CASH ON HAND literally means coin, currency, and cash items on hand. It is not possible to have negative cash on hand.
ZERO COUPON BONDS are bonds priced at a large discount from face value. The bonds mature at full face value so the difference between the original issue price and the face value represents interest income. The issuer of the zero coupon bond saves on cash flow since the interest isnt paid out until the end of the bond holding period.
MARKET MAKERS is one of the major differences between The NASDAQ Stock Market and other major markets in the U.S. is NASDAQ's structure of competing Market Makers. Market Makers are NASDAQ member firms that use their own capital, research, retail and/or systems resources to represent a stock and compete with each other to buy and sell the stocks they represent. Each Market Maker competes for customer order flow by displaying buy and sell quotations for a guaranteed number of shares. Once an order is received, the Market Maker will immediately purchase for or sell from its own inventory, or seek the other side of the trade until it is executed, often in a matter of seconds.
