[1] Pioneer germplasm is the pool of genetic source material and body of knowledge gained from the development and delivery stage of plant breeding. The company recognized germplasm as an intangible asset upon the acquisition of Pioneer. This intangible asset is expected to contribute to cash flows beyond the foreseeable future and there are no legal, regulatory, contractual, or other factors which limit its useful life.

[2] Microbial cell factories, derived from natural microbes, are used to sustainably produce enzymes, peptides and chemicals using natural metabolic processes. The company recognized the microbial cell factories as intangible assets upon the acquisition of Danisco. As a result of the valuation as part of the merger, it was determined that this now has a definite life and therefore it has been moved from indefinite-lived to definite-lived as of September 1, 2017.

[3] Primarily consists of sales and grower networks, marketing and manufacturing alliances and noncompetition agreements.
