I haven't read the 175 page report {Found at https://www.gefraud.com/}, so I will have to reserve my judgement on the whole thing, but I did find the GE Rebuttal to be very short on dealing with the actual allegations (more an attempt to deflect) https://www.genewsroom.com/press-releases/ge-addresses-claims-harry-markopolos
There seems to be a large oil and gas component to the allegations (although health insurance seems to be the biggest area of concern)
