Revenue from Contract with Customer [Abstract]

Revenue

Note 3. Revenue

The Company accounts for revenue in accordance with ASC 606, which was adopted in fiscal 2019 using the retrospective transition method. The Company’s revenue is derived from a diverse portfolio of network solutions and optical technology products and services, as follows:

• Products: Network Enablement (“NE”) and Service Enablement (“SE”) products include instruments, microprobes and perpetual software licenses that support the development, production, maintenance and optimization of network systems. The Company’s Optical Security and Performance (“OSP”) products include proprietary pigments used for optical security and optical filters used in commercial and government 3D Sensing applications.

• Services: The Company also offers a range of product support and professional services designed to comprehensively address customer requirements. These include repair, calibration, extended warranty, software support, technical assistance, training and consulting services. Implementation services provided in conjunction with hardware or software solution projects include sale of the products along with project management, set-up and installation.

Balance sheet and other details

Unbilled Receivables: The Company records a receivable when an unconditional right to consideration exists and transfer of control has occurred, such that only the passage of time is required before payment of consideration is due. Timing of revenue recognition may differ from the timing of customer invoicing. Payment terms vary based on product or service offerings and payment is generally required within 30 to 90 days from date of invoicing. Certain performance obligations may require payment before delivery of the service to the customer.

Contract Assets: A Contract Asset is recognized when a conditional right to consideration exists and transfer of control has occurred. Contract Assets include fixed fee professional services, where the transfer of services has occurred in advance of the Company's right to invoice. Contract Assets, included in accounts receivable, net, on the Consolidated Balance Sheets, are not material to the Consolidated Financial Statements. The prior year’s Consolidated Balance Sheets and Statements of Cash Flows have been updated to conform to the current period’s presentation. Contract asset balances will fluctuate based upon the timing of transfer of services, billings and customers’ acceptance of contractual milestones.

Gross receivables include both billed and Unbilled Receivables/Contract Assets. For the three months ended September 28, 2019 and June 29, 2019 the Company had total non-billed receivables (Unbilled Receivables/Contract Assets) of $5.5 million and $11.5 million, respectively.

Deferred Revenue: Deferred revenue consists of contract liabilities primarily related to support, solution deployment services, software maintenance, product, professional services, and training when the Company has a right to invoice or payments have been received and transfer of control has not occurred. Revenue is recognized on these items when the revenue recognition criteria are met, generally resulting in ratable recognition over the contract term. Contract liabilities are included in deferred revenue and non-current liabilities on the Consolidated Balance Sheets.

The Company also has short term and long term deferred revenues related to undelivered hardware and professional services, consisting of installations and consulting engagements, which are recognized as the Company's performance obligations under the contract are completed and accepted by the customer.

The following tables summarize the activity related to deferred revenue (in millions):

	September 28, 2019
	Three Months Ended
Deferred revenue:
Balance at beginning of period	$	68.5
Revenue deferrals for new contracts (1)	18.9
Revenue recognized during the period	(23.0		)
Balance at end of period	$	64.4
Short-term deferred revenue	$	51.2
Long-term deferred revenue	$	13.2

⁽¹⁾  Included in these amounts is the impact from foreign currency exchange rate fluctuations.

Remaining Performance Obligations: Remaining performance obligations represent the aggregate amount of the transaction price allocated to performance obligations not delivered or are incomplete, as of September 28, 2019. Remaining performance obligations include deferred revenue plus unbilled amounts not yet recorded. The aggregate amount of the transaction price allocated to remaining performance obligations does not include amounts owed under cancelable contracts where there is no substantive termination penalty.

Remaining performance obligation estimates are subject to change and are affected by several factors, including terminations, changes in the scope of contracts, periodic revalidation, adjustments for revenue that has not materialized, and adjustments for currency.

The value of the transaction price allocated to remaining performance obligations as of September 28, 2019, was $228.9 million. The Company expects to recognize 92% of remaining performance obligations as revenue within the next 12 months, and the remainder thereafter.

Disaggregation of revenue

The Company's revenue is presented on a disaggregated basis on the Consolidated Statements of Operations and in “Note 19. Operating Segments and Geographic Information”. This information includes revenue from reportable segments and a break-out of products and services for which the nature and timing of the revenue as characterized above is generally at a point in time and over time, respectively.
