THE BOEING COMPANY: ENVIRONMENTAL MITIGATION COSTS

Following the decision to expand its Everett, Washington facility for the 777 program, Boeing was required by the City of Everett to pay over $50 million in environmental and social mitigation costs. These requirements, mandated under the Washington State Environmental Policy Act (SEPA), included $47.46 million for off-site transportation improvements, as well as site-wide erosion control, wetland replacement, and low-income housing investments. The case highlights a conflict between Boeing's management accountants, who argued for expensing the costs as they added no measurable value to assets, and external auditors and tax groups, who argued for capitalization because the payments were a direct condition for obtaining necessary construction permits.

• The City of Everett required Boeing to pay for mitigation of environmental and social impacts as a condition for expanding its 777 production facility, with total off-site transportation mitigation costs for Boeing totaling $47.46 million.
• Under the Washington State Environmental Policy Act (SEPA), Boeing was required to prepare an environmental impact statement (EIS) to disclose and consider environmental impacts before permits were issued.
• Specific mitigation requirements included replacing destroyed wetlands at a ratio of three acres for every acre lost, protecting yew trees for medical research, and investing $2 million in a low-income housing tax credit program.
• Boeing's management accountants argued that mitigation costs should be expensed because they were not a predictable part of capital asset costs and did not add measurable value to the assets.
• External auditors from Deloitte & Touche recommended capitalizing the mitigation costs, asserting that they were direct costs of the project since they were essential for obtaining the permits to proceed.
• Boeing's tax group concluded that the company was required to capitalize the mitigation costs for tax purposes because the expenditures were capital in nature and provided economic benefits to Boeing beyond those available to the general public.
