This gives us an indication of the revenue that can be earned in the following 12-month period from our existing client base assuming no cancellations or price changes occur during that period. Subscription revenue excludes any non-recurring revenue, which has been insignificant to date. Revenue Retention Rate is the actual subscription revenue (dollar-based) recognized over a 12-month period from customers that were clients on the day prior to the start of such 12-month period, divided by our Annualized Recurring Revenue as of the day prior to the start of the 12-month period.
