I thought it was $20B per speech.
It's like the number of undocumented workers in the US - the number goes up every time it's cited.
;-)
The NYTimes said that she got around $200k a speech, just like Geithner and similar former cabinet members were getting.
G-S wanted to impress their clients at a conference, so they were willing to pay HRC a bunch of money to have her speak at their event. That's the way conferences work.
She had a lot of direct knowledge of what was happening in the world (she traveled more than any previous SoS). Investors looking for "alternative investments" would find her thoughts on the subject valuable. G-S would get the benefit of having more clients interested in "alternative investments".
FWIW.
Cheers,
Scott.
