During a long and distinguished career in treasury, Erhard Wehlen, the group treasurer of gas and engineering group Linde, has found one recurring theme that runs through the decades. Referring to the topics discussed at the TalkingTreasury conference (see page 40), Wehlen says: “The major part of the discussion shows that treasury is a function where you have to cope with whatever the business and economic environment presents to you. And that sometimes can be a challenge.”
