Estimates and judgments are based on historical experience, forecasted events, and various other assumptions that we believe to be reasonable under the circumstances. Estimates and judgments may differ under different assumptions or conditions. We evaluate our estimates and judgments on an ongoing basis. Actual results could differ from estimates.</span></div>

This ASU requires a convertible debt instrument to be accounted for as a single liability measured at its amortized cost, as long as no other features require bifurcation and recognition as derivatives. This ASU requires an entity to use the if-converted method in the diluted earnings per share calculation for convertible instruments. This ASU will be effective for us in the first quarter of 2023, with early adoption permitted beginning in the first quarter of 2022, and permits the use of either the modified retrospective or fully retrospective method of transition. We are evaluating the timing and effects of our adoption of this ASU on our financial statements.</span></div><div><span><br/></span></div><div><span style="background-color:rgb(255,255,255, 0.0);color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%;">In November 2018, the FASB issued ASU 2018-18 – </span><span style="background-color:rgb(255,255,255, 0.0);color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%;">Collaborative Arrangements</span><span style="background-color:rgb(255,255,255, 0.0);color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%;">, which clarifies that certain transactions between collaborative arrangement participants should be accounted for as revenue when the collaborative arrangement participant is a customer in the context of a unit of account and precludes recognizing as revenue consideration received from a collaborative arrangement participant if the participant is not a customer. This ASU is effective for us in the first quarter of 2021 and requires retrospective adoption to the date we adopted ASC 606, which was August 31, 2018, by recognizing a cumulative-effect adjustment to the opening balance of retained earnings of the earliest annual period presented. We do not anticipate the adoption of this ASU will have a significant impact on our financial statements.</span></div><div><span><br/></span></div><div><span style="background-color:rgb(255,255,255, 0.0);color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%;">In June 2016, the FASB issued ASU 2016-13 – </span><span style="background-color:rgb(255,255,255, 0.0);color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%;">Measurement of Credit Losses on Financial Instruments</span><span style="background-color:rgb(255,255,255, 0.0);color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%;">, which requires a financial asset (or a group of financial assets) measured on the basis of amortized cost to be presented at the net amount expected to be collected. This ASU requires that the income statement reflect the measurement of credit losses for newly recognized financial assets as well as the increases or decreases of expected credit losses that have taken place during the period. This ASU requires that credit losses of debt securities designated as available-for-sale be recorded through an allowance for credit losses and limits the credit loss to the amount by which fair value is below amortized cost. This ASU is effective for us in the first quarter of 2021 and requires modified retrospective adoption, with prospective adoption for debt securities for which an other-than-temporary impairment had been recognized before the effective date. We do not anticipate the adoption of this ASU will have a significant impact on our financial statements.</span></div>

(“Micron B.V.”), in the District Court of Munich, Civil Chamber. The complaint seeks to void, under Section 133 of the German Insolvency Act, a share purchase agreement between Micron B.V. and Qimonda signed in fall 2008, pursuant to which Micron B.V. purchased substantially all of Qimonda’s shares of Inotera (the “Inotera Shares”), representing approximately 18% of Inotera’s outstanding shares at that time, and seeks an order requiring us to re-transfer those shares to the Qimonda estate.

In addition, the court issued interlocutory judgments ordering, among other things: (1) that Micron B.V. transfer to the Qimonda estate the Inotera Shares still owned by Micron B.V. and pay to the Qimonda estate compensation in an amount to be specified for any Inotera Shares sold to third parties; and (2) that Micron B.V. pay the Qimonda estate as compensation an amount to be specified for benefits derived by Micron B.V. from ownership of the Inotera Shares. The interlocutory judgments had no immediate, enforceable effect and Micron, accordingly, has been able to continue to operate with full control of the Inotera Shares subject to further developments in the case. On April 17, 2014, Micron and Micron B.V. filed a notice of appeal with the German Appeals Court challenging the District Court’s decision. After opening briefs, the Appeals Court held a hearing on the matter on July 9, 2015, and thereafter appointed an independent expert to perform an evaluation of Dr. Jaffé’s claims that the amount Micron paid for Qimonda was less than fair market value. On January 25, 2018, the court-appointed expert issued a report concluding that the amount paid by Micron was within an acceptable fair-value range. The Appeals Court held a subsequent hearing on April 30, 2019, and on May 28, 2019, the Appeals Court remanded the case to the expert for supplemental expert opinion. On March 31, 2020, the expert presented a revised opinion to the Appeals Court which reaffirmed the earlier view that the amount paid by Micron was still within an acceptable range of fair value.</span></div><div><span><br/></span></div><div><span style="background-color:rgb(255,255,255, 0.0);color:#0090da;font-family:'Arial',sans-serif;font-size:12pt;font-weight:700;line-height:120%;">Antitrust Matters</span></div><div><span><br/></span></div><div><span style="background-color:rgb(255,255,255, 0.0);color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%;">On April 27, 2018, a complaint was filed against Micron and other DRAM suppliers in the U.S. District Court for the Northern District of California.

On October 28, 2019, the plaintiffs filed a consolidated amended complaint that purports to be on behalf of a nationwide class of indirect purchasers of DRAM products. The amended complaint asserts claims based on alleged price-fixing of DRAM products under federal and state law during the period from June 1, 2016 to at least February 1, 2018, and seeks treble monetary damages, costs, interest, attorneys’ fees, and other injunctive and equitable relief.</span></div><div><span><br/></span></div><div><span style="background-color:rgb(255,255,255, 0.0);color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%;">On June 26, 2018, a complaint was filed against Micron and other DRAM suppliers in the U.S. District Court for the Northern District of California.

The lawsuit purported to be brought on behalf of a class of purchasers of our stock during the period from June 22, 2018 through November 19, 2018. Subsequently two substantially similar cases were filed in the same court adding one of our former officers, Ernie Maddock, as a defendant and alleging a class action period from September 26, 2017 through November 19, 2018. The separate cases were joined, and a consolidated amended complaint was filed on June 15, 2019. The consolidated amended complaint alleged that defendants committed securities fraud through misrepresentations and omissions about purported anticompetitive behavior in the DRAM industry and sought compensatory and punitive damages, fees, interest, costs, and other appropriate relief. On October 2, 2019, the parties submitted a joint stipulation to dismiss the complaint.
