Revenues from Contracts with Customers Other Revenues

The Company’s current and historical revenues have consisted of the following: (a) ethanol sales and related products revenue, net; (b) hydrocarbon revenue; and (c) grant and other revenue, which primarily has historically consisted of revenues from governmental and cooperative research grants.

Ethanol sales and related products revenues, net.

Ethanol sales and related products revenues, net are sold to customers on a “free-on-board, shipping point” basis. Each transaction occurs independent of any other sale, and once sold, there are

future obligations on the part of the Company to provide post-sale support or promises to deliver future goods or services.

Hydrocarbon revenue.

Hydrocarbon revenues include sales of ATJ, isooctene and isooctane and are sold mostly on a “free-on-board, shipping point” basis. Each transaction occurs independent of any other sale, and once sold, there are

future obligations on the part of the Company to provide post-sale support or promises to deliver future goods or services.

Grant and other revenues.

Grant and other revenues primarily have historically consisted of governmental and cooperative research grants, of which the

NARA grant, funded by the USDA, comprised the majority of those revenues since

2014.

After reviewing this arrangement, the Company has concluded that this grant consists of a non-reciprocal arrangement, and therefore, does

not

qualify as a contract pursuant to Topic

606

“

Revenues from Contracts with Customers”

. Other revenues also include occasional short-term (less than

one

-year) consulting services and until

December 2017,

the lease of the Company’s corn storage bins at its Luverne, Minnesota facility.

The following table sets forth the components of the Company’s revenues between those generated from contracts with customers and those generated from arrangements that do

not

constitute a contract with a customer (in thousands):
