IPL - The articles of incorporation of IPL contain a provision that grants the holders of its preferred stock voting rights to elect two members of IPL’s Board of Directors if preferred dividends equal to the annual dividend requirements are in arrears. Such voting rights would not provide the holders of IPL’s preferred stock control of the decision on redemption of IPL’s preferred stock and could not force IPL to exercise its call option. Therefore, IPL’s preferred stock is presented in total equity on Alliant Energy’s and IPL’s Consolidated Balance Sheets in a manner consistent with noncontrolling interests. In February 2013, IPL announced it will redeem all 6,000,000 outstanding shares of its 8.375% cumulative preferred stock in March 2013 at par value for approximately $150 million plus accrued and unpaid dividends to the redemption date. Alliant Energy and IPL expect to record a $5 million charge in the first quarter of 2013 related to this transaction in “Preferred dividend requirements” in their Consolidated Statements of Income. WPL - The articles of organization of WPL contain a provision that grants the holders of its preferred stock voting rights to elect a majority of WPL’s Board of Directors if preferred dividends equal to the annual dividend requirements are in arrears. The exercise of such voting rights would provide the holders of WPL’s preferred stock control of the decision on redemption of WPL’s preferred stock and could force WPL to exercise its call option. Therefore, the contingent control right and the embedded call option cause WPL’s preferred stock to be presented outside of total equity on Alliant Energy’s and WPL’s Consolidated Balance Sheets in a manner consistent with temporary equity. In February 2013, WPL announced it will redeem all 1,049,225 outstanding shares of its 4.40% through 6.50% cumulative preferred stock in March 2013 for approximately $61 million plus accrued and unpaid dividends to the redemption date. Alliant Energy and WPL expect to record a $1 million charge in the first quarter of 2013 related to this transaction in “Preferred dividend requirements” in their Consolidated Statements of Income.
