Issue: a reopening re-auctions an existing security (same CUSIP), the norm for coupons outside refunding months; "New" sets a fresh coupon. Offered: the announced offering amount, what the Treasury put up for sale at that auction. Tail: the high yield minus the when-issued yield at the bid deadline, in basis points. Positive means the auction had to concede yield to clear, negative means it stopped through. A dash means no tail exists or none was captured: bills never have one (they price off a discount rate, with no when-issued market), and rows before desk coverage began in July 2026 predate tail capture — the official records publish no when-issued yield at all. Desk recap: the desk's live verdict, posted the moment results cross.
