Calculations over this company’s filings, each compared with a stated threshold. They indicate where to read more closely; they are analytical evidence, not conclusions, and none implies wrongdoing.

Insider filing timing

P-08 · Calculated

Elevated

FY 2026-07-30

Whether several insiders filed Form 4 in the 14 days before recent 8-K events.

1 8-K event(s) preceded by clustered Form 4 activity within 14 days

P-08 inputs
Input	Value
model score (0–100)	24.0
clusters.0.event_8k	2026-04-30
clusters.0.form4_count	3
clusters.0.form4_dates	["2026-04-17","2026-04-27"]
form4_total_1y	42
events_8k_1y	8
window_days	14
note	Timing pattern only — direction (buy/sell) requires parsing each Form 4 XML; treat as a read-the-filings triage flag, not an accusation.
