ABSTRACT

Corporate diversification is one of the fundamental strategic alternatives

available to organisations to sustain growth and search for greater profits.

International research has been conducted since the 1950’s to establish if

diversification creates value and if it resulted in greater financial performance.

The findings are inconsistent and there remains a lack of consensus regarding

the diversification-performance relationship, although there has been a trend

since the 1990’s of organisations focusing more on their core competencies.

A quantitative research methodology was followed whereby organisations listed

on the industrial sector of the Johannesburg Securities Exchange (JSE) were

categorised as either diversified or focused organisations. Each category

consisted of 15 organisations, against which four financial measures were

compared from the period 2001 to 2005 in the form of hypotheses, to determine

which category of organisations performed better than the other.

Three of the four performance measures are not statistically significant to prove

that either the diversified group or the focused group of organisations

outperformed the other. One of the financial measures is statistically significant

and it was found that the Average Market Return (AMKTRET) of focused

organisations outperform the AMKTRET of diversified organisations.

1. INTRODUCTION TO RESEARCH PROBLEM

1.1 BACKGROUND

Corporate diversification has long been regarded as a strategic tool for

organisations to sustain growth and profitability. Rumelt’s pioneering research in

the 1970’s on United States of America (USA) organisations suggested that

focused organisations performed well, and the success of the book “In search of

Excellence” written by Peters and Waterman in the 1980’s further reinforced the

view that staying focused results in superior performance. However, there is

some evidence that a few organisations that operate a diversified set of

businesses do exceeding well such as Berkshire Hathaway (Bruner, 2003) and

General Electric in the USA.

Internationally, research conducted by Palich, Cardinal and Miller (2000),

concluded that although substantial research has been conducted in the

diversification field in the USA and Western Europe, findings were inconsistent

and that there remains a lack of consensus regarding the diversification-

performance relationship.

In South Africa, there has been no systematic study of the diversification-

performance relationship. The apartheid policies of the past drove South Africa

into economic isolation, forcing many organisations to diversify during the

period from the 1960’s to the early 1990’s. With the integration of South Africa

into the world economy, many organisations divested their non-core assets, and

Page 13: THE IMPACT OF DIVERSIFICATION ON THE FINANCIAL …

2

there is ample evidence that organisations which divested their non-core

businesses and focused on core industries have also done well (Bhana, 2004).

A few diversified organisations however retained their diverse portfolio of

businesses. Notable examples are Bidvest Limited, Barloworld Limited and

Imperial Holdings Limited to mention a few, which seem to have had a

successful track record.

A study of this kind would be of significant benefit to Chief Executive Officers

(CEO’s) and managers in designing their growth strategies.

Diversification is a key strategic decision used as part of an organisation’s

corporate strategy to pursue different markets in anticipation of creating

enhanced returns and ultimately greater profits. This study is an attempt to

answer the key question: Does a high degree of diversification result in greater

financial performance vis-à-vis a focused (low degree) strategy? Within the

resource based view of the picture, Collis and Montgomery (2005) suggest that

an effective diversification strategy can only be conducted if there is a fit

between the resources and the businesses so that the resources contribute in

an important way to competitive advantage.

Gourlay and Seaton (2004) in their research in the UK, argue that firms diversify

for two main reasons. The first reason is in line with the resource based view

that organisations utilize their excess capacity of propriety assets in the

presence of transactional costs. The Organisational specific assets such as

Page 14: THE IMPACT OF DIVERSIFICATION ON THE FINANCIAL …

3

managerial skills, research and development (R&D) and brand reputation

increases the bias towards the diversification decision. The second reason for

diversification relates to governance factors such as the agency problem that

exists between shareholders and management. Gourlay and Seaton (2004)

mentioned that managers have an incentive to diversify as it entrenches the

managers’ positions within the organisation by increasing the demand for their

skills, which is not necessarily to the benefit of the shareholders.

The core focus of this research report relates to the question of whether

diversified organisations deliver superior financial performance than

organisations that choose to operate as a focused organisation. The research

conducted in determining the diversification and performance relationship has

been inconclusive and has been debated since the 1950’s. Piscitello (2004)

noted that the diversification-performance literature has failed to reach

consensus and that there is still considerable disagreement about how and

when diversification can be used to build long term competitive advantage.

1.2 THE RESEARCH PROBLEM

To diversify or not to diversify is one of the key strategic decisions taken by the

CEO, the Board or the Executive team of an organisation. The effectiveness of

diversification as a strategic tool has been mixed and questioned by many

practitioners, as well as by academics. It is unclear if diversification adds value

Page 15: THE IMPACT OF DIVERSIFICATION ON THE FINANCIAL …

4

to an organisation and if it leads to superior financial performance than

organisations that follow a more focused strategy.

Several international studies have been conducted to determine if diversification

leads to superior financial and economic performance, or if it leads to value

destruction. The evidence in different markets, countries and functions are

contradictory. Panday and Rao (1998) suggests that there is a difference in

opinion between functional disciplines within organisations, with Management

and Marketing favouring related diversification on the one hand, while Finance

makes a strong case against corporate diversification. Ushijima and Fukui

(2004) attempted to measure economic performance of diversified companies in

Japan as they wanted to understand why firms refocused in the 1990’s and to

establish what went wrong for Japanese companies. Ramanujam and

Varadarajan (1989) in their attempt to conduct a synthesis concluded that the

literature on diversification covers a great degree of breadth and scope, but that

no comprehensive review of the literature exists.

The research study will attempt to measure the financial performance of a group

of diversified and focused organisations of a sample of companies listed on the

industrial sector of the JSE.

1.3 OBJECTIVE OF THIS RESEARCH

The objective of the research is to provide empirical evidence on the impact of

the level of diversification on the financial performance of organisations that are

Page 16: THE IMPACT OF DIVERSIFICATION ON THE FINANCIAL …

5

listed in the industrial sector of the JSE. The diversified organisations will be

compared against the focused organisations on the industrial sector of the JSE

to ensure that the comparisons are within the same sector. The aim is to

measure and determine if there is a difference in financial performance between

the two categories of organisations from the period 2001 to 2005. The

categorisation would have to be determined over the five year period to ensure

that the organisations remain diversified or focused to be able to measure the

financial performance in a consistent manner.

1.4 SCOPE AND LIMITATIONS OF THIS RESEARCH

1.4.1 Scope

The scope of this research is limited to study two extreme categories of

organisations: Diversified versus Focused organisations.

The research was concerned with the classification of organisations as

diversified versus focused using a categorisation method developed by Rumelt

(1982), as well classifying the organisations’ activities according to their

reported Standard Industrial Classification (SIC) code. The organisations that

were analysed as part of the population had to meet the following criteria:

• The organisations in the sample had to be listed organisations on the JSE

over the five year period from 2001 to 2005.

• The organisations’ annual reports had to be reviewed and SIC codes

assigned to their segmented revenue reporting.

Page 17: THE IMPACT OF DIVERSIFICATION ON THE FINANCIAL …

6

• The identified organisations within the sample had to remain diversified or

focused throughout the five year time period.

• The comparison of the organisations had to be in the industrial sector of

companies trading on the JSE.

• The same financial ratios and adjusted financial data had to be used

throughout the calculation process.

The four financial measurements that were used in the research to calculate the

financial performance of the two groups of diversified versus focused

organisations were measurements previously used in research conducted by

Rumelt (1982) and Panday and Rao (1998).

1.4.2 Potential limitations

The potential limitations of the research report can be summarised as follows:

• Using only two extreme categories of diversified versus focused

organisations. Rumelt (1982) study made use of nine categories.

• Research was limited to the industrial sector due to availability of data and

the manual nature of determining the level of diversification.

• Obtaining accurate information per organisation to calculate the

Specialization Ratio (SR). The SR is a methodology to determine the level of

an organisation’s diversification.

• The annual reports do not clearly classify the segmented revenue reporting

necessary to assign a relevant SIC code to the reported revenue.

Page 18: THE IMPACT OF DIVERSIFICATION ON THE FINANCIAL …

7

• Classification of the companies SIC codes as per the segmentation reporting

could be subjective if the information is not clear enough.

• Analysis of the organisations SIC code is done at the three-digit level which

is at a high level. A more in depth analysis would require the SIC code

analysis to be done at the four-digit SIC code level.

• Only four hypotheses and average measures are used to calculate the

financial performance of the diversified versus the focused organisations.

• The sample size of 15 organisations per category of diversified and focused

organisations is relatively small.

• The lack of South African research material relating to the financial

performance measurement of diversification.

2. LITERATURE REVIEW

2.1 CORPORATE STRATEGY

2.1.1 Definition of corporate strategy

Since the 1950’s, corporate strategy has evolved as a discipline with greater

focus and organisations are constantly investigating ways to create more value.

In formulating a definition of strategy, Porter (1987) divided strategy into two

distinct levels. The first level of strategy is business unit strategy, which is

concerned with strategic decisions within each separate business unit as they

operate and compete as independent units. The second level of strategy is the

company wide or corporate strategy. The corporate strategy is the overarching

strategy that makes the corporate whole add up to more than the sum of the

individual business unit parts.

Collis and Montgomery (2005) define corporate strategy as the way a company

creates value through the configuration and coordination of its multimarket

activities. This research report relates to the topic of diversification which is a

strategic tool within corporate strategy which managers can follow in the quest

to create greater value.

Page 20: THE IMPACT OF DIVERSIFICATION ON THE FINANCIAL …

2.1.2 Generic strategic alternatives available to organisations

Managers have various generic strategic tools and alternatives available to

pursue the organisation’s desired strategy, depending on their objectives.

Ansoff (1958) developed a conceptual matrix whereby an organisation could

pursue growth alternatives as different product-market strategies. The four

business growth alternatives that were available to managers are described in

Table 1 below.

Table 1: Ansoff's business growth alternatives Business Growth Alternative Description

Market Penetration Increase sales without departing from an original product-

market strategy. The business can grow sales by

increasing volume to present customers or finding new

customers.

Market Development Business strategy to adapt the current product line to new

markets.

Product Development Business strategy to retain the present market and

develop the product characteristics which will increase the

performance of the product to the current market.

Diversification Business strategy to simultaneously depart from the

current product line and the present market structure. Source: Ansoff, I. (1958)

Ansoff (1958) argued that a simultaneous pursuit of market penetration, market

development and product development was a sign of a healthy progressive

organisation, but that diversification was different from the other strategies in

that it required new skills, techniques and facilities and would lead to

organisational changes in its structure and functioning.

David (1997) summarized various strategies that organisations can follow into

thirteen actions as described in Table 2.

Page 22: THE IMPACT OF DIVERSIFICATION ON THE FINANCIAL …

11

From a corporate strategy point of view, De Wit and Meyer (2004) argue that

corporate strategy is about selecting an optimal set of businesses and

determining how they should be integrated as a whole. The process of deciding

the best array of businesses and relating them to one another is referred to as

corporate configuration. In determining the configuration of the organisation two

questions can be asked:

1. What business areas should the organisation operate in?

2. How should the group of businesses be managed?

The first question relates to the direction and level of diversification and the

second question relates to management of such an organisation.

This research report will focus on diversification as one of the corporate strategy

alternatives available to organisations.

2.2 DIVERSIFICATION AS A STRATEGIC ALTERNATIVE

2.2.1 Definition of diversification

In researching diversification, it is important to define diversification as a

concept and offer various definitions of diversification. Diversification as a

corporate strategy choice has been suggested as an alternative to foster

continuous growth and change. One of the pioneers of diversification, Ansoff

(1957) defined diversification in terms of a particular kind of change in the

product-market makeup of an organisation. Extending Ansoff’s definition, Aaker

(2001) defined diversification as the strategy of entering product markets

different from those in which a firm is currently engaged. Ansoff (1957)

Page 23: THE IMPACT OF DIVERSIFICATION ON THE FINANCIAL …

12

suggested that diversification is more difficult than other strategies such as

market development and product development, as diversification requires new

skills, new techniques and organisational changes in the structure of the firm.

Diversification is usually driven by the desire (or financial ability) to expand

beyond the apparent limits of existing markets, and / or by the desire to reduce

business risk by developing new “legs” (Koch, 1995).

Ramanujam and Varadarajan (1989) defined diversification as the entry of a

firm or business unit into new lines of activity, either by processes of internal

business development or acquisition, which entail changes in its administrative

structure, systems and other management processes.

2.2.2 Reasons for diversification

Hill and Jones (1998) suggest that companies consider diversification when

they generate financial resources in excess of the funding required to maintain

a competitive advantage in their core business. They argue that a diversified

company can create value in three ways:

• Acquiring and restructuring: The focus of the acquisition is to

purchase a company that is poorly managed and increase efficiencies

through the management expertise of the acquirer. The approach is

considered a form of diversification as the acquirer does not have to be

in the same industry as the acquired company.

Page 24: THE IMPACT OF DIVERSIFICATION ON THE FINANCIAL …

13

• Transferring Competencies: This approach is achieved by the

company transferring key competencies in one of their value creation

functions such as manufacturing, marketing or R&D to a new business to

improve the competitive advantage of the new business.

• Realising economies of scope: This approach applies when two or

more business units share resources such as Research and

Development and advertising. Each business unit that shares resources

has to invest less in the shared function.

Haberberg and Rieple (2001) identified six reasons as to why organisations

might want to diversify:

• Seek growth and capture value added opportunities: Organisations

might perceive opportunities for growth that are not available in their core

businesses and by diversifying into other businesses, they could capture

value and profits for the organisation.

• Spread risk: Organisations might want to spread their risk and diversify

into different businesses as a hedge.

• Prevent competitors from gaining ground: From a defensive point of

view, organisations might want to diversify into other businesses to

prevent their competitors from gaining a foothold in a specific market.

• Achieve synergy: In achieving synergy, the organisation would want to

coordinate some functions by sharing the value chain. Activities such as

purchasing and production across business units could lead to

economies of scale and scope.

Page 25: THE IMPACT OF DIVERSIFICATION ON THE FINANCIAL …

14

• Control the supply and distribution channel: Organisations might

want to diversify to gain control either by backward or forward integration

therefore influencing prices and the supply of raw materials to the entire

organisation.

• The fulfillment of personal ambition by senior management:

Managers might be rewarded for the size of the organisation rather than

the financial performance, thus leading to behaviour of management

seeking diversification as the ultimate strategy.

Incentives also exist externally and internally for a company to follow a

diversification strategy. Hitt, Ireland and Hoskisson (1999) suggest that there

are several reasons for companies to diversify that are value neutral and that

there are several incentives for managers to do so. Table 3 below summarizes

the internal and external incentives of diversification.

Table 3: Internal and external incentives for diversification

Internal Incentives External Incentives

Low Performance: Companies that have had poor

performance over a prolonged period of

time might be willing to take greater risks in

an attempt to improve performance,

thereby diversifying into new businesses.

Antitrust Regulation: Regulation either promoting or inhibiting

diversification plays a role. The regulation

could encourage either diversification in

unrelated businesses due to the strict

regulation to encourage competition and thus

avoid monopolisation, or the regulation might

be more conducive to take-overs and mergers

within the same industries.

Uncertain future cash flows: Companies operating in mature industries

might find it necessary to diversify as a

Tax Laws: Tax laws could encourage companies to rather

reinvest funds as opposed to distribute the

15

defensive strategy to survive over the long

term.

funds to shareholders. Higher personal taxes

encourage shareholders to want the

companies to retain the dividends and use the

cash to acquire new businesses as opposed to

distribution to shareholders.

Risk Reduction: Companies that have synergy between

business units face greater risk as the

interdependencies between the business

units increase the risk of corporate failure.

Diversification could reduce the

interdependency and hence reduce the

risk.

2.2.3 Diversification reasons in South Africa

From a South African perspective, diversification has had a different element

due to the political anomaly that occurred during apartheid. Whereas the

traditional reasons for diversification would have applied to South African

organisations, the political isolation led to an inward focused economy.

According to Rossouw (1997) the South African economy was dominated by six

large conglomerates which accounted for 80% of the JSE market capitalization

in the 1970’s and 1980’s. The reasons for the high degree of capitalization by

the six conglomerates was the fact that the South African government

prohibited South African companies from foreign investment, and strict

exchange controls prohibited the organisations from investing offshore. The

regulation and the sanctions that were placed on South African organisations

Page 27: THE IMPACT OF DIVERSIFICATION ON THE FINANCIAL …

16

compelled South African organisations to invest and diversify by acquiring local

companies which led to the formation of large diversified conglomerates.

2.3 DIVERSIFICATION TRENDS

As the economic outcome of diversification has been mixed since the early

1900’s, various phases and trends have occurred. In a study conducted by

Chandler (1969), the changing industrial structure of the USA economy was

researched where the concentration of organisations was measured per decade

from 1909 to 1963. In Chandler’s study a concentrated industry was defined

where six or fewer organisations contributed to fifty percent, or twelve or fewer

organisations contributed to 75%of the total product value.

Chandler’s (1969) research had the following findings:

• Concentration tended to increase through World War II and declined slightly

thereafter.

• The depression of the 1920’s forced organisations into diversification,

especially chemical companies and electrical manufacturers such as

General Electric and Westinghouse.

• World War II encouraged organisations to adopt diversification by opening

new opportunities for the production of new products such as radar

equipment and other war products.

Page 28: THE IMPACT OF DIVERSIFICATION ON THE FINANCIAL …

17

• The post World War II boom was characterized by constrained demand and

the rapid expansion of government spending on R&D which gave

momentum to diversification in the 1940’s and 1950’s.

• Diversification was primarily in those industries which made use of

sophisticated scientific techniques in modern chemistry and physics.

• In 1947 the largest 200 organisations accounted for 30% of the value added

by manufacturing, and by 1963 the figure rose to 41%.

• By the 1960’s organisations developed the decentralized organisational

structure which was fashioned by the DuPont Corporation. The

decentralized structure was developed as an effective administrative

process to be able to lever the autonomous operating divisions of an

organisation and as a result institutionalized the strategy of diversification.

Chandler’s (1969) research thus indicated a steady increase in organisations

diversifying from the early 1900’s to the 1960’s due to the various reasons listed

above.

During the 1970’s the concept of portfolio planning was developed in response

to the problem and prospects of managing sustainable growth. This became the

primary tool for resource allocation in organisations and represented an

analytical breakthrough in corporate strategy and diversification (Collis and

Montgomery, 2005). In research conducted by Haspeslagh (1982), portfolio

planning philosophy would have taken place in three steps within an

organisation:

Page 29: THE IMPACT OF DIVERSIFICATION ON THE FINANCIAL …

18

• Redefine the business as Strategic Business Units (SBU’s) which may or

may not differ from operating units.

• Classification of SBU’s on a portfolio grid according to the competitive

position and attractiveness of the particular product market.

• Allocate resources to the SBU’s in terms of the growth and financial

objectives.

According to Haspeslagh (1982) the above portfolio planning process was a

mechanism for managers to determine each SBU’s position within an industry

and allocate resources to those SBU’s for differentiating strategic influences

and to best manage diversification. Haspeslagh (1982) further concluded that

by 1979, 45% of the Fortune 500 industrial companies had introduced the

portfolio planning process to some extent and that it had been increasingly

introduced.

According to Collis and Montgomery (2005) the portfolio planning process was

not sustainable as it assumed that organisations needed to be internally self-

financed, while in practice there was no rationale for such a policy when the

capital markets were efficient. The 1980’s saw the failure of diversification

strategies in the USA, and a new drive for organisations to focus on their core

competence.

Berger and Ofek (1995) mentioned that during the 1950’s and 1960’s massive

diversification programs were undertaken with the climax being reached in the

Page 30: THE IMPACT OF DIVERSIFICATION ON THE FINANCIAL …

19

USA in the late 1960’s. The last 25 years have seen a reversal of the

diversification strategy whereby many firms in the USA were refocusing on their

core business. A similar study was conducted by Ushijima and Fukui (2004)

which showed that many Japanese organisations reversed the diversification

strategy to focus on their core business. Koch (1995) phrases this term as

“sticking to the knitting.”

Turner (2005) summarized the history of diversification into three phases:

• 1960’s and 1970’s: The period was well known as an era when

diversification was fashionable as a remedy to companies that were

faced with maturity in their core businesses.

• 1980’s: Companies were urged to sell non-core businesses and to focus

on much smaller, more manageable portfolio businesses and to occupy

dominant market positions.

• 1990’s onwards: Companies were refocusing and were not diversifying

to the extent as in the 1960’s and 1970’s. The trend, however, was to

pursue international diversification (compared to product diversification)

which has been increasing in importance and has led to greater financial

performance relative to product diversification.

Although the phases of diversification studies were mainly conducted in the

USA, Hitt et al. (1999) remarks that although the trends are more significant in

the USA, Europe, Asia and other industrialized countries have followed similar

trends.

Page 31: THE IMPACT OF DIVERSIFICATION ON THE FINANCIAL …

20

2.3.1 Diversification trends in South Africa

Due to the economic sanctions and regulation placed on South African

organisations, many South African organisations were obliged to invest within

South Africa which led to the formation of large diversified conglomerates in the

1970’s and 1980’s (Rossouw, 1997), resulting in a trend of increased

diversification.

Since the early 1990’s, according to research conducted by Bhana (2004) there

had been a decline in the amount of mergers, acquisitions and other forms of

expansions, and many conglomerates downsized and focused their businesses

on their core competencies. Bhana (2004, p. 5) researched the performance of

corporate restructuring through spin-offs on the JSE, and defined a spin-off as

“When an organisation distributes shares of a subsidiary to its shareholders.

The primary effect is that the subsidiary becomes a separate decision-making

organisation with separation of control from the parent organisations

management”.

Bhana’s (2004) study identified a total of 47 voluntary spin-offs that were

initiated by 19 parent organisations during the period 1988 to 1999, which was

an indication that South African organisations were following the same trend as

other countries by focusing on their core competencies.

2.4 ENTRY STRATEGIES FOR DIVERSIFICATION

Various diversification entry strategies exist for organisations to pursue. Aaker

(2001) suggested that diversification strategies could be accomplished through

various entry strategies such as internal development, acquisitions, joint

ventures, licensing agreements and alliances. The various entry strategies have

certain advantages and disadvantages which organisations have to consider.

Some of the entry strategies available to organisations are summarized in

Table 4 below.

Table 4: Entry Strategies for organisations

Entry Strategy Advantages Disadvantages

Internal Development • Uses existing resources

• No acquisition costs

• Time lag

• Uncertain prospects

Internal Venture • Uses existing resources

• May keep talented

entrepreneurs

• Mixed success record

• Can create internal stress

operations between

companies

• Value of one company may

be reduced over time

Licensing from others • Rapid access to technology

• Reduced financial risk

• Lack of propriety technology

and technological skills

• Dependent on licensor

Educational Acquisition • Provides window and initial

staff

• Risk of departure of

entrepreneurs

Licensing to others • Rapid access to a market

• Low cost/risk

• Will lack knowledge/control of

market

• Dependent on license Source: Aaker, D. (2001)

Page 33: THE IMPACT OF DIVERSIFICATION ON THE FINANCIAL …

22

Although an organisation has a wide variety of entry strategies available, Collis

and Montgomery (2005) suggests that choosing among the various models

involves unavoidable trade-offs that need to be carefully analysed.

2.5 DIVERSIFICATIONS IMPACT ON AN ORGANISATION’S

FINANCIAL PERFORMANCE

2.5.1 Background

The core focus of this research report relates to the question of whether

diversified organisations achieve superior financial results than organisations

that choose to operate as a focused organisation. The research conducted in

determining the diversification and performance relationship has been

inconclusive and has been debated since the 1950’s. Piscitello (2004) noted

that the diversification-performance literature has failed to reach consensus and

that there is still considerable disagreement about how and when diversification

can be used to build long-term competitive advantage.

In conducting research in the diversification versus performance debate, there

are three aspects that are commonly found in the literature that will be focused

on and will be expanded on in the sections below:

• The two primary approaches in determining the level of an organisation’s

diversification are examined. The two primary approaches are the

categorisation approach, and the product count measure approach.

Page 34: THE IMPACT OF DIVERSIFICATION ON THE FINANCIAL …

23

• The performance measures used to determine the organisation’s

performance are examined. The two primary measures are accounting and

market based approaches.

• The findings of some of the research as either being supportive of the

statement that diversified organisations have a positive relationship or

negative relationship to their economic performance are examined.

The three aspects are important, as they form the core of the research

conducted in the literature and are interrelated. The research would be

conducted by first grouping the organisations as diversified versus focused,

determining the performance measurements to be used in the hypotheses,

resulting in the overall findings of the research.

Other research findings are also presented that are either conceptual or

empirical that do not follow the same methodology as presented above.

2.5.2 Determining the level of an organisation’s diversification

The first aspect in the literature relating to the diversification versus

performance debate relates to the approaches used to establish the level of an

organisation’s diversification. In the literature there are two primary approaches

used to determine the level of an organisation’s diversification.

The first approach was pioneered by researchers such as Rumelt (1982) who

developed a categorisation approach whereby organisations were categorised

Page 35: THE IMPACT OF DIVERSIFICATION ON THE FINANCIAL …

24

into various categories based on measurements obtained from financial data,

financial data base information and Standard Industrial Classification (SIC) code

descriptions. The second approach is referred to as the product count measure,

whereby an organisation’s SIC code is used to determine the organisation’s

primary activity, and therefore the business segments the organisation operates

in. The two approaches will be discussed in more detail below, and in her

research to compare the use of the two approaches, Montgomery (1982) found

that neither approach is superior to the other.

2.5.2.1 Rumelt’s categorisation model

The first approach developed by Rumelt (1982) contains various categories of

diversification which were classified utilising ratios of revenues earned as a

fraction of the total revenues earned within the total revenue of an organisation.

Table 5 summarizes the major categories Rumelt developed to study the

financial performance of organisations and the degree of diversification. In

Rumelt’s scheme, the least diversified (Single Business) is on the one side of

the scale and the most diversified (Unrelated Business) is on the other side of

the diversification scale. The various ratios of importance that Rumelt used to

measure the revenues earned as a fraction of total revenues earned were:

• Specialization Ratio (SR): This ratio measures the proportion of an

organisation’s revenues derived from its largest single business.

• Related Ratio (RR): This ratio measures the proportion of an organisation‘s

revenues derived from its largest single group of related businesses.

Page 36: THE IMPACT OF DIVERSIFICATION ON THE FINANCIAL …

25

Table 5: Rumelt's major categories of diversification

Dominant Business Companies that have diversified to some

extent but still obtain the predominance of

their revenues from a single business

(SR between 0.7 and 0.95)

Related Business Nonvertical dominant companies that

dominant activity

SR < 0.7

Unrelated Business Nonvertical companies that have chiefly

diversified without regard to relationships

between new businesses and current

activities

RR < 0.7

Source: Rumelt, R. (1982)

Rumelt (1986) calculated the SR in first identifying the businesses the

organisation operated in. The activity breakdown information was obtained via

the four-digit SIC code classification over the period of study. Secondarily to the

segment breakdown via the four-digit SIC code, financial data per segment was

obtained per organisation via databases and the organisation’s prospectuses in

order to calculate the SR and RR.

Rumelt (1986) developed a further categorization of the diversification

strategies into subcategories. Table 6 below indicates the further breakdown

and definition of the subcategories Rumelt used in his research.

Table 6: Rumelt’s subcategories of diversification Category Definition

1-Single Business Organisation committed to a single business

2-Dominant Vertical Vertically integrated organisations that produce and

sell a variety of end products, no one of which

Page 37: THE IMPACT OF DIVERSIFICATION ON THE FINANCIAL …

26

contributes more tan 95% of total revenues.

3-Dominant Constrained Nonvertical dominant organisations that have

diversified by building on some particular strength

with the original dominant activity.

4-Dominant Linked Nonvertical dominant organisations that has

diversified by building on new strengths, skills, or

resources as they are acquired.

5-Dominant Unrelated Nonvertical dominant organisations in which the

prevalence of the diversified activities are unrelated

to the dominant business.

6-Related Constrained Related organisations that has diversified by

relating new businesses to a specific central skill or

resource and in which each business activity is

related to almost all of the other business activities.

7-Related Linked Related organisations that have diversified by

relating new businesses to some strength or skill

already possessed, but not always the same

strength or skill. These organisations diversify in

several directions and become active in a widely

disparate business.

8-Unrelated Passive Unrelated organisations that do not qualify as

acquisitive conglomerates.

9-Acquisitive

Conglomerates

Nonvertical organisations that have aggressive

programs for the acquisition of new unrelated

businesses. Source: Rumelt, R. (1986)

The term diversification has various meanings to various individuals or

organisations, and from Rumelt’s (1982) classification and other literature, the

two primary diversification types that are most referred to are related

diversification and unrelated diversification. Related diversification is defined by

Hill (1994) as realising economies of scope in the sharing of resources and / or

the transfer of skills between two or more otherwise distinct businesses within

an organisation. Unrelated diversification is defined by Rumelt (1986) as firms

Page 38: THE IMPACT OF DIVERSIFICATION ON THE FINANCIAL …

27

that diversify into areas not related to the original skills and strengths, other than

financial resources.

Rumelt’s (1982) classification has been used and modified by numerous other

researchers such as Panday and Rao (1998), Markides (1995) and Harper and

Viguerie (2002). Research conducted by Panday and Rao (1998) in the USA

used Rumelt’s classification schemes, but adjusted the SR values for their

purposes to focus on three of the categories. Panday and Rao (1998) utilized a

Compustat database to calculate the various organisations SR, whereby the

organisations were classified into their modified scheme which is summarized in

Table 7 below.

Table 7: Panday and Rao's SR classification Category Rumelt’s SR values Panday and Rao’s SR values

Single Business SR ≥ 0.95 SR ≥ 0.95

Dominant Business

(Moderately diversified

organisation)

0.7 < SR < 0.95

0.5 < SR < 0.95

(SR between 0.5 and 0.95)

Related Business

(Highly diversified

organisation)

SR < 0.7 SR < 0.5

Source: Pandaya, A. and Rao, N. (1998)

Panday and Rao (1998) argued that the adjustment of the SR from 0.7 to 0.5

was to address the contradictory arguments advanced by researchers in

finance and management disciplines.

Page 39: THE IMPACT OF DIVERSIFICATION ON THE FINANCIAL …

28

Similar to Panday and Rao (1998), Harper and Viguerie (2002) modified the

categories in their Mckinsey Quarterly research whereby they classified 412 of

the Standard & Poors 500 (S&P 500) companies from the period 1990 to 2000.

Harper and Viguerie’s (2002) classification can be summarized as follows:

• Focused Organisations: Deriving at least 67% of revenues from one

business segment.

• Moderate Diversification: Deriving at least 67% of revenues from two

business segments.

• Diversified Organisations: Deriving less than 67% of revenues from two

business segments.

Harper and Viguerie (2002) argued that the cutoff point of 67% was not chosen

empirically, but that they were confident that the results would be the same

even if the cutoff varied within 10 percentage points in either direction.

Research conducted by Markides (1995) to establish refocusing efforts in the

1980’s, used Rumelt’s (1982) original categorisation classification as one of the

approaches to measure the refocusing efforts of firms during the time period of

1981 to 1987.

In research conducted by Sambharya (2000) to compare the approaches

available to researchers in the measurement of corporate diversity, he noted

various strengths and weaknesses of using Rumelt’s classification as an

approach to measure the level of diversity of an organisation.

Page 40: THE IMPACT OF DIVERSIFICATION ON THE FINANCIAL …

29

Sambhaya (2000) noted the following advantages:

• Conceptual rigour. The researcher would rely on the insight in the

organisations history and behaviour to determine its utilisation of strength,

core skills and its diversification objectives.

Sambhaya (2000) noted the following disadvantages:

• The classification is subjective, and the reliability is questionable.

• The classification process is time consuming and requires extensive

information on the organisations from various sources.

The research report will focus on categorizing companies as either diversified or

focused using Rumelt’s (1982) Specialization Ratio (SR) in conjunction with the

product count measure.

2.5.2.2 Product Count Measures (Standard Industrial Classification)

The second approach used by researchers is the product count measure which

was built on the Standard Industrial Classification (SIC) system developed in

the USA. Montgomery (1982) defines the SIC classification as a numerical

system developed by the USA Federal Government for classifying all types of

economic activity within the USA economy. Each firm’s activity is classified

according to its primary activity. As Harper and Viguerie (2002) remarked that

publicly USA listed organisations have to report segmented revenues by a

Financial Accounting Standards Board (FASB) segmentation scheme.

Page 41: THE IMPACT OF DIVERSIFICATION ON THE FINANCIAL …

30

Although the SIC classification was developed in the USA, the SIC system has

been adopted throughout the world and has become an internationally accepted

classification mechanism of all economic activities. According to the South

African Companies and the Intellectual Property Registration Office (CIPRO)

(2006), the SIC was developed for the classification of the kind of economic

activity and provides a standardised framework for the collection and analysis of

statistical data. See Appendix 1 for an extract of some of the SIC codes

obtained from CIPRO.

The SIC classification consists of a five digit number that has the following

meaning and filters down to more deeper levels of economic activity as

indicated in Table 8 below:

First Digit Major Division

Second Digit Division

Third Digit Major Group

Fourth Digit Group

Fifth Digit Sub-Group Source: South African Companies and Intellectual Property Registration Office (CIPRO)

http://www.cipro.co.za/info_library/sic_codes.asp

If for example the SIC code was 35592, the following meaning can be derived

from the SIC code in Table 9 below:

Page 42: THE IMPACT OF DIVERSIFICATION ON THE FINANCIAL …

Fifth Digit 2 Sub-Group Manufacture of cables and wire products Source: South African Companies and Intellectual Property Registration Office (CIPRO)

http://www.cipro.co.za/info_library/sic_codes.asp

Researchers such as Rumelt (1986), Berger and Ofek (1995), Delios and

Beamish (1999) and Ushijima and Fukui (2004) used the SIC code approach to

measure the level of diversification in their studies.

Berger and Ofek (1995) researched diversification’s effect on firms’ value, and

utilised the SIC code approach to classify the diversification levels of the

organisations in their samples from 1986 to 1991. In the USA, organisations are

required to report segmented information where sales or profits exceed 10% of

the consolidated totals. From the segmented reporting, the SIC code

information was obtained.

In Delios and Beamish (1999) research, the diversification levels of 399

Japanese manufacturing organisations were tested. The source of information

Page 43: THE IMPACT OF DIVERSIFICATION ON THE FINANCIAL …

32

in their study was the Japanese Company Handbook to determine the

industries in which the organisations operated. Delios and Beamish (1999) used

the three-digit SIC level to classify the diversification levels, but would have

preferred to use the four-digit SIC code classification level. Due to limitations on

industry details and source information, the three-digit SIC code level was

utilised. In a similar study Ushijima and Fukui (2004) studied 118 Japanese

manufacturing organisations from 1973 to 1998. During their study the

organisations’ sales were segmented by product into SIC codes, whereby

analysis was done at the four-digit SIC code level.

In research conducted by Sambharya (2000) to compare the approaches

available to researchers in the measurement of corporate diversity, he noted

various strengths and weaknesses of using the product-count approach (SIC) to

measure the level of diversity of an organisation.

Sambhaya (2000) noted the following advantages:

• Simplicity and ease of measurement and computation.

Sambhaya (2000) noted the following disadvantage:

• Validity and reliability is questioned.

2.5.2.3 Combination of both approaches

Research conducted by Montgomery (1982) in the use of both the

categorisation and the product count approach (SIC code), concluded that there

are strengths and weaknesses in both approaches. In her findings she found

Page 44: THE IMPACT OF DIVERSIFICATION ON THE FINANCIAL …

33

that the SIC code approach was more acceptable than previous criticism would

indicate, and that at the two-digit, three-digit and four-digit SIC code level

analysis was favourable. In her findings she also concluded that neither

approach is superior to the other.

Research conducted by Rumelt (1986), Markides (1995) and Harper and

Viguerie (2002) used both approaches to measure the level of diversification of

the organisations in their studies. Markides (1995) used Rumelt’s classification

in his sample of 200 organisations from 1981 to 1987 as well as the SIC code

approach. Markides (1995) made use of a USA database called Trinet and

measured the level of diversification up to the two-digit SIC code level.

Harper and Viguerie (2002) used their modified categorisation as indicated

above, as well as the SIC code analysis. In their research they found that the

organisations that formed part of their classification system were similar to the

organisations that were identified using the SIC code approach.

2.5.3 The performance measures used in research

The second aspect that relates to the diversification-performance literature is

the use of performance measures. In the literature, various researchers made

use of different performance measures, although the most common

performance measures used were Return on Equity (ROE) and Return on

Assets (ROA).

Page 45: THE IMPACT OF DIVERSIFICATION ON THE FINANCIAL …

34

Varadarajan and Ramanujam (1987) researched diversification and

performance and used four performance measures in their study. They

mentioned that the four measures they used were consistent with previous

studies and that their work would be comparable to previous studies conducted.

The four performance measures used and calculated using a five year average

by Varadarajan and Ramanujam (1987) were:

• Profitability Measures

o Return on Equity (ROE)

o Return on Capital (ROC)

• Growth Measures

o Sales Growth Rate (SRG)

o Earnings per share Growth Rate (EPSGR)

Research conducted by Panday and Rao (1998) focused on accounting

variables and a market variable during their study of 2 637 US firms during the

period 1984 to 1990. The performance measures used by Panday and Rao

(1998) were as follows:

• Accounting Variables

o Return on Equity (ROE)

o Return on Assets (ROA)

• Market Variable

o Market Return (MKTRET)

The three performance measures were averaged over the period of study per

diversification category to calculate an Average Return on Equity (AROE), an

Page 46: THE IMPACT OF DIVERSIFICATION ON THE FINANCIAL …

35

Average Return on Assets (AROA) and an Average Market Return (AMKTRET)

per category, to be able to identify if the one category of organisations

performed better than the other.

According to Hall and Lee (1999), past empirical studies on diversification made

use of accounting-based performance such as Return on Assets (ROA) and

Return on Equity (ROE), but more focus is being given to market-based

performance measures such as Market Value of Equity (MVE) and Market

Value of Assets (MVA).

Table 10 below is a summary of some of the performance measures that were

used by a variety of researchers in their studies to determine the diversification-

performance relationship:

Rumelt’s (1986) study was conducted

on a sample of 246 organisations in

the USA. The population was the 500

largest industrial corporations.

Rumelt (1986) measured the

performance of the 246 organisations

over the period from 1951 to 1970.

The strategic categorisation was

conducted at three points in time:

1949, 1959 and 1969 and the annual

financial measures were averaged

per decade, and then further

averaged over the entire period from

1951 to 1970.

The performance measures used in previous research as indicated above were

used in this research report to ensure consistency in performance

measurements.

2.5.4 Results of financial performance of diversified companies

The third aspect relating to research conducted in the diversification-

performance debate was the outcome of the results. Many studies have been

conducted internationally to establish if diversification has led to an increase in

a firm’s economic performance. The various studies have resulted in different

outcomes. Palich et al. (2000) noted that there has been inconsistency in the

findings of the diversification-performance research for more than 30 years and

that there is a lack of consensus. Some of the empirical findings were either a

positive relationship to economic performance (e.g., Panday and Rao, 1998:

Singh, Mathur, Gleason and Etebari 2001; and Piscetello, 2004), a negative

relationship with economic performance (e.g., Markides, 1995; Lins and

Servaes, 2002 and Gary, 2005), a curvature relationship depending on the level

of diversification (e.g., Varadarajan and Ramanujam, 1987; Hitt et al.,1999 and

Palich et al. 2000) or a result that depends on the various levels and types of

diversification (Rumelt, 1986).

2.5.4.1 Diversification has a positive relationship with an organisation’s

financial performance

Researchers such as Panday and Rao (1998), Singh et al. (2001) and

Piscetello (2004) and others have found that the relationship between the level

Page 49: THE IMPACT OF DIVERSIFICATION ON THE FINANCIAL …

38

of diversification and the financial performance of an organisation is positively

related.

Panday and Rao’s (1998) study concluded that, on average, diversified firms

showed superior performance compared to focused firms on both risk and

return dimensions. Their study made use of accounting and market return ratios

to measure the performance. In a study conducted by Singh et al. (2001)

utilising a sample of 1 528 firms from 1990 to 1996, they found that diversified

firms performed better than focused firms. The reasons for their results were

that diversified firms improved their leverage, and had a nominal decline in

operating performance, whereas focused firms reduced their leverage and had

a superior operating performance.

In a study conducted by Piscetello (2004) to measure corporate diversification,

coherence and economic performance over the period 1987 to 1993, it was

found that there was a positive relationship between corporate diversification,

coherence and financial performance. The study was conducted using a sample

of 248 industrial organisations of which 109 were USA organisations, 86

European organisations and 53 were Japanese organisations.

Page 50: THE IMPACT OF DIVERSIFICATION ON THE FINANCIAL …

39

2.5.4.2 Diversification has a negative relationship with an organisation’s

financial performance

Researchers such as Markides (1995), Lins and Servaes (2002) and Gary

(2005) and other researchers have found a negative relationship between the

level of diversification and the economic performance of an organisation.

Studies conducted by Markides (1995) suggested a negative relationship

between diversification and the organisation’s average profitability, but did not

necessarily imply that diversified organisations were not maximizing profits, only

that their marginal returns decreased as they diversify further. The

measurements were applied utilising profitability ratios, debt ratios and capital

expenditure ratios.

Delios and Beamish’s (1999) research tested the performance of 399 Japanese

manufacturing firms. The nature of the study focused on accounting ratios to

measure performance, and applied the SIC code approach to determine the

diversification categories. They found that performance was not related to the

extent of product diversification, although investments levels in rent-generating,

propriety assets were related to the extent of product diversification.

In a study conducted by Gary (2005) to determine strategy and performance

outcomes in related diversification, found that a higher degree of relatedness

could intensify resource overstretching in an organisation, which caused lower

profitability compared to an organisation which was less related. He argued that

Page 51: THE IMPACT OF DIVERSIFICATION ON THE FINANCIAL …

40

the potential costs of increased relatedness could outweigh the benefits

created. The measurements were applied in developing and modeling cost

structures of organisations that included the fixed costs, costs of shared

resources and variable costs of servicing new business customers.

Berger and Ofek (1995) calculated that on average, diversified organisations

had a value loss of between 13% and 15% of the 3 659 organisations that were

studied in the USA during 1986 and 1991. They measured the excess value of

the diversified organisations as the natural logarithm of the ratio of an

organisation’s actual value to its imputed value. An organisation’s imputed value

was defined as the sum total of imputed segment’s, with each segment’s

imputed value equal to the segments’ assets, sales or earnings before interest

and tax (EBIT), multiplied by its industry median ratio of capital to that

accounting item.

Similar findings were reported by Lins and Servaes (2002), who measured

corporate diversification in emerging markets from a sample of over 1 000 firms

in 1995, and found that diversified firms traded at a discount of approximately

7% compared to focused firms, and that diversified firms were less profitable

than focused firms. The method to determine the results were a valuation

approach whereby the median market-to-sales ratios were used to compare

with the individual organisation segmented level of sales.

2.5.4.3 Diversification has a curvilinear relationship with an organisation’s

financial performance

Research conducted by Palich et al. (2000) noted that the curvilinear

relationship between corporate diversification and financial performance

(measured as accounting data) suggested that benefits accrue to diversification,

but at some point the efforts of diversification are associated with major costs.

The research was supported by Varadarajan and Ramanujam (1987), using

accounting ratios, which found that related diversified organisations

outperformed unrelated diversified organisations, and that the performance

between extremely low levels and extremely high levels of diversity was

generally insignificant.

Hitt et al. (1999) illustrates that a curvilinear relationship exists between

diversification and performance. An increased level of diversification at a point

where a company diversifies at a related constrained level, leads to an

increased level of performance. Levels of performance reduce, however, when

companies diversify at high levels in unrelated businesses. Figure 1 below

illustrates the curvilinear relationship between diversification and performance.

2.5.4.4 Other research studies relating to diversification

Other research findings are also presented that are either conceptual or

empirical that do not necessarily follow the same methodology as presented

above.

2.5.4.4.1 Ansoff Ansoff (1958) in his conceptual planning framework for diversification suggested

that there could be a multiple variety of tests that could be used to measure the

value of the proposed diversification on the organisation. He concluded that the

most common single test was in the form of Return on Investment, and his

model was one of successive elimination of alternatives involving the

Level of Diversification

43

application of qualitative criteria, followed by a mathematical comparison of

potential profit earned before and after a diversification scenario has been

developed for an organisation. Ansoff (1958) argued that in order to asses the

full effect of diversification, an organisation would have to calculate an average

return over a period which included the transition to diversify the operations.

Only if the potential profit is greater than the cost should a diversified strategy

be considered.

2.5.4.4.2 Rumelt’s study

Rumelt’s studies are regarded as one of the most influential and widely

investigated typologies in the strategy literature (Hall and St. John, 1994). The

findings of Rumelt’s (1986) empirical study conducted on a sample of 246

organisations over a period of two decades from 1949 to 1969 are summarized

below:

• Performance differences existed between the major categories of

diversification strategy (Single, dominant, related and unrelated businesses).

The differences were however highlighted in more detail once the categories

were broken down into subcategories.

• The Dominant Vertical organisations were low performing while the

Dominant Constrained organisations were among the highest performing.

• The Related Constrained subgroup was high performing while the Related

Linked subgroup was slightly below average.

Page 55: THE IMPACT OF DIVERSIFICATION ON THE FINANCIAL …

44

• The Dominant Constrained and the Related Constrained subgroups were

the best overall performers and both strategies were not totally dependent

upon a single business or a true multi-industry organisation.

2.5.4.4.3 Porter’s study Porter (1987) studied the diversification record of 33 large US companies over a

period from 1950 to 1986. Unlike other researchers using financial data and

shareholder value, Porter (1987) conducted an empirical study in which he used

the number of units retained by the company over the period of 26 years as an

indication of the success of the organisations in terms of their diversification.

Porter’s (1987) study is summarized below:

• Each organisation entered on average 80 new industries and 27 new fields.

• Just over 70% of the new entries were acquisitions of which 22% were start-

ups and 8% were joint ventures.

• On average the organisations divested more than half their acquisitions and

more than 60% of their acquisitions in entirely new fields.

• Fourteen organisations divested more than 70% of all the acquisitions they

made in the new fields.

In Porter’s view, only the investment bankers, lawyers and the original sellers of

the businesses prospered in most of the acquisitions. Porter further concluded

that diversification did not add value due to the following reasons:

Page 56: THE IMPACT OF DIVERSIFICATION ON THE FINANCIAL …

45

• Competition occurs at the business unit level and not as a diversified

organisation.

• Diversification adds costs and constraints to business units, such as

corporate overheads and bureaucracy.

Porter (1987) argued that certain conditions need to be met in order for

diversification to create shareholder value and are called the essential test. The

three questions that need to be answered are:

• How attractive is the industry? Diversification cannot create shareholder

value unless new industries have favourable structures that support returns

in excess of the cost of capital, and an industry needs to be attractive before

diversification commences. After the diversification has taken place, only

then can the industry’s structure be transformed.

• What is the cost of entry? Organisations strive to enter the market through

acquisition or start-up, and organisations could end up paying more than

market value for an acquisition. Organisations should do proper costing and

not forget to apply the cost-of-entry tests.

• Will the business be better off? Organisations should consider

diversification when new businesses present benefits in excess of a once off

yield, and organisations should employ a diversification of risk strategy only

as a by-product of corporate strategy and not as the primary motivator.

Page 57: THE IMPACT OF DIVERSIFICATION ON THE FINANCIAL …

2.5.4.4.4 Hamel and Prahalad

Hamel and Prahald (1996) wrote in their book “Competing for the future” that

organisations destroyed shareholder value in the 1970’s and early 1980’s, and

that diversification into areas where organisations lack knowledge and

capabilities was a disaster.

Hamel and Prahald (1996) argued that organisations tended to get involved in

areas they had no experience in and that growth and diversification around

organisations’ core competencies should be pursued. Hamel and Prahald

(1996, p. 322) define core competence as “the connective tissue that holds

together a portfolio of seemingly diverse businesses”. They argue that core

competence-based diversification reduces risk and investment and increases

the opportunity for transferring skills and best practice across business units

2.6 SOUTH AFRICAN STUDIES

From a South African perspective, there has been no systematic study of the

diversification-performance relationship. The apartheid policies of the past

drove South Africa into economic isolation, forcing many organisations to

diversify from the 1960’s to the early 1990’s.

From a corporate restructuring point of view an empirical study was conducted

by Bhana (2004), which measured the performance of corporate restructuring

through spin-offs of organisations that were listed on the JSE. In his study,

Page 58: THE IMPACT OF DIVERSIFICATION ON THE FINANCIAL …

47

which was conducted from 1988 to 1999, he found that the divesture by the

parent organisations via a spin-off had a positive outcome for both the parent

organisation as well as the spun-off organisation. Bhana (2004) found in his

sample of 47 voluntary spin-offs that were initiated by 19 parent organisations

that positive abnormal returns were achieved for up to three years beyond the

spin-off announcement date, thus suggesting that the South African

organisations that became more focused did benefit in terms of financial

performance.

This research report intends to conduct a study to compare the financial

performance of the industrial sector of JSE listed companies divided into

diversified organisations and focused organisations and to establish if the one

group’s financial performance is superior to the other group’s financial

performance.

Page 59: THE IMPACT OF DIVERSIFICATION ON THE FINANCIAL …

3. RESEARCH HYPOTHESES Various international studies focus on different measures to establish if

diversification results in greater economic performance. Palich et al. (2000)

found in their study that the two main measures that were used were accounting

and market based performance measures. In their study they found that

diversification was related to accounting and market performance outcomes.

The specific research hypotheses that will be used are a combination of the

accounting and market based performance measures:

Hypothesis 1: The Average Return on Equity (AROE) of the diversified

organisations is higher than the AROE of the focused organisations.

Hypothesis 2: The Average Return on Assets (AROA) of the diversified

organisations is higher than the AROA of the focused organisations.

Hypothesis 3: The Average Market Return (AMKTRET) of the diversified

organisations is higher than the AMKTRET of the focused organisations.

Hypothesis 4: The Average Earnings per share growth rate (AEPSGR) of the

diversified organisations is higher than the AEPSGR of the focused

organisations.

Hypotheses 1, 2 and 3 were used in the research conducted by Panday and

Rao (1998) in their study of 637 USA firms during the period 1984 to 1990.

Hypotheses 1 and 2 relate to accounting measures, while hypothesis 3 relates

to market based measures. The three performance measures were averaged

over the period of study per diversification category to calculate an Average

Page 60: THE IMPACT OF DIVERSIFICATION ON THE FINANCIAL …

49

Return on Equity (AROE), an Average Return on Assets (AROA) and an

Average Market Return (AMKTRET) per category, to be able to identify if the

one category of organisations performed better than the other.

Hypothesis 4 was used in the research conducted by Rumelt (1986) where the

Earnings per share growth rate were measured over the period from 1951 to

1970. The strategic categorisation of the organisations was conducted at three

points in time: 1949, 1959 and 1969 and the Earnings per share growth rates

were averaged per decade, and then further averaged over the entire period

from 1951 to 1970, resulting in an Average Earnings per share growth rate

(AEPSGR) per category.

4. RESEARCH METHODOLOGY

4.1 RESEARCH DESIGN

The research design used for the study was quasi-experimental research as

described by Welman and Kruger (2005). To define quasi-experimental

research it is important to define experimental research first to be able to

recognize the difference between the two.

Welman and Kruger (2005) define experimental research as research where the

units of analysis are exposed to something to which they otherwise would not

have been subjected. True experimental research is conducted where the

researcher has optimal control over the research situation and where the

researcher can assign the unit of analysis randomly to groups of design.

Quasi-experimental research described by Welman and Kruger (2005) differs

from true experimental research in that the researcher cannot randomly assign

a unit of analysis to the different groups of study.

The goal of this study was to categorise organisations listed in the industrial

sector of the JSE into two groups of 15 organisations as being diversified or

focused, based on the calculation of the SR of each organisation. It was for this

reason that the quasi-experimental research design was chosen as the

organisations had to be categorised into the two groups utilising the SIC code

measure as indicated in Appendix 1. The SR was calculated for the year 2001

Page 62: THE IMPACT OF DIVERSIFICATION ON THE FINANCIAL …

51

and 2005 to ensure that the organisations remained diversified or focused at the

start of the period, and at the end of the period.

4.2 UNIT OF ANALYSIS

Welman and Kruger (2005) define units of analysis as the members or elements

of a population. In the research conducted, the unit of analysis was the

organisations listed in the industrial sector of the JSE. The list of organisations

listed in the industrial sector was obtained from the daily financial press as listed

by The Business Day’s Market Wrap (2006).

For the purposes of the research, the organisations listed in the industrial sector

were grouped as either diversified or focused using Rumelt’s (1982)

Specialization Ratio (SR).

4.3 POPULATION OF RELEVANCE

Welman and Kruger (2005) define a population as an entire collection of cases

or units about which one wishes to make conclusions. The population of

relevance that applied to the research was the organisations that were listed in

the industrial sector of the JSE. In Table 11 below are the 58 listed

organisations that were listed in the industrial sector of the JSE which

represents the complete population of relevance of the research.

4.4 SAMPLE SIZE AND SAMPLING METHOD

The sampling method that was employed in the research was by way of a non-

probability convenient sample. According to Welman and Kruger (2005) non-

probability sampling is the probability that any unit of analysis will be included in

a non-probability sample and cannot be specified, and in some instances

certain members may have no chance at all of being included in such sample.

Albright, Winston and Zappe (2003) refer to non-probability sampling as a

judgement sample where no formal random mechanism is used and that the

sampling units are chosen according to the sampler’s judgement.

The organisations were analysed according to the three-digit SIC code analysis

in 2001 and 2005. The SIC code analysis was important to confirm if an

organisation was diversified or focused based on the information obtained in the

organisation’s published annual reports. The SIC code analysis was applied to

organisations that reported segmented revenues in the annual reports in 2001

as well as 2005 to ensure that an organisation was diversified or focused at the

beginning of the period, as well as the end of the period. The SIC code analysis

was conducted at the three-digit SIC code level whereby the various

classifications were assigned to the revenue streams of the organisations.

Once the SIC code analysis was completed, the organisation’s SR was

calculated utilising Rumelt’s (1982) classification. Rumelt (1982) developed

nine categories of diversification, while this research only focused on two levels

of diversification. Similar to the research conducted by Panday and Rao (1998),

Page 65: THE IMPACT OF DIVERSIFICATION ON THE FINANCIAL …

54

adjustments were made to the SR threshold in their research. The SR for the

focused organisations has been adjusted from 0.95 to 0.90, as it was found that

very few organisations SR was greater than 0.95 as indicated in Table 12

below.

Organisations were classified into two groups based on their SR. Organisations

SR that was greater than 0.90 in 2001 and 2005 were grouped as focused, and

organisations where their SR was less than 0.70 in 2001 and 2005 were

grouped as diversified organisations.

The following organisations were excluded from the samples:

• Organisations that were not listed on the JSE during the period of study.

• Organisations’ SR that did not remain constant in the diversified or focused

categories in 2001 and 2005.

• Organisations that have their primary listing in another country other than

South Africa.

• Organisations that had a separate listing for preference shares or options

listed as separate instruments to the ordinary shares.

Page 66: THE IMPACT OF DIVERSIFICATION ON THE FINANCIAL …

55

• Organisations that did not report separate revenue streams or where no

conclusion of separate revenue per business unit could be made

Each category of diversified or focused group had a sample of 15 organisations

so as to ensure similar sample sizes. The categorisation process was important

as the organisations’ financial performance was compared to identify which

group outperformed the other.

4.5 DETAILS OF DATA COLLECTION

The details of the data collection can be divided into two categories. The first

category related to the collection of data to determine the level of diversification

of the various organisations, and the second category related to the collection of

the performance data of the organisations once the categorisation of the

diversified versus focused was completed.

4.5.1 Data to determine the level of diversification

The data that was required to establish if an organisation was diversified or

focused was primary data. Welman and Kruger (2005) define primary data as

original data that has been collected by a researcher for the purposes of his or

her own study at hand. The organisations’ published annual reports were

required for the year 2001 as well as 2005 to be able to establish the revenue

earned per reported segment. The majority of the 2005 annual reports were

Page 67: THE IMPACT OF DIVERSIFICATION ON THE FINANCIAL …

56

available on the organisations’ websites, whereas the majority of the 2001

annual reports had to be requested from the organisations.

The reported revenues per segment and operational review description were

used to correlate to the three-digit SIC code to establish the revenue earned per

economic activity as described by the three-digit SIC code definitions. (An

extract from the CIPRO website is contained in Appendix 1).

The above process in establishing the three-digit SIC code per segment and

operational review was manual in nature as there is no public database

available in South Africa that has all the SIC code information available per

organisation. This was unlike the research that was conducted by Berger and

Ofek (1995), Delios and Beamish (1999) and Ushijima and Fukui (2004) where

databases with the relevant SIC code information was available. In the case of

the research that was conducted by Berger and Ofek (1995) in the USA, the

Compustat Industry Segment (CIS) database was used to extract the

segmented information.

Where additional information was required to clarify the operations of an

organisation the following additional sources were used:

• The internet websites of the particular organisation was consulted to gain a

further understanding

• Profiles bi-annually published “Stock Exchange Handbook”

• McGregor’s annually published “Who owns whom” handbook

Page 68: THE IMPACT OF DIVERSIFICATION ON THE FINANCIAL …

57

4.5.2 Performance data

Once the categorisation of the diversified versus the focused organisations was

completed, the performance data per organisation per year was required. The

performance data that was used was secondary data. Welman and Kruger

(2005) define secondary data as information obtained by individuals, agencies

and institutions other than the researcher himself. The performance data was

obtained from McGregor’s Bureau of Financial Analysis (BFANet) database,

which is a vendor that supplies financial data relating to listed companies to

subscribers.

The various performance data definitions and timeframes are listed below.

4.5.2.1 Return on Equity

The Return on Equity %( ROE %) data was obtained from the McGregor’s

BFANet database. The return data obtained was data per organisation per year

from 2001 to 2005. The definition of ROE % used by McGregor was:

ROE %= Profit attributable to ordinary shareholders

(Ordinary shareholders interest + Directors loans + Shareholders loans) X 100

4.5.2.2 Return on Assets

The Return on Assets %( ROA %) data was obtained from the McGregor’s

BFANet database. The return data obtained was data per organisation per year

from 2001 to 2005. The definition of ROA % used by McGregor was:

Page 69: THE IMPACT OF DIVERSIFICATION ON THE FINANCIAL …

58

ROA % = Investment Income + Operating Profit + Interest Received + Associated Income

Total Assets X 100

4.5.2.3 Market Return

The Market Return per organisation had to be calculated using the year end

share price and the dividends paid for the year. The year end share price and

dividend data was obtained from the McGregor’s BFANet database. The data

obtained was data per organisation per year from 2001 to 2005. The calculation

of the Market Return as used by Panday and Rao (1998) was calculated as

follows:

Market Return = Difference between the current year’s ending share price and

the previous year’s share price + Dividends paid for the year, divided by the

previous year’s share price.

In order to have calculated the Market Return, which was not available, two

data sets were obtained from the McGregor’s BFANet database to calculate the

Market Return:

• The Year end share price. The definition of year end share price used by

McGregor was:

Year end share price = Dividing the total monetary value of shares sold during

the last month of the financial year, by the number of shares sold during that

month.

• The ordinary dividends paid for the year. The definition of the ordinary

dividends used by McGregor was:

Page 70: THE IMPACT OF DIVERSIFICATION ON THE FINANCIAL …

59

Ordinary dividends = Ordinary dividends declared or provided in favour of the

various classes of ordinary shareholders in respect of the current financial

period.

4.5.2.4 Earnings per share

The Earnings per share (EPS) data was obtained from the McGregor’s BFANet

database. The EPS data obtained was data per organisation per year from

2001 to 2005. The definition of EPS used by McGregor was the Headline

Earning per share per year per organisation. Once the EPS was obtained, the

annual growth rate of the EPS had to be calculated.

Once all the performance data was received, the validity of the data had to be

verified. In some cases the data was incorrect and a full reconciliation and data

scrub was performed to ensure that the data was corrected for any errors. The

performance data from the McGregor’ BFANet database was compared to other

sources of financial information. The sources that were used to reconcile and

correct the performance data were:

• Profiles bi-annually published “Stock Exchange Handbook”

• McGregor’s annually published “Who owns whom” handbook

• Moneyweb website

• Sharenet website

4.6 PROCESS OF DATA ANALYSIS

Welman and Kruger (2005) mentioned that statistical techniques could be

divided into two categories. The first category was referred to as descriptive

statistics, and the second category was inferential statistics. The data analysis

below was divided into descriptive and inferential statistics.

4.6.1 Descriptive statistics

According to Welman and Kruger (2005) descriptive statistics refer to the

description and general characteristics of the data that was obtained for a group

of individual units of analysis. Descriptive statistics per performance

measurement were presented in a tabular format which consisted of the

following elements: mean, median, range, minimum, maximum and standard

deviation. Black (2004) defined the various descriptive statistical elements as

detailed in Table 13 below.

Table 13: Descriptive statistical elements Statistical Element Definition

n The amount of occurrences within the sample

Mean The long-run average of occurrences

Median The middle value in an ordered array of numbers

Range The difference between the largest and smallest values in a

set of numbers

Minimum The smallest value in a set of numbers

Maximum The largest value in a set of numbers

Skewness The lack of symmetry of a distribution of values

Kurtosis The amount of peakedness of a distribution

Standard deviation The square root of the variance that provides and indication of

the spread of the data Source: Black, K. (2004)

Page 72: THE IMPACT OF DIVERSIFICATION ON THE FINANCIAL …

61

4.6.2 Inferential statistics

Welman and Kruger (2005) defined inferential statistics as inferences a person

can make about a population index on the basis of a corresponding index

obtained from samples of populations. The use of parametric and

nonparametric statistics was used to make such inferences about a population

in hypothesis testing. Black (2004) referred to parametric statistics as statistical

techniques that were based on assumptions about a population from which the

sample data was selected. One of the assumptions of parametric statistics was

that the population was normally distributed.

The other statistical technique, nonparametric statistics, was defined by Black

(2004) as statistics that have fewer assumptions about the population, one of

which was the assumption that the population was not normally distributed.

4.6.2.1 Hypothesis Testing

In order to prove or disprove the hypothesis in the research it was necessary to

compare the means of the two independent categories of organisations. The

means of the focused organisations had to be compared to the means of the

diversified organisations of which parametric and nonparametric tests were

conducted.

The parametric test used in this research study was the one-tailed t-test where

the ρ-value approach was used. Albright et al. (2003) defines a one-tailed t-test

as one that is supported only by evidence in a single direction. The use of one

direction (one-tailed test) was used as the hypotheses tested the means of the

Page 73: THE IMPACT OF DIVERSIFICATION ON THE FINANCIAL …

62

performance data as greater for the one category than the other. Albright et al.

(2003) further noted that the use of the ρ-value approach of one-tailed t-tests

had become more popular, and defined the ρ-value approach as the probability

of seeing a sample with at least as much evidence in favour of the alternative

hypothesis as the sample actually observed. The smaller the ρ-value, the more

evidence existed in favour of the alternative hypothesis.

Rumelt (1986) and Varadarajan and Ramanujam (1987) studies made use of

Analysis of Variance (ANOVA) statistical techniques to prove or disprove their

hypotheses. The ANOVA test analysed data from a randomized sample and

measured whether there are differences in the means of two or more

independent groups. As Rumelt’s study and Varadarajan and Ramanujam’s

study analysed more than two groups, ANOVA was used to measure

differences between the means of the various independent groups. This

research study only focuses on two independent groups (focused and

diversified organisations), thus the one-tailed t-test was applied.

Similar to this research study, Panday and Rao’s (1998) study tested the null

hypothesis of equality of the means of each independent group, two groups at a

time, instead of an ANOVA test across all three of the groups. The null

hypothesis was rejected where the observed t-value was greater than the t-

critical level (significant level), which is similar to the one-tailed t-test where the

ρ-value approach was used in this study.

Page 74: THE IMPACT OF DIVERSIFICATION ON THE FINANCIAL …

63

The one-tailed t-test with the ρ-value approach was used and performed

according to the steps that were outlined by Berenson and Levine (1996). The

steps that were performed were as follows:

• The null hypothesis (H0) was stated.

• The alternative hypothesis (H1) was stated.

• The significant level alpha (α) was chosen.

• The sample size (n) was determined from the performance data.

• The ρ-value was calculated from the statistical software used. The statistical

software used in the research was the Number Cruncher Statistical System

(NCSS).

• The ρ-value was compared with the significant alpha (α) level.

• The outcome of the test determined if the null hypothesis (H0) was going to

be rejected or not. The following rules were applied to the observed ρ-

values:

o If ρ≥ α, the null hypothesis (H0) was not rejected

o If ρ< α, the null hypothesis (H0) was rejected

The one-tailed t-test with the ρ-value approach used above assumed the

sample distribution to be normally distributed. Berenson and Levine (1996)

remarked that for most population distributions, the sampling distribution of the

mean will approximately be normally distributed if samples of at least 30

observations were selected. Although each independent category of focused

organisations and diversified organisation had 15 organisations in each

category, five years data was used in the test. Each hypothesis test tested the

independent categories with a sample of 75 data observations (15 organisations

Page 75: THE IMPACT OF DIVERSIFICATION ON THE FINANCIAL …

64

multiplied by five years of data each), which was in excess of the 30 sample

observations mentioned by Berenson and Levine (1996).

Although the one-tailed t-test with the ρ-value approach assumed a normal

distribution, NCSS automatically performed additional nonparametric tests in

conjunction with the t-test that enabled the research to be tested with additional

tests. The additional nonparametric tests performed were:

• Aspin-Welch unequal-variance test. The test was performed where

unequal variances occur and gave another level of comfort when the tests

were performed.

• Mann-Whitney U test. Black (2004) mentioned that the Mann-Whitney U

test tested and compared the means of two independent samples. It was to

be used when there was doubt of the distribution being normally distributed.

Although the sample size of the two independent categories was greater than

30 observations and therefore could assume normality, the additional tests were

performed to confirm the results.

The tests were conducted per hypothesis whereby all the observations were

included in the sample. As there were large outliers present in the observations,

a second test per hypothesis was performed whereby the large outliers were

removed from the sample to evaluate the impact the outliers had on the results.

One additional test per hypothesis was conducted to evaluate the impact the

Page 76: THE IMPACT OF DIVERSIFICATION ON THE FINANCIAL …

65

removal of the outliers had on the results. Black (2004) defined an outlier as a

data point that lay apart from the rest of the observations.

4.7 LIMITATIONS OF THE RESEARCH

The limitations of the research that was conducted can be summarised as

follows:

• The population of the Industrial sector on the JSE limited the number of

organisations to 58. It would have been ideal to expand the research to all

the organisations listed on the JSE.

• The manual nature of calculating and interpreting the segmented and

operational overview revenue of each organisation to correspond to the

appropriate SIC code was judgemental at times. Where the SIC code

description did not match the description in the annual reports, a judgement

call had to be made to correspond the SIC code to the revenue segment as

closely as possible.

• The performance data had to be reconciled and data scrubbed to ensure the

data was accurate as errors were found.

• The sample size of 15 organisations per category was limited in size,

although there were 75 observations within the samples.

• Large outliers existed in the samples which skewed some of the test results.

The research methodology used in the research was a two step approach. The

first step was to calculate and determine the level of diversification per

Page 77: THE IMPACT OF DIVERSIFICATION ON THE FINANCIAL …

66

organisation and to categorise the organisations as being either focused or

diversified. The second step was to apply hypotheses using financial

performance data to prove if one category of organisations outperformed the

other.

5. RESULTS

The results of the research are divided into two sections, the first section reflect

the results of the classification of the organisations into either focused or

diversified organisations, and the second section shows the results of the

performance data obtained from the McGregor’s BFANet database as well as

the results of the hypothesis testing.

5.1 SIC Code classification

The summary of the results of the SIC Code classification per organisation into

the two categories as either focused or diversified is reflected below. The

detailed analysis of each organisation’s classification and three-digit SIC Code

breakdown and revenue per segment can be viewed in Appendix 2 (Focused

Organisations) and Appendix 3 (Diversified Organisations).

5.1.1 Focused Organisations

The classification of the focused organisations is listed in Table 14 below. The

15 focused organisations are listed in alphabetical order against which the

three-digit SIC code for the largest contributing segment to the revenue of the

organisation is listed. The three-digit SIC Code for the year 2005 with the

corresponding SR is listed as well as the three-digit SIC code and

corresponding SR for the year 2001, to ensure that the organisation remained

Page 79: THE IMPACT OF DIVERSIFICATION ON THE FINANCIAL …

68

focused at the beginning of the period and the end of the period of study. The

largest contributing segment for the purpose of classifying the organisation into

SIC Codes was obtained from the CIPRO website.

Out of the total of 58 listed organisations in the industrial sector of the JSE, 15

organisations were categorised as focused and15 organisations as diversified.

The remainder of the organisations were rejected from the samples due to the

following reasons:

• The organisations that did not remain constant as focused or diversified at

the start of the study period compared to the end of the period were not

included in the samples. An example of an organisation is:

o Kairos Industrial Holdings Limited whose SR was 0.51 in 2005 and

0.83 in 2001.

• Organisations whose SR were between 0.9 and 0.7 have not been used in

the data. Examples of the organisations are:

o Argent Industrial Limited whose SR was 0.89 in 2005 and 0.78 in

2001.

o Concor Limited whose SR was 0.81 in 2005 and 0.80 in 2001.

• Organisations which obtained their JSE listings after 2001 were not included

in the samples. The organisations listed after 2001 were:

Page 84: THE IMPACT OF DIVERSIFICATION ON THE FINANCIAL …

73

o Amalgamated Electronic Corporation Limited which listed in 2005.

o Consol Limited which listed in 2005.

• Organisations that did not have their primary listing in South Africa were not

included in the samples. The non-primary South African listed organisations

are:

o Bicc Cafca Limited as the primary listing is in Zimbabwe.

o Monteagle Holdings Societe Anonyme as the primary listing is in

Luxembourg.

• Organisations that did not report their segmented revenues sufficiently to be

used in the samples. Examples are Wilson Baily Holmes-Ovcon Limited and

KAP International Holdings Limited who did not clearly report or document

operational reviews to be able to link the revenues with a particular three-

digit SIC code.

5.2 Performance measure results

The results section of the performance data is divided into three sections. The

first section presents the results of the data that was obtained from the

McGregor’s BFANet database, the second section presents the descriptive

statistics of the performance measures and the third section presents the

results of the hypothesis testing.

The above data were used to test each of the four hypotheses which will be

discussed in the section below.

5.2.2 Descriptive statistics of the performance measures

The descriptive statistics relating to the performance measures are summarised

in Table 20 below. Two sets of tests are presented. The first set, (Hypothesis

Test 1) includes the tests whereby all the observations per category of focused

or diversified organisations were tested, and the second set of results

(Hypothesis Test 2) excludes the large outliers.

Page 89: THE IMPACT OF DIVERSIFICATION ON THE FINANCIAL …

78

The existence of large outliers in the 75 observations per category resulted in

the need to perform an additional test per hypothesis. The aim of the research

is to present and test all the observations in the samples (75 observations) as

the observations were actual financial data that was recorded by the

organisations. The additional test without the large outliers is done to examine

the impact on the results if they are removed.

5.2.3 Hypothesis test results

The results of the four hypothesis tests are presented below in tabular form.

The results include the one-tailed t-test with the ρ-value approach as well as

non-parametric tests that include the following:

• Aspin-Welch unequal-variance test

• Mann-Whitney U test for difference in medians

Page 90: THE IMPACT OF DIVERSIFICATION ON THE FINANCIAL …

79

The first section of the results in the tables indicates the results of the test

conducted on all the observations (75 observations), and the second section of

the results are the results where the large outliers have been removed to

examine what the impact of the results would be if the outliers were removed.

5.2.3.1 Hypothesis 1: AROE

The alternative hypothesis (H1):

The AROE of diversified organisations is greater than the AROE of the focused

organisations.

The null hypothesis (H0):

The AROE of diversified organisations is less or equal to the AROE of the

focused organisations.

H0: µAROEDiv≤ µAROEFocus

H1: µAROEDiv> µAROEFocus

Where µx = mean

As indicated in Table 21 below, the probability level (ρ) = 0.412851 ≥ 0.05

therefore it fails to reject the H0. It is important to note that this does not imply

the acceptance of the null hypothesis, rather that the alternative hypothesis is

not significant at the 5% alpha level and that the difference in the AROE

between the diversified organisations and the focused organisations is due to

sampling error.

Page 91: THE IMPACT OF DIVERSIFICATION ON THE FINANCIAL …

80

The second test conducted without the large outliers (72 observations) indicates

a probability level (ρ) = 0.441663 which also results in a failure to reject the H0.

The result of the hypothesis thus concludes that although the AROE of the

diversified organisations (12.1652%) is greater than the AROE of the focused

organisations (10.0272%), the difference is not statistically significant.

5.2.3.2 Hypothesis 2: AROA

The alternative hypothesis (H1):

The AROA of diversified organisations is greater than the AROA of the focused

organisations.

The null hypothesis (H0):

The AROA of diversified organisations is less or equal to the AROA of the

focused organisations.

H0: µAROADiv≤ µAROAFocus

H1: µAROADiv> µAROAFocus

Where µx = mean

As indicated in Table 22 below, the probability level (ρ) = 0.437266 ≥ 0.05

therefore it fails to reject the H0. It is important to note that this does not imply

the acceptance of the null hypothesis, rather that the alternative hypothesis is

not significant at the 5% alpha level and that the difference in the AROA

between the diversified organisations and the focused organisations is due to

sampling error.

The second test conducted without the large outliers (73 observations) indicates

a probability level (ρ) = 0.363419 which also results in a failure to reject the H0.

The result of the hypothesis thus concludes that the AROA of the diversified

organisations (16.7198%) is less than the AROA of the focused organisations

(17.0228%), and the difference is not statistically significant.

As indicated in Table 23 above, the probability level (ρ) = 0.023594 ≥ 0.05

therefore it fails to reject the H0, as the AMKTRET of the focused organisations

is greater than the diversified organisations. As the alternative hypothesis (H1)

stated that the AMKTRET of diversified organisations is greater than the

AMKTRET of the focused organisations, the AMKTRET of diversified

organisations is in fact less than the AMKTRET of the focused organisations.

The second test conducted without the large outliers (71 observations) indicates

a probability level (ρ) = 0.013151 which also results in a failure to reject the H0.

The result of the hypothesis thus concludes that the AMKTRET of the focused

organisations (51.16133%) is greater than the AMKTRET of the diversified

Page 95: THE IMPACT OF DIVERSIFICATION ON THE FINANCIAL …

84

organisations (30.81573%), the difference being statistically significant, and the

opposite outcome of what was expected.

5.2.3.4 Hypothesis 4: AEPSGR

The alternative hypothesis (H1):

The AEPSGR of diversified organisations is greater than the AEPSGR of the

focused organisations.

The null hypothesis (H0):

The AEPSGR of diversified organisations is less or equal to the AEPSGR of the

focused organisations.

H0: µAEPSGRDiv≤ µAEPSGRFocus

H1: µAEPSGRDiv> µAEPSGRFocus

Where µx = mean

As indicated in Table 24 below, the probability level (ρ) = 0.19595 ≥ 0.05

therefore it fails to reject the H0. It is important to note that this does not imply

the acceptance of the null hypothesis, rather that the alternative hypothesis is

not significant at the 5% alpha level and that the difference in the AEPSGR

between the diversified organisations and the focused organisations is due to

sampling error.

The second test conducted without the large outliers (72 observations in the

focused category and 71 observations in the diversified category) indicates a

probability level (ρ) = 0.256623 which also results in a failure to reject the H0.

Page 96: THE IMPACT OF DIVERSIFICATION ON THE FINANCIAL …

85

The result of the hypothesis thus concludes that the AEPSGR of the diversified

organisations (41.3218%) is greater than the AEPSGR of the focused

organisations (-50.9915%), and the difference is not statistically significant.

The results of the performance measures indicate that large outliers exist in the

test of the hypotheses. The hypotheses are tested inclusive of all the

observations and a second test without the large outliers. Although the tests

without the outliers indicate differences in the descriptive statistics, the overall

results remain the same. The aim of the research is to test the hypotheses

inclusive of all observations as the data are real financial data that are

observed.

Page 97: THE IMPACT OF DIVERSIFICATION ON THE FINANCIAL …

86

The overall results thus indicate that three of the hypotheses are not statistically

significant and that the differences in the average (mean) performance

measures of AROE, AROA and AEPSGR are due to sampling error. The

hypothesis of AMKTRET indicates however that the difference in the average

(mean) performance is statistically significant and that the AMKTRET of the

focused organisations is greater than the performance of the diversified

organisations and is the opposite of what the hypothesis intended to prove.

6. DISCUSSION OF RESULTS

The discussion of results chapter is divided into two sections. The first section

presents the manual SIC code and SR classification of organisations as either

focused or diversified, and the second section discusses the performance data

per hypothesis.

6.1 Classification of diversification

The SIC code classification and SR categorisation per organisation for the year

2001 and 2005 are presented in Table 14 for the focused organisations and

Table 15 for the diversified organisations. Table 14 and 15 present the high

level breakdown of the organisations per category, the three-digit SIC code as

well as the SR for the particular largest SIC code contributor. Appendix 2 and 3

detail the complete analysis of each of the organisations that are part of the

focused or diversified categories.

The research regarding the classification of the organisations represents the

two possible approaches used to ensure a thorough classification. The SIC

code and SR approach are found to be the best, as Montgomery (1982)

concludes that both approaches have strengths and weaknesses and that both

approaches, although manual in nature in this research, were also conducted

by Rumelt (1986), Markides (1995) and Harper and Viguerie (2002).

Page 99: THE IMPACT OF DIVERSIFICATION ON THE FINANCIAL …

88

It is evident from the Tables 14 and 15 that the resultant three-digit SIC code is

a categorisation at a high level, although Montgomery (1982) states that the

three-digit level of activity for the SIC code analysis is acceptable.

6.2 Performance measures

The key question in the research is to determine if diversified organisations

have superior financial performance over organisations that follow a focused

strategy. As South African organisations are integrated in the world economy

and divest more of their non-core businesses (Bhana, 2004) to focus on core

industries, it is necessary to determine if organisations that choose to diversify

or not outperform the other. It is also interesting to determine if the

organisations have a special capability due to regulation and the sanctions that

were placed on South African organisations, which compelled South African

organisations to invest and diversify by acquiring local companies, leading to

the formation of large diversified conglomerates (Rossouw, 1997).

This research report does not find that there are significant differences in

performance between the two groups in three out of the four hypotheses. The

one statistically significant result shows that the AMKTRET of focused

organisations is superior to the AMKTRET of diversified organisations.

Page 100: THE IMPACT OF DIVERSIFICATION ON THE FINANCIAL …

6.2.1 Hypothesis 1: AROE

The annual ROE% results of each organisation per category as being either

focused or diversified from the period 2001 to 2005 is presented in Table 16.

The results of the hypothesis test are presented in Table 21.

The null hypothesis fails to reject in both instances where the full sample of 75

organisations are tested, as well as where the outliers are removed from the

test. Although the AROE of the diversified organisations (12.1652%) is greater

than the AROE of the focused organisations (10.0272%) it is not statistically

significant and it cannot be proved statistically that diversified organisations

have a superior AROE than focused organisations. The test without the outliers

yields the same overall result, although the AROE of each category is narrower

and the standard deviation is also less for the second test.

The outliers excluded during the second test for the focused category are:

• -306.44% for Venter Leisure and Commercial Trailers Limited during 2001

and -227.35% during 2002

• -50.72% for Primeserv Group Limited during 2003

The outliers excluded during the second test for the diversified category are:

• 64.15% for Delta Electrical Industries Limited during 2005

• 52.21% for Jasco Electronics Holdings Limited during 2003 and -561.22%

during 2001

The results show that the focused organisations category has larger variance as

shown in the larger standard deviation. This could be an indication that the

Page 101: THE IMPACT OF DIVERSIFICATION ON THE FINANCIAL …

90

focused organisations are more volatile in terms of the return to shareholders as

focused organisations will tend to be more prone to economic cycles and more

sensitive to the parts of the economy that affect the focused organisations core

businesses.

The larger variance and standard deviation is also an indication of the portfolio

theory of finance whereby diversification leads to a smaller beta coefficient than

investments that are not diversified. The more diverse a portfolio of investments

are, the more likely the return of the investment will be to the return of the

overall market.

Rumelt’s (1986) study shows that the AROE amongst two of the four major

categories are statistically significant at the 5% alpha level during his research

of organisations from 1951 to 1970. The AROE of the four major categories are

indicated below:

• Single Business AROE: 13.20%

• Dominant Business AROE: 11.64%

• Related Business AROE: 13.55%

• Unrelated Business AROE: 11.92%

The dominant business category (AROE 11.64%) is statistically significant lower

than the mean, and the related business category (AROE 13.55%) is

statistically greater than the mean at the 5% alpha level. If the AROE of the

single business (AROE: 13.20%) and the related business (AROE: 13.55%) is

Page 102: THE IMPACT OF DIVERSIFICATION ON THE FINANCIAL …

91

compared, the differences are low, which in effect is the same measure and

result as this study, whereby the diversified AROE (12.1652%) is greater than

the focused AROE (10.0272%).

In comparing this study with the Panday and Rao (1998) study in the USA of the

organisations between 1984 and 1990, the AROE of the diversified

organisations (14.6%) was greater than the focused organisations (-1.6%),

which is the same finding as this study. However, the Panday and Rao (1998)

findings were proven as statistically significant at the 1% alpha level and that

the AROE of diversified organisations is superior to the AROE of the focused

organisations.

Another comparison of this study is the study of Hall and Lee (1999). The

difference in ROE is measured between USA and Korean organisations using

multiple regression techniques. The ROE of the USA diversified organisations

performed weaker than the ROE of the focused organisations, and is found to

be statistically significant at the 1% alpha level. Whereas the Korean

organisations show the same result as this study, that the ROE of diversified

organisations perform better than focused organisations, although it is not found

to be statistically significant. Similarly, Singh et al. (2001) study in the USA

reveals on an annual basis in 1994, 1995 and 1996 that the ROE of diversified

organisations is greater than the focused organisations. In two of the years,

1995 and 1996 the difference in ROE is statistically significant at the 5% alpha

level, whereas for 1994 it is not.

Page 103: THE IMPACT OF DIVERSIFICATION ON THE FINANCIAL …

6.2.2 Hypothesis 2: AROA

The annual ROA% results of each organisation per category as being either

focused or diversified from the period 2001 to 2005 is presented in Table 17.

The results of the hypothesis test are presented in Table 22.

The null hypothesis fails to reject in both instances where the full sample of 75

organisations are tested as well as the test where the outliers are removed from

the test. Although the AROA of the focused organisations (17.7198%) is greater

than the AROA of the diversified organisations (16.7198%) it is not statistically

significant and it cannot be proved statistically that focused organisations have

a superior AROA than diversified organisations. The results show that the

focused organisations AROA is marginally greater than the diversified

organisations, which is surprising, as it is expected for the AROA to yield similar

results to the test in Hypothesis 1. The test without the outliers yields the same

overall result, although the standard deviation is less for the second test.

The outliers excluded during the second test for the focused category are:

• -42.07% for Venter Leisure and Commercial Trailers Limited during 2001

• 49.16% for Pretoria Portland Cement Company Limited during 2005

The outliers excluded during the second test for the diversified category are:

• 64.97% for Delta Electrical Industries Limited during 2005

• -46.19% for Jasco Electronics Holdings Limited during 2001

The results show that the focused organisations category variance as shown in

the standard deviation is similar. This could be an indication that both

Page 104: THE IMPACT OF DIVERSIFICATION ON THE FINANCIAL …

93

categories of organisations’ total asset base are similar, and further

investigation can be done to determine the compilation of the asset base in

terms of net assets and intangible assets to gain a better understanding.

In comparing this study with the Panday and Rao (1998) study in the USA of the

organisations between 1984 and 1990, the AROA of the diversified

organisations (5.8%) was greater than the focused organisations (-1.9%), which

is the inverse finding of this study, however Panday and Rao (1998) findings

were proven as statistically significant at the 5% alpha level and that the AROA

of diversified organisations was superior to the AROA of the focused

organisations.

The study of Hall and Lee (1999) shows the difference in ROA as measured

between USA and Korean organisations. Similar to this study, the ROA of the

USA diversified organisations performed weaker than the ROA of the focused

organisations, and is found to be statistically significant, whereas the Korean

organisations show that ROA for diversified organisations perform better than

focused organisations, and is found to be statistically significant. Similar to this

research, the Singh et al. (2001) study reveals on an annual basis in 1994,

1995 and 1996 that the ROA of diversified organisations perform weaker than

the focused organisations. In two of the years, 1995 and 1996 the difference in

ROA is found not to be statistically significant, whereas for 1994 it is.

Page 105: THE IMPACT OF DIVERSIFICATION ON THE FINANCIAL …

94

6.2.3 Hypothesis 3: AMKTRET

The AMKTRET% results of each organisation per category as being either

focused or diversified from the period 2001 to 2005 is presented in Table 18.

The results of the hypothesis test are presented in Table 23.

The null hypothesis fails to reject in both instances where the full sample of 75

organisations are tested as well as the test where the outliers are removed from

the test. The AMKTRET of the focused organisations (51.16133%) is greater

than the AMKTRET of the diversified organisations (30.81573%), it is

statistically significant at the 5% alpha level and it can be proved statistically

that focused organisations have a superior AMKTRET than diversified

organisations. The results show the opposite of what is expected. The

hypothesis assumes that the diversified organisations will have superior

performance, but in fact the focused organisations outperformed the diversified

organisations by a large margin. The test without the outliers yields the same

overall result, although the standard deviation is less for the second test.

The outliers excluded during the second test for the focused category are:

• 280% for Venter Leisure and Commercial Trailers Limited during 2002 and

350% during 2003

• 184.62% for Digicor Holdings Limited during 2004

• 206.67% for Value Group Limited during 2004

The outliers excluded during the second test for the diversified category are:

• 246.48% for Transpaco Limited during 2003

Page 106: THE IMPACT OF DIVERSIFICATION ON THE FINANCIAL …

95

• 152.31% for Jasco Electronics Holdings Limited during 2003 and 167.86%

during 2005

• 135.58% for Howden Africa Holdings Limited during 2005

The results show that the focused organisations category has a larger variance

as shown in the larger standard deviation. This could be an indication that the

focused organisations are more volatile in terms of share price and dividends

paid during the year. The higher market returns could also be an indication of

the higher returns that are demanded from shareholders as the risk of focused

strategies might be higher. The volatile share price of the focused organisations

would be more prone to the liquidity and tradability of the securities, the

economic cycles and more sensitive to the parts of the economy that affect the

focused organisations core businesses.

In comparing this study with the Panday and Rao (1998) study in the USA of the

organisations between 1984 and 1990, the AMKTRET of the diversified

organisations (16.3%) is greater than the focused organisations (8.2%), which is

the inverse finding of this study, and similarly the Panday and Rao (1998) study

is proven as statistically significant and that the AROA of diversified

organisations is superior to the AROA of the focused organisations.

The study of Hall and Lee (1999) measures the difference in market-based

measures MVE between USA and Korean organisations. Although different to

AMKTRET which is also a market-based measure, the study found that the

Page 107: THE IMPACT OF DIVERSIFICATION ON THE FINANCIAL …

96

MVE of the USA diversified organisations performed weaker than the MVE of

the focused organisations, and is found to be statistically significant, whereas

for the Korean organisations it shows that the MVE for diversified organisations

performed better than focused organisations, and is found to be statistically

significant. It is interesting that Hall and Lee’s study of the USA organisations

yielded a similar result to this study, that focused organisations outperform

diversified organisations in terms of market return.

6.2.4 Hypothesis 4: AEPSGR

The AEPSGR % results of each organisation per category as being either

focused or diversified from the period 2001 to 2005 is presented in Table 19.

The results of the hypothesis test are presented in Table 24.

The null hypothesis fails to reject in both instances where the full sample of 75

organisations are tested as well as the test where the outliers are removed from

the test. The AEPSGR of the diversified organisations (41.3218%) is greater

than the AEPSGR of the focused organisations (-50.99147%) it is not

statistically significant and it proves not to be statistically true that diversified

organisations have a superior AEPSGR than focused organisations. The results

show a large difference in AEPSGR between the two categories due to the

outliers. The test without the outliers yields the same overall result in terms of

failing to reject the null hypothesis, although the second test AEPSGR are much

less dispersed. The second test result shows the opposite and that the

Page 108: THE IMPACT OF DIVERSIFICATION ON THE FINANCIAL …

97

AEPSGR of the focused organisations (27.20792%) is greater than the

AEPSGR of the diversified organisations (19.63085%), although the standard

deviation is less for the second test.

The outliers excluded during the second test for the focused category are:

• -7,500% for Venter Leisure and Commercial Trailers Limited during 2001

• 2,060% for Digicor Holdings Limited during 2004

• -343.33% for Primeserv Group Limited during 2004

The outliers excluded during the second test for the diversified category are:

• 1,662.50% for Transpaco Limited during 2002

• -305.71% for Jasco Electronics Holdings Limited during 2001

• -127.63% for Howden Africa Holdings Limited during 2001 and 476.19%

during 2002

The results show that the focused organisations category has a larger variance

as shown in the larger standard deviation. This could be an indication that the

focused organisations are more volatile in terms of the economic cycles and are

more sensitive to the parts of the economy that affect the focused organisations

core businesses.

Rumelt’s (1986) study shows that the AEPSGR is the measure that yields the

least amount of variation of all the other performance measures used in his

research of organisations from 1951 to 1970. This is evident in the relevant low

differences in the AEPSGR of the four major categories as indicated below:

• Single Business AEPSGR: 3.92%

Page 109: THE IMPACT OF DIVERSIFICATION ON THE FINANCIAL …

98

• Dominant Business AEPSGR: 5.99%

• Related Business AEPSGR: 7.64%

• Unrelated Business AEPSGR: 7.92%

The only category result that is statistically significant at the 5% alpha level is

the single business category measure of AEPSGR 3.92%, which is less than

the other categories. Similar to this study, the AEPSGR of most of the

categories in Rumelt’s study is not statistically significant.

The objective of the study is to determine if there is a difference in the financial

performance of organisations that follow a focused or diversified strategy. The

results prove that three of the four hypotheses (financial measures) cannot be

proven to be statistically significant, whereas one of the financial measures

indicates that the AMKTRET of focused organisations is superior to the

AMKTRET of diversified organisations. The result is the opposite of what was

expected, and there seem to be some synergies between the results of this

study and findings of other international studies.

7. CONCLUSION

7.1 Background

Corporate diversification is one of the fundamental strategic choices available to

CEO’s and managers of organisations to foster growth and profitability. The

question of whether diversification leads to superior performance has been

discussed, debated and researched since the early 1950’s. From an

international perspective, ample research has been conducted. The findings,

however, are inconsistent and there remains a lack of consensus regarding the

diversification-performance relationship.

In South Africa, there has been no systematic study of the diversification-

performance relationship. South Africa has unique circumstances due to its past

economic isolation, forcing many organisations to diversify from the 1960’s to

the early 1990’s. With the integration of South Africa into the world economy,

many organisations divested their non-core assets, and there is ample evidence

that organisations which divested their non-core businesses and focused on

core industries have also done well. However, there is also evidence that

diversified organisations are performing well and have had a successful track

record.

This research study was conducted to determine if a high degree of corporate

diversification results in superior financial performance versus a focused

strategy.

Page 111: THE IMPACT OF DIVERSIFICATION ON THE FINANCIAL …

100

7.2 Findings

The research was conducted on organisations that are listed on the industrial

sector of the JSE from the period 2001 to 2005. The research followed a two

step approach, first the organisations had to be categorised as either being

diversified or focused, and second once the categorisation was completed, the

financial performance of the two categories were statistically measured to

determine if diversified organisations outperform focused organisations.

The classification of the organisations as being diversified or focused was a

systematic approach adopted from international studies whereby a standard

industrial classification (SIC) code was assigned to the various revenue streams

of the organisations. As the information was not available on a public database,

a manual process had to be developed to measure the diversification level of

the organisations. The organisations that qualified and met all the criteria had to

remain as diversified or focused throughout the five year study period, which

resulted in two categories of organisations consisting of 15 organisations each.

The second step of the research entailed the comparison of financial data

between the two categories of organisations to determine if diversified

organisations outperformed focused organisations. Four hypotheses were

developed, whereby the Average Return on Equity (AROE), Average Return on

Assets (AROA), Average Market Return (AMKTRET) and the Average Earnings

per share growth rate (AEPSGR) of the diversified and focused organisations

were compared to each other over the period 2001 to 2005. The alternative

Page 112: THE IMPACT OF DIVERSIFICATION ON THE FINANCIAL …

101

hypothesis assumed that diversified organisations would outperform the

focused organisations, and the hypotheses were tested using the parametric

one-tailed t-test where the ρ-value approach was used as well as nonparametric

tests as confirmation of the findings.

The findings reveal that three of the four hypotheses (AROE, AROA and

AEPSGR) cannot be proven and are statistically insignificant. The AMKTRET is

the only hypothesis that could be proven and focused organisations are found

to be superior to the AMKTRET of diversified organisations, which is the

opposite of what was expected. In the case of the AROE, diversified

organisations outperform focused organisations, but the result is not statistically

significant. The AROA of the focused organisations marginally outperform the

diversified organisations, however is found to be statistically insignificant, and

the AEPSGR of diversified organisations is also superior to the focused

organisations, but is also found not to be statistically significant.

Although three of the four measures could not be proven, two additional

propositions could be investigated to add to this research study. The first

proposition is that diversified organisations have developed unique

competencies to operate effectively in their environments. The research needs

to be done to understand these competencies and how they impact the

organisations and their business units.

Page 113: THE IMPACT OF DIVERSIFICATION ON THE FINANCIAL …

102

The second proposition relates to the market analysis and expectations of

returns by the market. As the AMKTRET of the focused organisations were

greater than the AMKTRET of the diversified organisations, the globally

accepted belief of a market premium on the focused organisations can be

investigated. As per Appendix 3, the average Price / Earnings (P/E) ratio of the

focused organisations are compared to the P/E ratios of the diversified

organisations. The P/E ratios are similar, except for 2005 whereby the average

P/E ratio for the focused organisations are far greater than the average P/E

ratio of the diversified organisations. Further detailed studies could confirm the

belief that focused organisations P/E ratios would be greater than diversified

organisations.

7.3 In Summary

It is therefore found in this research study that three of the hypotheses

(performance measures) cannot be statistically proven between the diversified

organisations and focused organisations. One of the performance measures,

the AMKTRET of focused organisations outperform the AMKTRET of diversified

organisations and is proven to be statistically significant.

Page 114: THE IMPACT OF DIVERSIFICATION ON THE FINANCIAL …

103

7.4 Recommendations

The research was an attempt to use international research methodologies in the

South African context. Various recommendations are made to gain a better

understanding of diversification’s impact within the South African environment.

The first recommendation is to expand the study to other sectors on the JSE,

thus gaining a better understanding of all the organisations listed, and not just

on the industrial sector. A second recommendation is to extend the study period

over a period of between 10 and 20 years. The extended time period will

capture the changes South African organisations underwent when economic

sanctions were lifted, as well as the trend of organisations becoming more

focused since the 1990’s. A third recommendation is to increase the number of

categories used in research. As this research only focused on two extreme

categories of diversified or focused organisations, other categories such as

those in the model developed by Rumelt (1986) can be used.

From an international diversification perspective, it is recommended that

research be conducted whereby the level and performance be measured of

South African organisations that diversify their businesses and operations

internationally, thus measuring performance across geographical borders as a

diversification strategy.

The final recommendation is to establish a South African database where all

organisational information can be stored. A South African equivalent of the USA

Page 115: THE IMPACT OF DIVERSIFICATION ON THE FINANCIAL …

104

Compustat database can be developed where all the SIC code information,

annual reports, financial information, segmental information and organisational

activities can be stored in a central facility.
