Oct. 3 (Bloomberg) -- The London Metal Exchange board approved a third-party review to prove warehouses and trading companies are keeping their operations separate, Martin Abbott, chief executive officer of the exchange, said.

“We are proceeding as we said with the introduction of the third-party audit,” he said in an interview in London today.

The change will take effect April 1, Diarmuid O’Hegarty, deputy CEO of the exchange, said. “We still have to give a notice period to the warehouse companies.” New rents usually take effect every April 1.
