Financial Flexibility, Leverage, and Firm Size Abstract We find that small firms have lower leverage ratios, not because of internally generated funds or additional debt financing (as implied by the pecking order theory) but because of additional equity financing (consistent with our financial flexibility hypothesis). This finding can be explained by neither of the pecking order theory and the tradeoff theory—the pecking order may be reversed for small firms that prefer external equity to debt financing while the tradeoff theory may miss out some important aspects of capital structure decisions. We argue that small firms maintain low leverage by issuing equity and building up cash holdings for financial flexibility. Debt covenant often carry restrictions on financing and investment decisions that are especially cumbersome for small, growing firms. Equity financing allows small firms to raise cash without impeding financial flexibility. Consistent with this argument, we find small firms build up cash holdings in order to preserve financial flexibility through external equity. Once we account for financial flexibility, the positive relationship between firm size and leverage found in previous studies is unclear. JEL Classification: G32 Keywords: Financial Flexibility; Trade-off theory; Pecking-order theory I. Introduction Empirical studies in the capital structure find a positive relationship between firm size and leverage.1 Suggested explanations in the literature include: large firms tend to have more leverage perhaps because they are more transparent; have lower asset volatility; more diversified; naturally sell large enough debt issues so that the fixed costs of public borrowing are not prohibitive; have lower probability of default and less financial distress costs. On the other hand, small firms incur higher costs of issuing debt or equity since they are subject to severe asymmetric information problems and default risk, more likely to be growing firms with volatile cash flows and hence have less access to external funds than do large firms. Further, the costs of financial distress are likely to be particularly severe for small firms because much of their value comes from growth options whose value depreciates rapidly if the firm experiences financial distress. In addition, small firms have a large fraction of their assets that are firm specific or intangible, limiting their value as collateral. Given that small firms grow faster than large firms (Evans (1987)), there are two alternatives for small firms to have lower leverage; by financing their growth either exclusively through retained earnings or through external equity. Most explanations for the positive relationship between firm size and leverage assume implicitly or explicitly that external equity is prohibitively expensive for small firms and hence small firms’ financing should come exclusively from internal funds.2 There is also evidence that firms prefer internal financing to external financing.3 According to the pecking order theory (Myers and Majluf (1984)), adverse selection costs of external equity are much greater than those of debt. 1 For example, see Titman and Wessels (1988), Rajan and Zingales (1995), Graham, Lemmon, and Schallheim (1998), Hovakimain, Opler, and Titman, (2001), Booth et al. (2001) and Fama and French (2002). However, Faulkender and Petersen (2006) find a weak or negative relationship between the leverage and firm size. 2 See, for example, Frank and Goyal (2003), Leary and Roberts (2005), Strebulaev (2006), and Kurshev and Strebulaev (2006) for such arguments. 3 See Hovakimian, Opler, and Titman (2001) and Hovakimian, Hovakimian, and Tehranian (2004). 1 Issuance costs are also much greater for equity than for debt.4 Facing such high adverse selection/transaction costs, small firms should avoid issuing equity by all means. Hence the literature has paid little attention to the potential role of external equity in relaxing financing constraints of small firms in debt financing. We suggest the desire for “financial flexibility” as an alternative explanation for small firms’ low leverage and yet their reliance on external equity financing. Recently, the survey results of Graham and Harvey (2001), Bancel and Mittoo (2004), and Brounen et al. (2004) show that corporate managers explicitly express that they are mostly concerned about “financial flexibility” in their capital structure decisions. We first examine the concept of financial flexibility closely, paying special attention to those features of flexibility brought to light by recent management and organization literatures. The term is very broad and has many legitimate uses that need not be forced under a single definition. At the same time it will be necessary to define the term more clearly so as to avoid the confusion from its various uses in the finance literature. Thus, we first develop a concept of financial flexibility and then investigate the relevance of financial flexibility to capital structure decisions. We define financial flexibility as the degree of capacity and speed at which the firm can mobilize its financial resources in order to take reactive, preventive and exploitive actions to maximize the firm value. We are persuaded that all of the uses of flexibility pertinent to the finance literature are encompassed by its reactive, preventive and exploitive nature. In view of financial flexibility, change in profit (especially loss) can be important determinant of leverage. Specifically, firms with negative retained earnings (from the accumulation of losses) are likely to have little financial flexibility and debt capacity but ample needs for additional cash. Our main hypothesis is that firms with negative retained earnings are more likely to issue equity to build up cash holdings in order to preserve financial flexibility and hence have low leverage. The corollary to this hypothesis is that cash holdings will be negatively associated with leverage. We also examine if small firms’ lower leverage can be 4 Altinkilic and Hansen (2000) find that equity issuing costs are on average 5.38% of the issue proceeds while debt issuing costs are on average 1.09%. Leary and Roberts (2005) also report significantly larger equity issuance costs. 2 explained by the consideration of financial flexibility focusing on the relationship between firm size and leverage. We find that large firms retain much more earnings than small firms and that low leverage for small firms results from external equity financing rather than internal funds. While small firms avoid debt financing, they are much more active in tapping into external equity capital. Firms with negative retained earnings have lower leverage ratios and issue several times more equity than firms with positive retained earnings. We also find that small firms have negative retained earnings with more cash holdings than other firms. Thus, our findings are consistent with the argument that small firms build financial flexibility through cash holdings and equity financing to cope with their “abnormal” periods of earnings shortfalls (DeAngelo and DeAngelo (2006)). We further show that firm size has an overall strong and significant positive association with leverage ratios. However, the positive relationship between firm size and leverage ratios are substantially weakened or reversed for large firms when we divide firms re-estimate regressions for firms divided into small/large and positive/negative retained earnings. Also, negative retained earnings dummy variables are associated with significant and positive coefficient estimates, suggesting lower leverage ratios for firms with negative retained earnings. On the other hand, when we include retained earnings as a continuous variable in the subgroup regressions, positive retained earnings are significantly and negatively associated with leverage ratios, whereas negative retained earnings show less economically and statistically significant association with leverage ratios. Thus, our results show that firms with negative retained earnings build up cash holdings through equity financing, lowering leverage ratios, whereas firms with more positive retained earnings also have lower leverage ratios through the accumulation of earnings (as a means of building financial flexibility). Overall, the relationship between leverage and firm size is not clear. Our study brings new evidence to bear on an important issue in the capital structure literature. The literature has wrestled with the problem of sorting out the effects of adverse section costs of asymmetric information on capital structure.5 On the one hand, the liter5 For example, see Myers and Majluf (1984), Viswanath (1993), Chang and Dasgupta 3 ature finds that larger firms tend to issue more debt relative to equity than smaller firms and hence appear to provide a better fit for the pecking order theory (Shyam-Sunder and Myers (1999) and Frank and Goyal (2002)). On the other hand, our results show that small firms issue equity and raise up cash holdings despite having low leverage. Lemmon and Zender (2004) provides a justification for equity issuances that equity issuers are prevented from issuing debt because of concerns over financial distress or to preserve financial slack for future investment. Further, Fama and French (2002) and Leary and Roberts (2005a) show that firms are more likely to use equity financing as investment increases and/or cash flow decreases but the majority of equity financings occur when firms still have sufficient debt capacity to fill their investment needs. However, small firms in our sample appear to issue equity and build up cash holdings in order to cope with abnormal earnings shortfalls rather than to preserve financial slack. As an alternative explanation for violating the financing hierarchy, Fama and French (2005) and Leary and Roberts (2005a) suggest that firms are able to issue securities in a manner that avoids the adverse selection costs associated with information asymmetry. Alternatively, managers may time the market when information asymmetry, and the corresponding costs, are low so that deviations from the hierarchy do not incur a significant penalty.6 Our findings suggest that the external financing hierarchy suggested by the pecking order theory is revered due to the concern for financial flexibility. Consistent with our evidence, Byoun (2006a) finds that small debt-free firms raise much external equity while reducing debt and paying large dividend. Thus, financial flexibility can bear more important relevance to capital structure decisions than the adverse selection costs of asymmetric (2003), and Lemmon and Zender (2004) under the pecking order framework, and Frank and Goyal (2003), Fama and French (2002), Barclay and Smith (2005), Leary and Roberts (2005), Leary and Roberts (2005a), Strebulaev (2006) and Byoun (2006) under the tradeoff framework. 6 Rajan and Zingales (1995), Jung, Kim, and Stulz (1996), Pagano, Panetta, and Zingales (1998), Hovakimian, Opler, and Titman (2001), Baker and Wurgler (2002), and Leary and Roberts (2005a)) examine managers’ market-timing attempts. The survey results in Graham and Harvey (2001) suggest that managers issue equity following an increase in stock price. 4 information. Our findings suggest that small firms have lower leverage ratios, not because of internally generated funds or additional debt financing (as implied by the pecking order theory) but because of additional equity financing (consistent with our financial flexibility hypothesis). Small firms build up cash holdings in order to preserve financial flexibility through external equity. Overall, asymmetric information falls short of providing a complete explanation for motivation behind firms’ external financing decisions. An alternative explanation should include the benefits and costs of financial flexibility, which may require a substantial alteration to the tradeoff argument which is based only on traditional costs and benefits of taxes, bankruptcy costs, agency costs, and transaction costs. II. The Concept of Financial Flexibility: A Literature Review The pecking order theory by Myers and Majluf (1984) assumes that firms desire to maintain “financial slack” to avoid the need for external funds. However, finding that managers value financial flexibility is not sufficient to prove that the pecking-order model is the true description of capital structure choice (Opler et al., 1999). Graham and Harvey (2001) make this point explicit: The most important item affecting corporate debt decisions is management’s desire for “financial flexibility,”... However, the importance of flexibility in the survey responses is not related to informational asymmetry (size or dividend payout) or growth options in the manner suggested by the pecking-order theory. In fact, flexibility is statistically more important for dividend-paying firms, opposite the theoretical prediction (if dividend-paying firms have relatively little informational asymmetry). Therefore, a deeper investigation indicates that the desire for financial flexibility is not driven by the factors behind the peckingorder theory. Despite managers’ contention that financial flexibility is an important factor in the decision-making process of managers, the capital structure literature has to date remained aloof to recognize and incorporate financial flexibility. Frank and Goyal (2005) reason, “the 5 stress on financial flexibility is interesting, but potentially open to a variety of interpretations. In our view the survey evidence is of interest, but it is best regarded as being interesting and suggestive, rather than providing definitive tests.” In addition to considerable ambiguity in the use of the term, judgments about flexibility are subjective and informal and flexibility levels are rarely monitored or even measured. Accordingly, dealing with financial flexibility may be criticized as being less than practical and based on speculation on the ability of a firm to respond to hypothetical future events. It is therefore not surprising that there is relatively little systematic study of financial flexibility in the capital structure literature.7 Graham Harvey (2001) see financial flexibility as “preserving debt capacity to make future expansions and acquisitions” or “minimizing interest obligations, so that they do not need to shrink their business in case of an economic down turn.” Gamba and Triantis (2005), in their attempt to model the value of financial flexibility, define, financial flexibility as “the ability of a firm to access and restructure its financing with low transaction costs.” They further elaborate by adding “financially flexible firms are able to avoid financial distress in the face of negative shocks, and to fund investment at low cost when profitable opportunities arise.” Donaldson (1969, 1971) uses “financial mobility” to describe “the capacity to redirect the use of financial resources in a manner consistent with the evolving goals of management as it responds to new information about the company and its environment.” Donaldson particularly relates financial mobility to capital structure decisions where the goal is to find the optimal mix of financing sources. Heath (1978) describes financially flexible company as one that can take corrective action that will eliminate an excess of required cash payments over expected cash receipts quickly and with minor adverse effect on its present and future earnings or on the market value of its stock. The American Institute of Certified Public Accountants (AICPA, 1993) adopts Heath’s view by defining financial flexibility as “the ability to take action that will eliminate 7 In contrast, a branch of real options literature has been developed to deal with “investment flexibility.” Gamba and Triantis (2005) note that most real options models are designed to measure the value of “investment flexibility” under the assumption of perfect “financial flexibility.” 6 an excess of required and expected cash payments over expected resources.” The Financial Accounting Standards Board’s (FASB) defines financial flexibility as “the ability of an entity to take effective actions to alter amounts and timing of cash flows so it can respond to unexpected needs and opportunities.” Most of the treatments of financial flexibility in the finance literature are more or less about the ability of a firm to meet its expected future needs through large cash flow, large unused borrowing capabilities, or large liquid assets. The importance of flexibility in a firm is well recognized in management and organization literature. Bueno-Campos (1992), Ahmed et al. (1996), Albizu-Gallastegui (1997), Hitt et al. (1998) and Volberda (1998) define “flexibility” as the ability to deliver cost-efficient responses quickly to changes in the business environment and to adapt and anticipate changes that affect the goals of firms. There are other views from different functional areas of business (See Koornhof (1998) for a more detailed review on this). For example, Pasmore (1994) view humans are the drivers of organization flexibility. Harrigan (1985) use the term “strategic flexibility” to refer to a firm’s ability to reposition itself in markets, change its game plan or dismantle its current strategies. Trigeorgis (1993) and Kulatilaka (1993) use the term “operating flexibility” to describe the ability of managers to revise operating decisions in response to favorable opportunities or deteriorating conditions. This includes switching from one project to another. Such operating options are critical when the environment is highly volatile and technology is flexible, thus permitting managerial intervention at little cost. Bernstein (1993) defines flexibility as the ability of an enterprise to take steps to counter unexpected interruptions in the flow of funds for reasons however unexpected. In this view, financial flexibility means the ability to borrow from a variety of sources, to raise equity capital, to sell and redeploy assets, and to adjust the level and the direction of operations in order to meet changing circumstances. Koornhof (1998) defines flexibility as an ability to take actions to reposition the resources and functions of the organization to new information and environment in a manner consistent with the evolving vision, strategies and goals of management. The definitions of flexibility as addressed in the management and organization litera- 7 tures recognize the “reactive” and “preventive” nature of flexibility while failing to include the “exploitive” nature of flexibility for uncertain competitiveness or environment. The combination of reactive, preventive, and exploitive nature of flexibility is more evident in Volberda (1998) who views flexibility in two different perspectives: internal flexibility as the firm’s capacity to adapt to the demands of the environment, while external flexibility as the firm’s capacity to influence their environment and thereby reduce their vulnerability. Following the Volberda’s (1998) notion of flexibility, we propose to regard the financial flexibility not as the passive accumulation of resources but as the degree of capacity and speed at which the firm can mobilize its financial resources in order to take reactive, preventive and exploitive actions to maximize the firm value. The choice of financial flexibility is pragmatic and avowedly relativistic; it is chosen because of its ability to bring the diverse uses of flexibility into meaningful comparative relationships. Actions initiated ahead of time are typically taken in anticipation of certain events, or in an attempt to change the rules of the game. When expectations are not met, or when events occur that have not been predicted, a firm may require flexibility after the fact. In these cases, attempts are made to correct a mistake or to capitalize on an unexpected opportunity. The point to note is that actions taken ahead of time, even in the absence of a specific goal, can create options that can be used at a later stage. When a new product unexpectedly becomes an industry standard (e.g., Apple’s iPod), resulting in a rapid expansion of the market demand, exploitive maneuvers are important to focus resources and to rapidly capitalize on spontaneous opportunities. The speed is critical. According to our definition, financial flexibility is a function of uncertainty; not just about future cash flows but also about organization and environment. If the business environment is more turbulent and competitive (development stage in the life cycle), there will be more demand for flexibility to cope the uncertainty. Flexibility arises from a formal decision problem in which the choice from future options are affected by the choice made now (Gerwin, 1993). In other words, the decision on flexibility made in the present impacts on the options management will have available in the future in response to unforeseeable change. Financial flexibility is future oriented. It would be fundamentally inappropriate of a CFO of a company to say that his or her job is to maximize flexibility for 8 the organization. Thus, maximizing the firm value should be the ultimate goal of optimizing financial flexibility. It is apparent that certain aspects of financial flexibility have been addressed in the literature. For example, Goldstein, Ju, and Leland (2001) note that a firm with low leverage today preserves the subsequent option to increase leverage. Byoun (2006) find evidence that firms preserve borrowing capacity to finance future investment or growth opportunities. Graham (2000) shows that firms preserve debt capacity to make future expansions and acquisitions. Motyka, Leuca, and Fawson (2005) also find that financial institutions hold excess liquidity to cope with the unpredictable nature of loss (infrequent but high impact risk) in order to achieve a competitive advantage for aggressive pricing and better margins. III. Financial Flexibility and Leverage: the Hypotheses DeAngelo and DeAngelo (2006) note that firms can develop potential sources of future financial flexibility through cash accumulation, the preservation of debt capacity, and equity payouts. According to their argument, in “normal” periods, mature firms maintain low leverage and high payouts, thus preserving the firm’s option to borrow or issue equity in the future while limiting agency costs on cash balances. In “abnormal” periods characterized by unanticipated earnings shortfalls or profitable new investment opportunities, the firm issues securities, either debt or equity, depending on the trade-off between benefits and costs of issuing now versus preserving the option for the future. Thus, in view of financial flexibility, change in profit (especially loss) can be important determinant of leverage. We identify firms in those “abnormal” periods of unanticipated earnings shortfalls according to retained earnings. Retained earnings are accumulation of firms’ reinvested profits over time. Negative retained earnings reflect firms’ earnings shortfalls over time. Even a little debt may cause firms with negative retained earnings to be in financial distress. The limitation on debt issuance that results from the risk of asset substitution (Jensen and Meckling (1976)) are more important for firms with negative retained earnings. Firms with negative retained earnings lack investible funds for their profitable investments and hence sources of free cash flow tend to be relatively less for them, and thus reducing the ben- 9 efit of debt that limits the scope of overinvestment and perquisites by managers (Jensen (1986), Stulz (1990) and DeAngelo and DeAngelo (2006)). Hence the benefits of debt are less helpful both in terms of the sources and uses of free cash flow. Another benefit to the use of leverage is its signal to the market about the quality or riskiness of the firm (Ross (1977), Leland and Pyle (1977), and Heinkel (1982)). However, debt financing renders firms with negative earnings vulnerable to predatory strategies such as price wars by established firms to exhaust vulnerable firms financially (Poitevin (1989)), thus deteriorating financial flexibility. In addition, debt covenant often carry restrictions on financing and investment decisions that are especially cumbersome for small, growing firms. Accordingly, small firms with negative retained earnings have little incentive to use leverage to signal their quality. Overall, small firms with negative retained earnings are likely to have little financial flexibility and debt capacity but ample needs for additional cash. On the other hand, equity issues neither require collateral or restrictive covenants, nor accentuate moral hazard problems that are associated with leverage, nor raise the probability of financial distress. Thus, our main hypothesis is that firms with negative retained earnings are more likely to issue equity than debt and have low leverage than firms with positive retained earnings. We also hypothesize that small firms’ lower leverage can be explained by financial flexibility consideration. A firm can also develop financial flexibility through cash accumulation (DeAngelo and DeAngelo (2006)). On the one hand, cash holdings increase financial flexibility. On the other hand, it increases agency costs. Leverage can mitigate agency costs, but leverage in turn reduces future financial flexibility. As noted above, firms with negative earnings are likely to be in need of financial flexibility while constrained in borrowing and with little concern for agency costs and thus they can accumulate cash holdings through equity financing in order to preserve financial flexibility. Accordingly, we expect that cash holdings are negatively associated with leverage ratios. II. Data The initial sample consists of all available U.S. firms for the period of 1971–2005 from the annual Compustat files. Following previous studies, we exclude financial firms and 10 regulated utilities from the sample.8 We also require firms to have positive total assets, book and market value of equity and net sales. These variables are used to deflate other variables and it is difficult to interpret the results when they have non-positive values. We also delete observations with missing or non-positive values for the number of shares outstanding (Compustat item 25) and stock price at the end of the fiscal year (item 199). Accordingly, we drop bout 8 % of firm-year observations in the sample that have non-positive total assets market value of equity or net sales. After these requirements are applied, the sample consists of 179,418 firm-year observations. While Shyam-Sunder and Myers (1999) and Myers (1984) argue that there are rational reasons for managers to specify debt targets in terms of book values, Titman and Wessels (1988) and Welch (2004) are inclined toward the use of debt level measured at market value. Accordingly, we estimate the models using total (item 9 + item 34) and long-term (item 9) debt ratios measured with both book and market value of total assets. III. Estimation and Results A. Firm Size and Leverage In order to examine the relationship between firm size and leverage, we divide the sample into size deciles each year and report the leverage ratios measured in long-term and total debt to book/market value of assets. The market value of assets equals total assets (item 6) minus total equity (item 216) minus balance sheet deferred taxes and investment tax credit (item 35) plus the market value of common equity (price (item 199) times shares outstanding (item 54)) plus preferred stock liquidating value (item 10, replaced by the redemption value of preferred stock (Item 56) when missing).9 We delete all observations with leverage 8 Financial firms are represented by SIC codes 6000-6799 and utilities by SIC codes 48004999. These firms have very different capital structures and their financing decisions may not convey the same information as non-financial and non-regulated firms. For example, a relatively high leverage ratio is normal for financial firms, but the same high leverage ratio for non-financial firms may indicate possible financial distress. 9 The results does not change when we exclude deferred taxes and investment tax credit or include convertible debt (item 79) in the definition of book equity as in Alti (2006) and Kayhan and Timan (2006). 11 ratios less than zero or greater than one.10 We define size in three different ways based on book value of total assets (item 6), market value of total assets and net sales (item 12), but the results are similar and we report only those based on the book value of total assets. Table I Panel A of Table I shows that regardless of the various definitions of leverage ratios, there is a positive relationship between firm size and leverage ratio especially for smaller size deciles. However, the positive relationship between firm size and leverage is not clear for firms in the largest three deciles. We also report the percentage of zero-debt firms in each size decile. Small firms are associated with much more zero-debt firms than large firms. Byoun (2007) suggests that zero-debt firms are constrained by debt market while unconstrained by equity market. In order to examine whether the negative relationship between firms size and leverage is driven by these zero-debt firms, we report the results excluding zero-debt firms in Panel B of Table I. Even though the leverage ratios of small firms increase without the zero-debt firms, the positive relationship between size and leverage ratio are still present for smaller size deciles. Thus, our results confirm that there exists fairly strong positive relationship between firm size and leverage except for firms in the largest three deciles in which the positive relationship is weakened or reversed. Table II Faulkender and Petersen (2006) argue that market frictions may cause firms to be rationed by their lenders, leading some firms to appear under-levered relative to unconstrained firms. Thus, when estimating a firm’s leverage, it is important to include not only 10 Without this requirement, the average book leverage ratio of the sample firms in the first size decile are greater (but market leverage ratios are smaller) than firms in larger size deciles since there are a few firms with book leverage ratios greater than one in the first size decile. When we winsorize leverage ratios at 99 percentile, there still exist firms with leverage ratios greater than one. 12 determinants of its desired leverage (the demand side) but also variables that measure the constraints on a firm’s ability to increase its leverage (the supply side). Following Faulkender and Petersen (2005) and Lemmon and Zender (2004) we use firms’ long-term credit ratings (item 280) as a measure of accessibility to the public debt markets. Rating information is available only from 1985. Accordingly we divide the sample into two subperiods into before and after 1985, which also allows us to examine any discernable change in the relationship between firm size and leverage. For the period of 1971-1984, the relationship between firm size and leverage is positive and monotonic, whereas the relationship is weak or negative for firms in the largest three deciles for the period of 1985-2005. The results show that small firms rarely have long-term credit ratings and most ratings are concentrated in the largest three deciles. The lack of available credit ratings for small firms may indicate that these firms have relatively less debt capacity and hence lower leverage. Our results explain why Faulkender and Petersen (2006) find a negative relationship between leverage and firm size. The sample in Faulkender and Petersen (2006) includes only firms with credit ratings that are mainly from the largest size deciles for the period since 1985 and these firms show a weak or negative association between firm size and leverage. B. Firm Size, Cash Holdings, Retained Earnings and External Financing Activities In order to examine weather the lower leverage for small firms results from accumulated internal equity (as suggested by the pecking order theory) or external equity (as suggested by the financial flexibility hypothesis), we report retained earnings (item 36), net long-term debt issue (item 111 - item 114), net total debt issue (item 111 − item 114 − item 301 if item 318 = 1 and item 111 − item 114 + item 301, otherwise)11 and net new equity issue (item 108 - item 115) as proportions of total assets. We also examine the ratio of 11 Changes in current debt (item 301) represent an increase in working capital for format code 1 but a decrease in working capital for format codes. 13 cash and marketable securities to total assets ([item 162 + item 193] / item 6)12 . We drop observations with missing values in any of the reported variables. Table III Table III reports the results. The results in Panel A show that small firms tend to have more cash holdings while having less retained earnings than large firms. In fact, the average retained earnings are negative for firms in smaller size deciles. Thus, small firms’ growth is not likely to come mainly from internal equity. Small firms’ long-term or total debt financing is miniscule compared to that of large firms. On the other hand, small firms’ equity financing is phenomenal. The firms in the first and second size deciles issue equity on annual average 25% and 12% respectively of total assets. Our results can be driven by IPO firms that are more likely to be in small size deciles. In order to examine the IPO effects, we identify the IPO date from Compustat and designate the first fiscal year ending after the IPO date as a IPO year. We also identify the first year appearing in the Compustat for those that do not have IPO dates but the Computat begins its coverage during our sample period and treat it like the IPO year. The results excluding these IPO years are reported in Panel B. They show that the magnitude of external equity raised by small firms become smaller without IPO years, but it is still significantly greater than that raised by larger firms. Another possibility is that the results could be driven by a few outliers especially in small size deciles. To address this concern we reproduce results with winsorization of the equity financing variable at 1st and 99th percentiles. Again the results in Panel C show the same result that the small firms heavily rely on external equity with little debt. The pattern remains intact but only with less magnitudes when we winsorize the variable with greater cutoff percentiles. Overall, firm size is negatively associated with cash and debt financing whereas positively 12 Including accounts receivable (item 2) in addition to cash and marketable securities produces almost identical results. 14 associated with retained earnings, equity issue and dividend payout ratio. Thus, small firms appear to have lower leverage ratios, not because of internally generated funds or additional debt financing but because of additional equity financing. Small firms also build up cash holdings in order to preserve financial flexibility through external equity. C. Firm Size, Retained Earnings and Leverage In order to disentangle the relationship between firm size and leverage ratios while accounting for the strong association of firm size with retained earnings, we first examine the leverage ratios for firms divided into negative and positive retained earnings groups within each size decile. Panel A of Table IV shows cash holdings, dividend, and leverage ratios for each group. Interesting is the finding that the smaller firms (in size deciles below 6) with negative retained earnings hold more cash balances than similar size firms with positive retained earnings probably as a means of preserving financial flexibility. On the other hand, large firms with negative retained earnings tend to carry less cash balances with higher leverage ratios than large firms with positive retained earnings. The market value leverage ratios for firms with negative retained earnings are always smaller than book value leverage ratios because negative retained earnings increase market value of total assets when we subtract total equity from total assets to replace with the market value of equity. Since the portion of negative retained earnings relative to total assets are significantly greater for small decile firms, smaller firms (in 1 to 4 size deciles) with negative retained earnings have higher book leverage ratios whereas lower market-value leverage ratios than firms with positive retained earnings in the same size deciles. Thus, firms with negative retained earnings appear to have higher book leverage ratios because of less total assets stemming from negative retained earnings. The results suggest that the relationship between firm size and leverage within smaller size deciles (less than decile 5) can depend on whether the leverage is measured in terms of book or market value because of the significant number of firms with negative retained earnings. Firms with positive retained earnings pay higher dividend than firms with negative retained earnings. Thus, there are important differences between positive 15 and negative retained earnings groups. Panel B of Table IV shows that firms with negative retained earnings issue much more equity than those with positive retained earnings. The larger equity issues of small firms are driven by firms with negative retained earnings as they issue equity to raise cash while maintaining financial flexibility. This finding is consistent with our hypothesis that small firms with negative retained earnings issue equity rather than debt to preserve financial flexibility. Larger firms with negative retained earnings tend to issue both debt and equity, but their equity issues are significantly greater than those of large firms with positive retained earnings. Table IV D. Regression Results We first estimate regressions with variables typically used in previous cross-sectional studies as well as additional variables we expect to have significant impacts on leverage ratios. The following firm and industry characteristic variables are included: Retained = retained earnings divided by total assets; N egRet = dummy variable equal to one for the year with negative retained earnings and zero otherwise; Zero = dummy variable equal to one for the year with zero debt and zero otherwise; IP O = dummy variable equal to one for IPO year and zero otherwise; Cash = Cash and equivalents divided by total assets; M ed = industry median debt ratio (based on two-digit SIC or Fama and French (2002) industry groupings). According to Frank and Goyal (2004), the industry median leverage is an important determinant of a firm’s leverage ratio, acting as a proxy for several factors, including intangibility, regulation, stock variance, uniqueness, purchasing manager’s sentiment index, etc.; 16 T ax = marginal tax rate equal to the statutory tax rate if the firm reports no net operating loss carryforwards (item 52) with positive pretax return (item 170) and zero otherwise. The statutory taxes are 48% from 1971 to 1978, 46% from 1979 to 1986, 40% in 1987, 34% from 1988 to 1992, and 35% from 1993 to 2003. Plesko (2003) shows that this binary measure captures the marginal tax effects; OI = operating income (item 13) divided by total assets (item 6). A firm with higher earnings could prefer to operate with either lower or higher leverage. Lower leverage might occur, as higher retained earnings mechanically reduce leverage, or if the firm limits leverage to protect the franchise responsible for producing these high earnings. Higher leverage might reflect the firm’s ability to meet debt payments out of its relatively high earnings cash flow; M B = market-to-book ratio of assets.13 A higher M B is generally taken as a sign of more attractive future growth options, which a firm tends to protect by limiting its leverage; LnA = log of total assets (item 6) as a measure of firm size. Larger firms tend to: have more leverage (perhaps because they are more transparent); have lower asset volatility; or naturally sell large enough debt issues so that the fixed costs of public borrowing are not prohibitive;14 DEP = depreciation and amortization (item 14) as a proportion of total assets. Firms with more depreciation expenses have less need for the interest deductions associated with debt financing; F A = fixed assets (item 8) divided by total assets. Firms operating with greater tangible assets have a higher debt capacity; 13 The results do not change when we exclude deferred taxes and investment tax credit or include convertible debt (item 79) in the definition of book equity (as in Alti (2006) and Kayhan and Titman (2006)). 14 The results are not affected whether the size is defined in terms of market value of assets or of net sales (item 12). 17 RN D = research and development expenditures (item 46) divided by net sales (item 12). RN D can be taken as a proxy for future expected investment (Fama and French (2002)). They also serve as an additional proxy for non-debt tax shields. We set missing values as zero and include a dummy variable; D RN D = dummy variable that equals one for firms with missing RN D and zero otherwise; DIV = common stock dividends (item 127) divided by total assets. DIV controls for possible trade-off between debt and dividend in reducing agency costs of free cash flow (Fama and French (2002)); and AZ = Altman’s Z-score modified by MacKie-Mason (1990): (3.3EBIT (item 178) + sales (item 12) + 1.4 retained earnings (item 36) + 1.2 working capital (item 4 - item 5)) divided by total assets. Altman’s Z-score measures the ex ante probability of distress (Graham (1996, 2000)). We winsorize all the variables deflated by total assets at the 1st and 99th percentiles except for industry median (M ed), dividend (DIV ), and R&D (RN D) which are winsorized only at the 99th percentile because many firms have a value of zero for these variables. Table V reports two sets of estimation results for each dependent variable, with and without variables N egRet, Zero, IP O, and Cash. These additional variables are not frequently used in previous studies and we want to see if the results are different when they are included. The coefficient estimates on firm size (LnA) are highly significant and positive in all regressions. Thus, there is a fairly strong positive relationship between leverage and firm size even after controlling for the additional variables. All the other coefficient estimates are significant with the same signs found in previous studies. When we include N egRet, Zero, IP O and Cash, the coefficient estimates on these variables are negative. This result suggests that firms with negative retained earnings have significantly lower leverage. Also, firms holding more cash balances tend to have lower leverage. In order to further examine the effect of retained earnings on the relationship between firm size and leverage, we divide the firm into four groups: large/small firms (deciles greater than/less than or equal to 5) with positive/negative retained earnings. The reasons we 18 divide firms this way are that the effect of negative retained earnings could be different between small and large firms and that in our previous results the relationship between leverage and firm size is rather ambiguous for larger firms. We run the same regressions as in Table V for these subgroups except that we replace the negative retained earnings dummy variable with retained earnings (Retained) winsorized at the 1st and 99th percentiles. The estimation results are reported in Table VI. The results show that the coefficient estimates on size (LnA) tend to be positive for small firms (in Panels A and B) but negative or insignificant for large firms (in Panels C and D). Thus, the positive relationship between firm size and leverage holds true only for small firms. This finding is consistent with the univariate results that show lower leverage ratios for the largest decile firms. The coefficient estimates on retained earnings (Retained) are highly significant and negative for firms with positive retained earnings (in Panels A and C), whereas they are economically or statistically insignificant for firms with negative retained earnings (in Panels B and D). As we observed in Table IV, the effects of negative retained earnings are different between book and market value leverage ratios: negative retained earnings lower the book leverage, which results in small negative coefficient estimates on retained earnings in book-value-leverageratio regressions; and negative retained earnings increase the market value leverage, which results in small positive or insignificant coefficient estimates on retained earnings in marketvalue-leverage-ratio regressions. Overall, our results suggest that the positive relationship between leverage and firm size hold for small firms but not for large firms when we control for retained earnings which measures the degree of financial flexibility. The firm size up to a certain level appears to be important for leverage but its importance disappears once firms outgrow that level. Small firms’ lower leverage ratios appear to result from their concern for financial flexibility (issuing equity and building up cash holdings) and large firms with positive retained earnings also have lower leverage as they accumulate internal funds to preserve financial flexibility or to finance growth opportunities. Thus, the relationship between leverage and firm size appears to be positive for small firms but negative for large firms. 19 VI. Summary and Conclusions We examine the relationship between firm size and leverage in the view of financial flexibility. We define financial flexibility as the degree of capacity and speed at which the firm can mobilize its financial resources in order to take reactive, preventive and exploitive actions to maximize the firm value. We hypothesize that firms with negative retained earnings are likely to have little financial flexibility and debt capacity but ample needs for additional cash. Accordingly, firms with negative retained earnings are more likely to issue equity to build up cash holdings (a means of financial flexibility) and hence have low leverage. The corollary to this hypothesis is that cash holdings will be negatively associated with leverage. We also examine if we can explain the positive relationship between firm size and leverage in the view of financial flexibility, given that many small firms have negative retained earnings and are in need of financial flexibility. Consistent with our hypothesis, firms with negative retained earnings issue several times more equity than firms with positive retained earnings. While small firms avoid debt financing, they are much more active in tapping into external equity capital. We also find that small firms often have negative retained earnings with no less cash holdings than other firms and that small firms with negative retained earnings have lower leverage than firms with positive retained earnings. We further show that firm size has an overall strong and significant positive association with leverage. However, the positive relationship between firm size and leverage are substantially weakened or reversed for large firms when we control for retained earnings. Our regression results, coupled with univariate results, suggest that small firms with negative retained earnings build up cash holdings through equity financing, lowering leverage ratios, whereas large firms with positive retained earnings accumulate earnings (as a means of building financial flexibility), resulting in lower leverage ratios. Thus, the relationship between leverage and firm size is unclear—we need more research on this issue. Overall, small firms appear to have lower leverage ratios, not because of internally generated funds or additional debt financing but because of additional equity financing. Small firms also build up cash holdings in order to preserve financial flexibility through external equity. 20 This finding can be explained by neither of the pecking order theory and the tradeoff theory—the pecking order may be reversed for small firms that prefer external equity to debt financing while the tradeoff theory may miss out some important aspects of capital structure decisions. In conclusion, the benefits and costs associated with financial flexibility influence firms’ capital structure decisions—but not in the manner hypothesized by the traditional trade-off theory. Thus, a substantial alteration may be required to the tradeoff argument which is based only on traditional costs and benefits of taxes, bankruptcy costs, agency costs, and transaction costs. 21 References Almeida, Heitor and Murillo Campello, 2005, Firm financing-investment interactions: Evidence from debt and equity issues, New York University and University of Illinois Working paper.
