(the &amp;#8220;Partnership&amp;#8221;), a Delaware limited partnership formed in January 2010, is principally focused on natural gas gathering, the first segment of midstream energy infrastructure that connects natural gas produced at the wellhead to third-party takeaway pipelines. The Partnership is the industry&amp;#8217;s largest gathering and processing master limited partnership as measured by throughput volume. The Partnership&amp;#8217;s assets are located in Arkansas, Kansas, Louisiana, Maryland, New York, Ohio, Oklahoma, Pennsylvania, Texas, Virginia, West Virginia and Wyoming. The Partnership provides gathering, treating and compression services to Chesapeake Energy Corporation (&amp;#8220;Chesapeake&amp;#8221;), Total Gas and Power North America, Inc.

As a result of the CMO Acquisition, the Partnership now owns certain midstream assets in the Eagle Ford, Utica and Niobrara regions. The CMO Acquisition also extended the Partnership&amp;#8217;s assets and operations in the Haynesville, Marcellus and Mid-Continent regions. The acquired assets included, in the aggregate, approximately &lt;/font&gt;&lt;font style="font-family:Arial; font-size:10pt; "&gt;1,675&lt;/font&gt;&lt;font style="font-family:Arial; font-size:10pt"&gt; miles of pipeline and &lt;/font&gt;&lt;font style="font-family:Arial; font-size:10pt; "&gt;4.3&lt;/font&gt;&lt;font style="font-family:Arial; font-size:10pt; "&gt;&amp;#160;&lt;/font&gt;&lt;font style="font-family:Arial; font-size:10pt"&gt;million (gross) dedicated acres as of the date of the acquisition.

			&lt;p style="margin:12pt 0pt 0pt; text-indent:24.5pt"&gt;&lt;font style="font-family:Arial; font-size:10pt"&gt;Concurrently with the CMO Acquisition, the GIP I Entities sold to Williams &lt;/font&gt;&lt;font style="font-family:Arial; font-size:10pt; "&gt;34,538,061&lt;/font&gt;&lt;font style="font-family:Arial; font-size:10pt"&gt; of the Partnership&amp;#8217;s subordinated units and &lt;/font&gt;&lt;font style="font-family:Arial; font-size:10pt; "&gt;50&lt;/font&gt;&lt;font style="font-family:Arial; font-size:10pt"&gt;% of the outstanding equity interests in Access Midstream Ventures, L.L.C., the sole member of the Partnership&amp;#8217;s general partner, for cash consideration of approximately $&lt;/font&gt;&lt;font style="font-family:Arial; font-size:10pt; "&gt;1.8&lt;/font&gt;&lt;font style="font-family:Arial; font-size:10pt"&gt; billion (the &amp;#8220;Williams Acquisition&amp;#8221;). The Partnership did not receive any cash proceeds from the Williams Acquisition. As a result of the closing of the Williams Acquisition, the GIP II Entities and Williams together own and control the Partnership&amp;#8217;s general partner and the GIP I Entities no longer have any ownership interest in the Partnership or its general partner. &lt;/font&gt;&lt;/p&gt;

In the opinion of management, the interim data includes all adjustments, consisting only of normal recurring adjustments, necessary to a fair statement of the results for the interim periods. Certain footnote disclosures normally included in the financial statements prepared in accordance with GAAP have been appropriately condensed or omitted in this quarterly report on Form 10-Q (this &amp;#8220;Form 10-Q&amp;#8221;). Management believes the disclosures made are adequate to make the information presented not misleading.
