What is the meaning of discounting?

To sell at a reduced value; the difference between face value and cash value. Some companies specialize in buying mortgages and real estate contracts (often referred to as paper) at a discount. Often the original lender, wanting to cash out on the loan, will thus sell the mortgage at the current published mortgage discount rate. If the discount rate is 12 percent, for example, the lender could sell a $100, 000 mortgage at 88 percent of its worth ($88, 000 or 12 percent below par).
