Intro to the Insurance Industry
The insurance industry, while not particularly glamorous, offers steady and often highly profitable returns for long-term investors. Notably, Warren Buffett has harnessed this potential through his conglomerate, Berkshire Hathaway. One key to this success is the company’s use of insurance premiums or "float." Berkshire collects premiums from its policyholders and strategically invests this capital, paying out only a portion in claims. The magic here lies in their conservative underwriting practices, which minimize claim payouts, while the float continues to grow through ongoing premium collections. This free capital, if wisely invested, can lead to extraordinary long-term returns due to the power of compound growth.
But as straightforward as the insurance business may seem, assessing these companies requires a unique approach, different from how one might evaluate other sectors like retail or manufacturing. Insurance is not a one-size-fits-all industry, and understanding its nuances is crucial for investors.
Types of Insurance Companies
The insurance sector is quite diverse, encompassing various sub-industries that cater to specific needs:
1. Life Insurance: Provides a lump-sum payout to beneficiaries upon the policyholder's death.
2. Health Insurance: Covers medical expenses, personal injuries, and disability.
3. Property and Casualty Insurance: Protects against losses related to property damage and personal liability.
4. Auto Insurance: Covers costs associated with vehicle repair or replacement after accidents.
5. Reinsurance: Offers coverage to insurance companies themselves in the event of major, catastrophic losses.
While all these sectors share the fundamental business model of collecting premiums and paying out claims, the financial dynamics vary considerably between them. For example, health insurers expect to process claims for a majority of their customers, while property insurers might only receive claims from a small portion of their policyholders each year. Natural disasters, like Hurricane Milton, recently saw investors shy away from insurers with high exposure to affected regions, while companies less vulnerable benefited from share price gains. This volatility highlights the need for a careful, risk-adjusted approach when investing in insurance stocks.
The Dual Structure of Insurance: Underwriting and Investing
An insurance company generates profits in two distinct ways: through its underwriting operations and the investment of its float. Each of these plays an essential role in driving shareholder value.
1. The Art of Underwriting
In the insurance world, underwriting refers to the process of assessing risk, setting policy prices, and paying claims. To succeed in underwriting, insurers must carefully price their premiums to cover anticipated claims while still generating a profit. However, they also need to remain competitive with their pricing, as lower premiums can attract customers but increase the potential for excessive claims.
Underwriting success is often measured through three key ratios:
●Loss Ratio: This is calculated by dividing total claims paid by total premiums earned. It indicates how well the company manages risk and controls claims.
● Expense Ratio: This compares operating expenses to total premiums earned, reflecting the company’s operational efficiency.
●Combined Ratio: The sum of the loss and expense ratios, this key metric gives a comprehensive view of the company’s overall underwriting performance.
A combined ratio below 100% indicates that the company is making a profit from its underwriting activities. Investors should track these ratios over time, aiming for gradual improvement as the business scales. While high revenue growth might sound appealing, in the insurance industry, rapid growth can sometimes indicate that a company is underpricing its premiums, which can lead to higher claims and reduced profitability.
2. Investing the Float
The second major contributor to an insurer’s profits is the investment of its float. Float refers to the premiums collected from policyholders that have not yet been paid out in claims. Insurers usually invest these funds in a mix of fixed-income securities (like bonds) and, to a lesser extent, equities and other investments.
The goal is for the returns on these investments to enhance overall profitability, supplementing the profits from underwriting. Over time, retained earnings from these investment returns build up, providing a cushion that allows the company to absorb underwriting risks more effectively. A healthy insurance company will show a steady increase in its book value, which represents its equity (total assets minus liabilities).
For example, Progressive Corporation has demonstrated impressive equity growth over the past decade, expanding from $6 billion to $23 billion. Investors can track book value to assess a company’s financial health, and the price-to-book (P/B) ratio is a common valuation metric. Larger, more diversified insurers often trade at a premium P/B ratio due to their ability to spread risk across multiple markets, while smaller firms may offer more potential for growth but also come with heightened risk.
Fintech and the Rise of Non-Bank Lenders
While traditional insurance and banking remain dominant in the financial sector, financial technology (fintech) companies have been attempting to disrupt these industries for the past two decades. Payment giants like Visa and Mastercard are among the original fintech firms, and companies providing technology infrastructure for financial institutions have seen some success. However, many of the more speculative fintech players, such as Affirm, SoFi, and Upstart, have struggled to develop sustainable business models without relying on significant amounts of free capital.
In contrast, non-bank lenders have emerged as the real disruptors in the financial landscape. These companies, often backed by private equity, make loans without being subject to the same regulatory constraints as traditional banks. This trend has been accelerated by two factors: increased capital requirements for banks following the Global Financial Crisis and the rise of private credit funds.
Private credit has grown significantly in recent years, especially in the U.S., where it is now a major part of the lending ecosystem. Large firms like Apollo Global Management have ambitious plans to expand their lending activities, potentially outpacing traditional banks in the near future. While this shift brings some concerns about systemic risk, it also presents opportunities for fintech firms to partner with these new lenders and provide enhanced customer experiences.
The insurance industry, though often overlooked, offers substantial opportunities for both profit and growth. Successful insurers carefully manage their underwriting operations while leveraging their float for investment returns. Investors who understand the key metrics—such as loss, expense, and combined ratios—can make informed decisions and potentially achieve significant long-term gains. At the same time, the rise of non-bank lending and the ongoing evolution of fintech signal that the financial landscape will continue to change, providing both risks and rewards for those paying close attention.
