Does anyone have any idea about what exactly constitutes the "Other" column ? I don't know how to read the table for a foundation, so it's not clear if it's just "bonuses", taken from the general budget, or if it might be something else (say, "speaker fees" or "consulting" gigs that are done in his name, but channel through the foundation, etc... No idea what I'm taking about, here, so just curious !)
