During Charlie's tenure, we have been widely recognized as an international leader in a number of areas which include environment, sustainability, safety and governance. Charlie has also given freely of his personal time to make a difference in many aspects of the community.

With the industry experience and business judgment that Marvin Romanow brings to the table, we are confident in the future of the company under his leadership," said Francis Saville, Nexen's Chairman.
