The guidance requires that financial assets measured at amortized cost be presented at the net amount expected to be collected. The allowance for credit losses is a valuation account that is deducted from the amortized cost basis. The income statement reflects the measurement of credit losses for newly recognized financial assets, as well as the expected credit losses during the period. The measurement of expected credit losses is based upon historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. Credit losses relating to available-for-sale debt securities will be recorded through an allowance for credit losses rather than as a direct write-down to the security. The updated guidance is effective for annual periods beginning after December 15, 2019, and is applicable to the Company in fiscal 2021. Early adoption is permitted. The Company is currently evaluating the impact of the adoption of ASU 2016-13, as well as all codification improvements in ASU 2019-04, ASU 2019-10, ASU 2019-11 and ASU 2020-03, on its consolidated financial position and results of operations.</span></div><div style="text-indent:22.5pt;"><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%;"> </span></div><div style="text-indent:22.5pt;"><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 November 2019, the FASB issued ASU No. 2019-08, </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%;">Compensation - Stock Compensation (Topic 718) and Revenue from Contracts with Customers (Topic 606)</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%;">. The guidance identifies, evaluates, and improves areas of GAAP for which cost and complexity can be reduced while maintaining or improving the usefulness of the information provided. The amendments in that Update expanded the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from nonemployees. For entities that have adopted the amendments in Update 2018-07, the updated guidance is effective for annual periods beginning after December 15, 2019, and is applicable to the Company in fiscal 2021.

The Board is issuing this Update to clarify certain interactions between the guidance to account for certain equity securities under Topic 321, the guidance to account for </span></div>investments under the equity method of accounting in Topic 323, and the guidance in Topic 815. This update could change how an entity accounts for an equity security under the measurement alternative or a forward contract or purchased option to purchase securities that, upon settlement of the forward contract or exercise of the purchased option, would be accounted for under the equity method of accounting or the fair value option in accordance with Topic 825, Financial Instruments.
