Is a bond quoted at 90 selling at a premium or a discount?

Premium

Fee for insurance coverage, usually paid every year by the insured person. The difference between a bond’s par value and its market value when the market value is more. When bonds are sold at a premium, the yield rate will be lower than the stated (face) rate.

Discount

A fee charged when someone buys a note before maturity. With regard to bonds, a bond sells at a discount if the market value becomes less than the face value.
