Hi Ryan - I'm not sure I understand your question. The performance period is basically defined by the timing of your submittal. If you submit documentation, your PP effectively ends at that time. There is no need for your policy to state the performance period - what is important is that the policy state the date of adoption and the next date of revision or review. The latter date can be as distant in the future as you prefer, or it may simply be 'when necessary.' Does that help at all?
