Vanguard has upgraded one of my funds from investor to admiral share status. They did this because my assets in this fund now qualify for a lower expense ratio. However the symbol has changed and the new share price is different. ( approx 2.1 x the investor share price) Because this is simply a change in share status there is no taxable event.
If the share prices were identical I would simply edit the investment to change the symbol. If I treat this as a new investment there is no continuity of tax basis.
What is the best way to deal with this in FM? I sense there is a very simple solution but I cannot see it.
