When you make a Cash In to either of the funds (Versa Cash or Versa Cash-i), units are purchased from the respective funds.
Once your Cash In is reflected in your Versa account balance, you will start earning returns that are compounded. The accumulated returns will reflect in your balance whenever the unit price of the fund increases.
So, if you consistently make cash in through Versa over the long term, your money will constantly be reinvested to generate more returns.
