NotACPA said: Last fall, Fidelity decided to compress the number of funds that they offered ... and convert multiple classes of a fund into another fund. I used the "Mutual Fund Conversion" tool for this.BUT, as you've already discovered, it only converts all shares of the fund.What it actually records, however, is a "Removed" transaction followed by an "Added" transaction and on the Removed action, you can specify the 300 shares. On the Added, you can specify the cost basis of the new shares.
