How to read these figures

Labels and displayed flow values are reported filing values or exact disclosed subtotals.

Labels and narrative explain the filing. A category marked “arithmetic bridge” or “residual” is calculated from reported totals, rather than a separately reported line.

Values are in millions of USD unless otherwise noted.
