utilities and customers related to $64 million) annual retail electric rate increase from the PSCW to cover increasestiming of changes in WP&L's 2001rates for increased or decreased fuel and purchased-power costs. The revised rules require that an interim increase/decrease in rates subject to increased/decreased fuel costs, dueif determined to the continued increasesbe justified, be approved within 21 days of notice to customers. Any such change in natural gas prices which impact WP&L's generationrates would be effective prospectively, would require a refund with interest if final rates are determined to be lower than interim rates approved, and would not include a provision for collection of retroactive fuel cost variances. The revised rules also include a process whereby Wisconsin utilities can seek deferral treatment of emergency changes in fuel costs between fuel-only or base rate cases. Such deferrals would be subject to review, approval and the increased costs of purchased-power. The PSCW approved a $46 million interim retail electricrecovery in future fuel-only or base rate increase effective February 9, 2001. A decision on a permanent rate increasecases.

Energy-related legislation is expectedcurrently pending in the second quarter of 2001. The PSCW also grantedU.S. Congress that, among other proposals, would repeal PUHCA. However, it is uncertain when or whether such legislation will be enacted or what impact it would have on WP&L annual retail electric rate increases of $14.8 million, $14.5 million and A-5 MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND &L.

RESULTS OF OPERATIONS (CONTINUED) $16.5 million in July 1998, March 1999 and May 2000, respectively, due to higher fuel and purchased-power costs, some of which have been caused by the transmission constraints and electric reliability concerns in the Midwest.

Overview - WP&L does not believe any revenues collected to date are subject to refund. In November 1999, the PSCW allowed WP&L rate recovery of $6.3 million of its Year 2000 (Y2K) program expenditures, but it denied rate recovery of the first $4.5 million. These costs were expensed in 1999. The PSCW's decision to allow rate recovery was appealed by certain intervenors in Dane County, Wisconsin district court. In April 2000, the intervenors withdrew their appeal. WP&L began recovering such costs in May 2000 and is amortizing the deferred costs as the amounts are recovered in rates. In February 2000, the PSCW issued an order allowing WP&L to defer certain incremental costs it incurred after February 16, 2000 relating to the development of ATC. In December 2000, the PSCW issued an order allowing WP&L to defer incremental operating costs associated with ATC. Recovery of such costs will be addressed in WP&L's next retail rate case. In 2000, the NRC raised several areas of concern with Kewaunee's operations. The concerns raised by the NRC are estimated to result in additional operating costs to WP&L in 2001 of approximately $5 million. Additional operating costs to WP&L over the period of 2002 through 2005 are estimated to be approximately $20 million and will be included in a future rate request. WP&L submitted a request to the PSCW for deferral of incremental costs associated with this issue. The NRC has acknowledged the safety record of Kewaunee and its ability to continue operations. WP&L is in the process of pursuing a rate complaint against Union Pacific Railroad with the STB. WP&L believes Union Pacific Railroad is charging an excessive rate for transporting low-sulfur coal from the Powder River Basin to the Edgewater Generating Station located in Sheboygan, Wisconsin. To contest the rate, WP&L filed a rate case with the STB and upon the expiration of the existing contract, began moving coal under a tariff rate beginning January 1, 2000. Final briefs were filed in December 2000 and the STB has until September 2001 to issue a final decision. If the STB rules in WP&L's favor, a refund to WP&L's customers will need to be considered in conjunction with the electric FAC in Wisconsin. WP&L complies with the provisions of SFAS 71, "Accounting for the Effects of Certain Types of Regulation." SFAS 71 provides that rate-regulated public utilities record certain costs and credits allowed in the rate making process in different periods than for non-regulated entities. These are deferred as regulatory assets or accrued as regulatory liabilities and are recognized in the Consolidated Statements of Income at the time they are reflected in rates. If a portion of WP&L's operations no longer complies with SFAS 71, a write-down of related regulatory assets and possibly other charges would be required, unless some form of transition cost recovery is established by the appropriate regulatory body that meets the requirements under generally accepted accounting principles for continued accounting as regulatory assets during such recovery period. In addition, WP&L would be required to determine any impairment of other assets and write-down any impaired assets to their fair value. WP&L believes it currently meets the requirements of SFAS 71. RESULTS OF OPERATIONS OVERVIEW--WP&L's&L’s earnings available for common stock increased $0.6$34.0 million and $35.3$7.4 million in 20002003 and 1999, respectively. The 2000 increase was2002, respectively, primarily due to higher electric margins and a reduced effective income tax rate, largely offset by increased operation and maintenance, depreciation and amortization and interest expenses. The 1999 increase was primarily due to the nonrecurrence of $17.3 million of merger-related expenses in 1998, higher electric and natural gas margins, reduced other A-6 MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (CONTINUED) operation and maintenance expenses and income realized from weather hedges. Such increases were partially offset by increased depreciation and amortization expense (excluding hedge losses in WP&L's nuclear decommissioning trust fund) and higher interest expense.

Electric margin increased $23.6$65.2 million, or 6%15%, and $28.2$19.7 million, or 7%5%, during 2000for 2003 and 1999, respectively. The 2000 increase was2002, respectively, primarily due to the implementation of rate increases during 2003 and 2002, including increased revenues to recover a significant portion of WP&L’s increased operating expenses and increased sales from continued modest retail customer growth. Also contributing to retail customers duethe 2003 increase were the impact of WP&L implementing seasonal rates in 2003 for the first time, lower purchased-power and fuel costs impacting margin and higher sales to continued economic growth in WP&L's service territory, a favorable $10 million change in estimate of utility services rendered but unbilled at month-end and increased energy conservation revenues.non-retail customers. These items were partially offset by lower energy conservation revenues and the impact of milder weather conditions in 20002003 compared to 1999 and higher purchased-power and fuel expenses. The 19992002. Also contributing to the 2002 increase was primarily due to separate $15 million annual rate adjustments implemented at WP&L in July 1998 and March 1999 to recover higher purchased-power and transmission costs. An increase in retail sales of 3% due towere more favorable weather conditions in 2002 compared to 2001, partially offset by the sluggish economy.

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 economic growth within WP&L's service territory also contributedlower rates in all other periods during each calendar year. As a result, total annual revenues are not expected to be impacted significantly. However, given the seasonal rates were not implemented in 2003 until April, the impact of seasonal rates increased electric margins by approximately $6 million in 2003 compared to 2002 when no seasonal rates were in effect. As a result, the first quarter of 2004 margins are expected to be negatively impacted in comparison to the increase. Partially offsetting2003 margin for the 1999 increase were lower sales to off-system and wholesale customers due to transmission constraints and decreased contractual commitments and $3.2 million of revenues collected in 1998 forsame period by a surcharge related to Kewaunee.

These increases alone had little impact on WP&L’s gas margin given its rate recovery mechanism for gas costs. Gas margin increased $1.3$17.1 million, or 2%25%, and $6.4$15.9 million, or 13%30%, for 2003 and 2002, respectively, primarily due to the impact of rate increases implemented during 20002003 and 1999,2002, improved performance of $3 million from WP&L’s performance-based commodity cost recovery program (benefits are shared by ratepayers and shareowners), and continued modest customer growth. The 2002 increase was also due to the negative impact high gas prices in early 2001 had on gas consumption during that period.

Refer to Note 1(h) of the “Notes to Consolidated Financial Statements” for information relating to utility fuel and natural gas cost recovery.

Other Revenues - Other revenues increased $11.8 million and decreased $10.6 million for 2003 and 2002, respectively. The 20002003 increase was primarily due to increased revenues from WindConnect. The 2002 decrease was primarily due to decreased non-commodity products and services revenues. These 2003 and 2002 variances were largely offset by variances in other operation and maintenance expenses.

Other Operating Expenses - Other operation and maintenance expenses increased $52.9 million and $28.7 million for 2003 and 2002, respectively. The 2003 increase was largely due to more favorable weather conditionsincreases in the 2000 heating season compared to 1999, partially offset by reduced energy conservation revenues.

The 2000 increase was primarily due to increased earnings in the nuclear decommissioning trust fund of approximately $20 million, property additions and higher amortization expense. The 1999 decrease was due to reduced earnings in the nuclear decommissioning trust fund and the nonrecurrence of the $3.2 million Kewaunee surcharge in 1998. The 1999 decrease was partially offset by the impact of property additions. The accounting for earnings on the nuclear decommissioning A-8 MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (CONTINUED) trust funds results in no net income impact. Miscellaneous, net income is increased for earnings on the trust fund, which is offset in depreciation expense. INTEREST EXPENSE AND OTHER--Interest expense increased $3.7 million and $4.4 million in 2000 and 1999, respectively. The 2000 increase was primarily due to higher interest rates and borrowings outstanding in 2000. The 1999 increase was primarily due to higher short-term borrowings. Miscellaneous, net income increased $18.4 million and decreased $3.0 million in 2000 and 1999, respectively. The 2000 increase was primarily due to increased earnings in the nuclear decommissioning trust fund of approximately $20 million, partially offset by reduced income of $2 million realized from gas weather hedges. The 19992003 decrease was primarily due to lower earnings on the nuclear decommissioning trust fund,software amortizations, partially offset by property additions. The 2002 decrease was largely due to lower decommissioning expense based on reduced retail funding levels, partially offset by higher software amortizations.

Interest Expense and Other - Interest expense decreased $2.3 million and $3.3 million for 2003 and 2002, respectively. The 2003 decrease was largely due to lower average borrowings outstanding. The 2002 decrease was largely due to lower average interest rates on the nonrecurrence of $6.1outstanding borrowings. Equity income from unconsolidated investments increased $3.7 million of merger-related expenses in 1998for 2003 due to higher earnings at WRPC and $5 million recognized in 1999 associated with the settlement of gas weather hedges.

WP&L expects&L’s cash flows are expected to meet its future capital requirements with cash generated from operations and external financing. The level of cash generated from operations is partially dependent on economic conditions, legislative activities, environmental matters and timely regulatory recovery of utility costs. Liquiditycover dividends and capital resources will be affected by costsexpenditures related to infrastructure and reliability investments. WP&L’s capital expenditures associated with environmentalbuilding additional generation are expected to total $360 million through 2010 and regulatory issues.

In 2003, WP&L's liquidity and capital resources, as discussed in "Utility Industry Outlook." CASH FLOWS--In 2000, WP&L's cash flows used for financing activities increased $20 million due to the reduction of short-term debt outstanding and a capital contribution of $30 million in 1999 from Alliant Energy, partially offset by the issuance of $100 million of senior unsecured debentures in 2000 and no common stock dividends declared in 2000 due to management of its capital structure.

ENVIRONMENTAL--WP&L's pollution abatement programs are subjectproceeds received from the transfer of WP&L’s transmission assets to continuing review and are periodically revised due to changesATC in environmental regulations, construction plans and escalation of construction costs. While management cannot precisely forecast the effect of future environmental regulations on operations, it has taken steps to anticipate the future while also meeting the requirements of current environmental regulations. A-9 MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (CONTINUED) Wisconsin is subject to the Clean Air Act due to its non-attainment status with respect to the one-hour ozone standard in the Lake Michigan region. The WDNR has developed a rule that contains a plan for the state to meet the one-hour ozone attainment standard. The plan focuses on rate of progress requirements that are specified2001.

State Regulatory Approvals - At Dec. 31, 2003, WP&L was authorized by the Clean Air Act for the years 2002, 2005 and 2007. The rule requires NOx reductions in counties that are currently in non-attainmentappropriate state regulatory agencies to issue short-term debt of the one-hour ozone standard$240 million, which includes WP&L's Edgewater power plant.$85 million for general corporate purposes, an additional $100 million should WP&L is currently evaluating various alternativesno longer sell its utility receivables and an additional $55 million should WP&L need to achieve the proposed reductionsrepurchase its variable rate bonds.

Based on existing technology, preliminary estimates indicate that capital investments in the rangeTemporary Cash Investments - As of $30 to $40Dec. 31, 2003, WP&L had approximately $27 million could be required. Revisions to the Wisconsin Administrative Code have been proposed that could have a significant impact on WP&L's operation of the Rock River Generating Station in Beloit, Wisconsin. The proposed revisions will affect the amountcash and temporary cash investments.

Sale of heat that the generating station can discharge into the Rock River. WP&L cannot presently predict the final outcome of the rule, but believes that, as the rule is currently proposed, the capital investments and/or modifications required to meet the proposed discharge limits could be significant. In 1998, the EPA issued the final report to Congress on the Study of Hazardous Air Pollutant Emissions (HAPs) from Electric Utility Steam Generating Units regarding hazardous air pollutant emissions from electric utilities, which concluded that mercury emissions from coal-fired generating plants were a concern. The EPA is developing regulations that are expected to be in place by 2004. In December 2000, the EPA made a regulatory determination in favor of controlling HAPs (including mercury) from electric utilities, which is being challenged by utility industry groups in two lawsuits filed in February 2001. Although the control of mercury emissions from generating plants is uncertain at this time, WP&L believes that the capital investments and/or modifications that may be required to control mercury emissions could be significant. Also in December 2000, the WNRB voted to allow the WDNR to proceed with mercury rulemaking. WP&L and the other Wisconsin Utility Association members have recommended to WNRB a workable mercury program that protects reliability and does not disadvantage Wisconsin when federal mercury rules are developed. The WDNR has indicated its desire to have the proposed rule written by the Spring of 2001. WP&L cannot presently predict the final outcome of the regulation, but believes that capital investments and/or modifications required could be significant. WP&L has been notified by the EPA that it is a PRP with respect to the MIG/DeWane Landfill Superfund Site. WP&L is participating in the initiation of an alternate dispute resolution process to allocate liability associated with the investigation and remediation of the site. Management believes that any likely action resulting from this matter will not have a material adverse effect on WP&L's financial condition or results of operations. In 2000, WP&L was notified by Monroe County, Wisconsin that it does not have liability for costs associated with the Monroe County Interim Landfill in Sparta, Wisconsin. Monroe County has decided that it will pay for the investigation and cleanup of the landfill through community-wide funding. In December 2000 and February 2001, the EPA requested certain information relating to the historical operation of WP&L's major coal-fired generating units in Wisconsin. WP&L has responded to the December 2000 request and is in the process of preparing its response to the February 2001 request. In some cases involving similar EPA requests from other electric generating facilities, penalties and capital A-10 MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (CONTINUED) expenditures have resulted. WP&L cannot presently predict what impact, if any, the EPA's request may have on its financial condition or results of operations. However, any required remedial action resulting from this matter could be significant. A global treaty has been negotiated that could require reductions of greenhouse gas emissions from utility plants. In 1998, the U.S. signed the treaty and agreed with other countries to resolve all remaining issues by the end of 2000. That deadline has not been met and significant differences remain between the U.S. and other countries. At this time, management is unable to predict whether the U.S. Congress will ratify the treaty. Given the uncertainty of the treaty ratification and the ultimate terms of the final regulations, management cannot currently estimate the impact the implementation of the treaty would have on WP&L's operations.Accounts Receivable - Refer to Note 11(e)4 of the "Notes“Notes to Consolidated Financial Statements"Statements” for further discussioninformation on WP&L’s sale of WP&L's environmental matters.

The net proceeds were primarily usedavailable for direct borrowing or to repay short-term debt.support commercial paper. WP&L has $150 millionthe option to convert the facility into a one-year term loan. It is expected that WP&L will be able to renew or replace the facility on favorable terms when it matures in 2004. The credit facility agreement contains various covenants, including a requirement to maintain a debt-to-capital ratio of long-termless than 58%. At Dec. 31, 2003, WP&L’s debt-to-capital ratio was 29.9%. The debt that will mature prior to December 31, 2005. Depending on market conditions, it is anticipated that a majoritycomponent of the maturingcapital ratio includes long- and short-term debt will be refinanced with the issuance(excluding

Refer to Note 8(b)credit and guarantees of the "Notes to Consolidated Financial Statements" for additional information on long-term debt. SHORT-TERM DEBT--Inforegoing and unfunded vested benefits under qualified pension plans. The equity component excludes accumulated other comprehensive income (loss).

In addition to funding working capital needs, the availability of short-term financing provides WP&L flexibility in the issuance of long-term securities. The level of short-term borrowing fluctuates based on seasonal corporate needs, the timing of long-term financingfinancings and capital market conditions. At DecemberWP&L did not have any commercial paper outstanding at Dec. 31, 2000, WP&L2003 and information regarding commercial paper during 2003 was authorized by the applicable federal or state regulatory agency to issue short-term debtas follows (in millions):

WP&L’s credit facility contains a negative pledge provision, which generally prohibits placing liens on any of $128 million. WP&L, IESU and IPC participate in a utility money pool that is funded, as needed, through&L’s property with certain exceptions, including among others, for the issuance of commercial paper bysecured debt under WP&L’s first mortgage bond indentures, non-recourse project financing and purchase money liens.

WP&L’s credit facility contains a material adverse change (MAC) clause. Before each extension of credit (each borrowing under the facility), WP&L must represent and warrant that no MAC has occurred since Dec. 31, 2002. A MAC is defined as a change that would create: (1) a MAC in, or a material adverse effect upon, the operations, business, properties, liabilities (actual or contingent), condition (financial or otherwise) or prospects of the borrower or the borrower and its subsidiaries taken as a whole; (2) a material impairment of the ability of the borrower to perform its obligations under a credit facility agreement to which it is a party; or (3) a MAC upon the legality, validity, binding effect or enforceability against the borrower of any credit agreement to which it is a party.

WP&L’s credit facility contains a provision that requires, during the term of the facility, any proceeds from asset sales, with certain exclusions, in excess of 5% of WP&L’s consolidated assets in any 12-month period be used to reduce commitments under its facility. Exclusions include, among others, certain intercompany sales and certain sale and lease-back transactions.

Long-term Debt - In September 2003, WP&L retired $70 million of its 8.6% first mortgage bonds due 2027 largely from proceeds of a capital contribution from Alliant Energy. Interest expense and other fees are allocated based on borrowing amounts. The PSCW has restricted

Credit Ratings and Balance Sheet - Access to the capital and credit markets, and costs of obtaining external financing, are dependent on creditworthiness. WP&L is committed to taking the necessary steps required to maintain flexibilityinvestment-grade credit ratings and a strong balance sheet. Refer to “Strategic Overview - November 2002 Plan” for discussion of specific actions taken in this regard. Although WP&L believes the actions taken in 2003 to strengthen its balance sheet will enable it to maintain investment-grade credit ratings, no assurance can be given that it will be able to maintain its existing credit ratings. If WP&L’s credit ratings are downgraded in the future, then WP&L’s borrowing costs may increase and its access to capital structuremarkets may be limited. If access to capital markets becomes significantly constrained, then WP&L’s results of operations and financial condition could be materially adversely affected.

Ratings Triggers - The long-term debt of WP&L is not subject to any repayment requirements as a result of explicit credit rating downgrades or so-called “ratings triggers.” Pre-existing ratings triggers in certain lease agreements were eliminated during 2003. However, WP&L is party to various agreements, including purchased-power agreements, fuel contracts and accounts receivable sale contracts that are dependent on maintaining investment-grade credit ratings. In the event of a downgrade below investment-grade, WP&L may need to provide credit support, such as letters of credit or cash collateral equal to the amount of the exposure, or may need to unwind the contract or pay the underlying obligation. WP&L is party to an accounts receivable sale agreement that provides that a downgrade below investment-grade causes WP&L to become ineligible to sell receivables under the program. In the event of downgrades below investment-grade, management believes the credit facility at WP&L provides sufficient liquidity to cover counterparty credit support or collateral requirements under the various purchased-power, fuel and receivables sales agreements.

Off-Balance Sheet Arrangements - WP&L utilizes off-balance sheet synthetic operating leases to finance certain utility railcars and a utility radio dispatch system. Synthetic leases provide favorable short-termfinancing rates to WP&L while allowing it to maintain operating control of its leased assets. Refer to Note 3 of the “Notes to Consolidated Financial Statements” for future minimum lease payments under, and residual value guarantees by WP&L, of these synthetic leases. WP&L’s credit facility agreement prohibits it from entering into any additional synthetic leases. WP&L uses special purpose entities for its limited recourse utility sale of accounts receivable program whereby WP&L uses proceeds from the sale of the accounts receivable and unbilled revenues to maintain flexibility in its capital structure, take advantage of favorable short-term interest rates and finance a portion of its long-term cash needs. WP&L has filed applications with the SEC and state regulatory agenciesThe sale of accounts receivables generates a significant amount of short-term financing for approval of a combined accounts receivable sale program whereby WP&L, IESU and IPC will sell their respective receivables through wholly-owned special purpose entities to an affiliated financing entity, which in turn will sell the receivables to an outside investor. The new program would replace the existing program for WP&L, and would be substantially similar to the prior program. All necessary approvals are expected by mid-2001. FINANCIAL COMMITMENTS--Refer&L. Refer to Note 11(d)4 of the "Notes“Notes to Consolidated Financial Statements"Statements” for information. A-11 MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (CONTINUED) CONSTRUCTION AND ACQUISITION EXPENDITURES--Capital expenditureaggregate proceeds from the sale of accounts receivable. While WP&L does not have any reason to believe this program would be discontinued, if this financing alternative were not available, WP&L anticipates it would have enough short-term borrowing capacity to compensate. Refer to “Ratings Triggers” for the impact of certain credit rating downgrades on WP&L related to the accounts receivable sales program. WP&L has reviewed these entities during its implementation of FIN 46, for those entities that are considered to be special-purpose entities, and investmentdetermined that consolidation of these entities is not required. WP&L continues to evaluate non-special purpose entities that may require consolidation as of March 31, 2004.

Sales of Non-strategic Assets - WP&L is currently pursuing the sales in 2004 of its interest in its Kewaunee facility and its water utilities serving the Ripon and South Beloit areas. The proceeds realized from these asset sales are expected to be available for debt reduction and other general corporate purposes.

Credit Risk - WP&L has limited credit exposure from electric and natural gas sales and non-performance of contractual obligations by its counterparties. WP&L maintains credit risk oversight and sets limits and policies with regards to its counterparties, which management believes minimizes its overall credit risk exposure. However, there is no assurance that such policies will protect WP&L against all losses from non-performance by counterparties.

Construction and Acquisition Expenditures - Capital expenditures, investments and financing plans are continually reviewed, approved and updated as part of WP&L’s ongoing strategic planning and budgeting processes. In addition, material capital expenditures and investments are subject to change as a rigorous cross-functional review prior to approval. Changes in WP&L’s anticipated construction and acquisition expenditures may result from a number of many considerations, including: changes inreasons including economic conditions; variations in actual sales and load growth compared to forecasts;conditions, regulatory requirements, of environmental, nuclear and other regulatory authorities; acquisition and business combination opportunities; the availability of alternate energy and purchased-power sources; the ability to obtain adequate and timely rate relief; escalationsrelief, the level of WP&L’s profitability, WP&L’s desire to maintain investment-grade credit ratings and reasonable capitalization ratios, variations in construction costs;sales, changing market conditions and conservation and energy efficiency programs.new opportunities. WP&L believes its capital control processes adequately reduce the risks associated with large capital expenditures and investments.

WP&L currently anticipates financingits construction and acquisition expenditures for utility infrastructure and reliability investments to be $228 million in 2004 and $248 million in 2005. WP&L has not yet entered into contractual

commitments relating to the majority of its anticipated capital expenditures. As a result, WP&L does have discretion with regard to the level of capital expenditures eventually incurred and it closely monitors and updates such estimates on an ongoing basis based on numerous economic and other factors. Refer to “Strategic Overview - Updated Strategic Plan” for further discussion of Alliant Energy’s domestic generation plan.

At Dec. 31, 2003, long-term debt as noted in the previous table was included on the Consolidated Balance Sheet and excludes reductions related to unamortized debt discounts. Purchased-power and fuel commitments represent normal business contracts used to ensure adequate purchased-power, coal and natural gas supplies and to minimize exposure to market price fluctuations. Other purchase obligations represent individual commitments incurred during the normal course of business which exceeded $1 million at Dec. 31, 2003. Alliant Energy has entered into various coal and purchased-power commitments that have not yet been directly assigned to WP&L and IP&L. Such commitments are not included in WP&L’s purchase obligations. In connection with its construction expenditures during 2001-2005 through internally generated funds supplemented, when required, by outside financing.and acquisition program, WP&L also enters into commitments related to such programs on an ongoing basis; these amounts are not reflected in the previous table. Refer to “Construction and Acquisition Expenditures” for additional information. In addition, at Dec. 31, 2003, there were various other long-term liabilities and deferred credits included on the Consolidated Balance Sheet that, due to the nature of the liabilities, the timing of payments cannot be estimated and are therefore excluded from the table. Refer to Note 11(a)6 of the "Notes“Notes to Consolidated Financial Statements"Statements” for informationanticipated 2004 pension and other postretirement benefit funding amounts, which are not included in the previous table.

Environmental - WP&L’s pollution abatement programs are subject to continuing review and are periodically revised due to changes in environmental regulations, construction plans and escalation of construction costs. WP&L continually evaluates the impact of potential future federal, state and local environmental rulemakings on its operations. While the final outcome of these rule makings cannot be predicted, WP&L believes that required capital investments and/or modifications resulting from them could be significant, but expects that prudent expenses incurred by WP&L likely would be recovered in rates from its customers. The environmental rulemaking process continually evolves and the following are major emerging issues that could potentially have a significant impact on WP&L's&L’s operations.

Air Quality - With regard to current environmental rules, WP&L’s Edgewater facility spent $21 million from 1999 to 2003 to improve its combustion performance. This facility now meets the 2008 Wisconsin DNR NOx compliance goal.

WP&L also has responded to multiple data requests from the EPA, related to the historical operation and associated air permitting for certain major Wisconsin coal-fired generating units. Similar requests have been precursor to penalties and capital expenditures requiring installation of air pollution controls at other utilities. However, WP&L has received no response in this regard from the EPA related to information submitted.

The 1990 CAA Amendments mandate preservation of air quality through existing regulations and periodic reviews to ensure adequacy of these provisions based on scientific data. In 1997, the EPA revised National

Ambient Air Quality Standards (NAAQS) for ozone and fine particulate matter. In December 2003, the EPA proposed an Interstate Air Quality Rule related to transport of these emissions that would require significant upgrades to power plants. This rule would reduce the current level of nationwide sulfur dioxide emissions approximately 40% by 2010 and 70% by 2015, and NOx emission levels 50% by 2015. Additional reduction requirements may also be imposed at the state level for those areas that are in non-attainment with NAAQS.

In 2000, the EPA determined that regulation of hazardous air pollutant emissions from coal-fired and oil-fired electric utility steam generating units was necessary. Under an existing settlement agreement, Maximum Achievable Control Technology requirements or alternative regulations must be implemented by Dec. 15, 2004. Accordingly, the EPA has published rules for comment requiring control of mercury from coal-fired and nickel from oil-fired generating units. The impact of these regulations on WP&L’s generating facilities is subject to the control level mandated in the final rules. In 2001, the Wisconsin DNR also independently developed proposed mercury emission control rules that could require reductions from Wisconsin generating facilities of 40% by 2010 and 80% by 2015. These rules have been sent back to the Wisconsin DNR for revision by the Wisconsin legislature due to the pending federal mercury regulations.

WP&L is also currently monitoring various other potential federal, state and local environmental rulemakings and activities, including, but not limited to: litigation of federal New Source Review Reforms; Regional Haze evaluations for Best Available Retrofit Technology; and several other legislative and regulatory proposals regarding the control of emissions of air pollutants and greenhouse gases from a variety of sources, including generating facilities.

Water Quality - In 2002, the EPA published a proposed regulation under the Clean Water Act referred to as “316(b)” that is anticipated to be finalized in 2004. This rule would require existing large power plants with cooling water intake structures to ensure that the location, design, construction, and acquisition expenditures. capacity of cooling water intake structures reflect the best technology available for minimizing adverse environmental impacts to fish and other aquatic life. WP&L is also currently evaluating proposed revisions to the Wisconsin Administrative Code concerning the amount of heat that WP&L’s generating stations can discharge into Wisconsin waters.

Land and Solid Waste - WP&L is monitoring possible significant land and solid waste regulatory changes. This includes a potential EPA regulation for management of coal combustion product in landfills and surface impoundments that could require installation of monitoring wells at some facilities and an ongoing expanded groundwater monitoring program. Compliance with the polychlorinated biphenols (PCB) Fix-it Rule/Persistent Organic Pollutants Treaty could possibly require replacement of all electrical equipment containing PCB insulating fluid which is a substance known to be harmful to human health. The Wisconsin Department of Commerce is proposing new rules related to flammable, combustible and hazardous liquids stored in above-ground storage tanks in which the main financial impact would be from a secondary containment requirement for all hazardous materials tanks and for hazardous material unloading areas. In addition, in December 2003, at the request of the Wisconsin DNR, WP&L submitted a written plan for facility closure of the Rock River Generating Station landfill and clean-up of the support ponds and all areas where coal combustion waste is present.

Refer to Note 11(e) of the “Notes to Consolidated Financial Statements” for further discussion of environmental matters.

OTHER MATTERS MARKET RISK SENSITIVE INSTRUMENTS AND POSITIONS

Market Risk Sensitive Instruments and Positions - WP&L's&L’s primary market risk exposures are associated with interest rates and commodity prices and equity prices.

Assuming no change in WP&L's&L’s consolidated financial structure, if variable interest rates were to average 1 percent100 basis points higher (lower) in 2001 compared to 2000, and2004 than in 2000 compared to 1999,2003, interest expense and pre-tax earnings would increase (decrease) by approximately $0.6 million for both time periods. These amounts were$1.2 million. This amount was determined by considering the impact of a hypothetical 1 percent100 basis point increase (decrease) in interest rates on theWP&L’s consolidated variable-rate debt held, bythe amount outstanding under the utility customer accounts receivable sale program and variable-rate lease balances at Dec. 31, 2003.

Commodity Risk - Non-trading - WP&L as of December 31, 2000 and 1999. COMMODITY RISK--NON-TRADING--WP&L is exposed to the impact of market fluctuations in the commodity price and transportation costs of electricityelectric and natural gas products it markets. WP&L employs established policies and procedures to manage its risks associated with these market fluctuations including the use of various commodity derivatives. WP&L's&L’s exposure to commodity price risks is significantly mitigated by the current rate making structures in place for the recovery of its electric fuel and purchased energy costs as well as its cost of natural gas purchased for resale. Refer to Note 1(i)1(h) of the "Notes“Notes to Consolidated Financial Statements"Statements” for further discussion.

WP&L periodically utilizes gas commodity swap arrangementsderivative instruments to reduce the impact of price fluctuations on electric fuel and purchased energy costs needed to meet its power supply requirements. Under PSCW rules, WP&L can also seek rate increases if it experiences an extraordinary increase in the cost of electric fuel and purchased energy costs or if the annual costs are more than 3% higher than the estimated costs used to establish rates. Such rules were revised effective for 2003 for WP&L and significantly reduce the regulatory lag for Wisconsin utilities and customers related to the timing of changes in rates for increased or decreased fuel and purchased energy costs. Based on these revised rules, WP&L does not anticipate any significant earnings exposure related to fuel and purchased energy costs.

WP&L periodically utilizes natural gas commodity derivative instruments to reduce the impact of price fluctuations on natural gas purchased and injected into storage during the summer months and withdrawn and sold at current market prices during the winter months. The natural gas commodity swaps in place approximate the forecasted storage withdrawal plan during this period. Therefore, market price fluctuations that result in an increase or decrease in the value of the physical commodity are substantially offset by changes in the value of the natural gas commodity swaps. A 10% increase (decrease) in the price of natural gas would not have a significant impact on the combined fair market value of the natural gas in storage and related swap arrangements in place at Dec. 31, 2003. To the extent actual storage withdrawals vary from forecasted withdrawals, WP&L has physical commoditygas price exposure. A 10 percent increase (decrease) in the price of gas would have an insignificant impact on the combined fair market value of the gas in storage and related swap arrangements in place as of December 31, 2000 and 1999. A-12 MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (CONTINUED) EQUITY PRICE RISK--WP

Equity Price Risk - WP&L maintains a trust fundsfund to fund its anticipated nuclear decommissioning costs. As of DecemberAt Dec. 31, 20002003 and 1999, these funds were2002, this fund was invested primarily in domestic equity and debt instruments. Fluctuations in equity prices or interest rates willdo not affect WP&L's&L’s consolidated results of operations as such fluctuations are recorded in equally offsetting amounts of investment income and depreciation expense when they are realized.operations. In February 2001, WP&L entered into a four-year hedge on equity assets in its nuclear decommissioning trust fund. In January 2004, WP&L liquidated all of its qualified decommissioning trust fund assets into money market funds as a result of the pending Kewaunee sale. Refer to Notes 1(l)10(c) and 15 of the “Notes to Consolidated Financial Statements” for further discussion.

Refer to Notes 1(j) and 10 of the "Notes“Notes to Consolidated Financial Statements"Statements” for further discussion of WP&L's&L’s derivative financial instruments. A-13

Accounting Pronouncements - In January 2003, the FASB issued FIN 46 which addresses consolidation by business enterprises of variable interest entities. FIN 46 requires consolidation where there is a controlling financial interest in a variable interest entity or where the variable interest entity does not have sufficient equity

at risk to finance its activities without additional subordinated financial support from other parties. WP&L adopted FIN 46, related to those entities that are considered to be special-purpose entities, on Dec. 31, 2003 with no material impact on its financial condition or results of operations. WP&L continues to evaluate tolling arrangements, renewable energy entities and any other non-special purpose entities, to determine if they require consolidation under the revised FIN 46 guidance issued by the FASB in December 2003. WP&L will apply the provisions of the revised guidance as of March 31, 2004.

WP&L adopted SFAS 143 on Jan. 1, 2003, which provides accounting and disclosure requirements for retirement obligations associated with long-lived assets (AROs). Refer to Note 16 of the “Notes to Consolidated Financial Statements” for additional information.

WP&L adopted SFAS 149 for contracts entered into or modified after June 30, 2003, except for certain implementation issues and certain provisions of forward purchase and sale contracts and for hedging relationships designated after June 30, 2003. Refer to Note 10(a) of the “Notes to Consolidated Financial Statements” for additional information.

In May 2003, the FASB issued SFAS 150, “Accounting for Certain Financial Instruments with Characteristics of Both Liabilities and Equity,” which requires an issuer to classify outstanding free-standing financial instruments within its scope as a liability on its balance sheet even though the instruments have characteristics of equity. WP&L adopted SFAS 150 on July 1, 2003 with no material impact on its financial condition or results of operations. WP&L continues to evaluate the implications of FSP No. FAS 150-3, “Effective Date, Disclosures, and Transition for Mandatorily Redeemable Financial Instruments of Certain Nonpublic Entities and Certain Mandatorily Redeemable Noncontrolling Interests under FASB Statement No. 150, Accounting for Certain Financial Instruments with Characteristics of Both Liabilities and Equity,” issued in November 2003, which defers the effective date for applying the provisions of SFAS 150 for certain mandatorily redeemable non-controlling interests.

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. As permitted by FSP No. FAS 106-1, “Accounting and Disclosure Requirements Related to the Medicare Prescription Drug, Improvement and Modernization Act of 2003,” WP&L has elected to defer reflecting the effect of the Act on postretirement net periodic benefit cost and the accumulated postretirement benefit obligation in the Consolidated Financial Statements, since specific authoritative guidance on the accounting for the federal subsidy is pending and that guidance, when issued, could require WP&L to change previously reported information. WP&L is currently evaluating the effect of the Act on its other postretirement benefits expense.

WP&L does not expect the various other new accounting pronouncements not mentioned above that were effective in 2003 to have a material impact on its results of operations or financial condition.

Critical Accounting Policies - Based on historical experience and various other factors, WP&L believes the policies identified below are critical to its business and the understanding of its results of operations as they require critical estimates be made based on the assumptions and judgment of management. The preparation of consolidated financial statements requires management to make various estimates and assumptions that affect revenues, expenses, assets, liabilities and the disclosure of contingencies. The results of these estimates and judgments form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates and judgments. WP&L’s management has discussed these critical accounting policies with the Audit Committee of its Board of Directors. Refer to Note 1 of the “Notes to Consolidated Financial Statements” for a discussion of WP&L’s accounting policies and the estimates and assumptions used in the preparation of the consolidated financial statements.

Regulatory Assets and Liabilities - WP&L is regulated by various federal and state regulatory agencies. As a result, it qualifies for the application of SFAS 71, which recognizes that the actions of a regulator can provide reasonable assurance of the existence of an asset or liability. Regulatory assets or liabilities arise as a result of a difference between GAAP and the accounting principles imposed by the regulatory agencies. Regulatory assets generally represent incurred costs that have been deferred as they are probable of recovery in customer rates. Regulatory liabilities generally represent obligations to make refunds to customers for various reasons.

WP&L recognizes regulatory assets and liabilities in accordance with the rulings of its federal and state regulators and future regulatory rulings may impact the carrying value and accounting treatment of WP&L’s regulatory assets and liabilities. WP&L periodically assesses whether the regulatory assets are probable of future recovery by considering factors such as regulatory environment changes, recent rate orders issued by the applicable regulatory agencies and the status of any pending or potential deregulation legislation. The assumptions and judgments used by regulatory authorities continue to have an impact on the recovery of costs, the rate of return on invested capital and the timing and amount of assets to be recovered by rates. A change in these assumptions may result in a material impact on WP&L’s results of operations. Refer to Note 1(c) of the “Notes to Consolidated Financial Statements” for further discussion.

Derivative Financial Instruments - WP&L uses derivative financial instruments to hedge exposures to fluctuations in certain commodity prices, volatility in a portion of natural gas sales volumes due to weather and to mitigate the equity price volatility associated with certain investments in equity securities. WP&L does not use such instruments for speculative purposes. To account for these derivative instruments in accordance with the applicable accounting rules, WP&L must determine the fair value of its derivatives. In accordance with SFAS 133, the fair value of all derivative instruments are recognized as either assets or liabilities in the balance sheet with the changes in their value generally recorded as regulatory assets or liabilities. If an established, quoted market exists for the underlying commodity of the derivative instrument, WP&L uses the quoted market price to value the derivative instrument. For other derivatives, WP&L estimates the value based upon other quoted prices or acceptable valuation methods. WP&L also reviews the nature of its contracts for the purchase and sale of non-financial assets to assess whether the contracts meet the definition of a derivative and the requirements to follow hedge accounting as allowed by the applicable accounting rules. The determination of derivative status and valuations involves considerable judgment.

SFAS 149 amends and clarifies accounting for derivative instruments, including certain derivative instruments embedded in other contracts, and for hedging activities under SFAS 133. Although SFAS 149 is expected to result in more energy contracts at WP&L qualifying as derivatives, changes in the fair value of these derivatives are generally reported as changes in regulatory assets and liabilities rather than being reported currently in earnings, based on the regulatory treatment. Additionally, WP&L has some commodity purchase and sales contracts that have been designated, and qualify for, the normal purchase and sale exception. Based on this designation, these contracts are not accounted for as derivative instruments.

A number of WP&L’s derivative transactions are based on the fuel and natural gas cost recovery mechanisms in place, as well as other specific regulatory authorizations. As a result, changes in fair market values of such derivatives generally have no impact on WP&L’s results of operations.

Unbilled Revenues - Energy sales to individual customers are based on the reading of their meters, which occurs on a systematic basis throughout the month. At the end of each month, amounts of energy delivered to customers since the date of the last meter reading are estimated and the corresponding estimated unbilled revenue is recorded. The unbilled revenue estimate is based on daily system demand volumes, estimated customer usage by class, weather impacts, line losses and the most recent customer rates. Such process involves the use of various estimates, thus significant changes in the estimates could have a material impact on WP&L’s results of operations.

Accounting for Pensions and Other Postretirement Benefits - WP&L accounts for pensions and other postretirement benefits under SFAS 87, “Employers’ Accounting for Pensions” and SFAS 106, “Employers’ Accounting for Postretirement Benefits Other Than Pensions,” respectively. Under these rules, certain assumptions are made which represent significant estimates. There are many factors involved in determining an entity’s pension and other postretirement liabilities and costs each period including assumptions regarding employee demographics (including age, life expectancies, and compensation levels), discount rates, assumed rate of returns and funding. Changes made to the plan provisions may also impact current and future pension and other postretirement costs. WP&L’s assumptions are supported by historical data and reasonable projections and are reviewed annually with an outside actuary firm and an investment consulting firm. As of Dec. 31, 2003, WP&L was using a 6% discount rate to calculate benefit obligations and a 9% annual rate of return on investments. In selecting an assumed discount rate, WP&L reviews various corporate Aa bond indices. The 9% annual rate of return is consistent with WP&L’s historical returns and is based on projected long-term equity and bond returns, maturities and asset allocations. Refer to Note 6 of the “Notes to Consolidated Financial Statements” for discussion of the impact of a change in the medical trend rates.

The accompanying Notes to Consolidated Financial Statements are an integral part of these statements.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS ARE AN INTEGRAL PART OF THESE STATEMENTS. A-20 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (A) GENERAL--The

(a) General- The consolidated financial statements include the accounts of WP&L and its principal consolidated subsidiaries.subsidiaries WPL Transco LLC and South Beloit. WP&L is a direct subsidiary of Alliant Energy and is engaged principally in the generation, transmission, distribution and sale of electric energy; the purchase, distribution, transportation and sale of natural gas; and the provision of water services.and various other energy-related services including construction management services for wind farms. Nearly all of WP&L's&L’s retail customers are located in south and central Wisconsin. WP&L's principal

The consolidated financial statements reflect investments in controlled subsidiaries are WPL Transco LLCon a consolidated basis. FIN 46, issued by the FASB in January 2003, requires consolidation where there is a controlling financial interest in a variable interest entity or where the variable interest entity does not have sufficient equity risk to finance its activities without additional subordinated financial support from other parties. All significant intercompany balances and South Beloit.transactions have been eliminated from the consolidated financial statements. The consolidated financial statements are prepared in conformity with accounting principles generally accepted in the U.S.,GAAP, which give recognition to the rate making and accounting practices of FERC and state commissions having regulatory jurisdiction. The preparation of the consolidated financial statements requires management to make estimates and assumptions that affect: a) the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements; and b) the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Certain prior period amounts have been reclassified on a basis consistent with the current year presentation. The most significant reclassifications relate to the reporting of accumulated costs of removal which are non-legal retirement obligations and accumulated decommissioning costs accrued prior to January 1, 2003. Previously, these costs were included as components of “Accumulated Depreciation” but in accordance with recent SEC guidance are now shown in “Cost of removal obligations” on the Consolidated Balance Sheet at Dec. 31, 2002.

Unconsolidated investments for which WP&L has at least a 20 percent non-controllingdoes not control, but does have the ability to exercise significant influence over operating and financial policies (generally, 20% to 50% voting interestinterest), are generally accounted for under the equity method of accounting. These investments are stated at acquisition cost, increased or decreased for WP&L's&L’s equity in net income or loss, which is included in "Miscellaneous, net"“Equity income from unconsolidated investments” in the Consolidated Statements of Income and decreased for any dividends received. Investments that do not meet the criteria for consolidation or the equity method of accounting are accounted for under the cost method. (B) REGULATION--WP

(b) Regulation - WP&L is a public utility company subject to regulation byunder PUHCA, FERC, the PSCW and the ICC. (C) REGULATORY ASSETS--WP

(c) Regulatory Assets and Liabilities - WP&L is subject to the provisions of SFAS 71, "Accounting for the Effects of Certain Types of Regulation," which provides that rate-regulated public utilities record certain costs and credits allowed in the rate making process in different periods than for non-regulated entities. These are deferred as regulatory assets or accrued as regulatory liabilities and are recognized in the Consolidated Statements of Income at the time they are reflected in rates. At DecemberAs of Dec. 31, 20002003 and 1999,2002, WP&L had $7 million and $6 million, respectively, of regulatory assets of $92.4 millionthat were not earning returns. At Dec. 31, 2003 and $85.9 million, respectively,2002, regulatory assets and liabilities were comprised of the following items (in millions):
2000 1999 -------- -------- Tax-related (Note 1(d))..................................... $37.6 $43.4 Energy efficiency program costs............................. 19.8 7.0 Environmental liabilities (Note 11(e))...................... 16.6 19.1 Other....................................................... 18.4 16.4 ----- ----- $92.4 $85.9 ===== =====

WP&L believes it is probable that any differences between expenses for legal AROs calculated under SFAS 143 and expenses recovered currently in rates will be recoverable in future rates, and is deferring the difference of $8.3 million as a regulatory asset. WP&L also collects in rates future removal costs for many assets that do not have an associated legal ARO. WP&L records a liability for the estimated amounts it has collected in rates for these future removal costs less amounts spent on removal activities. At Dec. 31, 2003 and 2002, non-legal removal obligations of $209.9 million and $199.1 million were recorded in “Regulatory liabilities” and “Cost of removal obligations,” respectively, on the Consolidated Balance Sheets.

If a portion of WP&L's&L’s operations becomes no longer subject to the provisions of SFAS 71 as a result of competitive restructuring or otherwise, a write-down of related regulatory assets would be required, unless some form of transition cost recovery is established by the appropriate regulatory body that would meet the requirements under generally accepted accounting principlesGAAP for continued accounting as regulatory assets during such recovery period. In addition, WP&L would be required to determine any impairment of other assets and write-down such assets to their fair value.

(d) Income Taxes - WP&L is subject to the provisions of SFAS 109 and follows the liability method of accounting for deferred income taxes, which requires the establishment of deferred tax assets and liabilities, as appropriate, for all temporary differences between the tax basis of assets and liabilities and the amounts reported in the consolidated financial statements. Deferred taxes are recorded using currently enacted tax rates.

Except as noted below, income tax expense includes provisions for deferred taxes to reflect the tax effects of temporary differences between the time when certain costs are recorded in the accounts and when they are deducted for tax return purposes. As temporary differences reverse, the related accumulated deferred income taxes are reversed to income. Investment tax credits have been deferred and are subsequently credited to income over the average lives of the related property. Other tax credits reduce income tax expense in the year claimed and are generally related to research and development.

The PSCW has allowed rate recovery of deferred taxes on all temporary differences since August 1991. WP&L established a regulatory asset associated with those temporary differences occurring prior to August 1991 that will be recovered in future rates. Alliant Energy files a consolidated federal income tax return. Under the terms of an agreement between Alliant Energy and WP&L, WP&L calculates its federal income tax provisions and makes payments to or receives payments from Alliant Energy as if it were a separate taxable entity. (E) TEMPORARY CASH INVESTMENTS--Temporaryrates through 2007.

(e) Temporary Cash Investments - Temporary cash investments are stated at cost, which approximates market value, and are considered cash equivalents for the Consolidated Balance Sheets and the Consolidated Statements of Cash Flows. These investments consist of short-term liquid investments that have maturities of less than 90 days fromdays.

(f) Property, Plant and Equipment - Utility plant is recorded at original cost, which includes overhead, administrative costs and AFUDC. WP&L’s aggregate AFUDC recovery rates for 2003, 2002 and 2001, computed in accordance with the date of acquisition. (F) DEPRECIATION OF UTILITY PROPERTY, PLANT AND EQUIPMENT--WPprescribed regulatory formula, were 9.5%, 2.6% and 7.9%, respectively.

WP&L uses thea combination of remaining life, straight-line and sum-of-the-years-digits depreciation methodmethods as approved by the PSCW and the ICC. The remaining depreciable life of Kewaunee, of which WP&L is a co-owner, is based on the PSCW approved revised end-of-life of 2010. Depreciation expense related to the decommissioning of Kewaunee is discussed in Note 11(f). The average rates of depreciation for electric and gas properties, of WP&L, consistent with current rate making practices, were as follows:
2000 1999 1998 -------- -------- -------- Electric.................................................... 3.6% 3.6% 3.6% Gas......................................................... 4.1% 3.9% 3.8%

This accumulated amortization assumes spent nuclear fuel will have no residual value. Estimated future disposal costs and AFUDC. WP&L's aggregate gross AFUDC recovery rates used for 2000, 1999 and 1998, computed in accordance with the prescribed regulatory formula, were 10.8%, 5.4% and 5.2%, respectively. of such fuel are expensed based on KWhs generated.

Other property, plant and equipment is recorded at original cost.cost, the majority of which is depreciated using the straight-line method. Upon retirement or sale of other property and equipment, the cost and related accumulated depreciation are removed from the accounts and any gain or loss is included in "Miscellaneous, net" in the Consolidated Statements of Income. Ordinary retirements of utility plant including removal costs lessand salvage value are netted and charged to accumulated depreciation upon removal from utility plant accounts and no gain or loss is recognized. (H) OPERATING REVENUES--WPRemoval costs reduce the regulatory liability previously established.

(g) Operating Revenues - Revenues from WP&L are primarily from electric and natural gas sales and deliveries and are recorded under the accrual method of accounting and recognized upon delivery. WP&L accrues revenues for services rendered but unbilled at month-end. In 2000, WP&L recorded an increaseserves as a collection agent for sales or various other taxes and record revenues on a net basis. The revenues do not include the collection of $10 million in the estimate of utility services rendered but unbilled at month-end due to the implementation of a refined estimation process. A-22 (1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) (I) UTILITY FUEL COST RECOVERY--WP&L'saforementioned taxes.

(h) Utility Fuel Cost Recovery - WP&L’s retail electric rates are based in part on annual forecasted fuel and purchased-power costs. Under PSCW rules, WP&L can seek emergency rate increases if it experiences an extraordinary increase in these costs or if the annual costs are more than 3 percent3% higher than the estimated costs used to establish rates. WP&L has a gas performance incentive which includes a sharing mechanism whereby 40 percent50% of all gains and losses relative to current commodity prices, as well as other benchmarks, are retained by WP&L, with the remainder refunded to or recovered from customers. (J) NUCLEAR REFUELING OUTAGE COSTS--Operating

(i) Generating Facility Outages - Operating expenses incurred during refueling outages at Kewaunee and the maintenance costs incurred during outages for WP&L’s various other generating facilities are expensed by WP&L as incurred. The next scheduledtiming of the Kewaunee refueling outage at Kewaunee isoutages during 2001-2003 and anticipated to commence in Fall 2001. (K) NUCLEAR FUEL--Nuclear fuelrefueling outages for Kewaunee is recorded at its original cost and is amortized to expense based upon the quantity of heat produced for the generation of electricity. This accumulated amortization assumes spent nuclear fuel will have no residual value. Estimated future disposal costs of such fuel2004-2006 are expensed based on kilowatt-hours generated.

(j) Derivative Financial Instruments - WP&L uses derivative financial instruments to hedge exposures to fluctuations in interest rates, certain commodity prices and volatility in a portion of natural gas sales volumes due to weather. WP&L also utilizes derivatives to mitigate the equity price volatility associated with certain investments in equity securities. WP&L does not use such instruments for speculative purposes. In accordance with SFAS 133, "Accounting for Derivative Instruments and Hedging Activities," as amended by SFAS 138, "Accounting for Certain Derivative Instruments and Certain Hedging Activities--an Amendment of SFAS 133," theThe fair value of all derivatives are recorded as assets or liabilities on the Consolidated Balance Sheets and gains and losses related to derivatives that are designated as, and qualify as hedges, are recognized in earnings when the underlying hedged item or physical transaction is recognized in income. Gains and losses related to derivatives that do not qualify for, or are not designated in hedge relationships, are recognized in earnings immediately. Based on the fuel and natural gas cost recovery mechanisms in place, as well as other specific regulatory authorizations, changes in fair market values of WP&L’s derivatives generally have no impact on its results of operations. WP&L has a number ofsome commodity purchase and sales contracts for both capacity and energy that have been designated, and qualify for, the normal purchase and sale exception in SFAS 138. Basedand based on this designation, these contracts are not accounted for as derivative instruments.

WP&L is exposed to losses related to financial instruments in the event of counterparties’ non-performance. WP&L has established controls to determine and monitor the creditworthiness of counterparties in order to mitigate its exposure to counterparty credit risk. WP&L is not aware of any material exposure to counterparty credit risk related to its derivative financial instruments. Refer to Note 10 for further discussion of WP&L's&L’s derivative financial instruments. (2) MERGER In April 1998, WPLH, IES

(k) Pension Plan - For the defined benefit pension plan sponsored by Corporate Services, Alliant Energy allocates pension costs and IPC completed a merger resultingcontributions to WP&L based on labor costs of plan participants and any additional minimum pension liability based on the funded status of the WP&L group.

(l) Asset Valuations - Long-lived assets, excluding regulatory assets, are reviewed for possible impairment whenever events or changes in Alliant Energy.circumstances indicate the carrying value of the assets may not be recoverable.

Impairment is indicated if the carrying value of an asset exceeds its undiscounted future cash flows. An impairment charge is recognized equal to the amount the carrying value exceeds the asset’s fair value. The merger wasfair value is determined by the use of quoted market prices, appraisals, or the use of other valuation techniques such as expected discounted future cash flows. The estimated fair value, less cost to sell assets held for sale, is compared each reporting period to their carrying values. Impairment charges are recorded for assets held for sale if the carrying value of such asset exceeds the estimated fair value less cost to sell.

If events or circumstances indicate the carrying value of investments accounted for under the equity method of accounting may not be recoverable, potential impairment is assessed by comparing the future anticipated cash flows from these investments to their carrying values. If an impairment is indicated, a charge is recognized equal to the amount the carrying value exceeds the investment’s fair value.

(2) UTILITY RATE MATTERS

In February 2004, WP&L received approval from the PSCW to refund $5.3 million to its natural gas customers as relates to its annual performance under the gas performance incentive. The PSCW has not yet audited the refund calculation, but agreed with WP&L’s request to refund approximately 80% of the total refund amount at this time. This refund was completed in February 2004 and the remainder of the refund will be completed after the PSCW completes their audit and issues a poolingruling. At Dec. 31, 2003, WP&L had reserves for all amounts related to these refunds. Refer to Note 1(h) for further discussion of interests. A-23 WP&L’s fuel cost recovery.

(3) LEASES

WP&L's&L’s operating lease rental expenses, which include certain purchased-power agreements, for 2000, 19992003, 2002 and 19982001 were $7.9$25.9 million, $7.7$24.5 million and $6.4$23.4 million, respectively. The purchased-power agreements total below includes $464 million and $69 million related to the Riverside and RockGen plants, respectively, in Wisconsin. Riverside is expected to be placed in service in 2004. WP&L's&L continues to evaluate Riverside, RockGen and other tolling arrangements, renewable energy entities and any other non-special purpose entities, to determine if they require consolidation under the revised FIN 46 guidance issued by the FASB in December 2003. WP&L will apply the provisions of the revised guidance as of March 31, 2004. The synthetic leases relate to the financing of utility railcars and a utility radio dispatch system. These leases do not meet the consolidation requirements per FIN 46 and were not included on the Consolidated Balance Sheets. WP&L has guaranteed the residual value of its synthetic leases totaling $13 million in the aggregate. The guarantees extend through the maturity of each respective underlying lease with remaining terms up to 12 years. Residual value guarantees have been included in the future minimum lease payments by year are as followsnoted in the following table (in millions):

(4) UTILITYSALE OF ACCOUNTS RECEIVABLE

Utility customer accounts receivable, including unbilled revenues, arise primarily from the sale of electricityelectric and natural gas.gas sales. At DecemberDec. 31, 20002003 and 1999,2002, WP&L was serving a diversified base of residential, commercial and industrial customers and did not have any significant concentrations of credit risk. An

WP&L participates in a combined utility customer accounts receivable financing arrangement exists through 2001 forsale program whereby WP&L in which itand IP&L may sell up to a combined maximum amount of $150$250 million (there are no individual subsidiary limits) of their respective accounts receivable to a third-party financial institution on a limited recourse basis. Accounts receivable sold include receivables arising from sales to customersbasis through wholly-owned and to other public, municipalconsolidated special purpose entities. Corporate Services acts as a collection agent for the buyer and cooperative utilities, as well as from billings to the co-owners of the jointly-owned electric generating plants operated by WP&L. WP&L receives a fee for billingcollection services. The agreement expires in April 2006 and collection functions, whichis subject to annual renewal or renegotiation for a longer period thereafter. Under terms of the agreement, the third-party financial institution

purchases the receivables initially for the face amount. On a monthly basis, this sales price is adjusted, resulting in payments to the third-party financial institution of an amount that varies based on interest rates and length of time the sold receivables remain outstanding. Collections on sold receivables are used to purchase additional receivables from WP&L's responsibility, that approximates fair value.&L and IP&L.

At Dec. 31, 2003 and 2002, WP&L had sold $50 million and $116 million of receivables, respectively. In 2000, 19992003, 2002 and 1998,2001, WP&L received approximately $0.9$0.8 billion, $0.9$1.2 billion and $1.0$1.1 billion, respectively, in aggregate proceeds from this facility.the sale of accounts receivable. WP&L uses proceeds from the sale of accounts receivable and unbilled revenues to maintain flexibility in its capital structure, take advantage of favorable short-term rates and finance a portion of its long-term cash needs. Included in WP&L's Consolidated Statements of Income for 2000, 1999 and 1998, were&L paid fees associated with these sales of $5.0$1.2 million, $2.2 million and $4.0 million in 2003, 2002 and $4.9 million,2001, respectively.

WP&L accounts for the sale of accounts receivable to the third-party financial institution as sales under SFAS 140, “Accounting for Transfers and Servicing of Financial Assets and Extinguishments of Liabilities,” which do not require consolidation per the guidelines of FIN 46. Retained receivables are available to the third-party financial institution to pay any fees or expenses due it, and to absorb all credit losses incurred on any of the sold receivables.

Alliant Energy files a consolidated federal income tax return. Under the terms of an agreement between Alliant Energy and its subsidiaries, including WP&L, the subsidiaries calculate their respective federal income tax provisions and make payments to or receive payments from Alliant Energy as if they were separate taxable entities. Separate return amounts are adjusted to reflect state apportionment benefits net of federal tax and the fact that PUHCA prohibits the retention of tax benefits at the parent level. Any difference between the separate return methodology and the actual consolidated return is allocated as prescribed in Alliant Energy’s tax allocation agreement. WP&L realized net benefits of $2.9 million, $0 and $0 related to state apportionment and allocation of parent tax benefits in 2003, 2002 and 2001, respectively.

Substantially all of WP&L has two&L’s employees are covered by several non-contributory defined benefit pension plans that cover substantially all of its employees.plans. Benefits are based on the employees'employees’ years of service and compensation. WP&L also provides certain postretirement health care and life benefits to eligible retirees. In general, the health care plans are contributory with participants'participants’ contributions adjusted annuallyregularly and the life insurance plans are non-contributory.

WP&L’s net periodic benefit cost is primarily included in “Other operation and $36.5maintenance” in the Consolidated Statements of Income. WP&L calculates the fair value of plan assets by using the straight market value of assets approach.

Postretirement benefit plans are funded via specific assets within certain retirement plans (401(h) assets) as well as a VEBA trust. The asset allocation of the 401(h) assets mirror the qualified pension plan assets and the asset allocation of the VEBA trust are reflected in the following table under “Other Postretirement Plans.” The asset allocation for WP&L’s qualified pension and other postretirement benefit plans at Sept. 30, 2003 and 2002, and the qualified pension plan target allocation for 2003 were as follows:

WP&L’s plan assets are managed by outside investment managers. WP&L’s investment strategy and its policies employed with respect to pension and postretirement assets is to combine both preservation of principal, and prudent and reasonable risk-taking to protect the integrity of the assets in meeting the obligations to the participants while achieving the optimal return possible over the long-term. It is recognized that risk and volatility are present to some degree with all types of investments; however, high levels of risk are minimized at the total fund level. This is accomplished through diversification by asset class, number of investments, and sector and industry limits when applicable.

For the pension plans, the mix among asset classes is controlled by long-term asset allocation targets. The assets are viewed as long-term with moderate liquidity needs. Historical performance results and future expectations suggest that equity securities will provide higher total investment returns than debt securities over a long-term investment horizon. Consistent with the goals to maximize returns and minimize risk over the long-term, the pension plans have a long-term investment posture more heavily weighted towards equity holdings. The asset allocation mix is monitored quarterly and appropriate action is taken as needed to rebalance the assets within the prescribed range. Assets related to postretirement plans are viewed as long-term. A balanced mix of both equity and debt securities are utilized to maximize returns and minimize risk over the long-term.

Prohibited investment vehicles related to the pension and postretirement plans include, but may not be limited to, direct ownership of real estate, real estate investment trusts, private placements, unregistered or restricted stock, options and futures unless specifically approved, margin trading, oil and gas limited partnerships, commodities, short selling, commercial mortgage obligations and securities of the managers’ firms or affiliate firms.

WP&L estimates that funding for the qualified pension and postretirement benefit plans for 2004 will be $0 and approximately $4 million, respectively.

In December 2003, the President signed into law the Medicare Prescription Drug, Improvement and $8.4 million, respectively,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 September 30, 1999. retiree health care benefit plans, that provide a benefit that is at least

actuarially equivalent to Medicare Part D. As permitted by FSP No. FAS 106-1, “Accounting and Disclosure Requirements Related to the Medicare Prescription Drug, Improvement and Modernization Act of 2003,” WP&L has elected to defer reflecting the effect of the Act on postretirement net periodic benefit cost and the accumulated postretirement benefit obligation in the Consolidated Financial Statements, since specific authoritative guidance on the accounting for the federal subsidy is pending and that guidance, when issued, could require WP&L to change previously reported information. WP&L is currently evaluating the effect of the Act on its other postretirement benefits expense.

Alliant Energy sponsors several non-qualified pension plans that cover certain current and former officers.key employees. The pension expense allocated to WP&L for these plans was $1.2$1.7 million, $0.8$1.5 million and $0.8$1.0 million in 2000, 19992003, 2002 and 1998,2001, respectively. WP&L has various life insurance policies that cover certain key employees and directors. At Dec. 31, 2003 and 2002, the cash surrender value of these investments was $11 million and $10 million, respectively. A significant number of WP&L employees also participate in defined contribution pension plans (401(k) plans). WP&L's&L’s contributions to the plans, which are based on the participants'participants’ level of contribution, were $2.1 million, $2.0$2.2 million and $2.4$2.1 million in 2000, 19992003, 2002 and 1998,2001, respectively.

(9) INVESTMENTS AND ESTIMATED FAIR VALUE OF FINANCIAL INSTRUMENTS

The carrying amount of WP&L's&L’s current assets and current liabilities approximates fair value because of the short maturity of such financial instruments. Since WP&L is subject to regulation, any gains or losses related to the difference between the carrying amount and the fair value of its financial instruments may not be realized by WP&L's parent.Alliant Energy.

(10) DERIVATIVE FINANCIAL INSTRUMENTS (A) ACCOUNTING FOR DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES--WP

(a) Accounting for Derivative Instruments and Hedging Activities - WP&L adopted SFAS 133 as of July 1, 2000. SFAS 133 requires that everyrecords derivative instrument be recordedinstruments at fair value on the balance sheet as an assetassets or liability measured at its fair valueliabilities and that changes in the derivative'sderivatives’ fair value be recognized currentlyvalues are generally recorded as regulatory assets or liabilities. At Dec. 31, 2003 and 2002, WP&L had $1.3 million and $2.7 million of derivative assets included in earnings unless specific hedge“Other current assets” and $3.6 million and $7.1 million of derivative liabilities included in “Other current liabilities” on its Consolidated Balance Sheets, respectively.

In April 2003, the FASB issued SFAS 149, which amends and clarifies accounting criteria are met.for derivative instruments, including certain derivative instruments embedded in other contracts, and for hedging activities under SFAS 133 requires that133. Although SFAS 149 is expected to result in more energy contracts at WP&L qualifying as of the date of initial adoption, the difference betweenderivatives, changes in the fair value of derivative instruments recorded on the balance sheet and the previous carrying amount of thosethese derivatives beare generally reported as changes in net income or other comprehensive income, as appropriate, as the cumulative effect of a change in accounting principle in accordance with APB 20, "Accounting Changes." Transition adjustments relating to WP&L's derivative instruments had no material impact on net income or the balance sheet. A limited number of WP&L's fixed price commodity contracts are defined as derivatives under SFAS 133. The fair values of these derivative instruments have been recorded asregulatory assets and liabilities rather than being reported currently in earnings, based on the balance sheet and in the transition adjustment in accordance with the transition provisions of SFAS 133. Changes in the fair values of these instruments subsequent to July 1, 2000, to the extent that the derivatives are designated in cash flow hedging relationships and are effective at mitigating the underlying commodity risk, are recorded in other comprehensive income. At the date the underlying transaction occurs, the amounts accumulated in other comprehensive income are reported in the Consolidated Statements of Income. To the extent that the hedges are not effective, the ineffective portion of the changes in fair value is recorded directly in earnings. As of December 31, 2000,regulatory treatment.

Cash Flow Hedging Instruments - During 2003 and/or 2002, WP&L held various derivative instruments designated as cash flow hedging instruments and other derivatives. The cash flow hedging instruments are comprised ofinstruments. WP&L utilized natural gas swaps and coal purchase and sales contracts which are used to manage the price of anticipated coal purchases and sales. WP&L utilizes gas commodity financial swap arrangements to reduce the impact of price fluctuations on natural gas purchased and injected into storage during the summer months and withdrawn and sold at current market prices during the winter months pursuant to the natural gas cost incentive sharing mechanism with customers in Wisconsin. The gas commodity swaps in place hedgeWP&L also utilized physical coal purchase contracts, some of which did not qualify for the forecasted salesnormal purchase and sale exception, to manage the price of natural gas withdrawn from storage during this period. anticipated coal purchases and sales.

In 2000,2003 and 2002, $0 and a net gainloss of approximately $0.4$0.2 million, wasrespectively, were recognized in earnings (recorded in gas revenues) representingrelating to the amount of hedge ineffectiveness.ineffectiveness in accordance with SFAS 133. In 2003 and 2002, WP&L did not exclude any components of the derivative instruments'instruments’ gain or loss from the assessment of hedge effectiveness and there werewas no reclasses into earnings impact as a result of the discontinuance of hedges. As of DecemberAt Dec. 31, 2000, the maximum length of time over which2003, WP&L isdid not have any cash flow hedging its exposure to the variabilityinstruments outstanding.

Other Derivatives Not Designated in future cash flows for forecasted transactions is ten months andHedge Relationships - WP&L estimates that losses of $4.7 million will be reclassified from accumulated other comprehensive income into earnings within the 12 months between January 1, 2001 and December 31, 2001 as the hedged transactions affect earnings. WP&L's&L’s derivatives that havewere not been designated in hedge relationships include naturalduring 2003 and/or 2002 included coal and gas swapscontracts. Coal and electricitygas contracts that do not qualify for the normal purchase and sale exception were used to manage the price collars which manage energy costs during supply/demand imbalances. As of December 31, 2000, these derivatives were recorded at their fair value as derivative assetsanticipated coal and derivative liabilities on the Consolidated Balance Sheetsgas purchases and purchased-power expense in the Consolidated Statements of Income. A-30 (10) DERIVATIVE FINANCIAL INSTRUMENTS (CONTINUED) (B) WEATHER DERIVATIVES--WPsales.

(b) Weather Derivatives - WP&L uses weather derivatives to reduce the impact of weather volatility on its natural gas sales volumes. EITF 99-2, "AccountingIn 2003 and 2002, Corporate Services, as agent for Weather Derivatives," requiresWP&L, entered into non-exchange traded options based on heating degree days in which Corporate Services receives payment from the use ofcounterparty if actual heating degree days are less than the strike price in the contract. Corporate Services paid premiums to enter into these contracts, which are amortized to expense over the contract period. WP&L has used the intrinsic value method to account for non-exchange tradedthese weather derivatives. In August 2000,

(c) Nuclear Decommissioning Trust Fund Investments - Historically, WP&L has entered into a non-exchange traded weather floor with a contract period from November 1, 2000 to March 31, 2001 that requires the counterparty pay WP&L $11,000 per heating degree-day less than 5,600 during the contract period. The maximum payout amount by the counterparty on this floor is $7 million. WP&L paid a premium to enter into this contract, which is being amortized to expense over the contract period. In August 1999, WP&L entered into a non-exchange traded "weather collar" with a contract period from November 1, 1999 to March 31, 2000. The maximum payout amount was $5 million. (C) NUCLEAR DECOMMISSIONING TRUST FUND INVESTMENTS--WP&L previously entered into an equity collar that used writtencombinations of options to mitigate the effect of significant market fluctuations on its common stock investments in its nuclear decommissioning trust funds. The program wasderivative transactions are designed to protect the portfolio'sportfolio’s value while allowing the funds to earn a total return modestly in excess of long-term expectations over the two-year hedge period, which was settled in December 2000. The notional amount of the options was $78 million at December 31, 1999. The options were reported at fair market value each reporting period. TheseIn 2003, fair value changes of these instruments did not impact net income as they were recorded as equally offsetting changes in the investment in nuclear decommissioning trust funds and accumulated depreciation. The option liability fair value exceeded the premium received by $17.8 million at December 31, 1999,regulatory liabilities or, for AROs, as reported by the trustee. an offset to regulatory assets (in 2002 as an offset to cost of removal obligations).

MGP SITES--WPSites - WP&L has current or previous ownership interests in 14 sites, previously associated with the production of gas for which it may be liable for investigation, remediation and monitoring costs relating to the sites. WP&L has received letters from state environmental agencies requiring no further action at foursix sites.

WP&L is 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.

WP&L records environmental liabilities based upon periodic studies, most recently updated in the third quarter of 2000,2003, related to the MGP sites. 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. 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 made and are adjusted as further information develops or circumstances change. Costs of future A-32 (11) COMMITMENTS AND CONTINGENCIES (CONTINUED) expenditures for environmental remediation obligations are not discounted to their fair value. Management currently estimates the range of remaining costs to be incurred for the investigation, remediation and monitoring of all WP&L's&L’s sites to be approximately $4$5 million to $5$7 million.

Under the current rate making treatment approved by the PSCW, the MGP expenditures of WP&L, net of any insurance proceeds, are deferred and collected from gas customers over a five-yearfour-year period after neweffective with rates are implemented.set to recover such amounts. Regulatory assets have been recorded by WP&L, which reflect the probable future rate recovery, where applicable. Considering the current rate treatment, and assuming no material change therein, WP&L believes that the clean-up costs incurred for these MGP sites will not have a material adverse effect on its financial condition or results of operations. Settlement has been reached with all of WP&L's&L’s insurance carriers regarding reimbursement for its MGP-related costs and all issues have been resolved. Insurance recoveries available as of both December 31, 2000 and 1999 for WP&L were $2.1 million. Pursuant to its applicable rate making treatment, WP&L has recorded its recoveries as an offset against its regulatory assets. NATIONAL ENERGY POLICY ACT OF 1992--NEPAcosts.

NEPA - NEPA requires owners of nuclear power plants to pay a special assessment into a "Uranium“Uranium Enrichment Decontamination and Decommissioning Fund." The assessment is based upon uranium enrichment services provided in conjunction with prior nuclear fuel purchases. WP&L recovers theelected to pay its assessment in 15 annual installments. The costs associated with this assessment over the period the costs are assessed.for WP&L is being recovered through fuel costs. The final installment payment is scheduled to be made in fall 2006. WP&L continues to pursue relief from this assessment through litigation.

(15) PENDING SALE OF WP&L’S INTEREST IN KEWAUNEE

WP&L has signed a definitive agreement to sell its 41% ownership interest in Kewaunee to Richmond, Va.-based Dominion Energy Kewaunee, Inc. (Dominion), a subsidiary of Dominion Resources, Inc. Joint owner of Kewaunee, WPSC, also agreed to sell its 59% ownership interest in Kewaunee to Dominion. Pending various regulatory approvals, including the PSCW and NRC, the transaction is expected to be completed by fall 2004. WP&L anticipates that, based on an expected Nov. 1, 2004 closing date, 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 $67.3 million on Dec. 31, 2003. 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. Dominion will assume responsibility for the eventual decommissioning of Kewaunee and WP&L is required to provide qualified decommissioning trust assets of at least $160.7 million on an after-tax basis. The after-tax value of the qualified fund was $166.3 million on Dec. 31, 2003. In January 2004, WP&L liquidated all of the qualified decommissioning assets into money market funds as a result of the pending Kewaunee sale. 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 the plant’s current operating license will expire.

(16) ASSET RETIREMENT OBLIGATIONS

WP&L adopted SFAS 143 on Jan. 1, 2003, which provides accounting and disclosure requirements for AROs associated with long-lived assets. SFAS 143 requires that when an asset is placed in service the present value of retirement costs for which WP&L has a legal obligation must be recorded as liabilities with an equivalent amount added to the asset cost. The liability is accreted to its present value each period and the capitalized cost is depreciated over the useful life of the related asset. Upon settlement of the liability, an entity settles the obligation for its recorded amount or incurs a gain or loss.

The scope of SFAS 143 as it relates to WP&L primarily includes decommissioning costs for Kewaunee. The differences between the estimated decommissioning costs disclosed in Note 11(f) and the recorded SFAS 143 liability are primarily related to fuel management costs, non-nuclear demolition costs and the timing of future cash flows. It also applies to a smaller extent to several other assets including, but not limited to, active ash landfills, water intake facilities, underground storage tanks, groundwater wells, distribution equipment, easements, leases and the dismantlement of certain hydro facilities. Other than Kewaunee, WP&L’s current AROs are not significant. A reconciliation of the changes in WP&L’s AROs is depicted below (in millions):

  $175

Accretion expense

Balance at Dec. 31, 2003

If SFAS 143 had been adopted as of Jan. 1, 2001, WP&L would have recorded ARO SFAS 143 liabilities of $175 million at Dec. 31, 2002 and $161 million at Dec. 31, 2001. Refer to Note 15 for information regarding the pending sale of WP&L’s interest in Kewaunee.

At Dec. 31, 2002, prior to the adoption of SFAS 143, WP&L recorded $163.2 million of legal AROs in “Cost of removal obligations” on the Consolidated Balance Sheet.

(17) RELATED PARTY ISSUES In association with the 1998 merger that resulted in the formation of Alliant Energy, IESU, PARTIES

WP&L and IPCIP&L have entered into a System Coordination and Operating Agreement which became effective with the merger.Agreement. The agreement, which has been approved by FERC, provides a contractual basis for coordinated planning, construction, operation and maintenance of the interconnected electric generation and transmission (IP&L only) systems of the three utility companies.WP&L and IP&L. In addition, the agreement allows the interconnected system to be operated as a single entity with off-system capacity sales and purchases made to market excess system capability or to meet system capability deficiencies.
