        <Explanation>As required by the uncertain tax position guidance in Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") 740, Income Taxes, the Association and the foundation recognize the financial statement benefit of a tax position 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 percent likelihood of being realized upon ultimate settlement with the relevant tax authority. The Association and the foundation applied the uncertain tax position guidance in asc 740 to all tax positions for which the statute of limitations remained open and determined there were no material unrecognized tax benefits. as of february 28, 2011, the statute of limitations is no longer open for years before 2008 for federal income tax purposes. For state income tax purposes, the statute of limitations is no longer open for years before 2007. There were no interest or penalties related to income tax that have been accrued or recognized as of and for the years ended February 28, 2011 and 2010.</Explanation>
