common stock units financial

"Common stock units were accrued under the Martin Marietta Materials, Inc. Common Stock Purchase Plan"

A common stock unit is a tradable ownership interest that represents one or more ordinary shares in a company, giving the holder a stake in profits, a claim on assets after creditors, and usually voting rights on corporate matters. For investors it matters because these units determine how much of the company you own, how much influence you have, and how returns or losses are shared—think of owning slices of a pie that can be increased or diluted by the company’s actions.
