The OCC Equities Special Settlements dataset is derived from official Options Clearing Corporation records and provides authoritative coverage of non-standard (adjusted) U.S. equity option contracts resulting from corporate actions such as mergers, splits, spin-offs, or special dividends.The dataset includes key identifiers such as the adjusted option symbol and underlying equity symbol, along with detailed settlement mechanics describing how exercise and assignment obligations were resolved. This includes information on delivery components, enabling users to accurately interpret post-adjustment contract terms and cash-and-carry outcomes. Data is available on a daily basis starting November 1, 2017, and is designed to support historical research, back-testing, compliance validation, and institutional-grade options analytics involving complex or non-standard contracts.
