Furnish particulars as to any significant contingent assets or liabilities existing at the end of the year. Notes relating to financial statements shown elsewhere in this report may be indicated here by reference. ---------------------------------------------------------------------------------------------------------------------------------- 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: (a) General: Alliant Energy Corporation (Alliant Energy), a Wisconsin corporation and registered holding company under the Public Utility Holding Company Act of 1935 (PUHCA), was created in the April 1998 merger of WPL Holdings, Inc., IES Industries Inc. and Interstate Power Company. Alliant Energy Corporate Services, Inc. (the Company) is a wholly-owned subsidiary of Alliant Energy and is the service company for the Alliant Energy system providing associate companies with a variety of administrative, management and support services. The primary operating companies of the system are IES Utilities Inc. (IESU), Wisconsin Power and Light Company (WP&L), Interstate Power Company (IPC) and Alliant Energy Resources, Inc. (AER). AER also has numerous subsidiaries who procure services from the Company. (b) Income Taxes: Deferred income taxes have been recorded by the Company 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 purposes. 2. NOTES PAYABLE TO ASSOCIATE COMPANIES: Alliant Energy has established utility and non-utility money pools to coordinate short-term borrowings for certain subsidiaries. The money pools provide a more efficient use of cash resources of the system and reduce outside short-term borrowings. The money pools are administered by the Company and funded, as needed, through the issuance of commercial paper by Alliant Energy. Interest expense and other fees are allocated based on borrowing amounts. The Public Service Commission of Wisconsin has restricted WP&L from lending money to non-utility affiliates and non-Wisconsin utilities. As a result, WP&L is prohibited from lending money to the utility money pool but is able to borrow money from the utility money pool. 20 3. PENSION AND OTHER POSTRETIREMENT BENEFITS: Alliant Energy has several non-contributory defined benefit pension plans that cover substantially all of its employees. Benefits are based on the employees' years of service and compensation. Alliant Energy also provides certain postretirement health care and life benefits to retirees. In general the health care plans are contributory with participants' contributions adjusted annually and the life insurance plans are non-contributory. The weighted-average assumptions as of the measurement date of September 30 are as follows: Qualified Pension Benefits Other Postretirement Benefits ------------------------------------ ----------------------------------- 2000 1999 1998 2000 1999 1998 ---------- ----------- ----------- ----------- ----------- ----------- Discount rate 8.00% 7.75% 6.75% 8.00% 7.75% 6.75% Expected return on plan assets 9% 9% 9% 9% 9% 9% Rate of compensation increase 3.5-4.5% 3.5-4.5% 3.5-4.5% 3.5% 3.5% 3.5% Medicare cost trend on covered charges: Initial trend range N/A N/A N/A 9% 7% 8% Ultimate trend range N/A N/A N/A 5% 5% 5-6% The components of Alliant Energy's qualified pension benefits and other postretirement benefits costs are as follows (in millions): Qualified Pension Benefits Other Postretirement Benefits ------------------------------------ ----------------------------------- 2000 1999 1998 2000 1999 1998 ----------- ----------- ----------- ----------- ----------- ----------- Service cost $11.1 $12.8 $13.8 $3.7 $5.5 $5.1 Interest cost 36.7 35.6 35.4 9.8 10.4 9.7 Expected return on plan assets (45.7) (46.2) (47.2) (5.3) (5.0) (3.7) Amortization of: Transition obligation (asset) (2.4) (2.4) (2.4) 3.9 4.3 4.7 Prior service cost 2.6 2.5 2.8 (0.3) (0.3) (0.3) Actuarial (gain) / loss (1.0) 0.2 (0.9) (1.9) (0.8) (1.2) ----------- ----------- ----------- ----------- ----------- ----------- Total $1.3 $2.5 $1.5 $9.9 $14.1 $14.3 =========== =========== =========== =========== =========== =========== During 1998 Alliant Energy recognized an additional $10.3 million of costs in accordance with SFAS 88, Employers' Accounting for Settlements and Curtailments of Defined Benefit Pension Plans and for Termination Benefits," for severance and early retirement programs. In addition, during 1999 and 1998, Alliant Energy recognized $0.5 million and $10.2 million, respectively, of curtailment charges relating to Alliant Energy's other postretirement benefits. The assumed medical trend rates are critical assumptions in determining the service and interest cost and accumulated postretirement benefit obligation related to postretirement benefit costs.

The projected benefit obligation, accumulated benefit obligation and fair value of plan assets for the pension plans with benefit obligations in excess of plan assets were $231.4 million, $225.9 million and $219.8 million, respectively, as of September 30, 1999. As of September 20, 2000, there were no pension plans with benefit obligations in excess of plan assets. 22 Alliant Energy sponsors several non-qualified pension plans that cover certain current and former officers. At December 31, 2000 and 1999, the funded balances of such plans totaled approximately $5 million. Alliant Energy's pension benefit obligation under these plans was $26.2 million and $28.0 million at December 31, 2000 and 1999, respectively. Alliant Energy's pension expense under these plans was $3.6 million, $2.5 million, and $4.5 million in 2000, 1999, and 1998, respectively. In 2000, Alliant Energy revised its deferred compensation plans allowing certain key employees and directors to defer payment of part or all of their current compensation in that participants can now elect to allocate their deferred compensation among a company stock account or an interest account, which are held in grantor trusts. At December 31, 2000, the value of the trusts totaled approximately $1 million. A significant number of Alliant Energy employees also participate in defined contribution pension plans (401(k) plans). Alliant Energy's contributions to the plans, which are based on the participants' level of contribution, were $8.1 million, $7.4 million and $7.7 million in 2000, 1999 and 1998, respectively. 4. RELATED PARTY ISSUES: In association with the merger, IESU, WP&L and IPC entered into a System Coordination and Operating Agreement which bcame effective with the merger. The agreement, which has been approved by the Federal Energy Regulatory Commission (FERC), provides a contractual basis for coordinated planning, construction, operation and maintenance of the interconnected electric generation and transmission systems of the three utility companies. 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. Such sales and purchases are allocated among the three utility companies based on procedures included in the agreement. The procedures were approved by both FERC and all state regulatory bodies having jurisdiction over these sales. Under the agreement, IESU, WP&L and IPC are fully reimbursed for any generation expense incurred to support the sale to an affiliate or to a non-affiliate. Any margins on sales to non-affiliates are distributed to the three utilities in proportion to each utility's share of electric production at the time of sale. 5. INVESTMENTS IN ASSOCIATE COMPANIES: Certain employee benefits costs billed to the operating companies have not yet been funded by the Company. The balance recorded in Account 123, Investments in Associate Companies, is a result of the operating companies, in turn, not yet paying the Company for such costs. The Company's corresponding benefits liabilities are recorded in Account 223, Advances from Associate Companies and Account 253, Other Deferred Credits. ---------------------------------------------------------------------------------------------------------------------------------- 23 ANNUAL REPORT OF ALLIANT ENERGY CORPORATE SERVICES, INC. ---------------------------------------- For the Year Ended December 31, 2000 ------------------ ----------------------------------------------------------------------------------------------------------------------- SCHEDULE XV STATEMENT OF INCOME ----------------------------------------------------------------------------------------------------------------------- ACCOUNT DESCRIPTION CURRENT YEAR PRIOR YEAR ----------------------------------------------------------------------------------------------------------------------- INCOME 457 Services rendered to associate companies $ 261,103,740 $ 242,566,385 458 Services rendered to nonassociate companies -
