This guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. This ASU introduces a new impairment model known as the current expected credit loss model. The ASU requires a financial asset measured at amortized cost to be presented at the net amount expected to be collected. Previously, recognition of the full amount of credit losses was generally delayed until the loss was probable of occurring. We are currently assessing the effects this guidance may have on our financial statements.</span></div><div style="line-height:120%;text-align:left;font-size:10pt;"><span style="font-family:Calibri,sans-serif;font-size:10pt;"><br/></span></div><div style="line-height:120%;font-size:11pt;"><span style="font-family:Calibri,sans-serif;font-size:11pt;font-weight:bold;">Cloud Computing</span><span style="font-family:Calibri,sans-serif;font-size:11pt;"> </span></div><div style="line-height:120%;text-align:left;font-size:11pt;"><span style="font-family:Calibri,sans-serif;font-size:11pt;"><br/></span></div><div style="line-height:120%;text-align:left;font-size:10pt;"><span style="font-family:Calibri,sans-serif;font-size:10pt;">In August 2018, the FASB issued ASU 2018-15, Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract. The standard allows entities who are customers in hosting arrangements that are service contracts to apply the existing internal-use software guidance to determine which implementation costs to capitalize as an asset related to the service contract and which costs to expense. The guidance specifies classification for capitalizing implementation costs and related amortization expense within the financial statements and requires additional disclosures. The guidance will be effective for annual reporting periods, including interim reporting within those periods, beginning after December 15, 2019. Early adoption is permitted and can be applied either retrospectively or prospectively. We are currently evaluating the transition methods and the impact the adoption of this standard may have on our financial statements.</span></div><div style="line-height:120%;text-align:left;font-size:10pt;"><span style="font-family:Calibri,sans-serif;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-align:left;font-size:11pt;"><span style="font-family:Calibri,sans-serif;font-size:11pt;font-weight:bold;">Disclosure Requirements for Defined Benefit Plans</span></div><div style="line-height:120%;text-align:left;font-size:11pt;"><span style="font-family:Calibri,sans-serif;font-size:11pt;"><br/></span></div><div style="line-height:120%;text-align:left;font-size:10pt;"><span style="font-family:Calibri,sans-serif;font-size:10pt;">In August 2018, the FASB issued ASU 2018-14, Disclosure Framework: Changes to the Disclosure Requirements for Defined Benefit Plans. The pronouncement modifies the disclosure requirements for defined benefit pension and other postretirement benefit plans. The guidance removes disclosures that are no longer considered cost beneficial, clarifies the specific requirements of disclosures and adds disclosure requirements identified as relevant. The modifications affect annual period disclosures and must be applied on a retrospective basis to all periods presented. The guidance will be effective for annual reporting periods ending after December 15, 2020, with early adoption permitted. We are currently evaluating the effects of this pronouncement on our Notes to Consolidated Financial Statements.</span></div>
