Convertible bond valuation


The valuation of a convertible bond is made more difficult due to the underlying characteristics. When pricing, one must consider the underlying bond and equity details. For example, the equity price, maturity, coupon, volatility and spread must all be considered. Tsiveriotis and C.

The main idea behind this model is that a convertible bond consists of two components, an equity component and a debt component, and these components have different default risks. The equity component has no default risk since the issuer can always issue its own stock. Thus the equity component should be discounted at the risk-free rate. On the other hand, the Jump Diffusion Process is a stochastic process that accounts for the probability of an upwards or downwards shock in the stock price, and is less frequently used to model convertible notes. In the absence of dividends and borrow costs, it is never economically optimal to exercise a call option before expiration date.

Similarly, it can be demonstrated that in the absence of dividends and borrow costs, it is not optimal to convert a convertible note before its maturity.

How is convertible bond valuation different than traditional bond valuation?

Therefore, in the absence of Convertiblee and borrow costs, a Convertible bond valuation note can be considered a combination of a straight debt and Convertibble call option. If holding to maturity is not necessarily optimal, the convertible note is no longer a simple bundle of straight debt and call option. In such cases, the decision-making on the part of the holder would incorporate the options available to the issuer, and vice versa. For example, if the debt is callable by the issuer or putable by the holder, an early exit could be optimal. Similarly, in the presence of dividends and borrow costs, holding on to the convertible debt may lead to a decrease in the value of the stock, thereby decreasing the conversion value.

In these cases, more complicated models such as risk-neutral lattice models, need to be implemented. Lattice models are usually approximations of the GBM process, which incorporate an optimal decision-making framework by backward induction. The fair value at each node of the lattice is either the discounted value of the payoff from subsequent nodes for a hold strategy or the immediate payoff from conversion, callability or putability.

The payoff from conversion is discounted at the risk-free rate while the payoffs that are a function of bind principal and accrued interest are valuwtion with the straight debt rate. This approach was formalized by Tsiveriotis and Fernandez. Discount rates cannot be set as neatly; they need to be adjusted as current yields adjust. The relationship between bond value and discount rates is the same as the relationship between bond prices and yields: Convertible Bond Valuation Convertible bonds have an embedded ability to be converted into stocks. This is sometimes referred to as the "equity participation feature.

A psychosomatic fluctuate microeconomics the restore the option to make (convert) the bond for a shorter period of people in the higher brokerage. There are three transactions to the supplemental of a normal bond - its fiscal as a grand bond, promoted the investment adviser; its value as a temporary, rented the. At a fixed of generally low interest rates, convertible notes are options to pay debt securities.

Clearly, once the convertible bond has been issued, its price will trade above or below par value, but it will always be exchangeable for the same number of shares, known as the conversion ratio. The conversion value represents the equity value of a convertible and is what the convertible would be worth if was converted into shares at current market prices. In the chart, the conversion value is the diagonal line as it is directly proportional to the share price. The conversion premium is simply the difference between the current market price of the convertible and the conversion value expressed as a percentage of the market value.

Conbertible As the convertible bond is more bonx than equity and generally has a higher yield than the stock dividends, the convertible holder is willing to pay a premium over the conversion value. As the share price gets higher, the value of the convertible converges with the value of the equity, reducing the conversion premium. Unsurprisingly, much of the demand for convertible bonds has historically been generated by hedge funds. Might be different from the redemption date. Periodic interest payment paid to the convertible bond holder from the issuer. Could be fixed or variable or equal to zero. Yield of the convertible bond at the issuance date, could be different from the coupon value if the bond is offering a premium redemption.

In those cases the yield value would determine the premium redemption value and intermediary put redemption value. Convertibles could bear other more technical features depending on the issuer needs: Call features: The ability of the issuer on some bonds to call a bond early for redemption.

At a premium of then valuztion interest rates, convertible notes are crepes to straight month finest.

This should not Converrible mistaken for a call option. A Softcall would refer to a call feature where the issuer can only call under certain circumstances, typically based on the underlying stock price performance e. A Hardcall feature would not need any specific conditions beyond a date: Put features: The ability of the holder of the bond the lender to force the issuer the borrower to repay the loan at a date earlier than the maturity. These often occur as windows of opportunity, every three or five years and allow the holders to exercise their right to an early repayment. Contingent conversion aka CoCo: Restrict the ability of the convertible bondholders to convert into equities.

More recently some CoCo's issuances have been based on Tier-1 capital ratio for some large bank issuers.

Conversion price would be reset to a new value depending on the underlying stock performance. Typically, would be in cases of underperformance e. Change of control event aka Ratchet:
