Note 5.

Revenues and Trade Receivables, Net

The Company’s revenues to date have been earned from partnered commercialized products, research and development services provided to customers, licensing of patent-protected intellectual property and commercialization of a proprietary product. These activities generate revenues in four primary categories: manufacturing and supply revenue, co-development and research fees, license and royalty revenue, and proprietary product sales, net.

Performance Obligations

A performance obligation is a promise in a contract to transfer a distinct good or service to the customer and is the unit of account in the current revenue standard. A contract’s transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, the performance obligation is satisfied. At contract inception, we assess the goods promised in our contracts with customers and identify a performance obligation for each promise to transfer to the customer a good that is distinct. When identifying our performance obligations, we consider all goods or services promised in the contract regardless of whether explicitly stated in the customer contract or implied by customary business practices. The Company’s performance obligations consist mainly of transferring control of goods and services identified in the contracts, purchase orders or invoices.

The Company’s performance obligation with respect to its proprietary product sales is satisfied at a point in time which transfers control upon delivery of the product to its customers. The Company considers control to have transferred upon delivery because the customer has legal title to the asset, physical possession of the asset has been transferred, the customer has significant risks and rewards of ownership of the asset and the Company has a present right to payment at that time. With respect to manufacturing and supply revenue stream, a quantity is ordered and manufactured according to customer’s specifications and represents a single performance obligation. The products manufactured are exclusively for specific customers and have no alternative use. Under the customer arrangements, the Company is entitled to receive payments for progress made to date once the acceptance requirements surrounding quality control are satisfied. Thus, revenues related to this product stream is recognized at a point in time, when the manufactured product passes quality control testing.

Royalty revenues are estimated based on the provisions of contracts with customers and recognized in the same period that the royalty-based products are sold to the Company’s strategic partners, as all royalties are directly attributable to the Company’s manufacturing activities, and are therefore recognizable at the same time the manufacturing revenue is recognizable. In addition to usage-based royalties, licensing contracts may contain provisions for one-time payments related to certain license fees and milestone achievements. Revenue recognition of these license fees and milestone payments depend on the nature of the specific contract, typically license and milestone payments are recognized at a point in time in the period they are achieved. However, there are limited instances where upon review of the contract, it is determined that the license is non-distinct and limited in nature and does not provide benefit to the customer without purchasing the product, these upfront licensing fees are recognized over time (typically the length of the contract).

Co-development and research fee revenue is recorded over time based upon the progress of services provided in order to complete the specific performance obligation identified in the related contract.

Revenues from sale of products and services and the subsequent related payments are evidenced by a contract with the customer, which includes all relevant terms of sale. For manufacturing and supply and proprietary product sales, invoices are generally issued upon the transfer of control and co-development and research revenue is typically invoiced based on the contractual payment schedule, or upon completion of the service. Invoices are typically payable 30 to 60 days after the invoice date, however some payment terms may reach 105 days depending on the customer. The Company performs a review of each specific customer’s credit worthiness and ability to pay prior to acceptance as a customer. Further, the Company performs periodic reviews of its customers’ creditworthiness, prospectively.

Contract Assets

In limited situations, certain customer contractual payment terms require billing to occur in arrears; accordingly, some portions, or all, of the Company’s performance obligations are completed before we are contractually entitled to bill the customer. In these situations, billing occurs subsequent to revenue recognition, which results in a contract asset. These contract assets are reflected as a component of Trade and other receivables on the Condensed Consolidated Balance Sheet. As of June 30, 2019 and January 1, 2019, such contract assets were $295, and $284, respectively.

Contract Liabilities

In other limited situations, certain customer contractual payment terms allow advanced billings; accordingly, customer cash payments may be received before satisfaction of some or all contractual performance obligations. In these situations, billing occurs in advance of revenue recognition, which results in contract liabilities. These contract liabilities are reflected as Deferred revenue in the Consolidated Balance Sheet. As remaining performance obligations are satisfied, a portion of the deferred revenue balance is recognized in the Company’s results of operations. As of June 30, 2019 and January 1, 2019, such contract liabilities were $2,866 and $3,762, respectively. Revenue recognized for the six-month period ended June 30, 2019 that was reflected in the deferred revenue balance as of January 1, 2019 was $940.

Sales Related Allowances and Accruals

Revenues from sales of products are recorded net of prompt payment discounts, wholesaler service fees, returns allowances, rebates and co-pay card redemptions. These reserves are based on estimates of the amounts earned or to be claimed on the related sales. These amounts are treated as variable consideration, estimated and recognized as a reduction of the transaction price at the time of the sale. The Company includes these estimated amounts in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized for such transaction will not occur, or when the uncertainty associated with the variable consideration is resolved. The calculation of some of these items requires management to make estimates based on sales data, historical return data, contracts and other related information that may become known in the future. The adequacy of these provisions is reviewed on a quarterly basis.

The following table provides a summary of activity with respect to our sales related allowances and accruals for the six months ended June 30, 2019:

	Total Sales Related Allowances and Accruals

Balance at December 31, 2018	$	585
Provision		847
Payments / credits		(535	)
Balance at June 30, 2019	$	897

Total reductions of gross product sales from sales-related allowances and accruals were $847 for the six months ended June 30, 2019. Accruals for returns allowances and prompt pay discounts are reflected as a direct reduction to trade receivables, and totaled $88 and $104 at June 30, 2019 and December 31, 2018, respectively. Accruals for wholesaler fees, co-pay cards and rebates are reflected as current liabilities, and totaled $809 and $481 at June 30, 2019 and December 31, 2018, respectively. There were no sales related allowances and accruals at June 30, 2018, as Sympazan was launched in December 2018.

Concentration of Major Customers
