Donor advised funds generally receive funds from one donor and are subject to significant restrictions on any payments to donors, donor advisors or related parties. Single-entity funds and global support funds receive funds from multiple funding sources and make payments to one pre-designated grantee. Donors do not receive compensation or reimbursement through granted funds but fund managers may if they are employed or engaged by the grantee. Collective Action Funds generally receive funds from multiple sources; Tides monitors grants from Collective Action Funds to avoid improper conflicts of interest.
