Ex-Coupon
Ex-coupon is a bond or preferred stock that does not include the interest payment or dividend when purchased or sold. If the debt security is purchased on or after the ex-coupon date, the seller retains the right to receive the next due interest payment, and no coupon is included with the bond. A bond that is ex coupon is sold or bought with the knowledge that the investor will not receive the next coupon payment from the bond. If an investor purchases a bond sometime between the last coupon payment and the next coupon payment, s/he will receive the interest as s/he will be the bondholder of record. The price for a bond trading cum-coupon is referred to as the full or dirty price, which is the agreed purchase price plus accrued interest.

What Is Ex-Coupon?
Ex-coupon is a bond or preferred stock that does not include the interest payment or dividend when purchased or sold. A bond that is ex coupon is sold or bought with the knowledge that the investor will not receive the next coupon payment from the bond. The lack of interest payments should be taken into account when purchasing the bond and discounted accordingly.
Ex-coupon is also referred to as ex-interest, and can be compared with a stock that is trading ex-dividend.



Understanding Ex-Coupon
The period when coupon payments are made to bondholders is disclosed in the bond indenture at the time of issuance. Some bonds pay interest payments annually, others do so semi-annually, quarterly, or monthly. The coupon interest is paid to the bondholder of record. If an investor purchases a bond sometime between the last coupon payment and the next coupon payment, s/he will receive the interest as s/he will be the bondholder of record. The amount of interest over this period that will be credited to the buyer is called the accrued interest.
However, since the buyer does not earn all of the interest accrued over this period, s/he must pay the bond seller the portion of the interest that the seller earned before selling the bond.
Ex-Coupon Date
The ex-coupon date can be defined as the date by which the trade must occur if the buyer is to receive the upcoming coupon. The ex-coupon date is the first day the bond starts trading without the coupon attached to it. If the debt security is purchased on or after the ex-coupon date, the seller retains the right to receive the next due interest payment, and no coupon is included with the bond. Therefore, the investor must buy or sell the asset before the ex-coupon date to get it with a coupon linked to it.
Example of Ex-Coupon
For example, assume a bond has a fixed coupon that is to be paid semi-annually on June 1 and December 1 every year. If a bondholder sells this bond on October 1, the buyer receives the coupon payment on the next scheduled coupon date, December 1. In this case, the buyer must pay the seller the interest accrued from June 1 to October 1. This interest is embedded in the purchase price of the bond.
Ex-Coupon vs. Cum-Coupon
The purchase price of the bond can take two forms – cum-coupon and ex-coupon. In the United States, bonds always trade cum-coupon, that is, with coupon. The price for a bond trading cum-coupon is referred to as the full or dirty price, which is the agreed purchase price plus accrued interest.
Some bond markets outside of the U.S. trade ex-coupon that is, without the coupon. Buyers of these bonds only pay the agreed purchase price for the bond (the clean price) and forego the next coupon payment. The seller collects and keeps the next interest due after the sale since s/he is registered as the holder of the bond on that date. However, since the buyer will own the bond during a small fraction of the coupon period, the seller must pay him the interest that accrues during that brief period.
