American Depositary Shares financial

"Ordinary Shares are represented by American Depositary Shares ("ADSs")."

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.

exchange agreement financial

"the Issuer and the Reporting Person, entered into an exchange agreement, pursuant to which"

A written deal in which two parties agree to swap assets, securities or obligations under set terms—think of it as a formal swap or trade contract. For investors it matters because such agreements can change who owns what, alter a company’s capital structure, affect future cash flows or dilute existing shares, and therefore influence value and risk in a straightforward, contract-driven way.

Outstanding Debt financial

"accrued interest outstanding ("Outstanding Debt") owed in connection with a note"
