Restatements are detected by comparing every vintage of a fact across all of ALLIANT ENERGY CORP's filings back to 1993. A revision is not by itself a sign of wrongdoing — companies re-file for many legitimate reasons. This list is not exhaustive: it shows LNT's most significant revisions, and a figure absent from it has not been certified as unrevised.
