AstraZeneca completed a series of transactions to “harmonize” its share structure. One part of this process was to become listed on the NYSE with the ticker symbol AZN and cancel its American Depository Receipts (ADRs). Holders of the ADRs received the number of ordinary shares each ADR represented. In this case, each ADR was equivalent to 0.5 ordinary shares. Prior to this reorganization the ordinary shares were listed on the London and Stockholm stock exchanges. AstraZeneca is incorporated in the United Kingdom.

AstraZeneca states in its information to shareholders the exchange will qualify as a non-taxable event for US shareholders. We will assume the IRS does not dispute this opinion. The US tax consequences of the exchange reported in the circular to shareholders match the consequences of a stock split or merger. Since the ticker symbols of the ADRs and the new NYSE listed ordinary shares are the same, a stock split fits a bit better.

NOTE: The company stated they satisfy the conditions necessary to make this transaction non-taxable and may get legal advice that the transaction qualifies for non-taxable treatment. However, there is the possibility the IRS will disagree with their characterization. These instructions assume the company succeeds in its efforts. New instructions will be written, if and when it becomes known the exchange should be treated as a taxable event.
