Revenue from Contract with Customer [Abstract]
REVENUE	REVENUE The Company's revenue recognition policy is to recognize revenues from product sales, software and services in accordance with ASC Topic 606, Revenue from Contracts with Customers. Revenue is recognized when obligations under the terms of a contract with a customer are satisfied; this occurs with the transfer of control of the Company’s goods or services. The Company considers revenue to be earned when all of the following criteria are met: it has a contract with a customer that creates enforceable rights and obligations; promised products or services are identified; the transaction price, or the consideration it expects to receive for transferring goods or providing services, is determinable and it has transferred control of the promised items to the customer. A promise in a contract to transfer a distinct good or service to the customer is identified as a performance obligation. A contract’s transaction price is allocated to each performance obligation and recognized as revenue when, or as, the performance obligation is satisfied. Some of the Company’s contracts have multiple performance obligations. For contracts with multiple performance obligations, the Company allocates the contract’s transaction price to each performance obligation based on the estimated standalone selling prices of the good or service in the contract. For goods or services for which observable standalone selling prices are not available, the Company uses an expected cost plus a margin approach to estimate the standalone selling price of each performance obligation. As of September 29, 2018, the Company had $26.2 million of its transaction price allocated to remaining performance obligations related to executed contracts with an original duration of one year or more. The Company expects to recognize approximately 57% of this amount as revenue within the next twelve months and the remaining balance thereafter. The Company adopted Topic 606 as of April 1, 2018, using the modified retrospective method. Under this method, entities recognize the cumulative effect of applying the new standard at the date of initial application with no restatement of comparative periods presented. The cumulative effect of applying the new standard resulted in an increase to opening retained earnings of $1.5 million upon adoption of Topic 606 on April 1, 2018, primarily related to deferred revenue associated with software revenue. The new standard has been applied only to those contracts that were not completed as of March 31, 2018. The impact of adopting Topic 606 was not significant to individual financial statement line items in the consolidated balance sheet as of September 29, 2018 or in the consolidated statements of income and comprehensive income for the three and six months ended September 29, 2018. Product Revenues The majority of the Company’s performance obligations related to product sales are satisfied at a point in time. Product sales consist of the sale of its disposable blood component collection and processing sets and the related equipment. The Company’s performance obligation related to product sales is satisfied upon shipment or delivery to the customer based on the specified terms set forth in the customer contract. Shipping and handling activities performed after a customer obtains control of the good are treated as fulfillment activities and are not considered to be a separate performance obligation. Revenue is recognized over time for maintenance plans provided to customers that provide services beyond the Company’s standard warranty period. Payment terms between customers related to product sales vary by the type of customer, country of sale, and the products or services offered and could result in an unbilled receivable or deferred revenue balance depending on whether the performance obligation has been satisfied (or partially satisfied). For product sales to distributors, the Company recognizes revenue for both equipment and disposables upon shipment to distributors, which is when its performance obligations are complete. The Company's standard contracts with its distributors state that title to the equipment passes to the distributors at point of shipment to a distributor’s location. The distributors are responsible for shipment to the end customer along with any installation, training and acceptance of the equipment by the end customer. Payments from distributors are not contingent upon resale of the product. The Company also places equipment at customer sites. While the Company retains ownership of this equipment, the customer has the right to use it for a period of time provided they meet certain agreed to conditions. The Company recovers the cost of providing the equipment from the sale of its disposables. Software and Other Revenues To a lesser extent, the Company enters into other types of contracts including certain software licensing arrangements to provide software solutions to support its plasma, blood collection and hospital customers. A portion of its software sales are perpetual licenses typically accompanied by significant implementation services related to software customization as well as other professional and technical services. The Company generally recognizes revenue from the sale of perpetual licenses and related customization services over time (the Company is creating or enhancing an asset that the customer controls) using an input method which requires it to make estimates of the extent of progress toward completion of the contract. When the Company provides other services, including in some instances hosting, technical support and maintenance, it recognizes these fees and charges over time (the customer simultaneously receives and consumes benefits), as performance obligations for these services are satisfied during the contract period. Certain of its software licensing arrangements are term-based licenses that include a per-collection or a usage-based fee related to the use of the license and the related technical support and hosting services. For these usage-based arrangements, the Company applies the revenue recognition exception resulting in revenue recognition occurring upon the later of actual usage or satisfaction of the related performance obligations. The payment terms for software licensing arrangements vary by customer pursuant to the terms set forth in the customer contract and result in an unbilled receivable or deferred revenue balance depending on whether the performance obligation has been satisfied (or partially satisfied). Significant Judgments Revenues from product sales are recorded at the net sales price, which includes estimates of variable consideration related to rebates, product returns and volume discounts. These reserves are based on estimates of the amounts earned or to be claimed on the related sales. The Company's estimates take into consideration historical experience, current contractual and statutory requirements, specific known market events and trends, industry data, and forecasted customer buying and payment patterns. Overall, these reserves reflect the Company’s best estimates of the amount of consideration to which it is entitled based on the terms of the contract. The amount of variable consideration included in the net sales price is limited to the amount that is probable not to result in a significant reversal in the amount of the cumulative revenue recognized in a future period. Revenue recognized in the current period related to performance obligations satisfied in prior periods was not material. Contract Balances The timing of revenue recognition, billings and cash collections result in billed accounts receivable, unbilled receivables (contract assets), and customer advances and deposits (contract liabilities) on the consolidated balance sheets. The difference in timing between billing and revenue recognition primarily occurs in software licensing arrangements, resulting in contract assets and contract liabilities. As of September 29, 2018 and April 1, 2018, the Company had contract assets of $5.2 million and $2.7 million, respectively. The change is primarily due to the delay in billings compared to the revenue recognized. Contract assets are classified as other current assets and other long-term assets on the consolidated balance sheet. As of September 29, 2018 and April 1, 2018, the Company had contract liabilities of $16.4 million and $16.6 million, respectively. During the three and six months ended September 29, 2018, the Company recognized $4.1 million and $11.5 million, respectively, of revenue that was included in the above April 1, 2018 contract liability balance. Contract liabilities are classified as other current liabilities and other long-term liabilities on the consolidated balance sheet. Practical Expedients The Company elected not to disclose the value of transaction price allocated to unsatisfied performance obligations for contracts with an original expected length of one year or less. When applicable, the Company has also elected to use the practical expedient to not adjust the promised amount of consideration for the effects of a significant financing component if it is expected, at contract inception, that the period between when the Company transfers a promised good or service to a customer, and when the customer pays for that good or service, will be one year or less.
