Interim condensed consolidated financial statements do not include all of the information and notes required by GAAP for audited annual consolidated financial statements. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2009 as recast in Item 9.01 exhibit 99.1 of the Company's Current Report on Form 8-K filed with the Securities and Exchange Commission on September 30, 2010.</font></div><div style="TEXT-INDENT: 0pt; DISPLAY: block"><br /></div><div style="TEXT-INDENT: 0pt; DISPLAY: block; MARGIN-LEFT: 0pt; MARGIN-RIGHT: 0pt" align="left"><font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt">The preparation of the condensed consolidated financial statements and notes in conformity with GAAP requires that management make estimates and assumptions that affect the amounts of revenues, expenses, assets and liabilities, and disclosure of contingent assets and liabilities.

White River Hub, LLC is a limited liability corporation and FERC-regulated transporter of natural gas. Questar Pipeline owns 50% of White River Hub, LLC and is the operator. Generally, the investment in White River Hub, LLC on the Company’s consolidated balance sheets equals the Company’s proportionate share of equity reported by White River Hub, LLC. Investment is assessed for possible impairment when events indicate that the fair value of the investment may be below the Company’s carrying value. When such a condition is deemed to be other than temporary, the carrying value of the investment is written down to its fair value, and the amount of the write-down is included in the determination of net income.</font></div><div style="TEXT-INDENT: 0pt; DISPLAY: block"><br /></div><div style="TEXT-INDENT: 0pt; DISPLAY: block; MARGIN-LEFT: 0pt; MARGIN-RIGHT: 0pt" align="left"><font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt">Effective May 18, 2010, Questar Market Resources, Inc., a wholly-owned subsidiary of Questar, merged with and into its newly-formed, wholly-owned subsidiary, QEP Resources, Inc.
