COST — Costco Wholesale Corp.

Core business is permissible, but alcohol sales are a minor part of revenue.

Why?

Costco's core warehouse retail business is permissible, but like many large retailers it sells alcoholic beverages as part of its merchandise mix. Screening providers differ on how to treat retailers with a small, non-primary revenue stream from impermissible products.

How this was screened

Primary basis: Financial-ratio screen.
