During the first quarter of 2021, the Company incurred additional costs under our existing 2018 global strategic plan to realign manufacturing facilities globally. These charges were primarily related to the restructuring of our downhole tools business where we are exiting certain underperforming countries and markets and shifting from manufacturing in-house to a vendor sourcing model which resulted in non-cash inventory write downs of $19.3 million, severance charges of $2.7 million and other charges of $3.0 million, consisting of facilities-related restructuring charges and professional fees.

We incurred restructuring and other charges associated with the global strategic plan of $32.7 million during the three months ended March 31, 2020. Of these charges, inventory write-downs, severance charges, long-lived assets write-downs and other charges were $17.3 million, $8.4 million, $6.9 million and $0.1 million respectively, during the three months ended March 31, 2020. These charges are reflected as "Restructuring and other charges" in our condensed consolidated statements of income (loss).
