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.

- [math] AR^S_i = R_i - R_m [/math]
