Answer: d. trades as an ADR
Step-by-step explanation:
American Depository Receipts (ADR) allow for Americans to trade on foreign stock as if they were trading in American stocks. It works by a bank buying a lot of shares in the Japanese company for instance.
They will then reissue these stock as ADRs in the American stock exchanges and also value the ADR based on their valuation models to find out the ratio of ADR to share quantity. If the Japanese company is trading as an ADR. you will be able to invest in them from the United States.
