3.     Revenue Recognition

Disaggregation of Revenue

The Company recognizes revenue predominately from contract manufacturing. Revenue contract manufacturing is recognized at the point where the customer obtains control of the goods and the Company satisfies its performance obligation, which generally is at the time it ships the product to the customer.

As of June 30, 2019, and December 31, 2018, the Company did not have any contract assets or contract liabilities from contracts with customers. During the six months ended June 30, 2019 and 2018, there was no revenue recognized from performance obligations satisfied (or partially satisfied) in previous periods. As of June 30, 2019, there were no remaining performance obligations that the Company had not satisfied.
