Will it survive?

• Can it pay its interest? 34.5×
  Comfortable
  Operating income $308M ÷ interest expense $9M
  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? $153M · 0.5× operating profit
  Modest net debt
  Cash $1M − debt $154M
  What this means

  Netting $1M of cash and short-term investments against $154M of debt leaves $153M owed, about 0.5× a year's operating profit. 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? —
  Not enough data
  What this means

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

Is it a good business?

• Return on invested capital —
  Not enough data
  Industry peers: median 9%
  What this means

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

• Owner-earnings margin 64%
  High through the cycle
  10-yr median margin, range 48%–101%; latest $203M = operating cash $310M − maintenance capex $107M
  Industry peers: median 25%
  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 48% of revenue this year, a 64% median across 10 years. Treating stock comp as the real expense it is (less $10M of SBC) leaves $193M.

• Are earnings backed by cash? 1.15×
  Cash-backed
  Cash from ops $310M ÷ net income $270M
  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? —
  Not enough data
  What this means

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

• Investing or harvesting? 2.90×
  Expanding
  Capex $107M ÷ depreciation $37M
  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 Miss
  Revenue ≥ $2B · $422M
  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× · 3.88×
  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 · $154M vs $71M 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 · +104%
  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 $1.51/share (latest year $1.27), 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 10 of 10
  What this means

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

• Operating margin 35% → 73% (3-yr avg ends)

  In the filing’s words The margin widened even though the filing names price competition — the gain came from volume or cost, not pricing power. Read where.

  What this means

  Through the cycle the operating margin widened — about 35% early to 73% lately, median 48% — pricing power intact or improving.

• Owner earnings growth +0%/yr
  What this means

  Owner earnings grew about 0% a year over the record.

• Worst year 2016 · 9.2% op. margin
  What this means

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

• Share count +0.3%/yr
  What this means

  Roughly flat share count, little dilution, little buyback.
