My 401k options are basically all CITs through BlackRock (via Fidelity). While they are low cost (0.04% for the Target Date Funds), I dislike the lack of information about what I really own. The share class gets updated every couple years (normally dropping the ER) and poof, all the historical information is gone. And reading that one reason they tend to be lower cost is that they don't have SEC reporting requirements...well that's a weird thing. (This car is cheaper because we don't need to include safety features...these smoke alarms are cheaper because we don't have pay to certify them...and so on)
I tend to be somewhat trusting in these sorts of things (this is a large company with 60k+ employees), but when trying to sharpen the pencil to really understand something as simple as overall asset allocation I sometimes get a little uneasy. One thing I can confidently say, is that "they" are not using these CITs for my benefit, but rather because it makes the most business sense (meaning "they" make the most money from doing it this way).
Anybody with more insight or comments? I don't mind continuing to leave blinders on and let it go, just now and then I'd like to have more transparency. If it truly bugged me I do have Brokerage Link and could move to something with annual reports and a ticker.
