Restricted Share Units financial

"Restricted Share Units (RSUs) issued in lieu of cash dividends"

Restricted share units (RSUs) are a promise from a company to give an employee or service provider actual shares or cash equal to the shares after certain conditions are met, typically staying with the company for a set time or hitting performance targets. Think of them like a time-locked gift card that becomes usable only after you’ve earned it. For investors, RSUs matter because they align employee incentives with company performance and can increase the number of shares outstanding over time, diluting existing ownership and affecting earnings per share.

unvested shares financial

"dividends on unvested shares becomes payable"

installments financial

"in installments beginning upon the termination"

Installments are a series of scheduled partial payments that together cover a larger amount owed or due, like paying for a purchase or loan in weekly or monthly pieces rather than all at once. For investors, installments matter because they change when cash moves between parties, affect a company’s or counterparty’s short-term cash flow and risk of missed payments, and can influence valuation or perceived financial stability much like spreading the cost of a car over monthly payments.
