ARIN IP6 policy for those with legacy IP4 Space

Was looking at the ARIN IP6 policy and cannot find any reference to those who have IP4 legacy space. Isn't there an automatic allocation for those of us who have legacy IP space. If not, is ARIN saying we have to pay them a fee to use IP6? Isn't this a disincentive for us to move up to IP6? Those with legacy IP4 space should have the equivalent IP6 space under the same terms. Or am I missing something?
