Significant events
- “At the start of the year in America we had two incidents which unfortunately led to two fatalities. These incidents lead to a change in our cleaning policies and process. This also led to a temporary loss of revenue while operations stopped and new ways of working put in place. The change in practice also meant we incurred additional cost in this type of close entry cleaning.”

Each % is (latest − prior) ÷ |prior| for the line item as filed. Periods don't have to be exactly 12 months apart — a long or short period (typical around incorporation or year-end changes) will distort the comparison. Lines a company doesn't report are omitted. About these numbers
