In a historic move, Berkshire Hathaway has acquired the esteemed Alleghany Corporation, catapulting its insurance float to a staggering $164 billion. This deal not only cements Berkshire Hathaway's position as a titan in the insurance industry, but also highlights the importance of the insurance float in the company's overall business strategy. In this article, we will delve into the nuances of this acquisition, its implications for Berkshire Hathaway, and the role of insurance float in shaping the company's trajectory.

This article is strongly based on Warren Buffett's letter to shareholders 2022.


In order to appreciate the magnitude of this deal, we must first take a step back and explore the origins of Berkshire Hathaway's foray into the insurance sector. It all began in 1967 when Berkshire purchased its first property-casualty insurer, a modest operation with a float of just $20,000. Since then, the company has embarked on a remarkable journey, growing its insurance float 8,000-fold through strategic acquisitions, operational excellence, and innovative business practices.

Alleghany Corporation, the latest addition to Berkshire Hathaway's insurance empire, is no stranger to the world of property-casualty insurance. Under the astute leadership of Joe Brandon, a seasoned insurance veteran with a deep understanding of both Berkshire Hathaway and the insurance industry, Alleghany Corporation has become a formidable force in its own right.

The Deal

The acquisition of Alleghany Corporation has significantly bolstered Berkshire Hathaway's insurance float, which now stands at an impressive $164 billion, up from $147 billion prior to the deal. This move not only underscores Berkshire's commitment to dominating the insurance space, but also brings Joe Brandon back into the Berkshirefold – a reunion that is poised to generate synergies between the two companies and unlock new growth opportunities.

Joe Brandon's expertise and familiarity with Berkshire Hathaway's culture and insurance operations make him the perfect candidate to helm this newly integrated entity. His past work with Berkshire has demonstrated a keen understanding of the company's unique approach to underwriting and investing, and this knowledge is expected to contribute to a seamless integration of Alleghany Corporation into the Berkshire Hathaway family.

One of the key advantages Berkshire Hathaway enjoys over its competitors is its unmatched financial strength, which allows its insurance subsidiaries to pursue valuable and enduring investment strategies that are simply unavailable to most other players in the market. This acquisition further solidifies Berkshire's position in the insurance landscape, granting them even greater access to resources and opportunities for growth.

The Importance of Insurance Float

For those unfamiliar with the term, "insurance float" refers to the pool of money generated by premiums collected from policyholders that has not yet been paid out in claims. This pool of capital is essentially an interest-free loan, enabling insurance companies like Berkshire Hathaway to invest the funds and generate returns.

Berkshire Hathaway's remarkable growth in insurance float, from a modest $20,000 in 1967 to a staggering $164 billion today, has been a cornerstone of its success. The company's ability to access and manage this enormous pool of capital has afforded it the flexibility to pursue unique and lucrative investment strategies that set it apart from its competitors.

Through a combination of strategic acquisitions, operational improvements, and innovative approaches to underwriting and risk management, Berkshire Hathaway has consistently grown its insurance float, providing the company with a powerful financial engine that fuels its ongoing success.

The Value of Float in Berkshire's Financial Statements

Interestingly, insurance float is not recognized as an asset in financial statements, despite its extraordinary value to companies like Berkshire Hathaway. This is primarily because insurance float represents a liability, as it is ultimately owed to policyholders in the form of claims payouts. However, the unique nature of Berkshire Hathaway's business model and its unparalleled ability to invest and generate returns from its float make it an extraordinary asset for the company.

Yes, you heard that correctly. Berkshire produces return on liabilities. And in the best case, the cost of these liabilities is zero, because insurers get paid upfront from their customers! There are even people claiming that Berkshire Hathaway could claim its float as asset. However, for us mere shareholders, it is much better that the company's book value might therefore be, say, a "defensive statement".

The sheer scale of Berkshire's insurance float and its astute management have allowed the company to generate significant returns, which in turn have been used to fuel further growth and investments in a diverse array of businesses. This virtuous cycle has been a key driver of Berkshire Hathaway's success over the years, and the acquisition of Alleghany Corporation is yet another strategic move that adds to the company's already formidable insurance float.

The Future of Berkshire Hathaway and Insurance Industry

With the addition of Alleghany Corporation to its insurance empire, Berkshire Hathaway has further cemented its position as a dominant player in the property-casualty insurance sector. The increased insurance float, combined with the company's unmatched financial strength and the expertise of Joe Brandon, presents a wealth of opportunities for future growth and expansion.

However, as with any industry, the insurance landscape is constantly evolving, and Berkshire Hathaway must remain nimble and adaptive to capitalize on new opportunities and navigate potential challenges. As the company continues to expand its insurance operations, it may encounter regulatory hurdles, increased competition, and the need to adapt to technological advancements and changing customer preferences.

In light of these potential challenges, the acquisition of Alleghany Corporation and its integration under Joe Brandon's leadership could serve as a catalyst for innovation and strategic evolution within Berkshire Hathaway's insurance business. By leveraging the combined knowledge, expertise, and resources of both companies, Berkshire Hathaway is well-positionedto thrive in the dynamic insurance industry and continue to generate value for its shareholders.

Moreover, this acquisition could potentially reshape the broader insurance landscape. As Berkshire Hathaway continues to grow its insurance float and expand its market presence, other industry players may be prompted to reevaluate their strategies, seek out partnerships, or pursue acquisitions in an effort to remain competitive. This ripple effect could lead to further consolidation within the insurance sector, ultimately changing the way the industry operates.


In conclusion, the acquisition of Alleghany Corporation by Berkshire Hathaway is a historic event that has far-reaching implications for both companies and the insurance industry as a whole. By increasing its insurance float to a staggering $164 billion, Berkshire Hathaway has not only solidified its position as a titan of the insurance world but has also demonstrated the critical importance of insurance float in driving the company's overall business strategy.

As we have explored throughout this article, the extraordinary value of insurance float, while not explicitly recognized in financial statements, has been a key driver of Berkshire Hathaway's success over the years. The company's unmatched financial strength, combined with the expertise of Joe Brandon and the synergies created through the acquisition of Alleghany Corporation, present a wealth of opportunities for future growth and expansion.

As Berkshire Hathaway moves forward in this new era of its insurance operations, it must remain adaptive and agile in order to capitalize on new opportunities and navigate potential challenges within the ever-evolving insurance landscape. With the powerful combination of an increased insurance float, a strong leadership team, and a proven track record of success, Berkshire Hathaway is poised to continue shaping the future of the insurance industry for years to come.
