The interim consolidated financial statements included herein have been prepared by IEC, without audit, pursuant to the rules and regulations of the SEC. Accordingly, certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles have been condensed or omitted, although management believes that the disclosures are adequate to make the information presented not misleading. The consolidated financial statements include IEC and its consolidated subsidiaries (WP&L, IESU, IPC, Resources and Corporate Services). These financial statements should be read in conjunction with the financial statements and the notes thereto included in IEC's, IESU's and WP&L's latest Annual Report on Form 10-K. In the opinion of management, all adjustments, which are normal and recurring in nature, necessary for a fair presentation of (a) the consolidated results of operations for the three months ended March 31, 1999 and 1998, (b) the consolidated financial position at March 31, 1999 and December 31, 1998, and (c) the consolidated statement of cash flows for the three months ended March 31, 1999 and 1998, have been made. Because of the seasonal nature of IESU's, WP&L's and IPC's operations, results for the three months ended March 31, 1999 are not necessarily indicative of results that may be expected for the year ending December 31, 1999. Certain prior period amounts have been reclassified on a basis consistent with the 1999 presentation. 2. IEC's comprehensive income, and the components of other comprehensive income (loss), net of taxes, were as follows (in thousands): For the Three Months Ended March 31, 1999 1998 -------------- --------------- Net income $ 41,744 $ 28,875 Other comprehensive income (loss): Unrealized gain on securities, net of tax (1) 75,031 61,829 Foreign currency translation adjustments (614) 55 -------------- --------------- Other comprehensive income 74,417 61,884 -------------- --------------- Comprehensive income $ 116,161 $ 90,759 ============== =============== (1) Primarily due to the adjustment to the estimated fair value each quarter of IEC's investment in McLeod. IESU and WP&L had no comprehensive income in the periods presented. 8 3. Certain financial information relating to IEC's significant business segments is presented below: Regulated Domestic Utilities Nonregulated IEC ------------------------------------------- Electric Gas Other Total Businesses Other Consolidated ------------------------------------------------------------------------------------ (in thousands) Three Months Ended March 31, 1999 -------------- Operating revenues $351,338 $133,684 $9,204 $494,226 $53,199 ($570) $546,855 Operating income (loss) 68,615 23,939 2,354 94,908 (1,836) (85) 92,987 Net income (loss) 44,767 (1,906) (1,117) 41,744 Three Months Ended March 31, 1998 -------------- Operating revenues $357,751 $130,046 $8,409 $496,206 $60,322 ($245) $556,283 Operating income (loss) 55,837 22,376 1,831 80,044 (5,499) (665) 73,880 Net income (loss) 33,177 (3,999) (303) 28,875 Resources' (i.e. the nonregulated businesses) assets increased $150 million during the first quarter of 1999, primarily due to the increase in market value of its investment in McLeod and additional investments in foreign entities. Intersegment revenues were not material to IEC's operations and there was no single customer whose revenues exceeded 10% or more of IEC's consolidated revenues. 4. The provisions for income taxes are based on the estimated annual effective tax rate, which differs from the federal statutory rate of 35% principally due to: state income taxes, tax credits, effects of utility rate making and certain nondeductible expenses. 5. At March 31, 1999, IEC had $119.1 million of investments in foreign entities on its Consolidated Balance Sheets that included: (a) investments in several New Zealand utility entities; (b) investments in several generation facilities in China; and (c) an investment in an international venture capital fund. IEC accounts for the China investments under the equity method and the other investments under the cost method. The geographic concentration of IEC's investments in foreign entities at March 31, 1999, included investments of approximately $85.7 million in New Zealand, $32.9 million in China and $0.5 million in other countries. 6. In October 1998, the Board of Directors of IEC adopted a new Shareowner Rights Plan (new plan) to replace IEC's former plan that expired on February 22, 1999. The new plan was approved on January 15, 1999 by the SEC. On January 20, 1999, the Board of Directors declared a dividend of one common share purchase right (right) on each outstanding share of IEC's common stock which was issued on February 22, 1999 to coincide with the expiration of the former plan. Rights under the new plan will be exercisable only if a person or group acquires, or announces a tender offer to acquire, 15% or more of IEC's common stock. Each right will initially entitle shareowners to buy one-half of one share of IEC's common stock. The rights will only be exercisable in multiples of two at an initial price of $95.00 per full share, subject to adjustment. If any shareowner acquires 15% or more of the outstanding common stock of IEC, each right (subject to limitations) will entitle its holder to purchase, at the right's then current exercise price, a number of common shares of IEC or of the acquirer having a market value at the time of twice the right's per full share exercise price. The Board of Directors is also authorized to reduce the 15% thresholds to not less than 10%. 9 7. Summary financial information for Resources was as follows (in thousands): March 31, 1999 ------------ Current assets $84,950 Non-current assets 934,393 Current liabilities 40,468 Non-current liabilities (excludes minority interest) 208,785 Minority interest 6,162 Refer to the "Nonregulated Businesses" column of Note 3 for summary income statement data of Resources. 8. At the Annual Shareowners meeting on May 19, 1999, the shareowners approved a proposal to change the name of the corporation from Interstate Energy Corporation to Alliant Energy Corporation. The name change was effective May 20, 1999. 10 IES UTILITIES INC.

The interim consolidated financial statements included herein have been prepared by IESU, without audit, pursuant to the rules and regulations of the SEC.
