Context

• These entries reflect an award (RSUs) that vested and converted into shares, followed by a report of disposal of the same number of shares on the same date. The $0.00 price reflects conversion/award activity rather than an open-market purchase price. Awards and immediate dispositions are often administrative (e.g., related to compensation or tax handling); they are not the same signal as a direct cash purchase or routine open-market sale by an insider.
