Apparently there is conflict going around on how to interpret the functional expense allocation information for Wounded Warrior Project.
All their info is laid out in their audited financial statements, which you can find here. Their annual report, audited financial statements, and 990s for the last eight years are all available on their website. Good on them for making all that info readily available. That is an example for all charities to follow.
How can three different calculations all be correct?
