OptionCorpActionRecordHist
Description
SpiderRock Option Corporate Action Record History captures OCC-issued corporate action adjustments affecting option contracts. Each record is keyed by the option root and the corporate action ex-date, and describes the contract adjustments applied on that date — including strike factor, multiplier changes, cash-on-exercise amounts, a free-text description, and the list of deliverable securities with their quantities and allocation percentages.
