Revenue from Contract with Customer [Text Block]

Note 2. Revenue Recognition:

Consumables revenues consist of single-use products and are recognized at a point in time following the transfer of control of such products to the customer, which generally occurs upon shipment. Instruments revenues typically consist of longer-lived assets that, for the substantial majority of sales, are recognized at a point in time in a manner similar to consumables. Service revenues consist of extended warranty contracts, post contract support (“PCS”), and custom development projects that are recognized over time as either the customers receive and consume the benefits of such services simultaneously or the underlying asset being developed has no alternative use for the Company at contract inception and the Company has an enforceable right to payment for the portion of the performance completed. Service revenues also include laboratory services recognized at a point in time. Prior to fiscal year 2021, the Company has not recognized revenue upon completion of the performance obligation for laboratory services, but rather upon cash receipt, which was subsequent to the performance obligation being satisfied. The Company accounted for these services based on cash receipts as we did not have significant historical experience collecting payments from Medicare or other insurance providers and considered the variable consideration for such services to be constrained as it would not be probable that a significant amount of revenue would not need to be reversed in future periods for the services provided. Given Medicare coverage for our laboratory services became effective on December 1, 2019, the Company considered that it had sufficient data to estimate variable consideration as of July 1, 2020 for laboratory services that are reimbursed by Medicare. The amount of cash received in fiscal year 2021 for laboratory services reimbursed by Medicare that were performed prior to July 1, 2020 was approximately $0.5 million. The Company continues to record revenue based on cash receipts for laboratory services not reimbursed by Medicare, as the variable consideration remains constrained. We recognize royalty revenues in the period the sales occur using third party evidence. The Company elected the "right to invoice" practical expedient based on the Company's right to invoice a customer at an amount that approximates the value to the customer and the performance completed to date.

The Company elected the exemption to not disclose the unfulfilled performance obligations for contracts with an original length of one year or less and the exemption to exclude future performance obligations that are accounted under the sales-based or usage-based royalty guidance.  The Company's unfulfilled performance obligations for contracts with an original length greater than one year were not material as of June 30, 2021 and June 30, 2020.

Contracts with customers that contain instruments may include multiple performance obligations. For these contracts, the Company allocates the contract’s transaction price to each performance obligation on a relative standalone selling price basis. Allocation of the transaction price is determined at the contracts’ inception.

Payment terms for shipments to end-users are generally net 30 days. Payment terms for distributor shipments may range from 30 to 90 days. Service arrangements commonly call for payments in advance of performing the work (e.g. extended warranty and service contracts), upon completion of the service (e.g. custom development manufacturing) or a mix of both.

Contract assets include revenues recognized in advance of billings. Contract assets are included within other current assets in the accompanying balance sheet as the amount of time expected to lapse until the company's right to consideration becomes unconditional is less than one year. We elected the practical expedient allowing us to expense contract costs that would otherwise be capitalized and amortized over the contract period. Contract assets as of June 30, 2021 are not material.

Contract liabilities include billings in excess of revenues recognized, such as those resulting from customer advances and deposits and unearned revenue on warranty contracts. Contract liabilities as of June 30, 2021 and June 30, 2020 were approximately $20.0 million and $14.2 million, respectively. Contract liabilities as of June 30, 2020 subsequently recognized as revenue during the year ended June 30, 2021 were approximately $10.6 million. Contract liabilities in excess of one year are included in Other long-term liabilities on the balance sheet. 

Any claims for credit or return of goods must be made within 10 days of receipt. Revenues are reduced to reflect estimated credits and returns. Although the amounts recorded for these revenue deductions are dependent on estimates and assumptions, historically our adjustments to actual results have not been material.

Taxes collected from customers relating to product sales and remitted to governmental authorities are excluded from revenue. Amounts billed to customers for shipping and handling are included in revenue, while the related shipping and handling costs are reflected in cost of products. We have elected the practical expedient that allows us to account for shipping and handling activities that occur after the customer has obtained control of a good as a fulfillment cost, and we accrue costs of shipping and handling when the related revenue is recognized.
