I'm having a hard time figuring out what "Cumulative average annual loss" exactly means.
That is something I am uncertain about too.
And where are the HR's?
The HR numbers are in the report. I dropped them from the graph as I considered the AA-E credit ratings to be more interesting and the HRs really spiked the chart.
Also there was no "Prosper Rating" system before registration. At that time they used the old credit grade system.
I wonder about this too.
Prosper could retroactively sample the data based on their new qualifications. But Prosper also recently changed their qualifications for their Prosper rating system. So is it Prosper's New rating system or Prosper's Newer New rating system. That is part of why I posted the graphs.
Honestly, they look pretty odd. There is a lot of very unusual shifts early on and they all strangely flatten out at 28 months.
