Stripped par is held as separate interest and principal components rather than as whole securities. The Safe Rate indices deliberately do not deduct it, and the whole-market figure is published so that decision can be argued with. Market statistics.
Amount outstanding as reported by Treasury, in its Monthly Statement of the Public Debt. The Safe Rate indices weight on a different figure, float-adjusted original par, and the two are not comparable security by security. The index figures are published per holding.

Yield and duration are withheld this close to maturity, not missing. Inside a month a Treasury trades on settlement mechanics rather than on yield, and its price is a rounding of par, annualizing a two-day stub produces a number in the tens of percent that would be arithmetically correct and completely misleading. The price, the residual and the key rate durations below are unaffected.

Sensitivity to a one basis point move at each point on the curve, in years. All of it sits at 3M. For a security with a single remaining cashflow that is the true shape, not missing data.
Against the fitted curve
Priced 0.60 cents per 100 of face rich to the curve on that day.
Shown as a price rather than a yield. This security was close enough to maturity that annualizing is meaningless, the same reason it carries no yield to maturity above, and the same difference quoted in basis points would read as an enormous mispricing rather than the few cents it is.

Prices are per 100 of face, from Treasury's own end-of-day file. A dash in the bid or offer column means none was posted that day.
Auction
A CUSIP can be auctioned more than once: Treasury reopens an existing security rather than issuing a new one, so the same bond is sold again at whatever yield the market then wants.
Index levels before September 30, 2026 are back-tested. They were computed after the fact by applying the rules to historical data, which benefits from hindsight in the choice of rules, and an index cannot be invested in directly. Methodology v1.0 takes effect at that rebalance, when levels begin to be struck on the day; the rulebook is identical either way, and the version is published on every row.
A fitted curve is a fit, not a quote. Daily error averages 3.8 basis points across the history and reaches about 20 on the worst days, in December 2008, when the market was genuinely hard to fit one smooth curve to. Every curve page publishes its own fit error rather than burying it.
