        <Explanation>Cato has been granted tax-exempt status as a public charity within the meaning of Section 501(c)(3) of the Internal Revenue Code. Cato has been classified by the Internal Revenue Service as a public charity. Although the organization is generally exempt from income tax, it is subject to tax on certain unrelated business income. There was no unrelated business income for the years ended March 31, 2012 and 2011; therefore, no provision for income tax has been recorded in the financial statements. Cato believes it has appropriate support for any tax position taken and, as such, does not have any uncertain tax positions that are material to the financial statements. Cato recognizes interest expense and penalties on its tax positions in management and general expenses on the statements of activities and changes in net assets. Tax years prior to 2008 are no longer subject to examination by the IRS and the tax jurisdictions of Kansas and the District of Columbia.</Explanation>
