The Tax Efficiency feature focuses on the strategic structuring of the VA ETF (Variable Annuity Exchange-Traded Fund) to optimize tax outcomes for clients. This involves leveraging specific tax benefits associated with ETFs, such as the ability to defer taxes on capital gains until the investment is sold, and utilizing in-kind transfers to minimize taxable events. By implementing this feature, clients can potentially enhance their after-tax returns, making the investment more attractive and competitive in the market.
