The loss table, version 1.1.

The one programme that publishes a complete, structured loss table. Reversal and invalidation columns are negative in the workbook; magnitudes are used. Who bore the loss is read from the workbook's own two retirement columns: buffer pool retired, and retired for intentional reversal, which the operator replaces. No loss by vintage: 34 of the 41 loss rows carry no vintage and no issuance, because reversals are booked on their own rows, so the stratum is not derivable from this file and is not approximated.

Relinquishment under a statutory notice or voluntarily; the operator replaces the units. Twenty-one projects, 258,848 units, dated from the register's own notes for twenty of them.

Cumulative project stocks: the database records reversals covered by a buffer pool and reversals not covered, per project, with no date and no cause. The denominator is the database's own issued total. Coverage is the database's universe, not the market's, and its reversal columns are compiled by the database rather than taken directly from registry records; Verra publishes no buffer ledger of its own. Where those columns are zero for every project of a registry (Gold Standard, ART, Isometric) the registry's rows read not estimable rather than zero, because the database cannot tell a registry that had no reversal from one whose reversals it does not compile. Country strata under 25 projects are omitted as noise; they are in the download.

Cancellation transactions with the cause not stated on any row. A cancellation can be a reversal, an administrative correction or a compliance conversion, so this is a candidate rate and never a loss rate; it is here so the ceiling on what the derivative could hold is visible with its denominator.
