A finance manager of a firm looks for these things on the assets side of the balance sheet. For capital, he turns his attention to the other side of the balance sheet and never commits the mistake of adding the two together while taking the census of total capital of the business. His purpose is to balance the two sides in such a way that the net worth of the firm increases without increasing the riskiness of the business. This balancing may be called financing, i.e. financing the asset of the firm by generating streams of liabilities continuously to match with the dynamism of the former. Although assets denote wealth of the firm, firms may not like to hold many of the assets appearing on the balance sheet. While they may like to hold fixed assets like plant and machinery which generate goods and services; the sales of which generate a profit; current assets like debtors, inventories or even cash are not likely to be held in the business. The ideal situation for the firms is where the production process takes very little time to convert the input to finished goods which gets sold immediately in cash the moment it rills out of the process; and the input market is so perfect that any amount of raw material is available at any time at a fixed price. However, this is a visionary situation difficult to have. Instead, the production process takes quite some time; the finished products are not sold so quickly which means a quantity of stocks remains in the godowns. Moreover, the sales are not always in cash; some amount of credit has to be given and the input markets are so uncertain that the firms to keep a certain amount of safety stock all the time. These ‘non-ideal’ conditions thus generate certain assets which are called current assets. These current assets block the funds which should have been otherwise available for meeting working expenses. Each and every current asset of a firm is, therefore, nothing but congealed fund for working expenses. And because business is a continuous process, every cycle of operation generates these current assets which need to be funded for immediate financing of working expenses. This funding for working expenses is done by, what we popularly call, working capital. 1.2 Definition and Concept of Working Capital The term working capital originated with the old Yankee peddler, who would load up his wagon with goods and then go off on his route to peddle his wares (Brigham and Gapenski 1996). The 5 merchandise was called working capital because it was what he actually sold, or turned over, to produce the profits. The wagon and horse were the fixed assets. The peddler generally owned the horse and wagon so, they financed with equity capital. But, he borrowed the funds to buy the merchandise. These borrowing were called working capital loan, they had to be repaid after each trip to demonstrate to the bank that the credit was sound. If the peddler was able to repay the loan, then the bank would make another loan, and banks that followed this procedure were said to be employing sound banking practices. The concept of working capital was, perhaps, first evolved by Karl Marx (1867), thought in a somewhat different form. Marx used the term ‘variable capital’ meaning outlays for payrolls advanced to workers before the goods they worked on were complete. He contrasted this with ‘constant capital’, which according to him, is nothing but ‘dead labor’, i.e. outlays for raw materials and other instruments of production produced by labor in earlier stages which are now needed live labor to work with in the present stage. This ‘variable capital’ was the wage fund which remains blocked in terms of financial management, in work-in-process along with other operating expenses until it is released through sale of finished goods. Although Marx did not mention that workers also gave credit to the firm by accepting periodical payment of wages which funded a portion of workin-process, the concept of working capital, as we understand today, was embedded in his ‘variable capital’. The working capital of a business enterprise can be said as portion of its total financial resources which is put to a variable operative purpose. The facilities that are necessary to carry on the productive activity and represented by fixed asset investment (i.e. non-current asset investment) are to be operated by working capital. Van Horne and Vachowicz (2004) defined the working capital management as that aspect of financial activity that is concerned with the "safeguarding and controlling of the firm's current assets and the planning for sufficient funds to pay current bills." In an annual survey of industries, the working capital is defined as "stocks of raw materials, stores, fuels, semi finished goods, including work in progress and finished products; cash in hand and at the bank and the algebraic sum of sundry creditors as represented by (a) outstanding factor payments e.g. rent, wages, interest and dividends; (b) purchase of goods and services; (c) short term loan and advances and sundry debtors comprising amounts due to the factory on the account of sale of goods and services and advances towards tax payments." But with the evolution of the concept came the controversy about the definition of working capital. Guthman and Dougall (1948) defined working capital as excess of current asses over current 6 liabilities. This view was elaborated by Park and Gladson (1951) when they defined working capital as the excess of current assets of a business (cash, accounts receivables, inventories, for example) over current items owed to employees and others (such as salaries and wages payables, accounts payables, taxes owed to government). This concept of working capital, as has been commonly understood by the accountants, more particularly understood as net working capital to distinguish it from gross working capital which is discussed later. Walker (1974) holds that this concept is useful to groups interested in determining the amount and nature of assets that may be used to pay current liabilities. These interested groups, as suggested by Walker, mostly composed of creditors, particularly the supply creditors who may be concerned to know the ‘margin of safety’ available to them should the realization of current assets be delayed for some reasons. 1.3 Working Capital Management Although economists regard fixes capital as what is represented by long-term assets, a finance manager defines fixed capital as that having long term maturity. It is not essential to restrict utilization of the fixed capital to finance fixed asset only; rather, to use the fixed capital to finance a part of current assets also in addition to financing fixed assets is preferred. There may also be a situation where all the fixed and current assets are financed from fixed capital only. In the latter case, the firm will have current assets but no current liability, but we cannot say that the firm does not have any need for working capital. The firm might not desire to contract current liability, but its operations would have generated current assets which have to be funded to ensure continuity of production. This fund is, in fact, an additional fund over and above the fund required to meet working expenses of the firm. Management of current assets is, therefore, distinct from the management of fixed assets. But more important than this tautology is that because of the dynamism of the current assets, the finance manager has to be constantly on guard to ensure that their dynamic stability is not impaired to affect the net worth of the firm negatively. Gross current assets should, therefore, be understood by their own meaning, connotation and effect on the firms and should not mechanically equated with gross working capital just because arithmetically the two may appear to be same in a balance sheet. Besides, the funding operations of the current assets are quite distinct from the management of current assets. A modern day finance manager first projects the level of current assets of the firm under projected sales and then tries to find out sources to finance these current assets in such a way that cost of capital is optimized. Management of gross current assets and gross working capital, or simply working capital, is not one and the same. The total of projected current assets is an aggregate 7 figure for which capital has to be raised and the two may not have any bearing on each other. The profiles of the types of capital so raised in regard to the risk opportunity for gain or loss and also the cost are different from that of current assets. Working capital is so much in use in common parlance and is so much misunderstood. Even among the professional managers the controversy and confusion persist. While an accountant will regard working capital as current assets minus current liabilities and call it as net working capital, a finance manager will consider gross current assets as the working capital. Both may be true, but their concerns differ. The former’s concern is arithmetical accuracy trained as he is to tally the two sides of the balance sheet. But the finance manager’s concern is to find fund for each item of current assets at such costs and risks that the evolving financial structure remains balanced between the two. When one asks a production controller: what is working capital? His answer is very simple and straightforward that working capital is the fund needed to meet the day-to-day working expenses, i.e. to pay for materials, wages and other operating expenses. Is there any difference between the statements of ultimate analysis; the latter may be true, but according to the accountant or the finance manager it is the very working expenses that get blocked in current assets along the productivedistributive line of an enterprise, and net working capitals that liquidity which takes care of the working expenses if the line gets extended due to any reason. However, the notion of the liquidity itself has undergone considerable changes with the advances in financial management during the recent years. Liquidity has so far been defined as a pyramid of current assets in descending order of realisability with cash holding the top position and inventory, the last. This notion has given rise to liquidity ratios such as current ratio or quick ratio, and later to the concept of net working capital. The pyramid is no upside down with inventory at the top. When we examine the pipeline theory of working capital, we will find that pipeline of the productivedistributive system of an enterprise consists of only inventories which, at different stages, take on different names like work-in-progress, finished goods, accounts receivable, cash balance, etc. Working capital structure is being so designed today in efficient organizations as to take care of this fundamental liquidity of an enterprise with zero or even negative net working capital. Firms may have an optimal level of working capital maximizes their value. Large inventory and a generous trade credit policy may lead to high sales. Larger inventory reduce the risk of the stockout trade credit may stimulate sales because it allows customers to assess product quality be for paying (Long et al. 1993) and (Deloof and Gegers, 1996). Because suppliers my have significant cost advantages over financial institutions in providing credit to there customers, it can also be an 8 inexpensive source of credit for customer (Peterson and Rajan, 1997). The flip side of granting trade credit and keeping inventories is that money is locked up in working capital. 1.4 Working Capital Management and the Researchers’ View The corporate finance literature has traditionally focused on the study of long-term financial decisions. Researchers have particularly examined investments, capital structure, dividends or company valuation decisions, among other topics. However, short-term assets and liabilities are important components of total assets and needs to be carefully analyzed. Management of these short-term assets and liabilities necessitates a careful investigation since the working capital management plays an important role for the firm’s profitability and risk as well as its value (Smith, 1980). Firms try to keep an optimal level of working capital that maximizes their value (Howorth and Westhead 2003, Deloof 2003). In general, from the perspective of Chief Financial Officer (CFO), working capital management is simple and a straightforward concept of ensuring the ability of the organization to fund the difference between the short term assets and short term liabilities (Harris 2005). However, a “Total” approach should be followed which cover all the company’s activities relating to vendor, customer and product (Hall 2002). In practice, working capital management has become one of the most important issues in the organizations where many financial executives are struggling to identify the basic working capital drivers and the appropriate level of working capital (Lamberson 1995). Consequently, companies can minimize risk and improve the overall performance by understanding the role and drivers of working capital. Working capital management policies have been divided into two categories by Weinraub and Visscher (1998). A firm may adopt an aggressive working capital asset management policy with a low level of current assets as percentage of total assets. On the other hand, aggressive working capital financing policy uses high level of current liabilities as percentage of total liabilities. Excessive levels of current assets may have a negative effect on the firm’s profitability whereas a low level of current assets may lead to lower level of liquidity and stock-outs resulting in difficulties in maintaining smooth operations (Van Horne and Wachowicz 2004). Moreover, aggressive working capital financing policies that utilize higher levels of normally lower cost shortterm debt increase the risk of a short-term liquidity problem. Therefore, more aggressive working capital policies are associated with higher return and higher risk while conservative working capital policies are concerned with the lower risk and return (Carpenter and Johnson 1983, Gardner, Mills and Pope 1986, Weinraub and Visscher 1998). 9 The main objective of working capital management is to maintain an optimal balance between each of the working capital components. Business success heavily depends on the ability of financial executives to effectively manage receivables, inventory, and payables (Filbeck and Krueger 2005). Firms can reduce their financing costs and/or increase the funds available for expansion projects by minimizing the amount of investment tied up in current assets. Most of the financial managers’ time and effort are allocated in bringing non-optimal levels of current assets and liabilities back toward optimal levels (Lamberson 1995). An optimal level of working capital would be the one in which a balance is achieved between risk and efficiency. It requires continuous monitoring to maintain proper level in various components of working capital i.e. cash receivables, inventory and payables etc. The optimal level of working capital is determined to a large extent by the methods adopted for the management of current assets and liabilities. It requires incessant management to maintain proper level in various components of working capital i.e. cash receivables, inventory and payables etc. In general, current assets represent important component of total assets of a firm. A firm may be able to reduce the investment in fixed assets by renting or leasing plant and machinery, whereas, the same policy cannot be followed for the components of working capital. The high level of current assets may reduce the risk of liquidity associated with the opportunity cost of funds that may have been invested in long-term assets. The impact of working capital policies is highly important, however as per the available literature, no empirical research has been carried out to examine the impact of working capital policies on profitability and risk of firm. These profitability assumptions suggest maintaining a low level of current assets and a high proportion of Current liabilities to total liabilities. This strategy will result in a low, or conceivably negative, level of a working capital. Offsetting the profitability of this strategy, however, is the increased risk to the firm. In determining the appropriate amount, or, level, of current assets, management must consider the trade- off between profitability and risk. Many surveys have indicated that managers spend considerable time one-day-to-day problems that involve working capital decisions. One reason for this is that current assets are short-lived investment that are continually being converted into other assets types (Rao 1989). For example, cash his used to purchase inventory items eventually become accounts receivable when they are sold on credit; and finally, the receivable are transformed into cash when they are collected. With regard to current liabilities, the firm is responsible for typing these obligations on a timely basis. The ability to match short term obligations has only improved from a liquidation perspective and 10 not from a going concern approach (Shulman and Dambolena, 1986). A firm’s net working capital is also often used as a measure of its liquidity position. That is, it represents the risk or probability that a firm will be unable to meet is financial obligations as they come due. Therefore, the more net working capital a firm as, the greater its ability to satisfy credits, demands. Moreover, because net working capital serves as an illiquid risk measure the firm is net working capital position will affect its ability to acquire debt financing. For example, commercial banks often impose minimum working capital constraint in their loan agreements with firms similarly; bond indentures may contain such restrictions. Due the credit squeeze, the problem of working capital management has acquired special importance. The leading policies of commercial banks have under revolutionary change in the recent periods. The shift in the emphasis from security to purpose of advance has affected a large number of borrowers. Beside this, norms for inventory and debtors have also been laid down. To aim at a sense of discipline in the working capital management all these developments have been introduce. The level and nature of business firm investment depend on the firms’ product types, its operating expenses, and management policy. As sales increase over time, more cash, receivable, and investment with usually are needed. Even within a firm’s normal operating cycle, seasonal sales patterns cause the level of current assets to be relatively high or low at any particular point. Moreover, the firms’ credit and inventory policies, and how efficiently it manages its current assets, can drastically affect a firms working capital need. For example, a conservative toy manufacturer may maintain a high level of inventory to satisfy unexpected demands or to hedge against delays in acquiring new inventory. A more aggressive or more efficient toymaker, on the other hand, may function with a much lower investment in inventories. Current assets provide the liquidity necessary to support the realization of the expected returns from firms’ long-term investments. The cash flows associated with long-term investments are uncertain and irregular, and it is the non synchronous nature of the cash flows that makes working capital necessary. Otherwise, a mismatch between cash inflows and outflows could a liquidity crisis. This, in turn, could disrupt or reduce the long-term returns expected from a firm's fixed asset investment. Current assets therefore act as a buffer to reduce the mismatch between cash outflows for goods and services and the cash receipts generated by the sales revenues. 11 1.5 Significance of the Management of Working Capital For the success of an enterprise proper management of working capital is very important. It aims at protecting the purchasing power of assets and maximizing the return on investment. The success of operations of a firm is determined to a large extent by the method administration of its current. It requires continuous management to maintain proper level in various components of working capital i.e. cash, receivables and inventory etc. In establishing proper proportions, cash and financial budget may be very useful. Sales expansion, dividend declaration, plant expansion, new product line, increased salaries and wages, rising price levels etc. put added strain on working capital maintenance. Due the poor management and lack of management skills, business fails certainly. Shortage of working capital, so often advanced as the main cause of failure of industrial concerns, is nothing but the clearest evidence of mismanagement which is so common. The prime object of management is to make profit. This accomplishment in most business depends largely on the manner in which their working capital management usually is considered to involve the administration of current assets of a company namely, cash, account receivables and inventory. Administration of fixed assets falls within the realm of capital budgeting while the management of working capital is a continuing function which involves control of every day and flow of financial resources circulating in the company in one form or the other. In turn these decisions are influenced by the trade- off that must be made between profitability and risk. Lowering the level of investment in current assets, while still being able to support sales, would led to an increase in the firm is return on total assets. Smith (1980) first signaled the importance of the trade offs between the dual goals of working capital management, i. e., liquidity and profitability. To the extent that the explicit costs of short-term financing are less then those of intermediate and long-term financing, the greater the proportion of short-term debt to total debt, the higher is the is the profitability of the firm. From another perspective, the current assts of a typical manufacturing firm accounts for ever half of its total assets. For a distribution company, they account for even more. Excessive levels of current assets can easily result in a firm is realizing a substandard return on investment. However firms with too few current assets may incur shortages and difficulties in maintaining smooth operations (Van-Horne and Wachowicz, 2004). For small companies current assets and liabilities are the principal source of external financing. These firms do not have access to the longer term capital markets, other than to acquire a mortgage on a building. The fast growing but a larger company also makes use of current liabilities financing. For these reasons the financial manager and staff devotes a considerable portion of their time to 12 working capital matters. The management of cash, marketable securities, receivable, payables, accruals, and other means of shot-term financing is the direct responsibility of a financial manager, only the management of inventories is not. Moreover, these management responsibilities require continuous day to day supervision. Unlike dividend and capital structure decision, one cannot study the issue, reach a conclusion, and set the mater aside for many months to come. Thus working capital management is important, if for no other reason then the proportion of the financial managers’ time that must be devoted to it. More fundamental working capital management decisions have its effects on the company is risk return, and share price. While managing working capital, two fundamental decisions the firm must be taken into the consideration are: Firstly, how much to invest in the current assets to have an optimal mix of current and fixed assets. Secondly, an appropriate mix of short-term and long-term financing options used to support the investments in current assets must be looked into. In turn, the above discussed tow decisions are influenced by the trade off that must make between profitability and risk. Return on assets can be increased by lowering the level of investment in current asset, while still being able to support sales. 1.6 Research Objectives The present study investigates the relationship of the aggressive and conservative working capital asset management and financing polices and its impact on profitability of 204 Pakistani firms listed on Karachi Stock Exchange for a period of 1998-2005. This research: • Examines whether significant differences exist among the working capital practices of the firms across different industries, • Confirm whether these aggressive or conservative working capital policies are relatively stable over the period of time, • Validates the relationship between working capital asset management and financing policies firms and investigates how a working capital asset management policy corresponds to working capital financing policy. • The impact of aggressive and conservative working capital asset management and financing policies profitability of the company by using various profitability measures based on accounting data and market values. 13 • Finally, to confirm the findings if Carpenter and Johnson (1983), the study has investigated the impact of working capital policies on the financial and operating risk of firms operating in Pakistan. Therefore, it is hoped that this study will contribute to better understand these policies and their impact especially in the emerging markets like Pakistan. The remaining portion of the document is organized as follows: Chapter two reviews the relevant literature for the theoretical and empirical work on working capital management and its effect on profitability. Chapter three presents the research methodology and frame work which includes sample and the variables used for the analysis purpose. Chapter four portrays and discusses the data analysis inferred by applying some statistical techniques. Finally, Chapter five deals with the conclusion and recommendations the study reports. 14 Chapter 2 LITERATURE REVIEW & HYPOTHESES Many researchers have focused on financial ratios as a part of working capital management; however, very few of them have discussed the working capital policies in specific. Some early work by Gupta (1969) has focused on exploring the relationship between industries, size and growth effect on the financial structure of American manufacturing companies for a period of 1961-62. A large sample of 173,000 manufacturing corporations covering 21 SIC two-digit industries, classified into 13 categories according to their size were examined. For the purpose of analysis, four categories of financial ratios i.e. profitability, activity, leverage and liquidity were used. By applying the Spearman’s rank correlation, the study concluded that firms with small size and high growth tend to have lower liquidity ratios whereas large firms with lower growth rates might have high liquidity ratios. The patterns of financial ratios were different across various industry groups and were tend to be stable over a shorter period of time of 1961-1962. In a subsequent study, Gupta & Huefner (1972) used hierarchical cluster analysis to examine the descriptive or representative power of financial ratios with the basic industry attributes. The study covered twenty manufacturing industries as classified by Income Statistics data published by the Interval Revenue Services. For each industry, several financial ratios were calculated and clusters analysis was applied to those ratios. The study reported that differences in financial ratios do exist across the different industries. Moreover, assets ratios were related to industry characteristics both in terms of individual industries as well as industry groups. However, when aggregate assets turnover ratios were used, the inter-industry differences tend to disappear. The preliminary work on financial ratios has been done by Pinches et al. (1973) who developed and tested the empirical classifications of financial ratios as well as the stability of ratio groups over the longer period of time from 1951 to 1969. The sample included 221 firms from the various industrial sectors of United States and forty-eight financial ratios were calculated for the classification purpose, which were further normalized through obtaining common log transformation of financial ratios. The study used R factor analysis to classify financial ratios into similar groups whereas differential R factor analysis was employed to determine the degree of stability over the longer time period. The results of R factor analysis yielded seven classifications of financial ratios for the sample firms; return on investment, capital intensiveness, inventory intensiveness, financial leverage, receivable intensiveness, short-term liquidity and cash position. Furthermore the results of 15 differential R factor analysis suggested that the composition of these financial ratios into seven classifications were reasonably stable over the longer period of study. Another perspective of financial ratios was studied by Walker & Petty (1978) by analyzing the differences among the financial management policies and practices of 31 large and 31 small public firms in United States from the different industrial sectors. Five dimensions of financial operations of a firm were analyzed to distinguish between large and small firm financial management practices; liquidity, profitability, financing, business risk and dividend policy indicators. The statistical methods employed were F-test and multivariate discriminant analysis. The study concluded that small and large corporations do have different financial management characteristics. Moreover, small size firms can earn more profits than large corporations because of the efficient management of firm’s assets. The larger firms have greater liquidity than smaller firms due to greater access to the financial markets and wide variety of available financing options. Johnson (1979) extended the work of Pinches et al. (1973) and Pinches et al. (1975) by finding the cross sectional stability of financial ratios for primary manufactures and retailers in U.S. The research was based on sixty-one financial ratios calculated using the annual financial data for a period of 1972 to 1974. In addition to seven classifications of financial ratios found by Pinches et al. (1973) study, the principal component analysis identified decomposition measures factor, which included assets decomposition, equity decomposition and non-current items decomposition of balance sheet. Moreover, canonical co-relational analysis confirmed that the eight factors of financial ratios possessed a high degree of cross-sectional stability across the two industries for the period of study. Chen and Shimerda (1981) presented a summary of the financial ratios used in a number of early studies, which used the financial ratios for analysis and prediction purposes. It is been noted by the authors that there was an abundant 41 different financial ratios, which were found useful in the earlier studies. They reconciled the factors in the earlier studies into financial leverage, capital turnover, return on investment, inventory turnover, receivables turnover, short-term liquidity, and cash position and identified ten financial ratios which were representative of their seven factors. After a principal component factor analysis of 39 ratios of the Pinches et al. (1975), the study concluded that there was a high instability in always selecting the financial ratio with the highest absolute factor loading as the representative financial ratio for the observed factors. 16 Furthermore, Scott & Johnson (1982) provided an insight into the financing policies of large American corporations. The data was collected through 25-items questionnaire mailed to chieffinancial officers of Fortune 1000 firms. The usable and complete questionnaires were returned by 212 CFOs with a response rate of 21.2%. The results indicate that 90% of the respondents used financial leverage ratios to make the financing decisions. The most important ratios ranked by CFO’s were long-term debt to total capitalization ratio, times interest earned and long term debt to net worth whereas the firms used book values for computing the ratios rather market values. Moreover, 53% of the respondents confirmed that industry benchmarks influence their decisions of financing choices. In the continuity of earlier studies, Gombola & Ketz (1983) analyzed 783 manufacturing and 88 retail firms to examine the intra-industry stability of financial ratio patterns for a period of ten years from 1971 to 1980. The set of 58 financial ratios studied by Pinches et al. (1973) was re-examined in the study. Classification patterns among financial ratios were developed with the help of factor analysis varimax rotation procedure both for retailing and manufacturing firm sectors for each of the ten years of study. The findings of Pinches et al. (1973) were supported with two additional financial ratios factor i.e. cash expenditures and cash flow. Moreover, the study also found that both the retailing and manufacturing firm sectors exhibited cross-sectioned stability across years as well as time series stability within industries. The study of Pinches et al. (1973) has been replicated in Europe by Ezzamel et al. (1987) who reported the empirical evidence on the types and the extent of long-term stability in the financial patterns for U.K. manufacturing companies. The data about the financial statements of 1434 manufacturing companies for a period of 1973-1982 has been used for the study. The principal component factor analysis identified five broad categories of financial performance of UK companies; total fund structure, profitability, working capital position, liquidity and assets turnover. The identified financial patterns were found to be partly stable over the study period as per the results of differential R factor analysis except working capital position, which was significantly stable at higher level of significance. Pandey and Bhat (1990) provided regional evidence on empirical classification of financial ratios and examined the intertemporal stability/change of classifications of financial ratios in Indian manufacturing companies. Factor analysis, differential R factor analysis, and correlation percentage absolute deviations have been used as statistical methods. The study found eleven financial ration factors i.e. return on investment, sales efficiency, equity intensiveness, short-term liquidity, current assets intensiveness, cash position, activity, earnings appropriation, financial structure, interest 17 coverage, and long-term capitalization. Furthermore, differential R factor analysis confirmed that these eleven financial ratios patterns were reasonably stable over the period of study. In addition to the study of Gombola & Ketz (1983), Chu et al. (1991) analyzed acute-care hospitals to explore whether the hospital financial ratio groups differ from industrial firm financial ratio groups and whether these groups remain stable over the period of study. The financial data about 113 acute-care hospitals was use for a period of five years from 1983 to 1987. Varimax rotated factors analysis has been used to classify 31 selected financial ratios into independent groups. The results identified seven industrial ratio groups as with those of industrial firms, however, a consistently independent factors of working capital flow indicated that hospital working capital measure do differ from other industrial firms. Furthermore, the eight ratio groups did not remain stable throughout the study period. The reason for this unstable pattern of financial ratios might be due the impact of financial constraints on hospital finances. The Medicare Prospective Payment System was gradually implemented during the period of study, therefore, financial ratio patterns did not remained stable over the period. Martikainen and Ankelo (1991) reported empirical evidence on the relationship between the stability of financial ratio patterns and corporate failure of firms operating in an emerging market of Finland. The study used the data of 20 failed and 20 non-failed firms for a period of five years before actual failure and twelve financial ratios were used for the analysis purpose i.e. Net Income to Sales, Return on Investment, Return on Assets, Quick Ratio, Current Ratio, Quick Assets to Liabilities, Equity to Capital, Debt to Sales, Net Interest to Sales, Receivable Turnover, Inventory Turnover and Payable Turnover. Principal component factor analysis with varimax rotation has been used to identify the financial patterns of failed and non-failed firms whereas relative stability of these financial patterns in failed and non-failed firms was found by applying transformation analysis. The results indicated that the financial patterns of failed firms were unstable than those of non-failed firms and this unstable pattern was observed from the beginning of the study period i.e. five years before the actual failure of firms. In their later study, Martikainen et al. (1994) applied transformation analysis to compare the financial ratio structure between industries for 74 failed and 74 non-failed firms in Finland. The industry effects on financial ratios were investigated by using 16 financial ratios for small and medium sized Finnish firms. Four ratio classifications were found for three industries through principal component analysis and varimax rotation. The results indicated that there was a significant industry effect on the classification patterns of financial ratios. Furthermore, this industry effect was 18 stronger for working capital ratios and efficiency ratios and this relationship remained significant in both small and large Finnish firms. In literature, there is a long debate on the risk/return tradeoff between the different working capital policies. More aggressive working capital policies are associated with higher return and higher risk while conservative working capital policies are concerned with the lower risk and return. In this regard, Belt (1979) highlighted the determinants of working capital policies and the rewards & risks of an aggressive working capital policy. The author claimed that there might be two real determinants of the level of net working capital of a firm. The first determinant is the operational aspect that describes how much liquidity is needed in the current assets of the firm whereas the second determinant is the deferability of current liabilities of the company, which is the ability to postpone or delay the payments to creditors for some period. The author also asserted that the rewards and risks of an aggressive working capital policy vary between industries and within industries. Generally, the benefits might be attained by reducing the holding costs of fast moving inventory, lower collection costs associated with lower level of receivables and somewhat less costly short-term debt. However, higher returns of an aggressive working capital policy are often associated with risk of liquidity as well. The use of large level of current liabilities, i.e. aggressive financing policy of working capital increases the chances of financial embarrassments that can lead to corporate failure and bankruptcy. Based on the theory of Belt (1979), Nunn (1981) explored empirically the various strategic determinants of permanent working capital level on product line perspective. By applying the crosssectional of regression analysis, the study developed a model consisting of strategic determinants that explain why working capital differs from business to business. The sample consisted of 400 diverse businesses for a period of eight years from 1971-1978. Principal component and varimax rotation factor analysis was applied to identify 166 explanatory variables of working capital requirements for different businesses. A multiple regression model was built on 43 independent factors identified by factor analysis and dependant variable i.e. working capital to sales, working capital level is influenced by production, selling and accounting related variables as well as industry characteristics. In addition, Carpenter & Johnson (1983) empirically investigated the relationship between the level of current assets and the operating risk of firms. The sample firms included were the large firms from various industrial sectors in the United States. The sample data was collected for a period of four years i.e. 1978-1982. The regression analysis showed no significant linear relationship between the level of current assets and revenue systematic risk or operating systematic risk. However, some 19 indications of a possible non-linear relationship were found which were not highly statistically significant. A primary research by Lamberson (1989) provided an insight into the importance and utilization of financial analysis and working capital management by small manufacturers in U.S. A questionnaire was mailed to chief financial officers of 477 small firms in the southern region of U.S. The 85% of the respondents indicated that they use ratio analysis for financial planning on monthly basis. Working capital management was ranked important and most important by 90% of the respondents. The importance of working capital management for small firms was, perhaps, due to their limited access to capital markets and finance providers. Accounts receivables and inventory management among the various components of working capital were ranked the most important while cash management was ranked least important by small manufacturers. Gentry et al. (1990) introduced a new concept of weighted cash conversion cycle in order to examine the working capital management of firms. The weighted cash conversion cycle measures the weighted number of days the funds are tied up in the accounts receivables, accounts payables and inventories less number of days payments are deferred to suppliers of the firms where the weights are calculated by dividing the amount of cash tied up in each component of working capital by the final value of product. The proposed weighted cash conversion cycle is an aggregate measure of the amount and speed that the funds flow through working capital accounts of a firm and concentrates on the real resources committed to the total working capital process. Belt & Smith (1991) compared the working capital management practices of Australia and United States with two earlier surveys conducted in United States by Smith & Sell (1980) and Belt and Smith (1989). A mail questionnaire has been used to collect the data from 144 Australian firms selected from Australian Business “Top 500 Companies”. The final response was received from thirty-nine firms, which were categorized on the basis of size and profitability with a response rate of 27.1%. The results indicated that about 95% of the respondents had a formal or informal working capital policy as in the previous surveys. Two-third of the firms managed working capital on situational basis rather than risk-avoiding or risk-accepting factors, which was 28% only. The most important factors of working capital management in Australia and United States was speeding the collection of receivables and minimizing investing in inventory. Moreover, the working capital management in Australia was found to be more centralized than United States. On average, the results were consistent with previous stories of Smith & Sell (1980) and Belt & Smith (1988). 20 Kim et al. (1992) dealt with two issues in their study; what were the objectives of working capital management by Japanese manufacturers in the United States and; to identify the major options of short-term funds. The necessary data was obtained through a detailed questionnaire mailed to financial managers of 326 Japanese manufacturers operating in the United States. The received response was about 94 firms with a response rate of 29%, which was quite reasonable. The data indicated that most important objective of working capital management for Japanese firms in US was to provide the current assets and liabilities to support the expected sales. The second most important objective was to evaluate changes in investment decisions in current assets and to minimize the cost of short-term credit. More than 70% of times, Japanese firms used outside financing as major source of short term financing. About 90% of the respondents indicated that they prefer financing either from Japanese banks in U.S or parent company in Japan which is a strong indication of Japanese Firm’s involvements in “Kieretsu” which indicate the close link of Japanese firms with their parent firms. For the first time, Soenen (1993) investigated the relationship between the net trade cycle and return on investment in U.S firms. The study also checked the impact of cash conversion cycle across industries on the profitability of firms. The annual financial data for 2000 firms and 20 industries had been used for analysis purpose for the period of 1970-1989. The firms were divided into four quadrants on the basis of the median values of net trade cycle and return on assets. A chi-square test was applied to measure the association between the quadrants of firms, which indicated negative relationship between the length of net trade cycle and return on assets. Furthermore, this inverse relationship between net trade cycle and return on assets was found different across industries depending on the type of industry. A significance relationship for about half of industries studied indicated that results might vary from industry to industry. Empirical evidence on traditional trade credit theories has been presented by Long et al. (1993) using a large sample of US manufacturing firms. The data has been collected for three years i.e. 1985-1987 of all industrial firms with SIC Code 2000 through 3999. Using univariate and pooled cross-sectional regression analysis, the results supported the product quality theory that smaller firms with longer production cycle extend more credit than larger firms having superior quality of products. The evidence also suggested that these practices of extending trade credit varied both within and across industries. Moreover, the results indicated that extending more credit might be financed through short-term borrowings and payables. 21 The financial management techniques employed by large firms of Fortune 500 corporations of 1991 have been surveyed by Gilbert and Reichert (1995). Chief financial officers of 151 companies completed and returned the questionnaires with a quite reasonable response rate of 30.2%. Comparing the responses with another survey of fortune 500 firms in 1980 and 1985, the authors concluded that majority of the firms used financial management and working capital techniques for their financial planning. Accounts receivables management and inventory management models were adopted by almost 60% of the respondents as sophisticated working capital management techniques. Furthermore, the usage of these working capital management techniques has been increased in 1991 as compared to 1980 and 1985. Lamberson (1995) studied empirically how small firms respond to changes in economic activities by changing their working capital positions and level of current assets and liabilities. Small firms were expected to increase the level of current assets and liabilities as the economy expands. The hypothesis was tested on 50 small firms in U.S. and the data about financial statements and economic activity was collected from Moody’s industrial manual for a period of 1980-1991. Current ratio, current assets to total assets ratio and inventory to total assets ratio were used as measure of working capital while index of annual average coincident economic indicator was used as a measure of economic activity. Correlation analysis was conducted to check the relationship between the economic expansion/contraction and the level of working capital while the significance of relationship has been measured by t test. Contrary to the expectations, current ratio and quick ratio increased during expansion period while the other two ratios remained relatively stable during the period of economic expansion. Overall, the study found that there is very small relationship between charges in economic conditions and changes in working capital. Rafuse (1996) analyzed the different aspects of optimal working capital management and its components. His article argued that attempts to improve working capital management by delaying the payments to creditors is an inefficient and ultimately damaging practice, both to its practitioners and to economy as a whole. The study claimed that altering debtors and creditors levels would rarely produce any net benefit rather it will harm the sales or the financing options of the firm. The study proposed that stock reduction strategies based on some “Lean Production” techniques might be far more effective than any other single working capital management technique. Reducing stock would produce major financial advantages by improving cash flows, reducing operational level costs of inventory and reducing capital spending. Moreover, it is further argued that the “Lean” world-class companies are systematically better than their counterparts in every important aspects and characteristics that makes a company “Lean” is low stock levels. 22 In order to validate the results found by Soenen (1993) on large sample and with longer time period, Jose et al. (1996) examined the relationship between aggressive working capital management and profitability of US firms. Cash conversion cycle (CCC) has been taken as a measure of working capital management where a shorter cash conversion cycle represents the aggressiveness of working capital management whereas pre-tax return on assets and equity has been used as profitability measures. The data has been collected for a period of twenty-four years from 1974 through 1993 for 2,718 firms. The relationship between the cash conversion cycle and profitability measures has been tested through cross-sectional regression analysis. The results indicated a significant negative relationship between the cash conversion cycle and profitability indicating that more aggressive working capital management is associated with higher profitability. The shorter the cash conversion cycle, greater the return on assets and return on equity. Peel & Wilson (1996) surveyed 250 small U.K. manufacturing and service firms to look into the working capital and financial management practices. A questionnaire was mailed to managing directors of small firms located in north & west of Yorkshire in 1993. The response of 84 companies indicated that, on average, 80% of small U.K. firms were using the quantitative working capital and financial management techniques to manage the companies’ assets. A regional study by Pandey and Parera (1997) provided an empirical evidence of working capital management policies and practices of the private manufacturing companies in Sri Lanka. The information and data was collected through questionnaires and interviews with chief financial officers of a sample of manufacturing companies listed at the Colombo Stock Exchange. The authors concluded that most companies in Sri Lanka have informal working capital policy and the managing director plays a major role in formulating formal or informal policy for working capital management. Moreover, company size has an influence on the overall working capital policy whether it is formal or informal and approach (conservative, moderate or aggressive). Company profitability and working capital policy influenced the payable management and working capital finance respectively. Current and cash budget are major techniques of working capital, planning and control. Company profitability has an influence on the methods of working capital planning and control. The sample companies considered sometimes working capital changes when they evaluate capital budgeting decisions. Most of the studied companies used bank interest rate as a hurdle rate for evaluating the working capital changes. Furthermore, a comparison of the working capital practices of the Sri Lankan manufacturing companies with the USA manufacturing companies revealed a lot of similarities. The basic difference is in terms of the use of computerized system and the opportunity to invest surplus cash in the money market instruments. 23 Smith & Begemann (1997) examined the trade off between the liquidity and profitability of firm by investigating the association between return on investment and alternative measures of working capital. The study used the data bank of Bureau of Financial Analysis for 135 firms listed in Johannesburg Stock Exchange (JSE) for a period of 1984 to 1993. By applying the Pearson Chisquare test, the study found significant positive association between accounts receivables, accounts payables and inventory turnovers with return on investment. The step-wise regressions analysis produced R2 of 52% and corroborated the finings of chi-square test. The alternative measures of working capital management exhibited strong negative correlation with return on investment as 5% level of significance. Bhattacharyya and Raghavacahari (1997) examined the determinants of effective working capital management in 72 large Indian companies. A questionnaire was mailed to the mangers to view the perceptions in their working capital management process in their respective organization. The Discriminant analysis indicated that the prime determinants of effectiveness of working capital management in order to their relative importance were: 1) profit after tax as percentage of sales, 2) sales as number of times to total assets, 3) quick assets as percentage of current liabilities and 4) receivables as numbers of day’s sales. The authors recommended that the financial managers and analysts should pay more formal and explicit attention to these four factors while conducting their financial analysis. Continuing with their early attempt, Shin & Soenen (1998) empirically examined the relationship between efficiency of working capital management and the corporate profitability of firms by taking net trade cycle as a measure of working capital management. The study used 58,985 firm years record for a period of 20 years from 1975 to 1994. The Pearson linear and Spearman rank correlation analysis indicated a significant inverse relationship between the net trade cycle and accounting measure as well as market measure of profitability. The pooled and cross sectional regression analysis confirmed the results of correlation analysis that firms with shorter trade cycle earned more profits. However, the negative relationship between the current ratio and profitability indicate a trade off between liquidity and profitability of a firm. Therefore, firms can improve corporate profitability by enhancing efficiency of working capital management by keeping in view the liquidity of firms. Furthermore, regression analysis also confirmed the impact of industry on a firm’s investment in working capital. The results confirmed the findings of Hawawini et al. (1986) that industry benchmarks must have been adhered by firms when setting their working capital policies. 24 Maxwell et al. (1998) compared the short-term financial management practices of U.S firms with previous study conducted by Gitman et al. (1979). The objective of the paper was to find the similarities and differences between the two surveys as well as the financial management practices of U.S and Non-US Firms. A 25-item questionnaire was mailed to chief financial officers of a stratified sample of 2075 firms in 16 nations of European Union, North America and Pacific Region. The response rate was very low i.e. 6.4% as only 133 questionnaires were returned. Analysis has revealed a significant change in the short-term financial management practices since 1979 in U.S. Firms. Moreover, the study also suggested that significant differences exist in the techniques and polices of short-term financial management among the U.S firms and foreign firms. The differences between 1979 survey and current study as well as between domestic and foreign firms were most likely caused by differences in economic and technological expertise and changes across time and competing countries. A qualitative and case study approach has been applied by Ooghe (1998) to investigate into the financial management practices of Chinese firms in the Shanghai region. The financial manages of 16 diverse firms from different industrial sectors in Shanghai were interviewed on the basis of an extensive questionnaire. The results of interview revealed that many firms do not have formal working capital policies especially for accounts receivables and payables. Firms faced big problem in the collection of receivables due to the lack of clear credit and collection policy. The amounts in accounts payable were sometimes very high and proper payment systems were not followed. The issue of aggressive and conservative working capital policies on empirical basis has been discussed by Weinraub and Visscher (1998) who analyzed working capital policies of 126 industrial firms from 10 diverse industrial groups using quarterly data for a period of 1984 to 1993. The primary objective was to observe the differences in working capital policies as well as the long-term stability of working capital policies over time. Current assets to total assets ratio and current liabilities to total asset ratio were used as working capital investment and financing policies. Analysis of Variance (ANOVA) and Tukey’s HSD tests clearly indicate significant differences in working capital policies across various industries. Rank order correlation analysis confirmed the stability of these polices over ten year period of time. Furthermore, the negative relationship between industry working capital investment and financing policies indicated that when relatively aggressive working capital investment policies were followed, they were balanced by relatively conservative working capital financing policies. 25 Khoury et al. (1999) extended the work of Smith and Sell (1980), Belt and Smith (1991) by comparing the working capital practices of Canadian firms with United States and Australian firms. The 45-Items questionnaire was mailed to 350 firms randomly selected from 10 industries within the BOSS database obtained from the Ministry of Industry, Science and Technology. Only 7% of the respondents had formal working capital policy, which is much smaller than the previous studies. The 28.5% of Canadian firms have cautious working capital policy while only 10.2% of the respondents have an aggressive working capital policy. On average, the results were not much different from the previous survey conducted in U.S and Australia. Anand & Gupta (2002) established then quantitative benchmarks for working capital performance evaluation of Corporate India. These included days operating cycle, days working capital and cash conversion efficiency. The basic thrust of the paper was to estimate these three benchmarks for firms and industries as well as to observe the differences among industries and over the period of time. The 427 companies of S&P 500 companies of corporate India were analyzed for the period of 1999-2001. The results indicated that the working capital performance of corporate India varies across industries based on the above-mentioned measures of working capital. Moreover, the measured values of working capital changed over time and were not stable across the period of study. To provide empirical evidence from an under-developed market, Sathyamorthi (2002) analyzed the working capital practices of selected co-operatives in Botswana for a period of 1994 to 1997. The study looked at how current assets are financed and to establish a trend over the period of time. The financial ratios were used to obtain a correct picture of the working capital movements in cooperative societies. Measures of central tendency and dispersion were applied to the working capital ratios. The results indicated that, on average, the selected co-operatives in Botswana adopted an aggressive approach during the study period in terms of working capital asset management. Moreover, the co-operative societies adopted a conservative policy to finance the current assets in all the four years of study. Raman & Kim (2002) used a case study approach to quantify the relationship between inventory carrying costs and a firm’s target stock out costs. The study was motivated by the inventory management and stock out problems at North Co., a school uniform producer in U.S. Using the linear programming approach, the authors suggested that firms with high working capital costs should target substantially higher stock out costs and higher capacity levels in that particular industry 26 Hall (2002) introduced a “Total” approach to working capital management and argued that this “Total” approach covered all the company’s activities relating to vendor, customer and product. Accounts receivables management was termed as Revenue Management, which included searching for customers to collecting cash form them for credit sales. Inventory management, also named as Supply Chain Management, started from the forecasting of the customer claimed and ended with the fulfillment of the forecasted demand. The third working capital component, account payables was proxied with expenditure management, included the whole process of purchasing from vendors to pay the cash. The study argued that this integrated or “Total” approach to working capital management would reduce inefficiencies in the business processes as well as improve firm performance. Howorth & Westhead (2003) examined the eleven working capital management routines of 343 small companies in UK through a mailed questionnaire. Principal component analysis and discriminate analysis reduced the number of working capital management routines form 11 to 3 and company types to 4 categories respectively. The multinomial logistic regression has been used to identify various independent variables that discriminate between the companies, which follow or did not follow working capital management routines. The results indicated that companies focusing on cash management were larger, younger in age, with fewer cash sales, more seasonality and more external finance. Firms focusing on stock management routines were smaller, younger with less external finance and longer production cycles. Credit management routines were focused by firms, which had lower profitability, more credit purchases & sales, and high growth firms. On the contrary, firms focusing least on any of working capital management routines were low growth, high profitable, having less external finance, fewer credit purchases & sales, having shorter production cycles and less sophisticated financial skills in general results. The model of Soenen (1993) has been used by Deelof (2003) to investigate the relationship between the working capital management and corporate profitability for a sample of annual data of 1009 large Belgian non-financial firms for the period of 1992-1996. The cash conversion cycle has been used as a comprehensive measure of working capital management, whereas gross operating income has been used as a measure of corporate profitability. In addition, size of the firm, sales growth, the financial debt and ratio of fixed financial assets to total assets were introduced as control variables. The results of Pearson correlation and ordinary least square regression confirmed the findings of Shin & Soenen (1998) and found a significant negative relationship between cash conversion cycle 27 and corporate profitability. It is suggested that the managers can create value for shareholders by maintaining the cash conversion cycle and its components to an optimal level. Eljelly (2004) empirically analyzed 29 Saudi joint stock companies for a period of 1996-2000 to examine the relationship between liquidity and profitability. The study used net operating income as dependent profitability measure and cash gap (cash conversion cycle) and current ratio as independent liquidity measures whereas the size of firms as measured by sales and industry effect has been controlled for detailed analysis. A strong negative relationship has been reported between the liquidity measures and net operating income by Pearson correlation and pooled regression analysis. The study further confirmed that cash gap produced more significant results at industry level than the current ratio. Moreover, the size is also affecting the profitability of firms and these results are stable over the period of study. The efficiency of working capital practices in Indian cement industry has been examined by Ghosh and Maji (2004) using some alternate measures of working capital management. Three measures; performance index of working capital, utilization index of working capital and efficiency index of working capital were used to measure the overall efficiency of Indian cement manufacturing firms. The data about 20 large cement industries was collected for 10 years from 1992-2001. The results indicated that Indian cement industry did not perform remarkably well during the study period in terms of working capital management. Industry average for efficiency index of working capital was greater than 1 for only 6 years out of 10 years of study. However, some of the sample firms improved their efficiency index during the study period but a high degree of inconsistency is found into working capital management practices. Another study by Teruel and Solano (2005) provided empirical evidence of impact of working capital management on profitability of small and medium sized Spanish firms. Cash conversion cycle along with its components has been taken as independent variables whereas return on assets has been used as dependent measure for profitability. The data set was consisted of 8,872 SMEs covering the period of 1996-2002 was obtained from ABADEUS database of Spain. A strong negative relationship between return on assets and cash conversion cycle along with its components i.e. days accounts receivables, days inventory and days accounts payable was indicated by correlation analysis. The multivariate regression analysis confirmed this negative relationship that shortening the cash conversing cycle, firms can generate more profits for shareholders. The regression results were found significant for negative relation between return on assets and inventory turnover as well as days accounts receivables. However, impact of delaying payment to 28 suppliers on return on assets remained inconclusive because it was not significant at 5% level of significance. In order to confirm the findings of earlier studies, Filbeck and Krueger (2005) analyzed the working capital efficiency of firms as per the ranking made by CFO magazine in the annual working capital surveys for 1996-2000. The study examined the differences in working capital efficiency across industries as well as stability of working capital measures across time. The differences in working capital efficiency across industries were evaluated by using Analysis of Variance (ANOVA) test. The results of ANOVA test suggested that differences do exist among industries in respect of working capital measures i.e. days of working capital, inventory turnover, days payables and days sales outstanding. Furthermore, Kendall’s concordance coefficient indicated that the working capital measure very across time. However, these changes were consistent across industries to pressure industry ordering across time. On the other hand, Enyi (2005) examined the relationship between the operational size of the firm and the adequacy of the working capital requirements in Nigeria. Relative solvency ratio has been used to measure the level of working capital that can be considered adequate for the firm size and operational level. A relative solvency ratio greater than one was considered to be adequate for working capital level requirements relative to the operational size of the firms. The data has been collected from the annual published repots of 25 companies listed in Nigeria Stock Exchange together with the interviews of selected officials of the firms. T-test has been applied to compare the relative solvency ratio and return on capital employed as the performance measure of firms having relative solvency ratio greater than one with those that were less than one. The results indicated that firms having relative solvency ratio greater than 1 i.e. adequate working capital relative to its operational size perform better than firms who have inadequate working capital. Medeiros (2005) empirically tested the Michel Fleuriet’s advanced working capital management model by taking a sample of 80 Brazilian firms listed at Sao Paulo stock exchange for a period of 1995-2002. The Fleuriet’s model was presented in Brazil in 1980 for advanced analysis of working capital management. The basic thrust of the model was that it divided the current assets and liabilities into current financial and current operating assets and liabilities respectively. Fleuriet claimed that current financial assets and current financial liabilities were erratic and not related to firms operations; however, this model was not tested on empirical grounds. This study tried to validate model by investigating into the relationship between current financial assets and liabilities as well as current asset and liabilities as whole with the net operating revenues of firms. The Pearson correlation and cross-sectional regression analysis confirmed that there is strong positive 29 relationship between firms operations and current financial assets and liabilities as well as current operating assets and liabilities. Moreover, panel data regression results further confirmed the expectations and, hence, rejected the Fleuriet’s model of dynamic working capital management, which was considered to be one of the advanced models of financial management in Brazil since 1980. From another angle, Chiou et al. (2006) have analyzed the determinants of working capital management by using net liquid balance and working capital requirements of a firm as measures of working capital management of a firm. The paper explored that how working capital management of a firm is influenced by the different variables like business indicators, industry effect, operating cash flows, growth opportunity for a firm, firm performance and size of firm. Using Taiwan’s TEJ database, 19180 quarterly observations have been collected for a period of 1996 to 2004. Net liquid balance was being affected by economic recession, operating cash flow and growth opportunities of firm positively and significantly except growth which was not found to be statistically significant. Whereas, firm cycle, leverage, age of the firm, return on assets and firm size were having negative and statistically significant relationship with the net liquid balance. Coming towards working capital requirements, economic recession, age and firm size were relating to working capital requirements positively and significantly, whereas, cycle, leverage, operating cash flow, growth and return on assets were having significant negative relationship with firm’s requirements of working capital. The result showed that firms operate on a loose working capital policy in the times of economic recession because it is hard to acquire external capital during recession so a relatively higher level of liquid assets is maintained. The results of leverage are consistent of pecking order theory that firm is supposed to maintain a higher debt ration where its working capital is depleted. Companies may get external borrowings instead of issuing securities with relatively low cost. The large companies are found to produce more net liquid balance from their operations. Moreover, companies with better performance and having higher return on assets tend to have a more conservative approach towards managing their working capital having more capital for contingencies. The study has also proved that when operating cash flow increases in a firm, the managers imply more efficient working capital management policy. The authors are in a view that the study has provided consistent results of leverage and operating cash flow for both net liquid balance and working capital requirements, however, variables like business indicator, industry effect, growth opportunities, performance of firm, and size of firm were unable to produce consistent conclusions for net liquid balance and working capital requirements of firms. The 30 similar study was also conducted by Nazir and Afza (2008) on a sample of Pakistani market and found somehow analogous results. More recently, Lazaridis and Tryfonidis (2006) investigated the relationship between working capital management and corporate profitability using quarterly date of 131 firms listed at Athens Stock Exchange of Greece. Cash conversion cycle has been used as a measure of working capital management whereas gross profit has been taken as profitability measure. The size of the firms as measured by natural log of sales, financial debt of firm and fixed financial assets to total assets ratio were used as control variables. Person correlation analysis showed a negative relationship between gross profit and cash conversion cycle as well as of the number of days accounts receivables and inventory while a positive relationship between gross profit and number of days accounts payables. In order to validate the robustness of correlation results, four regressions were run to examine the individual impact of cash conversion cycle and its components on gross profit. The regression results confirmed previous findings that cash conversion cycle, number of days accounts receivables and inventory were negatively while the number of days accounts payables were positively related to gross profit. All results were statistically significant at 1% level of significance indicating that managers can create profits by keeping current assets and current liabilities to an optimal level. In Pakistan, a little work has been found in finance literature, specifically with reference to shortterm financial management and working capital. However, researchers have discussed the other areas of finance like capital structure, corporate governance, market efficiency, diversification strategy, and investment analysis. In this regard, Mir and Nishat (2004) compared the Pakistani firms’ performance under different corporate governance structures using parameters like ownership structure and identity of owners, board characteristics, financial policy, and control variables like leverages, size and firm risk beta. They measured firm performance through return on asset, Tobin’s q and stock return. Their results showed that firm performance is positively influenced by corporate governance structure variables, while it is adversely affected in case where CEO also heads the Board of Directors. On the same lines, Ghani and Ashraf (2005) examined different business groups and their impact on corporate governance in Pakistan for 582 nonfinancial firms for the period of 1998 to 2002. The results indicated that group firms have higher liquidity, short-term debt repay capacity and lower financial leverage as well as higher sales growth than the non-group firms in each of the study period. Moreover, the returns on assets were higher for group firms but lower Tobin’s q than the non-group firms. 31 In addition, Afza et al. (2006) empirically examined the relationship between the diversification strategy and the performance of sixty-three non-financial firms of Karachi Stock Exchange for a period of three years from 2001-2003. The regression analysis indicated that the best performing firms, if diversify, may reduce their earnings in emerging economy accompanied by increased risk. Therefore, by following the strategy of diversification the market share of firm may increase whereas the profitability may decrease due to higher competition in market. Moreover, Ahmad and Zaman (2001) analyzed the relationship between the uncertainty and returns of firms listed at Karachi Stock Exchange (KSE). Hussain (2001) examined the efficiency of Pakistani equity market, while Irfan and Nishat (2002) applied a case study approach to the key fundamental factors and long run price movements in Karachi Stock Exchange (KSE). However, a related domestic study by Rehman (2006) analyzed the impact of working capital management on 94 Pakistani firms listed in Islamabad stock exchange for a period of 1999-2004. The cash conversion cycle and its components i.e. day accounts receivable, inventory and payable along with current ratio has been used as independent variables while net operating income has been used as profitability measure. The results of correlation and pooled & ordinary least square regression analysis confirmed the negative relationship between working capital measures and net operating income of firms as per the previous studies. Reduction in cash conversion cycle and its components leads to improved firm performance in Pakistan. Finally, Afza and Nazir (2007a) investigated the relationship between the aggressive/conservative working capital policies for seventeen industrial groups and a large sample of 263 public limited companies listed at Karachi Stock Exchange for a period of 1998-2003. Using ANOVA and Least Significant Difference (LSD) test, the study found significant differences among their working capital investment and financing policies across different industries. Moreover, rank order correlation confirmed that these significant differences were remarkably stable over the period of study. The aggressive investment working capital policies were accompanied by aggressive working capital financing policies. Finally, ordinary least regression analysis found a negative relationship between the profitability measures of firms and degree of aggressiveness of working capital investment and financing policies. These results were further confirmed by Afza and Nazir (2007b) on a longer period of time (i.e. 1998-2005) and using market measures of return. Moreover, the later study also took into consideration the impact of aggressiveness of working capital policies on the risk of firm. In conformity with Carpenter and Johnson (1983), the study found no significant relationship between the aggressiveness\conservativeness of working capital policies of firms and their operating and financial risk. 32 Keeping in view the miniature amount of finance literature, particularly in working capital, the present study investigates the relationship of the aggressive and conservative working capital asset management and financing polices and impact on profitability. It further examines whether significant differences exist among the working capital practices of the firms across different industries and whether these aggressive or conservative working capital policies are relatively stable over the period of time. Moreover, the study validates the relationship between working capital asset management and financing policies of a particular firm and examines how a working capital asset management policy corresponds to working capital financing policy. Finally, the impact of aggressive and conservative working capital asset management and financing policies on the risk and profitability of the company has also been explored. In the light of above discussion and literature review, the testable hypotheses formed are: H01 = There is no difference among the working capital investment policies of firms across different industries. Ha1 = There is a difference among the working capital investment policies of firms across different industries. H02 = There is no difference among the working capital financing policies of firms across different industries. Ha2 = There is a difference among the working capital financing policies of firms across different industries. H03 = The working capital policies are not relatively stable over the longer period of time. Ha3 = The working capital policies are relatively stable over the longer period of time. H04 = An aggressive investment working capital policy is not accompanied by a conservative financing policy. Ha4 = An aggressive investment working capital policy is accompanied by a conservative financing policy. H05 = A conservative investment working capital policy is not accompanied by an aggressive financing policy. Ha5 = A conservative investment working capital policy is accompanied by an aggressive financing policy. 33 H06 = An aggressive working capital policy is inversely related to firms’ profitability. Ha6 = An aggressive working capital policy is directly related to firms’ profitability. H07 = An aggressive working capital policy is directly related to firms’ risk. Ha7 = An aggressive working capital policy is inversely related to firms’ risk. The above mentioned hypotheses have been validated using various quantitative data analysis techniques like ANOVA, rank order correlations, regression analysis. ANOVA has been further supported by HSD, LSD and Bonferroni post hoc tests whereas, the regression analysis done is organized in year-wise regression, using mean values and using panel data analysis. The details discussions of these statistical techniques are presented in the following section of methodology. 34 Chapter 3 RESEARCH METHODOLOGY 3.1 Variables of the Study The study used aggressive investment policy and conservative investment policy as measuring variables of working capital management as used by Weinraub and Visscher (1998) who analyzed working capital policies of 126 industrial firms in US market. Aggressive Investment Policy (AIP) results in minimal level of investment in current assets versus fixed assets. In contrast, a conservative investment policy places a greater proportion of capital in liquid assets with the opportunity cost of lesser profitability. As the level of current assets is increased in proportion to the total assets of the firm, the management is being more conservative in managing the current assets of the firm. In order to measure the degree of aggressiveness of Working Capital Assets Management policy, following ratio has been used: AIP = Total Current Assets (TCA) Total Assets (TA) : Where a lower ratio means a relatively aggressive policy. On the other hand, Aggressive Financing Policy (AFP) utilizes higher levels of current liabilities and less long-term debt. In contrast, a conservative financing policy uses more long-term debt and capital and less current liabilities. The firms are more aggressive in terms of current liabilities management if they are concentrating on the use of more current liabilities which put their liquidity on risk. The degree of aggressiveness of a financing policy adopted by a firm will be measured by Working Capital Financing Policy and following ratio has been used: AFP = Total Current Liabilities (TCL) Total Assets (TA) : Where a higher ratio means a relatively aggressive policy. The impact of working capital policies on the profitability has been analyzed through accounting measures of profitability as well as market measures of profitability. In the accounting measures, 35 frequently used Return on Assets (ROA) and Return on Equity (ROE) are applied. These accounting variables of return are calculated as: Return on Assets (ROA) = Return on Equity (ROE) = Net Earnings after Taxes (NEAT) Book Value of Assets (BVA) Net Earnings after Taxes (NEAT) Book Value of Equity (BVE) In the market measures of profitability, Market Return (MKRT) has been taken as the third performance variable in the market measures of profitability. Market Return (MKRT) is calculated by the following equation: Market Return (MKRT) = (Pt - Pt-1 ) + Divt Pt-1 Where: Pt = Price of the stock of a firm at time period t Pt-1 = Price of the stock of a firm at time period t-1 Divt = Dividend paid by a firm at time period t Furthermore, Tobin’s q is used as the fourth market measure of return. Tobin's q compares the value of a company given by financial markets with the value of a company's assets. A low q (between 0 and 1) means that the cost to replace a firm's assets is greater than the value of its stock. This implies that the stock is undervalued. Conversely, a high q (greater than 1) implies that a firm's stock is more expensive than the replacement cost of its assets, which implies that the stock is overvalued. It is calculated as: Tobin’s q = Market Value of Firm (MVF) Book Value of Assets (BVA) Where: : Market Value of Firm (MVF) is the sum of Book Value of long plus short term debt and market value of equity. Market value of equity is calculated by multiplying the number of shares outstanding with the current market price of the stock in a particular year. 36 The last variable in the study is the risk faced by the firms when opting for the aggressive working capital management policies. The risk is measured by the variability in the returns of firms. Standard Deviation (SD) of the all four profitability measures is used as the risk of a particular firm. 3.2 Control Variables In working capital literature, various studies have used the control variables along with the main variables of working capital in order to have a pertinent analysis of working capital management on the profitability of firms (Lamberson 1995; Smith & Begemann 1997; Deelof 2003; Eljelly 2004; Teruel and Solano 2005; Lazaridis and Tryfonidis 2006). On the same lines, along with working capital variables, the present study has taken into consideration some control variables relating to firms like the size of the firm, the growth in its sales, and its financial leverage. The size of the firm (SIZE) has been measured as the logarithm of its total assets as the original value of total assets may perturb the analysis. The growth of firm (GROWTH) is measured by variation in its annual sales value with reference to previous year’s sales [SGROW as (Salest – Salest-1)/Salest-1]. Moreover, the financial leverage (LVRG) has been taken as the debt to equity ratio of each firm for the whole of sample period. Some researchers like Dellof (2003), in his study of large Belgian firms, also considered the ratio of fixed financial assets to total assets as a control variable; however, this variable can not be included in current study because of unavailability of appropriate data as most of firms don’t disclose the full information in the financial statements. Finally, since good economic conditions tend to be reflected in a firm’s profitability (Lamberson 1995), this phenomenon has been controlled for the evolution of the economic cycle using the variable GDPGR, which measures the annual GDP growth in Pakistan for each of the study year of 1998-2005. 3.3 Statistical Analysis One-way ANOVA test has been used to compare the means of working capital assets management and financing polices of various industrial sector and to find out the significant difference among the sectoral working capital policies. The result are further validated by performing Least Significant Difference (LSD) and Bonferroni test on the mean values of TCA/TA ratio and TCL/TA ratio to measure the differences in the aggressive and conservative working capital assets management and financing policies across the industrial groups. Furthermore, Rank Order Correlation has been used to test the relative stability of the policies over the years of study. 37 Next is to examine that how aggressive working capital assets management policy corresponded to aggressive financing policy. This relationship has been tested on yearly basis. For the first year, the industrial sectors are ranked from low CA/TA ratios to high ratios, corresponding to ascending order of relatively aggressive policies. The same procedure has been done for financing policies of firms. Then, Rank order correlations between the two policies are computed for year one. This procedure has been repeated for each of the remaining seven years. The impact of aggressive and conservative working capital policies on the profitability and risk of the firm has been evaluated through applying the regression analysis. The performance variables (ROA, ROE, MRKT, Tobin’s q) as well as the TCA/TA and TCL/TA along with the control variables has been regressed using cross sectional regressions. The following regression equations are run to estimate the impact of working capital policies on the accounting as well as market measures of profitability. The proposed regression models are as follows: ROA it = α + β1 (TCA/TA it) + β2 (SIZE it) + β3 (GROWTH it) + β4 (LVRGit) + β5 (GDPGR it) + ε ………… (1) ROE it = α + β1 (TCA/TA it) + β2 (SIZE it) + β3 (GROWTH it) + β4 (LVRGit) + β5 (GDPGR it) + ε ………… (2) MRKT it = α + β1 (TCA/TA it) + β2 (SIZE it) + β3 (GROWTH it) + β4 (LVRGit) + β5 (GDPGR it) + ε ………… (3) Tobin’s q it = α + β1 (TCA/TA it) + β2 (SIZE it) + β3 (GROWTH it) + β4 (LVRGit) + β5 (GDPGR it) + ε ………… (4) And ROA it = α + β1 (TCL/TA it) + β2 (SIZE it) + β3 (GROWTH it) + β4 (LVRGit) + β5 (GDPGR it) + ε ………… (5) ROE it = α + β1 (TCL/TA it) + β2 (SIZE it) + β3 (GROWTH it) + β4 (LVRGit) + β5 (GDPGR it) + ε ………… (6) 38 MRKT it = α + β1 (TCL/TA it) + β2 (SIZE it) + β3 (GROWTH it) + β4 (LVRGit) + β5 (GDPGR it) + ε ………… (7) Tobin’s q it = α + β1 (TCL/TA it) + β2 (SIZE it) + β3 (GROWTH it) + β4 (LVRGit) + β5 (GDPGR it) + ε ………… (8) Where: ROA it = Return on Assets of Firm i for time period t ROE it = Return on Equity of Firm i for time period t MRKT it = Market Rate of Return of Firm i for time period t Tobin’s q i = Value of q of Firm i for time period t TCA/TA it = Total Current Assets to Total Assets Ratio of Firm i for time period t TCL/TA it = Total Current Liabilities to Total Assets Ratio of Firm i for time period t α = intercept ε = error term of the model The impact of the working capital assets management and financing polices on the relative risk has been measured by applying regression models for the risk of the company and its working capital management policies over the period of 1998-2005. The regression equations are: SDROAi = α + β1 (TCA/TA i) + β2 (SIZE i) + β3 (GROWTH i) + β4 (LVRGi) + β5 (GDPGR i) + ε ………… (9) SDROEi = α + β1 (TCA/TA i) + β2 (SIZE i) + β3 (GROWTH i) + β4 (LVRGi) + β5 (GDPGR i) + ε ………… (10) SDMARKTi = α + β1 (TCA/TA i) + β2 (SIZE i) + β3 (GROWTH i) + β4 (LVRGi) + β5 (GDPGR i) + ε ………… (11) SDqi = α + β1 (TCA/TA i) + β2 (SIZE i) + β3 (GROWTH i) + β4 (LVRGi) + β5 (GDPGR i) + ε ………… (12) SDSalesi = α + β1 (TCA/TA i) + β2 (SIZE i) + β3 (GROWTH i) + β4 (LVRGi) + β5 (GDPGR i) + ε ………… (13) And 39 SDROAi = α + β1 (TCL/TA i) + β2 (SIZE i) + β3 (GROWTH i) + β4 (LVRGi) + β5 (GDPGR i) + ε ………… (14) SDROEi = α + β1 (TCL/TA i) + β2 (SIZE i) + β3 (GROWTH i) + β4 (LVRGi) + β5 (GDPGR t) + ε ………… (15) SDMARKTi = α + β1 (TCL/TA i) + β2 (SIZE i) + β3 (GROWTH i) + β4 (LVRGi) + β5 (GDPGR i) + ε ………… (16) SDqi = α + β1 (TCL/TA i) + β2 (SIZE i) + β3 (GROWTH i) + β4 (LVRGi) + β5 (GDPGR i) + ε ………… (17) SDSalesi = α + β1 (TCL/TA i) + β2 (SIZE i) + β3 (GROWTH i) + β4 (LVRGi) + β5 (GDPGR i) + ε ………… (18) Where: SDi = Standard Deviation representing risk of Firm i 3.4 Sample & Data The total population of the study is all non-financial firms listed at Karachi Stock Exchange. Karachi Stock Exchange (KSE) has divided the non-financial firms into various industrial sectors based on their nature of business. The number of firms in these industrial sectors varies from 6 to 37 with the exception of Textile Composite and Textile Spinning sectors having 62 and 157 firms respectively. In order to be included in the population, a firm must be in business for the whole study period. Neither of the firms should be de-listed by the Karachi Stock Exchange (KSE) nor should it be merged with any other firm during the whole window period. The merged and delisting from the Karachi Stock Exchange, due to any reason/restriction imposed by the regulators, make the firm ineligible to be included in the study. New incumbents in the market during the study period have also not included in the population. Furthermore, firms must have complete data for the period of 1998-2005. Firms with negative equity during the study period have also been removed for the population of study. 40 As a first step, 438 non-financial firms were selected whose financial data was available for the study period i.e. 1998-2005. Furthermore, firms with missing data, negative equity and negative profitability for study period were deleted from the sample leaving us with the final population of 204 non-financial firms from 17 industrial sectors. The whole population has been taken as the sample for analysis of working capital policies. The list of sample companies along with respective industrials sectors has been included in the annexure number 1 at the end of the report. The study has used annual financial data of 204 non-financial firms for the period of 1998-2005. For the data collection purpose, various sources have been utilized. The book value based required financial data of these firms was obtained from the companies’ annual reports and publications of State Bank of Pakistan. The data regarding annual average market prices has been collected from the daily quotations of Karachi Stock Exchange (KSE) and used for analysis by the above mentioned statistical techniques and results are discussed in the coming chapter. 41 Chapter 4 ANALYSIS and DISCUSSIONS 4.1 Descriptive Analysis Table 4.1 presents the descriptive analysis of 204 non-financial public limited firms of Karachi Stock Exchange (KSE) from 1998 to 2003. The study has used nine variables for the analysis purpose including five independent variables and four dependant performance measures. The independent variables are investment policy and financing policy of the firms as a measure of working capital management of the sampled firms. Other three independent control variables used are size as measured by the total assets of the firm, growth of firms as relative change in sales as compared to previous year and leverage of the firms. All the variables are averaged for each firm for all eight years and presented in sixteen sectors as categorized by the Karachi Stock Exchange (KSE). The standard deviation is the variation of these ratios for each year and an average value has been calculated for each industry by the same method. Panel A of Table 4.1 presents the statistics for working capital management of firms and size of firm along with the number of firms in each sector of Pakistani market. The number of firms varies from 3 to 40 firms in each industry accumulating the total sample of the study to 204 non-financial public firms. The smallest sector of present study is leather and tanneries sector having only 3 firms whereas, on the other side, textile spinning sector has 40 firms. On average, we do have a sufficient number of companies in each of the sector. The mean values of TCA/TA ranges from 0.0682 to 0.9265 of cement sector and automobiles sector respectively. Approximately all the sectors are having average of investment policy near to 0.50 except cement and leather sector. Cement sector is found to be more aggressive in managing the current assets where its average TCA/TA ratio is 0.2758. On the other hand, leather and tanneries sector is much conservative to its currents assets management having TCA/TA ratio of 0.8322. The variation in the TCA/TA is less than 0.1 for all the industrial sectors. Remaining sectors are in the middle of those extreme values and are neither too much conservative nor aggressive while managing current assets. 42 TABLE 4.1 (Panel A): Descriptive Statistics for Study Variables Industries Investment Policy N Financing Policy Size (In Million Rupees) Mean SD Min Max Mean SD Min Max Mean SD Min Max Automobiles and Allied 15 0.7059 0.1346 0.3347 0.9265 0.4972 0.0845 0.3762 0.6547 2,314 2,495 150 8,505 Cables and Electric 4 0.7725 0.1657 0.5265 0.8808 0.5778 0.1020 0.4478 0.6957 2,592 2,197 706 4,886 Cement 12 0.2758 0.1884 0.0824 0.7821 0.2624 0.0903 0.1471 0.4235 3,894 3,118 822 10,403 Chemicals and Pharma. 22 0.6598 0.1698 0.2767 0.8869 0.4207 0.1244 0.2202 0.6159 3,804 6,424 103 22,611 Engineering and Allied 7 0.5924 0.1949 0.3032 0.8762 0.4166 0.1511 0.2142 0.5932 1,096 935 86 2,375 Food and Allied 15 0.6030 0.1327 0.3995 0.8304 0.5056 0.1571 0.2769 0.8025 1,237 1,809 161 6,541 Fuel and Energy 17 0.5412 0.2092 0.2364 0.9159 0.4479 0.2142 0.1444 0.8415 14,089 18,055 106 58,696 Glass and Ceramics 4 0.5089 0.1054 0.4050 0.6258 0.3094 0.1214 0.1855 0.4751 582 53 512 630 Leather and Tanneries 3 0.8322 0.0548 0.7956 0.8953 0.6871 0.1081 0.5991 0.8077 1,175 755 357 1,845 Paper and Board 7 0.5977 0.2057 0.3476 0.8667 0.3139 0.1056 0.1457 0.5033 1,680 2,344 69 6,832 Sugar 18 0.4218 0.0974 0.2735 0.5789 0.4306 0.1052 0.1937 0.6152 988 427 431 1,708 Synthetic & Rayon 9 0.4409 0.1862 0.1506 0.7466 0.3655 0.1549 0.1720 0.6454 4,280 5,604 130 16,221 Tex.

The most aggressive sector in current liabilities management is leather sector having approximately 70% of its financing generated from short term sources of funds. Whereas, the cement sector in very much conservative in short term liabilities management and generate only 26% funds from short term payables. However, the variation in financing policies is relatively lesser over the eight years of study as compared to investment policies with almost half of the industries having standard deviation less than 0.1. Size of the firms is given in the third main column of Panel A of Table 4.1. Size is also averaged for eight years of study i.e. 1998-2005. The smallest sector is glass and ceramics sector which has maximum of 630 millions rupees of total assets with an average size of firms in the sector of 582 million rupees. Other small sectors includes textile weaving and sugar sectors which have, on average, total assets worth of less than 1000 million rupees. The larger sectors include fuel and energy and transportation sectors. In fuel and energy, we do have some large refineries whereas Pakistan International Airlines and Pakistan Telecommunication Company make the transportation sectors the larger with more total assets. Panel B of Table 4.1 represents descriptive statistics for growth of firms, leverage and return on assets for 204 sampled firms. Cables and Electric sector is one having maximum growth opportunities with more than 100% growth in sales. Whereas leather, paper & board, cement and chemicals & pharmaceutical sectors are sectors with the minimum growth rates of 6.39%, 7.23%, 8.87% and 9.85% respectively. The larger firms with more total assets like energy sector and transportation sectors do have average growth rates of a slighter more than 10%. Our data support the traditional notion that smaller firms usually have more growth opportunities. It is evident from the descriptive statistics that relatively smaller firms of cables and electric sector and engineering sector have maximum growth rates among whole of the sample firms. It is further noticed that firms with more growth opportunities also have higher leverage ratio during whole of the window period. The greatest leverage ratio is for the cables sector i.e. 17.08 whereas engineering sector also has third highest leverage ration among all sixteen non-financial public limited firms. It may be argued that firms with higher growth opportunities used to cater their financing needs from the external sources of funds most of the times which is a quick way to raise funds. These firms can fulfill their financing needs either by short term fund raising or by issuing long term debt securities 46 instead of being involved in complicated and procedures of equity offering. One more argument in this regard may be that due to agency problem, managers of high growth firms issue debt to fully capitalize on the future profits expected from the higher sales in coming years for their own individual benefits. Table 4.1 also depicts some information regarding performance of 204 sampled industrial firms of the study. These performance measures include two accounting measures of returns based on book value data whereas two other measures are being calculated from the market data for the period of 19982005. The average return on assets for non-financial firms in Pakistan is 5.66%. There are only six sectors which are yielding more than this benchmark. The highest performing sector on the basis of ROA is paper and board with ROA of 10.28% followed by glass and ceramics with ROA of 8.73%. The engineering and cables & electric sectors are among the lowest returns generating sectors which were supposed to be the sectors with the maximum growth opportunities. However, the smaller firms are still able to earn more profits as compared to larger firms i.e. glass and ceramics; the smallest sector of the sample. The ROA is also not subject to major variations as the standard deviation of returns is relatively lower for almost all the sectors. These yielding performances are more or less same for the second book-based performance variable Return on Equity (ROE). 57However, the situation is a little bit different when we talk about the market-based return measures i.e. Market Rate of Returns (MRR) and Tobin’s q which are reported in Panel C of Table 4.1. Engineering sectors which was not performing on book valued measure of returns of ROA and ROE became the highest earning sector in the market. The investors are giving more value to sectors which are having more growth opportunities i.e. engineering, cables, textile composite sectors which also depicts the speculative behavior of the Pakistani investors. However, there is also a sector which is performing at the lowest among all the sectors i.e. Leather and tanneries having only 18.84% growth in market share price as compared to the previous years. Tobin’s q is a performance measure which is being used by researchers studying the stock markets behaviors. The use of this measure is extended in recent years as a measure comparative to traditional performance variables. The q is a comparative measure of market value of firms in relation to book value of firm. A value of q greater than one indicates the strength of the firm in the market. The average q of our sample is calculated as 1.13 which means that market value of firms in Pakistani market, on average, is greater than their respective book value. However, there are various industrial sectors in Pakistan having q value less than one; in our sample half of total sample. The highest 47 performing sector on the basis of Tobin’s q is food and allied sector where investors are believing that its value should be more than double of its book value. It is also the sector with the greatest variation in performance where once it has produced a q value of 11.92 even. 4.2 Analysis of Variance (ANOVA) Difference in the relative degree of aggressive/conservative investment policies across industries has been testes through one-way ANOVA and results are presented in Table 4.2. The resulting value of Ftest is 7.639 which is significant at 1% level indicates that a significant difference exists between the industry practices relating to aggressive/conservative investment policies. To further examine the strength of results of ANOVA, some post hoc tests has also been applied like Least Significant Difference (LSD), Tukey’s HSD and Bonferroni test to compare the industry mean values of TCA/TA on a paired sample basis. Tukey’s HSD test has also been used by Weinraub and Visscher (1998) to examine differences in working capital policies. The results are presented in Panel A, B, C of Table 4.2 respectively. For Least Significant Difference (LSD), among 120 pairs, 69 pairs are statistically significant at difference levels of significance [Panel A]. These results are further supported by Tukey’s HSD and Bonferroni test in Panel B and C of Table 4.2 respectively. It is apparent from both ANOVA and all three post hoc tests for variance that significant differences exist among the various industrial groups regarding investment working capital management policies. The different firms in different industrial group might have different policy regarding maintenance of its working capital investment policy. ANOVA and the three post hoc tests have also been applied to TCL/TA ratio to examine the differences in financing policies among industries over the study period. The results are presented in Table 4.3 [Panel A, B, C]. The significant F-statistics clearly indicates the existence of statistically significant differences among industries regarding financing working capital policies. Panel A (Least Significant Difference Test) of Table 4.3 also shows 66 pairs of industries that are significant at different level of significant. It is clear now that significant industry differences do exist in the relative degree of both aggressive/conservative working capital investment and financing policies. However, both the ANOVA and three post hoc tests, including Test of Least Significance Difference (LSD), Tukey’s HSD and Bonferroni Test, show these differences are generally broader and more significant when examining working capital investment policies. In the light of results presented in Table 4.2 and 4.3, we can accept our first two hypotheses i.e. H1 and H2, which state the significant differences among the working capital management practices across different industries. 48 TABLE 4.2 (Panel A) Results of ANOVA (F-test) and Test of Least Significant Differences (LSD) for Total Current Assets / Total Assets (TCA / TA) F Statistics = 7.639*** Industries Auto Cabl. & Elec.

For this purpose, a mean industry value for TCA/TA has been calculated for each industry for each year and ranked from the highest to lowest ratio. Then the base year (1998) rankings were sequentially compared to the TCA/TA rankings of each succeeding year. The industries were also ranked for each year on the basis of Total Current Liabilities / Total Assets and their rankings were also compared with the base year of 1998. The rank order correlation coefficients and their respective Z-values are presented in Table 4.4. The correlation between the base year and each of the succeeding year is high as well as highly statistically significant for both of the working capital management policies i.e. working capital investment policy and working capital financing policy. TABLE 4.4 Rank Order Correlations for Working Capital Management Policies TCA / TA TCL / TA Between Base Year and: Year Correlation Z Value Correlation Z Value Year 2 0.953 3.690*** 0.959 3.713*** Year 3 0.876 3.395*** 0.800 3.098*** Year 4 0.891 3.452*** 0.868 3.360*** Year 5 0.874 3.383*** 0.859 3.326*** Year 6 0.859 3.326*** 0.829 3.213*** Year 7 0.944 3.656*** 0.909 3.519*** Year 8 0.941 3.645*** 0.859 3.326*** *** Significant at 1 % level It is evident from the results that each industry maintained its relative degree of aggressiveness for both working capital investment (TCA/TA) and financing (TCL/TA) policies over time. There is strong correlation between the base year rankings and succeeding year rankings for both the policies. Furthermore, these correlation values are statistically significant at 1% level. This means not only 55 significance differences among working capital management policies exist but also they persist over the longer period of time. Therefore, we can accept our third hypotheses H3 that working capital policies are relatively stable over time. Moreover, the relationship between the working capital investment and financing policies is also examined in this study. The objective was to determine how an aggressive investment policy corresponds to aggressive financing policy. To validate this relationship, a year-by-year analysis has been conducted. Industries are ranked from low to high TCA/TA ratios for the first year, an ascending order of degree of aggressiveness for working capital investment policy. Sample industries are also ranked from high to low TCL/TA ratios corresponding to an ascending order of aggressiveness of working capital financing polices. Rank order correlation has been performed on these policies for first year and all succeeding years subsequently. TABLE 4.5 Year-wise Rank Correlation of Working Capital Management Policies Year Correlation Z Value 1998 -0.697 2.700** 1999 -0.791 3.064*** 2000 -0.665 2.574** 2001 -0.579 2.244** 2002 -0.591 2.290** 2003 -0.497 1.925** 2004 -0.671 2.597** 2005 -0.682 2.643** *** Significant at 1 % level ** Significant at 5 % level * Significant at 10 % level The results are presented in Table 4.5. All the coefficients of rank order correlation are positive and statistically significant at 5% except year 1999, which is significant at 1% level of significance. The negative correlation between the investment and financing policies indicate the industries, which follow aggressive investment working capital policies, those simultaneously follow conservative working capital financing policies to balance the aggressive impact of investment policies. Same is the case where once a conservative investment policy to working capital management is adopted, that is 56 compensated by having an aggressive approach to working capital asset management. Therefore, H4 and H5 are also accepted which states that an aggressive investment policy is accompanied by an aggressive financing policy on the other hand and vice versa. 4.4 Regression Analysis Finally, impact of aggressive/conservative working capital management policies on profitability of firms has been examined by estimating linear regression models # 1-8. The mean TCA/TA values of each firm along with the control variables for eight years has been regressed against mean values of performance variables i.e. ROA, ROE, MRR, Tobin’s q in individual regression models. The combined results are presented in Panel A of Table 4.6. Table 4.6 [Panel A] reports the result of regression model in which the impact of working capital investment policy on four performance measurements has been examined. The F-values of regression models are found statistically significant whereas Durbin-Watson statistics of more than 1.7 indicating less correlation between the independent variables of all the four regressions models. The t-statistics of working capital investment policy is positive and statistically significant at 1%level for Return on Assets and Tobin’s q. However, Return on Equity and Market Rate of Returns is not found to be statistically correlated with the working capital investment management of firms. The positive coefficient of TCA/TA indicates a negative relationship between the degree of aggressiveness of investment policy and return on assets. As the TCA/TA increases, degree of aggressiveness decreases, and return on assets increases. Therefore, there is negative relationship between the relative degree of aggressiveness of working capital investment policies of firms and both performance measures i.e. ROA and Tobin’s q. This similarity in market and accounting returns confirms the notion that investors do not believe in the aggressive approach of working capital management, hence, they don’t give any additional value to the firms in Karachi Stock Exchange. The control variables used in the regression models are natural log of average size, average sales growth and average leverage. All the control variables have their impact on the performance of the firms; however, their impact is limited to performance variables based on the book values i.e. return on assets and return on equity. Firm’s growth and size cause the returns of the firms to be increased and it is statistically significant. This phenomenon confirms the notion that leverage, growth and size are strongly correlated with the book value based performance measures (Deloof 2003; Eljelly 2004). 57 Table 4.6 (Panel A) Regression Analysis of Average Performance Measures & Working Capital Investment Policy A(TCA/TA) ASIZE AGROWTH ALVRG Year F-Value D-W R2 β t-value β t-value β t-value β t-value AROA .215 3.316*** .171 2.621*** .271 3.039*** -.428 -4.814*** 9.894*** 1.967 .166 AROE .029 1.081 .055 2.035** -.432 -11.74*** -.576 -15.67*** 299.31*** 1.686 .857 AMRR -.089 -1.282 .015 .217 .063 .654 .119 1.249 1.947* 1.987 .038 A Tobin’s q .190 2.735*** .125 1.798* .009 .090 .001 .005 2.522** 1.936 .048 *** Significant at 1% Level ** Significant at 5% Level * Significant at 10% Level A (TCA / TA) = Average Working Capital Investment Policy for the period of 1998-2005 ASIZE = Average Size of firms measured by the natural log of total assets for the period of 1998-2005 AGRWOTH = Average Sales Growth of firms for the period of 1998-2005 ALVRG = Firms’ Average leverage level for the period of 1998-2005 58 Table 4.6 (Panel B) Regression Analysis of Average Performance Measures & Working Capital Financing Policy A(TCL/TA) Year ASIZE AGROWTH ALVRG F-Value D-W R2 β t-value β t-value β t-value β t-value ROA -.197 -.2878*** .141 2.151** .201 2.175** -.344 -3.672*** 9.124*** 1.742 .155 ROE .094 3.446*** .059 2.265** -.403 -10.91*** -.614 -16.37*** 317.98*** 1.733 .865 MRR -.112 -1.537 .014 .195 .029 .298 .164 1.644* 2.132* 1.971 .041 Tobin’s q .171 2.334** .123 1.766* .057 .583 -.067 -.673 2.008* 1.879 .039 *** Significant at 1% Level ** Significant at 5% Level * Significant at 10% Level A (TCL / TA) = Average Working Capital Financing Policy for the period of 1998-2005 ASIZE = Average Size of firms measured by the natural log of total assets for the period of 1998-2005 AGRWOTH = Average Sales Growth of firms for the period of 1998-2005 ALVRG = Firms’ Average leverage level for the period of 1998-2005 59 Panel B of Table 4.6 reports regression results for working capital financing policy and the four performance measures. The F-value of all four regression models and Durbin-Watson statistics indicating same results as we have in Panel A. The relationship between the control variables and performance measures is also same as discussed earlier. The negative value of β coefficient for TCL/TA also points out the same negative relationship between the aggressiveness of working capital financing policy and return on assets. Higher the TCL/TA ratio, more aggressive the financing policy, that yields negative return on assets. However, the relationship between working capital financing policy and return on equity is found to be positive and statistically significant. Moreover, the firms are aggressive in terms of working capital financing policy, higher the TCL/TA ratio, yet higher the return on equity. This has an obvious reason; when firms are more aggressive towards managing finances of short term, they use more current liabilities as a percentage of total assets. Hence, they are using less long term debt and shareholders equity, which ultimately increases the return on equity. But, surprisingly, the relationship between Tobin’s q and working capital financing policy has been established as positive and statistically significant. Investors in the stock exchange are giving more value to the firms which are adopting an aggressive approach towards working capital financing policy so these firms are producing higher q value. To have a more lucid insight into the relationships established, the year analysis has also been conducted by running cross-sectional regressions for each of the year from 1998-2005 for both working capital investment and financing policy. For each year, independent variables have been regressed against performance measures and results are reported in Table 4.7 to 4.10 indicating the impact of working capital policies on the profitability of firms in Pakistan. The model F-values and the DurbinWatson statistics indicate overall best fit of the model. Table 4.7 [Panel A] indicate regression analysis of return on assets and working capital investment policy for each of eight years of study from 1998-2005. The positive and significant β values confirms our previous results that there is a negative correlation between the degree of aggressiveness of working capital investment policy and return on assets. There are two years i.e. 1998 and 2004, for which results are not statistically significant; however, the relationship was same as found earlier. Panel B also confirms the same negative correlation between the working capital financing policy and return on assets. Table 4.8 takes into consideration year-wise regression analysis of working capital policies and return on equity. Panel A & B also confirms the findings of Table 4.6 [Panel B] that there is 60 positive and significant correlation between working capital policies and return on equity. However, results are broader for return on assets as compared to return on equity from the statistical significance point of view. Though, the results are statistically less impressive for ROE, which is apparent from the low level of significance of β coefficients and t-values, however, we can predict a positive relationship between the degree of aggressiveness of working capital policies and return on equity. Table 4.9 and 4.10 provide investigation into the relationship of working capital policies and two market value based firm’s performance measures. Results of regression analysis of market rate of return and working capital investment and financing policy are reported in Panel A & B of Table 4.9 respectively. Supporting the earlier findings, market rate of returns failed to relate with either working capital investment policy or working capital financing policy. The only exception was the year 2004 where the β’s were found to be negatively and significantly correlated with working capital variables; however, the results based on market rate of returns can not be generalized for whole of the sample period. Lastly, Table 4.10 shows the year-wise regression analysis of Tobin’s q; another market value based performance variable; and working capital policies of firms for the period of 1998-2005. Yet again the results are in accordance with our earlier findings and pose a negative relationship between aggressiveness of working capital investment policy and q as well as a positive relationship between degree of aggressiveness of working capital financing policy and Tobin’s q. As the level of current assets and current liabilities in the balance sheet of a firm increases, the short term repaying capacity of firms increase, investors perceive the firm a better performer; hence they give more value to the firm which leads the q value of firm greater than one. To further validate the above-mentioned results, the impact of working capital investment and working capital financing policy on performance variables has also been examined on large set of data. For this purpose, panel data regression analysis has been used. The panel data set has been developed for eight years of study and 204 sampled firms which produced 1632 year end observations. In the panel data regression, to control the economic influence on performance of firms, real GDP growth rate (GDPGR) has also been included as a control variable. According to the results reported in Table 4.11, model Fvalues are found statistically significant and Durbin-Watson indicates less autocorrelation between the independent variables. The results are again confirming our previous results and report a significant 61 Table 4.7 (Panel A) Year-wise Regression Analysis of Return on Assets (ROA) & Working Capital Investment Policy TCA/TA Year SIZE GROWTH LVRG F-Value D-W R2 -1.144 1.153 1.909 .023 -.276 -4.599*** 19.245*** 1.986 .281 .573 -.326 -4.898 9.238*** 1.857 .157 .099 1.444 -.008 -.118 3.914*** 1.941 .073 1.561 .277 4.268*** -.253 -3.874*** 11.775*** 2.094 .191 .221 3.463*** .129 2.013** -.168 -2.619*** 11.924*** 1.811 .193 .308 .100 1.427 -.002 -.026 -.117 -1.65* 1.240 1.918 .024 4.999*** .243 3.763*** .048 .754 -.195 -3.035*** 11.785*** 1.806 .192 β t-value β t-value β t-value β t-value 1998 .043 .615 .098 1.395 .057 .414 -.157 1999 .201 3.319*** -.063 -1.046 .409 6.79*** 2000 .240 3.658*** -.057 -.857 .038 2001 .250 3.661*** .045 .651 2002 .149 2.322** .101 2003 .319 5.007*** 2004 .022 2005 .321 *** Significant at 1% Level ** Significant at 5% Level * Significant at 10% Level TCA / TA = Working Capital Investment Policy SIZE = Size of firms measured by the natural log of total assets GRWOTH = Sales Growth of firms LVRG = Firms’ leverage level 62 Table 4.7 (Panel B) Year-wise Regression Analysis of Return on Assets (ROA) & Working Capital Financing Policy TCL/TA Year SIZE GROWTH LVRG F-Value D-W R2 -.932 2.019* 1.887 .039 -.235 -3.642*** 17.306*** 1.889 .258 .588 -.278 -3.669*** 5.649*** 1.822 .102 .096 1.382 .002 .003 1.574 1.854 .031 1.181 .287 4.453*** -.184 -2.661*** 12.176*** 1.955 .197 .192 2.909*** .148 2.225** -.129 -1.906* 7.968*** 1.544 .138 -2.502*** .093 1.353 .026 .370 -.088 -1.256 2.818** 1.914 .054 -3.858*** .210 3.196*** .084 1.283 -.116 -1.709* 9.011*** 1.731 .153 β t-value β t-value β t-value β t-value 1998 -.136 -1.942 .087 1.241 .030 .219 -.127 1999 -.138 -2.140** -.089 -1.452 .392 6.416*** 2000 -.050 -.675 -.075 -1.097 .040 2001 -.142 -2.035** .020 .288 2002 -.176 -2.593** .077 2003 -.221 -3.270*** 2004 -.178 2005 -.261 *** Significant at 1% Level ** Significant at 5% Level * Significant at 10% Level TCL / TA = Working Capital Financing Policy SIZE = Size of firms measured by the natural log of total assets GRWOTH = Sales Growth of firms LVRG = Firms’ leverage level 63 Table 4.8 (Panel A) Year-wise Regression Analysis of Return on Equity (ROE) & Working Capital Investment Policy TCA/TA Year SIZE GROWTH LVRG F-Value D-W R2 -6.732*** 27.456*** 1.984 .356 -.186 -3.029*** 16.235*** 1.981 .246 .558 -.467 -7.450*** 16.616*** 1.591 .251 .102 1.545 -.264 -3.963*** 7.094*** 2.010 .125 1.83* .210 3.246*** -.307 -4.707*** 11.906*** 2.414 .193 .253 3.93*** .065 1.001 -.214 -3.312*** 10.961*** 1.777 .181 -.099 .102 1.439 -.030 -.426 -.033 .461 0.627 1.933 .012 4.072*** .244 4.012*** .098 1.620* -.385 -6.346*** 19.135*** 1.960 .278 β t-value β t-value β t-value β t-value 1998 .233 4.070*** .183 3.199*** .266 2.384** -.749 1999 .191 3.092*** -.019 -.306 .428 6.932*** 2000 .234 3.788*** -.009 -.142 .035 2001 .225 3.387*** .052 .782 2002 .172 2.683*** .119 2003 .265 4.125*** 2004 -.007 2005 .248 *** Significant at 1% Level ** Significant at 5% Level * Significant at 10% Level TCA / TA = Working Capital Investment Policy SIZE = Size of firms measured by the natural log of total assets GRWOTH = Sales Growth of firms LVRG = Firms’ leverage level 64 Table 4.8 (Panel B) Year-wise Regression Analysis of Return on Equity (ROE) & Working Capital Financing Policy TCL/TA Year SIZE GROWTH LVRG F-Value D-W R2 -6.172*** 22.239*** 1.896 .309 -.189 -2.846*** 13.211*** 1.974 .210 .622 -.526 -7.485*** 14.535*** 1.603 .226 .102 1.496 -.254 -3.719*** 4.290*** 1.946 .079 1.917** .229 3.555*** -.369 -5.340*** 12.344*** 2.383 .199 .239 3.558*** .077 1.142 -.215 -3.123*** 6.237*** 1.653 .111 -.727 .101 1.435 -.023 -.328 .043 .605 .759 1.936 .015 -.330 .219 3.468*** .117 1.859* -.372 -5.691*** 13.871 1.887 .218 β t-value β t-value β t-value β t-value 1998 -.084 -1.413 .160 2.704*** .242 2.087** -.714 1999 .003 .048 -.033 -.529 .415 6.587*** 2000 .192 2.768*** -.010 -.161 .039 2001 .071 1.044 .046 .668 2002 .200 2.943*** .124 2003 -.031 -.454 2004 -.053 2005 -.021 *** Significant at 1% Level ** Significant at 5% Level * Significant at 10% Level TCL / TA = Working Capital Financing Policy SIZE = Size of firms measured by the natural log of total assets GRWOTH = Sales Growth of firms LVRG = Firms’ leverage level 65 Table 4.9 (Panel A) Year-wise Regression Analysis of Market Rate of Returns (MRR) & Working Capital Investment Policy TCA/TA Year SIZE GROWTH LVRG F-Value D-W R2 -

A significant positive relationship is also found for return on equity and Tobin’s q. Real GDP growth may not be affecting the returns based on book values; however, investors working in the economy may react positively to a positive change in the level of economic activity which is in accordance with the findings of Lamberson (1995). On the other hand, as per our expectations, working capital financing policy indicating a significant negative relationship with return on assets and a significant positive relationship with Tobin’s q. On the basis of the regression analysis, we can partially accept our hypothesis H6, that an aggressive working capital policy is inversely related with firm’s profitability. Managers cannot create value if they are adopting for an aggressive approach towards working capital investment and working capital financing policy. However, if firms are having aggressive approach to manage the short term liabilities, investors give more value to those firms in stock markets. Finally, to empirically test the theory of Belt (1979) and Van-Horne and Wachowicz (2004), impact of working capital policies on risk of the firm have been investigated by regressing the ordinary least square regressions for equations 9-18. The risk is measured by the standard deviation of sales and four return measures as operating and financial risk respectively. The standard deviation has been estimated over the eight years from 1998 to 2005 and then eight regressions have been run for working capital investment and working capital financing policy respectively and result are reported in Table 4.12. The positive β coefficients of σSales, σROA, σROE and σTobin’s q indicate negative relationship between the risk measurements and the degree of aggressiveness of working capital investment policy. On the other hand, mixed results have been found for the working capital financing policy. The increased variation in sales and profitability is attributed to increasing the level of current assets and decreasing the level of current liabilities in the firm. However, these results are not statistically significant except the σSales in case of working capital investment policy and for σSales and σTobin’s q for working capital financing policy. In general, we are unable to establish any statistically significant relationship between the level of current assets and current liabilities and financial risk of Pakistani firms. However, positive significant results for σSales and working capital policies pose a clear picture that increased level of current assets would be having a strong positive impact on the operating risk of the firm i.e. variations in annual sales of the firms. 72 Table 4.12 (Panel A) Regression Analysis of Risk & Working Capital Investment Policy A(TCA/TA) Year ASIZE AGROWTH ALVRG F-Value D-W R2 β t-value β t-value β t-value β t-value σRΟΑ .059 .843 -.165 -2.353** .049 .515 -.044 -.464 1.699 2.016 .033 σROE .014 .588 -.026 -1.063 .449 13.589*** .576 17.432*** 382.43*** 1.849 .885 σMRR -.023 -.321 -.047 -.669 -.018 -.186 .140 1.447 .935 1.828 .018 σTobin's q .137 1.956 .053 .757 .118 1.224 -.042 -.435 1.499 1.955 .029 σSales .170 2.935*** .564 9.712*** .030 .372 -.023 -.290 25.028*** 1.782 .335 *** Significant at 1% Level ** Significant at 5% Level * Significant at 10% Level A (TCA / TA) = Average Working Investment Financing Policy for the period of 1998-2005 ASIZE = Average Size of firms measured by the natural log of total assets for the period of 1998-2005 AGRWOTH = Average Sales Growth of firms for the period of 1998-2005 ALVRG = Firms’ Average leverage level for the period of 1998-2005 73 Table 4.12 (Panel B) Regression Analysis of Risk & Working Capital Financing Policy A(TCL/TA) Year ASIZE AGROWTH ALVRG F-Value D-W R2 β t-value β t-value β t-value β t-value σRΟΑ -.073 -.995 -.174 -2.49*** .024 .245 -.014 -.138 1.770 2.056 .034 σROE -.059 -2.378** -.031 -1.298 .430 12.796*** .600 17.569 393.44*** 1.926 .888 σMRR .107 1.462 -.038 -.539 .017 .174 .095 .947 1.453 1.839 .028 σTobin's q .037 .504 .046 .647 .125 1.256 -.055 -.546 .597 1.955 .012 σSales .225 3.749*** .568 9.902*** .096 1.194 -.113 -1.380 26.989*** 1.796 .352 *** Significant at 1% Level ** Significant at 5% Level * Significant at 10% Level A (TCL / TA) = Average Working Capital Financing Policy for the period of 1998-2005 ASIZE = Average Size of firms measured by the natural log of total assets for the period of 1998-2005 AGRWOTH = Average Sales Growth of firms for the period of 1998-2005 ALVRG = Firms’ Average leverage level for the period of 1998-2005 74 The above results are contradictory with Gardner et al. (1986), Deloof (2003), Eljelly (2004), Teruel & Solano (2005) as well as in accordance with Afza and Nazir (2007a, b) and produced negative relationship between the aggressiveness of working capital policies and accounting measures of profitability. Although, results of all return variables are significant, however, accounting returns measures produced broader and consistent results as compared to market rates of returns. Market returns (MRR) are slightly less significant in our study which is attributed to the more volatile stock market of Pakistan. The Karachi Stock Market is said to be heavily overvalued stock market, and hence, the results based on market share price data are more inconsistent. The degree of aggressiveness of working capital policies is worthwhile only for creating shareholders’ wealth through increasing market performance whereas accounting performance cannot be increased by being aggressive in managing of working capital. Moreover, results of Table 4.12 confirmed the results of Carpenter and Johnson (1983) that there is no statistically significant relationship between the working capital levels and the financial risk of the firms. However, we found some evidence that working capital policies may affect the sales volatility of firms during the study period. Our results are somewhat different from those studies conducted in the developed economies. The Pakistan is one of the emerging economies and Pakistani markets are much transparent and efficient to fully absorb the impact of information. The mixed results found in Market Rate of Return (MRR) are the clear example of this state of Pakistani markets. 75 Chapter 5 CONCLUSION and IMPLICATIONS Working capital practices are used very often in corporate finance yet its implications are normally misunderstood. Even among the professional managers, the controversy and confusion persist. While an accountant will regard working capital as current assets minus current liabilities and call it as net working capital, a finance manager will consider gross current assets as the working capital. Both may be true, but their concerns differ. The former’s concern is arithmetical accuracy as he has to tally the two sides of the balance sheet. But the finance manager’s concern is to find fund for each item of current assets at such costs and risks that the evolving financial structure remains balanced between the two. Working capital management is a very important component of financial management because it directly affects the liquidity and profitability of the company. The managers may adopt the optimal level of working capital that may maximize the firm’s value. Huge inventory levels and a relaxed trade credit policy may lead to high sales. Larger inventory reduce the risk of the stock-out trade credit may stimulate sales because it allows customers to assess product quality before paying (Long et al. 1993). Due to significant cost advantages for suppliers over financial institutions, it can also be an inexpensive source of credit for customer (Peterson and Rajan, 1997). On the other side, granting trade credit and keeping inventories is that money locked up in working capital. The corporate finance literature has traditionally focused on the study of long-term financial decisions. Researchers have particularly examined investments, capital structure, dividends or company valuation decisions, among other topics. However, short-term assets and liabilities are important components of total assets and needs to be carefully analyzed. Management of these short-term assets and liabilities necessitates a careful investigation since the working capital management plays an important role for the firm’s profitability and risk as well as its value (Smith, 1980). Working capital management policies have been divided into two categories by Weinraub and Visscher (1998). A firm may adopt an aggressive working capital asset management policy with a low level of current assets as percentage of total assets. On the other hand, aggressive working capital financing policy uses high level of current liabilities as percentage of total liabilities. Excessive levels of current assets may have a negative effect on the firm’s profitability whereas a low level of current assets may lead to lower level of liquidity and stockouts resulting in difficulties in maintaining smooth operations 76 (Van Horne and Wachowicz 2004). Moreover, aggressive working capital financing policies that utilize higher levels of normally lower cost short-term debt increase the risk of a short-term liquidity problem. Therefore, more aggressive working capital policies are associated with higher return and higher risk while conservative working capital policies are concerned with the lower risk and return (Carpenter and Johnson 1983, Gardner, Mills and Pope 1986, Weinraub and Visscher 1998). The present study investigates the relationship of the aggressive and conservative working capital asset management and financing polices and its impact on profitability of 204 Pakistani firms divided into sixteen industrial groups by Karachi Stock Exchange for a period of 1998-2005. This research examines whether significant differences exist among the working capital practices of the firms across different industries and confirm whether these aggressive or conservative working capital policies are relatively stable over the period of time. It also validates the relationship between working capital asset management and financing policies firms and investigates how a working capital asset management policy corresponds to working capital financing policy. Moreover, the impact of aggressive and conservative working capital asset management and financing policies profitability of the company by using various profitability measures based on accounting data and market values. Finally, to confirm the findings if Carpenter and Johnson (1983), the study has investigated the impact of working capital policies on the financial and operating risk of firms operating in Pakistan. In accordance with Weinraub and Visscher (1998), the study found significant differences among their working capital investment and financing policies across different industries. The nature and adoption of both the working capital policies vary from industry to industry. Some industries are more aggressive towards managing their current assets and liabilities whereas there are some industries being very much conservative in their approach. Moreover, these significant differences are remarkably stable over the period of eight years of time i.e. 1998-2005. The firms tend to maintain their policies over the years and there is less probability of being unhinged in working capital management policies. The positive and significant correlation between the investment and financing policies for industries indicate that industries which pursue aggressive investment working capital policies also follow aggressive working capital financing policies. This is contradicting with the findings of Weinraub and Visscher (1998) that shown a negative correlation between the asset management policies and financing policies. 77 The impact of aggressive/conservative working capital investment and financing policies has been examined through ordinary least square regression models between working capital policies and profitability as well as risk of the firms. For further confirmation, year wise regressions and panel data regression has also been employed. We found a negative relationship between the profitability measures of firms and degree of aggressiveness of working capital investment and financing policies. The firms yield negative returns if they follow an aggressive working capital policy. These results are further validated by examining the impact of aggressive working capital policies on market measures of profitability which was not tested before. The results of Tobin’s q were in line of the accounting measures of profitability and produced almost the same results for working capital investment policy. However, investors in the stock markets are giving more value to the firms through q if they are more aggressive in managing their current liabilities. Moreover, we also confirmed the findings of Carpenter and Johnson (1983) that there is no significant relationship between the aggressiveness or conservativeness of working capital policies of firms and their operating and financial risk. As we used a new measure of profitability i.e. Tobin’s q to estimate the relationship of working capital management and firm returns in Pakistan, the present study is expected to be a significant contribution in finance literature. Moreover, theoretical discussion on risk and working capital management has also been tested on empirical basis in an emerging market of Pakistan. Although the results of present study are in contradiction to some earlier studies on the issue, yet, this phenomenon may be attributed to the inconsistent and volatile economic conditions of Pakistan. The reasons for this contradiction may further be explored in upcoming researches and this topic is left for future. The study also suggests some policy implications for the managers and prospective investor in the emerging market of Pakistan. Firms with the more aggressive policy towards working capital may not be able to generate more profitability. So, as far as the book value performance is concerned, managers can not yield more return on assets and return on equity by following aggressive approach towards short term assets and liabilities. On the other hand, investors are giving more value to the aggressiveness of firms towards working capital financing policies. Firms those are using high level of current liabilities in their financing; their market value is more than the book value. The investors believe that firms using less equity and less ere mounts of long term loans would be performing better than the others. However, there are many other factors like agency problem may play a pivotal role in such firm, and so these factors may further be explored in future. 78 REFERENCES 1.
