If a partnership (including an entity or arrangement treated as a partnership for U.S.
federal income tax purposes) is a beneficial owner of depositary shares, the tax treatment of a partner in the partnership will generally depend upon the status of the partner and the activities of the partnership. A beneficial owner that is a
partnership and partners in such a partnership should consult their tax advisors about the U.S. federal income tax consequences of the ownership and disposition of the depositary shares.

This summary is for general information only and is not, and should not be interpreted to be, tax advice to any prospective holder of the depositary shares. Each potential investor should consult with his, her or its own tax advisor as to the U.S. federal, state, local, foreign and any other tax consequences of the ownership and disposition of the depositary shares in their particular circumstances.
