Common Units financial

"redeemed 1500 common units of limited partnership interest ("Common Units") of COPT Defense Properties"

Common units are the basic ownership stakes in a company, limited partnership, or trust that function like common stock: they give holders a claim on profits and often voting rights. Think of them as the ordinary seats at a table—the most directly affected by the business’s success or failure, so they typically offer higher upside but carry greater risk than preferred claims or creditors, which matters to investors evaluating potential return and safety.

limited partnership interest financial

"1500 common units of limited partnership interest ("Common Units") of COPT Defense Properties, L.P."

fair market value financial

"cash equal to the fair market value of such shares"

The price a willing buyer and a willing seller would agree on for an asset or security when neither is under pressure and both have access to the same information. Think of it as the market’s neutral estimate of what something is worth, like the price two neighbors would settle on for a car after comparing similar listings. Investors care because fair market value guides buying and selling decisions, tax reporting, portfolio valuation, and how accurately company assets are reflected in financial statements.

10-day average closing price financial

"based on the 10-day average closing price of the issuer's common shares"
