Employee Stock Purchase Plan financial
"under the issuer's Employee Stock Purchase Plan ("ESPP")"
An employee stock purchase plan is a company program that lets workers buy shares through small payroll deductions, often at a discount to the market price and after a set offering period. Think of it like a workplace savings plan that turns into ownership: it encourages employees to share in the company’s success and can create predictable buying or selling of stock that investors watch because it affects supply, demand and employee incentives.
Long-Term Incentive ("LTI") Bonus Plan financial
"under the issuer's Long-Term Incentive ("LTI") Bonus Plan"
Equity Linked Notes financial
"The Equity Linked Notes are issued by UBS AG"
worst-performing basket component financial
"closing price of the worst-performing basket component"
strike price financial
"at a strike price of 213.2515 per American Depositary Share"
The strike price is the fixed price at which an option gives its holder the right to buy or sell an underlying stock. Think of it like a coupon that lets you transact at a pre-agreed price regardless of the market; for investors it determines whether an option will be profitable, influences potential gains or losses, and is a key factor in the option’s market value and risk profile.
