Securities Analyst

TL;DR: Insider disposition was modest relative to remaining stake; transaction is a routine disclosure.

The sale of 7,421 shares at a weighted average of $56.7147 reduces the reporting person's direct position but leaves a sizeable retained interest of 53,343 shares when including RSUs.
