Will my portfolio composition change as a result of the transfer?

Your account assets will be transferred to Betterment in-kind. Your Marcus Invest portfolio strategy will then be gradually transitioned to a similar Betterment portfolio strategy (described in “Portfolio Comparison”). For tax-advantaged accounts (e.g. IRAs), there will be no tax impact. For taxable accounts, Betterment will strive to make this update as tax-efficient as possible by using dividends, deposits, and transfers to help minimize tax impact, but the transition may result in some tax impact.
