The main purpose of the company, which is government-owned but is not a government corporation, is to locate assets in Israel belonging to victims of the Holocaust and restore them to their legal heirs. ... Any proceeds from the sale of unclaimed assets must go to charities, institutions or other organizations that benefit Holocaust survivors. The money can also be used for such things as Holocaust education or commemoration. Since its establishment, Hashava says, it has distributed some 500 million shekels ($145 million) in aid to survivors.
