Item 29. Persons Controlled By or Under Common Control with Registrant

The Adviser is an indirect wholly-owned subsidiary of Mutual of America Life Insurance Company (“Mutual of America”). Mutual of America is a New York mutual life insurance company, and as such no person has the direct or indirect power to control Mutual of America except by virtue of a person’s capacity as a director or executive officer. Each holder of an in-force insurance policy or annuity contract issued by Mutual of America has the right to vote for the election of directors of Mutual of America at annual elections and upon other corporate matters where policyholders’ votes are taken. Mutual of America’s ownership of its subsidiaries is as follows:

Mutual of America, a New York mutual insurance company, wholly owns

• Mutual of America Holding Company LLC, a Delaware limited liability company, and

• Mutual of America Foundation, a New York not-for-profit corporation.

Mutual of America Holding Company LLC wholly owns

• Mutual of America Securities LLC, a Delaware limited liability company,

• Mutual of America Capital Management LLC (the “Adviser”), a Delaware limited liability company, and

• 320 Park Analytics LLC, a Delaware limited liability company.

Mutual of America, through its separate accounts, owns substantially all of the shares of Mutual of America Variable Insurance Portfolio, a Maryland corporation registered under the 1940 Act as a management investment company whose shares are offered only to those separate accounts for funding variable life insurance and variable annuity products.

Mutual of America currently owns a significant portion, but less than 50%, of the outstanding shares of Mutual of America Institutional Funds, Inc., a Maryland corporation registered under the 1940 Act as a management investment company whose shares are publicly offered to institutional investors.

Mutual of America currently owns a significant amount of the Registrant’s outstanding shares.

Item 30. Indemnification

Articles of Incorporation of the Investment Company. The Articles of Incorporation of the Investment Company provide in substance that no director or officer of the Investment Company shall be liable to the Investment Company or its shareholders for money damages, unless the director or officer is subject to liability by reason of willful misfeasance, bad faith, gross negligence or reckless disregard of duties in the conduct of his or her office.

By-Laws of the Investment Company. The By-Laws of the Investment Company provide for the indemnification of present and former officers and directors of the Investment Company against liability by reason of service to the Investment Company, unless the officer or director is subject to liability by reason of willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of his or her office (Disabling Conduct). No indemnification shall be made to an officer or director unless there has been a final adjudication on the merits, a dismissal of a proceeding for insufficiency of evidence of Disabling Conduct, or a reasonable determination has been made that no Disabling Conduct occurred. The Investment Company may advance payment of expenses only if the officer or director to be indemnified undertakes to repay the advance unless indemnification is made and if one of the following applies: the officer or director provides a security for his or her undertaking, the Investment Company is insured against losses from any lawful advances, or a reasonable determination has been made that there is reason to believe the officer or director ultimately will be entitled to indemnification.

Insurance. Coverage for officers, directors and managers of the Adviser, Distributor and the Fund is provided under an Investment Management insurance policy issued by Chartis, with excess coverage by Chubb, CNA, The Hartford, and Travelers, to Mutual of America Life Insurance Company et al. The aggregate limit of liability under these policies is $35 million, with a $1,000,000 deductible per entity insured and no deductible for individual insureds. Coverage for life insurance company fiduciary liability coverage (errors and omissions) is provided under an Investment Management insurance policy issued by Chartis, with excess coverage by Chartis, The Hartford and CNA, to Mutual of America Life Insurance Company et al. The deductible is $1,000,000 for the entity, with an aggregate limit of liability under the primary policy of $30 million.

C-4

Operating Agreement of the Adviser. The Operating Agreement of Mutual of America Capital Management LLC, the Investment Company’s Adviser, provides for the indemnification by the Adviser of present and former directors and officers of the Adviser and of any organization for which service is rendered at the request of the Adviser and permits the advance payment of expenses in certain circumstances for covered persons in connection with suits by third parties and derivative suits. Each covered person must have acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the Adviser and, with respect to any criminal action or proceeding, had no reasonable cause to believe the conduct was unlawful. If in connection with a derivative suit a covered person shall have been adjudged to be liable to the Adviser, indemnification shall not be made unless and only to the extent that the Delaware Court of Chancery or the court in which such action or suit was brought shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such person is entitled to indemnity. Thus, the officers, directors and managers of the fund and the Adviser are indemnified by the Adviser for their services in connection with the Investment Company to the extent set forth in the Operating Agreement.

By-Laws of the Principal Underwriter. The By-Laws of Mutual of America Life Insurance Company, the principal underwriter for the Investment Company, provide for the indemnification by Mutual of America of present and former directors and officers of Mutual of America and of any organization for which service is rendered at the request of Mutual of America and permits the advance payment of expenses in certain circumstances for covered persons in connection with suits by third parties and derivative suits. Each covered person must have acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of Mutual of America and, with respect to any criminal action or proceeding, had no reasonable cause to believe the conduct was unlawful. Thus, the officers and directors of Mutual of America are indemnified by Mutual of America for their services in connection with the Investment Company to the extent set forth in the By-Laws.

Undertaking. Insofar as indemnification for liability arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer, or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.
