These costs relate primarily to employee and executive severance, transaction costs, and other merger, integration and restructuring activities. As a result of merger integration activities, management has identified certain information systems that are expected to be retired in 2001. Accordingly, the useful lives of these assets have been shortened to reflect this decision. These information system assets are owned by a wholly owned subsidiary of Vectren and the fees allocated by the subsidiary for the use of these systems by Indiana Gas are reflected in operation and maintenance expenses in the accompanying condensed financial statements. As a result of the shortened useful lives, additional fees were incurred by VUHI. For the twelve months ended June 30, 2001 and for the year ended December 31, 2000, these additional fees increased operation and maintenance $13.6 million and $11.4 million, respectively. In total, merger and integration related costs and restructuring costs incurred for the twelve months ended June 30, 2001 and for the year ended December 31, 2000 were $28.7 million ($17.8 million after tax) and $44.1 million ($31.6 million after tax), respectively. Before merger and integration and restructuring charges, VUHI's ratio of earnings to fixed charges for the twelve months ended June 30, 2001 was 2.4 and for the year ended December 31, 2000 was 3.2. (2) In 1997, the Indiana Gas Board of Directors authorized management to undertake the actions necessary and appropriate to restructure Indiana Gas' operations and recognize a resulting restructuring charge of $39.5 million ($24.5 million after tax) which included estimated costs related to involuntary workforce reductions. VUHI's ratio of earnings to fixed charges for 1997 before restructuring costs was 3.6. (3) Net income, as defined, is before preferred stock dividend requirement of subsidiary and cumulative effect of change in accounting principle.
