NOTE 9  Commitments and Contingencies Purchase commitments  As of June 30, 2020, we had approximately $26.8 million in non-cancelable purchase contracts related to capital expenditures, primarily related to our manufacturing facilities in Asia. As of June 30, 2020, we also had a commitment to purchase approximately $29.8 million of wafers to be used in our manufacturing process. These wafer purchases will occur during 2020. Defined Benefit Plan - We have a contributory defined benefit plan that covers certain employees in the United Kingdom. As of June 30, 2020, the unfunded liability for this defined benefit plan was approximately $28.7 million. An actuarial valuation was performed as of March 31, 2019, resulting in a deficit of approximately GBP 26.7 million (approximately $27.9 million based on a GBP: USD exchange rate of 1.2:1). As a result of this valuation we have agreed to a revised schedule of contributions of GBP 2.0 million (approximately $2.4 million based on a GBP: USD exchange rate of 1.2:1) to be paid in annual installments with effect from April 1, 2020 to address the deficit revealed by the valuation (with the first payment made by March 31, 2021, and payments to be made by December 31 each year thereafter). These contributions, together with the assumed asset outperformance, are expected to eliminate the deficit by December 31, 2028. Further, we will pay GBP 0.2 million in annual installments effective April 1, 2020 to cover expenses. Contingencies  From time to time, we are involved in various legal proceedings that arise in the normal course of business. While we intend to defend any lawsuit vigorously, we presently believe that the ultimate outcome of any pending legal proceeding will not have any material adverse effect on our consolidated financial position, cash flows or operating results. However, litigation is subject to inherent uncertainties, and unfavorable rulings could occur. An unfavorable ruling could include monetary damages, which could impact our business and operating results for the period in which the ruling occurs or future periods. Based on information available, we evaluate the likelihood of potential outcomes of all pending disputes. We record an appropriate liability when the amount of any liability associated with a pending dispute is deemed probable and reasonably estimable. In addition, we do not accrue for estimated legal fees and other directly related costs as they are expensed as incurred. The Company is not currently a party to any pending litigation that the Company considers material.
