DEFINITION of 'Market Discount'. The difference between a bond's stated redemption price and its purchase price on the secondary market, if it has been purchased at a price below par.

A chalazion is a small bump in the eyelid caused by a blockage of a tiny oil gland. A chalazion is caused by a blocked duct in one of the meibomian glands. These glands are located in the eyelid directly behind the eyelashes. They produce a thin, oily fluid that lubricates the eye.
A chalazion is an enlargement of a long, thin oil gland in the eyelid that results from an obstruction of the gland opening at the edge of the eyelid. At first, a chalazion looks and feels like a stye: swollen eyelid, pain, and irritation.
