A more thorough explanation:

A single-name paper is a type of negotiable instrument that is signed by only one person or entity, and is not guaranteed by a third party. This means that the maker of the instrument is solely responsible for its payment.

For example, a promissory note issued by a company that is not guaranteed by a bank or other financial institution would be considered a single-name paper. Another example would be a bond issued by an individual, rather than a corporation or government entity.

These examples illustrate the definition of single-name paper because they both involve a single maker who is solely responsible for the payment of the instrument. There is no third party guaranteeing the payment, which means that the holder of the instrument is relying solely on the creditworthiness of the maker.
