HOUSEHOLDING INFORMATION

Unless we have received contrary instructions, we may send a single copy of this Proxy Statement to any household at which two or more
shareholders reside if we believe the shareholders are members of the same family. This process, known as “householding”, reduces the volume of duplicate information received at any one household and helps to reduce our expenses.
However, if as shareholders as of the Record Date, you and members of your family who reside at the same address prefer to receive multiple sets of our disclosure documents at the same address this year or in future years, you should follow the
instructions described below. Similarly, if you share an address with another shareholder and together both of you would like to receive only a single set of our disclosure documents, you should follow these instructions:
