Do private equity investors take firms private for different reasons?∗ Jana P. Fidrmuc† Peter Roosenboom‡ Warwick Business School RSM Erasmus University Dick van Dijk§ Econometric Institute Erasmus University Rotterdam April 2007 Abstract In recent years, the going private market experienced a considerable boom in size and also became more interesting for private equity investors. This paper shows that the higher involvement of private equity investors affects the going private market as these investors approach firms with different characteristics relative to the traditional management buy-outs. Our results on a sample of 212 UK going private transactions completed in the period 1997-2003 suggest that private equity backed deals differ from management sponsored deals without any backing of private equity investors in four ways. First, even though both types of deals suffer from market undervaluation, the mis-pricing is larger for management sponsored deals. Second, it is only management sponsored deals that suffer low financial visibility as their stock’s analyst coverage and frequency of trading are low. Third, Jensen’s free cash flow hypothesis seems not to apply to private equity backed deals as they have shortage of cash, low debt levels, and pay high dividends. Finally, the two types of deals differ in ownership structure. Private equity backed deals seem to have higher ownership by financial institutions and their ownership is less concentrated.

Box 1738, NL-3000 DR Rotterdam, The Netherlands, e-mail: [email protected] 1 Introduction We investigate whether private equity investors take firms private for different reasons than the firm’s managers. The paper builds on the heterogeneity hypothesis of Halpern et al. (1999) who argue that “the population of LBOs is heterogeneous and understanding the differences among LBOs is important in understanding both why each type of firm engaged in this transaction and what they did after the transaction” (page 282). We use this idea of heterogeneity to highlight the involvement of private equity funds. While undervaluation, low financial visibility, high managerial ownership and free cash flow are key factors motivating management to take their firm private, we examine whether private equity investors pursue similar goals or may have other incentives to be involved in a public to private transaction. Several empirical papers have examined the reasons for why publicly listed firms decide to go private (see Maupin et al., 1984; Lehn and Poulsen, 1989; Denis, 1992; Opler and Titman, 1993; Halpern et al., 1999 for US and Weir et al., 2004, 2005 for the UK). However, most of this empirical evidence investigates the going private deals of the 1980s, focuses on testing of Jensen’s (1986) free cash flow hypothesis and does not consider the effect of private equity involvement. Recently, private equity houses have considerably increased their investment and at the same time changed their strategy concerning the going private market. In the 1980s, private equity investors often engaged in highly leveraged transactions, many of which were seen as hostile by incumbent management. Nowadays, private equity investors are often looking to partner with management. They are interested in sound strategic reasons to justify any going private deal and low valuation on its own is not enough. In fact, private equity investors are after fundamentally strong businesses. Their typical target is a long-term player, has leading market share within their defined niche, and has a strong customer base, good growth potential and good margins (The Deal, 24 November 2003). Operational improvements have become more important than they were before in the 1980s (Business Week, 27 February 2006). In this paper, we conjecture that going private deals that have backing of a private equity house have different characteristics and go private for different reasons than 1 management buy-outs that do not have the backing of a private equity house. In other words, the population of going private firms is not homogeneous with respect to the reasons for the deal and pooling all deals together may result in biased results. The population of public to private (PtP) deals can be partitioned into separate groups: (i) private equity backed going private transactions and (ii) management buyouts where management initiates the deal without any direct involvement of private equity funds (we refer to this group as ‘management sponsored deals’). We show that these two groups have their own unique characteristics and their own reasons for going private. To cover the whole population of PtP deals, our analysis also includes a third type of ‘other’ going private transactions that are initiated by different parties such as non-executive directors, wealthy private individual investors, industrial firms or financial investors that are not private equity investors. This group is included for completeness of our model. That is, we want to be sure that any differences found between the private equity backed deals and management sponsored deals are not arising due to omitting the remainder of the going private firms. We consider four different aspects that may motivate management sponsored deals and argue that private equity sponsored deals do not share these incentives as they target firms with shortage of cash that can be turned around and make the investment to pay off (Gompers and Lerner, 2001). The first of our hypotheses is that market undervaluation may motivate managers to take their firms private. However, information asymmetry and undervaluation may be less important for private equity backed deals because private equity investors are primarily interested in a strategic justification for their transactions (Gompers and Lerner, 2001). The second hypothesis concerns the recently recognized proposition that low financial visibility plays an important role in going private decisions as it undermines the main benefits of public ownership (see Boot et al., 2006 and Mehran and Peristiani, 2006). Again, we suggest that management sponsored deals are motivated by low financial visibility of their stock because firm managers weight the costs and benefits of the public listing. In contrast, private equity investors profit from the strategic 2 advantages of the deal and so financial visibility may be less important for them. Third, we explore the free cash flow idea of Jensen (1986) separately for the two groups of going private transactions. In particular, we propose that private equity backed firms may have less agency problems associated with free cash flows as, in fact suggested by Gompers and Lerner (2001), they are more likely to have low cash balances. Finally, we highlight the differences in pre-buyout ownership structure between the two types of firms. Elitzur at al. (1998) propose that managers who have a large amount of their personal wealth invested in the company may be more likely to decide in favor of a going private deal. In contrast, we argue that private equity backed deals may have high institutional ownership as institutional investors may be willing to support their deal. We note that several of the above hypotheses have not been explored in this context so far, which constitutes another contribution of this paper. In our empirical analysis, we examine a sample of 212 UK going private transactions that occurred during the period 1997-2003 and compare them to randomly selected UK firms that remained listed on the London Stock Exchange.1 Using multinomial logistic models, we find support for our conjecture that going private firms are heterogeneous with respect to the private equity involvement in the deal and, at the same time, the two groups of going private firms are different from the firms that remained public. First, the results suggest that even though both types of deals suffer market undervaluation, the mis-pricing is significantly larger for the management sponsored deals. Second, we show that it is only management sponsored deals that suffer from low financial visibility as they fail to attract sufficient investor interest. The private equity backed deals are not distinguishable in this respect from the control group of firms that remain public. Third, our results suggest that the free cash flow hypothesis does not apply to private equity backed deals. As expected, they seem to have lower cash balances and, at the same time, pay higher dividends than management buyouts. Finally, the two types of deals are 1 In the US, the total value of deals went up to $65 billion over the period 1997-2002 (Renneboog and Simons, 2005). The UK deals total £30 billion over the period 1997-2003. This makes the UK going private market second only to that in the US. 3 heterogeneous in pre-buyout ownership structure. Our results show that firms in private equity backed deals have higher ownership by financial institutions and their ownership is less concentrated relative to management sponsored deals. The plan of the paper is as follows. In Section 2, we put forward our four heterogeneity hypotheses. Section 3 describes our dataset, methodology and provides basic descriptive statistics of our sample. Section 4 presents our empirical results. Section 5 concludes. 2 Heterogeneity in going private transactions In this paper, we propose that private equity involvement in going private transactions is associated with different firm characteristics compared to transactions initiated and led solely by managers. Thus, we argue that in order to get a better picture of the reasons and characteristics of going private transactions, we should not pool all going private firms together but rather separately evaluate the reasons for going private in two different types of deals: (i) going private transactions backed by private equity investors, and (ii) going private transactions led by the firms’ executive directors without any backing of private equity investors (management sponsored deals). As active private equity involvement in going private transactions is a relatively new phenomenon, the literature explaining the motives of private equity investors to engage in these deals is very limited.2 Therefore, it is not easy to come up with rigorous hypotheses backed up with theoretical models or previous empirical findings. The literature, however, is quite useful in providing explanations for the motives of managers (as opposed to private equity investors) engaging in the buyout deals. In fact, we form four relatively broad hypotheses explaining why firms go private: (i) undervaluation of the going private firms relative to their peers in the market; (ii) their low visibility in the form of illiquidity of their stock and low analyst coverage; (iii) high free cash flows and tax shields; and (iv) high managerial ownership. At the same time, we suggest that these four motivations may be less 2 Gompers and Lerner (2001) is one of the few references. 4 applicable to private equity backed deals as the general perception of private equity investors’ activities suggests that private equity houses are interested in turning companies around within a three to five year horizon and making decent returns on their investment (Business Week, 27 February 2006). Also Gompers and Lerner (2001) support this view. The following subsections explain the four possible ways in which the two types of going private transaction may differ. 2.1 Heterogeneity in undervaluation Due to information asymmetry between management and outside shareholders, it is possible that the market value of a company is above or below its fundamental value (Merton, 1987). In going private transactions, the perceived undervaluation may play an important role as it potentially limits management’s ability to use the benefits available to public companies as, for example, the accessibility of funds required to finance new investment projects or acquisitions (Allen and Gale, 1999; Pagano et al., 1998). A survey among US managers who underwent a going private transaction indicates that the perceived undervaluation is indeed one of the primary reasons for managers to take their firm private (Maupin et al., 1984). Moreover, undervalued firms are more likely to attract hostile takeover interest (Lehn and Poulsen, 1989) that may lead to managers losing their jobs (Lowenstein, 1985). Therefore, we conjecture that undervaluation of firms increases the likelihood of managers taking their firms private as this allows the managers to keep control over the firm at relatively low cost and avoid (hostile) takeovers. Outside investors may also value a company more than the current market value because they perceive unexploited growth opportunities. In particular, private equity investors may target firms because of poor management that has not been taking full advantage of the firms’ growth potential possibly due to a lack of cash (DeAngelo, 1990). Gompers and Lerner (2001) argue that private equity investors look for companies that have the potential to evolve in ways that create value and at the same time face problems in raising funds via regular bank debt or public equity. This aspect may be more important in the UK versus the US since the UK venture capital and buyout markets have traditionally been more closely linked (Toms and 5 Wright, 2005). In addition, private equity investors may also follow a ‘buy-andbuild’ strategy in which they focus on growth opportunities within an industry and hire new managers with industry experience as needed. In such a buy-and-build strategy the private equity investor acts as an industry consolidator taking over a number of smaller rival firms. In this case, the value of the going private transaction to the investor depends more on the investor’s previous portfolio investments rather than the firm being undervalued (Smit and DeMaeseneire, 2005). Moreover, it seems plausible that private equity investors have less superior information relative to the management concerning the undervaluation of the firm. In short, we predict that undervaluation plays a role in both types of going private transactions but to a different degree. Undervaluation is expected to be more important in management sponsored private equity transactions. In contrast, undervaluation is less important in transactions backed by private equity because these active investors could create additional value using their unique resources such as their network and industry expertise and do not have private information advantage. 2.2 Heterogeneity in visibility If a firm’s shares are thinly traded, being public may not be worth the cost (Bolton and von Thadden, 1998). Boot et al. (2006) highlight liquidity and low cost of capital as important benefits of public versus private ownership. Furthermore, thinly traded stocks have lower analyst coverage in general and are at risk of being neglected by investors when taking their investment decisions (Merton, 1987). Thus, firms that are not able to attract adequate level of investor recognition have to bear the high cost of stock exchange listing while not taking enough advantage of the benefits of being a public company (Mehran and Peristiani, 2006). Therefore, we propose that low financial visibility may motivate managers to take their firm private. In contrast, the predominant and most important economic activity for private equity investors is the restructuring of their targets. Often, it is argued that it is easier to fix a private company rather than a public one. This is because public shareholders are strongly focused on quarterly results, which often is in sharp conflict with long term strategic goals of multiyear restructuring efforts. Thus, going 6 private firms with private equity backing may actually want to hide from relatively high visibility and scrutiny of the public market. At the same time, private equity investors prefer projects where monitoring and selection costs are relatively low and where the information asymmetry costs are less severe (Amit et al., 1998). So, relative to the management sponsored PtP firms, we expect private equity backed deals to be associated with less problems in attracting financial visibility and investor recognition. 2.3 Heterogeneity in free cash flows Most of the empirical evidence concerning going private transactions so far is based on Jensen’s free cash flow hypothesis. Jensen (1986) proposes that debt-financed going private transactions may provide a solution to firms in cash-rich, slow growth and declining industries. The main argument maintains that firms with large cash balances but low growth prospects are vulnerable to conflicts of interest between managers and shareholders over payout and investment policies. To mitigate this problem, managers can increase dividends and thus provide payout of current cash that would otherwise be invested in low-return projects or be wasted. However, a promise of increased dividend is not credible as managers can easily reduce dividends in the future at low cost. In contrast, issuing debt in exchange for stock is a credible strategy to limit free cash flows because unpaid interests lead to bankruptcy. The empirical studies testing the free cash flow hypothesis in the context of going private transactions provide mixed results. Lehn and Poulsen (1989) document that undistributed cash flow is a significant determinant of a firm’s decision to go private. Also Opler and Titman (1993) show that high cash flow firms that also have a low Tobin’s q (which they use to measure future growth prospects) are more likely to undertake an LBO. In contrast, Kieschnick (1998) argues that after accounting for choice based sampling, outliers in the data, and potentially misspecified variables, prior growth rate and level of free cash flows are not significant determinants of the odds of going private for the Lehn and Poulsen (1989) dataset. Furthermore, Weir et al. (2004) also fail to find significance of free cash flows in determining the odds of going private for UK firms. All the empirical papers, however, pool all going 7 private firms together and treat them as a single homogeneous group. Halpern et al. (1999), in contrast, distinguish two groups of going private firms according to the level of management ownership before the transaction but do not test the free cash flow hypothesis on the two groups separately.3 We propose that private equity backed deals, as opposed to management sponsored deals, do not match the profile of Jensen’s cash-rich firms. Intuitively, firms that search for private equity backing are more likely to suffer low cash balances and high growth opportunities. (Gompers and Lerner, 2001). In contrast, managers of cash-rich firms with low growth prospects may see the potential of leveraged transactions as they may be ware of their ill-specified incentives and use the excess cash to fund the going private transaction or to service new debt and gain control over their firms (Fox and Marcus, 1992). Moreover, the leveraged transaction allows managers to avoid the prospect of hostile takeover and/or shared control with an active private equity investor who typically demands board representation and a say in the firm’s long-term strategy (Cotter and Peck, 2001). Therefore, we predict that large cash balances may motivate management sponsored going private transactions but not private equity backed deals. 2.4 Heterogeneity in pre-buyout ownership structure Halpern et al. (1999) and Elitzur at al. (1998) argue that managers who have a large amount of their personal wealth invested in the company may prefer to diversify their portfolio while keeping or increasing their control over the firm. Managers with large equity stakes therefore have incentives to initiate a leveraged buyout and use new debt to decrease their wealth invested in the firm. It is relatively inexpensive for these managers to acquire a majority of the votes and force the leveraged buyout given their large equity stakes and any potential information asymmetry (Elitzur et al., 1998). Thus, we expect that managers with high ownership stakes in their own firm are more likely to take their firm private and do not seek backing by private 3 In particular, they propose that for the group of low management ownership firms, third-party takeover pressures force management to consider a third party led buyout or face the prospect of hostile takeover. In the case of high prior management ownership group, managers hold large undiversified portfolios and so have an incentive to take cash out of their firm. 8 equity investors. Private equity investors typically look for support of a number of incumbent blockholders before they take a firm private. This increases their chances of the deal being successful. In fact, the private equity investor usually contacts the existing blockholders in order to receive irrevocable undertakings wherein the existing blockholders promise to accept the private equity investor’s offer (Wright et al., 2007). After receiving the support of several blockholders, the private equity investor makes a public offer for the remaining shares at the same price. These irrevocable undertakings are easier to obtain when ownership is concentrated in the hands of a small number of outside shareholders. Institutional investors may be of special importance as most of them are passive and not interested in monitoring management closely themselves (Faccio and Lasfer, 2000). They are likely to sell their shares in case they are able to negotiate a premium price and earn a return on their otherwise illiquid investment. Therefore, we expect that high institutional ownership increases the likelihood of a going private transaction backed by private equity. 3 3.1 Data and methodology Sample selection Our original sample consists of 221 non financial firms that have gone private in the United Kingdom during the years 1997-2003. We identify these public-to-private (PtP) transactions from the database of the Centre for Management Buyout Research (CMBOR). For all the PtP firms, we also obtain the offer documents accompanying the going private transaction from Thomson Research. We use these documents to determine whether the deal is backed by private equity investors or not. This is our primary classification criterion to decide upon whether a deal falls in the private-equity backed group. In case the transaction is not backed by a private equity house we further examine whether any of the firm’s executive directors are involved in the deal. If this is the case, the transaction is coded as a management-sponsored deal. In all other cases, the transaction is classified into the ‘other’ category. This category includes deals backed by non-executive directors, wealthy families or insti9 tutional investors other than private equity houses and is included for completeness of our model.4 We do not have data for 9 PtP firms and, therefore, our final sample of going private transactions consists of 212 firms that are relatively evenly distributed between 90 private equity backed deals, 69 deals led by management and not backed by private equity investors and 53 ‘other’ deals led by other parties. In order to get a more detailed picture of the characteristics of the going private transactions in general and the three individual types of going private transactions in particular, we contrast the going private firms with firms that remained publicly listed. We opt for a random sample of control firms that remained public: in each of the years of the sample period of 1997-2003 we randomly select 200 control firms from a population of around 1200 firms that continue to be publicly traded in a given year. The sampling procedure allows for a control firm to be included in the sample more than once. In total, we collect data on 1400 control firm-years that cover 960 different control firms. For both the PtP firms and control firms, we get market prices from Datastream, financial statement data from Worldscope, and hand-collect ownership structure and board composition information from Price Waterhouse Coopers’ Corporate Register (various issues). In the going private literature it is common to use a matched control sample of firms that remained public. Firm size and industry classification are the most commonly used matching criteria. In general, the sampling method – whether we use a random sample as in this paper or a matched sample – does not pose any advantages or disadvantages except for the case where the characteristics used for the matching process are important determinants of the going private process. We prefer random to matched sampling because we believe that firm size is a relevant factor influencing the decision to go private. Using a matched sample would not allow us to test for this possibility. 4 Note that the private equity backed deals may be both with and without management involvement. In fact, private equity funds often look for management involvement in their deal. We believe it is the presence of private equity involvement that matters for the deal characteristics. Private equity investors are attracted to certain type of firms and managers behave differently conditional on private equity interest. 10 3.2 Descriptive statistics Table 1 lists our variable definitions and Table 2 shows summary statistics for all PtP firms together, the three types of PtP deals separately, and the control firms. All variables are trimmed at the 1st and 99th percentiles, except the ownership and illiquidity variables. We test for differences in means and medians between the control firms and PtP firms and among the three types of PtP firms. We use a t-test for equal means allowing for unequal variances and a Mann-Whitney U-test for equal medians. Below we first discuss the differences between the complete sample of PtP firms versus the control firms and then we focus on the differences between the two main types of going private firms. The latter comparison highlights the heterogeneity idea proposed in this paper. We only discuss the statistically significant differences for both the mean and the median. - insert Tables 1 and 2 about here Firms that go private are valued less than control firms as indicated by their lower market to book ratios. They also experience more takeover rumours. PtP firms’ shares are traded less actively than the shares of the control firms and are followed on average by fewer analysts. Moreover, the going private firms have higher equity stakes held by executive directors and financial institutions than the control firms. As a result, ownership concentration, as measured by the Herfindahl index, is higher in PtP firms than in control firms. In addition, firms that go private have less cash and marketable securities, lower sales growth, higher payout ratio and are more profitable than control firms. Turning to the differences between the different groups of going private firms, we observe that the market to book ratio of the private equity backed deals (that we use as a measure of stock market valuation) is higher indicating that firms that go private with the help of private equity investors are less undervalued than the management sponsored deals. They also have higher analyst following and their shares are more actively traded. At the same time, the private equity backed deals are larger relative to the deals sponsored by management. Moreover, the private equity backed PtP 11 deals have significantly lower executive ownership and higher ownership by financial institutions relative to the management sponsored transactions. Also, their pretransaction ownership concentration is lower. Finally, we compute the free cash flow proxy of Lehn and Poulsen (1989) used in the going private literature so far. Table 2 shows that private equity backed deals have higher free cash flow in the previous year. However, DeAngelo and DeAngelo (2006) argue that the firm’s current cash flow is not a suitable measure of managerial opportunism as it does not reflect the stock of resources at managers’ disposal. What matters is managers’ access to the stock of liquid assets at all points in time which is better reflected in the firm’s cash and marketable securities. In fact, free cash flow is highly correlated with the firm’s profitability which indicates that it is restricted to affect managerial incentives only at ’a distribution point’ (DeAngelo and DeAngelo, 2006) and, thus, it may not be enough to encompass all resources at managers’ disposal and therefore is not able to generate empirically valid predictions. This suggests that the firm’s cash level is a more suitable proxy for company free cash at the disposal and discretion of the managers. Table 2 reports that private equity backed deals have less cash on their balance sheet than the management sponsored deals. 3.3 Model We employ multinomial logistic regression (MNLR) models to examine the heterogeneity hypotheses developed in the previous section. As mentioned before, we divide our sample of UK firms into four different groups: (1) private equity backed PtP deals, (2) management sponsored PtPs, (3) other PtPs, and (4) non-PtPs. We denote the observed group for firm i by the variable yi , which can take the discrete values 1, 2, . . . , M, where M = 4 in our case. In the MNLR model the probability that firm i will belong to group m, conditional on the (k × 1) vector of explanatory variables xi consisting of a constant and firm characteristics, is given by ′ exp(βm xi ) P [yi = m|xi ] = PM , ′ l=1 exp(βl xi ) 12 for m = 1, . . . , M. (1) For identification purposes, we set the coefficients for the non-PtP group of firms equal to 0, that is β4 = 0. Estimation of the coefficients in the MNLR model in (1) is straightforward by means of maximum likelihood, except for the following caveat. Our data set is not a random sample from the population of all firms. In particular, while we include all known PtP deals during the period 1997-2003, each year we only sample 200 of the firms that remain listed, which in total equal 1200, on average. This implies that PtP firms are considerably overrepresented in our sample compared to the underlying population of firms. Not accounting for this selective sampling would lead to biased estimates of the intercepts and incorrect standard errors for all estimated coefficients; see Kieschnick (1998) and Fok and Franses (2002) for detailed analysis of selective sampling in the context of binary and ordered logit models, respectively. The problem can be remedied by defining modified probabilities as γm P [yi = m|xi ] P̃ [yi = m|xi ] = PM , l=1 γl P [yi = l|xi ] for m = 1, . . . , M , (2) where γm is the fraction of firms in group m that is included in the sample. Hence, in our case γ1 = γ2 = γ3 = 1 while γ4 = 1/6. The correct likelihood function, which is used for parameter estimation then makes use of these corrected probabilities. The effects of the firm characteristics xi on the probabilities that a firm engages in the different types of PtP deals is a nonlinear function of the model parameters βm , such that interpretation of these parameters is not straightforward. For interpretation of the model, it is useful to consider the log-odds ratio of group m versus group l, defined as log P [yi = m|xi ] P [yi = l|xi ] = x′i (βm − βl ). (3) This shows that firms with a larger value for xi,j more likely belongs to group m than to group l if (βm,j − βl,j ) > 0, where xi,j indicates the j-th element of xi , and βm,j and βl,j are the corresponding coefficients. Note that this does not necessarily imply that the probability that firm i belongs to group m increases with xi,j , as the the odds ratios of group m versus the other categories also change. The net marginal effect of a change in xi,j on the group probability follows from the partial derivative 13 of P [yi = m|xi ] with respect to xi,j , which is given by ! M X ∂P [yi = m|xi ] = P [yi = m|xi ] βm,j − βl,j P [yi = l|xi ] . ∂xi,j l=1 (4) The sign of this derivative depends on the sign of the term between brackets, which may be positive or negative depending on the value of xi . Hence, the sign of the marginal effect of xi,j on P [yi = m|xi ] will not always correspond with the sign of the coefficient βm,j . Also note that the marginal effect depends on the values of the other explanatory variables in xi , denoted as xi,−j . In order to obtain a clear view on ∂P [y =m|x ] i i,j = the effect of the variable of interest xi,j one should therefore consider ∂xi,j R ∂P [yi =m|xi ] dxi,−j , integrating out the effects of these other explanatory variables. ∂xi xi,−j In practice this can be done by averaging (4) across all realizations of xi,−j in the sample for each value of xi,j . In the empirical analysis presented in the next section we follow a more direct approach by considering the group probabilities P [yi = m|xi,j ] themselves to gauge the effects of the different firm characteristics on the probabilities of the different types of PtP deals. We do average out the effects of other P explanatory variables by computing P [yi = m|xi,j ] = N1 N n=1 P [yn = m|xi,j , xn,−j ], where N is the sample size. An important assumption underlying the MNLR model in (1) is independence of irrelevant alternatives, meaning to say that the odds ratio of, for example, PE-backed and management-led PtP deals does not depend on the inclusion of the third group of PtP transactions, which can also be seen from (3). We examine the validity of this assumption by means of the specification test developed by Hausman and McFadden (1984). Our heterogeneity hypothesis of PE-backed and management-led PtP transactions implies that certain firm characteristics such as free cash flow and management ownership affect the relative probabilities of a firm belonging to the different groups. Put differently, in the MNLR model the coefficients βm,j should differ across groups m. For an individual variable, xi,j say, the null hypothesis of no heterogeneity across groups m and l can easily be tested by means of a likelihood ratio test of the restriction βm,j = βl,j . The same holds for a given sub-set of the explanatory variables included in the model. Testing whether there is no heterogeneity at all is slightly 14 more involved, and effectively boils down to testing whether two groups can be combined into one. This is done by means of the likelihood ratio test developed by Cramer and Ridder (1991). Finally, we should remark that the above likelihood ratio test statistics also enable us to assess in which respects the third group of PtP transactions is similar to the private equity backed and management sponsored deals. 4 Results The main contribution of this paper is to show that the population of the PtP firms is heterogeneous and that the reasons for going private are different for private equity backed deals versus management sponsored deals. To examine this hypothesis, we estimate multinomial logistic regressions with private equity backed, management sponsored and other PtP deals analyzed against the control firms that remained public. Table 3 reports the estimation results. To account for industry and time effects, all regressors are taken in deviation from industry median and annual median values. Our model treats the non-PtP control firms as the omitted category. Hence, Table 3 reports coefficients for private equity backed, management sponsored and other deals separately in subsequent columns. These coefficients show how the explanatory variables affect the probability of going private through the particular type of transaction relative to the probability of remaining public. The last three columns in Table 3 show p-values for a likelihood ratio test of equal parameters among the three types of PtP deals. Thus, these columns show significance of pair-wise coefficient differences among the going private types. Finally, the last two lines of Table 3 show p-values for the likelihood ratio test of Cramer and Ridder (1991) that all parameters except the intercept are equal for the corresponding two groups and the independence of irrelevant alternatives test, respectively. - insert Table 3 about here Overall, the results suggest that going private transactions are indeed heterogeneous. The no heterogeneity test of Cramer and Ridder (1991) suggests that all 15 three going private groups have different deal characteristics from the non-PtP firms as well as from each other. Moreover, the independence of irrelevant alternatives test reported in the last row indicates that the choice of the particular type of going private deal (whether the deal is indeed supported by a private equity house or is fully led by the management or is sponsored through another party) is fully independent. Thus, the decision to go private is made at the same time as the decision about the type of the deal. In other words, it is not the case that the firm decides about going private first and then looks for possible methods how to realize it. The independence of irrelevant alternatives test also shows that the multinomial logistic regression is the preferred estimation method and that this method fits the setting of going private decision better than a nested logit model, for example. 4.1 Undervaluation The results in Table 3 suggest that perceived undervaluation plays an important role in management sponsored deals, but less so in private equity backed deals. The coefficient for the market to book ratio is significantly negative for both types of PtP deals showing that both the private equity backed and management sponsored deals are on average undervalued relative to the firms that remain public. However, the management sponsored deals are also significantly more undervalued (at the five percent level) relative to the private equity backed deals. These results show that low levels of market to book ratio increase the probability of going private but do not necessarily support the link between market to book ratio and undervaluation. Therefore, we perform several sensitivity checks that in our view provide additional evidence that undervaluation is an important factor motivating (management sponsored) PtP deals. First, we account for the possibility that the low market-to-book ratio reflects low growth prospects or generally low performance of the PtP firms. Therefore, we include average sales growth over the last three years and return on assets as control variables in the regression in Table 3. The two variables are, however, not statistically significant. It seems that neither growth prospects nor profitability distinguish the going private firms from each other and from the firms that remained 16 public and suggests that market to book may indeed capture undervaluation of the firms. Second, we take advantage of the fact that takeover interest is often associated with undervalued firms. The positive and significant (at the one percent level) coefficients for rumours in Table 3 indicate that both PtP types experience relatively high takeover interest in the period before the deal compared to the control group of firms that remained publicly listed. Even though the two coefficients are not statistically different from each other, a closer analysis of the relationship between takeover interest and market to book ratio reveals interesting differences between the management sponsored versus private equity backed deals. The literature suggests that undervaluation of buyout firms increases chances of takeover bids from third parties (Lehn and Poulsen, 1989) and then this jointly motivates management to take their firms private. Our data confirm this conjecture for the management sponsored deals: The frequency of rumours conditional on market to book being below the sample median is 39%, 48%, and 23% for the management sponsored deals, private equity backed deals and non-PtP firms, respectively, whereas the frequency for firms with market to book above the sample median is 0%, 39%, and 18%, respectively. So, the management sponsored PtP deals experience a very strong negative correlation between market to book and takeover rumours. In other words, the management sponsored deals are attractive for third parties only in case they have relatively low market to book ratio and we believe this result supports the conjecture that undervaluation together with takeover threat play a very important role in motivating the management sponsored deals. This effect is not present for the private equity backed deals which then indicates that undervaluation does not play such a primary role for the latter type. To confirm this conjecture in a regression setting, we augment our basic regression model from Table 3 with an interaction term between market to book and rumours. Results are reported in Table 4 and support a strong complementary effect between market to book and rumours for the management sponsored deals: The coefficient for the interaction term is, as expected, negative and significant and, moreover, 17 the rumour coefficient becomes statistically insignificant. The private equity backed deals are not affected in the same way. In short, our data show that high takeover interest strengthens the effect of low market to book ratio on the probability of management sponsored PtP deals and supports our hypothesis on undervaluation. - insert Table 4 about here Third, insider trading patterns in firms in our sample reported in Table 4 provide further evidence supporting the view that our results on market to book ratio pick up the effect of private information. If undervaluation is indeed one of the reasons for going private, we could expect that managers’ trading in advance of the event may partially reveal the importance of that information. In fact, Harlow and Howe (1993) document significant increase in trading by insiders prior to the announcement of US management-led buyouts over the period from 1980 to 1989. They show, however, that this abnormal pattern arises not from increases in purchases but from abnormally low levels of stock sales. Harlow and Howe (1993) argue that this passive insider trading strategy is preferred by managers as it reduces their liability risk. In line with this existing evidence, our management sponsored deals should experience abnormally low insider sales relative to the private equity backed deals and non-PtP firms. In order to show this, Table 4 includes two dummy variables that reflect the insider purchase and sale patterns of executive directors of firms in our sample. In particular, the executive director purchase (sales) dummy is set to one in case an executive director purchased (sold) some shares of his/her own firm in the calendar year prior to the announcement and set to zero otherwise. Our results confirm that managers of the management sponsored deals tend to sell their shares significantly less often than their counterparts in non-PtP firms and private equity backed deals. We do not see any significant differences for the purchase patterns. Thus, our results are in line with Harlow and Howe (1993) and support our conclusion that firm undervaluation is more important in motivating management sponsored deals versus private equity backed deals. 18 Figures 1a to 1d show the probability that a firm belongs to a particular type of going private transactions as a function of market-to-book, rumours, sales growth, and ROA, respectively. These graphs provide additional intuition for the results as the coefficient estimates in Tables 3 and 4 indicate only the sign but not the functional form of the relation. It is important to note that the variable on the x-axis is measured as deviation from the year and industry specific medians. In addition, the effect of the remaining explanatory variables from the regression is averaged out. Figure 1a supports our result from Table 3 that undervaluation tends to be associated with the management sponsored deals and to a lesser extent with the private equity backed deals. In fact, Figure 1a shows that the probability of a management sponsored deal sharply increases as market to book falls whereas this is not the case for the private equity backed deals. In Figure 1b we see that the probability of both private equity backed and management sponsored deals increases with the number of takeover rumours but the two functions are quite close to each other. In summary, our results suggest that market undervaluation plays an important role for the management sponsored PtP transactions that have significantly lower market-to-book ratio relative to the control firms that remained publicly listed. In contrast, for private equity investors, undervaluation of their target is not so important. On average, private equity targets are significantly less undervalued than the management sponsored deals. 4.2 Visibility The results in Table 3 also support our second conjecture that low financial visibility may increase chances of management sponsored deals whereas it is not important for private equity backed deals. The most widely accepted empirical measure of firm visibility is the number of analysts following a firm (O’Brien and Bhushan, 1990). Analyst reports are documented to be the primary source of information for most buy-side investors (Baker et al., 2002). In Table 3, the coefficient for the number of analysts following a firm is negative and significant at the ten percent level for the management sponsored deals whereas it is positive but not significant for the private 19 equity backed deals. Importantly, the two coefficients are significantly different at the ten percent level indicating that management sponsored deals suffer significantly lower financial visibility relative to private equity backed deals. We also employ an alternative measure of investor interest that is available for all firms in our sample and is based on frequency of price changes. It is intuitive to expect that stocks with low investor interest would be traded relatively infrequently. Low trading frequency or days with no trading are then associated with no price movements and zero daily returns. In contrast, stocks that attract investor interest are traded relatively frequently and experience frequent (small) price changes that reflect constant price discovery. So, our measure of thin trading measures the frequency of zero daily returns in the previous calendar year and high levels indicate low trading frequency, investor interest and financial visibility (Fidrmuc et al., 2006). The results in Table 3 show that thin trading (high fraction of zero returns) is associated with higher probability of a management sponsored deal relative to both the non-PtP control firms as well as the private equity backed deals (both statistically significant at the one percent level), which confirms our financial visibility hypothesis. Firm size may also be closely associated with financial visibility of a firm (O’Brien and Bhushan, 1990). The coefficient estimates for size (log of total book value of assets), however, do not support this claim. In fact, the coefficient for management sponsored deals is positive and significant indicating that management sponsored deals on average are larger. Inspecting the correlation matrix, however, we find high positive correlation between size and thin trading. This means that inclusion of the thin trading variable in the regression strongly affects the coefficients for size. As both variables are important and their correlation does not affect other coefficients, we opt to include both total assets and thin trading in our model. However, the coefficients for size should be interpreted with caution as excluding the thin trading variable from the regression results in size being negative and statistically significant (at the one percent level) for the management sponsored deals and not significant for the private equity backed deals. 20 Another important issue is that our results for financial visibility may be driven by size. Put differently, it may be the case that our PtP firms, especially the management sponsored deals, are relatively small and then of course, they are thinly traded and not followed intensively by analysts. To make a stronger case for our visibility hypothesis, we would like to see that the PtP firms are distributed relatively evenly across the size spectrum of our sample and show lower levels of analyst coverage and higher levels of thin trading across all sizes. In order to check this, Table 5 shows mean values of our analyst coverage and thin trading measures as well as frequencies of private equity backed and management sponsored deals across size deciles (measured by total assets). Table 5 confirms that analyst coverage and thin trading are indeed positively correlated with size. However, it also shows that even though the going private firms are significantly underrepresented among the smallest and largest firms, PtP firms are relatively evenly spread across the remaining 8 middle size deciles. Thus, this indicates that the association between financial visibility and probability of going private is not due to the size effect. - insert Tables 5 and 6 about here To push this argument further, Table 6 reports the same statistics by size deciles separately for the non-PtP firms, private equity backed firms and management sponsored firms, respectively. Panel A, reporting the means for the non-PtP firms, confirms the overall trend that analyst coverage is increasing and thin trading falling with size. The same pattern is reflected in Panel B for the private equity backed firms. Overall, the private equity backed deals seem to be slightly less frequently traded but equally monitored by analysts relative to the non-PtP firms across all size deciles. In contrast, Panel C shows sharply lower analyst coverage and thinner trading for management sponsored deals relative to the non-PtP firms across all size deciles. Thus, this shows that the management sponsored deals suffer lower market visibility relative to both private equity backed deals as well as the non-PtP deals. Moreover, this effect is clearly present across all size deciles and, thus, is not driven by size. 21 Another closely related argument is that the going private firms might be more likely to be listed on the Alternative Investment Market (AIM) with lower listing requirements which in turn would drive the visibility result. The last column in Tables 5 and 6 reports AIM listing frequency among our firms and does not detect any significant trend. Also, in an unreported regression, we include an AIM dummy as an additional regressor. As the coefficients are not significant and the other results remain unaffected we conclude that AIM listing does not drive our results. Figures 1e and 1f provide visual intuition and further support for our findings. They show clearly that the probability of management sponsored deals is sharply increasing with low analyst coverage and thin trading. In contrast, this is not the case at all for the private equity backed firms. Overall, our results support the hypothesis that the going private firms are heterogeneous with respect to financial visibility. Management sponsored deals seem to suffer both low analyst coverage and infrequent trading and therefore have less reasons to remain publicly listed whereas this is not the case for the private equity backed deals. 4.3 Free cash flows Our third hypothesis conjectures that more cash rich firms are more likely to go private via a management sponsored deal whereas low cash levels increase the probability of a private equity backed deal. The coefficients for our cash variable in Table 3 support the hypothesis as they show that, relative to the non-PtP control firms, the management sponsored deals and the private equity backed deals have significantly higher and lower cash levels, respectively. The coefficients are significant at the ten and one percent level, respectively and are statistically different from each other at the one percent level. Still, it is important to control for sales growth as Jensen (1986) suggests that the agency problems of free cash flow concern mature firms with low growth prospects. The sales growth variable, however, is not significant implying that growth opportunities do not affect the probability of going private. Thus, controlling for growth opportunities, our results suggest a sharp difference in the effect of cash levels: management sponsored deals seem to be cash rich while private equity backed deals suffer very low cash levels. 22 An alternative interpretation of the low cash levels of private equity backed deals might be firm insolvency and inability to pay interest payments. To account for this possibility, we check average interest coverage across deciles of cash levels of the private equity backed firms. This exercise, however, shows that interest coverage is not related to cash level of the private equity backed deals. Moreover, including interest coverage in the regression does not result in a significant coefficient for the private equity backed deals nor does this affect the cash coefficient.5 Therefore, we conclude that this alternative explanation is not plausible for our setting. As a sensitivity check for our measure of managerial opportunism, we also estimate excess cash recently proposed in the literature on determinants of cash reserves level (Opler et al., 1999 and Dittmar and Mahrt-Smith, 2007). In line with this methodology, we estimate a cash regression that should determine normal cash levels used in companies to cover their liquidity needs.6 Residuals of this regression then measure cash reserves held in excess of those needed for operations and investments. These resources are most at risk of being wasted at the managers’ discretion (Dittmar and Mahrt-Smith, 2007). Note also that excess cash satisfies the stock requirement of DeAngelo and DeAngelo (2006) as discussed in section 3.2 above and therefore is a very good candidate for the proxy that should reflect managerial opportunism in cash rich firms. In Table 4, we partition the cash variable from Table 3 into two separate variables: normal cash and excess cash representing the fitted values and residuals from the cash regression, repectively. The results are equally strong now despite fewer observations due to data availability for the cash regression. They show that high excess cash levels increase the probability of management sponsored deals whereas low excess cash levels are associated with private equity backed deals. The regression in Table 4 includes also free cash flow and shows 5 All results are available upon request. Following Opler et al. (1999) and Dittmar and Mahrt-Smith (2007) we regress the natural logarithm of cash over net assets (total assets minus cash and marketable securities) on the natural logarithm of net assets, market to book adjusted for net assets, net working capital over net assets, capital expenditures over net assets, R&D over net assets, free cash flow over net assets, leverage and a dividend dummy. All variables are industry and time adjusted. Due to missing data, we are able to obtain only 1,437 observations for excess cash compared to 1,579 observations in our full sample. 6 23 that free cash flow do not affect the decision to go private. Finally, we include the payout ratio as an additional explanatory variable because firm dividend policy is closely related to the free cash flow hypothesis (Jensen, 1986): high dividend payout may mitigate the agency problems associated with free cash flow. DeAngelo and DeAngelo (2006) provide a different argument. They combine capital structure decisions with payout policy and constraints on liquid assets (cash) and claim that firms can develop three potential sources of future financial flexibility: cash accumulation, preservation of debt capacity and reputation for stable and substantial equity payouts. Cash accumulation as argued above increases managerial opportunism. High leverage reduces the agency costs but it utilizes debt capacity and therefore also financial flexibility. High ongoing equity payouts control agency costs without high leverage and thus preserve the firm’s option to borrow, and they also increase its future equity issuance capability. Therefore, it is important to control for payout as well as leverage when analyzing liquidity position of firms. Table 3 shows that the two payout coefficients are positive but only the coefficient for the private equity backed deals is significant (at the ten percent level). The coefficients for leverage are of opposite signs – private equity backed deals are less leveraged and management sponsored deals are more leveraged relative to the non-PtP firms – but neither of the coefficients is statistically significant at a conventional level. However, results in Table 4 are stronger: private equity backed firms pay significantly more dividends relative to the non-PtP firms and at the same time have lower leverage relative to both non-PtP firms and management sponsored deals (all at the five percent level). This suggests that private equity deals pay high dividends that reduce managerial opportunism of excess cash and keep high reputation to equity holders while, at the same time, preserve firm future borrowing potential. Clearly, private equity backed deals do not seem to suffer from agency problems and managerial opportunism. If anything, private equity backed going private transactions experience shortage of cash. Management sponsored deals, in contrast, enjoy high excess cash levels while at the same time enjoying relatively common payout 24 and leverage. This indicates that management sponsored deals may have problems with managerial opportunism. However, alternative and perhaps more plausible explanation for the high excess cash levels is that managers build up financial slack to finance the deal. Finally, we turn to the functional form of the probability functions shown in Figures 2a to 2c. Figure 2a shows that as the cash levels increase, the probability of a private equity backed deal decreases whereas the probability of a management sponsored deal increases, showing a contrasting characteristic of the private equity versus management sponsored deals. At the same time, the payout ratio in Figure 2b has a more dramatic effect on the probability of a private equity backed deal relative to a management sponsored deal. Hence, the results suggest that the management sponsored deals are more likely in firms with higher cash levels that may suffer the agency problems associated with excess cash. Alternatively, availability of high cash levels may simply make a leveraged buyout more feasible. In contrast, private equity backed deals are associated with negative excess cash levels, high dividend payments and low leverage. 4.4 Ownership structure Our final hypothesis highlights the heterogeneity in pre-transaction ownership and proposes that high executive ownership may increase chances of a management sponsored deal whereas high ownership by financial institutions increases chances of a private equity backed deal. Table 3 shows that the coefficient for executive ownership in the management sponsored deals is indeed positive and significant at the one percent level indicating that high executive ownership increases the probability of a management sponsored transaction relative to the firm staying public. However, executive ownership also increases the probability of a private equity backed deal. The corresponding coefficient is positive and significant at the five percent level. This supports the view that private equity investors look for support from management in their deals and choose firms with relatively high managerial ownership. Even though the MS coefficient is slightly larger, the difference between the two coefficients is not statistically significant. So, higher executive ownership increases the chances of both 25 private equity backed as well as management sponsored deals. In contrast, we find significant differences with respect to ownership by financial institutions, confirming the second part of our hypothesis. High ownership by financial institutions increases the probability of a private equity deal relative to both non-PtP firms as well as management sponsored deals (both statistically significant at the one percent level). These results are visualized in Figures 2c and 2d. In particular, the probability of management sponsored as well as private equity backed deals increase with executive ownership. However, only the probability of private equity backed deals increases with ownership by financial institutions. We also check for ownership concentration measured by the Herfindahl index with the expectation that the management sponsored deals have higher concentration of ownership by the management as other blockholders in these deals are relatively small. The results suggest that ownership concentration matters: it is significantly higher for the management sponsored transactions and lower for the private equity backed deals.7 In summary, our heterogeneity in ownership hypothesis is partially supported. Our results suggest that a management sponsored deal is more likely when the managers have higher control and concentration of ownership. At the same time, however, also private equity backed deals are more likely in firms with high managerial ownership suggesting cooperation between private equity investors and managers in the deals. The heterogeneity in pre-transaction ownership structure stems mainly from the differences in ownership by financial institutions. Willingness of the institutional investors to accept a deal proposed by a private equity party seems to increase the success of the transaction and thus motivates private equity investors to proceed with the deal in the first place. At the same time, very low ownership by financial institutions in the management sponsored deals may also reflect low investor interest for these deals that was discussed in section 4.2 above. In addition to size, our model includes two other control variables: tax and standard deviation of returns. The argument for taxes is that highly leveraged 7 All results are available upon request. 26 buyout transactions are associated with positive interest tax shield that may further increase incentives for going private. Our results in Table 3 suggest that taxes increase the odds of going private for the management sponsored deals but this is not supported in Table 4. The standard deviation of returns seems to be associated with a higher probability of a private equity backed deal (significant at the five percent level). This confirms the Gompers and Lerner (2001) suggestion that targets of private equity deals are associated with higher uncertainty and riskiness. 5 Concluding remarks This paper proposes that the recent increase of private equity investors’ involvement in going private transactions may affect sources of value creation and reasons explaining why firms decide to go private. Our analysis shows that the probability whether a deal is backed by private equity investment or is purely managed by insiders of the firm depends on different firm characteristics. Drawing upon several theoretical arguments (including Jensen’s free cash flow hypothesis, ownership structure, and the framework of costs and benefits of being publicly listed versus privately owned commonly applied in the IPO literature) we derive four testable hypotheses explaining reasons for management sponsored PtP deals: (i) undervaluation, (ii) financial visibility, (iii) free cash flow, and (iv) pre-transaction ownership structure. At the same time, we propose that private equity backed deals do not share the same characteristics as they are usually backed by strategic reasons and are not able to raise funds via traditional market sources. Therefore, pooling all PtP firms together may lead to weak estimation results and fail to detect the important determinants motivating management sponsored as well as private equity backed deals. In summary, our empirical results for the UK provide convincing evidence that the population of going private firms is indeed heterogeneous. We show that private equity backed and management sponsored deals have different reasons for their decision to take a firm from the stock market. Firms involved in management sponsored deals are significantly undervalued, not followed by analysts, have relatively high cash levels, high executive ownership, and ownership concentration. The private 27 equity backed deals, in contrast, have high executive ownership and high ownership by financial institutions but have lower ownership concentration. These firms have shortage of cash, low debt levels, and pay high dividends. Thus, our results suggest that the management sponsored deals fit the characteristics of the Jensen’s cash rich firms with strong management that are relatively thinly traded in the stock market, not followed by analysts and are significantly undervalued. This suggests that the benefits of remaining publicly listed fall short of the costs and the firms are more likely to go private. In contrast, benefits of stock market listing seem to be larger for the private equity backed deals as they are more actively traded, followed by analysts and not so much undervalued. However, they seem to be short of cash. Private equity backing may provide the necessary financing and extra know-how for their strategic restructuring. 28 References Allen, F., and D.

The model is estimated using 212 observations for UK PtP deals over the period 1997-2003. All regressors are industry and time adjusted as they enter the multinomial logit model as deviations from the industry and year median. The numbers of observations in the PtP groups are 90 for PE-backed deals, 69 for MS-deals, and 53 for other deals. The non-PtP group consists of 1400 observations. Standard errors are given in parentheses, with ∗∗∗ , ∗∗ , and ∗ indicating significance at the 1%, 5% and 10% level, respectively. The final three columns show p-values for the LR test of equal parameters across two sub-groups of PtP deals. The line “No heterogeneity test” reports p-values for the LR test of Cramer and Ridder (1991) that all parameters except the intercepts are equal for two groups. The first three numbers in this line compare the non-PtP group with one of the PtP groups. The line “IIA test” reports p-values for the Hausman and McFadden (1984) LR test for the validity of the independence of irrelevant alternatives (IIA) assumption, omitting the indicated group from the model.
