Thanks for the responses. I do understand CITs, but am not sure why I should trust them. Why is this a non-issue for this fund?
I could rearrange some other assets in other accounts and use the Vanguard Total Intl Stock Indx Admiral. There are no other index-type funds in the 401k options and I like to KISS. My best other index option is the WF/BlackRock US Agregg Bond Index CIT N, but I would have the same trust issues with that. The rest are mostly Target date funds and smaller niche funds that I prefer not to use.
