This article is our philanthropic entry. As the author notes: ?Family offices and philanthropy have had a long marriage. This relationship is part of the most basic function of how a family manages its assets and how it decides to give to causes most important to the family members. This sensitive work transcends generations and reflects the family's legacy and deepest values.? The article details the founding of the National Philanthropic Trust (NPT) in 1996, near Philadelphia, supported by the Pitcairn family office, to provide a simple way for families to contribute to philanthropic funds. By offering donor-advised funds, NPT has been very successful. Since its founding, NPT has raised more than $10 billion and manages charitable assets of about $6.2 billion. Together with its donors - many of which are family office clients - they have distributed another $5 billion to charitable organisations. In 2013 NPT opened a London office, NPT UK, and its donors have continued to increase their cross-border giving. By leveraging and investing in philanthropic trends, such as international giving and technology, NPT donors recommended 37,000 grants worth almost $1 billion to charities in 31 different countries in 2017.
