The ABCs of PTCs: A Private Trust Company Primer

As many families reevaluate their estate plans and fiduciary structures in the current environment, they often consider a private trust company (“PTC”). To assist in these discussions, we have created a PTC Primer, which can be found below or downloaded here. The Primer includes:

  • an overview of PTCs and how they operate
  • why PTCs may be preferable to the traditional trustee model
  • a diagram of a common PTC structure and Willow Street roles
  • the role and responsibilities of a PTC Board
  • the role and responsibilities of a PTC Secretary
  • elements of Wyoming situs

We hope this is helpful for you and your client families, and welcome the opportunity for further discussions about PTCs and other Wyoming-based fiduciary solutions.

An overview of Wyoming Private Trust Companies (PTC)

PTC Primer

The Private Trust Company allows client families to unbundle fiduciary services in furtherance of family and financial goals. Some states, including Wyoming, have authorized Private Trust Companies (“PTCs”). The PTC is a business entity organized to provide fiduciary services to a family, which is broadly defined to include multiple generations and branches of an individual family. The PTC combines the structure and benefits of a corporate trustee with the flexibility of allowing trusted advisors and family members to participate in PTC operation and trust governance, as appropriate and consistent with tax objectives. It also allows the family or its trusts to own the trust company that serves as trustee of its family trusts.

The PTC is operated by the family and its trusted advisors, often in conjunction with a family office and an administrative services provider (e.g., Willow Street Group). The PTC is managed by a Board of Directors, whose role is to provide oversight to the PTC. Investment activities are performed by an Investment Committee, comprised of family members and trusted advisors. Distribution activities are performed by a Distribution Committee, typically comprised of disinterested family members and trusted advisors. Administrative tasks are performed by a family office, the administrative services provider, or a combination thereof.

PTCs are often preferable to the traditional trustee model because they:

  • Allow the family to have more control over their fiduciary structures,
  • Separate the different tasks and allocate each to a party with the requisite expertise,
  • Decrease costs associated with traditional corporate trustees,
  • Allow the family to hold concentrated positions or non-traditional assets,
  • Limit liability for family members,
  • Increase efficiencies in decision-making and implementation,
  • Provide a liability shield for family members and trusted advisors serving in fiduciary roles,
  • Decrease trustee costs through economies of scale and lack of profit motivation, and
  • Facilitate family participation, beneficiary education, and collaboration with trusted advisors.

The following chart details the primary elements of the PTC structure.

Financial Oversight
  • Decisions relating to the PTC’s annual budget
  • Determination of the amount of Trustee fees that the PTC will charge underlying trusts
  • Tax reporting, in some instances; usually tax matters are handled by an accounting team, officers, and/or a family office, but sometimes the Board may wish to review and approve (or supervise) the preparation and filing of tax returns
  • Arrangement for periodic financial audits
Trustee and Service Provider Oversight
  • Decisions relating to acceptance of or resignation from trusteeships
  • Decisions relating to hiring and firing of third-party service providers, such as administrative, legal, or accounting advisors for the PTC and each underlying trust
