Berkshire Hathaway Letters to Shareholders: 1965-2024

by Warren Buffett

When I agreed in 1998 to merge Berkshire with Gen Re, I thought that company stuck to the three rules I’ve enumerated. I had studied the operation for decades and had observed underwriting discipline that was consistent and reserving that was conservative. At merger time, I detected no slippage in Gen Re’s standards. I was dead wrong. Gen Re’s culture and practices had substantially changed and unbeknownst to management — and to me — the company was grossly mispricing its current business. In addition, Gen Re had accumulated an aggregation of risks that would have been fatal had, say, terrorists detonated several large-scale nuclear bombs in an attack on the U.S. A disaster of that scope was highly improbable, of course, but it is up to insurers to limit their risks in a manner that leaves their finances rock-solid if the “impossible” happens. Indeed, had Gen Re remained independent, the World Trade Center attack alone would have threatened the company’s existence. When the WTC disaster occurred, it exposed weaknesses in Gen Re’s operations that I should have detected earlier. But I was lucky: Joe and Tad were on hand, freshly endowed with increased authority and eager to rapidly correct the errors of the past. They knew what to do — and they did it.
