per 100: the coupon earned since the last payment on 15 Aug 2026
the price plus accrued interest: what a buyer pays at settlement
years: the average time to its payments, weighted by their present value
how the duration itself changes as the yield moves
per 100: how much the price moves for a 0.01-point move in yield (DV01)
These come from a model, not from a market: the Treasury's par curve of 2 Oct 2026, turned into a discount factor for each payment of this security. They can differ from the price at which it trades, and the yield to maturity is what holding it to the end would earn if every payment arrives, at this estimated price. It is not a return anyone is owed: a different price, a sale before maturity or reinvesting at other rates all change what is actually earned.
The auctions
The Treasury sells each security at auction. The first auction issues it; later ones, called reopenings, sell more of the same security.
| Auction | Kind | Offered | Accepted | Bid-to-cover | High yield |
|---|---|---|---|---|---|
| 14 Apr 2011 | Reopening | $13.0B | $13.6B | 2.83 | 4.531% |
| 10 Mar 2011 | Reopening | $13.0B | $13.0B | 3.02 | 4.569% |
| 10 Feb 2011 | New issue | $16.0B | $16.4B | 2.51 | 4.750% |
Bid-to-cover is the amount bid divided by the amount sold: 2.5 means bids for two and a half times what was sold. The high yield is the highest yield at which the Treasury accepted bids.
