Note 4. Revenue Recognition from Contracts with Customers

Disaggregation of Revenue

The Company’s primary revenue streams include foundry fabrication services and product sales.

Foundry Fabrication Services

Foundry fabrication services revenue includes Non-Recurring Engineering (“NRE”) and microelectromechanical systems (“MEMS”) foundry services. The Company exited the MEMS business during fiscal year 2020. Under these contracts, products are delivered to the customer at the completion of the service which represents satisfaction of the performance obligation as well as transfer of title. Depending on language with regards to enforceable right to payment for performance completed to date, related revenue will either be recognized over time or at a point in time.

Product Sales

Product sales revenue consists of sales of RF filters and amps which are sold with contract terms stating that title passes, and the customer takes control at the time of shipment. Revenue is then recognized when the devices are shipped, and the performance obligation has been satisfied. If devices are sold under contract terms that specify that the customer does not take ownership until the goods are received, revenue is recognized when the customer receives the goods.

Performance Obligations

The Company has determined that contracts for product sales revenue and foundry fabrication services revenue involve one performance obligation, which is delivery of the final product.

Contract Balances

The following table summarizes the changes in the opening and closing balances of the Company’s contract asset and liability for the first nine months of fiscal years 2021 and 2020 (in thousands):

The Company records a receivable when the title for goods has transferred. Generally, all sales are contract sales (with either an underlying contract or purchase order), resulting in all receivables being contract receivables. When invoicing occurs prior to revenue recognition a contract liability is recorded (as deferred revenue on the Condensed Consolidated Balance Sheets). The contract liability balance as of March 31, 2021 comprises various upfront payments for non-recurring engineering services that will be performed subsequent to March 31, 2021. The amount of revenue recognized in the nine months ended March 31, 2020 that was included in the opening contract liability balance was $5 thousand which related to product sales.

Contract assets are recorded when revenue recognized exceeds the amount invoiced. The difference between the opening and closing balances of the Company’s contract assets and contract liabilities primarily results from the timing difference between the Company’s performance and the customer’s payment. The amount of contract assets invoiced in the nine months ended March 31, 2021 and 2020 that was included in the opening contract asset balance was $119 thousand, which primarily related to non-recurring engineering services and $96 thousand, which primarily related to non-recurring engineering services, respectively.

Backlog of Remaining Customer Performance Obligations

Revenue expected to be recognized and recorded as sales during this fiscal year from the backlog of performance obligations that are unsatisfied (or partially unsatisfied) was $2.8 million at March 31, 2021.
