sell-to-cover arrangement financial

"Represents ADSs sold pursuant to a mandatory, non-discretionary, sell-to-cover arrangement"

American depositary share financial

"Each American depositary share represents one Class A ordinary share."

An American Depositary Share (ADS) is a U.S.-listed certificate that represents a specified number of shares in a foreign company, held by a custodian bank; it works like a receipt that allows U.S. investors to buy and trade foreign equity on American exchanges without dealing with another country’s markets. Investors care because ADSs make foreign stocks easier to access, improve liquidity and settlement in dollars, and can affect dividend payments, voting rights and regulatory oversight compared with buying the underlying foreign shares directly.

restricted share financial

"Acquired from vested restricted shares."

income tax liabilities financial

"for the purpose of satisfying income tax liabilities incurred upon vesting"
