The Company repurchased $151,546, $19,366, and $538,444, principal amounts of convertible debt instruments and recognized losses on early extinguishment of the repurchased convertible debt of $8,073, $2,030, and $26,583 in 2020, 2019, and 2018, respectively.

Impact of the Coronavirus Outbreak

The Company's operations have been impacted by the coronavirus ("COVID-19") outbreak.  Some manufacturing facilities were temporarily closed and some are operating at levels less than full capacity.  The Company has incurred incremental costs separable from normal operations that are directly related to the outbreak and containment efforts, primarily wages paid to manufacturing employees during government-mandated shut-downs, additional wages and hardship allowances for working during lockdown periods, additional costs of cleaning and disinfecting facilities, costs of additional safety equipment for employees, and temporary housing for employees due to travel restrictions, which were partially offset by government subsidies.  The net impact of the costs and subsidies are reported as cost of products sold of $4,563 and selling, general, and administrative benefits of $1,451 based on employee function on the consolidated statement of operations for the year ended December 31, 2020.

The Company's insurance coverages generally exclude losses incurred due to pandemics.  Any amounts that may be received will not be recognized until all contingencies are settled.
