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.
