Sustainable Philanthropy 

Sustainable Philanthropy emphasizes practices, attitudes, and collaborations that foster equitable, resilient, stable, scalable, and compliant Donor, Exempt Organization, and Stakeholder interactions that give birth to perpetual giving, perpetual operations, and perpetual benefits.

This and the linked pages address the needs of:

  • Donors, to facilitate decisions on their path to Sustainable Philanthropy.

  • Exempt Organizations, their Boards of Directors, Executives, Employees, and the Volunteers who nurture their Donors and provide Public Benefits to their Stakeholders and Constituents.

  • Non-Profit Advisors – the Accountants, Attorneys, Financial and Insurance Advisors, Governance Consultants and other professionals who serve the Sustainable Philanthropic community’s needs.

  • Public Policy Makers and Gatekeepers – In the hope that we shed light on the consequences of your regulatory and legislative actions.

With that as prelude:

About our Archive-Library

As part of our commitment to client, financial advisor, and tax-practitioner awareness and education Cambyses and our affiliate (Steven Roy Management) write extensively on topics related to our practice service-matrix (and occasionally on topics that are far-afield from it). To avoid cluttering our service pages with things very few people ever read (OK, we acknowledge - a lot of this stuff is just plain boring to other people), we collect the most current of those writings in our Archive & Library.

The Archive-Library materials range from "readily understandable by anyone who can read" to "you'll probably need professional credentials and experience to assimilate this one." You can usually determine which you are looking at by reviewing the footnotes and end-notes. The more referenced articles are designed for our colleagues - in the spirit of cooperation, and in the hope that we can contribute something to our profession. 

Our goal is to produce a comprehensive body of authoritative and reliable materials viewed from the perspective of both Donors and Exempt Organizations. These materials are divided between a, more-or-less, linear main body narrative (the links from this page),  and a supporting cast of Technical and Procedural Notes, (the links from documents you reach from this page).

The main body narrative provides an overview and introduction to the installment topic: i.e., What the topic involves, where it fits in the philanthropic firmament, how to interpret it, information sources to facilitate interpretation, further study, and action, and digressions about its origin, purpose, and history. To the extent possible, the main body of the treatise is non-technical and provides general coverage of the most likely scenarios Donors, Organizations (and their personnel), and Advisors encounter.

Technical and Procedural Notes aim at users with a deep-seated need for sophisticated analysis. Technical and Procedural Notes address topics at a foundational level, dissecting rules, vocabulary, precedents, analytics, and exceptions at a level that addresses the needs of representatives who make and effectuate strategic decisions or advise and defend those who make them. Technical and Procedural Notes “read like an operations management, tax, or accounting textbook,” because that is exactly what they are intended to be! Note, however, that they are not a substitute for well-grounded professional input!

Note to our fellows and colleagues

Feel free to use any of our library materials in your own practice - just give us credit (and don't re-publish them without our permission and acknowledgement - that could get nasty). We welcome your feedback, constructive comments, and questions... we sometimes miss the obvious and your feedback helps remedy that. We view our colleagues as collaborators - not competition. There is plenty of work out there for all of us.

Apropos that last paragraph: Let us know what you do well - especially if it is a service we don't offer. We generate a "steady trickle" of referrals for other services and would be happy to add you to our referral list (after we've vetted you and  gotten to know you a bit). Contact us by email or phone to start the relationship.
