(a) Income Statement amounts have been adjusted for discontinued operations.

(b) Excludes adjustment for minority interest in consolidated subsidiaries or income or loss from equity investees.

(c) NiSource is a public utility following SFAS 71 and therefore does not add amortization of capitalized interest or subtract interest capitalized in determining earnings, nor reduces fixed charges for Allowance for Funds Used During Construction.

(d) Preferred dividends, as defined by SEC regulation S-K, are computed by dividing the preferred dividend requirement by one minus the effective income tax rate applicable to continuing operations.

(e) NiSource made correcting adjustments for the years ended December 31, 2010, 2009, 2008 and 2007. NiSource does not believe these corrections are material for any reported period. Refer to Form 10-K for the period ended December 31, 2011 for additional information.
