I buy a fair amount of individual corporate bonds. The comments above are both correct answers.
I might add that other data gleaned from this screenshot indicates the following:
* Min order to buy is 1, max is 6 (but this is the first time I have seen a "Call Us" comment, so this bond may have to be purchased with a phonecall, or at least the Vanguard bond desk folks want to explain other details to you about this offering).
* Moody's A3 rating, S&P rating of A- is an "upper medium investment grade" (fairly low risk)
Here is a complete rating chart:

* Callable bond (Altria can buy back at will).
* Very short term left (probably issued many years ago) Exp. Date is 11/10/2018, at which time the buyer will get face value (1 bond = $1000 face) back in their account and keep all accrued interest previously paid.
* Initial rate (9.700), pricing and YTM explained by others
If you want much more information on this or any bond, click on the brown colored "Altria Group Inc" line and a window will open with many more details.
This bond has very little life left. In general, interest rates (YTMs) improve if you purchase longer term bonds (not always). Rates (and risk !) are higher with lower quality bonds, so beware. It is a balancing act between payout, risk and duration.
