This page details the work rebuilding Brander Egan (2007) - The Role of VCs in Acquisitions for our submission to the RCFS special issue and associated conference.

Submission Details

The Third Entrepreneurial Finance and Innovation Conference on June 10th-11th in Boston, MA, is supported by the Kauffman Foundation and the Society for financial studies. Conference papers will be considered for inclusion in a special issue of the Review of Corporate Finance Studies.

The conference details are here: http://sites.kauffman.org/efic/overview.cfm

The deadline for submission is March 7th, 2012, though earlier submission is encouraged. Authors will be notified if their paper has been selected by the end of April.

The program committee includes: Thomas Hellmann, Adam Jaffe, Bill Kerr, Josh Lerner, David Robinson, Morten Sorenson, Bob Strom, and others.

Rebuilding the Paper

The paper requires a complete rebuild of all the results, with the data updated to the end of 2011. We should also consider several extensions to the paper, detailed in a later section.

Main Data

Acquisitions (from SDC):

  • Events from 1980-2011 that meet the following criteria:
    • Acquirer is publicly traded on the AMEX, Nasdaq or NYSE
    • Target is privately-held prior to acquisition (note: new restriction - target was not an LBO)
    • Acquisition is for 100% of the firm
    • Acqisition is complete before end of January 2012

Subsequent restriction: Drop acquisitions where market value of assets is negative or very small compared with the TV.

Venture Capital (from VentureXpert):

  • Portfolio companies that received VC from 1975-2011. Must not be LBOs.
  • LBOs from 1975 to 2011 to ensure that they are not in the control group of privately-held non-VC backed firms)

Returns:

  • Stock returns for 1 year (250 Calendar days) for the acquirer, ending 30 days before the announcement. This will be the estimation window.
  • Market returns for the same period
  • Stock returns for 7 days beginning 3 days before the announcement and ending 3 days after

Note: an observation must have 50 days of continuous trading in the estimation window, and be traded in the event window, to be included.


Supplementary Data

To determine the information asymmetry ranking of sectors we will need (either for 1 year or across the entire year range):

CRSP:

  • idiosyncratic volatility of stock returns: requires returns and mkt returns
  • relative trading volume (???)
  • NAIC

COMPUSTAT:

  • intangible assets
  • total assets
  • Tobin's Q: Market value/book value of assets
  • NAIC

Raw Variables

From SDC:

  • Transaction Value
  • Payment Method
  • Acquisition announcement date
  • Acquisition announcement year
  • Total assets of acquirer (if available)
  • Payment method (cash/stock/mix)
  • CUSIP (for join to COMPUSTAT)
  • Target NAIC
  • Acquirer NAIC (if available)
  • Age (of target)
  • Sales (of target)
  • Leverage (of target)
  • Intangible Assets (of target)

From COMPUSTAT:

  • Total Assets
  • Market Value (SHROUT*Price at announcement)
  • Sales
  • Leverage variables
  • Intangible Assets

From VentureExpert:

  • VC (binary variable)

Calculated variables

Returns:

  • [math] AR_i = R_i- (\hat{\alpha_i} + \hat{\beta_i}R_m [/math]
  • [math] AR^S_i = R_i - R_m [/math]
  • Let [math]\epsilon[/math] be the residual from the mkt model regression. Then calc: [math]\sigma_{\epsilon}={( \mathbb{E}(\epsilon - \mathbb{E} \epsilon))}^{\frac{1}{2}}[/math]
  • RMSE of the Mkt Model: [math]RMSE={( \mathbb{E}(X- \mathbb{E} X))}^{\frac{1}{2}}[/math] - this is in the ereturn list in STATA.

SDC:

  • No of past acquisitions for each acquirer
    • VC
    • Non-VC


Dataset level calculations:

  • Boom: [math]1990\le year \le 1999[/math]
  • Leverage: <math>\frac{Op.\;Income}{Net\;Income}
  • IT/BT/HT and 1dg-NAIC, 2dg-NAIC, other classification. Applied to targets and acquirers.
