What is the crosswalk to GVKey in the output of the Risk Tool?

We offer a crosswalk to Compustat's GVKey as a convenience for our users.

While we have successfully used the crosswalk in our own academic work, it is offered as is and we are unable to provide support or guarantee its accuracy. If you find any errors, please let us know at [email protected].

The crosswalk is created by iteratively merging on CIK, ISIN, Ticker, and company name (exact and fuzzy match).
