Employee Stock Purchase Plan financial
"acquisition of shares of the Issuer's common stock pursuant to the Issuer's 2018 Employee Stock Purchase Plan"
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.
Section 16b-3(c) regulatory
"This transaction is exempt under Section 16b-3(c)."
Depositary Share financial
"Each Depositary Share represents a 1/40th interest in a share of the Issuer's 5.00% Series A Fixed-Rate Non-Cumulative Perpetual Preferred Stock."
A depositary share is a special type of stock that represents ownership in a company but is traded on the stock market like regular shares. It often makes it easier for people to buy and sell shares of companies from other countries or smaller companies that don’t list directly on big exchanges.
Non Qualified Stock Option (Right to Buy) financial
"Non Qualified Stock Option (Right to Buy) ... underlying Security Title Common Stock"
Restricted Share Units financial
"The RSU's were granted pursuant to the Company's 2018 Stock Incentive Plan."
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.
