For a more detailed description of how Zendesk calculates its dollar-based net expansion rate, please refer to Zendesk’s periodic reports ﬁled with the Securities and Exchange Commission. Zendesk’s percentage of annual recurring revenue that is generated by customer accounts with more than $250,000 in annual recurring revenue is determined by dividing the total annual recurring revenue from customer accounts with more than $250,000 in annual recurring revenue from our products other than Sell and Sunshine Conversations as of the measurement date by the total annual recurring revenue for all customer accounts from our products other than Sell and Sunshine Conversations as of the measurement date. Zendesk determines the customer accounts with $250,000 in annual recurring revenue as of the measurement date based on the annual recurring revenue of a customer account at the measurement date. A “customer account” is based on an identiﬁer tracked in our internal sales system as a separate and distinct buying entity. Zendesk determines its bookings as the incremental additional annual recurring revenue from contracts that were entered into during the referenced ﬁscal quarter. Zendesk determines its net bookings as bookings less any annual recurring revenue lost from contracts which have not been renewed or a decrease in the level of paid services with our solutions over the referenced ﬁscal quarter. Zendesk's annual revenue run rate is based on its revenue for the most recent applicable quarter. Zendesk annualizes such results to estimate its annual revenue run rate by multiplying the revenue for its most recent applicable quarter by four. Zendesk's annual revenue run rate is not a comprehensive statement of its ﬁnancial results for such period and should not be viewed as a substitute for full annual or interim ﬁnancial statements prepared in accordance with GAAP. In addition, Zendesk's revenue for the most recent applicable quarter or annual revenue run rate are not necessarily indicative of the results to be achieved in any future period. Zendesk determines its average deal size by dividing the annual recurring revenue from bookings for our products other than Sell and Sunshine Conversations in a quarter by the number of deals that were entered into during that quarter.
