Asset classification boundaries
Explains the ISA Verify service boundary for open-ended funds that appear on exchange venues, and why exchange trading alone does not turn a fund into an ordinary company share.
Published methodology & technical notes
HMRC ISA compliance library.
A client-facing index of Oppl’s published notes on ISA asset classification, recognised markets, exchange segments and the legal boundaries that sit behind an eligibility decision.
Why this library exists. ISA eligibility is rarely one data point. Security type, legal entity, exchange, market segment and the route through the HMRC rules can each alter the result. These notes document how Oppl approaches recurring areas of complexity.
