Warren Buffett’s annual letter -- 7 things that will have everyone talking

Warren Buffett released his annual letter to shareholders of Berkshire Hathaway (BRK-B) Saturday morning. Every year it is one of the most widely read documents in the business world for the smart, funny and sometimes controversial insights from the Oracle of Omaha. Here are the seven things everyone will be talking about from this year’s letter:

(1) Berkshire had a good 2015, despite what the stock did

In a flat 2015 market, Berkshire fell about 12%, its worst decline since 2008. Buffett focused on the company’s 6.4% gain in book value -- the financial metric that he’s always used as an indicator of his conglomerate’s progress. Even though this was below the 13% average book value gain since the recession, it outpaced the 1.4% gain in the S&P including dividends.

Buffett reiterated his previous assertion that Berkshire will repurchase stock if the value of Berkshire trades at or below 1.2x book. Currently it is trading at about 1.3x book, which perhaps limits downside of the shares.

Owned businesses

Berkshire now owns 10 ¼ companies outright (including the 27% Kraft Heinz stake) that would be listed on the Fortune 500 were they independent.

“That leaves just under 98% of America’s business giants that have yet to call us. Operators are standing by."

Berkshire’s large insurance operations -- which earned $4.9 billion in 2015 versus $5.2 billion in 2014 -- put some downward pressure on results. However, an increase in “float” to $88 billion in these businesses can allow the company to fund investments. Buffett reminded investors why insurance has been good for Berkshire over the five decades he’s run the company.

In 2015, all of Berkshire’s other businesses -- including a railroad, utilities and energy, financial products, manufacturing and retail -- were more profitable than the previous year.

Buffett highlighted the turnaround in the company’s biggest non-insurance business, BNSF railroad, which improved its service to customers after $5.8 billion of capital spending.

Together with BNSF, the "Powerhouse Five" -- which includes Berkshire's five most profitable non-insurance businesses -- earned $13.1 billion in 2015. The acquisition of aerospace industry supplier Precision Castparts that closed in January will make the group the “Powerhouse Six.”

As for more M&A ahead? This year, Buffett didn't specifically hint at any elephant-sized deals on the horizon. Instead, he discussed successful "bolt-on acquisitions" and also reiterated that partnership opportuniites--including with 3G capital with whom he teamed up with in the 2013 purchase of Heinz--would continue.  Buffett said that he will only pursue a friendly takeover, even if hostile deals may sometimes be justified for other investors. At Berkshire, “we go only where we are welcome.”
