Item 1.  Acquisition or Disposition of Assets

Vectren Corporation (Vectren), the registrant, is an Indiana
corporation organized on June 10, 1999 solely for the
purpose of effecting the merger of Indiana Energy, Inc.
(Indiana Energy) and SIGCORP, Inc. (SIGCORP) with and into
Vectren and carrying on the combined business of Indiana
Energy and SIGCORP.  On March 31, 2000 the merger of Indiana
Energy with SIGCORP and into Vectren was completed.  The merger
was a tax-free exchange of stock and is being accounted for
as a pooling of interests.  Each outstanding common share,
no par value of Indiana Energy was converted into one share
of the common stock, no par value, of Vectren, and each
outstanding common share of SIGCORP was converted into 1.333
common shares of Vectren.

Indiana Energy was a public utility holding company with
subsidiaries and affiliates engaged in natural gas
distribution, gas portfolio administrative services and
marketing of natural gas, electric power and related
services.  As a result of the merger, each of Indiana
Energy's 14 former subsidiaries is now a subsidiary of
Vectren.

SIGCORP was a public utility holding company with
subsidiaries engaged in the production, transmission and
distribution of electric energy, the distribution and sale
of natural gas and related services.  As a result of the
merger, each of SIGCORP's 11 former subsidiaries is now a
subsidiary of Vectren.

Indiana Gas Company, Inc. (Indiana Gas) and Southern Indiana
Gas and Electric Company (SIGECO) are the primary subsidiaries
of Vectren.  Both are operating public utilities.  Indiana
Gas provides gas utility service in central and southern
Indiana.  In 1999 Indiana Gas supplied gas to 500,000
residential, small commercial and contract (large commercial
and industrial) customers in 311 communities in 49 of 92
counties in the state of Indiana.  SIGECO provides
generation, transmission, distribution and sale of electric
power and the distribution and sale of natural gas in
southwestern Indiana.  In 1999 SIGECO supplied electric
power to approximately 125,000 customers in Evansville,
Indiana and 74 other cities, towns, communities and adjacent
