Which of the following is NOT a subtype of the Accrual Transaction Journal?

Points Expiration is not a subtype of the Accrual Transaction Journal because the journal is primarily focused on tracking membership-related transactions that affect point accrual and balance. The subtypes that do exist, such as Member Enrollment, Member Referral, and Member Cancellation, are all transactional events that contribute directly to the points accumulated or the status of a member's account within a loyalty program.

Member Enrollment represents the initial action where members join and start accumulating points. Member Referral tracks transactions resulting from a member referring new customers, which can also enhance earning potential. Member Cancellation pertains to the removal of a member from the program and the consequent point adjustments. In contrast, Points Expiration does not fit within the accrual transaction methodologies, as it pertains to the policy of how and when points are lost rather than the direct accrual of those points through member actions.
