CORPFIN 2503 – Business Data Analytics

2021 S2, Group Assignment

Sigitas Karpavi£ius

Instructions

1. The assignment can be done in groups of one to three students. All team mem-

bers are expected to contribute approximately equally to a group assignment.

A group can eliminate an underperforming member who then will need to do

the assignment individually or join another group. Similarly, one can quit

an underperforming group to do the assignment individually or join another

group. All group members will get the same mark for the assignment.

2. The maximum score is 30 points.

3. The presentation of your write-up is important. Up to 5 bonus points will

be given for a properly formatted report.

4. All numerical analysis, all tables and �gures need to be done using SAS (how-

ever, you may use Excel or Word etc. to make tables for regressions as the

standard SAS output for regressions is not very nice).

5. Please retain your SAS code and make sure that it is user-friendly (use com-

ments where necessary). Using your submitted code and data set, one should

be able to produce all your results, tables, and �gures.

6. Please retain a copy of the problem set that is submitted.

7. Only one member of a group submits:

� a SAS code,

� a data �le (e.g., in txt, csv, xls, xslx formats), and

1

� the report (in doc, docx, or pdf format) with `Group Assignment Cover

Sheet’, which must be signed (electronic signature is okay) and dated

by all group members before submission; the report should be properly

formatted and be similar to a business report; font: 12 pt Times New

Roman; maximum number of pages: 15.

8. Lecturer can refuse to accept assignments, which do not have a signed ac-

knowledgment of the University’s policy on plagiarism.

9. Any suspected plagiarism will be severely punished. This includes any student

that submits copied work or any student that allows their work to be copied.

10. You must acknowledge any external material you use in your answers, e.g.,

material from websites, textbooks, academic journals and newspaper articles.

11. All queries (including deadline extensions) for this project should be directed

to Lecturer.

12. The submission deadline for the problem set is 6pm, Monday the 18th of

October, 2021.

13. The submission must be done through MyUni.

14. Late submission will be penalized 3 points per day.

Agenda

The assignment is based to some extent on Workshop 4. Assume that you are a

bond analyst and you have been asked to focus on the U.S. corporate bond market.

1 Sample and description statistics (5 points)

From Eikon download bond issues with the following characteristics:

1. Sector: Consumer Goods, Manufacturing, Service Company, Telephone, Trans-

portation

2. Domicile: United States

2

3. Amount Outstanding: ⩾ 100,000,000

4. Coupon: > 0%

5. Maturity: ⩾ 1-October-2026

6. Moody’s (Issue) Credit Rating: ⩾ C

7. Putable: No

8. Market of Issue: Domestic, Global, or Eurobond

9. make sure that the following �lters are visible on the left hand side:

(a) Currency

(b) Convertible

(c) Callable

(d) Seniority.

You should end up with more than 4,000 bonds; thus, you will need to download

the data to Excel in batches (e.g., �rst, download small bond issues, then medium,

and lastly with large bond issues). From the remaining issues, drop the convertible

bonds.

Discuss brie�y your sample, including the number of observations, outliers. Pro-

vide the descriptive statistics of the sample. How you choose to do this is entirely at

your discretion. However, it is recommended that you consider using both summary

statistic and graphical methods (this task should include at least one properly for-

matted table, one pie chart, one histogram, and one scatter plot) while also noting

any peculiarities within the data set. You should put more emphasis on variables

that are the dependent variables in the regressions estimated in other tasks.

2 Which bonds are more likely to include �a call�

feature? (7 points)

A bond issuer can repurchase its bonds before their maturity if they include a call

feature. Firstly, identify statistically signi�cant characteristics of callable bonds.

3

You may consider, issue size, maturity, industry, credit rating, and other variables

available in Eikon. Secondly, compute the average of the individual marginal e�ects

of the amount outstanding on the probability that a bond includes a call feature.

Thirdly, estimate the probability that a bond with the following characteristics

includes a call feature:

� maturity: 10 years

� coupon: 2.5%

� amount: $750,000,000

� currency: US dollars

� seniority: senior unsecured

� Moody’s (Issue) credit rating: Aa2

� sector: Electronics

� domicile: USA

� convertible: no

� market of issue: global

� puttable: no.

Do the results suggest that this bond is callable or not?

In this task, you are expected to use a logit regression analysis. To ensure that

the results are robust, estimate at least two regression models (e.g., in the �rst

regression model, one includes amount in $ and in the second model, one uses the

natural logarithm of amount in $).

3 Which bonds are more likely to be issued in the

domestic and foreign markets? (6 points)

�Market of Issue� can take the following values:

� Domestic: a bond is issued in the US

4

� Global: a bond is issued in the US and foreign markets

� Eurobond: a bond denominated in USD is issued in the foreign market.

You need to estimate the probabilities that a bond with the following character-

istics is issued in each market:

� maturity: 10 years

� coupon: 2.5%

� amount: $750,000,000

� currency: US dollars

� seniority: senior unsecured

� Moody’s (Issue) credit rating: Aa2

� sector: Electronics

� domicile: USA

� convertible: no

� callable: yes

� puttable: no.

In the analysis, estimate multinomial logit regression model and brie�y discuss the

determinants of �Market of Issue.� According to the analysis, what is the most likely

market of issue of this bond?

4 Estimating yield for a hypothetical bond (7 points)

Lastly, you need to estimate the yield for a bond with the following characteristics:

� maturity: 10 years

� coupon: 2.5%

� amount: $750,000,000

5

� currency: US dollars

� seniority: senior unsecured

� Moody’s (Issue) credit rating: Aa2

� sector: Electronics

� domicile: USA

� convertible: no

� callable: yes

� puttable: no

� market of issue: global.

To ensure that the results are robust, estimate at least 3 regression models (e.g.,

in the �rst regression model, one includes amount in $, in the second model, one

uses the natural logarithm of amount in $, and the third model features something

else). Brie�y discuss the determinants of yield.

Using one of the regression models, compute two additional yields:

1. the amount is $1,000,000,000, other bond characteristics the same as above

2. Moody’s (Issue) credit rating is A2, other bond characteristics the same as

above (i.e., amount: $750,000,000 etc.).

Are the results the same as the main estimate? Why?

Additional information

1. Before implementing statistical and regression analysis, check whether your

sample includes any outliers and duplicate observations. If needed, take nec-

essary actions to deal with them.

2. To ensure that regression residuals �behave well,� you may need to scale or

transform one or more variables. For example, to use a natural logarithm

value of the variable instead of its raw value.

3. In the analysis, you should only use the data that can be downloaded from

Eikon.

4. You may move technical calculations to Appendix if you think it helps your

report to look more professional.

Good luck!
