The business, and the score behind its five axes

The reading, in brief

Is it good

Return on invested capital was 8.9% in FY2025, in the band labelled "Around the cost of capital" (8.0% to 12.0%), on lines anchored on Damodaran's cost-of-capital data.

Today, against all covered US companies with this figure (1412 companies), 8.9% sits at the 59th percentile; the middle half of that group runs from 0.9% to 14.0%.

Is it safe

Interest coverage was 3.56x in FY2025, in the band labelled "Investment grade" (3.00x to 6.00x), on lines anchored on Damodaran's interest-coverage table.

The figures are computed from the accounts for fiscal 2025, the newest full year on file. 10 filed fiscal years on record, FY2016 to FY2025, from SEC EDGAR. Prices as of Oct 15, 2026. Ratios recomputed Oct 14, 2026. Two facts, because a recompute is not a fresh quote.

The year and the filing date name the statement each figure’s accounts are read from, and they stand even where the figure itself could not be computed: the line beneath a blank says what that statement did not carry. A figure’s name opens its formula and the filings behind it; a statement that names no SEC filing has no filing date, and reads n/a.

  • Current Ratio: A property trust presents an unclassified balance sheet: buildings are long-lived assets and mortgage debt is drawn against them, so there is no split between current and non-current for a current ratio to divide. Look at net debt to EBITDA and interest coverage instead.
  • Piotroski F-Score: 2 of the nine Piotroski signals are undefined for an equity REIT: signal 6 (rising current ratio), signal 8 (rising gross margin). We do not publish a partial score under the full score's name.
  • P/E Ratio: GAAP earnings for a property trust are charged with depreciation on buildings that are generally appreciating, so a P/E built on them overstates how expensive the trust is. Use price to FFO.
  • Altman Z-Score: Altman's Z-Score rewards working capital and asset turnover, neither of which a property trust has. It reads distress for healthy REITs by construction, so we do not show it.
  • Beneish M-Score: The Beneish M-Score is built on gross margin, receivables and asset quality indices estimated on non-financial firms. Those inputs are not defined here.
  • PEG Ratio: GAAP earnings for a property trust are charged with depreciation on buildings that are generally appreciating, so a P/E built on them overstates how expensive the trust is. Use price to FFO.
  • Gross Margin: No gross profit line is filed for this year.
  • Payout Ratio: A REIT pays out of funds from operations, not GAAP earnings. A payout ratio on earnings reads far above 100% for a perfectly safe distribution. Use the FFO payout ratio.
  • Price To Ncav: Net current asset value needs current assets, which an unclassified balance sheet does not report.
  • Dividend Coverage Ratio: Distribution coverage for a REIT is measured against funds from operations, not against free cash flow computed after acquisition capital expenditure.
  • Price Tangible Book: We do not hold this figure for this company, so there is nothing to show.

Running this once is arithmetic on public documents and you are welcome to it. Writing down why you own each company, in your own words and with the numbers that have to stay true for it to hold, and then having those numbers re-checked every night against the newest filed accounts, and against the latest close where a rule watches a price, is Professional, the plan a new account starts on for 30 days, one trial per person. It writes to you the day one breaks, and stays quiet when nothing does. The check runs every night at 23:30 UTC. A filing is picked up the night after it is published.

No card. 30 free days, and nothing is charged unless you choose a plan.

ValueScreener · valuescreener.ai · Computed from accounts filed with the SEC by this company, read from EDGAR, and from dated closing prices.
