"This transaction was made pursuant to a Rule 10b5-1 trading plan"

Class A Common Stock financial
"security_title: Class A Common Stock reported in the transaction"
Class A common stock is a category of a company’s shares that carries a specific set of ownership rights—most commonly defined voting power and claims on dividends—set out in the company’s charter. For investors it matters because the class determines how much influence you have over corporate decisions, the share’s likely dividend and trading behavior, and how it compares in value to other share classes, like choosing a particular seat with different privileges at the company’s decision-making table.
