Section 8 – Other Events

Item 8.01.Other Events

In July 2017, Weyerhaeuser Company (the “Company”) announced it was implementing a solution to address concerns regarding its TJI® Joists with Flak Jacket® Protection. The Company recorded a $50 million pre-tax reserve for costs to remediate these concerns in second quarter 2017.

As remediation work has progressed, the Company has obtained additional experience and information about the scope of the required remediation efforts and associated costs, and has also completed the process of identifying the population of affected homes. The Company now expects to record approximately $175 million to $200 million of additional pre-tax expense, primarily in third quarter 2017. The increase in estimated cost is attributable to a higher cost per home for remediation, a modest increase in the estimated number of homes affected, and additional homebuilder and homeowner reimbursements.

The Company expects a significant portion of the approximately $225 million to $250 million of total pre-tax expense will be covered by insurance.

As of September 13, 2017, remediation is complete or underway in nearly 1,500 of the approximately 2,500 affected houses, which are in various stages of construction.
