Revenue

On April 2, 2018, we adopted ASU 2014-09 using the modified retrospective method applied to those contracts which were not completed as of April 2, 2018. Results for reporting periods beginning after April 2, 2018 are presented under ASU 2014-09, while prior period amounts are not adjusted and continue to be reported in accordance with historic accounting under Accounting Standards Codification (“ASC”) Topic 605.

Our revenue arrangements generally consist of a single performance obligation to transfer promised goods or services. As a result, the application of ASU 2014-09 had no impact on our financial statement line items as compared with the guidance that was in effect before the change. Accordingly, the impact of adopting the standard resulted in no adjustment to accumulated retained earnings.

We disaggregate revenues from contracts with customers by both operating segments and types of product sold. Reporting by operating segment is pertinent to understanding our revenues, as it aligns to how we review the financial performance of our operations. Types of products sold within each operating segment help us to further evaluate the financial performance of our segments.

The following table disaggregates external customer net sales by major revenue stream for the three months ended July 1, 2018:

(1)

For our Industrial and Water Treatment segments, this line includes our bulk products that we do not modify in any way, but receive, store, and ship from our facilities, or direct ship to our customers in large quantities. For our Health and Nutrition segment, this line includes our non-manufactured distributed specialty products, which may be sold out of one of our facilities or direct shipped to our customers.


(2)	For our Industrial and Water Treatment segments, this line includes our non-bulk specialty products that we either manufacture, blend, repackage, resell in their original form, or direct ship to our customers in smaller quantities. For our Health and Nutrition segments, this line includes products manufactured in our facility.

Net sales include products and shipping charges, net of estimates for product returns and any related sales rebates. Revenue is measured as the amount of consideration we expect to receive in exchange for transferring products. All revenue is recognized when we satisfy our performance obligations under the contract. Our criteria for recording revenue is consistent between our operating segments and types of products sold. We recognize revenue upon transfer of control of the promised products to the customer, with revenue recognized at the point in time the customer obtains control of the products. In arrangements where product is shipped directly from the vendor to our customer, we act as the principal in the transaction as we direct the other party to provide the product to our customer on our behalf, take inventory risk, establish the selling price, and are exposed to credit risk for the collection of the invoiced amount. If there were circumstances where we were to manufacture products for customers that were unique to their specifications and we would be prohibited by contract to use the product for any alternate use, we would recognize revenue over time if all criteria were met. We have made a policy election to treat shipping costs for FOB shipping point sales as fulfillment costs. As such, we recognize revenue for all shipping charges, if applicable, at the same time we recognize revenue on the products delivered. We estimate product returns based on historical return rates. Using probability assessments, we estimate sales rebates expected to be paid over the term of the contract. The majority of our contracts have a single performance obligation and are short term in nature. Sales taxes that are collected from customers and remitted to governmental authorities are accounted for on a net basis and therefore are excluded from net sales. We offer certain customers cash discounts and volume rebates as sales incentives. The discounts and volume rebates are recorded as a reduction in sales at the time revenue is recognized in an amount estimated based on historical experience and contractual obligations. We periodically review the assumptions underlying our estimates of discounts and volume rebates and adjusts its revenues accordingly.
