Will it survive?

• Can it pay its interest? 8.7×
  Comfortable
  Operating income $466M ÷ interest expense $53M
  What this means

  Operating profit covers interest with the kind of margin Graham wanted for a defensive holding. Necessary, not sufficient, it says solvent, not cheap.

• How heavy is the debt, net of cash? $556M · 1.2× operating profit
  Modest net debt
  Cash $839M + ST investments $260M − debt $1.7B
  What this means

  Netting $1.1B of cash and short-term investments against $1.7B of debt leaves $556M owed, about 1.2× a year's operating profit (3.6× 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? 176d
  Long (60+ days)
  DSO 70 + DIO 139 − DPO 34 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 6%
  Below average through the cycle
  10-yr median, range -1%–12%; the latest year is left out — large non-operating charges put its operating line well above pretax profit
  Industry peers: median 9%
  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 10 years, 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 17%
  High through the cycle
  10-yr median margin, range 14%–27%; latest $453M = operating cash $654M − maintenance capex $201M
  Industry peers: median 21%
  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 22% of revenue this year, a 17% median across 10 years.

• Are earnings backed by cash? $654M
  Loss, but cash-generative
  Net income ($41M) · cash from operations $654M
  What this means

  The company reported a net loss, so a conversion ratio isn't meaningful. What matters then is whether operations still threw off cash, here, they did.

How is the cash used?

• Where do the earnings go? 74%
  Returns about half
  Dividends + buybacks $334M ÷ Owner Earnings $453M
  What this means

  Of $453M Owner Earnings, $334M (74%) went back to shareholders, $54M dividends, $280M buybacks. 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? 1.04×
  Maintaining
  Capex $201M ÷ depreciation $194M
  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 · $2.1B
  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 Pass
  Current ratio ≥ 2× · 3.90×
  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 Near
  Debt ≤ working capital · $1.7B vs $1.5B 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 Near
  A profit every year (10-yr record) · 1 loss year
  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 · 1 of 10 yrs
  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 · +173%
  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 $1.31/share (latest year $-0.19), the averaged base the calculator's gate runs on, and book value is $17.42/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 9 of 10
  What this means

  Lost money in 1 year(s), look at what happened there before trusting the average.

• Return on capital ≥ 15% 0 of 10 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 12% → 16% (3-yr avg ends)
  What this means

  Through the cycle the operating margin widened — about 12% early to 16% lately, median 18% — pricing power intact or improving.

• Reinvestment, incremental ROIC returns capital
  What this means

  The capital base barely grew: this business returns cash through dividends and buybacks rather than reinvesting. Judge it on the cash returned, not on compounding.

• Owner earnings growth +8%/yr
  What this means

  Owner earnings grew about 8% a year over the record.

• Worst year 2019 · −1.7% op. margin
  What this means

  Operations went underwater in 2019, understand why before trusting the good years.

• Share count −1.0%/yr
  What this means

  The share count is shrinking, buybacks are quietly growing your slice of the business.

• Dividend record paid
  What this means

  Paid a dividend in 1 of the years on record.
