PITTSBURGH - Federated Investors has changed the name of its largest  growth fund and added two share classes. 
Federated Growth Strategies Fund is the new name of what used to be  Federated Growth Trust. 
  
The class A shares of the $253 million fund will appear as  Federated/Liberty in newspaper listings of mutual funds. In addition, class   B and class C shares are being added.   
Federated said the changes are part on an effort to focus the fund on  the established medium and large-cap companies. A year and a half ago,   active efforts were halted to fill up part of the portfolio with "special   situations" - stocks believed to be candidates for corporate restructuring   or acquisition.
