Overview of a Fixed-Income Security (Bonds)

Who are the issuers of fixed-income security or bonds?

• Supranational organizations
• Sovereign (national) governments
• Non-sovereign (local) governments
• Quasi-government entities

Credit worthiness of Bonds

Bond issuers can also be classified based on their credit worthiness as judged by credit rating agencies.

Bonds can broadly be categorized as

• investment-grade bonds or
• non-investment grade (or high yield or speculative) bonds.

Maturity of Bonds

Fixed-income securities which, at the time of issuance, are expected to mature in one year or less are known as money market securities.

Fixed-income securities which, at the time of issuance, are expected to mature in more than one year are referred to as capital market securities.

Fixed-income securities which have no stated maturity are known as perpetual bonds.

Par Value

The par value (also known as face value, nominal value, redemption value and maturity value ) of a bond refers to the principal amount that the issuer promises to repay bondholders on the maturity date.

Bond prices are usually quoted as a percentage of the par value.

• When a bond's price is above 100% of par, it is said to be trading at a premium
• When a bond's price is at 100% of par, it is said to be trading at par.
• When a bond's price is below 100% of par, it is said to be trading at a discount.

Coupon Rate and Frequency

The coupon rate (also known as the nominal rate) of a bond refers to the annual interest rate that the issuer promises to pay bondholders until the bond matures.

The amount of interest paid each year by the issuer is known as the coupon, and is calculated by multiplying the coupon rate by the bond's par value.

Zero-coupon (or pure discount) bonds are issued at a discount to par value and redeemed at par (the issuer pays the entire par amount to investors at the maturity date).  The difference between the (discounted) purchase price and the par value is effectively the interest on the loan.

Currency Denomination

Dual currency bonds make coupon payments in one currency and the principal payment at maturity in another currency.

Currency option bonds give bondholders a choice regarding which of the two currencies they would like to receive interest and principal payments in.

Yield Measures

The current yield or running yield equals the bond's annual coupon amount divided by its current price (not par value), expressed as a percentage.

The yield to maturity (YTM) is also known as the yield to redemption or the redemption yield.  It is calculated as the discount rate that equates the present value of a bond's expected future cash flows until maturity to its current price.

Given a set of expected future cash flows, the lower  the YTM or discount rate, the higher the bond's current price.

Given a set of expected future cash flows, the higher the YTM or discount rate, the lower the bond's current price.
