Effective for the year ended December 31, 2018, the Company adopted ASU 2014-09, Revenue from Contracts with Customers (Topic 606), using the modified retrospective adoption method. There was no impact on the consolidated financial statements and no cumulative effect adjustment was recognized. Although most revenue recognition is governed by the new standard, the accommodations and rentals revenue continued to be guided by ASC 842 - Leases, discussed further below. The core principle of Topic 606 is that revenue is recognized when goods or services are transferred to customers in an amount that reflects consideration for which entitlement is expected in exchange for those goods or services.

ASU 2014-09 provides a five-step model for determining revenue recognition for arrangements that are within the scope of the standard: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) the entity satisfies a performance obligation. The Company only applies the five-step model to contracts when it is probable that we will collect the consideration the Company is entitled to in exchange for the goods or services the Company transfers to the customer.

The Company elected practical expedients (i) not to access whether immaterial promised goods or services are performance obligations, (ii) not to provide disclosures on remaining performance obligations for contracts that have an original expected duration of one year or less and (iii) to exclude transaction price taxes assessed by governmental authorities as revenue.

The following factors are applicable to all three of the Company’s segments for the first six months of 2019 and 2018, respectively:

In the Water Services and Water Infrastructure segments, performance obligations arise in connection with services provided to customers in accordance with contractual terms, in an amount the Company expects to collect. Services are generally sold based upon customer orders or contracts with customers that include fixed or determinable prices. Revenues are generated by services rendered and measured based on output generated, which is usually simultaneously received and consumed by customers at their job sites. As a multi-job site organization, contract terms, including pricing for the Company’s services, are negotiated on a job site level on a per-job basis. Most jobs completed in a short period of time, usually between one day and one month. Revenue is recognized as performance obligations are completed on a daily, hourly or per unit basis with unconditional rights to consideration for services rendered reflected as accounts receivable trade, net of allowance for doubtful accounts. In cases where a prepayment is received before the Company satisfies its performance obligations, a contract liability is recorded in accrued expenses and other current liabilities. Final billings generally occur once all of the proper approvals are obtained. No revenue is associated with mobilization or demobilization of personnel and equipment. Rather, mobilization and demobilization are factored into pricing for services. Billings and costs related to mobilization and demobilization is not material for customer

agreements that start in one period and end in another. As of June 30, 2019, the Company had two contracts in place lasting over a year.

In the Oilfield Chemicals segment, the typical performance obligation is to provide a specific quantity of chemicals to customers in accordance with the customer agreement in an amount the Company expects to collect. Products and services are generally sold based upon customer orders or contracts with customers that include fixed or determinable prices. Revenue is recognized as the customer takes title to chemical products in accordance with the agreement. Products may be provided to customers in packaging or delivered to the customers’ containers through a hose. In some cases, the customer takes title to the chemicals upon consumption from storage containers on their property, where the chemicals are considered inventory until customer usage. In cases where the Company delivers products and recognizes revenue before collecting payment, the Company usually has an unconditional right to payment reflected in accounts receivable trade, net of allowance for doubtful accounts. Customer returns are rare and immaterial and there were no in-process customer agreements as of June 30, 2019 lasting greater than one year.

The Company accounts for accommodations and rentals agreements as an operating lease. The Company recognizes revenue from renting equipment on a straight-line basis. Accommodations and rental contract periods are generally daily, weekly or monthly. The average lease term is less than three months and as of June 30, 2019, no rental agreements lasted more than a year.
