Abstract: An assessment of the wealth impact of spin-offs involving UK firms is of interest, as they tend to access debt through banks rather than capital markets. Banks will have a different relationship with shareholders, so the distribution of returns may differ from that previously observed. The short and long-term impact on both parent and spin-off shareholders is investigated. Possible reasons for a positive returns response, including an anticipated acquisition premium, and management focus related gains, are considered. Annual financial ratios offer a further evaluation of operating performance and assess the impact on levels of leverage in parents and spin-offs.
