    <footnotes>
        <footnote id="F1">The shares beneficially owned by the reporting person have been adjusted downward by the de minimis amount of 512 shares believed to result from one or more computational errors arising from reverse stock splits that occurred in 2011 and 2013. The origin of the discrepancy, however, remains uncertain and the reporting person includes this footnote solely for tracking purposes.</footnote>
