Those estimates could change, and as a result, actual results could differ materially from those estimates. For example, the Company records impairment losses on long-lived assets used in operations when events and circumstances indicate that long-lived assets might be impaired and the undiscounted cash flows estimated to be generated by those assets are less than the carrying amounts of those assets. The Company’s estimate of undiscounted cash flows, at </font><font style="font-family:inherit;font-size:10pt;">December 31, 2017</font><font style="font-family:inherit;font-size:10pt;"> and </font><font style="font-family:inherit;font-size:10pt;">2016</font><font style="font-family:inherit;font-size:10pt;"> indicated that such carrying amounts were expected to be recovered.

If such assets are considered to be impaired, the impairment recognized is measured as the amount by which the carrying amount of the assets exceeds the fair value of the assets. The evaluation of recoverability involves estimates of future operating cash flows based upon certain forecasted assumptions, including, but not limited to, revenue growth rates, gross profit margins, and operating expenses over the expected remaining useful life of the related asset.

These facts and circumstances validate that the delivered element has value on a stand-alone basis and should be considered a separate unit of accounting.</font></div><div style="line-height:120%;text-indent:36px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-indent:36px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Having established separate units of accounting, the Company then allocates amounts to each unit of accounting. With respect to products, the Company has established vendor specific objective evidence (“VSOE”) based on the price at which such products are sold separately without commissioning services. With respect to commissioning, the Company charges out its engineers for field visits to customers based on a stand-alone standard daily field service charge as well as a flat service rate for travel, if applicable. This has been determined to be the VSOE of the service based on stand-alone sales of other comparable professional services at consistent pricing.</font></div><div style="line-height:120%;text-indent:36px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-indent:36px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">The amount allocable to the delivered unit of account (in our case the product) is limited to the amount that is not contingent upon the delivery of additional items or meeting specified performance conditions.

For these contracts, consistent with industry practice, the Company’s customers typically require their suppliers, including Energy Recovery, to accept contractual holdback provisions (also referred to as a retention payment) whereby the final amounts due under the sales contract are remitted over extended periods of time or alternatively, stand-by letters of credit are issued to guarantee performance. These retention payments are generally 10% or less of the total contract amount and are due and payable when the customer is satisfied that certain specified product performance criteria have been met upon commissioning of the desalination plant, which may be up to 24 months from the date of product delivery as described further below.</font></div><div style="line-height:120%;text-indent:36px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-indent:36px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Under stand-alone MPD contracts, the usual payment arrangements are summarized as follows:</font></div><div style="line-height:120%;text-indent:36px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><table cellpadding="0" cellspacing="0" style="font-family:Times New Roman; font-size:10pt;"><tr><td style="width:60px;" rowspan="1" colspan="1"></td><td rowspan="1" colspan="1"></td></tr><tr><td style="vertical-align:top" rowspan="1" colspan="1"><div style="line-height:120%;font-size:10pt;padding-left:36px;"><font style="font-family:inherit;font-size:10pt;">•</font></div></td><td style="vertical-align:top;" rowspan="1" colspan="1"><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">an advance payment due upon execution of the contract, typically </font><font style="font-family:inherit;font-size:10pt;">10%</font><font style="font-family:inherit;font-size:10pt;"> to </font><font style="font-family:inherit;font-size:10pt;">20%</font><font style="font-family:inherit;font-size:10pt;"> of the total contract amount.

The fair value of RSUs and RS is based on the Company’s stock price on the date of grant. The fair value of stock options is calculated on the date of grant using the Black-Scholes option pricing model, which requires a number of complex assumptions including expected life, expected volatility, risk-free interest rate, and dividend yield. The estimation of awards that will ultimately vest requires judgment, and to the extent that actual results or updated estimates differ from our current estimates, such amounts are recorded as a cumulative adjustment in the period in which the estimates are revised.

In the ordinary course of business, there is inherent uncertainty in quantifying income tax positions. The Company assesses income tax positions and record tax benefits for all years subject to examination based upon the Company’s evaluation of the facts, circumstances, and information available at the reporting dates. For those tax positions where it is more likely than not that a tax benefit will be sustained, the Company records the largest amount of tax benefit with a greater than 50% likelihood of being realized upon ultimate settlement with a taxing authority that has full knowledge of all relevant information. For those income tax positions where it is not more likely than not that a tax benefit will be sustained, no tax benefit is recognized in the financial statements. When applicable, associated interest and penalties are recognized as a component of income tax expense.

Deferred income taxes are recorded on temporary differences using enacted tax rates in effect for the year in which the temporary differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all of the deferred tax assets will not be realized. Significant judgment is required in determining whether and to what extent any valuation allowance is needed on the Company’s deferred tax assets. In making such a determination, the Company considers all available positive and negative evidence including recent results of operations, scheduled reversals of deferred tax liabilities, projected future income, and available tax planning strategies.

Following the enactment of the </font><font style="font-family:inherit;font-size:10pt;">Tax Act</font><font style="font-family:inherit;font-size:10pt;">, the Securities and Exchange Commission (“SEC”) staff issued Staff Accounting Bulletin (“SAB”) No. 118, (“</font><font style="font-family:inherit;font-size:10pt;">SAB 118</font><font style="font-family:inherit;font-size:10pt;">”) which provides guidance on accounting for the tax effects of the </font><font style="font-family:inherit;font-size:10pt;">Tax Act</font><font style="font-family:inherit;font-size:10pt;">. </font><font style="font-family:inherit;font-size:10pt;">SAB 118</font><font style="font-family:inherit;font-size:10pt;"> provides a measurement period that should not extend beyond one year from the </font><font style="font-family:inherit;font-size:10pt;">Tax Act</font><font style="font-family:inherit;font-size:10pt;"> enactment date for companies to complete the accounting under ASC No. 740 (“</font><font style="font-family:inherit;font-size:10pt;">ASC 740</font><font style="font-family:inherit;font-size:10pt;">”), </font><font style="font-family:inherit;font-size:10pt;font-style:italic;">Income Taxes.</font><font style="font-family:inherit;font-size:10pt;"> In accordance with </font><font style="font-family:inherit;font-size:10pt;">SAB 118</font><font style="font-family:inherit;font-size:10pt;">, a company must reflect the income tax effects of those aspects of the </font><font style="font-family:inherit;font-size:10pt;">Tax Act</font><font style="font-family:inherit;font-size:10pt;"> for which the accounting under </font><font style="font-family:inherit;font-size:10pt;">ASC 740</font><font style="font-family:inherit;font-size:10pt;"> is complete. To the extent that a company’s accounting for certain income tax effects of the </font><font style="font-family:inherit;font-size:10pt;">Tax Act</font><font style="font-family:inherit;font-size:10pt;"> is incomplete but it is able to determine a reasonable estimate, it must record a provisional estimate in the financial statements. If a company cannot determine a provisional estimate to be included in the financial statements, it should continue to apply </font><font style="font-family:inherit;font-size:10pt;">ASC 740</font><font style="font-family:inherit;font-size:10pt;"> on the basis of the provisions of the tax law that were in effect immediately before the enactment of the </font><font style="font-family:inherit;font-size:10pt;">Tax Act</font><font style="font-family:inherit;font-size:10pt;">. At December 31, 2017, the Company determined that given the Company’s facts and circumstances, no provisional estimates were needed, and, therefore, the Company has booked </font><font style="font-family:inherit;font-size:10pt;">no</font><font style="font-family:inherit;font-size:10pt;"> provisional estimates as of December 31, 2017. See Note </font><font style="font-family:inherit;font-size:10pt;">9</font><font style="font-family:inherit;font-size:10pt;">,</font><font style="font-family:inherit;font-size:10pt;font-style:italic;"> </font><font style="font-family:inherit;font-size:10pt;">“</font><font style="font-family:inherit;font-size:10pt;">Income Taxes</font><font style="font-family:inherit;font-size:10pt;">,” for a discussion of the Company’s income tax accounting related to the </font><font style="font-family:inherit;font-size:10pt;">Tax Act</font><font style="font-family:inherit;font-size:10pt;">.</font></div><div style="line-height:120%;text-indent:36px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-indent:36px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">The Company’s operations are subject to income and transaction taxes in the U.S. and in foreign jurisdictions. Significant estimates and judgments are required in determining the Company’s worldwide provision for income taxes. Some of these estimates are based on interpretations of existing tax laws or regulations. The ultimate amount of tax liability may be uncertain as a result.</font></div></div>

Those estimates could change, and as a result, actual results could differ materially from those estimates. For example, the Company records impairment losses on long-lived assets used in operations when events and circumstances indicate that long-lived assets might be impaired and the undiscounted cash flows estimated to be generated by those assets are less than the carrying amounts of those assets. The Company’s estimate of undiscounted cash flows, at </font><font style="font-family:inherit;font-size:10pt;">December 31, 2017</font><font style="font-family:inherit;font-size:10pt;"> and </font><font style="font-family:inherit;font-size:10pt;">2016</font><font style="font-family:inherit;font-size:10pt;"> indicated that such carrying amounts were expected to be recovered. Nonetheless, it is possible that the estimate of undiscounted cash flows may change in the future resulting in the need to write down those assets to fair value.</font></div></div>
