PRIVACY NOTICE

The Fund collects only relevant information about you that the law allows or requires it to have in order to conduct its business and properly service you. The Fund collects financial and personal information about you ("Personal Information") directly (e.g., information on account applications and other forms, such as your name, address, and social security number, and information provided to access account information or conduct account transactions online, such as password, account number, e-mail address, and alternate telephone number), and indirectly (e.g., information about your transactions with us, such as transaction amounts, account balance and account holdings).

The Fund does not disclose any non-public personal information about its shareholders or former shareholders other than for everyday business purposes such as to process a transaction, service an account, respond to court orders and legal investigations or as otherwise permitted by law. Third parties that may receive this information include companies that provide transfer agency, technology and administrative services to the Fund, as well as the Fund's investment adviser who is an affiliate of the Fund. If you maintain a retirement/educational custodial account directly with the Fund, we may also disclose your Personal Information to the custodian for that account for shareholder servicing purposes. The Fund limits access to your Personal Information provided to unaffiliated third parties to information necessary to carry out their assigned responsibilities to the Fund. All shareholder records will be disposed of in accordance with applicable law. The Fund maintains physical, electronic and procedural safeguards to protect your Personal Information and requires its third-party service providers with access to such information to treat your Personal Information with the same high degree of confidentiality.

In the event that you hold shares of the Fund through a financial intermediary, including, but not limited to, a broker-dealer, bank, credit union or trust company, the privacy policy of your financial intermediary governs how your non-public personal information is shared with unaffiliated third parties.

For more information, please contact the Fund at 855-ATACFUND (855) -282-2386.

Please retain this Supplement for future reference.
