[1] The majority of the equity in unconsolidated investments relates to ALP. In 2008, the Company wrote-off its investment in ALP as a result of ALP reserving its assets to satisfy potential claims and obligations in accordance with its publicly reported liquidation basis of accounting. Subsequently, ALP changed its method of accounting to a going concern basis and reinstated its equity and stated it would report certain expenses as they are incurred. The Company has not recorded any additional equity income as a result of the ALP’s change in accounting.
