Alliant Energy Announces 2012 Results

MADISON, Wis., Feb. 14, 2013 /PRNewswire/ -- Alliant Energy Corporation (NYSE: LNT) today announced U.S. generally accepted accounting principles (GAAP) and non-GAAP consolidated unaudited earnings from continuing operations for 2012 and 2011 as follows:

"In 2012, we delivered solid financial results," said Patricia Kampling, Alliant Energy Chairman, President and CEO.  "Consistent with our long-term earnings growth goal, our non-GAAP weather adjusted earnings increased by 5% over calendar year 2011."

Utility and Corporate Services - Alliant Energy's Utility and Alliant Energy Corporate Services, Inc. (Corporate Services) operations generated $2.87 per share of non-GAAP earnings per share (EPS) from continuing operations in 2012, which was $0.10 per share higher than 2011.  Income tax impacts at IPL due to Iowa rate-making practices, lower generation operation and maintenance expenses, higher WPL retail fuel cost recovery, and higher AFUDC related to emission control projects led to higher EPS in 2012 when compared to 2011.  These positive EPS drivers were partially offset by higher depreciation expense, higher capacity charges for nuclear purchased power agreements, and record warm weather in the first quarter of 2012, negatively impacting electric and gas sales.  The weather impact on electric and gas sales was $0.12 per share and $0.16 per share in 2012 and 2011, respectively.

Non-regulated and Parent - Alliant Energy's non-regulated and parent operations generated $0.18 per share of non-GAAP EPS from continuing operations in 2012, which was the same as 2011.

Earnings Adjustments - 2012 non-GAAP EPS excludes net losses of $0.12 per share from adjustments consisting of increased tax obligations at the utilities due to state tax apportionment changes due to the RMT sale and regulatory-related credits.  2011 non-GAAP EPS excludes net losses of $0.03 per share from adjustments consisting of impairment charges, regulatory-related charges and credits, charges related to an amendment to Alliant Energy's Cash Balance Pension Plan, charges for emission allowance contracts and the reversal of deferred tax valuation allowances.  Non-GAAP adjustments, which relate to material charges or income that are not normally associated with ongoing operations, are provided as a supplement to results reported in accordance with GAAP.  Refer to page 5 of this document for additional details of the earnings adjustments for 2012 and 2011.

Non-recurring state income tax impacts in 2012 - Alliant Energy utilizes state apportionment projections to record its deferred tax assets and liabilities for each reporting period.  These state apportionment projections are significantly impacted by the estimated amount of revenues expected in the future from each state jurisdiction for Alliant Energy's consolidated tax group, including both its regulated and non-regulated operations.  The forecasted amount of revenues from each state jurisdiction for Alliant Energy's consolidated tax group changed in the first quarter of 2012.  This resulted from the planned sale of the RMT business.  The change in the state apportionment projections resulted in non-recurring state income tax charges of $15 million ($8 million at IPL and $7 million at WPL), or $0.14 per share in the first quarter of 2012.

Income tax impacts at IPL due to Iowa rate-making practices associated with mixed service and repairs projects - In 2012, the Internal Revenue Service audit process to review the elected change in accounting method for allocation of mixed service costs and repairs expenditures was completed.  Prior to 2012, tax expense and benefits related to mixed service costs and repairs book to tax differences were recorded in the tax benefit rider regulatory liability.  Upon completion of the IRS audit process, the tax expenses and benefits related to mixed service costs and repairs began flowing through the income statement in 2012 pursuant to Iowa rate-making practices.  The impact of the changes in income tax impacts at IPL due to Iowa rate-making practices associated with mixed service and repairs projects resulted in a positive year-over-year variance of $0.12 per share.

Weather impact on electric and gas sales - Weather in Alliant Energy's service territory in the first quarter of 2012 was among the warmest on record with approximately 22 percent fewer heating degree days than normal.  Even though the summer of 2012 was warmer than 2011, it was not enough to offset the first quarter negative EPS impact.  The impact of the changes in weather on Alliant Energy's electric and gas sales resulted in a negative year-over-year variance of $0.04 per share.

Regulatory-related credits from WPL retail rate case decision in June 2012 - In July 2012, the Public Service Commission of Wisconsin (PSCW) issued its written order on the 2013/2014 test period electric and gas retail rate case request filed by WPL.  The regulatory-related credits from this decision resulted in an increase in earnings of $0.02 per share in the second quarter of 2012.

2013 Earnings Guidance

Alliant Energy is affirming its 2013 earnings per share guidance as follows:

Utility and Corporate Services

$2.90 - $3.10

Non-regulated and Parent

0.05 - 0.15

Alliant Energy Consolidated

$2.95 - $3.25

"In 2013, we expect to continue to see the earnings benefit of our rate base growth initiatives, while at the same time we anticipate the tax benefit riders in Iowa, and continued cost controls across the service territory, will help ensure we maintain competitive rates," said Patricia Kampling, Alliant Energy Chairman, President and CEO.

The 2013 earnings guidance does not include the impacts of any non-cash valuation adjustments, regulatory-related charges or credits, reorganization or restructuring charges, discontinued operations, future changes in laws or regulations, charges related to preferred stock redemptions, adjustments made to deferred tax assets and liabilities from valuation allowances, pending lawsuits and disputes, federal and state income tax audits and other Internal Revenue Service proceedings or changes in generally accepted accounting principles that may impact the reported results of Alliant Energy.

Drivers for Alliant Energy's 2013 earnings guidance include, but are not limited to:

  • Stable economy and resulting implications on utility sales
  • Normal weather and operating conditions in its utility service territories
  • Ability of IPL and WPL to earn their authorized rates of return
  • Regulatory decisions impacting earnings at IPL from tax initiatives
  • Ability of WPL to recover future purchased power, fuel and fuel-related costs through rates in a timely manner
  • Continuing cost controls and operational efficiencies
  • Execution of IPL's and WPL's capital expenditure plans
  • Consolidated effective tax rate of 14%
