A Z-Share is a type of mutual fund share class that provides lower management fees for the investors. It's named "Z-Share" because it was originally the last letter in the alphabet and used to indicate that it was the last or lower-priced share class of a mutual fund.In general, Z-Shares are similar to other share classes in terms of their investment objectives and holdings, but they usually have lower expense ratios compared to A-Shares and other share classes. This lower cost can be attractive to cost-conscious investors, but it often comes with restrictions on early redemption, higher minimum investment amounts, and limitations on how the shares can be purchased or sold.It's important to understand that Z-Shares are not the same as every other fund and to carefully review the terms and conditions of a Z-Share before making an investment. It's always a good idea to consult with a financial advisor to help determine if a Z-Share is the right investment for you, given your investment goals and risk tolerance.
