Base salaries
Yes, she makes a little less than her predecessor, at least at first, which is pretty common in any job. But a lot of execs at this level have all manner of perks that make being shorted a hundred grand or so seem like someone forgetting to kick in a buck for their share of a tip. Some examples include: huge sign-on bonuses, "car expense" (essentially, buy whatever car you want on us), relocation/travel/commuting reimbursement, housing expense, wardrobe, even little things like free dry cleaning and magazine subscriptions are included.
My general point is, trying to measure what an exec at this level actually makes from a base salary is like trying to understand the national debt without taking into account trade agreements and all manner of other arrangements between countries.
