The need for this guidebook is clear. Donors have made large gifts to charitable causes only to have the funds eventually spent on purposes they never would have supported. All too often, the trustees and staff of grantmaking institutions drift from intended goals, lose accountability, or pay insufficient attention to the principles that governed their founders' charitable giving. In some cases, assets have been put to uses that would have repelled the original benefactors, turning a generous and well-intentioned gift into a punchline. This guidebook offers detailed guidance to philanthropists who want to ensure that the assets they dedicate to charity are disbursed as they intend. It identifies common pitfalls, explains relevant tradeoffs, and describes successful strategies used by other donors. It lays a broad range of options before you, and suggests ways you can define, secure, and perpetuate your charitable intentions.
