Source: FFIEC National Information Center relationships ↗. Rows are retained NIC relationships connected to institutions in the OptimaYield regulatory universe. They do not establish complete market ownership coverage, beneficial ownership, transaction intent, or current control when an end date is present.
The immutable archive contains 288,618 relationships and 183,852 distinct endpoint RSSD IDs. The product retains 18,771 relationships (6.5%). Dates and fields remain reported facts; OptimaYield does not infer control, beneficial ownership, acquisition intent, or completeness beyond this measurement.
