Will it survive?

• Can it pay its interest? 4.1×
  Adequate
  Operating income $786M ÷ interest expense $193M
  What this means

  Comfortable in a normal year, but below the margin of safety Graham looked for. Worth checking how stable the coverage has been across a full cycle.

• How heavy is the debt, net of cash? $4.3B · 5.5× operating profit
  Heavy net debt
  Cash $182M − debt $4.5B
  What this means

  Netting $182M of cash and short-term investments against $4.5B of debt leaves $4.3B owed, about 5.5× a year's operating profit (5.7× on the gross debt, before the cash). Net debt is the leverage figure that matters: the cash is already set against the debt. Strategic or illiquid investments aren't counted here.

• How long is cash tied up? 39d
  Tight
  DSO 25 + DIO 38 − DPO 25 days
  What this means

  Days cash is tied up between paying suppliers and collecting from customers. Lower is better; a long cycle means growth itself eats cash.

Is it a good business?

• Return on invested capital 16%
  High through the cycle
  9-yr median, range 7%–37%; 8% latest = NOPAT $668M ÷ invested capital $8.7B
  Industry peers: median 30%
  What this means

  The rate the business earns on the money tied up in it, Buffett's north star, because over time a stock tracks the ROIC beneath it. Above ~15% sustained hints at a moat; a return below the cost of capital (~8%) erodes value as a business grows rather than building it — the test Buffett weighs most. The headline is the median of the last 9 years (it ran 8% most recently), so one peak or trough year doesn't set the verdict. Asset-light businesses (R&D expensed, little capital) read artificially high, pair this with Owner Earnings.

• Owner-earnings margin 5%
  Solid through the cycle
  10-yr median margin, range 2%–14%; latest $853M = operating cash $1.2B − maintenance capex $363M
  Industry peers: median 9%
  What this means

  What an owner could take out without starving the business: operating cash less the maintenance capital it must spend to hold its position — Buffett's owner earnings. That's 6% of revenue this year, a 5% median across 10 years. Treating stock comp as the real expense it is (less $54M of SBC) leaves $800M.

• Are earnings backed by cash? 2.79×
  Cash-backed
  Cash from ops $1.2B ÷ net income $435M
  What this means

  How much of reported profit showed up as operating cash. Above 1× is reassuring; well below suggests earnings lean on accruals. One year is noisy, growth and working-capital swings distort it, and this is operating cash, not free cash. Watch the multi-year trend.

How is the cash used?

• Where do the earnings go? 49%
  Returns about half
  Dividends + buybacks $414M ÷ Owner Earnings $853M
  What this means

  Of $853M Owner Earnings, $414M (49%) went back to shareholders, $0 dividends, $414M buybacks. Net of $54M stock comp, the real buyback was about $360M. Returning most of it is the mark of a mature business with little left to reinvest at a high return; reinvesting most could mean a long runway, or empire-building. The split doesn't say which; the return earned on it (see ROIC) does.

• Investing or harvesting? 0.61×
  Harvesting
  Capex $363M ÷ depreciation $591M
  What this means

  Descriptive, not a grade. Above ~1× means investing faster than assets wear out (growth, or, sustained for years, today's earnings carrying less depreciation than tomorrow's will). Below means spending less than it's wearing out (efficiency, or a melting asset base). The ratio won't tell you which; the filings will.

Graham’s defensive tests · 3 of 6 met

Graham’s numerical criteria for the defensive investor (The Intelligent Investor, ch. 14), run on the filings. A floor of safety, not a buy signal; many fine modern businesses fail his strictest liquidity rules by design.

• Adequate size Pass
  Revenue ≥ $2B · $15.2B
  What this means

  Big enough to weather a storm. Graham's 1972 floor was ~$100M of sales (≈ $700M today); we use a $2B revenue line as a conservative modern stand-in.

• Strong liquidity Near
  Current ratio ≥ 2× · 1.86×
  What this means

  Current assets at least twice current liabilities, near-term bills covered without touching the business. Strict by design: many cash-rich modern firms run leaner and miss it, holding their cushion in longer-dated securities.

• Conservative debt Miss
  Debt ≤ working capital · $4.5B vs $1.4B WC
  What this means

  Graham's rule that borrowings not exceed net current assets. Capital-heavy and buyback-heavy firms routinely fail it, read it next to interest coverage, not alone.

• Earnings stability Pass
  A profit every year (10-yr record) · no losses
  What this means

  Graham wanted earnings in each of the past ten years, the stability a defensive owner leans on.

• Dividend record Miss
  Uninterrupted dividends · none paid
  What this means

  An unbroken dividend was Graham's mark of durability. He wanted twenty years; the filings show about ten, and a single suspension breaks the streak. Non-payers, many fine modern compounders, fall outside his defensive net by design.

• Earnings growth Pass
  Earnings +33% over the record · +686%
  What this means

  At least a third more earnings than a decade ago, averaging three years at each end. Net income (not per-share), so stock splits don't distort it, buybacks and dilution show up in the share-count line instead.

• Moderate price —
  P/E ≤ 15 and P/E × P/B ≤ 22.5 · decided by the price
  What this means

  Graham's valuation gate, the wall he kept between a sound business and a sound investment. Three-year average earnings are $9.46/share (latest year $4.05), the averaged base the calculator's gate runs on, and book value is $40.46/share. Enter a price in “What the price implies” just below for the P/E, P/B, and whether it clears. But this is the rule Buffett outgrew: there's no hard P/E law, and a wonderful business can deserve a far richer multiple if the thesis holds, treat it as the bargain-hunter's floor, not a verdict on the price.

Durability & moat, 2016–2025

Whether the record’s returns held, and what the capital reinvested earned.

• Profitable years 10 of 10
  What this means

  Never lost money over the record, the earnings stability Graham insisted on.

• Return on capital ≥ 15% 5 of 9 yrs
  What this means

  A moat shows up as a high return on invested capital that holds year after year, not one good vintage.

• Operating margin 4% → 9% (3-yr avg ends)

  In the filing’s words The filing ties gains to its own pricing, but names price competition too — pricing power that is real yet contested, not unopposed. The margin shows who is winning.

  What this means

  Through the cycle the operating margin widened — about 4% early to 9% lately, median 5% — pricing power intact or improving.

• Reinvestment, incremental ROIC 16%
  What this means

  Every extra dollar the business reinvested came back at a high incremental return — the lens GBM read for a moat that reinvests rather than merely harvests. The record and the 10-K are where you check whether the rate holds.

• Owner earnings growth +29%/yr
  What this means

  Owner earnings grew about 29% a year over the record.

• Worst year 2016 · 3.7% op. margin
  What this means

  Stayed profitable even in its hardest year, the resilience that survives recessions.

• Share count −0.2%/yr
  What this means

  Roughly flat share count, little dilution, little buyback.
