Restricted Stock Units financial

"The security converts to Marsh & McLennan Companies common stock on a 1-for-1 basis."

Restricted stock units are a type of company reward where employees are promised shares of stock, but they only fully own these shares after meeting certain conditions, like staying with the company for a set time. They matter because they can become valuable assets and are often used to motivate employees to help the company succeed.

1-for-1 basis financial

"The security converts to Marsh & McLennan Companies common stock on a 1-for-1 basis."

vest financial

"These restricted stock units vest in three equal annual installments on May 15, 2027, 2028 and 2029."

A vest is the process by which an employee earns the right to receive certain benefits or ownership interests, such as stock or retirement funds, over time. It’s similar to earning a reward gradually, ensuring that the benefit becomes fully yours only after a set period or meeting specific conditions. This makes it important for investors because it determines when they can actually claim or use those benefits.

Common Stock financial

"The security converts to Marsh & McLennan Companies common stock on a 1-for-1 basis."

It is the most common type of stock traded on markets and can provide income through dividends, as well as potential for value growth. For investors, holding common stock means sharing in the company’s profits and risks.
