Andersen Announces Closing of its Initial Public Offering and Full Exercise of the Underwriters’ Over-Allotment Option

Key Terms

initial public offering financial

An initial public offering (IPO) is when a private company first sells its shares to the public and becomes a stock-listed company. It matters because it allows the company to raise money from a wide range of investors, helping it grow, while giving early shareholders a way to sell some of their ownership.

over-allotment option financial

An over-allotment option is a special agreement that allows underwriters to sell more shares than initially planned if demand is high. Think of it like a retailer offering extra units of a popular product to meet additional customer interest. This option helps ensure the full sale is completed and can also give investors extra shares if they want more.

registration statement regulatory

A registration statement is a formal document that companies file with a government agency to offer new shares of stock to the public. It provides essential information about the company's finances, operations, and risks, helping investors make informed decisions. Think of it as a detailed product description that ensures transparency and trust before buying into a company.

Securities and Exchange Commission regulatory

A national government agency that enforces rules for buying, selling and disclosing information about stocks and other investments, acting like a referee and scorekeeper for financial markets. It requires companies to share clear, regular financial and business information and investigates fraud or rule-breaking, which matters to investors because those rules and disclosures help ensure fair prices, reduce hidden risks and make it easier to compare investment choices.

prospectus regulatory

A prospectus is a detailed document that explains a company's plans for offering new shares or investments to the public. It’s important because it provides potential investors with key information about the company’s business, risks, and how they might make money, helping them decide whether to invest. Think of it as a guidebook for understanding what you're buying into.

book-running managers financial

Book-running managers are the main banks or financial firms that organize and oversee a company's sale of new stocks or bonds. They help set the price, decide how many to sell, and coordinate the process to make sure everything runs smoothly. Their role is important because they guide the company through the complex process of raising money from investors.
