The range of corporate bonds issued each year allows investors to tailor a bond portfolio around their specific needs. The various types of corporate bonds offer different risk levels, as well as varying yields and payment schedules.
Fixed-rate coupons
The most common form of corporate bond is one that has a stated coupon that remains fixed throughout the bond's life. It represents the annual interest rate, usually paid in two installments every six months, although some bonds pay annually, quarterly, or monthly. The payment amount is calculated as a percentage of the par value, regardless of the purchase price or current market value. With corporate bonds, one bond represents $1,000 par value, so a 5% fixed-rate coupon will pay $50 per bond annually ($1,000 × 5%). The payment cycle is not necessarily aligned to the calendar year; it begins on the "Dated Date," which is either on or soon after the bond's issue date, and ends on the bond's maturity date, when the final coupon and return of principal payment are paid.
Investment grade vs. non-investment grade (high yield)
Corporate bonds are generally rated by one or more of the three primary ratings agencies: Standard & Poor's, Moody's, and Fitch. These firms base their ratings on the bond issuer's financial health and likely ability to make interest payments and return the bondholders' principal. Rated bonds fall into one of two categories: investment grade or non-investment grade (also known as high yield). Investment grade bonds are considered to be lower risk and, therefore, generally pay lower interest rates than non-investment grade bonds, though some are more highly rated than others within the category. Non-investment grade bonds are considered to be higher risk or speculative investments. The higher yield reflects an increased risk of default. A company's financial health can change, and when it does, its bonds' ratings may change as well. So an investment grade bond could become non-investment grade over time and vice versa.
Zero-coupon
Zero-coupon corporate bonds are issued at a discount from face value (par), with the full value, including imputed interest, paid at maturity. Interest is taxable, even though no actual payments are made. Prices of zero-coupon bonds tend to be more volatile than bonds that make regular interest payments.
Callable and puttable
The issuer of a callable corporate bond maintains the right to redeem the security on a set date prior to maturity and pay back the bond's owner either par (full) value or a percentage of par value. The call schedule lists the precise call dates of when an issuer may choose to pay back the bonds and the price at which they will do so. The callable price is generally expressed as a percent of par value, but other all-price quotation methods exist.
With a puttable security, or put option, the investor has the right to put the security back to the issuer, again at a set date or a trigger event prior to maturity. A common example is the "survivor's option," whereby if the owner of the bond dies, the heirs have the ability to put back the bond to the issuer and typically receive par value in return.
Step-up
Interest on step-up securities is paid at a fixed rate until the call date, at which time the coupon increases if the bond is not called.
Step-down
Interest on step-down securities is paid at a fixed rate until the call date, at which time the coupon decreases if the bond is not called.
Floating-rate
The coupon on a floating-rate corporate bond changes in relationship to a predetermined benchmark, such as the spread above the yield on a six-month Treasury or the price of a commodity. This reset can occur multiple times per year. The coupon and benchmark can also have an inverse relationship.
Variable- and adjustable-rate
Variable- and adjustable-rate corporate bonds are similar to floating-rate bonds, except that coupons are tied to a long-term interest rate benchmark and are typically only reset annually.
Convertible bonds*
Convertible bonds can be exchanged for a specified amount of the common stock of the issuing company, although provisions generally restrict when a conversion can take place. While these bonds offer the potential for appreciation of the underlying security, prices may be susceptible to stock market fluctuations.
