"

Are we getting a bit informal?
In the sentence here: ""In the first quarter of 2008 Ian Kerr left his position as CEO, to be replaced by Bert Pijls. Egg is managed under the blanket of Citi EMEA. Which essentially means that Bert controls all Citi operations within Europe, the Middle East and Asia when formulating strategy.""  Using 'Bert' seems a little too informal, presuming it is his first name. Any thoughts?"
