Basic outline is as follows:

*Imported COMPUSTAT Data

**Built composite primary key from unique gvkeys ~~cross~~cartesian-producted with years 1970 to 2015 (all other datasets will be joined onto this)

**Stripped out list of unique company names from COMPUSTAT data

**Used matcher to construct standardized company names, with lookup table to original names

**Sheet 3 contains COMPUSTAT output (unused)

**Sheet 4 contains private-to-private LBOs

*~~Use~~ Used SDC data to flag LBO events for COMPUSTAT data

**Joined sheets 1 and 2 to link gvkey to each LBO deal

**Joined resulting table to composite key to flag for LBO occurrences in given year-gvkey combination

**Note: this leaves many LBOs unmatched. Applying name-based matching to include more (esp. all private-to-private)
