(

) Revenue Recognition

We recognize revenues when obligations under the terms of a contract with our customers are satisfied, which generally occurs when products are shipped and control is transferred. We enter into contracts that pertain to products, which are accounted for as separate performance obligations and typically

one

year or less in duration. We do

not

exercise significant judgment in determining the timing for the satisfaction of performance obligations or the transaction price. Revenue is measured as the amount of consideration expected to be received in exchange for our products. We have elected to apply the practical expedient provided for in ASU

No.

and

not

disclose information regarding remaining performance obligations that have original expected durations of

one

year or less.

Variable consideration that

may

affect the total transaction price, including contractual discounts, rebates, returns and credits are included in net sales. Estimates for variable consideration are based on historical experience, anticipated performance and management's judgment and are updated as of each reporting date. Shipping and related expenses associated with outbound freight are accounted for as fulfillment costs and included in cost of sales. We do

not

have significant financing components.

Contract assets primarily relate to our rights to consideration for products that are delivered but

not

billed as of the reporting date and are reclassified to receivables when the customer is invoiced. Contract liabilities primarily relate to performance obligations that are to be satisfied in the future and arise when we bill the customer in advance of shipments. Contract costs are

not

significant and are recognized as incurred. Contract assets and liabilities were

not

material as of

March

30,

2019.

Accounts receivable includes amounts billed and currently due from customers stated at their net estimated realizable value. Customer payment terms are generally

days. We maintain an allowance for doubtful accounts to provide for the estimated amount of receivables that will

not

be collected, which is based upon our assessment of customer creditworthiness, historical payment experience and the age of outstanding receivables. Past-due trade receivable balances are written off when our collection efforts have been unsuccessful.
