 granted as discussed below. Related person transactions are non-exempttransactions, relationships or arrangements in excess of $120,000 in which American Water or any subsidiary was or is to be a participant and a related person had or will have a direct or indirect material interest. For purposes of this policy, a “related person” is:

| · |     | an executive officer or director of the Company; |

| · |     | a beneficial owner of more than five percent of our common stock; or |

| · |     | an immediate family member (as defined by the policy) of any of the foregoing. |

Approval of a related person transaction may only be granted in writing in advance by the disinterested members of either the Board or the Audit, Finance and

Risk Committee. Before any related person transaction is approved, the following factors, among others, are to be considered:

| · |     | the purpose, and the potential benefits to American Water, of the transaction; |

| · |     | the related person’s interest in the transaction; |

| · |     | the dollar value of the transaction or the related person’s interest in the transaction without regard to the amount of any profit or loss; |

| · |     | whether the transaction is to be undertaken in the ordinary course of business of American Water; and |

| · |     | whether the transaction is on terms more favorable to American Water than a transaction with an unrelated third party. |

Approval of a related person transaction under the policy will be granted only if it is determined that, under all of the circumstances, the transaction is in the best interests of American Water and only so long as those interests outweigh any negative effects that may arise from permitting the transaction to occur.
