        <Explanation>Mather LifeWays; Mather Foundation; Mather Healthcare, Inc.; Mather Investments, NFP; Mather Possibilities; and The Mather have received determination letters from the Internal Revenue Service indicating that they are exempt from federal income taxes, except for taxes pertaining to unrelated business income, under Section 501(c)(3) of the Internal Revenue Code. As required by uncertain tax position guidance, the benefit from a tax position is only after determining that the relevant tax authority would more likely than not sustain the position following an audit. For tax positions meeting the more likely than not threshold, the amount recognized in the financial statements is the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement with the relevant tax authority. The entities of Mather LifeWays applied the uncertain tax position guidance to all tax positions for which the statute of limitations remained open. Taxation regulations within each jurisdiction are subject to the interpretation of the related tax laws and regulations and require significant judgment to apply. Tax years open to examination by tax authorities under federal statute of limitations include calendar years 2009, 2010, 2011 and 2012. The entities of Mather LifeWays file tax returns in certain states; however, they do not file in every state. For all states where the entities have not filed a state return, all tax years remain open.</Explanation>

        <Explanation>Mather Foundation's top management's compensation is established by Mather LifeWays, as the compensation is paid by Mather LifeWays (a related organization). Mather LifeWays follows procedures to establish the "rebuttable" presumption of reasonableness described in the Income Tax Regulations in determining executive compensation. Compensation is reviewed annually by the Board's Compensation Committee, which consists of independent directors who obtain and rely on appropriate data as to comparability. Objective evidence of reasonableness and comparability is obtained from information provided by an independent, third party compensation consultant. Determination of executive compensation involves benchmarking with comparative market compensation data to ensure that compensation is fair, equitable, and within the standards of compensation utilized within the industry. Compensation decisions are documented and reviewed with the full Board.</Explanation>
