Underwriting

Underwriting is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Underwriting rather than just read about it. In short: Underwriting (UW) services are provided by some large financial institutions, such as banks, insurance companies and investment houses, whereby they guarantee payment in case of damage or financial loss and accept the financial risk for liability arising from such guarantee. An underwriting arrangement may be created in a number of situations including insurance, issues of security in a public offering, and bank len…

Key takeaways

  • Underwriting belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Underwriting to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Underwriting from memory before moving on to harder problems.

Reference excerpt

Underwriting (UW) services are provided by some large financial institutions, such as banks, insurance companies and investment houses, whereby they guarantee payment in case of damage or financial loss and accept the financial risk for liability arising from such guarantee. An underwriting arrangement may be created in a number of situations including insurance, issues of security in a public offering, and bank lending, among others. The person or institution that agrees to sell a minimum number of securities of the company for commission is called the underwriter.

History The term "underwriting" derives from the Lloyd's of London insurance market. Financial backers (or risk takers), who would accept some of the risk on a given venture (historically a sea voyage with associated risks of shipwreck) in exchange for a premium, would literally write their names under the risk information that was written on a Lloyd's slip created for this purpose.

Securities underwriting In the financial primary market, securities underwriting is the process by which investment banks raise investment capital from buyers on behalf of corporations and governments by issuing securities (such as stocks or bonds). As an underwriter, the investment bank guarantees a price for these securities, facilitates the issuance of the securities, and then sells them to the public (or retains them for their own proprietary account). This process is often seen in initial public offerings (IPOs), where investment banks help a corporation raise funds from the public. The underwriter is obligated to purchase the entire issue at a predetermined price before reselling the securities in the market. Should they not be able to find buyers, they will have to hold some securities themselves. To reduce the risk, they may form a syndicate with other investment banks. Each bank will buy a portion of the security issue, and typically resell securities from that portion to the public. Underwriters make their profit from the price difference (called "underwriting spread") between the price they pay the issuer and what they collect from buyers or from broker-dealers who buy portions of the offering. The services provided in the process of underwriting include:

Giving advice on whether to issue stocks or bonds, the timing of issuance (ideally, corporations should sell securities when they will obtain the highest possible price). Underwriters also have to determine at what price the security should be sold. Filing documents: assisting companies with making the filings required by financial authorities. Companies issuing new securities to the general public must file a registration statement detailing their financial conditions, management, competition, industry, experience, funding purposes, and securities' risk assessment. A portion of this statement is reproduced in a document called a prospectus, which investors can access to obtain information about new securities. Underwriting: A company sells the entire issue to the underwriter at an agreed price. The underwriter will then sell it to the public at a higher price to achieve a profit, to the extent that it does not retain part of the issue as a proprietary holding.

Risk, exclusivity, and reward Once the underwriting agreement is struck, the underwriter bears the risk of being unable to sell the underlying securities, and the cost of holding them on its books until such time in the future that they may be favorably sold. If the instrument is desirable, the underwriter and the securities issuer may choose to enter into an exclusivity agreement. In exchange for a higher price paid upfront to the issuer, or other favorable terms, the issuer may agree to make the underwriter the exclusive agent for the initial sale of the securities instrument. That is, even though third-party buyers might approach the issuer directly to buy, the issuer agrees to sell exclusively through the underwriter. In summary, the securities issuer gets cash up front, access to the contacts and sales channels of the underwriter, and is insulated from the market risk of being unable to sell the securities at a good price. The underwriter receives a profit from the markup, plus the possibility of an exclusive sales agreement. Also, if the securities are priced significantly below market price (as is often the custom), the underwriter also curries favor with powerful customers by granting them an immediate profit (see flipping), perhaps in a quid pro quo. This practice, which is typically justified as the reward for the underwriter for taking on the market risk, is occasionally criticized as unethical, such as the allegations that investment banker Frank Quattrone acted improperly in doling out hot IPO stock during the dot-com bubble. In an attempt to capture more of the value of their securities for themselves, issuing companies are increasingly turning to alternative vehicles for going public, such as direct listings and SPACs.

Bank underwriting In banking, underwriting is the detailed credit analysis preceding the granting of a loan, based on credit information furnished by the borrower; such underwriting falls into several areas:

Worked examples

Example 1 — a first encounter with Underwriting

Start with the simplest possible case. Write down what Underwriting claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Underwriting before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Underwriting ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Underwriting

In research
Underwriting appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Underwriting in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Underwriting is common in secondary-school and first-year university syllabi. It links to neighbouring topics Actuarial science, Securities (finance), Underwriting, so understanding it makes those chapters shorter.
In everyday life
Look for Underwriting outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
