NOTE 2: SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Revenue Recognition

In accordance with FASB ASC 606 - Revenue from Contracts with Customers (“ASC 606“), the Company records revenue in an amount that reflects the consideration to which the Company expects to be entitled in exchange for goods or services promised to its customers. Under ASC 606, the Company follows a five-step model to: (1) identify the contract with the customer; (2) identify the performance obligations in the contract; (3) determine the transaction price for the contract; (4) allocate the transaction price to the performance obligations; and (5) recognize revenue using one of the following two methods:

Over time

The Company designs, manufactures and sells specialized chemical vapor deposition equipment through contractual agreements. These system sales require the Company to deliver functioning equipment that is generally completed within two to eighteen months from order acceptance. The Company recognizes revenue from system sales over time by using an input method based on costs incurred as it depicts the Company’s progress toward satisfaction of the performance obligation. Under this method, revenue arising from fixed price contracts is recognized as work is performed based on the ratio of costs incurred to date to the total estimated costs at completion of the performance obligations. Incurred costs include all direct material and labor costs and those indirect costs related to contract performance, such as supplies, tools, repairs and depreciation costs. Contract material costs are included in incurred costs when the project materials have been purchased or moved to work in process, and installed, as required by the project’s engineering design.

There were no material impairment losses recognized on contract assets during the three months ended March 31, 2023 and 2022.

The timing of revenue recognition, billings and collections results in receivables, unbilled receivables (referred to as contract assets) and contract liabilities on our consolidated balance sheet. Under typical payment terms for our contracts accounted for over time, amounts are billed as work progresses in accordance with agreed-upon contractual terms, either at periodic intervals or upon achievement of contractual milestones.

Also, advanced payments and deposits provide us with some measure of assurance that the customer will perform on its obligations under the contract.

Contract assets include unbilled amounts typically resulting from system sales under contracts and represents revenue recognized that exceeds the amount billed to the customer.

Contract liabilities include advance payments and billings in excess of revenue recognized. The Company typically receives down payments upon receipt of order and progress payments as the system is manufactured.

Contract assets and contract liabilities are classified as current as these contracts in progress are expected to be substantially completed within the next twelve months.
