Family Office Framework

There are many ways to structure a family office including creating your own in-house entity, outsourcing to a single service provide, or engaging various service providers. For most families the Virtual Family Office model is an effective framework, which involves the coordination of your internal administration with select tax, legal and investment professionals. This approach provides the flexibility to utilize those independent services most important to your needs and engage only those professionals that you feel comfortable advising your family.

Structural Considerations

There is no one-size-fits-all approach, as each family office has unique circumstances, priorities and sensitivities. Regardless of the structure, common approaches include:

  • Design to Suit Your Family Needs
  • Seek Flexibility, Control and Privacy
  • Focus, Expertise and Stability of Providers
  • Objectivity to Represent Your Best Interests
  • Coordinated Tax, Legal and Investment Planning
  • Tailor Generational Stewardship Messaging
  • Manage Your Philanthropic Endeavors
  • Efficient and Reasonable Cost Structure
  • Consolidated Reporting with Account and Data Aggregation

Discipline, Patience and Time

After your investment portfolio is designed and implemented, there exists the potential for market movements to affect investor behavior. This dynamic, called “behavioral finance”, is the emotional reaction and subsequent adjustments made to your portfolio during extreme market cycles, which can be detrimental to achieving your long term objectives and have can have a significant impact on your performance.

Investment Principles

  • Clearly Define Your Investment Objectives
  • Consider the Purpose, Risk and Return Parameters of the Various Asset Classes

  • Systematic Portfolio Rebalancing Can Avoid Emotional Reactions to Severe Market Conditions
  • Maintain a Long-Term Orientation
  • Recognize that Market Directions are Impossible to Predict
  • Don’t Let the Media Influence Decision Making
  • Time Allows a Strategy the Opportunity to Perform Over Time
