We are sharing an overview of Section 351 exchanges, which may be a consideration for certain investors seeking to reallocate equity portfolios in a tax-efficient manner. These strategies are subject to specific eligibility requirements and may not be appropriate in all circumstances. We encourage you to consult with your attorney/tax advisor to determine whether this is appropriate for you.

  • Tax-efficient reallocation tool: Section 351 exchanges allow appreciated equity holdings to be contributed into an ETF structure without triggering immediate capital gains, while maintaining the original tax basis.
  • Applicable use cases: This approach may be relevant for investors with concentrated positions or portfolios where tax considerations have limited the ability to rebalance or diversify.
  • Defined parameters: Participation is subject to eligibility, asset type restrictions, and diversification requirements (including 25%/50% thresholds), which must be met for the exchange to qualify.
  • Current considerations: Section 351 exchanges are increasingly being used in the context of broad equity exposure, including global mandates, as investors evaluate ways to adjust portfolio positioning without immediate tax recognition.
