Earnings quality
From 10-Q / 10-K XBRL filings. Sloan (1996) accruals: high accruals relative to assets have historically preceded earnings disappointments. Descriptive research, not a prediction.
Average — cash and accruals share the load
Earnings quality is middling — accruals at 6.2% of assets, close to the large-cap median. Neither a red flag nor a clean bill.
CY2024Q3Accruals / assets (TTM)CY2026Q2
Depreciation is disclosed annually by most filers, so quarterly values blend actuals with estimates — flagged on every reading. Method: TTM Sloan accruals ÷ average assets, scored 1–5 by quintile.
