   to the consolidated financial statements as of and for the period ended December&amp;#160;31, 2010 included
   in ITC Holdings&amp;#8217; Form 10-K for such period.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;The accompanying condensed consolidated financial statements have been prepared using
   accounting principles generally accepted in the United States of America (&amp;#8220;GAAP&amp;#8221;) and with the
   instructions to Form 10-Q and Rule&amp;#160;10-01 of Securities and Exchange Commission (&amp;#8220;SEC&amp;#8221;) Regulation
   S-X as they apply to interim financial information. Accordingly, they do not include all of the
   information and notes required by GAAP for complete financial statements. These accounting
   principles require us to use estimates and assumptions that impact the reported amounts of assets,
   liabilities, revenues and expenses, and the disclosure of contingent assets and liabilities. Actual
   results may differ from our estimates.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;The condensed consolidated financial statements are unaudited, but in our opinion include all
   adjustments (consisting of normal recurring adjustments) necessary for a fair statement of the
   results for the interim period. The interim financial results are not necessarily indicative of
   results that may be expected for any other interim period or the fiscal year.
