    <footnotes>
        <footnote id="F1">On January 12, 2017, the Issuer effected a 1-for-30 reverse stock split of the issued and outstanding shares of its common stock.  The monthly vesting of restricted stock units (RSUs) was adjusted to reflect the reverse stock split, and as a result, 54 shares were withheld to satisfy the insider's tax withholding obligation related to the vesting of 106 RSUs.</footnote>
        <footnote id="F2">Upon effectiveness of the reverse stock split, every 30 shares of common stock was automatically converted into one share of common stock, resulting in a decrease of the insider's common stock holdings of 23,665 shares.</footnote>
