Beginning with the invoices due in January 2008, due dates for all ARIN renewal invoices will shift to the last day of the month in which an organization's anniversary occurs. This includes renewals for all IP address resources, ASNs, and registration transfers. The anniversary date for an organization is the date when its first resource registration from ARIN was completed. With this change, the month of the anniversary date will be the only factor for determining when invoices will be due. This should simplify accounting for customer organizations.
