Cost And Equity Method Investments Disclosure [Text Block]	15. Impairment Loss on Investment For the years ended January 3, 2015, and December 28, 2013, the Company recorded other-than-temporary impairment losses of $8.4 million and $21.5 million, respectively, on the consolidated statements of operations to write down the carrying value of its investment in equity and debt securities of Enchi. On October 31, 2014, Enchi completed the sale of its yeast business in exchange for cash and certain royalty rights based on future sales of the yeast products by the purchaser. As a consequence of this sale, the Company estimated that its investment in equity securities of Enchi was fully impaired and that the impairment was other-than-temporary. As a result, the Company recorded an impairment loss on investment of $11.9 million on the statement of operations in 2014, to write off the remaining carrying value of its equity investment. The Company also estimated that the fair value of its $1.4 million investment in convertible subordinated notes of Enchi was $4.8 million, including the value ascribed to the accelerated payment option embedded in the notes (see note 5). As a result, the Company recognized a gain on its investment in debt securities of Enchi of $3.4 million in 2014, which was recorded as a net amount against the impairment loss on investment on the statement of operations. In 2013, the Company concluded that the original $33.3 million carrying value of its investment in equity securities of Enchi was impaired and that the impairment was other-than-temporary. As a result, the Company recorded an other-than-temporary impairment loss of $21.5 million in 2013, to write down the carrying value of its equity investment from $33.3 million to $11.9 million.
