No-par stock is a term used in corporate finance to refer to stocks that do not have a nominal or par value attached to them. This means that the shares do not have a pre-determined value assigned to them, unlike stocks with fixed par values. Some synonyms for the term "no-par stock" include non-par stock, no-par value stock, or stock with no nominal value. These terms are commonly used interchangeably in the financial industry. No-par stock is often issued by companies to provide greater flexibility in pricing shares and to avoid legal restrictions on the issuance of low-priced stocks.
