ABSTRACT
This study investigated determinants of Cash Flow in the insurance industry, explained the time-
varying patterns of Cash Flows and forecasted future Cash Flows for Cash Flow risk management.
Sample financial data of 21 non-life insurance firms in Ghana from the year 2007 to 2015 was
used for this Study. Statistical analyses were made using a combination of pooled ordinary least
squares methods, principal component analysis and a novel Factor Augmented Autoregressive
(FAAR) Model to incorporate capital management, risk management, financial (investment)
management, firm characteristics, underwriting activities, and macroeconomic variables to
forecast future Cash Flows. The study provided new evidence regarding the relationship of firms’
management activities with Cash Flow risk management. Findings indicate that Cash Flow in the
Ghanaian insurance industry is significantly driven by capital ratio, short term and long term
investment ratios and industry-specific variables such as reinsurance ratio and net premium
received ratios. The results also validated the acute forecasting ability of FAAR (DFM) models in
predicting future Cash Flows.
In addition, the identification of possible variations in Cash Flows using the FAAR forecasting
model can help firms to further apply different financial instruments to manage and control Cash
Flow variations. i.e. Cash Flow Risks (Shortfalls).
Findings imply that firms can generate favourable Cash Flows to meet future obligations such as
dividend payments and unexpected insurance claims by controlling variables such as capital ratio,
short term and long term ratios, reinsurance and net premium received to assets ratios.

CHAPTER ONE
INTRODUCTION
1.1 Background to the study
Cash is king. It is true for entrepreneurs and it is also true for managers of financial institutions
(Born, Lin, & Wen, 2014). It is true that both financial and non-financial businesses are constantly
confronted with the risk of variations in their Cash Flow. In times of extreme economic volatilities,
prior knowledge on the trend of future Cash Flows would be very beneficial if it is available in
order to control for any associated risks. Proper Cash Flow forecasting and Cash Flow risk
management can, therefore, make huge differences between a surviving firm and one that will go
bankrupt or insolvent. There is much evidence suggesting that the high level of volatilities that
currently exist in the world of business is going to get worse in the years and decades ahead (Elahi,
2013). Younger firms most especially face uncertainties about their growth prospects. This
uncertainty exhibited in time through the realisation of future Cash Flow provide new information
about the health of a firm (Alti, 2003). This current trend of rising uncertainties that result in risks
for businesses calls for great attention to proper risk management with the potential of providing
a competitive advantage as well as promote firm solvency.
Differently stated, the life-blood of any business can be likened to its Cash Flow and if a business
in the course of operations runs out of cash and is unable to obtain new finance, it will become
insolvent. The level of Cash Flow within a firm is a clear indication of the future growth and
prospects of that firm. The Cash Flow of a firm can thereby be seen as a measure of the health of
that firm. Volatilities in the level of Cash Flow for a firm, therefore, need to be critically analysed
and projections accurately made as a first step in managing or controlling for inherent financial
risks that might be eminent in the firm’s operating activities. For any business, therefore, accurate
Cash Flow forecasting is essential at regular periods to provide information regarding the amount
2
of cash required at any point in time as well as determine how Cash Flow will be affected as a
result of a change in the risk factors that influence the level of cash.
With this in mind, the risks to Cash Flow thus have long been one most essential considerations
managers of firms make in their attempts to manage a variety of other risks. Management of firms
within the insurance industry are likewise keenly interested in Cash Flow statements, particularly
due to the unique underwriting risks uncommon to other industries but faced by this industry. By
this, forecasting Cash Flow, Cash Flow management as well as planning for future cash
requirements by businesses, has become vital to the process of financial management in a bid to
avoiding a crisis of insolvency and other financial risks. Essentially, the bottom line is the need for
firms to accurately forecast (predict) what is going to happen to their Cash Flow in the near future
so as to make sure they are able to service debts in time as a means to their very survival. The
frequency of forecasting Cash Flow, however, will depend strongly on the financial security of a
particular business under consideration, thus, whether a business is struggling with its finances or
its finances are stable (safe).
Cash Flows in the insurance industry can be generated mainly through underwriting activities,
financing and investment choices and even through risks management (Born et al, 2014). In
banking, one main operating activity, lending or deposits when demanded by customers leads to
an outflow of cash while loans when they are paid back or deposits lead to an inflow of cash to the
firm. Interests received or paid on these loans and deposits also contributes significantly to the
Cash Flow of these firms (Torfason, 2013).
Cash Flow as used in this study hence refers to the overall incomings and outgoings of cash within
an organisation as pertaining to its day to day activities. It thus refers to the sum of money that is
being transferred out of and into a business, particularly as affecting the liquidity of that business.

1.1.1 The Ghanaian Insurance Industry
According to the Annual Report of National Insurance Commission (NIC, 2015), the Ghanaian
insurance industry is currently made up of 25 Non-Life Companies; 19 Life Companies; 64
Broking Companies; 1 Loss Adjusting Company; 1 Reinsurance Broking Company and; 4
Reinsurance Companies. Despite these numbers, insurance penetration in Ghana is still very low.
Insurance penetration in Ghana for 2013 was 1.42% below the African average of 3.5%. This is
very low as compared to jurisdictions like Kenya and South Africa where penetration stood at
3.4% and 15.4% respectively (NIC, 2013).
In Damodaran (2013), any firm providing financial services or products to either individuals or
other firms is classified as a financial service firm. With this notion, financial service businesses
were categorised into four main groups from the viewpoint of how they make their money. Among
this classification was insurance firms which they classified as firms which make their income
primarily through premiums they receive from policyholders who seek insurance protection from
them. The study also identified income from investment portfolios as a second primary source of
income to insurance firms in order to service genuine claims. In measuring how big the financial
services sector is in the United States, the study summarised the market capitalisation of all
publicly traded financial service firms at the end of 2007 and the proportion of the overall equity
they represent in the market at the time. The results are presented in Table 1.1.
From the table, the proportion of overall market capitalization for insurance firms is 8.00 percent
equivalent to a market value of $4,029,009 in millions of US dollars. This stated value accounts
for about one-half of the overall market, in terms of market capitalization of the financial services
sector.

Thus, although insurance contributes highly to the financial sector of most jurisdictions such as
the United States of America, South Africa and Kenya among others, insurance penetration in
Ghana still remains very low. In Ghana, a majority of the insuring public deal primarily with Non-
Life Insurance companies mainly because of the Motor Vehicle Insurance, which was made
compulsory by the Motor Vehicle (Third Party) Act, 1958 (Act 42). This study posits that the low
insurance penetration in Ghana can partly be linked to the lack of public trust and confidence in
insurance companies reinstating policyholders to their former financial positions in an event of an
occurrence of a fortuitous loss which was insured against.
Fast forward to some unfolding occurrences in the Ghanaian insurance industry, the National
Insurance Commission in 2001, filed a court case for the winding up of “Great African Insurance
Company Limited” and further filed an application in 2003 for an order to audit the company.
Similarly, the Commission took some enforcement actions against Phoenix Insurance Company
Ltd owing to poor finances and bad management practices (NIC, 2005).
The Commission again in pursuit of its statutory function, served a notice to the general public
stating that, “Adamas Life Assurance Company Limited is undergoing regulatory intervention to
improve its operational efficiency”. This notice coupled with regulatory decisions taken by NIC

restricted the company from writing any new insurance business, renewing or varying any existing
ones among others (NIC, 2016). According to the draft NIC Annual Report (2015), the
Commission received 520 complaints during the year 2014 as against 380 in 2013 of which 407
of these were resolved. Out of these number of complaints, 193 were made against non-life
insurance companies while 327 of these complaints were filed against life insurance companies.
35 of these complaints were, however, associated with uninsured vehicles owners which in this
study can be likened to the class of individuals who have little trust in the insurance business. The
total number of complaints year on year as illustrated in Table 1.2 indicates a steady increase from
the year 2011 to 2014. The areas of common complaints in the area of non-life insurance as
reported in the NIC annual report, however, bother on the pursuit of motor claims with specific
relation to repudiation of claims by insurers, delay in settlement of claims, dispute over quantum
and delay in payment of settled claims. Table 1.2 highlights the distribution of claims from the
year 2010 to 2014.
Table 1.2: Distribution of the number of complaints from the general public
Source: NIC (2015)
This study posits that these failures recorded in the insurance industry may be due to poor Cash
Flow management as a number one contributing factor. The study also conjectures that these let-
downs if not appropriately resolved may lead to a total breakdown of the entire insurance industry
as policyholders will lose total confidence in insurance as a buffer for financial losses. This

research, therefore, sets to model Cash Flow which is the primary medium to claims settlement
and forecast future cash requirement of insurers as a first step to detecting and managing future
risks so as to protect policyholder and other stakeholder interests. The study focuses on Non-Life
Insurance which is the predominant class of insurance patronised in the Ghanaian market.
1.2 Research Problem
Future Cash Flow risks have been a major concern for many firms and the insurance industry
which faces, particularly, unique underwriting risks which are not observed in other industries is
no exception. Cash Flow of firms is determined by various activities that contribute to the overall
cash position. Cash Flow for the insurance industry is thus generated mainly through activities in
underwriting, financial and investment choices, capital management and risks management (Born
et al., 2014). Cash Flow generated within this industry thus dynamically interrelates with these
activities. Currently, the insurance industry in Ghana is faced with challenges relating to
policyholder complaints about insurer repudiations and delay in reimbursements, poor industry
capitalisation coupled with challenges in investment choices, as well as financial and risk
management. These challenges among other things bring to bear the insolvencies (NIC, 2005)
recorded within the industry over the decades. The current trend of uncertainty in firms’ Cash Flow
as related to their financial health, therefore, calls for a study to model Cash Flow. The bottom line
is, thus, any model developed to forecast insurers’ Cash Flow, must take into consideration all
activities related to the cash generating process of financing and investment, underwriting, capital
management, and risk management in order to manage the current Cash Flow risks of insurers in
the Ghanaian market.
7
1.3 Research Purpose
This study is targeted at ensuring the solvency of insurance firms within the Ghanaian insurance
industry by forecasting future Cash Flows with the intention of protecting the interest of
policyholders as well as increasing insurance penetration in Ghana. The forecasted Cash Flow of
a typical insurance firm will thus provide relevant guidelines for necessary risk management
practices.
1.4 Research Objectives
This study focuses on identifying Cash Flow risks of insurance firms by forecasting future net
Cash Flow as the primary indicator for Cash Flow variations (risk). Specifically, this research
identifies determinants of Cash Flow, as well as the impact of their management on future Cash
Flows. The primary objectives of this study are:
a. To identify the major determinants of Cash Flow in the cash generating process
b. To investigate the relationship between Cash Flow and capital management, investment
(financial) management, risk management, firm characteristics and underwriting activities
c. To forecast future Cash Flow of a typical insurance firm in Ghana.
1.5 Research questions
In order to have an in-depth understanding of this research, the key guiding questions are:
a. What are the main determinants of Cash Flow in the insurance industry?
b. What is the relationship between Cash Flow and capital management, investment
management, risk management, firm characteristics and underwriting activities?
c. What is the forecasted Cash Flow for an insurance firm at a given time (t)?
8
1.6 Research Hypotheses
Following the above research questions, the study tested the following hypotheses;
a. Capital management does not impact Cash Flow level
b. Firm characteristics do not impact Cash Flow level
c. Investment management does not impact Cash Flow level
d. Risk management does not impact Cash Flow level
e. Underwriting activities do not impact Cash Flow level
1.7 Significance of the Research
The significance of this study can be viewed from three (3) angles namely:
a. Research: This study goes beyond currently existing research on Cash Flow management
which largely had been conducted in the European and American countries by applying a
quantitative method to estimate and forecast future Cash Flow for insurance firms in
Ghana. Existing literature on Cash Flow risk management in Ghana and perhaps West
Africa is presently rare. This research serves as a useful contribution to the discussion of
the use of Cash Flow as an indicator of firm’s financial risk in developing countries and
especially in Ghana where insolvency is a major concern to insurers, insurance regulators
and policyholders aside other stakeholders.
It will also be of great worth to individuals and organisations interested in carrying out
similar or related studies on Cash Flow risk management in the future.
b. Practice: This study provides necessary signal and useful remedying guidelines for
insurance companies and stakeholders by estimating future cash requirements, subsequent
future financial health of a firm and drawing attention to activities that need critical
considerations. Findings will further inform the general public and insurance regulators
about the vulnerability of some insurance firms and hence protect customers and
9
beneficiaries. In effect, critical assessment and projection of future Cash Flow of insurance
firms will provide relevant insight and understanding to meaningful risk management
needs in insurance companies to prevent insolvencies
c. Policy: This study will provide valuable intuition which can help the regulator – the
National Insurance Commission (NIC), to enact policies and regulations to protect the
interest of both insurers and the insuring public in Ghana.
1.8 Definition of Scope and Limitation of Study
The scope within which this study is conducted is discussed in this section. It examines the
contextual validity of methods employed and the extent to which findings in this study can be
generalised.
In line with the research objectives, the study steps out to investigate the various drivers of Cash
Flow, particularly in the insurance industry. The methods employed are particularly appropriate as
extant empirical studies validate the diverse implication of dissimilar characteristics and
volatilities in forecasting future Cash Flows (Born et al., 2014; Stock & Watson, 2006;
McNicholas, 2002; Palepu, Healy, & Bernard, 2000). Thus, by concentrating on one
sector/industry, the influences of different dynamics that exist in other industries are minimised
and the reliability of findings is consequently greatly enhanced.
The sample used for this research considers financial ratios from licensed non-life insurance
companies within the Ghanaian insurance industry. Findings may thus not be generalizable easily
to life insurance or other industries within or outside Ghana due to some unique factors (such as
compulsory third party motor vehicle insurance and currently compulsory fire insurance for
commercial buildings) characterising the non-life insurance sector.
10
Although findings are aimed at fully informing insurers, insurance regulators and other
stakeholders of the various determinants of Cash Flow, the effective management of these
determinants is beyond the scope of this study. Also, although this study aims at assisting insurers,
insurance regulators and other capital market analysts to forecast more accurately future Cash
Flows as a means to the detection of future possible Cash Flow risks, the optimum management
procedures of possible risks in future Cash Flow are beyond the scope of this study. The detection
of these risks through projected Cash Flows will, however, assist firms to make improved financial
decisions.
Secondary accounting data from the financial reports of insurance firms were utilised in this study.
The sampled data is historic in nature and covers the period of 2007 to 2015. This period was
particularly chosen to reflect the current economic condition of non-life insurance in Ghana and
the regulatory impact of the 2006 ACT (ACT 724) which prohibited the forming and existence of
composite insurance companies. The study, however, made no comparable inference on the
performance of non-life companies before and after the enactment if this ACT (ACT 724). The
validity and robustness in the forecastability of Cash Flow using dynamic prediction models were,
however, authenticated using a holdout sample (2015 quarterly data).
1.9 Chapter Outline
The rest of the study is organised in the following manner:
Chapter two comprises a review of relevant literature on Cash Flow and cash holding behaviour
of firms so as to set a foundation for the research. It explores extant literature pertinent to this study
to ensure familiarity with existing body of knowledge and the position of this current study. The
literature review also highlights the conceptual framework for the study, clearly outlining the
research gap to be filled.
11
Chapter three explains the research methodology and discusses the population and sampling
undertaken as well as the data collection methods employed with relevant justification for each
selected research method.
The fourth chapter covers estimations, presentation, analysis of the results obtained using some
descriptive and inferential statistics.
The fifth chapter summarises the research findings, conclusions and make recommendations based
on findings with respective implications.
1.10 Chapter Conclusion
This chapter contained a comprehensive overview of the background, a brief description of the
Ghanaian insurance industry, a statement of the research problem and the research purpose. The
objectives and research questions guiding the research as well as hypotheses facilitating an in-
depth understanding and direction for the study were also provided. A justification to the
significance and the contribution of this study to the current body of literature, to policy, practice
of insurance as well as the conduct of future research was also provided. This chapter concluded
with a discussion of the scope of study and a comprehensive outline to the rest of the study.
The ensuing chapter presents a thorough examination of relevant literature related to the study.

CHAPTER TWO
LITERATURE REVIEW
2.1 Introduction
This chapter reviews the theoretical and empirical basis upon which the thoughts and
opinions developed in this study are constructed. The chapter reviews relevant extant literature
associated with the research topic as expressed by various authors and researchers and some
regulatory bodies. Specifically, the chapter contains literature on the background and
developments in the insurance industry of Ghana, the regulatory structure and bodies in order to
provide an overview of the financial reporting and operative environment of insurance in Ghana.
The chapter reviews relevant literature on the importance of forecasting future Cash Flows and
highlights on the accrual and cash accounting principles as two parent disciplines in financial
information reporting. Thus, literature relating to the use of accruals as well as Cash Flows as
either aggregated or single predictors of future Cash Flows are reviewed.
This chapter also contains an overview of Cash Flow in the insurance industry as well as literature
on some grounding theories on cash holding practices of firms. By this, the chapter reviews
literature to examine the major determinants of the Cash Flow of firms and the relationships
existing between Cash Flow and key management practices of firms.
Also, prior studies on the value relevance of accounting information in explaining share market
returns and the ability of derived financial ratios from this accounting information as proxies for
the prediction of financial distress were reviewed.
This chapter forms the basis for the regression models used in the next chapter for empirical
estimation and finally ends with a conclusion.

2.2 Overview of Cash Flow in the Insurance Industry
Insurance companies are financial institutions with financial objectives. In financial accounting, a
Cash Flow statement refers to a statement on finances showing how changes in income and balance
sheet accounts affect cash and cash equivalents, as a result of transactions in operating, investing
and financing activities (IASB, 2001). In essence, the Cash Flow statement for firms concerns with
the flow of cash into and out of the business. It captures both current operating results as well as
accompanying changes in the balance sheet. Cash Flow statements are useful as analytical tools in
determining the short-term viability of a company, principally its ability to pay bills since bills are
paid not against income but against cash. Timely availability of cash, therefore, can distinguish
between successful operations and closure (Beck, 1994). Insurers’ overall risk of insolvency,
therefore, links strongly with Cash Flow volatility which results through a myriad of individual
underwriting, financing and investment decisions of firms in the midst of macroeconomic variables
like inflation, interest rate, unemployment and GDP growth rates.
The net Cash Flow of a firm over a period (typically a quarter, half year or a full year) is equivalent
to the change in cash balance over this period. It is positive if the cash balance increases (more
cash becomes available) and negative, if the cash balance decreases. In general, the net of Cash
Flows of a project are in the following classifications:
a. Operational Cash Flows: This is simply, cash received or expended as a result of the
internal business activities in a firm.
b. Change in Net Working Capital: This is the flow of cash into or out of a company as a
result of the cost or revenue accruing to a company through its short-term assets.
c. Capital Spending: This is the cost or gains associated with the company’s fixed asset,
such as cash used to purchase a new equipment or cash which is gained from selling an old
equipment.
14
In order to maintain a smooth Cash Flow, therefore, manipulating practically every facet of a
business is required (Bodunrin, 2016). In insurance, activities in underwriting, financing, investing
as well as risk managing are essential in a successful Cash Flow management of regulating the
amount of money flowing into and out of a business. Increasing Cash Flow in a venture will imply
a reduction in the amount of fixed capital needed to support a given level of business operations.
An increased and consistent Cash Flow in a business also creates a predictable pattern in
businesses, enabling planning and budgeting for future growth.
2.3 Theories on Cash Holding Practices of Firms
The holding of cash and other liquid assets in a world of perfect capital markets are totally
irrelevant (Opler, Pinkowiz, Stulz, & Williamson, 1999). Thus, if the level of Cash Flow
unexpectedly turns out to be low, to the extent that a firm will have to raise external funds to
maintain their operations as well as invest, it can do exactly so at an absolutely zero cost. This will
be so since there is no opportunity cost for holding liquid assets in such a world due to the absence
of liquidity premium. The shareholder wealth for a firm will, therefore, remain unchanged if a firm
invests borrowed funds in liquid assets. Alternatively, if it becomes costly to run short of liquid
assets, firms will compare the marginal benefit of holding liquid assets to the marginal cost of
holding those assets. A firm running short of liquid assets is the situation in which it has to reduce
investments, retain dividends, raise external funds or sell its assets or securities. Consequently, the
importance of efficiently and effectively managing cash and other liquid assets by organisations
has become an important ingredient to a competitive financial environment and an imperative
research space in recent years.
Decisions regarding dividend payout, Cash Flow management, working capital and investment
plans are all very significant in corporate cash management, principally, in maintaining an optimal
level of cash (Tahir, Alifiah, Arshad, & Saleem, 2016). The optimal level of cash holding
15
behaviour of firms is grossly related to some grounding theories which are much more relevant to
cash management practices of these firms. Based on these financial theories, several studies have
been conducted across different economies around the globe. Initially, the majority of these studies
have been conducted with focus on firm cash holding trends and behaviour principally in the
United States (Chang-Soo, Mauer, & Sherman, 1998; Faulkender & Wang, 2006; Bates, Kahle, &
Stulz, 2009; Gao, Harford, & Li, 2013). Conclusions from these strand of literature are, however,
mixed relatively and will be challenging to generalise these results in other contexts due to varied
financial and economic environments. Nonetheless, other studies such as Chen and Mahajan
(2010), found some similarities in the practices of firms in cash management across developed
countries while Iskander-Datta and Jia (2012), in their comparative study of US firms with other
firms in developed countries, found differences in cash management behaviour of firms across
these countries as mainly attributing to institutional differences in these firms. Again, Kusnadi and
Wei (2011), in a study found great variations in the cash holding level of firms in developed and
developing countries. Although these findings could hardly be generalised, several theoretical
perspectives have been framed in defining firms’ cash holding behaviour and practices. These
theories include the trade-off theory, pecking order theory and free Cash Flow theory
(Wasiuzzaman, 2014).
2.3.1 Trade-off Theory
According to this theory, firms cash holding decisions are made considering the marginal cost and
benefits associated with the level of cash to hold in order to maximise shareholder’s wealth
(Dittmar, Mahrt-Smith, & Servaes, 2003). The benefits of holding cash according to the theory of
Keynes (1936), result from the motives of liquidity assets: transaction cost motive, precautionary
motive, and speculative motive.
16
2.3.1.1 Transaction Cost Motive
In relation to this theory, firms are able to avoid or save transaction costs that may arise as a result
of raising funds or liquidating assets by holding enough cash. According to Tobin (1956), Miller
and Orr (1966) and Dittmar et al. (2003) as cited in Tahir, Alifiah, Arshad, & Saleem (2016), firms’
transaction motives for holding cash are only to overcome the high opportunity cost of raising
funds in the absence of higher or enough cash levels.
2.3.1.2 Precautionary Motive
Precautionary motive for holding cash is another motivation for the amount of cash held by firms.
This motive reveals that the level of cash held by firms enables them to finance their investments
and projects using cash when other sources of financing fail or are unavailable. Additionally, firms
invest in liquid assets aside enhancing their cash level, as a means to overcome the probability of
very high cost of external financing to their activities (Ozkan & Ozkan, 2004).
2.3.1.3 Speculative Motive
Speculation as one of the motives for holding cash argues that economic agents hold cash or
marketable securities so as to make gains from future increments in an interest rate. By this,
benefits are firstly weighed against alternative costs of holding cash, as liquid assets in general,
generate comparatively very low rates of return. Efficient management of cash, however, holds a
significant potential for reducing financial distress (Ferreira & Vilela, 2004).
Despite the numerous benefits of holding cash, there exist also several drawbacks. As stated by
Jensen (1986), cash holdings of firms could result in an increase in agency cost. Also, firms with
very high cash holdings are highly restricted in their access to the capital market for financing.
This situation could empower managers to pursue their own interests rather than that of
shareholders as corporate managers can afford to stay away from the capital market monitoring.
17
In addition, the rate of return on such liquid assets is low due to liquidity premium which explains
the differences between two separate types of financial instruments that have the same qualities
but liquidity. Also, double taxation according to Chang-Soo et al. (1998) can be counted as one of
the drawbacks to cash holding at the corporate and individual level if it is distributed to
shareholders.
In order to reflect the trade-off theory in the cash holding practices of firms, extant empirical
studies incorporated different proxies as determinants of holding cash. Wasiuzzaman (2014), Uyar
and Kuzey (2014), Al-Najjar and Belghitar (2011) and Ferreira and Vilela (2004) for example, in
their empirical studies employed leverage, firm size, dividend pay-out, liquidity and risk, to
examine firm’s cash holding standpoint as related to the trade-off theory. The findings in these
studies, however, provided mixed results and which can create problems when generalisations are
made due to the unique macro environment of other economies. Afza and Adnan (2007),
Faulkender and Wang (2006) and Ozkan and Ozkan (2004), emphasised that the output of
investment and financing activities is cash. Firms that generate positive Cash Flows from their
operations, therefore, finance their investments and projects with these internal funds and remains
reliant on keeping large cash reserves on their balance sheets. Likewise, Gao et al. (2013)
conducted a comparative study of the cash policies in private and public firms in the United States
and found out that, private firms hold high Cash Flows as well as liquid assets.
Their arguments, however, are inconsistent with real trade-off prediction which predicts firms with
high Cash Flows to focus more on debt in order to minimise tax liabilities. Contrary to this, studies
such as Ozkan and Ozkan (2004), Alles, Lian, and Xu (2012), Azmat (2014), Uyar and Kuzey
(2014) and Wasiuzzaman (2014) saw significance in the role of optimal cash level as a support to
the trade-off theory. Cash holding mechanisms in relation to the trade-off theory as studied in
extant literature using mainly firm-level data, however, could be different across sectors as they
18
are influenced by various degrees of dynamics and competition within an industry (Tahir, Alifiah,
Arshad, & Saleem, 2016). This theory, therefore, needs to be validated empirically at sector levels
in the future.
2.3.2 Pecking Order Theory
Another grounding theory pertinent to Cash Flow management is the pecking order theory. This
theory was first proposed by Myers (1984) and Myers and Majluf (1984). According to them, firms
follow some kind of order in deciding the source of funds to use in financing their investments.
Based on this theory, firms firstly prefer financing their projects using internal funds. Secondly,
firms will adjust dividend levels of shareholders, even if dividends lean towards or follow some
sticky policies. Firms will thereafter decide to sell liquid assets in the absence of the earlier
mentioned sources before finally considering external capital sources as a last resort in financing
investments and projects. Following this order, firms will prefer debt to hybrid securities if
external financing is needed and finally resort to the issuance of equity (Myers, 1984). Tahir,
Alifiah, Arshad and Saleem (2016), explained this order as coming from the theory of asymmetric
information and managers by their superior knowledge on investments have an obligation to
minimise costs related to this issue.
Also, managers are agents who are supposed to act in the sole interest of the firm’s current owners
and will consequently try to issue new shares at the highest possible price. Equity investors,
however, who are conscious of this issue of information asymmetry will demand higher risk
premiums and thereby increase the cost of investment financing using equity. This logic, therefore,
is the reason behind firm’s preference for debt over equity (Myers & Majluf, 1984).
19
Thus, the level of cash holding is highly a result of the investment and financing decisions faced
by firms. The Cash Flow of firms is used to finance investment projects, repay debts when they
are due and thereafter accumulate any unused Cash Flow as cash balance if possible. Firms will,
however, resort to cash reserves as a safeguard to avoid external sources of financing when Cash
Flow is unable to cover expenditure. Hence, an additional financing is required if cash and
Operating Cash Flow are insufficient to cover all expenses. This stands to reason that, the amount
of cash holding of a firm highly depends on the cash inflow and cash outflow variations in order
to identify an optimal cash holding level. In a study to test the validity of both the trade-off and
pecking order theory and their influence on the cash holding behaviour of firms, results indicate
that both theories significantly explain the level of cash holdings of firms.
Again, Ferreira and Vilela (2004) argued that firms use cash for investment activities besides
paying debts and therefore, in return, firms hold higher liquidity. Likewise, Dittmar et al. (2003)
stressed that firms that have high Cash Flows distribute dividend smoothly and conversely, rely
on debt financing as well as holding high cash reserves.
Importantly, however, Wasiuzzaman (2014) while investigating the cash management behaviour
of firms in the context of Malaysian firms, indicated that both pecking order and static trade-off
theories have still been unable to explain the behaviour of firms fully. In contrast, Kim et al. (2011)
in their sector level study argued that firms with high growth opportunities have a tendency to hold
high levels of cash while firms with high capital and expenditures have lower cash ratio. These
results, however, contradict with pecking order theory.
In essence, firms which practice the pecking order theory of holding cash, therefore, tend to hold
more liquid cash as they prefer internal sources to external ones in financing investment projects
and hence reduces their Cash Flow risks.
20
2.3.3 Free Cash Flow Theory
Managers of corporate organisations are basically agents to shareholders who are the principal
owners of the organisation. An agent representing a principal, therefore, has the sole obligation to
serve the interest of the principal. The problem, however, at hand is that the agent might have
objectives and interests other than that of the principal and could act to accomplish these objectives
to the detriment of the principal (Tahir et al., 2016). The level of cash held by a manager can also
lead to an agency problem between shareholders and managers.
The analysis of such conflicts relating to free cash flow theory is gaining major attention in
financial literature. The free cash flow theory according to Jensen (1986), states that managers
prefer to hold high cash levels so as to enhance the size of total assets within their control. These
managers by this try to gain distinctive powers in the investment and financing decisions of their
firms which may lead to overinvestment issues (Ferreira & Vilela, 2004). Ferreira and Vilela
(2004) further argued that firms which have strong affiliations with banks and firms who practice
in superior investor protection countries tend to hold lower cash levels.
In a similar vein, Afza and Adnan (2007) described the optimal level of liquid assets as very
significant to the smooth functioning of the firm’s activities. With regards to the free cash theory,
it is argued that management of firms may hoard cash as it does not want to make payouts to
shareholders so as to hold these funds within the firm. By this, Drobetz and Grüninger (2007)
supported this argument and revealed that dividend payment to shareholders are related to cash
reserves as management may accumulate cash by reducing dividend or does not make payouts at
all to shareholders, in order to keep funds within the firm.
21
Based on both empirical and theoretical studies relating to cash holding practices of firms, it is
clear that trade-off, pecking order and free cash flow theories though not mutually exclusive,
predict uncertain roles of diverse financial environments in cash holding behaviour of firms.
However, no study in available extant literature gives preference to any single theory for
determining cash holding behaviour at both firm and industry level. This, therefore, warrants an
empirical study to analyse both theory and financial factors that best describe the cash holding
mechanism at the firm and industry levels.
2.4 The importance of Future Cash Flow Prediction.
The availability of an optimum level of Cash to a firm is “king”. This is because a firm can be
operating at a profit but suddenly go insolvency if it runs out of cash in the course of business and
cannot obtain cash (Keown, Martin, Petty & Scott, 2005; Born et al., 2014). Both financial and
non-financial organisations are constantly faced with the risk of variations in their flow of cash.
The receipts coming into an organisation must exceed their cash payments in the long run so as to
ensure the solvency of that organisation. For firms, the timing of cash receipts and when it can be
invested as well as when cash can be paid back to shareholders as a dividend is of great concern
(Keown et al., 2005).
Financial information users are, therefore, primarily concerned with the ability of firms to generate
Cash Flows that are favourable to future financial obligations. Financial decisions of firms are,
however, linked to the timing, volume and uncertainties in future Cash Flows (FASB, 1978).
According to Elahi (2013), the current high level of volatilities in the world of business will grow
worse in the years to come. It, therefore, becomes imperative for analysts and business players
especially younger firms which most especially face uncertainties in their growth prospects to
obtain prior knowledge on the trend of their future Cash Flows. The uncertainties in the growth of
22
young firms are exhibited through the passage of time with the realisation of future Cash Flow and
make available evidence about their financial health (Alti, 2003).
Accounting information reported by firms is increasingly gaining usefulness to their users in
forecasting future Cash Flows as a foundation for making sound financial decisions (Obinata,
2002). In the United States, the call for Cash Flow prediction by investors in the capital market
has been on the rise especially for firms with unstable earnings, large accruals, varied accounting
practices choices and high capital intensiveness (DeFond & Hung, 2003). Financial analysts, as
part of their main activities, make use of financial information in order to forecast the performance
of a firm as related to earnings, Cash Flows beside share prices (Ramnath, Rock, & Shane, 2008).
Previous studies have, therefore, validated the use of accounting information as a crucial source of
data for executing the decision-making process by analysts (Chang, Khana, & Palepu, 2000; Alti,
2003). Forecasting future Cash Flows with data obtained from reported accounting information,
therefore, aids in the appraisal of investments from the long-term and short-term perspectives,
valuation of securities, valuing credit and facilitating the process of decision making in an
organisation with the ultimate goal of ensuring the profitability and solvency of a firm.
2.5 Review on Determinants of Cash Holdings of Firms
The factors influencing the inflow and outflow of cash within a firm to a large extent determines
the level of cash held by that firm. There are various motives based on theory that determine the
amount of cash held by firms at any point in time. These motives include for example the
precautionary and the transactionary motives considered by Keynes (1936) as the main reasons
defining the level of cash in a firm. Bates et al. (2009), Foley et al. (2007) also identified the tax
motive while the agency motive was also pointed in Jensen (1986). With all of this said, however,
the ultimate goal in cash management whatever the motive, should be to have just enough cash but
not a cedi more. There exist an increasing number of research conducted with a focus on analysing
23
the cash management behaviour and define the determinants of cash holdings in relation to the
idea of a target cash level of firms, which stays in line with the capital structure analysis (Jani et
al., 2004). In Drobetz, Grüninger, and Hirschvogl (2010), the assumption of frictionless capital
markets makes cash holdings irrelevant, however, the trend of corporate cash holdings demands
the relaxation of this assumption. The trade-off theory, pecking order theory, and the Free Cash
Flow hypotheses become prominent in the debate on corporate cash holdings if information
asymmetry, transaction costs and agency costs are considered. These theories play the best part in
determining the influence of various firm and board characteristics on the level of cash a firm
holds.
2.5.1 Firm Characteristics
As cited in Wasiuzzaman (2014), Opler, Pinkowiz, Stulz, & Williamson (1999) in their cash model
identified some firm characteristics which to a large extent determine the normal level of cash
held. The ensuing section discusses some variables influencing the level of cash held by firms with
their expected relationship with cash holdings of firms.
Size: The size of a firm plays significant roles in determining their financial performance. Due to
the existence of economies of scale in cash management, smaller firms have the greater
possibilities of being financially distressed aside very high and expensive external sources of
financing (Ferreira & Vilela, 2004). This is primarily due to the higher information asymmetry
(Ozkan & Ozkan, 2004) these smaller firms suffer. According to prior studies, larger firms, in
reality, have better credit ratings and bank credit lines which together help them assess funds when
the need be. Again, the ability of these firms to raise large amounts of capital places them at an
advantage to exploit economies of scale (D'Mello, Krishnaswami, & Larkin, 2008).
24
Consequently, the trade-off theory foretells an inverse relationship between the size of a firm and
the level of cash holdings of that firm. In line with this argument, the negative relationship
predicted by the trade-off theory points strongly to the transaction motive of holding cash (Bates
et al., 2009). In a different argument, (Opler et al., 1999; Ferreira & Vilela, 2004; Jani et al., 2004)
asserts that large firms are doubtlessly more successful than their counterpart small ones and hence
have higher levels of cash after they control for investments. By their argument, there exists a
positive relationship between firm size and the level of cash holding.
Thus, judging from the perking order theory perspective, large firms tend to have higher cash
levels due to their preference for internal funds as the first priority in financing their investments.
In a similar argument, Ferreira and Vilela (2004) using the agency theory predicts that the
relationship between firm size and the amount of cash holding remains positive due to the fact that
large firms possess larger shareholder dispersion and therefore a poorer chance of takeover
attempts. This condition hence offers managers the discretionary authority over the firm’s financial
and investment policies and decisions, giving them the edge to hold large amounts of cash and
other liquid assets.
According to the predictions of these three theories (trade-off, pecking order and agency theories)
therefore, the effect of the size of a firm on the level of cash holding can either be negative or
positive depending on the theory applied.
Capital expenditure: Firms with high capital expenditure according to Oppler et al. (1999) tend to
have increased levels of liquid assets. By this reasoning, they explained stating that, by applying
the static trade-off theory, the positive relationship expected between the level of capital
expenditure and cash holding will arise since firms will require more cash or liquid assets in order
to pursue its capital requirement needs. Bates et al., (2009) in a similar argument predicted that
25
capital expenditure of firms can be used as a good proxy for firms’ financial distress costs and/or
investment opportunities hence leading to a direct relationship.
Jani et al. (2004 highlighted that firms that have high capital expenditure levels will as a way of
avoiding extra transaction costs associated with raising external capital coupled with the
opportunity costs that come with holding an insufficient level of resources tend to hold more cash.
In a dissimilar argument, however, Opler et al. (1999) point out that, relating this relationship with
the pecking order theory, firms that have higher capital expenditure will expend available cash or
liquid assets for this purpose and thereby have little internal resources. These firms will hence
accumulate less cash leading to an expected negative relationship.
Bates et al. (2009), further explained that if a firm uses capital expenditure as a means of creating
assets that can be later used as collateral, then this enables managers to take up more debt. This
increase in their debt capacity will lead to a reduction in their demand for cash and/or liquid assets.
Likewise, they argued that when there arises an unexpected need to invest in operations due to a
positive shock in productivity, a temporary increment in capital investments will lower the
capacity of firms to accumulate cash.
By these arguments, the expected relationship between the level capital expenditure and the
amount of cash holding may either be negative or positive.
Leverage. The leverage of a firm possibly will lead a firm into financial distress or into bankruptcy
(Wasiuzzaman, 2014). Holding high volumes of debt or liabilities as against the assets available
to that firm increases the probability of bankruptcy. As stated by Deloof (2003), a firm that is
highly leveraged will need as a precautionary tool to hold more cash so as to reduce the possibility
of running into financial distress. Here again, using the trade-off theory, it is expected that, firms
that are highly leveraged will have high cash holdings. To this end, the relationship between the
26
level of cash holding and leverage is thus positive. However, taking leverage of firms as a proxy
for their ability to issue debt, the existing relationship then tends to be a negative one since firms
with high leverage, hold a lesser amount of cash (Ferreira & Vilela, 2004; D’Mello et al., 2008).
Analysing this relationship from the viewpoint of the pecking order theory, Jani et al. (2004)
explained that, since the issue of debt by firms is done only after they finish using up all retained
earnings for investment and repaid in the situation of an excess of retained earnings, the cash
holding of a firm falls when the level of investment surpasses retained earnings while the level of
cash holding actually increases when the level of investment goes below retained earnings. In view
of the agency theory, however, managers of firms prefer to hold an increased amount of cash when
the leverage of a firm is less (Ferreira & Vilela, 2004).
Leverage, as predicted by theory thus suggests that its relationship with cash holding is uncertain.
By this, the predictions of the three theories propose an association which can either be negative
or positive.
Cash Flow: According to Ferreira and Vilela (2004), having a Cash Flow in a firm is equivalent
to having a ready and an alternative source of available liquid assets which reduces the necessity
to hold very high levels of cash. Using the trade-off theory, Ferreira and Vilela (2004) predicted
an inverse relationship between the Cash Flow of a firm and the amount of cash holding of that
firm. Thus a firm with high Cash Flow all things being equal will hold very low cash level judging
from the predictions of a trade-off theory. On the other hand, the relationship between Cash Flow
and the amount of cash held by a firm using the perking order theory indicates a positive
relationship. By this argument, firms with high Cash Flow will thus hold most of this Cash Flow
as cash. Deloof (2003) iterates that, if firms finance new investments using liquid reserves such
as cash and marketable securities, then since they will keep Cash Flows in the form of liquid
reserves to be freed up easily when needed, higher Cash Flow will, therefore, mean higher liquid
27
reserves. Garcia-Teruel and Martinez-Solano (2008), refers to this phenomenon as the financing
motive to holding cash. Deloof (2003), complements this saying, maintaining higher Cash Flows
can also be interpreted as a precautionary move towards shortfalls in future Cash Flow in the course
of operations.
From the ensuing review and analysis, since the trade-off theory forecasts an inverse relationship
between Cash Flow and the pecking order theory predicts a direct one, the expected relationship
or impact of Cash Flow on the level of cash holdings, therefore, remains uncertain.
Cash-flow volatility: Volatilities in Cash Flows implies the possibility of shortages in possible
future cash of firms. Firms with high uncertainty in their level of Cash Flow tend to keep higher
levels of cash in an anticipation of future Cash Flow shortages (D’Mello et al., 2008; Bates et al.,
2009). Thus, by the trade-off theory, it is expected that a direct relationship must exist between
Cash Flow volatility and the level of cash holdings.
The shortage in the Cash Flow for a firm can have long-term consequences on the firm’s
investment opportunities. The motive for the amount of cash holding due to this possibility will,
therefore, be highly related to the precautionary motive for holding cash. There exists evidence
supporting the fact that firms that experience shortfalls in their Cash Flow do sacrifice valuable
growth opportunities. Ozkan and Ozkan (2004) argued that firms which have ever experienced
shortages in their Cash Flow will be prepared to rather let go of the investment opportunity open
to them than react to cash-flow shortages by changing the discretionary timing of that investment.
Also, if a firm continues to experience shortfalls in its Cash Flow due to their high Cash Flow
volatility, the cost of obtaining external funds tends to be higher. They hence tend to keep more
cash reserves with the intention of relaxing their reliance on these costly external debts and equity
in financing. From the perspective of the trade-off theory, there exists a positive relationship
28
between the level of cash holding and the volatility in Cash Flow. According to Opler et.al. (1999)
and Jani et al. (2004), the relationship existing between the volatility in Cash Flow and cash
holding is however unclear. Further, according to D’Mello et al. (2008), the volatility in Cash Flow
for a firm indicates to a large extent the expected cost of financial distress. Similarly, Garcia-Teruel
and Martinez-Solano (2008) added that while financial distress may increase the level of cash
holding of firms as a way of reducing their default risk, these firms or those most likely to be
financially distressed may very well have less liquidity. Thus, to be financially distressed as a firm
means to be unable to meet payment commitments and hence it is logical to conclude that
financially distressed firms would be without a capacity to accrue cash. In line with these
arguments, therefore, the relationship between the level of cash holding and Cash Flow volatility
of a firm remains indeterminate.
Investment and Investment Opportunities: The volume of Cash Flow generated as a result of both
short term and long term activities in investment impacts the level of cash for firms. The
cumulative change in the cash position through investments of a firm primarily manifests as a
result of the gains and/or losses accruing from the financial markets. Further, subsidiary changes
in cash as a result of investments in such capital assets like plant and equipment and investments
in research and developments influence the level of cash holding of firms. Particularly the
discussion about research and development investments relates well to that for capital
expenditures. According to D’Mello et al. (2008), investments in research and development can
be used as a proxy for the measurement of growth opportunities or the cost of financial distress.
Opler et al. (1999) in examining the determinants and implications of corporate cash holdings
contended that the existence of information asymmetry is of most importance in determining the
impact of research and development on corporate cash holding behaviour. Thus, in situations
where asymmetric information is deemed crucial, a shortfall in Cash Flow may result in a reduction
29
of investment which will lead to an increased cost of financial distress. It is for this reason expected
that firms with a higher cost of financial distress as a result of high expenses on research and
development will hold increased levels of cash. This stance as argued from the static trade-off
theory point of view stands to reason that there exists a positive relationship between investment
and the level of cash holdings (Bates et al., 2009). Alternatively, the pecking order theory
hypothesises a negative relationship between investment and cash holdings as firms tend to
accumulate less cash when they spend more on investments (Opler et al., 1999).
Similarly, the presence of opportunities in investment impacts the level of target cash holding of
firms. According to Alles, Lian, and Xu (2012), investment opportunities for firms relates to the
level of target cash held positively as a result of different reasons. According to them, the
opportunity cost of a shortage in the level of cash is high when a firm has investment opportunities.
This is because these firms tend to forego lucrative ventures if they lack immediate cash in order
to respond speedily to such opportunities due to market competition. Delays in ceasing such
opportunities could imply a perpetual foregoing of these opportunities (Baskin, 1987).
Also, holding enough cash readily available could reduce drastically transaction costs connected
with lengthy processes involved in accessing external capital market for funds when opportunities
for investment are eminent (Alles et al., 2012).
2.6 Determinants of Cash Flow in the Insurance Industry
When investigating the determinants of Cash Flow for a firm, it is essential to consider all the
various activities that contribute to the overall cash position of that firm. For the insurance industry,
the generation of Cash Flows can be realised through activities in underwriting, financing and
investment choices, capital management and even through risks management (Born et al., 2014).
30
This assumes that Cash Flow generated within the industry dynamically interrelates with these
activities and consequently any modelling of Cash Flow essential to forecasting and managing
future Cash Flows must recognise this dynamic process by which financial, investment and
underwriting risks are generated. In their empirical study of Cash Flow risk management, Born et
al. (2014), modelled Cash Flow using a Dynamic Factor Model which recognises the dynamic
process of cash generation is insurance firms. According to them, the net Cash Flow of an
insurance firm goes through a generation process which incorporates activities in financing,
investment and underwriting as well as risk management. This approach is particularly unique as
it combines underwriting risks which are peculiar to insurance firms with financial and investment
activities which are common to both financial and non-financial institutions while incorporating
macroeconomic variables as well.
Unlike other previous studies related to forecasting cash and Cash Flow management (Stock &
Watson, 2006; Forni, Hallin, Lippi, & Reichlin, 2005; Jang, Park, & Lee, 2011; Geweke, 1977),
the study of Born et al. (2014), applied a novel DFM (FAAR) approach and focuses on analysing
the health of insurance firms using various Cash Flow ratios in a dynamic interaction to forecast
Cash Flows of insurance firms while incorporating macroeconomic variables. The findings in this
study present a novel forecasting model for each insurance firm depending on its size within the
industry.
2.7 Parent Disciplines: Accrual and Cash Accounting
In an effort to set a foundation for this study, literature is reviewed on two broad disciplines in
order to present a bigger picture and establish gaps in previous research. Literature, as viewed from
a broader perspective relating to Cash and Accrual Accounting, is thus reviewed and later
31
narrowed to an immediate discipline. This section presents an evaluation of two parent disciplines
considered as the primary basis for the preparation of financial statements.
2.7.1 Accrual Accounting
According to the International Accounting Standard Board (IASB) (2001), the primary objective
of financial statements is to make available information regarding the financial position,
performance and the variations in these measurements over time in order to enable users of this
information to make sound economic decisions. Accrual accounting is one of the generally
accepted conventions in accounting recommended by the International Accounting Standard
Board (IASB, 2001) for the preparation of financial statements.
The accrual accounting convention to reporting financial information identifies and reports
accordingly revenues and expenses for accounting periods for which they occur irrespective of
when cash is received for the revenue or when cash is paid for the corresponding expense incurred
(Keown et al., 2005; Elliott & Elliott, 2007). Thus, transactions under this convention of financial
reporting are divided into periods in which the economic activity occurred but not automatically
the same period in which Cash Flows of these transactions are related. Financial information
reported using accrual accounting consequently provides superior information not only on receipt
of cash and payment of expenses but also on the continuing ability of a firm to generate future
Cash Flows. Financial information reported under this basis, therefore, furnishes users with
historical transactional information involving cash the receipt and payment of cash as well as
information on future financial obligations of cash payments and cash benefits (IASB, 2001; Elliott
& Elliott, 2007). The derivation of net incomes or earnings, assets and liabilities and accounting
for historical costs under the accrual accounting convention, however, rely on certain principles
32
such as revenue recognition, matching principle in addition to historical cost conventions and the
going concern principles which are beyond the scope of this study.
2.7.1.1 The subjectivity of accrual-based accounting information to cash-based ones
In accrual-based accounting reports, information such as earnings has the potential of being higher
subjective relative to Cash Flow measurements. Estimations of future Cash Flow and the valuation
and allocation of deferred past Cash Flows that are characterised with the accrual-based financial
accounting are often subject to the discretion and estimation of management (Dechow, Richardson,
& Sloan, 2008). Estimations made under the accrual-based convention may, however, encompass
several and complicated assumptions concerning future events and these make critics of this
convention of accounting information reporting argue the inability of inexperienced users to
comprehend fully information presented therein (Athukorala & Reid, 2003). Contrary to this
approach, the information presented using cash accounting is more objective and simple in nature
as it presents information on only payments and receipts of cash as they occur.
Other arguments against the use of accrual-based accounting also make clear the possibilities of
income manipulations or earnings management by firms in the course of allocating periodic Cash
Flows. According to Graham, Harvey, & Rajgopal (2005), earnings management refers to the
intentional structuring of accounting practices or transactions in an attempt to manipulate the
reporting of financial information to deceive stakeholders on their perception of the real economic
performance of a firm. Prior empirical literature examining a large cross-section of companies
shown that firms overstate the value of their earnings before equity offerings (Erickson & Wang,
1999; Rangan, 1998; Teoh, Welch, & Wong, 1998). These issues and many others not stated here
relating to the subjectivity of the accrual-based accounting reporting notwithstanding does not
provide necessarily an absolute superiority of the cash-based accounting over the accrual-based
33
one. For instance, cash information about the dates of payment and receipt of cash reported in
cash-based accounting can also be manipulated by choosing favourable policies in order to classify
current items as capital one and vice versa (Diamond, 2002).
2.7.2 Cash accounting
The principle governing cash-based accounting reporting identifies only cash transactions
involving, for example, the cash payments for expenses incurred and the receipt of cash as income
(Birt, Chalmers, Beal, Brooks, Byrne & Oliver, 2008). With this convention, earnings are recorded
as pertaining to a given accounting period only when cash is received and likewise expenses
documented with the payment of cash. Cash-based accounting convention to financial reporting
as noted by Elliot and Elliot (2007), stands to be more prudent as compared to accrual-based
accounting as it only accounts for Cash Flow when they are realised devoid of any form of
anticipation of the occurrence of Cash Flows. In view of the nature of this method, very few
assumptions are required in cash accounting reporting as cash financial transactions reported can
be checked and verified with much ease as opposed to accrual accounting. As a result, the
requirements for the disclosure of accounting policies such as the methods for calculating
depreciation are fewer with this method (Elliott & Elliott, 2007). Most information captured in
accrual-based financial reporting often becomes difficult to comprehend by policymakers,
financial decision makers, credit rating agencies, the media and most especially the general public
(Athukorala & Reid 2003). Conversely, cash-based reported financial information is relatively
more simply comprehensible especially by unsophisticated users of this information.
2.7.2.1 Objectivity of Cash Flow information to the accrual-based information
Arguably, cash accounting convention to financial report reporting is more objective than accrual-
based accounting since it lends itself to less subjectivity seen in through management judgments
34
in accrual accounting in the determination of values reported in financial statements (Athukorala
& Reid 2003; Dechow et al., 2008). The value of the net income that is reported in the financial
statement of firms under the accrual-based accounting lends itself to high subjectivity as the
assumptions and subsequent estimations may be greatly erroneous owing to biasedness of
management (Elliot & Elliot, 2007). This assertion is further strengthened through the prudence
concept which biasedly recommends under the accrual-based accounting that, in the presence of
uncertainty, firms must avoid overstating assets and gains along with avoiding the understatement
of liabilities and losses (Elliott & Elliott, 2007). Financial information reported using cash
accounting thus to a large extent based on facts about the performance of a firm without the
influence of management preferences. The Financial Accounting Standards Board (FASB) posits
that detailed disclosure of Cash Flow data using cash accounting will enable users of this
information to better assess the amount, timing and uncertainties of future cash-flows (Casey &
Bartczak, 1985). Users of financial information reported using cash accounting are thus placed in
a better position to evaluate the ability of firms to generate future Cash Flows in order to meet
future obligations such as dividend payments and payment for genuine claims in the case of
insurance firms (Elliott & Elliott, 2007). Also, the objectivity present in reported Cash Flow
information assists in the comparison of firms’ performance and overcome differences in
accounting treatments that may arise in accrual accounting (Chotkunakitti, 2005).
Information on the current and historic Cash Flow of firms is very crucial and forms the foundation
for future forecasting of Cash Flows. This informs users to assess the accuracy of past Cash Flow
forecasts in validating the applicability of past Cash Flows in significantly predicting future Cash
Flow and also thoroughly assess the relationship between changes in the net Cash Flow of firms
and their profitability as established in previous studies (Barth, Cram, & Nelson, 2001; Bowen,
Burgstahler, & Daley, 1986; Waldron & Jordan, 2010). Table 2.1 summarises some differences
35
between cash and accrual accounting conventions to accounting reporting as developed in extant
literature

2.8 Empirical Literature Review on Cash Flow Risk of Firms
The availability of cash in any business, small or large is a vital and a continued crucial requirement
for the survival of that business (Ryu & Jang, 2004). The importance of cash-flow as a crucial need
for many businesses in a variety of industries have been discussed in extant literature over the
decades (Casey & Bartczak, 1985; Almeida et al., 2004; Alti, 2003; Born et al, 2014). According
to Beck, (1994), a firm must close if it runs out of cash even though it might be operating at a
profit. This is because bills are paid not against income but cash, and this is critical every day and
distinguishes between successful operations and closure. Users of financial statements in addition
to regulators of publicly reported financial accounting data, therefore, need on regular basis
detailed information on the current operating Cash Flow of firms. This reason necessitated a call
by FASB in November 1987, for all financial statements to include a statement of Cash Flows in
addition to the traditional income statement and balance sheet (Ryu & Jang, 2004) and this further
heightened the topic of Cash Flow hence Cash Flow ratios analysis as they provide additional
information and understanding in measuring the real operational position of a business.
Analysts in business have identified poor Cash Flow management as the foremost reason for
failure in businesses (Caux, 2005). Effective management of Cash Flow is, therefore, one key
aspect of financial management in planning future cash requirements of businesses in today’s
world of increasing economic and financial crisis. The primary motive for Cash Flow forecast,
therefore, is to identify in advance potential shortfalls in the balances as it serves as an “early
warning system” (Bodunrin, 2016).
Just as the banking industry, insurance plays a crucial role in modern financial systems. In order
to perform their role effectively, insurance firms must be financially safe and be perceived as such.
One of the most important guarantees of this is the economic value of assets to be significantly
more than liabilities. Due to the recent financial crisis, however, there is the need for a second type
37
of cushion, the “liquidity” to cover unexpected cash outflows. This is because, a firm can be
solvent, holding economic assets exceeding liabilities on an accrual accounting basis, but still die
suddenly if its customers and other stakeholders lose confidence in that firm (Elliott, 2014).
Various estimating methods for assessing a firm’s financial health and the likelihood of its
financial distress have evolved over the decades. Jang, Park, and Lee (2011), used the comparable
approach to Cash-Flow-at-Risk (CFaR) to analyse Cash Flow data from publicly listed U.S.
restaurant firms from 1988 to 2007. In Ryu and Jang (2004), the performance of commercial and
casino hotel companies were measured using Cash Flow ratios and traditional financial ratios from
income statements and balance sheets. According to this study, traditional ratio analysis often fails
to make known severe liquidity difficulties that may result in the insolvency of firms. Results
indicate that traditional ratios produce different outcomes from Cash Flow ratios in liquidity.
Similar studies on firm performance stressed the importance of Cash Flow in predicting the
likelihood of insolvency (Almeida et al., 2004; Alti, 2003; Casey & Bartczak, 1985). According
to Guth & Sepetys (2001), the risks to a firm are evident in shocks to expected Cash Flow which
in turn spells the survivorship of the firm depending on the adequacy of cash available. Despite
the fact that Cash Flow risks pose a substantial danger to most companies, the detection and
management of such risks are not a common practice in most firms especially in the insurance
industry of Ghana. This current study, therefore, applies the novel FAAR (DFM) modelling
employed by Born et al. (2014) to forecast Cash Flow of Ghanaian insurance firms. This study is,
however, different from existing literature as it goes beyond forecasting future Cash Flow to
further determining insurance activities and factors that significantly impact Cash Flow. The study
also investigates the impact of management practices of insurers in underwriting, financing and
investment, risk management and capital management on Cash Flow. Thus, to the best of the
writer’s knowledge although there are numerous extant literature on Cash Flow risks, these studies
38
use various models to forecast future Cash Flow and measure future Cash Flow risks without
necessarily studying the relationship between factors impacting Cash Flow and Cash Flow levels.
This current work, therefore, goes beyond what has been documented to further explore the
relationships between identified individual factors and insurers’ Cash Flow as well as the
relationship between some management practices of insurers and their Cash Flow.
2.9 Chapter Conclusion
Included in this chapter is a demonstration of the significance of future Cash Flows prediction as
well as a review of literature pertaining to some determinants of Cash Flow and cash holding
practices of firms. The chapter also reviewed literature on some grounding theories regarding cash
holding practices of corporate entities and highlighted two parent disciplines specifically accrual
and cash accounting principles regarding the reporting of financial accounting information.
Issues in prior research were also identified and the significance of this current research was
established based on current gaps identified. The ensuing chapter develops the research design and
methodology to test hypotheses and provide answers to the research questions posed.

CHAPTER THREE
METHODOLOGY
3.1 Introduction
In this chapter, the various tools and estimation procedures applied in achieving the set aims and
objectives are clearly identified and explained. It also outlines the scope of the study and the
various sources of data required for analysis and accomplishment of the research objectives. This
chapter further specifies and justifies the econometric model adopted and clearly explains the
variables used in the models employed. Thus, the chapter lays strong emphasis on the data sources
and their scope, the conceptual and functional economic models employed as well as the estimation
procedures employed in the choice of methodology and finally the conclusion.
3.2 Research approach
The two generally main ways of carrying a research study involve the deductive and inductive
approaches. According to Sauders, Lewis, and Thornhill (2009), the deductive approach, allows a
researcher to develop a theory and hypothesis (hypotheses) and design a research strategy or
strategies to test those hypotheses. In their view, deductive approach to research remains dominant
in the natural sciences as a basis for explaining and proving laws and permit the anticipation of
phenomena as they predict their occurrences and allow for their control.
Inductive approach, on the other hand, starts with the researcher collecting data and developing a
theory as a result of the data analysis. This approach supports the study of human behaviours based
on context. This approach thus allows a researcher to decipher human understandings and
behaviours within their social environment (Ghauri & Grønhaug, 2005). This study, however,
benefits from the rich qualities of a deductive approach to research as it seeks to test hypotheses
around the determinants and factors influencing the Cash Flow levels of non-life insurance
40
companies in the insurance industry of Ghana and finding a suitable model to project and forecast
the net Cash Flow level of an insurance firm for a one-time future period using relevant data.
3.3 Research Design
This section outlines the plan that guides the researcher in the organisation of the research activity.
The methodology regarding what, where and how to gather relevant data and analyse it so as to
achieve the preconceived purpose of the research is outlined here. It is the detailed plan aimed at
guiding the researcher in the step by step organisation of the research activity of investigating a
given phenomenon. Thus the identification of a suitable methodology about what, where, when
and how to gather data and analyse it are defined herein (Easterby, Thorpe, & Lowe, 1991).
Bryman and Bell (2003), indicated that data collection methods and design of a research should
be aligned with the paradigm adopted such that they are consistent with each other. According to
them, there are three main classifications of business research which are exploratory, descriptive
and explanatory research. This current research employs the rich qualities of an explanatory
research by extending findings of extant literature in investigating determinants of Cash Flow in
the cash holding practices of insurance firms as well as predicting future Cash Flows of non-life
insurance firms in the Ghanaian insurance industry using accounting information.
Neuman (2006), explained explanatory research to be a type of research that builds on existing
research in explaining an existing phenomenon in order to validate or reject predictions or
explanations given or test an existing theory or extend it. This explanation fits into this study as it
extends previous research by examining the predictability of future Cash Flows using past financial
data. This approach falls within the positivist paradigm as it is most suitable for examining cause
and effect relationships predicted by theory to describe an observed phenomenon (Neuman, 2006),
using a quantitative approach.
41
The study used pooled ordinary least squares (OLS) method to develop multiple regression models
to identify determinants of Cash Flow in the insurance industry. Further, a novel DFM (FAAR)
Model as used in Born et al. (2014), is employed to empirically forecast future Cash Flows in order
identify and manage possible Cash Flow risks.
Statistical techniques were applied to sampled data in order to test hypotheses and analyse findings.
Conclusions and inferences were drawn with reference to relevant literature. The overview of the
design is presented as in Figure 3.1.

Figure 3.1: Research Design Overview
3.3.1 Research Methodology: Quantitative versus Qualitative.
The two main research methodologies guiding the conduct of every research are the qualitative
and the quantitative approaches to research (Bryman & Bell, 2003; Neuman, 2006). This section
42
contrasts and compares the qualities of both orientations and selects the most appropriate
methodology suitable to achieve the set objectives in this study.
Qualitative research as explained by Neuman (2006), relies on interpretive or critical social science
in describing various influencing factors of a social phenomenon as well as complexities associated
in an iterative and a nonlinear research path within a specific historical context.
This research path largely emphasises inductive processes between existing theory and research in
an attempt to build further theories (Bryman & Bell, 2003; McMurray, 2008). According to
McMurray (2008), qualitative research stresses on descriptive words and their implicative images
in the collection and analyses of data instead of numerical information. These type of research
recognises individual perspectives regarding a research matter, expresses intimate participation of
the researcher as well as an interpretation of the theme within the particular context of study
(Neuman, 2006). Nonetheless, the values, beliefs, preconceptions or experience of these
researchers have to a large extent the potential of impacting the credibility or reliability of these
studies.
Alternatively, qualitative research concerns with measuring variables with great precision and by
employing a deductive approach, test hypotheses in a linear path to explain a phenomenon
(Neuman, 2006). By this, quantitative studies seek to lessen the human factor present in qualitative
studies by emphasising the need for objectivity in the conduct of a research. The methods selected
in a quantitative study bases on standardised data sets and numerical analyses highly statistically
based (Bryman & Bell, 2003; McMurray, 2008). Thus, quantitative research supports minimal
researcher involvement as much as possible in order to give room for replicability and
generalizability in different settings aside the confines within which the study was piloted. These
studies are cross-sectional, longitudinal, correlation and survey studies (McMurray, 2008).
43
Quantitative studies by their approach seek to offer fresh intuitions to existing theories or
extending to new settings as they formulate and test relationships using standardised numerical
evidence assigned to variables identified (Neuman, 2006).
In this study, the researcher makes use of quantitative methodology to research as it is most suited
to and aligned with explanatory research to examine as well as provide empirical evidence to the
extent to which historic Cash Flow data combined with latent variables related to insurance
activities help forecast future Cash Flow of insurers.
3.4 Conceptual Framework for Prediction Models Development
This section describes the conceptual framework aligned with a quantitative methodology to
develop predictive models. According to Bryman and Bell (2003), the concepts around a research
are the ideas which are the very foundations of theory. The deductive approach to research used
by quantitative researchers start with concepts and thereafter formulate measurement procedures
to capture the concepts in a quantitative form to link the abstract constructs with numerical
evidence about empirical reality (Neuman, 2006). After getting these concepts operationalized,
they can be then classified as either dependent variables which respond to changes in other
variables and for which the researcher needs explanations to or independent variables or predictor
variables which explain variations in the dependent variables or the phenomenon that needs
investigation (Bryman & Bell, 2003; McMurray, 2008; Saunders et al., 2003)
Extant literature used numerous statistical approaches in developing predictive models for future
Cash Flows of firms. Many of such studies made use of the least square method to develop simple
or multiple regression models to predict Cash Flows. This method strives to fit observed data to a
model that predicts them by reducing to the barest minimum the sum of squared errors between
the actual observed data and the predicted data (Field, 2009).
44
Previous studies examined the relative predictability of earnings and operating Cash Flows in
forecasting future Cash Flows. These studies employed regressing analysis by using current
operating Cash Flows as proxy for future ones by considering period-lagged earnings or Cash
Flows or a combination of period-lagged Cash Flows with accruals (Barth et al., 2001;
Chotkunakitti, 2005; Kim & Kross, 2005; Arthur & Chuang, 2006; Farshadfar et al., 2008). Some
previous studies also assumed random walk models where Cash Flows in the current period is
assumed to persist into both the current and future periods (Barth et al., 2001; Yoder, 2006).
In line with these ideas (Barth et al., 2001; Arthur & Chuang, 2006; Cheng & Hollie, 2008;
Chotkunakitti, 2005), this study employs ordinary least squares methods to develop multiple
regression models to investigate and statistically test hypotheses around the determinants of Cash
Flow in the insurance industry using past values of Cash Flow. In 2006, Manning and Munro
pointed out that, ordinary least square method is most suitable when the main objective of a
research is to investigate causal relationships between variables having a dichotomous nominal
scale, ratio or interval scales and also satisfies normality assumptions.
Additionally, this study also adopts the dynamic factor modelling approach applied by Born et al.
(2014) by augmenting all latent factors related to insurers’ activities in underwriting, financing
(investing), risk management and capital management in the presence of macroeconomic variables
to model the dynamic interactions of all these activities to forecast future Cash Flows of firms in
the insurance industry of Ghana.
It is important to add that, although the models developed in this study builds strongly on the
approach used by Born et al. (2014) and Wen, Lin, Born, Yang, and Wang (2018), this study also
goes beyond forecasting future Cash Flow to also study the relationships between identified
variables related to insurers’ activities in underwriting, financing (investing), risk management and
capital management and Cash Flow. Results presented, therefore, shows relationships between key
45
variables related to activities in insurance and their effect on Cash Flow levels aside augmenting
these variables in a dynamic structure to predict future Cash Flow as applied in Born et al. (2014)
3.5 Research population
The population for this study focusses on the insurance sector of the financial services industry in
Ghana. Specifically, in a quest to manage Cash Flow risks, secondary quarterly data from financial
statements of non-life insurance companies in Ghana was extracted. By this, Cash Flow data
relating to underwriting, financing or investment, risk management and capital management in
non-life insurance companies of Ghana were considered. As earlier stated, data was hence obtained
taking into consideration all the 25 non-life insurance companies in Ghana (NIC, 2015).
3.6 Sample and Sampling Technique
In order to apply pooled ordinary least square and dynamic factor models for a comprehensive and
explicit examination of Cash Flow management by insurers, time series financial data of non-life
insurance business pertaining to firm-level variables such as capital, liabilities and assets and other
variables relating to activities in underwriting, financing and investing, risk management etc. were
collected and analysed empirically. Information relating to insurers’ assets, liabilities, capital
(equity), Cash Flows, investments, income statements etc., from the first quarter of the year 2007
to the fourth quarter of the year 2015 was extracted into Microsoft Excel worksheets for feasible
time series modelling with sufficient observations over periods.
The study applied purposive sampling technique to obtain feasible data of insurance firms. Thus
in order to gather sufficiently relevant data for all firms within the study period (2007 – 2015), the
study selectively chose firms with available non-negative assets and premiums written in each year
for at least seven (7) years (Barth et al., 2001; Yang, 2000; Chotkunakitti, 2005). This period
46
(2007-2015) particularly had been considered for data collection due to the new insurance act
(ACT 724) which prohibited the forming and existence of composite insurance companies and
thereby calling for the separation of existing ones for a better regulation and supervision of
insurance business in the country. Secondly, the time period selected also provides recent time-
series observations to capture the current financial climate of the economy marking the major
change in regulation (enactment of the 2006 ACT). The study period ended 2015 since this
particular year provides data for the most recent financial data available for the study. Data relating
to the financial activities of these firms were obtained from the National Insurance Commission as
well as individual insurance companies in Ghana. Furthermore, in order to incorporate macro
factors relating to economic growth into the analysis, quarterly interest rates, inflation rates,
unemployment and GDP growth rates were as well collected. These macroeconomic variables
were retrieved from AFDB (African Development Bank) Group (Africa Information Highway,
2017) and also the World Development Indicators (World Development Indicators, 2017)
The data collection and sampling procedure thus resulted in a sample of 21 non-life insurance
firms within Ghana with feasible and available data over the period sample period. The procedure
resulted in this number due to the fact that, some of these firms came into existence barely a few
years ago relative to the sampling period under consideration.
Previous studies investigated differing research period lengths, ranging from two (2) to twenty
(20) years. This current research period is at par with Chotkunakitti (2005) and Ebaid, (2011) while
exceeding other previous studies like Arthur and Chuang (2006) and Quirin, O'Bryan, Wilcox, &
Berry (1999). The length of 9 years period as examined in this research is thus also acceptable.
With this sample, multiple linear regression and principal component analysis are conducted to
apply ordinary least squares panel analysis for the entire industry and dynamic factor time-series
47
models for each of the sample firms over the nine (9) year (36-quarter) time period under
consideration to make an inference from the empirical results.
3.7 Data collection
In obtaining data for this study, secondary data relating to firms’ Cash Flows were relied upon.
These data are quantitative in nature and based on financially accepted information presentation
standards. For the purpose of this study, financially accepted information presentation standard
refers to the International Financial Reporting Standards (IFRSs) adopted by Ghana as of 1 January
2007 in place of the Ghana National Accounting Standards, for all financial and non-financial
companies.
3.8 Specification of the Model
In selecting a methodology, this study employed linear regression models to determine factors
impacting Cash Flow of insurance forms. The study adopted variables identified in the study of
Born et al. (2014) as key variables in determining Cash Flow of insurance firms. The study also
used a novel FAAR (DFM) model (Born et al., 2014) to dynamically model the interrelations
between core insurance activities and their dynamic relations in order to forecast future Cash Flow
and identify possible Cash Flow risks.
Thus, the ability to accurately forecast future Cash Flow with minimal error will serve a
foreknowledge in identifying any solvency risks inherent and thereby manage those risks as
applicable.
3.8.1 Correlation Evaluation
In order to ensure the existence of a relationship between dependent and independent variables,
the study tested the association between these variables prior to the conduct of a regression (Collins
48
& Hussey, 2003). Field (2009), stressed that in order to make the regression model generalizable,
there should not be a perfect linear relationship between two or more of the predictor variables.
The presence of this condition will bring about the problem of multicollinearity leading to a
difficulty in evaluating the contribution of each variable in the model. According to Field (2009),
multicollinearity exists when the coefficient of correlation for any two pair of predictors exceeds
0.90. Pearson correlation was thus conducted to assess the size and direction of the association
between the variables used in the study.
3.8.2 Regression Analysis
In order to determine factors that influence the Cash Flow level of an insurance firm, this study
identified variables that contribute to Cash Flow of insurance firms. These variables were
identified as either dependent or independent variable. Dependent or response variables respond
to changes in other variables referred to as independent variables or predictors (Saunders et al.,
2003; McMurray, 2008). Dependent variables represent variables to which a researcher seeks
explanations while independent variables are the ones that provide explanations to the
phenomenon being examined. They are the predicted variables in a model. In this study, multiple
regression models were developed to seek explanations to Cash Flow of firms. The regression
model developed considered predictors relating to the core activities of insurers. These variables
were combined in multiple linear regression models using ordinary least square estimation method
to determine Cash Flow. Previous studies investigated mostly determinants of cash holdings of
firms and the predictive strength of operating Cash Flows as well as earnings in predicting future
Cash Flows by regressing current operating Cash Flows on period-lagged operating Cash Flows,
period lagged operating Cash Flow combined with accruals and period-lagged earnings (Barth et
al., 2001; Chotkunakitti, 2005; Arthur & Chuang, 2006; Farshadfar et al., 2008). Some previous
49
studies also considered the random walk model which suggests that current Cash Flow levels
persist into both current and future periods (Barth et al., 2001; Dechow et al., 2008; Yoder, 2006).
Consistent with prior studies, this study measures the determinants of Cash Flow using identified
observed variables as specified in equation 3.1.
Multiple linear regression has been highly recommended by some researchers to test theory
(Studenmund & Cassidy, 1987). This method is most suited for testing causal relationships
between variables which are dichotomous nominal scale, interval or ratio and satisfy normality
assumptions (Manning & Munro, 2006). The generic regression equations used in this study to
evaluate the relationship between Cash Flow and its predictors is as stated in equation 3.1.

Where β0 is the value of Cash Flow from the model when all predictors are zero, βi for i starting
from 1,2,…,10 are the regression coefficients for the various predictors and ε the error term. The
predictors remain the same as described in Table 3.1.
3.8.3 Principal Component Analysis
In order to identify latent factors which are unobserved but related to insurers’ activities in
investing, underwriting and risk management at the firm level, this study performs an analysis of
principal components to extract these factors (Born et al., 2014). Similarly, latent variables
relating to macroeconomic variables as well as industry-specific variables such as regulatory
requirements and underwriting cycles were also identified through principal component analysis
50
denoted, Ft, through observed (Xt) variables identified in insurers underwriting, investment and
financial choices, capital and risk management activities. In terms of the choice of observed
variables Xt, this study followed the analysis of Born et al. (2014) and categorised variables mainly
pertaining to (1) capital management, (2) financial (investment) management, and (3) risk
management. Furthermore, variables capturing insurers’ (4) firm characteristics, (5) underwriting
activities, in addition to variables relating to the macroeconomic environment, were chosen. Each
category of variables depicts different risk factors of an insurance firm.
3.8.4 Dynamic Factor Modelling
Dynamic Factor Modelling (DFM) is one of the most frequently used methods by policymakers
and economic researchers while considering key macroeconomic variables for the purposes of
forecasting. According to Born et al. (2014), DFM was developed by Geweke in 1977 and further
revised by Giannone, Reichlin and Sala (2004) and Watson (2004). DFM is an extension of factor
analysis and has the capability to depict the time-varying nature of relationships by taken into
consideration dynamic patterns. Following Born et al. (2014), this study applied Factor Augmented
Autoregressive (DFM) modelling to forecast future Cash Flow of insurers at the firm-level taking
into consideration macroeconomic variables and firm-specific factors.
The choice of methodology is additionally suitable because its application can resolve the problem
of multicollinearity when considering too many variables in multiple regression models. Besides,
there exists the possibility of structural changes as a result of incorporating macro business cycles
as well as underwriting cycles. As suggested by Rochet & Villeneuve (2011), there exists a non-
monotonic theoretical impact of investment management and risk management decisions on the
level of Cash Flow within a firm. Further, and as suggested by Fairley (1979), the expected
earnings of an insurance firm is made up of profit margin as a result of underwriting and returns
51
from investment activities. This important highlight, therefore, points to the need of considering a
model that utilises the interactions between investment, underwriting and other actions of the firm
that generates or influences the Cash Flow for that firm.
DFM application hence enables the study of Cash Flow in the presence of underwriting cycles to
explicitly depict embedded structural changes while modelling theoretically factors and
empirically analysing observed data (Belviso & Milani, 2006). This study, therefore, considers a
model that makes use of all variables relevant to the generation of Cash Flow in a dimension-
reduction technique, incorporating more information in the calculation and hence depicting the
dynamic patterns of Cash Flows for an insurance firm.
By applying the factor forecasting model proposed by Stock and Watson in 2005 (Born et al.,
2014), the latent factors influencing the Cash Flow of a firm were constructed using predictors in
a dynamic structural equation of the form:
Xt = ΛFt + et (3.2)
Where Xt represents the observable variables, Ft is the estimated unobservable latent factors, Λ
representing the factor loading matrix and et being the error term. Stated differently, the variable
F explains variable X through the estimation of factor loadings with e as the error term in the
estimation. Specifically, Ft comprises both industry and firm-level factors. Firm-level factors are
latent variables associated with activities in underwriting, risk management, investing and
financing by insurers. Industry-level factors comprise latent variables related to macroeconomic
variables such as growth rate, interest rate, unemployment and inflation and industry-specific
variables, such as regulatory requirements and underwriting cycles. The factor loading matrix (Λ)
thus captures the dynamic interactions in Xt which explicitly describes observed insurance
underwriting and investment asset allocations. In total, the dynamic interactions between
underwriting, financial and investment asset allocation activities in the presence of
52
macroeconomic and firm-specific variables are captured in equation (3.2) based on dynamic factor
modelling.
Following Born et al. (2014) and applying FAAR (DFM) model, therefore, this study distinguishes
itself from other previous studies as the FAAR model does not necessitate strong assumptions on
the objective function. Thus, the DFM model applied in this study avoids strong assumptions such
as firm value maximisation or total cost minimization that are associated with profit and cost
efficiencies discussed in previous literature (Cummins & Weiss, 2000; Cummins & Xie, 2008).
Using the dynamic Cash Flow model, a Factor-Augmented Autoregressive Model is then
developed after integrating into it the Cash Flow generating process, as an equation by allowing
for cross-sectional characteristics and time-series factors (Born et.al., 2014). The model in
equation (3.3) is applied to depict how Cash Flows are revealed after simultaneously accounting
for the abovementioned interactions (Almeida et al., 2004). That is, by incorporating variables that
depict the principal components identified through significance comparison from the first step’s
analysis, future Cash Flows are predicted using the model in (3.3).
CF1t+1= α +γ 'Ft + Φ(L)CFt + ut+1 (3.3)
Where CF1t+1 is a one period forecasted Cash Flow at time t, Ft the estimated unobservable factors
from equation (3.3), (L)CFt being lagged Cash Flows at time t and ut+1 a random error for the
estimated dependent variables.
The conceptual Cash Flow model that guides the development of the dynamic model specified in
equation 3.3 is illustrated in figure 3.2. Thus, findings in this model estimation should indicate the
predictive ability of past Cash Flows on future Cash Flow.

Figure 3.2: Cash Flow model for future Cash Flow prediction
Based on this model set-up, the functional process is extended to a measurable system to capture
the dynamic interactions between activities and draw an optimal status for risk management,
investment and underwriting strategies. Particularly, by the use of PCA, which explains Cash Flow
variables relating to the principal activities of insurers, the generated significant PCs were picked
as the main factors and integrated into equation (4.5) along with an autoregression (AR) model to
forecast Cash Flows for the next period. In order to infer comparable results between firms, a
normalized CF variable of the form ln(CFi,t – min(CFi,t)) was constructed where, CFi,t is the Cash
Flow of firm i at time t and min(CFi,t) is the minimal Cash Flow among all observations. Since the
net Cash Flow for firms was negative for some time periods, a constant positive figure was added
to CF in order to make it positive to enable log normalisation. This is applied following the
conventional method used in the study of profit frontier in normalising key variables. The
normalised Cash Flow was then used as a key variable in an autoregressive Cash Flow model
together with estimated factors to predict future Cash Flow. Thus, the estimate �̂�T from equation
(3.2), along with equation (3.3) enables us to derive the empirical autoregression model (FAARM)
described as in equation (3.4):
𝐶�̂�FAAR, n𝑇 + 1⃓𝑇
= α̂ + 𝛾'�̂�T + Φ̂T(L)CFT (3.4)
54
In equation four (4), 𝐶�̂�FAAR, n𝑇 + 1⃓𝑇
represents a one period forecasted Cash Flow at time T + 1
using Cash Flow at time T. FAAR signifies a factor augmented autoregressive model with n
standing for an appropriate order for the AR process. α̂ is the estimated constant term, while 𝛾
and Φ̂T represent estimated coefficients.
3.9 Variables Construction and Expected Signs
In order to empirically carry out the application of dynamic factor modelling through the use of a
Factor-Augmented Auto Regressive (FAAR) models in forecasting and managing Cash Flow of
insurance firms, variables relating to capital management, firm characteristics, investment
(financial) management, risk management, underwriting activities as well as macroeconomic
factors were identified. The variables identified are then converted into ratios which measure to a
large extent the economic performance of financial firms. For the insurance industry, the Cash
Flow generated is primarily associated with their core activities. According to Rochet &
Villeneuve (2011), the Cash Flow generating process of an insurance firm can be described as a
function of underwriting profit which comprises expected profitability per unit of time as well as
the volatilities in primary earnings, the rate of return on investment portfolios as a result of
allocation of assets and hence the total investment cash inflows. Cash Flow for an insurance firm
also emanates from cash generated through risk management activities such as reinsurance and the
use of derivatives in managing risk. Firms’ activities in financing through the issue of securities
and financing costs corresponding to these financing activities have also been identified as the
determinants of Cash Flow for insurance firms. The variables constructed therefore considered all
the core activities of insurance firms relating to underwriting, financing or investment, risk
management, capital management and firm characteristics in the Cash Flow generating process.

3.10 Limitation to Methodology
One major limitation encountered in the estimation using this methodology is the availability of
enough data points so as to ensure generalisability. In order to estimate the individual time series
56
data models, there was the need for available data with enough observations for each firm.
Available time series data after the enactment of the 2006 ACT (ACT 724) which prohibited the
forming and existence of composite insurance companies, however, makes available an annual
time series data with only nine (9) observations (2007 – 2015). In order to deal with this limitation,
however, the study resorted to a quarterly time series financial data form the first quarter of the
year 2007 (2007q1) through to the fourth quarter of the year 2015 (2015q4). Although this study
would have employed a more frequent data (like a monthly data) or data over an extended period
of time, this is unavailable. This study, therefore, dealt with this challenge of insufficient data by
making use of quarterly financial data of non-life insurance firms within the context of Ghana for
the time series estimation and analysis.
3.11 Chapter Conclusion
The methodology in this study made use of quarterly time series data of 21 non-life insurance
companies in Ghana with feasible data. The methodology also incorporated economy-wide macro
variables which significantly affect the Cash Flow level of a firm. Observed variables relating to
insurers’ activities in underwriting, risk management, capital management, financial and
investment management were thus collected and latent factors extracted using principal component
analysis. These factors were further incorporated in a factor-augmented autoregressive process
with Cash Flow (CF) as the key variable at each stage of the estimation. The study made use of
principal components, as well as lagged Cash Flow values in a factor, augmented autoregressive
model to capture dynamic interactions between firms’ activities. All estimations were done using
Stata 13.1 Statistical Package.

CHAPTER FOUR
ESTIMATIONS AND DISCUSSION OF RESULTS
4.1 Introduction
This chapter presents the results as well as discuss the econometric estimations of the specified
model in chapter three. The chapter is organised into sections to reflect the steps involved in the
investigation process.
The presentation and analysis of the results, discussion of various estimates and extraction of latent
factors from observed variables to explain Cash Flow variations are done in this chapter. The
chapter towards the later part exhibits the forecasting power of the FAAR model and various
determinants of Cash Flow in the insurance industry. The chapter ends with a conclusion.
4.2 Industry Descriptive Statistics
In order to showcase how observed variables in insurers’ activities can be related to principal
components in the application of FAAR (DFM) modelling, this section presents a descriptive
statistics of the insurance industry as applied to the panel data. The analysis of the industry
variables presents the number of observations, mean and standard deviation for the various
variables measured. The statistics also present the minimum and maximum observations for all
variables of interest in order to present a clearer image of the industry in terms of its performance
in relation to the variables measured. Table 4.1 hence presents statistics on the variables used in
the model.
Table 4.1 presents two Cash Flow statistics to reflect actual observed net Cash Flow which is
negative for some observations and a log normalised net Cash Flow. The mean observation for the
not normalised net Cash Flow is GHC 7,615,073 with a standard deviation of 1.20E+07. Standard
58
deviation indicates the magnitude by which the Cash Flow of firms within the sample frame differs
from the mean value. This also gives a fair idea about the variations in CF of various firms in the
study. The values of CF ranged from a minimum of – GHC 1,785,030 to a maximum of GHC
9.28E+07. In order to take the natural log of the net Cash Flow for all firms, a constant positive
number (1,785,032) was added to all net cash values observed. CF (normalised) measured as
ln(CFit - min(CFit)) subsequently reported a mean average of 15.50828 and a standard deviation of
0.955158.

The mean average for the variable UW_R1 (underwriting gain/loss) among the sampled firms
stood at -0.02198. This value coupled with a minimum and maximum values extracted and
presented as -2.36207 and 0.557727 respectively reveal that non-life insurance companies on the
average were making underwriting losses (negative profits) over the period studied. This stands to
59
suggest that the revenue generated in underwriting falls below the associated cost of underwriting
and can only be supplemented with positive returns from other activities in either financial and
investment opportunities or capital management activities. This can also be associated with under-
pricing of insurance products (Undercutting of premiums to attract more clients).
Analysing Table 4.1, the mean of CF, however, shows that Ghanaian insurance firms on average
have positive Net Cash Flows as a result of continuing activities in business. This characteristic is
at par with the study of Chotkunakitti (2005) and Barth et al. (2001). In the category of
macroeconomic variables, the mean of Growth is 6.777778 which indicates a growth rate of
approximately 6.78% as against interest, unemployment and inflation rates of 18.14%, 3.38% and
12.44% respectively. Details on the other variables are as stated in Table 4.1.
4.2.1 Pearson’s Correlation Matrix
The relationship between the predicted and predictor variables as described in Section 3.6.1 is
presented in Table 4.2 using Pearson’s correlation coefficient matrix. The study used pairwise
exclusion of cases to ensure there was a corresponding variable for each observation. The result of
the correlation matrix revealed the existence of significant association among variables (p −
value < 0.05). The dependent variable CF shows significant correlation with variables Size, IT_R,
Sterm_R, ReInsAsset_R and UW_R1 with corresponding levels of significance indicated beneath.
From the matrix, there exists a fairly strong negative correlation between Cap_AT and Leverage
with a magnitude of -0.636. However, there exists no correlating between IT_R and
NetPremRec_R as seen with a magnitude of 0.000. These notwithstanding, there was no evidence
of multicollinearity among predictors. Although some independent variables were significantly
autocorrelated with each other (p-value < 0.05), there were no problems of multicollinearity since
correlation coefficients are less than the 0.9 threshold recommended by Field (2009). This,
therefore, predicts the generalizability of regression models using these variables devoid of any
60
problem of multicollinearity. This is confirmed using the variance inflation factor (VIF) with their
corresponding tolerance estimates for predictor variables in a regression model. The result is
presented in Table 4.3 with a mean VIF of 2.06 (< 2.5).

Key: 1 = CF, 2 = Cap_AT, 3 = Leverage, 4 = Size, 5 = IT_R, 6 = Sterm_R, 7 = Lterm_R, 8 = ReInsAsset_R, 9 =
NetPremRec_R, 10 = UW_R1, 11 = NPW_GPW
In summary, the significant associations between the dependent variable (CF) and predictors may
result in strong predictive abilities of these variables in determining Cash Flow in the regression
model. These variables are thus statistically acceptable in a regression analysis to determine the
drivers of Cash Flow in the insurance industry.

4.3 Regression Analysis
This section presents results from the analysis of regression models developed to examine the
determinants of Cash Flow and test hypotheses proposed in section 1.5.
In order to choose between pooled OLS and random effect, the study conducted the Breusch and
Pagan Lagrange Multiplier test for random effect. From Table 4.4, the test result suggests the
preference of pooled OLS to a random effect model. Similarly, the study performed both Jarque-
Berra and Shapiro-Wilk diagnostic tests for normal data in addition to the Pearson Correlation and
VIF tests for multicollinearity. The study also conducted the Breusch-Pagan/Cook-Weisberg test
for heteroskedasticity to ensure there is no heteroscedasticity associated with the data. Results of
these tests are presented in Table 4.4.

Both the Jarque Berra and Shapiro-Wilk test for normality estimated p-values greater than 5%
significance level which shows that residuals are independent and uncorrelated to confirm
normality and linearity as required in OLS models. Also, the Breusch-Pagan/Cook-Weisberg’s test
for heteroskedasticity confirms the presence of constant variance in the data with a p-value of
0.3156 (> 0.05). A graphical plot for of these assumptions are presented in Appendix A. A visual
examination of the histogram graphs against a normal distribution curve reveals normality in the
data. Also, the distribution of the residuals as plotted in the scatter plot in Appendix “A” reveals a
random and evenly spread one suggesting the adherence to the assumptions of homoscedasticity
and linearity (Tabachnick & Fidell, 2007). Table 4.5 presents results of the pooled OLS regression.
The application of the FAAR (DFM) model which incorporates all firm and industry factors as
well as economy-wide factors using a dimension reduction technique is, however, presented and
explained in section 4.4.

4.3.1 Determinants of Cash Flow in the Ghanaian Insurance Industry
Table 4.5 presents results for a Cash Flow predictive model using observed variables pertaining to
insurers’ core activities in capital management, financial (investment) management, risk
management, firm characteristics and underwriting activities as predictors. Results from the table
indicate that 34.59% (30.42% adj. R2) of the overall variability in Cash Flow of insurance firms is
explained by the independent observed variables. The p-value of the F-statistic as estimated from
the regression model is 0.000. This value shows the joint significance of the explanatory variables
and shows the explanatory power of the model under a strong statistical significance of 1 %. Also,
Table 4.5 summarises results of coefficients with corresponding standard errors for variables
considered to impact Cash Flow. The variable capital to asset ratio (Cap_AT) indicates an
64
estimated coefficient of 0.273277 with a strong statistical significance at the 1% significance level.
This result suggests that a 10% improvement in the capital ratio will contribute a 27.33% to Cash
Flow of firms. This result supports the theoretical prediction of the impact of capital on the Cash
Flow level of a firm as discussed in section 2.6.
Variables related to both short term and long term investment activities indicate a statistically
significant relationship with Cash Flow. Intuitively, this result suggests a more rapid movement of
cash within a firm through the positive coefficient of short-term investment ratio (Sterm_R) as
opposed to the negative coefficient of long-term investment ratio (Lterm_R) to indicate a less
frequent movement of long-term investment cash. Thus an increase in long-term investment leads
to a decrease in Cash Flow of insurers. The coefficient for risk management variable,
ReInsAsset_R, is estimated to be 0.318987. This indicates that a 10% increase in ReInsAsset_R
will lead to a corresponding 31.90% increase in Cash Flow. This estimate is also statistically
significant at 1% level of significance with an estimated standard error of 0.069277.
The relationship between variables relating to underwriting activities which are unique to the
insurance industry and Cash Flow of insurers is also summarised in Table 4.5. For these variables,
only NetPremRec_R (net premium received to assets ratio) is statistically significant in
determining Cash Flow. These results suggest that although UW_R1 and NPW_GPW influence
Cash Flow, their impact is statistically insignificant. The impact of NetPremRec_R as presented
in Table 4.5 is, however, strongly significant statistically at the 0.01 level of statistical significance.
In line with objective one and the results of this model, the determinants of Cash Flow for the
insurance industry as also found in some studies (Duchin, 2010; Bates et al., 2009; Jani et al.,
2004; Opler et al., 1999) and supported by theory are capital ratio, short term and long term
investment ratios, and industry specific variables related to reinsurance as a ratio of total assets
65
and net premium received as a ratio of total assets (Cap_AT, Sterm_R, Lterm_R, ReInsAsset_R,
NetPremRec_R).
Consistent with objective two, variables in this study are linked to various management activities
of insurers. These are capital management, firm characteristics, financial (investment)
management, risk management and underwriting activities. By this, it can be inferred from the
results from objective one that;
a. Capital management
Following Born et al. (2014), the two main variables considered as relating to capital management
in insurance are capital to asset ratio (Cap_AT) and leverage. From the regression results, Cap_AT
reveals a statistically significant relationship with Cash Flow through an estimated coefficient at
5% significance level. On the contrary, Leverage is statistically insignificant in determining Cash
Flow. These two opposing results seem to suggest a neutral effect of capital management on Cash
Flow. However, as displayed in Table 4.5, the magnitude of the contribution of Cap_AT to Cash
Flow (0.273277) as against leverage (0.114946) suggests an overall positively significant influence
of capital management on Cash Flow. This result suggests that firms can manage their Cash Flow
significantly by managing their capital to asset ratio. The statistical significance of this activity is
however reconsidered in subsequent sections using an extracted latent factor that captures capital
management of firms.
b. Firm Characteristics
Firm characteristics in this study are represented by variables size and IT_R. These variables
considered separately in the regression estimation, however, were statistically insignificant in
managing Cash Flow. The result of these variables considered individually hence fails to reject the
null hypothesis that firm characteristics do not impact Cash Flow.
66
c. Financial (Investment) Management
Embodied in this category are the variables pertaining to both short-term and long-term
investments. Although both variables statistically significantly influence Cash Flow, their
individual effects are opposing. Thus, as explained earlier, the impact of short-term investments
(Sterm_R) on Cash Flow illustrates a positive one (0.185997) while that of long-term investments
(Lterm_R) indicates a negative relationship (-0.29274). The net effect of these variables on Cash
Flow suggests an indeterminate impact of financial management on insurers’ Cash Flow. This
notwithstanding, firms can manage Cash Flow risks by concentrating on individual components to
achieve the required impact of financial management on Cash Flow. Here again, the aggregated
statistical impact of both short and long-term investments on Cash Flow is illustrated in section
4.3.4 using a latent factor extraction pertaining to financial management.
d. Risk management
Risk management practices of insurers are measured by their reinsurance with other insurance
companies. As exhibited in Table 4.5, risk management through reinsurance is statistically
significant at the 1% level of significance in determining Cash Flow. The study thus rejects at the
1% significance level the null hypothesis that risk management does not impact Cash Flow.
e. Underwriting activities
Lastly, variables uniquely pertaining to insurers’ underwriting activities were also summarised
with their corresponding level of statistical significance. These variables are NetPremRec_R,
NetPremRec_R and UW_R1. The contributory impact of NetPremRec_R on Cash Flow as shown
in Table 4.5 is statistically significant at 1% level of significance. This variable shows a negative
relationship with Cash Flow through its estimated coefficient. The disaggregated analysis of this
result also presupposes that underwriting activities impact Cash Flow through net premium
received to assets ratio as opposed to results of both underwriting gain/loss and the ratio of net
67
premium written to gross premium written (UW_R1, NPW_GPW). The aggregated impact taking
all three variables together is however re-examined using an extracted latent factor that combines
all three variables.
4.3.2 The impact of Insurers’ management practices on their Cash Flow
In order to investigate the statistical impact of key management practices of insurers on Cash Flow,
this section employed principal component analysis to capture latent variables pertaining to capital
management, firm characteristics, risk management, financial (investment) management and
underwriting activities (Born et al., 2014). Table 4.6 displays the results of the statistical
estimation of insurers’ Cash Flow using principal components pertaining to capital, risk, financial
management as well as underwriting activities and firm characteristics. The association and
contribution of observed variables to principal components are however displayed in Appendix B.
From the results, all activities in capital management, risk management, financing (investing) and
underwriting activities coupled with firm-specific characteristics were found to be statistically
significant in determining Cash Flow of insurers. The results of this estimation answer the
questions regarding the second objective (b) and provide empirical evidence to make statistical
decisions regarding the hypotheses formulated in section 1.6. The result of the estimations provides
statistical evidence to reject all the null hypotheses as stated in section 1.6. Thus, capital
management, firm characteristics, investment management, risk management, underwriting
activities do statistically significantly impact Cash Flow of firms at the 1% level of statistical
significance. Findings in this estimation also provide evidence on the explanation strength of latent
factors related to firms’ activities in capital management, financial (investment) management, risk
management and underwriting. These activities are jointly significant at 1% significant level and
contribute to 79.47% variability in insurers’ Cash Flow.

Consistent with Born et al. (2014), the next section demonstrates the application of a novel FAAR
(DFM) model that extracts latent factors pertaining to industry and economy-wide variables and
augmenting it with lagged Cash Flows to forecast future Cash Flow of individual insurance firms.
4.4 Empirical Results: Illustration of FAAR (DFM) Applications in Cash Flow Forecasting
For every individual insurance firm in this study, a time-series analysis for 32 quarter time periods
(with a four-quarter time period reserved as a holdout period) was conducted for the period 2007
to 2014. Time series results were obtained for all 21 firms with feasible data. Also, there was the
need to categorise these firms based on certain defining features. In this study, the size of a firm
was used as a basis to categorise firms into groups. The conduct and analysis of results were thus
based on: (i) entire group of 21 non-life insurance firms while sub-sample analysis was also
conducted by categorising the entire sample into (ii) large-firm (greater than 250 employees), (iii)
medium-firm (50-249 employees) and (iv) small-firm groups (below 50 employees).
69
In order to better demonstrate the procedures in the application of these models, each step in
applying DFM is illustrated using a randomly selected firm, F1. The results provide enough
evidence supporting the applicability and convenience of FAAR (DFM) models in forecasting and
subsequently managing future Cash Flows.
4.4.1 Principal Components Results:
As a first step to the application of DFM, Principal Component Analysis (PCA) was performed for
all firms to extract latent factors pertaining to insurer’s activities in capital management, financial
management, risk management and underwriting activities while taking into consideration
macroeconomic factors such as growth rate, interest rate, unemployment rate and inflation. In
order to establish the applicability of PCA, a Pearson’s correlation was performed on observed
variables to measure the correlation between explanatory variables.
The result of this matrix is presented in Table 4.7. From the matrix, there exists strong associations
between predictors and thus establishes the applicability of PCA as a variable reduction in order
to avoid a problem of multicollinearity. For example, the correlation between the size of a firm
and the net premium received ratio (NetPremRec_R) indicates a strong positive correlation
coefficient of 0.951. Similarly, there exists a strong negative correlation between short-term
investment ratio (Sterm_R) and size with a coefficient of -0.973. Evidence for the existence of
enough correlation for the application of PCA is presented as in Table 4.7 with correlation
coefficients and their corresponding significance levels indicated underneath.
Again, as applied to a typical firm F1, the results of PCA is presented in Table 4.8. Since PCA is
performed on a standardised data set, the contribution of each variable to a PC is the estimated
coefficient for that variable. The estimation resulted in the extraction of five (5) PCs with
eigenvalues greater than or equal to one ( ≥ 1)

Table 4.8: Empirical Result of PCA, Firm F1
In Table 4.8, the first principal component (PC1) is more significantly related to variables in the
categories of investment management and risk management with a fairly significant relationship
with macroeconomic variables through their contribution to PC1. For instance, the estimated
coefficient on the short-term investment ratio (Sterm_R) is 0.3421, and that for long-term
investment ratio (LTerm_R) is 0.3583. Reinsurance to asset ratio (ReInsAsset_R) contributes
0.3619 and more related to PC1 than any other PC.
Similarly, PC2 is more significantly related to variables in the category of underwriting activities
while variables size and IT_R in the category of firm characteristics loads more strongly onto PC3
than any other PC. From Table 4.8, PC4 is more related to capital management variables through

the contrasting contributions of Cap_AT (0.6484) and Leverage (-0.4684). However,
macroeconomic variables are more described by PC5 as indicated in Table 4.8. The outcome of
the principal component analysis illustrates how PCs can be linked to observed variables and this
relationship demonstrate the feasibility of a factor-augmented autoregressive model in explaining
Cash Flow variations in insurance firms.
The next step in the application of FAAR (DFM) modelling involves incorporating the results
from PCA with an autoregressive model to validate the forecasting power of the model.
4.4.2 Choice of a Baseline Model [AR(n) model]
The next step in the FAAR (DFM) model development is a choice of an appropriate baseline
autoregressive (AR) model. The time series autoregressive model estimation also necessitated the
unit root test in order to appropriately infer a suitable order for the AR model. By this, a time series
AR process up to order three was conducted for all 21 sampled firms. The result is summarised in
Table 4.9.
Table 4.9: Comparison between Baseline Models: AR1, AR2 and AR3
Source: Developed for this study from empirical results
In order to select an appropriate order for the baseline model, the Akaike Information Criterion
(AIC) was used to estimate an appropriate order for the AR models for all firms. AR1 beats AR2
All Firms Large Firms Medium Firms Small Firms
N* % N* % N* % N* %

73
and AR3 implies that the Akaike information criterion chose an AR1 order over both AR2 and
AR3 for the number of firms indicated. The results in Table 4.9, however, demonstrate the
preference for an AR model with order two (2) with 66.67% for the ‘all-firm’ category, 80%, 75%
and 50% majorities for large, medium and small firm categories respectively.
As a result of the analysis above, it is concluded that AR2 is a more appropriate baseline model
for a FAAR (DFM) model for the groups of entire sample as well as large-firm, medium-firm and
small-firm sub-samples.
4.4.3 Comparison between Baseline Model AR2 and the FAAR Model
After identifying AR2 as the appropriate baseline model, the study examined the forecasting
accuracy of the FAAR models as compared to the baseline AR2 model. In doing this, the
corresponding root mean square errors (RMSE) for all the estimated models were analysed and
compared. Without pre-specifying the optimum number of PCs to be added to the baseline model
to form the DFM model, Table 4.10 summarises the RMSE of AR2 and that of different DFM
models. Specifically, the study identified five DFM models using different numbers of significant
PCs extracted along with the AR2 baseline model. Thus: AR2+1PC, AR2+2PCs, AR2+3PCs,
AR2+4PCs and finally AR2+5PCs. Again, the number of PCs is based on significant principal
components with eigenvalues greater than or equal to one ( ≥ 1)
From Table 4.10, “5 models beat AR2” means that any one of the five FAAR (DFM) models has
RMSEs smaller than that of the baseline AR2 model. Similarly, “at least 4 models beat AR2”
implies that RMSEs of four to five models within the FAAR (DFM) models are smaller than the
RMSE estimated for the baseline AR2 model etc. For the entire sample of 21 firms, approximately
74
33.33 percent of the entire sample of firms can improve the forecasting power of the baseline
model through the application of any one of the five DFM models identified.

Differently stated, for all 7 firms (33.33%) in the entire sample, FAAR models improve Cash Flow
forecasting no matter the number of principal components utilised in the estimation. Also, about
47.62 percent of firms within the “All Firm” category can utilise at least four of the DFM models
to increase the forecasting supremacy as compared to the application of the simple AR2 model.
Finally, for most firms, specifically 18 out of the 21 firms (85.71%) can utilise either one, two, …
or five DFM models to produce an RMSE estimate which is lower regardless of the number of
principal components included. Performing the same analysis on sub-samples of different firm
sizes indicated that, for the three categories, FAAR (DFM) models which consider principal
components yield better forecasting ability of Cash Flow compared to the baseline AR2 model.
From the results, at least 80% ( 4 out of 5), 75% (6 out of 8) and 100% (8 out of 8) of large, medium
75
and small firms groups respectively can improve the forecasting power in as much as principal
components are augmented with the baseline AR2 model. It is important, however, to note that
although results from Table 4.10 illustrate the forecasting power of DFM models, they do not
specifically recommend the optimum number of PCs to be included in a FAAR model to further
enhance the performance of the model.
Remarkably, by comparing results across the different sub-sample groups, it is observed that 75%t
of firms in the small-firm sub-sample are featured with better FAAR models with
any of the five models with different numbers of principal components. Conversely, in the large-
firm sub-sample category, the number of firms featured with a better FAAR model with any
different number of PCs in the five FAAR models is an absolute 00.00 percent. This, however, can
be associated with the fact that the variation in Cash Flows of large firms is generally larger than
that of small firms or that the quality of the explanatory variables is better. It is, therefore, possible
to make use of fewer PCs to capture variations in Cash Flows of large firms as compared to small
firms which generally may need more PCs to explain possible variations in their Cash Flow.
Largely, the results as displayed in Table 4.10 suggest that an AR2 baseline model alongside
principal components enhances the forecasting accuracy of FAAR models.
The next step identifies the optimum number of PCs to be incorporated in the FAAR model to
bring the RMSE estimate to the barest minimum and thus enhance the forecasting accuracy of the
dynamic factor model.
76
4.4.4 Identifying an Optimum number of Principal Components
The previous steps illustrate how preferable FAAR (DFM) models are in predicting future Cash
Flows. This section identifies the optimum number of PCs that can be incorporated in a FAAR
model. The study conducted five FAAR models namely, FAAR 1: AR2 + 1 PC, FAAR 2: AR2 +
2 PCs, …, FAAR5: AR2 + 5 PCs for each firm. Thus, FAAR models of the form AR2 + ∑ 𝑃𝐶5𝑗=1 j,
were conducted for each firm to determine the model with the least RMSE estimate. j is the
optimum number of PCs. Table 4.11 summarises the results obtained from the DFM application
with different numbers of PCs based on a sample firm, F1. From Table 4.11, AR2 is the chosen
baseline autoregressive model of lag order two (2) while FAAR1, FAAR2, …, FAAR5 signifies
the FAAR (DFM) models with one (1) up to five (5) PCs incorporated respectively. Table 4.11
also exhibits the relative changes in both RMSE and R-squared measures as a result of including
an extra PC. Statistically, the more the number of PCs included in the model, the higher the
expected R-squared value indicating the further acute forecastability of the model. This
notwithstanding, it is not necessary to include more PCs in the model if their inclusion does not
significantly improve the model’s accuracy. In this regard, the table (Table 4.11) also reports the
adjusted R-squared in order to account for the contribution of each extra PC included in the model.
Among the five FAAR models, the models including the first and second lags of Cash Flow were
consistently significant at least at 5% significance level. PC 5 as indicated in Table 4.11 also
indicates statistical significance at 1% significant level. As seen in Table 4.11, the inclusion of
PC2 in FAAR2 has increased the forecasting error (RMSE) from 0.16136 to 0.16268. However,
the inclusion of PC3 in FAAR3 improves the adjusted R2 from 0.7218 to 0.7617 as well as reduces
the RMSE to 0.15058 representing -7.44% change in RMSE. The significant contribution of PC4
to both R-squared and a corresponding reduction in RMSE is also indicated in Table 4.11.

of their inclusion in the models. It can thus be seen that including more PCs in the model
improves both the explanation power measured by the adjusted R2 as well as the forecasting
accuracy measured by the reduction in the RMSE.
Referring to Table 4.8, the first PC is more significantly related to financial management
through its positive relations with both short-term and long-term investments. PC2 relates more
to underwriting variables while PC5 captures variables relating to macroeconomic variables
through its negative relations with interest rate and direct relations with growth, unemployment
and inflation. The time-varying movements of PC1, PC2 and PC5 are depicted in Figure 4.1 to
illustrate their time-varying patterns.

Approximately, the long run routes of both PC1 and PC2 exhibits a decrease after the year
2008 with PC2 recording the greatest fall in the first quarter of the year 2009. While PC2
illustrates a bounce back after that year with a relative increase, PC1 continued to decrease till
the third quarter of 2009 at which point it began to increase. PC1 and PC2, however, continued

to exhibit similar waves indicating decreases and increases as depicted in Figure 4.1. The
relative rise and fall in these components can be likened to their relations with macroeconomic
risks to reflect the economic instability in the Ghanaian insurance market. This study conjecture
that the small variation in PC1 and PC2 relative to PC5 may represent the underwriting cycles
of this firm due to its relations with underwriting variables. The variation in PC5 which
indicated the biggest wave as depicted in the line plot can be linked mainly to macroeconomic
variables which demonstrate a decrease from the first quarter of the year 2008 all the way to
somewhere the first quarter of 2011 and thereafter an increase till the year 2014 after which it
begins to fall again.
As a result of the significant changes observed in the RMSE and R-square with the inclusion
of different numbers of PCs, the study concludes that the FAAR model with five PCs with the
least RMSE and largest adjusted R2 can be best suited for the forecast of Cash Flow for this
firm.
Performing a similar analysis for all 21 sample firms, the results for the optimum number of
PCs to be included in the forecast of Cash Flow for each firm under the various firm categories
were inferred. The results are summarised in Table 4.12.
Table 4.12: Results of FAARM: The Optimum Number of Principal Components

Total 21 5 8 8
Note: The number in each cell represents the number and percentage of firms with that best
model. E.g., There are 4 out of 21 firms featured with FAAR1as the best model, which is 19.05%
of the entire sample.
80
In this analysis, the RMSE corresponding to each model within a firm is compared.
Accordingly, the best FAAR model for a firm is identified as the model with the minimum
RMSE among the five FAAR models. Thus for each firm in the sample, the estimated RMSEs
were compared and ordered. RMSEij, therefore, refers to the RMSE estimate for firm i under
model j. i, in this case, ranges from 1 to 21 to represent the total number of firms while j stands
for models with principal components 1 up to 5. Thus, for each firm i, the minimum RMSE
from model j can be identified for all j from 1 to 5.
Table 4.12, however, shows that the inclusion of additional PCs does not necessarily lower the
corresponding RMSEs. This can be seen for example in the category of all firms where the
inclusion of PC2, PC3 and PC4 resulted in decreased percentages of firms with those models
as the best models. In the category of all firms, the inclusion of PC2 example for reduces the
number and percentage of firms with FAAR2 as the best model from 4 (19.05%) to 1 firm
representing 4.76%. Similarly, in the category of medium firms, the inclusion of PC2 and PC3
in FAAR2 and FAAR3 respectively resulted in no firm within that category having the
corresponding model as best models. For all category of firms, FAAR5 has been identified as
the best model for forecasting Cash Flows. Specifically, within the “all firm” category, a total
of 12 firms represented by 57.14% are featured with FAAR5 (AR2 plus five PCs) as the
optimum number of PCs through significant comparison of RMSEs. Similarly, about 50% and
75% of firms within the category of medium and small firms respectively support an optimum
number of five PCs in forecasting Cash Flows. For large firm sub-samples however, FAAR3
turns to be the best model for about 40% of the sample and FAAR5 also features as the best
model for another 40% of the same sample. Thus, for this category of firms either FAAR3 or
FAAR5 can be used as forecasting models for Cash Flow.

4.4.5 Forecasting Cash Flow using FAAR (DFM) Model
The forecasting power of FAAR5 model identified in the previous section is illustrated in this
section. The study performed an in-sample Cash Flow forecast for the fourth quarter of 2014
as well as a holdout sample forecast for the first, second, third and fourth quarters of the year
2015 to validate the robustness of the model. The result of this estimation is demonstrated in
Table 4.13.
Table 4.13: Forecasting Values of FAAR Model
Source: Developed for this study
Panel A, in Table 4.13 captures observed variables with observed values. By incorporating the
results of PCA, the estimated values of each PCs together with past two period Cash Flow
values for the fourth quarter of the year 2014 are also reported in Panel B. Consequently, the
AR model alongside 5 PCs in the form AR2 + ∑ 𝑃𝐶5𝑗=1 j were utilised to forecast Cash Flow
for the fourth quarter of the year 2014. As exhibited, the forecasting error is 0.00582415 and
equivalent to GHC 1.005841. In order to check the robustness of this procedure, the study also
conducted forecasts using the holdout sample and compared the results to observed values. The
results of this step are presented in Table 4.14.

Overall, the empirical results as demonstrated with this sampled firm (F1) provides evidence
supporting the applicability and feasibility of DFM in predicting Cash Flow. Also, the model
exhibits a robust forecasting power of future Cash Flow as displayed in Table 4.14. Although
these models estimated with very minimal RMSEs, one wonders how small RMSE estimates
have to be to ensure acute forecasting ability of their corresponding models since RMSE values
are not bounded. The study, therefore, employed the Mean Absolute Percentage Error (MAPE)
which is bounded between 0% and 100%. The result of this estimate as presented in Table 4.14
further confirms the robustness of FAAR (DFM) models in forecasting future Cash Flows. The
tables demonstrating the holdout period forecast is displayed in Appendix C.
4.5 Chapter Conclusion
This chapter covered a detailed analysis of the descriptive statistics of the sample data collected
and utilised. The chapter also presented results of a Pearson’s correlation matrix of variables
to demonstrate the applicability of PCA. Regressions were estimated with key reference to the
estimation models developed from Chapter 3. The results from these statistical estimations
were analysed and findings provided empirical evidence to supplement existing literature and
provide new knowledge. The chapter demonstrated the significance of observed variables and
period-lagged Cash Flows in estimating current Cash Flow of insurers and also validated the
applicability of a novel FAAR (DFM) model in predicting future Cash Flow.
Chapter 5 presents the summary, conclusions and recommendations to the study.

CHAPTER FIVE
SUMMARY, CONCLUSIONS AND RECOMMENDATIONS
5.1 Introduction
This study models Cash Flow for insurance companies using past Cash Flow ratio data to
predict future Cash Flows. The study also determined various drivers that statistically
significantly impact Cash Flow in the insurance industry. Findings in this study will hence pre-
inform insurers on future Cash Flow needs and help them take necessary steps to manage Cash
Flow risks.
This chapter establishes how findings fit prior studies and draw conclusions and implications
for the insurance industry.
5.2 Summary of Findings
This section presents a summary of the data analysis regarding the research questions and the
various hypotheses constructed. It summarises findings of the determinants of Cash Flow in
the insurance industry as well as the relationship between principal activities in insurance and
Cash Flow.
5.2.1 Determinants of Cash Flow
As pointed by Knyazeva, Yuzvovich, Smorodina, Fomenko, and Katochikov (2016), the
activities undertaken by firms give rise to the emergence of Cash Flow but the efficiency and
effectiveness depend on how they are managed.
This study found that five (5) indicating variables are statistically significant in determining
insurers’ Cash Flow and thus its subsequent management. These are capital ratio, short term
and long term investment ratios, industry-specific variables relating to reinsurance as a ratio of
total assets and net premium received as a ratio of total assets (Cap_AT, Sterm_R, Lterm_R,
ReInsAsset_R and NetPremRec_R). These findings answer the research question concerning
84
the first objective (a) which sought to identify key determinants of Cash Flow in the insurance
industry.
Empirical results based on financial data of non-life insurers, however, found no statistical
support for variables relating to leverage, the size of firm nor firms’ use of IT and other
equipment (Size, Leverage, and IT_R) as impacting Cash Flow.
From the statistical estimations, capital to asset ratio (Cap_AT) under capital management is
statistically significant at 1% level of significance (p < 0.01) in determining insurers’ Cash
Flow. The estimated positive coefficient (0.2733) suggests that an improvement in capital to
asset ratio of insurance firms will lead to a corresponding increase in Cash Flow.
Similarly, both short term and long term investment related variables (Sterm_R and Lterm_R)
demonstrated statistical significance at 1% (p<0.01). The coefficient estimates for these two
variables indicates opposing directions relative to Cash Flow of insurers. Intuitively, the
positive coefficient estimate for Sterm_R variable suggests a more rapid movement of cash
while the negative coefficient estimate for Lterm_R variable indicates a less rapid Cash Flow.
Also, reinsurance premium to total premium written ratio (ReInsAsset_R) is significant at 1%
in determining insurers’ Cash Flow. The estimated positive sign of the coefficient for this
variable also points to a more rapid movement of Cash Flow with a corresponding increase in
ReInsAsset_R.
Finally, NetPremRec_R is statistically significant (p < 0.01) in impacting Cash Flow of
insurers. The estimated coefficient is negative with a magnitude of -0.6202 and suggests an
inverse relationship with insurers’ Cash Flow.
Also, as demonstrated in Table 4.12 the result of the autoregressive process also showed a
significant impact of past Cash Flow on the current Cash Flow of insurers. Unambiguously,
past Cash Flows relating to the first and second period-lagged Cash Flows were found to be
85
statistically significant (at least at 5% significant level) in explaining current Cash Flow. This
finding supports prior studies (Barth et al., 2001; Dechow et al., 2008; Yoder, 2006) which
assumed the random walk model, suggesting that past period Cash Flows persevere into both
current and future time periods. This result is also consistent with the findings of Born et al.
(2014), Chong (2012), Chotkunakitti (2005) and Habib (2010).
5.2.2 Summary of Findings on hypotheses formulated.
Consistent with the second objective, statistical analyses were made regarding the significance
of core management practices on Cash Flow. In this light, direct inferences were made taking
into consideration variables relating to these core practices under the pooled OLS estimation.
Also, the study employed PCA before OLS to investigate the aggregated impact of core
management practices on Cash Flow. The ensuing sections summarise the result thereof.
Hypothesis 1 (H0: Capital management does not impact Cash Flow)
In line with this hypothesis, the study made direct inferences from variables (Cap_AT and
Leverage) relating to capital management activities of firms. Although Cap_AT was significant
in determining Cash Flow, Leverage was not. Using PCA, the study found that, capital
management measured by PC2 is statistically significant (p<0.05) in determining future Cash
Flows. PC2 is an extracted principal component pertaining to capital management activity of
firms. The study, therefore, rejects the null hypothesis (H0) at the five percent (5%) level of
significance and concludes that capital management statically significantly impacts Cash Flow.
Using the same analysis, the results of the other hypotheses are as below:
Hypothesis 2 (H0: Firm characteristics do not impact Cash Flow)
The results of the statistical analyses indicate that both Size and IT_R are insignificant in
explaining Cash Flow. This outcome is inconsistent with some studies which found that the
86
size of a firm plays significant roles in determining their Cash Flow and financial performance
(Ferreira & Vilela, 2004; Ozkan & Ozkan, 2004; D’Mello et al., 2008). According to these
studies, larger firms have better credit ratings and bank credit lines which together impact their
Cash Flow. Also, the ability of these firms to raise large amounts of capital places them at an
advantage to exploit economies of scale which ultimately contribute to their Cash Flow.
In this study, the joint effect of these variables on Cash Flow measured by the fifth principal
component (PC5) using PCA found that firm characteristics are statistically significant at 99%
confidence interval in determining Cash Flow. That is, although the size of a firm and their use
of information technology (IT) and other related software processing equipment (IT_R) do not
individually impact Cash Flow, their joint effect does. We thus reject the null hypothesis and
conclude that firm characteristic statistically significantly determine Cash Flow.
Hypothesis 3 (H0: Investment management does not impact Cash Flow)
Embodied in financial (investment) management are the variables pertaining to both short-term
and long-term investments. The results of the statistical analyses indicate that both variables
statistically significantly influence Cash Flow. The aggregated impact of both short and long-
term investments on Cash Flow measured by PC4 is statistically significant at 99% confidence
level. We ones again reject the null hypothesis and conclude that financial (investment)
management statistically significantly impact Cash Flow.
Hypothesis 4 (H0: Risk management does not impact Cash Flow)
Risk management by insurance firms in Ghana is limited to their reinsurance of underwritten
losses with other insurers (reinsurers). Risk management (ReInsAsset_R) is statistically
significant at 1% level of significance (p < 0.01). Thus, risk management of firms is significant
in explaining Cash Flow. We thus reject the null hypothesis and conclude that risk management
statistically significantly impacts Cash Flow level of insurers.
87
Hypothesis 5 (H0: Underwriting activities do not impact Cash Flow)
Lastly, variables uniquely pertaining to insurers underwriting activities were also tested jointly
to find their impact on Cash Flow. The impact of underwriting activities measured by PC1 is
statistically significant at the 95 confidence level (p < 0.05). The study, therefore, rejects the
null hypothesis and conclude that underwriting activities do impact Cash Flow.
Key Findings:
a. Past Cash Flow data combined with observed variables related to insurers’ activities
improve the predictability of Cash Flow with minimal error.
b. The first two period-lagged Cash Flows consisting past t-1 and t-2 time periods
have significant abilities in determining future Cash Flow of insurers. Cash Flows
beyond past two periods were however irrelevant and contributes insignificantly
to future Cash Flow.
c. Core activities in capital, financial (investment) and risk management, as well as
activities in underwriting and firm-specific characteristics, are all significant in
determining future Cash Flows.
d. Period-lagged Cash Flows combined with latent industry variables in a FAAR
(DFM) model has a strong Cash Flow predictive ability.
e. Cash Flow financial data are relevant in forecasting future Cash Flow of insurance
firms as established in prior studies (Barth et al., 2001; Chotkunakitti, 2005;
Ebaid, 2011)
In conclusion, the regression models developed in this study are valid and adequately robust
with a reasonably high generalizability for forecasting future Cash Flows of insurance
companies for at least four future time periods.
88
5.2 Conclusions
This study investigated determinants of Cash flow in the insurance industry and validated a
model to forecast future Cash Flow of insurance firms so as to enable them to meet unexpected
future obligations and prevent insolvency. Cash Flow risks have been a major concern for many
firms and insurance firms which face unique underwriting risks not observed in other industries
are no exception. From the findings of this study, Cash Flow risks can be managed by
controlling capital ratio, short term and long term investments ratios, and industry-specific
variables such as reinsurance and net premium received ratios. Findings also revealed that
Ghanaian insurers’ in the non-life sector earn negative profits on underwriting. This result
implies that firms can generate favourable Cash Flows from other activities such as short-term
and long-term investments. The results also validated the acute forecasting ability of FAAR
(DFM) models in predicting future Cash Flows.
Findings regarding the forecasting ability of FAAR model also provide evidence that analysts
can effectively forecast future Cash Flow to assess both current and future financial health of
firms in order to protect the interest of stakeholders by preventing insolvencies and increase
insurance penetration.
5.3 Contribution to theory and knowledge
This study has successfully provided empirical evidence of the usefulness of Cash Flow
modelling to the insurance industry. This is further significant as it was conducted in the little-
researched context of Ghana, a Sub-Saharan African country so as to portray differences in
Cash Flow volatilities, industry characteristics and statutory regimes which are research issues
considered in this study.
This study has potential, therefore, to provide great contribution to the discourse on
determinants of Cash Flow, Cash Flow risks and future Cash Flow prediction as other studies
conducted in jurisdictions such as the United States and Europe
89
The conduct of this study also addresses the identified research problem by investigating
variables related to insurers’ activities that significantly impact Cash Flow and using that
information in a suitable model to predict future Cash Flow of insurance firms. The findings
provided empirical evidence that previous Cash Flow augmented with latent factors related to
insurance activities in a FAAR (DFM) model has significant ability to forecast future Cash
Flows.
5.4 Implications for Policy and Practice
Cash accounting convention to financial information reporting has been documented as one of
the important criteria for financial information disclosure to supplement the accrual-based
financial accounting. Detailed disclosure of Cash Flow data thus will enable users to better
assess the amount, timing and uncertainties of future Cash Flows. Findings in this study provide
empirical evidence to the applicability of financial data gathered from Cash Flow statements
in forecasting future Cash Flow. This will enable analysts to evaluate the ability of firms to
generate favourable Cash Flows to meet future obligations such as dividend payments and
payment for genuine insurance claims in the case of insurance firms. Also, findings regarding
determinants of Cash Flow in practice will help insurance companies make decisions that will
positively affect their future Cash Flows and also help in the formulation of policies to manage
these activities. The findings will serve as useful guidelines to both insurers and users of
reported financial information on particular variables to control in managing Cash Flow risks.
Regulators can thus rely on findings in this work to formulate policies, monitor compliance
and promote detailed and accurate disclosure of financial information relating to Cash Flow.
5.5 Recommendations
Based on the levels of significance the empirical study yielded, the research wishes to
recommend the following.
90
It is suggested that NIC enacts and effectively implements policies to monitor the pricing of
insurance products with serious penalties for defaulters so as to prevent undercutting of
premiums which is made evident in this study through the negative average underwriting gains
(UW_R1) of insurance firms. This will help prevent possible Cash Flow risks as well as future
insolvency of firms.
In order to improve the Cash Flow of insurance firms, it is also recommended that firms keep
the majority of their investments in short-term financial instruments to enable them to meet
unexpected future obligations such as insurance claims.
Also, regarding the forecastability of future Cash Flows using past Cash Flow data,
policymakers should ensure sufficient and accurate Cash Flow information is kept and
disclosed by insurers so as to aid careful prediction and analysis of firms’ financial health and
future ability to meet unexpected claims. Also, policymakers should devise methods and
strategies to encourage insurance firms to conduct internal forecasting and analysis of future
Cash Flow to enable them to manage any inherent Cash Flow risks. This will help protect
stakeholder interests and prevent insolvency of insurance firms.
It is also recommended that management of insurance companies take it upon themselves to
forecast future Cash Flows periodically so as to detect future cash flow risk and adopt strategies
to curb them before they do occur.
Future studies should, however, investigate the most effective means to manage key variables
identified to influence Cash Flow of insurance firms in Ghana through the application of
relevant financial instruments.
5.6 Limitations and Directions for Future Research
The scope of this study is restricted to non-life insurance companies within the Ghanaian
insurance industry. Results are thus specific to this industry and may not be generalizable to
91
other industries or sectors either within or outside Ghana. Consequently, future research can
imitate the methodologies employed in this study to include life insurers or firms in other
industries within or outside Ghana.
Also, insurance firms with limited and unavailable financial data were excluded from the
analysis. Specifically, only firms with feasible financial data for at least five years were
included in the analysis. Findings from this study may thus not be applicable to these firms.
The forecasting models developed assumed applicability of historical financial data in
forecasting future Cash Flows. These models were validated and are adequately robust in
forecasting future Cash Flows of non-life Ghanaian insurers for future time periods. However,
the assumptions of the applicability of past historical data stand to suggest that there remains a
fairly similar and stable economic climate in the future. Thus, drastic and substantial changes
in the business and economic environment may render findings in this research not
generalizable.
Also, since this study concentrated mainly on Cash Flow ratios, future studies can examine the
applicability of other predictive models using components such as earnings or accruals or a
combination of both to investigate the forecastability of Cash Flow in the Ghanaian context.
5.7 Chapter Conclusion
The last chapter of this study discussed the summary, conclusions and implications of findings
in this research. These findings were discussed within the context of relevant literature to
highlight the implications for both practice and policy. The chapter pointed to the research
problem identified as well as the various research questions formulated to create a link with
the findings.
This study expanded on previous studies conducted in other jurisdictions to predict future Cash
Flow of Ghanaian insurers. The study provided empirical evidence on the relevance of past
92
Cash Flows augmented with latent variables related to insurers’ activities in forecasting future
Cash Flow. The study also revealed the importance of individual predictors such as capital to
assets ratio, short term and long term investments to assets ratio, reinsurance to assets ratio and
net premium received to assets ratio as significant determinants of insurers’ Cash Flow.
Finally, this study to the best of the researcher’s knowledge serves as the pioneering research
applying the application of FAAR (DFM) model using Cash Flow data to forecast future Cash
Flow within the Ghanaian insurance industry. The study contributes to existing body of
knowledge by providing empirical evidence on the forecastability of Cash Flow of insurers in
order to meet future Cash Flow needs by properly formulating policies and managing inherent
Cash Flow risks.
