Financial report summary

Management Discussion
  • Net Sales. In 2020, Company net sales decreased by $170.7 million, or 9% compared to the prior year. Net sales for 2020 were negatively impacted by lower than forecasted global vehicle production rates for calendar year 2020, which were down 16% on a year over year basis. The reduction in global light vehicle production and the Company's sales was impacted primarily a result of the global shutdowns as a result of the COVID-19 pandemic, which primarily impacted the Company in the second quarter of 2020. Automotive net sales decreased as a result of an 11% decrease in automatic-dimming mirror shipments, from 42.9 million units in 2019 to 38.2 million units in 2020.
  • Other net sales decreased 17% to $40.0 million compared to the prior year, as dimmable aircraft window sales decreased 30% year over year and fire protection saw a decrease in net sales of 4% year over year. Dimmable aircraft window sales were impacted by production challenges the Company's customer faced.
  • Cost of Goods Sold. As a percentage of net sales, cost of goods sold increased from 63.0% in 2019 to 64.1% in 2020. The year over year decrease in the gross profit margin was primarily the result of the Company's inability to leverage fixed overhead during the second quarter of 2020 as a result of COVID-19 related shutdowns and decreases in demand, as well as annual customer price reductions, which were partially offset by improvements in product mix related to Full Display Mirror® as well as purchasing cost reductions and structural cost reductions. On a year over year basis, the inability to leverage fixed overhead and annual customer price reductions each had a negative impact of approximately 150 - 250 basis points on gross profit margin. Purchasing cost reductions, product mix improvements, and structural cost reductions each independently had a positive impact on gross profit margin on a period over period basis of approximately 50 - 100 basis points.
