These ASU’s require financial assets measured at amortized cost to be presented at the net amount to be collected and broadens the information, including forecasted information incorporating more timely information, that an entity must consider in developing its expected credit loss estimate for assets measured. These ASU’s are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early application is permitted for fiscal years beginning after December 15, 2018. Most of our financial assets are excluded from the requirements of this standard as they are measured at fair value or are subject to other accounting standards. In addition, certain of our other financial assets are short-term in nature and therefore are not likely to be subject to significant credit losses beyond what is already recorded under current accounting standards. As a result, we currently do not anticipate this standard to have a significant impact on our consolidated financial statements. </span></div><div style="text-indent:22.5pt;margin-top:6pt;"><span style="background-color:rgb(255,255,255, 0.0);color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;">In August 2018, the FASB issued ASU 2018-13, </span><span style="background-color:rgb(255,255,255, 0.0);color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%;">Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurements</span><span style="background-color:rgb(255,255,255, 0.0);color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;">, which amends FASB ASC Topic 820, </span><span style="background-color:rgb(255,255,255, 0.0);color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%;">Fair Value Measurements</span><span style="background-color:rgb(255,255,255, 0.0);color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;">.
