Municipal Bond Underwriting Spreads - How Underwriters Make Money


The Underwriting Spread

In a new offering of municipal bonds, underwriters make money from the "underwriting spread."  The underwriting spread (underwriter spread or underwriting fee) is the difference between the price at which a bond issue is bought (the purchase paid) and the price at which the bonds are sold to investors. 

An underwriting spread can be obtained using a discount, par or premium pricing approach (or a combination of the three pricing methods).  Generally, the pricing approach does not affect the underwriter's compensation.(1)
The underwriter will establish a purchase price for the bonds and interest rates that result in the desired level of compensation.

Without knowing how bonds are priced, it is not possible to know what compensation the underwriter is receiving. For example, an underwriter that purchases a  bond issue at a discount of 1/2% (purchase price of 99.5%) does not necessarily obtain a 1/2% fee. The compensation will be more than 1/2% if the bonds are sold at a premium (a price higher than 100%).  A discount of 1/2% coupled will reoffering premiums totaling 1/2% would net the underwriter a total spread of 1%.  Stated differently, if the underwriter purchases the bonds 99.5% and sells the bonds at 100.5% the compensation is 1%. 

Municipal Bond Yields and Rates

The underwriting spread affects the bond issue price and rates with the constant variable being the current market yield.   Current market yield refers to the rate of return required to entice an investor to purchase a bond for a particular duration of time. For a new bond offering, when bonds are sold to the public at a price of 100%, the rate on the bonds and the yields are the same as indicated in the following example. 

Year

Rate Yield Price
1    3.35%    3.35%    100.000%
2 3.40 3.40 100.000
3 3.50 3.50 100.000
4 3.60 3.60 100.000
5 3.70 3.70 100.000

When bonds are sold to the public at a price other than 100%, the rate on the bonds (and the price at which the bonds are sold) must be adjusted so that investors obtain the same rate of return (yield). In setting the rates on individual maturities of a bond issue, the underwriter takes the following into account (i) market yields, (ii) the prices required to obtain the desired underwriting spread, and (iii) prices that will be attractive to investors (not too high or too low).

Based on the same market yields as shown above, the following table indicates the price at which the bonds are sold when the rate on all of the bonds is 3.6%.

4 3.60 3.60 100.000
5 3.60 3.70   99.547


Bond Pricing Examples

Four examples are set forth below to illustrate how different pricing approaches result in a 1% underwriter spread. In addition, the four examples show how different pricing approaches affect the amount of funds obtained by the issuer, interest rates and debt service.  The four examples are based on the following:           

                 The same pricing approach is applied to each maturity of bonds. (Often different pricing
                   approaches are applied to individual maturities of a single bond issue.)

                 The issuer sells $10,000,000 principal amount of bonds (regardless of pricing approach) and the
                   principal amounts maturing in each year remain constant.

                 The bonds mature over a 5 year term.

                 The underwriter establishes rates and purchase prices that result in compensation of 1%
                   (a 1% underwriting spread).

                 The market yields at the time of the sale are as follows:

Year

1    3.350%
2 3.400
3 3.500
4 3.600

Comparison of Four Pricing Alternatives

The following table summarizes the results from the examples above.  Note that in each example the underwriter obtains approximately $100,000 (1% of the principal amount of the issue); however the amount of funds received by the issuer and the debt service paid over the life of the bond issue varies based on the pricing method used to obtain the underwriter's spread.

Purchase Price/Sale Price Bought at Discount/Sold At Discount
(Original Issue Discount)
Bought at Discount/Sold at Par Bought at Par/Sold at Premium Bought at Premium/Sold at Premium

Underwriter's Compensation

$100,003 $100,000 $100,000 $99,998

Summary

Underwriters are compensated through an underwriting spread that can be obtained through a number of pricing combinations.  The spread is the difference between the price at which a bond issue is purchased and the price at which the bonds are sold to investors. Without knowing the price at which bonds are sold an issuer can not know how much the underwriter was compensated.  Without knowing the price at which the bonds are sold, an underwriter may be compensated more than had been intended. In addition, because the pricing approach affects the funds received by the issuer and the total debt service paid, it is important that issuers understand the mechanics of pricing or seek pricing assistance from an independent financial advisor.

_________
(1)   An underwriter may set a higher level of compensation if the issuer selects a pricing strategy that is not consistent with the pricing approach desired by the underwriter.
(2)   Municipal bond rates are generally in multiples of 1/20 or 1/8 of 1%.  Some of the rates set forth above are for purposes of illustrating pricing rather than indicative of true market rates.
