A more thorough explanation:

A registered public offering is a type of securities offering that is registered with the Securities and Exchange Commission (SEC) and appropriate state securities commissions. This means that the company issuing the securities has complied with all the necessary regulations and disclosures required by law.

• Initial Public Offering (IPO): This is a company's first public sale of stock. It is a type of registered public offering where the company offers its equity securities to the public through a registration statement.
• Rights Offering: This is an issue of stock-purchase rights allowing shareholders to buy newly issued stock at a fixed price, usually below market value, and in proportion to the number of shares they already own. It is a type of registered public offering because it is registered with the SEC and state securities commissions.
• Secondary Offering: This is any offering by an issuer of securities after its initial public offering. It is a type of registered public offering because it is registered with the SEC and state securities commissions.

These examples illustrate how a registered public offering is a type of securities offering that is registered with the SEC and state securities commissions. This ensures that the company issuing the securities has complied with all the necessary regulations and disclosures required by law.
