LONDON, Oct 11 (Reuters) - ASOS, the British online fashion retailer, parted company with CEO Nick Beighton because he was not prepared to commit to stay for at least half of the group’s next five-year plan, its chairman said on Monday. That strategy will see ASOS accelerate its international expansion. “In looking at developing that strategy ... it’s not unusual to be honest for everyone to want to make sure that the right teams are in place both on the board and indeed on the exec team to go through at least the first half of that first five years,” Adam Crozier told Reuters. “It’s not unusual for the people involved in that, including executives to think about how committed they are to doing that,” he said. “In that conversation with Nick over the last little while we’ve sort of just come to the view jointly that he’s not going to be around for all of that ... It’s better to make the change now.” Crozier added that ASOS’s share price fall - down 42% before Monday’s update - was “unhelpful”.
