Scoring of resolution plans determines comparative ranking and permitted improvements under disclosed parameters and thresholds. Regulation 42 requires the committee to disclose a basis for evaluation in the invitation for resolution plans, specifying parameters, their application and any formulae to compute scores; it may also set minimum parameter thresholds that disqualify plans that do not meet them. The regulation defines significantly better as a committee approved absolute or percentage advantage in score, and prescribes a tick size as the minimum absolute or percentage improvement required for one plan to improve upon another, with illustrative calculations for each concept.
