Corrupt Practices Act. Climate controversy, 2018 In November 2018, about a dozen climate activists played tennis inside Credit Suisse agencies (of Lausanne, Geneva and Basel simultaneously), disrupting operations as a protest against the bank's investments in fossil fuels. Credit Suisse lodged a complaint and the activists from Lausanne were tried in January 2020 and fined 21,600 CHF. They were later cleared of all charges in what a Swiss media outlet considered a 'historical decision'. The tennis theme was chosen to urge Swiss tennis star Roger Federer to break his connection with Credit Suisse as a sponsor due to the company's participating in the climate crisis (notably by multiplying 16-fold its financing for coal from 2016 to 2017). On 11 January 2020, Federer published a statement saying: "[...] I have a great deal of respect and admiration for the youth climate movement, and I am grateful to young climate activists for pushing us all to examine our behaviours", and further committed to a dialogue with his sponsors on social issues. On 24 January 2020, following the trial, the climate activist group emitted a press statement requesting a transparent, televised debate with the CEO of Credit Suisse. With no answer from the bank, they created a website under the name "DiscreditSuisse" hosting content pertaining to Credit Suisse's record on climate issues. Espionage scandal, 2019 In 2019, a senior executive who was leaving the firm discovered that Pierre-Olivier Bouée, the chief operating officer (COO) of Credit Suisse at the time, had hired private detectives to follow him to see if he was wooing Credit Suisse clients. Bouée was fired, and a private investigator involved in the surveillance apparently killed himself. Greensill Capital, 2021 In March 2021, Credit Suisse closed and liquidated several supply-chain investment funds tied to the activities of Greensill Capital. The investors in the funds, which totalled assets of approximately $10 billion, were expected to lose $3 billion as of March 2021. Credit Suisse has returned around $5.9 billion to investors in its Greensill-linked funds. Archegos Capital, 2021 In April 2021, at least seven executives were removed from their posts after Credit Suisse reported losses of $4.7 billion linked to its prime brokerage services provided to Archegos Capital. The executives who departed included Lara Warner, the group's chief risk and compliance officer, and Brian Chin, head of the investment bank. Just prior to Credit Suisse's 2021 Annual General Meeting, Andreas Gottschling,
