Underwriting in Investment Banking: Investment bankers play an important role in underwriting, a key part of the financial system. Underwriting means taking on financial risk to help companies raise money by issuing stocks or bonds. It is especially important because it connects businesses with investors while managing the risks involved.

When a company wants to launch an IPO (Initial Public Offering), investment bankers act as underwriters. They help set the right price for the shares, buy the securities from the company, and then sell them to the public. This gives the company access to funds and gives investors confidence in the deal.

Underwriting supports trust in the market by ensuring fair pricing and reducing risk. It also keeps financial markets stable and working smoothly. Learn more about underwriting, types, how underwriting works, importance of underwriting in investment banking, and more below.

What is Underwriting?

Underwriting is the process where a person or company checks and takes on financial risk in return for a fee. This risk is usually related to loans, insurance, or investment securities. The word “underwriting” comes from an old practice where people would sign under the amount of risk they agreed to take.

In today’s financial world, underwriting helps set the right price for different risks. For example:

  • In insurance, underwriters look at age, health, and lifestyle to decide the coverage and premium.

  • In loans, they review income, credit score, and assets to approve or reject the loan.

  • In investment banking, underwriting happens during IPOs, where banks buy shares from companies and sell them to investors.

Underwriting is important because it helps keep the financial system stable by making sure risks are well understood and managed.

Types of Underwriting in Investment Banking

Investment bankers have different types of underwriting that states how the risk will be considered and how capital will be raised. The purpose of each method is to assist companies to raise the money but with confidence of investors. The key types of underwriting are the following:

1. Firm Commitment Underwriting

Under this type, the investment bank will make an agreement to buy the full issue of the shares or bonds with the company and distribute them to the market. When not all the securities are able to reach a buyer, the bank incurs the loss. This provides the company with assurance that it would be able to get the entire capital that it requires.

2. Best Efforts Underwriting

Here, the bank promises to try its best to sell the securities but does not guarantee the full sale. Any unsold shares are returned to the company. This reduces risk for the bank but also means the company may not raise the full amount it expects.

3. All-or-None Underwriting

In this case, the offering is completed only if all the securities are sold. If not, the entire deal is canceled. This protects the company from receiving only part of the funds, ensuring the project or plan is fully funded or not started at all.

4. Syndicate Underwriting

In case of more complex or large deals, a number of investment banks join hands to constitute what is known as a syndicate. They sell the securities in a group and share the risk amongst themselves. This process gives us the capacity to reach a broader market area and less strain on an individual bank.

5. Standby Underwriting

It is widely common in rights issues. The bank is ready to acquire any shares that will not be purchased by the existing shareholders. This will ensure that the company will be able to raise intended capital even in case some shareholders fail to do it.

How Underwriting Works?

Underwriting refers to how financial institutions, like banks or insurance companies, assess and accept responsibility in this regard at a fee. It helps in ensuring that risks are rated properly and priced correctly in sectors such as banking sector, insurance and investments markets. The process of how underwriting works is as follows:

1. Risk Assessment: Underwriters will initially consider market performance, the financial wellness of an applicant and the amount of holdings. It is used in investment banking in the provision of a picture of how financially firm any company is and its future and subsequently selling some security, for example issuing of stocks or bonds.

2. Due Diligence: This step includes a thorough research. Underwriters research on the financial statements of the applicant, investigate the lawfulness, and predict the product demand in the market. Such research assists in the establishment of the right price of the securities or the premiums.

3. Prices and conditions: Risk analysis assumes that the prices of the securities (in the instance of securities offered during the IPO) or the bidding of the insurance, is calculated with the assistance of the underwriters. They also identify the conditions or the terms under which the investment or the covering takes place to create a platform where both parties are on the same page.

4. Risk acceptance or rejection: An underwriter is the person who accepts the risk and underwrites the contract in case it is acceptable. They can refuse the contract or renegotiate it to avert risks in instance the contract is with a high risk.

5. Distribution and Control: Once issued, the securities are offered to investors. In investment banking, the underwriter will keep track of how these securities are doing and will act to stabilize the prices.

Importance of Underwriting in Investment Banking

Underwriting is the most important role in investment banking, whereby the profits are made when companies, governments, and institutions combine to bring money in the form of loans and stocks. It makes sure that the securities are issued and allocated efficiently, which promotes stability in the markets as well as economic growth.

  • Capital Raising: Underwriting allows issuers to raise capital in both equities (IPOs) and debt (bonds) as, by taking on the risk of purchasing and reselling the securities, it sells securities at prices that will guarantee that capital is raised despite market volatility.

  • Market Stability: Underwriters calculate the market environment and the credibility of the issuer, and securities are sold at respective prices. This decreases riskiness and activity and increases investor certainty, particularly when there is an IPO or a large bond issue.

  • Risk Management: Underwriting implies extensive research of the underwriter of the offering on whether the issuer has a good financial position and the viability of the offering, safeguarding the investors and ensuring market integrity.

  • Price Stabilization: After securities are issued, underwriters may stabilize prices to prevent sharp declines, maintaining market trust and ensuring successful placements.

  • Regulatory Compliance: Investment banks ensure all disclosures meet legal standards, enhancing credibility and attracting institutional investors.

Underwriting in Investment Banking Example

In investment banking, underwriting helps companies raise capital by issuing securities. The process during an Initial Public Offering (IPO) can be understood through the following example:

Company AB’s IPO

  • Issuer: Company AB wants to raise ₹500 crore by issuing shares to the public.

  • Investment Bank: FG Investment Bank is hired to underwrite the IPO.

Underwriting Process:

  1. Due Diligence: FG Investment Bank conducts a thorough analysis of Company AB’s financial health, market position, and growth potential.

  2. Underwriting Agreement: FG agrees to purchase all the shares from Company AB and resell them to the public. This is known as firm commitment underwriting, where the bank assumes the full risk of the offering.

  3. Pricing: After evaluating market conditions and Company AB’s valuation, FG sets the IPO price at ₹250 per share.

  4. Marketing and Distribution: FG promotes the IPO to potential investors through roadshows, presentations, and marketing materials to generate interest in the offering.

  5. Risk Assumption: If the IPO does not sell all of the shares, FG absorbs the loss by holding any unsold shares.

  6. Post-Issue Stabilization: To stabilize the price if it falls below the IPO level, FG may buy back shares temporarily to ensure smooth trading in the secondary market.

This example shows underwriting’s role in bringing issuers and investors together, controlling financial risks, and ensuring the capital raising effort is a success.
