Material Changes vs. Prior Period
- Significant Earnings Recovery: Net income surged to $315.7 million in 2006 compared to a net loss of $7.7 million in 2005. This reversal was driven by the absence of a $334 million pre-tax asset valuation charge related to Brazil investments recorded in 2005 and a $254 million pre-tax gain from the sale of Alliant Energy New Zealand Ltd. (AENZ) stock in 2006.
- Utility Margin Pressures: Despite the overall earnings recovery, utility electric margins decreased by 10% ($126 million) in 2006. This was primarily due to $160 million in higher purchased power capacity costs following the sale of nuclear interests (Duane Arnold and Kewaunee) and unfavorable weather hedging results.
- Divestitures: The company completed the sale of its Brazil investments (Jan 2006) and New Zealand investments (Dec 2006). It also sold its Illinois utility operations in Feb 2007 (post-year-end) and announced a definitive agreement to sell IPL's electric transmission assets for approximately $750 million (Jan 2007).
- Debt Reduction: Long-term debt decreased significantly from $2.15 billion in 2005 to $1.52 billion in 2006, aided by proceeds from asset sales and the retirement of $358 million in Resources senior notes.
Guidance, Outlook, and Risks
- Strategic Focus: Management is shifting focus to the utility business as the primary growth platform, with substantial capital investment planned for 2007-2013 in new generation (wind and clean-coal) to meet demand and renewable standards.
- Capital Expenditures: Anticipated construction and acquisition expenditures are $535 million for 2007 and $1.085 billion for 2008, heavily weighted toward utility generation and environmental compliance.
- Regulatory Risks: The company faces uncertainty regarding rate recovery for fuel costs, particularly at WPL in Wisconsin, where retail electric margins are exposed to commodity price volatility. New environmental regulations (CAIR, CAMR) are expected to require significant capital investments ($170M-$225M for IPL and $100M-$140M for WPL by 2010).
- Operational Risks: Risks include the potential impact of the Calpine Corporation bankruptcy on purchased power agreements (RockGen), weather volatility affecting sales volumes, and the outcome of the proposed sale of IPL's transmission assets.
- Dividend Outlook: In Dec 2006, the annual common stock dividend was increased from $1.15 to $1.27 per share. The company targets a payout ratio of 60-70% of utility earnings.
Investor Verification Checklist
- Asset Sale Proceeds: Verify the final net proceeds and regulatory treatment of the sale of IPL's transmission assets (announced Jan 2007) and the Mexico resort divestiture.
- WPL Fuel Cost Recovery: Monitor the Public Service Commission of Wisconsin (PSCW) proceedings regarding WPL's retail electric fuel cost recovery mechanisms and potential changes to the current monitoring ranges.
- Environmental Compliance Costs: Track actual capital expenditures against the estimated ranges for CAIR and CAMR compliance to assess potential rate case impacts.
- Calpine Bankruptcy Impact: Assess the resolution of the RockGen Energy Center purchased power agreement and any potential replacement power costs.
- Weather Hedging Effectiveness: Review the performance of weather derivative contracts in 2007, given the losses incurred in 2006 due to a lack of correlation between Chicago and local weather indices.
