Ar ôl trafod y mater ymhellach, mae'r gweinyddiaethau wedi cytuno:gadarnhau eu hymrwymiad i sicrhau llwyddiant Gêmau Olympaidd 2012 a digwyddiadau chwaraeon mawr eraill yn y DU;gadarnhau eu hymrwymiad i gyfathrebu, cydweithio'n agos a pharchu ei gilydd er mwyn osgoi a datrys anghydfodau, a defnyddio protocol y Cyd-bwyllgor Gweinidogion i ddatrys anghydfodau fel y nodir yn y Memorandwm Cyd-ddealltwriaeth rhwng Llywodraeth y DU a'r gweinyddiaethau datganoledig;ar bwysigrwydd dysgu gwersi o bob anghydfod er mwyn eu gwneud yn llai tebygol o godi yn y dyfodol. Yn yr achos hwn, nodwyd y cytundeb yn ystod trafodaethau cynharach yr anghydfod hwn y dylai penderfyniadau ar fformiwla Barnett fod bob amser yn seiliedig ar dystiolaeth a chael eu gwneud mewn modd amserol ac mewn ymgynghoriad â'r gweinyddiaethau datganoledig. Cytunwyd ar y geiriad o'r blaen ac erbyn hyn mae wedi'i gynnwys ym Mholisi Datganiad Cyllid Trysorlys Ei Mawrhydi a gyhoeddwyd ochr yn ochr ag Adolygiad y DU o Wariant yn hydref 2010;bod newidiadau sylweddol wedi bod mewn cyllid cyhoeddus ers i'r anghydfod hwn godi yn y lle cyntaf ac na ddylent, felly, ailystyried penderfyniadau ar gyllideb y Gêmau Olympaidd a wnaeth Llywodraeth flaenorol y DU;y bydd Llywodraeth Cymru, Llywodraeth yr Alban a Gweithrediaeth Gogledd Iwerddon yn derbyn swm untro sy'n gyfartal â symiau canlyniadol Barnett ar gyfer newidiadau i gyllid y Gêmau Olympaidd ers i Lywodraeth bresennol y DU ddod i rym ym mis Mai 2010. £30.2 miliwn yw cyfanswm y symiau hyn, a bydd Llywodraeth Cymru yn derbyn £8.9 miliwn ohono, Llywodraeth yr Alban £16 miliwn a Gweithrediaeth Gogledd Iwerddon £5.4 miliwn (wedi'i dalgrynnu i'r £100,000 agosaf). Caiff y symiau hyn eu hychwanegu at gyllidebau'r gweinyddiaethau datganoledig a byddant ar gael i'w gwario yn 2011-12;ar bwysigrwydd adolygu'n fanwl gostau a buddiannau Gêmau Olympaidd 2012 a digwyddiadau chwaraeon mawr eraill yn y DU, a pha mor bwysig ydyw i'r Llywodraethau gydweithio ar yr astudiaethau hynny a'u rhannu.
Following further consideration, the administrations have now agreed:to reaffirm their shared commitment to the success of the 2012 Olympics and other major sporting events in the UK;to reaffirm their shared commitment to the principles of good communication, close cooperation and mutual respect as the means of avoiding and resolving disputes, and to the use and benefit of the JMC’s dispute-resolution protocol as set out in the Memorandum of Understanding between the UK Government and the devolved administrations;the importance of learning lessons from all disputes in order to make them less likely to arise in the future.  In this instance, they noted the agreement reached in earlier discussions of this dispute that decisions on the application of the Barnett formula should “always be evidence based, be undertaken in a timely manner and in consultation with the devolved administrations”.  This wording was agreed previously and is now included in HM Treasury’s Statement of Funding Policy which was published alongside the UK Spending Review in autumn 2010;that there have been significant changes in public finances since this dispute first arose and that they should therefore not revisit decisions on the Olympics budget first made by the previous UK Government;that the Welsh Government, the Scottish Government and the Northern Ireland Executive will receive a one-off sum equivalent to the Barnett consequentials of relevant changes to Olympics funding since the present UK Government took office in May 2010.  These sums amount to £30.2m, of which the Welsh Government will receive £8.9m, the Scottish Government £16m and the Northern Ireland Executive £5.4m (rounded to the nearest £100,000).  These sums will be added to the budgets of the devolved administrations so as to be available for spending in 2011-12; andthe importance, firstly, of reviewing thoroughly the costs and benefits of the 2012 Olympic Games and other major sporting events in the UK and, secondly, of Governments co-operating on and sharing such studies.
