2. §2Otherwise, this market will resolve to “No”.
3. §3The deal must be a publicly announced mutual agreement or otherwise confirmed by an overwhelming consensus of credible reporting.

5. §5Only territory ceded as part of a diplomatic process or agreement will qualify.
6. §6If a territorial adjustment is made as part of a mutual border demarcation process or technical boundary agreement that does not materially alter de facto control or reflect a broader territorial concession, it will not qualify for a 'Yes' resolution unless it is reported as a territorial concession by a consensus of credible reporting.
7. §7Any agreement which cedes de facto military control of territory held by Ukraine will qualify regardless of whether Ukraine formally maintains its claim to sovereignty.
