Will it survive?

• Can it pay its interest? —
  Not enough data
  Little or no interest expense reported
  What this means

  Operating income wasn't found in the filing data.

• How heavy is the debt, net of cash? $706M
  Net debt
  Cash $403M − debt $1.1B
  What this means

  Netting $403M of cash and short-term investments against $1.1B of debt leaves $706M owed. 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? 49d
  Tight
  DSO 9 + DIO 91 − DPO 51 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 —
  Not enough data
  Industry peers: median 4%
  What this means

  The filing data didn't include the inputs for this check.

• Owner-earnings margin 21%
  High through the cycle
  10-yr median margin, range -9%–29%; latest $322M = operating cash $505M − maintenance capex $183M
  Industry peers: median 12%
  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 24% of revenue this year, a 21% median across 10 years.

• Are earnings backed by cash? 1.77×
  Cash-backed
  Cash from ops $505M ÷ net income $285M
  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? 2%
  Reinvests most of it
  Dividends + buybacks $6M ÷ Owner Earnings $322M
  What this means

  Of $322M Owner Earnings, $6M (2%) went back to shareholders, $6M dividends, $0 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? 0.52×
  Harvesting
  Capex $183M ÷ depreciation $349M
  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 · 0 of 5 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 Near
  Revenue ≥ $2B · $1.3B
  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 Miss
  Current ratio ≥ 2× · 1.13×
  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 · $1.1B vs $57M 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 Miss
  A profit every year (10-yr record) · 5 loss years
  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 · 8 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 —
  Earnings +33% over the record · —
  What this means

  Earnings were negative early in the record, a growth rate isn't meaningful.

• 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 $2.20/share (latest year $1.73), the averaged base the calculator's gate runs on. 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 5 of 10
  What this means

  Lost money in 5 year(s), look at what happened there before trusting the average.

• Owner earnings growth +37%/yr
  What this means

  Owner earnings grew about 37% a year over the record.

• Share count +0.0%/yr
  What this means

  Roughly flat share count, little dilution, little buyback.

• Dividend record paid
  What this means

  Paid a dividend in 8 of the years on record.
