It’s a Berkshire weekend. In fact, it’s a “Woodstock for Capitalists” weekend.

On Saturday, Warren Buffett’s legions of disciples converged on Nebraska to wander an elaborate flea market and consult the Oracle, who held court in an Omaha arena that was “already three-quarters full within half an hour of the doors opening,” as the AP noted.

Typically, Berkshire’s annual shareholder meetings are jovial affairs, but this one was a bit somber. For the first time, Charlie Munger didn’t attend.

As regular readers are apprised, I don’t dedicate a lot of editorial bandwidth to Berkshire’s annual gatherings. CNBC has an unassailable monopoly on Omaha coverage. And they’re welcome to it.

That said, I’d be remiss not to mention that Berkshire’s quarterly report showed Buffett’s cash pile rose by nearly $21.4 billion, the most in years. It was the seventh consecutive quarterly increase.

Buffett’s McDuck vault now holds a staggering $189 billion, all of which, you’ll note, is generating somewhere in the neighborhood of 5%. The line item dedicated specifically to T-bills rose 18.4% from December 31 through the end of March.

I don’t know what most 93-year-olds hoard. Vintage oil cans, maybe? You’d have to ask Mike Wolfe. But this 93-year-old hoards money. You can’t take it with you, but by God if you could, this camel couldn’t just bribe his way through the eye of the needle, he could bid for whole damn Kingdom.

Speaking of needles, Buffett suspects nothing can move Berkshire’s. Last quarter, he said the conglomerate’s now so big that Berkshire has “no possibility of eye-popping performance.” That’s one excuse Buffett offers for the inexorable rise in his cash balance. Relatedly, he suggests there are simply no attractive cash-deployment opportunities, big, small or anything in-between.

There is one thing Buffett likes, though: His own cooking (with lots of salt and Cherry Coke to wash it down). Berkshire spent another $2.6 billion on buybacks in Q1.

As the figure shows, last quarter’s buybacks were the largest in a year. (Mmm mmm good.)

Far be it from me to question the (in)decisions of capitalism’s Michael Jordan, but I gotta tell you: Common sense dictates that Buffett’s age is a factor in Berkshire’s increasingly frugal approach to cash management. Buffett’s just piling up money and buying shares of himself. It beggars belief that nobody at Berkshire has any better ideas. Rather, my guess is that Buffett’s becoming harder to convince as tends to happen when we age.

As for the rest of Berkshire’s report, operating earnings improved markedly thanks in part to better underwriting results. I don’t know what the future holds for the insurance business in a world that’s very likely to burn and flood humanity into ever-dwindling temperate zones. But that’s a problem for Buffett’s successors. Whoever they are.

“Succession is quite frankly a top-of-mind issue for most investors,” a senior VP at CFRA said. “It’s kinda like the elephant in the room given Buffett’s age [and] Munger’s passing.”
