Where the money went

Every expense line on each return, biggest first: Form 990 Part IX (with its program, management and fundraising columns), 990-EZ Part I, or 990-PF Part I. Event marks lines the organization itself describes as events. “Events” in each summary adds those lines, conferences and meetings, and the direct costs of fundraising events. Unusual is not the same as improper. Many of these patterns have ordinary explanations. Check the filing.
