components at our various locations, the scope, timing and duration of various government restrictions to address the COVID-19 pandemic could impact our internal supply chain. We have implemented certain policy changes to help support our employees impacted by COVID-19. These measures have and will continue to increase the cost of our operations but the magnitude and length of time of this impact is difficult to quantify at this time and may continue to be difficult to estimate in the future. If our sales are reduced for an extended period or if our production output falls because of government restrictions, we may be required to reduce payroll-related costs and other expenses in the future through layoffs or furloughs, even though we have not done so to date. We have not experienced significant supply disruption from third-party component suppliers. However, we continue to face some supply chain constraints primarily related to logistics, including available air cargo space and higher freight rates. Available cargo space on flights between the U.S. and Europe, and Europe and Asia has been and remains limited as a result of the impact from COVID-19 and government and business responses to it, and this has increased shipping time and costs. In addition, shipments between countries have been more severely impacted by COVID-19 and we are experiencing delays due to additional checks at border crossings, including within Europe and Asia. There has also been sporadic restrictions on individual travel between certain states in the United States of America as well. Government actions related to COVID-19 come on the heels of increasing trade tensions between the United States and China, which may continue. We believe we have the ability to meet the near-term demand for our products, but the situation is fluid and subject to change. We continue to monitor the rapidly evolving conditions and circumstances as well as guidance from international and domestic authorities, including public health authorities, and we may need to take additional actions based on their recommendations. There is considerable uncertainty regarding the impact on our business stemming from current measures and potential future measures that could restrict access to our facilities, limit our manufacturing and support operations and place restrictions on our workforce, customers and suppliers. The measures implemented by various authorities related to the COVID-19 outbreak have caused us to change our business practices including those related to where employees work, the distance between employees in our facilities, limitations on in-person meetings between employees and with customers, suppliers, service providers, and stakeholders as well as restrictions on some shipping activities, business travel to domestic and international locations or to attend trade shows, investor conferences and other events. In March of 2020, we formed a COVID Steering Committee to, among other things, propose, discuss, and implement best practices in response to COVID-19. The COVID Steering Committee meets weekly and more often if required. All of our executive officers are members of the COVID Steering Committee as are many key senior-level employees. The COVID-19 pandemic has significantly increased worldwide and regional economic uncertainty and decreased demand for our products in many markets we serve, which could continue for an unknown period of time. In these circumstances, there may be developments outside of our control, including the length and extent of the COVID-19 outbreak, government-imposed measures and our ability to ship as well as install products and/or service installed products that may require us to adjust our operating plans. As such, given the dynamic nature of this situation, we cannot estimate with certainty the future impacts of COVID-19 on our financial condition, results of operations or cash flows. However, we do expect that it could have an adverse impact on our revenue as well as our overall profitability and may lead to an increase in inventory provisions, allowances for credit losses, and a volatile effective tax rate driven by changes in the mix of earnings across our markets. See the additional Risk Factor included in Part I-Item 1A of this annual report regarding the impact of COVID-19. Based on our internal projections and the preparation of our financial statements for the quarter ended April 4, 2020, and considering the forecasted decrease in demand due to the COVID-19 pandemic and other factors, we believed that the fair value of our ILS reporting unit might no longer have exceeded its carrying value and performed an interim goodwill impairment test on the ILS and OLS reporting units. Based on the estimated fair value of the ILS reporting unit, in the quarter ended April 4, 2020, we recorded non-cash pre-tax goodwill impairment charges of $327.2 million. In addition, we performed impairment tests on the long-lived assets allocated to the asset group of the ILS reporting unit, including intangible assets, property, plant and equipment and right of use ("ROU") assets as of April 4, 2020 and recorded non-cash pre-tax charges, in the quarter ended April 4, 2020, related to the impairment intangible assets, property, plant and equipment and ROU assets of the ILS reporting unit of $33.9 million, $85.6 million and $1.8 million, respectively. See Note 8, "Goodwill and Intangible Assets" and Note 11, "Leases" in the Notes to Consolidated Financial Statements under Item 8 of this annual report. In June 2019, we internally announced our plans to exit a portion of our High Power Fiber Laser ("HPFL") business and consolidate all HPFL manufacturing and engineering functions in our Tampere, Finland facility by transferring certain HPFL activities from our Hamburg, Germany facility. In conjunction with this announcement, we recorded restructuring charges in Restructuring Goodwill and other impairment charges 52
