dividend equivalents financial

"Acquired with dividend equivalents credited to the reporting person's account"

Payments tied to employee or contractor equity awards that mirror the cash dividends paid on the company’s stock; they give the holder the same economic benefit as owning the shares without transferring actual shares—often paid in cash or additional award units when the award becomes payable. Investors care because these payments affect a company’s compensation costs, cash flow and potential share dilution, and they signal how management is being rewarded and aligned with shareholders.

Directors Stock Compensation Plan financial

"under the Marsh & McLennan Companies Directors Stock Compensation Plan"

Rule 10b5-1 regulatory

"The filing’s Rule 10b5-1 checkbox is not checked"

Rule 10b5-1 is a regulation that allows company insiders to buy or sell their shares at predetermined times, even if they have access to non-public information. It acts like setting a schedule in advance for transactions, helping prevent accusations of unfair trading. This rule provides a way for insiders to plan trades transparently, giving investors confidence that these transactions are not based on hidden information.
