[Excerpt] This semiannual report covers the activities of the Department of Labor's Office of Inspector General for the period April 1 through September 30, 1987. During this period, audit initiatives resulted in numerous economy and efficiency findings and recommendations regarding Agency operations: the OIG issued 120 audit reports on program activities, grants and contracts. Investigative results continued to show positive progress during this reporting period: 633 investigations were opened, 599 cases were closed, and there were 582 indictments and 427 successful prosecutions. The Office of Labor Racketeering (OLR) has expanded its focus from the more traditional organized crime elements to investigations of corruption in employee benefit plans by accountants, attorneys, bankers and other fund administrators and advisors. This area remains its highest investigative priority. During the six-month reporting period, OLR investigations resulted in 87 indictments and 61 convictions, with additional predicate established for the potential civil recovery of approximately $18 million.
