Convertible Bonds

Convertible bonds are issued by stock corporations. The investor has the right to swap the bond for a fixed quantity of the stock of the issuing corporation within a particular time limit.

The investor swaps the bond for stock if the value of the stock is greater than the nominal value of the bond. Convertible bonds can therefore be split into a bond and a call option on the underlying stock.

In order to valuate convertible bonds, you must create them as generic transactions.

Prerequisite

You have created the security classes for the bond and the stock in Treasury. A financial object exists for the bond.

Note Note

Ensure that you make an entry in the Nomin. per TU field in the basic data of the bond class. By doing so, you specify the amount of the nominal volume for which the option in the generic transaction is valid.

Procedure

To depict a convertible bond as a generic transaction, create the following elementary transaction hierarchy:

This graphic is explained in the accompanying text.

Create the hierarchy as follows: (The following depicts the transaction from the perspective of the investor.)

Create a new generic transaction with category 9 (class supplement). In the master data, enter the ID of the bond created in Treasury. See Editing Generic Transactions for the procedure.
1. .
In the dialog structure, select the first elementary transaction and assign to it transaction form 300 (complex class) .

The system displays a tab page.

Enter the issue date of the bond in the Start of term field.
Create a transaction with transaction form 402 (reference to ID number) under the Complex Class elementary transaction. To do this, select the Complex Class elementary transaction in the dialog structure and choose Create Elementary Trans.: Next Level . Select the new elementary transaction and assign to it transaction form 402.

The system displays a tab page.

Enter the object number of the bond in the ID Number field. You can use input help to select the transaction.
Create a transaction with transaction form 61 (OTC option) under the Complex Class elementary transaction. (Proceed as for step 3).

The system displays three tab pages.

Enter the following information on the Header Information tab page:
- Start of term field.
  
  Issue date of the bond
- Notification By field
  
  Due date of bond
- Purchase/Sale field
  
  Set the indicator to Purchase/Investment Made .
  
  On the Options Information tab page, flag the option as a standard option with European exercise and, in particular, as a call option. Enter the following information:
- Strike Currency field
  
  Currency of the bond
- Delivery of Underlying field
  
  Due date of bond
- Quotation of Underlying field
  
  Direct quotation
  
  You do not need to make any entries on the Cash Flow tab page.
Create a transaction with transaction form 10 (stock) under the OTC Option elementary transaction. (Proceed as for step 3).

The system displays the tab page for the header information.

Enter the security ID number, the exchange, enter Direct quotation quotation type, and enter the number of units. Flag the transaction as a spot transaction and a purchase.
Choose Back and then Save.

Result

You have created the convertible bond as a generic transaction.

The system does not generate a financial object when you save even if automatic financial object integration is active. You have already created a financial object for the bond.

Example

Interest is calculated on a convertible bond for EUR 1,000 with 2%, which runs from 01/01/2002 to 01/01/2007. The bond class gives the owner of the bond the right to convert EUR 1,000 of the class into 20 units of company A’s stock at the end of the term. Company A’s stock has the security ID number 803200. The convertible bond has the security ID number 803260.

From the investor’s perspective, this class can be split into a bond with the corresponding interest and repayment structure, and the purchase of a call option. The call option is of the European exercise type, its term end is 01/01/2007, and its strike is EUR 1,000 for 20 units of stock.

The following tables contain the entries that you would have to make for the generic transaction and the elementary transactions for this example. As the generic transaction just references the bond, you do not need to enter the interest rate of 2% when you create the generic transaction.
