I don't know anyone who knows and I sure don't. I found out in 1997 that they were settling out-of-court lawsuits when Harry Peloyan, the Awake! editor, wrote me a letter and in one paragraph mentioned to me that in the past the Society settled many "megabuck lawsuits" out-of-court. It was the content of that letter that made me completely close the door to the WT once and for all.
If someone wants to know if there has been a settlement made by a plaintiff with WT in your area, go to your court house and ask to see any documents with Watch Tower or Watchtower in the name of the lawsuit. In some states it can be done using the computer, but in small towns, not so.
I would guess that's the only way the number of settlements could be compiled.
There were two lawyers at Bethel working full time on domestic violence lawsuits and child abuse lawsuits, William Bell and Carolyn Wah. They made the deals and paid out the money. The majority of victims or their parents agreed to take on average in the 1990s, $2,500. These were desperate people who needed money to pay for their child's therapy.
Even today, in a (secret, but not to me) recent out-of-court settlement, the victims settled because they were desperate for money so they could get therapy for depression, etc., and just couldn't take a chance that they would lose if their case went before a jury. That's what WT has always counted on before Candace Conti's lawsuit. They just weren't prepared that she would go all the way to jury and it's successful conclusion on June 13th and 14th. This is why WT attorneys were shocked out of their wits when they lost in such a big way.
