These debt securities are classified as available for sale ("AFS"). Upon adoption of ASU 2019-04 and 2018-14, we expect to revise our impairment model for AFS debt securities by implementing an allowance approach instead of an 'other than temporary' impairment model. We have recorded balances for trade receivables that also fall within the scope of the standard. We are currently assessing our process of recording reserves for uncollectible receivables to evaluate whether significant changes to our policy will be necessary to comply with the current expected credit loss model. ASC 326 also defines additional presentation and disclosure requirements. We are currently reviewing the impact of these requirements on our disclosures related to credit in our Notes to Condensed Consolidated Financial Statements (unaudited). We are unable to reasonably estimate the quantitative impact of adoption on our Condensed Consolidated Financial Statements (unaudited).

ASU 2016-13 will require the use of an "expected loss" model for instruments measured at amortized cost. It will also require entities to record allowances for available-for-sale securities rather than impair the carrying amount of the securities. Subsequent improvements to the estimated credit losses of available-for-sale securities will be recognized immediately in earnings instead of over time as they are under historic guidance.</span></div></td></tr></table></div><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-align:center;font-size:10pt;"><div style="padding-left:0px;text-indent:0px;line-height:normal;padding-top:10px;"><table cellpadding="0" cellspacing="0" style="font-family:Times New Roman;font-size:10pt;margin-left:auto;margin-right:auto;width:100%;border-collapse:collapse;text-align:left;"><tr><td colspan="4"/></tr><tr><td style="width:20%;"/><td style="width:29%;"/><td style="width:19%;"/><td style="width:32%;"/></tr><tr><td style="vertical-align:bottom;padding-left:2px;padding-top:2px;padding-bottom:2px;padding-right:2px;border-bottom:1px solid #000000;"><div style="text-align:center;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">Standard</span></div></td><td style="vertical-align:bottom;padding-left:2px;padding-top:2px;padding-bottom:2px;padding-right:2px;border-bottom:1px solid #000000;"><div style="text-align:center;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">Description</span></div></td><td style="vertical-align:bottom;padding-left:2px;padding-top:2px;padding-bottom:2px;padding-right:2px;border-bottom:1px solid #000000;"><div style="text-align:center;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">Effective Date</span></div></td><td style="vertical-align:bottom;padding-left:2px;padding-top:2px;padding-bottom:2px;padding-right:2px;border-bottom:1px solid #000000;"><div style="text-align:center;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">Effect on the financial statements or other significant matters</span></div></td></tr><tr><td style="vertical-align:top;border-bottom:1px solid #000000;padding-left:2px;padding-top:2px;padding-bottom:2px;padding-right:2px;border-top:1px solid #000000;"><div style="text-align:left;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">ASU 2018-14, </span><span style="font-family:inherit;font-size:10pt;font-style:italic;">Compensation—Retirement Benefits—Defined Benefit Plans—General (Subtopic 715-20): Disclosure Framework—Changes to the Disclosure Requirements for Defined Benefit Plans</span></div></td><td style="vertical-align:top;border-bottom:1px solid #000000;padding-left:2px;padding-top:2px;padding-bottom:2px;padding-right:2px;border-top:1px solid #000000;"><div style="text-align:left;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">The pronouncement modifies the disclosure requirements for defined benefit pension or other postretirement benefit plans.
