Abstract

The present study aims to outline the characteristics of the cost systems used in
banking institutions. It does so by describing the partial costs and full cost systems in
banking institutions. It then looks at the limitations of these approaches to the current
competitive conditions and goes on to consider the applicability of the activity based
costing system in the allocation of indirect transformation costs to branches, products and
customers. Finally, we will look at the findings of a questionnaire to Spanish savings banks
in order to evaluate how widespread these systems are and how they are used in savings
banks. We found that direct costs systems predominate in customer and products entries

whereas full costs systems are much more widespread in the case of branches. Furthermore,
we also found that the use of activity based costs systems is very limited.

1. Introduction
Historically, management accounting in banking institutions was introduced considerably later in
comparison with companies in other sectors. There are a number of reasons for this limited
development. This was due, on the one hand, to external causes. For example, it was not until the 80's
that competitive conditions in the banking sector fostered the development of accounting management
planning and control systems. On the other hand, there were also internal conditions that had to do with
the nature of the banking business and the operations that these companies carry out, which differ
significantly to those of other sectors. This hindered the transfer of models that had basically been
developed for industrial companies to the financial sector.
As regards internal factors, the accounting regulations set down by regulating bodies of the
banking system have traditionally been the starting point from which banking institutions have drawn
up their accounting information. The purpose of he latter was clearly to address the needs of central
Journal of Money, Investment and Banking - Issue 6 (2008) 35
banks that used this accounting information in order to supervise and control the solvency of the
financial system and to control the relevant variables of monetary policy (Túa and Larriba, 1986, p.37;
Cates, 1997, p.51-56; Kimball, 1997, p.24). Furthermore, the environment in which these companies
had traditionally operated had been sufficiently stable in order for them not to see the need to improve
their management accounting systems (AECA, 1994a, p.12-13).
On an internal level, Waden-Berghe (1990, p.569) Rouach and Naulleau (1992, p. 101-102) and
Carmona (1994, p.210) point out that the characteristic features of the products and the production
process of banks hinder the application of management accounting techniques: the intermediation
function they carry out, the permanence on the balance sheet of the main sources of income and

expenses, the problematic definition of outputs and input, given that there is no difference between the
nature of the raw material obtained via financial markets or deposit taking and the final product (loans),
the fixed cost and marginal revenue syndrome, the difficulty in allocating indirect costs to cost objects
or the diffuse figure of the customer-supplier.
However, the deep transformation of the banking system, and, more specifically, deregulation,
disintermediation and innovation processes, have ushered in changes to the competitive behaviour and
the information needs of banking institutions. We can therefore assume that the accounting systems of
these companies have most probably also evolved and established new conceptual frameworks
1
. As a
consequence of growing competition in the banking sector and the reduction of financial margins,
banking institutions have had to give increasingly greater importance to the planning and control of
their non financial costs, which has opened up the debate around the adequacy of the costs systems
currently in use in these companies (Scias, 1985, p. 48; Kimball, 1993, p. 5-20; Bos, Bruggink et al.,
1994, p.12; Carmona, 1994, p. 213). This essay aims to analyse the characteristics of the costs systems
of Spanish savings banks which operate in the universal retail banking segment. In the first place, we
will look at the different theoretical models that will enable us to analyse the financial intermediation
activity from a microeconomic viewpoint. Secondly, we will go on to describe the characteristics of
non financial costs in banking institutions, given that they influence the application of management
accounting in these companies. Thirdly, we will put forward a costs classification in savings banks that
facilitates the allocation of their non financial costs to different cost objects (centre of responsibility,
products, customers and activities). Based on the above, we can then go on to assess the use of
different costing systems, looking at both traditional costing systems (partial and full) as well as
activity based costing. The study finishes by presenting the results of a questionnaire given to the heads
of management control of Spanish savings banks with the aim of finding out which costing systems are
currently in use and how they are likely to evolve in the future.


2. The Production Process in Banking Institutions
This section aims to present an overview of the different theoretical approaches that interpret the

productive process of banking institutions. According to Bergés and Soria (1993, p. 17-23) the models
that explain the productive process of banking institutions can be grouped into three groups: partial
decision models, portfolio theory and services production. Let's look at these in more detail.

2.1. Partial Decision Models
Partial models focus either on the assets and investment decisions (loans versus the treasury) or on the
composition of the liability structure (capital versus deposits), considering the other part of the balance
sheet as an external or exogenous variable. In these models, the banking institution's balance sheet is


1
We can identify various evolution stages in bank accounting and management; for example, Chisholm and Duncan (1985, p.27-33) have divided its
historical evolution into three stages, Faletti (1986, p.88-95) refers to four stages, Rezaee (1991, p.26-28) and Roosevelt and Johnson (1986, p.30-31)
have established five stages, and Ernst & Young (1995, p.25-31) outline up to 11 phases. Having said this, the different number of stages by different
authors reflect differences in nuances but not in fundamental aspects because the evolution of information drawn up by management accounting in
banking institutions may be seen as a continuous process rooted in financial accounting that is evolving towards objectives that are more and more
related with tactical and strategic decision making.
36 Journal of Money, Investment and Banking – Issue 6 (2008)
viewed as the key element, because each of its components is modelled individually (Santomero, 2000,
p.4). When loans are regarded as outputs of the banking institution, it is assumed that, given a certain
level of exogenously determined deposits, which are not subject to optimization, the company's
management decision is focused on determining what proportion of deposited funds will be allocated
to the provision of loans and what proportion will be kept in the treasury. This is due to the fact that the
banking institution needs to maintain a certain level of liquid reserves in order to address possible
withdrawals of deposits. Obviously, maintenance of this treasury will generate an opportunity cost, so
banking institutions will have to minimise this opportunity cost by maintaining the treasury at a
minimum level. However, if the treasury that is kept is insufficient, the company exposes itself to a
high liquidity risk (Baltensperger, 1980, p.3; and Swank, 1996, p.176).
When deposits are regarded as outputs, the problem focuses on determining the optimum
balance between deposits and equity (Swank, 1996, p.177). According to this approach, a situation of

insolvency could be brought on not only by the mass withdrawal of customer deposits, but also if the
value of assets drops below that of liabilities. This scenario is less and less likely the fewer the
deposits. It can therefore be minimised by increasing the volume of equity (Baltensperger, 1980, p.10-
11; Swank, 1996, p.177). However, given that the opportunity cost of equity is greater than the
financial cost generated by deposits, in order to maximise profitability the bank need to minimise the
bank's own funds, which increases the possibility of an insolvency scenario and of meeting the ensuing
costs associated with it (Baltensperger, 1980, p.13).

2.2. Portfolio Theory Based Models
The previous models seek to address the structure of assets or liability management whilst considering
the other part of the balance sheet as exogenous. A comprehensive theory of the productive process of
banking institutions needs to simultaneously account for the structure of assets and liabilities. The
efficient portfolios selection model for banking institutions put forward by Markowitz (1959) and
developed by Pyle (1971, p.737-747) concomitantly looks at decisions concerning assets as well as
liabilities and gives us a more comprehensive view of the interrelations between assets and liabilities.
Having said this, it must be acknowledged that although portfolio theory overcomes the limitations of
partial models by determining optimum treasury, loans and deposits levels together, it still has its
drawbacks. The most relevant to this study has to do with the fact that both partial models and portfolio
selection theory regard non-financial costs as irrelevant when it comes to estimating the output level
and composition of banking institutions (Swank, 1996, p. 194).

2.3. Models Based on the Production of Services and Real Resources
The provision of financial services entails transformation costs which are not contemplated in the
abovementioned models. The services production model advocates that the production processes of
banking institutions cannot be properly analysed by simply looking at the management of its optimal
assets and liabilities structure, but that we also need to take into account the fact that both financial
intermediation and the provision of other banking services generate transformation costs, which entail
the use of real resources both human and technological (Baltensperger, 1980, p. 27-29). The models
developed by Pesek, (1970, p. 357-385); Saving (1977, p. 289-303) and Sealey and Lindley (1977,
p.1251-1266) are approaches based on production and cost functions, and enable us to study the

banking institution's behaviour from the point of view of profit maximisation. According to the above
models, the activity of banking institutions consists of providing a range of different financial services
(both intermediation and other kinds of services), the production of which can be expressed in
accordance with a production function. The inputs of this production function are a combination of
different types of factors consisting of real resources whereas the outputs are different possible
combinations of assets, liabilities and services. Hence the production function, along with the
balancing of the accounts between assets, liquidity and liabilities, interest rates that are externally set
by the market and legally established coefficients, make up the restrictions under which banking
Journal of Money, Investment and Banking - Issue 6 (2008) 37
institutions must operate and try to maximise their profits. These profits will ultimately depend on the
difference between revenue generated from the sale of their services on the one hand and the total costs
of their inputs both financial and non financial on the other (Sealey and Lindley, 1977, p. 1255;
Santomero, 2000, p.3).
The following sections will discuss the problematic of the costing structure of real resources in
banking institutions and look at how these are classified for management accounting purposes. This
will be followed by an overview of the different costing systems identified in the literature, partial
costs, full costs and activity based costing. And finally, we will present the findings of an empirical
research study concerning the costing systems used by Spanish savings banks.


3. The Cost Structure of Banking Institutions
Before we proceed to assess the different existing cost systems and their application to banking, we
would like to highlight some of the characteristic features of the banking business which influence the
cost structure of its costing systems. These characteristic features can be summed up as follows
(Sloane, 1991, p.76-79; Sapp, Rebischke et al., 1991, p.56-57):
• Variable work load: the volume of operations fluctuates enormously from one moment to the
next, which obviates the problem of capacity management, given that at certain times there are
"peaks" whilst at other times there are "valleys" which means that these resources are underused.
• High fixed costs: resources are usually allocated to covering "peaks" of activity. However, the
cost of these resources does not vary with the volume of transactions, because they have a large

fixed component.
• Predictability of the activity: although the demand for services tends to be highly variable, it is
relatively easy to predict, because it follows a cyclic behaviour pattern, which offers the
possibility of turning part of fixed costs into variable ones by means of outsourcing.
• Mass services production activities: a comparison can be drawn between the high volume of
repetitive operations in banking institutions and traditional industrial mass commodity
manufacturing, which facilitates the use of methodologies that originated in industry and the
setting up of a standard costing system.
• Joint production and an undefined product: the banking product is physically indefinable which
makes it more complex to identify. For example, when a banking institution issues a loan to a
customer, the latter must open up a current account to meet the loan payments. If on top of this
the customer orders a cheque book on his current account and takes out a life insurance policy,
we have four interrelated products.
• Low cost traceability: given that we are dealing with joint production activities with elevated
fixed and indirect costs there are many resources that are shared by activities, customers, products
and centres of responsibility.
As far as we see it, the most significant factors that influence the applicability of different cost
systems in banking institutions are on the one hand, the significant weight of indirect costs in relation
to cost objects, which makes it difficult to trace them in relation to cost objects. Similarly, given that a
large part of the operations carried out by banking institutions are of a repetitive nature and susceptible
to standardisation, this makes it feasible to consider calculating the costs of these operations and
allocating them to cost objects, and to introduce the use of standard costs as a planning and control
instrument.


4. Costs Classification in Banking Institutions
The classification of the non financial costs of banking institutions may prove useful in studying the
applicability of different cost systems to banking institutions. Although we can make different
classifications of these costs, the most relevant for our purposes is the difference between
38 Journal of Money, Investment and Banking – Issue 6 (2008)

transformation and overhead costs (AECA, 1994a, p.61-62): "transformation costs are costs that are
generated in profit centres and in operational cost or general services centres. In general, the costs of
these centres are directly or indirectly related to the consumption of products and services on the part
of customers". At the same time, transformation costs can be divided into direct and indirect costs,
depending on their relation to cost objects (AECA, 1994a, p.61):
• Direct costs, are those costs that can be unequivocally and directly allocated to cost objects, in
other words their allocation is controlled economically in an individualised fashion.
• Indirect costs, are costs that cannot be directly allocated to cost objects because there is no exact
allocation of funds that enables us to estimate the consumption of these costs by cost bearers,
It should be noted that a significant number of transformation costs of banking institutions are
dual in nature when viewed from the previous classification criterion, to the extent that certain
transformation costs can be direct with respect to the branches network but indirect in relation to
products and customers (De la Cuesta, 1996, p.85-87). In banking institutions, transformation costs
basically correspond to personnel costs, depreciations and other general costs, which although they are
difficult to allocate to customers and products, are generally easier to allocate to responsibility centres
(Cole, 1995, p.152).
The second costs category corresponds to overhead costs, which are generated in the bank's
organisational centres. These costs are generated by the various functions related to management,
administration, organisation and control. In general, these are indirect in relation to all the cost objects.
These costs are treated as costs assigned to support all the company's functions, and as such they are
independent of production volume, the existing product lines and of the markets they serve (AECA,
1994b, p.58).


5. Traditional Cost Systems in Savings Banks
The process of allocating non financial costs to different cost objects begins with deciding on which
costs must be transferred to cost objects. This enables us to identify two types of approaches, the
partial costs system, which allocates only a part of the company's costs and the full cost systems, which
allocates all the costs (Amat and Soldevila, 1997, p.46). In any of these alternative systems, "the cost
allocation process is usually a sequential process that consists of two stages. In the first stage, the

different cost categories are added to the different intermediate cost objects (cost centres or sections)
and in the second stage, costs are allocated to the final cost objects" (AECA, 1994b, p.72).
Thus, coming back to the classification of transformation costs of banking institutions which
differentiated between direct and indirect costs, it is worth considering the use of partial or full cost
systems in banking institutions (AECA, 1994a, p.87-89).

5.1. Partial Cost Systems
This system only takes into account the direct transformation costs of a cost object and does not assign
indirect transformation and overhead costs, which are simply allocated to cost centres or sections
(AECA, 1994b, p.87). According to Anthony and Dearden (1976, p.554), the application of the partial
costs system in banking is basically a consequence of the existence of the considerable volume of
common and joint costs in relation to the different objects, which complicates their allocation to cost
objects. But at the same time, given that the direct costs are usually quite insignificant, that variable
costs may be practically non-existent and that their outputs are difficult to measure, assessing efficacy
and efficiency by means of a partial costs system seems an excessively limited approach.
This cost structure also helps to explain why banking institutions were slower to adopt full cost
accounting systems than were companies of other sectors (Sloane, 1985, p.75; Kimball,1993, p.7).
Authors such as Mecimore and Cornick (1982, p.13-18), when faced with the peculiarities of
the cost structure of banking institutions, consider that the profitability analysis of the different costs
objects should be based more on contribution margins than on net margins. Their argument is that it is
Journal of Money, Investment and Banking - Issue 6 (2008) 39
preferable for decisions to be based more on the philosophy of contribution than on that of absorbing
costs. Similarly, Gardner and Lammers (1988, p.36), after carrying out a survey of United States
banks, found that banks gave very little importance to obtaining full costs and attributed greater
importance to cost management and direct costs.
However, as the mass of indirect costs gradually increases, the direct costs system or
contribution system becomes less and less important for planning and control purposes, although it is
still applicable to certain special types of decision making (De la Cuesta, 1996, p.88). It is therefore of
limited use in the case of multi-product companies with a high level of indirect costs. Consequently,
considering the cost structure of banking institutions (the predominance of fixed indirect costs), the

margin obtained for cost objects by this method may end up being of little significance.

5.2. Full Cost Systems
In addition to direct costs, the full cost system also allocates all or part of their indirect transformation
costs to cost objects (Leguay 1984, p.19). Rezzae (1991, p.29) points out that the traditional full cost
methods applied to banking have been based on establishing cost centres, generally related to the
organisational structure, which then transfer their costs to the different organizational units, products,
customers or distribution channels. Marigot's work (1988, p.178-181) also follows along these lines.
He in fact proposes a sequential allocation of non financial costs to the different responsibility centres,
as can be seen in Figure 1.

Figure 1: Full costs system (I).

40 Journal of Money, Investment and Banking – Issue 6 (2008)
Rouach and Naulleau (1994, p.124-132) and Rouach (1998, p.21-23) also follow the same
lines. They put forward a full cost model by sections that involves the allocation of indirect
transformation costs to cost objects in five stages, which are summed up in Figure 2:

• Determining which costs will be incorporated in the accounting analysis.
• Proceeding to locate costs in responsibility centres.
• Proceeding to allocate the costs of general services centres into operational and profit
centres.
• Calculating the cost of service provision operations in the operational service centres, which
can then be allocated to the cost objects that consume them
2
,
• calculating the repercussions that the costs of operations have on cost objects. The costs that
are allocated to each cost object are equal to the number of operations carried out multiplied
by the unit cost of each type of operation.


6. The Limitations of Traditional Cost Systems in Savings Banks
Given the above, we can conclude that the application of any of the traditional costing systems leads to
a paradoxical situation. On the one hand, if we opt in favour of a partial cost system and only attribute
direct costs to their final cost objects, then a situation arises whereby only a small fraction of costs can
be allocated to cost objects whereas the rest, which are indirect, are not accounted for under centres of
responsibility, products or customers.
On the other hand, if we opt for a full costs model, we will be faced with a number of
limitations. Ernst and Young (1995, p.123), Sapp et al. (1990, p.54), Raihall and Hrechak (1994, p.44),
Kimball (1997, p.31) and Helmi and Hindi (1996, p.8) argue that the traditional costing systems
applied in banking assume that indirect costs are generated by production volume whilst ignoring the
effects that the diversity and complexity of operations have on indirect costs. On the other hand, as

banking institutions develop initiatives in order to meet new competitive requirements, the weight of
indirect costs on their structure increases because the costs of market research, marketing, the
introduction of new products, automatisation of transactions, new technologies, etc are clearly on the
rise. Furthermore, Raihall and Hrechak (1994, p.45) point out that “the number of cost drivers that


2
The unit per operation is perfectly applicable and easily identifiable when it comes to calculating the unit cost of the provision of services in these types
of centres. For example, the number of cheques handled, the number of discounted charges, number of transfers, stock purchase and sale orders,
coupons, etc. By simply adding up these operations the bank can get a precise idea of the magnitude of their evolution.
Journal of Money, Investment and Banking - Issue 6 (2008) 41
have been used to attribute indirect costs to cost objects is very small, which makes it difficult to
discern the differences between the company's diverse service production processes as regards their use
of resources”. Hence it is practically impossible to trace costs and this makes it difficult to develop
initiatives to improve their management (Mérindol and Obadia, 1998, p.28).
Hence, a full costs system that allocates indirect costs under a few headings based on business
volume may be acceptable in industries that have a relatively small proportion of indirect costs and
where output is reasonably homogeneous. This is not advisable however in multi-product industries
with heterogeneous outputs which are difficult to measure and with a high percentage of indirect costs
(Carmona, 1994, p.213; Raihall and Hrechak, 1994, p.44-45; Kimball, 1997, p.31, Druker, 1995, p.8;
Lacan, 1986, p.152; Merlo, 1995, p.40; De la Cuesta, 1996, p.88).


7. The ABC System in Banking Companies
During the nineties traditional costing systems came under minute scrutiny: loss of relevance, lack of
reliability, inability to provide valid information for decision making as well as obsolete methods or
systems that were unadapted to the realities of companies are some of the criticisms that were directed
at traditional cost accounting systems. Johnson and Kaplan (1987) and Mevellec (1988, 1991), after
demonstrating that traditional methods were unable to address the needs of companies, went on to
argue in favour of their comprehensive overhaul and proceeded to reinvent management accounting.

Deregulation, that has been the general standard in financial sector companies, has facilitated
the entry of new competitors and has given companies a greater degree of freedom with regard to
pricing and the product mix they offer. Companies in this sector have witnessed the disappearance of
the protectionist environment of regulated prices and the advent of new competitors and at the same
time are faced with significant threats and opportunities, the management of which demands a
comprehensive knowledge of markets, customers, products and the search for new competitive
advantages. As a consequence, in the late eighties, a series of new concepts were introduced into cost
accounting. One of the chief innovations in this respect was the activity based accounting system. The
academic world has shown a considerable amount of interest in the application of the activity based
costing system in banking institutions. In recent years a number of authors have published studies that
assess the applicability of ABC and ABM methodologies to banking institutions, some of the most
important of which are the studies by Kerebel (1997, p.60-62), Helmi and Hindi (1996, p.5-19), Blake
(1996, p.5-43), Ernst and Young (1995, p.123-140), Weiner (1995, p.37-38), Kimball (1993., p.5-20),
Mabberly (1992, p.17-79), Sapp, Crawford and Rebischke (1990, p.53-62; 1991, p.75-86), Mérindol
and Obadia (1998, p. 27) or (Bos, Bruggink et al., 1994, p.12-16).
The development of a series of different theoretical approaches has gone hand in hand with the
increasingly widespread use of the ABC system among banking institutions. Kimball (1997, p.31),
Weiner (1995, p.19) Innes and Mitchell (1997, p.190-205), (Berry and Britney, 1996, p.36), Hartfeil
(1996, p.23), Carroll and Tadikonda (1997, p.1) and Sweeney (1994, p.19; 1997, p.26) point to the fact
that from the beginning of the nineties North American and British banking companies began adopting
activity based costing in an attempt to attain a better understanding of the factors that influence the
behaviour of their costs and to improve the allocation of costs to cost objects.
According to Obadia and Faubert (2000, 33), "ABC analysis enables us to draw up a model of
the logical sequence of cost formation and to reconcile the degree of profitability of different products,
customers and distribution channels. The ABC system enables us to draw up a model of the following
chain of sequences:
• customers consume products and services via a distribution channel (branches, internet,
telephone ),
• the product-service/ distribution channel combination involves the performance of a series
of activities,

• these activities use up the company's resources".
42 Journal of Money, Investment and Banking – Issue 6 (2008)
For Mérindol and Obadia (1998, p.26) the ABC method works under a different logic and to a
large extent does away with long lists of allocation components (Figure 3). Kimball (1997, p.32) and
Hankes (1995, p. 9) suggest that the ABC system enables banks to reduce the number of costs that are
regarded as indirect costs in relation to cost objects. In this way, a larger proportion of costs that were
initially regarded as indirect costs can be directly allocated to products, customers or centres of
responsibility that are directly responsible for their existence due to activities' consumption of
resources.

With regard to the applicability of the ABC system to banking institutions, Kaplan and Cooper,
(1991, p.467) and Kaplan and Cooper (1999, p.229) highlight the fact that there are no substantial

differences between the implementation of activity based costing in cost centres belonging to a
manufacturing company and costs centres of a service company. And indeed, there don't appear to be
any substantial differences between the specific proposals in the literature for applying the ABC
system in banking companies ABC (Sapp, Rebischke et al., 1990, p.53-62, Sapp, Rebischke et al.,
1991, p.75-86; Mabberly, (1992), Ruff and Hill, 1992, p.28-37; Weiner, 1995, 19-44; Ernst and Young,

We believe that, although the description of the ABC model applied to banking institutions does not differ from that developed for industrial
companies, the nature and type of activities carried out by the former and the latter vary significantly. Similarly, the hierarchy of activities in these two
types of companies can be established based on different criteria.

8. Survey Universe and Methodology
Our survey universe is made up of 47 savings banks that are registered in the Official Bank's Registry
of the Bank of Spain in 2006. We sent out 47 questionnaires, and received 26 replies, which represents
a response rate of 55.31%. The 26 savings banks that responded to the survey represented 73.6% of the
total assets of all savings banks in Spain. This response rate is comparable to those of similar research
initiatives, both nationwide and internationally. For example, the BAI (Bank Administration Institute)
carried out a survey with the aim of finding out which accounting and management control systems
were being used by North American banks. The BAI questionnaire was sent out to the 250 biggest
banks in the United States, and 40 banks responded (16%) although the respondents accounted for 43%
of the sector's total assets. Similarly, Gadner and Lammers (1988) carried out a survey on the
application of management accounting between banks and saving and loans associations. They selected
the 50 largest banks and the 20 largest saving and loans associations according to their asset volume
and sent out 70 questionnaires through the post. They received responses from 49 institutions, with a
response rate of 68%. Innes and Mitchel (1997) carried out a survey with postal questionnaires in order

to find out to what extent the ABC costs system was being used by financial institutions in Great
Britain. They sent out their questionnaire to the 60 largest financial companies in Great Britain and the
response rate was 51.6% (31 companies). The response rate to our questionnaire is comparable to those
obtained in other research studies on banking management accounting carried out using the same
methodology. The responses were segmented according to company size, measured based on their total
assets. They were divided into three categories: the larger savings banks with assets above six billion
euros (segment A); medium sized savings banks with assets above three billion euros (segment B); and
smaller savings banks with assets below three billion euros (segment C).
The research method we used consisted of a questionnaire sent out by post to the heads of
management control of all Spanish savings banks. Two variant analysis was used to tabulate this
questionnaire. This is the method of choice for studying relationships between variables taken two by
two (Pedret, 1997, p. 31). This type of analysis is useful for finding answers to questions such as for
example, whether the size of the savings bank influences the costs system that is used or whether there
is any relation between the size of the institution and the funds transfer system it uses. The data was
treated using the programme SPSS version 6.12. In our case we used two variant analysis between two
qualitative variables and contingency tables were used to present the results.


9. Costs Systems in Spanish Savings Banks
In this section we will go on to study the use that savings banks make of cost accounting. In order to do
this we have thought it useful to identify the costing systems they use in order to allocate
transformation costs to centres, products and customers. In addition, in the light of the current
conditions of competition, the diverse range of products and services savings banks offer and the
structure of their transformation costs, these companies appear to be ideal candidates for the
introduction of the activity based costing system. We studied how much knowledge savings banks
have of the ABC system and how widespread its use is in these institutions.
The majority of costing systems used by savings banks are based on the organizational chart
(Table 1). In 76.9% of savings banks, the centres that make up their organisational structure overlap
with the cost centres they use for accounting purposes.

In Table 2 we can see that the costs centres set up in savings banks are not only related to the
organisational structure but that in the majority of cases (61.5%) the banks make a differentiation
between operational and support cost centres. However, there are considerable differences between the
different savings bank segments. Whereas 75% of banks in segment A distinguish between operational
and support centres, this percentage drops to 60% for segment C and 50% for segment B.

Tables 3, 4 and 5 show which transformation costs are transferred to the final cost objects
(offices, products and customers). A differentiation was drawn between different cost objects, given
that, as we have already discussed, a significant part of the transformation costs of savings banks are
direct costs from the point of view of offices but indirect from the point of view of products and
customers. Thus, by identifying which costs affect the cost objects, we can determine whether savings
banks opt in favour of partial or full cost systems.
Table 3 outlines the characteristics of the costing system used to allocate transformation costs to
the branches network. As we can see, the use of the direct costs system is not at all widespread. Only
two banks replied that they only allocate direct costs and do not allocate any kinds of indirect costs to
the branches. In fact, 92.3% allocate their direct costs to the branches as well as a part of their indirect

Journal of Money, Investment and Banking - Issue 6 (2008) 45
costs. In order to find out what criteria they used to allocate indirect costs we asked the savings banks
to identify the procedures they use, offering them different options which were not intended to be
mutually exclusive, because a bank could use simultaneously both approaches:

• the allocation of indirect costs in proportion to the business volume generated by each
branch: the criterion is applied by 13 banks (50% of the study sample). The majority of
banks that use this procedure belong to the smaller savings banks segment. We can
therefore conclude that the allocation of indirect costs based on business volume criteria
decreases as the size of the savings bank increases.
• the allocation of indirect costs according to the real consumption the branches make of
them:
• 14 savings banks said that they follow this criterion (53.8% of the sample). With this
approach the bank calculates the unit cost of the services the operational and/or discretional
centres perform for the branches and these are then debited to the profit and loss account of
the branches, multiplying the volume of services by their unit cost.
It should be pointed out that use of one of the abovementioned criteria for certain types of
indirect costs does not impede out the use of other procedures for other types of indirect costs, because
if we add up the number of banks that allocate them according to volume (50%) and those that do so
according to the actual consumption of indirect costs (53,8%), this gives us more than 100%.
We can therefore conclude that Spanish savings banks are clearly in favour of allocating
indirect costs as part of the planning and control of the profit and loss accounts of their branches. In
doing so they make use of procedures which combine the allocation of indirect costs based on the
business volume that each branch generates and allocation based on the actual consumption of indirect
costs by the branches. Having said this, it should be pointed out that the bigger the savings bank the
less frequent the allocation of indirect costs based on business volume.
Another cost object that management accounting focuses its attention on are products. Product
portfolio management involves estimating the profit and loss of different products and services with a
certain degree of reliability. In order to do so, the savings banks have two alternative options; in the
first place they can deduct only the direct costs of products from the financial margin generated by
46 Journal of Money, Investment and Banking – Issue 6 (2008)
these products. The second alternative, apart from taking into account direct costs also enables them to
allocate to products a part of the indirect transformation costs that contribute to their maintenance. As

we have mentioned previously, the transformation costs of savings banks are easily traceable to the
branches, which explains why the full costs system is so widespread at this level. In contrast, the
possibility of establishing a correlation between these costs and products is much more limited. Hence,
the direct costing system is more likely to predominate at the level of products. Table 4 shows us that
the majority of savings banks simply assign to products their direct transformation costs (73.1%) and
do not on the other hand allocate any indirect costs that may correspond to them.

This leads us to the conclusion that the direct costs system is the most widespread costing
system used by savings banks to assign their transformation costs to their product portfolio. This
practice is especially more significant in the case of the smaller savings banks.
If we look at our findings for the allocation of transformation costs to customers in Table 5 this
leads us to similar conclusions. 73.1% of the savings banks in the sample simply allocate to customers
the direct costs that are clearly assigned to them. We once again observe that this practice is much
more widespread among the smaller savings banks than it is among the large ones. The banks that
choose to allocate part of their indirect costs to customers (26.9%), generally tend to do so based on the
real consumption of services represented by indirect costs (85.7%) whereas a minority (14.2%) allocate
them proportionally to the business volume of each customer or market segment. Hence, as far as the
customer category in cost objects is concerned, savings banks also prefer to use the direct costs system
to allocate their transformation costs to customers.

Table 6 shows the level of importance that savings banks give to having relevant analytical
information on the different cost objects. In order to measure this, we asked the savings banks to order
by order of importance from (1) to (6) (one being the most important and six the least) the usefulness
of different types of information listed in Table 6. In the event that the savings bank did not have
analytical information on a particular factor we asked them to evaluate its potential usefulness.
From Table 6 we can conclude that all the savings banks coincide in pointing out that the most
relevant cost object are customers and customer segments. The second most important item are the
branches. Consequently, whereas the use of full cost systems seems to focus almost exclusively on the
branches and centres of responsibility, from the point of view of usefulness and importance to
management, savings banks attach greater importance to information on profit and loss by
customers/segments.

As we have already seen, given the cost structure of banking institutions, the use of an activity
based costing system may be an alternative for improving the process of allocation of indirect costs to
cost objects and the following tables study the prevalence of the ABC system in savings banks. We
found that savings banks are widely familiar with the activity based costing system. 96.2% of the heads
of management control of savings banks replied that they were familiar with the activity based costing
system. However, comprehensive knowledge of the ABC system does not go hand in hand with its
48 Journal of Money, Investment and Banking – Issue 6 (2008)
widespread use on the part of savings banks. Table 7 shows that 69.2% of savings banks in the sample
do not use the ABC system. We can also see that the use of this costing system is related to size and
that only one bank from the small savings banks segment says that it uses the ABC system.

In Table 8 we can see that of the 8 savings banks which state that they are using the activity
based costing system, only 1 of them does so in a generalised fashion throughout the organisation
whereas 5 banks use it only in certain business processes and 2 banks use it in conjunction with other
cost systems.

Table 9 measures the importance that the savings banks which use the ABC system (8 banks)
place on the different applications of the ABC system. In order to do this they were asked to evaluate
the relevance of a series of proposed objectives on a 1 to 5 scale (1= none at all, 5= very high) The
most relevant objective was the reduction and control of transformation costs (4 points, which means
that this objective was assessed as having a "high" degree of relevance. From Table 9 we can conclude
that the interest that savings banks show in the ABC system is basically limited to its use as a
transformation costs reduction and control system and that the remaining objectives trailed far behind.

Finally, having already mentioned the fact that the use of ABC systems is quite limited (only
30.8% of savings banks declared that they use it in their companies), we decided to find out if they
were likely to increase its use in the future. In order to do this we decided to ask the heads of
management control who had stated that they didn't employ this system (18 savings banks) whether
they considered its introduction appropriate. In Table 10 we can see that 38.8% of banks which
currently don't use the ABC system do not consider its introduction necessary or appropriate. It should
be pointed out that of this percentage, the majority, (71.4%) were smaller savings banks. 50% of the
savings banks that do not use the ABC system consider that its introduction is a good idea.

Given the above, we can therefore conclude that, although the ABC system is not prevalent
among savings banks, its use is likely to increase in future, especially among large savings banks.

Given the findings of our study we consider that the future introduction of the ABC system in savings
banks is compatible with the use of other costing systems and that its use will generally be limited to
specific key business processes and activities or to processes which represent a large percentage of
their transformation costs.


10. Conclusions
This study has looked at the peculiarities of the non financial costs structure of savings banks. Our
findings show that a significant part of these transformation or overhead costs are indirect in relation to
customers and products and to a lesser extent in relation to the branches and centres of responsibility.
Given this state of affairs, we expected that the use of partial cost systems would be widespread in the
case of customers and products and that the full costs system would be more common in the latter case.
Our findings did in fact show that as regards branch management control, savings banks tend to use
full costs systems whereas direct costs systems predominate in the case of products and customers. As
a way of getting around these limitations we suggested that the activity based costing system is
especially suited to multi-product industries with a high degree of indirect costs, a category which
universal retail banking and consequently savings banks fall into. However, our findings show that
activity based costing is not at all widespread, and that those savings banks that do use it generally do
so only for specific business processes. However, we found that the ABC system is basically used with
the aim of reducing and controlling transformation costs. Hence the development of ABC systems
could lead to significant improvements in this area. It could lead to a more objective allocation of the
majority of indirect transformation costs and thus provide more relevant information for decision
making, considering that certain types of decisions need to be based on the total costs allocated to
Journal of Money, Investment and Banking - Issue 6 (2008) 51
products and customers, not just on their direct costs. Otherwise, they run the risk of basing decisions
on maximising business volume instead of on profitability criteria.
