These estimates and assumptions affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities, and the reported amounts of revenues and expenses. Actual results could differ from these estimates.&lt;/font&gt;&lt;/div&gt;&lt;div style="DISPLAY: block; MARGIN-LEFT: 0pt; TEXT-INDENT: 0pt; MARGIN-RIGHT: 0pt" align="justify"&gt;&amp;#160;&lt;/div&gt;&lt;div style="DISPLAY: block; MARGIN-LEFT: 0pt; TEXT-INDENT: 18pt; MARGIN-RIGHT: 0pt" align="left"&gt;&lt;font style="DISPLAY: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman"&gt;On May 30, 2007, Kinder Morgan Kansas, Inc. completed a merger transaction with a wholly owned subsidiary of KMI under which investors including Richard D. Kinder, Kinder Morgan Kansas, Inc.&amp;#8217;s Chairman and Chief Executive Officer, acquired all of the outstanding shares of Kinder Morgan Kansas, Inc., referred to as the &amp;#8220;Going Private transaction.&amp;#8221; The purchase price of Kinder Morgan Kansas, Inc. has been &amp;#8220;pushed-down&amp;#8221; and allocated to the assets and liabilities of its subsidiary companies, including us. Accordingly, the accompanying financial information, transactions and balances reflect the push-down of Kinder Morgan Kansas, Inc.&amp;#8217;s new accounting basis arising from the 2007 Going Private transaction to our financial statements.&lt;/font&gt;&lt;/div&gt;&lt;div style="DISPLAY: block; MARGIN-LEFT: 0pt; TEXT-INDENT: 0pt; MARGIN-RIGHT: 0pt" align="justify"&gt;&amp;#160;&lt;/div&gt;&lt;div style="DISPLAY: block; MARGIN-LEFT: 0pt; TEXT-INDENT: 18pt; MARGIN-RIGHT: 0pt" align="left"&gt;&lt;font style="DISPLAY: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman"&gt;Notwithstanding the consolidation of KMP and its subsidiaries into KMI&amp;#8217;s and Kinder Morgan Kansas, Inc.&amp;#8217;s financial statements, except as explicitly disclosed, KMI and Kinder Morgan Kansas, Inc. are not liable for, and their assets are not available to satisfy, the obligations of KMP and/or its subsidiaries and vice versa.&amp;#160;&amp;#160;Responsibility for settlements of obligations reflected in KMI&amp;#8217;s , Kinder Morgan Kansas, Inc.&amp;#8217;s or KMP&amp;#8217;s financial statements are a legal determination based on the entity that incurs the liability.&lt;/font&gt;&lt;/div&gt;&lt;div style="DISPLAY: block; MARGIN-LEFT: 0pt; TEXT-INDENT: 0pt; MARGIN-RIGHT: 0pt" align="justify"&gt;&amp;#160;&lt;/div&gt;&lt;div style="DISPLAY: block; MARGIN-LEFT: 0pt; TEXT-INDENT: 18pt; MARGIN-RIGHT: 0pt" align="left"&gt;&lt;font style="DISPLAY: inline; FONT-SIZE: 10pt; FONT-STYLE: italic; FONT-FAMILY: Times New Roman"&gt;Cash Equivalents&lt;/font&gt;&lt;/div&gt;&lt;div style="DISPLAY: block; MARGIN-LEFT: 0pt; TEXT-INDENT: 0pt; MARGIN-RIGHT: 0pt" align="justify"&gt;&amp;#160;&lt;/div&gt;&lt;div style="DISPLAY: block; MARGIN-LEFT: 0pt; TEXT-INDENT: 18pt; MARGIN-RIGHT: 0pt" align="left"&gt;&lt;font style="DISPLAY: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman"&gt;We consider all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents.&lt;/font&gt;&lt;/div&gt;&lt;div style="DISPLAY: block; MARGIN-LEFT: 0pt; TEXT-INDENT: 0pt; MARGIN-RIGHT: 0pt" align="justify"&gt;&amp;#160;&lt;/div&gt;&lt;div style="DISPLAY: block; MARGIN-LEFT: 0pt; TEXT-INDENT: 18pt; MARGIN-RIGHT: 0pt" align="left"&gt;&lt;font style="DISPLAY: inline; FONT-SIZE: 10pt; FONT-STYLE: italic; FONT-FAMILY: Times New Roman"&gt;Accounting for Investment in KMP&lt;/font&gt;&lt;/div&gt;&lt;div style="DISPLAY: block; MARGIN-LEFT: 0pt; TEXT-INDENT: 0pt; MARGIN-RIGHT: 0pt" align="justify"&gt;&amp;#160;&lt;/div&gt;&lt;div style="DISPLAY: block; MARGIN-LEFT: 0pt; TEXT-INDENT: 18pt; MARGIN-RIGHT: 0pt" align="left"&gt;&lt;font style="DISPLAY: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman"&gt;We use the equity method of accounting for our investment in KMP, which investment is further described in Notes 3 and 4. KMP is a publicly traded limited partnership and is traded on the New York Stock Exchange under the symbol &amp;#8220;KMP.&amp;#8221; We record, in the period in which it is earned, our share of the earnings of KMP attributable to the i-units we own, which includes an adjustment to reflect the impact of the push down of the purchase price of Kinder Morgan Kansas, Inc. on our equity investment in KMP. We also record our proportionate share of KMP&amp;#8217;s accumulated other comprehensive income as an adjustment to our investment in KMP. We receive distributions from KMP in the form of additional i-units, which increase the number of i-units we own. We issue additional shares (or fractions thereof) of the Company to our existing shareholders in an amount equal to the additional i-units received from KMP. At December 31, 2010, through our ownership of i-units, we owned approximately 29.1% of all of KMP&amp;#8217;s outstanding limited partner interests.&lt;/font&gt;&lt;/div&gt;&lt;div style="DISPLAY: block; MARGIN-LEFT: 0pt; TEXT-INDENT: 0pt; MARGIN-RIGHT: 0pt" align="justify"&gt;&amp;#160;&lt;/div&gt;&lt;div style="DISPLAY: block; MARGIN-LEFT: 0pt; TEXT-INDENT: 18pt; MARGIN-RIGHT: 0pt" align="left"&gt;&lt;font style="DISPLAY: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman"&gt;In addition, we perform impairment testing of the amount at which we carry the excess of cost over underlying fair value of net assets accounted for under the equity method when events or circumstances warrant such testing. The impairment test considers whether there is an inability to recover the carrying value of an investment that is other than temporary. As of December 31, 2010, we believed no such impairment had occurred&amp;#160;on our investment in KMP.&lt;/font&gt;&lt;/div&gt;&lt;div style="DISPLAY: block; MARGIN-LEFT: 0pt; TEXT-INDENT: 0pt; MARGIN-RIGHT: 0pt" align="justify"&gt;&amp;#160;&lt;/div&gt;&lt;div style="DISPLAY: block; MARGIN-LEFT: 0pt; TEXT-INDENT: 18pt; MARGIN-RIGHT: 0pt" align="left"&gt;&lt;font style="DISPLAY: inline; FONT-SIZE: 10pt; FONT-STYLE: italic; FONT-FAMILY: Times New Roman"&gt;Accounting for Share Distributions&lt;/font&gt;&lt;/div&gt;&lt;div style="DISPLAY: block; MARGIN-LEFT: 0pt; TEXT-INDENT: 0pt; MARGIN-RIGHT: 0pt" align="justify"&gt;&amp;#160;&lt;/div&gt;&lt;div style="DISPLAY: block; MARGIN-LEFT: 0pt; TEXT-INDENT: 18pt; MARGIN-RIGHT: 0pt" align="left"&gt;&lt;font style="DISPLAY: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman"&gt;Our board of directors declares and we make additional share distributions at the same time that KMP declares and makes distributions on the i-units to us, so that the number of i-units we own and the number of our shares outstanding remain equal. We account for the share distributions we make by charging retained earnings and crediting outstanding shares with amounts that equal the number of shares distributed multiplied by the closing price of the shares on the date the distribution is payable. As a result, we expect that our retained earnings will always be in a deficit position because (i) distributions per unit for KMP (which serve to reduce our retained earnings) are based on &amp;#8220;Available Cash&amp;#8221; as defined by its partnership agreement, which amount generally exceeds the earnings per unit (which serve to increase our retained earnings) and (ii) the impact on our retained earnings attributable to our equity in the earnings of KMP is recorded after a provision for income taxes.&lt;/font&gt;&lt;/div&gt;&lt;div style="DISPLAY: block; MARGIN-LEFT: 0pt; TEXT-INDENT: 0pt; MARGIN-RIGHT: 0pt" align="justify"&gt;&amp;#160;&lt;/div&gt;&lt;div style="DISPLAY: block; MARGIN-LEFT: 0pt; TEXT-INDENT: 18pt; MARGIN-RIGHT: 0pt" align="left"&gt;&lt;font style="DISPLAY: inline; FONT-SIZE: 10pt; FONT-STYLE: italic; FONT-FAMILY: Times New Roman"&gt;Income Taxes&lt;/font&gt;&lt;/div&gt;&lt;div style="DISPLAY: block; MARGIN-LEFT: 0pt; TEXT-INDENT: 0pt; MARGIN-RIGHT: 0pt" align="justify"&gt;&amp;#160;&lt;/div&gt;&lt;div style="DISPLAY: block; MARGIN-LEFT: 0pt; TEXT-INDENT: 18pt; MARGIN-RIGHT: 0pt" align="left"&gt;&lt;font style="DISPLAY: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman"&gt;We are a limited liability company that has elected to be treated as a corporation for federal income tax purposes. Our entire income tax provision consists of deferred income tax.&amp;#160;&amp;#160;Deferred income tax assets and liabilities are recognized for temporary differences between the basis of our assets and liabilities for financial and tax reporting purposes.&amp;#160;&amp;#160;Our deferred tax liabilities balance was $201.7 million and $146.1 million as of December 31, 2010 and 2009, respectively, as presented in the accompanying consolidated balance sheets. Under our current basis of accounting, we have excluded nondeductible goodwill associated with our investment in KMP. Prior to the Going Private transaction we recognized temporary differences between the basis of our assets and liabilities for financial reporting and tax purposes including nondeductible goodwill associated with our investment in KMP. Changes in tax legislation are included in the relevant computations in the period in which such changes are effective. Currently, our only such temporary difference results from our investment in KMP.&lt;/font&gt;&lt;/div&gt;&lt;div style="DISPLAY: block; MARGIN-LEFT: 0pt; TEXT-INDENT: 0pt; MARGIN-RIGHT: 0pt" align="justify"&gt;&amp;#160;&lt;/div&gt;&lt;div style="DISPLAY: block; MARGIN-LEFT: 0pt; TEXT-INDENT: 18pt; MARGIN-RIGHT: 0pt" align="left"&gt;&lt;font style="DISPLAY: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman"&gt;For more information on income taxes, see Note 6.&lt;/font&gt;&lt;/div&gt;&lt;div style="DISPLAY: block; MARGIN-LEFT: 0pt; TEXT-INDENT: 0pt; MARGIN-RIGHT: 0pt" align="justify"&gt;&amp;#160;&lt;/div&gt;&lt;div style="DISPLAY: block; MARGIN-LEFT: 0pt; TEXT-INDENT: 18pt; MARGIN-RIGHT: 0pt" align="left"&gt;&lt;font style="DISPLAY: inline; FONT-SIZE: 10pt; FONT-STYLE: italic; FONT-FAMILY: Times New Roman"&gt;Earnings Per Share&lt;/font&gt;&lt;/div&gt;&lt;div style="DISPLAY: block; MARGIN-LEFT: 0pt; TEXT-INDENT: 0pt; MARGIN-RIGHT: 0pt" align="justify"&gt;&amp;#160;&lt;/div&gt;&lt;div style="DISPLAY: block; MARGIN-LEFT: 0pt; TEXT-INDENT: 18pt; MARGIN-RIGHT: 0pt" align="left"&gt;&lt;font style="DISPLAY: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman"&gt;Both basic and diluted earnings per share are computed based on the weighted-average number of shares outstanding during each period, adjusted for share splits.
