Costs Associated with Exit or Disposal Activities.   On April 27, 2020, Packaging Corporation of America approved and announced to affected employees a plan for the closure of its corrugated products production facility located in San Lorenzo, California. The San Lorenzo facility was acquired as part of the Boise acquisition in 2013 and was part of the Tharco stock box business. The majority of the plant’s equipment will be transferred to other PCA facilities and approximately 20% of the San Lorenzo customer business will be absorbed into other PCA plants. The last date of production at the plant is expected to be in June 2020. The closure is estimated to result in pre-tax: (1) total cash severance and other cash shutdown costs of approximately $14 to $18 million; and (2) total non-cash charges of approximately $9 to $13 million, which are primarily asset impairment and accelerated depreciation charges. PCA expects to record $21 to $25 million of charges in the second quarter of 2020.   Item 9.01.
