Subsequent to the issuance of ASU 2016-13, ASC 326 was amended by various updates that amend and clarify the impact and implementation of the aforementioned update. The new guidance introduces the current expected credit loss (“CECL”) model, which requires an entity to record an allowance for credit losses for certain financial instruments and financial assets, including trade receivables, based on expected losses rather than incurred losses. Under this update, on initial recognition and at each reporting period, an entity is required to recognize an allowance that reflects the entity’s current estimate of credit losses expected to be incurred over the life of the financial instrument. In February 2020, the FASB issued ASU No. 2020-02, </span><span style="font-family:Arial Narrow;font-size:10pt;color:#000000;font-style:italic;">Financial Instruments-Credit Losses (Topic 326) and Leases (Topic 842)-Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 119 and Update to SEC Section on Effective Date Related to Accounting Standards Update No. 2016-02, Leases (Topic 842) </span><span style="font-family:Arial Narrow;font-size:10pt;color:#000000;">(“ASU 2020-02”), which amended the language in Subtopic 326-20 and addressed questions primarily regarding documentation and company policies. ASU 2016-13 and its amendments are effective for the Company for interim and annual periods in fiscal years beginning after December 15, 2019, on a modified retrospective basis. The adoption of ASU 2016-13 and its amendments on January 1, 2020 did not have a material impact on the Company’s</span><span style="font-family:Arial Narrow;font-size:10pt;color:#000000;"> Condensed </span><span style="font-family:Arial Narrow;font-size:10pt;color:#000000;">Consolidated Financial Statements and related disclosures. </span><span style="font-family:Arial Narrow;font-size:10pt;color:#000000;">The Company will continue to actively monitor the impact of the recent COVID-19 pandemic, and </span><span style="font-family:Arial Narrow;font-size:10pt;color:#000000;">the impact on our customers due to the reduced demand for oil and gas, as well as the oversupply of oil,</span><span style="font-family:Arial Narrow;font-size:10pt;color:#000000;"> on expected credit losses.</span></div><div style="line-height:120%;padding-left:0px;text-indent:36px;font-size:10pt;"><span style="font-family:Arial Narrow;font-size:10pt;"><br/></span></div><div style="line-height:120%;padding-left:0px;text-indent:36px;font-size:10pt;"><span style="font-family:Arial Narrow;font-size:10pt;color:#000000;">In March 2020, the FASB issued ASU No. 2020-03, </span><span style="font-family:Arial Narrow;font-size:10pt;color:#000000;font-style:italic;">Codification Improvements to Financial Instruments</span><span style="font-family:Arial Narrow;font-size:10pt;color:#000000;"> (“ASU 2020-03”).

ASU 2020-03 included seven different issues that describe the areas of improvement and the related amendments to GAAP, intended to make the standards easier to understand and apply by eliminating inconsistencies and providing clarifications.

Entities may apply the provisions of the new standard as of the beginning of the reporting period when the election is made (i.e., as early as the first quarter of 2020). Unlike other topics, the provisions of this update are only available until December 31, 2022, when the reference rate replacement activity is expected to have been completed. The Company is currently evaluating the impact of the provisions of ASU 2020-04 on its financial condition, results of operation, and cash flows.</span></div>
