In 2004, Zuma became a key figure mentioned in the Schabir Shaik trial. Shaik, a Durban businessman and his financial advisor, was questioned over bribery in the course of the purchase of Valour class frigates for the South African Navy, a proposed waterfront development in Durban, and lavish spending on Zuma's residence in Nkandla. In the trial, Shaik was shown to have solicited a bribe of R500,000 per annum for Zuma in return for Zuma's support for the defence contractor Thomson-CSF, documented in the infamous "encrypted fax". On 2 June 2005, Shaik was found guilty and sentenced to 15 years in prison.
