restricted stock units ("RSUs") financial
"Includes 12,375,000 unvested restricted stock units ("RSUs"), each with respect to one ordinary share"
Restricted stock units (RSUs) are a company promise to give an employee shares of stock (or cash equivalent) in the future, but only after certain conditions—usually staying with the company for a set time or hitting performance goals—are met. Investors watch RSUs because when they vest they increase the number of shares outstanding and can lead insiders to sell shares, affecting share price, company dilution and the true cost of employee pay.
American Depositary Shares financial
"The Ordinary Shares may be represented by American Depositary Shares, each of which currently represents 2,000 Ordinary Shares."
American depositary shares (ADSs) are a way for investors in the United States to buy shares of foreign companies without dealing with international markets directly. They represent ownership in a foreign company's stock and are traded on U.S. stock exchanges, making it easier for American investors to buy, sell, and own parts of companies from around the world.
