Answer:
buying the bill at a discount from the face value to be received at maturity.
Explanation:
Treasury bills also referred to as T-bills are short term financial instruments. T-bills are issued at a discount from the face value or par value of the bill. Therefore, a T-bill which has a face value of $2000 may have a purchase price of $1,500. The investor will buy the T-bill for $1,500 and upon maturity of the instrument, the investor will receive $2000. The difference between the purchase price of $1,500 and the amount received at maturity of $2000 is interest earned by the investor.
