 shares for me at the American Water special meeting?                   |

| A: | No. If your shares are held in “street name” in a stock brokerage account or by an intermediary,                                                                                                                                              
 you must provide the record holder of your shares with instructions on how to vote your shares. If you do not provide instruction to the record holder, your shares will not be voted. Please follow the voting instructions provided by your 
 intermediary.                                                                                                                                                                                                                                 |

Applicable stock exchange rules permit intermediaries to vote their customers’ stock held in “street name” on routine matters when the intermediaries have not received voting instructions from their customers. Those rules do not, however, allow intermediaries to vote their customers’ stock held in “street name” on non-routine matters unless they have received voting instructions from their customers. In such cases, the uninstructed shares for which the intermediary is unable to vote are called “broker non-votes.”It is expected that all proposals to be voted on at the American Water special meeting will be non-routinematters on which intermediaries are not allowed to vote unless they have received voting instructions from their customers. Please note that you may not vote shares held in “street name” by returning a proxy card, or by returning a voting instruction form directly to American Water. Your intermediary is obligated to provide you with a voting instruction form for you to instruct the record holder on how to vote your shares.
