Will it survive?

• Can it pay its interest? -6.4×
  Does not cover its interest
  Operating income ($133M) ÷ interest expense $21M
  What this means

  A full year of operating profit didn't cover the interest bill. This is the zombie zone: the business depends on refinancing, asset sales, or forbearance to service its debt.

• How heavy is the debt, net of cash? $6M
  Net debt against an operating loss
  Cash $123M + ST investments $11M − debt $140M
  What this means

  Netting $134M of cash and short-term investments against $140M of debt leaves $6M owed, with no operating profit this year to measure it against — understand that combination before anything else about the company. 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? 155d
  Long (60+ days)
  DSO 85 + DIO 134 − DPO 63 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 4%
  Below average through the cycle
  5-yr median, range -39%–121%; -17% latest = NOPAT ($105M) ÷ invested capital $613M
  Industry peers: median 2%
  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 5 years (it ran -17% 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 3%
  Thin through the cycle
  10-yr median margin, range -4%–14%; latest ($10M) = operating cash $51M − maintenance capex $62M
  Industry peers: median 2%
  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 -1% of revenue this year, a 3% median across 10 years.

• Are earnings backed by cash? $51M
  Loss, but cash-generative
  Net income ($171M) · cash from operations $51M
  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? —
  No surplus to allocate
  What this means

  The business didn't generate positive Owner Earnings this year, so any distributions came from the balance sheet or borrowing, not from operations.

• Investing or harvesting? 0.73×
  Harvesting
  Capex $62M ÷ depreciation $85M
  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 · 1 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 Near
  Current ratio ≥ 2× · 1.66×
  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 Pass
  Debt ≤ working capital · $140M vs $292M 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) · 6 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 · 7 of 8 tagged 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. 2 years of this record are untagged in the data, with the dividend paid on both sides; a lone missing tag is treated as unknown, not a suspension, so the streak is judged on the tagged years.

• 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 $-0.12/share (latest year $-0.91), the averaged base the calculator's gate runs on, and book value is $3.19/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 4 of 10
  What this means

  Lost money in 6 year(s), look at what happened there before trusting the average.

• Return on capital ≥ 15% 2 of 6 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 −6% → 1% (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 −6% early to 1% lately, median 2% — pricing power intact or improving.

• Reinvestment, incremental ROIC 27%
  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 +2%/yr
  What this means

  Owner earnings grew about 2% a year over the record.

• Worst year 2016 · −23.7% op. margin
  What this means

  Operations went underwater in 2016, understand why before trusting the good years.

• Share count +1.0%/yr
  What this means

  The share count is rising, dilution works against you on a per-share basis.

• Dividend record paid
  What this means

  Paid a dividend in 7 of the years on record.
