Wow, that's insane. Spending $50m/year to notify people and process these claims could easily be justified given the sheer size of the assets being held.

When we wrote this software, we tried hard to get a follow on contract to fix this 180 day problem using more automation. But, there was no budget, and the claims processors did not want to lose their jobs. We toured the location where they process the claims. They literally had piles of filing boxes containing the submitted claim forms in a secured room. I forget how many they do per day, but I remember being surprised at the volume. The site does many millions of searches per month...
