Restructuring the company
In September of 2005, Ian Russell (Scottish Power's former Chief Executive) was faced with a growing threat from the stock market as the company's shares had recently soared causing rumours of its German rival, and owner of Powergen, E.ON wanting to buy the company. After meeing with the chairman, Charles Miller Smith, and the finance director, Simon Lowth, it was decided that a major restructuring had to take place - one that involved getting rid of two of his top executives - David Nish and Charles Berry. Along with these sackings, the human resources director, Mike Pittman, and the communications chief, Dominic Fry were dismissed as well. Mr. Russell's explanation referred back to late May when Scottish Power announced the £5.1 billion sale of its giant US business PacifiCorp to the world-famous entrepreneur Warren Buffet. PacifiCorp was responsible for two-thirds of Scottish Power's valuation, which meant that the company would become much smaller when the deal went through. The idea of the restructuring was to slim down the group - stripping out the four directors in the process - preparing it for life as a smaller, independent, predominantly UK-based utility. However, Mr. Russell did not mention that the group's smaller size was what had attracted E.ON's attention or that the downsizing was threatening the independence of one of Scotland's biggest companies. To this day, Mr. Russell has yet to publicly link the two events - despite the asking of questions in parliament. Neither did he bring up the £9 million in shares, pension payments and other incentives he could make from a deal. Later that same day, E.ON confirmed that it was considering its options regarding a possible takeover of Scottish Power.
Since David Nish was most likely to succeed Ian's position, the group's head of infrastructure, finance director and Mr. Russell's right-hand man was most surprised with his dismissal.
