Cash is King

# Cash is King **Cash is King** encapsulates Buffett's belief that the ultimate measure of a business's success is its ability to generate cash, not its reported accounting earnings. Cash is the oxygen that sustains a business; without it, no enterprise can survive. ## Why Cash Matters More Than Earnings Accounting earnings can be manipulated through choices about depreciation, capitalization, and assumptions. Cash, by contrast, is harder to manipulate—it either exists or it doesn't. A business that generates strong cash flow can: - Reinvest in its own growth - Repurchase shares at attractive prices - Pay dividends - Acquire other businesses - Survive economic downturns A business with impressive earnings but weak cash flow may be on the verge of collapse. > "Cash flow is the financial oxygen that keeps a business alive. When the cash runs out, the business dies, regardless of what the income statement shows." ## Free Cash Flow The key metric is **free cash flow**: the cash generated by a business after all necessary capital expenditures have been made. Free Cash Flow = Operating Cash Flow − Maintenance Capex If a business requires $100 million in capex just to maintain its current position, and it generates $150 million in operating cash flow, its free cash flow is $50 million—not $150 million. ## The Cash Conversion Test Buffett applies what he calls the "cash conversion test": 1. Does the business generate significant free cash flow? 2. Does it generate free cash flow relative to its market value? 3. Does management deploy free cash flow wisely? Businesses that fail the cash conversion test—businesses that generate accounting earnings but consume cash—should be viewed with extreme skepticism. ## Cash Piles: When to Be Cautious Holding excessive cash is not always wise either. Businesses (and investors) that hold too much cash are implicitly making a decision that there are no attractive uses for capital. This can indicate either extraordinary discipline or a failure to invest. Berkshire has famously maintained large cash positions at times, but Buffett has always deployed it aggressively when opportunities arose—during market crashes and crises, when the "elephants" he has long sought become available at distressed prices.
