As a result of this settlement, Allegheny reversed its previously recorded accrued interest liability of $54.7 million through a credit to interest expense during the fourth quarter of 2007. On March 31, 2008, in accordance with the settlement agreement, Allegheny made a cash payment to Merrill Lynch in the amount of $50 million, and Merrill Lynch conveyed to Allegheny its approximately 1.5% equity interest in AE Supply. Allegheny recorded the acquisition of Merrill Lynch’s noncontrolling interest in AE Supply using the purchase method of accounting. Under the purchase method of accounting, the purchase price was allocated to individual assets acquired and liabilities assumed based on the fair values of such assets and liabilities. The purchase accounting adjustments will be amortized against income over the estimated lives of the individual assets and liabilities, ranging from 3 years to 30 years. No goodwill was recorded. The effects of the purchase accounting adjustments are not expected to materially impact Allegheny’s financial results for any period. Allegheny ceased recording expense relating to the noncontrolling interest in AE Supply as of January 1, 2008. </div> NOTE 24:  ACQUISITION OF NONCONTROLLING INTEREST IN AE SUPPLY On January 25, 2008, Allegheny and Merrill Lynch entered into a settlement false false No definition available.
