In the last 10 years, Vivendi's annual turnover fell from €29 billion to €10 billion after it divested high profile assets including Universal Music Group. But shareholders — which include Bolloré — have gotten richer in the process. Bolloré scored a major coup by listing Universal Music Group and giving Vivendi shareholders ownership of 60% of the music powerhouse whose talent roster includes Taylor Swift and Drake. In its first day at the Euronext Amsterdam exchange, UMG's shares skyrocketed by 39% to reach a valuation of nearly $53 billion.
