Over the weekend, Warren Buffett and his team hosted some 40,000 people in Omaha for Berkshire Hathaway's annual shareholder meeting. And during the event the 94-year-old announced that he would be retiring at the end of the year. This is after 55 years as CEO, which makes him the longest-serving chief executive of an S&P 500 company.
What a run. Thanks for all the wisdom that you have shared over the years, Warren. In honor of this milestone, I decided to go back and reread his last shareholder letter (which was published back in February). His comments on the insurance industry are particularly interesting, and naturally relevant to real estate.
Over the decades, Warren has talked a lot about the benefits of owning insurance companies, namely the "money-up-front, loss-payments-later" model. It creates a "float" of cash that can be invested in the interim. But the flip side of this benefit is that it can sometimes conceal a shitty business.
As a business, if you have to pay your costs up front before you sell your products or services, then it's pretty easy to determine if you're not making any money. But in insurance, there's a long-tail of liabilities that can be far more insidious and that may not appear for many years, or even decades according to Warren.
There's also climate change bringing more uncertainty:
In general, property-casualty (“P/C”) insurance pricing strengthened during 2024, reflecting a major increase in damage from convective storms. Climate change may have been announcing its arrival. However, no “monster” event occurred during 2024. Someday, any day, a truly staggering insurance loss will occur – and there is no guarantee that there will be only one per annum.
Think back only 135 years when the world had no autos, trucks or airplanes. Now there are 300 million vehicles in the U.S. alone, a massive fleet causing huge damage daily. Property damage arising from hurricanes, tornadoes and wildfires is massive, growing and increasingly unpredictable in their patterns and eventual costs.
In a perverse way, all of this is good for the insurance business. More economic risk means higher premiums and a greater overall need for insurance products. But you have to accurately underwrite this risk:
Properly pricing P/C insurance is part art, part science and is definitely not a business for optimists. Mike Goldberg, the Berkshire executive who recruited Ajit, said it best: “We want our underwriters to daily come to work nervous, but not paralyzed.”
This reminds me. I was speaking with one of our insurance advisors a few years ago and he made a comment that he was going to be "on risk for the project." I responded by half-jokingly saying "it's funny, you see only risk, and I see an opportunity to create something special for the city." Both of us then laughed, but there's obviously some truth to these two perspectives.
I guess I chose the right profession.

Among other things, insurance companies now use aerial photography, combined with AI, to better assess property-level risk. Here's an excerpt from Bloomberg Green:
“Weather and catastrophe losses are running ahead of the ability to manage them, and many insurers are having trouble sustaining their business because they’re not getting the right rates,” said Jay Guin, chief research officer of the extreme event solutions team at Verisk, a catastrophe modeling firm. “AI changes the equation.”
Zurich Insurance Group AG, one of the largest insurers in Europe, uses AI powered risk-modeling software to assess catastrophe risk and often tweaks it for its own purpose.
“If there’s fire hazard like vegetation, overhang or debris in your backyard that shouldn’t be there, we can tell you to lower the risk otherwise we may not be able to underwrite you,” said Ericson Chan, chief information and digital officer of the Swiss company.
What AI allows is a level of granularity that just wasn't possible when humans were the ones who had to do it. Insurers now talk about "continuous remote risk monitoring," meaning they can use AI-powered aerial imagery to constantly check on that risky debris in your backyard.
This feels like quite an improvement for the insurance industry. But when you more accurately price risk, I would imagine that it will lead to more insurers deciding to stay clear of certain risks and certain properties, as has already been the case in places like California.
Here's an excerpt from a recent post by Scott Galloway talking about LA's devastating wildfires:
The question isn’t whether to rebuild, but where. Pacific Palisades is a wonderful place to live, but those amazing views of beautiful topography of foothills, mountains, canyons, and ridgelines are located in fire zones. Early estimates put the total cost of the wildfires at $250 to $275 billion. The property insurance bill is expected to easily top $20 billion. California’s insurance market was already in crisis, as leading insurers had done the math and decided to leave the state or not renew policies in fire-prone areas. California’s state-backed FAIR Plan is the insurer of last resort in these areas. Statewide, the number of FAIR Plan policies in 2024 increased 40% from 2023, and 85% in Pacific Palisades. Continuing to underwrite wood-built craftsman homes in Altadena (median home value: $1.3 million) and mansions along PCH is a wealth transfer from California’s taxpayers to some of its wealthiest people.
This isn’t unique to California; 10 states across the political spectrum, including Florida and Texas, sued a federal flood insurance program after it adjusted premiums to better reflect climate realities. As one meme put it: You may not believe in climate change, but your insurance company does.
He's not wrong, though I'm sure that the impacts of the deadliest and most destructive wildfires in California's history were felt by a broad cross section of people. And, no matter how much money you have, losing your home is going to be traumatizing. My mom's house in New Brunswick burnt down when she was a young girl and she remembers it vividly. You lose things that are priceless. Still, the questions of where and how to rebuild are important ones. Living in a high-risk area has costs associated with it. I do think it's only fair to ask who will be underwriting these costs.
