Hi everyone,

I would like to add merge Compustat data with the Boardex data I currently have; however, to do so I would need the gvkeys of the companies. Currently I only have permco and CompanyID codes. Would any of you know how I could for instance use a permco code to find a gvkey - is there a matching table or a search engine that you would know of?

Thanks a bunch!

Aurèle

hi Aurèle,

The ccm-linktable can be used to link permno/permco with gvkey: https://wrds-web.wharton.upenn.edu/wrds/tools/variable.cfm?library_id=137&file_id=66977

Would that work for you?

Best,
