Subsequent to the Merger, Foundation was renamed Alpha Natural Resources, Inc. (the “Company” or “New Alpha”) (see Note 18). For accounting purposes, the Merger was treated as a “reverse acquisition” with Old Alpha considered the accounting acquirer.

The preparation of the Company’s condensed consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period; however, in the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Significant items subject to estimates and assumptions include inventories; mineral reserves; allowance for non-recoupable advanced mining royalties; asset impairments; environmental and reclamation obligations; pensions; coal supply agreements; postemployment, postretirement and other employee benefit obligations; future cash flows associated with assets; useful lives for depreciation, depletion, and amortization; workers’ compensation and black lung claims; postretirement benefits other than pensions; valuation allowances for deferred income taxes; income tax provision calculations; reserves for contingencies and litigation; revenue recognized using the percentage of completion method; and fair value of financial instruments. Due to the subjective nature of these estimates, actual results could differ from those estimates. Results of operations for the three and nine months ended September 30, 2009 are not necessarily indicative of the results to be expected for the year ending December 31, 2009. These financial statements should be read in conjunction with Old Alpha’s audited financial statements and related notes as of and for the year ended December 31, 2008 included in Old Alpha’s Form 8-K filed on May 22, 2009 with the Securities and Exchange Commission.</font></div> <div style="DISPLAY: block; TEXT-INDENT: 0pt"><br /></div> <div style="DISPLAY: block; MARGIN-LEFT: 0pt; TEXT-INDENT: 18pt; MARGIN-RIGHT: 0pt" align="justify"><font style="DISPLAY: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman">Subsequent to the Merger with Foundation, the Company’s results of operations are and will be affected by the following significant accounting policy:</font></div> <div style="DISPLAY: block; TEXT-INDENT: 0pt"><br /></div> <div style="DISPLAY: block; MARGIN-LEFT: 0pt; TEXT-INDENT: 18pt; MARGIN-RIGHT: 0pt" align="justify"><font style="DISPLAY: inline; FONT-SIZE: 10pt; FONT-STYLE: italic; FONT-FAMILY: Times New Roman">Defined Benefit Retirement Plans</font></div> <div style="DISPLAY: block; TEXT-INDENT: 0pt"><br /></div> <div style="DISPLAY: block; MARGIN-LEFT: 0pt; TEXT-INDENT: 18pt; MARGIN-RIGHT: 0pt" align="justify"> <div style="DISPLAY: block; MARGIN-LEFT: 0pt; TEXT-INDENT: 18pt; MARGIN-RIGHT: 0pt" align="left"><font style="DISPLAY: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman">The Company is required to recognize the overfunded or underfunded status of a defined benefit pension plan as an asset or liability on its balance sheet and to recognize changes in that funded status in the year in which the changes occur through other comprehensive (loss) income.
