Status is granted for the remainder of the current membership year in which it is earned, and a full year after.. thus ensuring every member gets at least 12 months of status, and if one works it right maybe 23 months.
So in the example if one's anniversary date is June (Joined in June 2018), then earns status in October, they'd hold that status through to June 30, 2020 (unless they requalify during the July 19-June 20 period of course).
