, 21:21, 22 February 2012→Retrieving CUSIPS
Acquiror and Target names were keyed into unique names. The first acquisition of several was taken. 33 records had multiple entries, the correct one of which could not be determined. These were discarded.
===Retrieving CUSIPSCUSIPs===
The acquisitions data lists 6 digit CUSIPSCUSIPs, we need the 'correct' (the right issue for the right period) 8 or 9 digit CUSIP with which to search CRSP and COMPUSTAT. A full list of all CUSIPs was retrieved from COMPUSTAT for the period Jan 1978- Jan 2012 using the annual data.
