Householding

To eliminate duplicate mailings and reduce expenses, the Portfolio may deliver a single copy of certain shareholder documents, such as the Portfolio’s summary prospectus/prospectus and annual and semi-annual reports, to related shareholders at the same address, even if accounts are registered in different names. This practice is known as “householding.” The Portfolio will not household personal information documents, such as account statements. If you do not want the mailings of these documents to be combined with those of other members of your household, please call the transfer agent at (888) 576-1167. We will begin sending individual copies of the shareholder documents to you within 30 days of receiving your request.
