Key Terms
par value, open market, private transaction
3 terms
par value financial
"Common Stock, par value $0.01 per share"
Par value is the fixed amount printed on a bond or stock that represents its original value when issued. It’s like the face value of a coin or bill—what the issuer promises to pay back or the starting price of a stock—though it often doesn’t change with market prices. It matters because it helps determine certain financial details, like how much the company will pay back at maturity.
open market financial
"Purchase in open market or private transaction"
An open market is a system where buying and selling of goods, services, or financial assets happen freely without restrictions or special controls. For investors, it means they can trade assets easily and quickly, which helps determine fair prices based on supply and demand. This environment encourages transparency and competition, making it easier to buy or sell with confidence.
private transaction financial
"Purchase in open market or private transaction"
A private transaction is the sale or transfer of securities, assets, or ownership stakes carried out directly between a small number of parties rather than on a public exchange. For investors it matters because these deals are less visible and often less liquid than public trades, so pricing can be harder to verify, the investment can be harder to sell quickly, and buyers or sellers may gain strategic advantages not available in open markets — like negotiated terms similar to a private garage sale versus a crowded marketplace.
