Description:

efx refers to Electronic Funds Xchange Inc., though it's important to note that the ticker "EFX" is more commonly associated with Equifax Inc., a consumer credit reporting agency listed on the New York Stock Exchange. Since there isn't a publicly traded company under the exact ticker "EFX" matching the description as Electronic Funds Xchange Inc., the correct and relevant company for the ticker EFX is Equifax Inc. Equifax provides consumer and business credit reports, identity verification services, and employment background checks. Given the instruction to return 'none' if no specific information is available for the given ticker, the appropriate response here is none.
