Regarding retail accounts, what is Vanguard's Fully Paid Lending (FPL) (Retail Securities Lending) fee split?

For funds, currently, their lending program for funds are extremely competitive (401(k)s and Pensions in this program are violating 29 U.S.C. § 1106 (ERISA § 406)), but for retail, their fee split is hidden, so does anyone have an account that can share their fee split for Vanguard's Fully Paid Securities Lending Program?

Here is the website that does not include the ratio.
