 Summary and Key Insights from Berkshire Hathaway’s 1978 Shareholder Letter

 Through the lens of Moat In You

1. Merger Complications and Accounting Complexity

In 1978, Berkshire Hathaway merged with Diversified Retailing. As a result, Blue Chip Stamps — now majority-owned by Berkshire — had to be fully consolidated into the company’s financial statements. Instead of showing just Berkshire’s share of profits, the full earnings and expenses of Blue Chip and its subsidiaries were now included.

While this accounting method is technically correct, Warren Buffett acknowledged that it can actually make things more confusing for shareholders. Combining results from different industries like textiles, candy, insurance, and newspapers makes it harder to understand how each business is truly performing.

Another complexity arose from having to restate past financial statements as if the merger happened earlier, which complicated comparisons across years.

2. Strong Performance in 1978, But With Realistic Expectations

Berkshire reported a solid return on beginning equity — 19.4% — one of the best in its history at that time. Much of the growth in shareholder equity over recent years had come from capital gains.

But Buffett was clear-eyed about the future. He warned that such high returns weren’t sustainable, especially with the insurance cycle cooling off. Still, even if the percentage returns dropped, he expected total dollar profits to rise, thanks to a larger capital base. He remained optimistic about long-term gains from smart equity investments.

3. How Berkshire’s Businesses Performed

By the end of 1978, Berkshire and its subsidiaries employed about 7,000 people and generated more than $500 million in revenue. Let’s look at how the individual businesses did:

• Insurance brought in significant investment income and modest underwriting profits.

• Retail (Associated Retail Stores) was consistently profitable and efficient with capital.

• See’s Candies remained a steady performer.

• Textile operations barely broke even, suffering from industry-wide issues like low differentiation and overcapacity.

• Illinois National Bank did very well, outperforming peers with low asset risk — though regulatory requirements meant Berkshire would have to sell it.

• Other businesses like Wesco Financial performed well, while the Buffalo Evening News was a money-loser.

4. The Hard Truth About Tough Industries and Investment Discipline

Buffett used the textile business as a real-life example of how difficult some industries can be — even when you run them well. Capital-intensive industries with little pricing power and slow inventory turnover tend to deliver poor returns.

On the insurance side, 1978 was a rare year where underwriting profits and investment income both did well. But Buffett was cautious, warning that industry conditions were bound to turn, with costs rising faster than premiums.

When it came to investing the insurance float, Buffett stuck to his principles: focus on businesses you understand, that have strong long-term prospects, are run by capable and honest managers, and are available at an attractive price.

One standout investment was SAFECO — a well-managed insurance company that Berkshire bought below book value. Another was The Washington Post, which had significant unrealized gains.

5. Putting Buffett’s Investment Philosophy to Work

Buffett explained that sometimes it’s better to buy shares of great companies on the stock market than to acquire entire businesses. That’s because the stock market often undervalues excellent companies, while whole-company acquisitions can be expensive — especially if the target is mediocre.

He also made it clear he’s fine with owning small stakes in wonderful companies, even if Berkshire has no control. What matters most is the business and management quality, not control.

Buffett also emphasized the importance of retained earnings — profits that companies keep instead of distributing. As long as those retained earnings are reinvested wisely, they can drive significant value, even if they don’t show up directly in reported earnings.

He acknowledged that growing a business from scratch is much harder than buying a good one that’s already running well — an honest look at some of Berkshire’s mixed results in expanding its insurance operations.

6. Management and Corporate Culture

One thing Buffett made very clear: the people running Berkshire’s businesses — from retail stores to banks — were exceptional. He especially appreciated managers who operated with an “owner’s mindset,” caring about the business like it was their own. Age didn’t matter — performance and stewardship did.

Key Takeaways for Investors from Moat In You

• Don't blindly follow the numbers. Buffett reminds us that GAAP accounting often hides the real story. Always dig deeper to understand a company’s economic reality.

• Avoid trendy industries with weak economics. Capital-intensive, competitive industries rarely produce great returns, no matter how skilled the managers are.

• Stick to your circle of competence. Only invest in businesses you fully understand.

• Be selective and patient. Buffett doesn't invest unless the price is right. That discipline is key to avoiding mistakes.

• Focus on the business, not the stock. Ignore short-term market noise — invest for the long-term based on business fundamentals.

• Quality over quantity. A concentrated portfolio of excellent companies will usually outperform a scattered collection of average ones.

• Retained earnings matter. Great companies quietly build shareholder wealth by reinvesting their profits smartly. Look beyond the headlines.
