Abstract: Deferred revenue calculations can be necessary in an accrual-basis accounting model where a subscription or other type of sale is conducted that requires deferred revenue recognition. A snapshot state corresponding to the current state of a particular deferral can be generated. Out of order deferred events can also occur. The current state of the deferral can also be published in a downstream system.
