The investment, with a carrying amount of $3,126 and $3,137, at March 2, 2013 and December 1, 2012, respectively, included in Other noncurrent assets in the Consolidated Condensed Balance Sheets, is being accounted for under the equity method of accounting. The carrying amount is adjusted each period to recognize the Company’s share of the earnings or losses of BPH, included in Other, net in the Consolidated Condensed Statements of Earnings, based on the percentage of ownership, as well as the receipt of any dividends. During the three months ended March 2, 2013 and March 3, 2012, the Company did not receive any dividends from BPH. The equity investment is periodically reviewed for indicators of impairment. The Company also owns a 14.85% share in BioProcess Algae LLC (“Algae”), a Delaware-based company developing technology to grow and harvest algae which can be used to consume carbon dioxide and also be used as a renewable energy source.

The remaining 20% of SINFA owned by the noncontrolling owners has been reported as Redeemable noncontrolling interests and classified as mezzanine equity in the Consolidated Condensed Balance Sheets. The Redeemable noncontrolling interests is reflected at its carrying value, which is greater than its estimated redemption price. The Redeemable noncontrolling interests will be accreted to the redemption price, through equity, at the point at which the redemption becomes probable. The Company has not recorded any accretion to date. As of March 2, 2013, neither the Company nor the noncontrolling owners have exercised the purchase option.
