On an ongoing basis, we evaluate these estimates, including those related to reserves for accounts receivable; goodwill and other intangible assets; income taxes; inventory valuation; revenue recognition, product returns, customer programs and multiple element arrangements; share-based compensation; warranty reserves; self-insurance reserves; fair value measurements and loss contingencies. We accrue contingent liabilities when it is probable that future expenditures will be made and such expenditures can be reasonably estimated. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates.</span></div>

Since then, the FASB has issued an update to ASU 2016-13. The allowance for credit losses is a valuation account that is deducted from the amortized cost basis of the financial asset to present the net carrying value at the amount expected to be collected. The income statement reflects the measurement of credit losses for newly recognized financial assets, as well as the increases or decreases of expected credit losses that have taken place during the period. The measurement of expected credit losses is based upon historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. The amendments in this update are effective for fiscal years beginning after December 15, 2019 and interim periods within those annual periods. We do not anticipate any material impact related to our allowance for doubtful accounts or otherwise from this amendment on the consolidated financial statements. </span></div><div style="line-height:120%;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"> </span></div><div style="line-height:120%;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">In August 2018, the FASB issued ASU 2018-13, </span><span style="font-family:inherit;font-size:10pt;font-style:italic;">Fair Value Measurement (Topic 820): Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement</span><span style="font-family:inherit;font-size:10pt;"> ("ASU 2018-13"), which modifies the disclosure </span></div><div style="line-height:120%;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">requirements of fair value measurements.
