The non-confidential summaries for return on investment and salary follow a similar pattern. These summaries include a table setting out information concerning developments in each injury factor in 2006, 2007, 2008, interim 2008, and interim 2009, in which percentage changes are wholly redacted. These summaries also include a trend line which displays "changes" in each injury factor over the POI. The tables and trend lines are followed by text describing the information in the tables.
