There is at least some figures that are wrong on this site since they list exec comp as only $1.1M, then right below the total exec comp is around $2.5M or $3M if you include their other exec comp.
Officer compensation may be included in charitable disbursements, so Percent of Total Expenses may add up to greater than 100%.
It could also be a data parsing error from ProPublica. The information ProPublica displays is extracted with automated systems from the foundation tax forms (their database contains hundreds of thousands of forms added annually, so manual extraction is out of the question). Any little reporting anomaly can cause such mistakes, but reading the tax form itself gives a clear picture.
This is clearly stated, both on ProPublica's site and in the IRS Form 990 that it's sourced from.
