Underwriter

What Is an Underwriter?

An underwriter is a financial firm, usually an investment bank, that helps a company or government sell new securities to the public. The underwriter acts as an intermediary between the issuer and investors. It advises on pricing and timing, helps prepare the offering documents, and manages the sale. The word also has a separate meaning in insurance, where an underwriter evaluates applicants and decides which risks to accept. In financial markets, it usually refers to the securities role.

How Underwriting Works

When a company plans an initial public offering (IPO), it typically hires one or more underwriters. The lead underwriter often forms a group called a syndicate, in which other banks share the work and the risk. The underwriters help prepare a prospectus, a document that describes the company's business and finances. They then set an offering price, often based on demand gathered from large institutional investors during a marketing period known as book-building.

For their services, underwriters earn an underwriting spread, which is the difference between the price they pay the issuer for the shares and the price at which the shares are sold to investors.

Firm Commitment and Best-Efforts Deals

Underwriting agreements generally take one of two forms. In a firm commitment, the underwriter buys the entire offering from the issuer and resells it, so the underwriter carries the risk if some shares go unsold. In a best-efforts arrangement, the underwriter agrees only to make a reasonable effort to sell the securities and does not guarantee the proceeds. Firm commitment is a common structure for many IPOs.

Underwriters in Insurance and Why It Matters

In insurance, an underwriter reviews an application, assesses the likelihood of a claim, and decides whether to offer coverage and at what premium. Investors may encounter the term in both settings when reading company reports.

For individual investors, the underwriter's involvement can offer clues about how a new offering was marketed and priced. Underwriters are paid by the issuer, which is one reason readers of a new offering's documents may look closely at the disclosed terms and risks. The first-day trading price of a new issue can also differ substantially from its offering price.
