Dear Client,

Proxy statements were recently mailed for several Invesco Funds as part of a plan to reorganize Invesco’s U.S. mutual fund lineup. Invesco believes this change will enhance their offerings and better enable Invesco to deliver strong, consistent investment results over the long term.

I would like to encourage you to vote your proxy. You should have received a proxy card in the mail which you can complete, sign and return in the postage-paid envelope provided in the shareholder mailing. Alternatively, you can also vote online, by phone or in person. Please click here for more information on how to vote.

Thank you for your attention to this important matter.

Best regards,

Financial Advisor
