Investments in debt securities with original maturities of greater than six months consist primarily of AAA and AA rated financial instruments and counterparties. The Company's investments are primarily in direct obligations of the U.S. government or its agencies, corporate bonds, and municipal bonds.</span></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"> </span></div><div style="line-height:120%;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">Concentrations of credit risk with respect to accounts receivable are generally not significant due to the diversity of the Company's customers and geographic sales areas. The Company sells its products primarily to OEMs and distributors in the Americas, Europe and Asia. The Company performs ongoing credit evaluations of its customers' financial condition and, as deemed necessary, may require collateral, primarily letters of credit.</span></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"> </span></div><div style="line-height:120%;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">Distributor advances in the consolidated balance sheets, totaled </span><span style="font-family:inherit;font-size:10pt;"><span>$170.7 million</span></span><span style="font-family:inherit;font-size:10pt;"> and </span><span style="font-family:inherit;font-size:10pt;"><span>$203.9 million</span></span><span style="font-family:inherit;font-size:10pt;"> at </span><span style="font-family:inherit;font-size:10pt;">March 31, 2019</span><span style="font-family:inherit;font-size:10pt;"> and March 31, </span><span style="font-family:inherit;font-size:10pt;">2018</span><span style="font-family:inherit;font-size:10pt;">, respectively. On sales to distributors, the Company's payment terms generally require the distributor to settle amounts owed to the Company for an amount in excess of their ultimate cost. The Company's sales price to its distributors may be higher than the amount that the distributors will ultimately owe the Company because distributors often negotiate price </span></div><div style="line-height:120%;text-align:left;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">reductions after purchasing the products from the Company and such reductions are often significant. It is the Company's practice to apply these negotiated price discounts to future purchases, requiring the distributor to settle receivable balances, on a current basis, generally within </span><span style="font-family:inherit;font-size:10pt;"><span>30</span></span><span style="font-family:inherit;font-size:10pt;"> days, for amounts originally invoiced. This practice has an adverse impact on the working capital of the Company's distributors. As such, the Company has entered into agreements with certain distributors whereby it advances cash to the distributors to reduce the distributors' working capital requirements. These advances are reconciled at least on a quarterly basis and are estimated based on the amount of ending inventory as reported by the distributor multiplied by a negotiated percentage. Such advances have no impact on revenue recognition or the Company's consolidated statements of income. The Company processes discounts taken by distributors against its deferred income on shipments to distributors' balance and trues-up the advanced amounts generally after the end of each completed fiscal quarter. The terms of these advances are set forth in binding legal agreements and are unsecured, bear no interest on unsettled balances and are due upon demand. The agreements governing these advances can be canceled by the Company at any time.</span></div>

Additionally, the Company is involved in a limited number of legal actions, both as plaintiff and defendant. Consequently, the Company could incur uninsured liability in any of those actions. The Company also periodically receives notifications from various third parties alleging infringement of patents or other intellectual property rights, or from customers requesting reimbursement for various costs. With respect to pending legal actions to which the Company is a party and other claims, although the outcomes are generally not determinable, the Company believes that the ultimate resolution of these matters will not have a material adverse effect on its financial position, cash flows or results of operations. Litigation and disputes relating to the semiconductor industry are not uncommon, and the Company is, from time </span></div><div style="line-height:120%;text-align:left;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">to time, subject to such litigation and disputes. As a result, no assurances can be given with respect to the extent or outcome of any such litigation or disputes in the future. </span></div><div style="line-height:120%;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">In connection with its acquisition of Microsemi, which closed on May 29, 2018, the Company became involved with the following legal matters:</span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;font-style:italic;">Federal Shareholder Class Action Litigation</span><span style="font-family:inherit;font-size:10pt;">.

On November 13, 2018, the Maknissian complaint was voluntarily dismissed. The Jackson complaint is allegedly brought on behalf of a putative class of purchasers of Microchip common stock between March 2, 2018 and August 9, 2018. The complaint asserts claims for alleged violations of the federal securities laws and generally alleges that the defendants issued materially false and misleading statements and failed to disclose material adverse facts about the Company’s business, operations, and prospects during the putative class period. The complaint seeks, among other things, compensatory damages and attorneys’ fees and costs on behalf of the putative class. On December 11, 2018, the Court issued an order appointing the lead plaintiff. An amended complaint was filed on February 22, 2019. Defendants filed a motion to dismiss the amended complaint on April 1, 2019.</span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;font-style:italic;">Federal Derivative Litigation.</span><span style="font-family:inherit;font-size:10pt;"> On December 17, 2018, a shareholder derivative lawsuit was filed against certain of the Company’s officers and directors in the United States District Court for the District of Arizona, captioned Kistenmacher v.

The complaint generally alleges that defendants breached their fiduciary duties by, among other things, making or causing the Company to make false and misleading statements and omissions regarding the Microsemi acquisition, the Company’s business, operations, and prospects, and a purported failure to maintain internal controls. The complaint further alleges that certain defendants engaged in insider trading. The complaint asserts causes of action for alleged violations of Section 14(a) of the Securities Exchange Act, breach of fiduciary duties, and unjust enrichment and seeks unspecified monetary damages, corporate governance reforms, restitution, and attorneys’ fees and costs. </span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;font-style:italic;">State Derivative Litigation.</span><span style="font-family:inherit;font-size:10pt;"> On January 22, 2019, a shareholder derivative lawsuit was filed against certain of the Company’s officers and directors in the Superior Court of Arizona for Maricopa County, captioned Reid v.

The complaint generally alleges that defendants breached their fiduciary duties by, among other things, purportedly failing to conduct adequate due diligence regarding Microsemi prior to its acquisition, misrepresenting the Company’s business prospects and health, and engaging in improper practices, and further alleges that certain defendants engaged in insider trading. The complaint asserts causes of action for breach of fiduciary duty, waste, and unjust enrichment and seeks unspecified monetary damages, corporate governance reforms, equitable and/or injunctive relief, restitution, and attorneys’ fees and costs.

On November 8, 2018, defendants removed the action to the United States District Court for the Central District of California, Case No. 18-cv-02000-JLS. Defendants moved to dismiss, and, following the Court's ruling, Plaintiffs filed an amended complaint that dropped the trade libel and UCL claims. The plaintiffs are seeking unspecified compensatory damages (ranging from an alleged </span><span style="font-family:inherit;font-size:10pt;"><span>$10 million</span></span><span style="font-family:inherit;font-size:10pt;"> to </span><span style="font-family:inherit;font-size:10pt;"><span>$100 million</span></span><span style="font-family:inherit;font-size:10pt;">), as well as punitive damages, injunctive relief, and attorneys' fees and costs.

The Request alleges that a quality issue affecting Continental airbag control units in certain recalled vehicles stems from allegedly defective Atmel application specific integrated circuits ("ASICs"). Continental seeks to recover from Atmel all related costs and damages incurred as a result of the vehicle manufacturers’ airbag control unit-related recalls, currently alleged to be </span><span style="font-family:inherit;font-size:10pt;"><span>$208 million</span></span><span style="font-family:inherit;font-size:10pt;">. The Company's Atmel subsidiaries intend to defend this action vigorously.</span></div><div style="line-height:120%;padding-bottom:13px;text-align:left;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;font-style:italic;">Southern District of New York Action by LFoundry Rousset ("LFR") and LFR Employees</span><span style="font-family:inherit;font-size:10pt;">. On March 4, 2014, LFR and Jean-Yves Guerrini, individually and on behalf of a putative class of LFR employees, filed an action in the United States District Court for the Southern District of New York (the "District Court") against the Company's Atmel subsidiary, French subsidiary, Atmel Rousset S.A.S. ("Atmel Rousset"), and LFoundry GmbH ("LF"), LFR's German parent. The case purports to relate to Atmel Rousset's June 2010 sale of its wafer manufacturing facility in Rousset, France to LF, and LFR's subsequent insolvency, and later liquidation, more than three years later. The District Court dismissed the case on August 21, 2015, and the United States Court of Appeals for the Second Circuit affirmed the dismissal on June 27, 2016. On July 25, 2016, the plaintiffs filed a notice of appeal from the District Court's June 27, 2016 denial of their motion for relief from the dismissal judgment. On May 19, 2017, the United States Court of Appeals for the Second Circuit affirmed the June 27, 2016 order dismissing the case.</span></div><div style="line-height:120%;padding-bottom:13px;text-align:left;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;font-style:italic;">Individual Labor Actions by former LFR Employees</span><span style="font-family:inherit;font-size:10pt;">. In June 2010, Atmel Rousset sold its wafer manufacturing business in Rousset, France to LFoundry GmbH ("LF"), the German parent of LFoundry Rousset ("LFR"). LFR then leased the Atmel Rousset facility to conduct the manufacture of wafers. More than three years later, LFR</span><span style="font-family:inherit;font-size:10pt;font-style:italic;"> </span><span style="font-family:inherit;font-size:10pt;">became insolvent and later liquidated. In the wake of LFR's insolvency and liquidation, over </span><span style="font-family:inherit;font-size:10pt;">500</span><span style="font-family:inherit;font-size:10pt;"> former employees of LFR have filed individual labor actions against Atmel Rousset in a French labor court. The Company's Atmel Rousset subsidiary believes that each of these actions is entirely devoid of merit, and, further, that any assertion by any of the Claimants of a co-employment relationship with the Atmel Rousset subsidiary is based substantially on the same specious arguments that the Paris Commercial Court summarily rejected in 2014 in related proceedings. The Company's Atmel Rousset subsidiary therefore intends to defend vigorously against each of these claims. Additionally, complaints have been filed in a regional court in France on behalf of the same group of employees against Microchip Technology Rousset, Atmel Switzerland Sarl, Atmel Corporation and Microchip Technology Incorporated alleging that the sale of the Atmel Rousset production unit to LF was fraudulent and should be voided. Furthermore, new claims have been filed in a regional court in France on behalf of a subset of this same group of employees against Microchip Technology Incorporated and Atmel Corporation. These claims are specious and the defendant entities therefore intend to defend vigorously against these claims.</span></div><div style="line-height:120%;padding-bottom:13px;text-align:left;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">The Company accrues for claims and contingencies when losses become probable and reasonably estimable. As of the end of each applicable reporting period, the Company reviews each of its matters and, where it is probable that a liability has been or will be incurred, the Company accrues for all probable and reasonably estimable losses. Where the Company can reasonably estimate a range of losses it may incur regarding such a matter, the Company records an accrual for the amount within the range that constitutes its best estimate. If the Company can reasonably estimate a range but no amount within the range appears to be a better estimate than any other, the Company uses the amount that is the low end of such range. As of March 31, 2019, the Company's estimate of the aggregate potential liability that is possible but not probable is approximately </span><span style="font-family:inherit;font-size:10pt;"><span>$100 million</span></span><span style="font-family:inherit;font-size:10pt;"> in excess of amounts accrued. </span></div><div style="line-height:120%;padding-bottom:13px;text-align:left;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">The Company's technology license agreements generally include an indemnification clause that indemnifies the licensee against liability and damages (including legal defense costs) arising from any claims of patent, copyright, trademark or trade secret infringement by the Company's proprietary technology. The terms of these indemnification provisions approximate the terms of the outgoing technology license agreements, which are typically perpetual unless terminated by either party for breach. The possible amount of future payments the Company could be required to make based on agreements that specify indemnification limits, if such indemnifications were required on all of these agreements, is approximately </span><span style="font-family:inherit;font-size:10pt;"><span>$164 million</span></span><span style="font-family:inherit;font-size:10pt;">. There are some licensing agreements in place that do not specify indemnification limits. As of March 31, 2019, the Company had not recorded any liabilities related to these indemnification obligations and the Company believes that any amounts that it may be required to pay under these agreements in the future will not have a material adverse effect on its financial position, cash flows or results of operations.</span></div><div style="line-height:120%;padding-bottom:13px;text-align:left;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">The Company has learned of an ongoing compromise of its computer networks by what is believed to be sophisticated hackers. The Company has engaged experienced legal counsel and a leading forensic investigatory firm with experience in such matters. The Company has taken steps to identify malicious activity on its network including a compromise of its network and, as of the date of this filing, the Company is implementing a containment plan. The Company is continuing to evaluate the effectiveness of the containment plan and the amount and content of the information that was compromised and to implement additional remedial actions. At this time, the Company does not believe that this IT system compromise has had a material adverse effect on its business or resulted in any material damage to it. However, the Company is still evaluating the amount and type of data that was compromised and there can be no assurance as to what the impact of this IT system compromise will be. The Company has considered whether there may be litigation, investigations or claims related to such matter but it is too early to know if or whether litigation, investigations or claims may be asserted or what the nature of such proceedings or alleged damages may be.</span></div>
