*'''[[Corporate action]] | *'''[[Corporate action]]s on {{eqderivprov|Issuer}}s''': (generally) benign but unscheduled matters of corporate structure concerning the management of specific underlying {{eqderivprov|Shares}}, that change the economic proposition represented by those {{eqderivprov|Shares}}, and not the [[equity derivative]] contract. So: {{eqderivprov|Merger Event}}s and {{eqderivprov|Tender Offer}}s; | ||
*'''[[Index Adjustment Event - Equity Derivatives Provision|Index adjustments]]''': Equivalent measures that relate to an underlying {{eqderivprov|Index}} - collectively {{eqderivprov|Index Adjustment Event}}s.

So, the {{eqderivprov|Triple Cocktail}} of {{eqderivprov|Change in Law}}, {{eqderivprov|Hedging Disruption}} and {{eqderivprov|Increased Cost of Hedging}}; the specific issues relating to short-selling ({{eqderivprov|Loss of Stock Borrow}} and {{eqderivprov|Increased Cost of Stock Borrow}}) and then two random ones that don’t brilliantly fit with this theory, and which people tend to disapply — possibly for that exact reason, but they are fairly well covered by the {{eqderivprov|Triple Cocktail}} anyway — {{eqderivprov|Failure to Deliver}} on account of illiquidity and, even more randomly, {{eqderivprov|Insolvency Filing}}<ref>especiaklly since there is already an {{eqderivprov|Insolvency}} event covering most of this). <br> |
