Abstract
Using financial statements of over 600 enterprises listed on Ho Chi Minh City Stock
Exchange and Hanoi Stock Exchange provided by Stockplus Financial Media Corporation
from 2005 to 2010, this study apply Multiple Discriminant Analysis (MDA) to predict default
for Vietnamese listed enterprises.
This study aim to examine the validity that financial ratios can be used to predict default for
Vietnamese listed enterprises. The ratio “Total debts / Total assets” has positive relationship
with default while other ratios such as “Current assets / Total assets”, “Accounts Receivable /
Earnings before interest and tax ” and “Earning before taxes / Total assets” have negative
relationship with default.
The results of this thesis are consistent with economic theories and previous studies about
financial ratios analysis and default prediction.
Keywords: Default, Multiple Discriminant Analysis, MDA, Z-score; Vietnam Stock
Markets, financial ratios.

Chapter 1: Introduction
1.1 Background and Relevance of the Thesis
Vietnam's economy is in the conversion mechanism operating under market-oriented socialist
and gradual industrialization - modernization. In the market mechanism of economic relations
took place mixed under the influence of market forces in the economic rules. In the market
economy, government, banks and enterprises always need an objective assessment of the
operations, prospects for future growth, the credit status to investment decisions, mergers and
acquisitions, credit financing, co-operation, or supply goods.
In the process of production and business operations, businesses often face with the risks and
potentially lead to default. Multiple Discriminant Analysis points out the limitations and
factors affecting the ability of business default.
On the other hand, in the banking business, banks face credit risk is unavoidable. The problem
is how to limit risks for banks at the acceptable rate.
Thus, in this study, we want to apply Multiple Discriminant Analysis to identify default for
Vietnamese listed enterprises. The results of this research are the basis for proposals to reduce
default of enterprises and help banks to give the right credit decisions for these enterprises.
The paper makes several contributions to the default prediction and financial analysis.
1.2 Scope, limitations and Research Questions
This study is only focus on evaluating default for Vietnamese listed enterprises from 2005 to
2010. Enterprises belonging in the financial sector (banks, investment enterprises) were
excluded.
We identified default for Vietnamese listed enterprises using MDA model to answer the
question: Which factors determine default for Vietnamese listed enterprises? Moreover,
some sub questions are also focused on in this thesis as follow:
Sub – questions:
1. How to classify enterprises depend on high risk or less risk?
2. Which sectors are more risky?
3. How the scale of the business affect to risk?
1.3 Structure of the Thesis
This thesis includes five chapters:
2
Chapter I: Introduction. In this chapter, we introduce the topic of thesis work with
background, relevance, scope, limitations and research questions.
Chapter II: Literature review and current situation of Vietnam stock market from 2005
to 2010. In this chapter, we briefly summarize some popular methods to estimate default with
their advantages and disadvantages. We also review some literatures about Multiple
Discriminant Analysis with focusing on Vietnam and summarize situation of Vietnam stock
market form 2005 to 2010 with some main points.
Chapter III: Data and Methodology. In this chapter, we introduce our method to estimate
default for Vietnamese listed enterprises and Data collection.
Chapter IV: Estimation results. We estimate result and specify the regression model with
independent variables that is considered as the determinants of Multiple Discriminant
Analysis.
Chapter V: Summary, limitations and suggestions for further research. In this chapter, we
summarize the main findings in previous chapters. We also analyse the limitations of this
study and recommend some idea for further research.

Chapter 2: Literature review and current situation of
Vietnam stock market from 2005 to 2010
2.1 Literature review
Detect problems in the operations of enterprises based on financial ratios is a particularly
vulnerable topic. Before developing the quantitative measure of enterprises’ performance,
many organizations have been established to provide the type of information to evaluate the
reliability of the repayment capacity of merchants. For example, Dun & Bradstreet
Corporation1 provided independent information on businesses and corporations for credit
decisions.
In 1930, studies of forecasting business failures began to appear. In studies focused on
forecasting the possibility of default and bankruptcy, there are some significant post relatively
important contributions. Ramser and Foster (1931), Fitzpatrick (1932), Winakor and Smith
(1935), and Mervin identified problems associated with the value of financial ratios of
bankruptcy and non-bankruptcy companies are different. These studies have established the
foundation for studies of bankruptcy prediction later.
A change in traditional research occurs when the Beaver (1966) has introduced a univariate
analysis. Through separate test of every financial ratio calculated from financial statements of
79 bankrupt enterprises and 79 non-bankrupt enterprises, he found that the ratio “cash flows /
total debts” is the best variable for bankruptcy prediction in all ratios was examined. The
results of his research show that the rate of error prediction for one year before the bankruptcy
event is 13% and for two year before the bankruptcy event is only 9%.
Soon after, Altman (1968) was pioneer used multivariate approach in bankruptcy prediction.
He developed a basis model of discrimination. Discrimination analysis found a linear function
of variables and financial markets that can best distinguish between the two layers of
enterprise: non-bankruptcy and bankruptcy. Similarly, the logit analysis using financial
variables to predict probability of bankruptcy with an assumption that probability of
bankruptcy is Logistic distribution, this function is known as logistic function. Therefore, its
value is in the range (0, 1). Altman using model discrimination analysis, based on data of
bankrupt firms from 1946-1965 in the U.S. and obtained discrimination function (Z) as
follows:
Z = 1.2 X1 + 1.4 X2 + 3.3 X3 + 0.6 X4 + 1.0 X5
Where: X1,…,X5 are defined as bellow:
1 Dun & Bradstreet (NYSE:DNB) – a US company established in 1849 in Cincinnati, Ohio
4
Variables Symbol
working capital / Total assets; X1
Retained earnings / Total assets;
X2
Earnings before interest and tax (EBIT) / Total assets; X3
Market value of equity / Book value of total liabilities; X4
Sales / Total assets X5
• If Z > 2.99: The enterprise is located in the safety zone, there is no risk of bankruptcy;
• If 1.81 < Z <2.99: The enterprise is located in the alert zone, there may be at risk of
bankruptcy;
• If Z < 1.81: The enterprise is located in the danger zone, a high risk of bankruptcy.
Discrimination function Z can be used for most industries and most types of businesses.
However, because of significant differences between sectors of the variables X5, the X5 was
launched from the Altman model and proposed model the following adjustments:
Z’ = 6.56X1 + 3.26X2 + 6.72X3 +1.05X4
• If Z' > 2.6 The enterprise is located in the safety zone, not risk bankruptcy;
• If 1.2 < Z'< 2.6 The enterprise is located in the alert zone, there may be at risk of
bankruptcy;
• If Z' < 1.2 The enterprise is located in the danger zone, high risk of bankruptcy.
Based on 700 research firms rated by S&P, Altman found similarities between the Z' and
credit rating by S&P, and he offers Z'' with the following function:
Z’’ = 3,25 + 6,56X1 + 3,26X2 + 6,72X3 + 1,05X4
According to Altman, the degree of similarity is quite high, but by no means absolute.
Altman (1997) has used discrimination analysis model with seven variables (including X1:
ratio of earnings before interest and tax / total assets; X2: coefficient Retained Earnings /
Total assets; X3: Ratio of Equity / Total capital; X4: current ratio; X5: Standard deviation of
X1 between 5 - 10 years; X6: Ratio of Earnings before interest and tax / Interest payments;
X7: Total assets). Many own versions of the model were launched. In general, the model
includes seven variables is often called the "Zeta". These models are considered as extension
of the model includes five variables of Altman (1968).
5
Scott (1981) has used these variables in their experimental model. He concluded that the Zeta
models are in close relationship with his theory of bankruptcy due to construction.
Similarly, Ling Zhang, Shou Chen and Jerome Yen applied MDA models use 32 financial
ratios of 164 enterprises in China and obtained the following results:
Z=-8.751+6.3X1+0.761X6+1.29X21+0.41X23+0.015X24+0.105X31 -21.164X32
Of which: X1: Net income / total assets; X6: Cash flow from operations / Total number of
treasury shares; X21: Ln(fixed assets); X23: Growth from business activities; X24: Retained
earnings / Net income; X31: Market value of equity / Total liabilities; X32: Book value of
equity / Market value of equity.
• If Z > 0.71: The enterprise is located in the safety zone, without risk of bankruptcy;
• If -0.5 < Z <0.71: The enterprise is located in the alert zone, could risk bankruptcy;
• If Z < 0.71: The enterprise is located in the danger zone, high risk of bankruptcy.
Model in China has obtained an independent variable in the function of distinguishing more
and different models of Altman found in the U.S., this difference might be due to differences
in the characteristics of the economy in two countries.
Martin (1977) use logit model and discrimination analysis to predict bankruptcy of banks in
the 1975-1976 periods. Meanwhile, there were 25 banks were insolvent; both models gave
results consistent with real class.
Ohlson (1980) calculated financial ratios from 105 bankrupt enterprises and 2.058 non-
bankrupt enterprises from 1970 to 1976. He used logit model with nine independent variables
to predict bankruptcy. He obtained overall O-Score function as bellow:
O-Score = -1.32 – 0.407 log(MKT ASSET/CPI) + 6.03TLTA – 1.43WCta + 0.076Clca –
1.72OENEG – 2.37NITA – 1.83FUTL + 0.285INTWO– 0.521CHIN
Of which: MKT ASSET = Total liabilities + market equity; CPI: consumer price index;
TLTA = Book value of debt / MKT ASSET; WCTA = working capital / MKT ASSET;
CLCA = current liability / current assets; OENEG = 1 if total liabilities > total assets, else =0;
NITA = net income / MKT ASSET; FUTL = fund provided by operations / liability; INTWO
= 1 if net income <0 for the last two years, else = 0; Chin = (Net incomet – Net incomet-
1)/(|Net incomet – Net incomet-1|). Results of his research indicate that these factors can
predict bankruptcy for one and / or two years before bankruptcy and accuracy of bankruptcy
prediction is better in one year before bankruptcy.
West (1985) used the logit model combined with factors analysis to measure the financial
conditions of financial institutions and give the probability of bank insolvency. Specifically,
factors used in this model similar to Camel model used for ranking banks. Platt (1991) used
6
the logit model of the testing and selecting financial variables and found that using sector’s
financial variables are better than financial variables of a single enterprise for predicting
bankruptcy of enterprises. Smith and Lawrence (1995) used logit model to select the best
variable to predict insolvency of the country. They said that debt data used in the past is
important in forecasting default.
Casey and Bartczak (1985) use financial data of 60 bankrupt and 230 non-bankrupt
enterprises in the period of five years before bankruptcy with variables related to cash flow
(Operational cash flows / Total debts, Operational cash flows / Current debts) and financial
ratios (Net benefit of the working capital / Total assets, Net benefit / Total assets, Debts /
Total assets …) to predict bankruptcy. The results of his research suggest that variables
related to cash flow have more power in predicting bankruptcy than financial ratios.
Gahlon and Vigeland (1988) compare the ratios related to cash flows (The operational cash
flows resulting from sale) to the financial ratios (cash coverage ratio, current assets / current
debts, EBIT / total assets...) for 60 bankrupt and 204 non-bankrupt enterprises in a period of
five year before bankruptcy and found that ratios related to cash flows and financial ratios are
all useful to predict the bankruptcy.
Gilbert et al. (1990) used financial data of 52 bankrupt and 208 non-bankrupt enterprises with
variables (Operational cash flows / current debts, operational cash flows / total debts, cash
flows / total debts, EBIT / total assets, sale / total assets ,…) to predict bankruptcy. Using
stepwise method, his study show that financial ratios from accounting data is significance for
bankruptcy prediction and variables form cash flows also useful.
Research by Robbins and Pearce (1992) show that Z-score is not only used to predict the risk
of bankruptcy but also can be used as a benchmark to measure changes in the business
recovery process. Research shows that Z-score of enterprises can be improved following a
restructure process more than 12 months through improving financial ratios.
Also use discriminant analysis method, Gardiner (1996) has accurately predicted hospital
failed. His research find out a discriminant function combine of financial variables and non-
financial variables to predict bankruptcy for all public hospitals and private hospitals.
Through data analysis of financial statements published by the Greek business using
traditional Z-scores added nine ratios, which are all included in a logistic regression model,
Spathis (2002) have found that the potential causes of bankruptcy is a financial fraud such as
inflated profits, overstated revenues, understated expenses and overstated assets. However, he
did not provide a specific level of impact.
In Japan, Cindy Yoshiko Shirata (1998) collected financial data of 686 bankrupt and 300 non-
bankrupt Japanese enterprises from Teikoku Data Bank’s Cosmos1Data Base from 1986 to
1996. He obtained a linear MDA model as bellow:
7
Z= 0.7416 + 0.014X2 –0.003X10 – 0.058X24 – 0.062X36
Of which: X2: Retained earnings / total assets; X10: Current gross capital / Previous gross
capital -1; X24: Interest and discount expense / Borrowings + corporate bond + note
receivable discounted; X36: (Note payable + accounts payable) / Sale.
• If Z > 0.38: The enterprise is located in the safety zone, without risk of bankruptcy;
• If Z < 0.38: The enterprise is located in the danger zone, high risk of bankruptcy (86,14%
probability go bankrupt).
Besides, the research also found that industry and scale is not affect to bankruptcy probability
and this model is better in predicting bankruptcy for Japanese enterprises.
In India, Arindam Bandyopadhyay (2006) collected financial data of 104 listed enterprises
from Credit Rating and Information Services of India Ltd. (CRISIL), used multiple
discriminant analysis to develop a discriminant function (Z-Score) for Indian enterprises
apply in predicting bond default. The results of his study showed that the discriminant model
can highly detect bad enterprises and can early predict bankruptcy for enterprises with an
accuracy rate of 97% (for one year) and 96.3% (for two year). This model can help the banks
and investors to identify high-risk bonds in the bond investment activities.
In Iran, using financial data of companies listed on Tehran Stock Exchange (TES) from 1995
to 2007, the regression model of Mahdi Salehi, Bizhan Abedini (2009) used 22 primary
financial ratios of 60 enterprises (30 enterprises faced financial distress and 30 enterprises do
not have any financial distress) indicated that the accounting data have a high-strength
predictions in predicting the financial distress, which may lead to bankruptcy. By predicting
financial distress, enterprises can adopt necessary policies to strengthen financial ratios to
avoid financial distress and bankruptcy.
In Ghana, Bright Kpodoh (2009) used financial data of mobile telecommunication industry
from National Communication Authority - Ghana to test Altman’s Z-score prediction model.
His research confirmed that Z-score model have a high ability in predicting businesses failure
for telecommunication enterprises.
In the United Kingdom, Khorasgani, Amir (2011) used more than 30.000 SMEs in the period
2000-2008 in 22 United Kingdom manufacturing industries to find suitable predictive model
for enterprise’s default. This study examines default predicting models of both Altman and
Ohlson and found that Altman’s model is more efficiency compare to Ohlson’s model. The
results of his research also found that default prediction for SMEs differences across
industries and segments (private and public). This study found that corporate governance and
controlling market share have significantly effect to default prediction models and it is useful
for banks and SMEs in making financing decision.
8
In Vietnam, Lam Minh Chanh (2009) used Z-Score model of E.I. Altman to detect the risk of
bankruptcy and ranked credit ratings base on Z-score in Vietnam. He has also given some
methods to increase Z-score by affect each X-indicator in the model. He also found a high
similarity between adjusted Z-score (Z'') and S&P’s credit rating, through which, the author
assessed the reliability of Z'' and can rely on Z'' to rank credit rating. These results help
enterprises and investors can easily identify the basic financial situation and solvency of the
company's debt.
Nguyen Thanh Cuong, Pham The Anh (2010) have applied the model of E.I.Altman Z scores
to assess the risk of bankruptcy of enterprises processing aquatic products are listed on the
stock market in Vietnam. Based on research results, the authors found Z targets depends
primarily on total assets and make recommendations to help businesses increase Z score to
reduce the risk of bankruptcy, such as management and use effectiveness of the business
assets, financial restructuring towards increasing equity and improving the efficiency of
production and business activities. Research results also help banks with the right decision
before granting credit to the fishery enterprises, thus contributing to improve the effectiveness
of risk management in banking activities.
In recent years, there have been many different methods without using the model parameters
in the development process. Including classification tree models and neural networks. Altman,
Marco & Varetto (1994) and Yang (1999) used neural network models and analysis results
better than the classic layer model.
Through summarizing the results of previous studies showed that there were many methods or
models have been proposed, applied and obtained good results in practice. However,
statistical models have been used by most experts because the models based on proven
scientific principles with highly accuracy and efficiency when applied while the neural
network model with more complex functions require powerful soft-wares with missing in
Vietnam. These are important lessons and a prerequisite for me to use the MDA approach in
this thesis.
2.2 Financial situation of listed enterprises from 2005 to 2010
Vietnam stock market was formed in 2000 with transactions not very exciting until 2005. In
2005, stock market trading was exciting and the real evolution of the market is always
associated with Vietnam’s economic fluctuations. The market trading value of Vietnam stock
market growth up 64% over 2004, the largest growth since its formation. Market value of
listed securities increased 1.6 times, equivalent to 6.5% of GDP in 2005. In 2005 also marked
the launch of Hanoi Securities Trading Center (HASTC) on 08/03/2005, more active
supported for the equalization process, created the binding between the equalization and stock
9
markets, facilitated the expanding stock markets with high organization, protected investors
and increased the accessibility of public, enterprises to the stock markets. Overall in 2005,
though always active in terms of price volatility in raw materials and natural disasters affected
the disease, but with effort and predict the difficult situation in 2005, Listed enterprises have
obtained business results relatively optimistic. Many enterprises have growth in revenue and
profit than in 2004, in which SAM (SACOM Cables and Telecom Materials) is most
impressive: increased revenue and profit rose 72.13% and 41.19%; DHA (Hoa An Stones and
Materials): increased revenue 35.09% and 63.73% profit increase; NKD (North Kinh Do
Food): revenue increased 28.99% and 49.28% profit increase. Regarding the financial
situation, enterprises wishing to raise capital to finance its projects by issuing additional
shares, most listed companies are not much changed in financial position compared to 2004,
the ratio at a safe level, and the debt on the property without many changes compared to 2004.
The indicators on the profitability of listed companies will have no more changes than in
2004.
Stage 2006 - 2007 marked a period of booming stock market. In 2006, trading activity of
Vietnam stock markets was very exciting, growth up to 60% from early to mid-2006.
Vietnam's stock market stock market became No. 2 rapid growth of the worlds, just after the
Zimbabwe’s stock market. The strong growth of Vietnam's stock market has attracted capital
flows from domestic and foreign investors. The VN-Index (the total index of Ho Chi Minh
Stock Exchange - HoSE) increased 144% in 2006 and HASTC-Index (the total index of
Hanoi Securities Trading Center – HASTC) increased 152.4%. Total capitalized value
reached 13.8 billion at the end of 2006 (22.7% GDP). Foreign investors held approximately 4
billion USD stock values, accounting for 16.4% of the total market capitalization. Market
capitalization in 2006 has increased by 15 times the previous year; this is a very impressive
figure. Number of listed enterprises increased nearly five times from 41 enterprises in 2005
amounted to 193 enterprises, trading account number over 10 thousand, increasing three times
the previous year and 30 times over six years ago. Within a year, only the VN-Index up more
than 500 points, from more than 300 at the end of 2005 to 800 at the end of 2006.
Securities Law effective from 01.01.2007 has contributed to promoting market development
and enhanced integration into international financial markets. Openness and transparency of
the listed enterprises are strengthened. VN-Index peak at 1170.67 points and HASTC-Index
hit 459.36 points milestone. Overall evolution of the market and stock prices in transactions is
more volatile, Indexes of the two exchanges have strong fluctuation. At the end of 2007, VN-
Index downed to 927.02 points and HASTC-Index downed to 323.55 points. Therefore, after
a year, VN-Index achieved growth of 23.3%, HASTC-Index 33.2% from set point at the end
of 2006. In 2007, Ho Chi Minh Stock Exchange (HoSE) made 248 day of transactions with
total transaction volume of over 2.3 billion of securities equal to the total transaction value of
10
the market reached 224,000 billion VND with volume increase 2 times and value increase 2.8
times compared to 2006. Hanoi Securities Trading Centre (HASTC) also made 248 successful
day of transactions, with total trading volume reached 616.3 million securities equivalent to
the total transaction value of the market reached 63,859 billion with volume increase 6 times
and value increase 15.8 times compared to 2006.
Period 2006-2007 is the most successful stage of listed enterprises, particularly financial
sector. Profit of listed enterprises exceeded high. One of the sources provides superior
business results from activities such as investment securities. From financial statements of 50
enterprises with the largest profit on each trading floor in 2006 - 2007, there were more than
90% of enterprises with revenues from financial investments. Of these, over 50% of
enterprises with financial revenues accounted for more than 10% of profit after tax.
2006 - 2007 is also a stage that listed companies issue stocks to increase equity dramatically.
The issuing took place in almost all listed companies to increase capital ratios averaged about
17% / year. Although stocks are diluted by the issuance, revenue growth, profit growth and
profit margin in this period is still very satisfactory. Average growth rate of revenue growth
and profits are over in this period are 56% and 26.2%. Enterprises in the banking sector (STB
– Sacombank and ACB – Asia commercial bank) and securities (SSI – Saigon Securities Inc.
and BVS – Baoviet securities) growth with revenue growth respectively of 96.3%, 118.24%,
202.1% and 247%. Some enterprises tend to diversify participation in the business of real
estate and finance; two of the industries are growing and most profitable of the Vietnam
economy in this period. FPT Group (FPT) has obtained permission to set up securities firm
and invest in a new establishment bank; Refrigeration Electrical Engineering (REE) expanded
into real estate and finance; Kinh Do confectioneries (KDC) buy 6.42% shares in Eximbank
and start real estate investment in Ho Chi Minh.
In the 2008 period, with the general downtrend of the economy, Vietnam's stock market
closed in 2008 with the sharp decline. Looking back on the market after 01 years of trading,
the highlights of the market was: Indexes decline, price of stocks fell sharply (several stocks
fell below par value), less liquidity, the degradation of foreign capital, the intervention of the
government and gloom in the psychology of investors.
In this period, commodity price increases in all goods from necessities, building materials ...
to the essential commodities of the country such as gasoline, electricity ... Lack of capital
leads to pressure the mortgage operations and mortgage securities, interest rate increases and
limited lending capacity of banks affect the production and business activities of listed
enterprises, especially enterprises in financial and real estate sectors. Most enterprises have
profits decline significantly in 2007, of which, many companies have huge losses from
financial investments, in which, Refrigeration Electrical Engineering (REE) with 100 billion
loss because of provisioning by financial investment in the quarter I/2008 and continues to be
11
127 billion after five months in 2008. In this year, many listed enterprises fall into losses with
over 40 companies reported losses.
In 2009, Vietnam's stock market continues to decline. The VN-Index from the beginning of
the year down 22%, the worst lower than other Asian markets. Value of shares traded per day
in February / 2009 in Ho Chi Minh City Stock Exchange and the Securities Exchange Hanoi
is 13 million. The total market value falls to $ 10 billion. Profit of listed enterprises in 2009 is
not very positive. Sales growth of 40% over the same period last year but operating profits
rose 8%. Losses in real estate investments and securities pushed net profit down 25%. Of the
329 listed enterprises, 23 enterprises lost.
Vietnam's stock market in 2010 suffered from the impact of macroeconomic factors of world
economy and domestic economy. Some of the direct causes little to no impact on the stock
market in 2010, namely the continuation of the economic stimulus package in 2009 to the end
of first quarter 2010, the fever "bubble" real estate market production in first quarter 2010,
gold prices rose to record highs as the cause of a strong impact on the evolution of the stock
market in 2010.
Through the monitoring of changes in the stock market in 2010, can be assessed in common:
the stock market in 2010 but showed signs of better than the situation in 2009, reflecting the
recovery of the Vietnamese economy from the impact of world financial crisis, but growth is
steady, continuously fluctuated in a narrow margin to more trading with very low value. By
the end of 2010, the two stock exchanges (HoSE & HASTC) have 647 listed enterprises, up to
42%, or 192 newly listed enterprises, a highest annual growth in 10 years. Total market
capitalization of reach 717.2 trillion (equivalent to about 36% of GDP). In terms of absolute
value, the capitalization of this year nearly 100 trillion VND, higher than in 2009 (in 2009,
stock market capitalization reached 620.5 trillion). With the growth of new listed enterprises,
the number of investor accounts opened at securities enterprises has increased sharply and
reached over 1 million accounts by the end of 2010, up 33.5% compared to investor's
accounts at the end of 2009. There were 105 securities enterprises, 47 fund management
enterprises, 382 foreign investment funds. By the end of 2010 there were more than 1,400
accounts of organizations and more than 13,000 individual accounts of foreign investors in
Vietnam's stock market opened. General Results from the Ho Chi Minh Stock Exchange and
Hanoi Stock Exchange Centre that, from the beginning of the year, foreign investors have
maintained the trend of net buying on the Vietnam’s stock. Total net buying was estimated at
nearly 20,000 billion - about $ 1 billion (more than 5 times the figure in 2009 - in 2009, net
buying by foreigners only reached 3,500 billion). This is the only net buyers ranked second
after the record of more than 24,000 billion in 2007.

Chapter 3: Data and Methodology
When using a complete list of financial ratios to assess the potential default of an enterprise, it
is truly that some measure will be the collinear or highly correlated with other metrics. While
this aspect requires careful selection of variables (the ratio), it can find a model with a few
measurements have the potential to be selected in large part information. This information
may indicate very clearly the difference between the groups, but the difference this makes
sense or not is an important aspect of this analysis. It is truly that there are differences
between default enterprises and non-default enterprises, but these differences can be critical to
be able to build a predictive model correct?
The main advantage of multiple discriminant analysis (MDA) is that research objects are
classified by analysis of the entire set of variables of the object at a time rather than turn to
consider its own specific characteristics. MDA approach for ratio analysis techniques has
traditionally shown the potential for this problem correctly. In particular, the combination of
scores can be analyzed together to eliminate confusion and misclassification may be that we
found in previous studies.
Based on the qualities described above, we choose MDA to study the default of Vietnamese
listed enterprises.
3.1 Default definition
Businesses can fall into default as an objective economic phenomenon in the market economy
that it is the result of conflicts of interest of all stakeholders involved in economic relations. It
is not only a conflict between the interests of debtors unable to pay its creditors, but also led
to conflict with the collective interests of the employees working in establishments of the
debtor, to benefit common good of society, to public order and security situation at a local,
national and world economies.
As such, businesses can fall into default as a normal phenomenon and is the inevitable
consequence of market economy, correct and complete understanding of this concept is an
indispensable requirement of all stakeholders in the economy. This concept is the basis for the
State may intervene in the sense of this phenomenon to minimize the negative consequences
and exploit the positive aspects, the identification of risk owners able in the economy when
engaging in economic activities, as input data in risk management especially in credit rating.
So, according to Article 2 of bankruptcy laws in 1993 and Clause 1, Article 3 of Decree 189
of Vietnam has given this concept: The enterprise, cooperatives are likely to fall into default
if:
- Difficulty or loss of business;
13
- Losses in two consecutive years is not enough to repay the debts, not paying adequate wages
for workers under labor agreements and labor contracts in three consecutive months;
- Has applied the necessary financial measures but unable to pay debts.
In practical implementation shows that conditions can determine the condition can fall into
default of such enterprises is very complicated, causing difficulties for the opening of
bankruptcy procedures. In order to overcome this limitation, the Bankruptcy Law in 2004 has
defined the direction of simplifying the criteria for bankruptcy. According to Article 3 of the
"enterprise, cooperatives are not able to pay these debts when the creditors require it
considered default." Thus, this criterion has been defined simply than before, easily
implemented because not based on time loss, the cause of loss. Although this concept is the
more complete than Bankruptcy Law in 1993 but is still limited in its properties thoroughly.
Article 3 Bankruptcy Law in 2004 does not clearly define debt and overdue time not makes
the payment obligations of the debtor. So in form, the debtor simply as a debt the amount of
overdue payments and a day after creditors petition debt may also be considered default. This
can lead to abuse the right to file petition for bankruptcy procedures from creditors.
Experience of some countries in building concepts capable of default by quantitative often
have quantitative regulations on specific debt, the time delay debt payments from the debtor
after creditors when debt requirements. For example:
Bankruptcy Law of the Russian Federation debt provisions not less than 100,000 rubles to the
creditor is 10,000 rubles for legal entities and individual creditors.
Under the Australian Corporations Act, the creditors may request the court to decide to start
the procedures for payment of assets of a company due to a likely fall into default if company
has a debt to term of at least AUD $ 2,000 and the company cannot prove ability to pay such
debts.
According to Basel II, default is seen as events or incidents relating to the borrowing entity,
when at least one of the following possibilities occurs:
- Inability to pay debt obligations as to repayment or loss of ability to pay debts, including
loans and loan interest rates.
- Inability to perform duties as credit overdue for more than 90 days.
- The value of assets less debt
- Require open bankruptcy procedures or similar protection from creditors.
In the opinion of many experts, the definition of default "is probably the most difficult for
lawmakers." Therefore, in this thesis refers only to the business identification signs are likely
to fall into default as follows: The business is likely to fall into default as "Difficulty or losses
in business activity"

3.2 Data description
In this study, we used audited annual financial statements of enterprises listed on Ho Chi
Minh City Stock Exchange and Hanoi Stock Exchange in the period 2005 - 2010. Source data
is provided by Stockplus Financial Media Corporation and the Website: http://www.hsx.vn
and http://www.hnx.vn.
At the industry level, we have statistical proportion of the sample (we used sector class – level
2 in this thesis) with percentage as follows:
Figure 1: Ratio of Sectors in the research sample
From the figure above, we can see that “Foods & Beverages” and “Constructions &
Materials” are two sectors which largest ratio.
As per default definition above, we gathered financial data of all Vietnamese listed enterprises
from the year 2005 to 2010 with separate to two groups “default” and “non-default”2.
3.3 Selection of the sample
From initial data above, after excluded enterprises operation in financial sector that is not
representative, we randomly select a sample of two equal groups: forty-one “default”
enterprises and forty-one “non-default” enterprises to create a balanced sample of eighty-two
enterprises - forty-one enterprises in each group. The names of sampled enterprises are

provided in Appendix III3. “Default” Group (1) consists of enterprises fall into a loss in the
period 2005-2010. These enterprises have average asset size is 966.34 billion VND, with the
range varied between 17.80 and 10,797.31 billion VND. “Non-default” Group (0) consists of
enterprises selected based on stratified random (by industry and by size), with average asset
size of these enterprises is 1,067.59 billion VND and asset size range between 45.90 and
12,304.54 billion VND. Enterprises in the “non-default” group (0) are the enterprises
continuously profitable operations for the period 2005-2010.
In this sample, there are 10 default enterprises from “Food & Beverages” sector; the same 8
form “Industrial Goods & Services” & “Constructions” sectors; 4 from “Basic resources”
sector; the same 3 from “Information Technology”, “Property” & “Electricity, Water, Gas &
Oils” sectors and the same one from “Chemicals” & “Tourism & Leisures” sectors.
In this thesis, we used 39 ratios calculated from financial statements of enterprises in this
sample. We classified these variables in five ratios categories: leverage, liquidity, operating,
profitability and efficiency.4 Statistical summary for these variables are shown in Table 5.
5
Quality of input data is good because all annual financial statements are audited.
3.4 Selection of variables
To apply the analysis to distinguish, in the process of building a model to identify which
variable is the independent variable and dependent variable.
Dependent variable
Dependent variable has many categories, each category represents a group and makes this
able to distinguish the best and only on the basis set of independent variables was selected,
and in other words, each observation must be arranged into a single group. In this study the
dependent variable (Y) are selected as follows:
Independent variables
After choosing the dependent variable, the next step to identify independent variables will be
used in the analysis. The selection of independent variables is usually carried out in two ways.

If businesses not default

The first approach is based on theoretical grounds and from previous studies. The second
approach is based on intuitive knowledge of experts and intuitive selection of variables is the
first study and a reasonable theoretical basis. In both, the independent variables were selected
as the variables that affect the ability to distinguish between groups of dependent variables.
We set out a list of twenty-two variables (ratios) are potentially useful for evaluation. These
variables are categorized into five groups the ratio of the standard, including the leverage
ratio, liquidity, operating, profitability, profitability and Efficiency. The ratio is selected based
on: (a) the popularity of literature and (2) the potential relevance of this study.
Definitions and formulas for variable calculations can be found in Appendix I.
3.5 Methodology
In practice, discriminant analysis was widely applied to evaluating default for enterprises.
However, if the data is qualitative, it is not realizable to apply discriminant analysis. This
model is only suitable for the analysis of financial criteria, because the annual financial
statements of enterprises, data about the business activities are quantitative data. One
advantage of using discriminant analysis model to other classification procedures is that
discriminant function is linear and individual coefficients can be expressed in economic
terms. Those are the reasons why we use a multiple discriminant analysis (MDA) to estimate
Z-scores as the basis for the classification of enterprises of different industries with different
scales are more or less risk to answer main research question and sub-question 1 and 2 above.
Multiple discriminant analysis model is built based on discriminant analysis (DA). The
overall objective of discriminant analysis in evaluating default is to distinguish between
default enterprises and non-default enterprises in an objective and accurate way using the
discriminant function, variables are factors calculated from the annual financial statements.
The main objective is to find a system of linear combinations of variables to best distinguish
groups. Individuals in each group were closest and groups are best distinguishing (most
apart). The main content can be summarized as follows:
Suppose there is a set of n observations (enterprises) divided into two groups: default and
non-default group. Group Di have ni individuals, i = 1,2 on each individual we measured the
value of variable X1,…, Xp. yijk denoted to values of individual j of Di; i = 1,2; j = 1, ..,ni; k =
1, ..,p. Assume that ni> p; n1 + n2 = n.

Assume that all clouds are focus into the center, so we have kijkijk Gyx
Then, we denoted Xn,p is a matrix with n rows and p columns set up with a table data set of all

We can calculate the internal inertia matrix groups (internal inertia) as follows:

Since the inertia matrix of the entire cloud equal to the sum of the internal and external inertia
matrix, we have: T = W + B
For each individual j of Di groups, we set a linear combination of variables focused into the
center X1, ..., Xp; we denoted: i

The variance of a is a linear combination of variables X1, .., Xp, equal to total internal and

maximum external inertia and minimum internal inertia. In other words, we looking for a

distinguish enterprises between default and non-default as accurate as possible.
This problem is equivalent to the maximum problem of Lagrange function:
L = a’Ba- (a’Ta-1) Max
There are only two groups, so we can use the Mahalanobis method to solve the problem:

Multiple discriminant analysis determine linear combinations of two or more independent
variables that are best able to distinguish between groups known before, in our study is the
default enterprises and non-default enterprises. This is done by a rule of decision is to
maximize the statistical variance between groups compared with the variance within the
group. This relationship is expressed as the ratio between the variance of variance between
groups with internal groups. In this case, we have two groups, thus, a linear discriminant
function is constructed to differ two groups. Analysis of the distinction drawn from a
combination of linear equations has the following format:
Z = α + β1X1 + β2X2 + … + βnXn (1)
Where: Z: Overall index
X1, X2, …, Xn are independent variables as defined in Appendix I.
β1, β2, …, βn are regression coefficients.
20
Therefore, each enterprise received a combination of unique distinction, then it will be
compared with the threshold value to determine which companies belong to any groups.
In fact, the experiments show that the default enterprises especially frequent violations of the
standard conditions. Besides, the group condition of equal variances is violated. In addition,
the nature multicollinearity between the independent variables is also a serious problem,
especially when we use step-by-step procedures. However, experimental studies have shown
that the problems associated with the standard assumptions only little effect on the ability to
classify as well as the predictability of this approach.
The two methods most commonly used to draw the discriminant model is the “simultaneous
method (enter independents together)” and “stepwise method”. The first method based on
modeling as theoretical background, so the model can be determined from the beginning and
then use the analytical distinction. When applying the stepwise method, this procedure will
select a subset of variables to derive a good discriminant model using the selection first,
remove back, or select each step. Stepwise method that we use the built-in SAS programs.
Selection step begins with the number zero in the model variables. At each step, if the
variable contributing the least to the distinguish ability of the model, as measured by Wilks's
lambda coefficient, it will not meet the criteria to stay and will be removed. Variables that
contribute most to the ability to distinguish of the model will be added. The stepwise process
stop when could not find any way to add or remove variables may increase the ability to
distinguish of the model.
With two groups: “default enterprises” and “non-default enterprises”, this analysis is only one
dimension (simplest form of discriminant function). Discriminant function change variable
values into a separate unit or we can use Z-value to classify objects. MDA calculated
discriminant coefficients, βj, while the independent variable Xj is the real value. here, j = 1, 2,
... n.
To answer the sub-question number 3, we use a simple regression model in which, Z-Score
(calculated from MDA model above) are dependent variables and “TotalAssets” and
“TotalDebts” are independent variables. The regression model has the form as bellow:
Z-score = α + β1TotalAssets + β2TotalDebts + ε (2)
21
Chapter 4: Estimation results
4.1 Estimation results
We use stepwise discriminant analysis to find the most significant variables to predict default
and find the best prediction set of the variables. With this method, the independent variable
has the highest correlation was taken first, then, from step 2 onwards, the addition or removal
of a variable based on the level of significance based on the level for “F to remove”. This
process continues until no longer find a plan of adding or removing a variable that can
significantly increase the coefficient is measured in "canonical R squared".
4.1.1. Group statistics tables
Discriminant analysis is only meaningful if between the two groups: “default” and “non-
default” have a significant difference. Therefore, we used analysis of variance (ANOVA) to
test if there is significant difference between groups of each independent variable or not. If
there is no significant difference between the two groups, the results are not meaningful and
conducting any further analysis has no value. These information provided in table 6: The
Group Statistics6 and table 7: Tests of Equality of Group Means tables
7. Table 6 shows the
difference between the independent variables and Table 7 provide strong evidence of
statistical difference between the two groups: "default" and "non-default" with most of the
variables have high F values, in which, P3, E1 and P1 are variables with very high F-valued.
4.1.2. Log determinants and Box’s M tables
In discriminant analysis, the key assumption is the equivalent in covariance matrices. This
assumption can be tested by using Box’s M tables, which test the null hypothesis: “covariance
matrices between groups do not differ”. In our analysis, Box’s M is 169.4 and F-value =
16.024 and the result show that is significant at p <.000 (Tables 8 and 9)8. Log determinants
were quite different and Box’s M showed that the assumption of equivalent in covariance
matrices was not violated. With samples large enough, it is not too important to have a
significant result.
6 See Appendix V – Table 6
7 See Appendix V – Table 7
8 See Appendix VI – Table 8 and 9
22
4.1.3. Stepwise statistics tables
There are four steps were taken in this analysis (see Table 10)9. Each step included only one
variable, and finally, four variables: P3, O4, Li1 and Li3 were added to the discriminant
function to have the highest predictive power.
4.1.4. Wilks’ Lambda table
All four variable added to the discriminant function are significant with p-value <.000 (see
Table 11)10
. It means that predictive power of the discriminant function was increased when
adding these variables. Wilks’ lambda indicates the significance of the discriminant function.
Table 1211
shows a highly significant of discriminant function (p < .000). From this result, we
have 24.5% unexplained.
4.1.5. Table of eigenvalues
Table of eigenvalues showed that one canonical discriminant function was used in the
analysis because we used only two groups: Group (0): “non-default” and Group (1) -
“default”. The canonical correlation (which indicate multiple correlation between the
predictors and the discriminant function). In our research, canonical correlation = .86912
show
that the model explains 75.52% of the variation in classifying an enterprises to “default” or
“non-default” groups.
4.1.6. The Standardized canonical discriminant function coefficients table
Similar to multiple regression, the coefficients and the sign of each predictor were showed in
Table 1413
. P3 - score (.825) was the strongest predictor, Le4 (-.271) (– sign) was next. O4
and Li3 score were less successful as predictors and have strongly predicted allocation to the
“non-default” or “default” group.

10 See Appendix VIII – Table 11
11 See Appendix VIII – Table 12
12 See Appendix IX – Table 13
13 See Appendix X – Table 14
23
4.1.7. The structure matrix table
Relative importances of predictors are shown in Table 15. Here we have P3 and Le4 are the
most important predictors to classify an enterprise to “non-default” and “default” group.
Generally, in this table, 0.35 is seen as the cut-off between important and less important
variables.
4.1.8. The canoncial discriminant function coefficient table
From (Table 16)14
with unstandardized coefficients, we have a discriminant function as
bellow:
Z = - 1.046 - 0.1438 Le4 + 1.631 Li3 + 0.35 O4 + 8.756 P3 (3)
The correlation matrix among these four independent variables15
shows that no couple of
variables has perfect multicollinearity.
4.1.9. Group centroids table
In this discriminant function, we have group centroids is projected onto the coordinate axes
with the value 1.735 (Group 0) and -1735 (Group 1). Group means of predictor variables
(called group centroids) can be found in Group Centroids table16
. In this research, mean of
“non-default” group is 1.735 while “default” group have a mean of -1.735. In the next step,
enterprises will be classified as follow: Enterprises have scores near to 1.735 are predicted
belong to “default” group and enterprises have scores near to -1.735 are predicted belong to
“non-default” group.
4.1.10. Classification table
The classification results of enterprises belong to “default” or “non-default” group in Table
1917
showed that 98.8% of enterprises were classified correctly into “non-default” or “default”
groups. We can conclude that the discriminant function is very good.

4.1.11. Estimate results
All the predictors Le4 (Total debts / Total assets), Li3 (Current assets / Total assets), O4
(Accounts Receivable / EBIT) and P3 (EBT / Total assets) have significant mean differences.
Log determinants were quite different and Box’s M showed that the assumption of equivalent
in covariance matrices was not violated. The discriminant function explains 75.52% of the
variation in classifying an enterprise to “default” or “non-default” groups and results of
classification accuracy between the two groups was 98.8%. Group 0 (non-default) has the
accuracy rate is 100.0% and group 1 (default) have the accuracy rate is 97.6%

4.2 Discussion about Estimation results
4.2.1. Factors determine default for Vietnamese listed enterprises
We use multiple discriminant analysis (MDA) to distinguish “default” enterprises and “non-
default” enterprises in an objective and accurate way by using the discriminant function,
which variable is the financial criteria. The main objective is to find a system of linear
combinations of variables to distinguish enterprises to 02 groups: “default” and “non-default”.
Using this method, we estimated discriminant function with the results as follows:
Z = - 1.046 - 0.1438 Le4 + 1.631 Li3 + 0.35 O4 + 8.756 P3 (3)
Where:
Le4 = Total debts / Total assets
Li3 = Current assets / Total assets
O4 = Accounts Receivable / EBIT
P3 = EBT/ Total assets
Z = Overall index. The function Z is a combination of these indicators, the higher the
Z index indicates that companies have good financial situation, good business
performance, high profits and good liquidity.
The results indicate signs of the coefficients of independent variables in the discriminant
function are consistent with economic theory. By testing hypothesis H0: Discriminant
function is not significance. We can reject the hypothesis H0 and conclude that the
discriminant function is highly significant (p < .000) based on Wilks’ lambda (see Table 12).
With a distinguished function Z for the results of classification accuracy between the two
groups was 98.8%. Group 0 (non-default) has the accuracy rate is 100.0% and group 1
(default) have the accuracy rate is 97.6% (see Table 19). Thus, we can claim that the ability to
distinguish between the two groups regardless of the function obtained as well (greater than
25%). The results indicate signs of the coefficients of independent variables in the
discriminant function are consistent with the economic theories. Since:
Le3 (Total debts / Total assets) is a factor of the leverage group. This factor shows how much
the assets of the business are financed with debt. Through this ability to know the financial
autonomy of enterprises. This ratio that is too small, suggesting that businesses borrow less.
This may imply that business is capable of high financial autonomy. However, it can also
imply that enterprises in not good in use of financial leverage. In contrast, this ratio is too high
implies that the level of business risk is higher because of heavily rely on borrowed funds. If
this ratio is too high, businesses vulnerable to falling into the loss of liquidity and these
enterprises will be more difficult to raise loans for new projects.
26
Li3 (Current assets / Total assets) is a factor of the liquidity group. The positive sign of this
factor supports that enterprises with more current assets have lower probability of default. In
theory, enterprises with higher liquidity have lowered the ability of default. Current assets
includes all assets can be easily converted to cash in a short time (within one year). Current
assets include cash and cash equivalents, accounts receivable, investments in short-term
financial, inventory and other liquidity assets. Current assets are very important in business
operations because they are used for daily operations and pay for the daily costs. Thus, the
rate of current assets / total assets lower will cause enterprises to meet certain difficulties in
production and business activities, such as lack of working capital, lack of source to pay
incurred costs or lack of money to pay due debts.
O4 (Accounts Receivable / EBIT) is a factor the operating group. EBIT (Earning before
interest and tax) is often referred to as "operating income". Accounts receivable / EBIT
evaluate the customer's payment for goods and services that businesses provide. Besides, in
theory, accounts receivable can be converted into cash quickly; therefore, this factor has
negative relationship with default.
P3 (EBT / Total assets) is a factor of profitability group. EBT / Total assets is an important
indicator to show how effective exploitation of assets. Normally, we would expect this ratio
as high as possible and of course, the higher this factor indicate that the operation of
enterprise more efficiently, and therefore less risk of default.
Hence, four factors Le4 (Total debts / Total assets), Li3 (Current assets / Total assets), O4
(Accounts Receivable / EBIT) and P3 (EBT/ Total assets) determine default for Vietnamese
listed enterprises. The main research question was answered.
The function Z is a combination of these factors, higher Z-score indicates that enterprise has
demonstrated good financial situation, business performance, high profit and good liquidity.
4.2.2. Enterprises classification depend on Z-Scores
From estimated results, we have a table with Z-scores for enterprises.18
With a distinguished function Z for the results of classification accuracy between the two
groups was 98.8%. Group 0 (non-default) has the accuracy rate is 100.0% and group 1
(default) have the accuracy rate is 97.6% (see Table 19). Only one enterprise: Thang Long
Investment Group (TIG) with Z-score 0.42 (>0) was classification to default group. Thus, we
can claim that enterprise with Z-score from 0 to 0.42 may have probability of default.
Therefore, we can separate enterprises based on Z-scores to 03 groups: “Safety” group
(without probability of default for enterprises have Z-scores >0.42; “Alert” group (may have
18
See Appendix XV – Table 20
27
probability of default) for enterprises have Z-scores from 0 to 0.42 and “Danger” group (have
high probability of default) for enterprises have Z-scores < 0.19
4.2.3. Determine risky sectors based on Z-Scores
To answer the sub-question number two “Which sectors are more risky?”, we based on
average Z-Scores estimated (See table 20). In this thesis, we used sector class – level 2 and
calculated average Z-scores for all sectors.20
From Table 22, we can see that “Chemicals”, “Information Technology”, “Industrial Goods &
Services” are sectors with highest risk in nine sectors of the research sample with the average
Z-Scores are respectively -0.84, -0.47, and -0.41. These sectors suffered impact from raw
material price fluctuations on world markets and from increased exchange rate volatility
(VND/USD) in recent years. "Foods & Beverages" and "Constructions & Materials" are lower
risk sectors with the average Z-scores -0.09 and 0.09 respectively. These sectors least affected
by fluctuations in world market and exchange rate fluctuations because most products and
services of these sectors are served domestic market. "Electricity, Water, Gas & Oils",
"Tourism & Leisures", "Property" and "Basic Resources" are sectors with lowest risk in the
nine sectors of the research sample with the average Z-scores respectively 0.81, 0.46, 0.44 and
0.37. These sectors have certain natural advantages and have exploited these advantages in
recent years quite good.
4.2.4. How the scale of the businesses affect to Z-scores
We use a simple regression model:
Z-score = α + β1TotalAssets + β2TotalDebts + ε (2)
To answer for the sub-question number three “How the scale of the business affect to risk?”.
The results can be found as bellow:
.reg zscore Totalassets Totaldebts
Source SS df MS Number of obs= 82
F( 2, 79) = 3.01
Model 23.1610209 2 11.5805105 Prob > F = 0.0549

See Appendix XVI – Table 21 20
See Appendix XVII – Table 22

_cons -.0010379 .2402357 -0.00 0.997 -.479215 .4771392
From these results, we can see that TotalAssets has a positive relationship with Z-scores that
implied that increase total assets would increase Z-scores. TotalDebts has a negative
relationship with Z-scores that implied that increase total debts would decrease Z-scores.

Chapter 5: Summary, limitations and suggestions for
further researches
5.1 Summary
This study used annual financial statements of over 600 enterprises listed on Vietnamese
stock markets from 2005 to 2010 to examine the reliability MDA approach to predict the
default for Vietnamese listed enterprises. The results of the study also help banks to better
control risk when lending out for Vietnamese listed enterprises.
The results of this study indicate that a combination of financial ratios together can help us
predict the likely default of enterprises in Vietnam and consistent with previous studies. In
this study, we found that four explanatory variables, Le4(Total debts / Total assets), Li3
Current assets / Total assets), O4 (Accounts Receivable / EBIT) and P3 (EBT/ Total assets)
were significantly in evaluating the probability of default. From this research results,
enterprises’ administrators can identify the factors that would affect their likelihood of default
to have appropriate policies to improve financial capability of their enterprises to avoid the
risk of default.
Besides, the results for this thesis suggested that based on Z-scores, we can separate
enterprises status to three groups: Without risk of default (safety) for Z-scores > 0.42; May
have risk of default (alert) for 0 < Z-scores < 0.42 and high risk of default (danger) for Z-
scores < 0.
In addition, the results for this thesis suggested that some sectors are less risky than other
sectors. “Chemicals”, “Information Technology” and “Industrial Goods & Services” are
sectors with highest risk while "Electricity, Water, Gas & Oils", "Tourism & Leisures",
"Property" and "Basic Resources" are sectors with lowest risk in the nine sectors of the
research sample.
Moreover, these results sound reasonable as scale of enterprises affect to risk in which higher
debts will bring to higher risk (decrease Z-score) while higher total assets will bring to lower
risk (higher Z-score). It is consistent with practices. When increase scale, enterprises will be
able to reduce input costs, improve competitiveness and open market shares. Moreover,
increase asset size through increase equity will help enterprises more strengthen, reduce the
pressure of interest payments. On the other hand, if such enterprises increase scale through
increase debts, the risk is increased because pressure to pay principal and interest on time
increase.

5.2 Policy implications
Z-Score is an important tool to assess the stability of the financial situation of enterprises.
Depending on the type of business, field production and business activities that evaluation
methods are slightly different. Elements sector management, business environment, marketing
strategies, management policies will be reviewed by the general index reflecting the financial
situation of enterprises. So Z-Score is used as an indicator reflects the trust of investors, banks
and enterprises’ managers of the financial situation of enterprises.
For investors, the choices of enterprises have a healthy financial situation for investment is a
top priority in making investment decisions. For the field of financial investment, investment
decision making requires a lot of information related to financial business. In Vietnam, the
majority of investors do not have a method to analysis the financial health of the business. A
method of evaluating the financial health based on combining the many indicators is the
problem that the majority of investor interest. My model has solved the problem of investors.
Based on scores Z-Score, investors can assess the business would have good financial health,
but any business is high risk and make investment decisions the right way to more
transparent. Advantages of this approach are that only use data of financial statements of
listed enterprises therefore helpful to investors in analyzing individual stocks of enterprises
they invest.
For banks, this research can help banks to classify businesses located in safe areas, not in
danger or alert of default. Necessary using this method to evaluating the capacity to business
credit situation. Z-Score is relatively simple but highly reliable, has been widely applied in the
U.S. and investors are gradually being used by the test results reliable. Thus, my model can
help banks can to decide the credit limit required for each business. Z-score can be regarded
as a powerful support tool for banking executives has the right decision before granting credit.
Therefore, when determining credit for businesses, banks need more careful scrutiny of the
financial status and ability of the enterprise default.
For enterprises’ managers, through the research results show that Z-Score depends primarily
on total assets. Therefore, managers can increase Z-score by:
- Financial restructuring towards increasing equity, decreasing debts by limit corporate
debt, issue additional shares. Implementing this solution will decrease Le4 (Total
debts/Total assets).
- Efficient use of enterprises’ assets through classified assets and liquidate all assets that
do not contribute directly or indirectly create revenue. Sale off inefficient assets will
increase current assets, increase Li3.
- Improve efficiency of production and business activities of enterprise will increase P3.
31
The implementation of these solutions to improve Z-score does not only mean immediate
action, but also can lead to improve Z-score in the future. Increase Z-score will improve
investor confidence, and therefore, enterprise will be easier in the issuance of shares, capital
restructuring. Additionally, when Z-score improves, customers will also look more
sympathetic to enterprise, thus, enterprise will be easily accessible business opportunities.
Therefore, enterprises should pay more attention to Z-score and should create a long-term
plan for improve Z-score.
5.3. Limitations and suggestion for further researches:
The concept of business fall into default (default) in Vietnam is lack of quantitative properties
that should generate many difficulties in defining and applying this concept in reality.
Therefore, the next time should have modified the concept of business fall into default in the
direction of quantifying these criteria.
The study also has limitations because the sample size is not big enough. This limitation has
two reasons: the first reason is the number of listed enterprises, the second reason is most
listed enterprises are profitability enterprises because listing conditions require two years
previous profitability (listed on the Ho Chi Minh Stock Exchange) and one year ago
profitability (listed on the Hanoi Stock Exchange). Therefore, the construction of balanced
sample for this study is restricted.
Although there are limitations, this study showed default prediction indicators to create a
discriminant function for Vietnamese listed enterprises. The results of the study are acceptable
and applicable in determining the likely default of enterprises listed on the Vietnam stock
market. Therefore, Z-score in this study can be used as a tool for the classification of
enterprises, thereby helping to investors, banks and enterprises’ managers decided more
rational policy.
Through the limitations of this study, researchers can discover new research directions in
order to complement the research on enterprises’ default in general and about the default of
Vietnamese enterprises in particular. Suggestions for future researches are follows:
There should be the study of signs of enterprises are in danger of bankruptcy based on
the actual amount in accordance with Vietnam.
Should have in-depth study estimates the probability of insolvency of enterprises in
each economic sector.
Continued modeling studies that the ability of insolvent enterprises under the new
approach suited to the conditions of asymmetric information in the current economic
relations.
32
Furthermore, derived from actual empirical studies of the thesis and the inadequacies of
research on default in Vietnam, the authorities should have some specific solutions. In our
point of view, we have solutions as bellows:
Firstly, lawmakers should create a legal system in accordance with actual conditions in
Vietnam, ensuring the operation of research on default as well as the regulations required the
relevant to the organization and operation of research on default. The legal system must
reflect the viewpoints of the State, showing the way the Party's policies. The organization and
operation of safe and efficient securities market, insurance market, and gradually expand the
scope of activities, including attracting foreign capital.
Secondly, Vietnam's stock market has been developing towards a stable process. The fact that
in many countries, evaluating default of listed enterprises is one of the factors that ensure the
stock market of that country stable development. Therefore, government should encourage the
formation of independent organizations research on default.
Thirdly, the authorities should have rules on disclosure and transparency of information to
progressively increasing levels of efficiency and perfection of the market. Thereby promoting
the development of activities to collect and publish information of Vietnam under the
direction of integration, establish common standards for research on default are more
favorable.
