Actual results could differ from those estimates.</span></div>
	us-gaap	Description Of New Accounting Pronouncements Not Yet Adopted DescriptionOfNewAccountingPronouncementsNotYetAdopted	<div style="line-height:120%;text-indent:36px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">In June 2016, the FASB issued ASU No. 2016-13, </span><span style="font-family:inherit;font-size:10pt;font-style:italic;">Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments</span><span style="font-family:inherit;font-size:10pt;">, to replace the incurred loss methodology with an expected credit loss model that requires consideration of a broader range of information to estimate credit losses over the lifetime of the asset. An entity with trade receivables will be required to use historical loss information, current conditions, and reasonable and supportable forecasts to determine expected credit losses. Pooling of assets with similar risk characteristics and the use of a loss model are also required. Also, in April 2019, the FASB issued ASU No. 2019-04, </span><span style="font-family:inherit;font-size:10pt;font-style:italic;">Codification Improvements to Topic 326, Financial Instruments—Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments, </span><span style="font-family:inherit;font-size:10pt;">to clarify the inclusion of recoveries of trade receivables previously written off when estimating an allowance for credit losses. The amendments in this update are effective for the Company beginning with fiscal year 2020, including interim periods, with early adoption permitted as of the fiscal years beginning after December 31, 2018, including interim periods within those fiscal years. The adoption of the amendments in this update is not expected to have a material impact on the Company’s consolidated financial position and results of operations.</span></div><div style="line-height:120%;text-indent:36px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-indent:36px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">In January 2017, the FASB issued ASU No. 2017-04, </span><span style="font-family:inherit;font-size:10pt;font-style:italic;">Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment</span><span style="font-family:inherit;font-size:10pt;">, to simplify the subsequent measurement of goodwill by eliminating Step 2 from the goodwill impairment test. An entity no longer will determine goodwill impairment by calculating the implied fair value of goodwill by assigning the fair value of a reporting unit to all of its assets and liabilities as if the reporting unit had been acquired in a business combination. Instead, under the amendments in this update, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. The Board also eliminated the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment and, if it fails that qualitative test, to perform Step 2 of the goodwill impairment test. The amendments in this update are effective for the Company beginning with fiscal year 2020, including interim periods, with early adoption permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017.
