6.3(a) “Market Disruption Event” means

(i) a material Trading Disruption or Exchange Disruption to a Share or Index during the hour before the Valuation Time (etc), or

(ii) an Early Closure.

When determining materiality of disruption for an index, a security's percentage contribution to an Index level will be based on its contribution to the overall level of the Index just before the Market Disruption Event happened.

To work out whether a Market Disruption Event exists for an entire Index as a result of a Market Disruption Event existing for one of its component securities Index, then that security's relevant percentage contribution to the Index will be based on a comparison of (x) the portion of the of the Index level attributable to that security and (y) the overall level of the Index, in each case immediately before the occurrence of such Market Disruption Event.
