Key Financial Metrics

Material Changes vs. Prior Period

• Profitability Surge: Net income improved significantly from a loss of $1.6 million in Q1 2006 to $63.9 million in Q1 2007. This turnaround is primarily attributed to the absence of a $90.8 million "Loss on early extinguishment of debt" recorded in Q1 2006 and a $14.7 million loss from discontinued operations in the prior year.
• Revenue Decline: Total operating revenues decreased 2% to $912.7 million. Electric utility revenues dropped 5% ($553.5M vs $583.0M) due to lower fuel-related cost recovery revenues and the sale of Illinois distribution properties. Non-regulated revenues increased 45% ($52.9M vs $36.4M) driven by higher WindConnect construction management revenues.
• Winter Storm Impact: IPL incurred approximately $24 million in incremental capital expenditures and $7 million in operating expenses in Q1 2007 due to severe winter storms in February. Total estimated storm costs are approximately $60 million.
• Asset Sales: In Q1 2007, IPL and WPL completed the sale of their Illinois electric and gas distribution properties, receiving net proceeds of $51 million combined. Proceeds were used primarily to reduce short-term debt.

Guidance, Outlook, and Risks

• Transmission Asset Sale: IPL signed a definitive agreement to sell its electric transmission assets in Iowa, Minnesota, and Illinois to ITC Midwest LLC for approximately $750 million. The transaction is expected to close in Q4 2007, with estimated net proceeds of $475 million to $525 million after taxes and costs.
• Divestitures: Alliant Energy announced a definitive agreement to sell its Mexico investment, with closing expected in May 2007.
• Capital Expenditures: 2007 construction and acquisition expenditure estimates were increased by $45 million for both Alliant Energy ($580M total) and IPL ($335M total) to account for winter storm restoration costs.
• Regulatory Matters: WPL received an oral decision from the Wisconsin Public Service Commission regarding its proposed wind project, proposing a return on common equity of 10.50%. WPL is also evaluating a potential rate reduction for 2007 due to lower-than-forecasted fuel costs.
• Share Repurchases: The company repurchased 3.4 million shares for $144 million in Q1 2007. As of April 30, 2007, $151 million remained available under the repurchase authorization.
• Risks: Key risks include the impact of weather on demand and margins, regulatory approval of the transmission asset sale, fuel price volatility, and the outcome of ongoing IRS audits for tax years 1999-2004.

Investor Verification Checklist

• Transmission Sale Closing: Verify the regulatory approval status and expected closing date of the $750 million IPL transmission asset sale to ITC Midwest.
• Storm Cost Recovery: Confirm whether IPL will seek rate recovery for the $60 million in winter storm costs or if these will be absorbed as a permanent earnings reduction.
• Divestiture Proceeds: Monitor the closing of the Mexico investment sale and the actual net proceeds realized from the Illinois asset sales.
• Regulatory Rate Decisions: Track the final outcome of WPL's 2007 retail rate case and the potential impact of the proposed rate reduction due to fuel cost over-recovery.
• Debt Reduction Strategy: Assess how proceeds from asset sales are being allocated between debt reduction, capital expenditures, and share repurchases.
