ABSTRACTThe aim of this study is to determine the effects of loans
portfolio diversification on the performance of Marakwet
Teacher’s Sacco Ltd. The main objective of the study is to find
out how loan portfolio affects the performance, how does the
diversification influence loan sales, how it affects the
financial position and the customer base. Members of Sacco’s have
been affected by different loans offered by SACCOs this makes the
management to be on the run introducing different loans to their
v
customers. For a Sacco to be able to effectively compete with
other upcoming banking institutions it must among other things
introduce a variety of services so as to improve its objective
achievement for both members and management. This may not work
well until an optimal level of loans portfolio diversification is
reached.
The study employed a case study research design which is believed
to be an intensive descriptive and holistic analysis of the
single entity. The study targeted a population of 49 which
consisted of Junior Employees 39 and Management level employees
10. From the targeted population stratified sampling was used to
pick the sample size for the study. I used questionnaires and
interviews as data collection instruments. Microsoft Excel was
used to capture the data then analyzed by tables and graphs.
The study established that the loan portfolio diversification has
an effect on the SACCO performance and there are some challenges
faced in the management of the portfolio like inadequate sales
promotion strategies, customer preferences and choice, customer
inadequate information on various loans and iintense competition
from other SACCOs. The study recommends the following as
necessary to make loan portfolio diversification successful.
Undertake effective sales promotion to help customers understand
various loans offered and the SACCO should try to educate its
customers on the benefits of other loans as per the circumstance
so that to have good balance on all the loans offered. I
vi
recommend also further research into the sector to ensure that
the strategies work effectively and a research be done to
identify the effects of management skills of the employees on the
performance and the same should be done on the banks.

1.0 INTRODUCTION
1.1 Background of the study
Co-operative is an autonomous association of persons united
voluntarily cooperate or their mutual economic, social, cultural
needs and aspirations through a jointly owned and democratically
controlled enterprise. A cooperative society is a business entity
geared towards the promotion of the Welfare and economic
interacts of their members and this is in turn will contribute
towards the attainment of the overall national development goals
of poverty alleviation and wealth creation. Cooperative Values
has it’s based on: self-help, self responsibility, decorative
control, equity, equality and solidarity. In the tradition of
their founders, cooperatives members believe in the ethical
values, honesty, openness, social responsibility and caring for
other.
Cooperative principles are the guidelines by which cooperative
put their values into practice and also determine the attitude
that provides the movement with its procedures and distinctive
characteristics. These include; voluntary and open membership,
democratic member control, member economic participation,
autonomy and independence, education, training and information,
cooperation among cooperatives and concern for the community
xi
1.1.1 Concept of SACCOs in Kenya
The cooperative movement in Kenya was started by the European
farmers at Lumbwa. Kipkelion in Kericho district in 1908. It was
aimed at promoting production and marketing. Those formed by
Africans were not recognized until 1930’s when the colonial
government had a change of heart. In 1940s the British government
agreed to introduce cooperative in Africa colonies. Consequently,
Kenya enacted the cooperative ordinance in 1945 followed by the
creation of a department under the registrar of cooperatives in
1946, whose objectives were to form and promote form produce then
market the idea of marketing cooperative in Africa land units.
After independence, the cooperative movement assisted in
mobilizing and raising the necessary capital for the acquisition
of business and forms, formerly owned by European settlers. A
need for a ministry responsible for development and guidance of
expanding cooperative movement arose. Hence the formation of the
Ministry of Cooperatives Development and Marketing in 1963.
Much recognition was given to the cooperatives as a tool of
development in 1965 with the government’s policy paper: seasonal
paper number 10 of 1965. The governments realized that the
cooperatives could be used as a tool of attainment of African
socialism by Africans. This led to the enactment of cooperative
xii
society Act of 1963 CAP 490 (Revised in 1967) which made the
provision for appointment of commissioner for cooperatives.
In 1997, the government introduced a new cooperative societies
Act number 6 to govern the operation of cooperatives under a
liberalized economy. As a result the government reduced its power
of influence and left the cooperatives to exercises some self-
regulation without much interference.
An amendment of the cooperative societies Act of 1997 was made in
2004. Its aim was to improve the economy through cooperatives.
Thus the government continued, from then onwards, to emphasize on
the benefits of movement in Kenya since it uplifts the country’s
economy. (Gamba and Kono, 2003)
1.1.2 Concept of Loan Diversification
Portfolio diversification is the means by which investors
minimize or eliminate their exposure to company-specific risk,
minimize or reduce systematic risk and moderate the short-term
effects of individual asset class performance on portfolio value.
In a well-conceived portfolio, this can be accomplished at a
minimal cost in terms of expected return. Such a portfolio would
be considered to be a well-diversified.
Although the concepts relevant to portfolio diversification are
customarily explained with respect to the stock markets, the same
underlying principals apply to the loans investments. For
instance, loans have specific risk that can be diversified away
xiii
in the same manner as that of stocks.
1.1.2.1 Types of Loans Offered
Development Loans; It’s a loan whose maximum repayment period is
48 months. Interest rate is 1% per month on reducing balance. The
amount of loan awarded depends on deposits. Sometimes the SACCO
gives this loan three times the customer’s deposit. This deposit
may be in form of their shares in the SACCO or real deposit.
School Fees Loan; It’s a loan whose maximum repayment period is
12 months; this means that the loan only covers one year.
Interest rate is 1% per month on reducing balance, as the balance
goes down the amount of interest paid declines. Amount of loan
awarded depends on deposits, the higher the deposit the more the
amount loaned.
College Fees Loan; This resembles school fees loan but differs on
the loan period. It’s a loan whose maximum repayment period is 24
months. Interest rate is 1% per month on reducing balance. Amount
of loan awarded depends on deposits. It is convenient when it is
two years unlike one year in the above loan.
Emergency Loan; It’s a loan whose maximum amount issued without
documentation is Kshs. 20,000. Any amount exceeding this should
have supportive documentation. Maximum emergency loan amount is
Kshs 150,000.Interest rate is 3% per month on reducing balance.
Amount of loan awarded depends on deposits. This loan has less
xiv
processing time and paper work. The loan is not limited to any
period of repayment; however the loan is expensive when it is
held for a long time.
Development Loan; This loan is being offered for development
purposes. The amount of loan offered to members depends on the
number of shares being held by the member. Members are qualified
to have this loan upto three (*3) times the shares held by the
member. This loan is repayable within 36 months.
Salary in advance; It’s a loan whose interest will be charged at
the rate of 5 % flat rate and recoverable within one month and
this product only applies to those members whose salaries is
channeled through FOSA. This service is payable within 5 months
for members. The documentation that is required is the salary
slip. The loan is normally based on the salary expected. The
lender also faces some sort of risk and the urgency of the loan
making it expensive.
FOSA Loan; The minimum amount granted is Kshs 10,000 and maximum
amount is Kshs.500, 000. The maximum repayment period is 12
months. The interest rate is 1.5 % per month flat rate. This is
regarded to be the cheapest loan that can be advanced to a
member, based on the rate and the amount loanable. It requires
all necessary documentation for one to qualify for this type of
loan.

1.1.3 Marakwet Teachers Sacco
MARAKWET TEACHERS SACCO SOCIETY LTD was born through the
splitting from Keiyo/Marakwet Teachers Sacco Society.MTSS was
registered by the commissioner or for co-operatives development
on 3rd July 1996.The societies proponents visualized on the
future hence they sought to harness their individual resources
together to form a common pool from which they could raise their
fund to realize theire development goals. The society started off
with only 873 members but currently it stands at 5094 members.
1.1.3.1 Society catchment area.
The Sacco draws its membership mainly from employees of TSC and
those related institutions such as Education officers and members
of KNUT local branch. The Sacco has also opened the common bond
to include members of the civil service e.g. chiefs, clerks etc.
The proponents of this society visualized the future hence sought
to harness their individual resources together to form a pool
from which they could raise to realize their development goals.
The members are drawn from all over the region of Marakwet
districts (east and west) and other interested persons outside
the region who meet the terms and conditions of the Sacco. Some
delegates are elected to represent the SACCO in mattersxvi
pertaining the society and interests of members.
FOSA services are offered by the SACCO- these are banking
services such as FOSA loans, sms alerts, fixed deposits
facilities, cheque advance, M-banking, salary advance, ATM
facilities, and salary processing. Other FOSA products include: -
savings account, children’s account, medical account, Christmas
account, group account, cheque advance repayable at maturity of
the cheque,
1.2 The Problem Statement
Loan advancement is an integral part of Sacco’s income. The price
that customers pay for the loans makes the largest portion of
reported profits. Whether diversified Loan advancement has an
effect on the success of a SACCO is the most critical question in
SACCO’s operation. A diversified loan service means wider
coverage of the customers. Loan diversification results to
variety of loans on offer; this will impact on the demand. The
well-being ranking exercise seen in SACCOSs show that both poor
and well-off people are members of SACCOSs.
However, the membership size by well-being status differs due to
the products that the SACCOs offer. They are providing services
for a larger proportion of poor people than the self-promoted
ones. SACCOs are focused on providing their services, both social
and financial, for as many poor people as possible, whereas on
xvii
the other hand SACCOs mainly focused on providing financial
services, rather than social services for their members.
There are other problems that need to be to be addressed like,
loan delay due to loan procedures that negatively impact the
society’s loan policy. This is because of inadequate funds, some
incompetent staff who process loans according to whom they know
regardless of the members ability and erroneous loan application
by members due to misunderstanding especially by the members.
Variety loans or single loans the SACCOs management needs to
balance between different loans. This study endeavors to find out
which is the optimal loan diversification for the SACCO to
maximize on its performance.
1.3 Research Questions
In order to solve the research problem the following questions
need to be taken into account.
i. Does loan diversification influence loan sales?
ii. What are the types of loans offered by SACCOs?
iii. Does loan diversification directly affect SACCOs’
financial performance?
iv. Do the customers have any significant influence on
types of loans to be offered?
v. Does loan portfolio diversification influence the SACCOs
membership?

1.4 Significance of the study
Research findings of this study will be useful to the following
groups
Academics; Credit and portfolio diversification is an area of
study in colleges, universities and other private studies. This
group will use the research findings to broaden their
understanding on issues relating to portfolio diversification and
credit risks therein. Also the study will open up areas, which
need further research.
The financial analyst; this study will help since they will get
additional information for their clients. It will also help them
in preparation of their annual bulletins or professional
magazines. Stockbrokers need it to advice investors.
The public or shareholders; by undertaking this study, members
and shareholders will understand the need for diversification,
the type of portfolio diversification that is optimal. It also
helps potential customers in their decision-making.
SACCOs; SACCOs can compare their loan diversification and
performance using findings of this study whether the policy is in
the view to maximize the wealth of their shareholders.
The government agencies; this enables the government agencies to
know the tax payable by the SACCO in view of interests charged on
loans.
To the management; this study will enable to guide the management
xix
in designing an effective diversification policy. Effective
diversification policy assists in realization of the objective of
the firm that is maximization of profits. This study will help
management not only exercise the management on the degree of
judgment to establish a sound policy and also in timing of
investment opportunities.
1.5 Scope and Delimitations of the study
The data being used is taken from primary source originating from
the Marakwet Teacher’s Sacco staff therefore the data is only
relevant and can only be used fully by Marakwet Teacher’s Sacco,
the result and the interpretation are completely rigid and from
the viewpoint of the researcher. Among the different aspect of
SACCO disbursement only loan diversification is taken for
consideration, the data being taken into account only relates to
the financial information of Marakwet Teacher’s SACCO Limited
before and after loan portfolio diversification.

CHAPTER TWO
2.0 INTRODUCTION
2.1 Review of Theories
2.1.1 Trade Theory and Structural Diversification
Economic sectors generate positive externalities and that these
externalities may not spread rapidly around the globe and can act
as a constraint to structural diversification since they cause
technological disparities to persist. The traditional
interpretation of comparative advantage is based on the
assumption of constant returns to scale, that’s when inputs to
production are doubled output doubles as well. In the presence of
economies of scale, the larger the scale on which production
takes place, the more efficient is productions meaning doubling
the inputs to production will more than double its output.
Economies of scale at the firm level, internal economies of
scale, must be distinguished from those occurring at the sectoral
level, external economies of scale or external economies, in
xxii
order to analyze their impact on market structure and structural
diversification. "External economies of scale occur when the cost
per unit depends on the size of the sector but not necessarily on
the size of any one firm. Internal economies of scale occur when
the cost per unit depends on the size of an individual firm but
not necessarily on that of the sector, (Krugman and Obstfeld,
1994).
Internal economies of scale allow large firms to obtain a cost
advantage over small ones and are therefore likely to give rise
to an imperfectly competitive market structure. By contrast,
external economies of scale need not lead to imperfect
competition because individual firms may remain small, even
though important advantages for the large scale arise at the
sectoral level.
The limited size of a market constrains both the variety and
quantity of services that a country can produce efficiently when
there are internal economies of scale. Firms operating on a
relatively large domestic market will tend to have more sales and
hence lower average unit costs than those operating on a small
domestic market. Given their cost advantages, these firms will be
more competitive on international markets and therefore find it
easier to establish export activities. This suggests that
countries with a relatively large domestic market will find it
easier to diversify into activities were internal economies of
scale are large. Economies of scale arise at the sectoral rather
than at the firm level, for example when production is
xxiii
concentrated in one or a few locations, thereby reducing the
sector's cost without necessarily affecting the size of
individual firms in this sector. The geographical concentration
of production sites may give rise to a local market for a greater
variety of support services for a larger supply of specialized
skilled labour, (Kamp, A., 2006)
The presence of strong external economies of scale tends to lead
to a situation where a country that has established a large
production of a good will produce it at a low cost, since its
producers are able to take advantage, for example, of the easy
and cheap availability of both support services and skilled
labour. This cost advantage constitutes a barrier to entry for
other countries to this sector even though the sector may have a
perfectly competitive market structure; this is because the
country that is trying to enter production in this sector will
not have the gradual accumulation of networks of firms that gives
rise to external economies, like the country with long
established activities in this sector.
The accumulation of knowledge is probably the main source of
dynamic scale economies. Dynamic internal economies of scale
arise when the costs of a firm depend on production experience,
that’s its cumulative output to date, rather than on the scale of
its current output. The inverse relationship between unit cost
and cumulative output can be expressed through a downward sloping
learning curve. Dynamic external economies arise when the
xxiv
improvement which an individual firm achieved in its products or
its production technique is imitated by its competitors; as a
result, knowledge spills over from the firm that initially
invested in knowledge accumulation to other firms that have not
made any specific investment in such knowledge.
Whether or not externalities in this learning process spill over
internationally has important implications for trade patterns.
With a full international spillover of learning externalities,
producers in all countries have access to the same body of
technical information; as a result, the accumulation of knowledge
through learning does not affect their relative abilities to
produce any specific good. A country's trade pattern must then be
determined by other factors, such as its initial conditions in
terms of factor endowment. By contrast, if the extent of
knowledge spillovers is limited to national borders, sector-
specific knowledge stocks accumulate in proportion to local
activity in this sector alone. Both domestic and foreign
producers learn and become more productive in sectors in which
they always have been active; as a result, initial patterns of
trade get locked in - history matters for the determination of a
country's opportunities for structural diversification. The
dismal conclusion would be that countries which, for whatever
historic reasons, are late-comers in the process of structural
diversification risk being trapped in a low-development
equilibrium Kamp et al ,2005
xxv
The initial advantage in structural diversification will
perpetuate itself and serve as a barrier to competitive entrants
is based on two assumptions: first, the learning-by-doing
benefits of skill-intensive activities are assumed to accrue
entirely to producers within a country, that’s knowledge
spillovers across national boundaries are assumed to be zero.
Where knowledge spillovers are concentrated within national
borders, countries' learning experience differ and the historical
coincidence of inheriting even a small lead in knowledge puts a
country in a position of self-perpetuating structural
diversification and development, thereby increasing the gap in
other countries. By contrast, where knowledge spillovers are
international in scope, other countries can share in the benefits
of knowledge accumulation and thereby improve their structural
diversification and development opportunities, provided their
social capability in knowledge absorption allows them to master
this knowledge. Second, the argument of the perpetuation of an
initial advantage in structural diversification is further based
on the assumption that learning-by doing is unbounded and that
therefore producing different goods is associated with
permanently differing learning potentials. The following chapter
will show that this latter assumption may be unrealistic.
xxvi
2.1.2 Classical Portfolio Theory
Classical portfolio theory in the sense of Markowitz (1952)
states that a portfolio is well diversified if there is no
portfolio which has, at the same time, lower risk and at least as
much expected return. However, this concept cannot be transferred
easily to loan portfolios for the many reasons. Fist, the
classical portfolio theory is based on mean-variance-efficiency.
However, the return distribution of loan portfolios is highly
skewed so that the variance is an inappropriate risk measure and
the mean variance-concept is no longer justified on the basis of
the expected utility theory. Secondly, even if the mean-variance
framework were appropriate for loan portfolios, the problem to
estimate the necessary input parameters would remain. In order to
determine the composition of mean-variance efficient portfolios
one needs, among others, the correlations of the portfolio’s
assets; but the correlations among loans cannot be estimated
precisely, at least with the limited data which we usually have.
Accepting the inappropriateness of the Markowitz-concept in this
context, we resort to more heuristic concepts and we use the loan
portfolio concentration and the loan portfolio’s distance to a
benchmark as diversification measures. In the context of
portfolio theory, an investor invests his money into different
assets, for the SACCO loaning to different industries, that’s
loans granted to firms of one industry are seen as one asset.
In the sense of Markowitz diversification is a means to change
xxvii
the risk of a portfolio. Keeping monitoring abilities and
monitoring costs constant, the default risk of a SACCO is likely
to decrease when a SACCO’s loan portfolio gets better
diversified. This view seems to be predominant in the German
financial institutions investment plans stipulating that a
SACCO’s sum of large loans is limited to eight times the SACCO’s
liable capital.
Winton (1999) shows that diversification does not need to lower
the SACCO s’ default risk. This model result is based on the idea
that specialized SACCOs can benefit from their screening and
monitoring advantages. However, it must be taken into
consideration that the results of the model rely to some degree
on the assumption that there are only two sectors in the model
economy. Thus, within the Winton model diversification is an” all
or nothing” decision. To explain the relationship of
diversification and return there seems to be a tradeoff between
the benefits from risk diversification and specialization.
Thus, the theory investigated the relationship of risk and loan
portfolio diversification. While return figures can easily be
derived from balance sheet data it is by far less clear how the
risk of a SACCO’s loan portfolio should be estimated. A common
approach to measure the SACCO’s risk is to use the loan loss
provision ratio (LLP) or the non-performing loan ratio (NPL).
Acharya et al. (2004) refer to these ratios as a measure for the
bank’s risk in the loan portfolio. They admit that this
xxviii
interpretation is questionable: The risk of a loan portfolio is
its unexpected loss, not the losses that are expected. However,
the denominators of the loan loss provision ratio and of the non-
performing loan ratio are also determined by losses that were
expected when originating the loans. Theses expected losses
should be reflected in a risk-adjusted pricing and therefore not
be considered as risk. Consequently, doesn’t only measure the
risk in the bank’s loan portfolio by the loan loss provision
ratio and the non-performing loan ratio but also by the
fluctuation of these variables in the course of time. The theory
defines the variables LLP and NPL as the standard deviations of a
bank’s loan loss provision ratio and non-performing loan ratio,
respectively.
nplb,t = _ + _ · smb,t−1 + 0 · zb,t−1 + μb + _t + "b (9)
In the regressions above, llpb,t and nplb,t denote the loan loss
provision ratios and the non-performing loan ratios of SACCO b at
time t, sm is one of our specialization measures, and z is a
vector of control variables. Again, μb and _t represent SACCO
individual and time individual fixed effects.
The specialization measures ‘sm’ are defined such that high
degrees of specialization are associated with high values while
low values stand for diversification. Therefore a positive sign
for the coefficient if diversification tends to reduce the risk
of a SACCO expected. On the other hand, if focused SACCO s tend
to identify effectively the low-risk borrowers and thereby reduce
xxix
their risk, we will find a negative relation between the SACCO s’
risk and their specialization measure.
2.2 Criticisms of the Theories
Should a bank diversify its loan portfolio or should a bank hand
out loans only to those groups whose income generation is very
familiar with? If a loan were a liquid asset with exogenous
payoff, the question would clearly be answered in favor of risk
diversification. However, loans cannot be traded in a liquid
market and the bank can at least in part determine the payoff of
the loan: Depending on its screening and monitoring abilities, a
bank can prevent or at least mitigate the information asymmetry
problems associated with the loan contract and can thereby reduce
the riskiness of the payoff.
The initial advantage in structural diversification will
perpetuate itself and serve as a barrier to competitive entrants
is based on two assumptions: first, the learning-by-doing
benefits of skill-intensive activities are assumed to accrue
entirely to producers within a country, that’s knowledge
spillovers across national boundaries are assumed to be zero.
Where knowledge spillovers are concentrated within national
borders, countries' learning experience differ and the historical
coincidence of inheriting even a small lead in knowledge puts a
country in a position of self-perpetuating structural
diversification and development, thereby increasing the gap in
other countries.xxx
2.3 Empirical Review
The theoretical literature on the question whether or not to
diversify does not offer an unanimous recommendation. Whereas
Diamond (1984) comes to the conclusion that a bank maximizes the
gains from delegated monitoring by perfect diversification,
Hellwig (1998) extends the Diamond (1984) model and shows that
banks may be well advised to concentrate at least on some large
projects to reduce the monitoring costs. Stomper (2004) shows in
an equilibrium model that both types of banks exist in
equilibrium: those that are perfectly diversified and those that
are specialized.
Winton (1999) explicitly models the tradeoff between
diversification and specialization. In his model the gains from
diversification and those from focusing depend on the riskiness
of the bank. According to his model the gains from
diversification are most dominant when the bank has a medium risk
level; for low risk and for high risk banks it pays to run a
specialization strategy. Whereas Lang and Stulz (1994) and Berger
and Ofek (1995) find a discount for diversified firms, Campa and
Kedia (2002) argue that this diversification-discount is rather
due to the underlying characteristics of the diversified firms
than to the decision for diversification. Stiroh (2004) and
xxxi
Laderman (2000) empirically analyze the benefits from strategic
diversification in the case of banks.
According to their studies the gains from diversification in
terms of reduced risk are only weak. Heitfield et al. (2005)
analyze portfolios of Syndicated National Credits (SNC). They
show that the portfolio risk goes up when the name and industry
concentration is increased. However, their results are barely
surprising because in their study the loan parameters are
exogenous and therefore the banks’ screening and monitoring
abilities remain unconsidered.
The empirical study of Acharya et al. (2004) is based on the
theoretical results of Winton (1999). They analyze the portfolio
diversification as well as risk and return figures of Italian
banks and conclude that “diversification, per se, is no guarantee
of superior performance or greater bank safety and soundness”.
Elyasiani and Deng (2004) carry out a corresponding study for the
banks in the United States. They find that diversified banks have
lower returns, but at the same time these banks are less risky,
hinting at a typical tradeoff of risk and return. Hayden et al.
(2005) perform a study close to Acharya et al. (2004) with data
for German banks. They find that diversified banks tend to show
weaker results than specialized banks. Their study is the one
most closely related to my own work.

2.4 Knowledge Gap
The portfolio composition in my study is calculated from the
borrowers’ statistics, whereas Hayden et al. (2005) use
individual loan data which is taken from the German credit
register. The problem with the credit register is that it only
covers loans of more than 1.5 million Euros, whereas the
borrowers’ statistics comprises all national lending.
Winton (1999) explicitly models the tradeoff between
diversification and specialization. In his model the gains from
diversification and those from focusing depend on the riskiness
of the bank. According to his model the gains from
diversification are most dominant when the bank has a medium risk
level; for low risk and for high risk banks it pays to run a
specialization strategy.
Lang and Stulz (1994) and Berger and Ofek (1995) find a discount
for diversified firms, Campa and Kedia (2002) argue that this
diversification-discount is rather due to the underlying
characteristics of the diversified firms than to the decision for
diversification. Little has been understood about the
diversification and its effects on profitability. This is the
reason for the study of diversification of loan portfolio by the
researcher to bring out the actual impact on profitability. Lack
xxxiii
of a clear explanation on the relationship of diversification and
profitability has left many loan managers guessing.

3.0 INTRODUCTION
3.1 Research Design
Kothari (2003) define the research design as what, when, how
much, by what means concerning an enquiry or a study. A research
design is the arrangement of conditions for collection and
analysis of data in a manner that aims to combine relevance to
the research purpose, a research design is the conceptual
structure within which research is conducted; it constitutes the
blueprint for collection, measurement and analysis of data.
The study applied a case study research design; as such it was an
intensive descriptive and holistic analysis of Marakwet Teachers
SACCO as a single entity. It is an investigation of single entity
in order to gain insight into the larger cases. According to Oso
(2005) in a case where the number of organizations that can be
investigated are few, a small sample is available and an in-depth
analysis is necessary, a case study is the most appropriate.
3.2 Target Population
The target population is the loan department employees of
Marakwet Teacher’s Savings and Credit Co-Operative Society. The
target population was divided into two strata that are senior
xxxv
management level employees and junior employees. These include
the Customer care, credit officers, accountants, branch marketing
managers and branch manager. The reason for selection of the
target population was dueto the convenience, time allowed and
financial resources available to me.
3.3 Sampling Procedures
The target population of the study will be 49 respondents and a
sample size of 15 respondents. Sampling is a procedure of
selecting a part of the population on which research is to be
conducted. It ensures that conclusions from the study can be
generalized to the entire population.I employed stratified random
sampling procedure. Stratified sampling was preferred as it is
suitable to include the elements from each of the categories and
it enabled to divide the population into two strata then get 30%
as representatives from the strata randomly. The strata are made
up of management level employees and junior employees. A 30% is
assumed to be representative of the general population (Mugenda
and Mugenda 2003). It further ensures that the whole population
is represented.

Category Target Sample (30%)

Senior management employees 10 3
Junior Employees 39 12

3.4 Data Collection Procedures
3.4.1 Simple Random Sampling
Simple random sampling involves giving individuals of the
population equal chance of being selected. After categorization
then samples were picked randomly from the stratum by only
considering the 1st, item or/ 5th item or/ and the 9th item and
whoever will be chosen will form the sample.
3.4.2 Stratified Sampling
Stratified sampling method was used because the population is
heterogeneous. I used stratified sampling to achieve desired
random sample from various groups in the population. Under this
technique individuals will be selected in such a way that the
existing sub-groups are more or less represented in the sample.
xxxvii
3.4.3 Data Collection Instruments
For the purpose of collecting the data, questionnaires and
interviews were used.
3. 4.3.1 Questionnaires
Questionnaires assisted in collecting opinions from respondents.
They are useful since the numbers of people from whom the facts
will be collected will be many and the questionnaires will create
uniformity of responses. They are inexpensive, quick and reliable
way of gathering information. This is due to the fact that
individuals can maintain anonymity and therefore, provide real
facts. The questionnaires will be open and closed ended
questions.
3. 4.3.2 Interviews
This involves face to face interaction and discussion. Responses
will be recorded for analysis. The questions that will be asked
are designed to cover issues to do with product diversification
and its effects on performance of SACCOs.
The interview will be guided by the use of structured question.
The questions will be both open and closed ended.
xxxviii
3.5 Validity and Reliability
Validity is the extent to which differences found with a
measuring tool reflect true differences among the sources. The
purpose of validity in the study is to seek relevant evidence
that confirms the answers found with the measurement device which
is the nature of the problem. The validity of the instrument was
ensured through constructive criticism from friends and research
assistant. The items were revised and improved accordingly. On
the other hand reliability is the accuracy and precision of a
measurement procedure. The reliability of the instrument was
improved through pre-testing. Pre-testing involves relying on
colleagues and friends to refine measuring instrument. Validity
and reliability of the instruments was done in order to limit the
distorting effects of random efforts on the findings.
3.6 Data Analysis Procedures
The data collected from several sources for the purpose of the
study will be adopted and reorganized. Data capturing will be
done using Excel sheets. The data from the completed sheets will
be recorded and analyzed using tables and graphs in a summarized
pattern in the response to the study problem.

CHAPTER FOUR
4.0 DATA ANALYSIS, PRESENTATION AND INTERPRETATION
4.1 Background Information
The researcher sought this information to find out the kind of
persons he was dealing with. This information includes gender of
the respondents, educational level and working experience of the
respondents
4.1.1 Gender of the Respondents
The study sought to establish gender of the respondents so as to
establish on the criteria used by the management in its
employment. In most organizations, private, public, profit making
or non-profit making, there has been call to enhance equity and
gender balance in all appointments. The researcher was thus
motivated to determine whether the organization employs or
observes gender balance in its employment. Table 4.1 shows gender
distribution in the organization.
Table 4.2 Gender of the respondents
xl
Gender Frequency Percentages
Male 12 80
Female 3 20
Total 15 100
Source; researcher 2014
The results as shown in the table 4.2 above shows that 20% of the
staff are female and majority of employees representing 80% were
male. This is a clear indication that there is gender inequality
in Marakwet teachers SACCOs and the management should address
this issue of gender imbalance.
4.1.2 Respondent’s Educational Level
This was sought to give the researcher an insight of the level of
education of the employees in the company. In promoting
employees, the level of education is a critical variable that has
to be put into account. There also exists a relationship between
employees’ performance and qualification or level of education.
Also in interpreting the effects of loan portfolio
diversification on organizational performance, the level of
education is critical. This was the reason why the study sought
to determine this information, and it was tabulated as shown inxli
table 4.2 below.
Table 4.2 Respondents Level of Education
Level of Education Frequency Percentage
Secondary 0 0
Diploma 7 47
Degree 3 20
Masters 3 20
Others 2 13
Total 15 100
Source; researcher 2014
From the findings, it was established that majority of the
respondents hold diploma certificates as shown by 47 %, some 20 %
hold masters degree. On the other hand, 20% are first degree
holders and 13% of the respondents hold other qualifications like
CPA, CSIA and CPS. This shows that majority of the employees are
quite educated in the company and understand loan portfolio
diversification.
xlii
4.1.3 Respondents’ Position in the Company
The researcher sought to determine the position employees hold in
the organization. This was vital since it enabled the researcher
to know specific questions to ask to specific group of employees.
The feedback of this item is as indicated in Table 4.3 below.

officers, and other 3 are Customer care staff. These findings
show that the company is fairly balanced in terms of employees in
various departments of positions.
4.1.4 Working Years of Service
Employees with longer period of service are more experienced and
are in a position to explain organizational functions, processes
and activities. Employees with adequate and enough working
experience are in a better position to understand loan portfolio
diversification in the company. The researcher therefore set out
to determine how long the employees had worked in the SACCO. The
findings are presented as shown in the Table

The results in the above table show that 33% of the respondents
have worked in the company for a period of between 1-4 years, 27%
of the respondents have a working experience ranging from 5-9
years, 27% have worked in the company between 10-14 years and the
xliv
remaining 13% have a working experience of over 15 years. These
findings show that majority of the respondents have worked for
relatively long periond in the company and thus are in a better
position to understand loan portfolio diversfication in the
company.

5.5 Suggestions for Further Research
For SACCO, financial sub-sector to grow there is need for the
sector to ensure that it adequately strengthen itself and come up
lix
with solid solutions that can be implemented. Despite the fact
that there are certain self-advanced strategies that can be
adopted by the sub-sector itself, there are also external efforts
that can still be made. This requires further research into the
sector to ensure that the strategies work effectively.There is
also need for further research to identify the effects of
management skills of the SACCO employees on the performance and
the same should be done on the banks.
