Commitments and Contingencies We are and may from time to time become involved in litigation and disputes arising in the ordinary course of business, such as actions related to injuries; property damage; handling, storage or disposal of vehicles; environmental laws and regulations; and other litigation incidental to the business. Management considers the likelihood of loss or the incurrence of a liability, as well as the ability to reasonably estimate the amount of loss, in determining loss contingencies. We accrue an estimated loss contingency when it is probable that a liability has been incurred and the amount of loss (or range of possible losses) can be reasonably estimated. Management regularly evaluates current information available to determine whether accrual amounts should be adjusted. Accruals for contingencies, including litigation and environmental matters, are included in Other accrued expenses at undiscounted amounts and exclude claims for recoveries from insurance or other third parties. These accruals are adjusted periodically as assessment and remediation efforts progress, or as additional technical or legal information becomes available. If the amount of an actual loss is greater than the amount accrued, this could have an adverse impact on our operating results in that period. Such matters are generally not, in the opinion of management, likely to have a material adverse effect on our financial condition, results of operations or cash flows. Legal fees are expensed as incurred. There has been no significant change in the legal and regulatory proceedings which were disclosed in our audited consolidated financial statements for the fiscal year ended December 30, 2018 . IAALower Duwamish Waterway Since June 2004, IAA has operated a branch on property it leases in Tukwila, Washington just south of Seattle. The property is located adjacent to a Superfund site known as the Lower Duwamish Waterway Superfund Site ("LDW Site"). The LDW Site had been designated a Superfund site in 2001, three years prior to IAAs tenancy. On March 25, 2008, the United States Environmental Protection Agency (the "EPA") issued IAA a General Notice of Potential Liability, or "General Notice," pursuant to Section 107(a), and a Request for Information pursuant to Section 104(e) of the Comprehensive Environmental Response, Compensation, and Liability Act ("CERCLA") related to the LDW Site. On November 7, 2012, the EPA issued IAA a Second General Notice of Potential Liability (the "Second General Notice") for the LDW Site. The EPA's website indicates that the EPA has issued general notice letters to approximately 116 entities, and has issued Section 104(e) Requests to more than 300 entities related to the LDW Site. In the General Notice and Second General Notice, the EPA informed IAA that the EPA believed IAA may be a Potentially Responsible Party ("PRP") but the EPA did not specify the factual basis for this assertion. At this time, the EPA still has not specified the factual basis for this assertion and has not demanded that IAA pay any funds or take any action apart from responding to the Section 104(e) Information Request. Four PRPs, The Boeing Company, the City of Seattle, the Port of Seattle and King County - the Lower Duwamish Waterway Group ("LDWG"), have funded a remedial investigation and feasibility study related to the cleanup of the LDW Site. In December 2014, the EPA issued a Record of Decision ("ROD"), detailing the final cleanup plan for the LDW Site. The ROD estimated the cost of cleanup to be $342 million , with the plan involving dredging of 105 acres, capping 24 acres, and enhanced natural recovery of 48 acres. The estimated length of the cleanup was 17 years , including 7 years of active remediation, and 10 years of monitored natural recovery. IAA is aware that certain authorities may bring natural resource damage claims against PRPs. On February 11, 2016, IAA received a Notice of Intent letter from the United States National Oceanic and Atmospheric Administration informing IAA that the Elliott Bay Trustee Council were beginning to conduct an injury assessment for natural resource damages in the LDW. The Notice of Intent indicated that the decision of the trustees to proceed with this natural resources injury assessment followed a pre-assessment screen performed by the trustees. Shortly thereafter, in a letter dated August 16, 2016, EPA issued a status update to the PRPs at the LDW Site. The letter stated that EPA expected the bulk of the pre-remedial design work currently being performed by the LDWG to be completed by the beginning of 2018, with the Remedial Design/Remedial Action ("RD/RA") phase to follow. The EPA previously anticipated that the pre-design work would be completed sometime during 2018, and the Company is not aware of any further information regarding that schedule. Accordingly, RD/RA negotiations with all PRPs may begin sometime in 2019. At this time, the Company has not received any further notices from the EPA and does not have adequate information to determine IAA's responsibility, if any, for contamination at this site, or to estimate IAA's loss as a result of this potential liability. In addition, the Washington State Department of Ecology ("Ecology") is working with the EPA in relation to the LDW Site, primarily to investigate and address sources of potential contamination contributing to the LDW Site. In 2007, IAA installed a stormwater capture and filtration system designed to treat sources of potential contamination before discharge to the LDW Site. The immediate-past property owner, the former property owner and IAA have had discussions with Ecology concerning possible source control measures, including an investigation of the water and soils entering the stormwater system, an analysis of the source of contamination identified within the system, if any, and possible repairs and upgrades to the stormwater system if required. Additional source control measures, if any, are not expected to have a material adverse effect on future recurring operating costs.
