Securities Compliance Analyst

Forms indicate routine, pre-arranged dispositions rather than event-driven market activity.

The entries are labeled as 10b5-1 Sales, which the excerpt identifies by date and share count; such labeling typically denotes pre-planned trading instructions. The filing names the executing broker and records gross proceeds per trade.

Regulatory implications are routine disclosure; further filings may show aggregate totals or confirm whether these trades exhausted a plan, but timing and plan terms are not provided in the excerpt.
