Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Letters of Credit At December 31, 2023, we were contingently liable to our principal banks in the amount of $94,702 for letters of credit outstanding primarily related to insurance coverage. Surety Bonds In certain circumstances, we have performance obligations that are supported by surety bonds in connection with our contractual commitments. Litigation We are party to a number of lawsuits, threatened lawsuits and other claims arising out of the normal course of business. On a quarterly basis, we assess our liabilities and contingencies in connection with outstanding legal proceedings utilizing the latest information available. Where it is probable that we will incur a loss and the amount of the loss can be reasonably estimated, we record a liability in our consolidated financial statements. These accruals may be increased or decreased to reflect any relevant developments on a quarterly basis. Where a loss is not probable or the amount of the loss is not estimable, we do not record an accrual, consistent with applicable accounting guidance. Based on information currently available to us, advice of counsel, and available insurance coverage, we believe that our established accruals are adequate and the liabilities arising from the legal proceedings will not have a material adverse effect on our consolidated financial condition. We note, however, that in light of the inherent uncertainty in legal proceedings, there can be no assurance that the ultimate resolution of a matter will not exceed established accruals. As a result, the outcome of a particular matter or a combination of matters may be material to our results of operations for a particular period, depending upon the size of the loss or our income for that particular period. Georgia Wrongful Death Suit In November 2017, a wrongful death lawsuit was filed in Savannah, Georgia in the State Court of Chatham County (“State Court”) against Davey Tree, its subsidiary, Wolf Tree, Inc. (“Wolf Tree”), a former Davey employee, a Wolf Tree employee, and two former Wolf Tree employees. That complaint, as subsequently amended, alleges various acts of negligence and seeks compensatory damages for the wrongful death of the plaintiff’s husband, a Wolf Tree employee, who was shot and killed in August 2017. In July 2018, a related survival action was filed in Savannah, Georgia by the deceased’s estate against Davey Tree, its subsidiary, Wolf Tree, and four current and former employees, which arises out of the same allegations, seeks compensatory and punitive damages and also includes three Racketeer Influenced and Corrupt Organizations Act (“RICO”) claims under Georgia law seeking treble damages. The 2018 case was removed to the United States District Court for the Southern District of Georgia, Savannah Division (“Federal Court”), on August 2, 2018. The cases were mediated unsuccessfully in December 2018 and the State Court case was originally set for trial on January 22, 2019. However, as discussed below, the two civil cases were ultimately stayed for more than four years. On December 6, 2018, a former Wolf Tree employee pled guilty to conspiracy to conceal, harbor, and shield illegal aliens. On December 21, 2018, the United States Department of Justice (“DOJ”) filed a motion to stay both actions on the grounds that on December 7, 2018, an indictment was issued charging two former Wolf Tree employees and another individual with various crimes, including conspiracy to murder the deceased. The State Court case was stayed on December 28, 2018 and the Federal Court case was stayed on January 8, 2019. On January 29, 2019, the State Court ordered the parties to return to mediation, which occurred on April 17, 2019, but was unsuccessful in resolving the matters. By November 2022, all three of the individually charged defendants had either been convicted at trial or pled guilty to Federal criminal charges in the Federal Court related to their involvement with the murder and other illegal activities. All three criminal defendants have now been sentenced. Since the individual defendants' criminal matters are now resolved, the State Court permitted limited additional discovery and amended motions for summary judgment. The Company’s motion for summary judgment was argued before the State Court in October of 2023 and remains pending. The State Court has set a civil jury trial for the week of July 29 to August 2, 2024. The stay in the Federal Court case was lifted on April 4, 2023. The Company moved to dismiss the alleged civil RICO claims, further filed a motion to stay the case until the motion to dismiss was decided, and moved for partial summary judgment on certain state law claims. The Federal Court granted the Company’s motion to stay discovery pending resolution of the motion to dismiss. The Federal Court has not yet set a trial date. Previously, on December 17, 2018, the United States Attorney's Office for the Southern District of Georgia (“United States Attorney”) informed the Company and Wolf Tree that they are also under investigation for potential civil or other violations of immigration and other laws relating to the subject matters of the criminal investigation referenced above. The Company and Wolf Tree fully cooperated with the investigation. On July 12, 2023, the Company and Wolf Tree entered into a non-prosecution and settlement agreement (the “settlement agreement”) with the United States Attorney’s Office for the Southern District of Georgia and the United States Department of Homeland Security (“DHS”), resolving the investigation for potential violations of immigration and other laws by the Company and Wolf Tree. The United States Attorney recognized that, since August 2017, both the Company and Wolf Tree have fully cooperated with the criminal and civil investigation and, in entering into the settlement agreement, the United States Attorney took into consideration the Company’s and Wolf Tree’s implementation of a significant compliance program. The Company and Wolf Tree agreed to pay $3,984 as part of the settlement agreement, including civil penalties, forfeiture and restitution, an amount the Company and Wolf Tree had previously reserved. The United States Attorney agreed that it will not bring any criminal charges against the Company or Wolf Tree concerning the subject matter of the investigation and released the Company and Wolf Tree from civil liability concerning certain immigration code provisions. The DHS also agreed to release the Company and Wolf Tree from administrative liability relating to the subject matter of the investigation, all of which are subject to standard reservations of rights and certain reserved claims. The settlement agreement closes the investigation by the United States Attorney and DHS. The settlement is not an admission of liability by the Company or Wolf Tree. The civil cases in the State Court of Chatham County in Georgia and the United States District Court for the Southern District of Georgia, Savannah Division relating to the same subject matter, remain pending. In both civil cases, the Company and Wolf Tree have denied all liability and are vigorously defending against the actions. The Company also has retained separate counsel for some of the individual defendants, each of whom has denied all liability and also are vigorously defending the actions. Northern California Wildfire Cases Five lawsuits were filed that name contractors for PG&E Corporation and its subsidiary, Pacific Gas and Electric Company (together, “PG&E”), including Davey Tree, with respect to claims arising from a wildfire event that occurred in Pacific Gas and Electric Company’s service territory in northern California beginning on October 8, 2017. An action was brought on August 8, 2019 in Napa County Superior Court, entitled Walker, et al. v. Davey Tree Surgery Company, et al., Case No. 19CV001194. An action was brought on October 8, 2019 in San Francisco County Superior Court, entitled Abram, et al. v. ACRT, Inc., et. al, Case No. CGC-19-579861. An action was brought on October 7, 2019 in San Francisco Superior Court, entitled Adams, et al. v. Davey Resource Group, Inc., et al., Case No. CGC-19-579828. An action was brought on October 8, 2019 in Sacramento Superior Court, entitled Antone, et al. v. ACRT, Inc. et al., Case No. 34-2019-00266662. An action was brought on October 7, 2019 in Sacramento Superior Court, entitled Bennett, et al. v. ACRT, Inc. et al., Case No. 2019-00266501. Three additional actions were brought on January 28, 2021 in San Francisco County Superior Court, by fire victims represented by a trust (“Plaintiffs’ Trust”), which was assigned contractual rights in the PG&E bankruptcy proceedings. These cases are entitled John K. Trotter, Trustee of the PG&E Fire Victim Trust v. Davey Resource Group, Inc., et al., Case No. CGC-21-589438; John K. Trotter, Trustee of the PG&E Fire Victim Trust v. Davey Resource Group, Inc., et al., Case No. CGC-21-589439; and John K. Trotter, Trustee of the PG&E Fire Victim Trust v. ACRT Pacific, LLC, et al., Case No. CGC-21-589441. On September 22, 2021, the Court granted Davey Tree’s petition to coordinate all cases as a California Judicial Council Coordination Proceeding, In Re North Bay Fire Cases, JCCP No. 4955. As a result of the coordination order, all of the actions were stayed in their home jurisdictions, subject to further court order. In November 2022, Davey Tree filed a cross-complaint against the Plaintiffs’ Trust and PG&E related to the contractual obligations of limitation of liability and hold harmless. Since that time, Davey Tree has dismissed the cross-complaint against PG&E without prejudice. The Plaintiffs’ Trust filed a demurrer which challenged Davey Tree’s claim that the hold harmless provisions in its contracts with PG&E are an obligation of the Plaintiffs’ Trust. In response to the demurrer, Davey Tree filed an amended cross-complaint against the Plaintiffs’ Trust on April 13, 2023. The Plaintiffs’ Trust has since filed another demurrer seeking to dismiss the cross complaint by Davey Tree, and Davey Tree has filed a response. The Plaintiffs’ Trust filed a motion for summary adjudication which challenged the limitation of liability as set forth in the assigned contracts. The Court denied the motion for summary adjudication in an order entered April 12, 2023. At a case management conference in JCCP No. 4955 on February 24, 2022, the Court ordered that Davey Tree and the plaintiffs participate in a mediation. The mediation commenced on October 17, 2022. At a case management conference on September 26, 2023, the parties reported to the Court that they had reached a settlement in principle and needed additional time to work on a long form settlement agreement. The parties jointly requested that the Court continue trial dates and other proceedings while the parties attempt to reach final terms on a global resolution. The Court originally set a trial date for October 2, 2023 involving the claim of the Plaintiffs’ Trust as to the Atlas burn location. On July 26, 2023, based on a joint request by the parties, the Court vacated the October 2, 2023 Atlas trial date and reset the Atlas trial for February 26, 2024, which has been vacated. The Court in the Walker case set a trial date of March 4, 2024 for claims related to the Patrick burn location. Pursuant to the parties’ stipulation, that trial date has been continued to August 19, 2024. Davey Tree has responded to all claims asserted by the plaintiffs in these actions, denying all liability, and is vigorously defending against plaintiffs' alleged claims. However, we believe that a range of losses is probable and we have accrued our best estimate within this range which is also equal to our total coverage limits under our self-insurance and third party insurance providers for the 2017-2018 policy year of $220,000. We believe that any losses would be recovered through our self-insurance and third party insurance providers and have accrued a corresponding insurance recoverable within our Condensed Consolidated Balance Sheet as of December 31, 2023.
