        <Explanation>The Internal Revenue Service has determined that MHNU is a not-for profit entity under Section 501(c)(3) of the Internal Revenue Code (the Code) and is exempt from federal income taxes as a charitable organization pursuant to Section 501(a) of the Code. MHNU is also exempt from state taxation as a charitable organization. Therefore, no provision for income tax has been made in the accompanying financial statements. However, MHNU may be subject to tax on income unrelated to its exempt purposes, unless that income is otherwise excluded by the Code. Tax years open under the federal statute of limitations include 2009 through 2012. Tax years open under state statutes include 2009 through 2012. MHNU did not report any unrelated business income in any of the open tax years. MHNU classifies interest and penalties on underpayment of income taxes in the statement of activities as management and general expense. There were no interest or penalties incurred or recorded for the year ended December 31, 2012.</Explanation>
