Therramus, I think you'll want to read this previous thread on the same subject:

Be sure you read the entire thread, because I made an erronious statement in the OP which is corrected further on. I want to remind you that all mutual funds are required to have their stocks and other investments held by a custody agent. We own the stocks in a mutual fund, not the company that runs the mutual fund. Our stocks cannot be used to cover the debts or obligations of the mutual fund company.
We are certainly exposed to any decline in the many stocks and bonds we may have in our mutual funds; That's why we bought the mutual funds.
But the failure of an investment company is not as catastrophic to the customers as would be the failure of an annuity-issuing insurance company. And, I might add, our (non-TIAA Traditional) annuities at TIAA-CREF are backed by the investments in the CREF accounts/TIAA Real Estate Account. Like those in a mutual fund, they are OURS, not CREF's. And they are held at a custody agent.
You are right to be concerned, but wrong to be frightened. It says right on the inside cover of the CREF prospectus "...not guaranteed by the FDIC or any other government agency." This is not a secret. But it's also not a secret, if you keep all your retirement money in a bank, you will be eating cat food during your retirement.

Edit: To change the subject to AIG for a moment, consider that AIG had to mark down its portfolio of credit default swaps by $25 billion. Never mind which B.S.D.- Masters of the Universe there were stupid enough to write them. The point is that TIAA has never been in the credit swap writing business. So they'll never have to write them down, or post another $18 billion in collateral (AIG again). Sometimes it's good to do business with a company that's never in the news ...
