Some of Berkshire's insurance payments, Buffett explains, support permanently injured people for fifty years or more. Those people need the money to arrive. A higher investment return in the years before a missed payment would offer little consolation.
That obligation changes what counts as a good financial decision. Buffett is willing to earn less when pursuing more would put entrusted money at risk. A small chance of ruin can outweigh a probable gain. Financial strength also gives a company room to support workers and customers through difficulties, although it cannot make every promise affordable.
Insurance makes the distinction especially clear. Premiums arrive before claims are paid, leaving money the insurer can invest. Buffett calls this float. If underwriting breaks even, the funding has no underwriting cost. But it remains a liability to claimants, not spare money that owners can safely take away.
A business can own assets worth more than its debts and still run out of cash when a payment falls due. It may normally replace a maturing loan with another loan. During a credit shutdown, the old lender still expects payment while the new one disappears. A bank credit line is less reassuring when the bank itself is struggling.
Berkshire therefore held substantial reserves in short-term Treasury bills, accepting low yields rather than chasing a small improvement in instruments that might fail it during a panic. The reserve also left Berkshire able to buy when others needed to sell. That opportunity was a benefit of keeping money available, alongside the more basic duty to pay people already depending on it.
Buffett does allow borrowing. Long-lived utility and railroad assets can support long-term, fixed-rate debt from their own earnings, without a guarantee from the parent company. The payment source and terms matter. Paying interest with additional debt can keep a borrower apparently current while the unpaid bill compounds. The business must eventually cover all its interest after the spending needed to stay competitive. Recorded income cannot pay a claimant if the borrower will never produce the cash.
Promises hidden in contracts
Some demands for cash arrive without an ordinary loan maturing. A derivative ties a payment to something such as a share price or interest rate. If another party owes you an unsecured payment years ahead, your gain also depends on that party surviving and paying. A model's current estimate of profit cannot settle that question.
Getting out can be difficult too. After buying General Re, Berkshire tried to sell its sprawling derivatives operation and then wound it down. Getting largely out took about five years and more than four hundred million dollars in losses, even though Berkshire faced no financial pressure and markets were relatively calm.
In a crisis, a downgrade can require a company to post cash collateral. Losing that cash weakens its ability to pay, inviting another downgrade and another demand. Several counterparties may fail together because they depend on one another. Berkshire separately wrote a small number of contracts Buffett supervised personally, with no counterparty credit exposure. Berkshire could still lose money on its own commitments.
Households face a simpler version of the payment problem. A mortgage must fit the verified income a household actually earns, with a down payment from genuine savings. An expected promotion, higher house price, or future refinancing is an uncertain rescue. Owing more than the house is worth is different from being unable to make its payments. Buffett also points to lenders who collected fees and sold loans onward. They could receive their reward long before somebody else discovered the loss.
What financial strength makes possible
Customers need businesses to keep investing. A railroad cannot distribute all its apparent profit while neglecting the track. Utilities and railroads must provide dependable service and fund assets whose useful lives extend far into the future. Buffett describes a reciprocal bargain. Businesses supply adequate capital and efficient service, while society and regulators allow reasonable returns. Starving either the system or its investors eventually undermines that bargain.
He and Charlie Munger also regard taxes as part of their contribution to society. The market rewards their skills more generously than some work of equal or greater social usefulness. They accept taxation as a partial correction, alongside sensible tax arrangements within the rules. A strong private return does not settle what a business owes others.
Workers bring that obligation closer to home. Berkshire's textile employees cooperated despite low pay, and managers worked hard and reported problems honestly. Buffett was willing to accept below-average profits to keep the mills running while he believed they could generate modest cash.
That belief proved wrong. New machinery could lower costs, but competitors could buy similar equipment and drive prices down again. The business consumed substantial cash, and Buffett eventually expected the drain to continue indefinitely. Berkshire closed the mills in nineteen eighty-five after unsuccessful attempts to make them viable. Buffett acknowledged that he had stayed too long.
Lower profits could be an acceptable price for loyalty. An operation expected to consume cash forever would keep drawing on resources needed elsewhere. Keeping a promise requires enough financial strength to honor it, and the honesty to recognize when one commitment is endangering the others.
Three things to keep
Cash must be available when promises come due, even if lenders disappear.
Borrowing and contracts need limits that survive bad conditions.
Supporting people can justify lower returns, but not an endless cash drain.
