Class A Ordinary Shares financial

"Class A Ordinary Shares granted annually to each non-employee director of Aon plc."

Class A ordinary shares are a type of ownership stake in a company that typically grants voting rights to shareholders, allowing them to have a say in important company decisions. They often come with priority in receiving dividends or profits, making them attractive to investors seeking influence and potential income. These shares help distinguish different levels of ownership and rights within a company's stock structure.

non-employee director financial

"Class A Ordinary Shares granted annually to each non-employee director of Aon plc."

tax-withholding disposition financial

"transaction_action: "tax-withholding disposition" for 186.2350 shares at $315.9500 per share."

A tax-withholding disposition is an event or transaction—such as selling or transferring securities, exercising options, or receiving compensation—that triggers a requirement to hold back part of the payment and remit it to tax authorities. It matters to investors because it reduces the cash they receive immediately and can change the timing and amount of taxable income, like a cashier taking a portion of your sale proceeds to pay taxes before you get the rest.

nominal value financial

"reporting person agreed to pay the issuer the nominal value of US $0.01 per share"

Nominal value is the stated or face amount assigned to a financial instrument — for shares it’s the par value printed on the stock certificate, and for money or returns it can mean the number not adjusted for inflation. Think of it like a price tag on an item versus its buying power: the tag tells you the label, but not how much you can actually buy. Investors care because nominal values affect accounting, legal capital, dividend calculations and comparisons over time when inflation may distort real worth.
