The new risk outlook year starts at the end of July. For example, all risk reports written in August 2022 use the forecast risk year 2023. Risk Score calculations are based on an 11-year underlying reference period. As the outlook year rolls forward, so does the reference period. Coinciding with this structural change, we provide an annual rollover analysis to assist in implementing changes.
