(2) Beneficial ownership is calculated in accordance with Rule 13d-3 under the Act, whereby the reporting person is considered to beneficially own shares of Class A common stock of the Issuer by virtue of the ability, generally, to exchange Class A common partnership units of Artisan Partners Holdings LP (“APH”) for shares of Class A common stock of the Issuer on a one-for-one basis. In accordance with Rule 13d-3, in determining the percentage ownership, only those shares issuable to the reporting person upon an exchange of partnership units are considered to be outstanding, in addition to the already outstanding shares of Class A common stock. As a result, the beneficial ownership percentage does not reflect the reporting person’s actual voting or economic interest in the Issuer.
