Dear Sirs

Invesco Finance PLC (the “Company”) and the registration statement on Form S-3 dated 8 October 2015 (the “Registration Statement”) with respect to the registration (the “Registration”) of securities of Invesco Ltd. or its subsidiaries to be filed with the Securities and Exchange Commission of the United States on 8 October 2015

1 We have acted as your English legal advisers in connection with the Registration and have taken instructions solely from you.

2 This opinion is limited to English law as applied by the English courts and in effect on the date of this opinion. It is given on the basis that it will be governed by and construed in accordance with English law.

3 For the purpose of this opinion we have examined the documents listed and, where appropriate, defined in the Schedule to this opinion.

4 Based on the documents referred to in paragraph 3 above and subject to the qualification in paragraph 5 below and to any matters not disclosed to us, we are of the opinion that the Company is a company incorporated in England under the Companies Act 2006 and is existing as a company with limited liability under the laws of England.

5 Our opinion that the Company is existing is based on the Search and the Telephone Enquiry. The Search did not reveal any order or resolution for the winding-up of the Company or any notice of appointment in respect of the Company of a liquidator, receiver, administrative receiver or administrator having been given. The Telephone Enquiry did not indicate any presentation of any winding-up petition or any other insolvency proceeding in respect of the Company. However, it should be noted that the Search and the Telephone Enquiry are not capable of revealing conclusively whether or not a winding-up petition or order has been presented or made, a receiver appointed, a company voluntary arrangement proposed or approved or any other insolvency proceeding commenced.

6 It should be understood that we have not been responsible for investigating or verifying the accuracy of the facts, including statements of foreign law, or the reasonableness of any statements of opinion, contained in the Registration Statement, or that no material facts have been omitted from it.

This communication is confidential and may be privileged or otherwise protected by work product immunity.
