The Telegraph reports that Porteous died at the weekend in the Italian Alps after he was slammed into a tree during an avalanche.
Porteous, 48, was skiing with a group of friends when he was caught in a violent snowfall and fatally injured.
The father-of-three was in a wooded area on the final day of his holiday when the group was struck by a wall of snow 45 feet across.
His friends were not buried and survived, but Porteous was propelled into a pine tree and later died.
Porteous was a manager for Mobil Oil before working for JP Morgan and UBS investment banks and Vitol, an energy and commodities trader.
