The Long Run Abnormal Performance of UK Acquirers and the Free Cash Flow Hypothesis

Abstract:   Evidence from recent US and UK studies reveals a pattern of poor long run post acquisition performance by acquiring firms. One explanation, due to Jensen (1986) is that acquirers with an excess of free cash flow (FCF) will have a propensity to squander this on wasteful investments, including take‐overs. In this paper, using a dataset of UK take‐overs and proxies for free cash flow similar to those used by Lang, Stulz and Walking (1991) , we find no support for the FCF hypothesis and show that this conclusion is robust to the model of long run returns employed. Contrary to the free cash flow hypothesis there is evidence that acquirers with high free cash flow perform better than acquirers with low free cash flow. Although not consistent with the Jensen hypothesis, this evidence is compatible with the emerging UK evidence that shows cash flow‐to‐price measures are associated with market returns.     

基于自由现金流代理成本假说的投资行为研究

基于自由现金流代理成本假说，本文利用我国上市公司（A股）制造业1998-2003年数据对上市公司投资行为进行实证研究。研究结果表明，（1）经理持股比例越低，代理问题越严重，投资现金流相关性越高。（2）企业融资约束程度越轻，代理问题越严重，投资现金流相关性越高，经理越容易建造“企业帝国”。具体表现为：国家股比例越高，投资现金流相关性越高；净资产税后利润率越高，投资现金流相关性越高；企业规模越大，投资现金流相关性越高。建立有效的公司治理机制可以解决有关代理问题。     

Growth Capital‐Backed IPOs

Growth capital investing is the financing of growing businesses that are investing in tangible assets and the acquisition of other companies. Growth capital is common in retailing, restaurant chains, and health care management, and represents 12% of all venture capital (VC)‐backed initial public offerings (IPOs). Since 1980, investing in growth capital‐backed IPOs has produced mean three‐year style‐adjusted buy‐and‐hold returns of +25.2%, in contrast to style‐adjusted returns of approximately zero for other VC‐backed and buyout‐backed IPOs. One‐third of growth capital‐backed IPOs are rollups and these have produced much higher returns for investors than rollups without a financial sponsor.     

Stock‐Split Post‐Announcement Returns: Underreaction or Market Friction?

We explore the relationship between stock splits and subsequent long‐term returns during the period from 1950 to 2000. We find that, contrary to much previous research, firms do not exhibit positive long‐term post‐split returns. Instead, we find that significant positive returns after the announcement date do not persist after the actual date of the stock split. We also observe that abnormal returns are correlated with the price‐delay or market friction. We conclude that the stock‐split post‐announcement “drift” is only of short duration, and it is attributable to trading frictions rather than behavioral biases.     

Long‐term Performance of Greek IPOs

We analyse the long‐run performance of 254 Greek IPOs that were listed during the period 1994–2002, computing buy‐and‐hold abnormal returns (BHAR) and cumulative abnormal returns (CAR) over 36 months of secondary market performance. The empirical results differ from international evidence and reveal long‐term overperformance that continues for a substantial interval after listing. Measuring these returns in calendar time, we find statistical significance with several of the benchmarks employed. We also find that long‐term overperformance is a feature of the mass of IPOs conducted during a pronounced IPO wave. Cross‐sectional regressions of long‐run performance disclose several significant factors. The study demonstrates that although Greek IPOs overperform the market for a longer period, underperformance eventually emerges, in line with much international evidence. Our interpretation is that the persistence of overperformance over a significant interval is due to excessive supply of issues during the ‘hot IPO period’. Results associated with pricing during the ‘hot IPO period’ indicate positive short‐ (1‐year), medium‐ (2‐year) and negative long‐term (3‐year) performance.     

IPO Pricing,Block Sales,and Long‐Term Performance

Block sales following IPOs are related to the IPOs' value relative to an estimate of intrinsic value, opening‐trade return, and IPO size. Overvalued IPOs experience more block sales than undervalued IPOs. IPOs with high block sales outperform IPOs with low block sales from 20 days after IPO through lockup expiration; however, IPOs with high block sales underperform IPOs with low block sales from lockup expiration through the third year after the IPO. The results indicate that block traders are advantaged relative to other traders; whether the advantage is based on superior information or superior valuation capabilities is unknown.     

Is Investment‐Cash Flow Sensitivity Caused by Agency Costs or Asymmetric Information? Evidence from the UK

We investigate the investment‐cash flow sensitivity of a large sample of the UK listed firms and confirm that investment is strongly cash flow‐sensitive. Is this sensitivity a result of agency problems when managers with high discretion overinvest, or of asymmetric information when managers owning equity are underinvesting if the market (erroneously) demands too high a risk premium? We find that investment‐cash flow sensitivity results mainly from the agency costs of free cash flow. The magnitude of the relationship depends on insider ownership in a non‐monotonic way. Furthermore, we obtain that outside blockholders, such as financial institutions, the government, and industrial firms (only at high control levels), reduce the cash flow sensitivity of investment via effective monitoring. Finally, financial institutions appear to play a role in mitigating informational asymmetries between firms and capital markets. We corroborate our findings by performing additional tests based on the stochastic efficient frontier approach and power indices.
