People paid by the organization

None of the 8 people listed on these returns reported compensation from the organization. They are listed below.

Officers and directors, no compensation reported

8 people listed on the returns with $0 (or no amount) in every compensation column: current people first. Hours are as filed on the latest return each person appears on.

People by year

Highest-paid independent contractors

No independent contractors reported.

Who the money went to

Grants this organization reported paying: Schedule I Part II of the Form 990, or the grants-paid list on the 990-PF. Open a year for every recipient. Recipients link to their own page when the grant names an EIN we have (990-PF grants list no EIN, so those link only on an exact, unique name and state). Grants to individuals are counted; their names are not shown.

Negative amounts are returned or refunded grants; they are listed last and left out of the totals of grants paid.

Who gave

No contributors are listed on Schedule B in the e-filed returns we have for this organization.

Finances

Funders of this organization

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.
