Cash holdings, corporate governance, and acquirer returns Seoungpil Ahn and Jaiho Chung May 11, 2012
Intuition Is competition good? Milton Friedman( ) would say yes and always yes Average parents in Korea would say NO for their kids Are the restrictions on shareholders’ rights bad? Yes, if entrench managers No, if talkative(?) shareholders impair timely decision makings Conditional on the current level of the restrictions and firm characteristics We examine this conditional effect of governance provisions
Governance Provisions and Firm Performance A milestone work by Gompers, Ishii, and Metrick (GIM, 2003) Governance Index based trading strategy yields abnormal returns during the 1990s. Short poorly governed firms (many anti-takeover provisions, ATPs) Long well governed firms (few ATPs) produced AR of 8.5% annually The abnormal return disappears in the later period after 2001 [Bebchuk, Cohen, Wang, 2012; Core, Guay, and Rusticus, 2006]
Does causality run from ATPs to firm performance? Spurious correlation ATPs may reflect risk that is not captured by expected return models [GIM, 2003; Core, Guay, and Rusticus, 2006] Endogeneity issues [Masulis et al., 2007; Danielson and Karpoff (1998) among others] Look-ahead adoption of ATPs before the impending events The influence of omitted factors [Core, Guay, and Rusticus, 2006] Poor past performance or other unobservable factors covary with ATPs Causal relation Market participants learn the performance difference between well governed firms and poorly governed firms [Bebchuk, Cohen, and Wang, 2012; Cremers and Nair, 2005]
Attention to corporate governance Attention to governance from the media, institutional investors, and academic researchers has exploded since early [Netter, Poulsen, and Stegemoller, 2009; Bebchuk, Cohen, and Wang, 2012]
Structural break of market learning Market participants become aware of the importance of corporate governance by the end of 2001 [Bebchuk, Cohen, and Wang, 2012] Learning hypothesis Anomaly in the pre-SOX period: ATPs indeed reduce firm value Market learning eliminates AR in the period (Post-SOX period)
A Caveat When market participants are aware of the detrimental impact of ATPs, how do ATPs survive under shareholders’ activism and the pressure from institutional investors and policy makers? G-Index includes 24 provisions BCF Index includes 6 most entrenching provisions Pre-SOX ( ) Post-SOX ( ) F[χ2]F[χ2] G-Index 9.29 [9.00] 9.29 [9.00] 0.00 [0.26] BCF 2.12 [2.00] 2.40 [2.00] *** [40.72] ***
Our study We re-examine bidder returns Weak shareholder protection: Lower bidder announcement returns in [Masulis et al., 2007] Focusing on the influence of omitted factors: If the market learning does not lead to the abolishment of ATPs, what are the exact channels through which the effect of ATPs disappear in the post-SOX period? The role of excess cash holdings The influence of external governance (EG) Public pension fund holdings (ownership by 19 largest pension funds) Industry competition (industry Net Profit Margin)
The interaction among governance indices, excess cash, and external governance mechanisms Excess cash holdings for poorly governed firms: Lower value of cash holdings Dissipate cash quickly in capital expenditures [Dittmar and Mahrt-Smith, 2007; Harford, Mansi, and Maxwell, 2008] For the relation between ATPs and bidder returns: No main effect [Masulis et al., 2007] Interaction effect? We examine the impact of ATPs on bidder returns when ATPs and excess cash interact
The strength of external governance mechanisms: Various governance mechanisms interact The effect of ATPs depends on: Product market competition [Giroud and Mueller, 2010] The presence of large institutional investors [Cremer and Nair, 2005] The effectiveness of CEO incentives depends on the strength of external governance [Kim and Lu, 2011] We expect that the impact of ATPs on bidder returns to depend on the strength of external governance (EG) forces. No main effect [ Masulis et al., 2007] Interaction effect?
Data Firms covered in Investor Responsibility Research Center (IRRC ) database For the period of 1995,1998,2000,2002, 2004, and 2006 volumes of IRRC. Interpolate the skipping years. Firms completed acquisitions from SDC M&A database Control less than 50% and then 100% after the transaction Deal value > $1m Stock price data available in CRSP
Final sample 3,340 acquisitions in the period by 1,217 unique firms 1,767 acquisitions in the pre-SOX period and 1,549 acquisitions in the post-SOX period. We also utilize panel data set for these firms conducted acquisition at least once during the sample period.
First look at the data All Period Pre-SOX ( ) Post-SOX ( ) F[χ2]F[χ2] G-Index 9.29 [9.00] 9.29 [9.00] 9.29 [9.00] 0.00 [0.26] BCF 2.25 [2.00] 2.12 [2.00] 2.40 [2.00] *** [40.72] *** CAR MM (-2, +2) *** [0.311] *** [0.169] *** [0.493] *** 7.35 *** [7.85] *** CAR MAR (-2, +2) *** [0.530] *** ** [0.225] ** *** [0.732] *** 7.97 *** [11.29] *** N3,3401,7671,549

Table 2. Descriptive Statistics
The relation between bidder return and the BCF-index CAR MM (-2,+2) = + 1 BCF Index + Controls + Learning hypothesis: Negative in the pre-SOX period Insignificant in the post-SOX period The influence of omitted factors: Negative in the presence excess cash and under weak EG Insignificant in the absence of excess cash and under strong EG Weak EG: pension ownership is below the sample median value Industry NPM is above the median value

Table 4 External governance, antitakeover provisions, and acquirer returns
Table 5 The interactive effect of antitakeover provisions and pension holdings, industry competition, and excess cash
Evidence so far: The adverse impact of anti-takeover provisions on bidder returns: In much narrowed context than previously thought Only for firms amassing excess cash and facing weak EG Not independent effect of ATPs Suggesting that ATPs are not necessarily value-destroying for all firms
Robustness Tests in Table 6 Include CEO incentives delta and vega Include board characteristics board size, % independent directors, CEO-chair duality Use CAR MAR (-2, +2) Alternative definition of EG block ownership, industry median sales expenses Alternative governance indices G-index and classified boards Sub-sample test for the pre- and post-SOX periods
Endogeneity Econometric approach: 3SLS where CAR, BCF, and MtoB are jointly determined Instrument variables approach Dynamic panel GMM [Wintoki, Linck, and Netter, 2011] Qualitative approach: Actions of pension funds in marginalizing the adverse impact of ATPs One possible channel: Pension funds exert pressure on firms to eliminate ATPs when they hurt shareholder wealth We thus test the probability of removal by strong EG

The role of active pension funds ATPs Firm Value (a) Market Learning Hypothesis(b) Our Evidence
Conclusion We identify the influence of omitted variables: The effect of ATPs interact with excess cash and EG ATPs alone are not necessarily value-destroying A decrease in excess cash and an increase of pension ownership in the post- SOX period Alternative explanation to market learning Better explanation than market learning Knowing the adverse impact of ATPs, market learning implies complete elimination of ATPs: Pervasiveness of ATPs for a majority of firms until recent years No evidence of price adjustment No direct link between market learning and the disappearance of the adverse impact Only partial elimination of ATPs by active pension funds Thereby, the wealth effect of ATPs is neutral
