The prospectus of a bond issuep p Indenture or trust deed: bond agreement between borrower and a trust company

Trust company: a company that represents the bondholders and makes sure Trust company: a company that represents the bondholders and makes sure that the terms of the indenture are enforced

Main elements: Principal or face value and coupon rates (interests), and their dates Principal: nominal amount for calculating interest, typically repaid on due date Coupon: for a given coupon rate (0 for zero-coupon or pure discount bonds): Coupon: for a given coupon rate (0 for zero coupon or pure discount bonds):

Example: $1000 bond with a 10% coupon rate with semi annual paymentsyearper coupons ofnumber

principal x ratecupon CPN

Example: $1000 bond with a 10% coupon rate with semi-annual payments, pay coupons: $1000 x 0.10 / 2 = $50 every 6 months

Types of bonds:yp Registered bond - a bond in which the Company's records show ownership

and interest and principal are paid directly to each owner Bearer bonds - the bond holder must send in coupons to claim interest and

Albert Banal-Estanol Direcció Financera II - Chapter 3

must send a certificate to claim the final payment of principal

Types of corporate debtyp p Secured debt

S ifi l d d ll l h b dh ld h di l i i h Specific assets are pledged as collateral that bondholders have a direct claim to in the event of bankruptcy

Example1: mortgage bonds (property as collateral)

E ample 2 Asset backed bonds (an kind of asset) Example 2: Asset-backed bonds (any kind of asset) Unsecured debt:

In the event of bankruptcy, bondholders have a claim to only the assets that are not already pledged as collateral on other debtpledged as collateral on other debt

Examples: Notes (maturities<10 years) and debentures (longer)

Tranches: Different classes of securities that comprise a single bond issue All classes of securities are paid from the same cash flow source

SeniorityA b dh ld ’ i it i l i i t t l d i th d bt A bondholder’s priority in claiming assets not already securing other debt

Most debenture issues contain clauses restricting the company from issuing new debt with equal or higher priority than existing debt

Zero-coupon bondsp

Special type of bonds: They don’t pay coupons and therefore are always sold at a discount (lower

price than the principal), and are also called pure discount bond Treasury Bills: U.S. government bonds with maturities of less than one year Treasury Bills: U.S. government bonds with maturities of less than one year

The YTM of a zero-coupon bond maturing in n years, can be written as:1

Since a safe bond without coupon maturing in n years gives an interest without risk in that period YTM must be equal to the risk-free interest rate

P

without risk in that period, YTM must be equal to the risk-free interest rate What if not?

Sensitivity and its measurementy• We have that ...

• Long-term bonds are more sensitive to changes in interest rates than short-term bonds

• Similarly, bonds with higher coupon rates are less sensitive to changes in interest rates because they pay more upfront

• Duration of a bond:

• measures the price sensitivity to changes in interest rates

• ponders the years for their contribution to total present valueponders the years for their contribution to total present value

• average number of years of the discounted cash flows

Valuing safe bonds using arbitrageg g g

So far we focused on the relationship between price and YTM So far, we focused on the relationship between price and YTM Here, we should look at the price and YTM using similar bonds of known price

Price and yield of any safe bond with coupon? Price and yield of any safe bond with coupon? By arbitrage, (government) spot interest rates should give same return on cash flows Replicate cash flows of a coupon bond using zero coupon-spot interest rates

For example ... $ 1,000 bond paying 10% per year is equivalent to a portfolio of 3 zero-coupon bonds

Albert Banal-Estanol Direcció Financera II - Chapter 3

Where do we get the spot interest rates from?

Risky bond valuationRisky bond valuation

S f h l d i k f b d ( T bill ) So far we have valued risk-free bonds (e.g. Treasury bills)

Other bonds, like corporate bonds, issuer can default (credit risk):

The risk of insolvency changes price of a bond and YTM. How?

We should see that…

Investors pay less for bonds with credit risk than they would for an otherwise identical default-free bond

The yield of bonds with credit risk will be higher than that of otherwise identical default-free bonds

pay dividends, the level of further indebtedness or specify that the issuer must maintain a minimum amount of working capitalissuer must maintain a minimum amount of working capital

Repayment provisions:

Issuer can repurchase a fraction of the outstanding bonds in the Issuer can repurchase a fraction of the outstanding bonds in the market or make a tender offer for the entire issue

For callable bonds, exercise the call provision

Callable bonds:

Issuers have the right (but not the obligation) to retire all outstanding g ( g ) gbonds on (or after) a specific date (the call date), for the call price

Call a bond issue if interest rates lower -> lower price than in market!

What determines the shape of the yield curve?

Basically the interest rates expectations: Basically the interest rates expectations: Suppose short-term are equal to long-term rates (curve is flat) If (all) interest rates are expected to rise in the future: invest short-term and reinvest later! Nobody would want to invest long term, so long-term rates should rise (curve increasing) And if they are expected to fall ... that would happen?

Decreasing (“inverted”) yield curve: It is expected that interest rates fall in future

As rates fall as the economy worsens is a negative projection As rates fall as the economy worsens is a negative projection

Increasing (“steep”) yield curve:g ( p ) y It is expected that interest rates will rise in future It can be interpreted as a positive economic projection

The liquidity preference theoryq y p y

The expectations theory leaves out any type of riskp y y yp

Bond prices have some volatility, and this causes some risk, higher for longer-term bonds (creates a liquidity premium!)

Uncertainty about inflation is one of those risks (affecting nominal interest rate expectations). Therefore, if there is more uncertainty about inflation (or in ti f l til i fl ti ) li idit i ill b hi h d ill b ttimes of volatile inflation) liquidity premium will be higher and will be steeper

Investors incur extra risk (interest rate, not insolvency) to maintain long-term bonds so they demand a premium for liquidity Curve will normally be upwardbonds, so they demand a premium for liquidity. Curve will normally be upward sloping
