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. Market discount arises when a bond's value on the secondary market decreases after it has been issued, usually because of an increase in interest rates.
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.
Chalazion Symptoms. A chalazion grows more slowly than styes do and if the chalazion becomes large enough, it can interfere with vision as the lump or cyst is very firm and is under the skin of the eyelid. The inflammation as well as the swelling can spread to adjacent areas surrounding the eye.
