That expenses chart is from 2013, which is before the ice-bucket challenge thingy started. That means that you can't be sure that all the money hasn't gone to research just because of how the ALS Foundation budgeted earlier this year. If you could imagine keeping the amount of money they spent on the other slices of the pie equal, but inflating the research part with the money raised through the ice-bucket challenge, you'd probably find that the percent spent on research and education makes up most of the pie.
