Yes.  My concern is that the organization is asked to "return resources
as required" (paragraph 5).  Is it adequate for the purpose of this
policy to assume that ARIN will include a list of the size of block(s)
expected/"required" to be returned as part of that communication?

and your parenthetical comment explains exactly why.  The org has more

[Dave Mohler] 
Well, I wasn't really making that assumption!! ;-)  I feel that the
policy is the place that ARIN and organizations look to for
communicating their respective responsibilities.  As such, explicitly
communicating that "If, after a reasonable time, the organization does
not..." or, perhaps even more clearly, "If, after three months, the
organization has not contacted ARIN to arrange for the return of..."
would help future readers of the policy to understand these

In looking back over the proposal with the benefit of these discussions,
I think I understand that the 6-month minimum clock essentially begins
when "ARIN [communicates] the results of the review to the
organization."  After that, it is up to the organization to return the
required amount of resources within the 6 months or demonstrate that
"good faith effort" toward returning those resources; otherwise ARIN can
unilaterally revoke its choice of the required amount of those

If this accurately reflects the intent of the policy, I believe I've
identified my core misunderstanding.  I interpreted "voluntarily return"
as being something that the organization recognizes their lack of
compliance with policy based on the review and of their own free will
offers back resources to bring them into compliance.  It appears that
the communication of results is more in terms of "This is how much you
must return within 6 months in order to come back into compliance;
develop and implement your own plan or we'll take what we need."  I'm
not arguing about the need for such a policy, just pointing out that the
phrase "voluntary return" led me (and could likely lead others) to
different assumptions about the policy's intent.

Am I now getting the essence of the policy accurately?
