Ridha D.M. Wirakusumah. JAKARTA (Reuters): Indonesian President Joko Widodo on Tuesday (Feb 16) announced the appointment of a senior banker, Ridha D.M. Wirakusumah, as the chief executive of the country's new sovereign wealth fund, which has a target of managing US$20 billion in funds. Jokowi, as the president is popularly known, also named other professionals for posts on the board of directors of the fund, the Indonesia Investment Authority (INA). The INA aims to attract foreign funds as co-investors, unlike some funds set up by other countries to manage oil revenues or foreign exchange reserves. There has been scrutiny over the governance of INA particularly in the wake of a corruption scandal and massive losses involving neighbouring Malaysia's 1MDB fund.
