Understanding the maturity calendar

Where it stands today

$3.00T was due within 12 months of the month-end of 31 Mar 2015, 49.2% of it in bills.

What does the maturity calendar show?

Treasury usually pays maturing debt with new borrowing, so the amount due is the amount Treasury rolls over into new securities.

Bills issued after the month-end are not here; the calendar filled with new bills every week.
