MACQUARIE Group is moving to surrender the management of another of its infrastructure satellites, this time Duet Group, which has outlined a proposal to internalise its management. Macquarie Bank and AMP will receive $82 million in Duet scrip if the move wins shareholder support. They will receive a further $11 million to cover reorganisation expenses during the transition period, along with $5 million in advisory fees. Both payments will be in cash. A range of other infrastructure companies such as Spark and Hastings Diversified, either have, or are considering internalising their management. Macquarie satellites that have internalised management include Macquarie Leisure, Macquarie Media, and its toll-road arms. Internalising management improves shareholder returns since it removes the need to pay performance fees to the management company if the shares outperform a specified sharemarket index.
