RIPE, revenue 38M EUR (40M USD), members 20k = 2 k/member

ARIN, revenue 25M USD, members 25k = 1 k/member

APNIC, revenue 33M AUD (21M USD), members 10k = 2 k/member

LACNIC, revenue 10M USD, members 12k = 0.8 k/member

AFRINIC, revenue 6M USD, members 2k = 3 k/member

Thanks for the numbers Kaj. BTW I wonder how it was possible for two of five organisations listed, including RIPE, to not allocate the funds for a purchase of a regular SSL certificate for their resources, using instead free-tier CA (and RIPE uses the worst one in terms of hijack-ability, Let's Encrypt).
