Warren Buffett's Guide to Spotting Bankruptcy: The 4 Balance Sheet Red Flags
For any investor, avoiding catastrophic losses is just as important as finding winners. In this talk, Warren Buffett distills seven decades of experience into four simple, powerful balance sheet red flags that predict financial distress with remarkable accuracy. Ignoring these signs once cost him $358 million on a US Air investment. Here’s how you can protect your capital.
The Core Philosophy: The Balance Sheet Never Lies
Most investors focus on the income statement—revenue and earnings growth. But that’s the rearview mirror. The balance sheet is your windshield; it shows whether a company has the financial strength to survive the road ahead. Revenue can be manipulated, but cash, debt, and working capital reveal the unvarnished truth.
The 4 Red Flags That Predict Bankruptcy
1. Excessive Debt Relative to Equity
What it is: A dangerously high debt-to-equity ratio. Debt creates mandatory payments; equity provides flexibility.
Why it’s fatal: In a downturn, debt payments become a noose. Creditors can force bankruptcy if payments are missed.
The Lesson from Lehman Brothers: In 2007, Lehman had a debt-to-equity ratio of 30-to-1. When its assets lost just 3.3% of their value, shareholder equity was wiped out. This massive leverage made its collapse inevitable.
Your Action: Calculate Total Debt / Total Equity. For most companies, a ratio above 2-3 is dangerous. Watch the trend—if it’s rising, risk is increasing.
2. Declining Cash & Ballooning Receivables
What it is: Cash is falling while accounts receivable (money owed by customers) is rising much faster than sales.
Why it’s fatal: It signals customers aren’t paying, or the company is offering desperate credit terms to book fake revenue. This creates an illusion of growth while the company runs out of real money.
The Lesson from a 1990s Tech Firm: It reported 20% growth, but cash halved while receivables soared 150%. The "revenue" was uncollectable, and the stock crashed.
Your Action: Calculate Days Sales Outstanding (DSO). A DSO rising above 90-120 days is a major red flag. Monitor the cash conversion cycle.
3. Declining Tangible Assets / Inflated Intangibles
What it is: A balance sheet loaded with goodwill and intangible assets but lacking tangible assets (cash, inventory, property) that hold real value in a crisis.
Why it’s fatal: Goodwill is worth $0 in bankruptcy. It’s an accounting entry for overpayment on past acquisitions. A company with negative tangible equity has no real asset cushion.
The Lesson from General Electric: GE accumulated $75B in goodwill. When stripped away, its tangible equity was negative. The eventual write-offs devastated the stock.
Your Action: Calculate Tangible Equity (Total Equity - Intangibles). If it’s low or negative, the company’s financial strength is an illusion.
4. Inadequate Working Capital
What it is: Current liabilities exceed current assets (a current ratio below 1.0), meaning the company can’t cover bills due within a year.
Why it’s fatal: It leaves no margin for error. Any disruption—a sales miss, a delayed payment—can cause immediate insolvency.
The Lesson from Toys "R" Us: Before its 2017 bankruptcy, its current ratio was 0.73. It was dependent on perfect holiday sales and collapsed when they disappointed.
Your Action: Calculate the Current Ratio and the more conservative Quick Ratio (excludes inventory). Understand why it’s low: Is it from efficiency (like Amazon) or from distress (high debt, no cash)?
The Ultimate Warning: Multiple Red Flags
A single flag can be a warning, but multiple flags are a death sentence. Sears Holdings is the classic example. Years before its 2018 bankruptcy, it exhibited all four: soaring debt, vanishing cash, negative tangible equity, and crippled working capital. The balance sheet told the entire story years in advance.
The Buffett Playbook: How to Act on This Knowledge
For Current Holdings: If a company you own shows these signs, sell immediately. Do not hope for a turnaround. "Take your loss and move on."
For New Investments: Screen the balance sheet first, before looking at the growth story. If red flags appear, walk away. There are thousands of stocks; avoid the financially distressed.
For Business Owners: Use these principles to build a "fortress balance sheet" for your own company. Prioritize survival over aggressive growth.
The Investor's Mindset
Seek Simplicity: These four rules are simple but have proven effective across decades and industries.
Prioritize Safety: The best managers are obsessed with balance sheet strength. They know survival comes first, growth second. Look for companies with minimal debt, ample cash, and strong working capital—they sleep well at night and emerge stronger from crises.
Trust Reality: "Cash is cash. Debt is debt. Working capital is working capital." These numbers reflect reality. Learning to read them will put you ahead of 90% of investors.
Final Takeaway: You don't need to predict the future. You just need to read the present accurately on the balance sheet. This discipline will help you avoid catastrophic losses and build lasting wealth by investing in companies built to last.
