The Semiannual Report to Congress summarizes the results of OIG oversight, provides statistical information, and lists all reports issued October 1, 2015–March 31, 2016. During this reporting period, OIG audits, investigations, inspections, evaluations, and other reviews identified over $783 million in monetary benefits for a return of $13 for every dollar invested in OIG oversight. This reduction in return on investment from the preceding reporting period is not unexpected given that OIG continues to focus a significant portion of our resources on reviewing allegations related to wait time manipulation. This work generally does not result in a monetary benefit; rather, it focuses on improving access to health care for veterans. During this reporting period, OIG issued 158 reports and work products on VA programs and operations, made 741 recommendations, and conducted investigations that led to 185 arrests.
