debt

An unlisted company can issue loan notes to the public. Loan notes are a form of debt instrument that can be issued by both listed and unlisted companies.

While listed companies have the option to issue shares through a public issue, unlisted companies may choose to raise funds by issuing loan notes to the public.
Loan notes are typically issued with a fixed interest rate and a maturity date, and they can be traded on the secondary market. This allows unlisted companies to access capital from a wider pool of investors.

I have told you several times now, that you need to take a relaxed view of the interpretation of facts.

I didn’t author the book but I can confirm again that “in principle, loan notes can be issued by any person, including any individual, company, partnership, association, trust or other entity”
