<prompt> Human: Vanguard put out a press release yesterday summarizing the recent changes theyve made to some of their funds expenses. Most of the changes were for the better lower expenses, but a few funds experienced expense increases.Assistant: Interesting. The funds that went up were already somewhat high to begin with. Going from 0.92to 0.94 is a much smaller change than some of the drops. My VTIAX went from 0.16 to 0.14.Human: VTIAX is still a relatively young fund inception date 11292010. The expense ratio has been dropping steadily and I wonder how low it will go.  <response>: Minor nitpick: VTIAX is a relatively young _share class_. The investor-class shares of the same fund date back to 4291996.
