<prompt> Human: For the past year or so Ive had been investing in Vanguard Target Retirement 2055 Fund with a ticker symbol of VFFVX. Recently, that fund in my 401k changed to VAN TARGET RET 2055 TR I. The Vanguard Target Retirement 2055 Fund is no longer an option. Can anyone tell me the difference between the two? I cant find much information on the new fund. There seems to be no ticker symbol for the new VAN TARGET RET 2055 TR I fund, although the share price is in the 50s as opposed to the 30s for prior fund. I also cant tell if distributions are provided in the new fund.  <response>: If I had to guess, your plans investment advisor changed the share class for what ever reason. From the investor share class to Target Retirement 2055 Trust I. Find out if your plan has advisor attached and call them for details.
