Z″ 12.01 · distress below 1.10, grey to 2.60, safe above.
Z″ factor contributions
X1 Working capital / assets
Short-term liquidity. Carries more weight in Z″ than in classic Z.
0.556.56 × = 3.58X2 Retained earnings / assets
Cushion from years of profits. Share buybacks can push this negative at otherwise healthy firms.
0.773.26 × = 2.50X3 EBIT / assets
Operating return on assets. Highest weight in Z″.
0.336.72 × = 2.20X4 Book equity / liabilities
Book equity versus the liability stack. Sales / assets is omitted so asset-light names are not punished for turnover.
3.561.05 × = 3.73
Five-year path
Need two annual 10-Ks to draw a path. The desk will pull this issuer’s filings rather than invent a series.
Overview
rule-v1
FASTENAL CO is on Z″ at 12.01 (safe) for FY2025, from an SEC 10-K. Book equity / liabilities is the line that sets the print; working capital / assets is the runner-up. This is the first live year on the desk. No market tape loaded. Z″ drops sales/assets so asset-light names are not punished for turnover. X4 is book equity on every name.
Book screen Safe; market PD —. Tape not priced — not a single default call.
Market DD · naive Merton
No market tape yet.
Pull a year of closes (Yahoo, Nasdaq if Yahoo is limited) and size equity from Nasdaq cap or EDGAR shares. Distance-to-default and 1-year PD stay blank until then.
