The Last Closed Trade price displayed reflects the price at which the last trade in this company's security occurred on Forge, and can include secondary trades in any class of the company's security, or trades in units of funds holding the company's securities (the economics of which differ versus direct company ownership). The date displayed reflects the date on which the last trade in this company's security closed on Forge. This may be several weeks after the terms of the trade were agreed upon between the buyer and seller. In case of multiple trades closed on the same date, the price displayed is of either (i) the trade which terms were agreed upon most recently; or (ii) the trade with the higher notional value.
