## Why is there no Clarity Score for I.o.o. Limited yet?

The Clarity Score is computed from full financial filing history. I.o.o. Limited is on the official
register but outside the detailed-filing group we currently score (or awaiting its first filings), so
we show its official register record instead of a rating. A rating can be added when the charity enters
our scoring dataset with enough filing data. Payment never influences a rating.

## What should you check before donating to I.o.o. Limited?

- Match the registered name and number to the appeal. A real charity number can be copied by someone impersonating the organisation.
- Open the current register entry to check status, contact details and available accounts. This profile reflects a dated extract.
- Read the charity’s annual report for its work and results. An unrated profile means we lack a full assessment; it is not a negative rating.
