Contingencies [Text Block]	Contingencies We are party to a number of lawsuits, threatened lawsuits and other claims arising out of the normal course of business. With respect to all such matters, we record an accrual for a loss contingency when it is probable that a liability has been incurred and the amount of the loss can be reasonably estimated. If we can only estimate a range of probable loss, an amount representing the low end of the range of probable outcomes is recorded. Management has assessed all such matters, including those described below, based on current information and made a judgment concerning their potential outcome, giving due consideration to the nature of the claim, the amount and nature of damages sought and the probability of success.

Davey Tree Surgery Company--Davey Tree Surgery Company, a subsidiary of The Davey Tree Expert Company, was named as a defendant in Peter Ely et al. v. Davey Tree Surgery Company et al., a purported class-action lawsuit in the State of California filed on July 15, 2008 in the Superior Court of the State of California in and for the County of Alameda. The plaintiffs alleged on behalf of themselves and a putative class that Davey Tree Surgery Company failed to comply with California law concerning off-duty meal periods and the required content of paycheck stubs. The plaintiffs alleged that they and the putative "meal periods" class were not provided with uninterrupted, duty-free 30-minute meal periods. In addition, plaintiffs claimed that because they were allegedly required to work during their meal breaks, Davey Tree Surgery Company violated California's minimum wage law because they and the putative class members were not paid minimum wage for their alleged work during meal breaks. Plaintiffs also contended that Davey Tree Surgery Company violated California law by not including the time that they and the putative "wage statement" class members worked during their meal periods, their hourly rates of pay and the number of hours worked at each hourly rate on their paycheck stubs. The Court granted plaintiffs' motion for class certification and certified both the "meal periods" class and the "wage statements" class; some individuals were members of both classes, while others were members of only one class (collectively, the "class members"). A trial was initially scheduled for January 30, 2012 and was rescheduled to March 26, 2012, pending results of a mediation process initiated in January 2012 with plaintiffs and Local Union 1245 of the International Brotherhood of Electrical Workers (the "Union"). As a result of the mediation, on January 6, 2012, Davey Tree Surgery Company entered into a Settlement Agreement and Release of All Claims (the "Settlement Agreement") with the plaintiffs, counsel for the class members, and the Union representing the class members. The Settlement Agreement requires court approval of its terms. The Court, in April 2012, granted preliminary approval of the Settlement Agreement and set a hearing for final approval on the motion in August 2012. In the event that the Court denies final approval of the Settlement Agreement with prejudice and both Davey Tree Surgery Company and the plaintiffs have exhausted all means to challenge that denial, the Settlement Agreement will be void in all respects and the litigation will continue. The Settlement Agreement provides for Davey Tree Surgery to pay a total sum of $2,900 that was recorded in the fourth quarter 2011.

Contingencies

We are party to a number of lawsuits, threatened lawsuits and other claims arising out of the normal course of business. With respect to all such matters, we record an accrual for a loss contingency when it is probable that a liability has been incurred and the amount of the loss can be reasonably estimated. If we can only estimate a range of probable loss, an amount representing the low end of the range of probable outcomes is recorded.

Management has assessed all such matters, including those described below, based on current information and made a judgment concerning their potential outcome, giving due consideration to the nature of the claim, the amount and nature of damages sought and the probability of success. Management’s judgment is made subject to the known uncertainty of litigation and management’s judgment as to estimates made may prove materially different from actual results.

Ely v. Davey Tree Surgery Company--Davey Tree Surgery Company, a subsidiary of The Davey Tree Expert Company, was named as a defendant in Peter Ely et al. v. Davey Tree Surgery Company et al., a purported class-action lawsuit in the State of California filed on July 15, 2008 in the Superior Court of the State of California in and for the County of Alameda. The plaintiffs alleged on behalf of themselves and a putative class that Davey Tree Surgery Company failed to comply with California law concerning off-duty meal periods and the required content of paycheck stubs.

The plaintiffs alleged that they and the putative "meal periods" class were not provided with uninterrupted, duty-free 30-minute meal periods. In addition, plaintiffs claimed that because they were allegedly required to work during their meal breaks, Davey Tree Surgery Company violated California's minimum wage law because they and the putative class members were not paid minimum wage for their alleged work during meal breaks. Plaintiffs also contended that Davey Tree Surgery Company violated California law by not including the time that they and the putative "wage statement" class members worked during their meal periods, their hourly rates of pay and the number of hours worked at each hourly rate on their paycheck stubs.

The Court granted plaintiffs' motion for class certification and certified both the "meal periods" class and the "wage statements" class; some individuals were members of both classes, while others were members of only one

class (collectively, the "class members"). A trial was initially scheduled for January 30, 2012 and was rescheduled to March 26, 2012, pending results of a mediation process initiated in January 2012 with plaintiffs and Local Union 1245 of the International Brotherhood of Electrical Workers (the "Union").

As a result of the mediation, on January 6, 2012, Davey Tree Surgery Company entered into a Settlement Agreement and Release of All Claims (the "Settlement Agreement") with the plaintiffs, counsel for the class members, and the Union representing the class members.

The Settlement Agreement requires court approval of its terms. The Court, in April 2012, granted preliminary approval of the Settlement Agreement and set a hearing for final approval on the motion in August 2012. In the event that the Court denies final approval of the Settlement Agreement with prejudice and both Davey Tree Surgery Company and the plaintiffs have exhausted all means to challenge that denial, the Settlement Agreement will be void in all respects and the litigation will continue.

The Settlement Agreement provides for Davey Tree Surgery to pay a total sum of $2,900 that was recorded in the fourth quarter 2011.
