Step Acquisition Description				The additional 39 percent interest acquired resulted in the Company obtaining a controlling financial interest in the JV and accordingly, the purchase was accounted for as a step-acquisition. Upon consolidation, the Company recognized a $10.1 million deferred gain, which resulted from the original sale of its New Zealand operations to the joint venture in 2005 and a $6 million benefit due to the required fair market value remeasurement of the Company’s equity interest in the JV held before the purchase of the additional interest.

Acquisition-date fair value of previous equity interest						93,253,000
Business Acquisition, Purchase Price Allocation, Methodology				We have applied estimates and judgments in order to determine the fair value of assets acquired and liabilities assumed at the acquisition date. In determining fair value we utilized valuation methodologies including discounted cash flow analysis. The assumptions made in performing these valuations include assumptions as to discount rates, foreign exchange rates, and commodity prices. Any significant change in key assumptions may cause the acquisition accounting to be revised.
