Having loads of liquidity, though, lets us sleep well.

Excerpt:

Borrowers then learn that credit is like oxygen. When either is abundant, its presence goes unnoticed. When either is missing, that’s all that is noticed. Even a short absence of credit can bring a company to its knees.
In September 2008, in fact, its overnight disappearance in many sectors of the economy came dangerously close to bringing our entire country to its knees.

Charlie and I have no interest in any activity that could pose the slightest threat to Berkshire’s wellbeing. (With our having a combined age of 167, starting over is not on our bucket list.) We are forever conscious of the fact that you, our partners, have entrusted us with what in many cases is a major portion of your savings. In addition, important philanthropy is dependent on our prudence. Finally, many disabled victims of accidents caused by our insureds are counting on us to deliver sums payable decades from now. It would be irresponsible for us to risk what all these constituencies need just to pursue a few points of extra return.

A little personal history may partially explain our extreme aversion to financial adventurism. I didn’t meet Charlie until he was 35, though he grew up within 100 yards of where I have lived for 52 years and also attended the same inner-city public high school in Omaha from which my father, wife, children and two grandchildren graduated. Charlie and I did, however, both work as young boys at my grandfather’s grocery store, though our periods of employment were separated by about five years. My grandfather’s name was Ernest, and perhaps no man was more aptly named. No one worked for Ernest, even as a stock boy, without being shaped by the experience.

On the facing page you can read a letter sent in 1939 by Ernest to his youngest son, my Uncle Fred. Similar letters went to his other four children. I still have the letter sent to my Aunt Alice, which I found – along with $1,000 of cash – when, as executor of her estate, I opened her safe deposit box in 1970.

Ernest never went to business school – he never in fact finished high school – but he understood the importance of liquidity as a condition for assured survival. At Berkshire, we have taken his $1,000 solution a bit further and have pledged that we will hold at least $10 billion of cash, excluding that held at our regulated utility and railroad businesses. Because of that commitment, we customarily keep at least $20 billion on hand so that we can both withstand unprecedented insurance losses (our largest to date having been about $3 billion from Katrina, the insurance industry’s most expensive catastrophe) and quickly seize acquisition or investment opportunities, even during times of financial turmoil.
