Burlington Northern Santa Fe, LLC (BNSF) is a holding company that conducts no operating activities and owns no significant assets other than through its interests in its subsidiaries. The Consolidated Financial Statements include the accounts of BNSF and its majority-owned subsidiaries, all of which are separate legal entities (collectively, the Company). BNSF&amp;#8217;s principal operating subsidiary is BNSF Railway Company (BNSF Railway). All intercompany accounts and transactions have been eliminated.&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;&amp;#160;&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;On February 12, 2010, Berkshire Hathaway Inc., a Delaware corporation (Berkshire), acquired &lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;"&gt;100%&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt; of the outstanding shares of Burlington Northern Santa Fe Corporation common stock that it did not already own. The acquisition was completed through the merger of a wholly-owned merger subsidiary and Burlington Northern Santa Fe Corporation with the surviving entity renamed Burlington Northern Santa Fe, LLC. Berkshire's cost of acquiring BNSF was pushed-down to establish a new accounting basis for BNSF beginning as of February 13, 2010. Earnings per share data has not been presented because BNSF has not issued stock or membership interests to the public.&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;&lt;br clear="none"/&gt;&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;The results of operations for any interim period are not necessarily indicative of the results of operations to be expected for the entire year. In the opinion of management, the unaudited financial statements reflect all adjustments (consisting of only normal recurring adjustments, except as disclosed) necessary for a fair statement of BNSF&amp;#8217;s consolidated financial position as of &lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;"&gt;June&amp;#160;30, 2013&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;, and the results of operations for the three and &lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;"&gt;six&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt; months ended &lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;"&gt;June&amp;#160;30, 2013&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt; and &lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;"&gt;2012&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;.&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;&lt;br clear="none"/&gt;&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;font-weight:bold;"&gt;&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;Certain prior year amounts in the Consolidated Statements of Cash Flows have been reclassified to conform to the current presentation of capital expenditures.
