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.
A chalazion will often disappear without treatment in a month or so. 1  The first treatment is to place warm compresses over the eyelid for 10-15 minutes at least four times a day. 2  Use water that is no hotter than you can leave your hand in comfortably.
