Introduction to Bonds Payable
Bonds are a form of long-term debt. You might think of a bond as an IOU issued by a corporation and
purchased by an investor for cash. The corporation issuing the bond is borrowing money from an investor
who becomes a lender and bondholder.
A bond is a formal contract that requires the issuing corporation to pay the bondholders
1. Interest every six months based on the bonds stated interest rate, and2. The principal or face amount on the bonds maturity date.
There are two significant advantages for a corporation to issue bonds instead of common stock:
1. Bonds will not dilute the ownership interest of the stockholders, and2. Bonds have a lower cost than common stock.
Bonds have a lower cost than common stock because of the bonds formal contract to pay the interest
and principal payments to the bondholders and to adhere to other conditions. A second reason for bonds
having a lower cost is that the bond interest paid by the issuing corporation is deductible on its U.S.
income tax return, whereas dividends are not tax deductible.
The market value of an existing bond will fluctuate with changes in the market interest rates and with
changes in the financial condition of the corporation that issued the bond. For example, an existing bond
that promises to pay 9% interest for the next 20 years will become less valuable if market interest rates
rise to 10%. Likewise, a 9% bond will become more valuable if market interest rates decrease to 8%.
When the financial condition of the issuing corporation deteriorates, the market value of the bond is likely
to decline as well.
Present value calculations are used to determine a bonds market value and to calculate the true or
effective interest rate paid by the corporation and earned by the investor. Present value calculations
discount a bonds fixed cash payments of interest and principal by the market interest rate for the bond.
Bond Interest and Principal Payments
When a corporation issues a bond, it promises to pay the bondholder
1. Interest every six months at the bond's stated interest rate, and2. The principal or face amount when the bond comes due at its maturity date.
Bond Interest Payments
Normally, a bonds interest payments occur semiannually. This means that the corporation issuing a bond
will pay to the bondholders one-half of the annual interest at the end of each six-month period as long as
the bond is outstanding. The formula for calculating the semiannual interest payments is:
Face Amount of the Bond x Stated Annual Interest Rate x 6/12 of a Year
The following terms mean the same as a bonds statedinterest rate:
face interest rate nominalinterest rate coupon interest rate contractualinterest rate
Throughout our explanation of bonds payable we will use the term stated interest rate or stated rate.
Usually a bonds stated interest rate is fixed or locked-in for the life of the bond.

Bond Principal Payment
A bonds principal payment is the dollar amount that appears on the face of a bond. This is the amount
that the issuing corporation must pay to the bondholders on the date that a bond matures or comes due.
Here are some names that refer to a bondsprincipal amount:
face value paror par value maturityvalue or maturity amount statedvalue
Throughout our explanation we will use these terms interchangeably. In addition, we assume that the
bonds principal amount will be due on a single date.
Timeline for Interest and Principal Payments
It is helpful to prepare a timeline to visualize the cash payments that a corporation promises to pay its
bondholders. The following timeline presents the cash payments of interest and principal for a 9%
$100,000 bond maturing in 5 years:
Interest: $4,500 $4,500 $4,500 $4,500 $4,500 $4,500
Principal: $100,000
.....
6 months 6 months 6 months 6 months 6 months
0 Period No. 1 2 3 4 9 10
As the timeline indicates, the corporation will pay its bondholders 10 semiannual interest payments of
$4,500
($100,000 x 9% x 6/12 of a year). Each of the interest payments occurs at the end of each of the 10 six-
month time periods. When the bond matures at the end of the 10th six-month period, the corporation mustmake the $100,000 principal payment to its bondholders.
Keep in mind that a bonds stated cash amountsthe ones shown in our timelinewill not change during
the life of the bond.
Accrued Interest
Since the corporation issuing a bond is required to pay interest, and since the interest is paid on only two
dates per year, the interest on a bond will be accruing daily. This means for each day that a bond is
outstanding, the corporation will incur one day of interest expense and will have a liability for the interest it
has incurred but has not paid. If the corporation has issued a 9% $100,000 bond, then each day it will
have interest expense of $24.66 ($100,000 x 9% x 1/365).
If the corporation issues monthly financial statements, then each month it needs to report $750 ($100,000
x 9% x 1/12) of interest expense. The corporation usually does this with the following monthly adjusting
entry:Interest Expense 750
Interest Payable 750

While the issuing corporation is incurring interest expense of $24.66 per day on the 9% $100,000 bond,
the bondholders will be earning interest revenue of $24.66 per day. With bondholders buying and selling
their bond investments on any given day, there needs to be a mechanism to compensate each
bondholder for the interest earned during the days a bond was held. The accepted technique is for the
buyer of a bond to pay the seller of the bond the amount of interest that has accrued as of the date of the
sale. For example, if a 9% $100,000 bond has a date of January 1, 2010 and it is sold on January 31,
2010, the buyer of the bond is required to pay the seller of the bond one months interest amounting to
$750 ($100,000 x 9% x 1/12).
Bonds Issued at Par with No Accrued Interest
If a corporation issues a bond on January 1, 2010 and the bond has a date of January 1, 2010 there will
be no accrued interest on the bond when it is issued. If the investor pays the corporation the face amount
of the bond, the bond is said to have been issued at parorat 100meaning 100% of the bonds face
valueplus any accrued interest. (As we will see later, it is possible for a new bond to be issued after the
date of the bondand therefore to have accrued interest. In addition a bond might be sold by the issuing
corporation for more or less than its face value.)
Lets assume that on January 1, 2010 a corporation issues a 9% $100,000 bond at its face amount. The
bond is dated January 1, 2010 and requires interest payments on each June 30 and December 31 until
the bond matures at the end of 5 years. Each semiannual interest payment will be $4,500 ($100,000 x 9%x 6/12). The corporation is also required to pay $100,000 of principal to the bondholders on the bond's
maturity date of December 31, 2014.
Since the bond was issued/sold for 100% of its face amount and since there is no accrued interest to be
paid by the buyer of the bond, the issuing corporation will make the following journal entry:Jan 1, 2010 Cash 100,000
Bonds Payable 100,000
The following timeline shows the future cash payments that the corporation must make to the
bondholders:
Interest: $4,500 $4,500 $4,500 $4,500 $4,500 $4,500Principal: $100,000

Journal Entries for Interest Expense Annual Financial Statements
If the corporation issuing the above bond has an accounting year ending on December 31, the
corporation will incur twelve months of interest expense in each of the years that the bonds are
outstanding. In other words, under the accrual basis of accounting, this bond will require the issuing
corporation to report Interest Expense of $9,000 ($100,000 x 9%) per year.
If the corporation issues only annualfinancial statements, the interest expense can be recorded at the
time of its semiannual interest payments, as shown in the following journal entries for the year 2010:Jun 30, 2010 Interest Expense 4,500
Cash 4,500
Dec 31, 2010 Interest Expense 4,500

Journal Entries for Interest Expense Monthly Financial Statements
If the corporation issues monthlyfinancial statements, it must report interest expense of $750 ($100,000 x
9% x 1/12) on each of its monthly income statements. It must also report a current liability on its balance
sheet for the amount of interest that it has incurred but has not yet paid. This is accomplished by
recording an accrual adjusting entry at the end of each month. In addition there will be an entry on June
30 and on December 31 for the required interest that was actually paid to the bondholders. The 14 journal
entries pertaining to the corporations bond interest during the year 2010 will be:Jan 31, 2010 Interest Expense 750

The journal entries for the years 2011 through 2014 will have the same accounts and amounts.
Bonds Issued at Par with Accrued Interest
If a corporation has prepared a bond with a date of January 1, 2010 but delays issuing the bond until
February 1, the investors buying the bonds on February 1 will have to pay the issuing corporation one
month of accrued interest. (The delay may have been caused by a turbulent financial market or some
other situation.)
7/29/2019 Introduction to Bonds Payable F
5/32
Lets illustrate this scenario with a corporation preparing to issue a 9% $100,000 bond dated January 1,
2010. The bond will mature in 5 years and requires interest payments on June 30 and December 31 of
each year until December 31, 2014. The bond is issued on February 1 at its par value plus accrued
interest.
Since the bond was sold to investors at par, the issuing corporation will receive 100% of the bonds face
value plus one month of accrued interest. The accrued interest amounts to $750 ($100,000 x 9% x 1/12).In total the issuing corporation will receive $100,750. The journal entry for this transaction is:Feb 1, 2010 Cash 100,750
Bonds Payable 100,000
Interest Payable 750
Note that the total amount received is debited to the Cash account and the bond's face amount is credited
to Bonds Payable. The $750 received by the corporation for the accrued interest is credited to Interest
Payable. The corporation is receiving the $750 because the corporation is required to pay the
bondholders $4,500 ($100,000 x 9% x 6/12) on June 30. The difference between the $4,500 paid on June
30 and the $750 received on February 1, 2010 is $3,750equal to five months of interest for the months
of February through June: $100,000 x 9% x 5/12.
Journal Entries for Interest Expense Annual Financial StatementsIf a corporation that is planning to issue a bond dated January 1, 2010 delays issuing the bond until
February 1, the corporation will not have interest expense during January. Assuming the corporation has
an accounting year that ends on December 31, it will have eleven months of interest expense during the
year 2010. During each of the subsequent years 2011, 2012, 2013, and 2014 the corporation will have
twelve months of interest expense equal to $9,000 ($100,000 x 9% x 12/12).
If the corporation issues only annualfinancial statements, its journal entries for its interest payments
during the year 2010 will be:Jun 30, 2010 Interest Expense 3,750
Interest Payable 750
Cash 4,500
Dec 31, 2010 Interest Expense 4,500
Cash 4,500
Note that the total amount of interest expense in 2010 will be $8,250 ($3,750 recorded on June 30 +
$4,500 recorded on December 31). This amount of interest expense for February 1 through December
31, 2010 is confirmed by the following calculation: $100,000 x 9% x 11/12 = $8,250.
In the year 2011, the journal entries will be:Jun 30, 2011 Interest Expense 4,500
Cash 4,500
Dec 31, 2011 Interest Expense 4,500
Cash 4,500
In the year 2011, the interest expense will be $9,000 ($4,500 + $4,500 = $9,000; or $100,000 x 9% =
$9,000) because the bond will be outstanding for a full year. The entries will be similar for the years 2012,
2013, and 2014.

Journal Entries for Interest Expense Monthly Financial Statements
If monthly financial statements are issued by the corporation, the following journal entries are needed in
the year 2010 (including the entry when the bonds were issued on February 1, 2010):
Feb 1, 2010 Cash 100,750

Note that in 2010 the corporation's entries included 11 monthly adjusting entries to accrue $750 of
interest expense plus the June 30 and December 31 entries to record the semiannual interest payments.
As a result of these journal entries, each monthly income statement will report one month of interest
expense and the balance sheet will report a current liability for the amount of interest incurred by the
corporation but not yet paid to the bondholders.
In each of the years 2011 through 2014 there will be 12 monthly entries of $750 each plus the June 30
and December 31 entries for the $4,500 interest payments.

Market Interest Rates and Bond Prices
Once a bond is issued the issuing corporation must pay to the bondholders the bonds stated interest for
the life of the bond. While the bonds stated interest rate will not change, the market interest rate will be
constantly changingdue to global events, perceptions about inflation, and many other factors which occur
both inside and outside of the corporation.
The following terms are often used to mean marketinterest rate:
effective interest rate yieldto maturity discountrate desiredrate
When Market Interest Rates Increase
Market interest rates are likely to increase when bond investors believe that inflation will occur.As a result, bond investors will demand to earn higher interest rates. The investors fear that whentheir bond investment matures, they will be repaid with dollars of significantly less purchasing
power.
Lets examine the effects of higher market interest rates on an existing bond by first assuming that a
corporation issued a 9% $100,000 bond when the market interest rate was also 9%. Since the bond's
stated interest rate of 9% was the same as the market interest rate of 9%, the bond should have sold for
$100,000.
Next, lets assume that after the bond had been sold to investors, the market interest rate increased to
10%. The issuing corporation is required to pay only $4,500 of interest every six months as promised in
its bond agreement ($100,000 x 9% x 6/12) and the bondholder is required to accept $4,500 every six
months. However, the market will demand that new bonds of $100,000 pay $5,000 every six months
(market interest rate of 10% x $100,000 x 6/12 of a year). The existing bonds semiannual interest of
$4,500 is $500 less than the interest required from a new bond. Obviously the existing bond paying 9%interest in a market that requires 10% will see its value decline.
An existing bonds market value will decrease when the market interest rates increase. The reason is that
an existing bonds fixed interest payments are smaller than the interest payments now demanded by the
market.
When Market Interest Rates Decrease
Market interest rates are likely to decrease when there is a slowdown in economic activity. In other words,
the loss of purchasing power due to inflation is reduced and therefore the risk of owning a bond is
reduced.
Lets examine the effect of a decrease in the market interest rates. First, lets assume that a corporation
issued a 9% $100,000 bond when the market interest rate was also 9% and therefore the bond sold for its
face value of $100,000.
7/29/2019 Introduction to Bonds Payable F
8/32
Next, lets assume that after the bond had been sold to investors, the market interest rate decreased to
8%. The corporation must continue to pay $4,500 of interest every six months as promised in its bond
agreement ($100,000 x 9% x 6/12) and the bondholder will receive $4,500 every six months. Since the
market is now demanding only $4,000 every six months (market interest rate of 8% x $100,000 x 6/12 of
a year) and the existing bond is paying $4,500, the existing bond will become more valuable. In other
words, the additional $500 every six months for the life of the 9% bond will mean the bond will have a
market value that is greater than $100,000.
An existing bonds market value willincrease when the market interest rates decrease. An existing bond
becomes more valuable because its fixed interest payments are larger than the interest payments
currently demanded by the market.
Relationship Between Market Interest Rates and a Bonds Market Value
As we had seen, the market value of an existing bond will move in the opposite direction of the change in
market interest rates.
When market interest rates increase, the market value of an existing bond decreases. When market interest rates decrease, the market value of an existing bond increases.
The relationship between market interest rates and the market value of a bond is referred to asan inverse relationship. Perhaps you have heard or read financial news that stated Bond pricesand bond yields move in opposite directions or Bond prices rallied, lowering their yield... orThe rise in interest rates caused the price of bonds to fall.
If you were the treasurer of a large corporation and could predict interest rates, you would...
Issue bonds prior to market interest rates increasingin order to lock-in smaller interest payments.
If you were an investor and could predict interest rates, you would...
Purchase bonds prior to market interest rates dropping. You would do this in order to receive therelatively high current interest amounts for the life of the bonds. (However, be aware that bondsare often callable by the issuer.)
Sell bonds that you own before market interest rates rise. You would do this because you dontwant to be locked-in to your bonds current interest amounts when higher rates and amounts willbe available soon.
Bond Premium with Straight-Line Amortization
When a corporation prepares to issue/sell a bond to investors, the corporation might anticipate that the
appropriate interest rate will be 9%. If the investors are willing to accept the 9% interest rate, the bond willsell for its face value. If however, the market interest rate is less than 9% when the bond is issued, the
corporation will receive more than the face amount of the bond. The amount received for the bond
(excluding accrued interest) that is in excess of the bonds face amount is known as the premium on
bonds payable, bond premium, orpremium.
To illustrate the premium on bonds payable, let's assume that in early December 2009, a corporation has
prepared a $100,000 bond with a stated interest rate of 9% per annum (9% per year). The bond is dated
as of January 1, 2010 and has a maturity date of December 31, 2014. The bond's interest payment dates
are June 30 and December 31 of each year. This means that the corporation will be required to make
semiannual interest payments of $4,500 ($100,000 x 9% x 6/12).

9/32
Let's assume that just prior to selling the bond on January 1, the market interest rate for this bond drops
to 8%. Rather than changing the bond's stated interest rate to 8%, the corporation proceeds to issue the
9% bond on January 1, 2010. Since this 9% bond will be sold when the market interest rate is 8%, the
corporation will receive more than the bonds face value.
Lets assume that this 9% bond being issued in an 8% market will sell for $104,100 plus $0 accrued
interest. The corporations journal entry to record the issuance of the bond on January 1, 2010 will be:
Jan. 1, 2010 Cash 104,100
Bonds Payable 100,000
Premium on Bonds Payable 4,100
The account Premium on Bonds Payable is a liability account that will always appear on the balance
sheet with the account Bonds Payable. In other words, if the bonds are a long term liability, both Bonds
Payable and Premium on Bonds Payable will be reported on the balance sheet as long term liabilities.
The combination of these two accounts is known as the book value or carrying value of the bonds. On
January 1, 2010 the book value of this bond is $104,100 ($100,000 credit balance in Bonds Payable +$4,100 credit balance in Premium on Bonds Payable).
Premium on Bonds Payable with Straight-Line Amortization
Over the life of the bond, the balance in the account Premium on Bonds Payable must be reduced to $0.
In our example, the bond premium of $4,100 must be reduced to $0 during the bonds 5-year life. By
reducing the bond premium to $0, the bonds book value will be decreasing from $104,100 on January 1,
2010 to $100,000 when the bonds mature on December 31, 2014. Reducing the bond premium in a
logical and systematic manner is referred to asamortization.
The bond premium of $4,100 was received by the corporation because its interest payments to the
bondholders will be greater than the amount demanded by the market interest rates. Therefore, theamortization of the bond premium will involve the account Interest Expense. Each accounting period
during the life of the bond there needs to be a credit to Interest Expense and a debit to Premium on
Bonds Payable. In this section we will illustrate the straight-line methodof amortization. (In Part 10 we will
illustrate the effective interest rate method.)
Straight-Line Amortization of Bond Premium on AnnualFinancial Statements
If a corporation issues only annual financial statements and its accounting year ends on December 31,
the amortization of the bond premium can be recorded once each year. In the case of the 9% $100,000
bond issued for $104,100 and maturing in 5 years, the annual straight-line amortization of the bond
premium will be $820 ($4,100 divided by 5 years).
However, when a corporation issues only annual financial statements, the amortization of the bond
premium is often recorded at the time of its semiannual interest payments. Under this assumption the
journal entries on June 30 and December 31 will be:Jun 30, 2010 Interest Expense 4,090
Premium on Bonds Payable 410
Cash 4,500
Dec 31, 2010 Interest Expense 4,090
Premium on Bonds Payable 410

The combination of the interest payments and the bond amortization results in the net amount of $8,180
($4,500 of interest paid on June 30 + $4,500 of interest paid on December 31 minus $410 of amortization
on June 30 and minus $410 of amortization on December 31). This $8,180 will be reported in the account
Interest Expense for the year 2010 as shown in the following T-account:
Interest Expense
Jun 30, 2010 pmt minus amort 4,090
Dec 31, 2010 pmt minus amort 4,090
Dec 31, 2010 balance 8,180
The following T-account shows how the balance in the account Premium on Bonds Payable will decrease
over the 5-year life of the bonds under the straight-line method of amortization.

Straight-Line Amortization of Bond Premium on MonthlyFinancial Statements

Bond Discount with Straight-Line Amortization
When a corporation is preparing a bond to be issued/sold to investors, it may have to anticipate the
interest rate to appear on the face of the bond and in its legal contract. Lets assume that the corporation
prepares a $100,000 bond with an interest rate of 9%. Just prior to issuing the bond, a financial crisis
occurs and the market interest rate for this type of bond increases to 10%. If the corporation goes forward
and sells its 9% bond in the 10% market, it will receive less than $100,000. When a bond is sold for lessthan its face amount, it is said to have been sold at a discount. The discount is the difference between the
amount received (excluding accrued interest) and the bonds face amount. The difference is known by the
termsdiscount on bonds payable, bond discount, ordiscount.
To illustrate the discount on bonds payable, lets assume that in early December 2009 a corporation
prepares a 9% $100,000 bond dated January 1, 2010. The interest payments of $4,500 ($100,000 x 9% x
6/12) will be required on each June 30 and December 31 until the bond matures on December 31, 2014.
Next, let's assume that just prior to offering the bond to investors on January 1, the market interest rate
for this bond increases to 10%. The corporation decides to sell the 9% bond rather than changing the
bond documents to the market interest rate. Since the corporation is selling its 9% bond in a bond market
which is demanding 10%, the corporation will receive less than the bonds face amount.
To illustrate the accounting for bonds payable issued at a discount, lets assume that the 9% bond is sold
in the 10% market for $96,149 plus $0 accrued interest on January 1, 2010. The corporation's journal
entry to record the sale of the bond will be:
Jan. 1, 2010 Cash 96,149Discount on Bonds Payable 3,851
Bonds Payable 100,000
The account Discount on Bonds Payable (or Bond Discount or Unamortized Bond Discount) is a contra
liability account since it will have a debit balance. Discount on Bonds Payable will always appear on the
balance sheet with the account Bonds Payable. In other words, if the bond is a long term liability, both
Bonds Payable and Discount on Bonds Payable will be reported on the balance sheet as long term
liabilities. The combination or net of these two accounts is known as the book value or the carrying
valueof the bonds. On January 1, 2010 the book value of this bond is $96,149 (the $100,000 credit
balance in Bonds Payable minus the debit balance of $3,851 in Discount on Bonds Payable.)

Discount on Bonds Payable with Straight-Line Amortization
Over the life of the bond, the balance in the account Discount on Bonds Payable must be reduced to $0.
Reducing this account balance in a logical manner is known as amortizing oramortization. Since a
bond's discount is caused by the difference between a bond's stated interest rate and the market interest
rate, the journal entry for amortizing the discount will involve the account Interest Expense.
In our example, the bond discount of $3,851 results from the corporation receiving only $96,149 from
investors, but having to pay the investors $100,000 on the date that the bond matures. The discount of
$3,851 is treated as an additional interest expense over the life of the bonds. When the same amount ofbond discount is recorded each year, it is referred to as straight-line amortization. In this example, the
straight-line amortization would be $770.20 ($3,851 divided by the 5-year life of the bond).
Straight-Line Amortization of Bond Discount on Annual Financial Statements
If a corporation issues only annual financial statements on December 31, the amortization of bond
discount is often recorded at the time of its semiannual interest payments. In our example the journal
entries for 2010 under the straight-line method will be:
Jun 30, 2010 Interest Expense 4,885
Discount on Bonds Payable 385
Interest Payable 4,500
Dec 31, 2010 Interest Expense 4,885
Discount on Bonds Payable 385
Interest Payable 4,500
The interest expense for the year 2010 will be $9,770 (the two semiannual interest payments of $4,500
each plus the two semiannual amortizations of bond discount of $385 each). The following T-account for
Interest Expense shows the entries for the year 2010:

Calculating the Present Value of a 9% Bond in an 8% Market
The present value of a bond is calculated by discounting the bonds future cash payments by the
currentmarket interest rate.
In other words, the present value of a bond is the total of:
1. The present value of the semiannual interest payments,PLUS
2. The present value of the principal payment on the date the bond matures.
A 9% $100,000 bond dated January 1, 2010 and having interest payment dates of June 30 and
December 31 of each year for five years will have the following semiannual interest payments and the
one-time principal payment:
Interest: $4,500 $4,500 $4,500 $4,500 $4,500 $4,500
Principal: $100,000

0 Period No. 1 2 3 4 9 10
As the timeline indicates, the issuing corporation will pay its bondholders 10 identical interest payments of
$4,500 ($100,000 x 9% x 6/12 of a year) at the end of each of the 10 semiannual periods, plus a single
principal payment of $100,000 at the end of the 10th six-month period.
The present value (and the market value) of this bond depends on the market interest rate at the time ofthe calculation. The market interest rate is used to discount both the bonds future interest payments and
the principal payment occurring on the maturity date.
The present value of a bond =
1. The present value of a bonds interest payment,PLUS
2. The present value of a bonds maturity amount.
7/29/2019 Introduction to Bonds Payable F

Always use the market interest rate to discount the bonds interest payments and maturity amount to
theirpresent value.
1. Present Value of a Bonds Interest Payments
In our example, there will be interest payments of $4,500 occurring at the end of every six-month period
for a total of 10 six-month or semiannual periods. This series of identical interest payments occurring at
the end of equal time periods forms an ordinary annuity.
To calculate the present value of the semiannual interest payments of $4,500 each, you need to discount
the interest payments by the market interest rate for a six-month period. This can be done with computer
software, a financial calculator, or a present value of an ordinary annuity (PVOA) table.
We will use present value tables with factors rounded to three decimal places and will round some dollaramounts to the nearest dollar. After you understand the present value concepts and calculations, usecomputer software or a financial calculator to compute more precise present value amounts.
We will use the Present Value of an Ordinary Annuity (PVOA) Table for our calculations:
Click here to open our PVOA Table
Notice that the first column of the PVOA Table has the heading of n. This column represents the number
of identical payments and periods in the ordinary annuity. In computing the present value of a bonds
interest payments, n will be the number of semiannual interest periods or payments.
The remaining columns are headed by interest rates. These interest rates represent the market interest
ratefor the period of time represented by n. In the case of a bond, since n refers to the number
ofsemiannual interest periods, you select the column with the market interest rate per semiannual period.
For example, a 5-year bond paying interest semiannually will require you to go down the first column untilyou reach the row where n = 10. Since n = 10 semiannual periods, you need to go to the column which is
headed with themarket interest rate per semiannual period. If the market interest rate is 8% per year, you
would go to the column with the heading of 4% (8% annual rate divided by 2 six-month periods). Go down
the 4% column until you reach the row where n = 10. At the intersection of n = 10, and the interest rate of
4% you will find the appropriate PVOA factor of8.111.
The factors contained in the PVOA Table represent the present value of a series or stream of $1 amounts
occurring at the end of every period for n periods discounted by the market interest rate per period. We
will refer to the market interest rates at the top of each column as i.
To obtain the proper factor for discounting a bonds interest payments, use the column that has
the markets semiannual interest rate i in its heading.
Lets use the following formula to compute the present value of the interest payments onlyas of January
1, 2010 for the bond described above. The amount of the interest payment occurring at the end of each
six-month period is represented by PMT, the number of semiannual periods is represented by n and
the market interest rate per semiannual period is represented by i.
PVOA = PMT x PVOA factor

18/32
PVOA = $4,500 x PVOA factor for n=10 semiannual periods, i=4% market interest rate per semiannualperiodPVOA = $4,500 x 8.111PVOA = $36,500
The present value of $36,500 tells us that an investor requiring an 8% per year return compounded
semiannually would be willing to invest $36,500 on January 1, 2010 in return for 10 semiannual payments
of $4,500 eachwith the first payment occurring on June 30, 2010. The difference between the 10 future
payments of $4,500 each and the present value of $36,500 equals $8,500 ($45,000 minus $36,500). This$8,500 return on an investment of $36,500 gives the investor an 8% annual return compounded
semiannually.
Recap
Use the market interest rate when discountinga bonds semiannual interest payments. Convert the market interest rate per year to a semiannual market interest rate, i. Convert the number of years to be the number of semiannual periods, n. When using the present value tables, use the semiannual market interest rate (i) and the number
of semiannual periods (n).
Recall that this calculation determined the present value of the stream of interest payments. The present
value of the maturity amount will be calculated next.
2. Present Value of a Bonds Maturity Amount
The second component of a bond's present value is the present value of the principal payment occurring
on the bond's maturity date. The principal payment is also referred to as the bond's maturity value or face
value.
In our example, there will be a $100,000 principal payment on the bonds maturity date at the end of the
10th semiannual period. The single amount of $100,000 will need to be discounted to its present value as
of January 1, 2010.
To calculate the present value of the single maturity amount, you discount the $100,000 by the
semiannual market interest rate. We will use thePresent Value of 1 Table (PV of 1 Table) for our
calculations.
Notice that the first column of the PV of 1 Table has the heading of "n". This column represents the
number of identical periods that interest will be compounded. In the case of a bond, n is the numberof
semiannual interest periods or payments. In other words, the number of periods for discounting the
maturity amount is the same number of periods used for discounting the interest payments.
The remaining columns of the PV of 1 Table are headed by interest rates. The interest rate represents
themarket interest rate for the period of time represented by n. In the case of a bond, since n refers tothe number ofsemiannual interest periods, you select the column with the market interest rate per
semiannual period. For example, a 5-year bond paying interest semiannually will require you to go down
the first column until you reach the row where n = 10. Since n = 10 semiannual periods, you need to go to
the column which is headed with the market interest rate per semiannual period. If the market interest rate
is 8% per year, you would go to the column with the heading of 4% (8% annual rate divided by 2 six-
month periods). Go down the 4% column until you reach the row where n = 10. At the intersection of n =
10, and the interest rate of 4%, you will find the PV of 1 factor of0.676.

19/32
The factors contained in the PV of 1 Table represent the present value of a single payment of $1
occurring at the end of the period n discounted by the market interest rate per period, which will be
noted as i.
To obtain the proper factor for discounting a bonds maturity value, use the PV of 1 table and use the
same n and i that you used for discounting the semiannual interest payments.
Lets use the following formula to compute the present value of the maturity amount onlyof the bond
described above. The maturity amount, which occurs at the end of the 10th six-month period, is
represented by FV .
PV of 1 = FV x PV of 1 factorPV of 1 = $100,000 x PV of 1 factor for n=10 semiannual periods, i=4% market interest rate per
semiannual periodPV of 1 = $100,000 x 0.676PVOA = $67,600
The present value of $67,600 tells us that an investor requiring an 8% per year return compounded
semiannually would be willing to invest $67,600 in return for a single receipt of $100,000 at the end of 10
semiannual periods of time. The difference between the present value of $67,600 and the single future
principal payment of $100,000 is $32,400. This $32,400 return on an investment of $67,600 gives the
investor an 8% annual return compounded semiannually.
Recap:
When calculating the present value of the maturity amount...Use the semiannual market interest rate (i) and the number of semiannual periods (n) that were used to
calculate the present value of the interest payments.
Combining the Present Value of a Bonds Interest and Maturity Amounts
Recall that the present value of a bond consisted of:
1. The present value of a bonds interest payment,PLUS
2. The present value of a bond's maturity amount.
The present value of the bond in our example is $36,500 + $67,600 = $104,100.
The bonds total present value of $104,100 should approximate the bonds market value.
It is reasonable that a bond promising to pay 9% interest will sell for more than its face value when the
market is expecting to earn only 8% interest. In other words, the 9% bond will be paying $500 more
semiannually than the bond market is expecting ($4,500 vs. $4,000). If investors will be receiving an
additional $500 semiannually for 10 semiannual periods, they are willing to pay $4,100 more than the
bonds face amount of $100,000. The $4,100 more than the bond's face amount is referred to
as Premium on Bonds Payable, Bond Premium, Unamortized Bond Premium, or Premium.

The journal entry to record a $100,000 bond that was issued for $104,100 on January 1, 2010 is:

Bonds Payable 100,000
Premium on Bonds Payable 4,100
Amortizing Bond Premium with the Effective Interest Rate Method
When a bond is sold at a premium, the amount of the bond premium must be amortized to interest
expense over the life of the bond. In other words, the credit balance in the account Premium on Bonds
Payable must be moved to the account Interest Expense thereby reducing interest expense in each of the
accounting periods that the bond is outstanding.
The preferred method for amortizing the bond premium is the effective interest rate methodor
the effective interest method. Under the effective interest rate method the amount of interest expense in a
given year will correlate with the amount of the bonds book value. This means that when a bonds book
value decreases, the amount of interest expense will decrease. In short, the effective interest rate method
is more logical than the straight-line method of amortizing bond premium.
Before we demonstrate the effective interest rate method for amortizing the bond premium pertaining to a
5-year 9% $100,000 bond issued in an 8% market for $104,100 on January 1, 2010, let's outline a few
concepts:
1. The bond premium of $4,100 must be amortized to Interest Expense over the life of the bond.This amortization will cause the bonds book value to decrease from $104,100 on January 1,2010 to $100,000 just prior to the bond maturing on December 31, 2014.
2. The corporation must make an interest payment of $4,500 ($100,000 x 9% x 6/12) on each June30 and December 31. This means that the Cash account will be credited for $4,500 on eachinterest payment date.
3. The effective interest rate method uses the market interest rate at the time that the bond wasissued. In our example, the market interest rate on January 1, 2010 was 4% per semiannualperiod for 10 semiannual periods.
4. The effective interest rate is multiplied times the bonds book value at the start of the accountingperiod to arrive at each periods interest expense.
5. The difference between Item 2 and Item 4 is the amount of amortization.

Please make note of the following points:
Column B shows the interest payments required in the bond contract: The bonds stated rate of9% per year divided by two semiannual periods = 4.5% per semiannual period times the faceamount of the bond
Column C shows the interest expense. This calculation uses the market interest rate at the timethe bond was issued: The market rate of 8% per year divided by two semiannual periods = 4%semiannually.
The interest expense in column C is the product of the 4% market interest rate per semiannual
period times the book value of the bond at the start of the semiannual period. Notice how theinterest expense is decreasing with the decrease in the book value in column G. This correlationbetween the interest expense and the bonds book value makes the effective interest rate methodthe preferred method.
Because the present value factors that we used were rounded to three decimal places, ourcalculations are not as precise as the amounts determined by use of computer software, afinancial calculator, or factors with more decimal places. As a result, the amounts in year 2014required a small adjustment.
If the company issues only annual financial statements and its accounting year ends on December 31, the
amortization of the bond premium can be recorded at the interest payment dates by using the amounts
from the schedule above. In our example there was no accrued interest at the issue date of the bonds
and there is no accrued interest at the end of each accounting year because the bonds pay interest onJune 30 and December 31. The entries for 2010, including the entry to record the bond issuance, are:

Comparison of Amortization MethodsBelow is a comparison of the amount of interest expense reported under the effective interest rate method
and the straight-line method. Note that under the effective interest rate method the interest expense for
each year is decreasing as the book value of the bond decreases. Under the straight-line method the
interest expense remains at a constant annual amount even though the book value of the bond is
decreasing. The accounting profession prefers the effective interest rate method, but allows the straight-
line method when the amount of bond premium is not significant.

Notice that under both methods of amortization, the book value at the time the bonds were issued
($104,100) moves toward the bond's maturity value of $100,000. The reason is that the bond premium of
$4,100 is being amortized to interest expense over the life of the bond.
Also notice that under both methods the corporation's total interest expense over the life of the bond will
be $40,900 ($45,000 of interest payments minus the $4,100 of premium received from the purchasers of
the bond when it was issued.)

Calculating the Present Value of a 9% Bond in a 10% Market
Lets assume that a 9% $100,000 bond is prepared in December 2009. By the time the bond is offered to
investors on January 1, 2010 the market interest rate has increased to 10%. The date of the bond is
January 1, 2010 and it matures on December 31, 2014. The bond will pay interest of $4,500 (9% x
$100,000 x 6/12 of a year) on each June 30 and December 31.
To calculate the approximate price that an investor will pay for the corporations bond on January 1, 2010,
we need to calculate the bonds present value. The present value of the bond is the total of:
1. The present value of the bonds interest payments that will occur every six months,PLUS
2. The present value of the principal amount that occurs when the bond matures.
We calculate these two present values by discounting the future cash amounts by the market interest rate
per semiannual period.
1. Present Value of the Bond's Interest Payments
The first step in calculating the bond's present value is to calculate the present value of the bonds
interest payments. The interest payments form an ordinary annuity consisting of 10 payments of $4,500
occurring at the end of each six month period as shown in the following timeline:
Interest: $4,500 $4,500 $4,500 $4,500 $4,500 $4,500
.....
6 months 6 months 6 months 6 months 6 months01/01/10 06/30/10 12/31/10 06/30/11 12/31/11 6/30/14 12/31/14
0 Period No. 1 2 3 4 9 10
To obtain the present value of the interest payments you must discount them by the market interest rate
per semiannual period. In our example, the market interest rate is 5% per semiannual period. The 5%
market interest rate per semiannual period is symbolized by i. (The market rate of 10% per year was
divided by 2 semiannual periods per year to arrive at the market interest rate of 5% per semiannual
period.)
The bonds life of 5 years is multiplied by 2 to arrive at 10 semiannual periods. The number of semiannual
periods is symbolized by n.
Each semiannual interest payment of $4,500 ($100,000 x 9% x 6/12) occurring at the end of each of the
10 semiannual periods is represented by PMT.
We use the above amounts (i = 5%, n = 10, PMT = $4,500) in the following equation for calculating the
present value of the ordinary annuity (PVOA):
PVOA = PMT x [PVOA factor for n=10 semiannual periods, i=5% per semiannual period]
7/29/2019 Introduction to Bonds Payable F
25/32
PVOA = $4,500 x [7.722]PVOA = $34,749
(You will find more information about discounting an ordinary annuity at
AccountingCoach.coms Explanation of Present Value of an Ordinary Annuity.)
Recall that this calculation determines the present value of the stream of interest payments only. The
present value of the maturity amount will be calculated next.
2. Present Value of the Bonds Maturity Amount
The second step in calculating the present value of a bond is to calculate the present value of the maturity
amount of the bond as shown in the following timeline:
Principal: $100,000
.....
6 months 6 months 6 months 6 months 6 months01/01/10 06/30/10 12/31/10 06/30/11 12/31/11 6/30/14 12/31/14
0 Period No. 1 2 3 4 9 10
Since the corporations payment of the maturity amount occurs on a single date, we need to use the
factors from a Present Value of 1 Table (PV of 1 Table). When using the PV of 1 Table we use the same
number of periods and the same market interest rate that was used to discount the semiannual interest
payments. In this case we use n = 10 semiannual periods, i = 5% per semiannual period, and the future
value, FV = $100,000.
Using the PV of 1 table, we see that the present value factor forn = 10, and i = 5% is 0.614.
The calculation of the present value (PV) of the single maturity amount (FV) is:
PV = FV x [PV factor for n=10 semiannual periods, i=5% per semiannual period]PV = $100,000 x 0.614PV = $61,400
Combining the Present Value of a Bonds Interest and Maturity Amounts
Recall that the present value of a bond =
1. The present value of a bonds interest payment,PLUS
2. The present value of a bonds maturity amount.

26/32
The present value of the 9% 5-year bond that is sold in a 10% market is $96,149 consisting of:
1.$34,749 of present value for the interest payments,PLUS
2. $61,400 of present value for the maturity amount.
The bonds total present value of $96,149 is approximately the bonds market value and issue price.
It is reasonable that a bond promising to pay 9% interest will sell for less than its face value when the
market is expecting to earn 10% interest. In other words, the 9% $100,000 bond will be paying $500 less
semiannually than the bond market is expecting ($4,500 vs. $5,000). Since investors will be receiving
$500 less every six months than the market is requiring, the investors will not pay the full $100,000 of a
bond's face value. The $3,851 ($96,149 present value vs. $100,000 face value) is referred to
as Discount on Bonds Payable, Bond Discount, Unamortized Bond Discount, or Discount.

accrued interest is:Jan. 1, 2010 Cash 96,149

Amortizing Bond Discount with the Effective Interest Rate Method
When a bond is sold at a discount, the amount of the bond discount must be amortized to interest
expense over the life of the bond. Since the debit amount in the account Discount on Bonds Payable willbe moved to the account Interest Expense, the amortization will cause each periods interest expense to
be greater than the amount of interest paid during each of the years that the bond is outstanding.
The preferred method for amortizing the bond discount is the effective interest rate methodor
the effective interest method. Under the effective interest rate method the amount of interest expense in a
given accounting period will correlate with the amount of a bonds book value at the beginning of the
accounting period. This means that as a bonds book value increases, the amount of interest expense will
increase.
Before we demonstrate the effective interest rate method for a 5-year 9% $100,000 bond issued in a 10%market for $96,149, let's highlight a few points:
1. The bond discount of $3,851 must be amortized to Interest Expense over the life of the bond. Theamortization will cause the bonds book value to increase from $96,149 on January 1, 2010 to$100,000 just prior to the bond maturing on December 31, 2014.
2. The corporation must make an interest payment of $4,500 ($100,000 x 9% x 6/12) on each June30 and December 31 that the bonds are outstanding. The Cash account will be credited for$4,500 on each of these dates.
3. The effective interest rate is the market interest rate on the date that the bonds were issued. Inour example the market interest rate on January 1, 2010 was 5% per semiannual period for 10semiannual periods.
4. The effective interest rate is multiplied times the bonds book value at the start of the accounting
period to arrive at each periods interest expense.5. The difference between Item 2 and Item 4 is the amount of amortization.

Lets make a few points about the above table:
Column B shows the interest payments required by the bond contract: The bonds stated rate of9% per year divided by two semiannual periods = 4.5% per semiannual period multiplied timesthe face amount of the bond.
Column C shows the interest expense. This calculation uses the market interest rate at the timethe bonds were issued: The market rate of 10% per year divided by two semiannual periods = 5%semiannually.
The interest expense in column C is the product of the 5% market interest rate per semiannualperiod times the book value of the bond at the start of the semiannual period. Notice how theinterest expense is increasing with the increase in the book value in column G. This correlationbetween the interest expense and the bonds book value makes the effective interest rate methodthe preferred method for amortizing the discount on bonds payable.
Because the present value factors that we used were rounded to three decimal positions, ourcalculations are not as precise as the amounts determined by use of computer software, afinancial calculator, or factors that were carried out to more decimal places. As a result, ouramortization amount in 2014 required a slight adjustment.
If the company issues only annual financial statements and its accounting year ends on December 31, the
amortization of the bond discount can be recorded on the interest payment dates by using the amounts
from the schedule above. In our example, there is no accrued interest at the issue date of the bonds and
at the end of each accounting year because the bonds pay interest on June 30 and December 31. The
entries for 2010, including the entry to record the bond issuance, are shown next.

the amount of bond discount is not significant.

Notice that under both methods of amortization, the book value at the time the bonds were issued
($96,149) moves toward the bonds maturity value of $100,000. The reason is that the bond discount of
$3,851 is being reduced to $0 as the bond discount is amortized to interest expense.
Also notice that under both methods the total interest expense over the life of the bonds is $48,851
($45,000 of interest payments plus the $3,851 of bond discount.)

Additional Bond Terminology
Bonds are a form of long-term debt and might be referred to as a debt security.
Bonds allow corporations to use financial leverage or to trade on equity. The reason is that a corporation
issuing bonds can control larger amounts of assets without increasing its common stock.
Bonds that mature on a single maturity date are known as term bonds. Bonds that mature over a series of
dates are serial bonds.
Bonds that have specific assets pledged as collateral are secured bonds. An example of a secured bond
would be a mortgage bondthat has a lien on real estate.
Bonds that do not have specific collateral and instead rely on the corporations general financial position
are referred to as unsecured bonds ordebentures.
Convertible bonds allow the bondholder to exchange the bond for a specified number of shares of
common stock. Most bonds are notconvertible bonds.
Some bonds require the issuing corporation to deposit money into an account that is restricted for the
payment of the bonds maturity amount. The restricted account is Bond Sinking Fund and it is reported
in the long-term investment section of the balance sheet.
Callable bonds are bonds that give the issuing corporation the right to repurchase its bonds by paying the
bondholders the bonds face amount plus an additional amount known as the call premium. The call
premium might be one year of additional interest. A bonds call price and other conditions can be found in
a bonds contract known as the indenture.
Many years ago corporate bonds could be unregistered. Such bonds were known as bearer bonds and
the bonds had coupons attached that the bearer would clip and deposit at the bearers bank. Today,corporations do not issue bearer bonds. Instead, they issue registered bonds.
There are various fees that a corporation must pay when issuing bonds. These fees include payments to
attorneys, accounting firms, and securities consultants. These costs are referred to as issue costs. Issue
costs are likely to be recorded in the accountBond Issue Costs. This account appears on the balance
sheet under the heading of Other Assets or Deferred Charges. Over the life of the bonds the balance in
the long term asset account Bond Issue Costs will be amortized to expense.

When bond interest rates are discussed, the term basis pointis often used. A basis point is 1/100th of one
percentage point. For example, if a market interest rate increases from 6.25% to 6.50%, the rate is said to
have increased by 25 basis points.
