4 terms

exercise price or tax liability financial

"delivering or withholding securities"

vesting restrictions financial

"remain subject to vesting restrictions"

Class B Common Stock financial

"convertible into Common Stock at any time on a one-for-one basis"

A class B common stock is one of multiple types of a company’s ordinary shares that carries specific rights—often different voting power or dividend priority—compared with other classes. For investors it matters because those differences affect how much influence you have over company decisions, the income you might receive, and how freely the shares trade; think of it like owning a car with different keys: some keys let you start the engine and open the trunk, others only unlock the door.

Dividend Reinvestment Plan financial

"acquired under the Watsco Inc. Dividend Reinvestment Plan"

A dividend reinvestment plan lets shareholders automatically use cash dividends to buy more shares of the same company instead of receiving the money. It matters to investors because it turns regular payouts into a steady way to grow ownership and take advantage of compound returns—like having your savings automatically buy additional slices of a pie over time—while often reducing transaction costs and smoothing purchase timing.
