Investments [Abstract]
Investments	Investments Joint ventures and other investments, in which we have significant ownership and influence, but not control, are accounted for in our consolidated financial statements using the equity method of accounting. Our significant equity method investments are summarized below. During the first three quarters of fiscal 2014, we had a 24% interest in Horizon Milling, LLC and Horizon Milling, ULC, which were flour milling joint ventures with Cargill, Incorporated (Cargill) and were accounted for as equity method investments included in Corporate and Other. In our third quarter of fiscal 2014, we formed Ardent Mills LLC (Ardent Mills), a joint venture with Cargill and ConAgra Foods, Inc., which combines the North American flour milling operations of the three parent companies, including the Horizon Milling, LLC and Horizon Milling G.P. (Horizon Milling) assets and CHS-owned mills, with CHS holding a 12% interest in Ardent Mills. Prior to closing, we contributed $32.8 million to Horizon Milling to pay off existing debt as a pre-condition to close. Upon closing, Ardent Mills was financed with funds from third-party borrowings, which did not require credit support from the owners. We received $121.2 million of cash proceeds distributed to us in proportion to our ownership interest, adjusted for deviations in specified working capital target amounts, and recognized a gain of $109.2 million associated with this transaction. In connection with the closing, the parties also entered into various ancillary and non-compete agreements including, among other things, an agreement for us to supply Ardent Mills with certain wheat and durum products. As we hold one of the five board seats, we account for Ardent Mills as an equity method investment included in Corporate and Other. As of August 31, 2014, the carrying value of our investment in Ardent Mills was $198.4 million. We have a 50% interest in Ventura Foods, LLC (Ventura Foods), a joint venture which produces and distributes primarily vegetable oil-based products, and is included in Corporate and Other. We account for Ventura Foods as an equity method investment, and as of August 31, 2014, our carrying value of Ventura Foods exceeded our share of its equity by $12.9 million, which represents equity method goodwill. As of August 31, 2014, the carrying value of our investment in Ventura Foods was $321.3 million. TEMCO, LLC (TEMCO) is owned and governed by Cargill (50%) and CHS (50%). During the year ended August 31, 2012, we entered into an amended and restated agreement to expand the scope of the original agreement with Cargill. Pursuant to the terms of the agreement, CHS and Cargill each agreed to commit to sell all of their feedgrains, wheat, oilseeds and by-product origination that are tributary to the Pacific Northwest, United States (Pacific Northwest) to TEMCO and to use TEMCO as their exclusive export-marketing vehicle for such grains exported through the Pacific Northwest for a term of 25 years. Cargill's Tacoma, Washington facility will continue to be subleased to TEMCO. We account for TEMCO as an equity method investment included in our Ag segment. As of August 31, 2014, the carrying value of our investment in TEMCO was $68.4 million.
